    [Technical scope]
    The present invention relates to a kneading reactor.
    [State of the art]
    In general, a kneading reactor refers to an apparatus that mixes a liquid material with another liquid material, or mixes fine powder with a viscous material and homogenizes raw material to be produced. The kneading reactor comprises: a cylindrical housing provided with an inlet port into which the raw material is introduced and an outlet port from which a product produced by the reaction of the raw material is discharged; a plurality of vanes arranged in the cylindrical housing from the inlet side toward the outlet port side; and a rotating shaft to which the blades are attached. When the paddles are rotated with the rotating shaft, the raw material is mixed in the kneading reactor, and the resulting product is discharged through the discharge port.
    Recently, with the development of new materials and the like, the number of types of the materials has increased, and a demand for improving the mixing ability in the kneading reactor has increased.
    However, the blades used in the conventional kneading reactor have a large occupancy volume in the kneading reactor due to the fact that the blades have edges formed in an arc shape. In addition, the blades rotate eccentrically so that they come into contact with the raw material at a point of contact to facilitate the reaction. Therefore, the reaction of the raw material takes place over a long period of time.
    [Overview of the invention]
    [Problem to be Solved by the Invention]
    An object of the present invention is to provide a kneading reactor capable of introducing a large amount of raw material.
    Furthermore, it is another object of the present invention to provide a kneading reactor which can decrease a reaction time of the raw material.
    Still another object of the present invention is to provide a kneading reactor in which a large amount of raw material can be reacted.
    However, the technical problem solved by the invention is not limited to the objects described above, and other technical problems not described above will be apparent to those skilled in the art from the following description.
    [Means of solving the problems]
    In order to achieve the objects described above, according to one aspect of the present invention, there is provided a kneading reactor comprising: a chamber having a space formed therein for reacting a raw material; first and second rotating shafts rotatably installed in the chamber; and a plurality of blades attached to the outer periphery of the rotating shaft to be rotated therewith and arranged in a longitudinal direction of the rotating shaft, at least a part of the plurality of blades including: a body formed in a shape that has a multitude of corners; a through hole formed at a center point of the body into which the rotary shaft is inserted; and protrusions protruding from the corners and formed in a shape at which at least one edge coincides with a rotating path of the rotating shaft.
    The blade body can be formed in an equilateral triangular shape.
    The protrusion may be formed in an asymmetrical shape with a thicker thickness than that of the body so as to surround the respective corners.
    The chamber may include: a first space formed adjacent to an inlet port into which the raw material is introduced; a second space formed adjacent to the first space; and a third space formed between the second space and an outlet port through which a product produced by the reaction of the raw material is discharged.
    The plurality of blades which are arranged in the first space and in the third space can be arranged at a certain angular distance from one another.
    The blades arranged in the third space can be arranged with the angular spacing in one direction opposite to the blades arranged in the first space.
    The specific angular distance can be 15 °.
    The rotary shaft includes a first rotary shaft; and a second rotating shaft rotating in at least one direction of the same direction and the opposite direction to the rotating direction of the first rotating shaft, wherein the plurality of blades attached to the first rotating shaft and the second rotating shaft are alternately arranged in a longitudinal direction thereof.
    The raw material can be a lactam-containing pyrrolidone.
    [Beneficial Effects]
    According to the embodiments of the present invention, the blades are formed in an equilateral triangle shape with edges formed in a straight line shape so that the blades have a reduced occupancy volume in the chamber, and therefore a large amount of raw material can be introduced.
    Furthermore, according to the embodiments of the present invention, the reaction time with the raw material can be reduced because the blade has a plurality of contact points that can come into contact with the raw material.
    According to the embodiments of the present invention, since the reaction time with the raw material can be decreased, a large amount of the raw material can be reacted in the chamber.

    In descriptions of the embodiments of the present invention, publicly known techniques that are believed to unnecessarily obscure the purpose of the present invention will not be described in detail. Referring to the drawings, like reference numbers indicate similar or corresponding parts throughout the several views. Furthermore, as used in this document, the terms are defined in that the functions are considered for the present disclosure and they can be changed according to the usage or intention of users or operators. Therefore, definitions of the terms should be made in accordance with the entire disclosure set forth herein.
    It is to be understood that the technical spirit and scope of the present invention are defined by the claims appended, and the following embodiments are made only to describe the present invention in an efficient manner to those skilled in the art having a common knowledge of the technical field to which the present invention belongs.
    FIG. 1 is a plan view illustrating a kneading reactor 100 according to an embodiment of the present invention.
    With reference to FIG. 1, the kneading reactor 100 according to the embodiment of the present invention may include a chamber 200, a rotating shaft 300, and blades 400.
    First, the kneading reactor 100 may be a device that performs a reaction of raw material to produce a product. Here, the raw material can be a lactam-containing pyrrolidone, and the product produced by the reaction of these substances can be a bio-nylon. The kneading reactor 100 according to the embodiment of the present invention may be an apparatus used for manufacturing the bio-nylon. However, it is not limited to this.
    The chamber 200 may be a space formed in the kneading reactor to react with the raw material. The chamber 200 may be formed in a longitudinal cylinder shape in a horizontal direction. In addition, the chamber 200 may have an inlet port 210 into which the raw material is introduced and an outlet port 220 through which a product produced by the reaction of the raw material is discharged. Furthermore, the kneading reactor 100 can have at least one screw (not shown) in order to feed the raw material into the chamber 200 and to discharge the resulting product.
    In addition, the chamber 200 may include: a first space S1, which is formed adjacent to the inlet port 210, into which raw material is introduced; a second space S2, which is formed adjacent to the first space S1, and a third space S3, which is formed between the second space S2 and the outlet port 220, through which a product produced by the reaction of the raw material is discharged, which will be explained in more detail below is described.
    The chamber 200 may have at least one rotating shaft 300 rotatably installed therein. The rotation shaft 300 may have a plurality of blades 400 attached to an outer periphery thereof arranged in a longitudinal direction of the chamber 200 so as to be rotated therewith. In addition, two rotating shafts 300 may be installed in the chamber 200. That is, the rotating shaft 300 may include a first rotating shaft 300a and a second rotating shaft 300b that rotates in at least one direction of the same direction and the direction opposite to the rotating direction of the first rotating shaft 300a. Here, the first rotation shaft 300a and the second rotation shaft 300b can rotate in a clockwise direction, and the first rotation shaft 300a and the second rotation shaft 300b can rotate in a counterclockwise direction, but this is not limited to this. When the first rotation shaft 300a rotates in the clockwise direction, the second rotation shaft 300b can rotate in the counterclockwise direction. That is, the directions in which the first rotating shaft 300a and the second rotating shaft 300b rotate may be the same as or different from each other. In the present invention, the paddles 400 are rotated in the same direction by the first rotating shaft 300a and the second rotating shaft 300b, whereby the product can be efficiently manufactured by the reaction of the raw material. Furthermore, the kneading reactor can have a drive unit (not shown) which is coupled to the rotary shaft 300 in order to supply power to the rotary shaft 300.
    The bucket 400 is coupled to the rotation shaft 300 so as to be rotated therewith. In this case, a plurality of blades may be arranged on the rotary shaft in the longitudinal direction thereof.
    The plurality of blades 400 may be attached to the outer periphery of the rotary shaft 300. The plurality of blades 400 may be arranged at a certain interval. Here, the plurality of blades 400 attached to the first rotating shaft 300a and attached to the second rotating shaft 300b may be arranged alternately in a longitudinal direction. That is, the plurality of blades 400 attached to the first rotating shaft 300a and the plurality of blades 400 attached to the second rotating shaft 300b may be arranged alternately in the longitudinal direction.
    When the rotating shaft 300 rotates, the plurality of blades 400 can come into contact with the raw material in the chamber 200 while rotating therewith. In particular, since the bucket 400 has a plurality of protrusions 430, the raw material comes into contact with the protrusions, thereby facilitating reaction of the raw material to produce a product. That is, the blades 400 can continuously come into contact with the raw material, thereby producing a product by facilitating the reaction of the raw material.
    FIG. 2 is a perspective view illustrating a shape of the bucket 400 according to the embodiment of the present invention, and FIG. 3 is a cross-sectional view of the bucket 400 according to the embodiment of the present invention.
    With reference to FIGs. 2 and 3, at least a portion of the plurality of blades 400 may include a body 410, a through opening 420, and protrusions 430.
    The body 410 may be formed in a shape that has a plurality of corners. For example, the body 410 may be formed in an equilateral triangle shape when viewed in an axial direction. The body 410 is formed of an equilateral triangle shape so that it may have a plurality of corners, that is, three corners. Thereby, when the bucket 400 rotates with the rotary shaft 300, a contact reaction can continuously occur over a large area at an interface between the three corners and the raw material.
    Furthermore, the body 410 is formed as an edge which has a straight line shape, so that a larger amount of raw material can be introduced into the chamber 200. Conventionally, the body is formed as an edge with an arch shape, whereby a relatively large volume is occupied in the chamber 200. This allows a relatively small amount of raw material to be introduced into the chamber 200.
    However, according to the embodiment of the present invention, the blade 400 may be formed as an edge having a straight line shape, thereby occupying a relatively small volume in the chamber 200. Therefore, a relatively large amount of raw material can be introduced into the chamber 200. Therefore, the amount of the raw material reacting in the chamber 200 can be increased, and accordingly the amount of the resulting product can be increased.
    The through hole 420 may be formed at a center point of the body 410 so that the rotary shaft 300 is inserted therein. The through hole 420 is formed at a center point of the body 410 so that the bucket 400 can rotate concentrically with the rotation shaft 300 at the center thereof. Accordingly, the bucket 400 rotates concentrically with the rotary shaft 300 at the center thereof, and the corners of the bucket 400, i.e. H. the three corners of the body 410 and the raw material in the chamber 200 can come into contact with each other to facilitate the reaction.
    The protrusion 430 may be formed in a shape that protrudes from the plurality of corners of the body 410, and has at least one edge that coincides with a rotation path of the rotation shaft 300. That is, the protrusion 430 may be formed in an asymmetrical shape with a thicker thickness than that of the body 410 so as to surround the corners. Here, in the case of the projection 430, an edge coinciding with the rotational path of the rotational shaft and an edge surrounding each vertex may differ from one another.
    The protrusion 430 may be a contact point that comes into contact with the raw material. The protrusion 430 is formed in a thicker thickness than that of the body 410 at each vertex, so that the contact area with the raw material can be increased. Thereby, the protrusions 430 can serve to mix the raw material, so that the reaction thereof can take place over a large area to facilitate the reaction.
    In addition, as shown in FIG. 3, has an edge which is formed so that it coincides with the rotational path of the rotary shaft 300. Thus, for example, when a solid product is produced by the reaction, the raw material can be solidified more and more by the reaction. Accordingly, the rotating speed of the rotating shaft can be decreased due to a weight of the product (solid matter). Thus, the protrusion 430 can at least partially coincide with the rotational path of the rotary shaft 300, so that a force acting on the product can be prevented from being greatly reduced. That is, the protrusion 430 can prevent a rotating force of the rotating shaft 300 for rotating the blades 400 from being decreased by the force acting on the product (solid matter), whereby the raw material can be reacted stably.
    FIG. 4 is a plan view illustrating a first space S 1 to a third space S3 of a chamber 200 according to the embodiment of the present invention.
    With reference to FIG. 4, at least two blades 400 from the plurality of blades 400 can be arranged with a specific angular spacing. In particular, the plurality of blades 400 arranged in the first space S1 and the third space S3 may be arranged at a certain angular distance from each other. That is, the blades 400 arranged in the third space S3 may be arranged with the angular distance in a direction opposite to the blades 400 arranged in the first space S1.
    For example, a phase difference at the corners between the vane 400, which is arranged adjacent to the second space S2, and the vane 400, which is arranged adjacent to the inlet port 210, from the plurality of the vanes 400 arranged in the first space S 1 appear. For example, the vane disposed adjacent to the second space S2 is referred to as a first vane 400a, and the vane disposed adjacent to the inlet port 210 is referred to as a second vane 400b. The first blade 400a and the second blade 400b can be arranged with a certain angular distance.
    In addition, a phase difference may occur at the corners between the vane 400 disposed adjacent to the second space S2 and the vane 400 disposed adjacent to the outlet port 220 among the plurality of the vanes 400 disposed in the third space S3 . For example, the vane disposed adjacent to the second space S2 is referred to as a third vane 400c, and the vane disposed adjacent to the outlet port 220 is referred to as a fourth vane 400d. The third blade 400c and the fourth blade 400d can be arranged with a certain angular distance.
    Here, the specific angular distance can be 15 °. That is, the plurality of blades 400 that are arranged in the first space S1 and the third space S3 can be arranged with a difference of 15 ° from one another. Accordingly, the blades 400 arranged in the first space S1 can be arranged at an angular distance of 15 ° according to the number of the blades 400. In addition, the blades 400 arranged in the third space S3 can be arranged at an angular distance of 15 ° according to the number of the blades 400. In other words, the second blades 400b can be arranged at an angular distance of 15 ° from the first blades 400a, and the fourth blades 400d can be arranged at an angular distance of 15 ° from the third blades 400c.
    Furthermore, the third blade 400c and the fourth blade 400d may be arranged with the angular distance in the direction opposite to the first blade 400a and the second blade 400b. That is, the plurality of blades 400 arranged in the third space S3 are arranged with the angular spacing in the direction opposite to the first space S1, whereby the raw material subjected to the reaction while being in contact with the protrusions, is moved to the side of the second space S2. That is, the third space S3 can move the unreacted raw material to the second space S2 side, thus completing the reaction.
    FIG. 5A is a table illustrating the results of comparing a reaction time of the kneading reactor 100 and an amount of raw material occupying the chamber depending on the shape of the blade 400 according to the embodiment of the present invention, FIG. 5B is a graph illustrating a current value with respect to the reaction time of the kneading reactor 100 depending on the shape of the paddle 400 according to the embodiment of the present invention. and FIG. 6 is a cross-sectional view of a blade 1 having a different shape for comparison with the blade 400 according to the embodiment of the present invention.
    First, for a simpler description, the one shown in FIG. The bucket 1 (a conventionally used bucket) shown in FIG. 6 is hereinafter referred to as bucket A, and the bucket 400 according to the embodiment of the present invention is hereinafter referred to as bucket B. In addition, the kneading reactor including a plurality of blades A is referred to as kneading reactor A, and the kneading reactor including the blade B as at least a part of the plurality of blades is referred to as kneading reactor B.
    As shown in FIG. 6, the bucket A has a plurality of corners, the edges of which may be formed in an arc shape, and an opening eccentrically formed therein into which the rotary shaft is inserted to rotate the bucket A. Furthermore, the blade A has a plurality of protrusions protruding from the plurality of corners.
    As described above, the bucket B, which is the bucket according to the embodiment of the present invention, may be formed in an equilateral triangle shape with a plurality of corners. In addition, the through hole into which the rotation shaft 300 is inserted to rotate the bucket B is formed at the center thereof. The protrusions protruding from the plurality of corners have at least one edge that coincides with a rotating path of the rotating shaft 300.
    The results of the comparison of the reaction time in the kneading reactor A and the kneading reactor B and the amount of the raw material in the chamber are shown in FIG. 5A illustrates. Here, the reaction conditions (for example, the size of the chamber, the amount of the raw material to be filled, etc.) of the kneading reactor A and the kneading reactor B are the same.
    With reference to FIG. 5A, a time in which the reaction is completed by the reaction in the kneading reactor A is 330 minutes. In contrast, a time in which the reaction is completed by the reaction in kneading reactor B is 220 minutes. Therefore, in the kneading reactor A, since the plurality of blades are eccentrically rotated, a contact point is formed with the raw material to facilitate the reaction (polymerization). On the other hand, in the kneading reactor B, since the plurality of blades are concentrically rotated around the center of the rotating shaft 300, three points of contact with the raw material are formed to further facilitate the reaction (polymerization). As a result, the kneading reactor B has a plurality of contact points more than the kneading reactor A, so that the reaction (polymerization) time can be reduced.
    Furthermore, in the kneading reactor A and in the kneading reactor B, the proportions of the raw material occupying the chamber in the same size are 50% and 60%, respectively. That is, the volume of the vane A occupying the chamber is greater than that of the vane B. This results in a difference in the amount of raw material occupying the chamber in proportion to the difference in volume between the vane A and B the scoop B. This difference is directly related to the amount of the resulting product. The kneading reactor B can thus produce a product by simplifying the reaction of the raw material over a relatively large area as compared with the kneading reactor A.
    FIG. 5B is a graph illustrating current values versus reaction time between the kneading reactor A having the plurality of blades A and the kneading reactor B having the blade B as at least a part of the plurality of blades.
    With reference to FIG. 5B, the response time is shown on the X axis and the current value is shown on the Y axis.
    When comparing the kneading reactor A with the kneading reactor B, it can be seen that the current value of the kneading reactor A increases rapidly after a certain period of time has passed. Therefore, the kneading reactor A is in an overloaded state due to the weight of the product (solid) after the reaction and therefore requires a lot of force (torque) to rotate. As a result, the current value required to operate the kneading reactor A can increase rapidly.
    On the other hand, the increased current value of the kneading reactor B is lower than that of the kneading reactor A after a certain period of time has passed. The reason is that the kneading reactor B has the projections at least one edge of which coincides with the rotating path of the blade B, in order to rotate the product (solid matter) resulting from the reaction. That is, the protrusions can distribute the force required for the paddle B to rotate the product (solid matter), so that the kneading reactor B needs a relatively small force (torque) to rotate the rotary shaft.
    The kneading reactor 100 according to the embodiment of the present invention can simplify the reaction of the raw material by contacting the plurality of blades 400. In addition, since each of the plurality of blades 400 has the body 410 formed in an equilateral triangle shape, the volume occupied in the chamber 200 is small. Therefore, a relatively large amount of raw material can be introduced into the chamber 200.
    Further, the bucket 400 has the protrusions 430 protruding from the plurality of corners, and the protrusions 430 can stir the raw material so as to be mixed well.
    Furthermore, since the protrusion 430 has at least one edge that coincides with the rotating path of the rotating shaft 300, the rotating force for rotating the blade 400 can be prevented from being decreased, and thereby the reaction of the raw material can be performed stably .
    Accordingly, the kneading reactor 100 according to the embodiment of the present invention can reduce the reaction time of the raw material and increase the amount of the resultant product.
    While the representative embodiments of the present invention have been described in detail, it will be understood by those skilled in the art to which the present invention pertains that various modifications and variations can be made therein without departing from the scope of FIG deviate from the present invention. Accordingly, it is intended that the scope of the present invention not be limited to the embodiments described above, but that it be defined by the appended claims and their equivalents.
