    In a structure for encapsulating articles with viscous compositions such as casting resins, the individual components such as a premixer, a metering pump, a check valve etc., which all are interconnected with each other by pipes or conduits, are embedded in a solid block member and the conduits are formed by channels provided directly in the material of the block member. Thus, i. a., mounting of the individual components as well as of the conduits is considerably facilitated and a uniform temperature level for all components may easily be warranted.

    Claims (2)

    The invention relates to devices for mixing viscous materials of which one can be liquid, and can be used, for example, in the chemical industry. A device for mixing viscous materials is known, comprising a housing and an actuator-mounted agitator 1 located in the housing. A disadvantage of the known device is the lack of mixing efficiency and the periodicity of the process due to the need to turn off the stirrer drive for unloading the mixture and loading materials. The closest to the invention to the technical essence is a device for mixing viscous materials, containing an entire body with a longitudinal cavity bounded by pairs of body bodies made with an inlet channel for the material on one side and an outlet channel on the opposite side, placed in the longitudinal cavity rigid a plate with transverse holes, connected by a rod placed in the hole, which is made in the middle part of one of the walls of the housing, driven by a reciprocating movement audio plate perpendicular to its longitudinal axis 2. The disadvantage of the known device consists in the fact that the volume of the cavity of the known device periodically varies at the input and output rods, which can lead to variations in the pressure pulsing materiesha which will result in insufficient mixing efficiency. In addition, the gland packing will become loose, especially when there is increased pressure in the cavity and one of the mixing materials is chemically or mechanically aggressive. There is also a danger that stagnant zones of non-flowing masses of material will form in the area of the rod or omentum, as a result of which hardening of the material in these zones is possible, which reduces the efficiency of mixing and can lead to breakdown of the device. The purpose of the invention is to increase the efficiency of mixing materials. This goal is achieved by the fact that the walls of the casing are made in the form of two interconnected metal plates, at least one of which is made with a recess limiting the longitudinal cavity, and the device is provided connected to the plate and located on both its sides at the junction of the plate with the rod Elastic membrane ™ by us, secured to the stitches 11 and along the perimeter of the EZ slab of the casing. In addition, each metallic aska slab is made with a recess limiting the longitudinal cavity. The metal plates of the body are arranged vertically, with the material inlet channel being made in the version of a part of the body, and the outlet in the lower part. The membranes are located at a greater distance from the median plane of the longitudinal cavity than the surfaces of the metal plates, limiting them, the specified cavity on the same side. The distance between the plate surface and the inner surface of the metal plate is less than what the plate thickness is . Hz FIG. 1 shows a general view of the device in FIG. 2, a device plate. The device comprises a housing, the parallel walls of which are made in the form of two metal plates 1.2, at least one of which or both are made with notches a, (S on the inner surface bounding the longitudinal cavity A. A. The body positioned vertically according to the device variant, made with material inlet channel 3 on one side and the outlet channel 4 on the opposite side. Plates 1, 2 of the housing are interconnected by bolts 5, and a seal is placed between the plates B. A rigid plate is placed in the longitudinal cavity .7 with transverse holes 8, connected by means of a bolt 9, a forked head 10 with a rod 11 placed in the hole B, which is made in the middle part of one or both of the housing, with the crank 12 and the reciprocating drive motor 13 the plates 7 are perpendicular to its longitudinal axis. On both sides of the plate 7, during its connection with the fork head 10 and the rod 11, elastic membranes 15 are fixed on the lugs 14, fixed along the perimeter in the plates 1, 2 of the housing. . Between flanges 16 and plate 1, 2 seals 1 are placed. Plates 1, 2 can be made with channels for supplying a thermostatic agent (not shown) Membranes 15 are located at a greater distance from the median plane of the longitudinal cavity A than surface B of metal plates 1, 2 limiting the indicated cavity on the same side, and the distance h between the surface of the plate 7 and the surface B of the plates 1, 2 is less than the thickness of the plate 7 "The device works as follows in the Squash material along the inlet channel 3 is fed into the cavity f ,. The plate 7 is brought into reverse-return movement by means of the pig 13 and the crank 12, whereby the plate periodically and alternately touches the surfaces of the plates 1, 2, the material, the passage through the transverse holes 8 of the plate 7, undergoes a strong shift, is divided into separate sections, thanks to which is intensively mixed and discharged through the outflow canal 4 ". The cavity is sealed relative to the drive plate 7 by means of a membrane, thereby eliminating the need to install an omentum. The membrane functions not only more reliably during operation, since there are no parts rubbing against each other, but, in addition, it is possible to install the membrane so close to the cavity wall that nest sections with reduced mass movement will not form, and the possibility of will harden in these sockets and cause problems with the device. This device also makes it possible, through the installation of a second membrane on the other side of a plate provided with transverse holes, to completely eliminate the change in cavity volume, which previously occurred periodically at the entrance and exit of the drive rod and often caused problems with the device to fluctuate the pressure of the material. The integrity of the volume is ensured by the fact that since the plate made with transverse holes is connected to both membranes, when one of the membranes penetrates into the cavity, the other membrane simultaneously leaves the cavity, so that the total volume basically remains constant. For the mixing process, it is usually beneficial if the membrane has a greater distance from the median plane of the cavity than the surface of the metal plate that limits the cavity on this side, as a result of this, especially for materials with very high viscosity, the pressure on the membrane is less as with the material, there is more space to shift in a reciprocating motion provided with transverse holes in the plate. But the distance should not be so large that the already mentioned areas of reduced material motion do not form. For intensive mixing, on the other hand, it is preferable that the distance between the main surface of the plate provided with transverse holes and the surfaces of the metal plate is smaller than the thickness of the plate, as a result of this most of the material in this area will have to pass through the transverse holes of the plate. It is very important for some materials to be mixed that the temperature is kept as even as possible throughout the entire mixing area. For this purpose, it is preferable that the metal plates have channels for the heat transfer medium or coolant, so that the specific desired temperature is communicated to the entire mixing cavity area. by itself for any mixing process, but is especially consistent with its use in a device for filling objects or molds with viscous masses, which consists of a body other working elements such as premixer metering pump, a control valve, which are interconnected with a mixing device, made in the connecting channel body, and wherein, in particular, the apparatus for mixing is installed in a recess formed v.korpuse. The invention provides more efficient mixing of viscous materials as compared with known devices. Claims 1.
