    PNEUMATIC TRANSFER SYSTEM
    TECHNICAL AREA
    The present invention relates to a pneumatic transfer system for transferring a powdery or granular product, such as cereals or animal feed, from a first storage place to a second storage place, as well as a means of transport. comprising a bucket and equipped with such a pneumatic transfer system.
    STATE OF THE PRIOR ART
    Transporting a powder or granular product requires transferring said product from a storage location to a second storage location.
    Conventionally, the first storage location can first be a skip of a truck containing the product to be unloaded and the second storage location is for example a location at a customer where the product must be unloaded, a silo for example. In this first case, the product must be conveyed from the bucket or other container and pumped back to the silo.
    Alternatively, the first storage location can be a location at a customer where the product is stored and the second storage location is a truck dump body to be loaded with the product. In this second case, the product must be vacuumed from the location and discharged towards the bucket.
    In order to carry out these transfers, it is known to equip the bucket with a pneumatic transfer system. Although such a pneumatic transfer system is effective, it is necessary to find a simpler transfer system.
    STATEMENT OF THE INVENTION
    An object of the present invention is to provide a pneumatic transfer system which is easy to use and which allows use in suction and delivery or delivery only.
    To this end, a pneumatic transfer system is provided for transporting a product, said pneumatic transfer system comprising:
    -a rotary valve comprising a body, two flanks closing the body at each end, a plurality of blades mounted movable in rotation inside the body
    BE2017 / 5654 around an axis of rotation, the body being pierced with a first inlet and a second inlet, one of the flanks being pierced with a tangential inlet, the other flank being pierced with an outlet tangential coaxial with the tangential input and off-axis with respect to the axis of rotation, the inputs being arranged so that there is at least one blade between the two inputs and the tangential input being arranged so that that there is at least one blade between the tangential entry and each of the entries,
    - a transfer set arranged to ensure product supply until the first entry,
    - a pneumatic booster having an air inlet and an outlet for pressurized air pneumatically connected to the tangential inlet,
    a first separator in the form of a first box with a first pipe arranged axially in the upper part of the first box and a second pipe opening tangentially in the upper part of the first box, the bottom part of the first box being pneumatically connected to the second inlet ,
    a second separator in the form of a second box with a first pipe arranged axially in the upper part of the second box and a second pipe opening tangentially in the upper part of the second box and pneumatically connected to the air inlet of the booster,
    a connecting pipe pneumatically connecting the upper part of the first pipe of the first separator and the upper part of the first pipe of the second separator,
    - A plug provided for alternately taking a closed position in which it closes the lower part of the second box or a free position in which it does not close the lower part of the second box.
    Advantageously, the connecting pipe has a section clearly greater than the second pipe.
    Advantageously, the plug takes the form of a cylindrical air filter, a first end of which is closed off by a closure wall.
    The invention also provides a means of transport comprising a pneumatic transfer system according to one of the preceding variants and a bucket comprising a discharge opening and an inlet, in which the transfer assembly is connected to the discharge opening, and the tangential outlet is adapted to be pneumatically connected to the inlet.

    BRIEF DESCRIPTION OF THE DRAWINGS
    The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description of an exemplary embodiment, said description being made in relation to the accompanying drawings, among which:
    Fig. 1 is a rear perspective view of a bucket equipped with a pneumatic transfer system according to the invention, FIG. 2 is a perspective view of the pneumatic transfer system of FIG. 1 in another direction, FIG. 3 is a side view of a detail of the pneumatic transfer system of FIG. 1, and FIG. 4 is a sectional view of a detail of the pneumatic transfer system of FIG. 1.
    DETAILED DESCRIPTION OF EMBODIMENTS
    Fig. 1 shows a pneumatic transfer system 100 fixed to the rear of a bucket 50 of a means of transport and FIG. 2 shows the pneumatic transfer system 100 alone. The means of transport can be a truck, a tractor or any machine carrying a bucket 50 intended to contain a pulverulent or granular product.
    The pneumatic transfer system 100 comprises a rotary valve 102. The rotary valve 102 comprises a cylindrical body 104 around an axis X and two sides 106 which close the body 104 at each end. Fig. 3 shows the rotary lock 102 from the side without one of its sides 106.
    The rotary valve 102 also comprises a plurality of blades 107 which are mounted in a star and movable in rotation around the axis of rotation X inside the body 104. These adjusted blades provide sealing with the stator. The blades 107 extend in planes containing the X axis. The rotation of the blades 107 is obtained by an appropriate motorization system.
    The body 104 is pierced with a first inlet 108 and a second inlet 110. The inlets 108 and 110 are arranged on the body 104 so that in operation, there is always at least one blade 107 present between the two inputs 108 and 110 in order to ensure sealing.
    One of the flanks 106 is also pierced with a tangential entry 112. In the same way, the entries 108 and 110 and the tangential entry 112 are arranged
    BE2017 / 5654 so that in operation there is always at least one blade 107 present between the tangential input 112 and each of the inputs 108 and 110.
    The other side 106 is pierced with a tangential outlet 116 coaxial with the tangential inlet 112. In the embodiment of the invention presented here, the tangential outlet 116 is extended by a drain pipe 118.
    The two inlets 108 and 110 thus open out substantially radially inside the body 104 and the tangential inlet 112 and the tangential outlet 116 open parallel to the axis X but in an offset manner relative to the axis X.
    The first inlet 108 is connected to a discharge opening 52 of the bucket 50, that is to say that a transfer assembly 150 of the pneumatic transfer system 100 provides the connection between the discharge opening 52 and the first entry 108 and thus ensures the supply of product up to the first entry 108.
    The transfer assembly 150 here successively comprises a conveyor 152 which collects the product at the outlet of the discharge opening 52, then a screw 154, of the Archimedes screw type, which transports the product from the conveyor 152 to the first inlet 108 .
    The shape of the transfer assembly 150 depends in particular on the relative positions between the discharge opening 52 and the first inlet 108.
    The pneumatic transfer system 100 also includes a pneumatic booster 56 which has an air inlet and an outlet for pressurized air.
    The tangential inlet 112 is pneumatically connected to the pressurized air outlet of the pneumatic booster 56, here by means of a discharge line 114.
    The second inlet 110 is pneumatically connected to a separation system 160 which is seen in section in FIG. 4.
    The separation system 160 comprises a first separator 162 which takes the form of a cyclone in the form of a first cylindrical box 163 with a first pipe 164 housed inside the first box 163 and disposed axially in the upper part of the first box 163 and a second pipe 165 which opens tangentially at the top of the first box 163.
    The lower part of the first box 163 is pneumatically connected to the second inlet 110 here by means of a transfer pipe 172.
    BE2017 / 5654
    The separation system 160 comprises a second separator 166 which takes the form of a cyclone in the form of a second cylindrical box 167 with a first pipe 168 housed inside the second box 167 and disposed axially in the upper part of the second box 167 and a second pipe 170 which opens tangentially at the top of the second box 167 and which is pneumatically connected to the air inlet of the booster 56.
    The upper part of the first line 164 of the first separator 162 and the upper part of the first line 168 of the second separator 166 are pneumatically connected to each other by a connecting line 169.
    The lower part of the second box 167 is provided with a plug 174 which is removable. The plug 174 is fixed to the second box 167 by any suitable means such as, for example, latches 175. The plug 174 can thus be active and alternately take a closed position in which it closes the lower part of the second box 167 or be inactive and take a free position in which it does not close the lower part of the second box 167 which remains open.
    The inactive position of the plug 174 may correspond to an absence of the plug 174, but as described below, the change in position of the plug 174 is here due to a particular conformation of the latter.
    The operation of the pneumatic transfer system 100 has two modes.
    In the first mode, the product is captured at the transfer assembly 150 at the outlet of the discharge opening 52, and rejected by the tangential outlet 116. This first mode allows the bucket 50 to be emptied to a place of product storage (silo for example).
    In the second mode, the product is captured at the second line 165 and rejected by the tangential outlet 116. In this second mode, the tangential outlet 116 is pneumatically connected to an inlet of the bucket 50 and this second mode allows filling of the bucket 50. In this second mode, the drain pipe 118 is pneumatically connected to the inlet of the bucket 50.
    Of course, the first and second modes are not necessarily linked to the bucket 50, and the pneumatic transfer system 100 can operate outside the use of a bucket 50, for example for transporting a product from a first storage location to a second storage location.
    BE2017 / 5654
    In the first mode, the plug 174 is in the free position, and the outside air is then sucked in until the air inlet of the booster 56 progressing from the bottom of the second box 167, successively through the second separator 166 and the second line 170.
    As mentioned above, in the first mode, the product is captured at the transfer assembly 150 and transferred to the first inlet 108 of the rotary lock 102. The product is then distributed between the blades 107 of the made their rotation.
    The pressurized air from the booster 56 is discharged through the discharge line 114 to the tangential inlet 112 of the rotary lock 102. The pressurized air then passes through the rotary lock 102 to exit via the outlet tangential 116 by carrying the product which it meets between the blades 107.
    The product is then available at the tangential outlet 116 and the drain pipe 118.
    In the second mode, the plug 174 is in the closed position. The outside air and the product are sucked in at the second line 165, then pass through the first separator 162. By passing through the first separator 162, the product is entrained by the cyclone effect and separates from the air by gravity and falls in the lower part of the first box 163 where it progresses to the second inlet 110 of the rotary lock 102 through the transfer line 172. The air which enters the first separator 162 leaves through the first line 164 of the first separator 162, then crossing the connecting line 169, arrives at the first line 168 of the second separator 166. The air then passes through the second separator 166 and exits through the second line 170 of the second separator 166 to reach '' at the air inlet of the booster 56.
    The product is then distributed between the blades 107 due to their rotation.
    The pressurized air from the booster 56 is discharged through the discharge line 114 to the tangential inlet 112 of the rotary lock 102. The pressurized air then passes through the rotary lock 102 to exit via the outlet tangential 116 by carrying the product which it meets between the blades 107.
    The product is then available at the tangential outlet 116 and the drain pipe 118.
    BE2017 / 5654
    If a minimal part of dust is transported with air to the first line 168 of the second separator 166, it will be deposited by gravity in the lower part of the second box 167 and thus will not reach the blower 56.
    The use of the pneumatic transfer system 100 is therefore relatively simple since it suffices to plug or not plug the lower part of the second box 167 to modify the operating mode.
    Depending on the operating mode, the tangential outlet 116 is or is not pneumatically connected to the inlet of the bucket 50, thus the tangential outlet 116 is adapted to be pneumatically connected to the inlet of the bucket 50.
    To ensure better deposition of dust in the second separator 166, the connecting pipe 169 is dimensioned with a section much greater than the second pipe 165, thus the air speed drops, the dust separates from the air and is deposited by gravity at the bottom of the separator 166; these are recovered periodically by removing the plug 174.
    The first pipe 168 of the second separator 166 takes the form of a tube open at its ends and the side wall of which is pierced with numerous cells 176.
    Such an arrangement makes it possible to break the air flow entering through the upper part of the first pipe 168 of the second separator 166 and therefore to promote the deposition by gravity of the product.
    In the embodiment of the invention presented here, the plug 174 takes the form of a cylindrical air filter materialized here by holes 182. A first end of the cylindrical filter is closed by a closure wall 178 while the second end, that is to say that which is not closed by the closure wall 178 is free.
    In the closed position, on the right in Fig. 4, the first end of the plug 174 is placed against the lower part of the second box 167 which is thus closed by the closure wall 178.
    In the free position, on the left in Fig. 4, the second end of the plug 174 is placed against the lower part of the second box 167 which is therefore not closed and is in contact with the outside air through the cylindrical filter.
