Description

Technical Field

[0001] This utility model relates to a silo, and more particularly to an IBC polyethylene cone valve movable silo. Background Technology

[0002] A conical valve silo is a device used for storing and transferring mixed materials, widely used in industrial production. It includes a silo body with a top cover and a conical valve at the bottom. During unloading, the silo body is placed on a support, and the operator uses a manual or pneumatic lifting device to open the conical valve at the bottom, allowing the material inside the silo to be discharged into a predetermined storage container. Chinese Patent Publication No. CN117842534A, entitled "An Automatic Unloading Device for a Silo," discloses a silo whose bottom mounting bracket includes a mounting plate. Connecting columns are provided around the mounting plate via mounting beams. In use, the bottom feet of the silo are inserted into the slots of the connecting columns. Silos with this type of bracket not only require separately designed feet for connection to the bracket, increasing the cost and structural complexity of the silo, but also, since silos are generally made of metal, their overall weight is relatively heavy. Combined with the material loaded inside, this further increases the overall weight. Therefore, after prolonged use, the bottom feet are prone to deformation. The deformed support legs make it difficult for the hopper to align with the slots on the support frame, thus increasing the difficulty of loading the hopper. Furthermore, since the support legs at the bottom of the hopper are directly inserted into the slots and are not fixed to the support frame, and the hopper vibrates under the drive of a vibrator to improve unloading efficiency, the continuous vibration can easily cause the hopper to move and misalign with the lifting device. This can prevent the lifting mechanism from tightly engaging with the conical valve, and in severe cases, can even damage the lifting device. Therefore, a new hopper design is needed to solve these problems. Utility Model Content

[0003] To address the technical problems in existing technologies where the silo body requires independent support legs, is difficult to align with the support frame, and is prone to movement during unloading, this utility model provides an IBC polyethylene cone valve mobile silo that does not require independent support legs, is easy to align with the frame, and is not prone to displacement during unloading.

[0004] This utility model discloses an IBC polyethylene conical valve mobile hopper, comprising a frame and a hopper body on the frame. The frame includes a base plate and several support columns fixed to the base plate. The surface of the base plate has a hopper positioning hole penetrating the base plate. A clamping device is provided on the top of each support column. The clamping device includes a bolt mounting plate, a tightening bolt, and a clamping plate. One end of the bolt mounting plate is connected to the support column, and the other end of the bolt mounting plate is provided with a threaded hole. The end of the tightening bolt is threaded into the threaded hole. The clamping plate is located below the bolt mounting plate. The hopper body is made of polyethylene material, and the bottom end of the hopper body is located in the hopper positioning hole. When fixing the hopper body, the end of the tightening bolt passes through the threaded hole and presses the clamping plate against the surface of the hopper body.

[0005] This utility model relates to an IBC polyethylene conical valve mobile hopper, comprising a frame and a hopper body on the frame. The hopper body is made of polyethylene material, which, compared to a hopper body made of stainless steel, is lighter and less expensive while maintaining structural strength, and is also easier to replace and maintain. The frame includes a base plate and several support columns on the base plate. A clamping device is installed at the top of each support column, and the clamping bolts of the clamping device are connected to the support columns via bolt mounting plates. A clamping plate is installed below the clamping device. The clamping device allows operators to press the clamping plate against the top surface of the hopper body using its clamping bolts when fixing the hopper body, thus firmly fixing the bottom of the hopper body into the hopper positioning holes in the base plate. This not only eliminates the need for separate support legs at the bottom of the hopper body, but also prevents the hopper body from shifting on the frame during unloading or transport, thereby preventing it from tipping over or affecting the lifting device. The hopper positioning holes facilitate the alignment and positioning of the hopper body by the operator, eliminating the need for separate supports at the bottom of the hopper body.

[0006] Furthermore, in the IBC polyethylene conical valve movable hopper of this utility model, the base plate is also provided with several inclined support columns. The bottom end of the inclined support column is set on the surface of the base plate, and the top end of the inclined support column is set on the side of the support column. When the hopper is fixed, the side of the hopper is in contact with the surface of the inclined support column.

[0007] The installation of diagonal bracing columns further supports and secures the silo body, preventing it from shifting and affecting feeding or tipping over.

[0008] Furthermore, in the IBC polyethylene conical valve movable hopper of this utility model, the top end of the inclined support column has a slot adapted to the support column, the bottom end of the inclined support column is provided with an insert plate, and the surface of the bottom plate is provided with several insertion holes adapted to the insert plate.

[0009] The numerous insertion holes on the base plate, the insertion plates at the bottom of the diagonal bracing columns, and the slots at the top facilitate quick disassembly and replacement of the diagonal bracing columns by operators, thereby enabling the frame to adapt to more types of warehouses.

[0010] Furthermore, in the IBC polyethylene conical valve movable hopper of this utility model, one end of the clamping plate is provided with a positioning plate that is fixed to the clamping plate and adapted to the side of the hopper body.

[0011] The positioning plates enable the silo to be positioned on the sides, ensuring that the compartments on each frame maintain a uniform angle for easy storage and transport, while also preventing the silo from rotating during unloading. Furthermore, the pressing device of the IBC polyethylene conical valve moving hopper of this utility model also includes a first connecting plate, which is disposed on the top of the support column, and one end of the bolt mounting plate is fixed to the first connecting plate.

[0012] The first connecting plate facilitates the connection of the bolt mounting plate to the top of the support column.

[0013] Furthermore, the pressing device of the IBC polyethylene conical valve moving hopper of this utility model also includes a second connecting plate and a connecting top plate. The first connecting plate and the second connecting plate are both fixed to the connecting top plate. The first connecting plate, the second connecting plate and the connecting top plate surround a connecting sleeve with a bottom opening. The connecting sleeve is fitted onto the top of the support column.

[0014] The second connecting plate and the connecting top plate are designed to surround the first connecting plate to form a connecting sleeve, thereby facilitating the connection of the clamping device to the top of the support column.

[0015] Furthermore, in the IBC polyethylene conical valve movable hopper of this utility model, the support column is an angle steel, and a reinforcing column fixed to the top of the support column is provided. The connecting sleeve is fixed to the reinforcing column by bolts.

[0016] The angle steel support columns reduce the overall weight of the frame, while the reinforcing columns improve the connection strength between the connecting sleeve and the support columns while maintaining the lightweight design of the frame.

[0017] Furthermore, in the IBC polyethylene conical valve movable hopper of this utility model, the base plate includes a rectangular base frame and a hopper positioning seat. The hopper positioning hole is provided on the hopper positioning seat, and a connecting seat is also provided on the hopper positioning seat. The connecting seat is installed at the hopper positioning hole, and the surface of the connecting seat has through holes that are adapted to the bottom of the hopper body.

[0018] The connecting seat allows the bottom of the silo to enter the silo positioning hole more smoothly, preventing the silo surface from being scratched. It also makes the bottom of the silo smoother, which facilitates unloading. In addition, it can also seal the bottom of the silo, preventing materials from entering below through the gap between the bottom of the silo and the silo positioning seat.

Detailed Implementation

[0033] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0034] Example 1: See Figures 1 to 8 The IBC polyethylene conical valve mobile hopper of this embodiment includes a frame and a hopper body 8 on the frame. The frame includes a base plate 1 and several support columns 2 fixed to the base plate. The surface of the base plate has a hopper positioning hole 3 penetrating the base plate. A clamping device 4 is provided on the top of the support columns. The clamping device includes a bolt mounting plate 5, a tightening bolt 6 and a clamping plate 7. One end of the bolt mounting plate is connected to the support column, and the other end of the bolt mounting plate is provided with a threaded hole. The end of the tightening bolt is threaded into the threaded hole. The clamping plate is located below the bolt mounting plate. The hopper body is made of polyethylene material. The bottom end of the hopper body is located in the hopper positioning hole. When fixing the hopper body, the end of the tightening bolt passes through the threaded hole and presses the clamping plate against the surface of the hopper body.

[0035] This utility model relates to an IBC (Intermediate Bulk Container) polyethylene conical valve mobile hopper, comprising a frame and a hopper body on the frame. The hopper body is made of polyethylene material, which, compared to a hopper body made of stainless steel, is lighter and less expensive while maintaining a certain structural strength, and is also easier to replace and maintain. The frame includes a base plate and several support columns on the base plate. A clamping device is installed at the top of the support columns, and the clamping bolts of the clamping device are connected to the support columns through bolt mounting plates. A clamping plate is installed below the clamping device. The clamping device allows the operator to press the clamping plate against the top surface of the hopper body by tightening the bolts when fixing the hopper body, thereby firmly fixing the bottom of the hopper body into the hopper positioning holes in the base plate. This not only eliminates the trouble of installing separate support legs at the bottom of the hopper body, but also prevents the hopper body from shifting on the frame during unloading or transportation, thus preventing it from tipping over or affecting the lifting device during unloading. The positioning holes in the hopper make it easier for operators to align and position the hopper, eliminating the need for a separate support at the bottom of the hopper.

[0036] The silo body is made of polyethylene material, and has openings at both the top and bottom. The top opening of the silo body has a silo cover 9 that is compatible with it, and the bottom opening of the silo body has a cone valve 10 that is compatible with it.

[0037] The upper part of the silo is cube-shaped, while the lower part is conical. The four corners of the cube-shaped upper part of the silo are chamfered with triangles.

[0038] The frame, used to fix the silo, includes a base plate and several supporting columns connected to it. In this embodiment, there are four supporting columns. The base plate includes two channel steels 11, with the front and rear ends of the two channel steels fixed by angle steel to form a rectangular base frame. A silo positioning seat 12 is provided in the middle of the rectangular base frame. The aforementioned silo positioning hole is located in the middle of the silo positioning seat. The silo positioning seat can be placed directly on the two channel steels or fixed to the channel steels by bolts, welding, or other methods. To provide cushioning for the frame, cushioning pads 13 are also provided at the front and rear ends of the channel steels.

[0039] The clamping device is used to press the silo body onto the base plate. It includes a bolt mounting plate connected to the support column, a tightening bolt on the bolt mounting plate, and a clamping plate below the bolt mounting plate. During fixing, the bottom end of the tightening bolt presses the clamping plate against the top surface of the silo body, thereby pressing the silo body onto the base plate.

[0040] The aforementioned bolt mounting plate can be directly fixed to the support column, either by bolts or welding. Alternatively, it can be connected to the support column via a connecting sleeve fitted onto the top of the support column, facilitating the assembly and disassembly of the clamping device. Furthermore, to facilitate the loading and securing of the silo, the top of the support column can be cylindrical. Correspondingly, the connecting sleeve is also cylindrical and compatible with the top of the support column. This allows the clamping device to rotate at a certain angle via the connecting sleeve when securing the silo, avoiding obstruction of the silo and making it easier to load materials onto the silo positioning holes in the bottom plate. After loading, the connecting sleeve can be rotated again to move the clamping plate above the top wall of the silo and secure it.

[0041] The aforementioned clamping plate and bolt mounting plate can be designed separately. In addition, for easy installation and fixing, the clamping plate can be connected to the bolt mounting plate via magnetic connection or flexible connecting wire.

[0042] The following is the specific process of loading the silo onto the frame.

[0043] First, the operator removes the clamping device from the top of the support column so that the bottom of the silo can extend from above the frame into the silo positioning hole in the base plate. Then, the silo is moved above the base plate by the lifting equipment until its bottom end is aligned with the silo positioning hole. After the silo is aligned with the silo positioning hole, the lifting equipment lowers the silo to a predetermined height so that the bottom end of the silo passes through the silo positioning hole and is completely placed on the base plate.

[0044] Afterwards, the operator resets the clamping device and places the clamping plate on the top wall of the silo. Then, the operator uses a wrench or other tools to rotate the tightening bolts, gradually pressing the bottom end of the bolt against the top wall of the silo until the silo and bottom plate are tightly connected. Once the silo is secured, the operator can unload the material using subsequent equipment or store it directly for later use.

[0045] Preferably, the base plate is also provided with a number of diagonal bracing columns 14, the bottom end of the diagonal bracing column is located on the surface of the base plate, and the top end of the diagonal bracing column is located on the side of the support column. When fixing the silo body, the side of the silo body is in contact with the surface of the diagonal bracing column.

[0046] The installation of diagonal bracing columns further strengthens the support of the silo body, preventing it from shifting and affecting feeding or overturning.

[0047] In this embodiment, there are four support columns and four corresponding diagonal braces. The four diagonal braces are evenly distributed around the positioning holes of the hopper, with one end connected to the support column and the other end connected to the base plate. When fixed, the inclined surface of the diagonal brace is tangent to the conical surface of the hopper body, thereby achieving precise support for the hopper body.

[0048] The two ends of the diagonal brace can be fixed to the base plate and support column by means of bolt connection, welding, etc., or can be detached by means of plug-in or snap-fit ​​connection.

[0049] Preferably, the top of the diagonal brace has a slot 15 adapted to the support column, the bottom of the diagonal brace is provided with an insert plate 16, and the surface of the base plate is provided with a plurality of insertion holes 17 adapted to the insert plate.

[0050] The numerous insertion holes on the base plate, the insertion plates at the bottom of the diagonal bracing columns, and the slots at the top facilitate quick disassembly and replacement of the diagonal bracing columns by operators, thereby enabling the frame to adapt to more types of warehouses.

[0051] In this embodiment, the insert plate is rectangular, and the insertion hole is also rectangular. During installation, the operator inserts the insert plate at the bottom of the diagonal brace into the insertion hole, while the slot at the top of the plate engages with the side of the support column. Installation is very convenient. Disassembly is performed by reversing the above steps.

[0052] In this embodiment, the support column is made of angle steel, and the corresponding top groove of the diagonal brace is a V-shaped groove that is adapted to it. By selecting diagonal braces of different angles and lengths, operators can adapt to different models of warehouses, thereby improving the versatility of the frame.

[0053] Preferably, one end of the clamping plate is provided with a positioning plate 18 that is fixed to the clamping plate and adapted to the side of the chamber.

[0054] The positioning plate enables the positioning of the side of the silo body, so that the silos on each fixed frame can always maintain a uniform angle, which facilitates storage and transportation, and at the same time prevents the silo body from rotating when unloading.

[0055] In this embodiment, the positioning plate and the clamping plate are integrally formed. To improve strength, the positioning plate has reinforcing ribs extending to the surface of the clamping plate. The positioning plate and the clamping plate are L-shaped folded plates. When fixed, the bottom surface of the clamping plate is in close contact with the top surface of the chamber, and the positioning plate is in close contact with the chamfered surface of the upper part of the chamber.

[0056] Preferably, the clamping device further includes a first connecting plate 19, which is disposed on the top of the support column, and one end of the bolt mounting plate 5 is fixed to the first connecting plate.

[0057] The first connecting plate facilitates the connection of the bolt mounting plate to the top of the support column.

[0058] In this embodiment, the first connecting plate is made of angle steel. The first connecting plate can be set on the top side of the support column by means of bolts or welding. One end of the bolt mounting plate is fixed to the side of the first connecting plate. In order to improve the strength, the left and right sides of the bolt mounting plate are also provided with wing plates 20 that are fixed to the first connecting plate and the bolt mounting plate.

[0059] Example 2: Reference Figures 9 to 12 The IBC polyethylene conical valve moving hopper in this embodiment is a further improvement on the first embodiment, as described in detail below.

[0060] Preferably, in this embodiment, the IBC polyethylene conical valve moving hopper and the clamping device 4 further include a second connecting plate 21 and a connecting top plate 22. The first connecting plate 19 and the second connecting plate are both fixed to the connecting top plate. The first connecting plate, the second connecting plate and the connecting top plate surround and form a connecting sleeve with a bottom opening. The connecting sleeve is fitted onto the top of the support column 2.

[0061] The second connecting plate and the connecting top plate are designed to surround the first connecting plate to form a connecting sleeve, thereby facilitating the connection of the clamping device to the top of the support column 2.

[0062] Specifically, the second connecting plate is an angle steel similar to the first connecting plate. Both the top of the second connecting plate and the top of the first connecting plate are fixed to the connecting top plate to form a connecting sleeve with an opening at the bottom. When in use, the operator can directly put it on the top of the support column without fixing it with bolts, which facilitates the disassembly and assembly of the clamping device.

[0063] Furthermore, in this embodiment, the wing plate 20 is disposed above the bolt mounting plate 5, and its bottom end is fixed to the bolt mounting plate. The clamping plate 7 and the positioning plate 18 are fixedly disposed on the bottom surface of the bolt mounting plate. A single tightening bolt 6 is threadedly connected to the bolt mounting plate.

[0064] Preferably, the support column is an angle steel, and a reinforcing column 23 fixed to the top of the support column is provided, and the connecting sleeve is fixed to the reinforcing column by bolts.

[0065] The angle steel support columns reduce the overall weight of the frame, while the reinforcing columns improve the connection strength between the connecting sleeve and the support columns while maintaining the lightweight design of the frame.

[0066] Preferably, the base plate 1 includes a rectangular base frame and a hopper positioning seat 12. The hopper positioning hole 3 is provided on the hopper positioning seat, and a connecting seat 24 is also provided on the hopper positioning seat. The connecting seat is installed at the hopper positioning hole.

[0067] The connecting seat allows the bottom of the silo to enter the silo positioning hole more smoothly, preventing the silo surface from being scratched. It also makes the bottom of the silo smoother, which facilitates unloading. In addition, it can also seal the bottom of the silo, preventing materials from entering below through the gap between the bottom of the silo and the silo positioning seat.
