Stainless steel silo and aluminum alloy silo generally have the advantages of high sealing and light weight, but poor corrosion resistance.
[0003] Existing silos are generally unable to filter the imported raw materials. When there are large impurities or lumps in the raw materials, it is easy to form a blockage at the silo outlet during the discharge of the raw materials, which is inconvenient for users. Utility Model Content
[0004] The purpose of the utility model is to solve or at least alleviate the problem that the existing silos are generally unable to filter the imported raw materials, and when there are large-volume impurities or lumps in the raw materials, blockage is easily formed at the silo outlet during the discharge of the raw materials, which is inconvenient for users.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A silo feed port anti-blocking device comprises a silo body for storing grain particles, the top of the silo body extends upward to form a feed hopper, the feed hopper has two through holes symmetrically provided on opposite side walls, connecting blocks are fixedly connected to the top and bottom walls of the two through holes, a filter screen with a V-shaped structure is provided in the inner cavity of the feed hopper, two ends of the filter screen respectively extend downward to pass through the two through holes and overlap the top of the connecting block located below, a sealing structure is provided on the outside of the through hole, and a reinforcement component is also provided below the filter screen.
[0007] By adopting the above technical scheme, when in use, the user introduces the raw materials into the silo body through the feed hopper.

At this time, impurities and lumps with a diameter larger than the mesh of the filter cannot pass through the filter, and are retained on the upper surface of the filter. At the same time, the filter has an inverted V-shaped structure. The impurities and lumps retained on the upper surface of the filter will slide down along the filter to the position of the blocking plate under the action of their own gravity, preventing impurities and lumps from accumulating on the surface of the filter and affecting the subsequent passage of raw materials. The problem that the existing silos are generally unable to filter the introduced raw materials is avoided as much as possible.

[0009] By adopting the above technical solution, when the user needs to discharge the raw materials in the silo body, the valve installed on the discharge hopper can be opened, and the raw materials are discharged through the discharge hopper under the action of gravity.
[0010] Optionally, a plurality of partitions in an annular structure are obliquely arranged in the inner cavity of the silo body, and the outer ring of the partition is fixedly connected to the inner wall of the silo body.
[0011] By adopting the above technical solution, multiple annular structure partitions are set to support the raw materials on the upper layer, so as to avoid the problem of excessive squeezing of the bottom raw materials and generating high temperature, which easily changes the properties of the raw materials.
[0012] Optionally, a gap is left between the bottom end of the connecting block installed on the top wall of the inner cavity of the through hole and the upper surface of the filter screen for impurities to pass through and be discharged.
[0013] By adopting the above technical solution, when the user opens the blocking structure, impurities on the upper surface of the filter can be discharged through the gap, making it convenient for the user to clean the impurities and lumps in the raw materials.
[0014] Optionally, the blocking structure is a blocking plate embedded in the inner cavity of the through hole, the inner wall of the blocking plate is in contact with the blocking plate, and two sets of bolts are provided on the blocking plate. The two sets of bolts penetrate the blocking plate and are screwed to the two connecting blocks respectively.
[0015] By adopting the above technical solution, a sealing plate is provided to seal the through hole when the raw materials are introduced into the silo body, and a screw connection method is adopted, which not only ensures a stable connection, but also facilitates the user to install and remove the sealing plate.
[0016] Optionally, the reinforcement assembly includes a beam horizontally arranged below the filter screen and fixedly connected to the inner wall of the feed hopper at both ends, and a reinforcement plate with an upper surface in contact with the filter screen is provided above the beam, and both ends of the reinforcement plate are welded to the upper surface of the beam.
[0017] By adopting the above technical solution, a crossbeam and a reinforcement plate are provided to support the lower surface of the filter, thereby improving the impact resistance of the filter.
[0018] Optionally, a plurality of columns are vertically installed between the middle section of the reinforcement plate and the cross beam, and two ends of the columns are fixedly connected to the cross beam and the reinforcement plate respectively.
[0019] By adopting the above technical solution, columns are provided to support the middle section of the reinforcement plate, thereby further improving the supporting performance of the reinforcement plate on the filter screen.
[0020] Optionally, an inclined plate is obliquely arranged between two adjacent columns, and two ends of the inclined plate are respectively welded to the two adjacent columns.
[0021] By adopting the above technical solution, an inclined plate is provided to form a triangular structure together with the column and the crossbeam, thereby greatly improving the stability of the column support.
[0022] In summary, the beneficial effects of this application are as follows:
[0023] The present application adopts the coordinated arrangement of structures such as a feed hopper, a through hole, a filter screen and a sealing plate. After the raw materials enter the feed hopper, they first need to pass through the filter screen installed in the feed hopper. Impurities and lumps with a diameter larger than the mesh of the filter screen cannot pass through the filter screen. Under the action of their own gravity, they will slide down along the filter screen to the position of the sealing plate to prevent impurities and lumps from accumulating on the surface of the filter screen and affecting the subsequent passage of raw materials. The raw materials introduced into the silo body are filtered through the filter screen, and the problem that the existing silos are generally unable to filter the introduced raw materials is avoided as much as possible. When there are large-volume impurities or lumps in the raw materials, it is easy to form a blockage at the silo outlet during the discharge of the raw materials, which is inconvenient for users to use.

At the same time, the filter screen 7 is in a V-shaped structure, and the lumps or impurities retained on the filter screen 7 will slide down along the two ends of the filter screen 7 under the action of their own gravity, and the impurities will be discharged through the through holes 5 opened on the feed hopper 4, so as to prevent the impurities from accumulating on the filter screen 7 and affecting the subsequent passage of raw materials.
[0032] A blocking structure is provided on the outside of the through hole 5 , and the blocking structure is provided to seal the through hole 5 when the raw material is introduced into the silo body 1 , so as to prevent the raw material from being discharged and spilled from the through hole 5 as much as possible.

The inclined plate 13 is arranged to form a triangular structure with the column 11 and the cross beam 10, which greatly improves the stability of the support of the column 11.
[0041] The implementation principle of the present application is as follows: when in use, the user introduces the raw materials into the silo body 1 through the feed hopper 4.
