Description

Technical Field

[0001] The utility model relates to the technical field of silo unloading, in particular to a shallow circular silo multi-point unloading device. Background Art

[0002] In the field of grain storage, shallow silos are a common storage facility widely used for the storage of granular grains. However, traditional shallow silos are mostly designed for feeding with a central tube or a side wall chute, which results in fewer discharge points and causes serious grading of the material under its own weight. The grading phenomenon not only affects the quality and use effect of the material, but also causes the grain surface in the silo to be uneven and the drop to be large, which is not conducive to the later flattening and fumigation, and may also cause the silo wall to be overloaded, thus posing a potential threat to the structural safety of the silo. In order to solve this problem, although there are some attempts in the existing technology to optimize the material discharge process by improving the unloading device, the effect is often limited and the problem of material grading and silo wall overload cannot be fundamentally solved. Therefore, it is of great significance to develop a new shallow silo unloading device that can evenly unload, reduce material grading and silo wall overload, in order to improve the efficiency of grain storage and ensure the structural safety of the silo. Utility Model Content

[0003] The purpose of the utility model is to provide a shallow circular silo multi-point unloading device to solve the problems raised in the above-mentioned background technology. The present invention utilizes a central drop pipe and a side drop pipe to cooperate with the drop to achieve uniform material stacking and reduce the serious material classification and silo wall unbalanced loading problems existing in the original single drop point.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A multi-point unloading device for a shallow circular silo comprises a distribution bin arranged at a feeding port position above the shallow circular silo, a central dropping pipe is arranged at the bottom of the distribution bin, the central dropping pipe is communicated with a chamber of the distribution bin, the discharge port of the central dropping pipe faces the middle position in the shallow circular silo, the central dropping pipe is used for paving the bottom of the shallow circular silo, a plurality of side chute pipes are arranged on the side wall of the distribution bin obliquely around an axis downward, the side chute is communicated with the chamber of the distribution bin, the free end of the side chute extends toward the side wall of the shallow circular silo, a plurality of dropping ports are opened on the side chute along the length direction, and a pneumatic valve 1 and a pneumatic valve 2 are respectively arranged at the communication position between the central dropping pipe, the side chute and the distribution bin.

[0006] In order to further optimize the utility model, the following technical solutions can be preferably used:

[0007] Preferably, the distribution bin is arranged in the middle of the shallow circular bin, and the side slide pipes are evenly distributed around the distribution bin axis.

[0008] Preferably, a hanger is provided in the shallow silo at a position above the corresponding side slide pipe, the bottom of the hanger is hingedly connected to the side slide pipe, and the top of the hanger is hingedly connected to the shallow silo.

[0011] Preferably, a pneumatic valve three is provided on the side slide pipe at a position corresponding to the drop port.

[0012] Preferably, the side slide pipe and the central drop pipe are both formed by splicing a plurality of unit pipes.

[0013] The utility model of the shallow silo multi-point unloading device realizes the uniform accumulation and unloading of materials in the shallow silo through a series of innovative designs, thereby significantly improving the efficiency and quality of grain storage.

[0014] Specifically, its beneficial effects are mainly reflected in the following aspects:

Multi-point unloading allows the material to be more evenly distributed in the silo, avoiding material accumulation and unbalanced loading problems, thereby improving the use effect of the material and the structural safety of the silo.

[0016] Secondly, by optimizing the design of the side chute, such as setting it downwardly at an angle around the axis, extending the free end toward the side wall of the shallow silo, and opening multiple discharge ports along the length direction, the utility model further enhances the uniformity and flexibility of unloading. This design allows the material to flow more smoothly to various locations in the silo, reducing the blockage and accumulation of materials during the flow process. In addition, the utility model also achieves precise control of the unloading process by introducing control elements such as pneumatic valves. The pneumatic valve can open or close the corresponding discharge port as needed, thereby adjusting the flow rate and flow direction of the material to ensure uniform distribution of the material in the silo. This precise control not only improves the unloading efficiency, but also reduces energy consumption and labor costs.

[0017] Finally, the utility model also realizes the periodic detection of the height of the grain surface in the warehouse by adding monitoring equipment such as radar level meters that are resistant to dust interference. This helps to promptly discover and solve problems such as material accumulation or overloading, and improves the level of intelligence in warehouse management. At the same time, the design of the side chute and the center drop pipe, which are made of unit pipes, is also convenient for disassembly and maintenance of the device, reducing maintenance costs. In summary, the shallow circular silo multi-point unloading device of the utility model has significant beneficial effects in improving grain storage efficiency, ensuring material quality, enhancing the safety of the silo structure, and reducing operation and maintenance costs, and is of great significance for promoting the sustainable development of the grain storage industry.

[0029] A hanger 5 is installed at a position above the side chute in the shallow silo 1, wherein the bottom of the hanger 5 is hingedly connected to the side chute, and the top of the hanger is hingedly connected to the shallow silo.

[0030] In addition, multiple radar level meters 4 are installed on the top of the shallow round silo to periodically detect the height of the grain surface in the silo. They are dust-resistant and can periodically detect the height of the grain surface in the silo. This helps to promptly discover and solve problems such as material accumulation or eccentric loading, and improves the intelligent level of storage management. The bottom of the central drop pipe extends to the bottom of the shallow round silo, which facilitates the accurate positioning of the bottom of the silo at the beginning and reduces the drop difference.

[0031] In this embodiment, the side chute is composed of multiple unit side chute pipes 14, and the central drop pipe is composed of multiple unit drop pipes 13, which is convenient for disassembly and maintenance of the device, reduces maintenance costs, and is convenient for assembly according to the specifications of the specific shallow cylindrical silo to meet diversified customization needs.

[0032] In summary, the device firstly realizes multi-point unloading by installing a distribution bin, a central drop pipe and a plurality of side chute pipes 7, and effectively solves the material classification phenomenon caused by the small number of discharge points in the traditional shallow circular bin. Multi-point unloading allows the material to be more evenly distributed in the bin, avoiding the problem of material accumulation and overloading, thereby improving the use effect of the material and the structural safety of the bin body; secondly, by optimizing the design of the side chute, such as installing it downwardly around the axis, extending the free end to the side wall of the shallow circular bin, and opening a plurality of drop openings along the length direction, the utility model further enhances the uniformity and flexibility of unloading. This design allows the material to flow more smoothly to various positions in the bin, reducing the blockage and accumulation of the material during the flow process. In addition, the utility model also realizes precise control of the unloading process by introducing control elements such as pneumatic valves; each pneumatic valve can open or close the corresponding drop opening as needed, thereby adjusting the flow rate and flow direction of the material to ensure the uniform distribution of the material in the bin.

[0033] The blanking process of this device is:

[0034] In the initial state, the pneumatic valve 1 on the side of the distribution bin is completely closed, and the pneumatic valve 2 at the bottom of the distribution bin is opened. The grain first flows into the central drop pipe through the pneumatic valve 2 at the bottom of the distribution bin, and then falls to the bottom of the bin after slowing down through the central drop pipe to be laid on the bottom. After the bottom is laid, the radar level meter installed on the top of the shallow circular bin periodically detects the height of the grain surface in the bin and transmits a signal to the control system. The control system selects to open the pneumatic valve 1 around the distribution bin and the pneumatic valve 3 on the side slide pipe until the grain surface height in the bin reaches the predetermined height to achieve uniform distribution.
