Description

Technical Field

[0001] This utility model belongs to the field of grain storage fabric technology, specifically relating to a shallow circular silo buffer deceleration and anti-breakage fabric distribution device. Background Technology

[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.

[0003] The shallow round silo feeder is a key component of the shallow round silo grain storage system. It primarily addresses issues such as automatic grading and grain breakage during the grain feeding process, ensuring the quality and safety of stored grain. Traditional feeding methods in shallow round silos tend to cause plump, heavier grains to accumulate in the center of the grain pile, while lighter, shriveled grains and impurities are distributed around the perimeter, resulting in automatic grading. This grading leads to uneven aeration of the grain pile, causing localized heating and mold growth, thus affecting the overall storage quality of the grain. Furthermore, when grain falls from a height, collisions between grains and impacts against the silo walls and floor easily cause breakage, reducing the commercial value of the grain and making broken grains more susceptible to insect infestation and mold.

[0004] When storing dried corn in shallow circular silos, if corn falls from a height to the bottom of the silo, it will break, affecting storage quality. Broken corn kernels lose their intact protective structure and reduce processing performance. During corn processing, broken corn may affect the normal operation of processing equipment. For example, during milling, broken particles may cause uneven wear on grinding rollers, affecting milling efficiency and flour quality. Currently, a feeder is used to distribute the corn to prevent breakage during storage. However, when storing large quantities of corn, excessively high flow rates can lead to large impacts, inevitably causing corn breakage and affecting its subsequent use. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a shallow circular silo buffer deceleration and anti-breakage feeder, which can effectively reduce the falling height of corn and prevent corn breakage due to excessive height; at the same time, it can effectively reduce the falling speed of corn, further preventing corn breakage, and plays a buffering role in preventing breakage when corn falls, ensuring the integrity of corn and not affecting the storage and later use of corn.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shallow circular silo buffer deceleration and anti-breakage feeder includes a telescopic device, a buffer device, a riser, a receiving plate, a central pipe, a grain retaining plate, an overflow baffle, and a supporting steel pipe. The lower end of the telescopic device is provided with a buffer device.

[0008] The buffer device is provided with a central tube at its lower end, and a number of supporting steel pipes are arranged at intervals around the central tube. A vertical pipe is provided at the lower end of the supporting steel pipe, and the vertical pipes are distributed at intervals around the central tube. A number of receiving plates are arranged obliquely on the central tube and the vertical pipes. An overflow baffle is provided on the receiving plates.

[0009] As a further technical solution, the receiving plate on the central tube is arranged on the periphery of the central tube and is arranged in multiple layers; the receiving plate on the vertical tube is arranged obliquely and is arranged in multiple layers.

[0010] As a further technical solution, the receiving plate on the central tube and the receiving plate on the vertical tube are tilted in opposite directions.

[0011] As a further technical solution, the receiving plate is provided with an inclined groove, and several overflow baffles are arranged at intervals in the inclined groove.

[0012] As a further technical solution, the receiving plate and the overflow baffle are fixedly connected, with one end of the overflow baffle being a plane and the other end being an inclined plane.

[0013] As a further technical solution, several grain-blocking plates are spaced apart on the riser, and the grain-blocking plates are fixedly connected to the riser.

[0014] As a further technical solution, one end of the grain retaining plate faces the receiving plate position on the central tube.

[0015] As a further technical solution, the buffer device is a conical structure, with the conical surface of the conical structure facing the telescopic device.

[0016] As a further technical solution, the telescopic device has a cylindrical structure and a cavity inside.

[0017] As a further technical solution, the supporting steel pipe and the central pipe are fixedly connected.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are:

[0019] This invention utilizes a combination of a riser, receiving plate, central pipe, grain baffle, and overflow baffle to achieve buffering, deceleration, and breakage prevention. Corn flows into the chute via a conveyor, and then into the telescopic device. As the corn falls through the cavity of the telescopic device, it is first buffered by the conical buffer, which slows it down and diverts it to the receiving plate on the central pipe. The corn then continues to slide down the receiving plate, where an overflow baffle causes a certain accumulation of corn. Once the accumulation exceeds the height of the overflow baffle, the corn continues to flow. The flow is slowed down and buffered as the corn moves to the receiving plate on the central tube. The receiving plate then guides the flow, causing the corn to accumulate and further slow down. The corn continues to flow on the receiving plates on the central tube and the vertical tube until it falls to the bottom of the shallow circular silo. This layered descent of the corn reduces its falling height and prevents breakage due to excessive height. It also effectively reduces the falling speed, further preventing breakage and acting as a buffer to prevent breakage during the corn's descent, ensuring the integrity of the corn and not affecting its storage or later use.

[0020] The corn falls layer by layer from the top. During the flow and descent, the corn does not reach the conditions for flow acceleration and gravity acceleration. The lower the falling speed of the corn, the lower the breakage rate. This satisfies the deceleration and buffering effect, ensuring that the breakage rate of the dried corn is within the required range.

[0021] This invention features several grain-blocking plates spaced apart on the riser, with one end of each plate facing the receiving plate on the central pipe. When corn slides down from the receiving plate on the central pipe, the grain is prevented from colliding and splashing outside the feeder during its descent, thereby reducing the grain breakage rate.

[0028] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0029] When storing dried corn in shallow circular silos, if corn falls from a height to the bottom of the silo, it will break, affecting storage quality. Broken corn kernels lose their intact protective structure and reduce processing performance. During corn processing, broken corn may affect the normal operation of processing equipment. For example, during milling, broken particles may cause uneven wear on grinding rollers, affecting milling efficiency and flour quality. Currently, a feeder is used to distribute the corn to prevent breakage during storage. However, when storing large quantities of corn, excessively high flow rates can lead to large impacts, inevitably causing corn breakage and affecting its subsequent use.

[0030] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a shallow circular bin buffer deceleration and anti-breakage material distribution device, such as... Figure 1 As shown, it includes a telescopic device 1, a buffer device 2, a riser 3, a receiving plate 4, a central pipe 5, a grain retaining plate 6, an overflow baffle 7, and a supporting steel pipe 8. The lower end of the telescopic device 1 is equipped with a buffer device 2.

[0031] The buffer device 2 has a central pipe 5 at its lower end, and several supporting steel pipes 8 are arranged at intervals around the central pipe 5. The supporting steel pipes 8 have vertical pipes 3 at their lower ends, and the vertical pipes 3 are distributed at intervals around the central pipe 5. Several receiving plates 4 are arranged obliquely on the central pipe 5, and several receiving plates 4 are arranged obliquely on the vertical pipes 3. Overflow baffles 7 are arranged on the receiving plates 4.

[0032] The system utilizes the riser 3, receiving plate 4, central pipe 5, grain baffle 6, and overflow baffle 7 to achieve buffering, deceleration, and breakage prevention. When corn falls through the cavity of the telescopic device 1, it is first buffered by the buffer device 2. The conical buffer device 2 slows the corn down and diverts it onto the receiving plate 4 on the central pipe 5, allowing it to continue sliding down the plate. An overflow baffle 7 is installed on the receiving plate 4, causing the corn to accumulate there. Once the accumulation exceeds the height of the overflow baffle 7, the corn continues to flow, thus achieving buffering and deceleration. The corn flows onto the receiving plate 4 on the central pipe 5, where it is guided to accumulate and slow down. The corn continues to flow onto the receiving plates 4 on the central pipe 5 and the vertical pipe 3 until it falls to the bottom of the shallow circular silo. This allows the corn to fall layer by layer, reducing its falling height and preventing breakage due to excessive height. It also effectively reduces the falling speed, further preventing breakage and acting as a buffer to prevent breakage during the corn's descent, ensuring its integrity and not affecting its storage or later use.

[0033] The receiving plate 4 on the central tube 5 is arranged around the central tube 5 and has multiple layers; the receiving plate 4 on the vertical tube 3 is arranged obliquely and has multiple layers.

[0034] Specifically, by alternately setting the receiving plates 4 on the central pipe 5 and the vertical pipe 3, the corn can fall layer by layer from the top after sliding down from the buffer device 2. During the flow and descent, the corn does not reach the conditions for flow acceleration and gravity acceleration. The lower the falling speed of the corn, the lower the breakage rate. This satisfies the deceleration and buffering effects, ensuring that the breakage rate of the dried corn is within the required range.

[0035] The receiving plate 4 on the central pipe 5 and the receiving plate 4 on the vertical pipe 3 are inclined in opposite directions. Specifically, by setting the receiving plate 4 on the central pipe 5 and the receiving plate 4 on the vertical pipe 3 in opposite directions, the corn can slide down the receiving plate 4 in sequence until it slides down to the bottom of the shallow circular bin.

[0036] like Figure 3 and Figure 4 As shown, the receiving plate 4 has a rhomboid structure and is provided with an inclined groove. Several overflow baffles 7 are arranged at intervals in the inclined groove. The receiving plate 4 and the overflow baffles 7 are fixedly connected. One end of the overflow baffle 7 is a flat surface and the other end is an inclined surface.

[0037] Specifically, a diamond-shaped inclined receiving plate 4 with an inclination of 25-26 degrees is added around the central tube 5 (the static flow angle of corn on the stainless steel receiving plate 4 is 23-25 ​​degrees). Due to the small inclination, some corn accumulates during the flow, which plays a certain buffering role when the corn falls.

[0038] Specifically, to ensure the structural integrity of the feeder, both the receiving plate 4 and the riser 3 are hexagonal and made of stainless steel. If iron plates were used, they would require painting for corrosion protection, which could contaminate the grain. Stainless steel plates meet the requirements for environmentally friendly grain storage.

[0039] The area of ​​each layer's discharge port is twice the inlet area, meaning the cross-sectional area of ​​the discharge point inside the silo is twice the cross-sectional area of ​​the chute outside the silo. By increasing the diameter of the discharge port, it is ensured that there is no material blockage during material entry. The length of the inclined receiving plate 4 is appropriate, and the height of the vertical discharge point does not exceed 800 mm. The corn falls layer by layer from the top. During the flow and descent, the corn does not reach the conditions for flow acceleration and gravity acceleration, thus satisfying the deceleration and buffering effects, ensuring that the corn breakage rate of the drying tower is within the required range.

[0040] Several grain-blocking plates 6 are installed at intervals on the riser 3, and the grain-blocking plates 6 are fixedly connected to the riser 3. One end of the grain-blocking plate 6 faces the receiving plate 4 on the central pipe 5.

[0041] Specifically, several grain baffles 6 are spaced apart on the riser 3. One end of the grain baffle 6 faces the receiving plate 4 on the central pipe 5. When the corn slides down from the receiving plate 4 on the central pipe 5, it can prevent the grain from colliding and splashing outside the feeder during the falling process, thereby reducing the grain breakage rate.

[0042] The buffer device 2 has a conical structure and is installed on top of the riser 3, below the telescopic pipe, with the conical surface of the conical structure facing the telescopic device 1. Specifically, the buffer device 2 is a conical polyurethane material drop buffer device 2, which ensures that the grain is not broken during the first step of entering the warehouse.

[0043] The expansion joint 1 is a cylindrical structure with an internal cavity. It is designed to prevent damage to the shallow circular silo structure caused by thermal expansion and contraction. The expansion joint 1 has two layers, inner and outer, which can expand and contract relative to each other. This existing structure primarily compensates for deformation of the silo caused by temperature changes and material pressure, preventing structural damage, adapting to deformation requirements, mitigating shell expansion and contraction caused by thermal expansion and contraction and material accumulation pressure, and preventing problems such as weld cracking and bolt loosening.

[0044] Specifically, the telescopic device 1 (telescopic length between 120mm and 200mm) can prevent the fabric spreader from thermal expansion and contraction and settling, thereby preventing damage to the shallow circular bin-shaped structure.

[0045] The supporting steel pipe 8 and the central pipe 5 are fixedly connected. Specifically, the central pipe 5 is a 219 or 325 pipe, and the spacing of the openings on the pipe is 700mm-900mm. The size of the openings is determined according to the type of grain being fed in, which effectively prevents sand and slag from entering the central pipe 5 and achieves good ventilation.

[0046] Specifically, a discharge pipe with an outward-to-inward flow is installed in the middle of the shallow circular silo. There is a certain space below the central pipe 5 from the ground to facilitate grain discharge. To ensure the structural stability of the discharge pipe, a 325mm diameter stainless steel pipe is used. Holes are opened around the perimeter according to the location of the discharge point. The outer ring is supported by six 89mm stainless steel support pipes 8 in a diamond shape. The 89mm stainless steel support pipes 8 and the 325mm circle are connected by 51mm stainless steel pipes at a 25-degree angle. Each layer is made into a sloping diamond shape to ensure the stability of the discharge cylinder.

[0047] The inner and outer feeding areas are both 2-3 times the area of ​​the grain inlet, effectively preventing grain blockage and ensuring smooth grain feeding. Figure 3 The black part in the middle is the outer ring. Figure 4 The black part in the middle is the inner circle, and the material feeding area gradually increases, making the grain flow more smoothly.

[0048] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
