Description

Technical Field

[0001] The invention relates to the technical field of large-scale storage silos for metallurgical machinery and transportation, and in particular to a device and method for reducing material breakage in a silo. Background Art

[0002] In the material feeding production line, in order to ensure continuous production, it is necessary to store the materials. Among various storage methods, silos are widely used because of their small footprint and good sealing performance. When storing materials in silos, the materials are transported to the top of the silo by a belt conveyor, and the materials fall into the silo freely. The gravitational potential energy of the materials will cause the materials to break. This reduces the utilization rate of the materials. In the prior art, most silos have materials falling into the silo freely. The problem of material breakage cannot be well solved;

[0003] A Chinese patent with publication number CN216103948U discloses a silo crushing reduction device, including an inclined guide channel for providing an inclined guide channel for materials input into the silo body, and a vertical guide channel, which is connected to the discharge port of the inclined guide channel and is used to provide a vertical guide channel. An inclined guide channel is provided for materials input into the silo body through the inclined guide channel, thereby avoiding the traditional method of materials falling freely from the top of the silo and crushing the materials, solving the problem of the huge impact force generated by the falling materials causing damage to the materials themselves and causing losses, and also avoiding the materials from directly contacting the inner wall of the silo body, causing damage to the inner wall of the silo body.

[0004] The silo crushing reduction device of the above-mentioned patent has a limited caliber when restricting the falling of materials. After the materials fall vertically along with the silo crushing reduction device, they will accumulate in one area. In order to allow the materials to be fully spread in the silo, the position of the silo crushing reduction device needs to be continuously adjusted. The overall use of the silo crushing reduction device is relatively time-consuming and labor-intensive. Summary of the invention

[0005] The object of the present invention is to provide a device and method for reducing material breakage in a silo. Through the contraction of a hydraulic telescopic device and the transmission of a long shaft, all material receiving plates laterally distributed inside a limiting cavity can be driven to rotate. The material receiving plates rotate and unfold with a first connecting shaft as the center, so that materials can be stored layer by layer and moved longitudinally downward layer by layer, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a device for reducing material breakage in a silo, comprising a limiting chamber, wherein a material receiving plate is transversely arranged inside the limiting chamber, and a push rod is obliquely welded at the lower end of the material receiving plate, one end of the push rod is rotatably connected to the inner wall of the silo via a first connecting shaft, and a long axis is transversely arranged at the lower end of the limiting chamber, and the long axis and the other end of the push rod are rotatably connected via a second connecting shaft.

[0007] Preferably, a hydraulic telescopic device is provided on one side of the limiting chamber, a connecting block is provided at one end of the hydraulic telescopic device facing the push rod, and a sliding block is provided on the connecting block facing one of the push rods.

[0008] Preferably, the inner recess of the push rod is provided with a sliding rail, and the sliding block is embedded in the sliding rail and is slidably connected with the inner part of the sliding rail.

[0009] Preferably, limiting rods are provided at both ends of the long axis, and reserved cavities are provided on both sides of the limiting cavity, and the interior of the reserved cavity is connected to the clamping groove of the limiting rod.

[0010] Preferably, the limiting rod has a rectangular shape.

[0011] Preferably, the limiting chambers are uniformly distributed longitudinally inside the silo.

[0012] The present invention provides another technical solution: a method for reducing material breakage in a silo, which is implemented based on a device for reducing material breakage in a silo, and comprises the following steps:

[0013] S1: The material is dropped vertically downward from the inside of the silo. There are four restriction chambers evenly distributed vertically inside the silo. There are material receiving plates evenly distributed horizontally inside each restriction chamber. The dropped material contacts the material receiving plate inside the uppermost restriction chamber.

[0014] S2: starting the hydraulic telescopic device, the contraction of the hydraulic telescopic device pulls the connecting block, the connecting block moves laterally through the sliding block to pull the push rod, so that the push rod rotates with the first connecting axis as the center;

[0015] S3: The rotation of the push rod drives the connected material receiving plate to rotate, and the material receiving plate rotates counterclockwise and expands the restriction cavity, so that the material restricted by the upper restriction cavity falls into the upper end of the lower restriction cavity, and the material falls layer by layer.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention has four restriction chambers evenly distributed longitudinally inside the silo, and each restriction chamber has receiving plates evenly distributed transversely inside. The restriction chambers can be wrapped and divided by the receiving plates that are sequentially fitted transversely, and the materials falling from the upper end of the silo will be restricted layer by layer by the restriction chambers, and the receiving plates inside each layer of the restriction chamber can actively pull the receiving plates through the contraction of the hydraulic telescopic device, so that the receiving plates can rotate with the push rod around the first connecting axis as the center of the circle, and the receiving plates inside a single restriction chamber are rotated ninety degrees, so that the materials restricted by the upper restriction chamber can fall into the lower restriction chamber, and the materials fall layer by layer, and the receiving plates inside the restriction chamber can fully wrap the silo, avoiding the need to adjust the wrapping position of the receiving plates with respect to the silo, thereby improving the use efficiency of the equipment, and the materials can also be evenly spread inside the silo to avoid accumulation and bulging of materials at a single position.

[0023] The present invention is further described below in conjunction with specific embodiments.

[0024] like Figure 1 As shown, a device for reducing material breakage in a silo of the present embodiment comprises a restriction chamber 1, which is evenly distributed inside the silo longitudinally, and there are four restriction chambers 1 evenly distributed longitudinally, and a receiving plate 2 is transversely arranged inside each of the four restriction chambers 1, and the receiving plate 2 can restrict the silo layer by layer, and the rotating and unfolding receiving plate 2 can facilitate the falling of the material, and the rotation of the receiving plate 2 can make the uppermost material fall on the receiving plate 2 of the lower layer, and the receiving plate 2 inside each restriction chamber 1 is rotated layer by layer, so that the material can fall longitudinally downward layer by layer;

[0025] like Figure 1 and Figure 2As shown, a push rod 4 is tiltedly arranged at the lower end of the receiving plate 2, and the push rod 4 is welded and fixed to the receiving plate 2, one end of the push rod 4 is rotatably connected to the inner wall of the silo through a first connecting shaft 5, and the receiving plate 2 inside the limiting chamber 1 rotates with the first connecting shaft 5 as the center of the circle at the same time, so that the limiting chamber 1 can be expanded, so that the material at the upper end of the limiting chamber 1 can fall evenly;

[0026] Among them, a long shaft 6 is transversely arranged at the lower end of the limiting cavity 1, and the long shaft 6 is rotatably connected to the other end of the push rod 4 through a second connecting shaft 12. By pulling the long shaft 6, all the push rods 4 in the limiting cavity 1 can be synchronously driven to rotate, so that all the material receiving plates 2 connected to the upper ends of the push rods 4 can be synchronously rotated;

[0027] In addition, if Figure 2 and Figure 4 As shown, a hydraulic telescopic device 3 (hydraulic cylinder or hydraulic push rod) is provided on one side of the limiting chamber 1, a connecting block 7 is provided at one end of the hydraulic telescopic device 3 facing the push rod 4, and a sliding block 9 is provided on the connecting block 7 facing one of the push rods 4, and the sliding block 9 can be pulled by the connecting block 7 through the extension and contraction of the hydraulic telescopic device 3;

[0028] In order to facilitate the push rod 4 to rotate with the first connecting shaft 5 as the center, the push rod 4 is recessed with a sliding rail 8, and the sliding block 9 is embedded in the sliding rail 8 and slidably connected to the inside of the sliding rail 8. The contraction of the hydraulic telescopic device 3 can be pulled by the sliding block 9 to pull the push rod 4. While pulling the push rod 4, the sliding block 9 will slide horizontally in the sliding rail 8;

[0029] In order to improve the stability of the long axis 6 when it is pulled laterally, Figure 2 and Figure 3 As shown, limiting rods 10 are provided at both ends of the long axis 6, and reserved cavities 11 are provided on both sides of the limiting cavity 1. The interior of the reserved cavity 11 is connected to the slot of the limiting rod 10. When the long axis 6 is pulled laterally, the limiting rod 10 will move with the long axis 6, and the reserved cavity 11 will limit the limiting rod 10 to improve the stability of the lateral movement of the long axis 6; the outer shape of the limiting rod 10 is rectangular, and the rectangular limiting rod 10 can improve the stability of the lateral movement of the long axis 6.

[0030] Working principle: When the device is used and materials are stored layer by layer and placed longitudinally to prevent them from falling and breaking, the materials are dropped longitudinally downward from the inside of the silo, and the dropped materials will contact the receiving plate 2 inside the uppermost limiting chamber 1. When the materials are dropped longitudinally downward, the hydraulic telescopic device 3 is started, and the contraction of the hydraulic telescopic device 3 can pull the connecting block 7. The lateral movement of the connecting block 7 can pull the push rod 4 through the sliding block 9. In the process of the sliding block 9 pulling the push rod 4 laterally, the sliding block 9 will slide in the sliding rail 8. Pulling the push rod 4 can make the push rod 4 rotate with the first connecting axis 5 as the center of the circle. One of the push rods 4 pulled by the hydraulic telescopic device 3 will pull the remaining push rods 4 to rotate through the long axis 6. The rotation of the push rod 4 will drive the connected receiving plate 2 to rotate. The receiving plate 2 rotates counterclockwise and expands the limiting chamber 1, so that the material restricted in the upper limiting chamber 1 falls into the upper end of the lower limiting chamber 1.

[0031] In order to further better explain the embodiments of the present invention, a method for reducing material breakage in a silo is also provided, comprising the following steps:

[0032] S1: Four limiting chambers 1 are evenly distributed longitudinally inside the silo, and a material receiving plate 2 is evenly distributed transversely inside each limiting chamber 1, and the limiting chamber 1 can be wrapped and divided by the material receiving plates 2 that are sequentially attached transversely;

[0033] S2: The material falling from the upper end of the silo will be restricted layer by layer by the restriction chamber 1, and the material receiving plate 2 inside each layer of the restriction chamber 1 can actively pull the material receiving plate 2 through the contraction of the hydraulic telescopic device 3, so that the material receiving plate 2 can rotate with the push rod 4 around the first connecting shaft 5 as the center of the circle;

[0034] S3: The receiving plates 2 inside a single limiting chamber 1 are rotated 90 degrees, so that the material confined by the upper limiting chamber 1 can fall into the lower limiting chamber 1, and the material falls layer by layer. The receiving plates 2 inside the limiting chamber 1 can fully wrap the silo, avoiding the need to adjust the wrapping position of the receiving plates 2 relative to the silo, thereby improving the use efficiency of the equipment. The material can also be evenly spread inside the silo, avoiding the accumulation and bulging of materials at a single position.
