Abstract
Description
Technical Field
[0001] The utility model relates to the field of material feeding, and in particular to a feeding bin with an anti-collision structure. Background Art
[0002] Limestone is the most widely used raw material for producing cement. It has the characteristics of large particle size and high hardness after mining.
[0003] In the design of cement plants, material crushing is the first step in the production process. When limestone is used as the raw material for cement, the first thing to consider is crushing the limestone. The current conventional practice is to use a feeding silo to crush the limestone. The feeding silo is set as a reinforced concrete structure, and the cross-sectional shape of the front wall of the feeding silo is trapezoidal or rectangular. Limestone is poured into the feeding silo so that it falls into the crushing equipment below through the feeding silo.
[0004] Since the limestone obtained by mining has large particle size and high hardness, when the limestone is dumped, it hits the feeding bin and causes great damage to the inner wall structure of the feeding bin. At present, in order to protect the main structure of the feeding bin, the inner wall of the feeding bin is fully paved with steel rails, and the spacing between adjacent steel rails is 200mm. After the use of steel rails, the impact of stone unloading on the concrete bin wall can be alleviated to a certain extent. However, since the steel rails and the bin wall generally adopt a rigid connection method of pre-embedded steel plate welding, in actual use, the limestone hits the front bin wall of the feeding bin most seriously, making the steel rails on the front bin wall of the feeding bin easy to be unwelded, and the durability of the steel rails is poor. In addition, the embedded plate position of the front bin wall of the feeding bin still bears a large impact force, and the bin wall at this position is prone to concrete peeling, and the service life of the feeding bin is not ideal. Utility Model Content
[0005] The utility model aims to provide a feeding bin with an anti-collision structure, wherein a buffer plate is arranged in the feeding bin with the anti-collision structure, and the kinetic energy of the material can be effectively absorbed by the buffer plate to protect the concrete structure of the feeding bin.
[0006] In order to achieve the above-mentioned object, the utility model provides a feeding bin with an anti-collision structure, wherein the feeding bin with an anti-collision structure comprises a feeding bin body and a swingable buffer plate arranged in the feeding bin body;
[0007] The upper end of the buffer plate is flexibly connected to the front wall of the feeding bin body;
[0008] A first gap is provided between the buffer plate and the front wall, and the first gap is 10-20 mm.
[0009] Preferably, a second gap is respectively provided on both sides of the buffer plate and on both sides of the feeding bin body, and the second gap is 10-20 mm.
[0010] Preferably, a hook is provided on the front wall, and the buffer plate is hung in the feeding bin body through the hook.
[0011] Preferably, a first buffer pad is provided on a side of the buffer plate facing away from the front wall.
[0012] Preferably, the first buffer pad is detachably connected to the buffer plate.
[0013] Preferably, a second buffer pad is provided on the front wall.
[0014] Preferably, the hooks are arranged on the upper part of the front wall, and an inspection platform is arranged on the front wall along the positions where the hooks are distributed.
[0015] Preferably, the buffer plate is provided on the wall of the feeding bin body except the front wall.
[0016] Preferably, a steel rail is provided on the wall of the feeding bin body where the buffer plate is not provided.
[0017] Preferably, a stopper for protecting the edge of the feeding bin body is provided on the upper edge of the feeding bin body.
[0018] According to the above technical solution, the utility model sets a buffer plate in the feeding bin body. When materials such as limestone are poured into the feeding bin body, before the materials hit the front wall, they will first hit the buffer plate located in front of the front wall. The material hits the buffer plate, so that the buffer plate can swing in the feeding bin body, which will extend the impact time. Since MV=Ft, it can be seen that the impact duration t can be extended by setting the buffer plate, so that the impact force F of the material on the buffer plate is reduced when the material impulse remains unchanged.
[0019] Therefore, the buffer plate can effectively reduce the impact force when dumping materials. At the same time, under the isolation of the buffer plate, the front wall can also avoid direct collision with the materials. Therefore, the buffer plate can effectively protect the front wall of the feeding silo and extend the service life of the feeding silo.
[0020] In order to ensure that the buffer plate can effectively swing within the feeding silo body, the upper end of the buffer plate is flexibly connected to the front wall of the feeding silo body, so that when the material hits the buffer plate, the entire buffer plate can swing around the connection between it and the front wall. Also, because a first gap is provided between the buffer plate and the front wall, the buffer plate also has a certain swinging stroke, thereby extending the impact time and effectively reducing the impact force F.

[0032] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.
[0033] In the present utility model, unless otherwise stated, directional words contained in the terms such as "inside, upper end, front, both sides, upper part" merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.
[0034] See also Figure 1-3 The feeding bin with an anti-collision structure comprises a feeding bin body 1 and a swingable buffer plate 2 disposed in the feeding bin body 1;
[0035] The upper end of the buffer plate 2 is flexibly connected to the front wall 11 of the feeding bin body 1;
[0036] A first gap is provided between the buffer plate 2 and the front wall 11, and the first gap is 10-20 mm.
[0037] Through the implementation of the above technical solution, a buffer plate 2 is provided in the feeding bin body 1. When materials such as limestone are poured into the feeding bin body 1, before the materials hit the front wall 11, they will first hit the buffer plate 2 located in front of the front wall 11. The material hits the buffer plate 2, so that the buffer plate 2 can swing in the feeding bin body 1, which will extend the impact time. Since MV=Ft, it can be seen that the impact duration t can be extended by providing the buffer plate 2, so that the impact force F of the material on the buffer plate 2 is reduced when the material impulse remains unchanged.
[0038] Therefore, the buffer plate 2 can effectively reduce the impact force when dumping materials. At the same time, under the isolation of the buffer plate 2, the front wall 11 can also avoid direct collision with the materials. Therefore, the buffer plate 2 can effectively protect the front wall 11 of the feeding bin and extend the service life of the feeding bin.
[0039] In order to ensure that the buffer plate 2 can effectively swing in the feeding bin body 1, the upper end of the buffer plate 2 is flexibly connected to the front wall 11 of the feeding bin body 1, so that when the material hits the buffer plate 2, the entire buffer plate 2 can swing around the connection between it and the front wall 11. Because a first gap is provided between the buffer plate 2 and the front wall 11, the buffer plate 2 also has a certain swing stroke. Preferably, the first gap is 10-20mm. Because according to practice, when the first gap is less than 10mm, since the angular velocity of the buffer plate 2 is still very small, the effect of reducing the first gap on t is very obvious, thereby affecting the effect of the buffer plate 2 on reducing the impact force F. However, when the first gap is less than 20mm, since the buffer plate 2 already has a certain angular velocity at this time, the increase in stroke does not bring about an effective increase in time. In fact, correspondingly, with the increase in the angular velocity of the buffer plate 2, the dynamic load borne at the connection between the buffer plate 2 and the front wall 11 is rising sharply. Therefore, the first gap of 10-20mm is most suitable. When the first gap is set to 10-20mm, due to the stroke limitation, on the one hand, the angular velocity of the buffer plate 2 will not be too large. On the other hand, since the angular velocity of the buffer plate 2 is relatively small, the impact time can be effectively extended within a limited stroke, thereby effectively reducing the impact force.
[0040] In one embodiment, the upper end of the buffer plate 2 is flexibly connected to the front wall 11 of the feeding bin body 1 through a rope. Preferably, a bolt can be embedded in the upper part of the front wall 11, and a through hole is provided at the upper end of the buffer plate 2, and one end of the wire rope is fixed to the embedded bolt, for example, the wire rope is looped around the embedded bolt for one circle, and then locked by a buckle, so that the wire rope is firmly sleeved on the embedded bolt to prevent the wire rope from falling off the embedded bolt; the other end of the wire rope passes through the through hole at the upper end of the buffer plate 2, and is also locked by the buckle, so that the flexible connection between the upper end of the buffer plate 2 and the front wall 11 can be completed by using the wire rope.
[0041] In this embodiment, preferably, second gaps are respectively provided on both sides of the buffer plate 2 and both sides of the feeding bin body 1, and the second gaps are 10-20 mm.
[0042] By setting the second gap to 10-20mm, the swing amplitude of the buffer plate 2 can be limited. After being hit by the material, the buffer plate 2 will first swing toward the front wall 11, and then hit the front wall 11 and swing in the opposite direction away from the front wall 11. By limiting the second gap to 10-20mm, the reverse swing stroke of the buffer plate 2 can be limited, so as to prevent the buffer plate 2 from swinging in the reverse direction to obtain a large angular velocity, which will have a great impact on the connection reliability of the connection between the buffer plate 2 and the front wall 11.
[0043] When the material hits the buffer plate 2, a horizontal force component will definitely be generated, so that the buffer plate 2 will not only swing forward and backward, but also shake left and right. Under the action of the second gap, when the buffer plate 2 shakes left and right, it will hit the two sides of the feeding bin body 1. After the inner walls of the two sides of the feeding bin body 1 come into contact with the buffer plate 2, friction will be generated to prevent the buffer plate 2 from continuing to swing. Therefore, setting the second gap can effectively limit the swing amplitude of the buffer plate 2, thereby protecting the connection between the buffer plate 2 and the front wall 11.
[0044] Preferably, the buffer plate 2 can be shaped according to the cross-section of the feeding silo body 1, so that the buffer plate 2 and the walls on both sides of the feeding silo body 1 can cooperate more effectively, and the swing amplitude of the buffer plate 2 can be limited more reliably.
[0045] In this embodiment, preferably, a hook 3 is provided on the front wall 11 , and the buffer plate 2 is hung in the feeding bin body 1 through the hook 3 .
[0046] Another implementation is that a hook 3 is provided on the front wall, and a steel wire rope or iron chain 4 is provided on the buffer plate 2, and a flexible connection between the buffer plate 2 and the front wall 11 is achieved through the steel wire rope or iron chain 4.
[0047] The hook 3 can be configured as a steel beam extending out of the front wall 11 . Preferably, a hole for passing a steel wire rope or an iron chain 4 can be further configured on the steel beam.
[0048] The hook 3 can also be configured as a bolt or the like pre-buried in the front wall 11 .
[0049] In this embodiment, preferably, a first buffer pad 5 is provided on a side of the buffer plate 2 facing away from the front wall 11 .
[0050] In order to protect the buffer plate 2 , a first buffer pad 5 is provided on the side of the buffer plate 2 facing the material.
[0051] When the material hits the buffer plate 2, on the one hand, the first buffer pad 5 can physically isolate the material from the buffer plate 2 to prevent the material from directly hitting the buffer plate 2. On the other hand, the first buffer pad 5 can also absorb part of the kinetic energy of the material by deformation, thereby reducing the impulse of the material when it hits the buffer plate 2.
[0052] Preferably, there are often discarded conveyor belts in the factory, and the conveyor belts can be laid side by side on the upper surface of the buffer plate 2, so that a highly cost-effective first buffer pad 5 can be obtained. The conveyor belt can be fixed to the upper surface of the buffer plate 2 by rivets.
[0053] The first buffer pad 5 may also be configured as an extruded polystyrene board with a thickness of about 50 mm to cushion the impact of materials.
[0054] In this embodiment, preferably, the first buffer pad 5 is detachably connected to the buffer plate 2 .
[0055] Since the material will directly hit the first buffer pad 5 when falling, the first buffer pad 5 may need to be replaced after being used for a period of time. Therefore, preferably, the first buffer pad 5 is configured to be detachably connected to the buffer plate 2.
[0056] In one implementation, the buffer plate 2 is provided with a threaded hole, the first buffer pad 5 is provided with a corresponding through hole, and the first buffer pad 5 is fixed to the buffer plate 2 by bolts.
[0057] In one implementation, the first buffer pad 5 is connected to the buffer plate 2 via rivets. When the first buffer pad 5 needs to be disassembled, the rivets can be removed by destroying the first buffer pad 5 at the connection.
[0058] Preferably, a new first buffer pad 5 is directly installed on the first buffer pad 5 that needs to be replaced. For example, when a discarded belt is used as the first buffer pad 5, the new discarded belt can be re-fixed to the position that needs to be replaced.
[0059] In this embodiment, preferably, a second buffer pad is provided on the front wall 11 .
[0060] A second buffer pad is provided on the front wall 11 to alleviate the collision of the buffer plate 2 with the front wall 11 .
[0061] In this embodiment, preferably, the hook 3 is arranged on the upper part of the front wall 11 , and an inspection platform 6 is provided on the front wall 11 along the position where the hook 3 is distributed.
[0062] The hook 3 can be inspected and the first buffer pad 5 can be replaced through the inspection platform 6 .
[0063] The maintenance platform 6 is arranged around the upper side of the buffer plate 2, and the width of the maintenance platform 6 is set to 600-800 mm. The maintenance platform 6 is supported by a cantilevered steel beam, and a patterned steel plate is laid on it to prevent slipping and provide safety for use. A guardrail 61 is arranged on the open side to facilitate the passage and operation of maintenance personnel, which is economical and practical.
[0064] In this embodiment, preferably, a buffer plate 2 is provided on the wall of the feeding bin body 1 except the front wall 11 .
[0065] According to actual usage, a buffer plate 2 may be provided on the gas wall of the feeding silo body 1 except the front wall 11 to protect the wall of the feeding silo body 1 .
[0066] In this embodiment, preferably, a steel rail 8 is provided on the wall of the feeding bin body 1 where no buffer plate 2 is provided.
[0067] For the wall without the buffer plate 2 , a steel rail 8 can be provided to protect the wall of the feeding bin body 1 .
[0068] In this embodiment, preferably, a wheel stop 7 for protecting the edge of the feeding bin body 1 is provided on the upper edge of the feeding bin body 1 .
[0069] The height and width of the car stopper 7 can be designed based on the ore can all fall into the feeding bin while ensuring the safety of unloading. Usually, the height of the car stopper 7 is set to 500 ~ 800mm. The top and both sides of the car stopper 7 need to be laid with steel plates to prevent the mine car from damaging the car stopper 7.
[0070] The impact of the stone unloading on the edge of the feeding bin body 1 can be mitigated to a certain extent by providing the wheel stopper 7. Preferably, the wheel stopper 7 can be provided only on the feeding side of the feeding bin body 1.
[0071] The feeding bin of the limestone crushing system adopts the feeding bin with the anti-collision structure, which has the advantages of simple manufacturing, convenient construction and convenient disassembly. Among them, the buffer plate 2 can be manufactured and installed on-site by the user unit, which is also convenient for the on-site operator to observe and grasp the material unloading status at any time during use, and judge whether the buffer plate 2 or the first buffer pad 5 needs to be replaced according to the degree of wear of the buffer plate 2. Therefore, the use of the feeding bin with the anti-collision structure can ensure the safety of the concrete structure of the feeding bin and improve the service life of the feeding bin.
[0072] The present invention has been applied and verified in many limestone crushing projects, and has been highly recognized by the majority of owners and operating technicians.
[0073] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments.

In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.
[0075] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
