Description

Technical Field

[0001] The utility model relates to the technical field of stone particle sorting, in particular to an anti-wear feeding mechanism used for stone particle sorting and dust removal. Background Art

[0002] When the stone is crushed into stone particles, there is a lot of stone powder / dust, which needs to be sorted by dust removal equipment. In the sorting process, a conveying mechanism is usually built to feed the material from the top of the dust removal equipment; a conical hopper is set at the top of the dust removal equipment to convey the material into the conical hopper.

[0003] The existing problem is that, since the stone particles are obtained after being crushed, they have more edges and corners. When sliding down along the inner wall of the conical hopper, it is easy to cause wear of the inner wall of the conical hopper, resulting in frequent replacement of the hopper.

[0004] Based on various situations reported by customers, our company designed a new sorting and dust removal equipment. In order to fully protect the entire equipment, it was divided into multiple patented solutions. This solution only protects the hopper. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide an anti-wear feeding mechanism for stone material sorting and dust removal, which can prevent the inner wall of the conical hopper from wearing and can automatically release the static material layer A to avoid rusting of the inner wall of the conical hopper.

[0006] The purpose of the utility model is achieved through the following technical solutions: an anti-wear feeding mechanism for stone granular material sorting and dust removal, comprising a conical hopper with a large upper part and a small lower part;

[0007] The inner wall of the conical hopper is provided with a plurality of material retaining rings, which are arranged at different heights; and a material storage trough is formed between the material retaining rings and the inner wall of the conical hopper;

[0008] When loading materials into the conical hopper, part of the materials will accumulate in the storage trough and form a stationary material layer A on the inner wall of the conical hopper. Another part of the materials will slide along the surface of the stationary material layer A. This part of the materials is the flowing material layer B for normal sorting. The stationary material layer A prevents the flowing material layer B from wearing the inner wall of the conical hopper.

[0009] As a preferred technical solution of the present application, a plurality of the material retaining rings are fixed to the inner wall of the conical hopper by spot welding.

[0010] As a preferred technical solution of the present application, multiple material retaining rings can be detachably inserted into the inner wall of the conical hopper; multiple insertion rods are fixed at the lower part of the material retaining ring, and corresponding insertion holes are opened on the inner wall of the conical hopper; when the material retaining ring is set on the inner wall of the conical hopper, the corresponding insertion rods are inserted into the corresponding insertion holes.

[0011] As a preferred technical solution of the present application, the lower end of the insertion rod is a threaded end, and the lower end is screwed with a locking nut after passing through the insertion hole.

[0012] As a preferred technical solution of the present application, the insertion rods of all the material retaining rings extend from the insertion holes, and a force-bearing member is arranged on the outside of the conical hopper; the force-bearing member abuts against the lower end of the insertion rod, and the force-bearing member is connected to a vertically arranged lifting mechanism. When the lifting mechanism pushes upward, it drives the force-bearing member to move upward, thereby causing the insertion rod to move upward, and finally creating a gap between all the material retaining rings and the inner wall of the conical hopper, and this gap can release the material in the static material layer A.

[0013] As a preferred technical solution of the present application, the force-bearing member is a conical force-bearing bucket, which is jacketed outside the conical hopper; when the conical force-bearing bucket moves upward, it can simultaneously generate an upward force on all the insertion rods; the lifting mechanism includes a linear push rod motor and a roller, and a roller is installed on the top of the linear push rod motor, and the roller is in contact with the outer wall of the conical force-bearing bucket.

[0014] As the preferred technical solution of the present application, the conical hopper is placed in the upper shell tube, a truncated cross plate is provided in the upper shell tube, and a lifting mechanism is fixed on the truncated cross plate; a hole is opened in the center of the truncated cross plate, the lower end of the conical hopper is placed at the hole for support, and the top of the conical hopper is fixed to the upper end of the upper shell tube through flanged edges.

[0015] The utility model has the following advantages:

[0016] (1) Prevent wear on the inner wall of the conical hopper;

[0017] In the existing conical hopper, when the stone particles with edges enter the conical hopper and are discharged into the dust removal and sorting equipment, the stone particles are very likely to cause wear of the conical hopper, and the frequency of replacing the conical hopper is relatively high;

[0018] In this solution, by setting a plurality of material retaining rings on the inner wall of the conical hopper, when the material flows along the inner wall of the conical hopper, a part of the material will be accumulated in the storage tank to form a static material layer A on the surface of the conical hopper, while the other part of the material is a flowing material layer B. The flowing material layer B flows on the surface of the static material layer A, so that the inner wall of the conical hopper will not be worn;

[0019] (2) It can automatically release the static material layer A, thereby preventing the inner wall of the conical hopper from rusting;

[0020] If the static material layer A accumulates in the storage tank for a long time, it is easy to accumulate moisture, causing the inner wall of the conical hopper to rust. In this solution, all the retaining rings are lifted up together by the lifting mechanism, so that the static material layer A can be released, allowing the inner wall of the conical hopper to dry naturally, thereby avoiding rust.

[0027] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0028] It should be noted that the directions or positional relationships indicated by "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use, or are the directions or positional relationships commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0030] (Example 1)

[0031] like Figure 1As shown, the wear-resistant feeding mechanism for stone material sorting and dust removal proposed in this embodiment includes a conical hopper 10 with a larger upper part and a smaller lower part, and a plurality of material retaining rings 20; a plurality of material retaining rings 20 are arranged on the inner wall of the conical hopper 10, and the plurality of material retaining rings 20 are arranged at different height positions; a material storage trough 21 is formed between the inner wall of the conical hopper 10 and the corresponding material retaining rings 20;

[0032] It should be noted that this solution is mainly for stone particles (other materials can also be fed), and there are problems: since the crushed stone particles have sharp edges, when sliding along the inner wall of the conical hopper 10, it is easy to cause the inner wall of the conical hopper 10 to be worn by the edges of the stone particles; in addition, when the stone particles slide along the inner wall of the conical hopper 10, the speed will increase, which will cause the fixture to wear;

[0033] When working in this scheme: when loading materials into the conical hopper 10, part of the materials will accumulate in the storage trough and this part of the materials will form a static material layer A on the inner wall of the conical hopper 10, and another part of the materials will slide along the surface of the static material layer A, and this part of the materials is the flowing material layer B for normal sorting work; in this way, when the conical hopper 10 is unloading, the flowing material layer B flows on the surface of the static material layer A, and will not cause wear to the inner wall of the conical hopper 10.

[0034] In this embodiment, a plurality of retaining rings 20 are fixed to the inner wall of the conical hopper 10 by spot welding. This method is relatively simple and convenient, but it is not convenient to replace the retaining rings 20 when they are severely worn.

[0035] Alternatively, in this embodiment, a plurality of material retaining rings 20 can be detachably inserted on the inner wall of the conical hopper 10; specifically, a plurality of insertion rods 22 are fixed at the lower part of the material retaining ring 20, and corresponding insertion holes are opened on the inner wall of the conical hopper 10; when the material retaining ring 20 is set on the inner wall of the conical hopper 10, the corresponding insertion rods 22 are inserted into the corresponding insertion holes, and the lower ends of the insertion rods 22 pass through the insertion holes and are screwed with locking nuts.

[0036] (Example 2)

[0037] The wear-resistant feeding mechanism for stone material sorting and dust removal is designed in another way on the basis of the first embodiment, in which the mounting structure of the retaining ring 20 is designed.

[0038] See also Figure 2 to Figure 4 A plurality of insert rods 22 are circumferentially welded at the lower ends of all the retaining rings 20, and corresponding insert holes are opened on the conical hopper 10, and all the insert rods 22 extend from the intended insert holes; in addition, a force-bearing member 30 is arranged on the outer side of the conical hopper 10; the force-bearing member 30 abuts against the lower ends of the insert rods 22, and the force-bearing member 30 is connected to a vertically arranged jacking mechanism 40;

[0039] During operation, when the lifting mechanism 40 is lifted upward, the force bearing member 30 is driven to move upward, so that the insertion rod 22 moves upward, and finally a gap is generated between all the retaining rings 20 and the inner wall of the conical hopper 10, and the gap can release the materials in the static material layer A;

[0040] It should be noted that, under normal circumstances, it is not necessary to release the static material layer A in the storage trough 21; however, if stones are piled up in the storage trough 21 for a long time without being released, the accumulated stones are likely to cause water accumulation and moisture in the storage trough 21, thereby causing the conical hopper 10 to rust; therefore, this embodiment adopts the jacking mechanism 40 and the force-bearing member 30 to automatically release the accumulated static material layer A, which is simple and convenient.

[0041] In this embodiment, the force-bearing member 30 is a conical force-bearing bucket, which is mounted outside the conical hopper 10; when the conical force-bearing bucket moves upward, it can simultaneously generate an upward force on all the insertion rods 22; the lifting mechanism 40 includes a linear push rod motor 41 and a roller 42, and the roller 42 is installed on the top of the linear push rod motor 41, and the roller 42 contacts the outer wall of the conical force-bearing bucket.

[0042] In this embodiment, the conical hopper 10 is placed in the upper shell tube 1, a truncated cross plate 2 is provided in the upper shell tube 1, and a lifting mechanism 40 is fixed on the truncated cross plate 2; a hole is opened in the center of the truncated cross plate 2, and the lower end of the conical hopper 10 is placed at the hole for support, and the top of the conical hopper 10 is fixed to the upper end of the upper shell tube 1 through a flange.

[0043] This article uses specific examples to illustrate the principles and implementation methods of the utility model. The above examples are only used to help understand the core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the utility model, the present invention can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
