Description

Technical Field

[0001] The present invention relates to the technical field of material chutes, and more specifically, to an abrasion-resistant chute. Background Art

[0002] The material chute is an important component in the mechanized transfer project of materials in various metallurgical plants and mines. It is located at the discharge section of material handling equipment such as belt conveyors and vibrating screens, and is used for guiding and transferring materials between front and rear equipment. As Figure 5 shown, traditional material chutes adopt wear-resistant linings or stepped types. Due to the large abrasiveness of some materials, the corners of the stepped chutes are easily worn through, resulting in material dropping. Using such chutes requires regular maintenance, which directly affects the material transportation and inversion efficiency and increases the maintenance workload. Moreover, the stepped chutes are affected by the material transportation distance, and the applicable locations are limited. Summary of the Invention

[0007] An abrasion-resistant chute of the present invention includes a chute body. The inner wall of the chute body is provided with flow-blocking blocks at intervals. The flow-blocking blocks are inclined upward and form an oblique angle with the inner wall of the chute body. The oblique angle accumulates materials, and the accumulated materials and the transported materials form material-on-material abrasion.

[0008] Further, one end of the flow-blocking block is fixedly connected to the receiving surface of the chute body, and the other end of the flow-blocking block is provided with a conical protrusion, and the protruding end of the conical protrusion points to the material flow direction.

[0009] Further, a partition is provided inside the flow-blocking block, and the partition divides the flow-blocking block into an electric control chamber and a crushing chamber.

[0024] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0025] Embodiment 1

[0026] From Figure 1 It can be seen that an anti-wear chute in this embodiment includes a chute body 1. Baffle blocks 2 are arranged at intervals on the inner wall of the chute body 1. The baffle blocks 2 are inclined upward and form an oblique angle with the inner wall of the chute body 1. The oblique angle accumulates materials, and the accumulated materials and the conveyed materials form material grinding against each other.

[0027] From Figure 2 It can be seen that one end of the baffle block 2 is fixedly connected to the receiving surface of the chute body 1, and a conical protrusion 3 is arranged at the other end of the baffle block 2. The protruding end of the conical protrusion 3 points to the material flow direction. The conical protrusion 3 is in direct contact with the material and produces a crushing effect. The conical protrusion 3 is stressed at the tip and is not easily deformed, which can produce a protective effect on the baffle block 2.

[0028] A partition 21 is arranged inside the baffle block 2. The partition 21 divides the baffle block 2 into an electric control chamber 22 and a crushing chamber 23. Feeding ports 231 and discharging ports 232 are respectively opened on both sides of the crushing chamber 23. Electric control valves 233 are arranged at the ports of the feeding ports 231 and the discharging ports 232.

[0029] During the material guiding process, the electric control valves 233 of the feeding ports 231 and the discharging ports 232 are in a normally closed state, and the baffle block 2 exerts a conventional blocking effect;

[0030] After the material guiding is completed, the electric control valves 233 of the feeding ports 231 and the discharging ports 232 are opened, so that the accumulated materials can be discharged smoothly. The baffle block 2 is used as a hollow diversion channel and produces a diversion effect.

[0031] Crushing devices 4 are arranged at intervals on the baffle block 2. The crushing devices 4 are composed of a motor 41, a main shaft 42, and crushing teeth 43. The motor 41 is installed inside the electric control chamber 22. The output end of the motor 4 is sleeved with the main shaft 42. One end of the main shaft 42 penetrates through the partition 21 and extends into the crushing chamber 23. Crushing teeth 43 are arranged on the surface of the main shaft 42.

[0032] At the same time, during the material guiding process, the electric control valves 233 of the feeding ports 231 and the discharging ports 232 can also be opened, and the crushing device 4 is started. The baffle block 2 is used as a crushing tool, so that the material guiding and crushing are carried out synchronously. While the materials are grinding against each other, the materials are crushed by the crushing teeth 43, accelerating the material guiding progress and preventing blockage inside the chute body 1.

[0033] From Figure 3 It can be seen that the crushing teeth 43 are conical crushing teeth. The conical crushing teeth are evenly distributed in a circular array on the outer ring of the main shaft 42. The conical crushing teeth can carry out high-strength crushing work on massive materials.

[0034] From Figure 4 It can be seen that the crushing teeth 43 are annular serrated blades, which are sleeved on the outer ring of the main shaft 42 at intervals. The annular serrated blades can perform high-speed cutting and cracking work on the massive materials.

[0035] The present invention can solve the wear resistance of the chute body 1 and the limitation of the material conveying distance, making it not easy to be worn through, more durable, and having a large application range, increasing the material transportation and reverse efficiency, and reducing the maintenance workload.

[0036] By using the flow-blocking block 2 installed on the receiving surface of the chute body 1, and the flow-blocking block 2 forms a certain angle with the chute body 1, part of the materials can be silted up, so that the silted materials and the conveyed materials form a form of material grinding against each other, thereby preventing the chute body 1 from being worn through. Moreover, this kind of chute body 1 does not have to be made into a stepped shape and can be made at any angle, so that the use of the chute body 1 is not limited by the distance, solving the problem that it is not easy to make a stepped chute for short-distance material conveying. And there are no special requirements for the material chute. As long as it is the diversion and transfer of materials within a certain particle size range, this chute can be used, which has extremely high application value.

[0037] The above schematically describes the present invention and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design a structural manner and an embodiment similar to this technical solution without creative work without departing from the purpose of the present invention, they shall fall within the protection scope of the present invention.
