[0002] In the coal conveying industry, a conveyor is a commonly used device for conveying coal materials, and usually multiple conveyors are used to convey coal materials in a relay form in a stepped manner. During the conveying process, the coal materials will continuously impact the coal chute pipe between the head of the upstream conveyor and the tail of the downstream conveyor, causing the impact surface to be frequently worn through and repaired by welding. This not only increases the maintenance cost but also affects the conveying efficiency. In addition, the scouring of the coal materials will also cause the diffusion of coal dust, pollute the working environment of the coal conveying trestle, and increase the risk of spontaneous combustion and explosion of pulverized coal.

[0003] To solve the above problems, there are already some coal chute pipes with abrasion prevention in the prior art, and wear-resistant plates are arranged on the coal flow scouring surface. However, there are the following disadvantages: the installation of the wear-resistant plates is complex, time-consuming and laborious; the grooves of the wear-resistant plates cannot effectively prevent the diffusion of coal dust, and there are still environmental pollution and potential safety hazards.

[0004] Therefore, there is still room for improvement in the prior art, and a more simple, efficient and environmentally friendly coal chute pipe with abrasion prevention is needed. Summary of the Utility Model

[0007] Further preferably, through holes are opened on the coal flow scouring surface of the coal chute pipe, the cavity module is nested inside the through holes, and the periphery of the cavity module is fixedly welded to the coal flow scouring surface of the coal chute pipe.

[0008] Further preferably, the periphery of the nano-ceramic wear-resistant shield is fixedly welded to the edge of the cavity module close to the coal flow scouring surface.

[0009] Further preferably, the honeycomb matrix is welded to the bottom of the cavity module.

[0010] Further preferably, the honeycomb matrix is composed of transverse reinforcing ribs and vertical reinforcing ribs arranged in a criss-cross manner.

[0011] Further preferably, a material guiding trough is provided at the bottom of the coal chute pipe, and a downstream belt is provided at the bottom of the material guiding trough. Coal material enters the material guiding trough through the coal chute pipe, and the material guiding trough conveys the coal material to the downstream belt.

[0012] Further preferably, an upstream belt is provided at the top of the coal chute pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: At the coal material impact part of each coal chute pipe, a cavity module with a honeycomb matrix inside is installed to relieve the direct scouring of the coal material on the coal chute pipe, reduce the frequency of repairing the coal chute pipe by welding, reduce the extra workload caused by coal spillage, and at the same time greatly reduce the diffusion concentration of coal dust in the coal conveying trestle, solve the problem of excessive pulverized coal in the working environment of the coal conveying trestle, reduce the risk of spontaneous combustion and explosion of pulverized coal in the coal conveying trestle, and improve the working environment.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0021] An anti-wear coal chute pipe, comprising a coal chute pipe 4, a cavity module 2 is arranged on the coal chute pipe 4, a nano-ceramic wear-resistant shield 1 is arranged on the cavity module 2 in the direction close to the coal flow scouring surface, and a honeycomb matrix 3 is arranged at the bottom of the cavity module 2.

[0022] In the present utility model, through holes are formed on the coal flow scouring surface of the coal chute pipe 4, and a cavity module 2 is nested inside the through holes. The periphery of the cavity module 2 is fixedly welded to the coal flow scouring surface of the coal chute pipe 4.

[0023] In the present utility model, the periphery of the nano-ceramic wear-resistant shield 1 is fixedly welded to the edge of the cavity module 2 close to the coal flow scouring surface.

[0024] In the present utility model, the honeycomb matrix 3 is welded to the bottom of the cavity module 2.

[0025] In the present utility model, the honeycomb matrix 3 is composed of horizontally arranged reinforcing ribs 31 and vertically arranged reinforcing ribs 32 which are arranged in a criss-cross manner.

[0026] In the present utility model, a material guiding trough 5 is arranged at the bottom of the coal chute pipe 4, and a downstream belt 7 is arranged at the bottom of the material guiding trough 5.

[0027] In the present utility model, an upstream belt 6 is arranged at the top of the coal chute pipe 4.

[0028] Embodiment 1: According to the size of the on-site coal chute pipe 4, the corresponding cavity module 2 and nano-ceramic wear-resistant shield 1 are manufactured. The cavity module 2 is welded and made of ordinary steel. Its width is manufactured according to the size of the on-site coal chute pipe 4, its length is determined according to the size of the on-site coal flow scouring surface, and its thickness is about 6 cm. The cavity module 2 is butted with the through holes on the coal flow scouring surface of the coal chute pipe 4, and the cavity module 2 is nested inside the through holes. The periphery of the cavity module 2 is fixedly welded to the coal flow scouring surface of the coal chute pipe 4 to coincide with the coal flow scouring surface of the coal chute pipe 4. The nano-ceramic wear-resistant shield 1 is covered at one end of the cavity module 2 close to the coal flow scouring surface. The nano-ceramic wear-resistant shield 1 is a silicon metal material containing a certain proportion of metal oxides, with high hardness and wear resistance. The periphery of the nano-ceramic wear-resistant shield 1 is fixedly welded to the edge of the cavity module 2 close to the coal flow scouring surface. The coal material 8 is conveyed from the upstream belt 6 into the coal chute pipe 4, and the coal material 8 scours the nano-ceramic wear-resistant shield 1, relieving the impact of the coal material 8 on the coal chute pipe 4 and reducing the frequency of repair welding of the coal chute pipe 4.

[0029] Embodiment 2: The difference between this embodiment and Embodiment 1 lies in that: a honeycomb matrix 3 arranged in a crisscross pattern is provided inside the chute cavity module 2.

The coal material 8 is conveyed from the upstream belt 6 to the coal chute pipe 4, flows into the feed chute 5 through the coal chute pipe 4, and is conveyed to the downstream belt 7. During the conveying process, the coal material 8 continuously impacts the nano-ceramic wear-resistant shield 1. When the nano-ceramic wear-resistant shield 1 is worn through after long-term scouring, the coal particles enter the chute cavity module 2 through the worn small holes and fill the entire chute cavity module 2. The honeycomb matrix 3 is welded to the bottom of the chute cavity module 2. When the coal particles enter the chute cavity module 2, the honeycomb matrix 3 can effectively keep the coal particles on the coal flow scouring surface of the chute cavity module 2, reducing the frequency of repairing and welding the coal chute pipe 4, extending the service life of the coal chute pipe 4, reducing the maintenance cost, and reducing the extra workload caused by coal spillage.
