Description

Technical Field

[0001] This utility model relates to the field of scraper conveyor technology, specifically to a wear-resistant scraper conveyor device for coal preparation. Background Technology

[0002] Currently, scraper conveyors are large-scale conveyor devices that mainly use scraper chains to transport bulk materials in a trough. Scraper conveyors are commonly used in fluidized bed dry coal preparation. When working, scraper conveyors rely on scrapers to push objects under the drive of the chain.

[0003] When a scraper conveyor is running, the scraper blades directly bear the impact and cutting of the material, resulting in rapid wear. When the scraper needs to be disassembled and replaced due to excessive wear, most existing scrapers are fixed with bolts during installation, and tools are needed to turn the bolts to disassemble them, which is inefficient. Without auxiliary tools, manual replacement is not possible. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant scraper conveyor for coal preparation, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wear-resistant scraper conveying device for coal preparation, comprising a scraper seat, wherein a through hole is provided at the bottom end of the scraper seat, and a scraper body is fixedly installed in the recess at the top end of the scraper seat, wherein a ceramic sheet is pasted on the leading edge of the scraper body, and the ceramic sheet is bonded and fixed to the scraper body by acrylic structural adhesive.

[0006] Furthermore, the scraper seat is mounted on the quick-release assembly, which includes a chain with scraper seats installed at equal intervals, and the chain is formed by connecting several chain links end to end and connecting them with pins to form a closed loop.

[0007] Furthermore, the quick-release assembly also includes a chain lug fixedly installed on the side end of the chain link, and a guide groove is provided at the top of the opposite surface of the chain lug, and the guide groove is inserted into the scraper seat.

[0008] Furthermore, the quick-release assembly also includes bolts inserted into the outer sides of the chain lugs at both ends, and the bolts penetrate through the through hole at the bottom end of the scraper seat.

[0009] Furthermore, the quick-release assembly also includes a flat washer fitted onto the tail of the bolt, and the tail of the bolt is threaded with a quick-release nut.

[0010] Furthermore, the chain is rotatably mounted inside the chute, and the chute is a trough structure with an open top.

[0011] Furthermore, a bracket is fixedly installed on the side end of the chute, and a motor is fixedly installed on the outside of the bracket.

[0012] Furthermore, the rotating end of the motor is connected to a head sprocket, and the head sprocket is connected to the tail sprocket at the other end of the chute via a chain.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In use, this utility model involves attaching alumina ceramic sheets to the leading edge of the scraper body. The Mohs hardness of alumina ceramic is much higher than that of the wear-resistant steel material commonly used in scraper bodies. When material particles pass over the cutting edge, the ceramic sheets can effectively resist particle cutting and prevent the metal of the body from being peeled off. This can effectively reduce scraper wear, extend scraper service life, and significantly reduce equipment maintenance costs.

[0015] 2. When using this utility model, the scraper seat is precisely inserted into the top of the opposite side of the chain lugs under the guidance of the guide groove. Then, after the bolt is passed through the bottom hole of the scraper seat, the flat washer and quick-release nut are installed in sequence to achieve fastening. The design of the quick-release nut allows the operator to manually disassemble and assemble the scraper without the aid of tools, which is especially suitable for light-load application scenarios.

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0021] like Figure 3 As shown, a wear-resistant scraper conveying device for coal preparation includes a scraper seat 1, a through hole 2 is provided at the bottom end of the scraper seat 1, and a scraper body 3 is fixedly installed in the recess at the top end of the scraper seat 1. A ceramic piece 4 is pasted at the leading edge of the scraper body 3, and the ceramic piece 4 is bonded and fixed to the scraper body 3 by acrylic structural adhesive.

[0022] The specific operation is as follows: By attaching alumina ceramic sheet 4 to the leading edge of the scraper body 3, the Mohs hardness of alumina ceramic is much higher than that of the wear-resistant steel material commonly used in the scraper body 3. When material particles pass through the cutting edge, the ceramic sheet 4 can effectively resist particle cutting and prevent the metal of the body from being peeled off. This can effectively reduce scraper wear, extend scraper service life, and significantly reduce equipment maintenance costs.

[0023] like Figures 1 to 2 As shown, the scraper seat 1 is mounted on the quick-release assembly 5. The quick-release assembly 5 includes a chain 501 on which the scraper seats 1 are installed at equal intervals. The chain 501 is formed by connecting several chain links 502 end to end and connecting them with pins to form a closed loop. The quick-release assembly 5 also includes chain lugs 503 fixedly installed on the side ends of the chain links 502. The top of the opposite surface of the chain lugs 503 is provided with guide grooves 504, and the guide grooves 504 are inserted into the scraper seat 1. The quick-release assembly 5 also includes bolts 505 inserted into the outside of the chain lugs 503 at both ends. The quick-release assembly 5, which passes through the bottom hole 2 of the scraper seat 1, also includes a flat washer 506 fitted onto the tail of the bolt 505, and a quick-release nut 507 threaded onto the tail of the bolt 505. The chain 501 is rotatably installed inside the chute 6, and the chute 6 is a trough structure with an open top. A bracket 7 is fixedly installed on the side of the chute 6, and a motor 8 is fixedly installed on the outside of the bracket 7. The rotating end of the motor 8 is connected to the head sprocket 9, and the head sprocket 9 is connected to the tail sprocket 10 at the other end of the chute 6 via the chain 501.

Then, after the bolt 505 is passed through the bottom hole 2 of the scraper seat 1, the flat washer 506 and the quick-release nut 507 are installed in sequence to achieve fastening. The design of the quick-release nut 507 allows the operator to manually disassemble and assemble the scraper without the aid of tools, which is especially suitable for light-load application scenarios.

[0025] Working principle: When motor 8 is activated, the head sprocket 9 at one end of the chute 6 drives the tail sprocket 10 at the other end of the chute 6 via chain 501. During operation, material particles are fed into the chute 6 through the top opening. The scraper chain transports the material to the discharge port at the tail of the chute 6, completing the particle conveying process. Alumina ceramic plates 4 are attached to the leading edge of the scraper body 3. The Mohs hardness of alumina ceramic is much higher than that of the wear-resistant steel commonly used in scraper body 3. When material particles pass over the cutting edge, the ceramic plates 4 effectively... Resisting particle cutting and preventing the metal body from being peeled off, it can effectively reduce scraper wear, extend scraper service life, and significantly reduce equipment maintenance costs. Under the guidance of the guide groove 504, the scraper seat 1 is accurately inserted into the top of the opposite side of the chain lugs 503 on both sides. Then, after the bolt 505 is passed through the bottom hole 2 of the scraper seat 1, the flat washer 506 and quick-release nut 507 are installed in sequence to achieve fastening. The design of the quick-release nut 507 allows the operator to manually disassemble and assemble the scraper without the aid of tools, which is especially suitable for light-load application scenarios.
