Description

Technical Field

[0001] This utility model relates to the technical field of metal scrapers for coal mills, and specifically to a metal scraper device for coal mills. Background Technology

[0002] The scraper of the coal mill is installed at the bottom of the grinding disc. Since the grinding disc generates a lot of debris and dust when it rotates, without the action of the scraper, these debris and dust will adhere to the surface of the grinding disc, resulting in an uneven surface and affecting the normal operation of the coal mill.

[0003] Existing technologies generally use integrated scrapers, which require periodic replacement when they are severely worn. This necessitates the removal of the entire scraper, resulting in a large area of ​​waste. Therefore, a metal scraper device for coal mills is proposed, which allows for easy replacement of scrapers in severely worn areas, significantly reducing the replacement area and avoiding material waste. Summary of the Invention

[0004] To address the problems in the existing technology, this utility model provides a metal scraper device for coal mills, which allows for easy replacement of severely worn parts, thereby significantly reducing the replacement area and avoiding material waste.

[0005] The technical solution adopted by this utility model to solve its technical problem is a metal scraper device for a coal mill, including a grinding disc body, a disassembly block, a second disassembly hole, a first mounting hole and a support roller frame. The bottom sides of the grinding disc body are fixed with disassembly support frames by bolts. The bottom surface of the disassembly support frame is provided with concave grooves. Trapezoidal scrapers are engaged at the corresponding concave groove positions on the bottom of the disassembly support frame. Each of the disassembly and assembly support frames is equipped with an L-shaped bracket on one side of the bottom, and each of the inner bottom sides of the support roller frame is connected to an auxiliary support roller via a rotating shaft.

[0006] By adopting the above technical solution, the concave slot at the bottom of the disassembly and assembly support frame is used to allow the trapezoidal scraper to be secured by the disassembly and assembly block, and the first disassembly and assembly hole allows the disassembly and assembly block to be disassembled and assembled through the first mounting hole. When the trapezoidal scraper is severely worn, it can be replaced, thereby greatly reducing the replacement area and avoiding the problem of material waste. The L-shaped bracket is detached and installed by means of the second disassembly and assembly hole on the surface of the disassembly and assembly frame. The auxiliary support roller supported by the inner side of the bottom support roller frame of the L-shaped bracket is parallel to the bottom position of the trapezoidal scraper, so as to achieve the auxiliary support effect during operation. At the same time, the support spring cooperates with the support roller frame to elastically extend and retract when the auxiliary support roller presses over particles and other foreign objects.

[0007] Specifically, each of the trapezoidal scrapers is equipped with a disassembly block at its top.

[0008] By adopting the above technical solution, the trapezoidal scraper is secured in the concave groove using the disassembly block support.

[0009] Specifically, the bottom of both sides of the disassembly and assembly support frame is provided with a first disassembly and assembly hole, and the surface of the disassembly and assembly block is provided with a first mounting hole corresponding to the position of the first disassembly and assembly hole. The disassembly and assembly block is bolted to the first mounting hole and fixed to the first disassembly and assembly hole.

[0010] By adopting the above technical solution, the first disassembly and assembly hole is used to facilitate the disassembly and assembly of the disassembly and assembly block through the first mounting hole. When the trapezoidal scraper is severely worn, it can be replaced, thereby greatly reducing the replacement area and avoiding the problem of material waste.

[0011] Specifically, a second disassembly hole is provided on one side surface of the disassembly support frame corresponding to the L-shaped bracket position.

[0012] By adopting the above technical solution, an L-shaped bracket is used to facilitate the support spring being fixed to one side of the disassembly and assembly support frame.

[0013] Specifically, the L-shaped bracket has a second mounting hole on its surface corresponding to the second disassembly hole, and the L-shaped bracket is bolted to the second mounting hole and the second disassembly hole.

[0014] By adopting the above technical solution, the second disassembly and assembly hole on the surface of the disassembly and assembly support frame is used to facilitate the disassembly and assembly of the L-shaped bracket through the second mounting hole.

[0015] Specifically, each of the L-shaped brackets is equipped with a support roller frame at its bottom, and each of the L-shaped brackets and the support roller frames is evenly fixed with a support spring from left to right through a support block. The auxiliary support rollers are all parallel to the position of the trapezoidal scraper.

[0016] By adopting the above technical solution, the support spring is used in conjunction with the elastic extension and retraction movement of the support roller frame when the auxiliary support roller presses over foreign objects such as particles.
