Description

Technical Field

[0001] This utility model relates to the technical field of coal gangue sintered bricks, specifically to a device for removing and recycling scrap materials from coal gangue sintered bricks. Background Technology

[0002] Coal gangue bricks are primarily composed of coal gangue, a solid waste generated during coal mining and washing. Its main components include Al2O3 and SiO2. Using coal gangue to make bricks not only reduces production costs compared to ordinary clay bricks but also saves land resources and consumes mine waste, making it an environmentally friendly, low-carbon building material. Even the scraps from sintered coal gangue bricks still have some value; discarding them directly without recycling would be a waste of resources. Recycling and crushing these scraps allows them to be reused in the production process, achieving resource recycling and reducing production costs.

[0003] Existing technology typically consists of a motor, pulleys, a main shaft, a moving grinding disc, and a fixed grinding disc. The motor drives the pulley to rotate, which in turn drives the moving grinding disc on the main shaft to rotate, creating a relative rotational motion between the moving and fixed grinding discs. Scrap material enters between the two grinding discs and is crushed and ground under the combined action of pressure, friction, and shearing forces between the two discs. The ground material is then discharged from the gap between the two grinding discs and falls into the feed box below.

[0004] However, the grinding disc is very easy to wear during long-term grinding, and if it needs to be replaced, the entire equipment needs to be disassembled. This utility model solves the above problems. Utility Model Content

[0005] In order to solve the technical problem that the grinding disc is very easy to wear during long-term grinding, and the entire equipment needs to be disassembled if it needs to be replaced, this utility model provides a scrap removal and recycling device for coal gangue sintered bricks.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a scrap removal and recycling device for coal gangue sintered bricks, comprising: a recycling cylinder, an inlet on the top wall of the recycling cylinder, a grinding shaft rotatably connected inside the top wall of the recycling cylinder, the grinding shaft being connected to a grinding wheel, a positioning ring concentrically provided on the outside of the grinding wheel, multiple grinding discs evenly distributed on the upper circumference of the positioning ring, the multiple grinding discs forming an inner conical grinding surface, a bracket provided at the lower part of the positioning ring, the positioning ring, grinding discs, and bracket being connected by bolts, and a gap being left between the outer conical surface of the grinding wheel and the inner conical surface of the grinding discs, the gap gradually decreasing in size from top to bottom.

[0007] Preferably, the grinding shaft and the grinding wheel are hollow, and an agitator is rotatably connected inside the grinding shaft and the grinding wheel. The agitator and the grinding shaft are respectively connected to the power through different transmission mechanisms. The agitator rotates faster than the grinding shaft, and the agitator is connected to the agitator blade.

[0008] Preferably, the grinding wheel has a conical surface on its upper part.

[0009] Preferably, the recycling cylinder is fixed by a frame, and a belt conveyor is provided at the bottom of the recycling cylinder.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. When in use, the lower part of the grinding disc is supported by the bracket to ensure a firm fixation. When replacing the grinding disc, the bracket is removed by unscrewing the bolts. The lower part of the grinding disc, without support and restraint, can rotate to a vertical position with the positioning ring as the fulcrum, and then it can be lifted and removed without interfering with the conical grinding tool. Therefore, the replacement can be completed without the need for complete disassembly.

[0012] 2. Scrap materials and other raw materials enter the grinding gap together for grinding and discharge. After discharge, they fall and are mixed by the high-speed rotating stirring blades, and are discharged by the belt conveyor for subsequent processing. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] The following is in conjunction with the appendix Figure 1-3 This embodiment describes a scrap removal and recycling device for coal gangue sintered bricks, comprising: a recycling cylinder 1, a feed inlet 2 on the top wall of the recycling cylinder 1, a grinding shaft 3 rotatably connected inside the top wall of the recycling cylinder 1, the grinding shaft 3 being connected to a grinding rotating tool 4, a positioning ring 5 concentrically provided on the outside of the grinding rotating tool 4, multiple grinding discs 6 evenly distributed on the upper circumference of the positioning ring 5, the multiple grinding discs 6 forming an inner conical grinding surface, a bracket 7 provided at the lower part of the positioning ring 5, and the positioning ring 5, grinding discs 6, and bracket 7 being connected by bolts 8, a gap being left between the outer conical surface of the grinding rotating tool 4 and the inner conical surface of the grinding discs 6, the gap gradually decreasing in size from top to bottom.

[0021] In use, scraps and other raw materials are injected into the recycling cylinder 1 through the feed inlet 2. As the gap between the outer conical surface of the grinding wheel 4 and the grinding disc 6 gradually decreases from top to bottom, the raw materials enter the grinding gap. The power drives the grinding shaft 3 and the grinding wheel 4 to rotate. The grinding shaft 3, the grinding wheel 4 and the grinding disc 6 work together to grind the raw materials in the grinding gap and discharge them from the bottom. The lower part of the grinding disc 6 is supported by the bracket 7 to ensure that it is firmly fixed. When replacing the grinding disc 6, the bracket 7, which is no longer limited by the bolt 8, is removed by disassembling the bolt 8. The lower part of the grinding disc 6 loses its support and restriction and can rotate to a vertical position with the positioning ring 5 as the fulcrum. Then it can be lifted and removed without interfering with the conical grinding wheel 4. Therefore, the replacement can be completed without disassembling the whole thing.

[0022] The grinding shaft 3 and the grinding wheel 4 are hollow. The grinding shaft 3 and the grinding wheel 4 are rotatably connected to the stirring shaft 9. The stirring shaft 9 and the grinding shaft 3 are respectively connected to the power through different transmission mechanisms 10. The stirring shaft 9 rotates faster than the grinding shaft 3. The stirring shaft 9 is connected to the stirring blade 11.

[0023] The scraps and other raw materials enter the grinding gap together for grinding and discharge. After discharge, they fall and are mixed by the high-speed rotating stirring blades 11. The mixture is then discharged by the belt conveyor for subsequent processing. When disassembling the bracket 7, the stirring blades 11 must be disassembled first to avoid interference.

[0024] The grinding wheel 4 has a conical surface on its upper part.

[0025] The conical surface guides the material into the grinding gap.

[0026] The recycling cylinder 1 is fixed by the frame 12, and a belt conveyor 13 is provided at the bottom of the recycling cylinder 1.

[0027] The ground raw material falls onto belt conveyor 13 for easy transport to the next process.
