[0032] The above solution is adopted as follows: By setting up the dust suppression component 4, the material inside the jaw crusher 2 can be dusted during processing to prevent dust from escaping. By setting up the pump body 401 and the water pipe 402, the water source inside the water tank 5 can be extracted and input into the inner cavity of the water storage shell 403 through the water pipe 402. By setting up the water storage shell 403 and the nozzle 404, the water flow inside the water storage shell 403 can be sprayed out through the nozzle 404 to suppress dust on the material inside the jaw crusher 2.

[0033] refer to Figure 2 , Figure 3 and Figure 4The scraping assembly 7 includes a scraper 701 and two connecting rods 702. The bottom of the scraper 701 contacts the filter plate 6. The two connecting rods 702 are located on the left and right sides behind the scraper 701, respectively, and are fixedly connected to the scraper 701.

[0035] refer to Figure 1 , Figure 2 and Figure 5 The striking assembly 8 includes a swing frame 801, two drive shafts 802, and two drive plates 803. Multiple striking heads 804 are evenly distributed on the top of the swing frame 801 and are fixedly connected to the striking heads 804. The side of the striking head 804 away from the swing frame 801 contacts the discharge hopper 3. The two drive shafts 802 are respectively located on the left and right sides of the swing frame 801 and are fixedly connected to the swing frame 801. The side of the two drive shafts 802 away from the swing frame 801 passes through the water tank 5 and extends to the outside of the water tank 5 and is fixedly connected to the drive plates 803. Torsion springs 805 are sleeved on the surface of the drive shafts 802. The left and right sides of the torsion springs 805 are fixedly connected to the outer surfaces of the drive plates 803 and the water tank 5, respectively.

[0036] The above solution is as follows: By setting the striking component 8, the discharge hopper 3 can be struck, which facilitates the discharge of material from the discharge hopper 3. By using the swing frame 801 and the striking head 804, the striking head 804 can be rotated during the rotation of the swing frame 801, so that the striking head 804 is no longer in contact with the bottom of the feed hopper. By setting the transmission plate 803 and the transmission shaft 802, the swing frame 801 can be rotated during the rotation of the transmission plate 803, and the torsion spring 805 can be torn. By setting the torsion spring 805, the rebound force released after torsion can drive the transmission plate 803 to rotate in the opposite direction, and drive the swing frame 801 to rotate in the opposite direction through the transmission shaft 802, which in turn drives the striking head 804 to rotate in the opposite direction and reset, thus striking and vibrating the bottom of the discharge hopper 3, which facilitates the discharge of material from the discharge hopper 3.

[0037] refer to Figure 2 and Figure 4 The drive device 9 includes a servo motor 901, a screw 902, and a moving plate 903.

The left and right sides of the rear side of the moving plate 903 are fixedly connected to the connecting rod 702.

[0038] The above scheme is adopted as follows: by setting the drive device 9, the scraping assembly 7 and the linkage assembly 10 can be driven; by setting the servo motor 901, the screw 902 can be driven to rotate; by setting the screw 902, the moving plate 903 can be driven to move; by setting the moving plate 903, the connecting rod 702 and the linkage rod 1001 can be driven to move synchronously.

[0039] refer to Figure 2 and Figure 5 The linkage component 10 includes a linkage rod 1001.

A pressing column 1002 is fixedly connected to the front side of the linkage rod 1001 away from the moving plate 903. A contact wheel 1003 is rotatably connected to the right side of the pressing column 1002.

[0040] The above solution is adopted as follows: by setting the linkage component 10, the striking component 8 can be driven. By setting the linkage rod 1001 and the pressing column 1002, the transmission plate 803 can be pressed by the pressing column 1002 during the movement of the linkage rod 1001. The pressing force generated at this time will push the transmission plate 803 to rotate. By setting the contact wheel 1003, the wear between the pressing column 1002 and the transmission plate 803 can be reduced.

[0041] refer to Figure 2 and Figure 4 Limiting components 14 are fixedly connected to the left and right sides of the rear side of water tank 5. The left and right sides of the moving plate 903 are sleeved on the surface of the limiting component 14 and are slidably connected to the limiting component 14 through linear bearings.

[0042] By adopting the above solution, the limiting component 14 can limit the movement of the movable plate 903, making it easier for the movable plate 903 to move.

[0043] The working principle of this utility model:

[0044] When crushing the raw materials of alumina-based fused materials, the raw materials are put into the inner cavity of jaw crusher 2. After being crushed by jaw crusher 2, the raw materials are discharged through discharge hopper 3.

[0045] During the crushing process, an external water source is connected to the inlet of water tank 5, and the water source enters the inner cavity of water tank 5. At the same time, pump body 401 and servo motor 901 are started. Pump body 401 will draw water out of the inner cavity of water tank 5 and input it into the inner cavity of water storage shell 403 through water pipe 402. Then, the water flow in the inner cavity of water storage shell 403 will be sprayed out through multiple nozzles 404 fixedly connected on its surface to spray water into the inner cavity of jaw crusher 2 and suppress dust generated during crushing.

[0046] During the dust suppression process, some of the wastewater generated will fall into the inner cavity of the water tank 5 through the leakage hole 13. Since the leakage hole 13 is smaller than the size of the crushed raw material, the raw material will be discharged normally. As the wastewater enters the water tank 5, it will be filtered by the filter plate 6 in the inner cavity of the water tank 5. The filtered water will be pumped out again by the pump body 401 and sprayed out again through the nozzle 404 to recycle the wastewater.

[0047] Simultaneously, when the servo motor 901 starts, it drives the screw 902 to rotate. During the rotation of the screw 902, it drives the moving plate 903 to move on the surface of the limiting member 14. The moving plate 903 drives the connecting rod 702 and the linkage rod 1001 to move synchronously. The connecting rod 702 drives the scraper 701 to move, scraping off the impurities attached to the surface of the filter plate 6 and discharging them through the rectangular hole 11. When the moving plate 903 reaches the appropriate position, the servo motor 901 is started to reverse, driving the moving plate 903 to move in the opposite direction. The moving plate 903 drives the scraper 701 to move in the opposite direction through the connecting rod 702, so that the scraper 701 cleans the surface of the filter plate 6 back and forth, making it convenient for the filter plate 6 to filter sewage in the future.

[0048] During its movement, the linkage 1001 drives the extrusion column 1002 to move synchronously. When the extrusion column 1002 moves to the appropriate position, its rotatably connected contact wheel 1003 contacts the transmission plate 803 and generates extrusion. The resulting extrusion force pushes the transmission plate 803 to rotate. During its rotation, the transmission plate 803 drives the swing frame 801 to rotate around the transmission shaft 802, and twists the torsion spring 805. During its rotation, the swing frame 801 drives the striking head 804 to rotate, so that the striking head 804 no longer contacts the discharge hopper 3. Meanwhile, during the reverse movement of the moving plate 903, the extrusion column 1002 will move in the reverse direction via the linkage rod 1001. The extrusion column 1002 will drive the contact wheel 1003 to move in the reverse direction, so that the contact wheel 1003 no longer extrudes the transmission plate 803. At this time, the rebound force released after the torsion spring 805 is twisted will drive the transmission plate 803 to rotate in the reverse direction. The transmission plate 803 will drive the swing frame 801 to rotate in the reverse direction via the transmission shaft 802. The swing frame 801 will drive the striking head 804 to rotate in the reverse direction and reset, so that the striking head 804 will strike the bottom of the discharge hopper 3, which will facilitate the discharge of material from the discharge hopper 3.

[0049] In summary, this crushing device for processing alumina-based fused materials, through the coordinated use of a dust suppression component 4, a water tank 5, a filter plate 6, a scraping component 7, a striking component 8, a drive device 9, and a linkage component 10, solves the problem that existing jaw crushers typically spray water into the inner cavity of the jaw crusher during processing to suppress dust and prevent dust from escaping. However, during the dust suppression process, most of them lack the function of recycling and filtering the generated wastewater, resulting in the wastewater not being effectively recycled and reused, leading to water resource waste.
