[0040] As Figure 1 , Figure 2 and Figure 4 indicated, in the utility model, the bottom end of water storage tank 100 is provided with slag discharging device 300, slag discharging device 300 includes rotatingly connected slag collecting plate 310 at the bottom end of water storage tank 100, driving motor 320 for driving slag collecting plate 310 to rotate and spiral conveying assembly 330 located below slag collecting plate 310 and carrying out material slag transportation work.

[0041] As Figures 2-5As shown, specifically, the bottom of the water storage tank 100 is shaped like a downward-protruding funnel with an opening in the middle. The funnel-shaped design at the bottom of the water storage tank 100 facilitates the concentration of slag in the middle. The top of the slag collection plate 310 is provided with a protruding boss 311, which extends into the opening. A fixing rod 120 is fixed at the bottom of the water storage tank 100. A baffle 121 is provided at the bottom of the fixing rod 120. The bottom of the baffle 121 abuts against the top of the boss 311. The baffle 121 can clean the residual material residue on the surface of the boss 311 when the slag collection plate 310 rotates, preventing the material residue from accumulating. A spiral push plate 312 is provided at the top of the boss 311. The plate body of the spiral push plate 312 passes through the baffle 121. The spiral direction of the spiral push plate 312 from the inside out is the same as the rotation direction of the slag collection plate 310. The spiral push plate 312 and the rotation direction of the slag collection plate 310 are matched. Under the obstruction of the baffle 121, the material residue concentrated at the bottom of the water storage tank 100 can be pushed towards the center along the spiral trajectory, which is convenient for subsequent discharge.

[0042] like Figure 5 As shown, furthermore, the bottom end of the slag collecting plate 310 is provided with a protruding pipe 313, which is connected to the interior of the water storage tank 100.

A hopper 3311 is arranged at the top position of the bottom end of the conveying pipe body 331, which can guide the slag to smoothly enter the conveying pipe body 331, and a discharge port 3312 is arranged at the bottom position of the top end of the conveying pipe body 331. The output shaft end of the conveying motor 332 is coaxially connected with an auger 3321, the auger 3321 is sleeved on the inner side of the conveying pipe body 331, and the screw conveying assembly 330 drives the auger 3321 to rotate through the conveying motor 332, so that the slag falling through the protruding pipe 313 is conveyed upwards along the conveying pipe body 331 to the discharge port 3312 for discharge. The bottom end of the conveying pipe body 331 is connected with an emergency slag discharge pipe 3313, the end of the emergency slag discharge pipe 3313 is provided with a valve, and the emergency slag discharge pipe 3313 is used when the equipment fails or rapid slag discharge is required, thereby increasing the flexibility of slag discharge. A plurality of connecting rods 3315 are fixed between the conveying pipe body 331 and the water storage tank 100, the connecting rods 3315 ensure the stable connection between the conveying pipe body 331 and the water storage tank 100, and the stability of the conveying process is ensured.

[0045] It is worth noting that the driving motor 320 and the conveying motor 332 involved in the present application are both conventional technologies, and will not be described in detail in the present application.

[0046] In use of the wet grinding device with automatic slag removal of the present embodiment, firstly, during the process that the material after water washing and grinding is discharged through the discharge pipe 110, the residual fine slag is deposited at the bottom of the water storage tank 100; then, the driving motor 320 is started to drive the slag collecting plate 310 to rotate through the belt 340, at this time, the spiral push plate 312 on the boss 311 at the top end of the slag collecting plate 310 cooperates with the blocking brush 121 to push the slag at the bottom of the water storage tank 100 along a spiral trajectory to the center, and the blocking brush 121 can clean the residual slag on the surface of the boss 311; then, the slag pushed to the center falls into the hopper 3311 through the protruding pipe 313 and enters the bottom of the screw conveying assembly 330; finally, the conveying motor 332 is started to drive the auger 3321 to rotate, and under the action of the auger 3321, the slag is discharged from the discharge port 3312 along the conveying pipe body 331, and the whole automatic slag removal process is completed. Embodiment

[0047] In order to enhance the sealing property between the water storage tank 100 and the slag discharge device 300 and prevent liquid leakage, the following sealing measures are taken: specifically as shown in Figure 8 A sealing ring 3111 made of rubber material is embedded on the outer peripheral surface of the boss 311, the sealing ring 3111 can tightly fill the gap between the boss 311 and the water storage tank 100, and effectively prevent liquid from leaking out of the gap;

[0048] Meanwhile, a sealing ring 3131 made of rubber is embedded on the outer circumferential surface of the bottom of the convex tube 313, and when the convex tube 313 is inserted into the top of the hopper 3311, the sealing ring 3131 can tightly fit the gap between the convex tube 313 and the hopper 3311, further eliminating the possibility of liquid leakage, and ensuring the sealing and stability of the entire device during operation.
