The scraper 42 is positioned horizontally and fixedly connected to the end surface of the fixed plate 41 facing away from the inner wall of the first collection chamber 34. Several leak holes 43 are formed in the scraper 42.

[0043] During the rotation of the first grinding roller 31 and the second grinding roller 32, the scraper 42 can scrape off the dust sticking to the grinding rollers and discharge it into the first collecting chamber 34 through the leakage hole 43. The setting of the leakage hole 43 can effectively prevent the accumulation of dust and avoid clogging.

[0044] Reference Figure 1 、 Figure 4 The grinding box 3 is provided with a discharge port on both the front and rear sides, and a movable door 36 is provided in the discharge port, and the movable door 36 is slidably penetrated into the wall thickness of the grinding box 3. Guide blocks 37 are provided on both sides of the movable door 36, and the guide blocks 37 are fixedly connected to the movable door 36. A guide chute 38 is provided in the side wall of the grinding box 3, and the inner wall of the guide chute 38 slides with the outer wall of the guide block 37. The operator opens the movable door 36 through the handle 361, and then the operator can collect and process the ash in the first collection chamber 34. The setting of the guide block 37 guides the movement of the movable door 36, and also prevents the movable door 36 from deflecting during the movement.

[0045] Reference Figure 1 、 Figure 5 The grinding box 3 has a discharge port on the side away from the fixed box 23. A circular frame 39 is disposed outside the discharge port. The circular frame 39 is vertically mounted and fixedly connected to the side wall of the grinding box 3. A closure assembly 7 is disposed within the circular frame 39.

[0046] The operator pulls the pull rod 72, and the movement of the pull rod 72 drives the closed door 71 to move, thereby opening the discharge port. The operator can collect and process the ash powder in the second collection chamber 35 through the discharge port.

[0047] The implementation principle of the pellet desulfurization ash crushing equipment of the embodiment of the present application is as follows: the operator first starts the rotating motor 12 and the driving motor 53, and then pours the pellets to be crushed into the crushing barrel 1 through the feed port 11. The rotating motor 12 drives the rotating shaft 13 and the spiral blade 14 to rotate, and performs the first crushing process on the pellets entering. After the first crushing, the pellets fall into the crushing box 2, and the driving motor 53 drives the driving gear 1 51 to rotate, and the driving gear 1 51 drives the driven gear 1 52 to rotate, thereby driving the first crushing roller 21 and the second crushing roller 22 to perform a secondary crushing process on them. The pellets after the second crushing fall into the grinding box 3 through the guide groove 24, and the driving motor 53 drives the pulley 1 61 to rotate, and the pulley 1 61 drives the driving gear 2 64 to rotate through the pulley 2 62 and the belt 63, and the driving gear 2 64 drives the driven gear 2 65 to rotate, thereby driving the first grinding roller 31 and the second grinding roller 32 to rotate and grind the pellets that have fallen into the crushing. When the first and second grinding rollers 31 and 32 are grinding, particles may adhere to the surfaces of the grinding rollers. These particles are scraped off by the scraper 42. The scraped particles fall through the holes 43 in the scraper 42 into the first collection chamber 34. The operator can then pull the movable door 36 to open the discharge port and collect the dust in the first collection chamber 34.

[0048] When it is necessary to collect the ground ash, the operator pulls the pull rod 72, and the movement of the pull rod 72 drives the closed door 71 to move. Then the operator collects and processes the ash in the second collection chamber 35 through the discharge port. When the collection is completed, the pull rod 72 is pushed downward, and the movement of the pull rod 72 drives the closed door 71 to move downward, closing the discharge port.
