[0032] The noise reduction double-roller crushing pretreatment device 32 includes a crushing box 33, a sound-absorbing cotton interlayer 34 is provided in the middle of the outer surface of the four sides of the crushing box 33, a feed hopper 35 is fixedly connected to the middle of the outer surface of the upper end of the crushing box 33, and a lower hopper 36 is fixedly connected to the middle of the inner surface of the lower end of the crushing box 33. A No. 2 drive motor 37 is fixedly installed on the outer surface of one side of the crushing box 33, a rotating shaft 38 is provided at the other end of the output shaft of the No. 2 drive motor 37, and a No. 2 bearing seat 39 is provided between the other end of the rotating shaft 38 and the middle of the inner surface of the other side of the crushing box 33. A crushing roller 40 is fixedly installed on the outer ring of the rotating shaft 38, and a crushing channel 41 is formed between the crushing rollers 40.

[0035] How it works First, the No. 2 drive motor 37 is started. After the output shafts of the two groups of No. 2 drive motors 37 rotate in opposite directions, the rotating shaft 38 at the other end is driven to rotate in the crushing box 33 through the No. 2 bearing seat 39, thereby driving the two groups of crushing rollers 40 to rotate in opposite directions. A crushing channel 41 is formed between the rotations of the two groups of crushing rollers 40. The calcium carbonate raw material is put into the crushing box 33 through the feed hopper 35. The raw material falls between the crushing channels 41 through the feed hopper 35 and is pre-crushed by the two groups of crushing rollers 40 rotating in opposite directions. After the raw material is initially crushed into small pieces, it is pushed out by the piston rod of the electric cylinder 6, driving the U-shaped solid The fixed seat 7 slides in the guide chute 5 through the positioning slide block 8 until the discharge box 9 on the U-shaped fixed seat 7 moves to the right below the lower hopper 36. After the small pieces of raw materials pass through the lower hopper 36 and fall into the discharge box 9, the piston rod of the electric cylinder 6 is controlled to retract, driving the U-shaped fixed seat 7 at the other end to slide in the guide chute 5 through the positioning slide block 8 to the right below the movable grinding and crushing plate 31. After the piston rod of the hydraulic cylinder 20 is controlled to be pushed out, the U-shaped mounting seat 22 at the lower end is driven to slide on the guide slide rail 19 through the positioning sleeve 24, thereby driving the movable grinding and crushing plate 31 to be pressed down until the movable grinding and crushing plate 31 is pressed down into the discharge box 9, and the discharge box 9 is further crushed, and at the same time, the output shaft of the No. 1 driving motor 25 is controlled to rotate, driving the threaded screw 26 to rotate in the U-shaped mounting seat 22 through the No. 1 bearing seat 27. The movable nut seat 28 is driven by the meshing of the threaded screw 26 and the limiting action of the limiting slider 29 sliding on the limiting slide rail 23. The movable nut seat 28 can move linearly on the threaded screw 26, thereby driving the movable grinding and crushing plate 31 at the lower end of the reinforcing connecting arm 30 to move horizontally in the discharge box 9, thereby cooperating with the fixed grinding plate 10 to further crush the broken raw materials, thereby improving the overall crushing efficiency of the calcium carbonate raw materials. The surface is improved to improve the crushing effect. After the raw materials are crushed, the electric push rod 12 is controlled to retract, driving the anti-skid clamping block 14 at the other end to separate from the anti-skid pads 15 on both sides of the discharge box 9, and the discharge box 9 can be taken out from the U-shaped fixed seat 7 to facilitate the collection of the crushed raw materials. When installing the discharge box 9, the positioning embedded base 11 can be quickly positioned and fixed in the positioning embedded groove 42, and the anti-skid clamping block 14 is driven by the electric push rod 12 to move to the anti-skid pads 15 on both sides of the discharge box 9, and the discharge box 9 is clamped and fixed in the U-shaped fixed seat 7 by force, completing the rapid disassembly and assembly between the discharge box 9 and the U-shaped fixed seat 7.
