Description

Technical Field

[0002] Solid hazardous waste refers to solid hazardous materials with explosive, flammable, corrosive, toxic or other harmful properties generated during the production, operation, use and management process. It includes injection molded parts. Injection molded parts refer to various injection molded products produced by injection molding machines, collectively known as injection molded parts, including various packaging, parts, etc., which are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. There are wastes in the processing of injection molded parts, and most of the wastes are processed by crushing.

[0003] When using existing solid hazardous waste pretreatment equipment, the waste is usually added directly into the crushing box for crushing. However, adding too much at one time can easily affect the crushing effect, and it can also cause incomplete crushing, affecting subsequent melting operations.

[0049] Specifically, L-shaped clamping plates 71 are fixedly installed on the left and right sides of the heating box 7 near the front side, and clamping bolts 72 are threaded through the L-shaped clamping plates 71. The output ends of the clamping bolts 72 are threadedly inserted into the outer wall of the outer side of the sealing plate 9, thereby serving to disassemble and assemble the sealing plate 9.

[0050] Working principle: When in use, the waste to be processed can be added to the feeding hopper 3. After the addition is completed, the servo motor A42 and the drive motor 40 can be operated. When the servo motor A42 is running, it will drive the turntable 43 to rotate. When the turntable 43 rotates, it will drive the sliding frame 45 to move up and down back and forth through the fixed shaft 44. When the sliding frame 45 moves up and down, it will drive the crushing plate 47 to move up and down back and forth in the feeding hopper 3 through the L-shaped plate 46, which can play a role in pre-processing the waste. In addition, when the servo motor A42 is running, it will also drive the rotating rod 511 to rotate through the synchronous belt 512. When the rotating rod 511 rotates, it will drive the reciprocating screw 51 to rotate. When the reciprocating screw 51 rotates, it will drive the screw nut 52 to move back and forth. When the movable rack plate 55 moves, the adjacent movable gear 56 is driven to rotate. When the movable gear 56 rotates, the adjacent threaded rod 57 is driven to rotate. When the threaded rod 57 rotates, the adjacent threaded sleeve 58 is driven to move back and forth relative to or oppositely. When the threaded sleeve 58 moves relative to or oppositely, the trapezoidal opening and closing blocks 59 on both sides are driven to move back and forth relative to or oppositely through the fixed rod 591, which is conducive to the indirect discharge of the pre-treated waste. After discharge, the waste will fall between the crushing rollers 20, and when the drive motor 40 is running, it will drive the front and rear crushing rollers 20 to rotate in the opposite direction under the transmission of the rotating gear 30. , the fallen waste can be crushed. In addition, when the L-shaped plate 46 moves up and down, it will also drive the pressing plate 62 to move up and down through the L-shaped rod 61. When the pressing plate 62 moves down a distance, it will contact the squeezing plate 63. At this time, it will squeeze the squeezing plate 63 to move downward. When the squeezing plate 63 moves downward, it will drive the movable plate 64 to move downward, and at the same time, it will stretch the return springs A642 on both sides. When the movable plate 64 moves downward, it will drive the lifting rack plate 65 to move downward. When the lifting rack plate 65 moves downward, it will drive the rotating gear 67 on the right to rotate. Since the two rotating gears 67 are meshed, they will drive the rotating gears 67 on both sides to move in the opposite direction. When the rotating gear 67 rotates, it will drive the adjacent transmission shaft to rotate, and when the transmission shaft rotates, it will drive the corresponding The adjacent dispersion plate 66 swings upward, which can realize the dispersion and dropping of the discharged waste. When the L-shaped plate 46 moves upward, the movable plate 64 will be restored under the action of the rebound force of the adjacent reset spring A642, so it will drive the dispersion plate 66 to swing back and forth to restore, which is conducive to the dispersion of the discharged waste. The waste crushed by the crushing roller 20 will fall into the screening frame 10, and the setting of the reset spring B93 can make the screening frame 10 shake up and down when it is subjected to the weight of the waste, which is conducive to improving the screening efficiency. The waste after screening will fall onto the electric heating wire mesh to melt, so that it is discharged and dripped through the discharge pipe. After screening is completed, the screening frame 10 can be taken out, which is conducive to the removal of the larger waste and can be re-added for crushing.By rotating the clamping bolts 72 on both sides to make it away from the outside of the heating box 7, the clamping of the sealing plate 9 can be released, and then the sealing plate 9 can be stretched to drive the screening frame 10 to move forward, which is convenient for taking out the screening frame 10. When the staff is inconvenient to disassemble, the servo motor B81 can be operated. When the servo motor B81 is running, it will drive the transmission bevel gear 82 to rotate. When the transmission bevel gear 82 rotates, it will drive the transmission rod 84 to rotate through the driven bevel gear 83. When the transmission rod 84 rotates, it will drive the adjacent transmission gear 86 to rotate through the chains 85 on both sides. When the transmission gear 86 rotates, it will drive the adjacent transmission rack plate 87 to move forward. When the transmission rack plate 87 moves forward, it will drive the sealing plate 9 upward through the adjacent cross bar 88, so that the screening frame 10 can be taken out. The opposite operation can restore the screening frame 10.
