A cleaning tank 102 is arranged next to the frame 1.
[0053] Reference Figure 4 and Figure 5 The bottom open end of the cover 101 is close to the liquid surface of the cleaning pool 102, a processing tank 103 is bolted to the frame 1, and the processing tank 103 is filled with an adsorbent 104. An air pipe 105 is connected between the top of the cover 101 and the processing tank 103, and the end of the air pipe 105 in the processing tank 103 is deep in the adsorbent 104. An air pump 106 electrically connected to the control system is bolted to the frame 1, and an exhaust pipe 107 is connected between the air pump 106 and the processing tank 103.
[0054] Reference Figure 4 and Figure 5 A tilted conveyor belt 16 is rotatably arranged on the cleaning tank 102, the lower end of the conveyor belt 16 is located below the output end of the extruder 3, and the higher end of the conveyor belt 16 extends to the outside of the cleaning tank 102. Rollers 17 are rotatably arranged at both ends of the conveyor belt 16. A transmission motor 18 electrically connected to the control system is bolted to the cleaning tank 102, and the roller 17 at the higher end is coaxially welded to the output shaft of the transmission motor 18.
[0055] Reference Figure 4 and Figure 5A plurality of dehydration rollers 19 are rotatably connected to the frame 1, and the plurality of dehydration rollers 19 are arranged along the length direction of the frame 1. A dehydration mesh belt 20 is wound around the plurality of dehydration rollers 19, and the dehydration mesh belt 20 is located below the higher end of the conveyor mesh belt 16. The dehydration mesh belt 20 and the conveyor mesh belt 16 can adopt the wire mesh conveyor belt in the prior art. A dehydration motor 21 electrically connected to the control system is bolted to the frame 1, and one of the dehydration rollers 19 is coaxially welded to the output shaft of the dehydration motor 21. A dryer 22 electrically connected to the control system is bolted to the frame 1 and located above the dehydration mesh belt 20.
[0056] The control system starts the pelletizing motor 15, and the output shaft of the pelletizing motor 15 drives the blade 14 to rotate, thereby cutting the material extruded from the output end of the extruder 3 into particles, and the material particles fall on the conveyor belt 16 in the cleaning tank 102. The control system starts the transmission motor 18 and the dehydration motor 21, and the material particles are transported from the conveyor belt 16 to the dehydration belt 20, and the moisture is dried by the dryer 22.
[0057] At the same time, the control system starts the air pump 106, which extracts the air in the treatment tank 103 through the exhaust pipe 107, thereby forming a negative pressure in the treatment tank 103. The air in the cover 101 flows into the treatment tank 103 through the air supply pipe 105 and is adsorbed and processed by the adsorbent 104 in the treatment tank 103, thereby reducing the diffusion of harmful gases.
[0058] The implementation principle of Example 1 is: the control system opens the gate valve 8 on the feeding pipe 6, and then the automatic weighing feeder 2 accurately weighs a certain amount of polyolefin materials, cross-linking agents, stabilizers, additives and other raw materials and injects them into the feeding pipe 6, and then the control system closes the gate valve 8 and starts the heater 5, and then the control system starts the drive motor 93, and the output shaft of the drive motor 93 drives the inner shaft 91 to rotate.
[0059] At the same time, the transmission component 11 controls the rotation direction of the middle tube shaft 94 and the outer tube shaft 95, so that the primary spiral blade 96, the secondary spiral blade 97 and the tertiary spiral blade 98 in the cross-linking cylinder 4 are at different speeds and rotation directions, so that the raw materials in the cross-linking cylinder 4 are in a continuous mixing, stirring and heating state. During the repeated mixing and stirring of the raw materials in the cross-linking cylinder 4, a cross-linking reaction continuously occurs.
[0060] The inner shaft 91 drives the second bevel gear 112 to rotate through the first bevel gear 111 and the third bevel gear 113, and the second bevel gear 112 drives the middle tube shaft 94 to rotate, so that the secondary spiral blade 97 rotates in the opposite direction to the primary spiral blade 96, and the middle tube shaft 94 drives the fourth bevel gear 114 to rotate synchronously, and the fourth bevel gear 114 drives the fifth bevel gear 115 to rotate through the sixth bevel gear 116, and the fifth bevel gear 115 drives the outer tube shaft 95 to rotate, so that the tertiary spiral blade 98 rotates in the opposite direction to the secondary spiral blade 97, so that the raw materials in the cross-linking cylinder 4 are in a continuous mixing and stirring state.
[0061] After the raw materials in the cross-linking cylinder 4 are mixed and stirred for a period of time, the control system starts the second cylinder 131, and the piston rod of the second cylinder 131 drives the sixth bevel gear 116 to separate from the fourth bevel gear 114 and the fifth bevel gear 115 through the second reversing rod 132. During this process, the second reversing rod 132 gradually separates from the second driving cone 137, and the second compression spring 138 recovers its deformation.
[0062] The second transmission cone column 133 is inserted into the second cone groove 134 on the outer tube shaft 95, so that the middle tube shaft 94 and the outer tube shaft 95 rotate synchronously and in the same direction, and the cross-linked product in the cross-linking cylinder 4 is transported to the primary spiral blade 96. Since the inner shaft 91 and the middle tube shaft 94 rotate in opposite directions at this time, the material in the cross-linking cylinder 4 continues to be stirred and mixed.
[0063] The control system starts the first cylinder 121, and the piston rod of the first cylinder 121 drives the third bevel gear 113 to separate from the first bevel gear 111 and the second bevel gear 112 through the first reversing rod 122. During this process, the first reversing rod 122 gradually separates from the first driving cone 127, and the first compression spring 128 restores its deformation. The first transmission cone column 123 is inserted into the first cone groove 124 on the middle tube shaft 94, so that the inner shaft 91 and the middle tube shaft 94 rotate synchronously and in the same direction, and then the control system controls the drive motor 93 to rotate in the opposite direction, and the cross-linked product in the cross-linking cylinder 4 is transported to the discharge pipe 7 and then transported to the extruder 3 through the discharge pipe 7.
[0064] The control system starts the pelletizing motor 15, and the output shaft of the pelletizing motor 15 drives the blade 14 to rotate, thereby cutting the material extruded from the output end of the extruder 3 into particles, and the material particles fall on the conveyor belt 16 in the cleaning tank 102. The control system starts the transmission motor 18 and the dehydration motor 21, and the material particles are transported from the conveyor belt 16 to the dehydration belt 20, and the moisture is dried by the dryer 22.
[0065] At the same time, the control system starts the air pump 106, which extracts the air in the treatment tank 103 through the exhaust pipe 107, thereby forming a negative pressure in the treatment tank 103. The air in the cover 101 flows into the treatment tank 103 through the air supply pipe 105 and is adsorbed and processed by the adsorbent 104 in the treatment tank 103, thereby reducing the diffusion of harmful gases.
