The main control box 7 is placed in the area between the air outlet duct 61 and the operating pipe 62. The suction pipe 81 passes through the area between the main control box 7 and the air outlet duct 61. The air outlet duct is the discharge structure of the clean air of the purification mechanism. The design of the operating pipe can clean the filter plate and dust. The air outlet duct and the operating pipe are both extended outward, which can facilitate workers to directly operate on the side of the carriage. The layout design of the main control box and the suction pipe can realize the integrated design of various equipment, with reasonable layout and compact structure.

[0032] like Figure 3 and Figure 4As shown, a partition 66 is provided at the bottom of the purification box 63, and the area below the partition 66 is a first guide chamber 631, which is arranged opposite to the operation pipe 62, and the side of the first guide chamber 631 is connected to the discharge pipe 93, and a filter assembly 65 is installed inside the first guide chamber 631, and the filter part of the filter assembly 65 is arranged opposite to the outlet of the discharge pipe 93, and a guide port 661 is opened inside the partition 66, and the guide port 661 is located at the top of the outlet of the filter assembly 65, and a filter assembly 65 is provided above the partition 66.

[0033] As an improvement of the above technical solution, the filter assembly 65 includes a filter plate 651 and a sealing block 652. The sealing block 652 is slidably embedded in the operating tube 62. The filter plates 651 are arranged in multiple intervals. The end faces of each filter plate 651 are vertically fixed to the sealing block 652. The filter plates 651 are all facing the storage box 4. During filtering, the sealing block blocks the operating tube to ensure the stable flow of gas. When cleaning is required, pulling the sealing block outward will drive each filter plate to move outward synchronously, and workers can clean the filter plates.

[0034] like Figure 5 and Figure 6 As shown, a dust suction plate 82 is provided at the top of the extruder 8, and the dust suction plate 82 is provided at the top corner of the extruder 8. The outlet of the suction pipe 81 extends into the top of the extruder 8, and the outlet of the suction pipe 81 is directly opposite to the inner side of the dust suction plate 82. The inner wall of the dust suction plate 82 is evenly provided with suction holes, and the main flow pipe 91 is connected with the dust suction plate 82; the suction pipe discharges the material directly onto the dust suction plate, and the suction pipe and the dust suction plate are both placed on top and arranged relatively, so that when the material is just discharged, the dust particles carried therein can be directly sucked away by negative pressure.

[0035] like Figure 6As shown, the dust suction plate 82 includes a vertical plate body 822 and a horizontal plate body 821, and the vertical plate body 822 and the horizontal plate body 821 are vertically connected as a whole. The horizontal plate body 822 is horizontally arranged on the inner top surface of the extruder 8, and the vertical plate body 822 is arranged on the inner wall of the extruder 8. The inner wall of the vertical plate body 822 is an inclined downward structure; the vertical plate body and the horizontal plate body can completely block the discharged material, the horizontal plate body is enclosed from the top, and the vertical plate body is enclosed from the side, so that the material can only move downward, and at the same time, it also realizes two-way dust attraction from the top and the side, thereby improving the dust attraction efficiency; the vertical plate body is inclined and extends downward to one side of the suction pipe, so that the plastic fragments can move along the vertical plate body, thereby prolonging the plastic retention time and improving the attraction effect.

[0036] like Figure 7 As shown, the smoke suction assembly includes a suction hood 92, a lifting and adjusting assembly, a suction guide pipe 95, a horizontal tube body 96, a vertical tube body 97 and a filter cartridge 98; the middle of the bottom surface of the main guide pipe 91 is vertically connected with a suction guide pipe 95, the bottom end of the suction guide pipe 95 is connected to the horizontal tube body 96, the bottom surface of the horizontal tube body 96 is vertically connected to a plurality of vertical tube bodies 97, the bottom surface of each vertical tube body 97 is vertically connected to the suction hood 92, the suction hood 92 is attached to the top surface of the cooling water tank 10, and a filter cartridge 98 is installed inside each vertical tube body 97 , lifting and adjusting components 94 are vertically provided on both sides of the bottom surface of the main guide pipe 91, and the bottom end of the lifting and adjusting component 94 is connected to the horizontal tube body 96, and the lifting and adjusting component 94 is used to drive the suction hood 92 to move up and down; harmful gases can be gathered through the suction hood, and then the vertical tube body, filter cylinder, horizontal tube body, suction guide pipe, main guide pipe, and discharge pipe; the suction hood is attached to the cooling water tank, which can achieve comprehensive suction without air leakage. At the same time, the lifting and adjusting component can drive the suction hood to move upward, which is convenient for workers to replace the filter cylinder and observe the cooling water tank.

[0037] As an improvement of the above technical solution, the lifting and adjusting assembly 94 includes a screw tube 941 and a screw rod 942. The screw tube 941 is vertically arranged on the bottom surface of the main flow pipe 91. The screw rod 942 is spirally installed inside the screw tube 941. The bottom end of the screw rod 942 is rotatably connected to the horizontal tube body 96. When the screw rod is rotated, it can be screwed into the screw tube or screwed out, thereby driving the suction hood to move up and down.

[0038] As an improvement of the above technical solution, the suction guide pipe 95 includes an upper tube body 951, a hose 952 and a lower tube body 953. The upper tube body 951 is vertically connected to the main guide pipe 91, and the lower tube body 953 is vertically connected to the middle of the top surface of the horizontal tube body 96. The upper tube body 951 and the lower tube body 953 are connected through the hose 952; the hose is exemplarily a corrugated tube, which can meet the needs of telescopic connection.

[0039] like Fig. 9As shown, the bottom end of the filter cartridge 98 is mounted on the inner wall of the suction cover 92 by screws, and the outer side of the suction cover 92 is hinged with a rotatable opening and closing movable plate 921; the flip-open movable plate allows workers to directly disassemble and remove the filter cartridge without having to operate from an upward position.

[0040] When the present invention is implemented:

[0041] During operation, the exhaust fan 64 works, and the crushed plastic entering the top of the extruder 8 is output to the dust suction plate 82. The dust suction plate 82 sucks out the dust in the plastic under negative pressure, so that the dust enters the main guide pipe 91. At the same time, the harmful gas is sucked out by the negative pressure. The harmful gas flows along the suction cover 92, the filter cylinder 98, the cross tube body 96, the suction guide pipe 95, and the main guide pipe 91. The purified gas will also enter the main guide pipe 91. Finally, the air carries the dust through the discharge pipe 93 into the first guide chamber 631, and the filter plate 651 filters the dust. Finally, the purified air is directly discharged.
