Through the combined action of the bracket 12, the collection box 27, the discharge port 14 and the sealing plate 17, the collection box 27 can be taken out by using the sealing plate 17 to close the bracket 12 to pour out solid impurities, effectively isolating air from entering the device and avoiding affecting the continuous operation of the device.

[0030] Specifically, legs 2 are fixedly connected to the four corners of the bottom of the box body 1. An inclined platform 21 is fixedly connected to the bottom of the inner wall of the box body 1. Feeding bins 26 are communicated with one side of the tops of the left shell 4 and the right shell 5. An observation window 24 and a controller 25 are arranged on the front surface of the box body 1.

[0034] The working principle of the present utility model is as follows: When in use, the device is connected to an external power supply. The second electric push rod 9 below the right shell 5 contracts, driving the movable plate 10 to insert into the right shell 5 through the through groove 8 to complete the sealing of the right shell 5. Waste plastics are poured into the left shell 4. The first electric push rod 6 extends to push the piston block 7 to move. The piston block 7 pushes the waste plastics to move. The conical discharge end of the left shell 4 blocks most of the waste plastics from moving, and a small part enters the feeding pipe 3, making the waste plastics compacted between them to achieve a sealing effect. The waste plastics entering the feeding pipe 3 fall into the pyrolyzer body 11. The pyrolyzer body 11 works to thermally pyrolyze the waste plastics. The substances generated by thermal pyrolysis fall on the inclined hollow plate 13. The liquid passes through the inclined hollow plate 13 and falls to the bottom of the inner wall of the box body 1. The solid impurities slide into the collection box 27 under the action of gravity. When the feeding of waste plastics in the left shell 4 is completed, the first electric push rod 6 can drive the piston block 7 to move to one side of the through groove 8 below the left shell 4, so that the movable plate 10 below the left shell 4 closes the left shell 4. Repeat the above operation and use the right shell 5 for feeding, so as to alternately perform the feeding work in sequence;

[0035] Regularly clean the solid impurities in the collection box 27. During cleaning, the third electric push rod 18 contracts to drive the sealing plate 17 to move, so that one end of the sealing plate 17 abuts against one side of the bracket 12 to complete the sealing of the bracket 12. Then, the discharge port 14 can be unfolded to take out the collection box 27, pour out the collected solid impurities, and then put the collection box 27 back. The third electric push rod 18 extends to drive the sealing plate 17 to move outwards. During the process of dealing with the solid impurities in the collection box 27, the solid impurities that slide down onto the sealing plate 17 through the inclined hollow plate 13 are scraped off by the trapezoidal strip 19 and fall into the collection box 27, so as to make the device achieve the purpose of continuous operation and improve the working efficiency of the device.
