Embodiment 1

[0040] A polymer micro-negative pressure thermal cracking method for waste tires, the method includes the following steps:

[0041] 1) Put the block tire into the tank 1 of the crushing mechanism, and at the same time use the electric push rod 5 to drive the sealing plate 6 to close the bottom end of the tank 1, start the first rotating shaft 3, and crush the block tire to the particle size If the size is smaller than 40 mesh, then open the sealing plate 6, input the crushed tire particles into the bin body 4, start the first motor 8 to drive the second rotating shaft 9 to rotate, crush the material to a particle size smaller than 20 mesh, and then discharge it from the discharge port 10. Unload the material at any place;

[0042] 2) Inject the discharged materials from the embedded tube 14 of the reaction kettle into the kettle body 11, spread the materials flat on the microplate 19, and lift the embedded tube 14 so that the wide mouth 15 fits At the fixing ring 13, the air is pu...

Embodiment 2

[0049] A polymer micro-negative pressure thermal cracking method for waste tires, the method includes the following steps:

[0050] 1) Put the block tire into the tank 1 of the crushing mechanism, and at the same time use the electric push rod 5 to drive the sealing plate 6 to close the bottom end of the tank 1, start the first rotating shaft 3, and crush the block tire to the particle size If the size is smaller than 40 mesh, then open the sealing plate 6, input the crushed tire particles into the bin body 4, start the first motor 8 to drive the second rotating shaft 9 to rotate, crush the material to a particle size smaller than 20 mesh, and then discharge it from the discharge port 10. Unload the material at any place;

[0051] 2) Inject the discharged materials from the embedded tube 14 of the reaction kettle into the kettle body 11, spread the materials flat on the microplate 19, and lift the embedded tube 14 so that the wide mouth 15 fits At the fixing ring 13, the air is pu...

Abstract

The invention provides a high polymer micro negative pressure thermal cracking method for waste tires. Particularly, blocky tires are subjected to two-stage smashing directly, smashed materials are injected into a micro hole plate inside a kettle body through a pipe embedded into a reaction kettle, then, the kettle body is closed, at first, low speed temperature rise is performed under the micro negative pressure condition to reach about 120 DEG C for a period of time and the high temperature increase speed is adopted for increasing temperature to 450 DEG C under deep negative pressure condition, nitrogen protection is performed, continuous pyrolysis is performed under the pressure reduction condition, oil obtained after pyrolysis can be discharged downwards through the micro hole plate under the pressurizing condition, a solid phase remains on the micro hole plate, after drying and grinding are performed, and existing metal wires in tires exist in a granular or sheet shape, and can beremoved through screening. By applying the method, the whole process of smashing, pyrolyzing and collecting tires can be completed at a time, the metal wire stripping link is omitted, and the continuity and technological efficiency of the pyrolysis technology are obviously improved.

Description

Technical field [0001] The invention relates to the technical field of tire thermal cracking, in particular to a polymer micro-negative pressure thermal cracking method for waste tires. Background technique [0002] Waste tires have caused direct pollution to the environment, and countries around the world have devoted themselves to research on the recycling of waste tires. Compared with retreading, manufacturing rubber powder and reclaimed rubber, incineration and other waste tire treatment methods, pyrolysis method has the characteristics of large amount of waste tire treatment, high efficiency and low environmental pollution, and it is more in line with the recycling and harmlessness of waste treatment. Principles of transformation and reduction. In recent years, the pyrolysis treatment of waste tires has gradually developed from the laboratory stage to the large-scale stage. The pyrolysis research of waste tires has gradually shifted from the development of new processes and...
