Sealing pyrolyzing furnace achieving continuous feeding and discharging

Abstract

The invention relates to a sealing pyrolyzing furnace achieving continuous feeding and discharging. The furnace comprises a screw feeder, a feeding bin, a pyrolyzing furnace cylinder, a discharging bin and a screw discharge bin which are sequentially connected in the material conveying direction, the feeding bin and the discharge bin are fixedly arranged on a rack, the pyrolyzing furnace cylinderis supported on the upper portion of the rack through multiple rollers, the outer wall of the pyrolyzing furnace cylinder is sleeved with a gear ring, the rack is provided with a driving mechanism driving the pyrolyzing furnace cylinder to rotate along the central axis through the gear ring, one end of the pyrolyzing furnace is communicated with the feeding bin, the other end of the pyrolyzing furnace is communicated with the discharge bin, a heating pyrolyzing mechanism is arranged in the middle of the pyrolyzing furnace and comprises a combustion chamber located on the lower portion and a pyrolyzing chamber located on the upper portion, openings allowing the pyrolyzing furnace to penetrate through are formed in the left side and the right side of the pyrolyzing chamber, and elastic sealing structures preventing air leakage are arranged on the joints of the pyrolyzing furnace cylinder and the feeding bin, the discharge bin and the pyrolyzing chamber. The sealing pyrolyzing furnace hasthe advantages that the structure is reasonable, continuous feeding and discharging can be achieved, the sealing effect is good, the safety is good, and the pyrolyzing efficiency is high.

Description

technical field [0001] The invention belongs to the field of pyrolysis recycling of wastes rich in organic matter, and in particular relates to a sealed pyrolysis furnace for continuously feeding and discharging materials. Background technique [0002] Wastes rich in organic matter mainly include organic sludge and waste plastics (including circuit boards, plastic packaging materials, etc.). On the one hand, these organic wastes accumulate space and pollute the environment, requiring urgent treatment. On the other hand, they contain a large amount of organic matter. After pyrolysis, pyrolytic charcoal, gas, and fuel oil with high added value can be obtained. [0003] Existing organic waste pyrolysis furnaces and corresponding pyrolysis methods usually have the following deficiencies: 1) The material cannot be continuously fed in and out. Usually, after the feeding of a furnace is completed, it is sealed and then pyrolyzed. After the material is discharged, it is repeated. S...

Problems solved by technology

[0003] Existing organic waste pyrolysis furnaces and corresponding pyrolysis methods usually have the following deficiencies: 1) The material cannot be continuously fed in and out. Usually, after the feeding of a furnace is completed, it is sealed and then pyrolyzed. After the material is discharged, it is repeated. Specifically, a kind of garbage carbonization pyrolysis furnace disclosed in CN 201505660 has the disadvantages of feeding and discharging at intervals, poor continuity, high labor intensity and low pyrolysis efficiency; 2) it can realize continuous feeding and discharging to a certain extent, but In terms of structural design, there are still low thermal efficiency (the heating plate heats the material on the endless belt), poor stability of feeding and discharging materials (the double-layer slide valve controls the feeding and discharging materials), poor sealing effect, and materials during pyrolysis in the furnace Conveyor equipment (ring belt) is damaged quickly by heat, resulting in high cost and many other shortcomings
