Tilting type continuous acrylic cracking furnace

Abstract

The invention provides a tilting type continuous acrylic cracking furnace which is characterized in that a tilting type platform is arranged on the upper end surface of a base; a furnace body is arranged on the tilting type platform; a drum is arranged in the furnace body and supporting shafts at two ends of the drum are supported on supporting frames at two outer ends of the furnace body through roller wheels; a driving chain wheel I is arranged on an output shaft of a driving motor I and drives a driven chain wheel I arranged on a supporting shaft at one end of the drum through a chain I; a driving chain wheel II is arranged on an output shaft of a driving motor II; a driven chain wheel II is arranged at one end of a water-cooling type spiral feeding device; the driving chain wheel II drives a driven chain wheel II through a chain II; the lower end of a feeding hopper is hermetically communicated with one end of the water-cooling type spiral feeding device; the other end of the water-cooling spiral feeding device is dynamically sealed with the supporting shafts of the drum and is communicated with the inlet end of the drum; the outlet end of the drum is communicated with the inlet end of a primary condensation device; the outlet end of the primary condensation device is communicated with the inlet end of a secondary condensation device; a liquid outlet of the secondary condensation device is communicated with a container tank. According to the tilting type continuous acrylic cracking furnace, continuous feeding and continuous heating cracking can be achieved, residual gas is fully condensed and residues on the inner wall of the drum can be easily removed. The tilting type continuous acrylic cracking furnace has relatively high practical values.

Description

technical field [0001] The invention belongs to the technical field of acrylic cracking regeneration equipment, and in particular relates to a tilting continuous acrylic cracking furnace. Background technique [0002] Acrylic is widely used in various industries, and using waste acrylic cracking and regeneration to obtain methyl methacrylate monomer to realize the recycling of acrylic is in line with the policy of circular economy and has good economic and social benefits. a faster development. The existing cracking equipment is intermittent cracking. The waste acrylic is directly put into the cracking tank heated by an open flame for cracking. The material is piled up in the tank and contacts the wall of the cracking tank. Due to uneven heating, the cracking temperature cannot be accurately controlled, and the quality of the finished product is poor. The recovery rate is low, the waste is large, the pyrolysis kettle is easy to scale and coke, and the lid of the pyrolysis k...

AI Technical Summary

Problems solved by technology

The existing cracking equipment is intermittent cracking. The waste acrylic is directly put into the cracking tank heated by an open flame for cracking. The material is piled up in the tank and contacts the wall of the cracking tank. Due to uneven heating, the cracking temperature cannot be accurately controlled, and the quality of the finished product is poor. The recovery rate is low, the waste is large, the pyrolysis kettle is easy to scale and coke, and the lid of the pyrolysis kettle needs to be opened when cleaning, and the coke is manually shoveled, which is difficult to clean and labor-intensive, and the cracking kettle is easy to be damaged by manual coke cleaning, and remains in the kettle during coke cleaning The emission of exhaust gas can easily cause environmental pollution and the disorderly diffusion of flammable and explosive gases, posing serious safety hazards

In addition, due to intermittent production, labor efficiency is low, and cracking a certain amount of waste and old organic glass often requires many cracking kettles, which occupy a large area and are inefficient. Therefore, it is necessary to propose an improvement
