Different-direction double-screw pressing and exhausting device for continuous and efficient sulfur-breaking equipment

Abstract

The invention relates to a different-direction double-screw pressing and exhausting device for continuous and efficient sulfur-breaking equipment. The different-direction double-screw pressing and exhausting device comprises a motor, a machine barrel, double screws, a filter box, a pressure gauge, a safety valve, an outer hanging barrel, a ceramic heating ring and a sleeve, wherein the motor is used for driving the double screws to rotate; the double screws are arranged in the machine barrel; an inlet of the filter box is connected to an outlet of the machine barrel; an outlet of the filter box is connected to an inlet of the outer hanging barrel; the sleeve is arranged on the outer hanging barrel in a sleeving manner; an air layer is formed between the sleeve and the outer hanging barrel;the ceramic heating ring is arranged on the outer wall of the sleeve; an exhaust port is formed in the top of the outer hanging barrel and connected to an inlet of a waste water tank. Compared with asingle-screw structure, the double-screw structure is higher in conveying capacity and has a self-cleaning function, and the screw maintenance frequency is reduced. The production process is completed under a closed condition; liquid leakage and rubber powder scattering are avoided; and the phenomenon of material blockage in the filter box is avoided.

Description

technical field [0001] The invention relates to a counter-rotating twin-screw pressure exhaust device used for continuous and high-efficiency sulfur cutting equipment. It belongs to the technical field of reclaimed rubber production equipment. Background technique [0002] China is the world's largest tire producer. With the rapid development of my country's automobile industry, my country produced about 356 million waste tires in 2015, with a weight of 12.8 million tons, and will still grow at a rate of 6% per year. It is expected that by It will exceed 26 million tons in 2024. Waste rubber, waste tires and other waste rubber products are not easy to be landfilled and degraded. After burning, a large amount of smoke and carbon monoxide will seriously pollute the air, which will have a great negative impact on the natural environment, vegetation growth, human health and other aspects. It is an industrial hazardous waste. One of the most threatening garbage in the world. ...

AI Technical Summary

Problems solved by technology

[0003] The exhaust device is used on the extruder, which is one of the sulfur cutting equipment. Most of the existing exhaust devices have a single-screw structure, which has weak conveying capacity and is easy to block materials. At the same time, there is no self-cleaning function, which leads to high maintenance frequency of the screw.
