Continuous double-helix asynchronous rubber powder plasticization device

Abstract

The invention belongs to the technical field of recovery processing of waste rubber, and relates to a continuous double-helix asynchronous rubber powder plasticization device. A helix cylinder is cut and closed by two cylinders along an outer wall to be connected to form an involutory 8-shaped double-cylinder structure, wherein a material inlet is fixedly formed in the upper side of one end of the structure, a material outlet is fixedly formed in the lower side of the other end of the structure, and bearings are respectively and fixedly arranged outside seal openings in two ends of the helix cylinder; helical blades are fixedly arranged on a threaded rod, a helix-shaped helix wing is coiled on the outer side face of the threaded rod, and two helical blade support type supports are arranged on the bearings; output power of a driving motor is respectively in butt joint with the corresponding helical blades; a control system measures and controls the rotation speed of the driving motor; a fuel spray nozzle in a fuel spray system penetrates through the outer wall of the helix cylinder of a first group of double-helix transport system; a first group of double-helix asynchronous transport system is provided with a heating system; the final group of double-helix asynchronous transport system is provided with a cooling system; the device is simple in structure, and convenient to operate, so that the automatic and continuous plasticization production of the rubber powder can be completely realized.

Description

Technical field: [0001] The invention belongs to the technical field of waste rubber recycling and processing, and relates to a double-helix asynchronous rubber powder continuous plasticizing device for continuously and automatically producing reclaimed rubber by using waste rubber powder. Background technique: [0002] As a strategic resource, rubber is a strategic resource. my country's annual average consumption accounts for 30% of the world's total consumption. More than 70% of my country's natural rubber and more than 40% of synthetic rubber need to be imported. The contradiction between supply and demand is very prominent. The impact of the shortage of rubber resources on the development of the national economy increasingly apparent. At the same time, the massive consumption of rubber will inevitably produce a large amount of waste rubber. In 2011, the weight of waste tires in my country exceeded 9 million tons. Using waste rubber to produce reclaimed rubber, partially...

Problems solved by technology

There are two existing technical solutions: one is the production process of dynamic desulfurization tank, and the other is the production process of normal pressure plasticization method. The traditional dynamic method of desulfurization tank production process is completed by placing rubber powder in a high-pressure tank under high temperature and high pressure conditions. The production of a can of reclaimed rubber has a process of mixing, charging, heating, cooling, and discharging. The waste of energy is serious. The electricity consumption per ton of reclaimed rubber is above 210 degrees. Due to the low level of intelligent automation of the equipment, the labor intensity Large, and there are potential safety hazards of tank aging and explosion; there is also a large amount of waste water and waste gas generated by the dynamic production process. At present, there are 30,000 sets of dynamic production equipment in operation in China, and the annual discharge of 18 million tons of waste water and 1.8 million tons of waste gas

Therefore, the traditional dynamic reclaimed rubber production process has been listed as an obsolete process by the country and the industry; the atmospheric pressure plasticization production process that has just emerged, although it has achieved continuous desulfurization of reclaimed rubber production, has obvious advantages, but because of rubber powder mixed with tar Certain viscosity, coupled with high temperature, the equipment used has the problem of sticking and blocking, and maintenance is extremely troublesome
