Novel internal mixer for rubber production and rubber production process

Abstract

The invention provides a novel internal mixer for rubber production and a rubber production process. The novel internal mixer comprises a base, dust collection equipment, a conveying pipe, a telescopic inner pipe, a lifting dust collection cover, a material taking hopper, a left precipitation barrel, a right precipitation barrel, a precipitation box, a side dust collection cover and a discharging upper barrel; a supporting plate and an internal mixer main body are arranged on the upper surface of the base, and a main body of the dust collection equipment is fixedly connected to the upper portion of the internal mixer main body through bolts; the tail end of a pipe body of the conveying pipe is connected to an air inlet of the dust collection equipment in a welded mode, the tail end of the telescopic inner pipe is fixedly connected to the other end of the conveying pipe through welding, and the upper portion of the lifting dust collection cover is slidably connected to the outer side of the other end of the telescopic inner pipe through a telescopic outer pipe; and the upper end of a left precipitation barrel is fixedly connected to the left end of the conveying pipe through welding, and the upper end of the right precipitation barrel is fixedly connected to the right end of the conveying pipe through welding in the same way. Through the arrangement, the material waste is reduced, the dust collection efficiency is guaranteed, and the problem of environmental pollution is solved.

Description

technical field [0001] The invention belongs to the technical field of internal mixers, and more specifically relates to a novel internal mixer for rubber production and a rubber production process. Background technique [0002] The closed type rubber mixer is referred to as internal mixer, also known as kneader, which is mainly used for plasticizing and mixing of rubber. Internal mixer is a kind of machine with a pair of rotors with specific shape and relative rotation, which intermittently plasticizes and kneads polymer materials in a closed state with adjustable temperature and pressure. It is mainly composed of a mixing chamber, a rotor , rotor sealing device, feeding and pressing device, unloading device, transmission device and machine base, etc. When the internal mixer is working, the two rotors rotate relative to each other, and the materials from the feeding port are clamped and brought into the gap of the rollers and squeezed by the rotors. Pressing and shearing, ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a new type of internal mixer for rubber production and a rubber production process to solve the problem that when the internal mixer in the above patent is taking materials, a large amount of rubber powder is easy to float out from the feeding port, causing damage to the surrounding area. The environment will have a certain impact. When using vacuum equipment to purify the internal mixer, it is impossible to vacuum the side of the opening of the mixer's reclaiming chute, which will cause environmental pollution. In addition, if the vacuum is too strong, the solid rubber particles will be easily Suck away, creating a waste problem
