Banburying mixer for producing PVC sheets through waste PVC

Abstract

The invention discloses a banburying mixer for producing PVC sheets through waste PVC. The banburying mixer comprises a base, a banburying chamber, a first protection hood and a second protection hood, wherein a material collecting chamber is formed in one side in the base, and a water collecting chamber is also formed in the base; sewage holes which communicate with the water collecting chamber are formed in the top plate of the base; the banburying chamber is formed above the base, and communicates with the material collecting chamber; a through hole is horizontally formed in one side wall of the banburying chamber, and an end plate is movably arranged on the other opposite inner wall of the banburying chamber; a sealing plate is movably arranged in the through hole; two rotors are symmetrically arranged on the inner side of the sealing plate; the tail ends of the two rotors are movably connected with the end plate; one side adjacent to the through hole in the banburying chamber, ofthe first protection hood is arranged on the top surface of the base; a driving mechanism for driving the rotors to rotate is arranged in the first protection hood; and a sliding mechanism for drawingthe rotors out is arranged in the first protection hood. Through the adoption of the banburying mixer disclosed by the invention, the rotors are convenient to clean in an omnidirectional manner, andthe cleaning effect is good; and cleaning is performed in a closed environment, so that the situation that impurities cannot enter the inner part of the equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of PVC processing, in particular to an internal mixer for producing PVC sheets by using waste PVC. Background technique [0002] At present, the closed rubber refining machine is called internal mixer for short, 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 and other parts. [0003] The Chinese patent application number is 201120493410.6, which is a closed type PVC internal mixer, including a pressing device beam, a cylinder, a stand, a rotor, an inner tank, a fixed seat, a coupling and a drive m...

AI Technical Summary

Problems solved by technology

Although this solution solves the problem of low production efficiency in the existing technology, it can effectively improve production efficiency, but after a long time of use of the internal mixer, impurities will adhere to the rotor, which is inconvenient to clean, which will lead to a gradual decrease in equipment operation efficiency, which is not conducive to For normal production work, design a kind of internal mixer that utilizes waste PVC to produce PVC sheets to solve the above problems
