Kneading machine

Abstract

A kneading machine, comprising a kneading chamber formed in the axial direction, an air inlet and an air outlet connected to the kneading chamber, an axially arranged paddle in the kneading chamber, a power supply and a drive motor, the paddle is a Z-shaped paddle One end of the paddle shaft of the Z paddle is connected to a servo motor installed on the outside of the kneader body, and the servo motor is connected to an external PC or PLC control cabinet; the air outlet connected to the kneading chamber and the setting The induced draft fan outside the kneader body is connected through the induced air pipe; the input end of the induced draft fan is connected with an external PC or PLC control cabinet; it has the advantages of simple structure, convenient operation, energy saving and environmental protection, and can Reduce the burden of manpower, can improve product kneading quality and product stability and other characteristics.

Description

technical field [0001] The invention relates to a kneader, which belongs to the field of chemical machinery equipment. Background technique [0002] The kneader plays a very important role in the production of chemical products. Usually the main part includes a pair of paddles that cooperate with each other and rotate. The semi-dry state or rubbery sticky Thick plastic materials are mixed evenly, and the materials react quickly to obtain uniform mixing and stirring. The kneader is suitable for mixing, kneading, crushing, dispersing, and polymerizing elastic-plastic materials. It has the advantages of uniform mixing, no dead angle, and high kneading efficiency. [0003] A traditional kneader includes a body and a variable-speed motor. The body is specifically a closed reaction kettle, and the reaction kettle is provided with a material inlet and a material outlet, and is provided with corresponding ventilation channels. The variable speed motor is shifted through the gearbo...

AI Technical Summary

Problems solved by technology

However, in the low-speed operation state, the motor current is close to full load, especially in summer, it is easy to cause the motor to heat up too high and damage the coil insulation layer, which affects the life of the motor; at the same time, the mechanical adjustment of the speed through the gearbox also brings waste of electric energy produced by the enterprise.
