Environment-friendly internal mixer

Abstract

An environment-friendly internal mixer comprises a feeding area, a mixing area and a discharging area. The feeding area comprises an air cylinder, a piston, a feeding hopper and a filler box. The feeding hopper is connected with the filler box. The mixing area comprises a material pressing rod, an internal mixing chamber, rotors, a circulating pipe and an air purifying device. The air purifying device is an anion electrostatic adsorber. The anion electrostatic adsorber is connected with the internal mixing chamber through an air guide pipe. The discharging area comprises a discharging door lock locking device, a discharging port and a base. The environment-friendly internal mixer is convenient to use and reasonable in design, through the arrangement of the anion electrostatic adsorber, flying dust in the mixing area can be adsorbed easily, thus, materials are free of the dust when discharged, dust pollution is eliminated, environment protection is facilitated, and physical health of operators is guaranteed easily; and each rotor is provided with ten ridges, the materials are dispersed in the internal mixing chamber effectively, the kneading effect among the ridges is reinforced, and the rubber mixing quality and the rubber mixing efficiency are improved.

Description

technical field [0001] The invention relates to the field of material processing and molding, in particular to an environment-friendly internal mixer. Background technique [0002] The internal mixer is a mechanical device that intermittently masticates and kneads polymer materials in a closed state with adjustable temperature and pressure. The shear effect on the rubber material in the internal mixer is much greater than that in the open mixer, and the temperature of the rubber mixing is high, which makes the rubber mixing efficiency of the internal mixer much higher than that of the open mixer. The rotor of the internal mixer rotates relatively, and the added material is clamped and brought into the roll gap, squeezed and sheared by the rotor, and after passing through the roll gap, it touches the sharp edge of the lower top bolt and is divided into two parts, along the front and rear chamber walls and the The gap between the rotors returns to the top of the roller gap. ...

AI Technical Summary

Problems solved by technology

[0003] However, in the process of intense heating of the rubber material, the water molecules evaporate and bring out the powder particles, which will cause dust pollution in the working area and endanger the respiratory tract and lung health of the operator. The dust left in the mixing room will pollute the processing of later materials and affect its quality
