Description

Technical Field

[0001] The utility model relates to the technical field of rubber internal mixers, and particularly relates to an odor removal device for a rubber internal mixer. Background Art

[0002] An internal mixer is short for a closed rubber mixing machine, also known as a kneading machine, mainly used for the plasticizing and mixing of rubber. An internal mixer is a machine that is provided with a pair of rotors with specific shapes and rotating relatively, and intermittently plasticizes and mixes polymer materials in a closed state with adjustable temperature and pressure. During the rubber processing process, a large amount of pungent odor will be generated by the plastic raw materials, and the odor will leak out through the discharge port of the internal mixer. The leaked pungent odor not only pollutes the environment, but also endangers the physical and mental health of the operators. At present, during the rubber and plastic mixing and processing process, an ordinary vacuum pumping device is usually used. However, during the pumping process, not only can the odor gas not be effectively disinfected, but also the carbon powder particles in the internal mixing chamber will be pumped, resulting in a waste of resources. For this reason, we have proposed an odor removal device for a rubber internal mixer. Content of the Utility Model
