Description

Technical Field

[0001] The utility model relates to the technical field of internal mixer design, in particular to an internal mixer for rubber production with a cooling device. Background Art

[0002] An internal mixer is a machine equipped with a pair of rotors of a specific shape that rotate relative to each other, and intermittently plasticizes and mixes polymer materials in a closed state with adjustable temperature and pressure. During the plasticizing and mixing process of the rubber in the internal mixer, the rotor in the sealed chamber continuously squeezes and shears the polymer material, causing the rubber to generate a large amount of heat and then burn, which in turn causes the temperature of the sealed chamber to rise. Therefore, it needs to be cooled by a cooling device. However, the commonly used cooling method is a single air-cooling to dissipate heat to the water-cooling device, which is prone to uneven heat dissipation. The single air-cooling heat dissipation is easily affected by the external environment, and the single water-cooling device is difficult to continuously cool it, resulting in poor cooling effect, affecting the heat dissipation efficiency of the internal mixer, and thus affecting the operating efficiency of the internal mixer. To this end, an internal mixer for rubber production with a cooling device is proposed. Utility Model Content

The internal mixer 5 is set as a cylindrical working chamber. A water cooling device is set on the panel of the internal mixer 5 to quickly take away the heat conducted on the wall panel of the internal mixer 5, and the plastic inside the internal mixer 5 is cooled. A cooling seat 11 is set at the outer end of the internal mixer 5 to achieve auxiliary cooling treatment of the external space of the internal mixer 5. The purpose of quickly reducing the temperature of the mixed plastic product in the internal mixer 5 is achieved through the mutually auxiliary air cooling device and water cooling device, reducing the negative impact of high temperature on the internal mixer components, and extending the service life of the internal mixer components.

[0027] The water-cooling assembly is attached to the outer wall of the internal mixer 5 and can reduce the temperature of the plastic product in the internal mixer 5 through the flow of cold water.
