Honeycombed ceramic slurry water cooling vacuum refiner

Abstract

The invention provides a honeycombed ceramic slurry water cooling vacuum refiner, comprising a slurry feed cylinder, slurry stirring shafts with helical blades, a vacuum chamber, a pumping hole, two kneading rollers, a photoelectric control device, a transmission mechanism, a hollow extruding shaft with helical blades, a slurry discharge cylinder, a fence which has section area close to and slightly smaller than the slurry feed cylinder, a cooling water device, a frame, a speed reducer and a variable-frequency motor, wherein the front end of the slurry stirring shafts with helical blades is provided with a slurry scraping knife. The slurry feed cylinder consists of two cylinders which are communicated, the section plane of the slurry feed cylinder is in a shape of a lying 8, and is communicated in the middle; the outlet end of the slurry feed cylinder is provided with the fence and the pumping port to form primary vacuum area; one slurry stirring shaft with the helical blade extends into each single cylinder, and is supported by a bearing with a seal ring; a bearing at the front end of the slurry stirring shaft is provided with a plurality of slurry scraping knives consisting of crossed blades; the fence is arranged at the outlet of the slurry feed cylinder; the upper end of the vacuum chamber is provided with the pumping port to ensure the vacuum chamber and the slurry discharge cylinder to form a secondary vacuum area; the lower part of the vacuum chamber is provided with two kneading rollers which are engaged with each other; the slurry outlet on the front part of the slurry discharge cylinder is a cone with narrowing opening.

Description

technical field [0001] The invention relates to a water-cooled vacuum kneading machine for ceramic mud, especially honeycomb ceramic mud. Background technique [0002] Honeycomb ceramics is a kind of porous ceramics. Due to its high specific surface area and high porosity, it is widely used as a three-way catalyst carrier for automobile exhaust purification and as a regenerator for preheating and recovery of metallurgical industrial waste gas. The thermal stability, compressive strength and other physical and chemical properties of honeycomb ceramics affect its use function, and its physical and chemical properties are directly related to raw materials and processing technology. The kneading after kneading of honeycomb ceramic raw materials is an important part of the processing technology, that is, kneading under vacuum conditions can further improve the uniformity and compactness of each component. In order to eliminate the heat generated by mechanical stirring, it is nec...
