Powder modification tank

Abstract

The invention discloses a powder modification tank which comprises a tank body, a support, a powder spraying mechanism, a premixing mechanism, a rotating shaft, an impeller, a supporting rod, a material pushing plate, a scraping plate, a material storage groove, a sealing seat and powder spraying holes; powder is conveyed into the tank body through a feeding port, an external power source drives the rotating shaft to rotate, and the rotating shaft drives the impeller to move along with the rotating shaft; two kinds of modified auxiliary materials uniformly mixed by the premixing mechanism andthe powder spraying mechanism are conveyed into the material storage groove and then sprayed out while rotating along with the rotating shaft through the powder spraying holes; in the process, when powder falls into the tank body, the sprayed auxiliary materials also fall onto the powder and are uniformly mixed through stirring of the impeller, and the supporting rod rotates along with the rotating shaft and can drive the pushing plate and the scraper to rotate at high speed; and on one hand, powder attached to the inner wall of the tank body can be peeled off, and on the other hand, the speedof the powder near the tank body can be increased, and the progress of a modification reaction is accelerated. The device is simple in structure, powder and auxiliary materials are efficiently and uniformly mixed for multiple times, and the modification reaction efficiency and the modification quality are effectively improved.

Description

technical field [0001] The invention relates to a modification device, in particular to a powder modification tank. Background technique [0002] Use physical or chemical methods to treat the surface of the powder, purposely change its physical and chemical properties of the surface, and meet the specific requirements of the use of the powder surface modification process, the powder after surface modification is widely used in the national economy In various industries, the general production process of modified calcium carbonate: cleaning, drying, crushing, stacking, grinding, grading, modification, packaging. During modification production, various raw materials are put into the modification equipment, and the temperature is raised and modified through the high-speed rotation of the impeller and the direct friction of the powder. Since various raw materials are not mixed and put into the modification equipment for modification, various materials appear. Local inhomogeneit...

During modification production, various raw materials are put into the modification equipment, and the temperature is raised and modified through the high-speed rotation of the impeller and the direct friction of the powder. Since various raw materials are not mixed and put into the modification equipment for modification, various materials appear. local inhomogeneity, resulting in lower modification efficiency and quality
