Self-cooling grinding mechanism

Abstract

The invention discloses a self-cooling grinding mechanism which comprises an upper grinding disc, a lower grinding disc, partition plates, an upper grinding disc fixing shell, a lower grinding disc fixing shell, a rotating shaft and a water slip ring. Spiral water tanks are formed in the bottom surfaces of the upper grinding disc and the lower grinding disc, the partition plates are fixed to the bottom surfaces of the upper grinding disc and the lower grinding disc, and cooling channels are formed by the partition plates and the spiral water tanks. The upper grinding disc and the partition plate thereof are fixed in an upper grinding disc fixing shell after being inverted, and the lower grinding disc and the partition plate thereof are fixed in a lower grinding disc fixing shell. The rotating shaft penetrates through the centers of the upper grinding disc, the lower grinding disc, the partition plates, the upper grinding disc fixing shell and the lower grinding disc fixing shell, and the lower grinding disc and the lower grinding disc fixing shell are fixedly connected with the side wall of the rotating shaft. The water slip ring sleeves the rotating shaft and is positioned below the lower grinding disc fixing shell, and a water inlet and a water outlet of the water slip ring communicate with two ends of the cooling channel correspondingly. The grinding mechanism is fast in heat exchange, grinding heat can be taken away at a high speed, and the problem that ground materials are prone to oxidative deterioration at a high temperature is solved.

Description

technical field [0001] The invention relates to the field of high-speed pulverizers, in particular to a pulverizing mechanism with self-cooling function. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] The high-speed pulverizer is a device that uses the high-speed relative motion between the movable toothed disc and the fixed toothed disc to make the pulverized material be crushed through the comprehensive action of tooth impact, friction and impact between objects, etc. Powder required. At present, high-speed mills have been widely used in pharmaceutical, chemical, pesticide, food and grain industries. However, the high-speed mill will generate a lot of w...

AI Technical Summary

Problems solved by technology

However, the high-speed mill will generate a lot of waste heat when it rotates at high speed. In severe cases, the temperature of the grinding disc can reach as high as 80°C, causing the oxidative deterioration of the ground material

The existing cooling device is to set the wall of the mill shell as a cavity and use tap water to cool and circulate, but it has no actual cooling effect on the grinding particles.
