Ball milling equipment for piezoelectric ceramic production

Abstract

The invention relates to ball milling equipment for piezoelectric ceramic production. The ball milling equipment comprises a base, a motor, a main body, a first bearing, two rotating shafts and two supporting rods, and further comprises a heat dissipation mechanism and two vibration mechanisms. The heat dissipation mechanism comprises a fixed box, two water boxes, two water spraying assemblies, two power assemblies, two transmission assemblies and a plurality of heat dissipation plates, wherein each water spraying assembly comprises an air cylinder, a first connecting pipe, a second connectingpipe, a spraying pipe, two water spraying units and a plurality of nozzles. Each vibration mechanism comprises a power disc, a vibration plate and two limiting assemblies. The ball milling equipmentfor piezoelectric ceramic production achieves the function of heat dissipation of the main body through the heat dissipation mechanism, and the situation that the equipment is damaged due to the factthat the temperature of the main body is too high is avoided. Through the vibration mechanisms, the vibration function of the main body is achieved, the number of times of collision between steel balls in the main body is increased, the number of times of collision between the steel balls and materials is also increased, and therefore the crushing speed is increased, and the crushing effect is improved.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a ball milling device for piezoelectric ceramic production. Background technique [0002] New materials refer to newly developed or developing structural materials with excellent performance and functional materials with special properties. Among them, piezoelectric ceramics are a kind of new materials, and piezoelectric ceramics are a kind of materials that can convert mechanical energy and electrical energy into each other. Information functional ceramic materials-piezoelectric effect, piezoelectric ceramics not only have piezoelectricity, but also have dielectric properties, elasticity, etc., and have been widely used in medical imaging, acoustic sensors, acoustic transducers, ultrasonic motors, etc. In the production process of existing piezoelectric ceramics, ball milling equipment is used to fully pulverize raw materials.

AI Technical Summary

Problems solved by technology

[0003] When the existing ball mill is in use, more heat is generated inside the main body due to the collision and friction between the steel ball and the raw material, which leads to an increase in the internal temperature of the main body, thereby increasing the probability of damage to the internal parts of the main body, thereby affecting the normal operation of the equipment. The reliability of the existing ball mill is reduced. Not only that, but the existing ball mill usually relies on the collision between the steel ball and the raw material to realize the crushing work, because the steel ball generally hits the raw material from top to bottom, resulting in a single crushing method , making the crushing of raw materials insufficient, increasing the crushing time and reducing the crushing quality
