Screening device for preparing dielectric ceramic powder

Abstract

The invention discloses a screening device for preparing dielectric ceramic powder and belongs to the technical field of dielectric ceramic powder preparation. According to the key points of the technical scheme, the screening device is characterized by comprising an equipment box, a feeding device is arranged at the top of the equipment box, the feeding device penetrates through the equipment boxand extends into the equipment box, and through arranging a smashing device, integration of smashing and screening can be realized, and the usability of the device is improved, in addition, multiplerotating rods are used for staggered crushing, the crushing effect is better, by arranging a sieve plate device, graded sieving can be conducted on ceramic powder, unqualified ceramic powder can be directly sieved out, the sieving effect is improved, and under driving of an electric push rod, two strip-shaped plates can realize automatic cleaning, manual dismounting and cleaning are not needed, the maintenance difficulty is reduced, the cleaning efficiency is improved, the screening effect of the sieve plate device is guaranteed, a screening box can be driven to move up and down by arranging areciprocating assembly, ceramic powder is prevented from being accumulated on the strip-shaped plates, and the screening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of dielectric ceramic powder preparation, and more specifically relates to a screening device for the preparation of dielectric ceramic powder. Background technique [0002] Ceramic powder, also known as dielectric ceramic, is a functional ceramic that has polarization ability under the action of an electric field and can establish an electric field in the body for a long time. According to its use and performance, it can be divided into electrical insulation, capacitor, piezoelectric, pyroelectric and ferroelectric ceramics. , has the characteristics of high insulation resistivity, small dielectric constant, small dielectric loss, good thermal conductivity, small expansion coefficient, good thermal stability and chemical stability, etc. It is used for installing, fixing and protecting electronic components, as a current-carrying conductor Ceramic materials for insulation support and various circuit substrat...

AI Technical Summary

Problems solved by technology

[0003] Ceramic powder needs to be crushed and sieved before being produced. The existing sieve plate device cannot achieve the purpose of crushing and sieving at the same time, and the practical effect is not strong. It is inconvenient to clean the sieve plate during use. After a long time, the screening effect will be affected, and the ceramic powder that is screened out cannot realize automatic circulation, and needs to be collected and discharged, which is labor-intensive. Therefore, those skilled in the art provide a dielectric ceramic powder. Screening device, to solve the problems raised in the above-mentioned background technology
