Sieve plate made of graphite

Abstract

The invention discloses a sieve plate made of graphite. The sieve plate comprises a sieve plate body, the sieve plate body is provided with sieve pores, the sieve pores are circumferentially distributed in the sieve plate body, and the circumferences formed by connecting the sieve pores form concentric circles. The sieve plate made of the graphite has the properties of high strength, temperature resistance, corrosion resistance, accurate fineness, pore blockage resistance and the like; meanwhile, the material adopted in the sieve plate has high abrasion resistance, and the screen is unloaded, so that the sieve plate has long service life, the frequency of changing the sieve surface is reduced, the production cost of an enterprise is reduced, and the production efficiency can be effectively improved.

Description

technical field [0001] The invention relates to chemical equipment, in particular to a graphite sieve plate. Background technique [0002] Graphite sieve plate is often used to screen out solid impurities from materials on the side of the equipment head. When the particle size of impurities is small, filter cloth can be added to the sieve plate. Another function of the sieve plate is to evenly distribute the material, so as to prevent the material from only passing through part of the channel of the equipment, resulting in incomplete utilization of the equipment and failing to meet the process requirements. At present, most of the sieve plates used for material screening are metal sieve plates. Due to the inherent defects of metal materials, these metal sieve plates have poor corrosion resistance and wear resistance, and their service life is short. In order to solve this problem, for example, the patent application No. 200920102045.4 relates to a wear-resistant rubber siev...

Problems solved by technology

At present, most of the sieve plates used for material screening are metal sieve plates. Due to the inherent defects of metal materials, these metal sieve plates have poor corrosion resistance and wear resistance, and their service life is short.

In order to solve this problem, for example, the patent application No. 200920102045.4 relates to a wear-resistant rubber sieve plate. The wear-resistant rubber sieve plate has good wear resistance, but poor cold resistance, temperature resistance and processability, and high cost
