Abstract
The invention discloses a double-layer graphite sieve plate, which comprises a graphite sieve plate body, wherein sieve holes which are distributed uniformly are arranged in the graphite sieve plate body; a fastening ring is arranged at the periphery of the graphite sieve plate body; and filter cloth is attached to a lower layer of the graphite sieve plate body and is fixed to the lower layer of the graphite sieve plate body by the fastening ring. The double-layer graphite sieve plate is resistant to high temperature and corrosion, accurate in fineness and long in service life, the holes are not easy to block, and a sieve screen is not loaded.
Description
Technical field
The present invention relates to a kind of chemical industry equipment, be specifically related to a kind of double-layer graphite sieve plate.
Background technology
The graphite sieve plate is usually used in the solid impurity that equipment end socket side screens out material, when the impurity particle degree is little, can on sieve plate, add filter cloth.But need depending on circumstances determine whether will add filter cloth again toward contact, lose time and manpower, and not exclusively perhaps filter opening is too thin can to cause filtration because of range estimation impurity particle size is inaccurate, wastes material, uses the filter screen loading big, fragile for a long time.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of prior art, the not loading of a kind of screen cloth is provided, has been difficult for the double-layer graphite sieve plate of plug-hole.
The technical scheme that the present invention adopts: a kind of double-layer graphite sieve plate; Comprise graphite sieve plate plate body; Graphite sieve plate plate body is provided with the sieve aperture of evenly arranging; Be provided with tight loop around the said graphite sieve plate plate body, said graphite sieve plate plate body lower floor is with filter cloth, and said filter cloth is fixed on graphite sieve plate plate body lower floor through said tight loop.
Big impurity particle filters through the sieve aperture on the upper strata graphite sieve plate plate body of double-layer graphite sieve plate, and the small impurities particle filters through lower floor's filter cloth.
Beneficial effect: double-layer graphite sieve plate of the present invention is high temperature resistant, corrosion-resistant, fineness accurate, be difficult for plug-hole, not loading of screen cloth, long service life.
