Inverted-umbrella-shaped plate filter

Abstract

The invention relates to the technical field of liquid material filtering machinery, in particular to an inverted-umbrella-shaped plate filter. The inverted-umbrella-shaped plate filter comprises a cylinder and is characterized in that a rotatable hollow-tube-shaped rotary shaft is mounted in the cylinder, the upper end of the hollow-tube-shaped rotary shaft is connected with a drive device located outside the cylinder through a spindle, an inner bearing is arranged inside the bottom end of the hollow-tube-shaped rotary shaft, the lateral side of the lower end of the cylinder is provided witha liquid discharge through hole, a liquid outlet pipe is mounted in the liquid discharge through hole, one end of the liquid outlet pipe is connected with the inner bearing, the other end of the liquid outlet pipe is located outside the cylinder, the bottom of the cylinder is provided with a residue outlet, a spirally arranged disc plate is mounted on the outer surface of the hollow-tube-shaped rotary shaft, the interior of the disc plate is communicated with the hollow-tube-shaped rotary shaft, the upper surface of the disc plate is provided with an annular groove, and an annular filter layeris mounted in the annular groove. The inverted-umbrella-shaped plate filter has the advantages that continuous filtering can be achieved, discharged filter pulp is low in moisture content, and production efficiency can be increased.

Description

technical field [0001] The invention relates to the technical field of liquid material filtering machinery, in particular to an inverted umbrella plate filter. Background technique [0002] In the fine chemical industry of dyes, pigments, pharmaceuticals, synthetic resins, etc. and various waste liquid treatment industries, the original plate and frame filter press controls the filtration process by the filter cake, due to the deformation of the solid particles in the filter cake and the change in porosity Small, it will cause the increase of filtration resistance. As the filtration progresses, the filter cake will continue to thicken, and the permeability will decrease, the residence time will prolong, and the filtration speed will decrease. Finally, the filtration cannot be carried out, and continuous operation cannot be performed. The pulp moisture content is high and cannot be adjusted freely, and it also needs a lot of lotion and time when cleaning, and the production e...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems that the existing plate and frame filter press cannot continuously filter, the discharged filter pulp has high moisture content, and the production efficiency is low, the present invention provides an inverted umbrella type plate filter, which can realize continuous filtering operation and discharge the wet filter pulp. Low content rate, improve production efficiency
