Abstract

The invention discloses production equipment of an asymmetric tubular filter element body. The asymmetric tubular filter element body comprises a tubular and porous support body and a coating locatedon the inner wall of the support body, wherein the coating is formed by attaching slurry to the inner wall of the support body and drying the slurry. The production equipment comprises sealing parts,a grouting mechanism and a driving assembly for driving the support body to rotate in the horizontal direction; the sealing parts comprise a first sealing part and a second sealing part which are matched with two ends of the support body respectively; the grouting mechanism comprises slurry circulation channels which are formed in the first sealing part and / or the second sealing part to communicate the inside and the outside of the support body; the driving assembly comprises rotating shafts connected with the first sealing part and the second sealing part and a motor for driving one rotatingshaft to rotate. The production equipment integrates grouting and centrifugation, can produce the coating with uniform thickness and is high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of asymmetric tubular filter elements, in particular, to manufacturing equipment for an asymmetric tubular filter element blank. Background technique [0002] The asymmetrical tubular filter element refers to an asymmetrical tubular filter element whose filter pore diameter changes in a gradient in the filtering direction. The pore size of the asymmetric tubular filter element increases or decreases sequentially from the inside to the outside along the radial direction. Wherein, the inner layer structure of the asymmetric tubular filter element whose pore diameter increases sequentially is called the inner membrane, and the outer layer structure is called the support body; the inner layer structure of the asymmetric tubular filter element whose pore diameter decreases sequentially is called For the support body, the outer structure is called the adventitia; the inner and outer membranes can be collectively ...
