Abstract

The invention discloses a centrifugal film coating apparatus, which comprises a base and a centrifugal film coating device arranged on the base. The centrifugal film coating device comprises a film coating tool, a transmission sleeve shaft, a drive motor and a drive control system, wherein the film coating tool is arranged in the horizontal direction, continuously rotates and simultaneously drives internal materials to carry out centrifugal motion; the transmission sleeve shaft is coaxially sleeved outside the film coating tool and drives the film coating tool to continuously rotate; the drive motor is connected with the transmission sleeve shaft; the drive control system controls and adjusts the rotating direction and the rotation of the drive motor; and the left end part and the right end part of the transmission sleeve shaft have openings and the right ends of the left end part and the right end part are assembled with a U-shaped compressing member through a plugging member, and the left end is assembled through a Pi-shaped compressing member. The invention has the advantages of simple structure, simple and convenient using operation, low noise, safe and reliable operation, recyclable slurry, high rotation speed and high efficiency, can completely meet the technical requirement on molding centrifugal classification deposition, and solves the actual problem that the powder with different granularities is deposited in turn.

Description

technical field [0001] The invention belongs to the technical field of microporous metal inner wall membrane preparation, and in particular relates to a centrifugal coating equipment. Background technique [0002] Microporous metal separation membrane is a new type of metal porous material. The international GKN company adopts powder wet spraying technology to prepare stainless steel outer wall membrane material. The filtration accuracy is 2.0μm (efficiency is 98%), and the relative air permeability coefficient is 3m 3 / (m 2 ·KPa·h). In actual working conditions, microporous metal inner wall membrane materials have greater advantages, such as good backflushing effect, and the membrane layer is not easy to be polluted and damaged. However, the preparation methods of microporous inner wall membrane materials at home and abroad are still immature. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a centrifugal film ...
