Description
Technical Field
The utility model relates to the technical field of dry-wet separation and extraction of materials in the pharmaceutical, chemical and food industries, in particular to a gas backflushing material removing mechanism of a bag-pulling centrifuge.
Background
The bag pulling centrifuge is a common material dry-wet separation device, liquid in the material is thrown out of an inner container through centrifugal motion, and solid particles are intercepted through a filter bag. As the production is carried out, solid particles form a filter cake on the surface of the filter bag, and the filter bag needs to be unloaded and cleaned.
Most of filter cake layers on the inner wall of a rotary drum (inner container) can be scraped off by a hydraulic scraper when the existing bag-pulling centrifuge discharges materials. In order to prolong the service life of the filter bag and prevent the filter bag from being damaged, a gap of 2-3mm is usually left between the scraper and the filter bag, so that a thin layer of residue is left on the filter bag in the scraping process, and the residual solid particles on the filter bag can be removed by pulling the filter bag in the liner.
In the actual production process, residues can be removed from the filter bag at a place with large action amplitude during stretching, but solid materials are remained at a place with small action amplitude, and particularly the upper part of the filter bag is easier to remain. The presence of residues can lead to an unbalanced movement of the drum, which can cause vibrations during the operation of the plant, and for some products, if not cleaned in time, the residues can also contaminate the next batch of material, causing irreparable damage, and corresponding improvements are required.
