Abstract

The invention relates to the field of filtering devices, and discloses a rotary drum vacuum filter for alkali-making filtration. The rotary drum vacuum filter for alkali-making filtration comprises anouter box, a base is fixedly mounted at the bottom of the outer box, a control panel is fixedly mounted at the right side of the front surface of the outer box, a supporting plate is fixedly mountedat the top of the front surface of the outer box, a first motor is fixedly mounted at the top of the supporting plate, and two vertical plates are fixedly mounted at the front side and the back side of the top of the outer box respectively. The rotary drum vacuum filter for alkali-making filtration is provided with a sliding block, a fixed sleeve plate and a sleeve plate, a scraping plate scrapesa filter cake formed on the surface of a rotary drum, a distance between the scraping plate and the rotary drum can be changed by stretching the sliding block when the filter cake is not scraped off completely in order to change the position of the scraping plate, and a rolling ball is arranged to reduce the resistance borne by the sliding block in the process of the sliding block sliding along asliding groove formed in the top of the outer box, so it is guaranteed that the filter cake formed on the surface of the rotary drum can be completely cleaned up, and the scraping efficiency of the rotary drum vacuum filter is improved.

Description

technical field [0001] The invention relates to the technical field of filtering equipment, in particular to a rotary drum vacuum filter for alkali making and filtering. Background technique [0002] Sodium carbonate is also called soda ash. The drum vacuum filter uses negative pressure as the driving force for filtration. The filter surface is a continuous filter on the surface of a cylindrical drum. It is generally used in some sectors such as alkali making and mining industries, mainly for solid-liquid separate. [0003] The existing drum vacuum filter is equipped with a scraper to scrape the filter cake formed on the surface of the drum, but the position of the scraper is fixed, and the filter cake formed on the surface of the drum cannot be completely removed, reducing the In addition, the filter screen fixedly installed on the surface of the drum is prone to clogging, and there is no cleaning tool for the filter screen on the equipment, which affects the filtration ef...
