Self-cleaning tank type filtering separator

Abstract

The invention discloses a self-cleaning tank type filtering separator which comprises a tank, a filtering assembly and a self-cleaning assembly. The filtering assembly comprises a filter pipe, a filter bag and the like. A filter hole is formed in the filter pipe, the upper end of the filter pipe is communicated with the interior of a water tank through a spherical pipe joint, and the filter pipe is sleeved with the filter bag which is fixed in a clamped mode. A water box and the tank are fixed. The self-cleaning assembly comprises a tank cover, a scraper blade, a scraping ring, a lead screw and the like; the tank cover is provided with a bearing pedestal and fixedly connected with the water box; the scraping ring is clamped into the scraper blade and provided with a movable clearance; the scraping ring penetrates through the filter bag and the filter pipe; a lead screw nut and the scraper blade are fixed; one end of the lead screw and the lead screw nut form a screw pair, and the other end of the lead screw is provided with a movable sealing ring, a bearing and a chain wheel and the like and assembled with the tank cover; under the drive the forward and backward rotation of the motor, the chain wheel and the chain, the lead screw automatically rotates synchronously, the scraper blade is driven by the lead screw nut to horizontally move up and down, self-adaptation adjustment of the scraping ring on the scraper blade is achieved, and the filter bag is scraped and cleaned. The self-cleaning tank type filtering separator has the advantages that the structure is novel and reasonable, the sealing performance is good, the filtering capability is high, various self-cleaning modes are adopted, and long-term automatic operation can be achieved easily.

Description

technical field [0001] The invention belongs to the technical field of solid-liquid separation, and relates to a tank-type filter separator, in particular to a self-cleaning tank-type filter separator. Background technique [0002] Powdered activated carbon (Activated Carbon, AC) is a kind of adsorption material with very developed pore structure, large specific surface area, non-toxic and tasteless, and has a strong ability to adsorb molecules. Food, environmental protection and many other fields. In terms of environmental protection, activated carbon adsorption is widely used in the purification of polluted water sources and the advanced treatment of urban sewage and industrial wastewater, and is one of the important means of treating organic wastewater. [0003] Filtration and separation equipment is used in the follow-up process of activated carbon water purification technology, which is the bottleneck restricting the wide application of powder activated carbon water pu...

AI Technical Summary

Problems solved by technology

[0005] (1) The plate and frame filter press is an intermittent filter, which occupies a large area and has a low filtration speed.

[0006] (2) Although the tank-type filter tube filter separator is continuous filtration, the filter bag is easy to block, difficult to clean, poor cleaning effect, and high replacement cost
