Description
technical field
The present invention relates to a kind of filter.
Background technology
In fields such as metallurgy, electric power, oil, chemical industry, medicine, food, printing and dyeing, papermaking, urban water supply, central air-conditioning, river water cleaning, middle water treatment, agricultural irrigation, sewage disposals, filter is widely used in filtration and the separation process of the fluids such as water, emulsion in various lubricated, cooling, production systems, and what at present a lot of enterprises were used remains traditional filter.
The cartridge structure of traditional filter plant is the many filter element filterings structure that adopts single filter cylinder filtration or the multiple different filter cores of the inside stack mostly.Many filter element filterings equipment filters layer by layer, good filtration effect, but its filtration water yield is few, the aquifer yield of filter plant is little, filter lost efficacy after easy to clean not, when cleaning, not only take time and effort, and waste the more energy and water source, even transfer to lose efficacy because filter core is irreversible, be used for the filtration of meticulous a small amount of water.Single filter cylinder filter plant is with above-mentioned many filter element filterings equipment same volume in the situation that, and the filtration water yield is larger, and single net cartridge structure, once strainer filtering lost efficacy, be easier to clean up, continue to use, according to the size of its filter screen hole, can be used on different occasions, its range of application is wider, but because its filter cylinder is single filter structure, process the water of identical water quality, its poor filtration effect, so, be often used in conjunction with other filter.Existing sewage treatment project, the water yield of water-supply systems and intermediate water reuse system processing is increasing, filter area in single net filter cylinder filter plant unit volume is little, filter the water yield or little, aquifer yield is little, be used in the filtration of above-mentioned large water gaging, need to increase number of devices, greatly increase equipment investment and floor space.Its backwash adopts automatic back-washing system, and when its work, water enters from entrance, discharges from outlet through filter cylinder, and impurity is trapped within filter cylinder outer surface, and inlet outlet pressure differential increases.In the time that pressure reduction reaches setting value, automatic control system starts backwashing system, and the electrically operated valve of sewage draining exit is opened, filter cylinder rotation, and while forwarding soil pick-up groove to, backwash current from inside to outside rinse, and dirt is rinsed out, and discharge through sewage draining exit.Filter cylinder rotates a circle, and whole surface is cleaned.Backwash process finishes, the stall of blowoff valve disable motor.When the operation of this filter, still there is following shortcoming: effect that (1) is counter while cleaning is poor, stop up when serious and need artificial unloading's filter cylinder to clean, labor intensive material resources; (2) effective filtration area is still very little, and the filtration water yield is few, and production efficiency is low; (3) must stop filtration and just can carry out backwash, the filtration water yield is few, and production efficiency is low; (3) water, recycling in process, is unavoidably infected with dirt, bacterium etc., and the hardness ions such as calcium, magnesium in water also can constantly concentrate, and these factors all can cause filter life to shorten, and filtering water declines.
Summary of the invention
