Abstract
The invention relates to a backwashing loose filter. The filter comprises a filter main body, a water inlet, a water outlet, a backwashing water inlet, a backwashing water outlet, a backwashing hydraulic device, a filter material and a filter screen cover, the backwashing hydraulic device is arranged at the top of the filter main body, the device is connected with a telescoping pressure bar, and the tail end of the telescoping pressure bar is connected with a filter screen. The backwashing loose filter has the advantages of simple structure, high work efficiency, long service life, cleaning convenience, large cleaning water flow, good cleaning effect, high filtering treatment efficiency, small backwashing water consumption of the whole filter, and running cost reduction.
Description
Technical field
The environment-protective water treating apparatus that the present invention relates to solid in a kind of filtering liquid or colloidal particle, relates in particular to a kind of backwash loose type filter.
Background technology
Filter single-filtering no matter, or many filters in the market, the rinse water flow of unit are filter core is very little, and cleaning performance is poor, and treatment effeciency is not high, and whole filter backwash water consumption is very large; In the more complicated occasion of water quality situation, may cause because of the foreign material in liquid filter core or scraper plate to damage and reduce service life.
Summary of the invention
The present invention provides a kind of simple in structure, good filtration effect, high, the water-saving backwash loose type of backwash efficiency filter in order to overcome the above problems.
Technical scheme of the present invention is: comprise filter body, water inlet, delivery port, backwash water inlet, backwash delivery port, counter-flushing liquid pressure device, filtrate and screen cover, described counter-flushing liquid pressure device is arranged on filter body top, this device connects a flexible depression bar, and described flexible depression bar end connects a filter screen.
Described screen cover is arranged on filter body bottom, and screen cover surrounding arranges some filtrates.
Described delivery port and backwash water inlet are set to two arms, are respectively equipped with valve on arm.
Described water inlet and backwash delivery port are set to two arms, are respectively equipped with valve on arm.
Described screen cover bottom is provided with ultrasonic unit.
The present invention is simple in structure, operating efficiency is high, long service life, easy to clean, and rinse water flow is larger, and cleaning performance is good, and filtration treatment efficiency is high, and whole Filter Back Washing water consumption is less, reduces operating cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1 is filter body, the 2nd, and water inlet, the 3rd, delivery port, the 4th, backwash water inlet, the 5th, backwash delivery port, the 6th, counter-flushing liquid pressure device, the 7th, screen cover, the 8th, flexible depression bar, the 9th, filter screen.
The specific embodiment
A kind of backwash loose type filter, comprise filter body 1, water inlet 2, delivery port 3, backwash water inlet 4, backwash delivery port 5, counter-flushing liquid pressure device 6, filtrate and screen cover 7, described counter-flushing liquid pressure device 6 is arranged on filter body 1 top, this device connects a flexible depression bar 8, described flexible depression bar 8 ends connect a filter screen 9, described screen cover 7 is arranged on filter body 1 bottom, screen cover 7 surroundings arrange some filtrates, described delivery port 3 and backwash water inlet 4 are set to two arms, on arm, be respectively equipped with valve, described water inlet 2 and backwash delivery port 5 are set to two arms, on arm, be respectively equipped with valve, described screen cover 7 bottoms are provided with ultrasonic unit.
During running, need the oil-polluted water of filtration, flow into by the filtrate of 8 filter screens that connect 9 compressions on flexible depression bar, after media filtration, containing oil suspensions and part oil, can be trapped by the filtrate of surperficial oleophilic drainage, allow water pass through, realize fast decontaminating, complete filter; When filtrate, hold back material and increase, the loss of flood peak strengthens, and while reaching certain hydraulic pressure, starts counter-flushing liquid pressure device 6, and the depression bar 8 that will stretch is pulled upwardly, and the quick filtrate space that increases thereby band electric filter 9 rises, forms higher negative pressure fast; The reverse air water of backwash, high pressure washes away filtrate, the greasy dirt of filter material surface is washed away fast, and be rushed out outside filter body 1, under higher water velocity, containing oil suspensions and part oil, can depart from material surface, simultaneously screen cover 8 High Rotation Speeds, get rid of the greasy dirt on screen cover 8, thereby reach the effect of backwash.
