Description
Technical field
The utility model relates to a kind of filter, belongs to separation field.
Background technology
In industrial production, the process of sewage, chemical reagent are reclaimed and the purification etc. of liquid all needs filter operation.Filter the penetration by liquid medium namely in motive force or other External Force Acting low suspension liquid, solid particle and other materials are filtered medium and retain, thus the process of separating solids and other liquid.
Current filter is varied, but the filtering interface of most of filter is perpendicular to pipeline.This structure is convenient to manufacture; but suspension is when through medium; by vertical impact filtering interface; in this situation, impulsive force is large; not only filter media surface can be destroyed; and some less particles can through medium under impact force action, reduce over filter medium service life, thus reduce filter efficiency.In addition, the impulsive force only by pumping current during traditional filter device backwashing is rinsed, and the method exists the halfway defect of cleaning, and rinses for a long time, will cause the waste of water resource.
For the defect that traditional filtering equipment exists, the utility model is by changing the angle of filtering interface and pipeline, and introducing air bag back-flushing structure, is the raising of filter efficiency, and the prolongation of service life of equipment and the thoroughly clean of filter plant provide possibility.
Summary of the invention
The utility model proposes a kind of filter, object cleans halfway defect to solve filter medium in traditional filtering device, and improve filter efficiency, more effective obstruct particulate is through interface simultaneously.Filtering interface and pipeline have the impulsive force of the structure of certain angle and air bag back-flushing structure not only slowing down fluid, and strengthen the cleaning capacity to filter medium, thus the extension device maintenance interval time limit, improve industrial production benefit.
The utility model discloses a kind of filter, belong to separation field, mainly comprise air bag, wireway, gas valve, inlet valve, inlet duct, procapsid, back casing, filter, connecting plate, drainage pipeline, draining valve, packing ring, outlet valve and outlet conduit, wherein air bag is connected with wireway, inlet duct and guide pipeline are all positioned at above procapsid, drainage pipeline is positioned on the downside of procapsid, be installed between procapsid and back casing with 45 ° of inclination angles after filter and washer combinations, procapsid is connected by connecting plate bolt with back casing, outlet conduit is positioned at bottom back casing.
The utility model proposes a kind of filter, wherein be installed between procapsid and back casing with 45 ° of inclination angles after filter and washer combinations, under hydraulic shock effect vertically downward, the impulsive force of liquid is separated into perpendicular to filter and the shunting being parallel to filter, thus weaken water impact, avoid particulate through filter under high speed and high pressure, ensure filter efficiency, extend filter medium service life simultaneously.
The utility model proposes a kind of filter, wherein air bag is connected with wireway, and inlet duct and guide pipeline are all positioned at above procapsid, composition air bag back-flushing structure.After in air bag, gas drains, all valve closings, only open inlet valve, introduce current, then inlet valve is closed, open gas valve, liquid upwards attracts by the negative pressure in air bag, and then extruding gasbag, by contraction and the expansion of air bag, fluid is vibrated repeatedly, oppositely pulls out the particle on filter, thus reach thoroughly clean object.
The utility model proposes a kind of filter, wherein drainage pipeline is positioned on the downside of procapsid, and outlet conduit is positioned at bottom back casing, and these pipelines and inlet duct form backwashing system jointly.Close gas valve, other valve opens, inlet duct and outlet conduit feed water simultaneously, inlet duct water intake velocity is less than outlet conduit water intake velocity, particle on filter pours to drainage pipeline by its pressure differential formed, not only remove filter surface particle, and inner for filter larger particles can be removed.
The utility model proposes a kind of filter, wherein procapsid is connected by connecting plate bolt with back casing.When filter reaches service life or needs the filter changing other types or material, can, by bolt connection disassembling, procapsid be separated with back casing, take out filter.
The utility model, in conjunction with air bag back-flushing structure and band angle filter structure, by controlling the switch of each valve, realizes the multidirectional pre-washing function of filter, under avoiding large impact power simultaneously, particulate, through medium, provides good filter effect, for industrial purification demand provides safeguard.

In figure: 1-air bag, 2-guide pipeline, 3-gas valve, 4-inlet valve, 5-inlet duct, 6-procapsid, 7-filter, 8-connecting plate, 9-drainage pipeline, 10-draining valve, 11-packing ring, 12-outlet valve, 13-outlet conduit, 14-back casing.
Detailed description of the invention
As depicted in figs. 1 and 2, the utility model discloses a kind of filter, belong to separation field.It mainly comprises air bag 1, wireway 2, gas valve 3, inlet valve 4, inlet duct 5, procapsid 6, back casing 14, filter 7, connecting plate 8, drainage pipeline 9, draining valve 10, packing ring 11, outlet valve 12 and outlet conduit 13.Wherein air bag 1 is connected with wireway 2, inlet duct 5 and guide pipeline 2 are all positioned at above procapsid 6, drainage pipeline 9 is positioned on the downside of procapsid 6, be installed between procapsid 6 and back casing 14 with 45 ° of inclination angles after filter 7 and packing ring 11 combine, procapsid 6 is connected by connecting plate 8 bolt with back casing 17, and outlet conduit 13 is positioned at bottom back casing 14.
An embodiment as shown in Figure 1, in normal conditions, is closed draining valve 10 and gas valve 3, is opened inlet valve 4 and outlet valve 12, and liquid, from the top down through procapsid 6, through filter 7, arrives back casing 14.
When shut-down backwash, gas valve 3 is closed, open inlet valve 4, outlet valve 12 and draining valve 10, inlet duct 5 is poured water downwards, and water velocity is 0.8m/s, and outlet valve 12 upwards feeds water, water velocity is 1m/s, and the particle washed out that recoils flows out from drainage pipeline 9.Then draining valve 10, inlet valve 4 and gas valve 3 is closed, open outlet valve 12, upwards feed water, keep negative pressure in air bag 1, when confluent reaches 1/3, close outlet valve 12, open gas valve 3, by coordinating of external pressure and hydraulic pressure, make contraction and the expansion of air bag 1 regularity, make water flow vibration, thorough cleaned filter plate 7.
When shut-down (breakdown) mainteance, bolt on connecting plate 8 is turned on, procapsid 6 is separated with back casing 14, change packing ring 11 and filter 7.
