CN2464423Y - Horizontal counter-washing water filter - Google Patents

Abstract

The utility model relates to a horizontal counter-washing water filter, which is composed of a main body and a driving device. The utility model can be used for industrial circulating water treatment and sewage treatment. The main body comprises a rough filtration section and a refined filtration section. Due to the adoption of hierarchical filtration, the volume of the utility model can be reduced, and the filtration is more thorough. By using the way that the utility model is controlled by a differential pressure device and a PLC programmable controller, the automatic control cleaning can be realized. Water consumption and pressure losses can be reduced in the process of cleaning, the water supply flow quantity and the water supply pressure of end users can be effectively ensured, and the existing faults of other products can be overcome.

Description

Horizontal automatic anti-rinse water filter

The utility model belongs to the design and the manufacturing technology field of anti-rinse water filter.

Employed anti-filter rinsed in actual production mostly adopts single net tube single suction to chew filter and many filter cores type filter etc. at present.But the limitation that they all have certain defective and use.A single net tube single suction is chewed filter owing to have only a suction to chew, and inhales the aperture area of chewing for the online filter cake of cleaning and filtering effectively just must strengthen, strengthens the latus rectum of cleaning arm volume and increase blowoff valve, so just causes complex structure, the equipment volume increase.Again because need a large amount of anti-cleanings of filtered water, so can not guarantee terminal use's output.Many filter cores type filter is because the diameter and the length of filter core can not be done very for a short time, so the bore of cleaning arm must be done greatlyyer, water consumption is higher during blowdown, and scavenging period is longer, also causes the output of terminal water and pressure all to be affected.And the volume of above two kinds of filters is all very big, needs independent the installation, not only takies very big space, but also will stamp than firm foundations, so can't come into operation with the place of a lot of limited space systems.Therefore say that above two kinds of products are very undesirable in actual applications.

It is less and need not to take up space in addition, can be directly installed on and realize classified filtering, the anti-cleaning and water consumption and crushing is all very little, can guarantee the horizontal automatic anti-rinse water filter of the normal water of terminal use when cleaning during anti-cleaning the stage by stage on the water supply line, in same equipment that the purpose of this utility model provides a kind of volume.

The utility model is achieved by following technical solution, and its structure as shown in drawings; Constitute by body and drive unit.Body (15) is cylindric, has flange (5) at its two ends.Pars intermedia at body has a dividing plate (11).On right side, body bottom one delivery port (22) is arranged, a water inlet (20) is arranged in the left side.One differential pressure device (21) is arranged between two mouths of a river.One blow-off pipe (4) is arranged on the flange of left side, a blow-off pipe (16) is also arranged on the flange of right side, two sewage draining exits are by electrical ball valve control.Upper left quarter at body has a vent valve (24).Have drive unit support (3) in the body left side, this device is fixed on the flange of left side.The support left side has drive unit (1).Have driving shaft (2) on the drive unit.Have smart the filtration in the left side of body internal partition and instead clean the person in charge (8), have several smart filter suctions on the person in charge and chew (10), inhale to chew and enclose the person in charge by five equilibrium angle, alternating expression arrangement up and down.Anti-cleaning is responsible for and is connected with driving shaft.Near flange place, left side one blowdown chamber (7) is being arranged.Have smart filter screen (9) in the outside that suction is chewed.Smart filter screen is cylindric, and two ends are separately fixed on flange and the dividing plate.Have the anti-scavenge pipe of coarse filtration (13) on the anti-cleaning person in charge of essence filtration right-hand member, have several coarse filtration suctions on the scavenge pipe and chew (14), the arrangement setting that this suction is chewed is chewed identical with essence filter suction.Chew the outside in the coarse filtration suction and have coarse strainer (12).Blow-off pipe (4) is connected with the blowdown chamber.Blow-off pipe (16) is connected with the anti-scavenge pipe of coarse filtration.

The utility model is used for industrial circulating water and sewage disposal system.Only need during use its water inlet and delivery port are connected on the waterline and can work.The water that needs to handle enters in the coarse strainer from the water inlet, under pressure, enters smart filter screen through coarse strainer, flows out from delivery port through pressure again, and water promptly disposes.Some impurity promptly are filtered on the inwall of filter screen.When long-time use, the foreign material that accumulate in the screen pack inboard are cumulative, form filter cake, will form pressure reduction like this between inlet tube and coarse filtration chamber, when pressure difference reaches one regularly, will influence the pressure of supply water in coarse filtration chamber.At this moment, differential pressure device will send signal, PLC controller by the equipment electric-control system sends instruction to the electronic blowoff valve of drive unit and coarse filtration chamber one side, drive unit promptly drives blow-off pipe and does axially back and forth and radially rotatablely move, the suction that distributes on the blow-off pipe is chewed also along with motion, meanwhile, electronic blowoff valve is also opened automatically.When blowoff valve is opened, make in suction and chew and coarse strainer touching position formation negative pressuren zone, at this moment the water in the screen cloth outside will instead flow to inhale chew in, also the filter cake on the coarse strainer is poured simultaneously inhale chew in, discharge through blow-off pipe and blowoff valve that this is external, screen cloth has obtained cleaning and has recovered its function, it is normal that pressure recovers, drive system shuts down, and blowoff valve cuts out, and the anti-cleaning process of coarse strainer finishes.Water after the coarse filtration flows to smart screen pack inboard by the through hole of offering on the dividing plate (11), flows to the screen cloth outside by the pressure effect, flows out by delivery port and supplies with terminal, and the user finishes for the second time and filters.Remainingly in the water just hindered in fie screen on the side net wall than granule through coarse filtration net filter back.When process works long hours, between delivery port and smart filter chamber, also can form pressure reduction, when reaching certain value, utilize with the anti-said function that cleans of coarse filtration and clean, finish smart anti-cleaning process of filtering.

The utility model is reasonable in design, owing to adopt classified filtering, has not only dwindled the volume of equipment, and has filtered more thorough.Instead clean stage by stage by differential pressure system and PLC Programmable Controller, the water when greatly having reduced anti-the cleaning consumes and crushing, has guaranteed terminal use's water supply flow and pressure of supply water effectively, has overcome the disadvantage of other products, and using can be more extensive.
