Abstract

The utility model belongs to an industry and agricultural water-saving filter device, and particularly relates to a three-parallel eight-inch enlarged combined screen type filter. Three filter barrel groups with, water inlets, water outlets and upper exhaust valves are connected in parallel with water inlet pipes and water outlet pipes on the lateral surfaces and below the filter barrel groups by butterfly valves in a flexible manner, a down valve is respectively arranged below the water inlets of filter barrels, a filter screen seat ring plate is respectively welded to the inner lower portions of the filter barrels, six 304L stainless steel pieces with seat ring water-stop rubber rings are inserted into each filter barrel, and the upper side of a cylindrical filter screen is blocked while the lower side is open. Furthermore, a pressure gauge is respectively mounted at water inlets of the water inlet pipes and water outlets of the water outlet pipes. The three-parallel eight-inch enlarged combined screen type filter can realize manual hydraulic cleaning of the filter screen without pulling out the screen to clean by fresh water and a brush, is high in efficiency, saves energy as the filtered area is large and the head loss is less, and is low in management expense and labor intensity.

Description

Three eight cun increasing combination well strainers in parallel

Technical field

The utility model belongs to industry and agricultural water conservation filter, particularly three eight cun increasing combination well strainers in parallel

Background technology

At present in Treatment of Industrial Water and the water-saving irrigation progressively promoted, as waterworks water treatment and drip irrigation, the water quality requirement of domestic water and irrigation water than higher, must be in advance filtered out impurity and silt in the water by filter, in case the drip irrigation zone is stopped up and reached the domestic water standard.The filter that uses of tradition is as sandrock filter or manually clean well strainer with water.Under the same flow condition, the sandrock filter volume is big, and the big corresponding power-equipment power of the loss of flood peak is big, uneconomical; Monomer or the sandrock filter that uses in parallel must be joined special-purpose scavenging pump, when this cleans, filter to quit work or stop in the parallel connection one, and the system that influences runs well, the reduction operating efficiency.When monomer or manually cleaning well strainer with water and needing to clean with water in the course of the work of using in parallel, filter to quit work or stop in the parallel connection one, extract net and manually clean with water, the system that influences runs well, the reduction operating efficiency.In monomer or the filter vat of manually cleaning well strainer with water that uses in parallel a large diameter screen pack is housed, filter area is little, and inflow-rate of water turbine is also obviously little.

Summary of the invention

The purpose of this utility model is to provide a kind of three eight cun increasing combination well strainers in parallel, can realize manual waterpower cleaning and filtering net, needn't extract net cleans with water with clear water and brush, the efficient height, because of the loss of flood peak little and energy-conservation, administration fee and labour intensity are low, a large diameter screen pack in the unified specification filter vat is increased to the screen pack of six minor diameters, thereby has strengthened its filter area.

The purpose of this utility model: a kind of three eight cun in parallel strengthen the combination well strainers, comprise that three of having water inlet and delivery port go up the filter vat of band air bleeding valve and its side, following inlet tube and outlet tube; It is characterized in that: filter vat side, following import and export respectively are flexible coupling by butterfly valve into and out of pipe with a level and realize parallel connection, respectively set up a blowoff valve below each filter vat water inlet, it is stainless that six 304L all are installed in each filter vat, opens cylindrical screen pack under upward blocking up.A Pressure gauge is installed at the delivery port place of the water inlet of water inlet pipe and outlet pipe in addition.

Operation principle of the present utility model is: when the water that contains impurity enters in the filter chamber of filter vat from water inlet, the water that contains impurity enters when the screen pack inwall flows out from the screen pack outer wall, impurity is then on the outer wall attached to screen pack, clean water then flows out from the inwall of screen pack, cross its end opening, flow into outlet pipe for utilizing by the filter vat delivery port.Adhere to dirt on the outer wall more for a long time, and filter inlet and outlet pressure table shows certain pressure reduction, when pressure reduction reaches desired value, must carry out blowdown work; Its method is, close a water intaking valve in the Netcom in parallel, open its blowoff valve, at this moment, the part clear water that other Netcoms filter out is counter to flow in the screen pack for the treatment of blowdown, and flow out to the net outer wall from the net inwall, force the dirt that is adsorbed on the net outer wall to leave, and outside sewage draining exit is got rid of bucket, carry out backwash, after seeing clear water, close its blowoff valve and open water intaking valve, make it enter normal operating conditions; Then next filter vat is carried out backwash work, its method is the same.The utility model realizes that manual waterpower backwash effect is good, do not need hand brush to clear up overanxious net, filter area is big, the loss of flood peak is little, and good energy-conserving effect cleans convenient and swift, administration fee and labour intensity are low, embody the superiority of water-saving irrigation technique, make water-saving irrigation be rendered as energy-conservation irrigation, quicken its popularity rate in the place.
