Background technology
Filtration belongs to indispensable processing means in the water purification process, is used for the impurity of interception water, with purify water or protection system in the operate as normal of other equipment.Common well strainer is because of its good filtration effect, the little fields such as water source filtration, industrial cycle water system that are widely used in of resistance, but that its shortcoming is pollutant holding capability is little, be subject to that dirt stops up, the cleaning complexity, must dismantle the cleaning that could realize filtration fraction to equipment, state that can't monitor filter, and it is bigger influenced by human factor, makes the automaticity of whole system very low.In addition, owing to screen pack could be taken out after other pipeline need being taken away, extremely inconvenient for the maintenance of screen pack, reduced operating efficiency.
The utility model content
In order to address the above problem, the utility model has designed a kind of full-automatic two net backwash filters for agricultural water-saving irrigation system, utilize two net pressure reduction to carry out backwash, can irrigate continuously, it is anti-cleaning automatically while irrigating, the automaticity height, treating capacity is big, can clean blowdown and uninterrupted the irrigation voluntarily, cleaning performance is good automatically, and application surface is extensive, and screen pack can directly take out, need not to move other pipelines, the save trouble and labor is very easy to the maintenance to screen pack again.
The technical solution of the utility model is:
A kind of full-automatic two net backwash filters for agricultural water-saving irrigation system, comprise tank body, described tank body is respectively equipped with water inlet pipe, outlet pipe and blow-off pipe, be connected with two-way screen pack pipeline between described water inlet pipe and the blow-off pipe, be respectively first via filter pipe and second and pass by the chimney filter road, be respectively arranged with first electromotive intake valve, first screen pack and the first electronic blowoff valve on the described first via filter pipe; Described second passes by and is respectively arranged with second electromotive intake valve, second screen pack and the second electronic blowoff valve on the chimney filter road; Described first electromotive intake valve and second electromotive intake valve all are positioned at described water inlet pipe place, the described first electronic blowoff valve and the second electronic blowoff valve all are positioned at described blow-off pipe place, described first screen pack and second screen pack all are positioned at described tank body, and be connected with described tank body, the two-way filter pipe is run through respectively pass through tank body; The two ends of described tank body are respectively equipped with the screen pack conveying end, and namely the first screen pack conveying end and the second screen pack conveying end can directly take out screen pack from tank body, need not to move other pipelines again, are very easy to the maintenance to screen pack.
Further, described tank body is provided with pressure difference switch.
Further, be provided with Pressure gauge on described water inlet pipe and the outlet pipe, described water inlet pipe is provided with air bleeding valve.
Further, described full-automatic pair of net backwash filter also is provided with control system, and described electromotive intake valve, electronic blowoff valve and pressure difference switch all are electrically connected with this control system.
Operation principle of the present utility model is: water is entered by water inlet pipe, arrive screen pack, in filter process, screen pack builds up foul, the impurity in the water, form the impurity screening layer, because impurity layer is deposited in the outside of screen pack, therefore just formed a pressure reduction in the inside and outside both sides of screen pack.Carry out automatic backwash by pressure difference switch, also can set timing automatic backwash according to water quality.
Advantage of the present utility model is: utilize two net pressure reduction to carry out backwash, can irrigate the i.e. anti-cleaning automatically while irrigating, automaticity height continuously, treating capacity is big, can clean blowdown and uninterrupted the irrigation voluntarily, cleaning performance is good automatically, and application surface is extensive, and screen pack can directly take out, need not to move other pipelines, the save trouble and labor is very easy to the maintenance to screen pack again.
The utility model is described in further detail below in conjunction with drawings and Examples.
