Abstract
The utility model relates to a backwashing filtering drip irrigation device, which comprises a water inlet pipe, a water diversion pipe, a water collection pipe and a water outlet pipe, wherein, a filter is connected between the water diversion pipe and the water collection pipe, the bottom of the filter is provided with a sand discharge valve, the water inlet pipe and the water outlet pipe are respectively communicated with the middle parts of a water inlet regulation pipe and a water outlet regulation pipe, the water inlet regulation pipe and the water outlet regulation pipe are respectively provided with a control valve on pipelines of both sides of a position where the water inlet regulation pipe and the water outlet regulation pipe are communicated with the water inlet pipe and the water outlet pipe. In the utility model, the original single-row type filter is designed into a double-row filter which can operate alone, stop and teardown are not needed, backwashing sand cleaning and sundries cleaning can be carried out, and the operation efficiency of drip irrigation is enhanced.
Description
The utility model relates to the water-saving irrigation technique field, specifically is exactly that a kind of backwash principle of utilizing prevents the drip irrigation appliance that the drip irrigation filter element stops up.
Drip irrigation technique extensive use in agricultural production, the effect of the filter element in the drip irrigation appliance is extremely important.In the drip irrigation operation, because silt needs often to remove usually attached to the outer surface of filter element.Existing filter is generally single three-tube type filter; only adapt to and under the less water quality of silt content, use; when silt content is big; obstruction, liquid pressure drop increase will appear; need frequent shutdown dismounting filter element; clean or the replacing filter element, thereby cause the drip irrigation operating efficiency to reduce, influence normal drip irrigation job schedule.
In order to overcome above-mentioned weak point, the purpose of this utility model is to provide a kind of need not dismantle filter element, clean backwash filter drip irrigation appliance easily.
The purpose of this utility model is achieved in that it comprises water inlet pipe, distributive pipe, collector pipe and outlet pipe, be connected with filter between distributive pipe, the collector pipe, filter bottom is provided with sand excluding valve, its characteristics are to be provided with between water inlet pipe and the distributive pipe into water adjustable pipe, the centre of water inlet adjustable pipe links to each other with water inlet pipe and communicates with the distributive pipe of both sides, water inlet adjustable pipe two ends are respectively equipped with control valve, the water outlet adjustable pipe links to each other with the collector pipe of both sides respectively, communicate with outlet pipe one end in the middle of the water outlet adjustable pipe, its two ends are provided with control valve respectively.
For the ease of observing discharge pressure, the collector pipe of above-mentioned drip irrigation appliance is provided with the pressure monitor element.
In order to increase discharge, reduce resistance to water-flow, the filter core of the filter of above-mentioned drip irrigation appliance is provided with the staggered inlet opening of gathering.
Use this reality that novel backwash filter drip irrigation appliance is arranged, can carry out semi-automatic backwash filter, need not dismounting, easy to operate, quick.
Below in conjunction with accompanying drawing embodiment of the present utility model is done to describe:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 be among the utility model embodiment with left side filter attaching parts cutaway view;
Fig. 3 is the filter cartridge arrangement schematic diagram of the utility model embodiment.
See figures.1.and.2, embodiment of the present utility model comprises water inlet pipe 7, outlet pipe 15, water inlet adjustable pipe 3, water outlet adjustable pipe 13, distributive pipe (4,9), collector pipe (17,10), filter (2,8) and be located at filter (2,8) Di Bu sand excluding valve (1,11), water inlet pipe 7 one ends connect with the centre of water inlet adjustable pipe 3, water inlet adjustable pipe 3 respectively with the distributive pipe (4 of both sides, 9) link, on the water inlet adjustable pipe 3 of water inlet adjustable pipe 3 and the both sides, junction of water inlet pipe 7, be respectively equipped with control valve (5,6), distributive pipe (4,9), collector pipe (17,10) connect filter (2,8) between respectively, water outlet adjustable pipe 13 respectively with the collector pipe (17 of both sides, 10) link to each other, connect with outlet pipe 15 1 ends in the middle of the water outlet adjustable pipe 13, its both sides are provided with control valve (16,14) respectively.
For the ease of observing discharge pressure, the collector pipe of above-mentioned drip irrigation appliance (17,10) is provided with Pressure gauge 12.
With reference to Fig. 2, filter of the present utility model is by handle 21, cover plate 22, gland 23, drag hook 24, housing 25, filter core 26 compositions such as grade, gland 23 is by passing through drag hook 24, cover plate 22 and screw mandrel 29, make it and housing 25 end sealings, link to each other by short tube 27 between water collector 17 and the filter housings 25, link to each other by short tube 28 between water knockout drum 4 and the filter housings 25.
With reference to Fig. 2 and Fig. 3, in order to increase discharge, reduce resistance to water-flow, the staggered inlet opening 32 of gathering on the filter core 26 of the filter of above-mentioned drip irrigation appliance is covered with screen pack 31 on it.
See figures.1.and.2, the utility model is in the cascade filtration link of drip irrigation system in use.As when the washing and filtering device 2, control valve 5 is closed, open control valve 6,14,16, open sand excluding valve 1 simultaneously, by the current of water inlet pipe 7, water inlet adjustable pipe 3, filter 8, enter distributive pipe 17 again through short tube 27 outwards back flush in filter core 26 through water outlet adjustable pipe 13, make attached to the impurity on filter core 26 surfaces and discharge by sand excluding valve 1, finish flushing process, the most of supply field capillary that continues of the filtered water that is produced.The process of filter rinsed 8 is identical with said process.
Present embodiment is designed to double six tubular types that can work alone with former single three-tube type filter, makes it to have possessed not shut down recoil and wash down husky necessary condition, reduced pressure drop, again by the problem that four control valves have solved the reverse flow that backwash obtains is set.Compare with original single three pipes, efficient has improved 25%, and accommodation broad, water quality is poor slightly also can normally be used, and simple to operate, every dismounting of original equipment and cleaning once need to spend the time about one hour, often need to change filter screen, use the utility model to clean and to overhaul any row's well strainer at any time, convenient, fast.Therefore any row in double can work independently, and can not shut down a row is wherein carried out backwash or maintenance.
