Abstract
The utility model belongs to the field of water-saving irrigation and particularly relates to a trickle irrigation net type filter. The trickle irrigation net type filter capable of completing the cleaning of a filter element at work comprises an outer casing, a filter element, a water inlet pipe, a water outlet pipe and a blow-off pipe, wherein the water inlet pipe and the blow-off pipe are in the tangential position relative to the outer casing, the filter element is arranged at the center part inside the outer casing, the water inlet pipe and the blow-off pipe are respectively connected with the inner part of the outer casing at the two ends of the outer casing, the water outlet pipe is communicated with the inner part of the filter element from the center of the end part of the outer casing, the water inlet pipe and the blow-off pipe are arranged along the tangential direction of the outer casing, so that the filter element is not directly impacted by water and is prevented from being damaged by the impact force; in addition, the water flow entering a casing body along the tangential direction forms a rotational flow around the filter element, and the rotational flow has cleaning effect on the surface of the filter element; therefore, when the blow-off pipe is connected with the outside at work, the sewage is exhausted from the outer casing to complete the cleaning of the filter element.
Description
Technical field
The utility model belongs to the equipment field in the agricultural water-saving irrigation engineering, relates in particular to the drip irrigation well strainer.
Background technology
Well strainer is the critical piece of drip irrigation equipment, existing well strainer intake-outlet is over against its middle net formula filter core, filter core is yielding damage under the impact of water, needs frequent maintain and replace, in addition, when filter core stops up in the use, need stop water pump, open filter, take out filter core, it is manually cleaned, and these problems cause the drip irrigation equipment use cost to increase.
The utility model content
The utility model provides a kind of filter core to be difficult for being destroyed by water slug, simultaneously, can carry out the drip irrigation well strainer that filter core cleans under the not out-of-work situation of water pump.
The utility model comprises shell, filter core, water inlet pipe, outlet pipe, blow-off pipe, it is characterized in that described water inlet pipe and blow-off pipe are in tangent position with respect to shell, filter core is in the centre in the shell, water inlet pipe and blow-off pipe are connected in the two ends and the enclosure of shell respectively, and outlet pipe is from the center and the filter core internal switching of outer casing end.
The utility model beneficial effect is that water inlet pipe and blow-off pipe are along the shell tangential direction, make water directly not impact filter core, filter core is avoided the destruction of impulsive force, in addition, the current that enter housing along tangent line form the eddy flow around filter core in shell, and eddy flow has cleaning action to cartridge surface, like this, when blow-off pipe was with extraneous the connection in the work, sewage will be discharged from shell, finishes the cleaning to filter core.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
1. shells among the figure, 2. filter core, 3. water inlet pipe, 4 outlet pipes, 5. blow-off pipe.
The specific embodiment
With reference to accompanying drawing, the utility model comprises shell 1, filter core 2, water inlet pipe 3, outlet pipe 4, blow-off pipe 5, outside filter core 2, be provided with shell 1, filter core is in the centre of shell 1, water inlet pipe 3 and blow-off pipe 5 are tangent with respect to shell 1, and in the two ends and shell 1 internal switching of shell 1, outlet pipe 4 is from the center and filter core 2 internal switching of shell 1 end respectively.
Claims (3)
1. a drip irrigation well strainer comprises shell, filter core, water inlet pipe, outlet pipe, blow-off pipe, it is characterized in that water inlet pipe and blow-off pipe are in tangent position with respect to shell, and filter core is in the centre in the shell.
2. drip irrigation well strainer according to claim 1 is characterized in that described water inlet pipe and blow-off pipe connect at the two ends of shell and enclosure respectively.
3. drip irrigation well strainer according to claim 1 is characterized in that center and the filter core internal switching of described outlet pipe from outer casing end.
