The invention discloses a self-cleaning filter for a micro-irrigation system, and relates to a micro-irrigation technology. The purpose of the invention is to provide a self-cleaning filter for a micro-irrigation system with good filter material cleaning and thorough filtering effect. The gist of the technical solution of the present invention is that a self-cleaning filter for a micro-irrigation system includes a backwashing device for a water collection pipe, one-way bearings are arranged at both ends of the water collection pipe, and the circumferential surface of the water collection pipe is evenly distributed along the circumference and the axial direction. Filter cap, the pipe body at the lower part of the filter cap is sealed and connected with the wall of the water collection pipe, and its upper end is a cone. The cavity in the cone communicates with the tube hole and the inner cavity of the water collection pipe. The longitudinal slit communicates with the inner cavity of the cone. The invention is used for micro irrigation.
Description
Technical field:
The present invention relates to a kind of micro irrigation technology, particularly a kind of self-cleaning filter for micro-irrigation system.
Background technology:
Researched and developed slight irrigation sandrock filter by Australian scientist the seventies in last century, applied at world wide very soon.Micro irrigation technology had obtained extensive use under the film in Xinjiang of China area in recent years, and the research and development of the high-effect filter in the micro irrigation technology have been subjected to attention.The filter material of the filter that adopts is quartz sand or granite sand at present, and what its filtration relied on is the sieving actoion in space between sand grains and the impurity particle in the crown_interception interception water, thereby the impurity particle that will stop up douche easily removes.And suspended particulate is adsorbed by sand grain surface in the water, when the suspended impurity that adsorbs on the sand grain surface runs up to a certain degree, the resistance of filter is increased, filter effect descends, need this moment filtrate is cleaned, remove the impurity particle that filter material surface adheres to, recover the strainability of filter.The most frequently used cleaning way is that water or gas carry out backwash to filtrate, makes filtrate expansion rising and removes the impurity particle that adheres on the filter material surface by reverse flow or air-flow.Yet the problem that existing back purge system exists is, leave the dead angle during fixed collector pipe backwash, the sandstone filtrate can not be rinsed fully, and the filter effect of flushing after-filter can not reach fully and recover, main cause is, due to the skewness of backwash current.
Summary of the invention:
The purpose of this invention is to provide the self-cleaning filter for micro-irrigation system that a kind of filtrate cleans thorough good filtration effect.The present invention realizes that the technical scheme of goal of the invention is, a kind of self-cleaning filter for micro-irrigation system, comprise the collector pipe back purge system, it is characterized in that: the two ends at collector pipe are provided with unilateral bearing, collector pipe side face upper edge circumference and axially be evenly equipped with the filter cap, filter cap bottom is that the hole on a pipe and the tube wall that catchments is tightly connected, there is a cone upper end of pipe, be a conical cavity and pore and collector pipe inner chamber UNICOM in the cone, on the part cone wall of filter cap, be evenly equipped with vertical bar seam and cone cavity and be communicated with.Described part cone wall is that 180 °-270 ° cone wall is provided with the bar seam.The current that the present invention washes compared with the prior art do not have the dead angle, thus filtrate clean more thorough, the better remarkable advantage of the filter effect of filter.
Description of drawings:
Fig. 1 is the structural representation of the water filter back purge system of irrigation system of the present invention, and Fig. 2 is the A-A cutaway view of Fig. 1, and Fig. 3 is the front view of filter cap, and Fig. 4 is the B-B cutaway view of Fig. 3.
The specific embodiment:
In conjunction with above accompanying drawing the present invention is elaborated, the bottom is provided with collector pipe 2 in filter 1 housing, the unilateral bearing at its two ends places in the bearing block on the support 5, filter cap 4 with being evenly distributed in vertically on the outer wall of collector pipe, the structure of filter cap is, its underpart is that the hole on a pipe 7 and the tube wall that catchments is tightly connected, there is a cone 8 upper end of pipe, be that a conical cavity is communicated with pore and collector pipe inner chamber in the cone, have vertical bar seam 9 and be communicated with cone cavity on 180 ° of-270 ° of sidewalls of cone, the width of this seam is less than the particle diameter of filtrate (sand).The one end sealing of collector pipe, the other end is connected with slight irrigation pipe 6, and collector pipe is stacked with filter sand outward.
The principle of backwash of the present invention is, when needs clean filter, cut off the water supply of this filter, this moment, water entered from the water inlet tap 3 of filter, the filtrate that filters this filter through another filter carries out backwash, part current after the filtration oppositely clean filter sand along the slotted hole on the filter cap, owing to have only portion to separate slotted hole on the filter cap wall, the active force of current slowly rotates in filter housing by the moving collector pipe of filter hatband, make the filtrate in the filter obtain flushing, backwashing water flows out from sewage draining exit, thereby guarantees that filtrate cleans thoroughly, and the strainability of filter is restored.
Claims (2)
1, a kind of self-cleaning filter for micro-irrigation system, comprise the collector pipe back purge system, it is characterized in that: the two ends at collector pipe are provided with unilateral bearing, collector pipe side face upper edge circumference and axially be evenly equipped with the filter cap, filter cap bottom is that the hole on a pipe and the tube wall that catchments is tightly connected, there is a cone upper end of pipe, is a conical cavity and pore and collector pipe inner chamber UNICOM in the cone, is evenly equipped with vertical bar seam and cone cavity and is communicated with on the part cone wall of filter cap.
2, a kind of self-cleaning filter for micro-irrigation system as claimed in claim 1 is characterized in that: described part cone wall is that 180 °-270 ° cone wall is provided with the bar seam.
