Description
Technical field
The utility model belongs to the improvement of water saving irrigation water filters such as sprinkling irrigation, drip irrigation, particularly improved water-saving irrigation water filter.
Background technology
Water-saving irrigation water filter commonly used at present, by a kind of combined type sandrock filter is secondary filter, its first order filter is for being equipped with certain thickness sandstone in filtering tank, constitute sandrock filter, the secondary filter granular membrane that the bottom of filtering tank is connecting by filtering out water pipe, granular membrane is for being installed with the filter screen that constitutes with plastics or metal material in tank body.Clean water after filter the second level enters water-saving irrigation system again.Can satisfy the water quality requirement of water-saving irrigation through the clean water of combined type sandrock filter filtration.But owing to connect by pipeline between the first order filter of this filter and the second level filter, increased the loss of flood peak, and the appearance and size of equipment is bigger, floor space is big.
Summary of the invention
The purpose of this utility model is to provide a kind of improved water-saving irrigation water filter, not only the clean water of Guo Lving can satisfy the water quality requirement of water-saving irrigation, and the contour structures compactness, and floor space is little, the loss of flood peak is little, and system is unaffected substantially when backwash.
The purpose of this utility model is achieved in that a kind of improved water-saving irrigation water filter, comprise sandrock filter and well strainer, in filtering tank, filtering tank is separated into filter chamber and strainer chamber by the horizonal base plate that is evenly equipped with through hole, in the filter chamber, the filter chamber evenly is separated at least 4 independently filter chambers, unit by vertical partition plate, on the uniform through hole of filter chamber's horizonal base plate, filter bowl is installed respectively, in each filter chamber, unit, loading the filtration layer of sand, in the capping of filter chamber, be provided with respectively and corresponding sand inlet in filter chamber, unit and water inlet straight tube, main water inlet tube is communicated with the water inlet straight tube by the tube connector that inlet valve is housed, the water inlet straight tube mouth of pipe that the backwash outlet pipe is equipped with sewage draining valve with top is cascaded, and in the bottom of strainer chamber outlet pipe is being set.
Main water inlet tube of the present utility model connects the water source, and its outlet pipe connects water-saving irrigation system.Close the into sewage draining valve on water straight tube top, open the inlet valve on the tube connector, water enters the filter chamber, unit from main water inlet tube respectively by tube connector and water inlet straight tube, filters through filtering layer of sand, after filtering through filter bowl, is pooled to strainer chamber again.Clean water through cascade filtration is imported water-saving irrigation system by outlet pipe again.
The utility model sandstone is filtered into one-level and filters, and filter bowl is filtered into cascade filtration, because filter bowl is installed in sandrock filter inside, not only compact conformation has reduced floor space, and has reduced the pipeline connection of I and II filter, has reduced the loss of flood peak.Because filtering tank of the present utility model evenly is separated at least 4 independently filter chambers, unit by uniform dividing plate with the filter chamber, each filter chamber, unit can work alone when backwash.When carrying out backwash, open the sewage draining valve on corresponding water inlet straight tube top in the filter chamber's capping of a certain unit, close the water intaking valve on its corresponding tube connector, from outlet pipe, feed press water and carry out backwash by the unit.The quartz sand that to pack into is rinsed well, after outlet pipe sewage draining exit water outlet subject to backwash becomes clearly, close the sewage draining valve on corresponding water inlet straight tube top in this filter chamber, unit capping, open the inlet valve on its corresponding tube connector, wash other filter chamber, unit with same operating procedure.In the process of backwash, can guarantee not interrupt to water-saving irrigation system water supply, make water-saving irrigation system unaffected substantially.
