Abstract
The invention discloses an air-entrapping flusher of a micro-irrigation sandstone filter, comprising a filtering tank and a sandstone filter material filled in the filtering tank. A clapboard of a header tank is arranged below the sandstone filter material at the bottom of the filtering tank. A filter cap is arranged on the clapboard of the header tank and two air washing rings are arranged in the periphery and the middle of the filter cap. Air holes are evenly distributed at the up direction of the air washing rings in an interlaced way. The two air washing rings are connected with an air inlet pipe that runs through upwards along the inner wall of a tank body from a sand feeding port in a seal way and is communicated with an air compressor. The invention utilizes the combined action of water and air to cause a whole filter material layer in the tank body to produce the strong stirring, which can effectively wash impurities adhering to the sandstone cleanly with the action of impact of air and water flow and friction force caused by the collision of sandstones. With convenient operation and good backwashing effect, the invention saves the cleaning water used for washing.
Description
Technical field:
The present invention relates to field irrigation, particularly a kind of easy to operate, saving flushing clean water and manageable micro-irrigation sandrock filter aqueous vapor flusher simultaneously.
Background technology:
Slight irrigation is a kind of irrigation technique of water-saving in the world today, the slight irrigation filter is the equipment of most critical in this system, filter its sandstone filter material layer in use for some time will gather a certain amount of impurity, after impurity is accumulated to a certain degree, just must carry out backwash to it.Present back purge system mainly is to realize to consume a large amount of clean water, the problem one that exists is that to rinse out the impurity power consumption, the water consumption that adhere on the sandstone fully big, the 2nd, some filtering material particles of filtering layer bottom can't wash fully, the impurities accumulation of its inside deposition, these impurity are easy to enter irrigation system and stop up douche, cause irrigation system to scrap and destroy, influence normal irrigation.
Summary of the invention:
It is good to the objective of the invention is to design a kind of developing result, and micro-irrigation sandrock filter aqueous vapor easy to operate, as to save cleaning water is flusher simultaneously.
Technical solution of the present invention is finished as follows, it includes the sandstone filtrate of a filtering tank and interior dress thereof, it is characterized in that: below the sandstone filtrate of filtering tank bottom, a header tank dividing plate is installed, the uniform filter cap that is equipped with on the header tank dividing plate, on the header tank dividing plate in the middle of peripheral and peripheral filter cap of periphery filter cap and the center filter cap, be separately installed with a gas flushing circle, the staggered pore that is evenly equipped with the band non-return valve respectively of direction on two gas flushing circles, two gas flushing circles are connected on the air inlet pipe, and air inlet pipe upwards seals to pass from dress sand mouth along inner tank wall and is communicated with an air compressor machine.The present invention makes the strong stirring of whole filter material layer generation in the tank body with aqueous vapor acting in conjunction simultaneously, can be effectively the impurity that adheres on the sandstone be rinsed well under the effect of the impact of gas, current and sandstone collision friction power, it is easy to operate, saves flushing and uses clean water, and backwash effect is good.
Description of drawings:
Fig. 1 is a structural representation of the present invention; Fig. 2 is the side view of Fig. 1; Fig. 3 is the installation allocation plan of gas flushing circle of the present invention and filter cap; Fig. 4 is an operation principle schematic diagram of the present invention.
The specific embodiment:
The present invention is equipped with a header tank dividing plate 5 below filtering tank 2 bottom sandstone filtrates 1, on the header tank dividing plate, be evenly equipped with filter cap 3 and two gas flushing circles 7 and 23 according to the tank body size, two gas flushing circles are fixed on the header tank dividing plate with fixing card 24, simultaneously on the header tank dividing plate, be equipped with the hole that differs in size, be used for installing filter cap and fixed air flushing circle.The staggered pore 4 that is provided with uniform band non-return valve of direction on two gas flushing circles, two gas flushing circles connect with an air inlet pipe 18, air inlet pipe upwards seals from dress sand mouth 15 along inner tank wall and passes, link to each other with appendix 14 on the air compressor machine 11 by plug 17 and rubber end socket 16, valve 12 and air gauge 13 are installed on the air compressor machine appendix.In order to guarantee that air inlet pipe is close to inner tank wall and straight, fixing with fixing card 22 at air inlet pipe bottom and header tank dividing plate connecting place, the exit, top is fixing with plug 17 and rubber end socket 16.Water supply installation 10 is connected on the filtering tank bottom plug 6 by feed pipe, and water supply valve 9 and flowmeter 8 are installed on the feed pipe.Outwards be communicated with outlet pipe 20 at the tank body top by plug 19, water supply valve 21 is installed on outlet pipe.
Operation principle of the present invention as shown in Figure 4, the air compressor machine air-flow acts on filtering tank bottom filter cap sandstone filtrate on every side by the ejection of the pore on the gas flushing circle, current enter the filter cap by the header tank dividing plate, act on top sandstone filtrate by the ejection of filter seam, the acting in conjunction simultaneously of air-flow and current makes the impurity and the impurity between the slit that adhere on the sandstone filtrate in the filtering tank clean by cleaning down in whole filtering layer.During backwash, at first open flowing water Valve, open water supply installation, regulate institute's water requirement by flowmeter.Open air valve again and start air compressor machine, transferred air gauge to regulate required air pressure.The backwash simultaneously of beginning air water, wash in the whole at the beginning filtering layer and will produce strong stirring and circulation effect, air-flow has increased the frictional force between filtering material particle, make that the perturbation action of filtrate strengthens around the filter cap, when crowded mutually filling the between filtrate and the frictional force that produces and air-flow rise and under the acting in conjunction of the frictional force between filtering material particle, impurity that adheres on the filtrate and pollutant can be rinsed away in a short period of time.After the process flushing of certain hour, by determining water turbidity, backwash finishes when reaching requirement, closes air compressor machine and water supply installation, and whole flushing process finishes.Adopt air water shared backwash simultaneously to make backwash with the obvious advantage at aspects such as developing result, minimizing washing time and reduction flushing water consumptions, it is very fast that delivery turbidity descends, and single water backwashing delivery turbidity descends slowly.Aspect water loss, the water consumption of single water backwashing greatly reduces cleaning water greater than air water backwash simultaneously.
