Abstract
The utility model discloses an automatic back purge system, the casing of which is columnar. The automatic back purge system is provided with an inflow pipe and an outflow pipe, the inner chamber of the casing is divided into a coarse strainer chamber, a fine strainer chamber and a sewage drain chamber through clapboards, wherein the fine strainer chamber and the coarse strainer chamber are respectively provided with a fine strainer and a coarse strainer, a primary cleaning pipe and an accessory cleaning pipe; and filter suction nozzles staggering up and down are arranged on the primary cleaning pipe and the accessory cleaning pipe; a cleaning controller is arranged at the outside of the casing, a hydraulic motor is arranged in the sewage drain chamber, and the sewage drain chamber is connected with a wash water valve and a piston. The automatic back purge system of the utility model allows the primary cleaning pipe and the accessory cleaning pipe to be respectively provided with the filter suction nozzles, thus the backwashing efficiency is high and the filter effect is excellent. The automatic back purge system has the advantages of small volume, light weight and less occupied area, significantly reduces water and pressure loss during the backwashing, and effectively ensures water flow and water pressure of water supply for end users.
Description
Technical field
The utility model relates to a kind of water purification apparatus.
Background technology
The automatic backwash device be widely used in surface water, underground water, trade effluent and sanitary sewage desanding, degerming, remove filtration treatment such as algae and organic matter, in the prior art, mostly adopt single net tube filter or many candle filters etc., its shortcoming is that equipment volume is big, and scavenging period is long.
Summary of the invention
The purpose of this utility model is to provide a kind of volume little, can be directly installed on the water supply line, guarantees the automatic backwash device that the terminal use is just commonly used when cleaning.
The technical solution of the utility model is: the automatic backwash device, housing is a cylindrical shape, be provided with water inlet pipe and outlet pipe, the housing inner chamber is divided into straining chamber, smart filter chamber and blowdown chamber by dividing plate, in smart filter chamber and the straining chamber smart filter screen and coarse strainer are set respectively, main scavenge pipe and secondary scavenge pipe, the major and minor scavenge pipe filtration suction nozzle that is crisscross arranged up and down; Hull outside is provided with cleaning controller, the indoor hydraulic motor that is provided with of blowdown, and the blowdown chamber is connected with piston with blowoff valve.
The utility model automatic backwash device is respectively equipped with the filtration suction nozzle on the major and minor scavenge pipe, be convenient to clean thick, smart screen pack surface foul, good filtration effect; The utility model volume is little, in light weight, takes up an area of to lack, and water consumption and crushing when greatly having reduced anti-the cleaning have guaranteed terminal use's water supply effectively.
Description of drawings
Fig. 1 is the cutaway view of the utility model front view.
The specific embodiment
As shown in the figure, the automatic backwash device, housing is a cylindrical shape, be provided with water inlet pipe 11 and outlet pipe 13, the housing inner chamber is divided into straining chamber 1, smart filter chamber 2 and blowdown chamber 3 by dividing plate, coarse strainer 12 and smart filter screen 6 are set respectively in straining chamber and the smart filter chamber, main scavenge pipe 15 is set in the smart filter chamber, main scavenge pipe is crisscross arranged up and down and filters suction nozzle 7; Secondary scavenge pipe 5 is set in the straining chamber, is connected with main scavenge pipe, secondary scavenge pipe is provided with the filtration suction nozzle 4 with the identical setting of main scavenge pipe.The indoor hydraulic motor 14 that is provided with of blowdown, the blowdown chamber is connected with piston 10 with blowoff valve 9.Hull outside is provided with cleaning controller 8, cleaning controller control blowoff valve and piston.
When filtered water enters straining chamber from water inlet pipe, after filtering, coarse strainer enters the fine filtering chamber, after filtering, fie screen discharges by outlet pipe.After a period of time, on coarse strainer and fie screen, can pile up one deck foul gradually, just produce a pressure differential so screen pack is inside and outside.When this pressure reduction reached setting value, this device just began from flushing.Cleaning controller control blowoff valve and piston, water flows out through blowoff valve from hydraulic pressure horse chamber.When blowoff valve was opened, hydraulic motor was indoor, and a pressure differential is arranged between major and minor scavenge pipe and the screen pack, when water and foul process hydraulic motor, drive major and minor scavenge pipe and rotate, and piston also was driven and did axially-movable this moment, make suction nozzle will whole thick, thin screen pack surface cleaning totally.After foul washed on the filter screen, pressure reduction disappeared, and cleaning controller is closed blowoff valve, and piston back into the origin-location with scavenge pipe, begins next clean cycle.
