Abstract

A water purifying device with the automatic backwash function comprises a filter element, pipelines and a foreign material storage area, which is characterized in that the water purifying device respectively connects the foreign material storage areas of two groups of filter tanks in parallel, and leaves two openings after the parallel connection, one opening is connected with draining pipes, and valves are respectively installed on the draining pipes, the other opening is connected with a water inlet of need-processing water through water inlet pipes of the needing-processing water, pure water buffer areas of the two groups of the filter tanks are respectively connected in parallel, and are connected after the parallel connection, a valve is installed on the pure water pipeline which is on the behind, and a valve is installed on the pure water outlet. The needing-processing water can be tap water or industrial waste-water or other waste-water. The water purifying device has simple structure and assembly and low use cost, the pure water outlet and the waste-water outlet are divided during washing the filter element, the filter element can be washed clean only by a little water, thereby, the water source is saved, and the water purifying device not only can be used for purifying domestic drinking water, but also can be used for processing other waste-water.

Description

A kind of purifier that can recoil automatically

One, technical field

The utility model relates to a kind of purifier of filter cleaning water.

Two, background technology

WSSD is classified the water crisis one of as human the most serious challenge that faces in following 10 years.The situation is tense for water environment, and the discharge of major pollutant amount is considerably beyond the water environmental self-purification ability.A large amount of rivers and lakes, the whole world disappear because of excessive water, and water pollutes and makes a lot of water sources to drink again, adds water resources management and is not good at, and global water crisis is very serious.On the other hand, owing to the water resource that can utilize does not again have to utilize, a large amount of wastes of water resource have been caused.

For above-mentioned reasons, some inventors have invented some water treatment facilities, are used for the purification of domestic water and the processing of industrial water.Particularly Drinking Water and Industrial Wastewater Treatment, there are some equipment to be employed, but because structural reason, after using a period of time, impurity such as the small suspension in the water and some small colloid things can be adsorbed onto on the filtering material, often equipment is very little with regard to not water outlet or water outlet after use a period of time, finally can't use.

The patent No. is: the inventor of 03284024.1 " the drinking water water purifier that has circle irrigation system ", this water purifier of design is equipped with the impurity storage area at the filtering tank two ends, but two ends are Inlet and outlet water all, use after a period of time, change the water inlet direction, the dirt that accumulates in the one end impurity storage area can be rinsed out, impurity can not adhered on the filtering material, to guarantee the operate as normal of water purifier.But this water purifier, though two ends are all flushable, sewage outlet and water purification delivery port are common, control valve can change the water inlet direction during use.Because delivery port is common,, sewage is rushed out, till flowing out clear water, so relatively waste water so when washing filter core, all need to discharge a certain amount of water at every turn.

Three, summary of the invention

The technical problems to be solved in the utility model is: design a kind of purifier that can recoil automatically, and this purifier, pure water inlet is what to separate with outlet of sewer, only needs a spot of water sewage can be rushed out, and has saved the water source.

The technical scheme that solution the utility model technical problem is taked is: the impurity storage area of two groups of filtering tanks is in parallel respectively, reserve two mouths after the parallel connection respectively, mouth sewage pipe that runs in, and at the blow-off pipe valve that is separately installed with waterborne, the water water inlet pipe that the another one mouth is handled through needs couples together and connects the water water inlet that needs processing, on the water water inlet pipe that each need be handled valve is installed all; The water purification buffering area of two groups of filtering tanks is in parallel respectively, and parallel connection is equipped with valve after the water purification pipeline is connected on a water purification pipeline of back, at pure water inlet valve is installed.The water that needs to handle can be running water or industrial wastewater or other waste water.

Good effect of the present utility model is: simple in structure, simple installation, use cost is low, filter core flushing process pure water inlet is what to separate with outlet of sewer, only need a spot of water filter core can be rinsed well, save the water source, not only can be used for purifying Drinking Water, also can be used to handle other waste water.

Four, description of drawings

External structure of the present utility model and pipeline connection diagram.

Five, the specific embodiment

Accompanying drawing is the embodiment that the utility model is used for handling industrial wastewater, first group of filtering tank is by two overanxious jar 21 and joint group, second group of filtering tank is made up of filtering tank 6, two overanxious jar 21 impurity storage areas 1 also are unified into a back mouth and connect recoil outlet of sewer 16 through sewage pipe 20, valve 17, and another mouthful connects industrial wastewater water inlet 12 through industrial wastewater water inlet pipe 2, valve 19; 3 one mouths in the impurity storage area of second group of filtering tank 6 connect recoil outlet of sewer 9 through sewage pipe 5, valve 8, and another mouthful connects industrial wastewater water inlet 12 through industrial wastewater water inlet pipe 4, valve 11; Water purification buffering area 18 parallel connections of two filtering tanks 21, the water purification buffering area 7 of filtering tank 6 is connected with two overanxious jar 21 water purification buffering area 18 of parallel connection through water purification outlet pipe 10, valve 13, and valve 14 is installed on pure water inlet 15.

Using method of the present utility model is: when normally using, with sewage pipe 20, valve 17 on 5,8 close, open industrial wastewater water inlet pipe 2, valve 19 on 4,11 and water purification outlet pipe 10, valve 13 on the

pure water inlet

15,14, industrial wastewater is squeezed into water inlet 12 with pump and is entered two groups of filtering tanks 21 respectively through valve 19 and valve 11,6, behind filter element filtering, the water purification of handling is from filtering tank 21, the water purification buffering area 16 of 6 bottoms, 7 through 15 outflows of water purification delivery port, can utilize again, impurity in the industrial wastewater is by filter element filtering, and is stored in impurity storage area 1 and 3.After using a period of time, close the valve 14 on the water purification delivery port 15, valve 19 on the industrial wastewater water inlet pipe 2, open the valve 11 on the industrial wastewater water inlet pipe 4, two sewage pipes 20, valve 17 on 5,8 and water purification outlet pipe 10 on valve 13, with pump with industrial wastewater through water inlet 12, valve 11 is squeezed into filtering tank 6, water purification oppositely enters its filter core through valve 13 from the water purification buffering area 16 of filtering tank 21 bottoms from the water purification buffering area 7 of filtering tank 6 bottoms behind filter element filtering, impurity storage area 1 to top recoils away the impurity in the impurity storage area again, and through sewage pipe 20, valve 17 is discharged from recoil outlet of sewer 16.

Recoil impurity in the overanxious jar impurity storage area, 6 top 3 according to said method, is adjusted corresponding valve and is got final product.
