Abstract
The utility model relates to a filter, comprising a casing and a filter cartridge. A water inlet, a water outlet, and a drain port are arranged on the casing, the space between the casing and the filter cartridge comprises a coarse filtering area and a fine filtering area which are divided, the water inlet is communicated with the coarse filtering area, the water outlet is communicated with the fine filtering area, the filter cartridge comprises a coarse filtering screen cartridge and a fine filtering screen cartridge which are mutually communicated, and filtering holes of the coarse filtering screen cartridge are larger than filtering holes of the fine filtering screen cartridge. The utility model filters liquid needing filtering twice, comprising a coarse filtration and a fine filtration. The utility model has the advantages of high quality of filtration, difficult clogging of the filter cartridge, and convenient cleaning and pollution discharging of the filter cartridge.
Description
The utility model relates to a kind of liquid filter that is used for removal of contamination.
In water supply piping systems such as air-conditioning, heating, water for industrial use, owing to containing impurity and water in the water to Corrosion of Pipeline, so dirt and impurity are often arranged in the pipeline.Adopted filter at present in some water supply line, these filters generally all adopt the once filter of filtration, and its shortcoming is:, impurity relatively poor when water quality more for a long time, cartridge filter is blocked soon, influences its operate as normal; The filter opening of cartridge filter is too little then easily blocked, and filter opening has reduced filter quality too greatly again, is difficult to realize fine filtering.
The purpose of this utility model is to provide the fine filter of a kind of filter quality height, difficult obstruction again, twice filtration of realization.
The technical solution of the utility model is as follows: the utility model comprises housing and cartridge filter, housing is provided with water inlet, delivery port and sewage draining exit, space between housing and cartridge filter comprises coarse filtration district and the thin filtering area that is separated, water inlet leads to the coarse filtration district, delivery port leads to thin filtering area, cartridge filter comprises two coarse filtration net tubes that link and fine filtering net tube, and the filter opening of coarse filtration net tube is greater than the filter opening of fine filtering net tube.
The utility model is provided with cleaning brush at fine filtering net tube inwall, and the power transmission shaft of this cleaning brush connects one and is located at the outer handle of housing, and when needing to clean, holding the handle rotation is the impurity of fine filtering net tube inwall capable of washing.Also can adopt handwheel, its effect is identical with handle.
The power transmission shaft of the cleaning brush of the utility model also links to each other with motor, with the rotation of driven by motor cleaning brush, finishes the cleaning of fine filtering net tube inwall automatically.
Be provided with sewage draining exit on the housing of the utility model, sewage draining exit communicates with the internal channel of fine filtering net tube on this, and sewage draining exit is provided with valve on this, and this valve can adopt hand valve or motor-driven valve.After cleaning brush had cleaned fine filtering net tube inwall, the impurity that is cleaned was discharged through last sewage draining exit.
But be provided with the hand hole of hand switch on the housing of the utility model, this hand hole communicates with the outer tunnel of coarse filtration net tube.Impurity on coarse filtration net tube is opened hand hole more for a long time, gets final product removal of contamination.Be provided with the down blow mouth on the housing of the utility model, this down blow mouth communicates with the outer tunnel of coarse filtration net tube, can discharge from the down blow mouth through the impurity that hand hole is removed.
During the utility model work, the water that needs to filter enters from water inlet earlier, carries out once thick filtration by coarse filtration net tube, and water enters cartridge filter inside, flows to fine filtering net tube again, carries out the fine filtering second time, and the water after twice filtration flows out from delivery port.
The utility model carries out twice filtration to the need filtered liquid, comprises a coarse filtration and a fine filtering, has both improved filter quality, and its cartridge filter is difficult for again stopping up, and the cleaning of cartridge filter, blowdown are all very convenient.
Further specify the utility model below in conjunction with accompanying drawing.
Fig. 1 is an internal structure cross section view of the present utility model.
Structure of the present utility model is shown in the embodiment of Fig. 1, housing 1 among Fig. 1 is cylindrical, housing 1 is provided with water inlet 11 and delivery port 12 taps into outlet pipe and flange respectively, it is arbitrarily angled that angle between water inlet pipe and the outlet pipe axis can be got 0 °, 90 °, 180 ° or other, makes installation and maintenance all very convenient.Also be provided with hand hole 8 and blowdown plug 10 on the housing 1, coarse filtration net tube 2 and fine filtering net tube 3 are housed in the housing 1; In the fine filtering net tube 3 on housing 1 top cleaning brush 4 is housed, the handle 7 that drives cleaning brush 4 rotations links by power transmission shaft 5 and cleaning brush, and the impurity that last sewage draining exit 6 is used for cleaning brush is washed is discharged, and last sewage draining exit 6 is provided with drain valve.Space between housing and the cartridge filter comprises coarse filtration district 13 and the thin filtering area 14 that is separated.
As shown in Figure 1, current flow into housing 1 bottom from water inlet 11, flow into coarse filtration net tube 2 inside from coarse filtration net tube 2 outsides through filter opening, coarse granule impurity is filtered off, accumulate in coarse filtration net tube 2 outsides, the drain valve of down blow mouth 9 is opened, these impurity can be emitted; And for the impurity that sticks on coarse filtration net tube 2 outer walls, can open hand hole 8 and clear up.Current after coarse filtration directly enter fine filtering net tube 3 inside, pass through the filtration of less filter opening again, outwards flow out, and flow out from delivery port 12; The fine impurity that filters out is for the second time then stayed in the fine filtering net tube 3 and on fine filtering net tube 3 inwalls.Turning handle 7 rotates cleaning brush 4, scrubs fine filtering net tube 3 inwalls, and opens the drain valve of sewage draining exit 6, and impurity is discharged.Open the blowdown plug 10 of housing 1 bottom, the impurity of staying coarse filtration net tube 2 and fine filtering net tube 3 inside can be discharged.
