The doser is a medicine feeding chamber provided with a medicine feeding opening, the automatic dirt-removing filter which can automatically flush internal dirt by using water flow is provided with a water inlet and a water outlet. The side of the automatic dirt-removing filter is provided with a hand hole which is convenient for maintenance, the lower part is provided with a drain, and the medicine feeding chamber is connected with a water inlet pipe and a water outlet pipe. The middle parts of the water inlet pipe and the water outlet pipe are uniformly provided with stop valves. The utility model can both feed medicine and eliminate dirt, and filter and eliminate impurities by automatic flushing. The utility model is characterized in superior performance, and convenient use, and the utility model can be extensively suitable for hot water heating circulating systems, air conditioning water circulating systems and various cooling water circulation systems.
Description
The utility model relates to a kind of liquid filter that is used for removal of contamination.
In water supply piping system,,, strainer generally all is not set at present, in water supply line in case because the strainer inner product has impurity then non-easy cleaning so dirt and impurity are often arranged in the pipeline owing to containing impurity and water in the water to Corrosion of Pipeline.Sometimes be the water treatment agent that admixture is used for scale removal in water, but use inconvenience and can not handle impurity.
But the purpose of this utility model provides a kind of not only dosing scale removal, but also can filter and wash automatically despumation, superior performance, recirculated water dosing blowdown double purpose device easy to use.
The technical solution of the utility model is as follows: the utility model is to be formed by doser and automatic pollution discharge combination of filters, wherein doser is the dosing chamber that has dosing mouth, the automatic pollution discharge strainer that can utilize current to wash inner dirt automatically has water-in and water outlet at two ends, its side has the hand hole of easy access, its underpart is provided with blow-off pipe, be connected to water inlet pipe and rising pipe on the dosing chamber and connect water-in and water outlet respectively, be equipped with stopping valve at the middle part of this water inlet pipe and rising pipe.The dosing chamber does not communicate with the housing of automatic pollution discharge strainer but makes an integral body.
Automatic pollution discharge strainer of the present utility model is made up of housing, butterfly valve, cartridge filter and butterfly valve pilot lever, the housing two ends have water-in and water outlet, cartridge filter is arranged at the intravital water inlet of shell, cartridge filter is the cylinder that is covered with aperture, its inside is provided with the butterfly valve of control flow direction-changing and cartridge filter switch, and blow-off pipe is connected in the outlet of cartridge filter.End-of-the-pipe is provided with wash water valve.The butterfly valve pilot lever is installed on the housing of automatic pollution discharge strainer and with butterfly valve and links to each other, the switch of control butterfly valve.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.
Fig. 1 is a structural front view of the present utility model;
Fig. 2 is the A-A face sectional view of Fig. 1.
Fig. 1 reflects one-piece construction of the present utility model, and Fig. 2 then reflects the internal structure of automatic pollution discharge strainer 2.Water-in 8 of the present utility model and water outlet 9 are connected the water inlet pipe and the rising pipe of waterworks respectively, and water-in 8 and water outlet 9 are convenient to the circulation of water by the housing 10 that communicates.When carrying out the dosing processing, close the water intaking valve 4 and the outlet valve 5 in dosing chamber 1 earlier, open dosing mouth 3, medicament is put into dosing chamber 1, seal dosing mouth 3 then, open the water intaking valve 4 and the outlet valve 5 in dosing chamber again, then the circulating water flow of waterworks will be brought in the system by water-soluble medicament through dosing chamber 1.Added water treatment agent belongs to water soluble medicament, when circulating water flow by water-in 8 after water intaking valve 4 enters dosing chamber 1, medicament is dissolved in the water, enter in the circulating water system through outlet valve 5, the composition that the metal table is had strong avidity that is contained in the medicament reacts with the metal that contacts with water, thereby generate the meagre and tough and tensile molecular film of one deck on its surface, this film can prevent the generation of burning and galvanic corrosion; Medicament is soluble in water, just forms a kind of colloidal state negative ion, and suspended substance in the adsorbable water of this colloidal state negative ion and calcium ions and magnesium ions and form colloidal particle prevent fouling owing to the colloidal state negative ion has played the inhibition dissemination to the generation of carbonate deposit and deposition; When recirculated water reaches medicament solubleness, when producing the kieserohalosylvite precipitation and being condensed into the macromolecule floss, close water intaking valve 4 and outlet valve 5, circulating water flow is when automatic pollution discharge strainer 2, and suspended impurity all is left in the cartridge filter 12 in the water.Behind circulating water flow operation one-period, need carry out blowdown handles, butterfly valve 11 generally is to make it be in opened condition by butterfly valve pilot lever 13, water in the pipeline enters cartridge filter 12 by water-in 8, water flows out from water outlet 9 by the mesh on the cartridge filter 12, impurity is deposited on the cartridge filter 12 in the water, then may block the mesh on the cartridge filter 12, after the wash water valve of blow-off pipe 6 outlets is opened, discharge by cartridge filter 12 increases, flow velocity increases, and has got excited to be bonded at impurity on cartridge filter 12 tube walls, and impurity is swept away and discharges from blow-off pipe 6; And when butterfly valve 11 cuts out and opens wash water valve, then current are forced to entrance end, the butterfly valve 11 mesh outflow of part before by cartridge filter 12, enter cartridge filter 12 outsides, part water flows out from water outlet 9, another part water is side inflow cartridge filter 12 inside outside cartridge filter 12 latter half of again, cartridge filter 12 from carrying out counterflush outside to inside, is discharged from blow-off pipe 6 promptly from the cartridge filter 12 outside impurity that stick on the mesh that inwardly wash, and with impurity.And when this flushing still can not be with the contaminant removal in the cartridge filter, then need the Inlet and outlet water valve closes is opened hand hole end cap 7,, by hand hole cartridge filter 12 is rinsed well by artificial.
In sum, but both dosing scale removal of the utility model can be filtered again also auto-flushing despumation, and performance is excellent More, easy to use, easy for installation, have the advantages such as de-sludging, antiscale, antirust, anti-algae, anticorrosion, can prolong Service life of equipment, and realize economize on water, economizing on coal, economize on electricity, the utility model hot water circuit that is widely used in heating is System, air conditioner water circulating system and various cooling water recirculation system.
