Abstract
The utility model relates to a filter equipment, in particular to a filter equipment with a replace-free filter element. The utility model comprises a shell, a tubular filter gauze, a filtered-water discharge valve, a waste water discharge valve, a pressure booster and pipelines. The tubular filter gauze is arranged inside the shell with an upper opening arranged on the upper part of the shell. A water-filling inlet is arranged on the upper part of the shell. A filtered-water discharge outlet is arranged on the lateral part of the shell and a wastewater discharge outlet is arranged on the lower part of the shell. The waster water discharge outlet is connected with the lower opening of the tubular filter gauze and the lower opening of the tubular filter gauze is connected with the waster water discharge valve. The pressure booster is arranged on the pipeline between the filtered-water discharge outlet and an inlet of the filtered-water discharge valve. The utility model does not need to replace the filter element frequently, which saves material and cost. The utility model is easy to maintain with good filter effect.
Description
(1) technical field
The utility model relates to a kind of filter, especially a kind of filter of exempting to change filtrate or filter element.
(2) background technology
Existing filter is of a great variety, for example contains the filter of bulk material (for example filter sand, cotton, paper, ware etc.) or wire netting, by the filter cylinder filter that bulk material is made, utilizes filters such as ultrafiltration, electrodialysis, electro-osmosis.Usually for example often replacing such as bulk material, filter membrane of its filter thing, cost is higher, use is inconvenient.
(3) summary of the invention
The utility model aims to provide a kind of exempt to change filter thing, good filtration effect, easy to use, filter that cost is low.
The utility model is provided with housing, tubular filter screen, filtered water discharge valve, sewage blow-down valve, pressing aid and pipeline.Tubular filter screen is arranged in the housing, and the upper shed of tubular filter screen is connected to housing inner chamber top.Establish water inlet on housing top, establish the filtered water discharge mouth at the housing sidepiece, establish Sewage outlet at housing bottom, Sewage outlet is taken over the under shed of shape filter screen, and the tubular filter screen under shed connects sewage blow-down valve.Pipeline between filtered water discharge mouth and the filtered water discharge valve inlet is provided with pressing aid.
Tubular filter screen can be tapered tubular, cylindrical shape, tubaeform etc., can adopt materials such as metal, plastics, fabric.Sealing ring is preferably established in junction at filter screen and housing, and the filtered water discharge mouth of housing is directly discharged in order to avoid water inlet is directly flowed through outside filter screen, also avoids filtered water directly to discharge from the Sewage outlet of housing.
Said filtered water discharge valve and sewage blow-down valve can adopt magnetic valve.
Said pressing aid can adopt is inverted closed container formula pressing aid, vapour-pressure type pressing aid, spring pressing aid etc.
During normal the use, open the filtered water discharge valve, close sewage blow-down valve, running water or other feed flows join the filter screen upper shed from the housing upper shed, compile drainage floss hole, pipeline, the filtered water discharge valve of the housing of flowing through through the water of strainer filtering, and simultaneously pressing aid is pressurizeed.When the time spent does not maybe need to clean filter screen, close the filtered water discharge valve, and open sewage blow-down valve, at this moment the pressure that produces of pressing aid makes the water of backflow constantly wash filter screen, dirt on the filter screen is dropped and discharges from sewage blow-down valve.Obviously, not only filtrate be needn't often change, material and cost saved, easy maintenance, and can remove contamination good filtration effect at any time.
(4) description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
(5) specific embodiment
As shown in Figure 1, the utility model is provided with housing 1, tubular filter screen 2, filtered water discharge valve 3, sewage blow-down valve 4, pressing aid 5 and pipeline 6.Tubular filter screen 2 is arranged in the housing 1, and the upper shed of tubular filter screen 2 is connected to housing 1 inner chamber top.Establish water inlet 11 on housing top, establish filtered water discharge mouth 12 at the housing sidepiece, establish Sewage outlet 13 at housing bottom, Sewage outlet 13 is taken over the under shed of shape filter screen 2, and the tubular filter screen under shed connects sewage blow-down valve 4.Pressing aid 5 is located on the pipeline 6 between filtered water discharge mouth 12 and filtered water discharge valve 3 inlets.
Said filtered water discharge valve and sewage blow-down valve can adopt magnetic valve, also can adopt the machinery valve of filtered water and sewage discharge checker.
Said pressing aid can adopt is inverted closed container formula pressing aid, vapour-pressure type pressing aid, spring pressing aid etc.
Wherein, pressing aid 5 can adopt is inverted closed container formula structure, when exhaust filtering water, hydraulic pressure produces certain pressure to the gas in the closed container formula pressing aid, when to be removed contamination, this pressure will make current that filter screen is produced certain impulse force, reach the purpose of removing the dirt on the filter screen.Pressing aid also can adopt the vapour-pressure type pressing aid, establishes gas injection port on the closed container, and gas-pressurized enters from gas injection port.Also can in container, establish spring system, so that to ducted water pressurization.
