A kind of filter device

Technical field

The utility model is related to technical field of sewage, more specifically, it relates to a kind of filter device.

Background technology

Sewage treatment process be exactly to city domestic sewage and industrial wastewater it is various it is economical, rationally, it is science, effective Process.Sewage disposal is widely used in building, agricultural, traffic, the energy, petrochemical industry, environmental protection, urban landscape, medical treatment, meal The every field such as drink.

Such as the Chinese patent that notification number is CN204841177U discloses a kind of sewage water filtration tank, including filter core, Sundries filters out roller, filtering tank, syringe pipe and sundries bucket, and the filtering pot bottom is equipped with stabilizer blade, and filtering tank is internally provided with miscellaneous Object filters out roller, and it is the closed cylindrical tube in one end that the sundries, which filters out roller, and sundries filters out roller blind end and passes through shaft Motor is connected, sundries filters out and is welded with helical blade on inner wall of rotary drum, and sundries filters out roller open end and is equipped with sundries bucket, sundries filter Except drums inside is equipped with sewage pipe, the sundries filters out roller upper horizontal and is provided with water pipe, and water pipe is equipped with several open The downward syringe pipe of mouth, sundries, which filters out, is equipped with filter core below roller, a kind of sewage water filtration tank realizes the quick of sewage Filtering, and sundries can be effectively excluded, filter efficiency is high, effect is good, is not susceptible to block, and reduces to greatest extent miscellaneous in sewage Object, maintenance workload is small, securely and reliably.

But its impurity particle in use is easy to be accumulated in filter core surface, it to a certain degree afterwards can be due to this accumulating A little impurity particles influence subsequent filter effect so that filtering tank is difficult to keep permanent good filter effect.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of filter device, has and reduce Magazine particle blocks filter layer, the advantages of to make filter layer keep good filter effect for a long time.

To achieve the above object, the utility model provides following technical solution：

A kind of filter device, including liquid storage tank and the filtering tank that is connected to by hose with the liquid storage tank, the filtering tank It is interior to be equipped with filter layer, and the filtering tank is separated into epicoele and cavity of resorption by the filter layer, the hose is connected to the cavity of resorption, The epicoele has vacuum pump by pipeline connection.

Using above-mentioned technical proposal, start vacuum pump, make to form continuous negative pressure or vacuum in filtering tank, water through hose into Enter cavity of resorption and enter epicoele by filter layer then up, is finally discharged from epicoele upper end, since water is moved upwards from lower end, in water Bulky grain can be moved downward due to self gravitation effect, it is not easy to be attached in filter layer, have and reduce magazine particle and block Filter layer, the advantages of to make filter layer keep good filter effect for a long time.

Further, it is equipped with buoyancy plate in the liquid storage tank, is fixedly connected with the buoyancy plate at the nozzle of the hose, and It can be moved up and down with the buoyancy plate.

Using above-mentioned technical proposal, buoyancy plate is swum in above liquid storage tank, and sewage is settled in liquid storage tank first, is stored up Liquid pool upper end is essentially supernatant liquor after settlement, and the water entered in filtering tank in this way has been subjected to preliminary filtering, contains Large granular impurity is less, further, reduces the case where blocking filter layer.

Further, the filter layer is both provided with the support plate with filter opening up and down, and the filtering is clamped in the support plate Layer.

Using above-mentioned technical proposal, support plate plays a supporting role to filter layer, reduce filter layer due to hydraulic pressure increase and It is deformed, filter layer is made more to stablize.

Further, it is provided with counterflow-preventing component in the support plate.

It using above-mentioned technical proposal, is moved by flow in this present embodiment, by the way that counterflow-preventing component is arranged, is prevented from bottom to top After only vacuum pump is shut down, filtered water flows back into cavity of resorption.

Further, the counterflow-preventing component is check valve.

Using above-mentioned technical proposal, check valve, which is fluid, to be flowed along water inlet, and water outlet medium can not but flow back, and prevented After only vacuum pump is shut down, filtered water flows back into cavity of resorption.

Further, the counterflow-preventing component includes being set in the support plate and heavy caliber end to set towards the epicoele The bellmouth set, motion stops compatible with the bellmouth, and for making the motion stops in the bellmouth Spring part.

Using above-mentioned technical proposal, when epicoele forms negative pressure, under atmospheric pressure by water under liquid storage tank indentation Chamber, and then the air of cavity of resorption or water top pressure motion stops, bellmouth is opened, and after vacuum pump is shut down, is returned in the elasticity of spring part Under multiple force effect, motion stops coordinate again with bellmouth, close bellmouth, and the water of intracavitary upper in this way will not flow back into cavity of resorption.

Further, the filter layer includes fiber PP cotton filter element, granular activated carbon filter core, the pressure set gradually from bottom to top Contracting active carbon filter core, hollow fiber ultrafiltration membrane and bacteriostatic activity filtration core.

Using above-mentioned technical proposal, which can filter out the particulate matter in water, adsorb the impurity in water, filter effect compared with It is good.

In conclusion the utility model has the advantages that：

1, start vacuum pump, make to form continuous negative pressure in filtering tank or vacuum, water enter cavity of resorption then up through hose Enter epicoele by filter layer, be finally discharged from epicoele upper end, since water is moved upwards from lower end, the bulky grain in water is due to certainly Body gravity can move downward, it is not easy to be attached in filter layer, have and reduce magazine particle blocking filter layer, to make Filtering layer keeps the advantages of good filter effect for a long time；

2, buoyancy plate is swum in above liquid storage tank, and sewage is settled in liquid storage tank first, and liquid storage tank upper end is essentially Supernatant liquor after settlement, the water entered in filtering tank in this way have been subjected to preliminary filtering, and the large granular impurity contained is It is less, further, reduce the case where blocking filter layer；

3, it is moved from bottom to top by flow in this present embodiment, by the way that counterflow-preventing component is arranged, prevents vacuum pump from shutting down Afterwards, filtered water flows back into cavity of resorption.
