Abstract
The utility model provides a water and air scrubbing-type mechanical filter, which comprises a filter main body, and a forward flushing water outlet pipeline and a back flushing lower sewage discharge pipeline which are arranged on the filter main body, wherein the filter main body is also provided with a back flushing water inlet pipeline and a back flushing upper sewage discharge pipeline which corresponds to the back flushing water inlet pipeline, wherein the back flushing water inlet pipeline is provided with a water injector air inlet pipeline. Large amount of air is sucked by utilizing the flow and the pressure of back flushing water in the back flushing water inlet pipeline through a hydraulic ejector on the water injector air inlet pipeline to make the water and the air mixed and enter the filter main body. The water and air scrubbing-type mechanical filter can achieve very good flushing effect in the back flushing process.
Description
Technical field
The utility model relates to a kind of water, gas scouring type mechanical filter.
Background technology
Mechanical filter utilizes one or more filter mediums, under certain pressure, make stoste pass through this medium and remove impurity, thereby reach the purpose of filtration, filler of dress is generally quartz sand, anthracite, particle porous pottery, manganese sand etc. in it, can select to use according to actual conditions.Mechanical filter mainly is to utilize filler to reduce turbidity in the water, holds back except that suspension, organic matter, colloidal particles, microorganism, chlorine in district's water and smells flavor and part heavy metal ion, and feedwater is purified.Mechanical filter is widely used in the water treatment procedure, is mainly used in to the water treatment turbidity removal, and the prime preliminary treatment of counter-infiltration and ion exchange softening desalting system also can be used for surface water, underground water except that silt.Influent turbidity requires less than 20 degree, and delivery turbidity can reach below 3 degree.Conventional mechanical filter needs the impurity on the cross section, organic matter, suspension, iron rust sewage etc. are carried out backwash after using certain hour, but directly the water flushing can't recoil clean.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of water, gas scouring type mechanical filter, can reach good developing result in backwash process.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: a kind of water, gas scouring type mechanical filter, comprise filter body, be located at normal outlet pipeline, square impact down blow water lines on the filter body, also be provided with sewer pipeline in backflushing water intake pipe road, the recoil corresponding with the backflushing water intake pipe road on the described filter body, described backflushing water intake pipe road is provided with the water sprayer air inlet pipeline.Utilize flow, the pressure of backwashing water in the backflushing water intake pipe road, and suck a large amount of air, make water, gas be mixed into filter body by the hydraulic ejector on the water sprayer air inlet pipeline.
As preferably, described filter body is provided with the gas exhaust piping corresponding with the water sprayer air inlet pipeline.
As preferably, be provided with return line between sewer pipeline and the water sprayer air inlet pipeline in the described recoil.Utilize return line to reflux repeatedly to circulate backwash, using water wisely.
Beneficial effect:
The utility model adopts technique scheme that a kind of water, gas scouring type mechanical filter are provided, utilize flow, the pressure of backwashing water in the backflushing water intake pipe road, and suck a large amount of air by the hydraulic ejector on the water sprayer air inlet pipeline, make water, gas be mixed into filter body, in backwash process, reached good developing result.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of water, gas scouring type mechanical filter, comprise filter body 1, be located at normal outlet pipeline 2, square impact down blow water lines 3 on the filter body 1, also be provided with sewer pipeline 5 in backflushing water intake pipe road 4, the recoil corresponding with backflushing water intake pipe road 4 on the described filter body 1, described backflushing water intake pipe road 4 is provided with water sprayer air inlet pipeline 6.Described filter body 1 is provided with the gas exhaust piping 7 corresponding with water sprayer air inlet pipeline 6.Be provided with return line 8 between sewer pipeline 5 and the water sprayer air inlet pipeline 6 in the described recoil.Identical with the standard machinery filter during normal the operation, normal outlet pipeline 2 is used to filtered water; When just washing, utilize 3 blowdowns of square impact down blow water lines; During backwash, open backflushing water intake pipe road 4, water sprayer air inlet pipeline 6, utilize flow, the pressure of backwashing water in the backflushing water intake pipe road 4, and suck a large amount of air by the hydraulic ejector on the water sprayer air inlet pipeline 6, make water, gas be mixed into filter body 1, sewage is gone up sewer pipeline 5 and is discharged from recoiling, gas is discharged from gas exhaust piping 7; When the sewage of discharging in finding last sewer pipeline 5 is comparatively clean, close sewer pipeline 5 in backflushing water intake pipe road 4, the recoil, open return line 8, utilize return line 8 backwash that repeatedly circulates that refluxes, open sewer pipeline 5 again, discharge from last sewer pipeline 5.This water, gas scouring type mechanical filter can reach than the high a lot of cleaning performance of standard machinery filter, generally we are controlled at 15 meters/hour with the backwash flow of inlet water, hydraulic ejector jet flow velocity 20 meter per seconds can reach comparatively desirable backwash effect like this.
