Description
Technical field
The present invention relates to the oblique filter board type filter of a kind of water treatment, belong to water-treatment technology field.
Background technology
At present in water treatment field, traditional rapid filter is mainly adopted to water filtration, tank body pressure filtration and filler gravity filtration with no pressure, the filtrate of tank body pressure filtration often adopts quartz sand, anthracite and baton round etc., general employing single-stage is filtered, filter efficiency is not high, the appearance of fiber ball filter is in recent years the important breakthrough of traditional sand filtration technology, but the subject matter existed in the application of its fiber ball filter is: along with lasting use or the change of water quality, the deposition in filter in fibrous nodules is caused to increase gradually because recoil does not wash clean, make to filter rear deteriorating water quality and loss of flood peak increasing etc., to such an extent as to frequent shutdown of having to takes out filtrate cleaning by artificial.Therefore, obvious harmful effect is created to the normal running continuously of water treatment facilities, causes the filtration benefits of filter to reduce.
Summary of the invention
The present invention is directed to above problem, the oblique filter board type filter of a kind of water treatment is proposed, two-layer inclination filter plate has been installed, and on two-layer inclination filter plate, be provided with coarse media and the fine filtering material of classification, form the multi-segment structure be made up of end socket, filter cylinder, two-layer inclination filter plate, stable, backwashing manner is convenient, flexible.
Object of the present invention is achieved through the following technical solutions: the present invention includes: end socket, filter cylinder, coarse media, the first discharge gate, the first Butterworth Hatch, the second discharge gate, the second Butterworth Hatch, the first backwash floss hole, the first charging door, the second backwash floss hole, the first filter plate, the second charging door, fine filtering material, the second filter plate, inspection socket; It is characterized in that: described filter cylinder inside sets gradually tilted-putted first filter plate and the second filter plate from top to bottom, filter plate and horizontal line angle a are 20 ° ~ 60 °, and coarse media is provided with on the first filter plate, second filter plate is provided with fine filtering material, and the particle diameter of coarse media is 1.2 ~ 1.5 times of fine filtering material; Top bottom the sidewall of described filter cylinder and the first filter plate is provided with the first discharge gate, and the sidewall of filter cylinder and the top on the first filter plate top are provided with the first charging door, and above the first charging door, be provided with the first backwash floss hole; The sidewall of described filter cylinder and set gradually the first Butterworth Hatch and the second discharge gate between the first filter plate and the second filter plate from top to bottom, opposite side sets gradually the second backwash floss hole and the second charging door from top to bottom.
The upper end of described filter cylinder is provided with end socket, and the top of end socket is provided with water inlet pipe.
The bottom end socket of described filter cylinder is provided with outlet pipe.
Segmented two-stage filter operation principle of the present invention: after pending water reaches inflow requirement, the filtration through two-layer filtrate in filter cylinder is entered from water inlet pipe, first, pending water enters coarse media, the rate of filtration is 16 ~ 20m/h, water enters the fine filtering bed of material through the first filter plate, then enters bottom filter cylinder 4 after the fine filtering bed of material filters and discharges from outlet pipe.When cleaning and filtering resistance increases, stop water inlet, start backwashing procedures, backwashing water enters from the first backwash floss hole and the second backwash floss hole, also air water combined cleaning and individual layer cleaning respectively can be adopted, because filter plate and horizontal line angle a are 20 ° ~ 60 °, backwash water enters two-layer filtrate and filtrate forms angle, to the adsorption fouling suspension of filter material surface, there is shear action, be easy to cleaning, and washing time shortens than conventional filters, water after backwash is discharged from the first backwash floss hole and the second backwash floss hole respectively, complete the cleaning to filtrate, then filtration condition is entered.
The present invention has following advantage and beneficial effect: installed two-layer inclination filter plate, and on two-layer inclination filter plate, be provided with coarse media and the fine filtering material of classification, form the multi-segment structure be made up of end socket, filter cylinder, two-layer inclination filter plate, stable, backwashing manner is convenient, flexible, can adopt air water combined cleaning and individual layer cleaning respectively; Backwash water enters two-layer filtrate and filtrate forms angle, has shear action to the adsorption fouling suspension of filter material surface, be easy to cleaning, and washing time shortens than conventional filters.
