Abstract
The invention provides a filter. A filtering layer is arranged in a main body of the filter, and a water inlet pipe is arranged above one side of the filtering layer. The water inlet pipe is communicated with a sand lifting pipe towards the lateral lower portion of the water inlet pipe, a sand-water separator is arranged on the upper portion of the sand lifting pipe, and the lower end of the sand lifting pipe is provided with a water distributor. One side of the sand-water separator, which turns the back to the water inlet pipe, is provided with a water outlet pipe and a blowdown pipe, an air-lift pump inlet is positioned below the water distributor, and the joint of the air-lift pump inlet and the water distributor is provided with a flow guide sand hopper. The filter is simple in structure and convenient to maintain, the process treatment efficiency is improved by 50%, the effect is stable, and the running cost is lowered.
Description
Technical field
The present invention relates to a kind of filter, be specifically related to a kind of continuous dynamic filter.
Background technology
In water treatment and purification technique, traditional filter is advection filtering tower type, above-mentioned filter
Backwash efficiency is low, causes backwash water amount to increase, and backwashing period is long, adds operation
With management cost, in addition, above-mentioned filtration device structure is the most complex, and later maintenance is protected
Support and more bother.
Summary of the invention
For solving above-mentioned technical problem, the invention provides a kind of new filter, its structure letter
Single, safeguard and overhaul conveniently, PROCESS FOR TREATMENT efficiency increase by 50%, effect stability, operating cost
Reduce.
A kind of filter, the body interior of this filter is provided with filtering layer, and side is arranged over into water
Pipe；This water inlet pipe connects a sand extraction tube towards its side-lower, and described sand extraction tube is arranged over a sand
Water separator, lower end is provided with a water-locator；The one of the most described water inlet pipe of described grit water separator
Side is provided with an outlet pipe and a blow-off pipe, is provided with an air lift pump entrance, institute below described water-locator
The junction stating air lift pump entrance and water-locator is provided with a water conservancy diversion sand bucket.
The invention provides a kind of new filter, its simple in construction, safeguard and overhaul conveniently,
PROCESS FOR TREATMENT efficiency increases by 50%, and effect stability, operating cost reduces.
Accompanying drawing explanation
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below
The accompanying drawing used required in embodiment or description of the prior art will be briefly described.
Fig. 1 is the structural representation of a kind of filter disclosed in the embodiment of the present invention.
1, filtering layer 2, water inlet pipe 3, sand extraction tube 4, grit water separator 5, water-locator
6, outlet pipe 7, blow-off pipe 8, air lift pump entrance 9, water conservancy diversion sand bucket
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes.
As it is shown in figure 1, a kind of filter, the body interior of this filter is provided with filtering layer 1, filter
Layer 1 built-in filtrate, side is arranged over water inlet pipe 2；This water inlet pipe 2 is towards its side-lower even
A logical sand extraction tube 3, described sand extraction tube 3 is arranged over a grit water separator 4, and lower end is provided with one
Water-locator 5；The side of the described the most described water inlet pipe of grit water separator 42 is provided with an outlet pipe
6 and a blow-off pipe 7, it is provided with an air lift pump entrance 8, described air lift pump below described water-locator 5
Entrance 8 is provided with a water conservancy diversion sand bucket 9 with the junction of water-locator 5.
The present invention mainly includes following two flow process when actually used:
Filter process: the former water after biochemical treatment or dosing coagulant, is entered by water inlet pipe 2
Uniformly cyclone water distributor 5, current are played energy dissipating effect, can make current by uniform cyclone water distributor 5
Stably enter filtering layer 1.The pollutant such as the float in former water are from bottom to top by filtering layer 1
During, dammed to get off by filtrate, filter the water outlet being raised to grit water separator 4 top waterborne
Downflow weir, water flow stationary ground enters downflow weir, through outlet pipe 6 outflow filter, filter type
For upward flow filtration, the steady safety of whole filter process.
Backwash process: in the centrally disposed air sand extraction pipe 3 of filter, air sand extraction pipe 3 straight cutting mistake
Bottom filter, when compressed air is passed through by air lift pump entrance 8, formed negative in filter bottom
Pressure, drives the dirty sand of filter bottom together to rise by gas stripping, and the dirty sand of bottom is from sky
Rising to grit water separator 4 bottom air stripping sandpipe 3, sand grains enters integral type sand moisture with current
From device 4.Sand grains, in backwash lifting process, is constantly subjected between the agitation of gas, sand grains
Friction and the shearing force of current, make the same separated from contaminants of sand grains, washes out with recoil filtering water outlet
The flushing water one in air stripping water grit water separator 4 under the effect of water water-head, in sand extraction tube 3
Discharge with from blow-off pipe 7.Under gravity, the filtrate cleaned returns to filter through water conservancy diversion sand hopper
Layer 1, completes filtrate wash cycles process inside filter tank.
The invention provides a kind of new filter, its simple in construction, safeguard and overhaul conveniently,
PROCESS FOR TREATMENT efficiency increases by 50%, and effect stability, operating cost reduces.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
The amendment made within bright spirit and converting on an equal basis, all should fall protection scope of the present invention it
In.
