Description

Water decanter crest of weir purifier
Technical field
The utility model is related to water conservancy, environmental protection and technical field of sewage, net more particularly to a kind of water decanter crest of weir Water installations.
Background technology
China will carry out the engineerings such as large-scale river and lake dredging, reclaiming land around sea, expanding port construction every year, will produce a large amount of Mud.The muck soil that ship acquisition is inhaled by strand exists usually in the form of mud, and since its particle is smaller, sinking speed is slow, It is difficult to realize quick mud-water separation.Muddy mud such as drains into river, lake, marine without processing, will be to river, lake, sea original state water body Cause secondary pollution.To prevent secondary pollution, mainly takes at present and build sedimentation basin and add the means such as flocculation medicament.Tail water is arranged To sedimentation basin after a period of time natural sedimentation, then it is discharged into river, lake, marine.A certain amount of flocculation medicament is added in mud pit, is added Precipitate suspended particles rate in fast mud ensures draining water quality.Two methods can be used alone, and also can be used simultaneously.More than Though two methods in terms of reducing mud suspended matter value have certain effect, increase place build expense and adding of agent at This.Especially in river and lake dredging dehydrating and curing engineering, discharge outlet siltation increases underwater desilting quantities.
Water decanter is a kind of necessary mechanical drainage arrangement of intermittent activated sludge process (SBR) treated sewage.When liquid level height When degree is more than or equal to crest of weir elevation, water decanter starts to drain.Water decanter has the features such as continuous drainage, quantitative draining, stability is strong. The crest of weir of water decanter should lean on approximately level, can change with the variation of water level in pond.Water decanter is when transferring draining, to precipitating sludge Disturbance is smaller, can be drained by regulation flow.Water decanter when being drained or stopping drain operation, action is more steady, It is safe and reliable, and it is small to consume energy, service life is long.
Existing water decanter is typically provided rotatable pushing off the slag floating drum, and pushing off the slag floating drum energy partitive case keeps off suspension rubbish at crest of weir, But the tiny mud pellet being unable in lattice gear muddy water, cannot also reduce the SS values of water decanter draining water quality.
Invention content
The purpose of this utility model is that a kind of water decanter crest of weir purifier is overcome the deficiencies of the prior art and provide, it should Water decanter crest of weir purifier can solve the problems, such as that water decanter crest of weir runs mud, runs slag, reduce the SS values of water decanter draining water quality, simultaneously Also have many advantages, such as that easy to operate, processing cost is low, non-secondary pollution.
In order to realize that above-mentioned target, the utility model provide following technical solution:
A kind of water decanter crest of weir purifier, including cushion block, sprocket wheel, filter cloth or strainer, scraper, purifier frame, chain Item, rotary electric machine;
The purifier frame is mounted on outside water decanter crest of weir;
There are two the sprocket wheels, is separately mounted to the both ends of purifier lower portion, and the shaft of sprocket wheel is vertically arranged; The chain be it is enclosed, be wound on two sprocket wheels, and respectively with two sprocket engagements;The filter cloth or strainer and chain It is connected, and is covered on the lateral surface of chain;Meanwhile sprocket wheel is connected with rotary electric machine, sprocket wheel rotation drives chain, filter cloth Or strainer rotates synchronously;
The cushion block is mounted on purifier frame, and on the left of the water inlet end of water decanter crest of weir purifier;Institute It states scraper to be fixed on cushion block, and filter cloth or screen surface are close in the working end of scraper;
The cavity of water body filtration is collectively formed in the purifier frame, filter cloth or strainer, cushion block, scraper;
The rotating brush has several, is separately mounted on purifier frame, and is located on the outside of filter cloth or strainer, It is close to filter cloth or strainer;Meanwhile rotating brush is connected with rotary electric machine, and the rotation of its rotation direction and filter cloth or strainer Direction is opposite.
Further, water decanter crest of weir purifier further includes rotating brush, Cleaning pipes, pump;
The Cleaning pipes are arranged in the inside of purifier frame to convey cleaning solution, and its outlet is positioned at sprocket wheel Side;
The pump is connect mounted on the outside of purifier frame with Cleaning pipes, to provide power for cleaning solution.
In a preferred embodiment, it is fixedly connected between the filter cloth or strainer and chain.
Further, it is sealed connection between filter cloth or strainer and purifier frame;Specifically, purifier frame with Guiding groove is provided on the contact surface of filter cloth or strainer, filter cloth or strainer, which are located at, to be oriented in groove, and can be oriented to groove In move ahead, be oriented to groove on the one hand for fixing filter cloth or strainer, on the other hand play water proof purpose.
The water decanter crest of weir purifier is mounted on by purifier frame outside water decanter crest of weir.Water body is through straining water Enter water decanter crest of weir after the filtering of device crest of weir purifier, and then is discharged by water decanter drainpipe.
When liquid level is higher than water decanter crest of weir elevation, water body enters water decanter from water decanter crest of weir;Water decanter crest of weir Elevation can be adjusted by water decanter power plant.
Water decanter drainage pipeline refers into the drainage channel of the water body of water decanter crest of weir, and water decanter is according to flow depth displacement It intakes from crest of weir, is drained from tail portion.
In the present invention, the velocity of rotation of filter cloth or strainer and rotating brush can be adjusted by motor.Work as filter Cloth or strainer filtering hole plug, when strainability declines, regulation motor reduces the velocity of rotation of filter cloth or strainer, improves rotation hair Brush rotating speed, and pump is adjusted, cleaning fluid volume is increased, to ensure the water penetration of filter cloth or strainer.
Further, filter cloth or strainer can select the filter cloth or strainer of unlike material and aperture according to production requirement;Excellent In the embodiment of choosing, stainless steel filtering net or fiber filter cloth can be selected.When suspended matter value is relatively low in discharge standard, should select Aperture is smaller and has the filter cloth of certain filter depth.When suspended matter value is higher in discharge standard, it is larger that aperture may be selected Filter cloth or strainer.Cold district in winter, filter cloth or strainer because temperature is low harden when, 50 DEG C or so hot water can be used soft It.
In the present invention, when water decanter crest of weir purifier run time is longer, when damage of components, detachably into Row is replaced.
Compared with prior art, the beneficial effects of the utility model are:
Water decanter crest of weir purifier provided by the utility model can drain water decanter and be filtered, can relatively be better than The mud pellet and impurity in drain are filtered, solves the problems, such as that the prior art runs mud, leakage slag, reduces the SS values of water decanter draining water quality; The flow of the utility model design simultaneously is reasonable, and final the technical issues of solving meets the requirement of actual production.
