Description of the drawings
Fig. 1 is the structural schematic diagram of the pretreatment system of water purification machine provided by the utility model.
Specific implementation mode
The utility model provides a kind of pretreatment system of water purification machine, for make the purpose of this utility model, technical solution and Effect is clearer, clear, and the utility model is further described in the embodiment that develops simultaneously referring to the drawings.It should be appreciated that Specific embodiment described herein only to explain the utility model, is not used to limit the utility model.
Referring to Fig. 1, a kind of pretreatment system of water purification machine, including settling box 1, coagulation bucket 2, flocculation bucket 3, filter 4, And cation switch 5;It is mixed that the first valve 6 and first is provided on water-supply-pipe between the settling box 1 and coagulation bucket 2 Clutch 7 contains coagulant in first mixer;The first blender 2.1 is provided on coagulation bucket, being provided with second on the bucket that flocculates stirs Machine 3.1 is mixed, the liquid in coagulation bucket is transported to by the first water pump 8 in flocculation bucket;Aqueduct between coagulation bucket and flocculation bucket On be provided with the second mixer 9, contain flocculant in the second mixer;Liquid in flocculation bucket is transported to sun by the second water pump 10 Ion interchange unit, the filter are arranged on the aqueduct between flocculation bucket and the second water pump;Cationic switch Water outlet be provided with the second valve 11.
Raw water is first precipitated in settling box, larger particulate matter is deposited to precipitation bottom of the barrel, the water on upper layer is in weight Force effect flows into coagulation bucket, and is tentatively mixed with coagulant when by the first mixer, and mixed liquor enters coagulation bucket It is middle to stir further mixing through the first blender, so that the particle for being difficult to precipitate in water is mutually polymerize and is formed colloid, water is by the It can tentatively mix with flocculant when two mixers, then be further mixed by the stirring of the second blender in the bucket that flocculates, to make Impurity between colloid and in water is combined into floccule body, and the volume of floccule body is larger, and can adsorb suspended matter, bacterium, Dissolved matter etc., floccule body will be filtered device and filter out, and water body has compared totally at this time, using cationic switch Most of remaining iron ion and aluminium ion in water removal is gone to obtain pretreated water, these pretreated waters feed to water purification machine into traveling The processing of one step can reduce the consume speed of water purification machine filter element, postpone its service life.As it can be seen that the pretreatment system can effectively drop The impurity content of low raw water.
Specifically, the settling box 1 includes exterior bowl 1.1, and the inner drum 1.2 being placed coaxially in exterior bowl, setting Cylindric mesh screen 1.3 in inner drum and water inlet pipe 1.4;Sieve is fixed on by several connecting rods in inner drum;Water inlet The side wall that pipe sequentially passes through exterior bowl, inner drum and mesh screen stretches into mesh screen, and the water outlet of water inlet pipe is set up;Inner drum Lower end offsets with exterior bowl bottom, and multiple interior bucket water outlets are uniformly provided on the side wall of its underpart.Water outlet of the raw water from water inlet pipe Mouth can play the progress first time deceleration on mesh screen after spraying, the water come out from mesh screen, which can be flushed on the inner wall of inner drum, carries out second From deceleration, water compared with low velocity eventually to flow downward and be flowed out from the interior bucket water outlet of inner drum lower part and be stored in exterior bowl In gap between inner drum, since water flows downward, be conducive to heavier particulate matter band to exterior bowl bottom, and flow velocity More slowly basic sediment will not be dug, therefore deposition efficiency is high.
Further, on the one hand the water outlet of the water inlet pipe 1.4 small big frustum-like shape under being reduces the initial velocity sprayed On the other hand degree is made water be sprayed the area for increasing itself and the direct collision of mesh screen with diffusion type, is conducive to more effectively reduce speed Degree.
In the present embodiment, the lower end of the inner drum 1.2 is up-small and down-big frustum-like shape, and the interior bucket water outlet setting exists On the side wall of the frusto-conical portion, to further decrease flow velocity of the water at this, deposition efficiency is improved.
Preferably, the bottom of said tub body 1.1 is taper, and lower end is provided with waste pipe 1.5, is provided on waste pipe Switching ball 1.6.On the one hand the cut-off region of water can be formed on the taper bottom, and water velocity is minimum at this, and it is heavy to be more advantageous to raising On the other hand shallow lake efficiency can be convenient for waste discharge.
In addition, the water outlet of exterior bowl 1.1 is arranged on the top of exterior bowl side wall.The only more clear water in upper layer could flow Go out.
Further, the coagulant box 7.1 for adding and storing coagulant is provided on first mixer 7;Institute State the flocculant box 9.1 being provided on the second mixer 9 for adding and storing flocculant.So as to adding for coagulant and flocculant Add.Herein, the first mixer and the second mixer are helical pipe.
In the present embodiment, the coagulant is one or more of ferric trichloride, bodied ferric sulfate, aluminium polychloride; The flocculant is polyacrylamide.
Specifically, the cation switch 5 is cation exchange column.Cation exchange column is by cation exchange tree Fat is loaded in a container, a kind of device for swapping, removing to the cation in circulation, is the prior art, herein not Its structure is described in detail.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to the protection of the utility model Range.
