Abstract
The utility model relates to a combined water purifier, wherein, a total pressure dissolved air floatation unit is arranged at an upper layer of the combined water purifier, and a continuous backwashing movable sand filter unit is arranged at the lower layer of the combined water purifier. The combined water purifier can effectively reduce occupied area, improves the removal ratio of air floatation impurities, and solves the hardening problem of filter material.
Description
One, technical field
The utility model relates to a kind of combined type water purifying device in the purification of water quality engineering.
Two, background technology
Air supporting and filtration are the main treatment process that adopts in the purification of water quality engineering, have the air-floating apparatus of multiple pattern and hay tank to select for the user on the market, and most widely used is part dissolved air flotation device and the gravity filtration jar of stopping pollutent with filtrate.
More than device exists floor space bigger; The air supporting clearance is lower; Hay tank filtrate backwash decontamination effect improving is poor; Problem such as easily harden.
Three, summary of the invention
The purpose of this utility model is: air supporting and filtration are combined into one, and the upper strata is that total head air-dissolving air-float unit, lower floor are the moving sand filtering unit of continuous backwash; Can effectively reduce floor space; Structurally the total head air-dissolving air-float of Cai Yonging can improve removal of impurity, and the moving sand of the continuous backwash of employing filters, and can solve filtrate and harden.
The utility model is characterized in that: a upright tubular jar, the top is taper, being welded with dirt collecting bucket links to each other with blowdown main, central floor panel will be installed top and will be divided into air flotation cell, be welded with guide shell at the base plate middle part, reaction tube and water inlet pipe, epicone bucket inboard is provided with the air supporting level control valve, links to each other with screen casing on being welded under the device awl bucket through the air supporting rising pipe; Following awl bucket outlet is provided with ejector awl bucket in sand-ejecting tube and device and goes up the sand washing tube of installing and link to each other, and the sand washing tube bottom is welded with branch abrasive cone bucket, and the periphery is welded with interior dirt collecting bucket, and on awl struggled against during interior dirt collecting bucket was fixed on, its outlet linked to each other with blowdown main; On middle awl bucket, be welded with the water proof tube, filter out water pipe be welded on the tank body of awl bucket below, in the device, be that the sand filtering unit is moved in continuous backwash between the awl bucket down.

Five, embodiment
As shown in Figure 1, upright tubular jar, its diameter is relevant with the processing water yield, the upflow velocity of requirement in the c of dissolved air flotation chamber is that 2mm/ is about second, all sewage and gas are mixed into dissolved air water, in water inlet pipe (2) tangentially enters a chamber of guide shell (9) and reaction tube (8) composition, form eddy flow after the b chamber enters the c chamber, under the effect of micro bubble, impurity forms throw out and floats off from water body, be collected to epicone bucket (6) top, regularly open and close the impurity that air supporting level control valve (5) can gather the vertex of a cone and enter blowdown main (3) through dirt collecting bucket (4), the water after air supporting is handled flows into the screen casing (17) of bottom through air supporting rising pipe (7), and screen pipe opening is less than the minimum grain size of filter sand in the d chamber, the filter sand floor height goes out screen casing top 1~1.2m, separates abrasive cone bucket (16) end 0.3~0.5m.The ejector of bottom of device (20) is brought into the bottom filter sand in the sand washing tube (14) through sand-ejecting tube (19) by independent hydraulic spray, the filter sand friction that in the process of free-falling, repeatedly runs foul of each other, make attach its surperficial impurity separate and the come-up aggregation at middle awl bucket top, regularly open and close the valve that filters out on the water pipe, impurity is entered blowdown main (3) through interior dirt collecting bucket (12), the flow velocity of ejector nozzle and flow are guaranteeing to filter the water outlet water quality reaching standard, under the preceding topic that filter sand does not harden, should make backwash 1-2 time in 24 hours of whole filter sands, the filter sand of cleaning is through surface that minute abrasive cone bucket (16) cloth is fallen filter sand chamber d.
Claims (1)
1. combined type water purifying device; It is characterized in that: a upright tubular jar, the top is taper, is welded with dirt collecting bucket and links to each other with blowdown main; To install top by central floor panel and be divided into total head air-dissolving air-float unit, be welded with guide shell, reaction tube and water inlet pipe at the base plate middle part; Epicone bucket inboard is provided with the air supporting level control valve, links to each other with screen casing on being welded under the device awl bucket through the air supporting rising pipe; The outlet of following awl bucket is provided with ejector, and the sand washing tube of installing on the middle awl bucket of sand-ejecting tube and device links to each other, and the sand washing tube bottom is welded with branch abrasive cone bucket, and the periphery is welded with interior dirt collecting bucket, and on awl struggled against during interior dirt collecting bucket was fixed on, its outlet linked to each other with blowdown main; The middle bucket of boring is welded with the water proof tube, filters out water pipe and is welded on the middle tank body of boring below struggling against; In the device, down be that the sand filtering unit is moved in continuous backwash between the awl bucket.
