Abstract
The utility model provides a slag discharge device for air floatation equipments, comprising an air floatation chamber, a slag scraping transmission device, a slag guidance board and a plurality of water outlet pipes, which is characterized in that the slag guidance board is connected with an inclined board at a lower part of the slag guidance board, an angle between the inclined board and the horizontal plane is 45 degrees to 60 degrees, an edge, which is positioned where is about 10 cm below a scum layer in the air floatation chamber, is formed by an upper margin of the inclined board and the slag guidance board, and a slag receiving tank is fixedly connected with the inclined board; a clearance is positioned between one end of the slag receiving tank and a pool wall of the air floatation chamber. The utility model has the advantages that the structure of the air floatation slag discharge device is improved, the slag receiving tank is added, the air floatation effect is obviously increased, the treated water contains little scum, the added amount of chemical can be reduced in the case of same water quality and the operation cost is lowered.
Description
Technical field
The utility model relates in the waste water treatment slag discharging device in the airfloat equipment technology, particularly airfloat equipment.
Background technology
In wastewater treatment engineering, often to use airfloat equipment, it holds out the water surface by the come-up effect that gas ducks in drink with suspended substance in the water, forms scum silica frost, with slag discharging device scum silica frost is discharged again, and water is purified.
General deslagging technique can be divided three classes: the slag that 1, overflows, and promptly rely on the rising of water level or scum silica frost to assemble the back top of the slag and raise and slag is overflowed, but the concentration of the slag that overflows is lower, the water yield runs off big, and is bad to tough scum silica frost slagging-off effect; 2, skimming only is used for the shallow pool air-floatation deslagging, and manufacturing cost is higher; 3, scrape slag, be a kind of Slagoff method that the most generally adopts on the airfloat equipment, but also exist obvious defects, promptly no matter dreg scraper adopts assorted petty mode to move, and all existing in the process of striking off scum silica frost may mutual extrusion and cause slag, and influences water quality.Because the too fast or scraper plate of scraper plate movement velocity inserts factors such as the slag blanket degree of depth when scraping slag, causes the broken and turbulent of scum silica frost.After introducing the use of slag-guiding plate, though the problems referred to above are made moderate progress, still also have the part scum silica frost to be squeezed out, fall into the water, in the process of its decline, just and pneumatically supportedly go out water and converge, scum silica frost is taken out of by water, influences pneumatically supported treatment effect.
Summary of the invention
The purpose of this utility model is to solve airfloat equipment in tapping process, prevents to cause the broken and turbulent of scum silica frost, improves pneumatically supported treatment effect.
The technical solution of the utility model provides a kind of slag discharging device of airfloat equipment, form by gas-floating chamber 1, slag scraping drive unit 6, slag-guiding plate 5, rising pipe 3, it is characterized in that below slag-guiding plate 5, connecting a swash plate 2 horizontal by 45 degree-60 degree angles, the upper limb of swash plate 2 and slag-guiding plate 5 form a seamed edge, this seamed edge is arranged in about 10cm under gas-floating chamber 1 scum layer, the slag receiving tank 4 that falls of fixedlying connected with it is arranged on swash plate 2, gapped between an end of the slag receiving tank 4 that falls and the pool wall of gas-floating chamber 1.
Effect of the present utility model is to have improved air supporting slag discharging device structure, has increased the slag receiving tank that falls, and air flotation effect is obviously improved, and the water of treated mistake is substantially free of scum silica frost, under same water quality situation, can reduce added amount of chemical, has reduced running cost.
Description of drawings
Fig. 1 is a right section synoptic diagram of the present utility model.
Fig. 2 is that K of the present utility model is to structural representation.
Embodiment
Reaching embodiment in conjunction with the accompanying drawings is described further.
As shown in Figure 1, 2, slag-guiding plate 5 is installed in gas-floating chamber 1, swash plate 2 of welding below slag-guiding plate 5 horizontal by 45 degree-60 degree angles, the upper limb of swash plate 2 and slag-guiding plate 5 form a seamed edge, this seamed edge is arranged in that about 10cm is advisable under gas-floating chamber 1 scum layer, and the slag receiving tank 4 that falls of fixedlying connected with it is arranged on swash plate 2, and the slag receiving tank 4 that falls can directly be welded on the swash plate 2 with steel plate, also can adopt the material of other material, connect with bolt and make.Fall and leave certain clearance between the pool wall of end of slag receiving tank 4 and gas-floating chamber 1, make slag to be derived smoothly.Wedgewise is made in the fall bottom of slag receiving tank 4, is to be unlikely to be obstructed in order to be beneficial to along the scum silica frost of leading on the swash plate 2.Connect a guide plate 7 in the bottom of the slag receiving tank 4 that falls, make its with the pool wall of gas-floating chamber 1 and swash plate 2 between be a similar piped passage, be convenient to be squeezed that broken scum silica frost is collected and the importing sludge hopper by scraper plate.
From Fig. 2 is that K finds out to view, the slag receiving tank 4 that falls is height of centers, low chevron shaped in both sides, the width and the degree of depth according to gas-floating chamber, general herringbone subtended angle α is advisable with 90 degree, its objective is in order to make the slag can be in the process that falls, in the sludge hopper below branchs both sides drop into, and can not taken away by the air supporting water outlet, avoided converging with the air supporting water outlet. midwayThereby, improved the deslagging quality, reduced running cost.
