Air supporting machine in the utility model is by at 200～300mm place, distance scum layer bottom one deck 5-20 purpose stainless steel wire filter screen being set, force the slag body to pass through filter screen by the buoyancy lift of slag body, bubble in the scum silica frost is pulled open by silk screen, thereby reduce the water content in the scum silica frost.
Description of drawings
Fig. 1 is the structural representation of air supporting machine in the utility model;
Fig. 2 be in the utility model the air supporting machine partly cut open schematic diagram;
Fig. 3 is the enlarged diagram of the dross dehydration of part shown in I device among Fig. 1.
The specific embodiment
The specific embodiment of the utility model is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, air supporting machine in the utility model comprises a housing 10, be provided with water distributing area 11, reaction zone 12, Disengagement zone 13, premium on currency district 14 and exhalant region 15 in these housing 10 inside, wherein 13 top is provided with Slag Scraping Device 16 in the Disengagement zone, and 13 bottom is provided with sludge discharging area 17 in the Disengagement zone.The course of work of this air supporting machine is with the sewage input water distributing area 11 after handling (not shown) through medicine system, tubular reactor, with mix by the dissolved air water that enters water distributing area 11 behind the molten gas of pressure air-dissolving device, and enter reaction zone 12, wadding grain in the sewage is sticked on the minute bubbles, 13 separation through the Disengagement zone again, make wadding agglomerate tabling in the sewage in the Disengagement zone 13 top, and relatively clean water enters exhalant region 15 from premium on currency district 14, and by pool 15 outputs, the simultaneously relatively large grains of sand are by sludge discharging area 17 outputs.
Because the scum layer thickness on air supporting machine top is generally 30～80mm, the zone between 13 tops, scum layer bottom to Disengagement zone is that scum silica frost forms, the district of growing up.More up the scum silica frost floc sedimentation is just big more in this zone.Therefore the air supporting machine in the utility model is provided with a dross dehydration device apart from 200～300mm place, scum layer bottom below the top of Disengagement zone 13, Slag Scraping Device 16, this dross dehydration device includes bracing frame and filter screen 20, wherein the height of filter screen 20 settings is advisable with distance slag blanket bottom 200～300mm, causes filter screen to stop up owing to the scum silica frost floc sedimentation is excessive because of too high meeting is set; Too low meeting is set makes the scum silica frost floc sedimentation be difficult to form or be difficult to grow up owing to destroy bubble too early.
Bracing frame in the dross dehydration device includes horizontal shore 18 and vertical support frame 19, as depicted in figs. 1 and 2, horizontal shore 18 and vertical support frame 19 removably are fixed on the inwall of air supporting engine housing 10 by connector (as screw, bolt, nut etc.), and can be with respect to housing 10 inwall adjustment height, so that the dross dehydration device is positioned at the optimum position apart from scum layer.Vertical support frame 19 is to constitute after the steel plate bar bending of 200mm by width; Horizontal shore 18 is made of the angle steel that is welded in 19 on two vertical support framves, and the last plane of angle steel should be concordant with the last plane of vertical support frame 19.
Because the scum silica frost face of air supporting machine is bigger, so filter screen is divided into some (also can be one).As shown in Figure 3, every filter screen 20 is made up of angle steel screen frame 21, stainless steel cloth 22, flat steel bar 23 and rivet 24, around the steel wire 22 with flat steel bar 23 rolling-in a few, angle steel screen frame 21 and flat steel bar 23 cooperate the punching back with rivet 24 stainless steel cloth 22 and flat steel bar 23 to be fastened on the angle steel screen frame 21.Around the angle steel screen frame 21 with horizontal shore 18 and vertical support 19 match-drill, with the bolt 26 anti-drill hole that are welded in horizontal shore 18 and vertical support frame 19, and every filter screen 20 is separately fixed on horizontal shore 18 and the vertical support frame 19 after the boring with wing nut 25.
In addition, the mesh of the stainless steel cloth that uses in the utility model is advisable with 5～20 orders, decides on oil content, viscosity, the solid impurity content of sewage.
In sum, air supporting machine in the utility model is by one deck 5-20 purpose stainless steel wire filter screen is set in appropriate location, bottom, scum silica frost district, force the slag body to pass through filter screen by the buoyancy lift of scum silica frost, bubble is pulled open by silk screen, thereby the moisture content in the reduction scum silica frost is for the subsequent treatment of scum silica frost provides advantageous conditions.
