Technical field
The present invention relates to a kind of sewage disposal device, especially a kind of left-falling stroke mud spoon that is used for air-floatation water purifier.
Background technology
In air-floatation water purifier, the flotation body constantly floats, and concentrates gradually near the body water surface of pond and forms scum silica frost (mud).Scum silica frost must in time be removed, so slag discharging device need be set.Up to now, domestic traditional rectangle air-floatation water purifier adopts chain type to push away the mud machine always---weir plate formula slag discharging device, see Fig. 1.
The principle of work of this slag discharging device is as follows:
End at water purifier rectangle pond body 18 is provided with sludge bucket 22 (overwhelming majority is arranged on an end of water purifier water port), and sludge bucket 22 separates by water body in weir plate 23 and the pond body 18.Chain type pushes away mud machine 19 and utilizes the some mud pushing plates that are fixed on two parallel chains that near the scum silica frost of the certain depth water surface is passed to sludge bucket 22 directions continuously.The height of weir plate 23 can be regulated.Can regulate the degree of depth that mud pushing plate gos deep into scum layer by the height of regulating weir plate 23, certainly, must regulate the elevation of water surface in the water purifier pond body 18 simultaneously, make it to be substantially equal to the height of weir plate 23, must make promptly that the last plane of the water surface and weir plate 23 is in the same plane substantially in the pond.The adjusting of water purifier pond body 18 median water level can realize by the valve amount of opening of regulating water purifier water-in 20, water outlet 21 simply, but water level is very unstable.Cause the unsettled reason of water level to be, the discharge capacity of trade effluent constantly changes often, so the water level in the water collecting basin constantly changes.The continuous variation of water collecting basin median water level causes that the sewage pump draught head that supplies water to water purifier constantly changes, and the discharge capacity of sewage pump constantly changes thereupon.Though the valve amount of opening of water purifier water inlet, water port has certain restraining effect to this variation, because the valve drag characteristic is non-linear, can not eliminate this variation fully, so the water level in the water purifier pond constantly changes, change is also bigger sometimes.
The continuous change of water purifier pond median water level can make the work of this slag discharging device very unstable: water level is crossed when hanging down, and scum silica frost can not in time be got rid of; And when water level was higher than on the weir plate plane, water can overflow enter sludge bucket, and the mud solid content of handling out is significantly reduced.
Basicly stable in order to guarantee water purifier pond median water level, the volume that need increase water collecting basin significantly is with the variation of the buffering water yield, the change of water collecting basin median water level is controlled in certain scope, so increased construction investment and floor space.
