Abstract
The utility model provides an advection oil separation sedimentation tank unpowered drainage device in sewage treatment, comprising a drainage casing, wherein float bowls are symmetrically arranged on front and back sides of the drainage casing; left and right ends of the drainage casing are respectively mounted, in a sliding manner, on a lifting guide support which is vertically and fixedly arranged in a water outlet tank of the sedimentation tank; an opening is formed at the top end of the drainage casing; a water discharging and distributing weir plate is fixedly arranged on the edge of the opening; a water outlet is formed at the bottom of the drainage casing and is connected with a water collecting pipe through a drainage hose; the water collecting pipe is located under the drainage casing and is connected with a tank water outlet at the bottom of the water discharging tank of the sedimentation tank; the tank water outlet is connected with a drainage pipeline outside the tank so as to be connected with an inferior sewage treatment facility; an electric valve is arranged on the drainage pipeline; upper and lower limiters are arranged on the lifting guide support; and the corresponding limiting switches are arranged on the drainage casing. The device can discharge water without power and does not need maintenance; the discharged water is always the clear liquid at the surface of the water discharging tank of the sedimentation tank, and the quality of the discharged water is good, so that the load of the inferior sewage treatment facility is alleviated.
Description
Technical field
The utility model relates to the water-freeing arrangement in a kind of WWT, especially the unpowered water-freeing arrangement of advection oil partiting precipitation pool in the WWT.
Background technology
Existing industrial sewage is handled the draining of one-level processing advection oil partiting precipitation pool and is all adopted the submersible pump draining, because power source expends and makes use cost big, the maintenance cost of submersible pump is also high.What submersible pump was got rid of is the water of advection oil partiting precipitation pool water-supplying chamber bottom, because submersible pump is the inhaling type draining, sucks the dirt that is deposited in the bottom easily and is discharged in the next stage treatment tank, load that can corresponding increase next stage treatment facility.
Summary of the invention
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of the utility model is to provide the unpowered water-freeing arrangement of advection oil partiting precipitation pool in a kind of WWT, and unpowered draining need not be safeguarded after disposable the adjusting, and does not almost have maintenance cost; And because the water of discharging is the clear liquid of advection oil partiting precipitation pool outlet sump upper surface all the time, its effluent quality is better than the water that submersible pump is discharged, and then has alleviated the load of next stage treatment facility.
In order to address the above problem, the utility model adopts following technical scheme: the unpowered water-freeing arrangement of advection oil partiting precipitation pool in the WWT, comprise drain box, and the front and back zygomorphy of drain box is provided with floating drum; The drain box right ends is slidingly mounted on respectively on the vertical up-down guiding trestle; The up-down guiding trestle is installed in the settling tank outlet sump;
Described drain box top end opening is fixed with water outlet cloth weir board on this edge of opening; The bottom of drain box is provided with at least one water port; Described water port is connected with a header through scupper hose, and this header is positioned at the below of drain box and is connected with the sink waste of settling tank outlet sump bottom; Said sink waste is connected with the outer drainage pipeline of settling tank outlet sump, and the other end of drainage pipeline connects the next stage sewage treatment facility; On the described drainage pipeline motorized valve is housed;
Described up-down guiding trestle is provided with drain box operation stroke is carried out spacing upper limit device, lower retainer; Drain box is provided with and upper limit device, the corresponding capable bit switch of lower retainer.
Further technical scheme as the utility model: in this WWT in the unpowered water-freeing arrangement of advection oil partiting precipitation pool, but being installed on the drain box of described water outlet cloth weir board up-down adjustment; But described floating drum also is being installed on the drain box of up-down adjustment.
The beneficial effect of the utility model is: this device not only can be realized unpowered draining, need not safeguard after disposable the adjusting, and does not almost have maintenance cost; And because the water of discharging is the clear liquid of advection oil partiting precipitation pool outlet sump upper surface all the time, its effluent quality is better than the water that submersible pump is discharged, and then has alleviated the load of next stage treatment facility, has also reduced cost of sewage disposal.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the vertical view of the utility model embodiment;
Among the figure: 1 upper limit device, 2 row bit switches, 3 floating drums, 4 water outlet cloth weir boards, 5 drain boxs, 6 floating drum setting devices, 7 scupper hoses, 8 headers, 9 motorized valves, 10 lower retainer, 11 up-down guiding trestles, 12 settling tank outlet sumies, 13 sink waste.
Embodiment
Like Fig. 1, shown in Figure 2; The unpowered water-freeing arrangement of advection oil partiting precipitation pool mainly comprises drain box 5 in this WWT; The right ends of drain box 5 is slidingly mounted on respectively on the vertical up-down guiding trestle 11, and up-down guiding trestle 11 is installed in the settling tank outlet sump 12.
Up-down guiding trestle 11 is provided with drain box 5 operation strokes is carried out spacing upper limit device 1, lower retainer 10.Drain box 5 is provided with the capable bit switch 2 corresponding with upper limit device 1, lower retainer 10.
The front and back zygomorphy of drain box 5 is provided with floating drum 6; But being installed on the drain box 5 of floating drum 6 up-down adjustment.Floating drum setting device 6 can adopt bar shaped mounting groove and tack bolt to cooperate and realize that also can adopt other structures, in mechanical field, those skilled in the art need not pay creative work and can realize, therefore no longer details.
The bottom of drain box 5 is provided with a plurality of water port; Each water port is connected with header 8 through a scupper hose 7.This header 8 is positioned at the below of drain box 5 and is connected with the sink waste 13 of settling tank outlet sump 12 bottoms.Sink waste 13 is connected with settling tank outlet sump 12 outer drainage pipelines, and the other end of drainage pipeline connects the next stage sewage treatment facility; Motorized valve 9 is housed on this drainage pipeline.
This device can adopt whole stainless materials to process when making, and increasing the service life does not influence effluent characteristics yet.
Its principle of work is following: in the drainage procedure, the liquid level in the settling tank outlet sump constantly descends, and drain box 5 also descends thereupon, touches row bit switch 2 until lower retainer 10 backs, closes motorized valve 9, accomplishes draining.When in settling tank outlet sump 12, going up water, along with liquid level rises, drain box 5 and then rises to regulation liquid level bit switch 2 arrival upper limit devices 1 at once together, waits for the instruction of draining next time, opens motorized valve 9, realizes draining once more.The upper limit device is set, also realize the warning of liquid level superelevation, and liquid level falls in draining.
