Description
Technical Field
The utility model relates to a sewage treatment field, in particular to air supporting pond mud regulation and control structure.
Background
The pressurized air floatation is a process in sewage treatment, the working principle of the pressurized air floatation is that sewage passes through an aeration section in the rising process, flocs and suspended matters are fully mixed and contacted with micro bubbles, and because of the density difference between a gas-solid mixture and liquid, a vertical upward buoyancy is generated to bring the suspended solid matters to the water surface, so that the pressurized air floatation is particularly suitable for solid-liquid separation of fine particles and loose flocs.
The air supporting pond is as the place of pressurization air supporting, produces the thickness of not considering upper sludge easily in mud clearance process, and is unclean to the clearance of mud, perhaps upper sludge is thinner, causes the mud water content that gets into subsequent mud compression pond big, reduces work efficiency.
SUMMERY OF THE UTILITY MODEL
The utility model provides a solve above-mentioned problem, provide an air supporting pond mud regulation and control structure, through the regulation to the delivery port water yield, adjust the liquid level in the air supporting pond in real time, effectually prevent that too much entering of sewage from removing the cinder notch, reduce the mud moisture content, can effectively improve work efficiency.
In order to achieve the above purpose, the utility model adopts the technical scheme that: a sludge regulation and control structure of an air floatation tank comprises the air floatation tank, wherein a deslagging plate is arranged on the air floatation tank in a back-and-forth moving mode, the deslagging plate scrapes sludge into a slag discharging groove on the air floatation tank, an overflow weir is further arranged on the tank wall of the air floatation tank, a water outlet pipe is arranged in the air floatation tank, the water outlet of the water outlet pipe is located in the overflow weir, and an air floatation water outlet is formed in the overflow weir; the lower side of the pipe wall of the water outlet pipe in the overflow weir is also provided with an adjusting water outlet, and an adjusting valve is arranged on the adjusting water outlet.
Furthermore, the regulating valve comprises a baffle hinged on the regulating water outlet, a regulating handle is connected to the baffle, and the top of the regulating handle exceeds the overflow weir.
Furthermore, water inlet through holes are uniformly distributed on the water outlet pipes in the air flotation tank.
Furthermore, the size of the opening of the water outlet is adjusted to be at least half of the pipe diameter of the water outlet pipe.
To sum up, the utility model discloses possess following advantage:
the utility model discloses an to the regulation of delivery port water yield, adjust the liquid level in the air supporting pond in real time, the effectual too much entering of preventing sewage removes the cinder notch, reduces the mud moisture content, can effectively improve work efficiency.

fig. 2 is a schematic view of another perspective structure of the present invention;
fig. 3 is a schematic diagram of a regulator valve setting.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
example 1:
the utility model provides an air supporting pond mud regulation and control structure, includes air supporting pond 1, and what the back-and-forth movement was gone up in air supporting pond 1 is equipped with except that slag plate 2, removes slag plate 2 and scrapes mud into slag notch 3 on the air supporting pond 1, on removing the setting of slag plate, adopts the dolly to drive and removes slag plate reciprocating motion on the air supporting pond to realize scraping of air supporting pond top dross.
On the outflow of clear water, still be equipped with overflow weir 4 on the pool wall in air supporting pond 1, outlet pipe 5 sets up in air supporting pond 1, and outlet pipe 5's delivery port 51 is located overflow weir 4, and is concrete, and the equipartition has into water through-hole 53 on the pipe wall of outlet pipe in the air supporting pond, and the clear water gets into the outlet pipe from getting into the water through-hole to flow out from outlet port 51 and get into overflow weir.
An air floatation water outlet 41 is arranged on the overflow weir 4, and the clear water flowing out of the water outlet 51 and entering the overflow weir is discharged from the air floatation water outlet 41.
The pipe wall downside of outlet pipe 5 in overflow weir 4 still is equipped with adjusts delivery port 52, adjust delivery port 52 opening size and be half of the outlet pipe 5 pipe diameter at least, select for use in this embodiment for half of the outlet pipe diameter, be equipped with adjusting valve 6 on adjusting delivery port 52, it is concrete, refer to figure 3, adjusting valve 6 is including articulating baffle 61 on adjusting delivery port 52, be connected with adjustment handle 62 on baffle 61, adjustment handle 62 top surpasss overflow weir 4 to can make things convenient for operating personnel to adjust adjusting valve 6's opening size.
Specifically, the mechanism is further explained by combining the sewage pressurization and air floatation in the air floatation tank, sewage passes through the air inflation section in the air floatation tank in the rising process, flocs and suspended matters are fully mixed and contacted with micro bubbles, and because density difference exists between a gas-solid mixture and liquid, so that a vertical upward buoyancy is generated, the solid suspended matters are brought to the water surface, and then the slag removing plate 2 is used for scraping slag, so that the solid suspended matters enter the slag discharging tank 3.
And the clear water gets into the overflow weir from the outlet pipe, and at the air supporting in-process, the liquid level is too high, then can open the size through governing valve, increases its flow, and the control liquid level reduces, reduces out mud moisture content, and when the liquid level was crossed lowly and is not gone out mud, then can reduce its flow through governing valve, can reduce the valve opening or close the valve, improves liquid level.
And, in the adjustment process, adjust through adjustment handle 62, convenient, swift, of course, adjustment handle when adjusting to suitable angle, can be spacing on the air supporting pond, including but not limited to the bumping post is spacing, the draw-in groove is spacing, the area body is spacing.
It should be noted that at least one of the adjusting valves 6 is disposed on the water outlet pipe, and may be disposed on one side or both sides.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
Those skilled in the art will readily appreciate that the above-described preferred embodiments may be freely combined, superimposed, without conflict.
It will be understood that the above-described embodiments are illustrative only and not restrictive, and that various obvious and equivalent modifications and substitutions may be made in the details described herein by those skilled in the art without departing from the basic principles of the invention.
