Detailed Description
The inclined tube sedimentation tank of the sewage treatment plant provided by the invention will be described in detail with reference to the accompanying drawings and examples.
Example 1
As shown in fig. 1 and fig. 2, the inclined tube settling tank of the sewage treatment plant provided in this embodiment 1 includes a settling tank body, an inclined tube portion 3 disposed in the settling tank body and separating the settling tank body into a clean water region 1 and a settling region 2, the clean water region 1 being located above the settling region 2, and a mobile crane disposed above the clean water region 1, the mobile crane having a lower moving portion 42 extending into the settling region 2 and an upper moving portion 41 disposed above the lower moving portion 42 and located above the clean water region 1, the upper moving portion 41 and the lower moving portion 42 being movable together in a front-back direction with respect to the settling tank body,
the upper moving part 41 comprises a transverse moving mechanism and a vertical telescopic mechanism arranged on the moving part of the transverse moving mechanism, the telescopic end of the vertical telescopic mechanism can be stretched in a reciprocating manner along the up-down direction, and the telescopic end of the vertical telescopic mechanism is also fixedly connected with a nozzle 5 capable of spraying air to an inclined pipe below the vertical telescopic mechanism;
the lower moving part 42 is provided with an aeration pipe 6, and the aeration pipe 6 is positioned below the nozzle 5;
the movable travelling crane is further provided with an air source assembly, an air delivery end of the air source assembly is communicated with an air inlet end of the aeration pipe 6 through a first switch valve, and an air delivery end of the air source assembly is communicated with an air inlet end of the nozzle 5 through a second switch valve.
When the sedimentation tank body normally operates, the sewage liquid level 13 is as shown in fig. 1, when meeting the condition that the sedimentation tank body needs to be cleaned, the implementer can open the mobile crane, and move the vertical telescopic mechanism to the pipe chute top that needs to be cleaned, so that the telescopic end of the vertical telescopic mechanism stretches out, and the nozzle 5 fixedly connected to the telescopic end faces the pipe chute top below the vertical telescopic mechanism. After that, the practitioner alternately opens the first and second on-off valves, and the water enters the inclined tube under the pressure of the bubbles ejected from the aeration tube 6 and the nozzle 5 and flows back and forth in the inclined tube, thereby disturbing the impurities adhered to the inner wall of the inclined tube and separating them from the inner wall of the inclined tube. After the inclined pipes in the area are cleaned, the operator can adjust the transverse moving mechanism and the moving crane to move the nozzle 5 and the aeration pipe 6 to the next area for cleaning continuously.
More specifically, in the embodiment 1, the upper moving portion 41 includes the walkway 12, and the lateral moving mechanism is mainly composed of a horizontally disposed sliding shaft, and the vertical telescopic mechanism is slidably engaged with the sliding shaft so as to be slidable in the left-right direction. Due to the structural arrangement, compared with other transverse moving mechanisms such as a sliding groove and a sliding block, the transverse moving action of the vertical telescopic mechanism is more stable and reliable.
However, if a satisfactory cleaning effect is desired, it is necessary to adjust the position between the nozzle 5 and the inclined tube portion 3 a plurality of times so as to face the impurity concentrated region. And if the electric control driving structure is adopted to control the movement of the vertical telescopic mechanism along the left and right directions, the implementation cost is high, and the electric control movement precision requirement is high and the implementation is inconvenient because the vertical telescopic mechanism is required to move for a plurality of times in short distance along the left and right directions.

Wherein, implementation personnel stand and hold handheld pole 9 on walking 12 to along removing logical groove removal handheld pole 9, can realize the removal of vertical telescopic machanism in the left and right sides orientation, be applicable to the condition that needs short distance multiple removal in the left and right sides orientation more.
In this embodiment 1, the hand-held lever 9 is a screw rod, and a brake disc 10 is screwed to a portion of the hand-held lever extending above the walkway 12, the brake disc 10 includes a friction portion 11 forming a bottom thereof, and the brake disc 10 can be moved downward by rotating relative to the hand-held lever 9 so that the friction portion 11 thereof is in contact with a top surface of the walkway 12.
Specifically, when the vertical telescopic mechanism is moved to a predetermined position and is ready to be extended or retracted, as shown in fig. 2, the operator rotates the brake disc 10 to move it downward relative to the hand-held lever 9 until the friction portion 11 at the bottom thereof comes into contact with the top surface of the walkway 12, thereby generating frictional resistance that restricts the movement of the hand-held lever 9 in the left-right direction. Obviously, although there are many friction type brake mechanisms in the prior art, most of them have the defect of complicated structure, and the brake mechanism provided in this embodiment 1 combines the existing mobile roof to perform friction braking, has the advantage of simple structure, and is particularly suitable for the locking operation of the vertical telescopic mechanism.
In this embodiment 1, the gas transmission device is specifically a gas storage cylinder 7, a gas transmission end of the gas transmission device is respectively communicated with the gas inlet ends of the aeration pipe 6 and the nozzle 5 through a three-way pipe, the first switch valve is connected in series between the aeration pipe 6 and the gas storage cylinder 7, the second switch valve is connected in series between the nozzle 5 and the gas storage cylinder 7, and meanwhile, a pressure pump 14 is connected in series between the nozzle 5 and the gas storage cylinder 7.
In addition, in the present embodiment 1, the nozzle 5 and the gas cylinder 7 communicate with each other through a flexible hose.
