When the direction of the water flow is adjusted, firstly, a worker steps down on the driving portion 23, the driving portion 23 drives the first locking cylinder 21, the linkage portion 37, the second locking cylinder 36, the connecting portion 24, the first locking column 25 and the second locking column 38 to move downwards, meanwhile, the locking spring 22 is further compressed, until the bottom of the second locking cylinder 36 abuts against the tops of the two second support rods 33, at the moment, the top of the first locking column 25 is slightly lower than the bottom of the support ring 19, and the top of the second locking column 38 is slightly lower than the bottom of the extension cylinder 34, so that the worker is prevented from stepping on the driving portion 23 by the foot in transition, the locking spring 22 is protected, and at the same time, when the worker cannot continuously step down on the driving portion 23, the worker simultaneously indicates that at the moment, the first locking column 25 is separated from the first locking hole 26, and the second locking column 38 is separated from the second locking hole 35;
then, a worker rotates the driving handwheel 31 by two hands, the driving handwheel 31 drives the driving rod 28 and the driving worm 29 to rotate, the driving worm 29 drives the driving worm wheel 30 to rotate in the rotating process, and the driving worm wheel 30 drives the rotating rod 13 and the rotating plate 14 to rotate at the same time; if the sewage needs to be pumped into the anaerobic pool area, the rotating plate 14 is enabled to reach the first state, and the free end of the rotating plate 14 is abutted against the inner wall of the side, connected with the second return pipe 10, of the liquid outlet pipe 8; after the position is reached, the foot of the worker releases the driving part 23, then the first locking cylinder 21, the second locking cylinder 36, the linkage part 37, the first locking column 25, the second locking column 38 and the connecting part 24 all move upwards, meanwhile, the first locking column 25 is inserted into the first locking hole 26 corresponding to one position, the second locking column 38 is inserted into the second locking hole 35 corresponding to one position (wherein, according to the actual situation, the first locking hole 26 and the second locking hole 35 may not be uniformly distributed), and then the driving hand wheel 31 is released; in this state, when sewage flows into the rotating plate 14 through the liquid inlet pipe 6, although the sewage acts on the rotating plate 14, the side part of the rotating plate 14 is supported by the inner wall of the liquid outlet pipe 8, so that the position can be kept, and the sewage can only flow into the first return pipe 9;
moreover, when sewage flows through the end part of the free end of the rotating plate 14, the protection part 15 can play a role in blocking and guiding the sewage, so that the direct effect of the sewage on the rotating plate 14 can be better reduced, and the rotating plate 14 is protected; the first locking column 25 is inserted into the first locking hole 26, so that the support ring 19 cannot rotate, and the support ring 19 and the rotating plate 14 can be better supported by the first locking column 25, the lifting rod 20 and the like; meanwhile, the second locking column 38 passes through the second locking hole 35 on the extension cylinder 34, so that the extension cylinder 34 cannot rotate, and thus the driving worm 29, the driving worm wheel 30 and the rotating rod 13 cannot rotate, further ensuring the position stability of the rotating plate 14. Wherein the top of both the first and second locking levers are dome-shaped so as to facilitate access to the first and second locking holes 26, 35.
When sewage is required to be pumped into an anoxic zone, the supporting ring 19 and the extension cylinder 34 are unlocked in the same way, the driving hand wheel 31 is rotated to enable the free end of the rotating plate 14 to be attached to the inclined supporting part 16, and at the moment, the supporting part 16 can play a good supporting role and effect on the rotating plate 14, so that the sewage can normally act on the rotating plate 14 and then flow in the second return pipe 10.
Under some special conditions, for example, the power of the wall-through pump 5 is not enough, and the temperature is low or other factors cause poor effect of removing total nitrogen from the sewage, the rotating plate 14 is required to rotate to a state between the first state and the second state, and the sewage can flow into the anoxic tank and the anaerobic tank under the state, so that scientific reflux ratio can be achieved simultaneously, and the removal rate of the total nitrogen can be ensured.
At this time, the driving hand wheel 31 needs to be rotated, so that the rotating plate 14 stays at a position between the first state and the second state, then the driving part 23 is released, so that the first locking column 25 enters the first locking hole 26, the second locking column 38 enters the second locking hole 35, the support ring 19 is limited by the first locking column 25, and therefore cannot rotate, and the extension cylinder 34 is limited by the second locking column 38, so that the driving hand wheel 31 and the driving worm 29 cannot rotate, and therefore the rotating plate 14 can be kept stable at one position; since the first locking holes 26 and the second locking holes 35 are distributed one by one, when the angle of the rotating plate 14 is adjusted, several angles can be used, and not every angle can be stopped. At the same time, however, since the rotating plate 14 can stay at a plurality of different angles, the backflow ratio of the sewage can be simply adjusted, for example, more sewage can flow into the anoxic zone or the anaerobic zone, so that the sewage treatment device can be applied to various different situations, and the application range is wider.
In the using process, the supporting ring 19 has a larger diameter, so that a larger supporting arm can be provided when the rotating plate 14 is supported, and according to the lever principle, the acting force required by the supporting ring 19 to support the rotating plate 14 is smaller, the supporting stability is higher, meanwhile, the damage to the structure (namely, the first locking column 25 and the like) for supporting the position is smaller, and the using effect is better.
When the second locking cylinder 36 is used, the second locking cylinder 36 can be continuously sleeved on the lifting rod 20, at this time, the second locking column 38 needs to be arranged at the side part of the second locking cylinder 36, that is, the second locking column 38 can not influence the lifting rod 20 to pass through the second locking cylinder 36, and at this time, the supporting effect of the supporting rod on the second locking cylinder 36 can be ensured;
or as the state in the drawings, the second locking cylinder 36 is in a hood shape, and then the second locking column 38 is connected to the top of the second locking cylinder 36, so that the second locking cylinder 36 is prevented from deforming; then, when the second locking cylinder 38 and the extension cylinder 34 are unlocked, the second locking cylinder 36 can be sleeved on the top of the lifting rod 20, and then after the position adjustment of the rotating plate 14 is completed, the locking spring 22 raises the position of the second locking cylinder 36 through the first locking cylinder 21 and the linkage portion 37, so that the second locking cylinder 36 is separated from the top of the lifting rod 20, or the bottom of the second locking cylinder 36 is still sleeved on the lifting rod 20, but at this time, the two linkage portions 37 still maintain the state of being attached on the outer wall of the lifting rod 20, and the position of the second locking cylinder 36 can also be well maintained.
Wherein in the use, first bracing piece 32 and second bracing piece 33 can both further improve the positional stability of lifter 20 for the positional stability and the shape stability of lifter 20 can all be improved, have guaranteed the stability of using.
