Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
It should be explained first that the location cleaning is not to clean the sludge out of the pool, but to clean and transfer the sludge at the planned position to make the installation position for the equipment pipeline.
Referring to fig. 1 and 2, the cleaning tool for positioning and cleaning sludge at the bottom of a sewage tank disclosed by the invention comprises an axle 11, a hub group, an air source steel pipe 12, an air distributing pipe 13 and the like.
The air source steel pipe 12 uses a zinc-coated pipe DN25, the length of the zinc-coated pipe is determined according to the size of the sewage pool, and one end of the zinc-coated pipe is ensured to be always above the water surface. For convenience of description, the left end of the air supply steel pipe 12 is referred to as a holding end, and the right end is referred to as a working end. The axle 11 is welded at the working end of the air source steel pipe 12, meanwhile, two reinforcing ribs 4 are symmetrically welded on the axle 11 for reinforcing, and the other ends of the reinforcing ribs 4 are welded on the air source steel pipe 12. The gas source steel pipe 12 is also symmetrically welded with two gas distributing pipes 13, and the joint of the two gas distributing pipes is opened. When the sludge treatment device works, air sprayed by the air source steel pipe 12 is responsible for blowing up sludge at the bottom of the tank, and air sprayed by the air distribution pipe 13 is responsible for blowing the sludge to two sides.
The hub group is composed of three parts, namely a rotating ring 51, supporting spokes 52 and a hub 53. Wherein the swivel 51 is fitted over the axle 11, the hub 53 is concentric with the swivel 51, and the support spokes 52 serve as a connection between the hub 53 and the swivel 51.
The middle part of the gas source steel pipe 12 is welded with a pull ring 2, and a traction rope 3 is tied on the pull ring 2
The steel rake 9 is hinged on the axle 11.
Referring to fig. 3, the air source steel pipe 12 is further hinged with an auxiliary positioning rod 6, a floating ball 7 is sleeved on the auxiliary positioning rod 6, and a baffle ring 8 is welded at the other end of the auxiliary positioning rod 6 and can intercept the floating ball 7 to prevent the floating ball from falling off from the auxiliary positioning rod 6. The floating ball 7 is red or yellow in appearance for easier identification
The implementation principle of the embodiment is as follows:
the preparation is first carried out by rubber tubing the compressed air source to the side of the lagoon and then the rubber tubing to the steel air source tube 12. Start compressed air source and the work end and the gas distribution pipe 13 of inspection air source steel pipe 12, can normally close compressed air source after the jet-propelled, sink the axletree 11, wheel hub group and the work end of air source steel pipe 12 in the sewage pond, tie up the pull ring 2 with haulage rope 3 at last.
The staff divide into two sets of, stands respectively in the both sides of effluent water sump, and a set of be responsible for promoting air supply steel pipe 12, and a set of be responsible for pulling haulage rope 3. The compressed air source is started to start the positioning and cleaning work, and two groups of workers simultaneously exert force to drive the part of the invention positioned in water to do linear reciprocating motion in the sewage pool.
During the movement, the compressed air is continuously sprayed out from the working end of the air source steel pipe 12 and the air distribution pipe 13. The air sprayed from the working end of the air source steel pipe 12 blows up the sludge on the bottom surface of the sewage pool, and the air sprayed from the air distribution pipe 13 blows the sludge to both sides.
In the process, two groups of workers need to observe the floating balls 7 on the water surface constantly, and the distances between the observation periods and the reference objects constantly are adjusted in time when deviation occurs, so that deviation of an actual cleaning area is avoided.
The staff at the holding end of the air source steel pipe 12 also needs to know the bottom surface condition of the sewage pool through vibration, which indicates that the sludge is deposited more frequently. Because wheel hub 53 is the steel wheel hub and does not install the rubber tire, belongs to rigid contact with bottom of the pool cement, can pass through vibrations with the bottom of the pool condition and transmit the staff.
The reciprocating cleaning is carried out for about three times, the sludge quantity can be obviously reduced, the steel rake 9 can be contacted with the residual hard sludge, the vibration at the moment is intermittent, the vibration area needs to be cleaned repeatedly, and when no obvious vibration exists in the whole cleaning area, the pool bottom is basically cleaned.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
