Background
In the water treatment industry, high-density sedimentation tanks are generally used for treating various raw water and wastewater. In the high-density sedimentation tank, various medicaments are added to purify and soften the water quality so as to meet the requirements and conditions of a rear system on the water quality of the inlet water. In order to enhance the treatment effect, the high-density sedimentation tanks are provided with inclined pipes, and after a period of operation, a thin layer of sludge scale is formed in the inclined pipe sedimentation solid-liquid separation area, and the main components of the sludge scale are calcium-magnesium ion sediments generated by reaction, such as calcium carbonate, magnesium hydroxide and the like, and a mixture formed by various suspended matters, organic matters, colloid particles, microorganisms, coagulants and coagulant aids in incoming water. Once the sludge is accumulated in the inclined tube, the effect of precipitation separation of the sludge is gradually weakened, and meanwhile, the sludge in the precipitation separation area is further increased and thickened until the effect of the high-density sedimentation tank does not reach the treatment requirement and is forced to stop maintenance treatment. Too long treatment time is unfavorable for the good operation of the whole system, can lead to unbalanced water quantity of the whole system, and simultaneously, the treatment process consumes a large amount of working hours, manpower and material consumption. Therefore, the technology for efficiently solving the blockage of the pretreatment high-density pool is designed, and has great practical value for the operation of the whole water treatment process, the labor intensity and the consumption reduction.

Detailed Description
The objects, technical solutions and advantages of the present utility model will become more apparent by the following detailed description of the present utility model with reference to the accompanying drawings. It should be understood that the description is only illustrative and is not intended to limit the scope of the utility model. In addition, in the following description, descriptions of well-known structures and techniques are omitted so as not to unnecessarily obscure the present utility model.
In the prior art, the method for treating the inclined tube blockage mainly relies on manual cleaning at present, and the process is as follows:
(1) The series of plugs is isolated from the system and the high density settling pond water level is pumped below the down tube, which is related to the high density settling pond volume and drain pump size, typically requiring 10 hours and long drain times.
(2) The method has the advantages that the method is connected with a production water flushing system, and the fire-fighting lance head is used for large-area casting flushing, so that the water consumption is large, the flushing is not clean, and the effect on severely-blocked inclined pipes is not great; or a special hollow metal long pipe joint is adopted to wash one inclined pipe by one inclined pipe with pressurized water, and the method consumes a great deal of manpower and working hours.
(3) If the inclined tube is seriously blocked in a large area, the inclined tube needs to be dredged by long metal rods one by one, then the inclined tube is washed by production water, and the phenomenon of the inclined tube breakage frequently occurs, so that the treatment effect of the inclined tube of the high-density sedimentation tank is seriously reduced, and if the damage amount of the inclined tube reaches 10%, the inclined tube needs to be integrally replaced at the moment, so that a great amount of construction period is consumed, meanwhile, the use of spare parts is greatly increased, and the operation cost is increased uneconomically.
In order to solve the problems, as shown in fig. 1, a self-cleaning pretreatment high-density tank is provided, which consists of a water inlet pipe 1, a sedimentation tank 3, a sludge discharge pipe 9, an air inlet pipe 4, a sludge discharge pump 5 and a sludge storage pool 6; the sedimentation tank 3 is provided with a water inlet pipe 1, an inclined pipe 2 is arranged in the sedimentation tank 3, and a mud discharging pipe 9 is arranged at the bottom of the sedimentation tank 3; the sludge discharge pipe 9 is connected with the sludge discharge pump 5 through a sludge discharge pump inlet valve 8, an air inlet pipe 4 is arranged on the sludge discharge pipe 9, and an air valve 7 is arranged on the air inlet pipe 4; the outlet of the sludge pump 5 is connected with a sludge storage pool 6 through a pipeline.
Preferably, an air pressure gauge is arranged on the air inlet pipe.

A DN40 hole is formed on the sludge discharge pipe 9 of the sedimentation tank, the outside gauge pressure of 0.7Mpa factory air is introduced into the bottom of the sedimentation tank 3, an air valve 7 is added for control, and the addition amount of the factory air is controlled. After the sedimentation tank 3 stops running, factory air enters the bottom of the sedimentation tank 3 through a sedimentation tank sludge discharge pipe 9, a large number of bubbles which diffuse upwards to the tank surface can be formed due to pressure change, the bubbles are broken when passing through the inclined pipe 2, an air-floating boiling-shaped air-water mixture is formed, disturbing force is generated to peel off sludge and scale deposited on the inclined pipe 2, the sludge is deposited at the conical bottom of the sedimentation tank 3 after standing, and finally the sludge is discharged out of the system through a sludge discharge pump 5. The diaphragm pressure gauge is arranged behind the air valve 7 to control the air floatation quantity and the boiling effect, and the device has the characteristics of flexible adjustment means, stable control, strong practicability and the like, thereby ensuring the stable and controllable air floatation boiling of the pool surface of the sedimentation pool 3.
