Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment technical field, concretely relates to a kind of inclined tube sedimentation tank flushing mud scraping system. BACKGROUND

[0002] When inclined tube sedimentation tank is running, suspended particulate matter is deposited along the inclined tube wall, and water flow is collected by overflow tank after rising and then discharged. Inclined tube sedimentation process has an important problem in operation. Mud is easily attached to the inner wall of the inclined tube and its top. When water flows from bottom to top, suspended matter in water is deposited after hitting the inclined tube wall, and then water flow flows out of the inclined tube and enters the clear water zone. Suspended matter in the inclined tube has certain adhesion. After a period of operation, suspended matter may be attached to the inclined tube wall, which reduces the cross-sectional area of the inclined tube and increases the rising velocity of water flow, resulting in increased turbidity of the effluent. In addition, during the process of water flow entering the clear water zone, the flow rate decreases due to the increase in cross-sectional area, and part of the suspended matter in the water flow is thus deposited on the surface of the inclined tube. After a period of time, the inclined tube is blocked, thereby affecting the quality of the effluent.

[0003] The current conventional flushing method is to lower the water level in the tank and then use a high-pressure water gun to flush. This method has the following disadvantages: the water flow can break the generated flocs, causing the alum flowers to rise during the subsequent water inflow process, which affects the quality of the secondary effluent. Furthermore, this cleaning method requires a long shutdown time and consumes a lot of labor.

[0004] Therefore, the prior art has appeared a method of using a spray head to automatically spray and flush. However, the angle of the spray head cannot be adjusted, which to some extent causes flushing dead angles and affects the cleaning effect of the inclined tube. SUMMARY

[0005] In order to overcome the deficiencies in the prior art, the purpose of the present utility model is to provide a kind of inclined tube sedimentation tank flushing mud scraping system to improve the cleaning effect of the inclined tube.

[0006] The utility model solves the above problems by the following technical means:

[0007] A kind of inclined tube sedimentation tank flushing mud scraping system, including being arranged above inclined tube and being movable along the reciprocating movement of sedimentation tank trolley, lifting rod is arranged on the trolley, the bottom end of lifting rod is rotatably installed with rotating shaft, rotating shaft is horizontally arranged, rotating shaft is fixedly connected with spray pipe, multiple spray heads are arranged on the length direction of spray pipe at intervals, gear is fixedly connected on the spray pipe;The front and rear ends of the sedimentation tank in the moving direction of trolley are respectively fixedly provided with front end rack and rear end rack, the teeth of front end rack are arranged upwards, and the teeth of rear end rack are arranged downwards.

[0008] Further, the lifting rod is driven to lift by a lifting drive mechanism.

[0009] Further, a mud scraping plate is fixedly arranged on the travelling crane.

[0010] Further, the spray pipe is horizontally arranged.

[0011] Further, a plurality of the spray heads are uniformly spaced on the spray pipe.
