[0002] Inclined tube (plate) sedimentation tank is a sedimentation tank with inclined tubes (plates) in the sedimentation area, mainly used for sewage treatment. Its working principle is to use the inclined tube (plate) as a sedimentation layer, through the water flow and particle sedimentation in the inclined tube, the suspended matter in the sewage is precipitated in the inclined tube and discharged from the mud discharge channel at the bottom of the tank, so as to achieve the purpose of purifying water quality.

[0003] The inclined tube sedimentation tank has the advantages of high sedimentation efficiency, small footprint, and good treatment effect, so it has been widely used in various industrial wastewater treatment. At the same time, the design and operation of the inclined tube sedimentation tank are relatively simple, easy to realize automatic management, and reduce operating costs. In addition, the inclined tube sedimentation tank can also be combined with other water treatment processes, such as grilles, regulating tanks, aeration tanks, etc., to form a complete water treatment system to improve the purification effect of water quality.

[0004] However, the inclined tube sedimentation tank also has its own structural limitations. During operation, there is often a problem of sludge accumulation and blockage, which affects the sewage treatment effect. The common method of dealing with sludge accumulation and blockage is to regularly drain all the water in the inclined tube sedimentation tank, and then flush water from the top of the tank to the bottom to clean the inclined tube and the sludge in the tank. This cleaning method is time-consuming and labor-intensive, inefficient, and affects the normal operation of the inclined tube sedimentation tank. Utility Model Content

[0006] The technical solution adopted by the utility model to solve the above technical problems is: an automatic cleaning device for an inclined tube sedimentation tank, comprising a driving mechanism, a truss and a flushing mechanism, the truss is arranged below the inclined tube in the inclined tube sedimentation tank, a slide groove is horizontally arranged in the inclined tube sedimentation tank, a pulley is installed on the truss, and the pulley can be slidably embedded in the slide groove, the flushing mechanism comprises a main pipe and a plurality of branch pipes, the main pipe and the plurality of branch pipes are horizontally fixed on the truss respectively, the main pipe is communicated with an external air supply mechanism, the plurality of branch pipes are respectively communicated with the main pipe, and a plurality of air holes are evenly opened at the bottom of each of the branch pipes, a reciprocating rod is connected to the output end of the driving mechanism, the reciprocating rod is connected to the truss via a connecting plate, and the driving mechanism is used to drive the truss to reciprocate along the slide groove through the reciprocating rod.

[0007] The utility model automatic cleaning device can perform air flushing from bottom to top when the inclined tube sedimentation tank is operating normally, and automatically clean the inclined tube sedimentation tank and the inclined tube. When in use, the driving mechanism drives the truss and the flushing mechanism to move back and forth along the slideway as a whole through the reciprocating rod, and at the same time, the external air supply mechanism supplies air to the main pipe. After the gas enters the plurality of branch pipes from the main pipe, it overflows from the air holes at the bottom of the plurality of branch pipes and enters the water body in the inclined tube sedimentation tank, thereby realizing air flushing of the inclined tube sedimentation tank and the inclined tube, and achieving the purpose of automatic cleaning without dead angles.

[0008] Preferably, the driving mechanism comprises a reduction motor, a crank, a first connecting rod, a first tripod, a second connecting rod and a second tripod. The reduction motor is mounted on the top of the outer wall of one side of the inclined tube sedimentation tank. The reduction motor, the crank, the first connecting rod, the first tripod, the second connecting rod and the reciprocating rod are hinged in sequence. The second tripod is fixed to the lower part of the outer wall of one side of the inclined tube sedimentation tank. The second tripod is hinged to the first tripod. The driving mechanism adopts the above design, which has a simple and reliable structure. When working, the power of the reduction motor is transmitted to the reciprocating rod via the crank, the first connecting rod, the first tripod and the second connecting rod in sequence, and the truss is driven to move back and forth along the slide groove by the reciprocating rod.

[0009] As a further preferred embodiment, a positioning sleeve is horizontally installed on one side wall of the inclined tube sedimentation tank, a sealing sleeve is embedded in the positioning sleeve, the outer end of the reciprocating rod passes through the sealing sleeve and is hinged to the second connecting rod, and the inner end of the reciprocating rod is hinged to the connecting plate.

[0010] Preferably, the main pipe is fixed at the middle of the truss, and the plurality of branch pipes are symmetrically arranged on both sides of the main pipe to achieve uniform and stable air flushing and cleaning effects.

[0011] Preferably, a plurality of pulleys are symmetrically installed on both sides of the moving direction of the truss, the number of the chutes is two, the two chutes are symmetrically set up in the inclined tube sedimentation tank, and a plurality of pulleys are arranged in each chute.

[0012] As a further preference, four positioning wheels are symmetrically installed on both sides of the moving direction of the truss, and two of the positioning wheels are slidably embedded in each of the chutes, and the wheel surface of each positioning wheel contacts the longitudinal surface of the chutes, and the wheel surface of each pulley contacts the bottom surface of the chutes. Since there is a lot of sediment in the inclined tube sedimentation tank, the truss may get stuck in the moving direction during the reciprocating movement along the chutes, and the four positioning wheels can prevent it from getting stuck. Since the directions of the four positioning wheels and several pulleys are different, when a pulley is stuck, the four positioning wheels can still move along the chutes, thereby ensuring the smoothness of the reciprocating movement of the truss and preventing the truss from swinging away from the moving direction.

When in use, the driving mechanism drives the truss and the flushing mechanism to move back and forth along the slideway as a whole through the reciprocating rod, and at the same time, the external air supply mechanism supplies air to the main pipe. After the gas enters the plurality of branch pipes from the main pipe, it overflows from the air holes at the bottom of the plurality of branch pipes and enters the water body in the inclined tube sedimentation tank, thereby realizing air flushing of the inclined tube sedimentation tank and the inclined tube, achieving the purpose of automatic cleaning without dead angles, solving the mud accumulation problem of the inclined tube sedimentation tank to the greatest extent, and ensuring the continuous and stable operation of the inclined tube sedimentation tank.
