Description

Technical Field

[0001] The utility model relates to the field of sewage treatment aeration tanks, in particular to an anti-clogging sewage treatment aeration tank. Background Art

[0002] Aeration tanks are biochemical reactors designed according to the characteristics of microorganisms. The degree of degradation of organic pollutants mainly depends on the aeration reaction conditions designed by people. Aeration tanks use the activated sludge method to treat sewage. A certain sewage retention time is provided in the tank to meet the oxygen required by aerobic microorganisms and the mixing conditions for full contact between sewage and activated sludge. The aeration tank is mainly composed of three parts: the tank body, the aeration system and the inlet and outlet. The tank body is generally built of reinforced concrete, and the plane shape includes rectangular, square and circular.

[0003] Existing sewage treatment aeration tanks can pass air into the tank, which can provide oxygen for the microorganisms in the sewage to carry out degradation reactions, thereby accelerating the treatment of sewage. However, during the sewage treatment process, the air released by the aerator will float up quickly, and the air flow rate above is faster. The discharged gas fails to aerate the bottom of the aerator well, causing the air flow rate below the aerator to be slower, resulting in sludge and impurities accumulating at the bottom of the tank, reducing the convenience of using the aeration tank. Therefore, it is urgently necessary to design a sewage treatment aeration tank that can accelerate the air flow rate below. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a sewage treatment aeration tank that is anti-clogging, so as to solve the technical problem of the sewage treatment aeration tank that accelerates the air flow rate below.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blockage-resistant sewage treatment aeration tank, comprising a water tank, a cavity is opened inside the water tank, a first support tube and a second support tube are arranged at the inner bottom of the cavity, a shunt tube is arranged at one end of the second support tube, an air intake pipe is arranged on the outside of the shunt tube, a valve is arranged on the outer surface of the air intake pipe, a high-pressure nozzle is arranged on the surface of the second support tube, and the second support tube is rotatably connected to the shunt tube through a bearing.

[0006] By adopting the above technical solution, the second support tube allows the high-pressure nozzle to rotate to a suitable position through the bearing, and then opens the valve to allow the gas in the intake pipe to enter the diversion pipe, and then distributes it to multiple second support tubes in turn. Finally, the high-pressure nozzle sprays the gas on the bottom of the pool.

[0007] Furthermore, a support rod is disposed inside the cavity, and a data processor is disposed above the support rod.

[0008] By adopting the above technical solution, the data processor is set up to receive data from the sludge thickness detector to determine the thickness of the sludge accumulated in the aeration tank, thereby improving the outside world's understanding of the sludge accumulation situation inside the aeration tank.

[0009] Furthermore, a sludge thickness detector is arranged at the bottom of the support rod, the model of the sludge thickness detector is AMT-NS100, and a mounting plate is arranged on the outer side of the support rod.

[0010] By adopting the above technical solution and setting the mounting plate, the sensor can be well fixed on one side of the cavity, so that the sludge accumulation at the bottom of the pool can be received at any time, thereby improving the convenience of using the aeration tank.

[0011] Furthermore, a plurality of aeration heads are connected to the surface of the first support tube, and the plurality of aeration heads are arranged linearly and equidistantly.

[0012] By adopting the above technical solution, the aeration heads are arranged equidistantly and linearly, so that the aeration can be evenly distributed, the degradation rate of the wastewater can be accelerated, the loss of the aeration heads can be reduced, and the service life of the aeration heads can be extended.

[0013] Furthermore, the high-pressure nozzles are provided in a plurality of groups, and the plurality of groups of high-pressure nozzles are arranged linearly and equidistantly.

[0014] By adopting the above technical solution, high-pressure nozzles arranged in equidistant linear patterns can be used to process relatively dispersed sludge, and the spraying angle and intensity can be adjusted as needed, thereby improving the environmental applicability of the aeration tank.

[0015] Furthermore, a water inlet is provided at a lower corner of the water pool, and the water inlet is connected to an external sewage source.

[0016] By adopting the above technical solution, external sewage can enter the aeration tank through the water inlet and then be decomposed in the aeration tank, thereby improving the sewage treatment effect.

[0017] Furthermore, the second support tubes are provided in multiple groups, and the bearings are used for the relative rotation of the second support tubes and the diverter tubes.

[0018] By adopting the above technical solution, the second support tube rotates through the bearing, so that the high-pressure nozzle rotates, and then the spray angle of the high-pressure nozzle is adjusted according to demand, thereby accelerating the flow rate of air at the bottom of the pool, reducing the accumulation of sludge and impurities at the bottom of the aeration tank, and improving the convenience of using the aeration tank.

[0019] Furthermore, a plurality of the first support tubes and the second support tubes are arranged in a staggered manner.

[0020] By adopting the above technical solution, when the second support tube rotates through the bearing, the first support tube will not affect the movement trajectory of the second support tube, thereby optimizing the structure of the aeration tank.

[0021] In summary, the utility model mainly has the following beneficial effects:

[0022] 1. The utility model uses a high-pressure nozzle, and the second support pipe rotates the high-pressure nozzle to a suitable position through a bearing, and then opens the valve to allow the gas in the air inlet pipe to enter the diversion pipe, and then distributes it to multiple second support pipes in sequence. Finally, the high-pressure nozzle sprays the gas on the bottom of the pool, accelerates the flow rate of the bottom air, reduces the accumulation of sludge at the bottom of the pool, and thus improves the convenience of using the aeration tank.

[0023] 2. The utility model provides a sludge thickness detector. After the sludge thickness detector detects the thickness of the mud layer, the data is transmitted to the data processor, so that people outside can understand the sludge accumulation in the aeration tank, thereby improving the working efficiency of the aeration tank.
