Description

Technical Field

[0001] The utility model relates to a biochemical reaction aeration device, in particular to an adjustable biochemical reaction aeration device. Background Art

[0002] An aeration tank is a biochemical reactor designed according to the characteristics of microorganisms. The degradation degree of organic pollutants mainly depends on the designed aeration reaction conditions. The aeration tank uses the activated sludge method for sewage treatment, providing a certain sewage retention time in the tank to meet the oxygen demand of aerobic microorganisms and the mixing conditions for sufficient contact between sewage and activated sludge. The aeration tank mainly consists of a tank body, an aeration system, and an inlet and outlet. The tank body is generally made of reinforced concrete, and its planar shape can be rectangular, square, circular, etc.

[0003] Traditional aeration methods are all balanced full-tank complete mixing aeration. However, the COD itself is unevenly distributed in the biochemical reaction tank, especially in large biochemical reaction tanks. This not only causes waste of gas but also easily leads to sludge aging and reduced effluent quality due to excessive aeration. Content of the Utility Model

[0004] To solve the problems raised in the above background art, the utility model provides a biochemical reaction aeration device.

[0005] To achieve the above object, the utility model provides the following technical solution: A biochemical reaction aeration device includes a base. A lifting cylinder is fixedly connected to the upper surface of the base. A connecting sleeve a is installed in the bearing on the upper surface of the lifting cylinder. A screw rod is fixedly connected to the inner wall of the connecting sleeve a. A lifting component is arranged on the outer surface of the screw rod. A plurality of connecting plates b are symmetrically and fixedly connected to the outer surface of the connecting sleeve a. The front surface of the connecting plate b is fixedly connected to the front surface of the inner wall of the connecting sleeve b. A rotating component is arranged on the outer surface of the connecting sleeve b. A sliding sleeve is slidably connected to the outer surface of the lifting cylinder. A fixed sleeve is rotatably connected to the outer surface of the sliding sleeve. A communicating pipe is installed on the outer surface of the fixed sleeve.

[0006] Preferably, the lifting component includes a threaded sleeve threadedly connected to the outer surface of the screw rod. A plurality of connecting plates a are fixedly connected to the outer surface of the threaded sleeve. One end of the front surface of the connecting plate a passes through a limiting groove and is fixedly connected to the front surface of the inner wall of the sliding sleeve. The limiting groove is opened on the outer surface of the lifting cylinder.

[0007] Preferably, the top end of the screw rod is rotatably connected to the lower surface of the top plate.

[0008] Preferably, the rotating component includes a gear a installed on the outer surface of the connecting sleeve b. The outer surface of the gear a meshes with the outer surface of a gear b. The upper surface of the gear b is fixedly connected to the output shaft of a servo motor. The servo motor is installed on the lower surface of the top plate.

[0009] Preferably, the lower surface of the gear a is fixedly connected to the upper surface of the fixed sleeve through a plurality of spring rods.

[0010] Preferably, a plurality of shunt pipes are symmetrically installed on the outer surface of the communicating pipe, and a plurality of anti-blocking nozzles are symmetrically installed on the upper surface of the shunt pipe.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] In the present utility model, the servo motor a drives the gear b and the gear a to rotate. The rotation of the gear a drives the connecting plate b, the connecting sleeve a and the screw rod to rotate. The rotation of the gear a drives the spring rod and the fixed sleeve to rotate. The rotation of the fixed sleeve drives the communicating pipe, the shunt pipe and the anti-blocking nozzle to rotate, so as to uniformly aerate the inside of the biochemical reaction tank. The rotation of the screw rod drives the threaded sleeve and the connecting plate a to move upward. The upward movement of the connecting plate a drives the sliding sleeve, the fixed sleeve, the communicating pipe, the shunt pipe and the anti-blocking nozzle to move upward, so as to adjust the aeration depth of the biochemical reaction. This solves the problems that in the existing device, the COD is unevenly distributed in the biochemical reaction tank, resulting in waste of gas, and at the same time, excessive aeration is likely to cause sludge aging and reduce the effluent effect.
