Description

Technical Field

[0001] The utility model relates to the field of aerators, in particular to a liftable microporous aerator. Background Art

[0002] Aerators are commonly used pipeline equipment in the field of sewage treatment. In sewage treatment, aerobic reactions are usually required to remove organic matter in sewage. Aerobic reactions are usually carried out in aerobic tanks. By filling the aerobic tank with gas (oxygen) and utilizing aerobic microorganisms in the sewage, the organic matter in the sewage can be digested and degraded.

[0003] At present, in order to adapt to the water depth of the aerobic pool, the existing structure has a special lifting aerator device, which is usually lifted and released by a traction rope wound or released by a winding wheel. However, in the existing structure, the aerator is only pulled by a single lifter (one lifter corresponds to one aerator), which leads to high equipment cost investment and the lifter is not easy to install.

[0004] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0005] In view of the above-mentioned defects, the purpose of the utility model is to provide a liftable microporous aerator, which can lift and lower multiple groups of aerators by rotating the shaft, thereby reducing the investment cost of the equipment and at the same time reducing the complexity of equipment installation and facilitating installation.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a liftable microporous aerator, comprising a rotating shaft mounted on an aerobic tank and driven by a driver to rotate; the rotating shaft is connected to at least one group of aerators along its axial direction through a traction rope; the rotating shaft wraps the traction rope around its circumference to lift the aerator.

[0007] According to the liftable microporous aerator of the utility model, a positioning sleeve is fixedly sleeved on the rotating shaft; a baffle for positioning the wound traction rope is arranged at the end of the positioning sleeve; one end of the traction rope is fixedly connected to the peripheral surface of the positioning sleeve.

[0008] According to the liftable microporous aerator of the utility model, the connecting portion of the air pipe support is an annular structure, which is sleeved outside the rotating shaft and is clearance-fitted.

[0009] According to the liftable microporous aerator of the utility model, the connecting portion of the air pipe support is an annular structure, which is connected to the rotating shaft through a bearing.

[0010] According to the liftable microporous aerator of the utility model, the air pipe support is provided with a plurality of partially annular claws of different diameters.

[0011] According to the liftable microporous aerator of the utility model, a counterweight block is movably inserted on the air pipe support.

[0012] The utility model provides a liftable microporous aerator, including a rotating shaft mounted on an aerobic tank and driven by a driver to rotate; the two ends of the rotating shaft are supported by brackets, one end of the rotating shaft is connected to the output shaft of the driver, and the other end is rotatably mounted on the bracket. The rotating shaft is distributed along its axial direction by a traction rope to at least one group of aerators, and the aerator can be a disc-type microporous aerator (the aerator has a simple structure and low cost), and of course other aerator structures can also be selected. When the aerator is lifted, the driver drives the rotating shaft to rotate, and further wraps the traction rope around its circumference to lift the aerator; and when the aerator is lowered, the driver drives the rotating shaft to rotate in the opposite direction, and releases the traction rope to lower the aerator. Through the above structure, the rotating rotating shaft can lift and lower multiple groups of aerators. The utility model can lift and lower multiple groups of aerators through the rotating shaft, reducing the investment cost of the equipment, and at the same time, reducing the complexity of the equipment installation, which is convenient for installation.

[0018] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] See also Figure 1 and Figure 2The utility model provides a liftable microporous aerator, which includes a rotating shaft 1 mounted on an aerobic tank and driven by a driver to rotate; both ends of the rotating shaft 1 are supported by brackets, specifically, one end of the rotating shaft 1 is connected to the output shaft of the driver, and the other end is rotatably mounted on the bracket.

[0020] The rotating shaft 1 is connected to at least one group of aerators 2 by the traction rope 3 along its axial direction. The aerator 2 can be a disc-type microporous aerator (the aerator has a simple structure and low cost). Of course, other aerator structures can also be used. When the aerator 2 is lifted, the driver drives the rotating shaft 1 to rotate, and further wraps the traction rope 3 around its circumference to lift the aerator 2; and when the aerator 2 is lowered, the driver drives the rotating shaft 1 to rotate in the opposite direction, and releases the traction rope 3 to lower the aerator 2. Through the above structure, the rotating rotating shaft 1 can lift and lower multiple groups of aerators 2.

[0021] Preferably, in order to improve the positioning effect of the traction rope 3 during the winding process (to prevent the traction rope 3 from being excessively wound along the axial direction of the rotating shaft 1), a positioning sleeve 4 is fixedly sleeved on the rotating shaft 1 of the utility model. The fixed sleeve method can fix the rotating shaft 1 and the positioning sleeve 4 by a positioning bolt, so that the two can be rotated and positioned; a baffle 5 is provided at the end of the positioning sleeve 4 to position the wound traction rope 3, and the baffle 5 has a blocking effect on the traction rope 3 during the winding process. One end of the traction rope 3 is fixed to the circumference of the positioning sleeve 4. The rotating rotating shaft 1 winds the traction rope 3 onto the positioning sleeve 4.

[0022] See also Figure 3 and Figure 4 In addition, the rotating shaft 1 of the utility model is also equipped with an air pipe bracket 5 for supporting the air supply pipe of the aerator 2; the air pipe bracket 5 is rotationally connected to the rotating shaft 1; when the rotating shaft 1 is rotating, the air pipe bracket 5 always remains in a drooping state. When in use, the air supply pipe is installed on the air pipe bracket 5 (the specific installation method will be described in detail below), and the air pipe bracket 5 is always kept in a drooping positioning state to prevent the rotation effect of the rotating shaft 1 from acting on the air supply pipe, causing the air supply pipe to be entangled and affecting the normal operation of the equipment. The air pipe bracket 5 includes an annular connecting portion and a plurality of partially annular claws 7 of different diameters. During installation, the air supply pipe can be clamped into the corresponding claws 7 according to its diameter.

[0023] During the installation process, the annular connecting portion can be sleeved outside the rotating shaft 1 and have a clearance fit, or it can be connected to the rotating shaft 1 through a bearing.

[0024] Furthermore, a counterweight block 8 is movably inserted into the tracheal support 5 of the utility model, and a slot 51 for installing the counterweight block 8 is provided on the tracheal support 5.

[0025] In summary, the utility model provides a liftable microporous aerator, including a rotating shaft mounted on an aerobic tank and driven by a driver to rotate; the two ends of the rotating shaft are supported by brackets, one end of the rotating shaft is connected to the output shaft of the driver, and the other end is rotatably mounted on the bracket. The rotating shaft is distributed along its axial direction by a traction rope to at least one group of aerators, and the aerator can be a disc-type microporous aerator (the aerator has a simple structure and low cost), and of course other aerator structures can also be selected. When the aerator is lifted, the driver drives the rotating shaft to rotate, and further wraps the traction rope around its circumference to lift the aerator; and when the aerator is lowered, the driver drives the rotating shaft to rotate in the opposite direction, and releases the traction rope to lower the aerator. Through the above structure, the rotating rotating shaft can lift and lower multiple groups of aerators. The utility model can lift and lower multiple groups of aerators through the rotating shaft, reducing the investment cost of the equipment, and at the same time, reducing the complexity of the equipment installation, which is convenient for installation.
