Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an air intake regulating mechanism for an aeration pipeline. Background Technology

[0002] In wastewater treatment processes, aeration is a crucial step. By introducing air into the wastewater, aerobic microorganisms are provided with the necessary oxygen to decompose organic pollutants. The aeration pipeline system is the core equipment for achieving this process.

[0003] Existing aeration pipelines typically consist of a main horizontal pipe and several branch aeration pipes extending into the water. To regulate the aeration rate, a main valve is usually installed at the blower outlet or the main pipe inlet to control the total airflow. However, simply adjusting the total airflow can lead to inconsistent actual airflow in each branch aeration pipe, resulting in over-aeration in some areas of the aeration tank and under-aeration in others—a condition known as "uneven aeration." Uneven aeration severely affects the activity and distribution of microorganisms, reduces wastewater treatment efficiency, and can even cause problems such as sludge bulking.

[0004] Therefore, there is an urgent need for an air intake regulating mechanism that can ensure uniform and adjustable air volume at each aeration point. Utility Model Content

A control mechanism is provided on the transverse aeration pipeline, and an arc-shaped regulating plate is provided inside the transverse aeration pipeline. The control mechanism is used to control the movement of the arc-shaped regulating plate.

[0008] The arc-shaped regulating plate is closely attached to the inner wall of the transverse aeration pipe and can move horizontally inside the transverse aeration pipe; the arc-shaped regulating plate has a linear array of regulating slots that correspond one-to-one with the aeration branch pipes, and the opening size of the regulating slots decreases sequentially in the direction away from the moving circle.

[0009] Preferably, the control mechanism includes a threaded sleeve, a fixed block, a control screw, and a movable ring;

[0010] The threaded sleeve is fixed at the center of one end of the transverse aeration pipe, and the fixing block is fixed at the top of the inner wall of the transverse aeration pipe; one end of the control screw is threadedly connected to the threaded sleeve and extends to the outside of the transverse aeration pipe, and the other end is rotatably connected to the fixing block; the movable ring is threadedly connected to the control screw; one side of the movable ring is fixedly connected to the arc-shaped adjustment plate.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] An air intake adjustment mechanism for an aeration pipeline includes a transverse aeration pipeline 1. The bottom of the transverse aeration pipeline 1 is fixedly connected to a plurality of aeration branch pipelines 101 arranged in a linear array. The other end of the aeration branch pipelines 101 can extend into the water body to aerate the water body. The number and size of the aeration branch pipelines 101 and the size of the transverse aeration pipeline 1 can be designed and adjusted according to actual needs.

[0026] An aeration input pipe 102 is fixedly connected to the top of the transverse aeration pipe 1. The aeration input pipe 102 can be connected to an external aeration pump, which can pressurize air and input it into the interior of the transverse aeration pipe 1 through the aeration input pipe 102.

[0027] At least two sets of fixing sleeves 2 are welded and fixed on the outer surface of the transverse aeration pipe 1. One side of the fixing sleeve 2 is a rectangular part 201. A transverse fixing slot 202 is opened on the rectangular part 201. The rectangular part 201 is one end close to the side wall of the sewage aeration tank. The rectangular part 201 is fixed to the side wall of the sewage aeration tank by bolts passing through the transverse fixing slot 202 (the side wall of the sewage aeration tank has a metal support frame with screw holes).

[0028] A control mechanism is provided on the transverse aeration pipeline 1. The control mechanism includes a threaded sleeve 301 and a fixing block 302. The fixing block 302 is fixed to the top of the inner wall of the transverse aeration pipeline 1. The threaded sleeve 301 is fixed to the center of one end of the transverse aeration pipeline 1. A control screw 303 is threadedly connected to the threaded sleeve 301. A control turntable 304 is fixedly connected to one end of the control screw 303 located outside the transverse aeration pipeline 1. The control screw 303 can be rotated by manually rotating the control turntable 304.

[0029] One end of the control screw 303 located inside the transverse aeration pipe 1 is rotatably connected to the fixed block 302. The fixed block 302 assists in supporting the control screw 303. A movable ring 305 is threadedly connected to the control screw 303. By rotating the control screw 303, the movable ring 305 can be driven to move. A guide shaft 306 is fixedly connected between the fixed block 302 and the inner wall of the transverse aeration pipe 1. The guide shaft 306 and the movable ring 305 are slidably connected to ensure the horizontal movement of the movable ring 305. The movable ring 305 has a screw hole and a through hole to realize the threaded connection with the control screw 303 and the slidable connection with the guide shaft 306.

[0030] An arc-shaped adjusting plate 4 is fixedly connected to one side of the movable ring 305. The arc-shaped adjusting plate 4 is close to the inner wall of the transverse aeration pipe 1 and can move along the inner bottom of the transverse aeration pipe 1 under the action of the movable ring 305. The arc-shaped adjusting plate 4 has a linear array of regulating slots 401. The number of regulating slots 401 is the same as the number of aeration branch pipes 101 and they are set one-to-one. The opening size of the regulating slots 401 decreases in the direction away from the movable ring 305. When the aeration pipe is aerating, most of the air needs to pass through the regulating slots 401. A small amount of air enters the aeration branch pipe 101 along the arc-shaped adjusting plate 4 and the inner wall of the transverse aeration pipe 1, which will not affect the ventilation volume adjustment during aeration.

[0031] The working principle of the air inlet volume regulating mechanism for an aeration pipeline provided by this utility model is as follows:

[0032] When it is necessary to adjust the air intake of the aeration pipeline, manually rotate the control turntable 304 in different directions, which in turn drives the control screw 303 to rotate in different directions. When the control screw 303 rotates in different directions, the movable ring 305 can move horizontally in different directions, and the movable ring 305 drives the arc-shaped adjustment plate 4 to move in different directions.

[0033] When the arc-shaped regulating plate 4 moves towards the moving ring 305, the opening of the corresponding regulating slot 401 above the aeration branch pipe 101 gradually decreases, reducing the air intake volume entering the aeration branch pipe 101 through the regulating slot 401, and ultimately reducing the aeration volume.

[0034] When the arc-shaped regulating plate 4 moves away from the movable ring 305, the opening size of the corresponding regulating slot 401 above the aeration branch pipe 101 gradually increases, thereby increasing the air intake volume entering the aeration branch pipe 101 through the regulating slot 401 and ultimately increasing the aeration volume.

[0035] Compared with related technologies, the air inlet volume adjustment mechanism for an aeration pipeline provided by this utility model has the following beneficial effects:

[0036] This invention utilizes the horizontal movement of the arc-shaped adjustment plate 4 to adjust the opening size of the corresponding control slot 401 above the aeration branch pipe 101, ultimately achieving adjustment of the air intake at the opening end of each aeration branch pipe 101. While adjusting the air intake of the aeration pipe, it ensures the uniformity of aeration of sewage through multiple aeration branch pipes 101, avoiding uneven aeration that leads to insufficient aeration in some areas and affects the sewage treatment capacity.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
