Description

Technical Field

[0001] This utility model relates to the field of dosing equipment technology, and in particular to a dosing device for denitrification in a denitrification biological treatment tank. Background Technology

[0002] In the field of wastewater treatment, denitrification biological tanks are a crucial step in nitrogen removal. Through the action of specific microorganisms, they convert nitrogen in the water into nitrogen gas, which is then released into the atmosphere, effectively reducing the nitrogen content in the water and preventing environmental problems such as eutrophication. During the denitrification process in denitrification biological tanks, various chemicals need to be precisely added to the tank to promote the growth and metabolism of microorganisms and improve denitrification efficiency. Currently, existing chemical dosing devices for denitrification in denitrification biological tanks have many limitations in structure and function, making it difficult to meet the diverse needs of actual production.

[0003] On the one hand, many dosing devices have a fixed dosing angle. However, in actual denitrification biological treatment tanks, the shape, size, and internal water flow distribution vary greatly. For example, in some large and irregularly shaped biological treatment tanks, the water flow velocity and direction differ in different areas, and the activity of microorganisms also varies. Dosing devices with fixed angles cannot be flexibly adjusted according to these actual conditions, resulting in the inability to evenly and accurately deliver the chemicals to the target area. Some areas may suffer from insufficient chemical dosing, affecting the denitrification effect, while other areas may suffer from excessive chemical dosing, leading to waste or even inhibiting microbial activity, thus affecting the overall nitrogen removal performance of the biological treatment tank.

[0004] On the other hand, some dosing devices are cumbersome to operate in terms of dosing tank installation and angle adjustment. The dosing tanks of some devices are not installed stably enough, and are prone to shaking or even falling off during operation. This not only affects the accuracy of dosing but may also damage other components of the device, increasing maintenance costs. Moreover, when the angle of the dosing tank needs to be adjusted, a complex disassembly and reinstallation process is often required, consuming a lot of time and manpower. Furthermore, during angle adjustment, the lack of an effective anti-rotation structure makes it easy for the limiting components to misalign, leading to inaccurate angle fixing, further affecting the dosing effect and the reliability of the device. Therefore, we provide a dosing device for denitrification biological treatment ponds. Utility Model Content

[0005] To address the aforementioned problems, this invention proposes a dosing device for denitrification in a denitrification biological treatment tank, which more accurately solves the problems mentioned in the background art.

[0006] This utility model is achieved through the following technical solution:

[0007] The utility model proposes a dosing device for denitrification in a denitrification biological treatment tank, including a column and a dosing tank. A control valve is fixedly installed at the discharge end of the dosing tank to control the discharge amount of the dosing tank.

[0008] A connecting column is fixedly welded to the upper end of the column, a first sleeve ring is sleeved around the connecting column, a second sleeve ring is fixedly welded around the first sleeve ring, a limiting iron ring is fixedly welded around the dosing tank, a strong magnetic ring is embedded on the upper surface of the second sleeve ring, a limiting end block is installed at the upper end of the connecting column, and a limiting mechanism is connected between the column, the first sleeve ring, and the limiting end block to realize the horizontal angle adjustment of the dosing tank.

[0009] Furthermore, the limiting mechanism includes a hole opened at the center of the column and the connecting column and a plug rod fixedly welded to the lower surface of the limiting end block. A spring is fixedly installed on the inner bottom wall of the hole. A limiting insertion hole is opened on the upper surface of the first sleeve ring, and a limiting insertion rod is fixedly installed on the lower surface of the limiting end block.

[0010] Furthermore, an anti-rotation structure is provided between the hole and the plug rod;

[0011] The anti-rotation structure includes an arc-shaped groove vertically formed around the plug rod and an arc-shaped strip vertically fixed to the inner wall of the hole, with the arc-shaped strip inserted into the inner wall of the arc-shaped groove.

[0012] Furthermore, the dosing can is inserted into the inner wall of the second sleeve ring, and the lower end surface of the inserted limiting iron ring is in contact with the upper end surface of the second sleeve ring.

[0013] Furthermore, the plug rod is inserted into the inner wall of the hole, and its lower end is fixedly welded to the upper end of the spring.

[0014] Furthermore, the lower end of the limiting rod is inserted into the inner wall of the limiting hole, and the inner diameter of the limiting hole is compatible with the outer diameter of the limiting rod.

[0015] The beneficial effects of this utility model are:

[0016] This utility model achieves flexible adjustment of the angle of the dosing tank in the horizontal plane by setting a limiting mechanism between the column, the first sleeve ring, and the limiting end block, and cooperating with the sleeve ring first and the connecting column. This allows the operator to simply lift the limiting end block upwards to disengage the limiting rod from the limiting insertion hole, and then freely rotate the first sleeve ring to adjust the dosing tank to the required angle. After adjustment, the limiting end block is released, and the limiting rod is reinserted into the limiting insertion hole under the action of the spring to complete the fixation.

[0017] This invention achieves initial fixation through the cooperation of a limiting iron ring and a strong magnetic ring embedded in the second sleeve ring, while the limiting mechanism provides precise positioning, ensuring the stability of the dosing canister installation. The magnetic ring's attraction to the limiting iron ring prevents the dosing canister from shaking or falling off within the second sleeve ring, providing a fundamental guarantee for the stability of the dosing process. The design of the limiting mechanism further enhances the convenience and reliability of operation. Attached Figure Description

[0023] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model. Example

[0024] like Figures 1-4As shown in the figure, an embodiment of this utility model discloses a dosing device for denitrification in a denitrification biological treatment tank, comprising a column 1 and a dosing tank 2. A control valve 3 is fixedly installed at the discharge end of the dosing tank 2 by welding or threaded connection. This control valve 3 has the function of precisely adjusting the opening degree, and can accurately control the discharge amount of the dosing tank 2 according to actual needs. For example, the dosing speed and total amount of the reagent can be flexibly adjusted according to the denitrification requirements of the denitrification biological treatment tank. A connecting column 4 is fixedly connected to the upper end of the column 1 by welding to ensure a firm connection. A first sleeve ring 5 is sleeved on the outer periphery of the connecting column 4, and the first sleeve ring 5 can rotate freely on the connecting column 4. A second sleeve ring 6 is fixedly installed on the outer periphery of the first sleeve ring 5 by welding, making the two a single structure. A limiting iron ring 7 is also fixedly installed on the outer periphery of the dosing tank 2 by welding. The limiting iron ring 7 is used to cooperate with the second sleeve ring 6 to support and limit the dosing tank 2. A strong magnetic ring 8 is embedded on the upper surface of the second sleeve ring 6. The strong magnetic ring 8 has a strong magnetic force and can attract the limiting iron ring 7, thereby fixing the position of the dosing tank 2 to a certain extent. A limiting end block 11 is installed on the upper end of the connecting column 4 by means of threaded connection or welding. The limiting end block 11 is used to prevent the first sleeve ring 5 from sliding out of the upper end of the connecting column 4. A limiting mechanism is connected between the column 1, the first sleeve ring 5 and the limiting end block 11. Through this limiting mechanism, the operator can manually rotate the first sleeve ring 5, thereby driving the dosing tank 2 to adjust its angle in the horizontal plane to meet the dosing needs of the denitrification biological treatment tank area in different locations.

[0025] Furthermore, a hole 9 is drilled at the center of the column 1 and the connecting column 4, penetrating both the column 1 and the connecting column 4. A plug-in rod 10 is fixedly installed on the lower surface of the limiting end block 11 by welding. The diameter of the plug-in rod 10 is slightly smaller than the diameter of the hole 9 to ensure smooth insertion. A spring 13 is fixedly installed on the inner bottom wall of the hole 9 by welding or bolting. The spring 13 has a certain length in its natural state. A limiting insertion hole 14 is drilled on the upper surface of the sleeve ring 5. The position and number of the limiting insertion holes 14 can be designed according to actual needs. A limiting plug rod 15 is fixedly installed on the lower surface of the limiting end block 11 by welding. The position of the limiting plug rod 15 corresponds to the limiting insertion hole 14. After the limiting end block 11 is installed in place, the plug-in rod 10 is inserted into the hole 9, and the limiting plug rod 15 is inserted into the limiting insertion hole 14, thereby achieving the limiting and fixing of the sleeve ring 5. When it is necessary to adjust the angle of the dosing tank 2, lift the limiting end block 11 upwards so that the limiting rod 15 disengages from the limiting insertion hole 14. At this time, the sleeve ring 5 can be rotated to adjust the angle of the dosing tank 2. After the adjustment is in place, release the limiting end block 11. Under the action of the spring 13, the limiting end block 11 moves downwards, and the limiting rod 15 is inserted into the corresponding limiting insertion hole 14 again to complete the angle fixation.

[0026] Furthermore, an arc-shaped groove 16 is vertically formed on the periphery of the insertion rod 10 using milling or other machining processes. The depth and width of the arc-shaped groove 16 are determined according to actual needs. An arc-shaped strip 17 is vertically fixed to the inner wall of the hole 9 by welding or integral molding. The shape and size of the arc-shaped strip 17 are adapted to the arc-shaped groove 16. When the insertion rod 10 is inserted into the hole 9, the arc-shaped strip 17 accurately engages with the inner wall of the arc-shaped groove 16, thereby restricting the rotation of the insertion rod 10 within the hole 9. This ensures that the limiting end block 11 does not rotate unnecessarily when adjusting the angle of the dosing tank 2, guaranteeing that the limiting insertion rod 15 can be accurately inserted into the limiting insertion hole 14.

[0027] Further, insert the dosing canister 2 into the inner wall of the second sleeve ring 6. During insertion, ensure that the limiting iron ring 7 on the dosing canister 2 corresponds to the position of the second sleeve ring 6. After the dosing canister 2 is fully inserted, the lower surface of the limiting iron ring 7 is tightly fitted with the upper surface of the second sleeve ring 6. At this time, the strong magnetic ring 8 at the upper end of the second sleeve ring 6 attracts the limiting iron ring 7, initially fixing the dosing canister 2 inside the second sleeve ring 6, preventing the dosing canister 2 from shaking or falling off at will, while not affecting the angle adjustment of the dosing canister 2 by rotating with the first sleeve ring 5 in the horizontal plane.

[0028] Furthermore, the connector 10 is inserted into the inner wall of the hole 9. During insertion, ensure that the connector 10 can smoothly enter the hole 9 and maintain a certain gap with the inner wall of the hole 9 so that it can move freely up and down. When the connector 10 is inserted to a certain depth, its lower end contacts the upper end of the spring 13, and the lower end of the connector 10 and the upper end of the spring 13 are fixedly welded together by welding. In this way, when the limiting end block 11 is lifted upward, the connector 10 will drive the spring 13 to compress; when the limiting end block 11 is released, the elastic force of the spring 13 will cause the connector 10 and the limiting end block 11 to move downward, thereby realizing the insertion and removal operation of the limiting connector 15.

[0029] Furthermore, after the limiting end block 11 is installed in place, the lower end of the limiting rod 15 is accurately inserted into the inner wall of the limiting hole 14. During the design and manufacturing process, the inner diameter of the limiting hole 14 and the outer diameter of the limiting rod 15 are strictly controlled to ensure that they are compatible. That is, the inner diameter of the limiting hole 14 is slightly larger than the outer diameter of the limiting rod 15, so as to ensure that the limiting rod 15 can be smoothly inserted into the limiting hole 14 and remain relatively stable after insertion without shaking or loosening, thereby achieving reliable limiting and fixing of the sleeve ring 5 and the dosing tank 2.
