Description

Technical Field

[0001] This utility model relates to the field of integrated wastewater treatment technology in chemical industrial parks, specifically a device for adding denitrifying bacteria to integrated wastewater in chemical industrial parks. Background Technology

[0002] Chemical wastewater refers to process wastewater, cooling water, and exhaust gas scrubbing water discharged during chemical production. It contains toxic substances such as cyanide, phenol, and heavy metals, and is characterized by complex composition, high COD concentration, high salt content, and high content of recalcitrant compounds. In some chemical industrial parks, anoxic tanks are used for wastewater treatment. Denitrifying bacteria are usually added to the anoxic tank to treat the wastewater. Currently, denitrifying bacteria dosing devices utilize the fusion of water and bacteria before adding them to the anoxic tank. However, the mixing effect of current denitrifying bacteria dosing devices is not good, and the water cannot be agitated, which is not conducive to the rapid and uniform mixing of bacteria and water. As a result, inaccurate dosing can easily occur during the dosing process, making it inconvenient to use.

[0003] Therefore, we propose a comprehensive denitrifying bacteria dosing device for wastewater in chemical industrial parks to improve and supplement existing technologies. Utility Model Content

Detailed Implementation

[0021] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 A device for adding denitrifying bacteria to integrated wastewater in a chemical industrial park includes a hollow addition tank 1. A drive motor 13 is installed on the top of the tank, and a discharge pipe 10 is fixedly connected to the bottom. A valve is installed on the discharge pipe 10 to open and close the discharge pipe 10. When the valve is opened, the liquid in the addition tank 1 can be discharged through the discharge pipe 10. The addition tank 1 is a cylindrical shell with a water injection pipe 9 fixedly connected to the upper part of its side. Water can be injected into the addition tank 1 through the water injection pipe 9. A connecting block 11 is fixedly welded to the side of the addition tank 1. A mounting plate 12 with four holes is fixedly connected to the side of the connecting block 11. The mounting plate 12 can be installed on a frame near an anoxic pool by bolts passing through it. A feeding cover 8 is provided on the top of the addition tank 1. The feeding cover 8 can be removed from the addition tank 1 by pinching the side and pulling it upwards. Then, denitrifying bacteria can be added into the addition tank 1 from the top.

[0023] The drive motor 13 is an electric drive device that provides rotational driving force. A central shaft 2 is fixedly connected to its output shaft. The bottom end of the central shaft 2 extends downwards and penetrates into the interior of the dosing tank 1. Four arc-shaped plates 3 are fixedly welded to the side of the central shaft 2, with each pair corresponding to the other. A fixing sleeve 5 connects the two corresponding arc-shaped plates 3. A stirring rod 4 is fixedly connected to the side of the central shaft 2. When the drive motor 13 operates, it drives the stirring rod 4 through the central shaft 2, causing the stirring rod 4 to stir the water and denitrifying bacteria in the dosing tank 1. A rotating cylinder 14 is rotatably connected inside the fixing sleeve 5. The rotating cylinder 14 is an intermediate... The rotating cylinder 14, with its narrow and wide cylindrical structure, can rotate within the fixed sleeve 5 without falling off. In actual manufacturing, the narrow middle part of the rotating cylinder 14 matches the fixed sleeve 5, while the wider edges on both sides contact the sides of the fixed sleeve 5. A driven gear 16 is fixedly connected to the side of the rotating cylinder 14, and a gear ring 15 is fixedly connected to the inner wall of the feeding box 1. The driven gear 16 and the gear ring 15 mesh with each other. When the drive motor 13 is working, the central shaft 2 will drive the fixed sleeve 5 to move through the arc plate 3. The meshing of the driven gear 16 and the gear ring 15 causes the rotating cylinder 14 to rotate.

[0024] A turning rod 6 is fixedly connected to the side of the rotating cylinder 14 away from the driven gear 16. Several turning plates 7 are fixedly welded to the side of the turning rod 6. When the rotating cylinder 14 rotates in the fixed sleeve 5, the turning rod 6 will also rotate, and the turning rod 6 will drive the turning plates 7 to move. The turning plates 7 will stir up the water and denitrifying bacteria, and accelerate the mixing efficiency of the water and denitrifying bacteria. In addition, several auxiliary rods 17 are fixedly welded to the side of the arc plate 3. When the arc plate 3 moves due to the drive of the central shaft 2, the auxiliary rods 17 also play a stirring role.

[0025] A feeding block 18 is fixedly connected to the bottom of the inner wall of the feeding box 1. The inner side of the feeding block 18 is an inclined sliding surface, which guides the solution to be discharged from the feeding box 1 through the discharge pipe 10. A gasket 19 is fixedly connected to the top of the gear ring 15. The inner side of the gasket 19 is also inclined, which can effectively prevent the solution from accumulating on the top of the gear ring 15.

[0026] Finally, the electric drive equipment needs to be equipped with a switch. This technical solution also has a switch. When the switch is turned on, the drive motor 13 will work. When the switch is turned off, the drive motor 13 will stop working. The switch is existing technology, so this technical solution does not elaborate too much on the switch.

[0027] In use, remove the feeding cover 8, fill the feeding tank 1 with denitrifying bacteria, inject water into the feeding tank 1 through the water injection pipe 9, and control the drive motor 13 to work through the switch. The drive motor 13 will drive the central shaft 2 to rotate, and the central shaft 2 will drive the stirring rod 4 to rotate. The stirring rod 4 will play a stirring purpose. The central shaft 2 will drive the arc plate 3 to move, and the arc plate 3 will drive the fixed sleeve 5 to move. Since the gear ring 15 and the driven gear 16 mesh, the rotating cylinder 14 will rotate. The turning rod 6 will drive the turning plate 7 to move. The turning plate 7 will turn the water and denitrifying bacteria up and down, accelerating the mixing process. Open the valve on the discharge pipe 10, and the material can be added to the anoxic tank through the discharge pipe 10.
