Description

Technical Field

[0001] This utility model relates to the technical field of oxidation ponds for dyeing and printing wastewater treatment, specifically an oxidation pond for dyeing and printing wastewater treatment. Background Technology

[0002] The oxidation tank in dyeing and printing wastewater treatment is the core treatment unit used for the oxidative decomposition of pollutants in the dyeing and printing wastewater treatment process, belonging to the advanced wastewater treatment stage. Its main function is to decompose residual recalcitrant organic matter (such as dyes, sizing agents, surfactants), color, ammonia nitrogen, and some heavy metal ions in the wastewater into harmless or easily treatable substances by adding oxidants or utilizing microbial metabolic processes. This reduces the chemical oxygen demand (COD), biochemical oxygen demand (BOD), and color of the wastewater, enabling it to meet discharge standards or reuse requirements.

[0003] Currently, oxidation tanks used for treating dyeing and printing wastewater rely on aerators installed at the bottom of the tank to introduce air or oxygen into the water, providing dissolved oxygen (DO) for microbial metabolism or chemical oxidation reactions, thereby degrading pollutants in the wastewater. However, since the aerators are fixed to the bottom of the tank, disassembly, repair, or maintenance require manual entry into the tank. While replacing small structures is relatively convenient for material handling, replacing the entire pipeline is time-consuming, labor-intensive, and increases the workload and difficulty. Therefore, there is a need for an oxidation tank that can solve the above-mentioned drawbacks and improve its performance. Utility Model Content

[0004] The purpose of this utility model is to provide an oxidation tank for treating dyeing and printing wastewater, thereby solving the problems mentioned in the background section. To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] An oxidation treatment tank is provided with symmetrical connecting pipes on both sides of the lower part of the interior of the oxidation treatment tank, and aerators are provided at equal intervals above the outer surface of the connecting pipes.

[0007] The installation mechanism includes symmetrically arranged installation grooves on both sides below one end of the oxidation treatment tank, which fit and abut against the outer surface of one end of the connecting pipe. A guide frame is sleeved and connected below the outer edge of the installation groove and contacts the lower part of the outer surface of the connecting pipe. An installation head is fixedly connected to the other end of the connecting pipe and extends out of the oxidation treatment tank.

[0023] 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.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this utility model is an oxidation tank for treating dyeing and printing wastewater, comprising:

[0026] An oxidation treatment tank 11 has symmetrically arranged connecting pipes 12 on both sides of the lower part of the interior of the oxidation treatment tank 11, and aerators 13 are equidistantly connected above the outer surface of the connecting pipes 12.

[0027] A connecting pipe 14 is provided at the center position above the outer surface of the closely adjacent connecting pipe 12, and the connecting pipe 14 is designed in a horizontal "F" shape.

[0028] The connecting pipe 12 accommodates the structural installation of multiple aerators 13. Through the aerators 13 and the connecting pipe 14, an external air supply device can be used to supply dissolved oxygen (DO) to the water body by introducing air or oxygen, thereby achieving the degradation of pollutants in the wastewater.

[0029] The installation mechanism includes mounting grooves 21 symmetrically opened on both sides below one end of the oxidation treatment tank 11, which fit and abut against the outer surface of one end of the connecting pipe 12. A guide frame 22 is sleeved and connected below the outer edge of the mounting groove 21 and contacts the lower part of the outer surface of the connecting pipe 12. The other end of the connecting pipe 12 is fixedly connected to a mounting head 23, which extends out of the oxidation treatment tank 11. A threaded ring 24 is threadedly connected to the outer surface of the mounting head 23 and extends into the oxidation treatment tank 11.

[0030] The mounting groove 21 abuts against one end of the connecting pipe 12 to ensure the stability of the structure at that position. The threaded ring 24 limits the installation of the mounting head 23, thereby satisfying the fixation of the structure at the other end of the connecting pipe 12. With this installation method, when replacing or repairing the pipe later, the connecting pipe 12 can be directly moved out of the oxidation treatment tank 11 with the guide frame 22, which is time-saving, labor-saving, simple and convenient.

[0031] The outer surface of the threaded ring 24 is provided with rectangular protrusions at equal intervals, and anti-slip textures are distributed at equal intervals on the surface;

[0032] The rectangular protrusions combined with the anti-slip texture can increase contact friction and facilitate the control of the structure of the threaded ring 24.

[0033] It also includes a circulation mechanism, which includes circulation ports 31 symmetrically connected to the lower parts of both sides of the oxidation treatment tank 11. A circulation pipe 32 is attached to the inner wall of the circulation port 31, and a solenoid valve 33 is connected to the center position above the outer surface of the circulation pipe 32.

[0034] The connecting port, in conjunction with the flow pipe 32, allows for the free flow of wastewater, while the solenoid valve 33 controls the internal opening and closing of the flow pipe 32.

[0035] A positioning ring 34 is provided on the inner side of the outer surface of the flow pipe 32, which is attached to the oxidation treatment tank 11. Positioning bolts 35 are provided at equal intervals through the middle of the positioning ring 34 and are threaded into the oxidation treatment tank 11.

[0036] The positioning bolt 35 is used to install and fix the positioning ring 34, thereby satisfying the installation of the flow pipe 32 structure.

[0037] Working principle: The dyeing and printing wastewater to be oxidized enters the oxidation treatment tank 11 through a flow pipe 32. During this process, the solenoid valve 33 on the other flow pipe 32 is in the closed state. After the wastewater is transported, the solenoid valve 33 on the used flow pipe 32 needs to be closed. At this time, the connecting pipe 14 is connected to an external air supply device, which transports air or oxygen to the wastewater through the aerator 13 to provide dissolved oxygen (DO) required for microbial metabolism or chemical oxidation reaction, thereby achieving the degradation of pollutants in the wastewater. After long-term use, when it is necessary to inspect and maintain the aerator 13, connecting pipe 12 and other structures, small structures such as the aerator 13 can be directly lowered to the bottom of the tank for inspection and maintenance. For the large structure of the connecting pipe 12, the threaded ring 24 can be disassembled and, with the guidance of the guide frame 22, removed from the oxidation treatment tank 11 for subsequent inspection, maintenance or replacement.

[0038] This solution allows for the replacement of the large connecting pipe 12 by directly applying external pulling force at a low external location, along with the guide frame 22, to remove it from the oxidation treatment tank 11. This method is simple, convenient, time-saving, labor-saving, cost-effective, and helps improve the performance and replacement efficiency.

[0039] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment:

[0040] It also includes an auxiliary installation mechanism, which includes a thin-plate control switch 41 embedded in the innermost middle of the inner wall of the installation groove 21, a movable spring 43 fixedly connected to the outer edge of the innermost end of the installation groove 21, and alarm lights 45 symmetrically arranged on one side of the upper end of the oxidation treatment tank 11. A contact post 42 is provided in the middle of one side of the thin-plate control switch 41 and is in contact with one end of the connecting pipe 12.

[0041] The movable spring 43 contacts one end of the connecting pipe 12 and can deform and compress under continuous force application, and then contact the contact post 42, and transmit the force to the thin-plate control switch 41, which can trigger the alarm light 45 to flash for installation reminder, that is, the surface is installed in place. The signal of the thin-plate control switch 41 is SKRRABE010.

[0042] A hollow tube 44 is fixedly connected to the middle of the bottom end of the alarm light 45 and extends into the mounting groove 21. The alarm light 45 is electrically connected to the thin-film control switch 41 through a wire.

[0043] Hollow tube 44 is installed with alarm lights 45 and the wiring is required.

[0044] Working principle: During the installation of the connecting pipe 12, one end of the connecting pipe 12 extends into the mounting groove 21 and comes into contact with the movable spring 43. Under the continuous application of force, the movable spring 43 is compressed and deformed, causing one end of the connecting pipe 12 to extend into the mounting groove 21 until it comes into contact with the contact post 42, and then acts on the thin sheet pressure sensor, thereby triggering the alarm light 45 to flash, that is, the surface is installed in place.

[0045] This solution can assist in the installation of the connecting pipe 12, avoid the application of continuous installation force, further save time and effort, and improve the usage effect.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
