Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an auxiliary dosing device for wastewater treatment. Background Technology

[0002] Wastewater treatment refers to the process of purifying various types of sewage, such as domestic sewage, industrial wastewater, and rainwater, using physical, chemical, and biological methods to remove pollutants and ensure that the treated water meets the prescribed discharge standards or reuse requirements. Chemical dosing is an indispensable and crucial step in the wastewater treatment process. Its core purpose is to enhance the removal effect of pollutants and improve treatment efficiency by adding specific agents to the wastewater treatment pond.

[0003] Currently, existing wastewater treatment dosing devices have significant drawbacks: these devices typically inject chemicals directly into the wastewater treatment tank from the outside using pumps. Because the injection points are relatively concentrated, the chemicals often accumulate in one area of ​​the tank, failing to diffuse effectively throughout. This localized accumulation leads to a series of problems: for example, excessively high local concentrations may result in waste and even negatively impact the microbial environment within the tank, disrupting the stability of the biological treatment process; insufficient chemical concentrations in other areas of the tank prevent adequate contact and reaction with pollutants, thus affecting wastewater treatment efficiency and making it difficult to consistently meet effluent quality standards. Therefore, there is an urgent need to design an auxiliary dosing device for wastewater treatment to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary dosing device for wastewater treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wastewater treatment auxiliary dosing device, comprising:

[0007] A wastewater treatment tank, wherein an L-shaped support is provided on the wastewater treatment tank;

[0008] A movable mechanism, which is mounted on an L-shaped support;

[0009] A dosing tank is fixedly installed at the moving end of the moving mechanism, and the center of the dosing tank coincides with the center of the sewage treatment tank.

[0010] A stirring assembly is disposed between the top of the dosing tank and the L-shaped support;

[0011] The bottom of the dosing tank is equipped with a spraying mechanism, which includes spray pipes that are evenly distributed in a ring at the bottom of the dosing tank and the bottom of the L-shaped support. One end of each spray pipe is equipped with the same liquid extraction component as one side of the dosing tank. The bottom of each spray pipe is fixedly equipped with an evenly spaced, inclined nozzle.

[0013] Furthermore, the moving mechanism includes a movable groove and a mounting cavity formed on an L-shaped support, and a threaded rod is rotatably connected to the inner wall of the movable groove. One end of the threaded rod extends into the interior of the mounting cavity. A forward and reverse motor is fixedly installed on the top of the mounting cavity, and bevel gears are fixedly installed on the output shaft of the forward and reverse motor and one end of the threaded rod. The two bevel gears mesh with each other. A movable seat is screwed to the outer wall of the threaded rod, and the dosing tank is fixedly installed on one end of the movable seat.

[0014] Furthermore, slide rails are fixedly installed on both inner walls of the movable groove, and slide grooves are opened on both sides of the movable seat, with the outer wall of the slide rail matching the inner wall of the slide groove.

Detailed Implementation

[0028] 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.

[0029] Please see Figures 1-5 In this embodiment of the present invention, a wastewater treatment auxiliary dosing device includes:

[0030] Wastewater treatment tank 1, with an L-shaped support 4 on the wastewater treatment tank 1, and an installation support 2 fixedly installed on one side of the outer wall of the wastewater treatment tank 1, and an installation rod 3 fixedly installed on the top of the installation support 2 and the bottom end of the L-shaped support 4.

[0031] The moving mechanism 5 is mounted on the L-shaped support 4;

[0032] The dosing tank 6 is fixedly installed on the moving end of the moving mechanism 5, and the center of the dosing tank 6 coincides with the center of the sewage treatment tank 1. A dosing pipe 9 is fixed on one side of the top of the dosing tank 6, and a sealing cap 10 is screwed to the top of the dosing pipe 9.

[0033] Agitator 7 is disposed between the top of the dosing tank 6 and the L-shaped support 4;

[0034] A spraying mechanism 8 is provided at the bottom of the dosing tank 6. The spraying mechanism 8 includes spray pipes 81 that are evenly distributed in a ring at the bottom of the dosing tank 6 and the bottom of the L-shaped support 4. One end of each spray pipe 81 is connected to the same liquid extraction component on one side of the dosing tank 6. Each spray pipe 81 has an evenly spaced, inclined nozzle 82 fixedly installed at its bottom. The inclination angle of the nozzle 82 gradually increases from the inside to the outside of the wastewater treatment tank 1, and the bottom of the nozzle 82 is higher than the top of the wastewater treatment tank 1. The liquid extraction component includes a liquid extraction pump 86 fixedly installed in the middle of the bottom of the dosing tank 6, and the outlet end of the liquid extraction pump 86 is connected to one side of the spray pipe 81. The inlet end of the pump 86 is fixedly connected to the outlet pipe 85, and the bottom side of the dosing tank 6 is fixedly connected to the outlet pipe 83. A control valve 84 is fixedly installed at one end of the outlet pipe 83 and one end of the pump 85. Since the spray pipes 81 are evenly distributed in a ring, and the tilt angle of the nozzles 82 gradually increases from the inside to the outside of the sewage treatment tank 1, the agent can cover all areas of the sewage treatment tank 1 after being sprayed out by the nozzles 82. This effectively solves the problem of local accumulation and uneven diffusion of the agent in traditional devices, thereby ensuring that the agent and the sewage are fully in contact and react, and avoiding the situation of excessively high or insufficient local concentration.

[0035] Specifically, the moving mechanism 5 includes a movable groove 53 and a mounting cavity 56 formed on the L-shaped support 4. A threaded rod 54 is rotatably connected to the inner wall of the movable groove 53, with one end of the threaded rod 54 extending into the interior of the mounting cavity 56. A forward / reverse motor 51 is fixedly mounted on the top of the mounting cavity 56, and bevel gears 52 are fixedly mounted on both the output shaft of the forward / reverse motor 51 and one end of the threaded rod 54. The two bevel gears 52 mesh with each other. A movable seat 55 is screwed to the outer wall of the threaded rod 54, and a dosing tank 6 is fixedly mounted on one end of the movable seat 55. Both inner walls of the movable groove 53 are fixedly mounted with… The slide rail 57 and the movable seat 55 are provided with grooves 58 on both sides. The outer wall of the slide rail 57 is adapted to the inner wall of the groove 58. The forward and reverse motor 51, the liquid pump 86 and the control valve 84 are all connected to a switch through wires, and the switch is connected to a power source through wires. The forward and reverse motor 51 drives the bevel gear 52 to rotate. The meshing transmission of the two bevel gears 52 causes the threaded rod 54 to rotate in the movable groove 53. The movable seat 55 on the outer wall of the threaded rod 54 moves smoothly with the cooperation of the slide rail 57 and the groove 58, thereby driving the dosing box 6 to move, which facilitates the dosing and subsequent spraying operations.

[0036] Specifically, the stirring assembly 7 includes a stirring shaft 72 rotatably connected to the middle of the dosing tank 6, and stirring blades 74 are fixedly installed on the bottom of the outer wall of the stirring shaft 72. A gear 73 is fixedly installed on the top of the stirring shaft 72, and a rack frame 71 is fixedly installed on the top of the L-shaped support 4. The rack frame 71 meshes with the gear 73. When the dosing tank 6 moves, the gear 73 on the top of the stirring shaft 72 meshes with the rack frame 71, driving the stirring shaft 72 to rotate. The stirring blades 74 rotate accordingly to stir the agent in the dosing tank 6 to prevent sedimentation and stratification.

[0037] The working principle of this utility model is as follows: First, the agent is added into the dosing tank 6 through the dosing pipe 9 and the sealing cover 10 is closed; then, the forward and reverse motor 51 is started, which drives the bevel gear 52 to rotate. The meshing transmission of the two bevel gears 52 causes the threaded rod 54 to rotate in the movable groove 53. The movable seat 55 on the outer wall of the threaded rod 54 moves smoothly with the cooperation of the slide rail 57 and the slide groove 58, thereby driving the dosing tank 6 to move. When the dosing tank 6 moves, the gear 73 at the top of the stirring shaft 72 meshes with the rack frame 71, driving the stirring shaft 72 to rotate and stir. The blade 74 rotates to stir the chemicals in the dosing tank 6 to prevent sedimentation and stratification. When the dosing tank 6 reaches directly above the sewage treatment tank 1, the control valve 84 and the pump 86 are opened. The chemicals in the dosing tank 6 enter the pump 86 through the outlet pipe 83 and the extraction pipe 85. The pump 86 delivers the chemicals to the spray pipe 81. The chemicals are sprayed out through the nozzle 82 at the bottom of the spray pipe 81. Since the tilt angle of the nozzle 82 gradually increases from the inside to the outside of the sewage treatment tank 1, the chemicals are evenly covered in all areas of the sewage treatment tank 1, thus completing the entire dosing process.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
