Description

Technical Field

[0001] This utility model relates to the field of water pollution control technology, and in particular to a dosing device for water pollution control. Background Technology

[0002] Water pollution control is a process that uses various technologies, including physical, chemical, and biological methods, to reduce or remove pollutants such as organic matter, heavy metals, nitrogen and phosphorus nutrients, and pathogens from water bodies, thereby restoring the ecological function and usability of the water. It is divided into two aspects: "source control" and "end-of-pipe treatment." Source control includes pre-treatment of industrial wastewater to meet discharge standards, reducing the use of chemical fertilizers and pesticides in agriculture and recycling livestock and poultry waste, and constructing urban sewage collection networks to prevent pollutants from directly entering water bodies. End-of-pipe treatment, such as in wastewater treatment plants, uses physical methods like screens and sedimentation to remove suspended solids, and adds chemical degrading agents to degrade recalcitrant pollutants, ultimately achieving the resource utilization of wastewater and ensuring water resource security and ecological health.

[0003] Existing dosing devices mainly employ a stirring paddle structure at the end. The bottom of the dosing cylinder extends below the liquid surface inside the wastewater treatment tank. Multiple evenly distributed paddles are installed at the bottom of the stirring rod, positioned close to the bottom of the dosing cylinder. A feeding motor drives a feeding screw or auger to transport the dry powder into the dosing cylinder. The stirring motor, through the stirring rod, drives the paddles to rotate, mixing the dry powder with the wastewater to achieve dissolution.

[0004] However, this method is prone to incomplete dissolution of dry powder: after the dry powder falls into the dosing cylinder from the inlet, it tends to sink quickly to the bottom due to its own gravity. Since the paddles are positioned near the bottom of the cylinder, their rotation primarily stirs the wastewater at the bottom and surrounding areas. The dry powder, not fully dispersed, is concentrated and pushed to the bottom area, easily leading to localized dry powder accumulation. This is especially true when the amount of dry powder added is slightly larger or when the dry powder itself has poor water absorption and flowability, causing it to clump together and form lumps that the paddles cannot quickly break up, resulting in incomplete dissolution. Furthermore, there is a limited mixing range: the paddles only rotate near the bottom of the dosing cylinder, limiting the stirring effect to the area around the paddles. Areas in the wastewater pool far from the paddles are difficult to dosing. If the wastewater pool is large or the water flow is poor, there is a risk of excessively high concentrations of the agent near the paddles and insufficient concentrations further away, affecting the overall treatment effect. Therefore, we propose a dosing device for water pollution treatment to solve the problems encountered by existing technologies. Utility Model Content

The feed pipe guides the dispersed dry powder evenly into the mixing area to solve the problem of insufficient dissolution.

[0019] 2. The high-speed rotation of the paddle inside the dosing cylinder causes the water containing the agent to be sprayed out from the nozzle.

[0031] Reference Figures 1 to 4 This is the first embodiment of the present invention. This embodiment provides a dosing device for water pollution treatment, including a feed pipe 1, a dosing cylinder 2 fixed at one end of the feed pipe 1, a feeding component 3 provided inside the feed pipe 1, a stirring component 4 and a liquid concentration sensor 7 provided inside the dosing cylinder 2, and a screen component 5 provided inside the dosing cylinder 2. The screen component 5 includes a screen 51 and a brush strip 52 rotatably disposed around the screen 51. A guide pipe 53 is provided on the inner wall of the screen 51 for connecting with the screen holes of the screen 51.

[0032] The undispersed dry powder is filtered through the screen 51, and the rotating brush bar 52 pre-disperses the undispersed dry powder and sends it through the screen holes into the feed pipe 53 for discharge.

The stirring component 4 includes a second servo motor 41 and a paddle 42. The second servo motor 41 is fixed to the dosing cylinder 2. The paddle 42 is rotatably installed inside the dosing cylinder 2 via a connecting shaft, and the upper end of the connecting shaft is fixed to the output end of the second servo motor 41. Part of the paddle 42 is inside the dosing cylinder 2, and the other part of the paddle 42 is at the lower end of the dosing cylinder 2.

[0036] The liquid containing the drug is diffused by the blade 42 inside the dosing cylinder 2, and the blade 42 at the lower end of the dosing cylinder 2 is used to mix the drug at its lower end.

[0037] Specifically, the screen 51 is set in the shape of a semi-circular cap. The outer surface of the screen 51 is welded to the inner wall of the dosing cylinder 2. The lower end of the connecting shaft for mounting the blade 42 passes through the axis of the blade 42.

At the same time, the L-shaped feed pipe 53 can prevent the liquid splashed and rising from the paddle 42 from being stirred up. It can directly contact the dry powder through the sieve holes, preventing the dry powder medicine from clogging the sieve 51 and causing its filtration failure.

[0042] Example 3:

[0043] Reference Figure 1 and Figure 3 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0044] Specifically, a spray nozzle 6 is provided around the dosing cylinder 2. The spray nozzle 6 is a spray nozzle 61, which is fixed in a ring around the dosing cylinder 2.

[0045] The high-speed rotating blades 42 cause water to be ejected from the nozzle 61, expanding the mixing range.

[0046] Specifically, each nozzle 61 is connected to the dosing cartridge 2, and the nozzle 61 is set at an upward angle;

[0047] By tilting the cone head 62 upwards, the water is sprayed upwards at high speed by the blade 42, thus increasing the distance and expanding the mixing range of the agent and sewage.

[0048] Specifically, a conical head 62 is integrally provided at one end of the nozzle 61, and the conical head 62 is conical in shape;

[0049] The conical head 62 increases the pressure of the water jet, further expanding the range.

[0050] Working principle:

[0051] The working principle of the dosing device is as follows: the dry powder agent enters the feed pipe 1 from the hopper 31, the liquid concentration sensor 7 monitors the liquid concentration in the dosing cylinder 2, the controller controls the first servo motor 32 to drive the auger 33 to rotate for a certain period of time, and delivers a certain amount of dry powder into the dosing cylinder 2 through the feed pipe 1; the second servo motor 41 drives the connecting shaft to rotate, which drives the paddle 42 to rotate, and the rotation stirs and mixes the sewage and dry powder in and below the dosing cylinder 2;

[0052] The screen 51 filters the undispersed dry powder. At the same time, the connecting shaft rotates and drives the brush 52 to rotate around the semi-circular cap-shaped screen 51. The brush 52 pre-disperses the undispersed dry powder on the outer surface of the screen 51. The dispersed dry powder enters the L-shaped guide pipe 53 connected to the screen 51 through the screen holes and is then discharged.

[0053] Part of the blade 42 is inside the dosing cylinder 2 and part is at the lower end of the dosing cylinder 2. When the connecting shaft rotates, it drives the brush 52 to rotate around the semi-circular cap-shaped screen 51. At the same time, it also drives the blade 42 inside the dosing cylinder 2 to rotate, so that the water flow is sprayed out from the upwardly inclined nozzle 61 through the conical head 62, which can expand the mixing range.

[0054] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
