Description

Technical Field

[0001] This application relates to the technical field of sewage treatment, and particularly relates to a chemical sewage treatment dosing device. Background Art

[0002] In the existing chemical sewage treatment process, dosing devices play a crucial role. They add specific treatment agents to the sewage to promote the decomposition, precipitation or transformation of pollutants in the sewage, thereby achieving the purpose of purifying water quality.

[0003] Specifically, most of the dosing devices for sewage treatment widely used in the market currently adopt fixed-position spray heads or nozzles, which can only spray treatment agents on the surface layer or a certain fixed depth of the sewage. The limitation of this method is that it takes a long time for the treatment agent to penetrate from the surface layer to the entire water body, and the penetration process may be affected by various factors such as sewage flow, temperature, pH value, etc., resulting in uneven distribution of the treatment agent and poor mixing effect. In addition, since the treatment agent cannot quickly and evenly diffuse to all levels of the sewage, the reaction time between pollutants in the sewage and the treatment agent is prolonged, which not only reduces the treatment efficiency but also may increase the burden of subsequent treatment processes.

[0004] In view of the above problems, a dosing device for chemical sewage treatment is now designed. Utility Model Content

[0005] The embodiments of this application provide a dosing device for chemical sewage treatment to solve the problem that in the related art, most of the dosing equipment for sewage treatment adopts fixed-position spray heads or nozzles, which generally can only inject treatment agents into the surface layer or a certain fixed depth of the sewage, resulting in uneven distribution of the treatment agent and reduced treatment efficiency.

The inlet of the pump body is communicated with the liquid storage tank. A delivery pipe is arranged at the outlet of the pump body, and the other end of the delivery pipe is communicated with the spraying network pipe. The pump body is used for sending the treatment agent inside the liquid storage tank into the spraying network pipe;

[0009] A lifting mechanism is provided on the treatment pool. The lifting mechanism is used to drive the pesticide spraying network pipe to lift and lower, and inject the treatment agent into the interior of the cavity at different depths through the injection ports on the pesticide spraying network pipe.

[0010] In some embodiments, the pesticide spraying network pipe includes a rectangular frame plate. There is a liquid storage cavity inside the rectangular frame plate. A number of circular pipes are arranged inside the rectangular frame plate. The circular pipes are all communicated with the liquid storage cavity. The number of circular pipes are distributed along the length direction of the rectangular frame plate;

[0011] A number of the injection ports are opened on the circular pipes.

[0012] In some embodiments, the liquid storage tank includes a tank body for storing the treatment agent. A stirrer is provided on the tank body. The stirrer is used to stir the treatment agent inside the tank body.

[0013] In some embodiments, the conveying pipe includes a liquid supply pipe and a hose that are communicated with each other. The other end of the liquid supply pipe is communicated with the liquid outlet of the pump body. The other end of the hose is communicated with the circular pipe.

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0024] The embodiment of the present application provides a chemical sewage treatment dosing device, which can solve the problem that in the related art, the dosing equipment for sewage treatment mostly uses fixed-position nozzles or spray heads, and generally can only inject treatment agents into the surface layer or a certain fixed depth of the sewage, resulting in uneven distribution of the treatment agents and reduced treatment efficiency.

[0025] Please refer to Figures 1 - 3 , a chemical sewage treatment dosing device includes; a treatment pool 1, the interior of the treatment pool 1 has a cavity for accommodating sewage, and a liquid injection mechanism 2 for adding treatment agents into the cavity is provided on the treatment pool 1;

[0026] The liquid injection mechanism 2 includes a spraying network pipe 21, a liquid storage tank 22 and a pump body 23 slidably arranged inside the cavity. A plurality of spraying ports 3 for the outflow of treatment agents are provided on the spraying network pipe 21. The liquid storage tank 22 is used for storing treatment agents. The liquid inlet of the pump body 23 is communicated with the liquid storage tank 22. A delivery pipe 24 is provided at the liquid outlet of the pump body 23. The other end of the delivery pipe 24 is communicated with the spraying network pipe 21. The pump body 23 is used for feeding the treatment agents inside the liquid storage tank 22 into the spraying network pipe 21;

[0027] A lifting mechanism 4 is provided on the treatment tank 1. The lifting mechanism 4 is connected to the spraying network pipe 21 and is used to drive the spraying network pipe 21 to lift and lower, and the treatment agent is injected into different depths inside the cavity through the injection ports 3 on the spraying network pipe 21. The liquid inlet of the pump body 23 is communicated with the liquid storage tank 22 through a metal pipe.

[0028] First, the required treatment agent is injected into the liquid storage tank 22. The liquid storage tank 22 serves as a storage container for the treatment agent to ensure that the treatment agent maintains its original chemical properties and stability before use. When it is necessary to add the treatment agent to the treatment tank 1, the pump body 23 is started. The pump body 23 extracts the treatment agent through the metal pipe between its liquid inlet and the liquid storage tank 22 and pumps out the treatment agent through its liquid outlet;

[0029] The pumped treatment agent is transported to the spraying network pipe 21 through the delivery pipe 24. The spraying network pipe 21 evenly sprays the treatment agent inside the cavity of the treatment tank 1. At the same time, driven by the lifting mechanism 4, the spraying network pipe 21 can move up and down inside the cavity of the treatment tank 1, so as to realize injecting the treatment agent into the sewage at different depths.

[0030] Through the coordinated use of the spraying network pipe 21, the liquid storage tank 22, the pump body 23 and the lifting mechanism 4, the treatment agent can be evenly and quickly injected into different depths of the sewage, greatly improving the mixing effect of the treatment agent and the sewage. Since the treatment agent can quickly and evenly diffuse to each layer of the sewage, the pollutants in the sewage can react with the treatment agent faster, thus improving the overall treatment efficiency.

[0031] The design of this device allows for flexibly adjusting the lifting height and injection volume of the spraying network pipe 21 according to different sewage treatment requirements to achieve effective treatment of different types and concentrations of sewage.

[0032] By optimizing the mixing effect and shortening the reaction time, this device can reduce the energy consumption in the sewage treatment process to a certain extent, which conforms to the environmental protection concept of energy conservation and emission reduction.

[0033] Specifically, as Figure 3 shown, the spraying network pipe 21 in this implementation scheme includes a rectangular frame plate 211. There is a liquid storage cavity inside the rectangular frame plate 211. A number of round pipes 212 are arranged inside the rectangular frame plate 211. The round pipes 212 are all communicated with the liquid storage cavity. The number of the round pipes 212 is distributed along the length direction of the rectangular frame plate 211; A number of the injection ports 3 are opened on the round pipes 212. A filter screen piece is embedded on the injection port 3.

[0034] The rectangular frame plate 211 serves as the main structure of the spraying network pipe 21. A liquid storage cavity is designed inside the rectangular frame plate 211 for temporarily storing the treatment agent transported from the delivery pipe 24.

[0035] Inside the rectangular frame plate 211, a number of round tubes 212 are distributed along its length direction, and these round tubes 212 are all connected to the liquid storage cavity. The round tubes 212 serve as the distribution channels for the treatment agent and can evenly distribute the treatment agent in the liquid storage cavity to each injection port 3.

[0036] The injection port 3 is opened on the round tube 212 and is the outlet for the treatment agent to spray from the medicine spraying network tube 21 into the sewage. By reasonably designing the size, quantity, and distribution of the injection port 3, the uniform spraying of the treatment agent in the sewage can be achieved.

[0037] A filter screen is embedded in the injection port 3. This design has two main functions: one is to prevent external impurities from entering the inside of the medicine spraying network tube 21 and affecting the treatment effect; the other is to play a certain role in flow equalization. The filter screen disperses the sprayed treatment agent, making the sprayed treatment agent more delicate and uniform.

[0038] Through the distribution function of the liquid storage cavity and the round tubes 212 inside the rectangular frame plate 211, and the uniform distribution of the injection ports 3, the medicine spraying network tube 21 can achieve the uniform spraying of the treatment agent in the sewage. This uniformity helps to improve the mixing effect of the treatment agent and the sewage, ensuring that all parts of the sewage can be fully treated.

[0039] In one embodiment, as Figure 4 shown, the liquid storage tank 22 includes a tank body 221 for storing the treatment agent, and a stirrer 222 is arranged on the tank body 221. The stirrer 222 is used to stir the treatment agent inside the tank body 221.

[0040] The tank body 221 is used to store the treatment agent to be injected into the treatment pool 1. The tank body 221 should have good sealing performance and corrosion resistance to ensure that the treatment agent will not leak or deteriorate during storage.

[0041] The stirrer 222 is installed on the tank body 221 and extends deep into the tank body. Its main function is to stir the treatment agent inside the tank body 221 regularly or continuously to prevent the treatment agent from precipitating, stratifying, or caking due to long-term standing.

[0042] Preferably, in this implementation scheme, a liquid injection pipeline is arranged on the liquid storage tank 22, and the liquid injection pipeline is connected to an external liquid supply pipe.

[0043] One or more liquid injection pipelines are arranged on the liquid storage tank 22. One end of these pipelines is connected to the top, side, or bottom of the liquid storage tank 22, and the other end is connected to an interface connected to the external liquid supply pipe. The liquid injection pipeline usually has an appropriate diameter and material to ensure that the treatment agent can be injected into the liquid storage tank 22 smoothly and quickly, maintaining an adequate amount of treatment agent inside the liquid storage tank 22.

[0044] The treatment agent in this implementation plan refers to a chemical substance or mixture used in a specific treatment process. Common treatment agents include:

[0045] Flocculants, which are used to remove suspended solids, colloids and other impurities in water and improve the clarity of water. Coagulant aids: Used in conjunction with flocculants to enhance the coagulation effect and improve the sedimentation performance. Disinfectants: Used to kill pathogenic microorganisms in water to ensure the hygienic safety of water. Common disinfectants include chlorine, sodium hypochlorite, chlorine dioxide, etc. This is a technology and will not be elaborated here.

[0046] It should be noted that the delivery pipe 24 includes a liquid supply pipe 241 and a hose 242 that are interconnected. The other end of the liquid supply pipe 241 is connected to the liquid outlet of the pump body 23, and the other end of the hose 242 is connected to the circular pipe 212. A fixing block for supporting the liquid supply pipe 241 is provided on the treatment tank 1.

[0047] The liquid supply pipe 241 is the rigid part of the delivery pipe 24, and one end of it is tightly connected to the liquid outlet of the pump body 23. When the pump body 23 works, the treatment agent in the liquid storage tank 22 is pumped out and transported to the next part through the liquid supply pipe 241.

[0048] The hose 242 is the flexible part of the delivery pipe 24. One end of it is interconnected with the other end of the liquid supply pipe 241, and the other end is connected to the circular pipe 212 in the spraying network pipe 21. The design of the hose 242 enables the delivery pipe 24 to flexibly follow the lifting movement of the spraying network pipe 21 without being restricted by a rigid connection. This flexibility ensures that the spraying network pipe 21 can move freely in the treatment tank 1, thereby realizing the injection of the treatment agent into the sewage at different depths.

[0049] Specifically, as Figure 2 shown, the lifting mechanism 4 in this implementation plan includes mounting plates 41 oppositely arranged on the treatment tank 1. An electric push rod 42 is arranged between the two mounting plates 41. A weighing pan 43 is arranged at the end of the piston rod of the electric push rod 42. A plurality of transmission rods 44 are arranged at the bottom of the weighing pan 43, and the other ends of the transmission rods 44 are connected to the spraying network pipe 21. The number of the lifting mechanisms 4 can be two, and they are oppositely arranged on the treatment tank

[0050] The number of the lifting mechanisms 4 is two, and they are oppositely arranged on the treatment tank 1. This layout helps to realize the stable lifting and lowering of the spraying network pipe 21, reducing the inclination or distortion caused by unilateral force. At the same time, the two lifting mechanisms 4 can work together to improve the overall lifting efficiency and stability.

[0051] When it is necessary to inject a treatment agent into the sewage in the treatment pool 1, the electric push rod 42 is activated, its piston rod retracts, and the weighing pan 43 and the transmission rod 44 are pushed down. The transmission rod 44 transmits the force to the medicine spraying network pipe 21, causing it to descend and enter the sewage accordingly. As the medicine spraying network pipe 21 goes deeper, the treatment agent is evenly sprayed into the sewage through the injection ports 3, thereby completing a medicine adding operation for different depths in the sewage.

[0052] After a certain depth of treatment is completed, the electric push rod 42 moves in the reverse direction, the piston rod of the electric push rod 42 extends, and the medicine spraying network pipe 21 is lifted upward to completely move out of the sewage. Subsequently, the steps are repeated, and in this way, the medicine adding operation for different levels of sewage is completed.

[0053] It should be noted that a waste water pipe 5 for the inflow of sewage is provided on the treatment pool 1, and a drainage pipe 6 for the outflow of sewage is provided at the bottom of the side wall of the treatment pool 1. The other end of the drainage pipe 6 is connected to a second pump body, and the water outlet of the second pump body is connected to an external pipe.

[0054] The waste water pipe 5 is the inlet part of the treatment pool 1 and is used to introduce the sewage to be treated from the outside into the treatment pool. The waste water pipe 5 is usually provided above or on the side of the treatment pool 1.

[0055] The drainage pipe 6 is the outlet part of the treatment pool 1 and is used to discharge the treated sewage or sludge from the treatment pool. The drainage pipe 6 is usually provided at the bottom of the side wall of the treatment pool 1 to facilitate the discharge of the sludge deposited at the bottom of the pool or the treated sewage.

[0056] The main function of the second pump body is to provide power for the drainage pipe 6, pump out the sewage in the treatment pool 1, and transport it to the subsequent treatment equipment.
