Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to an automatic dosing device for a wastewater treatment tank. Background Technology
[0002] Wastewater treatment is the process of removing pollutants from water bodies using physical, chemical, and biological technologies to meet discharge or reuse standards. The Fenton process is commonly used to treat high-concentration, high-color, and recalcitrant organic wastewater. The Fenton reaction utilizes ferrous ions (Fe²⁺) for treatment. 2+ Using hydrogen peroxide (H2O2) as a catalyst, it catalyzes the generation of highly oxidizing hydroxyl radicals (·OH) from hydrogen peroxide (H2O2) under acidic conditions, and efficiently degrades organic matter through a free radical chain reaction.
[0003] Currently, automatic dosing devices can be added to wastewater treatment ponds to automatically add Fenton's reagent into the ponds, which can reduce manual intervention, optimize reagent usage, and improve wastewater treatment efficiency, such as an automatic dosing system for the Fenton reaction disclosed in the prior art, CN215208653U.
[0004] However, in practical applications, existing technologies involve directly adding reagents to wastewater, causing the reagents to accumulate in one place, resulting in low mixing efficiency between the reagents and wastewater and poor treatment effects. Although existing technologies can improve the mixing efficiency between reagents and wastewater by adding an electrically driven stirring structure, this also increases costs. Utility Model Content
[0005] Therefore, this utility model provides an automatic dosing device for wastewater treatment ponds, which has a high efficiency in mixing and reacting reagents with wastewater, thereby improving wastewater treatment efficiency.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic dosing device for a wastewater treatment tank, comprising an automatic dosing component disposed at the top of a first treatment tank, and the automatic dosing component extending into the interior of the first treatment tank.
[0007] The automatic dosing assembly includes a reagent storage tank, a first dosing mechanism, and a second dosing mechanism. The reagent storage tank is fixed to the top of the first treatment tank, and the first and second dosing mechanisms are both located inside the first treatment tank for uniformly adding Fenton reagent to the wastewater.
[0008] Furthermore, the first dosing mechanism includes an annular tube, and a plurality of dosing pipes are fixed on the inner side of the annular tube, which communicate with the inner cavity of the annular tube. Each dosing pipe is fixed with a one-way valve.
[0009] Furthermore, a water guide bucket is fixed at the bottom of the first treatment tank, and the annular pipe is fixed on the inner wall of the water guide bucket. The dispensing pipe is inclined so that one of the dispensing pipes sprays Fenton reagent toward the inner wall of the water guide bucket to stir the sediment on the inner wall of the water guide bucket and improve the wastewater treatment effect.
[0010] Furthermore, the second dosing mechanism includes a spiral tube with multiple outlet pipes II fixed to the outside of the spiral tube. Each outlet pipe II is equipped with a one-way valve II. The end of the spiral tube near the annular tube is connected to the annular tube through a connecting pipe, which facilitates the uniform spraying of Fenton reagent into the first treatment tank and improves the mixing and reaction efficiency of the reagent and wastewater.
[0011] Furthermore, a dosing pipe is fixed between the outer wall of the reagent storage tank and the outer wall of the first treatment tank. One end of the dosing pipe is connected to the inside of the reagent storage tank, and the other end of the dosing pipe passes through the first treatment tank and the annular pipe and is connected to the inside of the annular pipe. A water pump for conveying Fenton's reagent in the reagent storage tank into the dosing pipe is installed inside the reagent storage tank.
[0012] Furthermore, an inlet pipe is fixed to the top of the reagent storage tank to facilitate the addition of Fenton reagent into the reagent storage tank.
[0013] Furthermore, an inlet pipe is fixed to the outer wall of the first treatment tank to facilitate the addition of wastewater into the first treatment tank.
[0014] Furthermore, a second treatment tank is provided at the bottom of the water guide hopper. The water guide hopper and the second treatment tank are fixed together by multiple pillars, and a connecting pipe is fixed between the bottom end of the water guide hopper and the top end of the second treatment tank. A valve is fixed on the connecting pipe to facilitate the discharge of the mixture of wastewater and Fenton's reagent in the first treatment tank into the second treatment tank for reaction.
[0015] This utility model has the following advantages:
[0016] 1. The reagent in the reagent storage tank can be automatically delivered to the ring tube. Then, the reagent in the ring tube is added to the first treatment tank through multiple outlet tubes. At the same time, the reagent in the ring tube also enters the spiral tube. During the flow of the reagent in the spiral tube, it is evenly sprayed into the first treatment tank through multiple outlet tubes, which helps to improve the mixing reaction efficiency of the reagent and wastewater, thereby improving the wastewater treatment efficiency.
[0017] 2. When the reagent in the annular pipe is added to the first treatment tank, the reagent is sprayed along the inner wall of the guide bucket through multiple outlet pipes, so as to stir the sediment on the inner wall of the guide bucket while adding the reagent, thereby improving the wastewater treatment effect.
[0018] 3. After the reagent is added to the wastewater in the first treatment tank, the mixture of wastewater and Fenton's reagent is discharged into the second treatment tank for reaction. At the same time, the next round of wastewater is injected into the first treatment tank and reagent is added, thereby shortening the waiting time between adjacent rounds of wastewater treatment and further improving the wastewater treatment efficiency.

[0029] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] Refer to the instruction manual appendix Figure 1-5This utility model provides an automatic dosing device for a wastewater treatment tank, including an automatic dosing component 3 installed at the top of a first treatment tank 1, and the automatic dosing component 3 extending into the interior of the first treatment tank 1. A water guide bucket 11 is fixed at the bottom of the first treatment tank 1, and an inlet pipe 12 is fixed on the outer wall of the first treatment tank 1 to facilitate the addition of wastewater into the first treatment tank 1.
[0031] The automatic dosing assembly 3 includes a reagent storage tank 31, a first dosing mechanism 32, and a second dosing mechanism 33. The reagent storage tank 31 is fixed to the top of the first treatment tank 1, and an inlet pipe 35 is fixed to the top of the reagent storage tank 31 to facilitate the addition of Fenton reagent into the reagent storage tank 31. The first dosing mechanism 32 and the second dosing mechanism 33 are both located inside the first treatment tank 1 and are used to uniformly add Fenton reagent into the wastewater.
[0032] Specifically, the first dosing mechanism 32 includes an annular tube 321 fixed on the inner wall of the water guide hopper 11. The annular tube 321 is hollow inside, and multiple dosing tubes 322 communicating with the inner cavity of the annular tube 321 are fixed on the inner side of the annular tube 321. The dosing tubes 322 are inclined so that Fenton reagent is sprayed from the dosing tubes 322 toward the inner wall of the water guide hopper 11 to stir the sediment on the inner wall of the water guide hopper 11. Each dosing tube 322 is fixed with a one-way valve 323, which is used to prevent the liquid in the dosing tube 322 from flowing back into the annular tube 321.
[0033] The second dosing mechanism 33 includes a spiral tube 331, and multiple dosing tubes 332 are fixed to the outside of the spiral tube 331. The end of the spiral tube 331 near the annular tube 321 is connected to the annular tube 321 through a connecting pipe 334 to achieve uniform spraying of Fenton reagent into the first treatment tank 1. Each dosing tube 332 is fixed with a one-way valve 333, which is used to prevent the liquid in the dosing tube 332 from flowing back into the spiral tube 331.
[0034] Next, a dosing pipe 34 is fixed between the outer wall of the reagent storage tank 31 and the outer wall of the first treatment pool 1. One end of the dosing pipe 34 is connected to the inside of the reagent storage tank 31, and the other end of the dosing pipe 34 passes through the first treatment pool 1 and the annular pipe 321 and is connected to the inside of the annular pipe 321. A water pump for conveying Fenton reagent in the reagent storage tank 31 into the dosing pipe 34 is installed inside the reagent storage tank 31.
[0035] Before treatment, Fenton's reagent is added to the reagent storage tank 31. The impurities in the wastewater are easy to settle on the inner wall of the guide hopper 11. During treatment, the wastewater is injected into the first treatment tank 1 through the inlet pipe 12. The water pump automatically transports the reagent in the reagent storage tank 31 to the ring pipe 321 through the dosing pipe 34. Then, the reagent in the ring pipe 321 is sprayed into the guide hopper 11 through multiple outlet pipes 322. At the same time, the reagent is sprayed along the inner wall of the guide hopper 11, so that the sediment on the inner wall of the guide hopper 11 can be stirred while the reagent is added to the first treatment tank 1, thereby improving the wastewater treatment effect.
[0036] Then, the reagent in the annular tube 321 enters the spiral tube 331 through the connecting tube 334. The reagent flows from the bottom to the top of the spiral tube 331. During the flow of the reagent in the spiral tube 331, it is evenly sprayed into the first treatment tank 1 through multiple outlet tubes 332 on the spiral tube 331, which helps to improve the reaction efficiency between the reagent and the wastewater, thereby improving the wastewater treatment efficiency.
[0037] Fenton's reagent needs to react with wastewater for a period of time after being added to achieve the desired water treatment effect. If the next round of wastewater treatment is carried out only after the first round is completed, the waiting time is too long and the wastewater treatment efficiency is low. Therefore, if... Figure 1 As shown, the present invention has a second treatment pool 2 at the bottom of the water guide bucket 11. The water guide bucket 11 and the second treatment pool 2 are fixed together by multiple support columns 4. A connecting pipe 13 is fixed between the bottom end of the water guide bucket 11 and the top end of the second treatment pool 2. A valve is fixed on the connecting pipe 13. The valve can be a manual valve or an electric valve.
[0038] After Fenton's reagent is added to the wastewater in the first treatment tank 1, the valve on the connecting pipe 13 is opened to discharge the mixture of wastewater and Fenton's reagent into the second treatment tank 2. Then the valve is closed, and the next round of wastewater is injected into the first treatment tank 1 with Fenton's reagent added. At the same time, the wastewater in the second treatment tank 2 reacts with Fenton's reagent. After the reaction between the wastewater and Fenton's reagent in the second treatment tank 2 is completed, it is discharged from the second treatment tank 2. Then the mixture of wastewater and Fenton's reagent in the first treatment tank 1 is discharged into the second treatment tank 2, and the next round of wastewater is injected into the first treatment tank 1 with Fenton's reagent added, and so on. This shortens the waiting time between adjacent rounds of wastewater treatment and improves the wastewater treatment efficiency.
[0039] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
