Description

Technical Field

[0002] Wastewater treatment refers to the process of purifying wastewater using physical, chemical, and biological methods to meet the water quality requirements for discharge into natural water bodies or reuse. In the flocculation stage of wastewater treatment, the proper addition of flocculants is crucial.

[0003] However, traditional quantitative dosing devices for wastewater flocculation treatment typically only add flocculants to the upper layer of wastewater, resulting in a large concentration of flocculants in the upper water layer at the initial stage. This concentrated dosing method prevents wastewater at different levels from contacting the flocculants in a timely and uniform manner, affecting the flocculation effect. Furthermore, to ensure that the flocculants are fully mixed with wastewater at each level, a lengthy stirring process is required. This not only increases the equipment's operating time and energy consumption but also reduces the efficiency of wastewater treatment and prolongs the entire treatment cycle.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0023] Example 1: Please refer to Figures 1-6 As shown, this utility model provides a drug quantitative dosing device, comprising: The processing tank 1 has a radar-type liquid level sensor 35 fixedly installed on the right side of the top of the processing tank 1. The middle of the bottom of the processing tank 1 is movably connected to the rotating shaft 16 through the bearing. The middle of the rotating shaft 16 is fixedly connected to the stirring blade 17. The top of the rotating shaft 16 is fixedly installed with the coupling 14. The top of the coupling 14 is fixedly installed with the drive motor 9. A medicine tank 5 has a PLC controller 6 fixedly installed on the upper end of the front surface of the medicine tank 5. A plunger metering pump 13 is fixedly installed on the left end of the front surface of the medicine tank 5 through a pipe. An annular conduit 7 is fixedly installed on the output end of the plunger metering pump 13 through a pipe. A dosing pipe 18 is fixedly connected to the bottom of the annular conduit 7. There are three dosing pipes 18. A through hole 29 is opened at the lower end of the dosing pipe 18. An electromagnetic clutch 21 is fixedly installed at the bottom of the rotating shaft 16. A first bevel gear 22 is fixedly installed at the output end of the electromagnetic clutch 21. A second bevel gear 23 meshes with the right end of the first bevel gear 22. A rotating rod 24 is fixedly installed at the middle end of the right side of the second bevel gear 23. A U-shaped rod 26 is fixedly connected to the right side of the rotating rod 24. A connecting rod 12 is movably connected to the middle end of the U-shaped rod 26 through a bearing. A moving rod 11 is movably connected to the upper end of the connecting rod 12 through a bearing. The left side of the moving rod 11 is fixedly connected to the right side of the annular guide tube 7. The output of the radar level sensor 35 is electrically connected to the input of the PLC controller 6. The output of the PLC controller 6 is electrically connected to the input of the plunger metering pump 13. The output of the PLC controller 6 is electrically connected to the input of the drive motor 9. The output of the PLC controller 6 is electrically connected to the input of the electromagnetic clutch 21.

[0024] In this technical solution, the radar-type liquid level sensor 35 monitors the sewage level inside the treatment tank 1 and transmits the liquid level data to the PLC controller 6 for processing and analysis. The PLC controller 6 then controls the drive motor 9 and the plunger metering pump 13 to operate. The plunger metering pump 13 extracts flocculant from the reagent tank 5 and delivers it through the annular conduit 7 into the dosing pipe 18. Simultaneously, it adds the flocculant to the sewage inside the treatment tank 1 through the through-hole 29. Meanwhile, the drive motor 9, through the coupling 14 and the rotating shaft 16, drives the stirring blades 17 to rotate, causing the stirring blades 17 to rapidly mix the sewage and flocculant. The rotation of the rotating shaft 16, through the input end of the electromagnetic clutch 21, drives the first bevel gear 22 connected to the output end to rotate. The rotation of the first bevel gear 22 then drives the second bevel gear... Gear 23, rotating rod 24, and U-shaped rod 26 rotate. The rotation of U-shaped rod 26 can push moving rod 11, annular conduit 7, and dosing pipe 18 to reciprocate vertically through connecting rod 12. Under the action of the dosing pipe 18, flocculant can be evenly added to different levels of sewage through through hole 29, thereby improving the uniformity of flocculant dosing and effectively reducing the time required for mixing sewage and flocculant, thus greatly improving the efficiency and quality of sewage treatment. When the amount of flocculant added meets the flocculation treatment requirements of the current water level sewage, PLC controller 6 will control plunger metering pump 13 to stop running. While completing the quantitative dosing of flocculant, it can also control the input and output ends of electromagnetic clutch 21 to separate, thereby effectively cutting off the power transmission between rotating shaft 16 and first bevel gear 22, ensuring that the mixing of sewage and flocculant can be carried out separately after the agent is added, reducing the energy consumption caused by power transmission.

[0025] It should be noted that, firstly, the radar-type liquid level sensor 35, as existing technology, is a non-contact level measuring device that uses electromagnetic waves to measure the height of liquid or solid materials. It calculates the distance between the material and the sensor by emitting radar waves and receiving reflected signals, thereby determining the liquid or material level. Furthermore, the radar-type liquid level sensor 35 is electrically connected to the PLC controller 6 (refer to patent CN213506664U). Secondly, the plunger-type metering pump 13, as existing technology, is a positive displacement reciprocating pump that precisely delivers a fixed quantity of liquid through the reciprocating motion of the plunger. It is widely used in industrial processes requiring high precision, high pressure, or low flow rate control. The metering pump 13 is electrically connected to the PLC controller 6 (refer to patent CN213775331U); third, the electromagnetic clutch 21, as prior art, is an automatic control device that uses electromagnetic force to realize the transmission or disconnection of power. It is widely used in mechanical transmission systems. Its core feature is that it controls the power transmission by engaging when energized and disengaging when de-energized. The electromagnetic clutch 21 is electrically connected to the PLC controller 6 (refer to patent CN110656877B); fourth, the drive motor 9, as prior art, is electrically connected to the PLC controller 6 in actual use (refer to patent CN222250524U).

[0026] Example 2: Based on Example 1, this utility model is as follows... Figures 1-5 As shown, a stirring rod 27 is movably connected to the middle of the inner cavity of the medicine tank 5 via a bearing. The left side of the stirring rod 27 is fixedly connected to the upper right side of the U-shaped rod 26. A second rubber ring 28 is fixedly installed at the middle of the left side of the medicine tank 5. The surface of the second rubber ring 28 contacts the surface of the stirring rod 27. A filling hopper is fixedly connected to the right end of the top of the medicine tank 5. A transparent observation plate is fixedly connected to the middle of the front surface of the medicine tank 5.

[0027] In this technical solution, when the flocculant is added, the rotation of the U-shaped rod 26 drives the stirring rod 27 to rotate, which in turn stirs and mixes the flocculant inside the reagent tank 5, effectively improving the quality of flocculant addition. The addition hopper facilitates the addition of the prepared flocculant into the reagent tank 5, and the transparent observation plate allows personnel to easily observe the liquid level inside the reagent tank 5.

[0028] Example 3: Based on Example 1, this utility model is as follows Figure 6As shown, a support rod 31 is fixedly connected to the surface of the through hole 29. A push rod 34 is slidably connected to the middle end of the support rod 31. A pressure spring 30 is fixedly connected between the surface of the push rod 34 and the surface of the support rod 31. A sealing plate 33 is fixedly connected to one side of the push rod 34. The surface of the sealing plate 33 contacts the outer surface of the dosing tube 18. A rubber pad 32 is fixedly installed around the sealing plate 33. The surface of the rubber pad 32 contacts the outer surface of the dosing tube 18.

[0029] In this technical solution, when the flocculant is added, during the process of the plunger metering pump 13 conveying the flocculant, the sealing plate 33 is displaced and detached from the surface of the dosing pipe 18 under the action of pressure, and the push rod 34 moves to compress the pressure spring 30 on the support rod 31, so that the flocculant can be added to the sewage through the through hole 29. After the flocculant is added, when the plunger metering pump 13 stops running, the push rod 34 and the sealing plate 33 can move under the tension of the pressure spring 30, so that the sealing plate 33 can be tightly attached to the surface of the dosing pipe 18, and the area around the through hole 29 can be sealed. This prevents a large amount of impurities from entering the through hole 29 and the inside of the dosing pipe 18 during the subsequent sewage flocculation process, which would cause blockage and ensure normal use in the later stage. The setting of the rubber gasket 32 ​​improves the sealing effect between the sealing plate 33 and the dosing pipe 18.

[0030] Example 4: Based on Example 1, this utility model is as follows Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a guide sleeve 15 is fixedly connected to the top of the processing box 1. There are three guide sleeves 15. Guide balls are movably connected between the inner cavity of the guide sleeve 15 and the upper end of the outer surface of the feeding pipe 18.

A support plate 25 is fixedly connected to the right end of the bottom of the outer surface of the processing box 1. The surface of the rotating rod 24 is movably connected to the support plate 25 through a bearing. At the lower end of 5, a guide rod 10 is fixedly connected to the right end of the top of the outer surface of the treatment box 1. The left end of the moving rod 11 is slidably connected to the left end of the guide rod 10. A water inlet pipe 2 is fixedly connected to the upper end of the front surface of the treatment box 1. A water inlet valve is fixedly installed at the right end of the water inlet pipe 2. A discharge pipe 3 is fixedly connected to the lower end of the front surface of the treatment box 1. A discharge valve is fixedly installed at the right end of the discharge pipe 3. Columns 4 are fixedly connected to the four sides of the bottom of the outer surface of the treatment box 1. A load-bearing base plate is fixedly connected between the bottoms of the four columns 4. A first rubber ring 20 is fixedly installed at the middle of the bottom of the treatment box 1. The surface of the first rubber ring 20 contacts the lower end of the rotating shaft 16.

[0031] In this technical solution, the guide sleeve 15 and guide balls are used to vertically guide the dosing pipe 18 and the annular conduit 7, preventing them from tilting due to force. The mounting bracket 8 is used to support and fix the drive motor 9. The mounting rod 19 is used to support and fix the electromagnetic clutch 21. The support plate 25 is used to support the rotating rod 24, preventing it from tilting due to force. The guide column 10 is used to guide the moving rod 11, preventing it from tilting due to force. The inlet pipe 2, inlet valve, outlet pipe 3, and outlet valve facilitate the input of wastewater into the treatment tank 1 and its discharge to subsequent treatment equipment. The column 4 and the load-bearing base plate support the bottom of the treatment tank 1. The first rubber ring 20 effectively improves the sealing between the rotating shaft 16 and the treatment tank 1.
