Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, specifically to a chemical dosing coagulation and sedimentation device. Background Technology

[0002] Electroadsorption heavy metal recovery is a method for recovering heavy metals from wastewater using electroadsorption technology. It is an effective water treatment method. Electroadsorption technology uses an electric field to concentrate heavy metal ions in the water on the electrode surface, and then converts them into metal deposits through electrochemical deposition, thereby achieving heavy metal recovery and wastewater treatment. In the electroadsorption heavy metal recovery process, chemical coagulation is a crucial step. Specifically, coagulation involves adding coagulants and flocculants to the wastewater, causing suspended solids and colloidal particles to aggregate into larger particles, which are then removed through sedimentation or filtration. Therefore, a chemical coagulation sedimentation device is needed. However, current chemical coagulation sedimentation devices still have the following shortcomings:

[0003] For example, patent document CN213253423U discloses a sedimentation device for water treatment. This sedimentation device for water treatment is used for sewage treatment and has multi-stage filtration, flocculation removal, and multi-stage sedimentation functions. It features good filtration effect and high sedimentation efficiency, which can effectively improve the efficiency and effect of sewage treatment and has low treatment cost. However, it is not convenient to spray coagulant evenly, which can easily lead to insufficient reaction between coagulant and wastewater, resulting in poor coagulation and sedimentation effect.

[0004] Therefore, in view of this, we have studied and improved the existing structure to address its shortcomings, and proposed a chemical dosing coagulation and sedimentation device. Utility Model Content

[0016] 1. This utility model incorporates a coagulation assembly, which includes a hydraulic push rod, a servo motor, a hollow connecting rod, a dosing port, a sealing cap, a connecting cavity, a hollow connecting plate, and a dispensing port. In use, liquid coagulant is injected into the hollow connecting rod through the dosing port, allowing the coagulant to flow into the connecting cavity and the hollow connecting plate. The servo motor is then activated, causing the hollow connecting rod to rotate, resulting in the coagulant being evenly dispersed into the water from the dispensing port. After the coagulant is dispensed, the hydraulic push rod is activated, moving the hollow connecting plate downwards into the water. The servo motor is then activated again, causing it to rotate the connecting cavity and the hollow connecting plate via the hollow connecting rod, thus thoroughly mixing the coagulant and water. This allows the device to achieve uniform dispensing and continuous, thorough mixing of the coagulant solution and wastewater, thereby improving coagulation efficiency.

The purification filter further intercepts sediment in the water, while the activated carbon filter adsorbs smaller impurities and harmful substances. The pre-filtered wastewater is discharged through the drain valve for subsequent treatment. Thus, this device can pre-filter wastewater after coagulation and sedimentation for further processing.

The output end of the servo motor 402 is connected to the hollow connecting rod 403 through a coupling. A dosing port 404 is provided on the front side of the upper end of the hollow connecting rod 403, and a sealing cover 405 is engaged and connected to the front side of the dosing port 404. A connecting cavity 406 is installed at the bottom of the hollow connecting rod 403.

[0025] The specific operation is as follows: During use, liquid coagulant is injected into the hollow connecting rod 403 through the dosing port 404, allowing the liquid coagulant to pass into the connecting cavity 406 and the hollow connecting plate 407. The servo motor 402 is started, causing the servo motor 402 to drive the hollow connecting rod 403 to rotate, so that the coagulant is evenly dispersed into the water from the dosing port 408. After the coagulant is dispersed, the hydraulic push rod 401 is started to move the hollow connecting plate 407 downward into the water. Then, the servo motor 402 is started again, causing the servo motor 402 to drive the connecting cavity 406 and the hollow connecting plate 407 to rotate through the hollow connecting rod 403, so as to fully mix the coagulant and water.

[0026] Please refer to Figure 1 , Figure 3 and Figure 4Hollow connecting plates 407 are provided on both sides of the connecting cavity 406, and a medicine outlet 408 is installed on the lower surface of the hollow connecting plate 407. A fixed base plate 5 is installed at the bottom of the supporting column 2, and the right end of the upper surface of the fixed base plate 5 is set on the fixed column 6. A drain valve 7 is installed at the bottom of the coagulation sedimentation tank 1, and a collection tank 8 is installed at the bottom of the drain valve 7. The collection tank 8 is an integrated structure, and a collection mesh bag 9 is provided inside the collection tank 8. A filter assembly 10 for filtration is provided at the top of the supporting column 2, and the filter assembly 10 includes a filter tank 1001, a dirt removal filter 1002, an activated carbon filter 1003, a drain valve 1004, a liquid pump 1005, a drain pipe 1006, and a liquid suction pipe 1007. The filter tank 1001 is located at the top of the supporting column 2, and the filter tank 1001 is located inside the filter tank 1001. A filter screen 1002 is installed at the top, an activated carbon filter screen 1003 is installed at the lower end of the filter tank 1001, a drain valve 1004 is installed at the lower right end of the filter tank 1001, a liquid pump 1005 is installed at the top of the filter tank 1001, a drain pipe 1006 is connected to the right end of the liquid pump 1005, and the lower end of the drain pipe 1006 is connected to the upper side of the filter tank 1001. A liquid pump 1007 is connected to the left end of the liquid pump 1005, and the left end of the liquid pump 1007 passes through the lower right end of the impurity collection tank 8 and extends into the impurity collection tank 8. A water pipe 11 is connected to the lower end of the drain valve 1004, and a high-pressure water pump 12 is installed at the right end of the water pipe 11. A water delivery pipe 13 is connected to the right end of the water pump 12, and an electro-adsorption device 14 is installed at the upper end of the water delivery pipe 13.

[0027] The specific operation is as follows: After coagulation, let it stand for a period of time to settle. Open the drain valve 7 to let the wastewater fall into the collection tank 8. The sediment in the water is intercepted and filtered by the collection mesh bag 9 in the collection tank 8. Start the pump 1005 to pump the wastewater out of the collection tank 8 through the pump pipe 1007 and transport it to the filter tank 1001 through the drain pipe 1006. The sediment in the water is further intercepted by the impurity removal filter 1002. The activated carbon filter 1003 can adsorb smaller impurities and harmful substances. The wastewater after preliminary filtration is discharged through the drain valve 1004 for subsequent treatment. Start the high-pressure water pump 12 to pump the water after preliminary filtration through the connecting water pipe 11 and transport the water to the electro-adsorption device 14 through the water delivery pipe 13. The electro-adsorption device 14 achieves the effect of purifying the wastewater and recovering heavy metals.

[0028] In summary, as Figures 1 to 4As shown, in use, this dosing coagulation and sedimentation device first injects liquid coagulant into the hollow connecting rod 403 through the dosing port 404, allowing the liquid coagulant to flow into the connecting cavity 406 and the hollow connecting plate 407. Then, the servo motor 402 is started, causing it to rotate the hollow connecting rod 403, causing the coagulant to be evenly dispersed into the water from the outlet 408. After the coagulant is dispersed, the hydraulic push rod 401 is activated, moving the hollow connecting plate 407 downwards into the water. Then, the servo motor 402 is activated again, causing it to rotate the connecting cavity 406 and the hollow connecting plate 407 via the hollow connecting rod 403, thus dispersing the coagulant and water... After thorough stirring and coagulation, the mixture is allowed to stand for a period of time to settle. The drain valve 7 is then opened, allowing the wastewater to fall into the collection tank 8. The collection mesh bag 9 inside the collection tank 8 intercepts and filters the sediment in the water. The pump 1005 is then started, drawing the wastewater from the collection tank 8 through the pumping pipe 1007 and transporting it to the filter tank 1001 through the drain pipe 1006. The sediment in the water is further intercepted by the impurity removal filter 1002, and the activated carbon filter 1003 adsorbs smaller impurities and harmful substances. The pre-filtered wastewater is discharged through the drain valve 1004 for subsequent treatment. (The electro-adsorption device 14 is model NTK-2000T.)
