Description

Technical Field

[0001] This utility model relates to the technical field of sedimentation tanks, and in particular to a novel modular magnetic coagulation sedimentation tank. Background Technology

[0002] Coagulation sedimentation tanks are a type of sedimentation tank used in water supply and drainage. The coagulation process is one of the most basic and crucial processes in industrial water and domestic sewage treatment. By adding chemicals to the water, particles that are difficult to settle can aggregate to form colloids, which then combine with impurities in the water to form larger flocs. Magnetic coagulation sedimentation technology adds magnetic heavy media powder as flocculant nuclei to the ordinary coagulation sedimentation process, thereby accelerating floc formation and achieving faster sedimentation speed and better sedimentation effect—a new generation of sedimentation technology. Existing technology announcement number CN221217372U proposes a novel coagulation sedimentation tank, including a tank body with an internal retrieval structure for removing flocs. A pre-embedded pipe is fixed inside the bottom wall of the tank body, and multiple aeration pipes are fixed to the side walls of the pre-embedded pipes, with the tops of the aeration pipes extending into the tank body. An air pump connected to the pre-embedded pipe is fixed to the outer wall of the tank body, and two uprights are fixed to the top two sides of the tank body. However, it is inconvenient to collect the flocculation formed by magnetic attraction during use, and the magnetic powder is easily lost. At the same time, it is impossible to add and mix the chemicals in the water. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a novel modular magnetic coagulation sedimentation tank that can stir and mix the reagents and magnetic powder, improve the mixing effect, ensure the sewage treatment effect, and adsorb the flocculation formed by the combination of magnetic powder and coagulant, thus avoiding the loss of magnetic powder.

[0004] This utility model discloses a novel modular magnetic coagulation sedimentation tank, comprising a sedimentation tank body, multiple support legs, a dosing module, a mixing module, a magnetic adsorption module, an effluent module, and a cleaning module. Support legs are fixedly installed at the four corners of the bottom of the sedimentation tank body, which slopes inwards towards the center. A dosing module is installed on the upper right side wall of the sedimentation tank body, and a mixing module is installed inside the dosing module. A magnetic adsorption module is installed on the right side of the sedimentation tank body, and an effluent module is installed on the left side. A cleaning module is also installed inside the sedimentation tank body. Wastewater is fed into the dosing module, where chemicals and magnetic powder are added. The mixing module stirs and mixes the chemicals and magnetic powder, improving the mixing effect and ensuring wastewater treatment efficiency. The magnetic adsorption module adsorbs the flocculated particles formed by the magnetic powder and coagulant, preventing magnetic powder loss and significantly improving the adsorption effect of impurities in the sedimentation tank body. The mixed wastewater is fed back into the sedimentation tank body, where impurities settle to the bottom. The effluent module discharges the upper layer of clear water, and the cleaning module cleans and empties the bottom of the sedimentation tank body.

[0005] Preferably, the dosing module includes a support base, a mixing tank, an inlet pipe, a dosing cylinder, a rotating shaft, a servo motor, multiple sets of dispensing plates, and a feeding pipe. The support base is fixedly installed on the right side wall of the sedimentation tank body. The mixing tank is installed on top of the support base, and the inlet pipe is connected to the upper part of the right side wall of the mixing tank. The dosing cylinder is installed on top of the mixing tank, and a feeding hopper is provided on the top of the dosing cylinder. The output end of the dosing cylinder is connected to the feeding pipe, which communicates with the inside of the mixing tank. The rotating shaft is rotatably installed in the middle of the dosing cylinder, and the input end of the rotating shaft is connected to the output end of the servo motor. Multiple dispensing plates are axially installed on the outer wall of the rotating shaft. Wastewater is input into the mixing tank through the inlet pipe, and the reagents and magnetic powder are added into the dosing cylinder through the feeding hopper. The servo motor is started, which drives the dispensing plates to rotate through the rotating shaft, pushing the reagents and magnetic powder and feeding them evenly into the mixing tank through the feeding pipe, so that the reagents and magnetic powder are mixed with the wastewater, which is convenient for use.

[0006] Preferably, the mixing module includes a stirring shaft, multiple stirring rods, a drive motor, a connecting pipe, and a buffer baffle. The stirring shaft is rotatably installed at the bottom of the mixing tank. Multiple stirring rods are evenly installed on the outer wall of the stirring shaft. The input end of the stirring shaft is connected to the output end of the drive motor. A connecting pipe is connected to the lower left side wall of the mixing tank. The output end of the connecting pipe is connected to the interior of the sedimentation tank. A valve is installed inside the connecting pipe. The buffer baffle is installed on the inner wall of the mixing tank and is located below the output end of the inlet pipe. The buffer baffle buffers the incoming sewage, increasing the contact with the reagents and magnetic powder. The drive motor is started to drive the stirring shaft to rotate, which in turn drives the multiple stirring rods to rotate, mixing the reagents, magnetic powder, and sewage to improve the mixing effect and ensure the sewage treatment effect. The valve is opened to allow the mixed sewage to enter the sedimentation tank through the connecting pipe. The installation height of the mixing tank should be higher than that of the sedimentation tank, so that the sewage in the mixing tank can flow directly into the sedimentation tank without the need for pumps or other tools.

[0007] Preferably, the magnetic adsorption module includes a motor, a horizontal shaft, and multiple electromagnetic chucks. The motor is fixedly installed on the right side wall of the sedimentation tank body, and the output end of the motor is installed on the horizontal shaft. The horizontal shaft is rotatably installed inside the right side of the sedimentation tank body, and multiple electromagnetic chucks are evenly installed on the horizontal shaft. When adsorbing the flocculation formed by the combination of magnetic powder and coagulant, the electromagnetic chucks are opened to generate magnetic adsorption performance. The motor is started to drive the horizontal shaft and electromagnetic chucks to rotate. The flocculation formed by the combination of magnetic powder and coagulant is adsorbed by the electromagnetic chucks, avoiding the loss of magnetic powder and greatly improving the adsorption effect of impurities in the magnetic coagulation sedimentation tank. After the impurities are cleaned, closing the electromagnetic chucks allows the flocculation formed by the combination of magnetic powder and coagulant to fall, facilitating the recovery of magnetic powder.

[0008] Preferably, the effluent module includes two fixed plates, a sliding rod, a float plate, a water pump, a filter box, a telescopic pipe, and a mounting frame. The upper and lower ends of the sliding rod are installed on the inner left side of the sedimentation tank body via the fixed plates. The float plate is slidably installed on the outer wall of the fixed plates. The water pump is installed on the top of the float plate. The input end of the water pump is connected to the filter box, and the output end of the water pump is connected to the input end of the telescopic pipe. The output end of the telescopic pipe is installed on the top of the upper fixed plate via the mounting frame. The float plate allows the water pump to float on the water surface, and the water pump draws the upper layer of clean water. As the water level drops, the float plate slides on the sliding rod, filters impurities through the filter box, and discharges the clean water through the telescopic pipe.

[0009] Preferably, the cleaning module includes two threaded rods, two gearboxes, a dual-output motor, two drive shafts, two sliders, a U-shaped scraper, a support beam, and a drain pipe. Sliding grooves are formed on the upper inner walls of the front and rear ends of the sedimentation tank body. The threaded rods are rotatably installed in the sliding grooves. The left input end of the threaded rod is connected to the output end of the gearbox. The input end of the gearbox is connected to the front and rear output ends of the dual-output motors via the drive shafts. The dual-output motors are installed on the left side wall. The two sliders are slidably installed in the sliding grooves. The upper part of the U-shaped scraper is connected to the sliders, and the bottom of the U-shaped scraper slides in contact with the bottom of the sedimentation tank body. A support beam is connected to the top of the U-shaped scraper. A drain pipe is connected to the lower left side wall of the sedimentation tank body. After a period of time, the dual-output motors are started, driving the threaded rods to rotate via the drive shafts and gearboxes. The threaded rods drive the sliders to move within the sliding grooves, and the sliders drive the U-shaped scrapers to move inside the sedimentation tank body, pushing away impurities at the bottom. This effectively removes the sludge adhering to the conical bottom, resulting in good sludge removal. Opening the drain pipe allows the impurities to be discharged.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: In the wastewater input dosing module, chemicals and magnetic powder are added to the wastewater. The mixing module stirs and mixes the chemicals and magnetic powder, improving the mixing effect and ensuring the wastewater treatment effect. The magnetic adsorption module adsorbs the flocculation formed by the magnetic powder and coagulant, preventing the loss of magnetic powder and greatly improving the adsorption effect of impurities in the sedimentation tank. The mixed wastewater is input into the sedimentation tank, where impurities settle to the bottom. The upper clear water is discharged through the effluent module, and the cleaning module cleans the bottom of the sedimentation tank, emptying the bottom of the sedimentation tank.

[0017] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0018] Example 1

[0019] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, support legs 2 are fixedly installed at the four corners of the bottom of the sedimentation tank body 1. The bottom of the sedimentation tank body 1 is inclined towards the middle. Support base 3 is fixedly installed on the right side wall of the sedimentation tank body 1. Mixing box 4 is installed on the top of support base 3. Water inlet pipe 5 is connected to the upper part of the right side wall of mixing box 4. Dosing cylinder 6 is installed on the top of mixing box 4. A feeding hopper is provided on the top of dosing cylinder 6. The output end of dosing cylinder 6 is connected to feeding pipe 10. Feeding pipe 10 communicates with the inside of mixing box 4. Rotary shaft 7 is rotatably installed in the middle of dosing cylinder 6. The input end of rotating shaft 7 is connected to the output end of servo motor 8. Multiple dispensing plates 9 are axially installed on the outer wall of rotating shaft 7. Motor 16 is fixedly installed on the right side wall of sedimentation tank body 1. Horizontal shaft 17 is installed at the output end of motor 16. A horizontal shaft 17 is rotatably installed inside the right side of the sedimentation tank body 1. Multiple electromagnetic suction plates 18 are evenly installed on the horizontal shaft 17. Sliding grooves are opened on the upper part of the inner wall at both ends of the sedimentation tank body 1. A threaded rod 26 is rotatably installed in the sliding groove. The left input end of the threaded rod 26 is connected to the output end of the gearbox 27. The input end of the gearbox 27 is connected to the front and rear output ends of the dual output motor 28 through the transmission shaft 29. The dual output motor 28 is installed on the left side wall. Two sliders 30 are slidably installed in the sliding groove. The upper part of the U-shaped scraper 31 is connected to the slider 30. The bottom of the U-shaped scraper 31 slides in contact with the bottom of the sedimentation tank body 1. A supporting beam 32 is connected to the top of the U-shaped scraper 31. A sewage pipe 33 is connected to the lower part of the left side wall of the sedimentation tank body 1.

[0020] Wastewater enters the mixing tank 4 through the inlet pipe 5. Chemicals and magnetic powder are added to the dosing cylinder 6 through the feeding hopper. The servo motor 8, via the rotating shaft 7, drives the dispensing plate 9 to rotate, pushing the chemicals and magnetic powder evenly into the mixing tank 4 through the feeding pipe 10. This mixes the chemicals, magnetic powder, and wastewater for easy use. When adsorbing the flocculation formed by the magnetic powder and coagulant, the electromagnetic suction plate 18 is opened, generating magnetic attraction. The motor 16, driving the horizontal shaft 17 and the electromagnetic suction plate 18, causes the flocculation formed by the magnetic powder and coagulant to be attracted by the electromagnetic suction plate 18, preventing the magnetic powder from being absorbed. The loss of impurities greatly improves the adsorption effect of impurities in the magnetic coagulation sedimentation tank. After the impurities are cleaned, closing the electromagnetic suction plate 18 allows the flocculated particles formed by the magnetic powder and coagulant to fall, making it easier to recycle the magnetic powder. After a period of time, starting the dual-output motor 28 drives the threaded rod 26 to rotate through the transmission shaft 29 and the gearbox 27. The threaded rod 26 drives the slider 30 to move in the sliding groove. The slider 30 drives the U-shaped scraper 31 to move inside the sedimentation tank body 1, pushing the impurities at the bottom and scraping off the sludge attached to the conical bottom. The sludge removal effect is good. Opening the sewage pipe 33 allows the impurities to be discharged.

[0021] Example 2

[0022] like Figure 2 , Figure 3 and Figure 5As shown, based on embodiment 1, it also includes a stirring shaft 11 rotatably installed at the lower part of the mixing tank 4, a plurality of stirring rods 12 evenly installed on the outer wall of the stirring shaft 11, the input end of the stirring shaft 11 being connected to the output end of the drive motor 13, a connecting pipe 14 connected to the lower part of the left side wall of the mixing tank 4, the output end of the connecting pipe 14 being connected to the interior of the sedimentation tank body 1, a valve being installed inside the connecting pipe 14, a buffer baffle 15 being installed on the inner wall of the mixing tank 4 and located below the output end of the inlet pipe 5, the upper and lower ends of the slide rod 20 being installed on the left inner wall of the sedimentation tank body 1 through the fixing plate 19, the float plate 21 being slidably installed on the outer wall of the fixing plate 19, a water pump 22 being installed on the top of the float plate 21, the input end of the water pump 22 being connected to the filter box 23, the output end of the water pump 22 being connected to the input end of the telescopic pipe 24, and the output end of the telescopic pipe 24 being installed on the top of the upper fixing plate 19 through the mounting bracket 25;

[0023] The input sewage is buffered by the buffer baffle 15 to increase the contact with the reagents and magnetic powder. The drive motor 13 is started to drive the stirring shaft 11 to rotate. The stirring shaft 11 drives multiple stirring rods 12 to rotate to mix the reagents, magnetic powder and sewage, improve the mixing effect and ensure the sewage treatment effect. The valve is opened to allow the mixed sewage to enter the sedimentation tank body 1 through the connecting pipe 14. The installation height of the mixing box 4 should be higher than that of the sedimentation tank body 1 so that the sewage in the mixing box 4 can flow directly into the sedimentation tank body 1 without the need for tools such as water pumps. The water pump 22 can float on the water surface through the float plate 21 and pump the upper layer of clear water. As the water level drops, the float plate 21 slides on the slide rod 20 and filters impurities through the filter box 23. The clear water is discharged through the telescopic pipe 24.

[0024] like Figures 1 to 5As shown, this utility model discloses a novel modular magnetic coagulation sedimentation tank. During operation, wastewater is input into the mixing tank 4 through the inlet pipe 5. Chemicals and magnetic powder are added to the dosing cylinder 6 through the feeding hopper. The servo motor 8, via the rotating shaft 7, drives the dispensing plate 9 to rotate, pushing the chemicals and magnetic powder into the mixing tank 4 evenly through the feeding pipe 10, mixing the chemicals, magnetic powder, and wastewater. A buffer baffle 15 buffers the input wastewater, increasing contact with the chemicals and magnetic powder. The drive motor 13 drives the stirring shaft 11 to rotate, which in turn drives multiple stirring rods 12 to mix the chemicals, magnetic powder, and wastewater, ensuring effective wastewater treatment. The valve is opened to allow the mixed wastewater to enter the sedimentation tank body 1 through the connecting pipe 14. The installation height of the mixing tank 4 should be higher than the sedimentation tank body 1, so that… Wastewater in mixing tank 4 can flow directly into sedimentation tank 1 without the need for pumps or other tools. After standing for a period of time, sedimentation occurs, with the lower layer being precipitated flocculent matter and the upper layer being clear water. The water pump 22 floats on the water surface via float plate 21 and pumps the upper clear water. As the water level drops, float plate 21 slides on slide bar 20, filtering impurities through filter box 23. The clear water is then discharged through telescopic pipe 24. After a period of time, dual-output motor 28 is started, driving threaded rod 26 to rotate via drive shaft 29 and gearbox 27. Threaded rod 26 drives slider 30 to move in sliding groove. Slider 30 drives U-shaped scraper 31 to move inside sedimentation tank 1, pushing impurities at the bottom and scraping off the sludge attached to the conical bottom. The sludge removal effect is good. Opening drain pipe 33 allows impurities to be discharged.

[0025] The servo motor 8, drive motor 13, motor 16, electromagnetic chuck 18, water pump 22, gearbox 27, and dual-output motor 28 of this novel modular magnetic coagulation sedimentation tank are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
