Description

Technical Field

[0001] The invention relates to the technical field of water treatment, in particular to a high-efficiency rotary filtering device for raw water and algae. Background Art

[0002] The proliferation of algae in natural water bodies (such as lakes, rivers, and reservoirs) is primarily due to favorable temperatures, abundant sunlight, and an excessive accumulation of nutrients in the water, a phenomenon known as eutrophication. These algae reproduce rapidly, forming blooms that pose a serious threat to the quality of raw water used for drinking water and daily life. The algae themselves and their metabolites can produce unpleasant odors and odors, significantly reducing the sensory quality of the water. Some algae species can even produce algal toxins that are harmful to human health. Large algae blooms can also clog subsequent water treatment facilities, increasing treatment complexity and operating costs. The decomposition of dead algae depletes dissolved oxygen in the water, disrupting the aquatic ecosystem. Therefore, efficient algae removal before raw water enters consumption or advanced treatment processes is critical to ensuring water quality, improving the user experience, and maintaining the stable operation of treatment facilities.

[0003] Patent publication number CN218306400U discloses a pond algae removal device. The core of this device lies in the design of its filtering mechanism: raw water enters through the inlet pipe, where algae are effectively intercepted and collected above the third filter screen. The filtered water is then discharged through the outlet pipe. When the collected algae needs to be cleaned, the electric telescopic rod is activated, driving the first filter screen to push the second and third filters toward the cleaning mechanism. The cleaning mechanism then discharges the algae accumulated on the third filter screen into the treatment tank. However, when this device uses the cleaning mechanism to discharge the collected algae from the tank, the large amount of water entrained in the algae cannot be effectively separated and recovered. This water is discharged along with the algae as waste, resulting in a direct waste of precious water resources. This problem is particularly prominent in drought-stricken or water-scarce areas. Furthermore, the high water content of the algae residue increases the difficulty and cost of subsequent transportation and disposal.

[0004] Based on this, a high-efficiency rotary filtration device for raw water and algae is now provided, which can eliminate the disadvantages of existing devices. Summary of the Invention

The upper end of the filter cartridge 11 is provided with a liquid inlet, and a baffle 26 is hingedly provided at the liquid inlet. Several support wheels 16 are tightly provided on the inner side of the transmission belt 12, and the support wheels 16 are rotatably provided on the mounting frame 13. A liquid storage tank 18 is fixedly provided at the bottom end of the mounting frame 13, a partition cover 19 is fixedly provided in the middle of the liquid storage tank 18, and a drain pipe 58 is connected to the bottom end of the liquid storage tank 18. The mounting frame 13 and the liquid storage tank 18 are fixedly provided on the mounting box 20. Inside, a raw water tank 22 is fixedly provided at a position corresponding to the middle position of the transmission belt 12 inside the installation box 20, and a water inlet pipe 21 is provided inside the raw water tank 22, and the water inlet pipe 21 extends to the outside of the installation box 20. A switching mechanism is provided below the raw water tank 22 for facilitating the switching control of a plurality of filter cartridges 11, and a dehydration mechanism is provided above the raw water tank 22 for facilitating the collection and dehydration of algae. The switching mechanism can prevent the raw water inside the raw water tank 22 from flowing out when the filter cartridges 11 are switched, and at the same time, when the filter cartridges 11 move to the bottom of the raw water tank 22, the baffle 26 is automatically opened, and the dehydration mechanism facilitates the collection and transportation of the algae inside the filter cartridges 11, and the algae can be dehydrated during the transportation process; Both ends of the outer side of the transmission belt 12 are fixed with a first friction belt 14, and the outer side of the transmission belt 12 corresponding to the position of the support wheel 16 is matched with an active friction wheel 15, and the active friction wheels 15 are tightly attached to the first friction belt 14, and a transmission shaft is fixed between the coaxial active friction wheels 15. The rotating shafts at one end of the active friction wheels 15 are rotatably arranged on the mounting frame 13, and a first synchronous gear is fixed on the rotating shaft at one end of the active friction wheels 15. The first synchronous gear is connected to the second synchronous gear through a synchronous toothed belt, and the second synchronous gear is fixed to the output end of the first motor 17. The first motor 17 is fixed on the mounting frame 13, and the first motor 17 is electrically connected to the control component 59. Component 59 is fixed on one side of the installation box 20. During use, when the raw water needs to be filtered, the water inlet pipe 21 is connected to the output end of the external liquid supply component, so that the external liquid supply component transports the raw water to be filtered to the inside of the raw water tank 22. At the same time, the control component 59 controls the first motor 17 to drive the active friction wheel 15 to rotate. The active friction wheel 15 cooperates with the first friction belt 14 to drive the transmission belt 12 to rotate. The transmission belt 12 drives several filter cartridges 11 to rotate intermittently. At the same time, a filter cartridge 11 moves to the bottom of the raw water tank 22 and stops. Then the raw water flows into the filter cartridge 11. The filter cartridge 11 can filter the raw water through the filter holes. The algae are intercepted inside the filter cartridge 11. The raw water flows to the inside of the liquid storage tank 18 through the circular perforations on the transmission belt 12.

[0032] The switching mechanism includes a steering gear 25 and an infrared sensor 33. A fixed rod 27 is fixed on the rotating shaft at both ends of the baffle 26. A toggle block 28 is fixed at one end of the fixed rod 27. A first guide plate 30 is symmetrically provided inside the installation box 20 and below the raw water tank 22. One end of the first guide plate 30 is tilted, and the bottom end of the first guide plate 30 is in close contact with the toggle block 28. The other end of the toggle block 28 is fixed with a fixed disk. A fixed tube is rotatably provided on the outer side of the fixed disk. The fixed tubes are fixed on the filter cartridge 11. A torsion spring 29 is provided between one end of the fixed tube and one side of the fixed disk. The filter cartridge 11 is symmetrically provided with a first support frame 31, and one end of the first support frame 31 is symmetrically provided with a limiting wheel, and the limiting wheel is tightly attached to the limiting frame 32, and the limiting frame 32 is fixed on both sides of the mounting frame 13. The bottom end of the raw water tank 22 is connected with a valve pipe 23, and the valve pipe 23 is symmetrically provided with a first support plate, and the other end of the first support plate is fixed inside the mounting box 20. A valve core 24 is rotatably provided inside the valve pipe 23, and one end of the valve core 24 is fixed with a linkage frame, and the other end of the linkage frame is fixedly connected to the output end of the steering gear 25. The steering gear 25 is fixed on the first support plate, and the steering gear 25 is connected to the control Component 59 is electrically connected, and an infrared sensor 33 is symmetrically provided on the mounting frame 13 and directly below the raw water tank 22. The infrared sensor 33 is electrically connected to the control component 59. When in use, when the transmission belt 12 drives a filter cartridge 11 to move to the bottom of the raw water tank 22, the toggle block 28 first clings to the inclined end of the first guide plate 30, and the first guide plate 30 guides the toggle block 28. As the transmission belt 12 continues to rotate, the toggle block 28 drives the baffle 26 to rotate through the fixed rod 27, the liquid inlet is in an open state, the filter cartridge 11 moves to the bottom of the raw water tank 22, and the liquid inlet is aligned with the liquid outlet end of the valve tube 23. When the fixed plate is between the two infrared sensors 33, the fixed plate blocks the infrared rays, so that the infrared rays emitted by one infrared sensor 33 are blocked and cannot be received by the other infrared sensor 33. The control component 59 controls the servo 25 to start, and the servo 25 drives the valve core 24 to rotate 90 degrees, so that the raw water inside the raw water tank 22 is discharged into the filter cartridge 11 for filtration. After the filter cartridge 11 stays for a fixed time, the transmission belt 12 drives the filter cartridge 11 to move again. When the fixed plate does not block the infrared rays, the output end of the servo 25 drives the valve core 24 to rotate 90 degrees again, thereby closing the liquid outlet end of the raw water tank 22.

[0033] The dehydration mechanism includes a transmission pipe 40, which is fixedly arranged inside the return pipe 43. The return pipe 43 is arranged in a frustum shape.

The output end is fixedly connected, the third motor 42 is fixedly installed at one end of the return pipe 43, the return pipe 43 is connected with a first delivery pipe, one end of the first delivery pipe extends to the inside of the raw water tank 22, the installation box 20 is symmetrically provided with a second guide plate 34 above the collecting cover 39, one end of the second guide plate 34 is inclined, and the upper end of the second guide plate 34 is in close contact with the toggle block 28. When in use, when the transmission belt 12 drives the filter cartridge 11 to leave the bottom of the raw water tank 22, the toggle block 28 Separated from the first guide plate 30, under the action of the torsion spring 29, the baffle 26 closes the liquid inlet, and then the transmission belt 12 drives the filter cartridge 11 to move to the top of the collection cover 39. The toggle block 28 first clings to the inclined end of the second guide plate 34, so that the second guide plate 34 guides the toggle block 28, causing the baffle 26 to rotate and the liquid inlet end of the filter cartridge 11 to open. At this time, the filter cartridge 11 is in an inverted state, so that under the action of gravity, the algae inside the filter cartridge 11 falls into the collection cover 39. The algae then enters the transmission pipe 40, the third motor 42 drives the installation shaft to rotate, and the installation shaft drives the spiral plate 41 to rotate. The spiral plate 41 cooperates with the transmission pipe 40 to transport the algae, and because the pitch of the spiral plate 41 is gradually reduced, the spiral plate 41 can squeeze and dehydrate the algae during the transportation process, and the squeezed raw water is discharged into the return pipe 43 through several drainage holes on the transmission pipe 40. The return pipe 43 re-transports the raw water to the raw water tank 22 through the first delivery pipe.

[0034] The fixed shaft is provided with a stirring plate 38 at one end, and the other end of the fixed shaft is fixedly provided with a driven friction wheel 35.

The second motor 37 is electrically connected with the control component 59. When the filter cartridge 11 moves above the material collecting cover 39, the driven friction wheel 35 is in close contact with the bottom end of the second friction belt 36. At the same time, the second motor 37 drives the second friction belt 36 to rotate, so that the second friction belt 36 drives the fixed shaft to rotate through the driven friction wheel 35. The fixed shaft drives the stirring plate 38 to rotate. The stirring plate 38 is in close contact with the inside of the filter cartridge 11, so that the waterweed in the filter cartridge 11 can be easily discharged.

[0035] The material collecting cover 39 is provided with a cleaning pipe 44 above. The cleaning pipe 44 is arranged outside the transmission belt 12. The cleaning pipe 44 is fixedly arranged inside the mounting frame 13. The bottom end of the cleaning pipe 44 is provided with a plurality of spray holes. The input end of the cleaning pipe 44 is in communication with a second conveying pipe. The other end of the second conveying pipe is in communication with the output end of a first pump body 45. The first pump body 45 is fixedly arranged on the mounting frame 13. The liquid storage tank 18 and the partition cover 19 are combined into a water storage tank. The input end of the first pump body 45 is in communication with the inside of the water storage tank. When the filter cartridge 11 moves above the material collecting cover 39 and stops, the input end of the first pump body 45 extracts the filtered raw water in the water storage tank. Then the raw water is conveyed to the inside of the cleaning pipe 44. The cleaning pipe 44 sprays the raw water, so that the filter cartridge 11 can be backflushed, and the waterweed in the filter cartridge 11 can be discharged. Example 2

[0036] The difference from example 1 is that the bottom end of the partition cover 19 is in communication with a butt joint pipe.

A rotating roller 47 is rotatably arranged in the inside of the mounting cylinder 46. A plurality of transfer grooves are arranged in the inside of the rotating roller 47. Stirring rods 49 are rotatably arranged in the transfer grooves. A mounting pipe 53 is in communication with the inside of the mounting cylinder 46. The mounting pipe 53 is in communication with the output end of a second pump body 56. The second pump body 56 is fixedly arranged inside the bottom end of the liquid storage tank 18. The input end of the second pump body 56 is in communication with the inside of a medicine box 57. The medicine box 57 is fixedly arranged on one side of the mounting box 20.

The rotating shaft at the other end of the rotating roller 47 is rotatably arranged on the second support frame. The second support frame is fixed on the mounting cylinder 46. When in use, when the filtered raw water needs to add medicine, the fourth The motor 48 and the fourth motor 48 drive the rotating roller 47 to rotate. When a transfer trough on the rotating roller 47 is aligned with one end of the docking pipe, the raw water inside the liquid storage tank enters the transfer trough. When the outer side of the rotating roller 47 is in close contact with the docking pipe, one end of the docking pipe is closed, and the interior of the transfer trough is not completely filled with raw water. Then, when the transfer trough moves to one end of the mounting tube 53, the second pump body 56 extracts the liquid medicine inside the medicine box 57 and transports it to the interior of the transfer trough. Then, during the rotation of the rotating roller 47, the fifth motor 52 drives the driving gear ring 51 to rotate.

During use, when the second pump body 56 delivers liquid medicine to the inside of the mounting cylinder 46, the liquid medicine pushes the sealing block 54 to slide, so that the liquid medicine enters the transfer tank. When the second pump body 56 stops delivering, under the action of the return spring 55, the return spring 55 closes one end of the mounting tube 53, thereby preventing the liquid medicine and raw water from flowing back.

[0039] The above embodiment discloses a high-efficiency rotary filtration device for raw water and algae, wherein when the raw water needs to be filtered, the water inlet pipe 21 is connected to the output end of the external liquid supply component, so that the external liquid supply component transports the raw water to be filtered into the raw water tank 22, and at the same time, the control component 59 controls the first motor 17 to drive the active friction wheel 15 to rotate, and the active friction wheel 15 cooperates with the first friction belt 14 to drive the transmission belt 12 to rotate, and the transmission belt 12 drives several filter cartridges 11 to rotate intermittently. In the process of the transmission belt 12 driving a filter cartridge 11 to move to the bottom of the raw water tank 22, the toggle block 28 first clings to the inclined end of the first guide plate 30, and the first guide plate 30 guides the toggle block 28. As the transmission belt 12 drives a filter cartridge 11 to move to the bottom of the raw water tank 22, the toggle block 28 first clings to the inclined end of the first guide plate 30, and the first guide plate 30 guides the toggle block 28. The driving belt 12 continues to rotate, causing the toggle block 28 to rotate the baffle 26 via the fixed rod 27. The liquid inlet is in the open state, and the filter cartridge 11 moves to the position directly below the raw water tank 22. When the liquid inlet is aligned with the liquid outlet end of the valve tube 23, the fixed plate is located between the two infrared sensors 33, blocking the infrared rays emitted by one infrared sensor 33 and preventing them from being received by the other infrared sensor 33. The control component 59 controls the steering gear 25 to start, and the steering gear 25 drives the valve core 24 to rotate 90 degrees, so that the raw water in the raw water tank 22 is discharged into the filter cartridge 11 for filtration. The algae are intercepted in the filter cartridge 11, and the raw water flows into the water storage tank through the circular perforations on the driving belt 12. After the filter cartridge 11 has stayed for a fixed time, the transmission belt 12 drives the filter cartridge 11 to move again. When the fixed plate does not block the infrared light, the output end of the servo 25 drives the valve core 24 to rotate 90 degrees again, thereby closing the liquid outlet end of the raw water tank 22. At the same time, the toggle block 28 is separated from the first guide plate 30. Under the action of the torsion spring 29, the baffle 26 closes the liquid inlet. Subsequently, when the transmission belt 12 drives the filter cartridge 11 to move above the collecting cover 39, the toggle block 28 first clings to the inclined end of the second guide plate 34, so that the second guide plate 34 guides the toggle block 28, causing the baffle 26 to rotate, and the liquid inlet end of the filter cartridge 11 is closed. When the filter cartridge 11 is opened, it is in an upside-down state, so that under the action of gravity, the algae inside the filter cartridge 11 falls into the collecting cover 39. At the same time, the driven friction wheel 35 is in close contact with the bottom end of the second friction belt 36. The second motor 37 drives the second friction belt 36 to rotate, so that the second friction belt 36 drives the fixed shaft to rotate through the driven friction wheel 35, and the fixed shaft drives the material-diverting plate 38 to rotate to dig the algae out. At the same time, the input end of the first pump body 45 draws the filtered raw water from the water storage tank, and then transports the raw water to the inside of the cleaning pipe 44. The cleaning pipe 44 sprays the raw water out, thereby backflushing the filter cartridge 11 and further discharging the algae inside the filter cartridge 11. Subsequently, the algae enter the inside of the transmission pipe 40, the third motor 42 drives the installation shaft to rotate, the installation shaft drives the spiral plate 41 to rotate, the spiral plate 41 cooperates with the transmission pipe 40 to transport the algae, and because the spiral pitch of the spiral plate 41 is gradually reduced, the spiral plate 41 can extrude and dehydrate the algae during the transportation process, the extruded raw water is discharged into the reflux pipe 43 through the drainage holes on the transmission pipe 40, and the reflux pipe 43 re-transport the raw water into the raw water tank 22 through the first conveying pipe.

[0040] When the filtered raw water needs to add reagents, the fourth motor 48 is started, the fourth motor 48 drives the rotating roller 47 to rotate, when the one transfer groove on the rotating roller 47 is aligned with one end of the butt joint pipe, the raw water in the liquid storage groove enters the transfer groove, when the outer side of the rotating roller 47 is close to the butt joint pipe, the one end of the butt joint pipe is closed, and the transfer groove is not completely filled with raw water, then when the transfer groove moves to one end of the installation pipe 53, the second pump body 56 extracts the liquid medicine in the medicine box 57 and transports it to the inside of the transfer groove, then during the rotation of the rotating roller 47, the fifth motor 52 drives the driving gear ring 51 to rotate, the driving gear ring 51 is engaged with the plurality of driven gears 50, so that the stirring rod 49 rotates during the revolution, so that the raw water and the liquid medicine are mixed, then when the transfer groove rotates to the position of the liquid outlet of the installation cylinder 46, the raw water in the transfer groove is discharged to the bottom end of the liquid storage tank 18, then the raw water is discharged outside through the drain pipe 58.

[0041] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
