Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and more specifically, to a secondary water supply environmental protection device for circulating water filtration. Background Technology

[0002] Water consumption and pollution are becoming increasingly serious problems in industrial production, urban life, and agricultural activities. With the aggravation of water shortage and water pollution, wastewater treatment and reuse technologies have become key ways to solve the water crisis. Traditional wastewater treatment methods mainly focus on achieving discharge standards, while reuse technologies further transform treated wastewater into reusable water resources, realizing the recycling of water resources.

[0003] Currently, traditional circulating water filtration equipment accumulates a large amount of impurities inside the filter cartridge during prolonged operation, leading to clogging. Most existing filtration devices lack effective clogging monitoring and automatic cleaning mechanisms. During continuous filtration, impurities constantly adhere to the inner wall of the filter cartridge, not only reducing filtration efficiency and causing substandard effluent quality, but also causing excessive wear and tear on the filter cartridge over long periods, shortening its lifespan and increasing maintenance costs and replacement frequency. Furthermore, manual inspection and cleaning of the filter cartridge is not only time-consuming and labor-intensive, but also makes it difficult to detect and address clogging issues promptly, compromising the stable operation of the secondary water supply system. Therefore, we propose a secondary water supply environmental protection device for circulating water filtration. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a secondary water supply environmental protection device for circulating water filtration to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a secondary water supply environmental protection device for circulating water filtration, comprising a support frame, a water storage tank installed inside the support frame, an inlet pipe and an outlet pipe with control valves respectively installed on the top of the water storage tank, a filtration monitoring and control component installed on both the inlet and outlet pipes, a control device installed at the bottom of the support frame, a tank cover installed on the top of the water storage tank, a motor installed on the top of the tank cover, a propeller connected to the power drive end of the motor, a filter cylinder installed inside the water storage tank, a connecting frame installed on the top of the propeller, an electromagnet installed on the top of the connecting frame, a sponge pad installed between the propeller and the electromagnet, a cleaning brush installed at the bottom edge of the connecting frame, an observation window installed on the front side of the water storage tank, and a drain outlet with a control valve installed at the bottom of the water storage tank; The filtration monitoring and control component includes two sets of rotating rods connected inside the inlet and outlet pipes. Each rotating rod has a water wheel mounted on its exterior. Rubber pads are installed at the connections between the rotating rods and the inlet and outlet pipes, respectively. Gear 1 and Gear 2 are mounted on one end of each rotating rod. A guide plate and a dust cover are mounted on the outside of the water tank. A limit plate is mounted on one end of the guide plate, and a slide is connected to the outside of the guide plate. A rack is mounted on one side of the slide. Two symmetrical brackets are installed inside the dust cover. A terminal block and a metal rod are connected between the two brackets. A resistance wire is mounted on the outside of the terminal block, and a sliding plate is mounted on the outside of the metal rod. Spring 1 and Spring 2 are mounted on one side of the bottom of each bracket. Warning light 1 and Warning light 2 are mounted on one side of the outside of the dust cover.

[0006] Preferably, the propeller is located inside the filter cartridge, and the propeller is made of iron.

[0007] Preferably, the cleaning brush is located inside the filter cartridge and is used to remove impurities adhering to the inner wall of the filter cartridge.

[0008] Preferably, the observation window is a transparent window, which is used by staff to observe the water level and filtration status inside the water storage tank.

[0009] Preferably, the size of the limiting plate is larger than the size of the guide plate, and the slide block is connected to the slide piece.

[0010] Preferably, the rack has teeth at both the top and bottom, and the teeth of gear one and gear two mesh with the teeth at the top and bottom of the rack, respectively.

[0011] Preferably, one side of spring one and spring two are respectively installed on the outer sides of the slider to provide a restoring force for the slider.

[0012] Preferably, the resistor wire, the terminal block, warning light one, and warning light two form a series circuit.

[0013] Preferably, the filter cartridge is made of stainless steel, and the surface of the filter cartridge is provided with uniformly distributed filter holes for effectively filtering impurities in the circulating water.

[0014] The technical effects and advantages of this invention are as follows: 1. In use, this invention, by setting up a filter monitoring and control component, utilizes the linkage of water wheel, gear and rack at the inlet and outlet pipes, combined with a variable resistor circuit, to monitor the filter cartridge blockage in real time. When blockage occurs, an alarm light illuminates to remind the staff, and at the same time, the control device activates an electromagnet to drive a cleaning brush to automatically clean impurities from the inner wall of the filter cartridge. This blockage monitoring and automatic cleaning mechanism avoids the continuous adhesion of impurities affecting the filtration effect, prevents impurities from flying up and mixing back into the circulating water, reduces excessive wear on the filter cartridge, lowers equipment maintenance costs and replacement frequency, and eliminates the need for frequent manual inspection and cleaning, ensuring the stable operation of the secondary water supply system.

[0015] 2. When this invention is in use, the motor drives the propeller to rotate slowly, gently stirring the water in the storage tank like a stirrer. This makes the water flow more evenly distributed in the tank, allowing the circulating water to come into more full contact with the filter cartridge. This ensures that all parts of the filter cartridge can effectively filter the water, greatly improving the overall filtration efficiency and quality. Moreover, the equipment only starts cleaning when filter blockage is detected and stops after a period of cleaning. This ensures the cleanliness of the filter cartridge, maintains a good filtration condition, and avoids problems caused by long-term continuous cleaning, thus extending the service life of the equipment.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] As attached Figures 1-9 The illustrated secondary water supply environmental protection equipment for circulating water filtration includes a support frame 1. A water storage tank 2 is installed inside the support frame 1. An inlet pipe 3 and an outlet pipe 4, each equipped with a control valve, are respectively installed on the top of the water storage tank 2. A filtration monitoring and control assembly 5 is installed on both the inlet pipe 3 and the outlet pipe 4. A control device 6 is installed at the bottom of the support frame 1. A tank cover 7 is installed on the top of the water storage tank 2. A motor 8 is installed on the top of the tank cover 7. A propeller 9 is connected to the power drive end of the motor 8. The propeller 9 is located inside a filter cylinder 16 and is made of iron. The filter cylinder 16 is made of stainless steel. The surface of the filter cylinder 16 is provided with evenly distributed filter holes for effectively filtering impurities in the circulating water. A connecting frame 10 is installed on the top of the propeller 9, and an electromagnet 11 is installed on the top of the connecting frame 10. A sponge pad 12 is provided between the propeller 9 and the electromagnet 11. A cleaning brush 13 is installed at the bottom edge of the connecting frame 10. The cleaning brush 13 is located inside the filter cylinder 16 and is used to remove impurities attached to the inner wall of the filter cylinder 16. An observation window 14 is provided on the front side of the water storage tank 2. The observation window 14 is a transparent window for the staff to observe the water level and filtration status inside the water storage tank 2. A drain outlet 15 with a control valve is provided at the bottom of the water storage tank 2. The filtration monitoring and control component 5 includes two sets of rotating rods 51 connected inside the inlet pipe 3 and the outlet pipe 4. Water wheels 52 are mounted on the outside of each rotating rod 51. Rubber pads 53 are provided at the connection points of the two rotating rods 51 with the inlet pipe 3 and the outlet pipe 4, respectively. Gear 1 54 and gear 2 55 are respectively mounted on one end of each rotating rod 51. A guide plate 56 and a dust cover 510 are respectively mounted on the outside of the water storage tank 2. A limit plate 57 is mounted on one end of the guide plate 56, and the size of the limit plate 57 is larger than the size of the guide plate 56. A slide 58 is connected to the outside of the guide plate 56. A rack 59 is mounted on one side of the slide 58. Teeth are provided at the top and bottom of the rack 59. The teeth of gear 1 54 and gear 2 55 respectively engage with the teeth at the top and bottom of the rack 59. The dust cover 510 has two symmetrical brackets 511 inside, with a terminal 512 and a metal rod 513 between them. A resistance wire 514 is installed outside the terminal 512, and a slider 515 is installed outside the metal rod 513. The slide block 58 is connected to the slider 515. A spring 1 516 and a spring 2 517 are installed on one side of the bottom of the two brackets 511, respectively. One side of the spring 1 516 and the spring 2 517 are installed on the outer sides of the slider 515 to provide a return force for the slider 515. A warning light 1 518 and a warning light 2 519 are installed on the outer side of the dust cover 510. The resistance wire 514, the terminal 512, the warning light 1 518, and the warning light 2 519 form a series circuit.

[0028] The rack 59 is mounted on the slide 58, which can slide on the guide plate 56. The size of the limiting plate 57 is larger than that of the guide plate 56 to prevent the slide 58 from slipping off the guide plate 56. The slide 58 is connected to the slide piece 515, so that when the slide 58 moves, it can drive the slide piece 515 to slide on the metal rod 513. The dust cover 510 has grooves corresponding to the positions of the slide 58 and the slide piece 515. The separate operation of the cleaning brush 13 can prevent impurities that have settled or adhered to the inner wall of the filter cartridge 16 from being stirred up during continuous cleaning. These stirred-up impurities will then mix back into the circulating water, affecting the filtration effect and causing the filtered water quality to fail to meet standards. On the other hand, long-term continuous cleaning will cause excessive wear on the filter cartridge 16, shortening its service life and increasing the equipment's maintenance costs and replacement frequency. Therefore, the equipment adopts a method of starting the cleaning operation only when filter blockage is detected and stopping after a period of cleaning, which can both ensure the cleanliness of the filter cartridge 16 and avoid the above-mentioned problems. A sponge pad 12 is provided between the propeller 9 and the electromagnet 11. The sponge pad 12 is provided to prevent the rotation of the propeller 9 from damaging the electromagnet 11 when the electromagnet 11 is not energized. The sponge pad 12 plays a protective role.

[0029] Working principle of this invention: When the equipment starts working, circulating water enters the water storage tank 2 through the inlet pipe 3 equipped with a control valve. During the water flow, it impacts the water wheel 52 mounted on the rotating rod 51 inside the inlet pipe 3, causing the water wheel 52 to rotate. Since the equipment is in normal water supply and filtration is in good condition at this time, the water flow speed is relatively stable and uniform. The rotation of the water wheel 52 drives the rotating rod 51 to rotate, which in turn drives the gear 54 mounted on one end of the rotating rod 51 to rotate. At the same time, the circulating water undergoes preliminary filtration through the filter cylinder 16 inside the water storage tank 2, filtering out larger particles of impurities in the water, and then flows out from the outlet pipe 4. 4. The interior is also equipped with a rotating rod 51 and a water wheel 52; and the motor 8 installed on the top of the tank cover 7 is started. The motor 8 slowly drives the propeller 9 to rotate. In the water storage tank 2, after the water flows in from the water inlet pipe 3, due to the impact of the water and the shape of the tank, the water flow may be uneven. The propeller 9 rotates slowly, which can act like a stirrer to gently stir the water flow in the tank, so that the water flow is more evenly distributed in the water storage tank 2. This allows the circulating water to come into more full contact with the filter cartridge 16, ensuring that all parts of the filter cartridge 16 can effectively filter the water flow, thereby improving the overall filtration efficiency and quality. During normal filtration, the water flow velocity at outlet pipe 4 is only slightly different from that at inlet pipe 3. The water wheel 52 inside outlet pipe 4 drives gear 2 55 to rotate. Gear 2 55 and gear 1 54 work together on rack 59. Under normal filtration conditions, the opposing forces generated by gear 1 54 and gear 2 55 on rack 59 are in a relatively balanced state and have not reached the preset value of the rheostat. Since the opposing force has not reached the preset value of the rheostat, the slider 515 is in a specific position under the action of spring 1 516 and spring 2 517. The resistance value of the resistor wire 514 connected to the circuit has not reached the preset value for triggering the warning light. The resistor wire 514, terminal 512, warning light 1 518, and warning light 2 519 form a series circuit. Therefore, warning light 1 518 and warning light 2 519 do not light up at this time, indicating that the equipment is in normal filtration state. As the equipment runs for a long time, impurities will gradually accumulate inside the filter cartridge 16, causing it to become clogged. When the filter cartridge 16 is clogged, the water flow rate at the outlet pipe 4 will slow down because the water flow rate at the inlet pipe 3 remains basically unchanged (the control valve opening is not changed). However, the water flow rate at the outlet pipe 4 slows down, which causes the water wheel 52 inside the outlet pipe 4 to rotate at a lower speed, thereby slowing down the rotation of gear 2 55. Meanwhile, the rotation speeds of the water wheel 52 and gear 1 54 at the inlet pipe 3 remain basically unchanged. At this time, the opposing forces generated by gear 1 54 and gear 2 55 on the rack 59 are no longer balanced, and the force of gear 1 54 on the rack 59 increases relatively, causing the slide 58 to slide on the guide plate 56. This causes the slide plate 515 to move to one side, squeezing the spring 2 517. When the slide plate 515 moves to the point where the resistance value of the resistor wire 514 connected to the circuit reaches the preset value of the rheostat, the current in the series circuit changes, and the warning light 2 519 lights up, reminding the staff that the equipment is clogged. At the same time, the control device 6 receives the signal fed back by the filter monitoring and control component 5 (this signal can be obtained by detecting changes in parameters such as current and voltage in the detection circuit), and immediately starts the electromagnet 11. After the electromagnet 11 is energized, it generates magnetism, attracting the propeller 9. The propeller 9 drives the connecting frame 10 and the cleaning brush 13 to rotate during rotation. The cleaning brush 13 removes the impurities attached to the inner wall of the filter cartridge 16 through the combined action of the magnetic attraction of the electromagnet 11 and the power generated by the rotation of the propeller 9, thereby achieving the purpose of cleaning the filter cartridge 16. After the cleaning brush 13 finishes cleaning, the impurities in the filter cartridge 16 are removed, and the water flow rate at the outlet pipe 4 gradually returns to normal. At this time, the rotation speed of gear 2 55 increases, and the opposing forces of gear 1 54 and gear 2 55 on rack 59 are balanced again. The slider 515 returns to its initial position under the action of spring 1 516 and spring 2 517. The resistance value of the resistor wire 514 connected to the circuit returns to normal, the warning light 2 519 goes out, the electromagnet 11 loses its magnetism after being de-energized, and the equipment returns to normal water supply and filtration status, continuing to provide qualified circulating water to the secondary water supply system. Finally, the water filtered between the water storage tank 2 and the filter cartridge 16 can be discharged from the drain outlet 15.
