Description

Technical Field

[0001] The present invention relates to the technical field of industrial water treatment, in particular to a disassembly-free self-cleaning filter and a use method thereof. Background Art

[0002] The filter is an indispensable device on the pipeline for conveying media. It is usually installed at the inlet end of the pressure reducing valve, pressure relief valve, constant water level valve, and other equipment of Fanggong filter. After the water to be treated passes through the filter cartridge of the filter mesh, its impurities are blocked, and the disassembly-free self-cleaning filter can automatically clean and discharge the internal impurities and sewage without disassembling the body. A large amount of water is required in the process of industrial metallurgy. Due to the huge amount of water used, a low-cost water source is usually used. The water source contains a large amount of impurities that affect metallurgy, and filters are required to perform multiple filtrations on it.

[0003] However, in the prior art, the disassembly-free self-cleaning filter still has certain deficiencies, such as the one described in Publication No. CN106731115B, "A hydraulic self-cleaning filter comprises: a shell, a filter device is provided inside the shell, both ends of the filter device are sealed with the shell, a water production chamber is formed between the outer side surface and the inner side surface of the shell, the inner cavity of the shell on the upper side of the filter device is defined as a water inlet chamber, and a drain outlet connected to the water production chamber is provided on the side wall; a turbine, the water inlet at the upper end of which is connected to the lower outlet of the shell, and the sewage outlet at the lower end is correspondingly connected to a reflux branch and a sewage branch, a reflux control valve is installed on the reflux branch, and a sewage valve is installed on the sewage branch; a rotating brush, the central axis of which is installed to rotate vertically. Inside the filter unit, the lower end of the central shaft protrudes from the underside of the filter unit and is connected to the turbine's runner. The backwash control differential pressure gauge is connected to the water inlet and water production chambers via corresponding pipelines. The water inlet pipeline is connected to the water inlet chamber of the shell and is connected to the return flow control valve via a return filter pipeline. This device uses hydraulic drive to backwash the filter, which can reduce energy consumption and maintenance costs. It also recycles wastewater, significantly reducing wastewater production. However, the filter mechanism of this device lacks internal buffering and hydraulic pressure dispersion devices. After water enters the filter mechanism, the impact force of the water flow varies across the filter. Parts of the filter that are frequently impacted by the water flow are easily damaged, shortening the service life of the device. Summary of the Invention

[0010] Furthermore, the bottom of the main tank body is fixedly connected to the tank bottom, one side of the tank bottom is fixedly connected to a drainage pipe, the middle of the tank bottom is fixedly connected to a material receiving bin, the bottom of the first filter bin is fixedly connected to the top of the material receiving bin, the bottom of the material receiving bin is fixedly connected to a discharge pipe, and a valve is fixedly installed on one side of the discharge pipe.

[0011] Furthermore, a connection port is opened on one side of the bottom of the tank bottom, a storage bin is fixedly connected to the lower surface of the tank bottom near the connection port, the bottom of the storage bin is threadedly connected to a bin bottom cover, and the bottom of the bin bottom cover is fixedly connected to a dial plate.

[0012] Furthermore, a programmable motor is fixedly installed on the top of the tank cover, a dustproof protective cover is fixedly connected to the surface of the programmable motor, the output end of the programmable motor is rotatably connected to an angular contact bearing through a load-bearing shaft, and the bottom of the angular contact bearing is rotatably connected to the top of the connecting rod.

[0013] Furthermore, a visual glass is provided on one side of the surface of the main tank body, an ultrasonic oscillator is fixedly installed on the other side of the surface of the main tank body, the top and bottom of the surface of the main tank body are fixedly connected with fixing rings, one side of the fixing rings is fixedly connected with a support frame, one side of the support frame is fixedly connected with a load-bearing plate, and one side of the load-bearing plate is threadedly connected with a fixing bolt.

[0014] The method of using the device is as follows:

[0015] S1. When the device is used, the liquid in the conversion chamber enters the first filter chamber in the main tank through the liquid inlet. Since the first filter chamber is connected to the middle of the second filter chamber, and the water injection pipe leads to one side of the conversion chamber, water flows into the conversion chamber in an inward direction, forming a vortex in the conversion chamber. The vortexed water flows into the rotating paddle, causing the rotating paddle to drive the connecting rod to rotate in the conversion chamber. The connecting rod drives the spiral stirring blade to rotate in the first filter chamber, and the edge of the spiral stirring blade contacts the inner wall of the first filter cotton.

[0016] S2. When the device is used, when the device is working and water is introduced, the water flows through the liquid port to impact the rotating plate, and the rotating plate rotates downward on one side inside the first filter chamber under the impact of the water flow, and the rotating plate rotates upward on one side outside the first filter chamber. The movable slider moves upward under the thrust of the rotating plate, and the main limit telescopic block and the auxiliary limit telescopic block are closed and compressed. When the movable slider drives the connecting contact to move upward to contact the conductive rod, electricity is transmitted to the electromagnetic coil through the connecting wire, the conductive rod, the connecting contact and the conductive plate. Since the electromagnetic coil is wound on the surface of the iron core, an electromagnet is formed between the electromagnetic coil and the iron core. At this time, the iron core generates a magnetic field. The insulating tube is sleeved on the surface of the iron core and the electromagnetic coil, and is fixed to the bottom of the tank cover. The contact part of the movable slider and the insulating tube is provided with a sealing waterproof ring, which can form a sealed space inside the insulating tube. The liquid inside the device does not enter the insulating tube. The surface of the insulating tube is smooth and wear-resistant. The insulating tube itself is not conductive, but it does not isolate the magnetic field. When the electromagnetic coil is energized, iron can be adsorbed on the surface of the insulating tube;

[0017] S3. When the device is used, the receiving bin is connected to the first filtering bin. The impurities after the first filtration can be squeezed into the receiving bin by the spiral stirring blade. When the valve is opened, the impurities in the receiving bin can be discharged to the outside of the device through the discharge pipe. The connection port is located directly below the insulating tube. When the device stops filtering water, the iron adsorbed on the surface of the insulating tube falls into the storage bin through the connection port. The bottom cover of the bin is threadedly connected to the bottom of the storage bin.

[0018] S4. When using the device, the programmable motor can drive the angular contact bearing to rotate through the load-bearing shaft, and the connecting rod is rotatably connected to the angular contact bearing, and the connecting rod can rotate unidirectionally on one side of the angular contact bearing. The programmable motor can drive the connecting rod to rotate through the angular contact bearing. When the programmable motor is not working, the connecting rod can be driven to rotate by the rotating paddle rotating under the impact of the water flow. The sound wave generating surface of the ultrasonic oscillator faces the first filter cotton and the second filter cotton, and the impurities attached to the first filter cotton and the second filter cotton that are difficult to scrape off can be vibrated off by the sound waves, which can increase the service life of the device. The fixing ring is fixed to the surface of the main tank body, and the entire device is fixed to the required fixed position through the load-bearing plate and fixing bolts.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention does not require the use of external equipment to drive the first filter chamber, the second filter chamber, the conversion chamber, the rotating paddles and the spiral stirring blades, thereby reducing energy consumption. The rotating spiral stirring blades can disperse the impact force of the water flow and evenly distribute the water flow to various places inside the first filter mesh cotton, thereby reducing the damage caused by the water flow impacting the first filter mesh cotton and improving the service life of the device. At the same time, the spiral stirring blades attached to the inner wall of the first filter mesh cotton can scrape off impurities attached to the inner surface of the first filter mesh cotton and squeeze them downward to the bottom of the first filter chamber, thereby increasing the filtration capacity of the filter mesh on the liquid and improving the working efficiency of the device.

[0021] 2. The present invention forms an electromagnet between the iron core and the electromagnetic coil through the arrangement of an insulating tube, an iron core, an electromagnetic coil, a rotating plate, a movable slider, connecting contacts, a conductive plate, a connecting wire and a conductive rod. Through the rotating plate and the movable slider, when the device passes water and filters, the electromagnet is energized and generates a magnetic field to adsorb iron. When the water passing and filtering is stopped, the electromagnet is de-energized and the magnetic field disappears. Since the device is not working, no water flow is generated inside the device, and the iron falls to the bottom of the second filter chamber, which can improve the device's filtering effect on iron, reduce energy consumption, and reduce costs.

[0022] 3. The present invention can store a large amount of impurities in the receiving bin and the storage bin during the filtration process through the arrangement of the tank bottom, the receiving bin and the storage bin, thereby increasing the storage capacity of impurities. In addition, the device does not need to stop working during the cleaning process, thereby increasing the functionality and convenience of the device.

[0023] The present invention is provided with a programmable motor, an angular contact bearing, an ultrasonic oscillator, a load-bearing plate and fixing bolts. When the device needs to be cleaned, the device can stop injecting water into the interior of the device, and the spiral stirring blade is driven to rotate by the programmable motor to stir and scrape the interior of the device. The ultrasonic oscillator is used to assist in removing impurities that are difficult to remove through sound wave impact vibration, thereby improving the functionality and convenience of the device. The entire device can be fixed to a desired fixed position through the fixing ring, the load-bearing plate and the fixing bolts, which is convenient for installation, disassembly and transportation.

[0042] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 7 and Figure 8 , a disassembly-free self-cleaning filter and its use method, including a main tank body 1, a tank cover 2 is fixedly connected to the top of the main tank body 1, a liquid outlet 3 is opened at the bottom of the tank cover 2, a first filter chamber 4 is fixedly connected to the middle of the lower surface of the tank cover 2, a first filter cotton 5 is fixedly connected to the surface of the first filter chamber 4, a second filter chamber 6 is fixedly connected to one side of the lower surface of the tank cover 2, a second filter cotton 7 is fixedly connected to the surface of the second filter chamber 6, the first filter chamber 4 is sleeved in the middle of the second filter chamber 6, the second filter chamber 6 is sleeved in the middle of the main tank body 1, a water injection pipe 8 is fixedly connected to one side of the tank cover 2, a conversion chamber 9 is fixedly connected to the middle of the conversion chamber 9, a connecting rod 10 is rotatably connected to the middle of the conversion chamber 9, a rotating paddle 11 is fixedly connected to the top of the surface of the connecting rod 10, and a spiral stirring blade 12 is fixedly connected to the bottom of the surface of the connecting rod 10;

[0043] Through the arrangement of the first filter chamber 4, the second filter chamber 6, the conversion chamber 9, the rotating paddle 11 and the spiral stirring blade 12, when the device is used, the water injection pipe 8 on one side of the tank cover 2 is connected to the external pipeline, and the liquid to be filtered is injected into the conversion chamber 9 in the middle of the tank cover 2 through the water pump in the external pipeline. A liquid through-port 3 is provided at the bottom of the tank cover 2, and the conversion chamber 9 and the first filter chamber 4 are connected through the liquid through-port 3. The liquid in the conversion chamber 9 enters the first filter chamber 4 in the main tank body 1 through the liquid through-port 3. Since the first filter chamber 4 is sleeved on the middle part of the second filter chamber 6, the main tank body 1, the first filter chamber 4 and the second filter chamber 6 are all cylindrical, and the centers of the three cylinders are on the same line, so that the liquid in the first filter chamber 4 can pass through the first filter mesh cotton 5 enters the space between the inside of the second filter chamber 6 and the outside of the first filter chamber 4. The mesh of the first filter cotton 5 is relatively coarse and the liquid is filtered for the first time. The liquid in the second filter chamber 6 can pass through the second filter cotton 7 to enter the position between the inside of the main tank 1 and the second filter chamber 6. The mesh of the second filter cotton 7 is relatively fine and the liquid is filtered for the second time. The interior of the conversion chamber 9 is cylindrical, and the water injection pipe 8 leads to one side of the interior of the conversion chamber 9. The water flow is injected into the conversion chamber 9 in an inward direction, forming a vortex in the conversion chamber 9. The water flow forming the vortex hits the rotating paddle 11, so that the rotating paddle 11 drives the connecting rod 10 to rotate in the conversion chamber 9, and the connecting rod 10 drives the spiral stirring blade 12 to rotate in the first filter chamber 4. The blade edge part of the spiral stirring blade 12 The spiral stirring blade 12 is in contact with the inner wall of the first filter cotton 5 and is driven by the water flow. Its rotation direction can squeeze the liquid to the surrounding and bottom of the first filter chamber 4, so that the pressure of the liquid on various parts of the first filter cotton 5 can be smoothly dispersed when the liquid passes through the first filter cotton 5. The liquid permeability of various parts of the first filter cotton 5 is close to the same. The edge of the spiral stirring blade 12 can squeeze the debris filtered by the inner wall of the first filter cotton 5 downward, reducing the debris attached to the surface of the first filter cotton 5. Since the general filter usually directly passes the liquid into the filter through a water pump or other device when filtering the liquid, the water pressure of the water pump is relatively strong. In the absence of a buffer structure inside the filter, the higher-pressure water flow will carry the debris directly to The inner wall of the filter screen will be damaged by long-term impact, which will destroy the integrity of the filter screen, affect the filtering effect, and reduce the service life of the device. The filter screen inside the filter will filter out particles and other debris when filtering the liquid. The filtered debris will be adhered to the surface of the filter screen by the thrust of the liquid. During the long-term use of the filter, the impurities accumulated on the surface of the filter screen will block the mesh of the filter screen, reducing the water flow rate and the filtration efficiency. The filter with buffering and stirring scraping functions is generally equipped with additional auxiliary mechanisms. Such auxiliary mechanisms are usually driven by additional motors, which increases the consumption of functions. The rotating paddle 11 and spiral stirring blades 12 provided in the device can be driven to rotate by the impact of water flow, without the need for external equipment to drive.To reduce energy consumption, the rotating spiral stirring blades 12 can disperse the impact force of the water flow and evenly distribute the water flow throughout the first filter cotton 5, reducing the damage caused by the water flow impacting the first filter cotton 5 and extending the service life of the device. At the same time, the spiral stirring blades 12 attached to the inner wall of the first filter cotton 5 can scrape off impurities attached to the inner surface of the first filter cotton 5 and squeeze them downward to the bottom of the first filter chamber 4, which can increase the filter capacity of the filter screen and improve the working efficiency of the device.

On the inner bottom wall, one side of the insulating tube 13 is slidably connected to a movable slider 22 through a limiting sliding groove opened on its surface. One side of the movable slider 22 is fixedly connected to one side of the auxiliary limiting telescopic block 20. The other side of the movable slider 22 is fixedly connected to a connecting contact 23. The interior of the movable slider 22 is fixedly connected to a sealing waterproof ring 24. The top of the surface of the iron core 14 is fixedly connected to a support plate 25. The middle part of the support plate 25 is fixedly connected to a conductive plate 26. The conductive plate 26 is fixedly connected to the top of the electromagnetic coil 15. The connecting contact 23 is slidably connected to the surface of the conductive plate 26. The inner bottom wall of the tank cover 2 is fixedly connected to a connecting wire 27. One end of the connecting wire 27 is fixedly connected to a conductive rod 28.

[0045] Through the arrangement of the insulating tube 13, the iron core 14, the electromagnetic coil 15, the rotating plate 17, the moving slider 22, the connecting contacts 23, the conductive plate 26, the connecting wires 27 and the conductive rod 28, when the device is used, there are four groups of rotating plates 17, which are respectively connected to the top of the first filter chamber 4 through four groups of spring shafts 16. When no water flows through the liquid port 3, the rotating plate 17 is in a horizontally stationary state. One side of the rotating plate 17 is inside the first filter chamber 4 and overlaps the bottom of the block 18 to form a closed state. The other side of the rotating plate 17 is outside the first filter chamber 4 and overlaps the bottom of the moving slider 22. The moving slider 22 is slidably connected to the surface of the insulating tube 13. The main limit telescopic block 19 is fixedly connected to the bottom of the tank cover 2, and the auxiliary limit telescopic block 19 is fixedly connected to the bottom of the tank cover 2. The block 20 is fixedly connected to one side of the top of the movable slider 22, and the main limit telescopic block 19 and the auxiliary limit telescopic block 20 are connected by a compression spring 21. Under the condition of no external force, the main limit telescopic block 19 and the auxiliary limit telescopic block 20 are in a stretched state due to the thrust of the compression spring 21. The connection contact 23 fixedly connected to one side of the movable slider 22 is located directly below the conductive rod 28. When the main limit telescopic block 19 and the auxiliary limit telescopic block 20 are in a stretched state due to the compression spring 21, the connection contact 23 and the conductive rod 28 are not in contact. The connection contact 23 is attached to one side of the conductive plate 26 and can slide up and down. The conductive plate 26 is fixedly connected to the electromagnetic coil 15, and the electromagnetic coil 15, the connection contact 23 and the conductive plate 26 all have good conductivity. The conductive rod 28 is fixedly connected to the connecting wire 27, and the connecting wire 27 is connected to an external power supply. When the connecting contact 23 and the conductive rod 28 are not in contact, the electromagnetic coil 15 is not energized, and the iron core 14 itself does not have a magnetic field. When the device is working and water flows in, the water flows through the liquid port 3 to impact the rotating plate 17. The rotating plate 17 rotates downward on one side inside the first filter chamber 4 under the impact of the water flow, and the rotating plate 17 rotates upward on one side outside the first filter chamber 4. The moving slider 22 moves upward under the thrust of the rotating plate 17, and the main limit telescopic block 19 and the auxiliary limit telescopic block 20 are closed and compressed. When the moving slider 22 drives the connecting contact 23 to move upward to contact the conductive rod 28, electricity is transmitted through the connecting wire 27, the conductive rod 28, the connecting contact 23 and the conductive plate 26. As for the electromagnetic coil 15, since the electromagnetic coil 15 is wound around the surface of the iron core 14, an electromagnet is formed between the electromagnetic coil 15 and the iron core 14. At this time, the iron core 14 generates a magnetic field. The insulating tube 13 is sleeved on the surface of the iron core 14 and the electromagnetic coil 15, and is fixed to the bottom of the tank cover 2. The contact portion between the movable slider 22 and the insulating tube 13 is provided with a sealing waterproof ring 24, which can form a sealed space inside the insulating tube 13, and the liquid inside the device does not enter the inside of the insulating tube 13. The surface of the insulating tube 13 is smooth and wear-resistant. The insulating tube 13 itself is not conductive, but it does not isolate the magnetic field. When the electromagnetic coil 15 is energized, iron is adsorbed on the surface of the insulating tube 13. Since the water needed for metallurgy is usually only simply filtered, and the water source itself has more iron,Moreover, a large amount of rust will be generated in the pumping device and the water pipe when used for a long time. The rust itself is not affected by the magnetic field, but a large amount of iron slag will be mixed in the process of rust generation. The water containing iron impurities will react with the metal when entering the metallurgical equipment, affecting the production effect of the product. In order to reduce the impact of iron, a metal impurity adsorption structure is generally installed in the filter. This structure is relatively complex and consumes a lot of energy. The iron slag is adsorbed by the magnet. After the device is used for a long time, the iron slag adsorbed on the surface of the magnet is difficult to clean, affecting the effect. The device can rotate the plate 17 and move the slider 22. When the device passes water and filters, the electromagnet is energized and generates a magnetic field to adsorb the iron. When the water is stopped, the electromagnet is de-energized and the magnetic field disappears. Since the device is not working, no water flow is generated inside the device, and the iron falls to the bottom of the second filter chamber 6. This can improve the device's filtering effect on iron, reduce energy consumption, and reduce costs.

When the valve 33 is opened, the impurities in the receiving bin 31 can be discharged to the outside of the device through the discharge pipe 32. The connecting port 34 is located just below the insulating tube 13. The connecting port 34 is funnel-shaped, and the small mouth faces downward and leads to the storage bin 35. When the device stops filtering water, the iron adsorbed on the surface of the insulating tube 13 falls into the storage bin 35 through the connecting port 34. The bottom cover 36 is threadedly connected to the storage bin 35. At the bottom, after the filter has been used for a long time, a large amount of impurities will remain inside, and the impurities will block the filter screen and reduce the filtration speed. In order to increase the filtration speed, the filter needs to be cleaned regularly to remove the impurities inside the filter. However, the general filter itself does not have a storage structure, and the amount of impurities that can be carried inside the device is small. In addition, the filtering work of the device needs to be stopped before cleaning, which increases the cleaning frequency and reduces the working efficiency of the device. The device can store a large amount of impurities in the receiving bin 31 and the storage bin 35 during the filtration process, which increases the storable amount of impurities. The device does not need to stop working during the cleaning process, which increases the functionality and convenience of the device.

[0050] Working principle:

[0051] 1. Through the arrangement of the first filter chamber 4, the second filter chamber 6, the conversion chamber 9, the rotating paddle 11 and the spiral stirring blade 12, the water injection pipe 8 on one side of the tank cover 2 is connected to the external pipeline, and the liquid to be filtered is injected into the conversion chamber 9 in the middle of the tank cover 2 through the water pump in the external pipeline. A liquid through-hole 3 is provided at the bottom of the tank cover 2, and the conversion chamber 9 and the first filter chamber 4 are connected through the liquid through-hole 3. The liquid in the conversion chamber 9 enters the first filter chamber 4 in the main tank body 1 through the liquid through-hole 3. Since the first filter chamber 4 is sleeved on the middle of the second filter chamber 6, the main tank body 1, the first filter chamber 4 and the second filter chamber 6 are all cylindrical, and the centers of the three cylinders are on the same line, so that the liquid in the first filter chamber 4 can pass through the first filter cotton 5 into the space between the inside of the second filter chamber 6 and the outside of the first filter chamber 4. The mesh of the first filter cotton 5 is relatively coarse, which performs the first filtration on the liquid. The liquid in the second filter chamber 6 can pass through the second filter cotton 7 into the space between the inside of the main tank body 1 and the second filter chamber 6. The position of the second filter cotton 7 is that the mesh of the second filter screen cotton 7 is finer, and the liquid is filtered for the second time. The interior of the conversion chamber 9 is cylindrical, and the water injection pipe 8 leads to one side of the interior of the conversion chamber 9. The water flow is injected into the conversion chamber 9 in an inward direction, forming a vortex in the conversion chamber 9. The water flow forming the vortex hits the rotating paddle 11, so that the rotating paddle 11 drives the connecting rotating rod 10 to rotate in the conversion chamber 9, and the connecting rotating rod 10 drives the spiral stirring blade 12 to rotate in the first filter chamber 4. The edge of the spiral stirring blade 12 contacts the inner wall of the first filter screen cotton 5. The spiral stirring blade 12 driven by the water flow can squeeze the liquid to the surrounding and bottom of the first filter chamber 4. When the liquid passes through the first filter screen cotton 5, the pressure of the liquid on various parts of the first filter screen cotton 5 can be smoothly dispersed. The liquid permeability of various parts of the first filter screen cotton 5 is close to the same. The edge of the spiral stirring blade 12 can squeeze the debris filtered by the inner wall of the first filter screen cotton 5 downward, thereby reducing the debris attached to the surface of the first filter screen cotton 5.

[0052] 2. Through the arrangement of the insulating tube 13, the iron core 14, the electromagnetic coil 15, the rotating plate 17, the movable slider 22, the connecting contact 23, the conductive plate 26, the connecting wire 27 and the conductive rod 28, when the device is used, the rotating plate 17 has four groups, which are respectively connected to the top of the first filter chamber 4 through four groups of spring shafts 16. When no water flows through the liquid port 3, the rotating plate 17 is in a horizontally stationary state. One side of the rotating plate 17 is inside the first filter chamber 4 and overlaps the bottom of the block 18 to form a closed state. The other side of the rotating plate 17 is outside the first filter chamber 4 and overlaps the bottom of the movable slider 22. The movable slider 22 is slidably connected to the surface of the insulating tube 13, and the main limit telescopic block 19 is fixedly connected to the tank. At the bottom of the cover 2, the auxiliary limit telescopic block 20 is fixedly connected to one side of the top of the moving slider 22, and the main limit telescopic block 19 and the auxiliary limit telescopic block 20 are connected by a compression spring 21. When there is no external force, the main limit telescopic block 19 and the auxiliary limit telescopic block 20 are in a stretched state due to the thrust of the compression spring 21. The connection contact 23 fixedly connected to one side of the moving slider 22 is located directly below the conductive rod 28. When the main limit telescopic block 19 and the auxiliary limit telescopic block 20 are in a stretched state due to the compression spring 21, there is no contact between the connection contact 23 and the conductive rod 28. The connection contact 23 is attached to one side of the conductive plate 26 and can slide up and down. The conductive plate 26 is fixedly connected to the electromagnetic coil 15, and the electromagnetic coil 15 and the connection contact 23 are in a stretched state. 3 and the conductive plate 26 have good conductivity, the conductive rod 28 is fixedly connected to the connecting wire 27, and the connecting wire 27 is connected to an external power supply. When the connecting contact 23 and the conductive rod 28 are not in contact, the electromagnetic coil 15 is not energized, and the iron core 14 itself does not have a magnetic field. When the device is working and water flows in, the water flows through the liquid port 3 to impact the rotating plate 17. The rotating plate 17 is impacted by the water flow on one side inside the first filter chamber 4 and rotates downward. The rotating plate 17 rotates upward on the side outside the first filter chamber 4. The moving slider 22 is pushed upward by the rotating plate 17. The main limit telescopic block 19 and the auxiliary limit telescopic block 20 are closed and compressed. When the moving slider 22 drives the connecting contact 23 to move upward to contact the conductive rod 28, the electric The force is transmitted to the electromagnetic coil 15 through the connecting wire 27, the conductive rod 28, the connecting contact 23 and the conductive plate 26. Since the electromagnetic coil 15 is wound on the surface of the iron core 14, an electromagnet is formed between the electromagnetic coil 15 and the iron core 14. At this time, the iron core 14 generates a magnetic field. The insulating tube 13 is sleeved on the surface of the iron core 14 and the electromagnetic coil 15, and is fixed to the bottom of the tank cover 2. The contact part between the movable slider 22 and the insulating tube 13 is provided with a sealing waterproof ring 24, which can form a sealed space inside the insulating tube 13, and the liquid inside the device does not enter the inside of the insulating tube 13. The surface of the insulating tube 13 is smooth and wear-resistant. The insulating tube 13 itself is not conductive, but it does not isolate the magnetic field. When the electromagnetic coil 15 is energized, iron can be adsorbed on the surface of the insulating tube 13.

[0053] 3. Through the arrangement of the tank bottom 29, the material receiving bin 31 and the material storage bin 35, when the device is used, the material receiving bin 31 is connected between the first filter bin 4, and the impurities after the first filtration can be squeezed into the material receiving bin 31 through the spiral stirring blade 12. When the valve 33 is opened, the impurities in the material receiving bin 31 can be discharged to the outside of the device through the discharge pipe 32. The connecting port 34 is located directly below the insulating tube 13. The connecting port 34 is funnel-shaped, and the small mouth is downward and passes into the material storage bin 35. When the device stops water filtration, the iron adsorbed on the surface of the insulating tube 13 falls into the material storage bin 35 through the connecting port 34. The bottom cover 36 is threadedly connected to the bottom of the storage bin 35. The bottom cover 36 can be opened to discharge the impurities in the storage bin 35.

[0054] 4. Through the arrangement of the programmable motor 38, the angular contact bearing 41, the ultrasonic oscillator 43, the load-bearing plate 46 and the fixing bolt 47, when the device is used, the programmable motor 38 can drive the angular contact bearing 41 to rotate through the load-bearing shaft 40, and the connecting rotating rod 10 is rotatably connected to the angular contact bearing 41, and the connecting rotating rod 10 can rotate unidirectionally on one side of the angular contact bearing 41. When the programmable motor 38 is working, the connecting rotating rod 10 can be driven to rotate through the angular contact bearing 41. When the programmable motor 38 is not working, the connecting rotating rod 10 can be driven to rotate by the rotating paddle 11 rotating under the impact of the water flow. The sound wave generating surface of the ultrasonic oscillator 43 faces the first filter cotton 5 and the second filter cotton 7, and the impurities that are difficult to scrape off attached to the first filter cotton 5 and the second filter cotton 7 can be vibrated off by the sound waves, thereby improving the service life of the device. The fixing ring 44 is fixed to the surface of the main tank body 1, and the entire device is fixed to the required fixed position through the load-bearing plate 46 and the fixing bolt 47.
