Description

Technical Field

[0001] This invention relates to the field of filter technology, specifically a fully automatic intelligent cleaning magnetic filter. Background Technology

[0002] Magnetic filters are widely used in heating systems. Magnetic filters generally contain magnetic rods and filter screens. The core function of the magnetic rods is to "actively capture iron," using strong magnetic rods to "stick" out the most harmful iron oxide particles that are invisible to the naked eye in the circulating water. The main function of the filter screen is to filter out non-magnetic impurities in the circulating water. The combination of magnetic rods and filter screens can solve three major pain points in heating systems at the same time: clogging, corrosion, and reduced efficiency.

[0003] For existing magnetic filters, as the usage time increases, the amount of iron oxide particles and non-magnetic impurities filtered out will also increase. As the usage time increases, iron oxide particles will adhere to the outside of the magnetic rod, causing the outer magnetic force to decrease. At the same time, non-magnetic impurities will adhere to the inside of the filter screen, resulting in a decrease in the permeability of circulating water and an increase in upstream pressure. Therefore, existing magnetic filters are generally assembled with a detachable connection method, and manual disassembly and cleaning are required after a predetermined period of use.

[0004] For the aforementioned manual disassembly and cleaning, firstly, it is impossible to precisely control the cleaning cycle; secondly, frequent disassembly and cleaning will reduce the comfort of use; and thirdly, the disassembly process can easily damage the sealing of the connection points, leading to water leakage after reassembly. Summary of the Invention

[0005] The purpose of this invention is to provide a fully automatic intelligent cleaning magnetic filter to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A fully automatic intelligent cleaning magnetic filter, comprising: The tank body has an electromagnetic rod and an inlet / outlet water deflector detachably installed at the bottom of the tank body, and the inlet / outlet water deflector is provided with an inlet channel and an outlet channel. A filter structure is installed inside the tank, and liquid entering the filter structure through the inlet channel can be discharged through the outlet channel after passing through the filter structure. A brushing structure is provided inside the tank, and the brushing structure is provided with bristles for removing impurities attached to the filter structure. The control component connects the water inlet and the drain pipe located at the bottom of the tank. The control structure can open the drain pipe and close the outlet when the pressure difference between the water inlet channel and the water outlet channel is greater than a preset value. A propelling component is disposed within the canister, which enables the bristle tips and middle portion to be pushed in opposite directions.

[0007] As a further aspect of the present invention: the filter structure includes an annular support member placed inside the tank, the annular support member being provided with an abutment for connecting the water inlet channel, and an annular cavity being formed between the annular support member and the inner wall of the tank, the annular cavity being connected to the water outlet channel.

[0008] As a further embodiment of the present invention: the filter structure further includes a filter screen disposed inside the annular support member, the filter screen having a notch that matches the abutment interface, and the filter screen having 300μm mesh openings.

[0009] As a further embodiment of the present invention: the brushing structure includes a cylindrical component disposed in the tank, the upper end of the cylindrical component is provided with a servo motor, and the inner and outer sides of the cylindrical component are connected. The bristles are disposed on the outside of the cylindrical component, with their ends touching the filter screen.

[0010] As a further embodiment of the present invention: the control component includes: The controller is connected to the differential pressure detection structure disposed on the inlet / outlet water diverter; The switching structure is connected to the sewage pipe and electrically connected to the controller. When the differential pressure detected by the differential pressure detection structure is greater than a preset value, the controller can control the switching structure to operate.

[0011] As a further embodiment of the present invention: the differential pressure detection structure includes a downstream pressure sensor and an upstream pressure sensor disposed on the inlet / outlet water diverter, wherein the downstream pressure sensor is used to detect the liquid pressure in the outlet water channel and the upstream pressure sensor is used to detect the pressure inside the inlet water channel.

[0012] As a further embodiment of the present invention: the switching structure includes an electric actuator installed on the side of the tank and a sealing ball head disposed in the sewage pipe. The electric actuator can drive the sealing ball head to rotate, and the sealing ball head is provided with a through hole that can communicate with the sewage pipe.

[0013] As a further embodiment of the present invention: the provocation component includes: A first drive frame and a second drive frame are offset from each other and connected by a sliding connector, and the first drive frame can slide in a guide groove provided on the cylindrical component. Multiple sets of levers are provided and respectively set on the first drive frame and the second drive frame. The two sets of levers located at the upper and lower parts of the bristles can move relative to each other. A drive structure is disposed inside the tank. The drive structure is capable of driving the first drive frame and the second drive frame to move relative to each other. When the first drive frame moves upward, the second drive frame moves downward.

[0014] As a further embodiment of the present invention: the driving structure includes a mating wheel disposed at the bottom of the first driving frame and the second driving frame, and two sets of annular connecting members disposed coaxially, wherein the mating wheel is capable of sliding inside the annular connecting members; The drive structure also includes a drive device fixedly installed on the tank body, and the drive device is connected to two sets of annular connectors.

[0015] Compared with the prior art, the beneficial effects of the present invention are: With its designed filtration structure and control components, the filter can effectively filter various impurities in liquids by working in conjunction with the electromagnetic rod and the filter screen, thereby improving the filtration efficiency. When impurities adhere to the filter screen, causing a decrease in the throughput and thus reducing the filtration efficiency, the control components can flush the electromagnetic rod and filter screen by changing the direction of the liquid flow to remove the impurities. This provides a certain degree of self-cleaning effect and ensures the stability of the filter during long-term operation without the need for manual disassembly and cleaning. The designed brushing structure and propelling component allow the bristles to directly act on the inside of the filter screen, effectively removing impurities with strong adhesion. This, combined with the fluid dynamics, enables a more thorough cleaning of the filter screen. Furthermore, the propelling component bends the bristles, gradually separating the bristle tips from the propelling rod. This process increases the distance between the bristle tips, releasing impurities hidden within the bristles, and utilizes the instantaneous rebound force of the bristles to fling out any remaining impurities. This prevents impurities from adhering to the bristles and reducing the subsequent cleaning efficiency of the filter screen. Attached Figure Description

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.

When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0028] Please see Figures 1-9 In this embodiment of the invention, a fully automatic intelligent cleaning magnetic filter includes: a tank 1, a filter structure, a brushing structure, a control component, and a stirring component.

[0029] The bottom of the tank 1 is detachably equipped with an electromagnetic rod 9 and an inlet / outlet water deflector 2. The inlet / outlet water deflector 2 is provided with an inlet water channel 201 and an outlet water channel 202. Furthermore, the tank 1 is detachably equipped with an upper cover 3. The upper cover 3 is provided with an exhaust valve 4, which can be manually opened when the system is first run or after cleaning to release the air inside the tank 1, preventing the pressure inside the tank 1 from increasing during operation and affecting the airtightness of the tank 1.

[0030] Furthermore, the aforementioned electromagnetic rod 9 is made of neodymium iron boron. It generates magnetism when the power is off and loses magnetism when the power is on. Normally, the product maintains its magnetism during operation to attract magnetic impurities and rust. When the cleaning standard is reached, the control component sends a command to connect the electromagnetic rod 9 to the power supply, and the magnetism immediately disappears. At this time, the magnetic impurities and rust can be separated from the electromagnetic rod 9 under the impact of the water flow, making the surface of the electromagnetic rod 9 cleaner, so that it can be orderly attracted to magnetic impurities and rust again. The electromagnetic rod 9 is connected to the tank 1 by a thread to facilitate repair in case of damage.

[0031] Please see Figures 4-5 The filter structure is disposed inside the tank 1. Liquid entering the filter structure through the water inlet channel 201 can be discharged through the water outlet channel 202 after passing through the filter structure. Specifically, the filter structure includes an annular support member 10 placed inside the tank 1. The annular support member 10 is provided with a contact port 1001 connecting the water inlet channel 201, and an annular cavity 1201 is formed between the annular support member 10 and the inner wall of the tank 1. The annular cavity 1201 is connected to the water outlet channel 202. The filtration structure further includes a filter screen 11 disposed inside the annular support 10. The filter screen 11 has a notch that matches the abutment interface 1001 and has 300μm mesh openings.

[0032] The annular support 10 is made of POM material, while the filter screen 11 is made of stainless steel. The two are injection molded as a whole during production, and the whole is a three-way type. The annular support 10 can support the filter screen 11 on its inner side and prevent the filter screen 11 from deforming during the filtration process.

[0033] In this embodiment, the liquid to be filtered enters the interior of the filter screen 11 through the water inlet channel 201, the contact port 1001, and the notch. Then, the liquid passes through the filter screen 11 and enters the annular cavity 1201. During this process, firstly, magnetic impurities and rust in the liquid can adhere to the surface of the electromagnetic rod 9 under the attraction of the magnetic force generated by the electromagnetic rod 9, thereby removing magnetic impurities and rust from the liquid. When the liquid passes through the filter screen 11 and enters the annular cavity 1201, non-magnetic impurities in the liquid can be filtered out and adhere to the inner side of the filter screen 11. That is, with the cooperation of the electromagnetic rod 9 and the filter screen 11, magnetic impurities, rust, and non-magnetic impurities in the liquid can be removed, improving the filtration effect.

[0034] When the liquid passes through the filter screen 11 and enters the annular cavity 1201, the liquid can be discharged through the water outlet channel 202.

[0035] Please see Figure 1 The control component is connected to the water inlet and the drain pipe 6 located at the bottom of the tank 1. The control structure can open the drain pipe 6 and close the drain pipe 202 when the pressure difference between the water inlet channel 201 and the water outlet channel 202 is greater than a preset value. The control component includes: The controller 8 is connected to the differential pressure detection structure installed on the inlet / outlet water diverter 2. The differential pressure detection structure includes a downstream pressure sensor 203 and an upstream pressure sensor 204 installed on the inlet / outlet water diverter 2. The downstream pressure sensor 203 is used to detect the liquid pressure in the outlet water channel 202, and the upstream pressure sensor 204 is used to detect the pressure inside the inlet water channel 201.

[0036] In this embodiment, as the liquid is filtered, the impurities attached to the inside of the filter screen 11 will increase. At this time, the amount of liquid entering the tank 1 through the inlet channel 201 will be greater than the amount of liquid flowing from the tank 1 to the outlet channel 202, resulting in the water pressure in the inlet channel 201 being greater than the water pressure in the outlet channel 202. At this time, the pressure detected by the upstream pressure sensor 204 will be greater than the pressure detected by the downstream pressure sensor 203. At this time, the controller 8 can control the control valve (not shown in the figure) located on the upper part of the outlet channel 202 to close the outlet channel 202. At the same time, the controller 8 controls the switching structure to open the drain pipe 6 and energize the electromagnetic rod 9 to demagnetize it. At this time, when the liquid enters the tank 1, it can flush the impurities on the inside of the filter screen 11 and the electromagnetic rod 9 and discharge them through the drain pipe 6, thereby achieving a self-cleaning effect.

[0037] Please see Figures 1-2 , Figure 4The switching structure is connected to the sewage pipe 6 and electrically connected to the controller 8. When the differential pressure detected by the differential pressure detection structure is greater than a preset value, the controller 8 can control the switching structure to operate. The switching structure includes an electric actuator 7 installed on the side of the tank 1 and a sealing ball head 701 disposed in the drain pipe 6. The electric actuator 7 can drive the sealing ball head 701 to rotate, and the sealing ball head 701 is provided with a through hole that can communicate with the drain pipe 6.

[0038] In the initial state, the through hole on the sealing ball head 701 is misaligned with the drain pipe 6, so that the drain pipe 6 is blocked. When the pressure difference between the inlet channel 201 and the outlet channel 202 is greater than the preset value, the controller 8 can control the electric actuator 7 to work, so that it can drive the sealing ball head 701 to rotate 90°. At this time, the through hole on the sealing ball head 701 can be concentric with the drain pipe 6, so that even when the outlet channel 202 is blocked, the liquid can enter the tank 1 and be discharged through the drain pipe 6, and carry away the impurities filtered out in the tank 1.

[0039] It should be noted that controller 8 integrates displays for system normal operation, flow rate, differential pressure, PLC control unit, and cleaning frequency. The power cord of electromagnetic rod 9 connects the PLC control unit to electromagnetic rod 9. The electric actuator 7 is normally closed; it can rotate 90° when energized and rotate 90° in the opposite direction when de-energized. The system is in normal operation when it is in green and in fault condition when it is red. The flow rate display shows the real-time liquid flow rate in water channel 202; The differential pressure display shows the difference between the upstream pressure sensor 204 and the downstream pressure sensor 203; The PLC control unit is a decision-making body that receives data, performs data calculations, and sends instructions. The cleaning count display shows the number of times the self-cleaning process, the demagnetization of the electromagnetic rod 9, and the opening of the drain pipe 6 have been performed.

[0040] Based on the above settings, the electromagnetic rod 9 and the filter screen 11 work together to filter various impurities in the liquid, thereby improving the filtration effect. When certain impurities adhere to the filter screen 11, causing a decrease in the throughput and thus a decrease in the filtration effect, the control component can flush the electromagnetic rod 9 and the filter screen 11 by changing the direction of the liquid flow to remove the impurities. This has a certain self-cleaning effect and ensures the stability of the filter during long-term operation.

[0041] Please see Figure 4 , Figures 6-7The brushing structure is disposed inside the tank 1. The brushing structure is provided with bristles 13 for removing impurities attached to the filter structure. The brushing structure includes a cylindrical component 12 disposed inside the tank 1. A servo motor 5 is disposed at the upper end of the cylindrical component 12, and the inner and outer sides of the cylindrical component 12 are connected. The bristles 13 are disposed on the outside of the cylindrical member 12, with their ends touching the filter screen 11, and the bristles 13 are made of highly resilient nylon material.

[0042] In this embodiment, when the pressure difference between the water inlet channel 201 and the water outlet channel 202 is greater than a preset value, the servo motor 5 will be activated, driving the cylindrical component 12 connected to its output shaft to rotate. At this time, the bristles 13 set on the outer side of the circumference of the cylindrical component 12 can act on the inner side of the filter screen 11 to wipe away some impurities with strong adhesion that cannot be removed by the liquid flow force. This action, in conjunction with the liquid flow force, can fully remove the impurities attached to the inner side of the filter screen 11, and complete the full removal of impurities under the drive of the liquid flow force.

[0043] Please see Figure 4 , Figures 6-9 The propelling component is disposed inside the tank 1, and the propelling component can push the ends and middle of the bristles 13 in opposite directions. The propelling component includes: The first drive frame 14 and the second drive frame 15 are offset from each other and connected by a sliding connector 20. The first drive frame 14 can slide in the guide groove 1202 provided on the cylindrical member 12. Multiple sets of the propelling rods 17 are provided and respectively set on the first drive frame 14 and the second drive frame 15. The two sets of propelling rods 17 located on the upper and lower parts of the bristles 13 can move relative to each other. A drive structure is provided inside the tank 1. The drive structure can drive the first drive frame 14 and the second drive frame 15 to move relative to each other. When the first drive frame 14 moves upward, the second drive frame 15 moves downward. The drive structure includes a fitting wheel 16 disposed at the bottom of the first drive frame 14 and the second drive frame 15, and two sets of annular connecting members 18 disposed coaxially. The fitting wheel 16 can slide inside the annular connecting member 18. The drive structure also includes a drive device 19 fixedly installed on the tank 1. The drive device 19 connects two sets of annular connectors 18. The drive device 19 can drive the two sets of annular connectors 18 to move relative to each other. Specifically, when the outer annular connector 18 moves downward, the aforementioned annular connector 18 will move upward, and vice versa. This allows the second drive frame 15 to move downward when the first drive frame 14 moves upward, so that the toggle lever 17 provided on the first drive frame 14 and the second drive frame 15 can move relative to each other. Furthermore, the interlocking wheel 16 can roll within the annular connector 18, so that when the cylindrical member 12 drives the bristles 13 to move, the interlocking wheel 16 can always maintain the connection with the annular connector 18, so that the action of the drive device 19 can be synchronized with the rotation of the cylindrical member 12 or performed independently.

[0044] In the application, although the liquid flow and the bristles 13 can remove impurities attached to the inside of the filter screen 11, the impurities will also be transferred to the ends of the bristles 13 during the contact process. This phenomenon is particularly obvious for some sticky impurities, which causes a certain amount of impurities to accumulate on the ends of the bristles 13, affecting the subsequent brushing of the filter screen 11.

[0045] In this embodiment, since the bristles 13 are clustered on the cylindrical member 12, by setting the lifting rods 17 on the upper and lower sides of the bristles 13, the lifting rods 17 on the upper and lower sides correspond to the middle part of the bristles 13 and the end away from the cylindrical member 12, respectively. This allows the two sets of lifting rods 17 to act on the middle and end of the bristles 13 respectively when the first drive frame 14 and the second drive frame 15 move relative to each other, causing the bristles 13 to twist. As the twisting proceeds, the ends of the bristles 13 will separate one by one from the lifting rods 17 located at the ends of the bristles 13. During this process, the bristles 13 quickly return to their original long strip state, allowing the ends of the bristles 13 to be flung outward, thereby flinging out the impurities adhering to the bristles 13.

[0046] The centrally located lever 17 increases the curvature of the bristles 13, thereby providing a greater force when the bristles 13 are reset.

[0047] Furthermore, as the bristles 13 separate from the pick-and-place lever 17 one by one, the distance between the ends of two adjacent bristles 13 can be increased, allowing impurities hidden inside the bristles 13 to be released, which to a certain extent also plays a role in removing impurities.

[0048] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0049] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
