Description

Technical Field

[0001] This invention relates to the field of water treatment, and more specifically to a magnetic resin water purification device. Background Technology

[0002] Magnetic resin water purification technology is a rapidly developing water treatment method in recent years. It utilizes magnetic ion exchange resin particles to efficiently remove dissolved pollutants from water, such as nitrates, phosphates, and heavy metal ions. Compared to traditional fixed-bed or fluidized-bed ion exchange equipment, magnetic resins have excellent dispersibility and recyclability, facilitating separation and recovery via magnetic fields. Therefore, they have broad application prospects in areas such as advanced drinking water treatment and industrial wastewater reuse.

[0003] However, in actual use, magnetic resin particles will gradually break down due to mechanical collisions, hydraulic shearing, and other factors, producing small broken particles. These broken particles not only lose some of their ion exchange capacity but may also clog the filter screen and mix into the effluent, affecting the quality of the effluent. At the same time, existing equipment lacks an online identification, isolation, and discharge mechanism for broken particles, which usually requires shutdown to replace or clean the filter element, affecting the continuous operating efficiency and service life of the equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a magnetic resin water purification device to solve at least one of the above-mentioned technical problems.

[0005] The objective of this invention can be achieved through the following technical solutions: A magnetic resin water purification device includes a first treatment tank and a second treatment tank. The outlet of the first treatment tank is connected to the inlet of the second treatment tank via a water supply pipe. An activated carbon adsorption layer is provided inside the first treatment tank, and a magnetic resin filter element and a magnetic adsorption mechanism are provided inside the second treatment tank. A dividing mechanism is also provided inside the second treatment tank. The dividing mechanism is used to cooperate with the magnetic adsorption mechanism to divide the interior of the magnetic resin filter element into two independent chambers to discharge broken magnetic resin particles. The magnetic resin filter element is provided with two sets of outlets corresponding to each chamber, and the output end of each outlet is connected to the two outlets of the second treatment tank respectively.

[0006] Furthermore, the magnetic adsorption mechanism includes a magnetic roller, the surface of which has a magnetic field area capable of adsorbing magnetic resin particles, and a semi-annular permanent magnet fixedly arranged inside the magnetic roller, the permanent magnet covering a circumferential range of 120° to 270° of the magnetic roller. The magnetic roller is located on one side of the magnetic resin filter element, and a rotating shaft is fixedly installed at the center of the top of the magnetic roller. The top of the rotating shaft extends upward to the top of the second processing box and is connected to the drive motor. The drive motor is fixedly installed on the top of the second processing box.

[0007] Furthermore, the dividing mechanism includes dividing plates and opening slots. The opening slots are opened on the upper and lower side walls of the magnetic resin filter element, and the dividing plates are slidably and sealed in the opening slots. The dividing plates are configured in a T-shape, and one end of the dividing plates in the T-shape is hinged to a connecting rod. A limit slide rail is vertically provided on the inner side wall of the second processing box. The ends of the two connecting rods are fixedly provided with sliders, and the two sliders are slidably and limited inside the limit slide rail. An adjustable spacing component is provided between the two connecting rods. The adjustable spacing component is used to adjust the distance between the two connecting rods so that the other end of the corresponding dividing plate contacts and closes inside the magnetic resin filter element, dividing the inside of the magnetic resin filter element into two opposing chambers.

[0008] Furthermore, the adjustable pitch component includes a first gear, a second gear, and a gear ring. The gear ring is rotatably mounted on the top of the second processing box, and the first gear and the second gear are respectively located on both sides of the top of the second processing box and are both meshed with the gear ring for transmission. The first gear is fixedly sleeved on the rotating shaft, and the second gear is rotatably connected to the top of the second processing box. The gear shaft fixed at the center of the second gear extends downward into the interior of the second processing box. A lead screw is fixedly installed at the bottom end of the gear shaft, and collars are sleeved at both ends of the lead screw. The collars are fixedly installed on the inner side wall of the second processing box. The lead screw is provided with two sections of threads with opposite directions. Two nuts are sleeved on the lead screw, and each nut is screwed into the corresponding thread section. The two nuts are respectively fixedly installed on the middle of the corresponding connecting rod.

[0009] Furthermore, a flexible buffer pad is provided at one end of the dividing plate for mutual contact and closure. The flexible buffer pad is made of an elastomer material, and multiple particle-filling pits are formed on the surface of the flexible buffer pad. When the two partition plates approach and close to each other under the drive of the adjustable spacing component, the flexible buffer pad contacts the rigid end face of the partition plate first and is compressed in the fully closed state, while a gap is maintained between the rigid end faces of the two partition plates.

[0010] Furthermore, the magnetic resin filter element is equipped with corresponding filter screens at both the inlet and two outlets. One of the outlet filter screens is equipped with a linkage mechanism, which is used to open the filter screen after two independent chambers are formed inside the magnetic resin filter element.

[0011] Furthermore, the linkage mechanism includes a pull rope and a secondary baffle. The secondary baffle is rotatably connected to the side of the lower dividing plate away from the swing plate via a first torsion spring, and the free end of the secondary baffle is set in an arc shape. A slot is opened on the end face of the lower dividing plate. One end of the pull rope passes through the slot and is fixed to the arc shape of the secondary baffle. The other end of the pull rope is fixedly connected to the free end of the swing plate. An embedding groove is opened on the inner bottom wall of the magnetic resin filter element. One end of the embedding groove is rotatably connected to the swing plate via a second torsion spring. The filter screen is embedded and fixed in the middle of the swing plate. The torque of the second torsion spring is less than that of the first torsion spring. When the lower dividing plate moves upward, the pull rope is pulled, and the secondary baffle rotates around its hinge point under the pressure of the pull rope and presses the pull rope. At the same time, the pull rope pulls the swing plate to rotate upward, causing the filter screen on the swing plate to leave the corresponding outlet.

[0012] Furthermore, the arc-shaped structure of the sub-baffle is configured as an arc-shaped sealing cover that matches the joint between the two partition plates; when the two partition plates approach each other and are squeezed and sealed under the drive of the adjustable spacing component, the arc-shaped structure covers the joint between the two partition plates, forming a sealing cover on the joint.

[0013] The beneficial effects of this invention are: This invention incorporates both a magnetic adsorption mechanism and a segmentation mechanism within the second processing chamber. The magnetic roller in the magnetic adsorption mechanism generates a directional magnetic field through an internal semi-annular permanent magnet, actively adsorbing resin particles whose magnetism has weakened after breakage, thus achieving online identification and enrichment of damaged particles. Furthermore, the segmentation mechanism works in conjunction with the magnetic adsorption mechanism. Once damaged particles are adsorbed to a designated area, the segmentation mechanism divides the interior of the magnetic resin filter element into two independent chambers. One chamber concentrates the damaged particles, while the other retains intact particles. Since each chamber has an independent outlet, the equipment can separately export the material from the chamber containing damaged particles without interrupting the overall water purification process, while the other chamber continues normal filtration. This solves the problem of traditional equipment requiring shutdown for filter replacement or cleaning, while also reducing the probability of damaged particles entering the outlet pipe, thereby improving the water purification effect and the equipment's continuous operation capability.

[0017] 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.

[0018] Please see Figures 1-3 As shown, the present invention provides a magnetic resin water purification device; Example 1:

[0019] The overall structure includes a first treatment tank 1 and a second treatment tank 2. The outlet 7 of the first treatment tank 1 is connected to the inlet of the second treatment tank 2 via a water supply pipe 3, forming a two-stage series treatment process. The first treatment tank 1 is equipped with an activated carbon adsorption layer, which is used to remove residual chlorine, organic matter, colloids, and some heavy metal ions from the raw water, serving as a pretreatment and protecting the subsequent magnetic resin filter element 4. The second treatment tank 2 is equipped with a magnetic resin filter element 4, which is filled with magnetic resin particles. These particles are magnetic and have ion exchange groups on their surface, enabling them to efficiently adsorb dissolved pollutants in the water, such as nitrates, phosphates, and heavy metal ions.

[0020] The second processing chamber 2 is also equipped with a magnetic adsorption mechanism 5, which can actively adsorb damaged magnetic resin particles. Because the magnetism of damaged particles may be weakened or their shape may be changed, they can still be attracted by the magnetic field. More importantly, the second processing chamber 2 is equipped with a dividing mechanism 6. The dividing mechanism 6 works in conjunction with the magnetic adsorption mechanism 5. Its core function is to divide the inside of the magnetic resin filter element 4 into two independent chambers. When the magnetic adsorption mechanism 5 detects or collects damaged particles, the dividing mechanism 6 is activated to divide the filter element into two non-connected areas. One area contains the damaged particles, while the other area retains the intact particles.

[0021] Subsequently, by controlling the outlet 7 corresponding to each chamber, the material in the chamber containing broken particles can be discharged, while intact particles continue to be used for filtration. The magnetic resin filter element 4 is equipped with two sets of outlets 7, each set corresponding to one chamber. The output end of each outlet 7 is connected to the two outlets 7 of the second treatment box 2, so that water containing broken particles or normal water can be discharged as needed.

[0022] This solution addresses the problem in traditional water purification equipment where broken particles cannot be detected in time and can mix into the effluent, reducing water quality. On one hand, the magnetic adsorption mechanism 5 actively identifies and enriches intact particles, solving the issue of broken particles not being detected in time and thus contaminating the effluent and lowering water quality. This achieves online separation of broken particles. On the other hand, the dividing mechanism 6 quickly physically divides the filter cartridge into two independent chambers after adsorption. One chamber concentrates broken particles, while the other retains intact particles, reducing the chance of accidentally discharging intact particles along with broken particles during the removal process. Furthermore, two independent outlets 7 correspond to the two chambers, allowing the equipment to selectively discharge water containing broken particles or normal effluent as needed, enabling maintenance without shutting down the system. That is, while removing broken particles, the other chamber can still filter normally, ensuring continuous operation of the water purification equipment. This solution organically combines activated carbon pretreatment with deep treatment of the magnetic resin. The activated carbon layer first removes large molecular organic matter and residual chlorine, preventing the magnetic resin from being contaminated or oxidized, thereby further extending the effective working cycle of the magnetic resin.

[0023] As one embodiment, the specific structure of the magnetic adsorption mechanism 5 is further defined. The magnetic adsorption mechanism 5 includes a magnetic roller 51. The surface of the magnetic roller 51 has a magnetic field region capable of adsorbing magnetic resin particles. This means that the outer surface of the roller can generate magnetic force within a specific angular range, adsorbing nearby suspended or accumulated magnetic resin particles onto the roller surface. To achieve this non-full-circumferential magnetic field distribution, a semi-annular permanent magnet 52 is fixedly installed inside the magnetic roller 51. This permanent magnet 52 covers a circumferential range of 120° to 270° of the magnetic roller 51, preferably 180° or 240°. This ensures that when the magnetic roller 51 rotates, only a portion of the circumferential area has magnetic adsorption capacity, while the remaining area is non-magnetic. This facilitates selective adsorption of magnetic resin particles inside the magnetic resin filter element 4. The magnetic roller 51 is located on one side of the magnetic resin filter element 4, specifically on the side of the filter element, to facilitate the adsorption of magnetic resin particles with complete magnetic force from inside the filter element.

[0024] A rotating shaft 53 is fixedly installed at the top center of the magnetic roller 51. The top end of the rotating shaft 53 extends upward to the top of the second processing box 2 and is connected to the drive motor 54. The drive motor 54 is fixedly installed at the top of the second processing box 2. When the drive motor 54 drives the rotating shaft 53 to rotate, the non-magnetic area of ​​the magnetic roller 51 is opposite to the filter element in the initial state. After the magnetic roller 51 rotates, the magnetic field area on its surface begins to face the filter element area, thereby adsorbing the complete magnetic resin particles with strong magnetism into the cavity opposite to the magnetic roller 51.

[0025] In this design, a semi-annular permanent magnet 52 is used instead of a full-circumference magnet, so that only part of the circumference of the magnetic roller 51 has adsorption capacity when it rotates, while the rest is non-magnetic, thereby achieving an effective cycle of adsorption and release. The magnetic roller 51 is located on one side of the filter element, rather than being immersed in the filter element, which avoids the violent disturbance of the particle layer inside the filter element caused by the rotation of the roller and prevents intact particles from being accidentally damaged by impact.

[0026] As one embodiment, the dividing mechanism 6 includes a dividing plate 61 and an opening groove 62. The opening groove 62 is formed on the upper and lower side walls of the magnetic resin filter element 4, and the dividing plate 61 is slidably and sealed within the opening groove 62. Therefore, there is an opening on the upper and lower walls of the filter element. The dividing plate 61 is inserted into the filter element from the outside through the opening, and water is prevented from leaking from the opening by a sealing element, such as a rubber sealing ring or a labyrinth seal. The dividing plate 61 is configured as a T-shaped structure. The horizontal part of the T is located outside the filter element and is used to connect the connecting rod 63, while the vertical part extends into the filter element as a separator.

[0027] Each of the T-shaped partition plates 61 has one end of a connecting rod 63 fixed to it, and the upper and lower partition plates 61 are respectively fixed to their respective connecting rods 63. A limit slide rail 64 is vertically provided on the inner wall of the second processing box 2. A slider 65 is fixedly provided at the end of each of the two connecting rods 63. The two sliders 65 are slidably installed inside the limit slide rail 64, so the end sliders 65 of the two connecting rods 63 are both installed on the same vertical slide rail, which can slide up and down but cannot move left and right. An adjustable spacing component 66 is provided between the two connecting rods 63, which is used to adjust the distance between the two connecting rods 63. Since the end sliders 65 of the two connecting rods 63 are on the same slide rail, when the distance between the connecting rods 63 changes, the two partition plates 61 are driven to move towards each other or away from each other.

[0028] Specifically, when the adjustable spacing component 66 reduces the distance between the two connecting rods 63, the two dividing plates 61 move closer to each other, eventually contacting and closing inside the filter element, dividing the filter element into two opposing chambers; when the distance increases, the dividing plates 61 separate, and the chambers are connected again. The transmission method using connecting rods 63 and slide rails has the advantages of compact structure, smooth movement, and adjustable force amplification ratio. Moreover, since the two sliders 65 share the same slide rail, the movement axes of the upper and lower dividing plates 61 are completely coincident, avoiding misalignment during closure. At the same time, the sliding sealing connection design ensures that the dividing plates 61 remain sealed to the filter element wall during movement, preventing particles from leaking from the gaps. When the entire dividing mechanism 6 cooperates with the magnetic adsorption mechanism 5, it can first enrich complete magnetic resin particles on one side of the filter element, and then quickly close the dividing plates 61 to achieve precise isolation.

[0029] As one embodiment, the specific transmission structure of the adjustable spacing component 66 is further defined. This structure utilizes the existing power of the rotating shaft 53 in the magnetic adsorption mechanism 5 to achieve linkage between adsorption and separation. Specifically, the adjustable spacing component 66 includes a first gear 661, a second gear 662, and a gear ring 663. The gear ring 663 is rotatably mounted on the top of the second processing box 2. The first gear 661 and the second gear 662 are respectively located on both sides of the top of the second processing box 2 and are both meshed with the gear ring 663 for transmission. Among them, the first gear 661 is fixedly sleeved on the rotating shaft 53, and the rotating shaft 53 is the drive shaft of the magnetic roller 51. Therefore, when the drive motor 54 drives the rotating shaft 53 to rotate, the first gear 661 rotates accordingly and transmits power to the second gear 662 through the gear ring 663. The gear ring 663 acts as a transmission mechanism. The gear 662 is used to change the direction of rotation and achieve deceleration or acceleration, depending on the gear ratio. The second gear 662 is rotatably connected to the top of the second processing box 2, and a gear shaft 664 fixed at the center of the second gear 662 extends downwards into the interior of the second processing box 2. A lead screw 665 is fixedly installed at the bottom end of the gear shaft 664. Collars 666 are fitted at both ends of the lead screw 665 and are fixedly installed on the inner wall of the second processing box 2 to support the lead screw 665, ensuring it can only rotate and not move axially. The lead screw 665 has two sections of threads with opposite directions of rotation; for example, the upper section is a right-hand thread and the lower section is a left-hand thread. Two nuts 667 are fitted on the lead screw 665, each nut 667 engaging with the corresponding thread section. The two nuts 667 are fixedly installed on the middle of the corresponding connecting rod 63. When the lead screw 665 rotates, because the two sections of threads rotate in opposite directions, the two nuts 667 will move simultaneously in opposite directions, i.e., move closer to each other or further away from each other. The two nuts 667 drive the middle parts of the two connecting rods 63 respectively, while the end sliders 65 of the connecting rods 63 are constrained by the limiting slide rails 64. Therefore, the connecting rods 63 will rotate around the hinge point, thereby changing the distance between the two connecting rods 63. The change in distance ultimately drives the dividing plate 61 to close or separate.

[0030] On the one hand, this scheme directly utilizes the drive motor 54 of the magnetic roller 51 to simultaneously drive the dividing mechanism 6, achieving synchronous adsorption and dividing. That is, when the magnetic roller 51 rotates to adsorb broken particles, the lead screw 665 also rotates, causing the dividing plate 61 to gradually close. After adsorption is completed, the dividing plate 61 completely isolates the chamber. On the other hand, by selecting the gear ratio of the first gear 661 and the second gear 662, the relationship between the closing speed of the dividing plate 61 and the rotation speed of the magnetic roller 51 can be adjusted, facilitating optimization according to actual working conditions. The lead screw 665 adopts a double-threaded design, ensuring the symmetry of the movement of the two nuts 667, thereby enabling the upper and lower dividing plates 61 to move synchronously towards each other, resulting in accurate closing positions. The collar 666 can be made of rolling bearing or wear-resistant bushing to reduce friction.

[0031] As one implementation method, an improved structure of flexible buffer pads 8 and particle-accepting pits 9 is proposed to address the potential particle damage caused by the closing of the dividing plates 61. Specifically, a flexible buffer pad 8 is provided at the end of the dividing plates 61 that is in contact with each other for closing (i.e., the end that extends into the filter element). This flexible buffer pad 8 is made of an elastomer material, such as silicone rubber, fluororubber, polyurethane elastomer, or nitrile rubber. These materials have good resilience, abrasion resistance, and water resistance, and can operate underwater for extended periods without swelling or aging. Multiple particle-accepting pits 9 are formed on the surface of the flexible buffer pad 8. These pits can be circular, elliptical, or polygonal blind holes, arranged regularly or irregularly. When the two dividing plates 61 approach and close under the drive of the adjustable spacing assembly 66, the two flexible buffer pads 8 are in contact first, rather than the rigid end faces of the dividing plates 61. Due to the compressibility of the flexible material, the buffer pads absorb the impact energy during closing, preventing vibration or noise from rigid collisions. More importantly, the particle-accommodating pit 9 provides a space to accommodate magnetic resin particles that may accidentally remain between the two dividing plates 61. If some particles are not removed in time, they will sink into the pit when the dividing plates 61 close, instead of being directly squeezed between the two rigid planes. Therefore, even if some particles are trapped, they will not be crushed, thereby reducing the generation of new broken particles due to the dividing action.

[0032] When fully closed, the flexible buffer pad 8 is compressed, and a gap remains between the rigid end faces of the two dividing plates 61. This gap ensures that even if the flexible buffer pad 8 undergoes permanent deformation after long-term use, the rigid end faces will not directly contact each other, thus protecting the dividing plates 61 themselves and preventing the particles from being crushed by the rigidity. It should be noted that the specific value of this gap can be set according to the compression and rebound characteristics of the flexible buffer pad 8 and the average particle size of the magnetic resin particles. It is usually controlled to be slightly smaller than the particle size, so that the particles cannot enter between the rigid end faces, or even if they do, they will be captured by the pits.

[0033] This solution, by adding a flexible buffer pad 8 and a particle-containing pit 9, not only protects the integrity of the particles but also extends the service life of the dividing plate 61. At the same time, due to the sealing effect of the elastomer, it further improves the reliability of the chamber isolation and prevents broken particles from leaking from the closed gaps. This reduces the probability that the particles in the isolated area may be squeezed and broken during the repeated opening and closing of the dividing plate 61, which would lead to an increase in the number of broken particles and reduce the purification effect. Example 2:

[0034] Please see Figures 4-5As shown, the magnetic resin filter element 4 is provided with corresponding filter screens 11 at the inlet and two outlets 7. A linkage mechanism 10 is provided at the filter screen 11 at one of the outlets 7. The linkage mechanism 10 is used to open the filter screen 11 after two independent chambers are formed inside the magnetic resin filter element 4.

[0035] The linkage mechanism 10 includes a pull rope 101 and a secondary baffle 102. The secondary baffle 102 is rotatably connected to the side of the lower dividing plate 61 away from the swing plate 105 via a first torsion spring. The free end of the secondary baffle 102 is set into an arc-shaped structure 103. A slot 104 is opened on the end face of the lower dividing plate 61. One end of the pull rope 101 is fixed to the arc-shaped structure 103 of the secondary baffle 102 after passing through the slot 104. The other end of the pull rope 101 is fixedly connected to the free end of the swing plate 105. An embedding groove is opened on the inner bottom wall of the magnetic resin filter element 4. One end of the embedding groove is rotatably connected to the swing plate 105 via a second torsion spring. The filter screen 11 is embedded and fixed in the middle of the swing plate 105. The torque of the second torsion spring is less than that of the first torsion spring. In the non-working state, the swing plate 105 keeps the filter screen 11 closed at the outlet 7 under the action of the second torsion spring, while the secondary baffle 102 maintains its initial position under the action of the first torsion spring.

[0036] When the lower dividing plate 61 moves upward, the pull rope 101 is pulled, and the sub-baffle 102 rotates around its hinge point under the pressure of the pull rope 101 and presses the pull rope 101. At the same time, the pull rope 101 pulls the swing plate 105 to rotate upward, so that the filter screen 11 on the swing plate 105 leaves the corresponding outlet 7.

[0037] The arc-shaped structure 103 of the sub-baffle 102 is configured as an arc-shaped sealing cover that matches the joint of the two partition plates 61. When the two partition plates 61 approach each other and are squeezed and sealed under the drive of the adjustable spacing component 66, the arc-shaped structure 103 covers the joint of the two partition plates 61, forming a sealing cover on the joint.

[0038] In this embodiment, in the initial state where the two dividing plates 61 are not closed, the lower dividing plate 61 is in a low position, the pull rope 101 is in a slack state, and under the small torque of the second torsion spring, the swing plate 105 continues to rotate downward, and the filter screen 11 embedded in its middle covers the corresponding outlet 7, and the outlet 7 is closed. Under the large torque of the first torsion spring, the auxiliary baffle 102 is in close contact with the side of the lower dividing plate 61 and does not generate additional pulling force.

[0039] When it is necessary to discharge broken resin particles, the dividing plate 61 begins to move upward. When the adjustable spacing component 66 drives the two dividing plates 61 to move closer to each other, the lower dividing plate 61 begins to move upward. As the dividing plate 61 moves upward, the pull rope 101 is gradually tensioned. Since one end of the pull rope 101 is fixed to the arc-shaped structure 103 of the auxiliary baffle 102 and passes through the slot 104 and is connected to the swing plate 105, the pull rope 101 first transmits the tension to the swing plate 105. Since the torque of the second torsion spring is less than that of the first torsion spring, the tension on the pull rope 101 first overcomes the elastic force of the second torsion spring. The swing plate 105 rotates upward around its hinge point, i.e., the end embedded in the slot, and the filter screen 11 embedded in the middle leaves the corresponding outlet 7, and the outlet 7 gradually opens. At this time, the pull rope 101 is still in a tensioned state, but the auxiliary baffle 102 has not yet rotated because the torque of the first torsion spring is large and has not yet been overcome.

[0040] As the dividing plate 61 continues to move upward, the pull rope 101 is further stretched, and the tension continues to increase. When the tension increases to a level sufficient to overcome the elastic force of the first torsion spring, the secondary baffle 102 begins to rotate around its hinge point. When the secondary baffle 102 rotates, the arc-shaped structure 103 at its free end presses against the pull rope 101 and gradually moves towards the joint of the two dividing plates 61. When the two dividing plates 61 are completely closed, dividing the interior of the magnetic resin filter element 4 into two independent chambers, the arc-shaped structure 103 of the secondary baffle 102 covers and presses against the joint of the two dividing plates 61, forming a seal to prevent damaged resin particles from leaking from the joint into the other chamber. At this time, the swing plate 105 has rotated to its maximum angle, the outlet 7 is fully opened, and the damaged magnetic resin particles are smoothly discharged from the outlet 7 under the action of gravity or water flow. When the adjustable spacing component 66 drives the dividing plate 61 to separate and reset, the lower dividing plate 61 moves downward, the pull rope 101 gradually loosens, and the tension decreases. Due to the smaller torque of the second torsion spring, the swing plate 105 first rotates in the opposite direction under the restoring force of the second torsion spring, causing the filter screen 11 to cover the outlet 7 again. Subsequently, the pull rope 101 loosens further, and the larger torque of the first torsion spring causes the auxiliary baffle 102 to rotate in the opposite direction and reset, closely adhering to the side of the dividing plate 61, while simultaneously removing the cover of the butt joint.

[0041] This solution uses a pull rope 101, a secondary baffle 102, a swing plate 105, and a first torsion spring and a second torsion spring in cooperation. On the one hand, when the lower dividing plate 61 moves upward, the pull rope 101 is tensioned and drives the swing plate 105 and the secondary baffle 102 to move in sequence. Without the need for additional sensors, controllers, or power sources, the filter screen 11 at the corresponding outlet 7 can be automatically opened while the dividing plate 61 divides the inside of the magnetic resin filter element 4 into two independent chambers, so that the damaged magnetic resin particles can be discharged smoothly. On the other hand, by setting the torque of the second torsion spring to be less than that of the first torsion spring, a mutually reinforcing timing relationship is formed between the two actions. When the pull rope 101 is pulled, the second torsion spring with less torque is overcome first, causing the swing plate 105 to rotate first and the filter screen 11 to open in advance, avoiding pressure buildup in the chamber or resin particles clogging the outlet 7 due to the filter screen 11 not being open. After the filter screen 11 is fully opened, the pull force of the pull rope 101 continues to increase and overcomes the first torsion spring with greater torque, driving the auxiliary baffle 102 to rotate and press the joint to form a seal. The above-mentioned mutually reinforcing sequence of opening the filter screen 11 first and then pressing the joint ensures the timely opening of the discharge channel and prevents damaged resin particles from entering another chamber from the joint, thereby optimizing the valve opening and sealing within a limited space, improving the discharge efficiency of damaged resin particles and the operational stability of the equipment.
