Description
Technical Field
[0001] The utility model relates to the technical field of high-efficiency filters, in particular to a W-shaped high-efficiency filter with a large filtration area and low resistance. Background Art
[0002] The filter adopts a unique W-shaped structure, which greatly increases the surface area of the filter medium. Compared with the traditional flat filter, the W-shaped structure can provide more filtration area in the same space, thereby improving the filtration efficiency, enabling air or other media to fully contact the filter impurities when passing through the filter, increasing the filtration opportunities, and effectively capturing the tiny particles and pollutants therein.
[0003] The following problems will occur when the large-filtration-area W-shaped filter in the prior art is in use: 1. As the use time increases, the filter screen surface may be deformed, blocked or damaged, resulting in a decrease in filtration accuracy and inability to always ensure the effective interception of tiny particles. Although it has the advantage of low resistance in the initial state, after long-term operation, due to the accumulation of particles such as dust on the filter medium, the resistance may gradually increase, affecting the air circulation efficiency and system energy consumption; 2. The complex W-shaped structure is not easy to disassemble, and once disassembled, it is necessary to wait, wasting working time.
[0004] Therefore, a W-shaped high-efficiency filter with a large filtration area and low resistance is needed to solve the above problems. Summary of the Utility Model
[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a W-shaped high-efficiency filter with a large filtration area and low resistance is proposed.
[0006] To achieve the above purpose, the utility model adopts the following technical scheme: A W-shaped high-efficiency filter with a large filtration area and low resistance, including a box body, a first filter screen layer and a second filter screen layer. The top of the box body is clamped with a top frame, the top frame is bolted with a support plate, the bottom of the support plate is mortise-and-tenon connected with a filter plate, the top of the filter plate is provided with a top joint, and the filter plate is connected with the support plate through the top joint. Clamping openings are formed on both sides inside the filter plate, a side opening is arranged on one side of the clamping opening, a clamping groove is arranged on the other side of the side opening, and an activated carbon mesh layer is clamped inside the clamping groove.
[0007] Preferably, the positions of the clamping openings and the clamping grooves on both sides inside the filter plate are different. Telescopic springs are connected to both sides inside the clamping openings, magnetic attraction clamping pieces are clamped at the ends of the telescopic springs, and the two magnetic attraction clamping pieces attract each other.
[0008] Preferably, openings are formed on the fronts of the first filter screen layer, the second filter screen layer and the activated carbon mesh layer.
[0009] Preferably, barbs are annularly arrayed on the back of the openings of the first filter screen layer and the second filter screen layer.
[0010] Preferably, an infrared sensor is embedded on one side of the front surface of the top of the filter plate, a micro motor is installed on one side inside the top of the filter plate, a sliding block is externally threadedly connected to the output end of the micro motor, and the sliding block is slidably connected to the top inside the filter plate.
[0011] Preferably, a connecting shaft is threadedly connected to the bottom end of the sliding block, a first filter screen layer is wound around the outside of the connecting shaft, and a sleeve piece is clamped on one side of the first filter screen layer.
[0012] Preferably, a roller is threadedly connected to the bottom end of the connecting shaft, a groove is provided at the bottom inside the filter plate, and the roller is adapted to the groove at the bottom inside the filter plate.
[0013] Beneficial effects
[0014] In the present utility model, the three-layer structure inside the box body, namely the first filter screen layer, the second filter screen layer and the activated carbon mesh layer, forms an efficient filtering system. The first filter screen layer serves as a preliminary filtering layer, which can intercept larger particle impurities and relieve the burden for subsequent filtering links. The second filter screen layer serves as a standby layer, which can be quickly put into use when the first filter screen layer is blocked or needs maintenance to ensure the continuity of the filtering process. The activated carbon mesh layer is mainly responsible for adsorbing odor molecules in the waste medium and effectively improving the air quality after filtering. This multi-stage filtering design not only improves the filtering efficiency but also extends the service life of the entire filtering system. Different levels of filter screens and activated carbon can be optimized according to their specific functions and filtering requirements to achieve the best filtering effect. When there is a medium impacting the mesh layer, the top surface of the mesh layer will be pressed down, and the impurities in the openings will be pried open by the barbs. This design utilizes the impact force of the medium flow, enabling the mesh layer to automatically clean part of the blockage during the filtering process. Compared with traditional static filter screens, this dynamic anti-blocking mechanism can greatly reduce the possibility of filter screen blockage, improve the stability and reliability of the filtering system. The barbs are annularly arrayed on the back of the openings, which can comprehensively respond to medium impacts from different directions, ensuring that impurities can be promptly pried open and discharged from the mesh layer to avoid the accumulation of blockages. Since the barbs can clean part of the blockage in time, the service life of the mesh layer is also extended. The need for frequent filter screen replacement is reduced, and the maintenance cost is lowered.
[0015] In this utility model, when the first filter screen layer becomes blocked or requires maintenance, the spare second filter screen layer can be quickly put into use to ensure that the filtering process will not be interrupted. This can maintain the continuous operation of the equipment and avoid work stoppages or production interruptions caused by filter screen blockages. Especially in scenarios with strict requirements for continuous filtration, such as industrial production and medical facilities, it ensures the stability and reliability of the system. Under different working conditions, different types and concentrations of impurities may be faced. At the same time, by alternately using different filter screen layers, the usage time and burden of a single filter screen can be reduced, thereby extending the overall service life of the filter screen. This not only reduces the frequency and cost of replacing the filter screen but also reduces the maintenance workload and equipment downtime caused by frequent filter screen replacements.

Detailed Implementation Manner
[0026] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the following further elaborates the present utility model in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.
[0027] The following describes the specific embodiments of the present utility model in conjunction with the drawings. Specific Embodiment 1:
[0029] Referring to Figure 1-8 , a W-shaped large filtration area low-resistance high-efficiency filter, comprising a box body 1, a first filter screen layer 6 and a second filter screen layer 8. A top frame 2 is clamped at the top of the box body 1. A frame plate 4 is bolted to the top frame 2. A filter plate 3 is mortise-connected to the bottom of the frame plate 4. A top joint 5 is provided at the top of the filter plate 3. The filter plate 3 is connected to the frame plate 4 through the top joint 5. Clamping openings 12 are formed on both sides inside the filter plate 3. A side opening 19 is provided on one side of the clamping opening 12. A clamping opening 20 is provided on the other side of the side opening 19. An activated carbon mesh layer 9 is clamped inside the clamping opening 20.
[0030] In this device, the external structure of the box body 1 is the same as that of the W-shaped filter in the prior art. There are three layers inside the box body 1, namely the first filter screen layer 6, the second filter screen layer 8 and the activated carbon mesh layer 9. Among them, the second filter screen layer 8 is spare. In the initial state, the second filter screen layer 8 is rolled up. And activated carbon powder is sewn inside the activated carbon mesh layer 9, which can filter out the odor in the waste medium.
[0031] Openings 7 are formed on the front surfaces of the first filter screen layer 6, the second filter screen layer 8 and the activated carbon mesh layer 9. Hook-shaped fasteners 10 are annularly arranged at the back of the openings 7 of the first filter screen layer 6 and the second filter screen layer 8. The openings 7 on the front surfaces of the first filter screen layer 6, the second filter screen layer 8 and the activated carbon mesh layer 9 are used for filtration, while the hook-shaped fasteners 10 annularly arranged at the back of the openings 7 are used to prevent blockage. When there is a medium impacting the mesh layer, the top surface of the mesh layer will be pressed down, so that the impurities in the openings 7 will be pried open by the hook-shaped fasteners 10 and are not easily blocked. Specific Embodiment 2:
[0033] Referring to Figure 1-8 , the positions of the clamping openings 12 and the clamping openings 20 on both sides inside the filter plate 3 are different. Telescopic springs 18 are connected to both sides inside the clamping openings 12. Magnetic attraction clamping pieces 17 are clamped at the ends of the telescopic springs 18. The two magnetic attraction clamping pieces 17 on both sides attract each other.
[0034] The installation directions of the first filter screen layer 6 and the second filter screen layer 8 inside the filter plate 3 are opposite. As Figure 5-7 shown,
[0035] On one side of the front of the top of the filter plate 3, an infrared sensor 11 is embedded. On one side inside the top of the filter plate 3, a micro motor is installed. The output end of the micro motor is externally threadedly connected with a sliding block 13, and the sliding block 13 is slidably connected to the top inside the filter plate 3.
[0036] The bottom end of the sliding block 13 is threadedly connected with a connecting shaft 14. A first filter screen layer 6 is wound around the outside of the connecting shaft 14. One side of the first filter screen layer 6 is clamped with a sleeve piece 15.
[0037] The bottom end of the connecting shaft 14 is threadedly connected with a roller 16. A groove is provided at the bottom inside the filter plate 3, and the roller 16 and the groove at the bottom inside the filter plate 3 are mutually adapted.
[0038] When the infrared sensor 11 detects that the surface of the first filter screen layer 6 is seriously blocked, it will first automatically control the second filter screen layer 8 to open and work instead of the first filter screen layer 6, while the first filter screen layer 6 will be retracted. When the infrared sensor 11 detects that the surface of the first filter screen layer 6 is seriously blocked, it will also transmit a signal to the staff to remind the staff on one side.
[0039] The detailed steps are as follows:
[0040] I. Initial state
[0041] Before the entire filtering device is started, the filter plate 3 is in the initial state. The first filter screen layer 6 and the second filter screen 8 layer are installed in opposite directions and are located inside the filter plate 3. The magnetic attraction clips 17 in the clamping opening 12 attract each other under the action of the telescopic spring 18 to ensure the stability of the filter screen assembly in the non-working state. The infrared sensor 11 is in the monitoring state, the micro motor is not started, the sliding block 13 is in the initial position, the first filter screen layer 6 on the connecting shaft 14 is in the ready-to-work state, the roller 16 is located in the groove at the bottom inside the filter plate, and a sealing treatment is performed so that the fluid will not leak. It should be noted that a sealing gasket can be used for the sealing treatment here, and the sealing is carried out according to the actual situation.
[0042] II. The start of the filtering work
[0043] During the normal filtering process, when the filtering system starts to operate, the fluid passes through the filter plate 3 and first passes through the first filter screen layer 6 for preliminary filtering to intercept larger particulate impurities. The first filter screen layer 6 is assisted by the magnetic attraction clips 17 and the telescopic spring 18 in the clamping opening 12 to maintain a stable filtering state, ensuring that the fluid can pass through the filter screen evenly. The magnetic attraction clips 17 in the clamping opening 12 will clamp the sleeve piece 15 on the side of the filter screen layer to fix it.
[0044] The infrared sensor 11 continuously monitors the clogging condition of the surface of the first filter layer 6. The infrared sensor 11 determines the degree of clogging on the surface of the first filter layer 6 by emitting infrared rays and receiving the reflected signals. When the clogging condition gradually worsens, the reflected signals will change. The infrared sensor 11 determines whether the clogging is severe according to a preset threshold. Once the infrared sensor 11 detects that the surface of the first filter layer 6 is severely clogged, it will immediately send out a signal to first control the second filter layer 8 to open.
[0045] During the process of the second filter layer 8 opening, through the driving device inside it, the filter screen is quickly unfolded and occupies the filtering position, replacing the first filter layer 6 to continue the filtering work. At this time, the flow direction of the fluid automatically switches to the second filter layer 8 to ensure the continuous progress of the filtering work.
[0046] The infrared sensor 11 sends an instruction to the micro motor 17 to start the micro motor. The output end of the micro motor rotates, driving the sliding block 13 connected by threads to slide on the top inside the filter plate 3. When the output end rotates clockwise, the sliding block 13 will rotate to one side. When the output end rotates counterclockwise, the sliding block 13 will slide to the other side. It should be noted that the driving structures of the first filter layer 6 and the second filter layer 8 are the same. At the same time, the sliding block 13 and the micro motor are both hidden inside the top of the filter plate 3 without affecting the filtering. It should be noted that a motor structure is also installed at the connection between the top of the coupling shaft 14 and the sliding block 13 to drive the coupling shaft 14 to rotate for facilitating winding and unfolding. When the first filter layer 6 is wound around the outside of the coupling shaft 14, as the sliding block 13 moves, the first filter layer 6 is gradually wound around the coupling shaft 14. The roller 16 at the bottom end of the coupling shaft 14 rolls in the groove at the bottom inside the filter plate 3 to ensure the smooth progress of the process of the first filter layer 6 being retracted. It should be noted that during the retraction, the filter layer assembly will return to the clamping port 12 along with the driving assembly. When it is fully unfolded, the driving assembly of the filter layer assembly will reach the side port 19 on the opposite side. It should be noted that both the side port 19 and the clamping port 12 are sealed.
[0047] The infrared sensor 11 is built-in with a transmission chip, and the corresponding receiving chip is implanted in the micro motor. After detecting severe clogging, it will first transmit signals to the micro motor of the second filter layer 8 and the motor at the bottom of the corresponding sliding block 13. After receiving the signal, the micro motor of the second filter layer 8 will control the output end to rotate clockwise. When the micro motor rotates clockwise, it will drive the components at the bottom to move to the opposite side through the sliding block 13. At the same time, the motor at the bottom of the sliding block 13 will drive the coupling shaft 14 to rotate clockwise, causing the second filter layer 8 to fully open.
[0048] After the micro-motor of the first filter layer 6 receives a signal, the micro-motor will control the output end to rotate counterclockwise. In this way, the slider 13 and the components connected to the bottom will slide back. At the same time, after the motor corresponding to the bottom of the slider 13 receives a signal, it will drive the coupling 14 to rotate counterclockwise, realizing the winding of the first filter layer 6. When it is detected that the surface of the first filter layer 6 is severely blocked, a signal will also be transmitted to the staff. The signal can be transmitted to the staff's monitoring equipment, such as a computer, a mobile phone or a dedicated monitoring system, in a wired or wireless manner. The signal can include information such as the degree of blockage, the state of the filter layer components, and a reminder for maintenance, so that the staff can timely understand the operation of the filtration system and take corresponding measures.
[0049] For the severely blocked first filter layer 6, it can be removed from the coupling 14 for cleaning or replacement. Appropriate cleaning agents and cleaning methods can be used in the cleaning process to remove impurities and blockages on the surface of the filter. If the first filter layer 6 is severely damaged and cannot be used continuously, a new filter layer needs to be replaced.
[0050] After completing the maintenance or replacement of the first filter layer 6, the staff can reinstall it into the filter plate 3. By controlling the micro-motor, the first filter layer 6 is unfolded and restored to the initial filtering position. At the same time, according to the actual situation, the parameters and thresholds of the infrared sensor 11 can be adjusted to ensure that it can accurately monitor the blockage of the mesh layer. Finally, start the filtration system to make it resume normal filtration work.
[0051] To sum up:
[0052] 1. On the front surfaces of the first filter layer 6, the second filter layer 8 and the activated carbon mesh layer 9 in this device, openings 7 are provided. On the back of the openings 7 of the first filter layer 6 and the second filter layer 8, hook-shaped fasteners 10 are arranged in a circular array. The openings 7 on the front surfaces of the first filter layer 6, the second filter layer 8 and the activated carbon mesh layer 9 are used for filtration, while the hook-shaped fasteners 10 arranged in a circular array on the back of the openings 7 are used to prevent blockage. When there is a medium impacting the mesh layer, the top surface of the mesh layer will be pressed down, so that the impurities in the openings 7 will be pried open by the hook-shaped fasteners 10 and are not easily blocked.
[0053] 2. Normal Filtration Process When the filtration system starts to operate, the fluid passes through the filter plate 3 and first undergoes preliminary filtration through the first filter layer 6 to intercept impurities with larger particles. With the assistance of the magnetic clamping piece 17 and the telescopic spring 18 within the clamping opening 12, the first filter layer 6 maintains a stable filtration state, ensuring that the fluid can pass through the filter screen evenly. Inside the clamping opening 12, the magnetic clamping piece 17 clamps the sleeve piece 15 on the side of the filter screen layer. The infrared sensor 11 continuously monitors the clogging condition on the surface of the first filter layer 6. The infrared sensor 11 determines the degree of clogging on the surface of the first filter layer 6 by emitting infrared rays and receiving the reflected signals. When the clogging condition gradually worsens, the reflected signal will change. The infrared sensor 11 determines whether the clogging is severe based on a preset threshold. Once the infrared sensor 11 detects that the clogging on the surface of the first filter layer 6 is severe, it will immediately send a signal to first control the second filter layer 8 to open. During the opening process of the second filter layer 8, through the driving device inside it, the filter screen is quickly unfolded and occupies the filtration position to continue the filtration work instead of the first filter layer 6. At this time, the flow direction of the fluid automatically switches to the second filter layer 8 to ensure the continuous progress of the filtration work. The infrared sensor 11 sends an instruction to the micro-motor to start the micro-motor. The output end of the micro-motor rotates, driving the sliding block 13 connected by a thread to slide on the top inside the filter plate 3. When the output end rotates clockwise, the sliding block 13 will rotate to one side, and when the output end rotates counterclockwise, the sliding block 13 will slide to the other side. It should be noted that the driving structures of the first filter layer 6 and the second filter layer 8 are the same. At the same time, both the sliding block 13 and the micro-motor 7 are hidden inside the top of the filter plate 3 without affecting the filtration. When the sliding block 13 moves, it winds up the first filter layer 6 through the coupling shaft 14. A motor structure is also installed at the connection between the top end of the coupling shaft 14 and the sliding block 13 to drive the coupling shaft 14 to rotate for facilitating winding up and unfolding. When the coupling shaft 14 winds up the first filter layer 6 externally, as the sliding block 13 moves, the first filter layer 6 is gradually wound around the coupling shaft 14. The roller 16 at the bottom end of the coupling shaft 14 rolls in the groove at the bottom inside the filter plate 3 to ensure the smooth progress of the process of winding up the first filter layer 6. It should be noted that during winding up, the filter screen layer assembly will return to the clamping opening 12 along with the driving assembly. When fully unfolded, the driving assembly of the filter screen layer assembly will come to the side opening 19 on the opposite side.
