Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to an anti-clogging high-efficiency filter. Background Technology

[0002] High-efficiency particulate filters (HEPA filters), as a key final stage in various filtration systems, are primarily used to capture fine particulate dust and various suspended solids smaller than 0.5 μm. In many fields with stringent air quality requirements, such as cleanrooms in optoelectronics, LCD manufacturing, biomedicine, precision instruments, beverage and food, and PCB printing industries, HEPA filters play a vital role and are one of the core pieces of equipment ensuring that the cleanliness of the production environment meets standards.

[0003] However, in actual use, existing high-efficiency filters have many drawbacks.

[0004] On the one hand, as filtration continues, a large amount of dust and suspended matter accumulates on the filter screen, easily causing it to clog. Once clogged, the filter's ventilation resistance will increase significantly, resulting in insufficient ventilation and greatly reducing filtration efficiency, thus affecting the air quality of the production environment. On the other hand, it will also increase the energy consumption of the equipment, shorten its service life, and increase the company's operating costs.

[0005] On the other hand, replacing filter components in traditional filters is often a complex process, requiring specialized personnel with specialized tools and a considerable amount of time. This not only reduces work efficiency but may also damage the equipment due to improper operation. Furthermore, in some work scenarios requiring continuous operation, filter maintenance and replacement can lead to production interruptions, causing unnecessary economic losses for the company. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides an anti-clogging high-efficiency filter, which overcomes the shortcomings of the prior art and effectively solves the problems of easy clogging, low ventilation, poor filtration efficiency and complicated operation of replacing filter components in the existing high-efficiency filters.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A clog-resistant high-efficiency filter includes a fixed housing. A movable block is slidably connected to the top of one side of the outer wall of the fixed housing. A push rod motor is fixedly mounted on one end of the top of the movable block. A first connecting pipe is welded to the other end of the movable block. A solenoid valve and a particulate sensor are respectively fixed to the top and bottom of one side of the outer wall of the first connecting pipe. A second connecting pipe is located directly below the first connecting pipe. A fixing block is welded to one side of the outer wall of the second connecting pipe and the fixed housing. A fixing plate is welded to the other side of the outer wall of the second connecting pipe. A rotating rod is rotatably connected to the top. A support ring is sleeved and fixed to the rod wall of the rotating rod, and a threaded ring is screwed to the top of the rod wall. A filter assembly sleeved on the rod wall is clamped between the threaded ring and the support ring. The filter assembly includes a connecting ring, an inner ring disposed outside the connecting ring, an outer ring disposed outside the inner ring, a connecting rod welded and fixed at equal intervals along the ring between the outer ring wall of the connecting ring and the inner ring wall, and between the outer ring wall of the inner ring and the inner ring wall of the outer ring, and a filter screen welded and fixed at equal intervals along the ring between the outer ring wall of the inner ring and the inner ring wall of the outer ring.

[0009] Preferably, a sliding groove for sliding engagement is provided on the top of the outer wall of one side of the fixed shell, and the tail end of the push rod motor is installed and fixed on the top inner wall of the sliding groove.

[0010] Preferably, the inner walls on both sides of the slide groove are provided with strip grooves, and one end of the outer wall on both sides of the movable block is welded and fixed with a slider, and the slider and the strip groove form a sliding fit.

[0011] Preferably, a servo motor is fixedly mounted on the bottom of the fixing plate, and the output shaft of the servo motor is connected and fixed to the bottom end of the rotating rod through a coupling.

[0012] Preferably, the rotating rod has a limiting block welded and fixed on both sides of its rod wall, which is located at the top of the support ring. The height of the limiting block is the same as the height of the connecting ring. The inner walls of the connecting ring are provided with slots that can be inserted into the limiting blocks. The top of the rotating rod wall is engraved with threads, and the bottom of the threads is flush with the height of the limiting blocks.

[0013] Preferably, sealing rings are bonded and fixed to the bottom of the first connecting pipe and the top of the second connecting pipe, and the ends of the two sealing rings that are close to each other are set as interlocking concave-convex structures, and the distance between two adjacent connecting rods between the inner ring and the outer ring is greater than the outer diameter of the sealing ring.

[0014] Preferably, mounting blocks are welded and fixed to both outer walls of the fixed shell, and the bottom of the fixed shell is a cavity structure. A battery and a controller are installed in the cavity, and the solenoid valve, particulate sensor and servo motor are all electrically connected to the controller.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. By designing a unique filter assembly consisting of a connecting ring, inner ring, outer ring, connecting rod, and filter screen, the multi-structure design and the ring-shaped distribution of the filter screen increase the filter's lifespan, allowing it to capture particulate matter for a longer period. The controller sets time intervals based on the usage environment. After each interval, the controller activates a push rod motor, which retracts, moving the movable block and its connected first connecting pipe upwards. The first connecting pipe separates from the second connecting pipe, and then a servo motor activates, driving a rotating rod to rotate, thus rotating the filter assembly. During rotation, the unblocked filter screen portion rotates to the channel position between the first and second connecting pipes, continuing its efficient filtration work, effectively avoiding the overall filtration efficiency decrease caused by localized filter screen blockage. Compared to traditional single-screen filters, the multi-layer filter structure of this invention significantly increases the filtration volume per unit time, ensuring high ventilation and stable filtration efficiency even during prolonged use.

[0017] 2. Replacing the filter assembly is extremely simple. A particulate matter sensor monitors the particulate matter concentration on the unreplaced filter screen on one side of the first connecting tube in real time. When the concentration exceeds a set threshold, it indicates potential clogging. The controller then sends a replacement reminder to the corresponding app on the operator's mobile phone. The operator replaces the filter assembly by using a push rod motor to separate the first and second connecting tubes. The screw ring is then unscrewed. Because the rotating rod has limit blocks on both sides, and the connecting ring has slots on both sides that match the limit blocks, the connecting ring will not rotate freely. Simply lift it upwards to easily remove the filter assembly from the rotating rod. To install a new filter assembly, align the slot of the connecting ring with the limit block, insert it, and then tighten the screw ring to complete the installation. The entire replacement process requires no complex tools or professional personnel, significantly saving time and labor costs. Compared to traditional filters where replacing filter components requires disassembling numerous parts and involves cumbersome procedures that can easily damage the equipment, this invention greatly improves the efficiency and convenience of maintenance, reduces the difficulty and cost of equipment maintenance, and is especially suitable for work scenarios that require frequent replacement of filter components.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example:

[0025] Reference Figure 1-4 A clog-resistant high-efficiency filter includes a fixed housing 1. A movable block 3 is slidably connected to the top of one side of the outer wall of the fixed housing 1. A push rod motor 5 is fixedly installed at one end of the top of the movable block 3, and a first connecting pipe 6 is welded to the other end of the movable block 3. A solenoid valve 7 and a particulate sensor 8 are respectively fixedly installed at the top and bottom of one side of the outer wall of the first connecting pipe 6. A second connecting pipe 9 is located directly below the first connecting pipe 6. A fixing block 10 is welded to one side of the outer wall of the second connecting pipe 9 and the fixed housing 1. A fixing plate 11 is welded to the other side of the outer wall of the second connecting pipe 9. A rotating rod 12 is rotatably connected to the top of the fixing plate 11. A support ring 14 is sleeved and fixed to the rod wall of the rotating rod 12. A screw ring 16 is screwed to the top of the rod wall of the rotating rod 12. A filter assembly 18 sleeved on the rod wall of the rotating rod 12 is clamped between the screw ring 16 and the support ring 14. The filter assembly 18 includes a connecting ring 19, an inner ring 20 disposed outside the connecting ring 19, an outer ring 21 disposed outside the inner ring 20, a connecting rod 22 welded and fixed at equal intervals along the ring between the outer ring wall of the connecting ring 19 and the inner ring wall of the inner ring 20, and between the outer ring wall of the inner ring 20 and the inner ring wall of the outer ring 21, and a filter screen 23 welded and fixed at equal intervals along the ring between the outer ring wall of the inner ring 20 and the inner ring wall of the outer ring 21.

[0026] A sliding groove for a sliding fit is formed by a movable block 3 on the top of one side of the outer wall of the fixed shell 1. The tail end of the push rod motor 5 is fixedly mounted on the top inner wall of the sliding groove. Strip grooves are formed on both sides of the inner wall of the sliding groove. A slider 4 is welded to one end of each side of the outer wall of the movable block 3, and the slider 4 slides into the strip groove. A servo motor 13 is fixedly mounted on the bottom of the fixed plate 11. The output shaft of the servo motor 13 is connected and fixed to the bottom end of the rotating rod 12 via a coupling. Limiting blocks 15 located on the top of the support ring 14 are welded to both sides of the rotating rod 12. The height of the limiting blocks 15 is the same as the height of the connecting ring 19. Slots for insertion fit with the limiting blocks 15 are formed on both sides of the inner wall of the connecting ring 19. Threads are engraved on the top of the rotating rod 12, and the bottom of the threads is flush with the height of the limiting blocks 15. Sealing rings 17 are bonded and fixed to the bottom of the first connecting pipe 6 and the top of the second connecting pipe 9. The ends of the two sealing rings 17 that are close to each other are set as interlocking concave-convex structures. The distance between two adjacent connecting rods 22 located between the inner ring 20 and the outer ring 21 is greater than the outer diameter of the sealing ring 17. Mounting blocks 2 are welded and fixed to both outer walls of the fixed shell 1. The bottom of the fixed shell 1 is a cavity structure. A battery and a controller are installed in the cavity. The solenoid valve 7, the particulate sensor 8 and the servo motor 13 are all electrically connected to the controller.

[0027] When installing this anti-clogging high-efficiency filter, firstly, the mounting blocks 2, which are welded and fixed to the outer walls of both sides of the fixed housing 1, are used to install the fixed housing 1 in a suitable position. The mounting blocks 2 can be securely connected to the external mounting bracket through bolts or other connectors to ensure that the fixed housing 1 is firmly installed. The battery in the cavity at the bottom of the fixed housing 1 powers the entire device, while the controller is used to control the operation of various electrical components. The movable block 3 forms a sliding fit with the strip grooves on both sides of the inner wall of the slide groove on the top of one side of the fixed housing 1 through the slider 4. This design makes the sliding of the movable block 3 in the slide groove smoother and less prone to deviation or jamming. The push rod motor 5 is installed on the inner wall of the top of the slide groove, and its tail end is fixed. After starting, it can drive the movable block 3 to move up and down along the slide groove. The first connecting pipe 6 is welded and fixed to the other end of the movable block 3. When the movable block 3 moves, the first connecting pipe 6 also moves synchronously.

[0028] The installation process of the filter assembly 18 is as follows: The connecting ring 19 of the filter assembly 18 is fitted onto the rotating rod 12, aligning the slots on both sides of the inner wall of the connecting ring 19 with the limiting blocks 15 on both sides of the rotating rod 12, ensuring accurate installation and preventing arbitrary rotation. Next, the screw ring 16 is screwed onto the top of the rotating rod 12. By tightening the screw ring 16, it works in conjunction with the support ring 14 to firmly clamp the filter assembly 18 between them. The bottom end of the rotating rod 12 is connected and fixed to the output shaft of the servo motor 13 via a coupling. The servo motor 13 is mounted on the bottom of the fixed plate 11. When the servo motor 13 starts, its output shaft drives the rotating rod 12 to rotate, thereby driving the filter assembly 18 to rotate.

[0029] Sealing rings 17 are bonded and fixed to the bottom of the first connecting pipe 6 and the top of the second connecting pipe 9. Under normal operating conditions, when the first connecting pipe 6 and the second connecting pipe 9 are connected, the sealing rings 17 effectively prevent airflow leakage, ensuring the sealing performance of the filtration system. The distance between two adjacent connecting rods 22 located between the inner ring 20 and the outer ring 21 is greater than the outer diameter of the sealing ring 17, so that the sealing ring 17 will not interfere with the connecting rods 22 during the connection or separation of the first connecting pipe 6 and the second connecting pipe 9. The solenoid valve 7 and the particulate sensor 8 are respectively installed at the top and bottom of one side of the outer wall of the first connecting pipe 6. The solenoid valve 7 controls the flow of fluid in the first connecting pipe 6, while the particulate sensor 8 monitors the concentration of airborne particles on the filter screen 23 in real time and transmits the data to the controller.

[0030] Working principle:

[0031] When this anti-clogging high-efficiency filter is in operation, the particulate matter sensor 8 continuously monitors the particulate matter concentration on the unreplaced filter screen 23 on one side of the first connecting pipe 6 and transmits the monitoring data to the controller in real time. In the initial stage, when the particulate matter concentration is low, indicating that the filter screen 23 of the filter assembly 18 is not clogged or is only slightly clogged, the solenoid valve 7 remains open. Fluid enters the filter assembly 18 through the channel formed by the bottom of the first connecting pipe 6 and the top of the second connecting pipe 9. As air passes through the filter assembly 18, the filter screen 23 intercepts and filters dust and suspended matter in the fluid. The filtered clean fluid flows out from the second connecting pipe 9 and enters the subsequent working area requiring clean fluid.

[0032] As filtration continues, after a short period, solenoid valve 7 closes, preventing unfiltered fluid from entering filter assembly 18. The controller then starts push rod motor 5. Push rod motor 5 drives movable block 3 upwards along the groove on the top of the outer wall of fixed housing 1, thereby moving the first connecting pipe 6 upwards. The first connecting pipe 6 gradually separates from the second connecting pipe 9. Next, the controller starts servo motor 13. The output shaft of servo motor 13 drives rotating rod 12 via coupling. Since the connecting ring 19 of filter assembly 18 is engaged with limiting blocks 15 on both sides of the rotating rod 12 via slots, the rotating rod 12 drives the filter assembly 18 to rotate synchronously. During rotation, the originally clogged filter screen 23 gradually deviates from the fluid channel, while the unclogged or less clogged parts of filter screen 23 rotate to the fluid channel position. Once the appropriate position is reached, the controller stops servo motor 13. Subsequently, the controller controls push rod motor 5 to work in reverse, moving movable block 3 and the first connecting pipe 6 downwards, causing the first connecting pipe 6 to reconnect with the second connecting pipe 9. At this time, the solenoid valve 7 opens again, and the fluid can enter the filter assembly 18 through the first connecting pipe 6. The filter screen 23, which has now rotated to the fluid channel position, filters the fluid, thereby ensuring that the filter can continue to work efficiently.

[0033] If the dust and suspended matter accumulated on filter screen 23 gradually increase, causing the particulate matter concentration on filter screen 23 to rise and exceed the preset threshold of the controller, the particulate matter sensor 8 will send this signal back to the controller. After receiving the signal, the controller will send a replacement reminder to the app downloaded on the operator's mobile phone. At this time, the solenoid valve 7 will close to prevent unfiltered fluid from continuing to enter the filter assembly 18, so that the operator can replace the filter assembly 18.

[0034] When replacing the filter assembly 18, the controller controls the push rod motor 5 to separate the first connecting pipe 6 from the second connecting pipe 9. Then, the screw ring 16 is manually unscrewed. Due to the limiting block 15, the connecting ring 19 will not rotate freely, and the filter assembly 18 can be lifted directly upwards to remove it from the rotating rod 12. After installing the new filter assembly 18 onto the rotating rod 12 in the same manner, the controller again controls the push rod motor 5 to align the first connecting pipe 6 with the second connecting pipe 9, thus completing the replacement of the filter assembly 18. The entire process is simple and convenient.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
