Description

Technical Field

[0001] This invention belongs to the technical field of V-type filters, and specifically relates to a V-type high-efficiency explosion-proof filter with dust suppression function. Background Technology

[0002] With the ever-increasing demands for high-cleanliness environments in modern industrial production, the importance of air filtration technology is becoming increasingly prominent. V-type filters, as a highly efficient air filtration device, occupy a key position in large-volume ventilation systems and are widely used in power plants, cleanrooms, and other locations. Thanks to their superior performance, they can effectively capture fine particles larger than 0.3μm, achieving a filtration efficiency of over 99.99%. Their unique V-shaped folded structure design, cleverly composed of multiple plateless filter elements installed within a galvanized steel plate or plastic frame, significantly increases the filtration area while effectively reducing operating resistance, thus saving considerable energy consumption. Due to these advantages, V-type filters are widely used in cleanrooms in industries such as optoelectronics, biomedicine, and food and beverage. They can serve as final-stage filters or pre-filters before ultra-high-efficiency filters, playing a vital role in ensuring the cleanliness of the production environment. However, existing V-type high-efficiency explosion-proof filters still have the following drawbacks during use: In typical usage scenarios, existing V-type filters are usually directly connected to the exhaust ducts in the production workshop. This allows dust, impurities, and other pollutants from the production area to enter the filter without hindrance. Ordinary filters lack effective dust prevention at the air inlet, and over time, a large amount of dust and impurities accumulate in both the pre-treatment and filtration areas. These accumulated pollutants easily clog the filters, and ordinary filters do not have the ability to clean themselves. Once clogged, the equipment will not function properly, forcing staff to frequently disassemble and clean it. This not only increases the workload but also severely affects the filter's efficiency, causing numerous inconveniences to the production process. Existing V-type explosion-proof filters lack the function of automatically collecting the dust and impurities after cleaning. This causes a large amount of dust to accumulate at the front and back ends of the filter. If this dust is not collected and treated for a long time, it will float around inside the equipment with the airflow at the inlet and re-attach to the filter end. This not only aggravates the equipment blockage problem and causes the equipment to malfunction, but also significantly shortens the service life of the equipment and increases the company's operating costs.

[0003] Therefore, it is necessary to invent a V-type high-efficiency explosion-proof filter with dust suppression function to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a V-type high-efficiency explosion-proof filter with dust suppression function, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a V-type high-efficiency explosion-proof filter with dust suppression function, comprising a filter body, an air inlet hood, and a protective cover. The upper end of the air inlet hood is provided with a dust removal mechanism and a dust collection assembly distributed inside and outside. The air inlet hood is installed on the front of the filter body, and the protective cover is fitted on the outside of the filter body. The dust removal mechanism includes electric cylinders installed at the lower edges of both sides of the outer wall of the air intake hood. The output ends of the two electric cylinders are each connected to a push shaft. A first connecting frame is fixedly installed between one end of the two push shafts. A first connecting rod is fixedly installed at both ends of the bottom of the first connecting frame. A first scraper is fixedly connected to one end of each of the two first connecting rods through the inner walls of both ends of the air intake hood. A plurality of second connecting frames are fixedly installed at equal intervals on one side of the first connecting frame. A second connecting rod is fixedly installed at the bottom of each second connecting frame. A second scraper is fixedly connected to one end of each second connecting rod through the inner wall of the protective cover and the inner wall of the filter body. A connecting pipe is installed on one side of the protective cover. A pressure sensor is installed on the top of the connecting pipe. Wires are connected to both sides of the pressure sensor. The two electric cylinders are electrically connected to the pressure sensor through two wires respectively. Preferably, a pressure sensor is slidably connected to the outer wall of each of the second connecting rods, a spring is fixedly provided at the bottom of each pressure sensor, the bottom of each spring is fixedly connected to the top of the protective cover, and each pressure sensor is electrically connected to two electric cylinders.

[0006] Preferably, a first dustproof net is installed between the inner wall of the filter body and the inner wall of the air inlet hood, and one side of the first scraper contacts one side of the first dustproof net. Multiple filter plates are installed at equal intervals in a V-shape on the inner wall of one end of the filter body, and the outer wall of each second scraper contacts one side of each filter plate.

[0007] Preferably, the dust collection assembly includes multiple conical grooves equally spaced at the bottom of the inner wall of the filter body, multiple discharge pipes equally spaced at the bottom of the protective cover, a V-shaped collection trough installed at the bottom of the air inlet cover, and multiple connecting pipes equally spaced at the bottom of the inner wall of the protective cover, with the inner walls at both ends of each connecting pipe communicating with the inner walls of each conical groove and each discharge pipe, respectively.

[0008] Preferably, the top of the V-shaped collecting trough is provided with multiple feeding troughs at equal intervals. Each feeding trough has a baffle rotatably connected to one side of its inner wall. Each baffle has a torsion spring fixedly connected to the outer wall at both ends. Each torsion spring is fixedly connected to the inner wall at both ends of the V-shaped collecting trough.

[0009] Preferably, an installation groove is provided on one side of the outer wall of the V-shaped collection trough, an exhaust fan is installed on the inner wall of the installation groove, a second dustproof net is installed at the edge of one side of the inner wall of the installation groove, and multiple connecting holes are provided at equal intervals on the other side of the outer wall of the V-shaped collection trough, and the inner wall of the other end of each discharge pipe is connected to the inner wall of each connecting hole.

[0010] Preferably, a protective plate is hinged to one side of the bottom of the V-shaped material trough, a handle is fixedly installed at the edge of the bottom side of the protective plate, and a limit strip is rotatably connected to one side of the bottom of the V-shaped material trough, with one side of the limit strip contacting one side of the protective plate.

[0011] Preferably, a control switch is installed on one side of the outer wall of the filter body, and the air pressure sensor, pressure sensor, electric cylinder and exhaust fan are all electrically connected to an external power supply through the control switch.

[0012] The technical effects and advantages of this invention are as follows: Under prolonged filtration and interception, the dust and impurities attached to the upper part of the first dustproof net and filter plate of this invention increase, thereby reducing the flow of air in the air intake port area and increasing the pressure in the exhaust area at the rear end of the connecting pipe. When the pressure increases, the air pressure sensor installed on the connecting pipe can sense the increased air pressure and trigger it. After triggering, it controls the electric cylinders on both sides of the air intake hood to start retracting the push shaft, which lowers the first and second connecting frames. Then, driven by the first and second connecting rods, the first and second scrapers move up and down synchronously within the air intake hood and filter body, thereby scraping off the dust and impurities attached to the first dustproof net and filter plate, thus achieving the purpose of self-cleaning. This eliminates the need for frequent disassembly and cleaning by personnel, reducing the workload and improving the working efficiency of the equipment. In this invention, dust and impurities on the filter plate are scraped by a second scraper, causing the dust to fall into the lower part of the filter body and concentrate in a conical groove. From there, it enters the connecting pipe and then the discharge pipe. Meanwhile, dust on the first dust screen in the pretreatment area is scraped by the first scraper and falls above the V-shaped collection trough at the bottom of the air inlet hood. Dust scraped by the second scraper enters the V-shaped collection trough through the discharge pipe and connecting holes. Prolonged dust flow can lead to dust accumulation in the discharge pipe. At this point, the exhaust fan in the mounting slot is activated, rapidly reducing the pressure inside the V-shaped collection trough. This process forces the dust accumulated in the discharge pipe into the V-shaped collection trough. Simultaneously, due to the pressure difference between the inside and outside, the baffle is squeezed open, thereby opening the feed trough. This allows all the dust scraped off by the first scraper to fall into the V-shaped collection trough, concentrating all the dust for easy collection and processing later. After the dust collection is complete, the exhaust fan is turned off, and the baffle returns to its original position under the action of the torsion spring, allowing it to continue to collect dust above. The collected dust is sealed in the V-shaped collection trough, preventing it from floating in the filter and clogging the equipment due to subsequent airflow, thus reducing the impact on the equipment's lifespan.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, 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] This invention provides, for example Figure 1 - Figure 11 The V-type high-efficiency explosion-proof filter with dust suppression function is shown, including filter body 1, air inlet hood 2 and protective cover 3. The filter body hood 2 is characterized by having a dust removal mechanism 4 and a dust collection assembly 7 distributed on the upper end of the air inlet hood 2, with the air inlet hood 2 installed on the front of the filter body 1 and the protective cover 3 fitted on the outside of the filter body 1. The dust removal mechanism 4 includes electric cylinders 401 installed at the lower edges of both sides of the outer wall of the air intake hood 2. Each electric cylinder 401 has a push shaft 402 inserted into its output end. A first connecting frame 403 is fixedly installed between one end of each push shaft 402. First connecting rods 404 are fixedly installed at both ends of the bottom of the first connecting frame 403. One end of each first connecting rod 404 passes through the inner wall of both ends of the air intake hood 2 and is fixedly connected to a first scraper 405. Multiple second connecting frames 406 are fixedly installed at equal intervals on one side of the first connecting frame 403. Each second connecting frame 406 has a second connecting rod 407 fixedly installed at its bottom. One end of each second connecting rod 407 passes through the inner wall of the protective cover 3 and the inner wall of the filter body 1 and is fixedly connected to a second scraper 408. A connecting pipe 409 is inserted and installed on one side of the protective cover 3. A pressure sensor 410 is inserted and installed on the top of the connecting pipe 409. Wires 411 are inserted and connected on both sides of the pressure sensor 410. The two electric cylinders 401 are electrically connected to the pressure sensor 410 through the two wires 411 respectively. In use, since the filter body 1 is installed inside the protective cover 3, and its front air intake area is connected to the air intake hood 2, the airflow from the area is guided into the protective cover 3 through the air intake hood 2, where it is filtered by the filter body 1. The filtered airflow is then guided to other areas for further processing through the connecting pipe 409. During the airflow filtration process, after the airflow enters the air intake hood 2, it first passes through the first dustproof mesh 5 between the air intake hood 2 and the filter body 1 to intercept dust, and a large amount of dust adheres to the first dustproof mesh 5. Then, the pre-treated airflow enters the interior of the filter body 1. The internal shape of the V-shaped filter is as shown in the instruction manual. Figure 5 Included with instruction manual Figure 6As shown, the airflow areas are all V-shaped, allowing the airflow to come into contact with the filter plate 6 inside the filter body 1. The filter plate 6 then filters out the remaining small dust particles, which are then discharged through the connecting pipe 409. However, over time, the dust and impurities adhering to the first dust screen 5 and the upper part of the filter plate 6 accumulate, reducing the flow at the air inlet area and increasing the pressure in the exhaust area at the rear end of the connecting pipe 409. When the pressure increases, the pressure sensor 410 installed on the connecting pipe 409 can sense the pressure. The pressure is increased, triggering the system. Once triggered, the electric cylinders 401 on both sides of the air intake hood 2 are activated to retract the push shaft 402, causing it to lower the first connecting frame 403 and the second connecting frame 406. Then, driven by the first connecting rod 404 and the second connecting rod 407, the first scraper 405 and the second scraper 408 move up and down synchronously within the air intake hood 2 and the filter body 1, thereby scraping off the dust and impurities attached to the first dustproof net 5 and the filter plate 6. This achieves the purpose of self-cleaning, eliminating the need for frequent disassembly of the equipment by staff, reducing workload, and improving the working efficiency of the equipment.

[0019] Each second connecting rod 407 has a pressure sensor 412 slidably connected to its outer wall. Each pressure sensor 412 has a spring 413 fixedly installed at its bottom. The bottom of each spring 413 is fixedly connected to the top of the protective cover 3. Each pressure sensor 412 is electrically connected to two electric cylinders 401. During the dust removal process of the first scraper 405 and the second scraper 408, when the first connecting frame 403 lowers the second connecting frame 406 to a certain extent, the second connecting frame 406 will squeeze the pressure sensor 412 below, thereby triggering the electric cylinder 401 again to control the electric cylinder 401 to extend the push shaft 402 and reset the first scraper 405 and the second scraper 408, etc., for the next dust removal. At the same time, during the process of squeezing the pressure sensor 412, it will compress the spring 413 to achieve buffering and prevent excessive squeezing from damaging the pressure sensor 412. Furthermore, a first dustproof net 5 is installed between the inner wall of the filter body 1 and the inner wall of the air intake hood 2, and one side of the first scraper 405 contacts one side of the first dustproof net 5. Multiple filter plates 6 are installed at equal intervals in a V-shape on the inner wall of one end of the filter body 1, and the outer wall of each second scraper 408 contacts one side of each filter plate 6. The particle size of the filter particles of the filter plate 6 is smaller than that of the first dustproof net 5, which facilitates secondary filtration to intercept finer dust. Furthermore, the dust collection assembly 7 includes multiple conical grooves 701 evenly spaced on the bottom of the inner wall of the filter body 1, multiple discharge pipes 702 evenly spaced on the bottom of the protective cover 3, a V-shaped collection trough 703 installed on the bottom of the air inlet cover 2, and multiple connecting pipes 704 evenly spaced on the bottom of the inner wall of the protective cover 3. The inner walls at both ends of each connecting pipe 704 are connected to the inner walls of each conical groove 701 and each discharge pipe 702, respectively. The dust and impurities on the filter plate 6 are scraped by the second scraper 408, causing the dust to fall into the lower part of the filter body 1 and then into the conical grooves 701. The dust then enters the connecting pipes 704 through the conical grooves 701 and then into the discharge pipes 702 through the connecting pipes 704.

[0020] The top of the V-shaped material collection trough 703 is provided with multiple feed troughs 705 at equal intervals. Each feed trough 705 has a baffle 706 rotatably connected to one side of its inner wall. Each baffle 706 has a torsion spring 707 fixedly connected to the outer wall at both ends. Each torsion spring 707 is fixedly connected to the inner wall at both ends of the V-shaped material collection trough 703. The dust on the first dustproof net 5 in the pretreatment area is scraped off by the first scraper 405 and falls onto the V-shaped material collection trough 703 at the bottom of the air intake hood 2.

[0021] A mounting groove 708 is provided on one side of the outer wall of the V-shaped collecting trough 703. An exhaust fan 709 is installed on the inner wall of the mounting groove 708. A second dustproof net 710 is installed at the edge of one side of the inner wall of the mounting groove 708. Multiple connecting holes 711 are equidistantly provided on the other side of the outer wall of the V-shaped collecting trough 703. The inner wall of the other end of each discharge pipe 702 is connected to the inner wall of each connecting hole 711. Dust scraped off by the second scraper 408 enters the interior of the V-shaped collecting trough 703 through the discharge pipe 702 and the connecting holes 711. Prolonged dust flow causes dust to accumulate in the discharge pipe 702. At this time, activating the exhaust fan 709 in the mounting groove 708 rapidly reduces the pressure inside the V-shaped collecting trough 703, thereby... The dust accumulated in the discharge pipe 702 is pressed into the V-shaped collection trough 703. At the same time, due to the pressure difference between the inside and outside, the baffle 706 is squeezed open, which in turn opens the feed trough 705, so that all the dust scraped off by the first scraper 405 falls into the V-shaped collection trough 703. This ensures that all the dust is concentrated in the V-shaped collection trough 703, which facilitates unified processing and collection later. After the dust is collected, the exhaust fan 709 is turned off, and the baffle 706 returns to its original position under the action of the torsion spring 707. It can continue to carry dust above and seal the collected dust in the V-shaped collection trough 703. This prevents the dust from floating in the filter and causing equipment blockage due to subsequent airflow, thus reducing the impact on the equipment's lifespan.

[0022] A protective plate 712 is hinged to one side of the bottom of the V-shaped collection trough 703. A handle 713 is fixedly installed on the edge of one side of the bottom of the protective plate 712. A limiting strip 714 is rotatably connected to one side of the bottom of the V-shaped collection trough 703, and one side of the limiting strip 714 contacts one side of the protective plate 712. After the dust is collected, the baffle 706 returns to its original position. By rotating the limiting strip 714 at the bottom of the V-shaped collection trough 703, the limiting of the protective plate 712 is released. After opening it with the handle 713, the dust can be discharged and collected from the bottom of the V-shaped collection trough 703. It is very convenient to operate.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
