Description

Technical Field

[0001] This invention relates to the field of oil fume filtration technology, specifically to an electrostatic oil fume purification and filtration device. Background Technology

[0002] In modern kitchens and industrial production, fume purification is a crucial environmental issue. Traditional fume purification technologies primarily include physical filtration and chemical decomposition methods. Physical filtration typically uses materials such as filter screens or activated carbon, which can effectively remove particulate matter from fumes, but it struggles to handle fumes containing esters and other organic compounds, resulting in limited purification effectiveness. Chemical decomposition requires specific chemical reagents to break down oily substances; while offering higher purification efficiency, it also carries the risk of secondary pollution to human health and the environment. Furthermore, both methods require regular filter replacement or cleaning of chemical reagents, leading to high maintenance costs, and the cleaning and replacement of equipment are also cumbersome.

[0003] With the development of technology, electrostatic technology has been introduced into oil fume purification systems, forming electrostatic oil fume purification and filtration devices. Electrostatic technology mainly utilizes a high-voltage electric field to generate an electrostatic field. Oil fume particles are attracted by charges when passing through the electric field, and the charge collection plate can be periodically cleaned, thus achieving continuous and efficient oil fume purification. However, in existing electrostatic oil fume purification devices, the stability of the charges and collection efficiency decrease significantly under high-temperature environments, seriously affecting the purification efficiency of the oil fumes.

[0004] Therefore, the present invention proposes an electrostatic oil fume purification and filtration device to make up for and improve the deficiencies of the prior art. Summary of the Invention

A second spring is also fixedly connected in the side cavity of the movable frame. A stop pawl is also rotatably connected to the top of the box and engages with the ratchet.

[0012] Furthermore, the rotating mechanism also includes a connecting rod fixedly connected to the top of the limiting block, a triangular block fixedly connected to the top of the connecting rod, the inclined surface of the triangular block being slidably connected to the moving frame, a V-shaped elastic plate fixedly connected to the end of the moving frame away from the triangular block, and the end of the elastic plate away from the moving frame being fixedly connected to a protrusion on the top of the box.

[0013] Furthermore, the exhaust mechanism includes a housing fixedly connected to the side of the machine body, a motor fixedly connected to the outside of the housing, a blade fixedly connected to the output end of the motor, a through hole for exhaust gas discharge on the top of the housing, a drive shaft fixedly connected to the output end of the motor, and the drive shaft extending into the machine body, with a second cam fixedly connected to the end of the drive shaft away from the motor.

[0015] Furthermore, the cleaning mechanism also includes a slide rod that is horizontally slidably connected to the side of the machine body. One end of the slide rod is fixedly connected to a second roller, which is rotatably connected to a second cam. The other end of the slide rod is rotatably connected to a lever, the middle of which is rotatably connected to a protrusion on the outside of the housing.

[0017] Beneficial effects:

[0018] 1. This device is equipped with a cooling mechanism. Before being electrostatically treated, the oil fumes are cooled by the cooling pipe. After cooling, the temperature of the oil fumes decreases, which helps to enhance the stability of the electrostatic field and the charge adsorption capacity, thereby improving the overall efficiency of oil fume purification. At the same time, the volume of the oil fumes shrinks after cooling, and the airflow becomes more stable, which is conducive to improving the stability and consistency of the purification process.

[0019] 2. This device is equipped with a swing mechanism. When blowing air onto the cooling pipe, the swinging rotating plate expands the air blowing range. The swinging air blowing can increase the turbulence of the airflow, break the boundary layer, and improve the heat transfer coefficient between the air and the cooling pipe, thereby accelerating the heat dissipation rate and improving the cooling effect of high-temperature oil fumes.

[0020] 3. This device is equipped with a rotating mechanism. When cooling high-temperature oil fumes, the cooling tube rotates horizontally, which can spray water mist onto the fin surface. On the one hand, the water mist can be sprayed more evenly on the entire fin surface, improving the evaporative cooling effect of the cooling tube. On the other hand, the water mist can wash away the dust attached to the fin surface, further improving the heat dissipation effect of the cooling tube.

[0021] 4. This device is equipped with a cleaning mechanism. When the rotating rod rotates, it drives the chain to rotate synchronously. The rotating chain continuously taps the surface of the electrostatic precipitator, causing the electrostatic precipitator to shake continuously. When the electrostatic precipitator shakes, the oil fume particles attached to the surface of the electrostatic precipitator are shaken off into the machine body, reducing the clogging of the electrostatic precipitator. This ensures that the air intake of the machine body will not decrease significantly due to the clogging of the electrostatic precipitator, thereby ensuring the filtering effect of the electrostatic precipitator on oil fume particles.

[0034] 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to embodiments.

[0036] See Figures 1 to 10 An electrostatic oil fume purification and filtration device according to this embodiment includes a body 10, an electrostatic mesh 90 fixedly connected inside the body 10, a cooling mechanism 20 for reducing the temperature of oil fumes at the top of the body 10, a swing mechanism 30 for expanding the air blowing range inside the cooling mechanism 20, a rotating mechanism 40 for accelerating cooling at the top of the cooling mechanism 20, an air extraction mechanism 50 for accelerating oil fume purification on the side of the body 10, and a cleaning mechanism 60 for removing particles attached to the electrostatic mesh 90 inside the body 10.

[0037] The cooling mechanism 20 includes a housing 201 fixedly connected to the top of the body 10. A cooling pipe 202 is vertically rotatably connected inside the housing 201, and a rotary joint 204 is fixedly connected to the top of the cooling pipe 202. The bottom of the cooling pipe 202 extends into the body 10, and multiple fins 203 for heat dissipation are fixedly connected to the outside of the cooling pipe 202.

[0038] The cooling mechanism 20 also includes a bracket 206 fixedly connected to the side of the box 201. A fan 207 is fixedly connected to the top of the bracket 206. An air outlet 205 is opened on the side of the box 201 opposite to the fan 207. An atomizing spray pipe 208 for spraying water to the outside of the cooling pipe 202 is vertically fixedly connected inside the box 201.

[0039] In actual operation, the fume duct is connected to the top of the rotary joint 204. The high-temperature fume enters the cooling pipe 202. At the same time, the fan 207 blows external airflow onto the fins 203 on the surface of the cooling pipe 202, and the atomizing nozzle 208 sprays external water onto the outside of the cooling pipe 202. When the airflow passes over the surface of the cooling pipe 202 and the fins 203, the water mist carries away the heat, thereby reducing the temperature of the fume. After cooling, the fume temperature drops, which helps to enhance the stability of the electrostatic field and the charge adsorption capacity, thereby improving the overall efficiency of fume purification. At the same time, the volume of the fume shrinks after cooling, and the airflow becomes more stable, which is conducive to improving the stability and consistency of the purification process.

[0040] The swing mechanism 30 includes a rotating plate 301 rotatably connected to the side wall of the housing 201. A lever 302 is fixedly connected to the middle of each rotating plate 301. A vertical rod 303 is also vertically slidably connected to the outside of the housing 201. The vertical rod 303 is rotatably connected to the end of the lever 302 away from the rotating plate 301. A limit block 304 is fixedly connected to the top of the vertical rod 303. A first spring 305 is sleeved on the outside of the vertical rod 303, and the first spring 305 is located between the housing 201 and the limit block 304.

[0041] The swing mechanism 30 also includes a reducer 308 fixedly connected to the extended end of the rotating shaft of the fan 207. The output end of the reducer 308 is fixedly connected to a first cam 307. The outside of the vertical rod 303 is also fixedly connected to a first roller 306. The first roller 306 and the first cam 307 are in rolling connection. The reducer 308 adopts a planetary reduction structure.

[0042] In actual operation, when the fan 207 rotates, the speed is reduced by the reducer 308, thereby driving the first cam 307 to rotate slowly in sync. When the first cam 307 rotates, it drives the vertical rod 303 to move downward through the first roller 306. When the vertical rod 303 moves downward, it drives the rotating plate 301 to rotate upward through the lever 302. When the vertical rod 303 moves downward, it squeezes the first spring 305 through the limit block 304. The first spring 305 then drives the vertical rod 303 to move upward. When the vertical rod 303 moves upward, it drives the rotating plate 301 to rotate downward. By using the up and down movement of the vertical rod 303, the rotating plate 301 swings up and down in sync, expanding the air blowing range. The swinging air blowing can increase the turbulence of the airflow, destroy the boundary layer, and improve the heat transfer coefficient between the air and the cooling pipe 202, thereby accelerating the heat dissipation speed and improving the cooling effect on high-temperature oil fumes.

[0043] The rotating mechanism 40 includes a ratchet 401 fixedly connected to the outside of the cooling tube 202, and the ratchet 401 is located at the top of the box 201. A rectangular moving frame 404 is horizontally slidably connected to the top of the box 201. A pawl 402 is slidably connected in the side cavity of the moving frame 404 and engages with the ratchet 401. A second spring 406 is also fixedly connected in the side cavity of the moving frame 404. A stop pawl 403 is also rotatably connected to the top of the box 201 and engages with the ratchet 401.

[0044] The rotating mechanism 40 also includes a connecting rod 408 fixedly connected to the top of the limiting block 304. A triangular block 407 is fixedly connected to the top of the connecting rod 408. The inclined surface of the triangular block 407 is slidably connected to the moving frame 404. A V-shaped elastic plate 405 is fixedly connected to the end of the moving frame 404 away from the triangular block 407. The end of the elastic plate 405 away from the moving frame 404 is fixedly connected to the top protrusion of the box 201.

[0045] In actual operation, when the vertical rod 303 moves downward, it drives the triangular block 407 to move downward synchronously via the connecting rod 408. The inclined surface of the triangular block 407 pushes the moving frame 404 to move horizontally. When the moving frame 404 moves horizontally, it drives the ratchet 401 to rotate horizontally via the pawl 402. The ratchet 401 drives the cooling tube 202 to rotate at an angle. When the moving frame 404 is horizontal, it pulls the elastic plate 405 to deform. When the vertical rod 303 moves upward, it drives the triangular block 407 to move upward synchronously via the connecting rod 408. At this time, the elastic plate 405 pulls the moving frame 404. When moving horizontally in the opposite direction, the pawl 402 is squeezed by the ratchet 401 and enters the cavity on the side of the moving frame 404. During the reverse movement, the stop pawl 403 restricts the ratchet 401 from rotating in the opposite direction. The cooling tube 202 rotates horizontally, which can spray water mist onto the surface of the fins 203. On the one hand, the water mist can be sprayed more evenly on the entire surface of the fins 203, improving the evaporative cooling effect of the cooling tube 202. On the other hand, the water mist can wash away the dust attached to the surface of the fins 203, further improving the heat dissipation effect of the cooling tube 202.

[0046] The exhaust mechanism 50 includes a housing 501 fixedly connected to the side of the body 10. A motor 503 is fixedly connected to the outside of the housing 501. A blade 502 is fixedly connected to the output end of the motor 503. A through hole for exhaust gas is opened on the top of the housing 501. A drive shaft 504 is also fixedly connected to the output end of the motor 503, and the drive shaft 504 extends into the body 10. A second cam 505 is fixedly connected to the end of the drive shaft 504 away from the motor 503.

[0047] In actual operation, the motor 503 drives the blade 502 to rotate, thereby generating negative pressure in the outer casing 501, which draws the high-temperature oil fumes from the outside into the machine body 10. When the blade 502 rotates, it drives the second cam 505 to rotate synchronously through the transmission shaft 504.

[0048] The cleaning mechanism 60 includes a movable rod 601 that is horizontally slidably connected to the side of the body 10. One end of the movable rod 601 is rotatably connected to a rotating body 602. A chain 603 for striking the electrostatic net 90 is fixedly connected to the side of the rotating body 602. Movable wheels 604 are symmetrically fixedly connected to both ends of the rotating body 602. The movable wheels 604 are in rolling contact with the surface of the electrostatic net 90. A support rod 606 is fixedly connected to the other end of the movable rod 601. A third spring 605 is sleeved on the outside of the movable rod 601 and is located outside the body 10.

[0049] The cleaning mechanism 60 also includes a slide rod 608 that is horizontally slidably connected to the side of the body 10. One end of the slide rod 608 is fixedly connected to a second roller 609, which is rotatably connected to a second cam 505. The other end of the slide rod 608 is rotatably connected to a lever 607. The middle part of the lever 607 is rotatably connected to a protrusion on the outside of the housing 201. The end of the lever 607 away from the slide rod 608 abuts against a support rod 606.

[0050] In actual operation, when the second cam 505 rotates, it pushes the lever 607 to swing via the second roller 609. The lever 607, by pressing the support rod 606, drives the slide rod 608 to move horizontally. As the slide rod 608 moves, it drives the rotating body 602 to move synchronously. As the rotating body 602 moves, it is driven by the moving wheel 604 to rotate along the surface of the electrostatic net 90. The rotating body 602 drives the chain 603 to strike the surface of the electrostatic net 90, knocking off the adsorbed oil fume particles. In the body 10, when the lever 607 moves away from the support rod 606, the third spring 605 drives the slide rod 608 to move in the opposite direction. At the same time, when the slide rod 608 moves, it drives the rotating body 602 to move synchronously. When the rotating body 602 moves, it is driven by the moving wheel 604 to rotate along the surface of the electrostatic mesh 90, reducing the blockage of the electrostatic mesh 90. This ensures that the air intake in the body 10 will not decrease significantly due to the blockage of the electrostatic mesh 90, thereby ensuring the filtering effect of the electrostatic mesh 90 on oil fume particles.

[0051] A scraper 70 is slidably connected to the inner wall of the cooling pipe 202, and the bottom of the scraper 70 extends into the body 10. The bottom of the scraper 70 is fixedly connected to the inside of the body 10. A collection chamber 80 for collecting waste oil is fixedly connected inside the body 10, and the collection chamber 80 is located directly below the cooling pipe 202.

[0052] In actual operation, when the cooling pipe 202 rotates, the oil fumes attached to the inner wall of the cooling pipe 202 are scraped off by the scraper 70, and the scraped oil fumes fall into the collection chamber 80, thereby reducing the oil fumes attached to the inner wall of the cooling pipe 202, so as to improve the cooling effect on high-temperature oil fumes.

[0053] Working principle:

[0054] High-temperature oil fumes are drawn into the cooling mechanism 20 by the extraction mechanism 50 to cool them down. The cooling capacity is further enhanced by the rotation mechanism 40 and the oscillation mechanism 30. After cooling, the oil fumes are adsorbed and treated by the electrostatic net 90. The cleaning mechanism 60 reduces the oil fume particles adhering to the surface of the electrostatic net 90. When the cooling pipe 202 rotates, the oil fumes adhering to the inner wall of the cooling pipe 202 are scraped off by the scraper 70 and fall into the collection chamber 80, thereby reducing the amount of oil fumes adhering to the inner wall of the cooling pipe 202.

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.
