Description

Technical Field

[0001] The present invention relates to the technical field of oil fume filtration, and particularly to an electrostatic oil fume purification and filtration device. Background Art

[0002] In modern kitchens and industrial production, oil fume purification is an important environmental protection issue. Traditional oil fume purification technologies mainly include physical filtration and chemical decomposition methods. Physical filtration usually uses materials such as filter screens or activated carbon, which can effectively remove particulate matter in oil fume, but it is difficult to handle oil fume containing esters and other organic compounds, and the purification effect is limited; chemical decomposition requires the use of specific chemical reagents to decompose oily substances. Although the purification efficiency is relatively high, there is also a risk that the chemical reagents may cause secondary pollution to human health and the environment. In addition, both methods require regular replacement of filter screens or cleaning of chemical reagents, resulting in relatively high maintenance costs, and the cleaning and replacement of equipment are rather troublesome.

[0003] With the development of technology, electrostatic technology has been introduced into the oil fume purification system, forming an electrostatic oil fume purification and filtration device. Electrostatic technology mainly uses a high-voltage electric field to generate an electrostatic field. When oil fume particles pass through the electric field, they will be adsorbed by charges, and the charge collection plate can be periodically cleaned to achieve continuous and efficient oil fume purification. However, in the existing electrostatic oil fume purification devices, the stability of charges and the collection efficiency will be greatly reduced in a high-temperature environment, seriously affecting the oil fume purification efficiency.

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

[0010] Further, the rotating mechanism further includes a connecting rod fixedly connected to the top of the limiting block. A triangular block is fixedly connected to the top of the connecting rod. The inclined surface of the triangular block is slidably connected to the moving frame. An elastic plate in a V shape is fixedly connected to the end of the moving frame away from the triangular block. The end of the elastic plate away from the moving frame is fixedly connected to the protrusion on the top of the box body.

[0011] Further, the air extraction mechanism includes a housing fixedly connected to the side of the machine body. A motor is fixedly connected to the outside of the housing.

[0015] Beneficial effects: 1. By setting a cooling mechanism in this device, before the oil fume is treated by static electricity, the high-temperature oil fume is cooled by the cooling pipe. After cooling, the temperature of the oil fume drops, which helps to enhance the stability of the electrostatic field and the charge adsorption ability, thereby improving the overall efficiency of oil fume purification. At the same time, the volume of the cooled oil fume shrinks and the airflow becomes more stable, which is beneficial to improving the stability and consistency of the purification process.

[0016] 2. By setting a swinging mechanism in this device, when blowing air into the cooling pipe, the rotating plate that swings up and down is used to expand the blowing range. The swinging blowing can increase the turbulence degree 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 speed and enhancing the cooling effect of the high-temperature oil fume.

[0017] 3. By setting a rotating mechanism in this device, when cooling the high-temperature oil fume, the cooling pipe rotates horizontally, and the water mist can be sprayed onto the surface of the fins. On the one hand, the water mist can be sprayed more evenly on the entire surface of the fins, improving the evaporation cooling effect on the cooling pipe. On the other hand, the water mist can wash away the dust attached to the surface of the fins, further improving the heat dissipation effect of the cooling pipe.

[0018] 4. By setting a cleaning mechanism in this device, when the rotating rod rotates, it drives the chain to rotate synchronously. The rotating chain continuously pats the surface of the static electricity net, causing the static electricity net to shake continuously. When the static electricity net shakes, the oil fume particles attached to the surface of the static electricity net are shaken off into the body, reducing the blockage of the static electricity net, thereby ensuring that the air intake volume in the body will not decrease significantly due to the blockage of the static electricity net, and further ensuring the filtering effect of the static electricity net on the oil fume particles.

Detailed implementation manners

[0031] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] The present invention will be further described below with reference to the embodiments.

[0033] Refer to Figures 1 to 10 , a static electricity oil fume purification and filtration treatment device of this embodiment includes a body 10, a static electricity grid 90 is fixedly connected inside the body 10, a cooling mechanism 20 for reducing the temperature of the oil fume is arranged at the top of the body 10, a swinging mechanism 30 for expanding the blowing range is arranged inside the cooling mechanism 20, a rotating mechanism 40 for accelerating the cooling is arranged at the top of the cooling mechanism 20, an air extraction mechanism 50 for accelerating the purification of the oil fume is arranged on the side of the body 10, and a cleaning mechanism 60 for removing the particles attached to the static electricity grid 90 is arranged inside the body 10.

[0034] The cooling mechanism 20 includes a box body 201 fixedly connected to the top of the body 10, a cooling pipe 202 is vertically rotatably connected inside the box body 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 a plurality of fins 203 for heat dissipation are fixedly connected to the outside of the cooling pipe 202.

[0035] The cooling mechanism 20 further includes a bracket 206 fixedly connected to the side of the box body 201. A blower 207 is fixedly connected to the top of the bracket 206. An air outlet 205 is provided on the side of the box body 201 facing the blower 207. Inside the box body 201, a fogging nozzle 208 is vertically and fixedly connected to spray water outside the cooling pipe 202.

[0036] During specific operation, the oil fume duct is connected to the top of the rotary joint 204. High-temperature oil fume enters the cooling pipe 202. At the same time, the blower 207 blows external air flow towards the fins 203 on the surface of the cooling pipe 202. At the same time, the fogging nozzle 208 sprays external water flow outside the cooling pipe 202. When the air flow passes through the surfaces of the cooling pipe 202 and the fins 203, heat is taken away by the water mist at the same time, thereby reducing the temperature of the oil fume. After cooling, the temperature of the oil fume drops, 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 cooled oil fume shrinks and the air flow becomes more stable, which is beneficial to improving the stability and consistency of the purification process.

[0037] The swinging mechanism 30 includes a rotating plate 301 rotatably connected to the side wall of the box body 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 box body 201. The vertical rod 303 is rotatably connected to one end of the lever 302 away from the rotating plate 301. A limiting 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 box body 201 and the limiting block 304.

[0038] The swinging mechanism 30 further includes a reducer 308 fixedly connected to the extended end of the rotating shaft of the blower 207. A first cam 307 is fixedly connected to the output end of the reducer 308. A first roller 306 is also fixedly connected to the outside of the vertical rod 303. The first roller 306 and the first cam 307 are in rolling connection. The reducer 308 adopts a planetary reduction structure.

[0039] During specific operation, when the blower 207 rotates, the speed is reduced by the reducer 308, thereby driving the first cam 307 to rotate slowly synchronously. 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, the first spring 305 is compressed by the limiting block 304, and the first spring 305 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 is driven to swing up and down synchronously, expanding the blowing range. The swinging blowing can increase the turbulence degree of the air flow, break the boundary layer, improve the heat transfer coefficient between the air and the cooling pipe 202, thereby accelerating the heat dissipation speed and enhancing the cooling effect on the high-temperature oil fume.

[0040] The rotating mechanism 40 includes a ratchet wheel 401 fixedly connected to the outside of the cooling pipe 202, and the ratchet wheel 401 is located at the top of the box body 201. A rectangular moving frame 404 is horizontally slidably connected to the top of the box body 201. A pawl 402 is slidably connected to the side cavity of the moving frame 404, and the pawl 402 meshes with the ratchet wheel 401. A second spring 406 is also fixedly connected to the side cavity of the moving frame 404. A stop pawl 403 is also rotatably connected to the top of the box body 201, and the stop pawl 403 meshes with the ratchet wheel 401.

[0041] The rotating mechanism 40 further 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. One end of the moving frame 404 away from the triangular block 407 is fixedly connected with a V-shaped elastic plate 405. One end of the elastic plate 405 away from the moving frame 404 is fixedly connected to the protrusion on the top of the box body 201.

[0042] During specific operation, when the vertical rod 303 moves downward, it drives the triangular block 407 to move downward synchronously through 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 wheel 401 to rotate horizontally through the pawl 402. The ratchet wheel 401 drives the cooling pipe 202 to rotate by 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 through the connecting rod 408. At this time, the elastic plate 405 pulls the moving frame 404 to move horizontally in the reverse direction. During the reverse movement, the pawl 402 is squeezed by the ratchet wheel 401, and the pawl 402 enters the side cavity of the moving frame 404. During the reverse movement, the stop pawl 403 restricts the reverse rotation of the ratchet wheel 401. The cooling pipe 202 rotates horizontally, and the water mist can be sprayed onto the surface of the fin 203. On the one hand, the water mist can be sprayed more evenly on the entire surface of the fin 203, improving the evaporative cooling effect on the cooling pipe 202. On the other hand, the water mist can wash away the dust attached to the surface of the fin 203, further improving the heat dissipation effect of the cooling pipe 202.

[0043] The air extraction mechanism 50 includes a housing 501 fixedly connected to the side of the machine 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 exhausting waste gas is opened at the top of the housing 501. A transmission shaft 504 is also fixedly connected to the output end of the motor 503, and the transmission shaft 504 extends into the machine body 10. A second cam 505 is fixedly connected to one end of the transmission shaft 504 away from the motor 503.

[0044] During specific operation, the motor 503 drives the blade 502 to rotate, thereby generating a negative pressure in the housing 501, sucking the external high-temperature oil fume into the body 10. When the blade 502 rotates, it drives the second cam 505 to rotate synchronously through the transmission shaft 504.

[0045] The cleaning mechanism 60 includes a moving rod 601 horizontally and slidably connected to the side of the body 10. One end of the moving rod 601 is rotatably connected to a rotating body 602. A chain 603 for hitting the static electricity net 90 is fixedly connected to the side of the rotating body 602. Moving wheels 604 are symmetrically and fixedly connected to both ends of the rotating body 602. The moving wheels 604 are in rolling connection with the surface of the static electricity net 90. The other end of the moving rod 601 is fixedly connected to a support rod 606. A third spring 605 is sleeved outside the moving rod 601, and the third spring 605 is located outside the body 10.

[0046] The cleaning mechanism 60 further includes a sliding rod 608 horizontally and slidably connected to the side of the body 10. One end of the sliding rod 608 is fixedly connected to a second roller 609. The second roller 609 is in rolling connection with the second cam 505. The other end of the sliding rod 608 is rotatably connected to a lever 607. The middle of the lever 607 is rotatably connected to the protrusion outside the box body 201. The end of the lever 607 away from the sliding rod 608 abuts against the support rod 606.

[0047] During specific operation, when the second cam 505 rotates, the second cam 505 pushes the lever 607 to swing through the second roller 609. The lever 607 drives the sliding rod 608 to move horizontally by squeezing the support rod 606. When the sliding rod 608 moves, it drives the rotating body 602 to move synchronously. When the rotating body 602 moves, it drives the rotating body 602 to rotate along the surface of the static electricity net 90 through the moving wheels 604. The rotating rotating body 602 drives the chain 603 to hit the surface of the static electricity net 90, knocking the adsorbed oil fume particles into the body 10. When the lever 607 is away from the support rod 606, the third spring 605 drives the sliding rod 608 to move in the reverse direction. At the same time, when the sliding rod 608 moves, it drives the rotating body 602 to move synchronously. When the rotating body 602 moves, it drives the rotating body 602 to rotate along the surface of the static electricity net 90 through the moving wheels 604, reducing the blockage of the static electricity net 90, thereby ensuring that the air intake volume in the body 10 will not drop significantly due to the blockage of the static electricity net 90, and further ensuring the filtering effect of the static electricity net 90 on the oil fume particles.

[0048] 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 bin 80 for collecting waste oil is fixedly connected to the inside of the body 10, and the collection bin 80 is located directly below the cooling pipe 202.

[0049] During specific operation, when the cooling pipe 202 rotates, the oil fume adhering to the inner wall of the cooling pipe 202 is scraped off by the scraper 70, and the scraped oil fume falls into the collection bin 80, thereby reducing the oil fume adhering to the inner wall of the cooling pipe 202, so as to improve the cooling effect on the high-temperature oil fume.

[0050] Working principle: The external high-temperature oil fume is sucked into the cooling mechanism 20 by the air extraction mechanism 50 to cool the high-temperature oil fume. At the same time, the cooling capacity of the high-temperature oil fume is improved through the rotation mechanism 40 and the swing mechanism 30. Then, the cooled oil fume is adsorbed and treated by the static electricity net 90. At the same time, the cleaning mechanism 60 is used to reduce the oil fume particles adhering to the surface of the static electricity net 90. When the cooling pipe 202 rotates, the oil fume adhering to the inner wall of the cooling pipe 202 is scraped off by the scraper 70, and the scraped oil fume falls into the collection bin 80, thereby reducing the oil fume adhering to the inner wall of the cooling pipe 202.
