Description

Technical Field

[0001] This utility model relates to the technical field of exhaust gas filtration-type oil fume purifiers, and in particular to an exhaust gas filtration-type oil fume purifier. Background Technology

[0002] With rapid industrialization and urbanization, air quality has become a major public concern. Among various sources of air pollution, cooking fumes from the catering industry and household kitchens account for a significant proportion, drawing widespread environmental attention. Traditional methods of treating cooking fumes, such as simple mechanical filtration, can only remove larger particles of fumes, proving ineffective against fine particles and harmful gases. While electrostatic adsorption purifiers offer good purification results, they suffer from high energy consumption, are prone to ozone pollution, and have high maintenance costs.

[0003] The applicant discovered through a search that a Chinese patent, "A Filter-Type Oil Fume Purifier," with publication (announcement) number "CN 214009325 U," primarily utilizes inlet and outlet pipes to provide ventilation within the protective enclosure, thereby aiding in heat dissipation for the motor inside, preventing overheating damage, and extending the motor's lifespan. However, this patent fails to deliver the filtered oil fumes to the interior of the exhaust pipe and expel them via a centrifugal exhaust fan. Consequently, in actual use, oil fumes may accumulate and fill various corners within the enclosure. Due to the lack of effective exhaust path constraints, the oil fumes are difficult to expel in an orderly manner, potentially leading to incomplete emission. This negatively impacts the normal operation and lifespan of the equipment. Therefore, we propose an exhaust gas filter-type oil fume purifier. Utility Model Content

[0004] The purpose of this utility model is to provide a waste gas filtration-type oil fume purifier to solve the problem mentioned in the background art that the filtered oil fumes cannot be transported to the interior of the exhaust pipe and discharged by a centrifugal exhaust fan. In actual use, oil fumes may fill and gradually accumulate in various corners inside the box. Due to the lack of effective constraints on the emission path, the oil fumes are difficult to discharge in an orderly manner, which may lead to incomplete emission. This will have a negative impact on the normal operation and service life of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas filtration type oil fume purifier, including a housing, an air inlet on the front of the housing, a filter assembly inside the housing, the filter assembly including a metal grid plate, a fiber pad plate, an activated carbon plate, an exhaust pipe and an exhaust filter plate, three sets of sliding grooves on the inner wall of the housing, sliders fixedly connected to the outer walls of the metal grid plate, fiber pad plate and activated carbon plate, the three sets of sliders being slidably connected to the inner walls of the three sets of sliding grooves, an exhaust fan connected to the housing via a connecting plate, and a centrifugal exhaust fan connected to the exhaust pipe via a fixed plate.

[0006] As a preferred embodiment, the connecting plate is fixedly connected to the inner wall of the housing, and multiple sets of exhaust fans are provided. All sets of exhaust fans are fixedly installed on the outer wall of the connecting plate, and air inlets are provided on the outer wall of the connecting plate.

[0007] As a preferred embodiment, the outer wall of the exhaust pipe is fixedly connected to the inner wall of the housing, the front end of the exhaust pipe is fixedly connected to the back of the connecting plate, and the rear end of the exhaust pipe is fixedly connected to the bottom of the fixing plate.

[0008] As a preferred embodiment, the centrifugal exhaust fan is provided in multiple sets, and all sets of the centrifugal exhaust fan are fixedly installed at the bottom of the fixed plate. The top of the fixed plate is provided with an exhaust hole, and the exhaust filter plate is fixedly connected to the top inner wall of the box.

[0009] As a preferred embodiment, the front of the box is provided with a scraping component, which includes a fixing rod. There are two sets of fixing rods, which are respectively fixedly installed on the left and right outer walls of the box. A sliding plate is slidably connected to the outer wall of each set of fixing rods.

[0010] As a preferred embodiment, scrapers are fixedly connected to one side of the two sets of sliding discs, a gripping block is fixedly connected to the outer wall of the left sliding disc, a spring is fixedly connected to the bottom of the left sliding disc, the lower end of the spring is fixedly connected to the bottom of the left fixing rod, a fixing frame is fixedly connected to the lower front of the box, and a sealing block is inserted into the outer right side of the fixing frame.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. Through the set filter components, after the oil fumes enter the cabinet through the air inlet, they first pass through the metal grid plate, fiber pad plate and activated carbon plate in sequence for triple filtration. In this process, the metal grid plate intercepts larger oil fumes and impurities, the fiber pad plate further filters fine particles, and the activated carbon plate adsorbs harmful gases and odor molecules in the oil fumes. The filtered oil fumes are then transported to the exhaust pipe by the exhaust fan. The exhaust pipe provides a directional transport channel for the oil fumes, effectively preventing the oil fumes from moving around disorderly inside the cabinet. Then, the centrifugal exhaust fan pushes the oil fumes to the exhaust filter plate, which performs the final fine filtration of the oil fumes to ensure that the exhaust gas is as clean as possible.

[0013] 2. With the included scraping component, users can manually hold the handle and move it downwards during equipment maintenance. Under the action of the sliding plate and the fixed rod, the scraper will adhere tightly to the surface of the air inlet, scraping off the oil stains attached to it and allowing them to fall into the fixed frame. After the oil stain removal is completed, the scraper will automatically return to its initial position under the action of the spring, preparing for the next cleaning. Staff can periodically open the sealing block to clean the oil stains accumulated inside the fixed frame, ensuring that the equipment is always in a highly efficient operating state and maintaining good purification performance.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see the appendix Figure 1 - Appendix Figure 4 A waste gas filtration-type oil fume purifier includes a housing 1 with an air inlet 2 on the front. A filter assembly 3 is installed inside the housing 1, comprising a metal grille 302, a fiber pad 303, an activated carbon plate 304, an exhaust pipe 309, and an exhaust filter plate 313. Three sets of sliding grooves 301 are provided on the inner wall of the housing 1. Sliding blocks 305 are fixedly connected to the outer walls of the metal grille 302, fiber pad 303, and activated carbon plate 304. The three sets of sliding blocks 305 are slidably connected to the inner walls of the three sets of sliding grooves 301. A fan 308 is connected to the housing 1 via a connecting plate 306, and a centrifugal exhaust fan 312 is connected to the exhaust pipe 309 via a fixing plate 310. The connecting plate 306 is fixedly connected to the inner wall of the housing 1. Multiple sets of exhaust fans 308 are provided, and all sets of exhaust fans 308 are fixedly installed on the outer wall of the connecting plate 306. An air inlet 307 is provided on the outer wall of the connecting plate 306. The outer wall of the exhaust pipe 309 is fixedly connected to the inner wall of the housing 1. The front end of the exhaust pipe 309 is fixedly connected to the back of the connecting plate 306, and the rear end of the exhaust pipe 309 is fixedly connected to the bottom of the fixing plate 310. Multiple sets of centrifugal exhaust fans 312 are provided, and all sets of centrifugal exhaust fans 312 are fixedly installed on the bottom of the fixing plate 310. An exhaust hole 311 is provided on the top of the fixing plate 310. An exhaust filter plate 313 is fixedly connected to the top inner wall of the housing 1.

[0024] The tops of the metal grating 302, fiber pad 303, and activated carbon plate 304 are all fixedly connected with pulls. This design greatly facilitates users to remove them from inside the housing 1 for easy maintenance and replacement. The air inlet 307 is precisely aligned with the front end of the exhaust pipe 309, while the exhaust outlet 311 is directly opposite the rear end of the exhaust pipe 309, ensuring that exhaust gas can enter and exit smoothly.

[0025] Specifically, through the filter assembly 3, the oil fumes enter the housing 1 through the air inlet 307 and pass through the metal grille 302, fiber pad 303, and activated carbon plate 304 for triple filtration. The metal grille 302 intercepts larger oil fumes and impurities, the fiber pad 303 filters fine particles, and the activated carbon plate 304 adsorbs harmful gases and odor molecules. The filtered oil fumes are then transported to the exhaust pipe 309 by the exhaust fan 308. The exhaust pipe 309 guides the oil fumes to flow in a specific direction, preventing them from wandering around randomly in the housing 1. Subsequently, the centrifugal exhaust fan 312 pushes the oil fumes to the exhaust filter plate 313, where the exhaust filter plate 313 performs a final fine filtration to ensure that the exhaust gas is clean.

[0026] Example 2:

[0027] Please see the appendix Figure 1 Appendix Figure 5 and appendix Figure 6 Furthermore, based on Embodiment 1, the front of the box 1 is provided with a scraping component 4, which includes a fixing rod 401. Two sets of fixing rods 401 are provided, and the two sets of fixing rods 401 are respectively fixedly installed on the left and right outer walls of the box 1. Sliding discs 402 are slidably connected to the outer walls of the two sets of fixing rods 401. Scrapers 403 are fixedly connected to the corresponding side of the two sets of sliding discs 402. A gripping block 404 is fixedly connected to the outer wall of the left sliding disc 402. A spring 405 is fixedly connected to the bottom of the left sliding disc 402. The lower end of the spring 405 is fixedly connected to the bottom of the left fixing rod 401. A fixing frame 406 is fixedly connected to the lower part of the front of the box 1. A sealing block 407 is inserted into the right outer wall of the fixing frame 406.

[0028] On the right outer wall of the fixed frame 406, a sealing hole adapted to the sealing block 407 is opened. The inner bottom wall of the fixed frame 406 is designed to tilt to the right. When unclean oil stains accumulate inside, under the action of gravity, the oil stains will naturally flow along the tilted bottom wall to the sealing hole, thereby achieving automatic discharge and ensuring the cleanliness of the inside of the fixed frame 406.

[0029] Specifically, through the scraping component 4, when performing equipment maintenance, the user can manually hold the grip 404 and move it downwards. Then, under the action of the sliding plate 402 and the fixed rod 401, the scraper 403 will stick to the surface of the air inlet 2 and scrape off the oil stains attached thereto, allowing them to fall into the fixed frame 406. After the oil stain removal work is completed, under the action of the spring 405, the scraper 403 will automatically move back to the initial position, preparing for the next cleaning. The staff can periodically open the sealing block 407 to clean the oil stains accumulated inside the fixed frame 406, ensuring that the equipment is always in a high-efficiency operating state and ensuring good purification performance.

[0030] Working principle of this utility model: This utility model is a waste gas filtration type oil fume purifier. First, the oil fumes generated in the kitchen enter the purifier through the air inlet 2 on the front of the housing 1. The oil fumes entering the housing 1 first encounter the metal grid plate 302, which blocks larger oil fume particles and impurities, completing the primary filtration. The oil fumes filtered by the metal grid plate 302 continue to move forward and reach the fiber pad 303. The fiber pad 303 further filters out fine particles in the oil fumes. The oil fumes that have completed the intermediate filtration then come into contact with the activated carbon plate 304, which adsorbs harmful gases and odor molecules in the oil fumes, thus deeply purifying the oil fumes. After undergoing triple filtration, the oil fumes are drawn in by multiple sets of exhaust fans 308 mounted on the connecting plate 306. The connecting plate 306 has air inlets 307 through which the purified oil fumes enter the exhaust duct 309. One end of the exhaust duct 309 is connected to the connecting plate 306, and the other end is connected to the fixing plate 310. Its function is to guide the fumes in a directional flow, preventing them from moving haphazardly within the housing 1. Multiple sets of centrifugal exhaust fans 312 mounted at the bottom of the fixing plate 310 push the oil fumes from the exhaust duct 309 to the exhaust filter plate 313. The exhaust filter plate 313 is fixedly connected to the inner top wall of the housing 1, providing a final fine filtration for the oil fumes, ensuring the quality of the discharged fumes. After the gas is purified as much as possible, it is discharged from the housing 1 into the external environment. Then, when it is necessary to clean and maintain the oil stains on the surface of the air inlet 2, the user manually holds the grip block 404 set on the outer wall of the left sliding plate 402 and moves it downward. As the grip block 404 drives the left sliding plate 402 to slide downward along the left fixed rod 401, the right sliding plate 402 slides simultaneously on the right fixed rod 401. The scraper 403 connected between the two sets of sliding plates 402 will be in close contact with the surface of the air inlet 2. Under the action of the sliding plate 402 and the fixed rod 401, the scraper 403 scrapes off the oil stains attached to the surface of the air inlet 2. The scraped oil stains fall into the fixed frame 406 fixedly connected to the lower front of the housing 1. After the oil stain removal work is completed, the spring 405 connected between the bottom of the left sliding plate 402 and the bottom of the left fixed rod 401 plays an elastic reset role, driving the left sliding plate 402 to move upward, thereby causing the scraper 403 to automatically move back to the initial position, preparing for the next cleaning. The right outer wall of the fixed frame 406 is provided with a sealing hole that matches the sealing block 407, and its inner bottom wall is designed to be inclined to the right. When the scraped oil stains accumulate inside the fixed frame 406, under the action of gravity, the oil stains will naturally flow along the inclined bottom wall to the sealing hole. The staff can open the sealing block 407 periodically to drain the oil stains, thereby ensuring the cleanliness of the inside of the fixed frame 406.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
