Description

Technical Field

[0001] This invention relates to the field of oil mist filtration technology, and in particular to a honeycomb filter for separating oil mist in kitchen fumes. Background Technology

[0002] Honeycomb filters are porous filtration devices widely used in kitchen fume purification. Their core consists of multiple regularly arranged honeycomb channels, typically made of metal (such as aluminum), ceramic, or polymer materials, formed through molding, stretching, and other processes. Each honeycomb channel is hexagonal, interconnected to form a continuous airflow channel. The surface can be loaded with activated carbon, fiber felt, or nano-coatings to enhance oil mist adsorption. This structure achieves efficient interception of particulate matter and volatile organic compounds in kitchen fumes by increasing the specific surface area, while simultaneously guiding airflow evenly through the channels. It is widely used in range hoods, industrial waste gas treatment equipment, and other applications.

[0003] Currently, existing honeycomb filters used for oil mist separation in kitchen fumes typically employ a tight-fitting assembly method between the honeycomb filter and the intermediate vapor-liquid filter to ensure filtration efficiency. However, this tight-fitting design has significant shortcomings in practical use: after prolonged use, a large amount of sludge and oil stains accumulate on the contact surfaces of the honeycomb filter and the intermediate vapor-liquid filter, as well as on the surface of the intermediate vapor-liquid filter. Regular disassembly and cleaning are necessary to maintain filtration performance. However, due to the tight contact, there is insufficient space for cleaning, making it difficult to thoroughly clean the inner surface of the honeycomb filter and the intermediate vapor-liquid filter. This easily leads to oil residue, affecting cleaning effectiveness and subsequent filtration efficiency. Furthermore, the inconvenience of cleaning increases the user's maintenance workload and difficulty. Long-term oil residue also accelerates filter aging and damage, shortening its lifespan. Therefore, it fails to meet users' needs for convenient maintenance and efficient cleaning of the filter. Thus, further improvements are necessary.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a honeycomb filter for separating oil mist in kitchen fumes, in order to achieve a more practical purpose. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problems of difficult cleaning and oil residue caused by the tight bonding between the honeycomb filter and the intermediate gas-liquid filter in existing honeycomb filters.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A honeycomb filter for separating oil mist in kitchen fumes includes a housing, a filter mechanism disposed inside the housing for separating and filtering oil mist in the fumes, an adjustment component disposed on one side of the filter mechanism, and a cleaning self-vibration mechanism disposed inside the housing and above the filter mechanism. A fixed frame is fixedly installed inside the housing. The filtration mechanism includes a vapor-liquid filter screen fixedly installed on the fixed frame. Honeycomb components are provided on both the front and rear sides of the vapor-liquid filter screen. An elastic corrugated rubber ring is fixedly connected between the side of the honeycomb component away from the vapor-liquid filter screen and the housing. The cleaning self-vibration mechanism includes a fixed shell, and a cleaning component and a self-vibration component are provided inside the fixed shell. The self-vibration component is located at both ends of the cleaning component. By passing cleaning water into the cleaning component to rinse the gas-liquid filter screen, the cleaning component can drive the self-vibration component to intermittently knock and vibrate the gas-liquid filter screen.

[0007] As a further description of the above technical solution: The honeycomb assembly includes a filter frame, with a plurality of honeycomb filters rotatably connected to the inner side of the filter frame. One end of each honeycomb filter is fixedly provided with an adjustment shaft, and one end of the adjustment shaft passes through the filter frame and extends to the outside of the filter frame.

[0008] As a further description of the above technical solution: The adjustment assembly includes a mounting bracket fixed to the outside of the filter frame, and an adjustment motor is fixedly mounted on the mounting bracket; The adjustment assembly also includes several adjustment gears fixedly sleeved on the adjustment shaft, and the output end of the adjustment motor is fixedly connected to one of the adjustment gears.

[0009] As a further description of the above technical solution: An adjusting rack is fixedly provided on the inner wall of the housing, and the lower end of the adjusting rack meshes with an adjusting gear.

[0010] As a further description of the above technical solution: The housing is also provided with a limiting guide assembly, which includes a limiting slide rail fixed to the inner wall of the housing, a limiting slider slidably connected on the limiting slide rail, and the side of the limiting slider away from the limiting slide rail is fixedly connected to the filter frame.

[0011] As a further description of the above technical solution: The cleaning assembly includes a cleaning cylinder fixed inside a fixed housing. A uniform turntable is rotatably connected inside the cleaning cylinder. A water inlet is provided at the upper part of the cleaning cylinder, and a water outlet is provided at the lower part of the cleaning cylinder.

[0012] As a further description of the above technical solution: The cleaning assembly also includes a sealing baffle that is slidably mounted on the fixed housing. The sealing baffle is correspondingly positioned at the water outlet, and one side of the sealing baffle is fixedly connected to the filter frame.

[0013] As a further description of the above technical solution: The self-vibrating component includes a vibrating sleeve fixed inside the fixed shell. A movable shaft is rotatably connected inside the vibrating sleeve. A linkage turntable is fixedly installed on the movable shaft. A movable pull rod is rotatably connected to the linkage turntable. One end of the movable shaft extends through the vibrating sleeve into the cleaning cylinder and is fixedly connected to the uniform rotating disk.

[0014] As a further description of the above technical solution: The self-vibrating assembly also includes a vibrating element slidably installed on the lower part of the vibrating sleeve, and a movable rod is fixedly provided on the vibrating element. The lower end of the movable rod is rotatably connected to the movable rod.

[0015] As a further description of the above technical solution: A through hole is fixedly opened at the bottom of the housing.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This honeycomb filter screen, used for separating oil mist in kitchen fumes, works in tandem with a cleaning cylinder and a rotating disk. The rotating disk ensures that cleaning water is evenly and stably discharged from the outlet, thoroughly rinsing the vapor-liquid filter screen below. This design allows for even water distribution, ensuring all parts of the vapor-liquid filter screen are thoroughly rinsed, preventing oil residue in some areas due to uneven cleaning and further improving cleaning effectiveness. Simultaneously, the rotating disk drives the movable shaft and vibrating components, causing the vibrating components to intermittently strike the vapor-liquid filter screen, generating high-frequency vibration. This high-frequency vibration, combined with water rinsing, creates a synergistic effect of vibration and washing, causing oil sludge adhering to the vapor-liquid filter screen and honeycomb filter screen to loosen and fall off under the vibration. Combined with water rinsing, this effectively removes stubborn oil sludge, preventing oil sludge adhesion and ensuring thorough cleaning of the filter screen. Furthermore, the high-frequency vibration effectively prevents filter screen pore blockage, extending the filter screen's lifespan, reducing the frequency of filter screen replacement, and lowering operating costs.

[0017] 2. This honeycomb filter, used for separating oil mist in kitchen fumes, uses the coordinated action of adjusting the motor, gears, and racks to separate the tightly fitted honeycomb filter from the vapor-liquid filter, creating a cleaning gap. This design effectively solves the problem of traditional structures where the tightly fitted filter leaves no room for operation, making cleaning difficult. Furthermore, the cleaning gap allows cleaning water to fully enter between the filter screens, thoroughly rinsing the vapor-liquid filter and preventing oil residue, significantly improving the thoroughness of cleaning.

[0018] 3. This honeycomb filter, used for separating oil mist in kitchen fumes, rotates synchronously with the adjustment gears, gradually turning the originally vertically arranged honeycomb filter to a horizontal position. The grease accumulated at the edges of the honeycomb filter can naturally fall off under gravity, while also facilitating the direct rinsing of the edges and corners with cleaning water. This effectively solves the problem of oil accumulation at the edges of vertically arranged honeycomb filters, which cannot flow away by itself and easily forms grease clogging. It reduces the adhesion strength of grease, improves the grease cleaning efficiency, ensures the unobstructed flow of honeycomb channels, and reduces the problem of decreased filtration performance caused by grease clogging.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0023] Please see Figures 1 to 12A honeycomb filter for separating oil mist in kitchen fumes includes a housing 10, a filter mechanism 20 disposed inside the housing 10 for separating and filtering oil mist in the fumes, an adjustment component 30 disposed on one side of the filter mechanism 20, and a cleaning self-vibration mechanism 50 disposed inside the housing 10 and above the filter mechanism 20; a fixing frame 11 is fixedly installed inside the housing 10, and the filter mechanism 20 includes a vapor-liquid filter 21 fixedly installed on the fixing frame 11, with the vapor-liquid filter 21 having a front and rear side... A honeycomb component 22 is provided, and an elastic corrugated rubber ring 23 is fixedly connected between the side of the honeycomb component 22 away from the gas-liquid filter screen 21 and the housing 10. The cleaning self-vibration mechanism 50 includes a fixed housing 51, and a cleaning component 52 and a self-vibration component 53 are provided inside the fixed housing 51. The self-vibration component 53 is located at both ends of the cleaning component 52. By passing cleaning water into the cleaning component 52 to rinse the gas-liquid filter screen 21, the cleaning component 52 can drive the self-vibration component 53 to form intermittent knocking vibrations on the gas-liquid filter screen 21.

[0024] Through the coordinated operation of the cleaning cylinder 521 and the uniform rotating disc 524, the uniform rotating disc 524 ensures that the cleaning water is discharged evenly and stably from the outlet 523, and thoroughly rinses the vapor-liquid filter screen 21 below. This design allows the cleaning water to be sprayed evenly, ensuring that all parts of the vapor-liquid filter screen 21 are thoroughly rinsed, avoiding the problem of oil residue in some areas due to uneven cleaning, and further improving the cleaning effect. At the same time, the rotation of the uniform rotating disc 524 drives the movable shaft 532 and the vibrating component 536 to move. This causes the vibrating element 536 to intermittently strike the gas-liquid filter screen 21, generating high-frequency vibration. This high-frequency vibration, combined with water rinsing, forms a synergistic effect of vibration and washing, causing the sludge adhering to the gas-liquid filter screen 21 and the honeycomb filter screen 222 to loosen and fall off under the vibration. Combined with water rinsing, it can effectively remove stubborn sludge, avoid sludge adhesion and residue, and ensure that the filter screen is thoroughly cleaned. At the same time, the high-frequency vibration can also effectively prevent the filter screen pores from clogging, extend the service life of the filter screen, reduce the frequency of filter screen replacement, and reduce the operating cost.

[0025] Please see Figures 6 to 7The honeycomb assembly 22 includes a filter frame 221, with a plurality of honeycomb filter screens 222 rotatably connected to the inner side of the filter frame 221. One end of the honeycomb filter screen 222 is fixedly provided with an adjusting shaft 223, and one end of the adjusting shaft 223 passes through the filter frame 221 and extends to the outer side of the filter frame 221. The adjusting gear 33 is connected to the honeycomb filter screen 222 through the adjusting shaft 223, and then drives the honeycomb filter screen 222 to rotate synchronously through the adjusting shaft 223, so that the originally vertically arranged honeycomb filter screen 222 gradually rotates to a horizontal state. The sludge accumulated at the edges of the honeycomb filter screen 222 can fall off naturally under the action of gravity, and it is easy for the cleaning water to directly rinse the edges and corners, effectively reducing the adhesion strength of the sludge, improving the sludge cleaning efficiency, and ensuring the unobstructed honeycomb channels.

[0026] Please see Figures 5 to 7 The adjustment assembly 30 includes a mounting bracket 31 fixed to the outside of the filter frame 221, on which an adjustment motor 32 is fixedly mounted. The adjustment assembly 30 also includes several adjustment gears 33 fixedly sleeved on the adjustment shaft 223. The output end of the adjustment motor 32 is fixedly connected to one of the adjustment gears 33. By starting the adjustment motor 32, the output end of the adjustment motor 32 drives the adjustment gear 33 to rotate slowly. The adjustment gear 33 meshes with the adjustment rack 12, driving the adjustment gear 33 to move along the adjustment rack 12. When the adjustment gear 33 moves, it drives the filter frame 221 and the honeycomb filter screen 222 to move synchronously. This allows the originally tightly fitted honeycomb filter screen 222 and the gas-liquid filter screen 21 to separate and form a cleaning gap. This setting facilitates the full entry of cleaning water between the filter screens, achieving a thorough rinsing of the gas-liquid filter screen 21, avoiding oil residue, and significantly improving the thoroughness of cleaning.

[0027] Please see Figures 3 to 5 An adjusting rack 12 is fixedly provided on the inner wall of the housing 10. The lower end of the adjusting rack 12 meshes with the adjusting gear 33. By setting the adjusting rack 12, when the adjusting gear 33 meshes with the adjusting rack 12, the adjusting gear 33 is driven to move along the adjusting rack 12. When the adjusting gear 33 moves, it drives the filter frame 221 and the honeycomb filter 222 to move synchronously.

[0028] Please see Figures 3 to 4 The housing 10 is also equipped with a limiting guide assembly 40. The limiting guide assembly 40 includes a limiting slide rail 41 fixed to the inner wall of the housing 10. A limiting slider 42 is slidably connected to the limiting slide rail 41. The side of the limiting slider 42 away from the limiting slide rail 41 is fixedly connected to the filter frame 221. The filter frame 221 drives the limiting slider 42 to slide along the limiting slide rail 41. The cooperation between the limiting slide rail 41 and the limiting slider 42 limits and guides the movement of the filter frame 221, ensuring smooth and reliable movement.

[0029] Please see Figures 8 to 10The cleaning component 52 includes a cleaning cylinder 521 fixed inside the fixed housing 51. A uniform rotating disk 524 is rotatably connected inside the cleaning cylinder 521. A water inlet 522 is provided at the upper part of the cleaning cylinder 521, and a water outlet 523 is provided at the lower part of the cleaning cylinder 521. By injecting cleaning water through the water inlet 522 at the upper part of the cleaning cylinder 521, the cleaning water continuously enters the cleaning cylinder 521 and drives the uniform rotating disk 524 to rotate under the force of the water flow. The uniform rotating disk 524 can make the cleaning water evenly and stably discharged from the water outlet 523 and thoroughly rinse the vapor-liquid filter screen 21 below.

[0030] Please see Figures 9 to 10 The cleaning component 52 also includes a sealing baffle 525 that is slidably mounted on the fixed housing 51. The sealing baffle 525 is correspondingly set at the water outlet 523. One side of the sealing baffle 525 is fixedly connected to the filter frame 221. During the movement of the filter frame 221 and the honeycomb filter 222, since the filter frame 221 is connected to the sealing baffle 525, the filter frame 221 can drive the sealing baffle 525 to move synchronously, so that the sealing baffle 525 releases the blockage of the water outlet 523 of the cleaning cylinder 521, and realizes the automatic opening of the water outlet 523.

[0031] Please see Figures 8 to 12 The self-vibrating component 53 includes a vibrating sleeve 531 fixed inside the fixed shell 51. A movable shaft 532 is rotatably connected inside the vibrating sleeve 531. A linkage turntable 533 is fixedly installed on the movable shaft 532. A movable pull rod 534 is rotatably connected to the linkage turntable 533. One end of the movable shaft 532 extends through the vibrating sleeve 531 into the cleaning cylinder 521 and is fixedly connected to the uniform turntable 524. When the uniform turntable 524 rotates, it drives the movable shaft 532 to rotate synchronously. The movable shaft 532 then drives the linkage turntable 533 to rotate. The linkage turntable 533 then drives the movable connecting rod to perform up-and-down reciprocating motion. The movable connecting rod drives the movable rod 535 and the vibrating component 536 to perform stable reciprocating motion under the limiting and guiding action of the vibrating sleeve 531.

[0032] Please see Figures 11 to 12The self-vibrating assembly 53 also includes a vibrating element 536 slidably installed on the lower part of the vibrating housing 531. A movable rod 535 is fixedly provided on the vibrating element 536, and the lower end of the movable pull rod 534 is rotatably connected to the movable rod 535. The vibrating element 536 is driven by the movable connecting rod to reciprocate stably under the limiting and guiding action of the vibrating housing 531. When the vibrating element 536 moves down, it contacts the gas-liquid filter screen 21 and achieves intermittent knocking, so that the gas-liquid filter screen 21 generates high-frequency vibration while being washed by the cleaning water. This setting can loosen and remove the sludge attached to the gas-liquid filter screen 21 and the honeycomb filter screen 222 under the action of vibration. Combined with the water flow rinsing, it achieves a synergistic effect of vibration and washing, effectively enhancing the cleaning ability of stubborn sludge, avoiding sludge adhesion and residue, ensuring thorough cleaning of the filter screen, and effectively preventing the filter screen pores from clogging and extending the service life of the filter screen.

[0033] Please see Figure 3 A through hole 13 is fixedly provided at the bottom of the housing 10; the through hole 13 at the bottom of the housing 10 facilitates the drainage of cleaning water.

[0034] Working principle: When the oil fume flows through the filtration mechanism 20, the oil fume passes through the honeycomb filter 222 and the middle vapor-liquid filter 21 in sequence. During the process of passing through multiple layers of filters, the oil fume comes into full contact with the honeycomb filter 222 and the vapor-liquid filter 21, realizing multi-stage oil mist separation. The honeycomb filter 222 enables the oil fume to form collision, condensation and turbulence in the honeycomb channels, which initially intercepts and separates large oil droplets and oil mist in the oil fume. At the same time, the oil droplets are collected and guided along the honeycomb pore walls to prevent the oil mist from directly penetrating. Then, the vapor-liquid filter 21 can deeply adsorb, intercept and aggregate the fine oil mist and micro-droplets that are not completely separated by the honeycomb filter 222, further improving the oil mist separation accuracy and achieving fine purification. Through the multi-layer synergistic setting, a multi-stage separation structure combining coarse filtration and fine filtration can be formed, which effectively improves the oil mist separation efficiency and purification effect. Due to prolonged use, the contact surfaces of the honeycomb filter 222 and the intermediate gas-liquid filter 21, as well as the gas-liquid filter 21 itself, accumulate a large amount of sludge and oil. Regular disassembly and cleaning are necessary to maintain filtration performance. When cleaning is required, the regulating motor 32 is started. The output of the regulating motor 32 drives the regulating gear 33 to rotate slowly. The regulating gear 33 meshes with the regulating rack 12, causing it to move along the rack. This movement of the regulating gear 33 synchronously displaces the filter frame 221 and the honeycomb filter 222, while the filter frame 221 moves the limiting slider 4. 2. Slide along the limiting slide rail 41. The limiting slide rail 41 and the limiting slider 42 are used to limit and guide the movement of the filter frame 221, ensuring smooth and reliable movement. As the filter frame 221 and the honeycomb filter 222 continue to move, the originally tightly fitted honeycomb filter 222 and the gas-liquid filter 21 can be separated to form a cleaning gap. This setting effectively eliminates the problem of traditional structures being difficult to clean due to tight fit and lack of operating space. It facilitates the full entry of cleaning water between the filter screens, achieving a thorough rinsing of the gas-liquid filter 21, avoiding oil residue, and significantly improving the thoroughness of cleaning. Meanwhile, during the rotation of the adjusting gear 33, one of the adjusting gears 33 rotates under the drive of the adjusting motor 32 and meshes with the other adjusting gears 33 to drive them, so that all the adjusting gears 33 rotate synchronously. The adjusting gear 33 is connected to the honeycomb filter screen 222 through the adjusting shaft 223, and then drives the honeycomb filter screen 222 to rotate synchronously through the adjusting shaft 223, so that the originally vertically arranged honeycomb filter screen 222 gradually rotates to a horizontal state. The oil sludge accumulated at the edges of the honeycomb filter screen 222 can fall off naturally under the action of gravity, and it is easy for the cleaning water to directly rinse the edges and corners. This setting solves the problem that vertical arrangement causes oil to accumulate at the edges and cannot flow by itself, which easily forms oil sludge blockage. It effectively reduces the adhesion strength of oil sludge, improves the oil sludge cleaning efficiency, and ensures that the honeycomb channels are unobstructed. Furthermore, during the movement of the filter frame 221 and the honeycomb filter screen 222, since the filter frame 221 is connected to the sealing baffle 525, the filter frame 221 can drive the sealing baffle 525 to move synchronously, so that the sealing baffle 525 can release the blockage of the water outlet 523 of the cleaning cylinder 521, realizing the automatic opening of the water outlet 523. At the same time, the cleaning water is injected from the water inlet 522 at the top of the cleaning cylinder 521. The cleaning water continuously enters the interior of the cleaning cylinder 521 and drives the uniform turntable 524 to rotate under the force of the water flow. The uniform turntable 524 can make the cleaning water evenly and stably discharged from the water outlet 523 and thoroughly rinse the vapor-liquid filter screen 21 below. This setting can make the cleaning water evenly distributed and sprayed, ensuring that all parts of the vapor-liquid filter screen 21 can be fully rinsed, further improving the cleaning uniformity and cleaning effect. Simultaneously, the rotating turntable 524 drives the movable shaft 532 to rotate synchronously. The movable shaft 532 then drives the linkage turntable 533 to rotate. The linkage turntable 533 in turn drives the movable connecting rod to move up and down reciprocatingly. The movable connecting rod drives the movable rod 535 and the vibrating element 536 to move back and forth stably under the limiting and guiding action of the vibrating sleeve 531. When the vibrating element 536 moves down, it contacts the gas-liquid filter screen 21 and achieves intermittent knocking, so that the gas-liquid filter screen 21 generates high-frequency vibration while being washed by the cleaning water. This setting can loosen and remove the sludge attached to the gas-liquid filter screen 21 and the honeycomb filter screen 222 under the action of vibration. Combined with the water flow rinsing, it achieves a synergistic effect of vibration and washing, effectively enhancing the cleaning ability of stubborn sludge, avoiding sludge adhesion and residue, ensuring thorough cleaning of the filter screen, and effectively preventing the filter screen pores from clogging and extending the service life of the filter screen.
