Description

Technical Field

[0001] The invention relates to the technical field of smoke filtering of UV fume hoods, in particular to a smoke filter for UV fume hoods. Background Art

[0002] UV hood is a device that uses ultraviolet technology to treat the smoke generated in the kitchen or other places. The air filter is the main component of the UV hood. The smoke in the UV hood can be filtered and purified through the air filter. This can not only remove harmful gases and odors in the smoke, but also prevent the particles in the smoke from blocking the ultraviolet rays in the UV hood.

[0003] The patent name disclosed in the prior art with application number "CN202211196317.8" is "A flue gas purification device", which discloses that the purification box cools and purifies the gas through the purification liquid inside it. During the purification process, the dispersion plate swings under the vibration of the elastic vibration member, and the gas discharged from the first connecting pipe is dispersed by the continuous swing of the dispersion plate, so that the gas is converted into a number of tiny bubbles, so that the gas is fully in contact with the purification liquid, thereby improving the purification and cooling effect of the purification liquid on the gas. In addition, the continuous swing of the dispersion plate further causes the purification liquid to continuously change its position to ensure the purification effect of the purification liquid, and then the gas enters the interior of the adsorption box through the second connecting pipe, and the gas is further purified by the adsorption plate, and then the purified gas is discharged through the exhaust hose, so that the flue gas is cooled and purified multiple times through the mutual cooperation of multiple structures, so that the purification effect of the purification device on the flue gas is better;

[0004] The patent name disclosed in the prior art with application number "CN200910248645.6" is "fog-type kitchen oil fume purifier", which discloses that the oil is discharged from the other side through the fog-type filter device in the cabinet. Since the right-angled metal mesh is arranged longitudinally and distributed in a right-angled stack, each layer of smoke must pass through at least four to six layers of metal mesh to fully improve and play the role of the metal mesh. The metal mesh cooperates with the water mist sprayed from the water spray pipe, which can disperse and refine the water mist and enhance the ability of the water mist to capture oil fume. At the same time, the metal mesh structure has a good ability to collect water droplets that capture smoke. The inclined metal mesh surface is conducive to the falling of the attached water droplets. The oil cannot adhere to the metal mesh surface under the action of the water flow. The oil is attached to the water droplets and flows out of the cabinet into the circulating water pool with the water flow. The oil adsorbs each other and floats on the upper surface of the pool. It can be collected and processed manually, or it flows out from the overflow port on the circulating water pool and is discharged into the sewer.

[0005] When the smoke filter is in use, the water mist sprayed from the water spray pipe is used to treat the oil smoke. However, since the water spray pipe is fixedly installed, the coverage area of ​​the water mist sprayed from the water spray pipe is fixed, resulting in that the smoke and the water mist cannot contact with a large area, so that part of the smoke cannot contact with the water mist well, thus resulting in incomplete treatment of the smoke by the smoke filter in the later stage;

[0006] Therefore, we propose a fume filter for UV fume hood to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0051] Embodiment 1: The smoke filter for UV smoke hood in this embodiment can increase the contact area between smoke and water when in use, so that the oil mist particles in the smoke can be well contacted with water and captured, thereby facilitating the treatment of the oil mist particles in the smoke. The specific structure is shown in the attached Figure 1-Figure 7 As shown, it includes an outer shell 1, and an activated carbon adsorption plate 7 installed in the rear side of the outer shell 1, two groups of funnel-shaped deflectors 2 are symmetrically installed inside the front side of the outer shell 1, the rear side of the deflector 2 passes through the front support baffle 8 installed in the front side of the outer shell 1, the rear side of the deflector 2 is connected to the wet washing frame 10 through a sealed bearing, the rear side of the wet washing frame 10 is connected to the connecting ring 9 through a sealed bearing, the rear side of the connecting ring 9 passes through the rear support baffle 11 installed in the rear side of the outer shell 1, the rear side of the connecting ring 9 is installed with a dust collection filter frame 12, and the rear side of the dust collection filter frame 12 is provided with an activated carbon adsorption plate 7;

[0052] The rear end of the control rod 17 is installed in the connecting ring 9 through the mounting frame 16, and the front end of the control rod 17 is inserted into the wet washing frame 10. The outer side of the control rod 17 is provided with a toggle plate 18 for stirring the smoke. A second water storage chamber 101 is provided inside the front side of the wet washing frame 10, and atomizing nozzles are installed at equal intervals on the inner wall of the wet washing frame 10. A self-rotation control mechanism is installed on the outer side of the wet washing frame 10. A first water storage chamber 201 is provided inside the rear side of the air guide cover 2. An upper shunt pipe 5 is installed above the air guide cover 2. The upper end of the upper shunt pipe 5 passes through the upper surface of the outer shell 1 and is connected to the upper main pipe 6. A lower shunt pipe 4 is installed through the lower front side of the air guide cover 2. The lower end of the lower shunt pipe 4 passes through the lower surface of the outer shell 1 and is connected to the lower main pipe 3. A baffle plate 202 with a circular ring structure is installed on the front side of the air deflector 2, and the inner diameter of the baffle plate 202 is smaller than the inner diameter of the front end of the air deflector 2. The space in the first water storage chamber 201 is connected to the space in the second water storage chamber 101. The first water storage chamber 201 and the second water storage chamber 101 are both arranged in a circular ring structure. The rotation control mechanism includes a gear ring 13 installed on the outside of the wet washing frame 10, and also includes a support frame 14 installed between the two wet washing frames 10. Side rack assemblies 141 are installed on both sides of the support frame 14 with a "U" shape structure. The outer side of the side rack assembly 141 is meshed with the gear ring 13. An electric push rod 15 is installed inside the upper part of the support frame 14, and the upper end of the electric push rod 15 is connected to the inside of the outer shell 1.

[0053] First, install the entire smoke filter in the UV smoke hood, start the suction fan in the UV smoke hood, and then the entire smoke filter can be used. At this time, the external smoke first enters the funnel-shaped guide cover 2, and then the smoke in the guide cover 2 enters the wet washing frame 10. At the same time, the right end of the upper main pipe 6 is connected to the external water supply mechanism. At this time, the external water enters the upper main pipe 6, and then the upper main pipe 6 transports the water to the upper shunt pipe 5. At this time, the water in the upper shunt pipe 5 enters the first water storage chamber 201, and the water in the first water storage chamber 201 enters the second water storage chamber 101. Then the water in the second water storage chamber 101 is sprayed outward through a circle of atomizing nozzles on the inner wall of the wet washing frame 10;

[0054] At the same time, the electric push rod 15 is started, and the output end below the electric push rod 15 drives the support frame 14 to rise and fall reciprocatingly, thereby causing the support frame 14 to drive the side rack assemblies 141 on the left and right sides to rise and fall reciprocatingly together. At this time, the side rack assembly 141 is meshed with the gear ring 13, driving the gear ring 13 and the wet washing frame 10 to perform reciprocating clockwise and counterclockwise rotation at a certain angle. The two ends of the wet washing frame 10 are respectively connected to the connecting ring 9 and the air guide cover 2 through sealed bearings, thereby ensuring the stable rotation of the wet washing frame 10, so that the wet washing frame 10 can drive the atomizing nozzle on the inner wall to rotate together. Reciprocating rotation is performed, and the rotating atomizing nozzle in the wet washing frame 10 sprays water evenly in all directions, and then the evenly distributed water can contact the flue gas at all positions in the wet washing frame 10. At this time, the sprayed water contacts the oil mist particles in the flue gas, so that the gravity of the oil mist particles increases and automatically falls. Since the flue gas filter is installed in an inclined shape, the water and the oil mist particles flow into the guide cover 2, and are blocked by the annular baffle 202, so that the mixed water and oil mist particles are discharged through the lower shunt pipe 4 and the lower main pipe 3, so that the flue gas filter can well remove the oil mist particles in the flue gas;

[0055] Then, the flue gas with the oil mist particles removed flows into the dust collecting filter frame 12 through the connecting ring 9, and the particulate impurities in the flue gas are further filtered through the dust collecting filter frame 12, so that the particulate impurities in the gas remain in the dust collecting filter frame 12, and the flue gas is discharged outward through the mesh holes around the dust collecting filter frame 12, and then the flue gas contacts the activated carbon adsorption plate 7, and the activated carbon adsorption plate 7 adsorbs the organic compounds and odors in the flue gas, thereby purifying the flue gas, and then the treated flue gas flows into the UV hood. At this time, the particulate matter in the flue gas has been removed by the flue gas filter, so that the particulate matter in the flue gas will not block the ultraviolet rays in the UV hood, which can protect the ultraviolet rays from pollution and extend the service life of the ultraviolet lamp. Then, the ultraviolet lamp in the UV hood can further process the flue gas, so that the flue gas filter can process the flue gas well, avoid the flue gas from polluting the environment, and protect the environment well.

[0056] Embodiment 2: The smoke filter for UV smoke hood in this embodiment can further increase the contact area between smoke and water on the basis of embodiment 1, so that the water can process the oil mist particles in the smoke more thoroughly. For the specific structure, refer to the attached Figure 8-Figure 11As shown, a connecting rod 181 with a "T"-shaped structure is slidably connected inside the outer side surfaces of the four sides of the control rod 17, a toggle plate 18 with an arc-shaped structure is installed on the outer end of the connecting rod 181, a connecting spring 182 is nested and connected to the outer side of the outer end of the connecting rod 181, one end of the connecting spring 182 is connected to the outer side surface of the control rod 17, a first flow tube 171 is installed through the outer side of the rear end of the control rod 17, a second flow tube 172 is installed in a groove inside the rear end of the control rod 17, a first air storage airbag 173 is installed in a groove inside the front end of the control rod 17, one end of the first flow tube 171 is connected to the second flow tube 172, the other end of the second flow tube 172 is connected to the first air storage airbag 173, and a connecting rod 181 is arranged on the outer side of the first air storage airbag 173. A second air storage bag 20 and an extrusion plate 19 are installed in a groove inside the front side of the rear support baffle 11, and a second air storage bag 20 is arranged on the rear side of the extrusion plate 19. Two first flow tubes 171 in a "7" shape are symmetrically installed on the rear side of the second air storage bag 20. The extrusion plate 19 forms a sliding structure with the rear support baffle 11 through a self-propelled mechanism. A threaded rod 21 is threadedly connected to the lower interior of the extrusion plate 19. The rear end of the threaded rod 21 is connected to the interior of the rear support baffle 11, and the outer side of the front end of the threaded rod 21 is connected to a gear 211. The self-propelled mechanism includes a rear rack assembly 142 installed on the rear side of the support frame 14, and the rear rack assembly 142 is meshed with the gear 211; the extrusion plate 19 moves back and forth in a groove in the rear support baffle 11 through the threaded rod 21.

[0057] When the support frame 14 is lifted and lowered reciprocatingly, the rear rack assembly 142 in the self-propelled mechanism will be driven to lift and lower reciprocatingly, so that the rear rack assembly 142 drives the gear 211 to rotate reciprocatingly clockwise and counterclockwise at a certain angle, so that the gear 211 drives the threaded rod 21 to rotate reciprocatingly clockwise and counterclockwise at a certain angle. At this time, when the threaded rod 21 rotates, it drives the extrusion plate 19 connected to the outer thread to move back and forth reciprocatingly, and then when the extrusion plate 19 moves backward, it will squeeze the second air storage airbag 20. At this time, the gas in the second air storage airbag 20 flows into the first air storage airbag 173 through the first flow tube 171 and the second flow tube 172, and then the volume expansion of the first air storage airbag 173 applies an outward thrust to the connecting rod 181, and then the connecting rod 181 drives the toggle plate 18 to move outward, and the connecting spring 182 accumulates force at this time.

[0058] When the squeezing plate 19 moves forward, the stored force of the connecting spring 182 automatically drives the toggle plate 18 to move inward. Such repeated operations cause the toggle plate 18 to move outward in a reciprocating manner. Therefore, the toggle plate 18 can not only stir part of the flue gas in the wet washing frame 10, but also toggle part of the flue gas in the wet washing frame 10 toward the direction of the atomizing nozzle, thereby increasing the fluidity of the flue gas in the wet washing frame 10, and further increasing the contact area between the flue gas and the sprayed water, so that the water can more thoroughly treat the oil mist particles in the flue gas. Then, the flue gas can continue to be filtered as shown in Example 1.

[0059] Embodiment 3: The smoke filter for UV smoke hood in this embodiment discloses another self-propelling mechanism based on the embodiment 2. The specific structure is shown in the attached figure. Fig.12 As shown, a protrusion 191 is installed on the front side of the extrusion plate 19, and a limiting rod 22 with a "T"-shaped structure is slidably connected to the lower interior of the extrusion plate 19. The rear end of the limiting rod 22 is connected to the interior of the rear support partition 11, and a return spring 221 is nested and connected to the outer side of the rear end of the limiting rod 22; the self-propelled mechanism includes a push block 143 installed on the rear side of the support frame 14, and a protrusion 191 is arranged below the push block 143, and the protrusion 191 is arranged in an inclined shape on a side close to the push block 143.

[0060] When the support frame 14 is lifted and lowered reciprocatingly, the push block 143 in the self-propelling mechanism is also lifted and lowered reciprocatingly. When the push block 143 moves downward, the push block 143 pushes downward a convex block 191 with an inclined side surface, and the convex block 191 drives the extrusion plate 19 to move backward.

[0061] Then, when the extrusion plate 19 moves backward as shown in Example 2, the second air storage bag 20 is squeezed in the same way, and then the volume expansion of the first air storage bag 173 exerts an outward thrust on the connecting rod 181. At this time, the connecting rod 181 drives the toggle plate 18 to move outward, which can further increase the contact area between the flue gas and the sprayed water, so that the water can treat the oil mist particles in the flue gas more thoroughly. Then, as shown in Example 1, the flue gas can continue to be filtered, thereby completing a series of tasks.

[0062] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
