Technical Field
[0001] This utility model relates to the technical field of marine kitchen fume collection hoods, specifically to a marine self-cleaning fume purification device. Background Technology
[0002] A fume hood is a device used in ship kitchens to remove cooking fumes and improve the kitchen environment. It is an essential piece of equipment in ship kitchens, used to collect cooking fumes and steam generated during cooking. The fumes are then exhausted outdoors through filtration or exhaust systems, keeping the kitchen air fresh. Its main function is to collect harmful gases, fumes, or dust by suction or guiding airflow, preventing them from spreading into the surrounding environment, thereby protecting personnel health and environmental safety.
[0003] Prolonged use of marine kitchen fume collection hoods can lead to excessive grease residue on the mesh, making it difficult to clean. Furthermore, cleaning the inside of the mesh is challenging, requiring it to be removed and cleaned separately, which is time-consuming and labor-intensive. In addition, current marine kitchen fume collection hoods lack intelligence. Therefore, this application proposes a marine self-cleaning fume purification device to address the aforementioned shortcomings. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0030] Reference Figure 1 , Figure 2 and Figure 3 A marine self-cleaning oil fume purification device includes two sets of symmetrically arranged purification bodies 1. Each set of purification bodies 1 includes a support frame 2, an LED lighting lamp 3, a cover plate 4, a heat dissipation hole 5, an oil screen 7, a sewage and water collection trough 8, a drainage connector 9, a differential separation disc 10, a limit plate 11, a water inlet pipe 12, a water valve 13, and a water pipe 14.
[0031] Taking one of the purification bodies, 1, as an example:
[0032] Reference Figure 4The support frame 2 is provided in two sets, and each set of support frame 2 is connected to an inclined oil mesh 7. A wastewater collection trough 8 is connected between the bottoms of the two sets of oil mesh 7. The bottom of the oil mesh 7 can extend into the wastewater collection trough 8. A drain connector 9 is installed at the bottom of the wastewater collection trough 8 to drain the wastewater after subsequent cleaning. When used later, the oil stains on the oil mesh 7 and the water stains after cleaning can fall into the wastewater collection trough 8. The wastewater collection trough 8 and the oil mesh 7 are detachably connected, and can be directly removed for cleaning later. A heat dissipation hole 5 is also provided on one side of the support frame 2.
[0033] Reference Figure 4 , Figure 5 and Figure 6 A limiting plate 11 is installed above the oil mesh 7. The limiting plate 11 has a "V" shape and is located directly above the oil mesh 7 with a certain gap between it and the oil mesh 7. The two ends of the limiting plate 11 are installed on the support frame 2 and can be disassembled later. Several limiting installation holes are equally spaced on the limiting plate 11 for installing differential separation discs 10. Multiple differential separation discs 10 work simultaneously. Under the action of centrifugal motion, the centrifugal force generated by the rotating airflow separates the smoke particles, and the interception efficiency of oil smoke particles larger than 1μm reaches more than 90%.
[0034] Reference Figure 4 , Figure 5 and Figure 6 A water pipe 14 is installed inside the limiting plate 11. The water pipe 14 is connected to the water inlet pipe 12 located on the support frame 2 via a connecting pipe. A water valve 13 is installed on the water inlet pipe 12. The connector of the water inlet pipe 12 is left in the outside air for subsequent water supply. A cover plate 4 is installed between the two support frames 2 and above the limiting plate 11. The water pipe 14, the water inlet pipe 12 and the water valve 13 work together to form a cleaning device, which facilitates cleaning of the oil screen, maximizes internal cleanliness, and avoids oil stains from accumulating and affecting the overall smoke exhaust effect.
[0035] Reference Figure 2 and Figure 4 An LED light 3 is installed on the support frame 2 and on one side of the oil mesh 7 for lighting the oil fume purification device.
[0036] A control module 6 is installed on one of the purification units 1. The control module 6 is electrically connected to the LED lighting 3, the differential separation plate 10, and the water valve 13. The integrated control module includes a control panel and an integrated circuit board, which can control the equipment's operating status and parameters in real time. This allows the fume hood (oil fume purification device) to be started and stopped independently, which has advantages such as safety, environmental protection, and reliability.
[0037] The specific operating principle of this application is as follows:
[0038] When in use, the differential separation disc 10 can be opened by controlling the control module 6 via the switch. Since the differential separation disc 10 is located above the oil screen 7, it can draw oil fumes into the space between the limit plate 11 and the oil screen 7 through the oil screen 7. Subsequently, the oil stains fall into the waste and water collection tank 8 by gravity. Then, the waste and water collection tank 8 can be pulled out and cleaned.
[0039] If it is necessary to clean the inside of the gas collection hood, the water valve 13 can be turned on, and external water will enter the water pipe 14 through the water inlet pipe 12. The water from the water pipe 14 will be sprayed from the water pipe outlet onto the oil screen 7, thereby cleaning the oil screen 7 and the space between the oil screen 7 and the limiting plate 11. The water outlet of the water pipe 14 is also equipped with an automatic nozzle, and the water flow rate is adjustable, which helps to clean the gas collection hood.
[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
