Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil fume treatment, in particular to a restaurant oil fume treatment device. Background Art
[0002] Restaurant fumes are a mixture of smoke and gas produced by the burning of fat, grease, water and other ingredients during the cooking process. When cooking in the kitchen, the grease in the ingredients will produce vapor at high temperatures, and these vapors will condense into tiny oil droplets when encountering cooling air, forming fumes. These fumes may also contain smoke, organic matter and odor substances. Untreated restaurant fumes contain a large amount of pollutants, such as particulate matter, volatile organic compounds, smoke, odor, etc. If they are directly discharged outdoors, they will cause serious pollution to the surrounding environment, affect air quality, and even cause environmental pollution and ecological problems.
[0003] The restaurant fume treatment devices currently used often cool the fume passing through the fume duct by installing semiconductor refrigeration sheets, circular aluminum plates and condensation cores in the fume duct, causing the gaseous fume to condense into liquid particles, and promoting the agglomeration of fine particles to form large particles, thereby improving the purification efficiency of the electrostatic precipitator and reducing the exhaust flue gas temperature.
[0004] However, when using this method, the filter plate cannot be cleaned. After long-term use, the filter plate in the oil fume treatment device will accumulate a lot of oil fume and dirt. If it is not cleaned regularly, the dirt will clog the pores of the filter plate and reduce the filtration efficiency. This means that more oil fume and harmful substances will pass through the device without being filtered, thereby increasing the risk to the surrounding environment and human health, and increasing the resistance of the oil fume treatment device, causing the device to require more energy to push the oil fume through. This will not only increase the energy consumption of the equipment, but also accelerate the wear of the equipment, increase the operation and maintenance costs and repair expenses.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Reference Figure 1 , Figure 2 and Figure 4, the utility model provides an embodiment: a restaurant oil fume treatment device, including a shell 1, a filter plate 3 is slidably connected inside the shell 1, backing plates 4 are fixedly connected to the outer sides of the shell 1, the upper parts of the two backing plates 4 are fixedly connected to cylinders 5, the output ends of the two cylinders 5 are fixedly connected to push plates 6, the upper sides of the filter plate 3 are fixedly connected to connecting rods 7, the upper part of the connecting rods 7 is fixedly connected to the push plates 6, the upper sides of the shell 1 are fixedly connected to fixed frames 8, and the sides away from the two fixed frames 8 are fixedly connected to hydraulic cylinders 9, hydraulic The output end of the cylinder 9 is fixedly connected to a mounting plate 10, and a cleaning brush 11 is provided on opposite sides of the two mounting plates 10. A buffer assembly is fixedly connected to one side of the fixed frame 8, and the buffer assembly includes a fixed rod 12, and the fixed rod 12 is fixedly connected to one side of the fixed frame 8. A moving rod 14 is slidably connected inside the fixed rod 12, and the other end of the moving rod 14 is fixedly connected to the mounting plate 10, and a buffer spring 13 is fixedly connected inside the fixed rod 12, and the other end of the buffer spring 13 is fixedly connected to the moving rod 14. The left part of the shell 1 is fixedly connected to the smoke inlet pipe 2.
[0025] During the operation of the oil fume treatment device, the suction fan 24 is started. The suction fan 24 can generate a strong suction force, so that the oil fume generated in the kitchen is quickly sucked into the interior of the shell 1 through the smoke inlet pipe 2. The filter plate 3 is a key component in the oil fume treatment device. It has excellent filtering performance and can effectively block large particles in the oil fume, thereby protecting subsequent processing equipment from damage. When the cleanliness of the filter plate 3 drops to a certain level, the system will automatically start the two cylinders 5. The output end of the cylinder 5 is connected to the push plate 6 through a mechanical transmission. When the cylinder 5 is working, it will push the push plate 6 to move upward. During the movement, the push plate 6 will drive the filter plate 3 to move upward together through the connecting rod 7. In this way, the filter plate 3 can gradually be removed from the interior of the shell 1. The parts are disengaged for easy cleaning. At the same time, the hydraulic cylinder 9 also starts to work. The output end of the hydraulic cylinder 9 is connected to the mounting plate 10. When the hydraulic cylinder 9 pushes the output end to move, the two mounting plates 10 will gradually approach each other. In the process of moving the mounting plates 10, they will drive the moving rod 14 to move together. The moving rod 14 is connected to the buffer spring 13. When the moving rod 14 moves, the buffer spring 13 will be stretched. The existence of the buffer spring 13 can not only play a buffering role, but also ensure the smooth progress of the cleaning process. Under the action of the buffer spring 13, the two mounting plates 10 drive the cleaning brush 11 to gradually approach the filter plate 3. When the cleaning brush 11 contacts the filter plate 3, the oil stains and dirt on the filter plate 3 can be cleaned.
[0026] Reference Figure 1-Figure 3A water pump 19 is fixedly connected to the upper part of the shell 1, a connecting pipe 18 is fixedly connected to the input end of the water pump 19, a water tank 17 is fixedly connected to the other end of the connecting pipe 18, a water pipe 20 is fixedly connected to the output end of the water pump 19, a drain pipe 21 is fixedly connected to the other end of the water pipe 20, a nozzle 22 is arranged at the bottom of the drain pipe 21, the drain pipe 21 is fixedly connected to the inside of the shell 1, a liquid outlet pipe 16 is arranged at the bottom of the shell 1, a filter plate 15 is fixedly connected to the inside of the shell 1, a nozzle 22 is arranged on the upper part of the filter plate 15, a water tank 17 is fixedly connected to the upper part of the shell 1, a smoke exhaust pipe 25 is fixedly connected to the left part of the shell 1, an activated carbon filter plate 23 is fixedly connected to the inside of the shell 1, and a suction fan 24 is arranged on the left part of the inside of the shell 1.
[0027] When the oil smoke passes through the filter plate 15, the main task of the plate is to capture large particles of oil smoke and impurities. These impurities mainly include grease particles, food residues, etc. The filter plate 15 can effectively capture these large particles of impurities. Clean water mixed with a degreasing agent is introduced into the water tank 17. Then, the water pump 19 is started. The water pump 19 draws clean water from the water tank 17 through the connecting pipe 18 and transports it to the drain pipe 21 through the water pipe 20. Finally, the clean water is evenly sprayed on the surface of the filter plate 15 through the nozzle 22. The process effectively removes the oil, dirt and solid particles on the filter plate 15, prevents pore blockage and surface fouling, and ensures the continuous and efficient operation of the filter plate 15. The activated carbon has a highly developed pore structure and a huge surface area, and can absorb a large amount of organic matter, odor and harmful gases. When the oil smoke passes through the activated carbon filter plate 23, the odor and pollutants therein are effectively adsorbed, thereby achieving further purification of the oil smoke. Finally, the oil smoke treated by the activated carbon filter plate 23 is discharged to the outside through the exhaust pipe 25.
[0028] Working principle: First, start the suction fan 24 to make the oil smoke be sucked into the interior of the shell 1 through the smoke inlet pipe 2, and under the action of the filter plate 3, preliminary filtration is carried out. After the filter plate 3 has been used for a long time, start the two cylinders 5, and the output end of the cylinder 5 pushes the push plate 6 to move upward. When the push plate 6 moves, it drives the filter plate 3 connected by the connecting rod 7 to move upward, so that the filter plate 3 slowly moves upward from the inside of the shell 1, and at the same time start the hydraulic cylinder 9, and the output end of the hydraulic cylinder 9 pushes the two mounting plates 10 close to each other. When the mounting plate 10 moves, it drives the moving rod 14 to move. The movement of the moving rod 14 stretches the buffer spring 13. Under the action of the buffer spring 13, the two mounting plates 10 drive the cleaning brush 11 to approach each other, so that the cleaning brush 11 contacts the filter plate 3, and the oil stains on the filter plate 3 are cleaned, thereby effectively cleaning the filter plate 3, removing the accumulated dirt and grease, restoring the original state of the filter plate 3, maintaining its efficient filtering performance, and ensuring the oil smoke treatment device In the normal operation of the device, the oil smoke after preliminary filtration passes through the filter plate 15, which is used to capture large particles of oil smoke and impurities, such as grease particles, food residues, etc., and clean water mixed with a degreasing agent is introduced into the water tank 17, and then the water pump 19 is started. The water pump 19 pumps water from the inside of the water tank 17 through the connecting pipe 18, and the water is transported to the drain pipe 21 through the water pipe 20, and finally sprayed to the surface of the filter plate 15 through the nozzle 22 to rinse the filter plate 15. The cleaned water is discharged outwardly through the liquid outlet pipe 16, thereby achieving effective cleaning of the filter plate 15, which can effectively clean the oil, dirt and solid particles on the surface of the filter plate 15 to prevent pore blockage and surface fouling. Then the oil smoke passes through the activated carbon filter plate 23, which is used to absorb organic matter, odor and harmful gases in the oil smoke, and can effectively remove odor and pollutants in the oil smoke. Finally, the treated oil smoke is discharged outwardly through the exhaust pipe 25.
