Description
Technical Field
[0001] The invention relates to the technical field of kitchen fume purification, and in particular to an environmentally friendly fume purification and energy-saving device for commercial kitchens. Background Art
[0002] In commercial kitchen environments, due to frequent and large-scale cooking activities, a large amount of oil smoke is generated. Oil smoke contains a variety of harmful substances, such as grease particles, volatile organic compounds (VOCs), etc. If it is not effectively purified, it will not only pollute the internal environment of the kitchen, but also cause harm to the health of kitchen staff, and may also affect the air quality of the surrounding environment.
[0003] Many existing commercial kitchen fume filtration devices use a single filter structure. This single filter filter device has many shortcomings. First, during the continuous fume filtration process, the filter will gradually absorb a large amount of fume pollutants, and the filtration efficiency of the filter will decrease significantly as the use time increases. Due to the lack of self-cleaning function, when the filter is blocked to a certain extent, the operation of the entire fume purification device must be stopped to clean or replace the filter, which leads to the interruption of the fume purification work. In an environment such as commercial kitchens where the demand for fume purification is continuous and urgent, this interruption will cause the accumulation of fume in the kitchen, affecting the normal operation of the kitchen, and failing to ensure air quality in time.
[0004] Secondly, the cleaning process of a single filter is relatively complicated and time-consuming. Due to the lack of a dedicated partition design, the cleaning process may cause pollution or interference to other parts of the device, increasing the difficulty of cleaning and maintenance costs. Moreover, some existing filter devices are not satisfactory in terms of cleaning effect and cannot completely remove the oil fume pollutants adsorbed on the filter, which further affects the service life and filtration efficiency of the filter, making it difficult to maintain the performance of the entire oil fume filtration device at a stable and efficient level. Summary of the invention
[0005] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides an environmentally friendly oil fume purification and energy-saving device for commercial kitchens to solve the above problems.
[0006] (II) Technical solution To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an environmentally friendly oil fume purification and energy-saving device for a commercial kitchen, comprising an air intake duct, a mounting cover is installed at the air outlet end of the air intake duct, a filter cartridge is rotatably installed inside the mounting cover, the filter cartridge as a whole is composed of a mounting frame and filter core plates installed at four mounting positions in the front, back, left and right of the interior thereof, wherein the leftmost filter core plate is connected to the air outlet end of the air intake duct, an air outlet pipe connected to the inner center of the filter core plate is installed at the top of the mounting cover, a conversion drive mechanism for driving the filter core plate to rotate 90° at a time is installed at the top outside the air intake duct, a cleaning hood is installed on the right side of the mounting cover, a right quarter of the filter core plate is rotatably connected to the interior of the cleaning hood, a plurality of high-pressure nozzles for spraying liquid toward the filter core plates distributed in the cleaning hood for cleaning are evenly installed on the right side cover wall inside the cleaning hood, and a liquid supply mechanism for supplying liquid to the plurality of high-pressure nozzles is installed on the right side of the cleaning hood.
[0007] As a preferred technical solution of the present invention, the front and rear cover walls of the installation cover form an air intake duct and a cleaning cover to close the front and rear parts of the filter cartridge and prevent the oil fume filtering operation, so that only the filter core plate at the left side of the filter cartridge performs the oil fume filtering operation, and only the filter cartridge at the right side of the filter cartridge performs the cleaning operation.
[0008] As a preferred technical solution of the present invention, the conversion drive mechanism specifically includes the following structure: A stepper motor mounted on top of the air intake duct; A driving gear connected to the output end of the stepper motor; The transmission gear ring is installed on the upper end surface of the filter cartridge, and the driving gear and the transmission gear ring are meshed.
[0009] As a preferred technical solution of the present invention, the transmission ratio between the driving gear and the transmission gear ring is set to 40:1.
[0010] As a preferred technical solution of the present invention, the liquid supply mechanism specifically includes the following structure: A liquid collecting tank connected to the liquid inlet ends of a plurality of high-pressure nozzles; The liquid storage tank is distributed on the right side of the outside of the collecting tank; A pump body is installed on the liquid storage tank and the output end is connected to the inside of the liquid collecting tank.
[0011] As a preferred technical solution of the present invention, an electric heating tube for heating the internal liquid is installed inside the wall of the liquid storage tank.
[0012] As a preferred technical solution of the present invention, the lower half of the cleaning cover extends to the bottom of the mounting cover and is designed as a detachable collection box for disassembly and regular treatment of waste liquid after internal cleaning.
[0013] As a preferred technical solution of the present invention, a hatch for replacing a filter core plate rotated to a front position on the filter core barrel is installed on the front side wall of the mounting cover.
[0014] As a preferred technical solution of the present invention, the air outlet pipe is externally connected to an air extraction structure.
[0015] Compared with the prior art, the present invention provides an environmentally friendly oil fume purification and energy-saving device for commercial kitchens, which has the following beneficial effects: High efficiency and continuous filtration The four filter core plates inside the filter cartridge in the device perform oil fume filtering operations alternately. When the filter core plate on the far left performs oil fume filtering, the filter core plate on the far right can perform self-cleaning operations at the same time. This design ensures that the oil fume filtering work will not be interrupted due to the cleaning of the filter element, and the oil fume purification capacity is always maintained, which greatly improves the efficiency of kitchen oil fume purification and meets the purification needs of commercial kitchens that continuously generate oil fume.
[0016] Precise station switching The stepper motor in the conversion drive mechanism has the characteristic of precise control of the rotation angle. Through the 40:1 transmission ratio between the drive gear and the transmission ring, it can accurately drive the filter cartridge to rotate 90° at a time. This precise rotation control ensures that the four filter core plates switch positions in an orderly manner, so that the filtering and cleaning work can be carried out alternately and accurately, further ensuring the stability of the uninterrupted operation of the entire device.
[0017] Partitioning operations to improve efficiency The structure formed by the front and rear cover walls of the installation cover, the air intake duct and the cleaning cover enables only the filter core plate on the left side of the filter core barrel to perform oil fume filtering operations, while the filter core plate on the right side performs cleaning operations. This partitioning method of filtering and cleaning avoids mutual interference during the filtering and cleaning processes and improves the overall working efficiency of the device.
[0018] Good maintenance convenience The lower part of the cleaning cover extends to the bottom of the installation cover and is designed as a detachable collection box, which is convenient for regular disassembly and disposal of waste liquid after internal cleaning to keep the inside of the cleaning cover clean. At the same time, a hatch is installed on the front side wall of the installation cover, and the filter core plate can be replaced when it is rotated to the front position. This design facilitates the maintenance of the filter core plate, ensuring that the filtering effect of the filter core plate is always good, and reducing the risk of device performance degradation due to inconvenient filter element maintenance.
[0019] Enhanced cleaning effect Several high-pressure nozzles evenly installed on the right side of the cleaning hood can generate high-pressure liquid spray to clean the filter core plate with strong spraying, effectively removing the oil fume pollutants adsorbed on the filter core plate. In addition, an electric heating pipe is installed inside the tank wall of the liquid storage tank to heat the internal liquid, improve the cleaning effect of the cleaning liquid, further ensure the cleaning quality of the filter core plate, thereby extending the service life of the filter core plate and helping to maintain the efficient filtering performance of the device.
[0020] This environmentally friendly oil fume purification and energy-saving device for commercial kitchens achieves self-cleaning and uninterrupted oil fume filtering operation through its unique structural design, especially the alternating working mode of the filter cartridge and its internal filter core plate. This creative design has many advantages in the commercial kitchen environment. First, the efficient and uninterrupted filtering capacity can continuously purify the oil fume generated in the kitchen, reduce the pollution of oil fume in the kitchen, improve the working environment of the kitchen, and have a positive protective effect on the health of kitchen staff. Secondly, the precise station switching mechanism ensures the stability and reliability of the device operation and reduces the failures that may be caused by inaccurate switching. Furthermore, the partitioned operation of filtering and cleaning and the good maintenance convenience enable the device to maintain an efficient working state during long-term use and reduce maintenance costs. Finally, the enhanced cleaning effect not only helps to maintain the performance of the device, but also saves resources to a certain extent, because good cleaning effect means that the filter core plate does not need to be replaced frequently, which is in line with the concept of environmental protection and energy saving. In summary, the device has high practical value and promotion significance in the field of commercial kitchen oil fume purification. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] See also Figure 1-7 A commercial kitchen environment-friendly oil fume purification and energy-saving device comprises an air intake pipe 1, and a mounting cover 2 is installed at the air outlet end of the air intake pipe 1. The mounting cover 2 is a relatively closed space, and its function is to provide a suitable environment for filtering oil fume and cleaning filter elements.
[0027] A filter cartridge 3 is rotatably installed inside the mounting cover 2. The mounting frame 31 of the filter cartridge 3 plays a supporting and fixing role. Filter core plates 32 are installed at four mounting positions inside the mounting cover 2, front, back, left and right. The four filter core plates 32 perform oil fume filtering operations alternately. When the filter core plate 32 rotates to the leftmost position for filtering, the filter core plate 32 at the rightmost position can perform a self-cleaning operation, thereby achieving uninterrupted oil fume filtering. The filter core plates 32 use high-efficiency oil fume filtering materials that can effectively absorb harmful substances in oil fume. The filter core plate 32 on the far left is connected to the outlet end of the air inlet pipe 1 to ensure that the oil fume can enter the filter core plate 32 for filtration. An outlet pipe 8 connected to the center of the filter cartridge 3 is installed at the top of the mounting cover 2. The outlet pipe 8 is externally connected to a suction structure to discharge the filtered gas through suction.
[0028] A conversion drive mechanism 4 is installed on the top of the air intake pipe 1, which includes a stepper motor 41 installed on the top of the air intake pipe 1. The stepper motor 41 has the characteristic of accurately controlling the rotation angle. The drive gear 42 docked on the output end of the stepper motor 41, and the transmission gear ring 43 installed on the upper end surface of the filter cartridge 3 and meshing with the drive gear 42, the transmission ratio between the drive gear 42 and the transmission gear ring 43 is 40:1. Such a design can ensure that the stepper motor 41 can accurately drive the filter cartridge 3 to rotate 90° at a time, and realize the orderly switching of the four filter core plates 32.
[0029] A cleaning cover 5 is installed on the right side of the installation cover 2, and the cleaning cover 5 provides a special space for cleaning the filter core plate 32. The right quarter of the filter core plate 32 is rotated and connected to the inside of the cleaning cover 5. A number of high-pressure nozzles 6 are evenly installed on the right cover wall inside the cleaning cover 5. These high-pressure nozzles 6 can generate high-pressure liquid spray, which can spray liquid strongly on the filter core plate 32 distributed in the cleaning cover 5 to effectively remove the oil smoke pollutants adsorbed on the filter core plate 32.
[0030] A liquid supply mechanism 7 is installed on the right side of the cleaning cover 5, which includes a liquid storage tank 71 distributed on the right side of the outside of the liquid collecting box 73, and the liquid storage tank 71 stores liquid for cleaning. A pump body 72 is installed on the liquid storage tank 71 and the output end is connected to the inside of the liquid collecting box 73. The pump body 72 can transport the cleaning liquid in the liquid storage tank 71 to the liquid collecting box 73, and then the liquid collecting box 73 distributes it to each high-pressure nozzle 6. An electric heating pipe is installed inside the tank wall of the liquid storage tank 71 to heat the internal liquid and improve the cleaning effect of the cleaning liquid.
[0031] The front and rear cover walls of the installation cover 2, the air intake duct 1 and the cleaning cover 5 form a structure that closes the front and rear parts of the filter cartridge 3, so that only the filter core plate 32 at the left side of the filter cartridge 3 performs the oil fume filtering operation, thereby ensuring the targeted and efficient oil fume filtering; and only the filter cartridge 32 at the right side of the filter cartridge 3 performs the cleaning operation, thereby realizing the partitioning of filtering and cleaning and improving the working efficiency of the device.
[0032] The lower part of the cleaning cover 5 extends to the bottom of the installation cover 2 and is designed to be a detachable collection box, which is convenient for regular disassembly and disposal of waste liquid after internal cleaning, and keeps the inside of the cleaning cover 5 clean. A hatch 21 is installed on the front side wall of the installation cover 2. When the filter core plate 32 on the filter cartridge 3 rotates to the front position, it can be replaced by opening the hatch 21 to ensure that the filtering effect of the filter core plate 32 is always maintained at a good level.
[0033] Working principle: In actual use, oil smoke enters through the air intake pipe 1, and after being filtered by the filter core plate 32 on the far left, the purified gas is discharged through the air outlet pipe 8. After the filter core plate 32 has been used for a period of time, the conversion drive mechanism 4 is started to drive the filter core barrel 3 to rotate 90°, so that the filter core plate 32 used last time enters the cleaning cover 5 for cleaning, and at the same time, the other unused filter core plate 32 rotates to the air outlet end of the air intake pipe 1 for oil smoke filtering. The pump body 72 pumps the cleaning liquid in the liquid storage tank 71 into the liquid collection box 73, and then sprays it to the filter core plate 32 through the high-pressure nozzle 6 for cleaning. The waste liquid after cleaning is collected in the detachable collection box in the lower half of the cleaning cover 5 and is processed regularly. When the filter core plate 32 needs to be replaced, it can be operated by opening the cabin door 21.
