Description

Technical Field

[0001] This utility model relates to the field of kitchen exhaust gas emission technology, and in particular to an improved structure of a water-cooled fume hood control box based on an oil fume treatment device. Background Technology

[0002] In commercial kitchens and catering establishments, cooking processes generate a large amount of oily fumes. These fumes not only contain grease particles, food residue, and pollutants, but also have a pungent odor and harmful chemicals, such as benzo[a]pyrene and polycyclic aromatic hydrocarbons. If directly emitted into the atmosphere, they will seriously damage ambient air quality, leading to smog and acid rain. Therefore, water-cooled fume hood control boxes are needed for fume treatment equipment.

[0003] A search revealed Chinese Patent Publication No. CN205447897U, which discloses a water fume hood control box, comprising a water inlet system and a water outlet system. A filter structure is installed on the pipeline between the water inlet system and the water outlet system. The water inlet system includes an inlet tank, and the water outlet system includes an outlet tank. An outlet solenoid valve is installed between the filter structure and the outlet tank. The inlet tank has a return water inlet, and a return water pipeline is connected to the filter structure. The return water pipeline is equipped with a return water solenoid valve. The outlet tank is equipped with a water quality sensor and a control circuit. A multi-parameter detector outputs a sampling voltage based on water quality. The control circuit includes a reference module providing a reference voltage and a comparison module coupled to the water quality sensor and the reference module. When the sampling voltage is greater than the reference voltage, a control signal is output to close the outlet solenoid valve and simultaneously open the return water solenoid valve. Existing water-cooled fume hood control boxes have ventilation holes on their casings. These holes are designed to allow hot air inside the control box to dissipate naturally, while also facilitating the entry of cool air from the outside, creating natural convection cooling. However, during daily use, these ventilation holes easily trap dust, hair, and oily debris from the air. Over time, this accumulation can narrow or even block the channels of the ventilation holes, hindering normal airflow, reducing cooling efficiency, and ultimately affecting the cooling effect. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an improved structure for a water-cooled fume hood control box based on an oil fume treatment device. The aim is to improve the problem in the prior art where the heat dissipation holes easily attract dust, hair, and oily debris from the air. Over a long period of time, this can narrow or even block the channels of the heat dissipation holes, hindering normal air circulation, reducing heat dissipation efficiency, and thus affecting the heat dissipation effect.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an improved structure of a water-cooled fume hood control box for oil fume treatment equipment, comprising a water-cooled fume hood control box and a scraper. A protective shell is fixedly connected to the bottom left side of the outer wall of the water-cooled fume hood control box. A motor is fixedly connected to the inner right side of the protective shell. A rotating fan is fixedly connected to the output end of the motor. A filter screen is fixedly connected to the bottom left side of the inner wall of the water-cooled fume hood control box. A rotating rod is fixedly connected to the outer right side of the rotating fan. The other end of the rotating rod passes through the filter screen. A scraper is rotatably connected to the middle of the water-cooled fume hood control box, and the scraper is rotatably connected to the filter screen. A partition is fixedly connected to the middle of the inner wall of the water-cooled fume hood control box, and a vent is opened on the front side of the outer wall of the partition. A water storage tank is fixedly connected to the lower middle part of the inner wall of the water-cooled fume hood control box, and a water inlet pipe is connected to the bottom of the water storage tank. A water pump is fixedly connected to the other end of the water inlet pipe. A delivery pipe is connected to the left side of the water pump. Atomizing nozzles are connected to the left and right sides of the bottom of the outer wall of the delivery pipe. A filtration mechanism is provided at the top of the inner wall of the water-cooled fume hood control box.

[0006] The above technical solution involves a motor installed inside the protective casing. Upon startup, this motor drives a rotating fan, which not only promotes airflow within the control box, thus facilitating heat dissipation, but also ensures proper airflow and maintains efficient heat dissipation within the control box. The scraper, in close contact with the filter screen, removes dust, oil, and other impurities adsorbed on the screen as it rotates, preventing clogging and protecting the filter. This also helps protect other electrical components from oil contamination. A water tank stores water for dust suppression and fume treatment using the water-cooled fume hood. An inlet pipe connects the water tank to a water pump, which draws water from the tank and delivers it through a conveying pipe to the atomizing nozzles. These nozzles evenly atomize the water into fine particles, spraying them inside the fume hood. Inside the fume hood, the atomized water comes into full contact with the rising fumes, allowing particulate matter in the fumes to be adsorbed by the water. Some water-soluble harmful substances also dissolve in the water, achieving initial purification and cooling of the fumes, reducing environmental pollution and damage to ventilation ducts.

[0007] As a further description of the above technical solution:

[0008] The filtration mechanism includes two oil-absorbing plates. The outer walls of the two oil-absorbing plates are fixedly connected to the left and right sides of the outer wall of the water-cooled fume hood control box. Filter plates are fixedly connected to the upper left and right sides of the outer wall of the water-cooled fume hood control box. Fixing blocks are fixedly connected to the bottom of the two filter plates. Scrapers are slidably connected to the inner walls of the two fixing blocks. Scrapers are slidably connected to the filter plates. An oil fume purifier is fixedly connected to the top of the inner wall of the water-cooled fume hood control box. An oil leakage plate is provided on the rear side of the partition. An oil storage tank is fixedly connected to the rear bottom of the inner wall of the water-cooled fume hood control box. A smoke extraction pipe is connected to the rear side of the oil fume purifier. A fan is fixedly connected to the other end of the smoke extraction pipe.

[0009] The above technical solution consists of two oil-absorbing plates and two filter plates. The oil-absorbing plates initially absorb grease from the fumes, while the filter plates further filter out solid particles and other impurities. A scraper plate can slide within a fixed block to regularly clean the filter plates, preventing clogging and ensuring consistent filtration. The fume purifier is installed on the top inner wall of the water-cooled fume hood control box to deeply purify the pre-filtered fumes, removing fine particles and harmful gases. A fan is connected to the fume purifier via a suction pipe, providing power for the intake and exhaust of fumes, ensuring smooth flow and eventual discharge of fumes throughout the system. Waste oil separated from the fume purifier flows down the drain plate behind the partition and slides into the oil storage tank, facilitating centralized treatment and preventing oil contamination of other internal components or disruption of equipment operation.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the fan is provided with a second protective shell. The left and right sides of the outer wall of the second protective shell are fixedly connected with connecting pieces one. The bottom of the two connecting pieces one is threadedly connected to the top rear side of the water-cooled fume hood control box one.

[0012] The above technical solution provides physical protection for the fan, preventing dust, oil, and impurities from entering the fan and avoiding performance degradation or even damage due to foreign object accumulation. At the same time, the second protective shell can reduce the impact of external collisions on the fan to a certain extent, playing a buffering and protective role. The first connecting piece serves as the connecting component between the second protective shell and the water-cooled fume hood control box, and the two are stably assembled through a threaded connection. This connection method facilitates installation, disassembly, and adjustment, and makes it convenient for subsequent maintenance and repair of the fan and related components.

[0013] As a further description of the above technical solution:

[0014] The outer wall of the water-cooled fume hood control box is fixedly connected with multiple connecting columns, and the bottom of each of the multiple connecting columns is fixedly connected with a support column.

[0015] The above technical solution involves evenly distributing the control box and support columns around the outer wall of the water-cooled fume hood control box, thus uniformly transferring the weight of the control box to the support columns. This also helps to mitigate vibrations caused by the operation of internal equipment, preventing deformation or damage to the control box shell due to uneven local stress. The control box directly contacts the ground or installation foundation, providing the main support force. Its structural design must consider load-bearing capacity, stability, and adaptability to different ground conditions. The support columns should have sufficient strength and rigidity to prevent the control box from tilting, shaking, or sinking during use.

[0016] As a further description of the above technical solution:

[0017] The bottom front and rear sides of the water storage tank are fixedly connected with connecting pieces two, and the outer right side of the two connecting pieces two is threadedly connected to the lower right side of the inner right side of the water fume hood control box one.

[0018] The above technical solution requires that the key connecting components between the water storage tank and the water fume hood control box have a structure and installation method that ensures the connection is firm and stable, can effectively transmit force, and prevents the water storage tank from shifting, shaking, or falling off under various working conditions. At the same time, it should also take into account the ease of installation and disassembly to facilitate subsequent maintenance of the water storage tank.

[0019] As a further description of the above technical solution:

[0020] The upper and lower ends of the right side of the outer wall of the water-cooled fume hood control box are rotatably connected to rotating doors. The upper and lower ends of the left side of the outer walls of the two rotating doors are fixedly connected to connecting blocks. The outer walls of the two connecting blocks are fixedly connected to pull rods.

[0021] The above technical solution involves a rotating connection between the rotating door and the right side of the outer wall of the water fume hood control box. This allows the rotating door to rotate around a specific axis, enabling it to open and close. The design of the rotating axis should ensure smooth and stable rotation, reduce frictional resistance and wear, and extend service life. The connecting block is fixed to the upper and lower ends of the left side of the rotating door's outer wall. The pull rod facilitates the operator's application of force, allowing the opening and closing of the rotating door to be controlled by pulling or pushing the pull rod, making operation more labor-saving and convenient.

[0022] As a further description of the above technical solution:

[0023] A controller is fixedly connected to the top front side of the outer wall of the water-cooled fume hood control box, and the controller is electrically connected to the water pump and the motor respectively.

[0024] The above technical solution establishes a reliable electrical connection between the controller, water pump, and motor. Through the transmission of control signals, it is possible to precisely control the start and stop of the water pump, the speed adjustment, and the operation and speed regulation of the motor. This enables dynamic adjustment of key parameters such as the water supply atomization volume and heat dissipation air volume of the water fume hood, adapting to the oil fume treatment needs under different cooking intensities and environmental conditions.

[0025] As a further description of the above technical solution:

[0026] A switch valve is fixedly connected to the outer wall of the delivery pipe, and the switch valve is electrically connected to the water pump.

[0027] The above technical solution enables the switch valve and the water pump to work together through electrical connection, automatically adjusting the water supply status according to system needs. For example, the switch valve is opened in a timely manner when the water pump starts and closed under specific conditions to prevent water waste and equipment damage from idling, thus realizing intelligent control of the entire water supply system.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the rotation of the motor and the rotating fan achieves heat dissipation inside the control box, which can effectively remove the heat generated by the electrical components during operation, avoiding the performance degradation and shortened life of the electrical components or even failure due to excessive temperature. The scraper cleans the filter screen in real time, which effectively prevents the filter screen from being blocked by the accumulation of dust, oil and impurities, ensuring that air can continuously and smoothly enter the control box and maintain a stable and efficient heat dissipation effect.

[0030] 2. In this utility model, the filter plate can adsorb and separate the grease components in the oil fume before it enters the control box, effectively reducing the burden on subsequent purification stages, improving the purification efficiency of the entire oil fume treatment system, significantly reducing the oil content of the oil fume entering the oil fume purifier, allowing the oil fume purifier to focus more on the treatment of fine particulate matter and harmful gases, thereby improving the overall purification effect, ensuring that the emitted oil fume meets strict environmental protection standards, and reducing pollution to the atmospheric environment.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of an improved structure for a water-cooled fume hood control box in an oil fume treatment device. The structure includes a water-cooled fume hood control box 1 and a scraper 8. A protective shell 3 is fixedly connected to the bottom left side of the outer wall of the water-cooled fume hood control box 1. A motor 4 is fixedly connected to the inner right side of the protective shell 3. A rotating fan 5 is fixedly connected to the output end of the motor 4. A filter screen 6 is fixedly connected to the bottom left side of the inner wall of the water-cooled fume hood control box 1. A rotating rod 7 is fixedly connected to the outer right side of the rotating fan 5. The other end of the rotating rod 7 passes through the middle of the filter screen 6 and is rotatably connected to... Scraper 8 is rotatably connected to filter screen 6. A partition 9 is fixedly connected to the middle of the inner wall of the water-cooled fume hood control box 1. A vent 10 is opened on the front side of the outer wall of the partition 9. A water storage tank 15 is fixedly connected to the lower middle part of the inner wall of the water-cooled fume hood control box 1. A water inlet pipe 12 is connected to the bottom of the water storage tank 15. A water pump 11 is fixedly connected to the other end of the water inlet pipe 12. A conveying pipe 13 is connected to the left side of the water pump 11. Atomizing nozzles 14 are connected to the bottom left and right sides of the outer wall of the conveying pipe 13. A filter mechanism 2 is provided on the top of the inner wall of the water-cooled fume hood control box 1.

[0040] Specifically, after motor 4 starts, it drives the rotating fan 5 at the output end to rotate. When the rotating fan 5 rotates, it causes outside air to enter the water-cooled fume hood control box 1 through filter screen 6, which can remove the heat generated by the electrical components inside the control box, thereby realizing the heat dissipation function inside the control box. While the rotating fan 5 is rotating, the rotating rod 7 on the right side of its outer wall also rotates. The rotating rod 7 passes through the middle of filter screen 6 and is rotatably connected to scraper 8, so that scraper 8 rotates on the surface of filter screen 6. Scraper 8 is in close contact with filter screen 6. When scraper 8 rotates... When the pump 8 rotates, it can scrape off the dust, oil, and impurities adsorbed on the surface of the filter screen 6, preventing the filter screen 6 from becoming clogged due to the accumulation of impurities, ensuring that air can continuously and smoothly enter the control box, and maintaining good heat dissipation. When the water pump 11 is working, it draws water from the water storage tank 15 through the water inlet pipe 12. The water drawn by the water pump 11 is transported through the delivery pipe 13 to the atomizing nozzles 14 on the left and right sides of the bottom of the outer wall of the delivery pipe 13. The atomizing nozzles 14 atomize the water evenly into tiny particles. These tiny atomized water particles are sprayed inside the water-cooled fume hood. In the water-cooled fume hood, the atomized water comes into full contact with the rising oil fumes, so that the particulate matter in the oil fumes is adsorbed by the water, and some water-soluble harmful substances are also dissolved in the water, thereby achieving preliminary purification and cooling of the oil fumes, reducing the pollution of the environment caused by oil fume emissions and the damage to ventilation ducts.

[0041] Reference Figure 1 , Figure 4 and Figure 5The filtration mechanism 2 includes two oil suction plates 201. The outer walls of the two oil suction plates 201 are fixedly connected to the upper left and right sides of the outer wall of the water-cooled fume hood control box 1. Filter plates 202 are fixedly connected to the left and right sides of the outer wall of the water-cooled fume hood control box 1. Fixing blocks 203 are fixedly connected to the bottom of the two filter plates 202. Scrapers 204 are slidably connected to the inner walls of the two fixing blocks 203. Scrapers 204 are slidably connected to the filter plates 202. An oil fume purifier 205 is fixedly connected to the top of the inner wall of the water-cooled fume hood control box 1. An oil leakage plate 208 is opened on the rear side of the partition 9. An oil storage tank 209 is fixedly connected to the rear side of the bottom of the inner wall of the water-cooled fume hood control box 1. A smoke extraction pipe 206 is connected to the rear side of the oil fume purifier 205. A fan 207 is fixedly connected to the other end of the smoke extraction pipe 206.

[0042] Specifically, under the suction force of the fan 207, the fumes first pass through the filter plates 202 on the upper left and right sides of the outer wall of the water-cooled fume hood control box 1. When the fumes pass through, the grease components are adsorbed by the filter plates 202, thus separating the grease from the fumes. The grease is adsorbed on the surface of the filter plates 202. The operator then uses the scraper 204 on the bottom fixing block 203 of the filter plates 202 to scrape off the grease adhering to the surface of the filter plates 202. The fumes after passing through the filter plates 202 are then drawn off by the suction... After the oil plate 201, the oil enters the water-cooled fume hood control box 1. The suction of the air 207 draws the oil fumes from the water-cooled fume hood control box 1 into the oil fume purifier 205. Some of the oil fumes will be adsorbed on the surface of the oil fume purifier 205. The oil fumes will fall downwards due to gravity and land on the oil drain plate 208 behind the partition 9. The oil fumes will then slowly flow into the oil storage tank 209 through the angle on the oil drain plate 208, realizing the collection of waste oil for subsequent centralized treatment and preventing oil pollution from causing pollution to other internal components of the equipment or affecting the operation of the equipment.

[0043] Reference Figure 2 , Figure 4 and Figure 5 The outer wall of the fan 207 is provided with a protective shell 2 16. The left and right sides of the outer wall of the protective shell 2 16 are fixedly connected with connecting pieces 1 17. The bottom of the two connecting pieces 1 17 is threadedly connected to the top rear side of the water-cooled fume hood control box 1. Multiple connecting columns 18 are fixedly connected to the outer wall of the water-cooled fume hood control box 1. The bottom of the multiple connecting columns 18 is fixedly connected with a support column 19. The bottom front and rear sides of the water storage tank 15 are fixedly connected with connecting pieces 2 20. The right side of the outer wall of the two connecting pieces 2 20 is threadedly connected to the lower right side of the inner wall of the water-cooled fume hood control box 1.

[0044] Specifically, during operation, the fan 207 is easily affected by external environmental factors. The protective shell 2 16 surrounds the outer wall of the fan 207 and can play a physical isolation role, preventing dust, oil and impurities from entering the fan. The connecting piece 1 17 serves as the connecting component between the protective shell 2 16 and the water fume hood control box 1 1, and the two are fixed together by a threaded connection. During installation, align the threaded hole at the bottom of connecting piece 17 with the corresponding mounting structure on the top rear side of the water fume hood control box 1, then screw in the bolts and tighten them to securely install the protective shell 16 onto the control box. The connecting columns 18 are evenly distributed around the outer wall of the control box, transferring the weight of the control box and various forces generated during operation to the support columns 19. The support columns 19 are in direct contact with the ground or mounting foundation, ensuring that the entire control box can be stably placed in the corresponding position. Align the connecting piece 20 with the corresponding threaded structure on the inner wall of the water fume hood control box 1, screw in the bolts and tighten them to complete the installation. When maintenance is required on the water storage tank 15, such as cleaning internal dirt and checking for leaks, the water storage tank 15 can be easily removed from the control box for maintenance by loosening the bolts in the reverse direction.

[0045] Reference Figure 1 , Figure 3 and Figure 4 The upper and lower right sides of the outer wall of the water-cooled fume hood control box 1 are rotatably connected to rotating doors 21. The upper and lower left sides of the outer walls of the two rotating doors 21 are fixedly connected to connecting blocks 22. The outer walls of the two connecting blocks 22 are fixedly connected to pull rods 23. The top front side of the outer wall of the water-cooled fume hood control box 1 is fixedly connected to a controller 24, which is electrically connected to the water pump 11 and the motor 4 respectively. The outer wall of the conveying pipe 13 is fixedly connected to a switch valve 25, which is electrically connected to the water pump 11.

[0046] Specifically, the rotating door 21 is rotatably connected to the right side of the outer wall of the water-cooled fume hood control box 1, allowing the rotating door 21 to rotate around a specific axis. The connecting block 22 is fixed to the upper and lower ends of the left side of the rotating door 21, providing a stable mounting base for the pull rod 23. When the rotating door 21 needs to be opened, the operator holds the pull rod 23 and applies pulling or pushing force. Due to the lever principle, the force is transmitted to the rotating door 21 through the connecting block 22, causing the rotating door 21 to rotate around the axis, thereby realizing the opening action. The controller 24 can receive signals from various sources. The controller 24 receives signals from the temperature sensor, liquid level sensor, and oil fume concentration sensor, and then precisely drives and adjusts the water pump 11 and motor 4 according to the preset control logic. The switch valve 25 is fixedly connected to the outer wall of the delivery pipe 13 and electrically connected to the water pump 11. The two work together to precisely control the water supply process of the water fume hood. When the water pump 11 starts, the controller 24 will send an opening signal to the switch valve 25 at the same time. The switch valve 25 opens according to the signal instruction, so that the water pumped by the water pump 11 can flow smoothly through the delivery pipe 13 to the atomizing nozzle 14.

[0047] Working Principle: After the motor 4 starts, it drives the rotating fan 5 at the output end to rotate, thereby realizing the heat dissipation function inside the control box. While the rotating fan 5 rotates, the rotating rod 7 on the right side of its outer wall also rotates. The rotating rod 7 passes through the middle of the filter screen 6 and is rotatably connected to the scraper 8, causing the scraper 8 to rotate on the surface of the filter screen 6. The scraper 8 is in close contact with the filter screen 6. When the scraper 8 rotates, it can scrape off the dust, oil, and impurities adsorbed on the surface of the filter screen 6, preventing the filter screen 6 from becoming clogged due to the accumulation of impurities. This ensures that air can continuously and smoothly enter the control box, maintaining good heat dissipation. (Water pump...) When working, water is drawn from the water storage tank 15 through the water inlet pipe 12. The water drawn by the water pump 11 is transported through the delivery pipe 13 to the atomizing nozzles 14 on the left and right sides of the bottom of the outer wall of the delivery pipe 13. The atomizing nozzles 14 atomize the water evenly into tiny particles. These tiny atomized water particles are sprayed inside the water-cooled fume hood. In the water-cooled fume hood, the atomized water comes into full contact with the rising oil fumes, so that the particulate matter in the oil fumes is adsorbed by the water, and some water-soluble harmful substances are also dissolved in the water, thereby achieving preliminary purification and cooling of the oil fumes, reducing the pollution of the environment and the damage to the ventilation ducts caused by oil fume emissions.

[0048] Furthermore, under the suction force of the fan 207, the fumes first pass through the filter plates 202 on the upper left and right sides of the outer wall of the water-cooled fume hood control box 1. When the fumes pass through, the grease components are adsorbed by the filter plates 202, thus achieving the separation of grease from the fumes. The grease is adsorbed on the surface of the filter plates 202. The operator uses the scraper 204 on the bottom fixing block 203 of the filter plate 202 to move the scraper 204 to scrape off the fumes adhering to the surface of the filter plate 202. The fumes after passing through the filter plates 202 are then drawn off by the suction... After the oil plate 201, the oil enters the water-cooled fume hood control box 1. The suction of the fan 207 draws the oil fumes from the water-cooled fume hood control box 1 into the oil fume purifier 205. Some of the oil fumes will be adsorbed on the surface of the oil fume purifier 205. The oil fumes will fall downwards due to gravity and land on the oil drain plate 208 behind the partition 9. The oil fumes will then slowly flow into the oil storage tank 209 through the angle on the oil drain plate 208, realizing the collection of waste oil for subsequent centralized treatment and avoiding oil pollution to other internal components of the equipment or affecting the operation of the equipment.
