Description

Technical Field

[0001] This utility model relates to the field of oil fume treatment, and in particular to an electrostatic oil fume processor. Background Technology

[0002] In the catering industry and various cooking scenarios that generate oil fumes, the issue of oil fume emissions has always been a key focus of environmental governance and health protection. Oil fumes not only contain a large amount of pollutants such as grease and particulate matter, which can cause serious pollution to the atmospheric environment, but also pose potential health hazards to the human respiratory system, cardiovascular system, and other systems.

[0003] Existing electrostatic fume treatment methods typically involve charging the fume particles, which are then adsorbed onto an adsorption plate under the influence of an electric field, thus purifying the fume. However, during use, the adsorption plates on current equipment gradually accumulate grease on their surface after adsorbing a large number of fume particles. This reduces the adsorption capacity of the plates, affecting the overall purification effect of the electrostatic fume processor. Manual disassembly and cleaning of the adsorption plates is required, which is cumbersome, time-consuming, and labor-intensive, impacting cleaning efficiency.

[0004] Therefore, it is necessary to design an electrostatic fume processor that can electrostatically treat oil fumes, then move the shielding frame to block them while simultaneously moving the spray cleaning liquid to clean the adsorption plate, preventing liquid from entering the exhaust pipe, eliminating the need for disassembly and cleaning, and improving the purification effect. Utility Model Content

[0005] To overcome the shortcomings of current equipment where the adsorption plates accumulate oil and grease on their surface after adsorbing a large number of oil fume particles, leading to a decrease in adsorption capacity and affecting the overall purification effect of the electrostatic oil fume processor, and requiring manual disassembly and cleaning of the adsorption plates, which is cumbersome, time-consuming, labor-intensive, and inefficient, this utility model provides an electrostatic oil fume processor that can simultaneously clean the adsorption plates with a moving shield after electrostatic treatment of the oil fumes, preventing liquid from entering the exhaust pipe, eliminating the need for disassembly and improving the purification effect.

[0006] The technical implementation scheme of this utility model is as follows:

[0007] An electrostatic precipitator for cooking fumes includes a fume hood, a smoke exhaust pipe, a fan, an ionizer, a mounting rack, adsorption plates, a shielding assembly, and a cleaning assembly. The smoke exhaust pipe is connected to the upper side of the fume hood, and the fan is connected to the front of the smoke exhaust pipe. The ionizer is slidably engaged at the upper front of the smoke exhaust pipe. The mounting rack is connected to the smoke exhaust pipe, and multiple adsorption plates are connected to the mounting rack. A shielding assembly for shielding the adsorption plates during cleaning is provided between the smoke exhaust pipe and the mounting rack. The mounting rack is provided with a cleaning assembly for cleaning the adsorption plates.

[0008] In addition, it is particularly preferred that the device also includes a filter screen, with the filter screen slidably engaged at both the lower front and rear parts of the chimney.

[0009] Furthermore, it is particularly preferred that the shielding assembly includes a sliding plate, a first motor, a gear, a rack, a transmission assembly, a common lead screw, and a shielding frame. The sliding plate is slidably connected to the upper part of the placement frame, the first motor is connected to the rear right side of the placement frame, the gear is connected to the output shaft of the first motor, the rack is connected to the rear side of the sliding plate, and the rack and gear mesh with each other. The common lead screw is rotatably connected to the rear right side of the smoke outlet, a transmission assembly is provided between the upper part of the common lead screw and the output shaft of the motor, and the shielding frame is threadedly connected to the common lead screw. The shielding frame is slidably connected to the placement frame and the smoke outlet.

[0010] Furthermore, it is particularly preferred that the transmission assembly includes pulleys and a flat belt, with pulleys connected to both the upper part of the ordinary lead screw and the output shaft of the motor, the pulleys on the output shaft of the motor being located above the gears, and a flat belt being wound between the pulleys.

[0011] Furthermore, it is particularly preferred that the cleaning assembly includes a second motor and a spray frame. The second motor is connected to the front right side of the placement frame. A reciprocating screw is provided on the output shaft of the second motor. The reciprocating screw is rotatably connected to the placement frame. The spray frame is threadedly connected to the reciprocating screw, and the spray frame is in contact with the placement frame.

[0012] Furthermore, it is particularly preferred that the device also includes a water outlet and a control valve, with the water outlet connected to the lower side of the placement rack and the control valve connected to the water outlet.

[0013] This utility model has the following advantages: 1. This utility model allows oil fumes to enter the fume hood. Through the operation of the ionizer, the oil mist particles are ionized and charged, then flow through the adsorption plate for adsorption. They are then moved out by the sliding plate, and at the same time, they are blocked by the moving shield frame. Then, the moving spray frame sprays cleaning liquid to clean the adsorption plate. This allows the oil fumes to be electrostatically treated. After the moving shield frame blocks the fumes, the moving spray cleaning liquid cleans the adsorption plate, preventing liquid from entering the exhaust pipe. No disassembly and cleaning are required, thus improving the purification effect.

[0014] 2. This utility model allows for the removal and cleaning of the filter screen and ionizer by pulling them apart. Then, the new or cleaned filter screen and ionizer are picked up and brought into contact with the flue. The filter screen and ionizer are then pushed to install them. This allows for the installation of the filter screen for multiple filtration of oil fumes while simultaneously installing the ionizer. This facilitates the installation, removal, cleaning, and maintenance of the filter screen and ionizer, improving maintenance efficiency. Attached Figure Description

[0022] An electrostatic precipitator for cooking fumes, such as Figures 1-5 As shown, the device includes a fume hood 1, a smoke exhaust duct 2, a fan 3, a filter screen 4, an ionizer 5, a placement rack 6, adsorption plates 7, a water outlet 8, a control valve 9, a shielding assembly, and a cleaning assembly. The smoke exhaust duct 2 is connected to the upper side of the fume hood 1. The fan 3 is connected to the front of the smoke exhaust duct 2. The filter screen 4 is slidably engaged at both the lower front and rear of the smoke exhaust duct 2 to facilitate the filtration of impurities or particulate matter. The ionizer 5 is slidably engaged at the upper front of the smoke exhaust duct 2. The placement rack 6 is connected to the smoke exhaust duct 2. Six adsorption plates 7 are connected to the placement rack 6. The water outlet 8 is connected to the lower side of the placement rack 6. The control valve 9 is connected to the water outlet 8. A shielding assembly is provided between the smoke exhaust duct 2 and the placement rack 6 to shield the adsorption plates 7 during cleaning. A cleaning assembly is provided on the placement rack 6 to clean the adsorption plates 7.

[0023] like Figure 1 , Figure 4 and Figure 5As shown, the shielding assembly includes a sliding plate 10, a first motor 11, a gear 12, a rack 13, a transmission assembly 14, a lead screw 15, and a shielding frame 16. The sliding plate 10 is slidably connected to the upper part of the placement frame 6. The first motor 11 is connected to the rear right side of the placement frame 6. The gear 12 is connected to the output shaft of the first motor 11. The rack 13 is connected to the rear side of the sliding plate 10, and the rack 13 meshes with the gear 12. The rear right side of the smoke outlet 2 is rotatably connected to... The ordinary lead screw 15 has a transmission assembly 14 between its upper part and the output shaft of the motor. The transmission assembly 14 includes a pulley and a flat belt. The upper part of the ordinary lead screw 15 and the output shaft of the motor are both connected to pulleys. The pulley on the output shaft of the motor is located above the gear 12. A flat belt is wound between the pulleys. The shielding frame 16 is threadedly connected to the ordinary lead screw 15. The shielding frame 16 is slidably connected to the placement frame 6 and the smoke outlet 2.

[0024] like Figure 4 As shown, the cleaning assembly includes a second motor 17 and a spray frame 18. The second motor 17 is connected to the front right part of the placement frame 6. A reciprocating screw is provided on the output shaft of the second motor 17. The reciprocating screw is rotatably connected to the placement frame 6. The spray frame 18 is threadedly connected to the reciprocating screw, and the spray frame 18 is in contact with the placement frame 6.

[0025] This device can be used when kitchen cooking requires the treatment of cooking fumes. The exhaust duct 2 is installed on the wall. When cooking, the fan 3 is turned on, and the fumes are drawn into the fume hood 1 and flow into the exhaust duct 2. They are filtered by the filter screen 4 at the front. The fumes continue to flow, and the ionizer 5 operates to ionize and charge the oil mist particles into charged particles. These particles are blocked by the slide plate 10. Under the action of the electric field, the fumes flow through the adsorption plate 7 for adsorption and then through the filter screen 4 at the rear for filtration. Clean air is then discharged from the exhaust duct 2, thus electrostatically treating the fumes.

[0026] After use, turn off the fan 3 and the ionizer 5. When the adsorption plate 7 has been used for a long time and has absorbed a lot of oil fumes, start the first motor 11. The first motor 11 drives the gear 12 to rotate. The gear 12 meshes with the rack 13, causing the rack 13 to move and thus moving the slide plate 10 out. At the same time, it also drives the pulley to rotate, causing the flat belt to rotate and the ordinary lead screw 15 to rotate. Under the action of the thread, the shielding frame 16 moves to block. Then turn off the first motor 11. Next, the cleaning liquid is connected to the external spray frame 18, allowing the cleaning liquid to enter the spray frame 18 and spray onto the adsorption plate 7. Then start the second motor 17, which drives the reciprocating lead screw to rotate. Under the action of the thread, the spray frame 18 moves back and forth and sprays cleaning liquid to clean the adsorption plate 7. The wastewater generated from cleaning flows into the lower part of the placement frame 6. Then control the control valve 9 to open, allowing the wastewater to be discharged from the outlet 8.

[0027] The shielding frame 16 blocks and guides the wastewater, thereby electrostatically treating the fumes. Simultaneously, the shielding frame 16 moves to block the fumes while the spray cleaning liquid cleans the adsorption plate 7, preventing liquid from entering the exhaust pipe 2. This eliminates the need for disassembly and cleaning, improving the purification effect. After cleaning, the second motor 17 and the control valve 9 are turned off, and the spray frame 18 is disconnected from the cleaning liquid. Then, the first motor 11 reverses its operation, causing the gear 12 to rotate in the opposite direction. The gear 12 meshes with the rack 13, causing the rack 13 to move in the opposite direction, which in turn moves the slide plate 10 back to its original position. Simultaneously, the pulley rotates in the opposite direction, causing the flat belt to rotate in the opposite direction, which in turn causes the ordinary lead screw 15 to rotate in the opposite direction. Under the action of the screw, the shielding frame 16 moves in the opposite direction and returns to its original position. Then, the filter screen 4 and the ionizer 5 are pulled to move and remove them for cleaning and replacement.

[0028] Then, pick up the new or cleaned filter 4 and the ionizer 5 and bring them into contact with the smoke outlet 2. Then, push the filter 4 and the ionizer 5 to move and install them. This allows the filter 4 to perform multiple filtrations of the oil fumes while the ionizer 5 is installed. This facilitates the installation, removal, cleaning, and maintenance of the filter 4 and the ionizer 5, improving maintenance efficiency. Afterward, you can continue to use this device to treat the oil fumes.
