Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of integrated oil fume purification machines, and in particular to an electrostatic dust collection module for integrated oil fume purification machines. Background Technology
[0002] An electrostatic dust collection module is a core component that purifies oil fumes through the principle of electrostatic adsorption. It mainly consists of two parts: an ionization zone and a dust collection zone. When oil fumes pass through the equipment, they first enter the ionization zone. Under the action of a high-voltage electric field, oil mist particles, dust, and other pollutants in the oil fumes are ionized and charged. Subsequently, the charged particles enter the dust collection zone and are adsorbed onto the dust collection plate under the action of a strong electric field, thereby achieving the purpose of purifying oil fumes.
[0003] Currently, the high-voltage dust collection plates of electrostatic precipitators are usually fixedly and equidistantly distributed in the inner cavity of the integrated fume purification machine. During operation, charged oily fumes pass through the gaps between the dust collection plates and are adsorbed onto the plate surface by Coulomb force. However, since the spacing and angle of the existing dust collection plates are fixed, when the oil fume concentration is low and the air flow is small, the fixed large plate spacing will make the migration path of charged oily fume particles in the electric field longer. Some particles are swept away by the airflow and do not have enough time to be fully adsorbed before passing through the gaps between the dust collection plates and being discharged directly from the equipment, thereby reducing the adsorption and purification effect of oil fumes. Therefore, an electrostatic dust collection module for integrated fume purification machines is proposed. Utility Model Content
[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.
[0005] In view of the problems existing in the current electrostatic dust collection module of the integrated oil fume purification machine, this utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide an electrostatic dust collection module for an integrated oil fume purification machine. It is suitable for solving the problem that the spacing and angle of the existing dust collection plates are fixed. When the oil fume concentration is low and the air flow is small, the large spacing will cause charged oil fume particles to pass through the gaps in the dust collection plates before they can be fully adsorbed and directly discharged from the equipment, thereby reducing the oil fume adsorption and purification effect.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an electrostatic dust collection module for an integrated oil fume purification machine, comprising:
[0008] A range hood, wherein an exhaust pipe is fixedly connected to one side of the range hood;
[0009] An ionization module installed inside the range hood is used to ionize particles in the cooking fumes into negatively charged particles.
[0010] A dust collection module is installed inside the range hood. The dust collection module includes multiple dust collection plates positioned above the ionization module. Each dust collection plate is rotatably connected to the inner wall of the range hood via a connector. The dust collection module also includes a drive component for deflecting the multiple dust collection plates.
[0011] As a preferred embodiment of the electrostatic dust collection module for the integrated oil fume purification machine of this utility model, the ionization module includes two connecting plates fixedly connected to the inner wall of the oil fume hood, and multiple ionization plates for discharge are fixedly connected to the opposite surfaces of the two connecting plates.
[0012] As a preferred embodiment of the electrostatic dust collection module for the integrated oil fume purification machine of this utility model, the connecting member includes multiple rotating shafts rotatably connected to the inner wall of the oil fume hood. One end of each rotating shaft is fixed to a corresponding dust collection plate, and the other end of each rotating shaft rotatably penetrates the oil fume hood. A gear is fixedly sleeved at the penetrating end of each rotating shaft, and the multiple gears mesh sequentially.
[0013] As a preferred embodiment of the electrostatic dust collection module for the integrated oil fume purification machine of this utility model, the connecting member further includes a sealed bearing fixedly sleeved on each rotating shaft, and the outer wall of the oil fume machine is provided with a plurality of mounting holes that fit the sealed bearings, and the outer ring of each sealed bearing is fixed in the corresponding mounting hole.
[0014] In a preferred embodiment of the electrostatic dust collection module for an integrated fume purification machine described in this utility model, the driving component includes a protective cover fixedly connected to the side wall of the fume hood, a servo motor fixedly installed on one side of the protective cover, and the output shaft of the servo motor rotating through the protective cover and fixed to one of the rotating shafts.
[0015] As a preferred embodiment of the electrostatic dust collection module for the integrated oil fume purification machine described in this utility model, a gas flow meter is fixedly connected to one side of the oil fume machine, and the detection end of the gas flow meter is sealed and penetrates into the oil fume machine.
[0016] As a preferred embodiment of the electrostatic dust collection module for the integrated oil fume purification machine of this utility model, each dust collection plate has multiple guide grooves on both sides, and the guide grooves are inclined towards the center of the dust collection plate.
[0017] As a preferred embodiment of the electrostatic dust collection module for the integrated oil fume purification machine of this utility model, each dust collection plate is fixedly connected to a pair of connecting blocks on one side, and each pair of connecting blocks is fixedly connected to an inclined guide plate on one side, with a gap for air circulation left between the guide plate and the dust collection plate.
[0018] The beneficial effects of this utility model are as follows: When there is less oil fume, the drive component drives the dust collection plate to deflect through the connector, and the gap between adjacent dust collection plates is reduced accordingly, forming a denser electric field distribution area, so that the oil fume can fully contact the dust collection plate and its charged particles are adsorbed onto the dust collection plate, ensuring that the charged particles are efficiently adsorbed and improving the purification efficiency under low concentration oil fume conditions.

[0032] Example 1
[0033] Reference Figures 1-4 The first embodiment of this utility model provides an electrostatic dust collection module for an integrated oil fume purification machine, which can adjust the gap between adjacent dust collection plates to ensure that charged particles are efficiently adsorbed and improve the purification efficiency under low-concentration oil fume conditions. It includes: an oil fume hood 100, an ionization module 200 and a dust collection module 300.
[0034] Among them, an exhaust pipe 101 is fixedly connected to one side of the range hood 100;
[0035] An ionization module 200 is installed inside the range hood 100. The ionization module 200 is used to ionize the particles in the oil fumes into negatively charged particles.
[0036] The dust collection module 300 is installed inside the range hood 100. The dust collection module 300 includes multiple dust collection plates 301 installed above the ionization module 200. Each dust collection plate 301 is rotatably connected to the inner wall of the range hood 100 via a connector 302. The dust collection module 300 also includes a drive assembly 303 for deflecting the multiple dust collection plates 301.
[0037] The range hood 100 is equipped with a fan for air intake, and a smoke collection hood at the bottom of the range hood 100 is used to extract cooking fumes. A control panel is set on the front side of the smoke collection hood to control the operation of the entire device. When the range hood 100 is working, the cooking fumes first enter the ionization module 200 inside the range hood 100. Under the action of the ionization module 200, the particles in the cooking fumes are ionized into negatively charged particles. Subsequently, the charged particles rise to the dust collection module 300 located above the ionization module 200. The drive component 303 in the dust collection module 300 can drive multiple dust collection plates 301 to deflect through the connector 302 to adjust the spacing and angle between the dust collection plates 301, so that the negatively charged cooking fume particles can come into more full contact with the dust collection plates 301 under the action of the electric field force and be adsorbed onto the dust collection plates 301, thereby achieving full purification of the cooking fumes. The purified gas is finally discharged through the exhaust pipe 101.
[0038] Example 2
[0039] Reference Figure 2 and Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, the ionization module 200 includes two connecting plates 201 fixedly connected to the inner wall of the range hood 100. The opposing surfaces of the two connecting plates 201 are each fixedly connected to a plurality of ionization plates 202 for discharge.
[0040] Multiple ionization plates 202 are arranged parallel to each other between two connecting plates 201. The top and bottom of the ionization plates 202 are provided with serrated protrusions. These protrusions generate a tip discharge effect in the high-voltage electric field. After the ionization plates 202 are energized, a non-uniform electric field is formed between the multiple ionization plates 202, generating a corona discharge phenomenon, which ionizes the air into a large number of electrons and ions. When the oil fumes pass through this area, the particles collide with the electrons and ions and adsorb the charge, thus transforming into negatively charged particles.
[0041] Example 3
[0042] Reference Figures 2-3 This is the third embodiment of the present invention. Unlike the previous embodiment, the connector 302 includes multiple rotating shafts 302a rotatably connected to the inner wall of the range hood 100. One end of each rotating shaft 302a is fixed to the corresponding dust collection plate 301, and the other end of each rotating shaft 302a rotatably passes through the range hood 100. A gear 302b is fixedly sleeved on the through end of each rotating shaft 302a, and the multiple gears 302b mesh in sequence.
[0043] When any one of the rotating shafts 302a is driven to rotate by the drive component 303, it can drive other rotating shafts 302a to rotate through the meshing of gears 302b, thereby causing the corresponding dust collection plate 301 to deflect from the initial vertical state to an inclined state. The two adjacent gears 302b rotate in opposite directions, so that the two adjacent dust collection plates 301 are distributed in a V-shape or inverted V-shape combination, and the two adjacent dust collection plates 301 do not contact each other. This can shorten the interval between the two adjacent dust collection plates 301. When the amount of oil fume is small, it can effectively reduce the flow speed of oil fume in the area of dust collection plate 301, forcing charged oil fume particles to prolong their residence time in the enhanced electric field, thereby increasing the probability of contact between particles and the electrode plate.
[0044] The connector 302 also includes a sealed bearing 302c that is fixedly sleeved on each rotating shaft 302a. The outer wall of the range hood 100 has multiple mounting holes that fit the sealed bearings 302c, and the outer ring of each sealed bearing 302c is fixed in the corresponding mounting hole.
[0045] The sealed bearing 302c allows the rotating shaft 302a to rotate freely, and the sealing performance of the sealed bearing 302c prevents the oil fumes inside the range hood 100 from leaking through the rotating shaft 302a. At the same time, it reduces the frictional resistance when the rotating shaft 302a rotates, thereby improving the transmission reliability of the rotating shaft 302a.
[0046] In addition, the drive assembly 303 includes a protective cover 303a fixedly connected to the side wall of the range hood 100. A servo motor 303b is fixedly installed on one side of the protective cover 303a. The output shaft of the servo motor 303b rotates through the protective cover 303a and is fixed to one of the rotating shafts 302a.
[0047] The output shaft of the servo motor 303b drives one of the rotating shafts 302a to rotate, and through the meshing transmission of the gear set 302b, the power is synchronously transmitted to all rotating shafts 302a, realizing the synchronous deflection of multiple dust collection plates 301. The protective cover 303a provides physical protection for the gear set 302b to prevent dust from affecting the driving accuracy.
[0048] Example 4
[0049] Reference Figures 1-4 This is the fourth embodiment of the present utility model. Unlike the previous embodiment, a gas flow meter 304 is fixedly connected to one side of the range hood 100, and the detection end of the gas flow meter 304 is sealed and penetrates into the range hood 100.
[0050] The gas flow meter 304 is used to monitor the flow rate of the oil fume gas in real time. When the oil fume concentration changes and causes fluctuations in the gas flow rate, the gas flow meter 304 feeds the data back to the control system to provide data for the drive component 303 to adjust the deflection angle of the dust collection plate 301. When the amount of oil fume is large, the dust collection plate 301 remains vertical. When the amount of oil fume is small, the drive component 303 deflects the dust collection plate 301 to the corresponding tilt state.
[0051] In addition, each dust collection plate 301 has multiple guide grooves 305 on both sides, and the guide grooves 305 are inclined toward the center of the dust collection plate 301.
[0052] When the fumes pass through the dust collection area, the guide channel 305 guides the airflow to converge towards the center of the dust collection plate 301. This not only prolongs the residence time of charged particles in the strong electric field area, but also enhances the contact area between the particles and the surface of the guide channel 305, thereby improving the adsorption efficiency.
[0053] Each dust collection plate 301 has a pair of connecting blocks 306 fixedly connected to one side, and each pair of connecting blocks 306 has an inclined guide plate 307 fixedly connected to one side, with a gap for air circulation between the guide plate 307 and the dust collection plate 301.
[0054] A connecting block 306 and a guide plate 307 are provided between two adjacent dust collection plates 301 arranged in an inverted V shape. The inclined guide plate 307 can guide the oil fumes to the surface of the guide plate 307. Air can drift out through the gap between the dust collection plate 301 and the guide plate 307, thereby forcing more particles to come into contact with the surface of the dust collection plate 301 and be adsorbed. When the dust collection plate 301 is in a vertical state, the guide plate 307 still remains in an inclined state to promote the contact of particles with the surface of the dust collection plate 301.
[0055] During use, the smoke collection hood at the bottom of the range hood 100 absorbs the oil fumes, and the internal fan starts to draw in the oil fumes, introducing them into the equipment. When the oil fumes enter the ionization module 200, the serrated protrusions at the top and bottom of the ionization plate 202 generate a tip discharge effect under the high voltage electric field, causing the oil fume particles to collide with and adsorb the charge, turning them into negatively charged particles. At the same time, the gas flow meter 304 monitors the oil fume gas flow rate in real time and feeds the data back to the control system. When the amount of oil fumes is small, the control system controls the servo motor 303b, whose output shaft drives the fixed rotating shaft 302a to rotate, and through the gear 302b group, multiple rotating shafts 302a rotate together, thereby deflecting the dust collection plate 301 from a vertical position to an inclined position.
[0056] At this time, the adjacent dust collection plates 301 are distributed in a V-shape or inverted V-shape to shorten the plate spacing of the dust collection plates 301. After the negatively charged oil fume particles rise to the dust collection module 300, they move towards the dust collection plate 301 under the action of the electric field force. The guide grooves 305 on both sides of the dust collection plate 301 guide the airflow to converge towards the center of the dust collection plate 301 to prolong the residence time of the particles in the strong electric field area and increase the contact area between the particles and the surface of the guide grooves 305. At the same time, the guide plate 307 can guide the oil fume to the surface of the dust collection plate 301, forcing more particles to contact the dust collection plate 301 and be adsorbed. After the adsorption and purification of the gas, it is finally discharged from the equipment through the exhaust pipe 101.
[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
