Description
Technical Field
[0001] The utility model relates to the technical field of oil fume purification, in particular to an oil fume purification device and oil fume equipment. Background Art
[0002] In order to reduce oil fume pollution, it is usually necessary to use an oil fume purification device to purify the oil fume. Commonly used oil fume purification devices include: mechanical oil fume purification devices, water mist spray oil fume purification devices and electrostatic oil fume purification devices.
[0003] The working principle of the electrostatic fume purification device is that when the airflow enters the high-voltage ionization zone of the electric field, the air is quickly ionized under the action of the high-voltage electrostatic field, and its positive and negative ion flows can capture the fume particles, making them positively and negatively charged. The charged fume particles move toward the positive and negative plates of the electric field under the action of the electric field force and airflow in the electric field adsorption zone, are collected on the plates, and flow to the oil collection tray under the action of their own gravity.
[0004] Long-term use will form a layer of oil on the surface of the plate, making the electric field between the plates uneven. In severe cases, it will cause breakdown discharge, which greatly reduces the purification efficiency. The formed oil stains have high viscosity and are difficult to clean. Existing oil fume purification electric fields mostly require manual cleaning, which is time-consuming and labor-intensive, and has high maintenance costs. The simple mechanical scraper cleaning method is easy to cause wear to the plate during the scraper movement, reducing the service life of the plate. Utility Model Content

[0036] See also Figures 1 to 6 An embodiment of the utility model provides an oil fume purification device, including a purification component and a cleaning component. The purification component includes an adsorption portion 11, and the adsorption portion 11 includes at least two parallel and spaced electrode plates 111, and an adsorption channel 112 is formed between adjacent electrode plates 111; the cleaning component includes a cleaning member 21 and a driving mechanism 22, and the driving mechanism 22 can drive the cleaning member 21 to move along the adsorption channel 112, and at least part of the cleaning member 21 has elasticity so that the cleaning member 21 abuts against the two electrode plates in the adsorption channel 112.
[0037] The cleaning member 21 is driven by the driving mechanism 22 to move along the adsorption channel 112, and the cleaning member 21 abuts against the two pole plates 111 in the adsorption channel 112 to clean the oil stains on the surface of the pole plates 111, without manual cleaning, thereby reducing maintenance costs; at least part of the cleaning member 21 is elastic, which, on the one hand, enables the cleaning member 21 to abut against the pole plates 111 to ensure the cleaning effect, and on the other hand, can prevent the cleaning member 21 from causing wear to the surface of the pole plates 111, thereby ensuring the service life of the pole plates 111, and can also prevent the cleaning member 21 from getting stuck with the pole plates 111, thereby allowing the cleaning member 21 to move smoothly.
[0038] At least part of the cleaning member 21 is elastic so that the cleaning member 21 has a relaxed state and a compressed state. The cleaning member 21 is in a relaxed state outside the adsorption channel 112 , and is in a compressed state inside the adsorption channel 112 to abut against the two electrode plates 111 .
[0039] Specifically, the cleaning member 21 includes a support portion 211 and a cleaning portion 212, wherein the support portion 211 is connected to the driving mechanism 22, and the cleaning portions 212 are distributed on opposite sides of the support portion 211 to clean two plates 111 at the same time; the cleaning portion 212 is elastic, and / or the support portion 211 is elastic. The cleaning portion 212 may be a brush, a scraper, a blade, or other components capable of cleaning the plates 111.
[0040] In this embodiment, the cleaning portion 212 is elastic. The cleaning member 21 is in a relaxed state outside the adsorption channel 112, that is, the cleaning portion 212 is in a freely extended state, and the cleaning member 21 is in a compressed state inside the adsorption channel 112, that is, the cleaning portion 212 is elastically deformed under the pressure of the two electrode plates 111 so that the cleaning portion 212 abuts against the electrode plates 111.
[0041] The distance between the two electrode plates 111 is set to D. It can be understood that, in the expanded state, the width of the cleaning member 21 is greater than D, so that the cleaning member 21 is compressed when entering the adsorption channel 112 .
[0042] The outer surface of the cleaning member 21 is provided with a protruding structure 213. When the cleaning member 21 is located in the adsorption channel 112, the protruding structure 213 abuts against the electrode plate 111. Specifically, the protruding structure 213 is provided on the surface of the cleaning portion 212 away from the supporting portion 211. By providing the protruding structure 213, the contact area between the cleaning member 21 and the electrode plate 111 is reduced, and the friction force when the cleaning member 21 moves is reduced. The protruding structure 213 can be an arc-shaped protrusion, which, on the one hand, allows the cleaning member 21 to form a line contact with the electrode plate 111 to reduce the friction force, and on the other hand, it can prevent the cleaning member 21 from causing wear on the electrode plate 111.
[0043] When the cleaning member 21 is outside the adsorption channel 112, the width of the position where the protrusion structure 213 is located is greater than the distance between the two electrode plates 111. Since the cleaning member 21 is elastic, it is squeezed when entering the adsorption channel 112, so that the width of the position where the protrusion structure 213 is located is reduced, thereby achieving the abutment between the protrusion structure 213 and the electrode plate 111. Since the protrusion structure 213 protrudes to the outside of the cleaning member 21, in the expanded state, the width of the cleaning member 21 is the width of the position where the protrusion structure 213 is located, and in the expanded state, the width of the position where the protrusion structure 213 is located is greater than the distance between the two electrode plates 111.
[0044] Both ends of the cleaning member 21 are provided with guide structures 214, which guide the cleaning member 21 into the adsorption channel 112, and the width of the end of the cleaning member 21 is smaller than the spacing between the two electrode plates 111. By providing the guide mechanism at the end of the cleaning member 21, the width of the end of the cleaning member 21 is smaller than the spacing between the two electrode plates 111, so that the cleaning member 21 can smoothly enter the adsorption channel 112. The guide structure 214 can be an inclined surface, a curved surface, a wedge-shaped portion or an arc-shaped portion.
[0045] In this embodiment, the width of the guide structure 214 at the location gradually increases from the end to the middle of the cleaning member 21 to guide the cleaning member 21 to gradually enter the adsorption channel 112. When the cleaning member 21 is located outside the adsorption channel 112, the maximum width D1 at the location of the guide structure 214 is greater than or equal to the distance D between the two electrode plates 111, and the minimum width D2 at the location of the guide structure 214 is less than the distance D between the two electrode plates 111. When the cleaning member 21 is located outside the adsorption channel 112, since the minimum width at the location of the guide structure 214 is less than the distance between the two electrode plates 111, it is convenient for the guide structure 214 to smoothly enter the adsorption channel 112. Since the maximum width at the location of the guide structure 214 is greater than or equal to the distance between the two electrode plates 111, the guide structure 214 can be squeezed when the cleaning member 21 enters the adsorption channel 112, so that the cleaning member 21 is squeezed, driving the width at the location of the protruding structure 213 to decrease, thereby realizing that the protruding structure 213 enters the adsorption channel 112 and abuts against the electrode plates 111.
[0046] By providing guide structures 214 at both ends of the cleaning member 21, the cleaning member 21 can reciprocate along the adsorption channel 112 to achieve two-way cleaning, improve cleaning efficiency and avoid cleaning dead corners. Optionally, the electrode plate 111 extends in a vertical plane to facilitate the downward flow of oil stains on the electrode plate 111, so that the cleaning member 21 moves in a vertical direction. The cleaning member 21 can enter and exit the adsorption channel 112 from the upper end or the lower end of the adsorption channel 112. When not cleaning, the cleaning member 21 is usually stopped above the adsorption channel 112. Specifically, the guide structure 214 is provided at both ends of the cleaning portion 212, that is, the upper end and the lower end of the cleaning portion 212 are provided with a guide structure 214, which facilitates the cleaning member 21 to enter the adsorption channel 112 from top to bottom or from bottom to top.
[0047] In the present embodiment, the cleaning member 21 includes two cleaning sheets 2121 arranged at intervals, each cleaning sheet 2121 is used to clean one electrode plate 111, and guide structures 214 are provided at both ends of the cleaning sheet 2121. Specifically, the cleaning portion 212 includes two cleaning sheets 2121, and the two cleaning sheets 2121 are distributed on opposite sides of the support portion 211. Since the cleaning portion 212 is elastic, that is, the cleaning sheet 2121 is an elastic sheet. Guide structures 214 are provided at both ends of the cleaning sheet 2121. It can be understood that in the diastolic state, the maximum width at the position of the guide structure 214 is greater than or equal to the distance between the two electrode plates 111, and the minimum width at the position of the guide structure 214 is less than the distance between the two electrode plates 111, so that the guide structure 214 can smoothly enter the adsorption channel 112.
[0048] It can be that the ends of the two cleaning sheets 2121 are close to each other to form a curved surface or an inclined surface as the guide structure 214. It can also be that the ends of the two cleaning sheets 2121 are close to each other, and the end of each cleaning sheet 2121 is folded outward to form a wedge-shaped portion as the guide structure 214. The ends of the two cleaning sheets 2121 are close to each other, so that in the diastolic state, the distance between the ends of the two cleaning sheets 2121 is less than the spacing between the two pole plates 111, which facilitates the guide structure 214 to smoothly enter the adsorption channel 112. Since the ends of the cleaning sheets 2121 are folded outward to form a wedge-shaped portion, the folding setting can prevent the cleaning sheets 2121 from causing wear to the pole plates 111. In the diastolic state, the maximum width at the location of the wedge-shaped portion is greater than the distance between the two pole plates 111, which facilitates the guide structure 214 to be squeezed when entering the adsorption channel 112.
[0049] The angle θ between the outer surface of the wedge-shaped portion and the end surface of the cleaning member 21 is an acute angle, that is, both ends of the cleaning member 21 are bent toward the middle direction, which is more convenient for entering the adsorption channel 112, and the sharp corners of the wedge-shaped portion can be rounded.
[0050] In this embodiment, the guide structure 214 and the protrusion structure 213 exist at the same time, that is, the two ends of the cleaning member 21 are provided with the guide structure 214, and the outer surface of the cleaning member 21 is provided with the protrusion structure 213, and the protrusion structure 213 can abut against the electrode plate 111. Specifically, the cleaning portion 212 of the cleaning member 21 includes two cleaning sheets 2121 arranged at intervals, the outer surface of the cleaning sheet 2121 is provided with the protrusion structure 213, and the two ends of the cleaning sheet 2121 are provided with the guide structure 214.
[0051] When entering the adsorption channel 112, the guide structure 214 enters the adsorption channel 112 first, and then the protruding structure 213 enters the adsorption channel 112. Since when the cleaning member 21 is located outside the adsorption channel 112, the maximum width of the guide structure 214 is greater than or equal to the distance between the two electrode plates 111, and the minimum width of the guide structure 214 is less than the distance between the two electrode plates 111, when entering the adsorption channel 112, the guide structure 214 is squeezed, driving the width of the protruding structure 213 to decrease, so as to smoothly enter the adsorption channel 112 between the two electrode plates 111, and after entering the adsorption channel 112, the protruding structure 213 abuts against the electrode plates 111.
[0052] In some embodiments, in order to reduce friction, in the relaxed state, the width of the protrusion structure 213 at the location is greater than the maximum width of the guide structure 214 at the location, so that when the cleaning member 21 moves in the adsorption channel 112, the guide structure 214 is spaced apart from the electrode plate 111, while the protrusion structure 213 abuts against the electrode plate 111.
[0053] The cleaning assembly also includes a slide bar 23, on which a cleaning member 21 is disposed, and a driving mechanism 22 can drive the slide bar 23 to move, the slide bar 23 extending in a direction perpendicular to the electrode plate 111, and the position of the cleaning member 21 on the slide bar 23 is adjustable. The slide bar 23 supports the cleaning member 21. One cleaning member 21 can be disposed on one slide bar 23, or multiple cleaning members 21 can be disposed side by side, and the multiple cleaning members 21 can clean multiple adsorption channels 112 simultaneously.
[0054] Specifically, the cleaning member 21 is sleeved on the slide bar 23, and the slide bar 23 is provided with limit blocks 24 on both sides of the cleaning member 21. The two limit blocks 24 clamp the cleaning member 21, and the position of the limit blocks 24 on the slide bar 23 is adjustable. By adjusting the limit blocks 24, the position of the cleaning member 21 on the slide bar 23 can be adjusted, usually the position of the cleaning member 21 is fine-tuned within a small range. Once the spacing between adjacent plates 111 changes slightly, the position of the cleaning member 21 can be adjusted by adjusting the limit blocks 24.
[0055] The limit block 24 may be threadedly connected to the slide bar 23, so that the position of the limit block 24 can be changed and the limit block 24 can be locked on the slide bar 23 to stabilize the position of the cleaning member 21. Alternatively, the limit block 24 itself is elastic, and the limit block 24 has an inner hole to be sleeved on the slide bar 23, and the inner diameter of the inner hole is smaller than the outer diameter of the slide bar 23, and the limit block 24 is elastically deformed to be pressed against the slide bar 23.
[0056] In this embodiment, the cleaning member 21 moves linearly along the adsorption channel 112. Optionally, the electrode plate 111 extends in a vertical plane to facilitate the downward flow of oil on the electrode plate 111. When cleaning is not required, the cleaning member 21 stops above the adsorption channel 112. Each time cleaning is performed, the cleaning member 21 can move back and forth along the adsorption channel 112, so that after cleaning, the cleaning member 21 stops above the adsorption channel 112. Each time cleaning is performed, the cleaning member 21 can move back and forth once, or at least twice. Therefore, the driving mechanism 22 only needs to be able to complete linear motion. In other embodiments, the cleaning member 21 can also move horizontally and vertically, thereby driving the cleaning member 21 to move in a larger range.
[0057] The driving mechanism 22 can be a cylinder, a hydraulic cylinder or a screw mechanism, as long as it can achieve linear movement. In this embodiment, the driving mechanism 22 includes a motor, a screw 221 and a slider, the motor is used to drive the screw to rotate, the slider is threadedly connected to the screw, the slide bar 23 is fixed to the slider, and the rotation of the screw drives the slider to move along the screw, so that the slide bar 23 moves.
[0058] It can be that a set of driving mechanisms 22 is provided, the driving mechanism 22 is provided at one end of the slide rod 23, and a guide mechanism is provided at the other end of the slide rod 23, and the guide mechanism is used to guide the slide rod 23. The guide mechanism includes a guide rod and a guide block, the guide block is slidably connected to the guide rod, and the slide rod 23 is fixedly connected to the guide block. When the slide rod 23 moves along the lead screw 221, the guide block slides along the guide rod.
[0059] Alternatively, two groups of driving mechanisms 22 are provided, and the two groups of driving mechanisms 22 are spaced apart and distributed on the slide bar 23 . The two groups of driving mechanisms 22 start and stop synchronously to drive the slide bar 23 to move.
[0060] The oil fume purification device also includes a box body 41, and the purification component and the cleaning component are both arranged in the box body 41. The box body 41 is provided with a smoke inlet for the oil fume to flow in and a smoke outlet for the oil fume to flow out. The purification component is arranged on the oil fume flow path to facilitate the oil fume to flow into the adsorption channel 112. The box body 41 is also provided with an ionization part, which is located upstream of the adsorption part 11 along the direction of the flue gas flow, and forms an ionization area by ionizing the air. When the flue gas passes through the ionization area, the oil fume particles are charged.
[0061] The oil fume purification device further includes an oil receiving pan 42 , which is disposed at the bottom of the box body 41 . The oil receiving pan 42 is disposed opposite to the adsorption portion 11 , so that the oil on the electrode plate 111 can flow into the oil receiving pan 42 .
[0062] In some embodiments, the support portion 211 is elastic. In the expanded state, the width of the cleaning member 21 is greater than the distance D between the two electrode plates 111. When the cleaning member 21 enters the adsorption channel 112, the cleaning portion 212 is in contact with the electrode plate 111 and is compressed. Since the support portion 211 is elastic, the cleaning portion 212 is in full contact with the electrode plate 111 and will not scratch the electrode plate 111.
[0063] In the expanded state, the width of the end of the cleaning member 21 is smaller than the distance between the two electrode plates 111 , so that the cleaning member 21 can smoothly enter the adsorption channel 112 .
[0064] Optionally, the purification component includes a power module, which supplies power to the adsorption part 11 , and an adsorption channel 112 is formed between adjacent plates 111 . When the power module supplies power to the plates 111 , oil stains can be adsorbed by the plates 111 .
[0065] When cleaning is required, the start and stop of the driving mechanism can be controlled manually, for example, by pressing a button. Alternatively, the oil fume purification device includes a main control module 31 and a detection module, the power module and the driving mechanism 22 are both connected to the main control module 31, the detection module is used to obtain detection information and send the detection information to the main control module 31, the main control module 31 determines the cleaning time according to the detection information, and can automatically determine the cleaning time, so that the cleaning is timely and not too frequent, reducing maintenance costs, and ensuring purification efficiency and safety. By cleaning the pole plates 111 in a timely manner, a stable electric field between the pole plates 111 is ensured, sparking is avoided, and the electric field strength is ensured to avoid fire.
[0066] The oil fume purification device further includes a control box 43, and the main control module 31 and the detection module can be arranged in the control box 43. When the driving mechanism 22 is started, it can drive the cleaning member 21 to move along the adsorption channel 112. When the cleaning member 21 moves in the adsorption channel 112, it cleans the surface of the electrode plate 111 to clean the oil stains on the surface of the electrode plate 111, without manual cleaning, thereby reducing maintenance costs.
[0067] The specific usage process is as follows: when powered on, the detection module obtains detection information in real time, and the main control module 31 determines whether the cleaning mode needs to be executed based on the detection information; when executing the cleaning mode, the main control module 31 first cuts off the power supply module, and then starts the driving mechanism 22, the driving mechanism 22 drives the cleaning member 21 to move along the adsorption channel 112, and the cleaning member 21 cleans the surface of the electrode plate 111; after the cleaning mode ends, the driving mechanism 22 drives the cleaning member 21 to move to the outside of the adsorption channel 112, and the main control module 31 cuts off the power supply to the driving mechanism 22.
[0068] Optionally, the electrode plate 111 extends in a vertical plane to facilitate the downward flow of oil on the electrode plate 111. When cleaning is not required, the cleaning member 21 stops above the adsorption channel 112. Each time the cleaning mode is executed, the cleaning member 21 can reciprocate along the adsorption channel 112, so that after the cleaning mode ends, the cleaning member 21 stops above the adsorption channel 112. Each time the cleaning mode is executed, the cleaning member 21 can reciprocate once or at least twice. In this embodiment, each time the cleaning mode is executed, the cleaning member 21 reciprocates three times along the adsorption channel 112, and the cleaning mode ends.
[0069] The detection information includes three parameters, namely electrical parameters, sound signals and cleaning cycles. When at least one of the three parameters does not meet the set conditions, the cleaning mode is executed. By detecting three parameters and making triple judgments, reliability is improved and missed judgments and misjudgments are reduced.
[0070] The electrical parameters include the voltage and current of the power module. When one of the voltage and current exceeds the corresponding set range, it is judged that the set condition is not met, and the cleaning mode is executed. The detection module includes a voltage acquisition component and a current acquisition component, which are used to obtain the voltage and current. When the voltage exceeds the first set range and / or the current exceeds the second set range, the cleaning mode is executed.
[0071] When foreign matter or oil accumulates on the plate 111, arcing and sparking will occur, which will affect the electric field strength and may cause fire. When sparking, a "pop" and "pop" sound is emitted. The detection module includes a sound sensor, which is used to obtain sound signals.
[0072] In some embodiments, if the sound signal exceeds the corresponding set range and continues for a set time, it is judged that the set condition is not met, and the cleaning mode is executed. For example, if the sound signal exceeds the corresponding set range and lasts for more than 1 minute, the cleaning mode is executed. In some embodiments, if the sound signal exceeds the corresponding set range and repeatedly appears more than a first set number of times within a first set time, it is judged that the set condition is not met, and the cleaning mode is executed. For example, if the sound signal exceeds the corresponding set range and repeatedly appears more than 30 times within 30 minutes, the cleaning mode is executed.
[0073] The cleaning cycle refers to the working time of the oil fume purification device since the last execution of the cleaning mode. If the cleaning cycle reaches the preset time, the cleaning mode will be executed. After each execution of the cleaning mode, the working time of the oil fume purification system is accumulated. If the working time reaches the preset time, the cleaning mode will be executed. The size of the cleaning cycle can be set in the program as needed.
[0074] After each cleaning mode is executed, the verification mode is executed. The purpose of executing the verification mode is to verify whether the abnormal parameters are normal after this cleaning. Specifically, when executing the verification mode, the main control module 31 powers on the power module, and the main control module 31 determines whether the cleaning mode needs to be executed based on the detection information. If so, the cleaning mode is executed or the alarm device is triggered. Otherwise, the oil fume purification device is controlled to operate normally. The main control module 31 determines whether the cleaning mode needs to be executed based on the detection information. If so, it means that the cleaning effect is not good this time and the cleaning mode needs to be executed again.
[0075] If the main control module 31 determines that the cleaning mode still needs to be executed based on the detection information after executing the cleaning mode for many times, it means that there may be some faults, for example, the cleaning member 21 is damaged, and the cleaning member 21 is not tightly abutted against the electrode plate 111, resulting in poor cleaning effect. Therefore, when executing the verification mode, if the main control module 31 determines that the cleaning mode needs to be executed based on the detection information, it is determined whether the cleaning mode has been executed continuously for a set number of times. If so, the power supply module is powered off and the alarm device is triggered. Otherwise, the cleaning mode is executed again. The set number of times can be two, three or more than three times.
[0076] The main control module 31 is used to control the above-mentioned electrical components, including but not limited to power modules, sound sensors, voltage acquisition components, current acquisition components, motors, etc. The main control module 31 is an Intel processor, an AMD processor, a PLC controller, an ARM processor or a single-chip microcomputer, and is also used with a motherboard, a memory stick, a storage medium and a power supply. The power supply is AC power or a lithium battery. When a display screen is provided, a display card is also provided. Other automated controls and electrical components not mentioned are all knowledge well known to those skilled in the art and will not be described here.
[0077] The embodiment of the utility model also provides a range hood device, comprising a range hood body and the above-mentioned range hood purification device, wherein the range hood purification device is arranged on the flow path of the smoke. The range hood device can be a range hood, an integrated stove, and the like.
