Description

Technical Field

[0001] The invention relates to the technical field of oil fume purification devices, and in particular to a novel and efficient oil fume purification device. Background Art

[0002] The fine and loose black soot deposited by incomplete combustion of oil substances can be used to make ink, printing ink, etc. The oil smoke we usually emit when cooking is a large amount of thermal oxidation decomposition products produced by cooking oil and food under high temperature conditions. When cooking, the oil is heated. When the temperature reaches the smoking point of cooking oil, 170°C, blue smoke appears at the initial decomposition. As the temperature continues to rise, the decomposition speed accelerates. When the temperature reaches 250°C, a large amount of oil smoke appears, accompanied by a pungent smell. The particle size of the oil smoke is between 0.01 microns and 0.3 microns. The relevant departments have analyzed the oil smoke samples collected from residents' homes that often fry food, and a total of more than 220 chemical substances have been detected, including aldehydes, ketones, hydrocarbons, fatty acids, alcohols, aromatic compounds, esters, lactones, heterocyclic compounds, etc. Known mutagenic carcinogens such as volatile nitrosamines are also found in cooking oil smoke.

[0003] After filtering the oil fume, the existing oil fume purification device will have a large amount of grease attached to the filter. After long-term use, the filter will be clogged, thereby affecting the efficiency of extracting the oil fume. Therefore, the filter needs to be regularly removed and cleaned to ensure the normal operation of the oil fume purification device. However, removing the filter is rather troublesome and requires professional maintenance personnel to operate. Summary of the invention

[0007] By adopting the above technical scheme, the first air inlet duct and the second air inlet duct are separated, so that when one of the air inlet ducts is cleaning the filter, the other air inlet duct can filter the oil fume normally, thereby achieving uninterrupted operation and ensuring the purification effect of the oil fume; when the filter is cleaned, the filter is cleaned by the cooperation of the partition and the cleaning component, and the cleaning waste liquid is collected in the waste liquid collection box. No manual operation is required throughout the process, reducing the labor intensity of filter disassembly and cleaning.

[0008] Preferably, a rubber layer is provided on the surface of the baffle.

[0009] By adopting the above technical solution and setting a rubber pad, the baffle can be prevented from direct contact and wear with the inner walls of the first air inlet pipe and the second air inlet pipe, while also improving the sealing effect of the baffle on the first air inlet pipe and the second air inlet pipe, thereby preventing the cleaning waste liquid from leaking from the gap.

[0010] Preferably, the cleaning assembly includes a cover plate arranged above the partition and used to seal the first air inlet duct orifice or the second air inlet duct orifice, a first atomizing nozzle is arranged on the lower surface of the cover plate, a hollow connecting rod is connected to one end of the cover plate, the connecting rod is connected to the first atomizing nozzle, the connecting rod is vertically arranged directly above the partition, and the connecting rod rotation seal passes through the top of the outer shell, a support frame is arranged on the outer shell, a drive motor connected to the connecting rod is installed on the support frame, the upper end of the connecting rod is connected to a suction hose, the suction hose is connected to a purification liquid storage tank, a booster pump is arranged on the purification liquid storage tank, and the drive motor and the booster pump are connected to the processor.

[0011] By adopting the above technical solution, a driving motor is set to enable the cover plate to rotate around the connecting rod, thereby realizing the blocking of the first air inlet duct or the second air inlet duct. The first atomizing nozzle set on the cover plate can flush the filter in the first air inlet duct or the second air inlet duct with purification liquid, thereby realizing the cleaning operation of the filter; at the same time, the connecting rod is located at the upper end of the main air inlet duct, and when the oil smoke moves upward, the heat will be transferred to the connecting rod, and the purification liquid passing through the connecting rod will be heated to a certain temperature, thereby improving the cleaning effect of grease on the filter.

[0012] Preferably, both sides of the support frame are connected with limit plates, the limit plates are provided with contact switches connected to the processor, and the connecting rod is connected with a blocking rod cooperating with the contact switch.

[0013] By adopting the above technical solution, contact switches are arranged on both sides of the support frame to limit the rotation range of the connecting rod, and the cover plate is accurately rotated to above the first air inlet pipe or the second air inlet pipe to ensure normal cleaning work.

[0014] Preferably, a collecting tank located between the exhaust pipe and the main air inlet duct is provided in the outer shell, and an oil fume purification component is installed in the collecting tank. The oil fume purification component is connected to a liquid inlet pipe, and the liquid inlet pipe is connected to a purified liquid storage tank. The bottom of the collecting tank is connected to a drain pipe, and a water stop valve is installed on the drain pipe.

[0015] By adopting the above technical solution, a fume purification component is provided to purify the fume using a purification liquid during the movement of the fume from the first air inlet pipe or the second air inlet pipe into the exhaust pipe, thereby further increasing the purification effect of the fume. The collection tank and the drain pipe collect the generated waste liquid for subsequent treatment, thereby reducing the pollution of the waste liquid.

[0016] Preferably, the bottom of the collecting tank is inclined toward the drain pipe.

[0017] By adopting the above technical solution, the inclined collecting tank can make the waste liquid flow toward the drain pipe, ensuring that all the waste liquid is discharged from the collecting tank, and avoiding the waste liquid from accumulating in the collecting tank and corroding the collecting tank and the outer shell for a long time.

[0018] Preferably, the oil fume purification component includes a mounting plate that blocks the channel for the oil fume to move toward the exhaust pipe, the mounting plate is provided with a plurality of through holes, a plurality of second atomizing nozzles are arranged on the mounting plate, the second atomizing nozzles are connected to connecting pipes, and the connecting pipes are connected to the liquid inlet pipe.

[0019] By adopting the above technical solution, the mounting plate blocks the channel for the oil smoke to move toward the exhaust pipe, and a through hole is opened on the mounting plate so that the oil smoke can only pass through the through hole. In addition, the purification liquid sprayed by the second atomizing nozzle is also sprayed from the through hole, so that the oil smoke and the purification liquid are mixed, thereby achieving purification of the oil smoke.

[0020] Preferably, card slots are provided on both sides of the partition, and a buckle assembly for clamping the filter is provided on the side of the first air inlet pipe and the second air inlet pipe away from the card slots, and the buckle assembly includes a first groove provided on the inner walls of the first air inlet pipe and the second air inlet pipe, and a first spring is provided in the first groove, and the first spring is connected to a buckle, and the buckle includes an upper clamp arm and a lower clamp arm, and the length of the upper clamp arm is greater than the length of the lower clamp arm.

[0021] By adopting the above technical solution, the filter can be installed in the first air inlet duct and the second air inlet duct through the cooperation of the set card slot and the buckle assembly, which is convenient for installation and disassembly; when the buckle of the buckle assembly is installed, since the length of the upper clamp arm is greater than the length of the lower clamp arm, the upper clamp arm still protrudes from the inner wall of the pipe when the lower clamp arm of the filter is pressed back into the first groove, so that the filter can be directly pressed against the upper clamp arm and the pressed buckle can be released to achieve the installation of the filter. The operation is simple and the installation can be quickly completed.

[0022] Preferably, a sealing assembly is provided on the inner wall of the upper end of the opening, and the sealing assembly includes a second groove, a second spring is connected in the second groove, and the second spring is connected to a fitting block extending out of the second groove and in contact with the baffle.

[0023] By adopting the above technical solution, due to the elastic effect of the second spring, the fitting block is forced to always keep in contact with the baffle, thereby filling the gap between the baffle and the upper end of the opening, preventing external oil smoke from entering the cleaning area during cleaning to affect the cleaning effect and the waste liquid from leaking from the gap to cause waste liquid pollution. In addition, compared with the problem of poor sealing effect caused by long-term wear and tear due to direct fixed contact sealing treatment, the present invention can always maintain sealing performance, greatly increasing practicality.

[0024] Preferably, a protective plate is provided in the second groove and is gap-matched with the inner wall of the second groove. The second spring is connected to the protective plate. A limiting protrusion is provided on the inner wall of the second groove, and the limiting protrusion is located below the protective plate. A pressure sensor wirelessly connected to the processor is installed on the side of the protective plate away from the second spring.

[0025] By adopting the above technical solution, when the baffle rotates, the pressure sensor will be squeezed through the fitting block, the second spring and the protective plate. The pressure sensor senses the changes in the pressure value in real time and transmits the data to the processor. When the baffle rotates to fit the inner walls of the first air inlet pipe and the second air inlet pipe, when the pressure sensed by the pressure sensor reaches the set value, the processor controls the self-locking motor to stop moving, so as to prevent the baffle from continuing to rotate and causing extrusion and deformation of the inner wall of the pipe.

[0026] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects:

[0027] 1. By separating the first air inlet duct and the second air inlet duct, when one of the air inlet ducts is cleaning the filter, the other air inlet duct can filter the oil fume normally, so as to achieve uninterrupted operation and ensure the purification effect of the oil fume; when cleaning the filter, the filter is cleaned by the cooperation of the partition and the cleaning component, and the cleaning waste liquid is collected in the waste liquid collection box. No manual operation is required throughout the process, which reduces the labor intensity of filter disassembly and cleaning.

[0028] 2. The rubber pad is provided to prevent the baffle from direct contact and wear with the inner walls of the first air inlet pipe and the second air inlet pipe, and also improves the sealing effect of the baffle for the first air inlet pipe and the second air inlet pipe, thereby preventing the waste liquid from cleaning from leaking out from the gap.

[0029] 3. By setting a driving motor, the cover plate can rotate around the connecting rod, so as to achieve the blocking of the first air inlet pipe or the second air inlet pipe. The first atomizing nozzle arranged on the cover plate can flush the filter in the first air inlet pipe or the second air inlet pipe with the purification liquid, so as to achieve the cleaning operation of the filter. At the same time, the connecting rod is located at the upper end of the main air inlet duct. When the oil smoke moves upward, the heat will be transferred to the connecting rod, and the purification liquid passing through the connecting rod will be heated to a certain temperature, thereby improving the cleaning effect of grease on the filter.

[0030] 4. By setting contact switches on both sides of the support frame, the rotation range of the connecting rod is limited, and the cover plate is accurately rotated to above the first air inlet pipe or the second air inlet pipe to ensure the normal cleaning work.

[0031] 5. During the movement of oil smoke from the first air inlet pipe or the second air inlet pipe into the exhaust pipe, an oil smoke purification component is provided to purify the oil smoke using a purification liquid, thereby further increasing the purification effect of the oil smoke. The collection tank and the drain pipe collect the generated waste liquid for subsequent treatment, thereby reducing the pollution of the waste liquid.

[0032] 6. The inclined collection tank can make the waste liquid flow toward the drain pipe, ensuring that all the waste liquid is discharged from the collection tank, and avoiding the waste liquid from accumulating in the collection tank for a long time and corroding the collection tank and the outer shell.

[0033] 7. The installation plate blocks the passage for the oil smoke to move toward the exhaust pipe, and a through hole is opened on the installation plate so that the oil smoke can only pass through the through hole. In addition, the purification liquid sprayed from the second atomizing nozzle is also sprayed from the through hole, so that the oil smoke and the purification liquid are mixed to achieve purification of the oil smoke.

[0034] 8. The filter can be installed in the first air inlet duct and the second air inlet duct by cooperating with the provided card slot and the card buckle assembly, which is convenient for installation and disassembly; when the card buckle of the card buckle assembly is installed on the filter, since the length of the upper clamp arm is greater than the length of the lower clamp arm, the upper clamp arm still protrudes from the inner wall of the pipe when the lower clamp arm of the filter is pressed back into the first groove, so that the filter can be directly pressed against the upper clamp arm and the pressed buckle can be released to achieve the installation of the filter. The operation is simple and can be installed quickly.

[0035] 9. Due to the elastic effect of the second spring, the fitting block is forced to always keep in contact with the baffle, thereby filling the gap between the baffle and the upper end of the opening, preventing external oil smoke from entering the cleaning area during cleaning to affect the cleaning effect and the cleaning waste liquid from leaking from the gap to cause waste liquid pollution. In addition, compared with the problem of poor sealing effect after long-term wear caused by direct fixed contact sealing treatment, the present invention can always maintain sealing performance, greatly increasing practicality.

[0036] 10. When the baffle rotates, the pressure sensor will be squeezed through the fitting block, the second spring and the protective plate. The pressure sensor senses the changes in the pressure value in real time and transmits the data to the processor. When the baffle rotates to fit the inner walls of the first air inlet pipe and the second air inlet pipe, when the pressure sensed by the pressure sensor reaches the set value, the processor controls the self-locking motor to stop moving to prevent the baffle from continuing to rotate and causing extrusion and deformation of the inner wall of the pipe.

The purification liquid storage tank 18 is provided with a booster pump 19, and the driving motor 16 and the booster pump 19 are connected to the processor. The connecting rod 25 is preferably made of a metal material with good thermal conductivity, which is convenient for heating the purification liquid (the purification liquid is alkaline solution). The lower surface of the cover plate 7 is rotatably connected to the partition plate 11 , which further increases the stability of the cover plate 7 .

[0055] Limiting plates 14 are connected to both sides of the support frame 13 , and contact switches 29 connected to the processor are arranged on the limiting plates 14 . A blocking rod 15 matched with the contact switch 29 is connected to the connecting rod 25 .

[0056] A collecting tank 24 is provided in the outer shell 8 and is located between the exhaust pipe 21 and the main air inlet pipe. A fume purification component 26 is installed in the collecting tank 24. The fume purification component 26 is connected to a liquid inlet pipe 20. The liquid inlet pipe 20 is connected to the purified liquid storage tank 18. The bottom of the collecting tank 24 is connected to a drain pipe 27, and a water stop valve is installed on the drain pipe 27.

[0057] The bottom of the collecting tank 24 is inclined toward the drain pipe 27 .

[0062] A power detection device is provided in the suction pump 22, and the power detection device is connected to an alarm light 23. The power detection device monitors the power of the suction pump 22. When it is detected that the power of the suction pump 22 increases, it indicates that the filter 28 has been clogged. The alarm light 23 is controlled to flash to remind the operator to clean the filter 28 in time to ensure the normal operation of the oil fume purification device.

[0063] Working principle: When one of the first air inlet duct 10 and the second air inlet duct 12 is performing the oil fume extraction work, the other one is performing the cleaning work (in this embodiment, the first air inlet duct 10 is selected to perform the cleaning work for description). The self-locking motor 32 is controlled to rotate, and the baffle 4 is driven to rotate into the first air inlet duct 10. The baffle 4 squeezes the pressure sensor 601 during the rotation process. The pressure sensor 601 transmits data to the processor in real time. When the pressure reaches the set value, the self-locking motor 32 is controlled to stop rotating. At this time, the baffle 4 seals the pipeline of the first air inlet duct 10; the driving motor 16 is controlled to rotate, driving the connecting rod 25 and the cover plate 7 to rotate; when the baffle rod 15 contacts the contact switch 29, the driving motor 16 is controlled to stop rotating through the processor, and at this time the cover plate 7 reaches the top of the first air inlet duct 10 and blocks the upper port of the first air inlet duct 10.

[0064] At the same time, the suction pump 22 and the booster pump 19 are turned on. The negative pressure generated by the suction pump 22 draws the oil smoke from the second air inlet pipe 12, passes through the filter screen 28, and then passes through the through hole 2603 on the mounting plate 2601. The booster pump 19 increases the pressure in the purified liquid storage tank 18, forcing the purified liquid to be pumped out from the suction hose 17 and the liquid inlet pipe 20. The purified liquid is sprayed from the second atomizing nozzle 2604 through the liquid inlet pipe 20 to mix with the oil smoke, thereby purifying the oil smoke. The purified oil smoke falls into the collection tank 24 due to gravity for collection. The final waste liquid can be discharged from the drain pipe 27 at a fixed time. The purified oil smoke is discharged through the exhaust pipe 21. The purified liquid is sprayed from the first atomizing nozzle 3 through the suction hose 17 to clean the filter screen 28 below. The cleaned waste liquid enters the waste liquid collection tank 1 through the manifold 2.

[0065] When the second air inlet duct 12 needs to be cleaned, the driving motor 16 and the self-locking motor 32 are controlled to reverse, so as to adjust the positions of the cover plate 7 and the baffle plate 4, and then the subsequent cleaning operation can be carried out.

[0066] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
