Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and particularly to a waste gas filter for an essential oil eutectic reactor. Background Art

[0002] A waste gas filter for an essential oil eutectic reactor is a device used to treat the waste gas generated during the essential oil eutectic reaction process. During the production of essential oil eutectic, the components in the essential oil will form a microcrystalline structure at low temperature, and these components may crystallize at normal temperature, resulting in the release of volatile organic compounds. In addition, the solvents and other chemical substances used in the production process may also release volatile organic compounds during heating or other processes. Direct emission of volatile organic compounds has a certain impact on the environment and human health. Volatile organic compounds can pollute the air quality, affecting the ecological environment and human health. Long-term exposure to certain volatile organic compounds may cause problems such as headache, irritation of eyes, nose and throat, and allergic reactions. At present, after the activated carbon filter screen in the waste gas filter for the essential oil eutectic reactor is blocked, the amount of waste gas passing through the filter screen decreases, and the filter screen needs to be replaced frequently, causing many inconveniences during the production process and affecting production efficiency. Summary of the Invention

[0003] Based on this, it is necessary to provide a waste gas filter for an essential oil eutectic reactor to solve at least one of the above technical problems.

[0004] A waste gas filter for an essential oil eutectic reactor includes an essential oil eutectic reactor assembly, a waste gas cooling assembly, a waste gas filtering mechanism, and an impurity recovery assembly. An exhaust gas outlet is installed on the upper side wall of the essential oil eutectic reactor assembly. The waste gas cooling assembly includes an air inlet end, a cooling tank, and a cooling coil. One end of the air inlet end is fixedly connected to the exhaust gas outlet, and one end of the cooling tank is connected to the other end of the air inlet end. The cooling coil is wound around the side wall of the cooling tank. The waste gas filtering mechanism includes an exhaust pipe, a filtering tank, an air outlet, a driving fan assembly, a filtering assembly, a knocking and vibrating assembly, and a spring assembly. One end of the exhaust pipe is fixedly connected to the other end of the cooling tank, the bottom of the filtering tank is fixedly connected to the other end of the exhaust pipe, one end of the air outlet is fixedly connected to the top of the filtering tank, and the other end of the air outlet is fixedly connected to the end of the cooling coil adjacent to the essential oil eutectic reactor assembly. The driving fan assembly, the filtering assembly, the knocking and vibrating assembly, and the spring assembly are all installed inside the filtering tank. The driving fan assembly includes a driving fan and a transmission rod. The driving fan is installed inside the filtering tank, and the bottom of the driving fan is connected to the bottom of the filtering tank. The bottom of the transmission rod is connected to the top of the driving fan, and the top of the transmission rod rotatably passes through the bottom of the filtering assembly. The bottom of the filtering assembly is sleeved on the top of the transmission rod. The knocking and vibrating assembly is connected to the bottom of the filtering assembly, and the bottom of the spring assembly is connected to the top of the filtering assembly. The filtering assembly is slidably installed inside the filtering tank. The impurity recovery assembly is installed on the side wall of the filtering tank.

[0005] The filtering component is composed of activated carbon and can adsorb and remove volatile organic compounds and tiny essential oil crystals in the waste gas. The waste gas cooling component can cool the high-temperature waste gas generated during the eutectic reaction of essential oils to a certain extent. The driving fan component rotates to push the filtering component to shake up and down, making the impurities in the filtering component more evenly distributed and improving the filtering efficiency of the filtering component. The knocking and vibrating component knocks on the filtering tank to make the impurities accumulated on the filtering tank fall off, preventing the accumulation of impurities from affecting the filtering efficiency of the filtering tank. The spring component can fix the filtering component and control the shaking amplitude and direction of the filtering component. The impurity recovery component can adsorb the impurities shaken down by the knocking and vibrating component, improving the stability of the long-term operation of the entire filtering mechanism.

[0006] In one of the embodiments, the impurity recovery component includes an impurity recovery pipe, an impurity recovery tank, and an output pipe. The lower end of the impurity recovery pipe is fixedly connected to the side wall of the filtering tank, and the height of the lower end of the impurity recovery pipe is equal to the height of the middle part of the filtering component. The bottom of the impurity recovery tank is fixedly connected to the upper end of the impurity recovery pipe. The upper end of the output pipe is fixedly connected to the side wall of the filtering tank, and the upper end of the output pipe is located above the filtering component. The lower end of the output pipe is fixedly connected to the top of the impurity recovery tank.

[0007] In one of the embodiments, the essential oil eutectic reaction kettle component includes a kettle body, a transmission device, a stirrer, and a feed inlet. The kettle body is installed on the ground. The transmission device is installed on the top of the kettle body. The stirrer is installed inside the kettle body, and the upper end of the stirrer penetrates through the top of the kettle body. The top of the stirrer is connected to the transmission device. The feed inlet is installed on the top of the kettle body, and the waste gas discharge port is installed on the side wall of the kettle body.

[0008] In one of the embodiments, the filtering component includes a filter element, a square magnet piece, and a ring magnet. The filter element is slidably installed inside the filtering tank. The upper half of the square magnet piece is installed at the bottom of the filter element. The top of the ring magnet is fixedly abutted against the bottom of the square magnet piece, and the side wall of the ring magnet is fixedly connected to the inner side wall of the filtering tank. The square magnet piece and the ring magnet have opposite magnetic polarities.

[0009] In one of the embodiments, a cavity is formed inside the impurity recovery tank, and an impurity adsorbing member is installed inside the cavity. A sliding door is installed on the side wall of the impurity recovery tank.

[0010] In one of the embodiments, a through groove is formed in the middle part of the filtering component, and the through groove penetrates through the lower side wall of the filtering component. A clamping groove is formed on the upper side wall of the through groove, a spiral surface is formed on the bottom side wall of the clamping groove, and a positioning groove is formed on the bottom side wall of the through groove.

[0011] In one embodiment, a limiting block is installed on the side wall at the upper end of the transmission rod. The limiting block is clamped in the clamping groove. A fixing block is fixedly installed at the top of the transmission rod. The fixing block is clamped in the clamping groove, and a pushing rod is formed at the bottom of the fixing block. The pushing rod is located directly above the spiral surface. The top of the transmission rod is inserted into the through groove.

[0012] In one embodiment, the knocking and vibrating assembly includes four pulling rope members and four iron ball members. The tops of the four pulling rope members are all connected to the bottom of the filtering assembly, and the four iron ball members are respectively fixedly connected to the bottoms of the four pulling rope members.

[0013] In one embodiment, the spring assembly includes four spring members and a fixing plate. The bottoms of the four spring members are all connected to the top of the filtering assembly. The bottom of the fixing plate is connected to the tops of the four spring members, and the side wall of the fixing plate is fixedly connected to the inner wall of the filter tank.

[0014] In one embodiment, activated carbon is stored inside the filtering assembly. The driving fan includes a fixed shaft, a bearing and three fan blades. The bottom of the fixed shaft is fixedly connected to the bottom of the filter tank. The bearing is rotatably sleeved on the top of the fixed shaft. The top of the bearing is fixedly connected to the bottom of the transmission rod. The three fan blades are all connected to the side wall of the bearing at a certain inclination angle and at the same interval.

[0015] By adding an exhaust gas cooling component, the present invention can cool the high-temperature exhaust gas generated during the eutectic process of essential oil to a certain extent, providing the exhaust gas temperature most suitable for filtration for the subsequent exhaust gas filtering mechanism, improving the efficiency of exhaust gas filtration and reducing the damage of some components of the exhaust gas filtering mechanism caused by excessive temperature.

[0016] By setting up the driving fan assembly, after long-term use, when the filter element becomes blocked, the impact pressure of the exhaust gas on the bottom of the filter element increases. The exhaust gas pushes the filter element upward. The square magnet piece at the bottom of the filter element separates from the annular magnet fixed on the inner wall of the filter tank. And the filter element compresses the spring assembly upward under the force, causing the clamping groove to move upward synchronously, and the limiting block disengages from the clamping groove, releasing the restriction on the transmission rod. The driving fan rotates counterclockwise under the blowing of the exhaust gas at the bottom. The driving fan drives the bearing to rotate, and the transmission rod rotates following the bearing. And when the transmission rod rotates, it drives the pushing rod to rotate. The pushing rod moves from the lowest point of the spiral surface to the highest point of the spiral surface, and this repeats. When the pushing rod pushes the spiral surface to move, the spiral surface causes the filter element to shake up and down. During the up-and-down shaking of the filter element, the solid impurities attached to the bottom of the filter element will fall off during the shaking, making the impurities adsorbed by the activated carbon more evenly distributed. The activated carbon inside the filter element will also be redistributed evenly, so that the filter element is unclogged again and part of the filtering effect is restored. When the filtering effect of the filter element is partially restored, the filter element will move downward under the action of its own gravity and the weight of the iron ball. When the filter element moves downward to a certain position, under the magnetic attraction of the square magnet piece and the annular magnet, the square magnet piece and the annular magnet will adsorb together until the limiting block is restricted by the clamping groove again, and the driving fan assembly stops working. This extends the service life of the filter element, reduces the time cost and labor cost of frequently replacing the filter element, and enables the entire filter to operate stably for a long time.

[0017] By setting up the knocking and vibrating assembly, when the pushing rod pushes the spiral surface to move, the spiral surface causes the filter element to shake up and down. The filter element drives the knocking and vibrating assembly at the bottom to shake. The iron ball piece continuously knocks on the transmission rod and the inside of the filter tank during the shaking, causing the impurities adsorbed on the transmission rod and the inner wall of the filter tank to fall off due to the vibration generated by the knocking. This avoids the accumulation of impurities on the transmission rod, which may cause the transmission rod to lose its function, and also avoids the accumulation of impurities on the inner wall of the filter tank, which may reduce the filtering effect of the filter tank and affect the filtering efficiency of the entire exhaust gas filtering mechanism. It improves the stability and filtering efficiency of the exhaust gas filtering mechanism during long-term operation and saves the time and money costs for maintaining the exhaust gas filtering mechanism.

[0018] By setting up an impurity recovery component, when the knocking and vibrating component loses its effect and the filter element cannot be dredged by moving up and down, the height of the impurity recovery pipe is flush with the bottom of the filter element, and the impurity recovery pipe is connected to the bottom space of the filter element. Since the bottom of the filter element is inverted conical, the impurity recovery pipe can start to adsorb the tiny impurities that fall off the filter element due to shaking, adsorb the impurities that fall off due to the knocking of the knocking and vibrating component on the transmission rod and the inner wall of the filter tank, and the adsorbed impurities will be collected by the impurity adsorber inside the impurity recovery tank. When the impurity adsorber becomes blocked and loses its adsorption effect, the impurity adsorber can be replaced by opening the sliding door on one side of the impurity recovery tank to continue collecting the impurities inside the waste gas filtering mechanism. The clean gas filtered by the impurity recovery component will be re-input into the waste gas filtering mechanism through the output pipe. When the filter element resumes partial filtering effect and stops moving up and down, the impurity recovery component stops working, solving the problem of difficult treatment of impurities inside the waste gas filtering mechanism and reducing the maintenance cost of the equipment.

[0019] The structure of the present invention is simple, which can significantly improve the filtering effect of the filter and help the equipment maintain a stable filtering efficiency during long-term operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] An embodiment provided by the present invention is as Figures 1 to 7As shown in the figure, it includes an essential oil eutectic reactor assembly 10, an exhaust gas cooling assembly 20, an exhaust gas filtering mechanism 30, and an impurity recovery assembly 80. An exhaust gas outlet 11 is installed on the upper side wall of the essential oil eutectic reactor assembly 10.

One end of the air inlet end 21 is fixedly connected to the exhaust gas outlet 11, and one end of the cooling tank 22 is connected to the other end of the air inlet end 21. The cooling coil 23 is wound around the side wall of the cooling tank 22. The exhaust gas filtering mechanism 30 includes an exhaust gas pipe 32, a filtering tank 31, an air outlet 33, a driving fan assembly 40, a filtering assembly 70, a knocking and vibrating assembly 50, and a spring assembly 60.

One end of the air outlet 33 is fixedly connected to the top of the filtering tank 31, and the other end of the air outlet 33 is fixedly connected to one end of the cooling coil 23 adjacent to the essential oil eutectic reactor assembly 10. The driving fan assembly 40, the filtering assembly 70, the knocking and vibrating assembly 50, and the spring assembly 60 are all installed inside the filtering tank 31. The driving fan assembly 40 includes a driving fan 41 and a transmission rod 42.

The bottom of the filtering assembly 70 is sleeved on the top of the transmission rod 42. The knocking and vibrating assembly 50 is connected to the bottom of the filtering assembly 70. The bottom of the spring assembly 60 is connected to the top of the filtering assembly 70. The filtering assembly 70 is slidably installed inside the filtering tank 31. The impurity recovery assembly 80 is installed on the side wall of the filtering tank 31.

[0032] The filtering assembly 70 is composed of activated carbon and can adsorb and remove volatile organic compounds and tiny essential oil crystals in the exhaust gas. The exhaust gas cooling assembly 20 can cool the high-temperature exhaust gas generated during the essential oil eutectic reaction to a certain extent. The driving fan assembly 40 pushes the filtering assembly 70 to shake up and down by rotating, making the impurities in the filtering assembly 70 more evenly distributed and improving the filtering efficiency of the filtering assembly 70. The knocking and vibrating assembly 50 knocks on the filtering tank 31 to make the accumulated impurities on the filtering tank 31 fall off, avoiding the influence of impurity accumulation on the filtering efficiency of the filtering tank 31. The spring assembly 60 can fix the filtering assembly 70 and control the shaking amplitude and direction of the filtering assembly 70. The impurity recovery assembly 80 can adsorb the impurities shaken off by the knocking and vibrating assembly 50, improving the stability of the long-term operation of the entire exhaust gas filtering mechanism 30.

[0033] As Figure 1 and Figure 4As shown, the impurity recovery assembly 80 includes an impurity recovery pipe 81, an impurity recovery tank 82, and an output pipe 83. The lower end of the impurity recovery pipe 81 is fixedly connected to the side wall of the filtration tank 31, and the height of the lower end of the impurity recovery pipe 81 is equal to the height of the middle part of the filtration assembly 70.

[0034] As Figures 1 to 3 shown, the essential oil eutectic reactor assembly 10 includes a reactor body 12, a transmission device 13, a stirrer 14, and a feed inlet 15. The reactor body 12 is installed on the ground. The transmission device 13 is installed on the top of the reactor body 12.

The top of the stirrer 14 is connected to the transmission device 13. The feed inlet 15 is installed on the top of the reactor body 12, and the waste gas discharge port 11 is installed on the side wall of the reactor body 12.

[0035] As Figures 3 to 5 shown, the filtration assembly 70 includes a filter element 74, a square magnet element 75, and an annular magnet 76. The filter element 74 is slidably installed inside the filtration tank 31. The upper half of the square magnet element 75 is installed at the bottom of the filter element 74. The top of the annular magnet 76 is fixedly abutted against the bottom of the square magnet element 75, and the side wall of the annular magnet 76 is fixedly connected to the inner side wall of the filtration tank 31. The square magnet element 75 and the annular magnet 76 have opposite magnetic polarities.

[0036] As Figures 1 to 4 shown, a cavity 821 is formed inside the impurity recovery tank 82, an impurity adsorbent 85 is installed inside the cavity 821, and a sliding door 84 is installed on the side wall of the impurity recovery tank 82.

[0037] As Figure 5 and Figure 7 shown, a through groove 71 is formed in the middle of the filtration assembly 70. The through groove 71 penetrates through the lower side wall of the filtration assembly 70. A clamping groove 72 is formed on the upper side wall of the through groove 71. A spiral surface 73 is formed on the bottom side wall of the clamping groove 72. A clamping position groove 77 is formed on the bottom side wall of the through groove 71.

[0038] As Figures 3 to 7 shown, a limit block 421 is installed on the upper side wall of the upper end of the transmission rod 42. The limit block 421 is clamped in the clamping position groove 77. A fixing block 43 is fixedly installed at the top of the transmission rod 42. The fixing block 43 is clamped in the clamping groove 72, and a pushing rod 431 is formed at the bottom of the fixing block 43. The pushing rod 431 is located directly above the spiral surface 73. The top of the transmission rod 42 is inserted into the through groove 71.

[0039] AsFigure 3 As shown, the knocking and vibrating assembly 50 includes four rope pulling members 51 and four iron ball members 52. The tops of the four rope pulling members 51 are all connected to the bottom of the filtering assembly 70, and the four iron ball members 52 are fixedly connected to the bottoms of the four rope pulling members 51 respectively.

[0040] As Figures 1 to 3 shown, the spring assembly 60 includes four spring members 61 and a fixing plate 62. The bottoms of the four spring members 61 are all connected to the top of the filtering assembly 70, the bottom of the fixing plate 62 is connected to the tops of the four spring members 61, and the side wall of the fixing plate 62 is fixedly connected to the inner wall of the filtering tank 31.

[0041] As Figures 3 to 7 shown, activated carbon is stored inside the filtering assembly 70. The driving fan 41 includes a fixed shaft 413, a bearing 412 and three fan blades 411. The bottom of the fixed shaft 413 is fixedly connected to the bottom of the filtering tank 31. The bearing 412 is rotatably sleeved on the top of the fixed shaft 413. The top of the bearing 412 is fixedly connected to the bottom of the transmission rod 42. The three fan blades 411 are all connected to the side wall of the bearing 412 at a certain inclination angle and at the same interval.

[0042] During installation: The kettle body 12 is installed on the ground, the transmission device 13 is installed on the top of the kettle body 12, the stirrer 14 is installed inside the kettle body 12, the feed inlet 15 is installed on the top of the kettle body 12, the exhaust gas outlet 11 is installed on the side wall of the kettle body 12, the filtering assembly 70 is slidably installed inside the filtering tank 31, the impurity recovery assembly 80 is installed on the side wall of the filtering tank 31, and the upper half of the square magnet member 75 is installed at the bottom of the filtering member 74.

[0043] During use: 1. After the material enters the kettle body 12 through the feed inlet 15, close the feed inlet 15 to prevent material leakage or external impurities from entering during the eutectic reaction process. Start the transmission device 13, and the stirrer 14 starts to work, and the essential oil eutectic reaction begins. The exhaust gas generated during the essential oil eutectic reaction enters the cooling tank 22 through the exhaust gas outlet 11 and the intake end 21. The cooled gas enters the interior of the exhaust gas filtering mechanism 30 through the exhaust pipe 32. The impurities and harmful gas components in the exhaust gas will be filtered by the filtering assembly 70 containing activated carbon. The purified air enters the cooling coil 23 through the air outlet 33. Since the temperature of the exhaust gas entering the cooling coil 23 is relatively low, the cooling coil 23 can provide a certain degree of cooling for the cooling tank 22, so that the cooling tank 22 can maintain a relatively low temperature environment to continuously cool the high-temperature exhaust gas generated during the essential oil eutectic reaction.

[0044] 2. After long-term use, the filter element 74 becomes blocked. The impact pressure of the exhaust gas on the bottom of the filter element 74 increases. The exhaust gas pushes the filter element 74 to move upward. The square magnet piece 75 at the bottom of the filter element 74 separates from the annular magnet 76 fixed to the inner side wall of the filter tank 31. And the filter element 74 is forced to compress the spring assembly 60 upward, causing the clamping groove 77 to move upward synchronously. The limiting block 421 disengages from the clamping groove 77, and the transmission rod 42 is released from the restriction. The driving fan 41 rotates counterclockwise under the blowing of the exhaust gas at the bottom. The driving fan 41 drives the bearing 412 to rotate. The transmission rod 42 rotates following the bearing 412. And when the transmission rod 42 rotates, it drives the pushing rod 431 to rotate. The pushing rod 431 moves from the lowest point of the spiral surface 73 to the highest point of the spiral surface 73, and so on. When the pushing rod 431 pushes the spiral surface 73 to move, the spiral surface 73 causes the filter element 74 to shake up and down. During the up-and-down shaking of the filter element 74, the solid impurities attached to the bottom of the filter element 74 will fall off during the shaking, making the impurities adsorbed by the activated carbon more evenly distributed. The activated carbon inside the filter element 74 will also be redistributed evenly, causing the filter element 74 to be unclogged again and restoring part of the filtering effect. When the filtering effect of the filter element 74 is partially restored, under the action of its own gravity and the weight of the iron ball piece 52, the filter element 74 will move downward. When the filter element 74 moves downward to a certain position, the square magnet piece 75 and the annular magnet 76 will adsorb together under the action of the magnetic field until the limiting block 421 is restricted by the clamping groove 77 again, and the driving fan assembly 40 stops working.

[0045] 3. When the pushing rod 431 pushes the spiral surface 73 to move, the spiral surface 73 causes the filter element 74 to shake up and down. The filter element 74 drives the bottom knocking and vibrating assembly 50 to shake. The iron ball piece 52 continuously knocks on the transmission rod 42 and the inside of the filter tank 31 during the shaking, causing the impurities adsorbed on the transmission rod 42 and the inner wall of the filter tank 31 to fall off due to the vibration generated by the knocking. This avoids the accumulation of impurities on the transmission rod 42 resulting in the loss of function of the transmission rod 42, and also avoids the accumulation of impurities on the inner wall of the filter tank 31 causing a decrease in the filtering effect of the filter tank 31 and affecting the filtering efficiency of the entire exhaust gas filtering mechanism 30, improving the stability and filtering efficiency of the exhaust gas filtering mechanism 30 during long-term operation, and saving the time and cost of maintaining the exhaust gas filtering mechanism 30.

[0046] 4. When the knocking and vibration assembly 50 loses its effect and the filter element 74 cannot be dredged by moving up and down, the height of the impurity recovery pipe 81 is flush with the bottom of the filter element 74, and the impurity recovery pipe 81 is communicated with the bottom space of the filter element 74. Since the bottom of the filter element 74 is inverted conical, the impurity recovery pipe 81 can start to adsorb the tiny impurities dropped from the filter element 74 due to shaking, adsorb the impurities dropped due to the knocking of the knocking and vibration assembly 50 on the transmission rod 42 and the inner wall of the filter tank 31, and the adsorbed impurities will be collected by the impurity adsorber 85 inside the impurity recovery tank 82. When the impurity adsorber 85 is blocked and loses its adsorption effect, the impurity adsorber 85 can be replaced by opening the sliding door 84 on one side of the impurity recovery tank 82 to continue collecting the impurities inside the waste gas filtering mechanism 30. The clean gas filtered by the impurity recovery assembly 80 will be re-introduced into the waste gas filtering mechanism 30 through the output pipe 83. When the filter element 74 resumes partial filtering effect and stops moving up and down, the impurity recovery assembly 80 stops working, solving the problem of difficult treatment of impurities inside the waste gas filtering mechanism 30 and reducing the maintenance cost of the equipment. [[ID=Z]]

[0047] By setting the cooling coil 23, after the material enters the kettle body 12 through the feed inlet 15, the feed inlet 15 is closed to prevent material leakage or entry of external impurities during the eutectic reaction process. The transmission device 13 is started, and the stirrer 14 starts to work, and the essential oil eutectic reaction begins. The waste gas generated during the essential oil eutectic reaction is discharged from the waste gas outlet 11 and enters the cooling tank 22 through the intake end 21 of the waste gas cooling assembly 20. The cooled gas enters the inside of the waste gas filtering mechanism 30 through the waste gas pipe 32. The impurities and harmful gas components in the waste gas will be filtered by the filter assembly 70 containing activated carbon. The purified air enters the cooling coil 23 through the air outlet 33. Since the temperature of the waste gas entering the cooling coil 23 is relatively low, the cooling coil 23 can provide a certain degree of cooling for the cooling tank 22, enabling the cooling tank 22 to maintain a relatively low temperature environment to continuously cool the high-temperature waste gas generated during the essential oil eutectic reaction.

[0048] By setting the pushing rod 431 and the spiral surface 73, after long-term use, when the filter element 74 becomes blocked and the impact pressure of the exhaust gas on the bottom of the filter element 74 increases, the exhaust gas pushes the filter element 74 to move upward. The square magnet 75 at the bottom of the filter element 74 separates from the annular magnet 76 fixed on the inner side wall of the filter tank 31, and the filter element 74 compresses the spring assembly 60 upward under the force, causing the clamping groove 77 to move upward synchronously, and the limiting block 421 disengages from the clamping groove 77, releasing the restriction on the transmission rod 42. The driving fan 41 rotates counterclockwise under the blowing of the bottom exhaust gas. The driving fan 41 drives the bearing 412 to rotate, and the transmission rod 42 rotates following the bearing 412. When the transmission rod 42 rotates, it drives the pushing rod 431 to rotate. The pushing rod 431 moves from the lowest point of the spiral surface 73 to the highest point of the spiral surface 73, and this process repeats. When the pushing rod 431 pushes the spiral surface 73 to move, the spiral surface 73 causes the filter element 74 to shake up and down. During the up and down shaking of the filter element 74, the solid impurities attached to the bottom of the filter element 74 will fall off during the shaking, making the impurities adsorbed by the activated carbon more evenly distributed, and the activated carbon inside the filter element 74 will also be redistributed evenly, so that the filter element 74 is unclogged again and part of the filtering effect is restored. When the filtering effect of the filter element 74 is partially restored, the filter element 74 will move downward under the action of its own gravity and the weight of the iron ball 52. When the filter element 74 moves downward to a certain position, under the magnetic attraction of the square magnet 75 and the annular magnet 76, the square magnet 75 and the annular magnet 76 will adsorb together until the limiting block 421 is restricted by the clamping groove 77 again, and the driving fan assembly 40 stops working.

[0049] By setting the iron ball 52, when the pushing rod 431 pushes the spiral surface 73 to move, the spiral surface 73 causes the filter element 74 to shake up and down. The filter element 74 drives the knocking and vibrating assembly 50 at the bottom to shake. The iron ball 52 continuously knocks on the transmission rod 42 and the inside of the filter tank 31 during the shaking, causing the impurities adsorbed on the transmission rod 42 and the inner wall of the filter tank 31 to fall off due to the vibration generated by the knocking. This avoids the accumulation of impurities on the transmission rod 42, which may cause the transmission rod 42 to lose its function, and also avoids the accumulation of impurities on the inner wall of the filter tank 31, which may reduce the filtering effect of the filter tank 31 and affect the filtering efficiency of the entire exhaust gas filtering mechanism 30, improving the stability and filtering efficiency of the exhaust gas filtering mechanism 30 during long-term operation, and saving the time and money costs for maintaining the exhaust gas filtering mechanism 30.

[0050] By setting up the impurity adsorbent 85, when the knocking and vibrating component 50 loses its effect and the filter element 74 cannot be dredged by moving up and down, the height of the impurity recovery pipe 81 is flush with the bottom of the filter element 74, and the impurity recovery pipe 81 is communicated with the bottom space of the filter element 74. Since the bottom of the filter element 74 is inverted conical, the impurity recovery pipe 81 can start to adsorb the tiny impurities that fall off the filter element 74 due to shaking, adsorb the impurities that fall off due to the knocking of the knocking and vibrating component 50 on the transmission rod 42 and the inner wall of the filter tank 31, and the adsorbed impurities will be collected by the impurity adsorbent 85 inside the impurity recovery tank 82. When the impurity adsorbent 85 is blocked and loses its adsorption effect, the impurity adsorbent 85 can be replaced by opening the sliding door 84 on one side of the impurity recovery tank 82 to continue collecting the impurities inside the waste gas filtering mechanism 30. The clean gas filtered by the impurity recovery component 80 will be re-input into the waste gas filtering mechanism 30 through the output pipe 83. When the filter element 74 recovers part of its filtering effect and stops moving up and down, the impurity recovery component 80 stops working, solving the problem of difficult treatment of impurities inside the waste gas filtering mechanism 30 and reducing the maintenance cost of the equipment.

[0051] The structure of the present invention is simple, which can significantly improve the filtering effect of the filter, helps the equipment to maintain a stable filtering efficiency during long-term operation, solves the problem of frequent replacement of the filter screen during the production process, improves the production efficiency, and reduces the labor and financial costs of equipment maintenance.

[0052] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0053] The above-described embodiments only represent several embodiments of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the appended claims.
