Description

Technical Field

[0001] The invention relates to the technical field related to electrostatic precipitators, and in particular to an intermittent high-frequency power supply control mechanism for an electrostatic precipitator. Background Art

[0002] Electrostatic precipitator, also known as electrostatic precipitator, is an environmental protection equipment that efficiently uses the principle of electrostatics to remove particulate dust from flue gas. This equipment is widely used in thermal power plants, steel mill sintering machines, boilers and other industrial emission sources, aiming to significantly reduce the amount of dust discharged into the atmosphere, thereby significantly improving environmental quality and raising air quality standards.

[0003] The working mechanism of the electrostatic precipitator is based on the principle of electrostatic adsorption. Specifically, when the flue gas containing smoke flows through the flue in front of the main structure of the electrostatic precipitator, the smoke particles will be given a positive charge by the corona coil. Then, these charged flue gases enter the electrostatic precipitator channel equipped with multiple layers of dust collecting plates. Since the dust collecting plates are usually negatively charged or grounded to form an electric field, the positively charged smoke particles are strongly attracted by electrostatic attraction and are firmly adsorbed on the dust collecting plates. In order to remove the accumulated smoke, the system will periodically apply mechanical knocking or vibration to the dust collecting plates, so that the smoke particles attached to the plates fall off under the combined action of their own weight and vibration force, and fall into the ash hopper below the electrostatic precipitator, ultimately achieving flue gas purification.

[0004] However, in actual operation, a significant problem is that when the dust collecting plate is still connected to the high-frequency power supply during the tapping process, the smoke and dust particles are difficult to fall off due to the continuous action of the electrostatic force, which often requires a greater tapping force to ensure the effective removal of the smoke and dust. This may not only cause the dust collecting plate to be damaged due to excessive force, but also increase energy consumption due to the continuous high-frequency power supply, resulting in unnecessary energy waste. In the long run, this will increase the operating costs of the enterprise and reduce the efficiency of equipment use. Summary of the invention

[0005] The present invention proposes an intermittent high-frequency power supply control mechanism for an electrostatic precipitator, which has the advantage of intermittent controlled power supply and is used to solve the problem in the above background technology that the dust collecting plate is continuously connected to the high-frequency power supply, resulting in dust being difficult to separate and increased useless energy consumption.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an intermittent high-frequency power supply control mechanism for an electrostatic precipitator, comprising: a dust removal shell, a fan inputs smoke from an air inlet horn into the inner cavity of the dust removal shell, the purified airflow is discharged from the air outlet horn, and the collected dust particles fall into the ash hopper, an adjustment part and a reset part located on one side of the adjustment part are provided on the inner side of the dust removal shell; a motor is fixed on the top of the dust removal shell, a co-rotating gear set is arranged on the output shaft of the motor, and a support cylinder is fixed to the output end of the co-rotating gear set, and a collector seat is coaxially fastened to the bottom of the support cylinder; a dust collecting plate is fixed on the outside of the support cylinder, and the dust collecting plate is fixed on the outside of the support cylinder. A locking hole is provided on the top of the outer side of the electric board; a distribution cabinet is used to apply high-frequency power to the dust collecting electric board; a distribution fork is movably arranged on the outer side of the dust collecting electric board, and an electric shock ball is fixedly installed on the top of the distribution fork, and a power rack is fixedly installed on the top of the inner side of the dust collecting shell; an adjustment push rod is movably arranged in the distribution fork, and an adjustment spring is connected between the adjustment push rod and the distribution fork; a magnetic block is fixed on the inner side of the dust collecting shell, and is used to attract the adjustment push rod to make it disengage from the locking hole; the motor drives the support cylinder to rotate, and the dust collecting electric board close to the flue gas path is connected to adsorb dust particles; the dust collecting electric board far away from the flue gas path is disconnected to reduce useless losses.

[0007] Furthermore, there are multiple dust collecting plates, and the multiple dust collecting plates are distributed at equal angles on the outer side of the support tube.

[0008] Furthermore, the reset portion is an inclined surface with a smooth surface.

[0009] Furthermore, a guide portion located between the adjustment portion and the reset portion is provided on the inner side of the dust removal housing.

[0010] Furthermore, a dust discharge groove is provided at the bottom of the dust removal shell and is located on one side of the guide portion.

[0011] Furthermore, a switch start arm located on one side of the guide part is movably installed on the inner side of the dust removal shell, a reset top spring is arranged between the switch start arm and the dust removal shell, and a start-stop switch located below the switch start arm is fixed on the dust removal shell.

[0012] Furthermore, a boost push spring is connected between the inner top of the dust collecting electric plate and the distribution fork.

[0013] Furthermore, a cleaning tooth row is fastened to the outer side of the dust collecting plate, and the cleaning tooth row is located directly below the locking hole.

[0014] Furthermore, a reset groove is provided on the side of the dust collecting plate and is located on one side of the cleaning tooth row. A reset slide groove is provided between the top of the reset groove and the locking hole. A shift slider is movably installed in the distribution fork, and the adjustment push rod is installed on the shift slider. A limit stop rod is fixed on the inner side of the dust removal shell.

[0015] Furthermore, a middle partition is fastened to the top of the outer side of the dust collecting plate, and the middle partition is located between the reset groove and the top of the cleaning tooth row.

[0016] The present invention has the following beneficial effects:

[0017] The present invention provides an intermittent high-frequency power supply control mechanism designed for an electrostatic precipitator. The unique feature of the mechanism is that an innovative power distribution fork assembly is flexibly installed on the outside of the dust collecting plate. When the dust collecting plate rotates to the flue gas circulation area, the power distribution fork will be electrically connected to the power distribution cabinet to ensure that the dust collecting plate is smoothly connected to the high-frequency power supply, thereby starting the dust removal operation. At this time, the dust collecting plate is charged, and the electrostatic field generated by it is used to effectively absorb particulate smoke in the flue gas.

[0018] As the motor drives the dust collecting plate to continue to rotate, when the dust collecting plate gradually moves away from the smoke circulation area and enters the dust cleaning stage, the distribution fork will intelligently slide down along the preset trajectory and cleverly disconnect from the power distribution cabinet, thereby ensuring that the dust collecting plate is no longer connected to the high-frequency power supply during the dust cleaning process. This design cleverly avoids the problem of dust being difficult to fall off due to continuous power supply during the dust cleaning process, and also reduces energy consumption caused by unnecessary power supply.

[0019] During the continuous rotation of the dust collecting plate, the power distribution fork can accurately control the intermittent on and off of the dust collecting plate. This not only ensures that the dust collecting plate can be connected to the power supply in time for dust removal when needed, but also can be quickly disconnected when cleaning, thereby greatly reducing the loss of useless power and improving the energy efficiency of the entire electrostatic precipitator.

[0020] Finally, through the application of this intermittent high-frequency power supply control mechanism, the electrostatic precipitator achieved a more efficient intermittent control power supply effect, which not only optimized the dust removal performance, but also significantly reduced the operating cost. In addition, the mechanism also has the advantages of simple structure, convenient operation, and low maintenance cost, providing new ideas and technical support for the intelligent and energy-saving transformation of the electrostatic precipitator.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figure 1It can be seen that the dust removal housing 1 is fixed at a desired position by a steel frame at the bottom. The fan inputs the dust-containing airflow to be processed from the air inlet horn 100 into the inner cavity of the dust removal housing 1. After the dust-containing airflow is purified and dusted in the dust removal housing 1, the purified airflow is discharged from the air outlet horn 101. The dust collecting hopper 5 is used to collect the adsorbed dust particles. When cleaning is required, the discharge valve fixed at the bottom of the dust collecting hopper 5 is opened to realize the output of the dust particles.

[0036] The dust collecting plate 7 of the present invention adopts a rotating intermittent power supply type dust collecting, and the motor 3 is used as the main power driving part. A co-rotating gear set 4 is arranged on its output shaft. The co-rotating gear set 4 includes two gears of the same size, and the two gears are meshed and driven. One of the gears is coaxially fastened with the output end of the motor 3. Specifically, Figure 6 It can be clearly seen that the two gears are coaxially fastened with a support tube 6, which is cylindrical in shape. The dust collecting plate 7 is fixed on the outside of the support tube 6, and a plurality of dust collecting plates 7 with equal angles are arranged on the outside of a support tube 6. The attached figure of the present invention takes eight as an example, and the actual number can be changed according to the use requirements. Figure 2 It can be seen that when the dust collecting plates 7 on the two support tubes 6 are staggered, a path for the flue gas to pass through is reserved. When the flue gas passes through the corona coil 10 and is charged, the charged dust can be adsorbed and collected by the dust collecting plates 7 when passing through the dust collecting plates 7, thereby achieving the dust removal function.

[0037] Due to the design of the above special structure, the airflow only flows through the reserved path between the dust collecting plates 7. In the actual application process, in order to reduce energy consumption, the dust collecting plates 7 passing through the flue gas are in a working state, and the dust collecting plates 7 not passing through the flue gas are in a power-off state, which can greatly reduce the useless loss of electric energy. Figure 1 It can be clearly seen that there is a power distribution cabinet 2 connected by bolts on the top of the dust collecting housing 1. The power distribution cabinet 2 is mainly used to apply electric energy to the dust collecting plate 7 to ensure that the dust collecting plate 7 can adsorb dust particles in the airflow. Figure 5-Figure 7 It can be clearly seen that a distribution fork 8 is movably installed on the outside of each dust collecting plate 7, and the distribution fork 8 can only reciprocate up and down along the dust collecting plate 7. Since the distribution fork 8 and the dust collecting plate 7 are in relative contact, the dust collecting plate 7 can be connected to the distribution cabinet 2 by using the distribution fork 8. Furthermore, an electric shock ball 9 is fixedly installed on the top of the distribution fork 8, corresponding to which, refer to Figure 4It can be seen that a mounting bracket 11 is fixedly installed on the top of the inner side of the dust removal housing 1. The mounting bracket 11 is in the shape of a combination of two circular rings, and the circular rings are the movement path of the electric shock ball 9. When in use, the mounting bracket 11 is connected to the distribution cabinet 2 via cables. When the electric shock ball 9 on the distribution fork 8 contacts the mounting bracket 11, the dust collecting plate 7 can be connected to the support tube 6 through the distribution fork 8, the electric shock ball 9 and the mounting bracket 11. Figure 7 It can be clearly seen that the bottom of the support tube 6 is coaxially fastened with a collector seat 600, and the collector seat 600 and all the dust collecting plates 7 on the support tube 6 are in contact and connected, and the collector seat 600 and the support tube 6 are connected by cables. Therefore, when the electric ball 9 and the electric frame 11 are connected, the dust collecting plates 7 will be connected to the high-frequency power supply to achieve the adsorption of dust particles.

[0038] The distribution fork 8 is provided with an adjustment push rod 15, which is combined with Figure 8-Figure 10 It can be seen that an adjustment spring 150 is connected between the adjustment push rod 15 and the distribution fork 8. Due to the elastic force of the adjustment spring 150, the adjustment push rod 15 always tends to move toward the dust collecting plate 7. Correspondingly, a locking hole 19 is provided on the top of the outer side of the dust collecting plate 7. When the distribution fork 8 moves to the top of the dust collecting plate 7, the adjustment push rod 15 is pushed into the locking hole 19 by the elastic force of the adjustment spring 150, so that the distribution fork 8 is locked on the top of the dust collecting plate 7. At the same time, the electric shock ball 9 on the distribution fork 8 will also be pushed against the electric mounting frame 11, so that the electric shock ball 9 and the electric mounting frame 11 are connected. On this basis, combined with Figure 5 and Figure 6 It can be seen that an adjustment portion 102 is provided inside the dust collecting housing 1, and the height of the adjustment portion 102 is relatively low. When the support tube 6 drives the electric shock ball 9 to rotate above the adjustment portion 102, the electric shock ball 9 is relatively far away from the above-mentioned flue gas flow path. At the same time, the dust collecting plate 7 does not need to be continuously energized because there is no airflow passing through it. Figure 5 As shown, a magnetic block 14 located on one side of the adjustment part 102 is fixedly installed on the inner side of the dust removal shell 1. When the electric shock ball 9 moves to the adjustment part 102, the distribution fork 8 also drives the adjustment push rod 15 to be opposite to the magnetic block 14. The adjustment push rod 15 is magnetically attracted by the magnetic block 14 and will relatively compress the adjustment spring 150 and disengage from the locking hole 19, thereby releasing the movement restriction of the distribution fork 8 by the adjustment push rod 15. Afterwards, under the action of gravity of the distribution fork 8, it will move downward along the dust collecting plate 7 and make the electric shock ball 9 relatively away from the power rack 11. At this time, the dust collecting plate 7 will no longer be connected.

[0039] The inner side of the dust removal housing 1 is provided with a reset portion 104 located on one side of the adjustment portion 102. Figure 6It can be seen that the reset portion 104 is a smooth inclined surface. When the distribution fork 8 moves upward along the reset portion 104, the height of the distribution fork 8 will gradually be higher than the adjustment portion 102. Finally, as the distribution fork 8 continues to move upward, the adjustment push rod 15 will be inserted into the locking hole 19 again. At this time, the dust collecting plate 7 will also move closer to the flue gas flow path to ensure that the dust collecting plate 7 close to the flue gas can absorb the dust in the flue gas.

[0040] When the first embodiment of the present invention is used, the dust collecting plate 7 is driven to rotate by the motor 3, and the distribution fork 8 that rotates with the dust collecting plate 7 passes through the adjustment part 102 and the reset part 104 in sequence. When the distribution fork 8 passes through the reset part 104, the distribution fork 8 moving along the reset part 104 will move upward, so that the adjustment push rod 15 is relatively close to the locking hole 19 until the adjustment push rod 15 is inserted into the locking hole 19. At this time, the adjustment push rod 15 limits the distribution fork 8, so that the distribution fork 8 is always at the top of the outer side of the dust collecting plate 7. At the same time, the electric ball 9 on the distribution fork 8 will abut against the power rack 11, so that the two are connected, and finally the dust collecting plate 7 connected thereto is connected to the high-frequency power supply. From Figure 2 It can be seen that as the dust collecting plate 7 connected to the high frequency power source approaches the flue gas transmission path, it will adsorb the dust particles in the flue gas. The two support cylinders 6 are driven by the co-rotating gear set 4 to make the support cylinders 6 rotate synchronously. At the same time, the dust collecting plates 7 on the two support cylinders 6 will not touch each other, avoiding the problem that the dust collecting plates 7 on the two support cylinders 6 cannot pass normally due to contact.

[0041] As the support tube 6 rotates, the dust collecting plate 7 after adsorbing the smoke particles will also rotate toward the adjustment part 102. When the dust collecting plate 7 drives the distribution fork 8 to move to the adjustment part 102, the height of the adjustment part 102 is relatively reduced, and the magnetic block 14 magnetically attracts the adjustment push rod 15, so that the adjustment push rod 15 is separated from the locking hole 19 and the movement restriction of the distribution fork 8 is released. Under this condition, the distribution fork 8 moves downward due to its own gravity, so that the electric shock ball 9 is separated from the power rack 11, and the dust collecting plate 7 will also be in a disconnected state.

[0042] Since the motor 3 drives the support tube 6 to rotate continuously, it can be seen that the dust collecting plate 7 close to the flue gas path will be connected to adsorb dust particles; the dust collecting plate 7 far away from the flue gas path will be disconnected to reduce useless losses. During the implementation process, the dust collecting plate 7 can connect / disconnect the high-frequency power supply in a timely manner according to the needs of use, ensuring that the dust collecting plate 7 can be started and stopped intermittently, solving the defect that the dust collecting plate 7 is always connected to the high-frequency power supply under normal circumstances, greatly reducing the useless loss of the equipment, and ultimately shortening the application cost of the enterprise.

[0043] The second embodiment is a further improvement on the basis of the first embodiment. In order to realize that the dust particles adsorbed on the outer side of the dust collecting plate 7 can be completely cleaned into the dust collecting hopper 5, please refer to Figure 5-Figure 6 It can be seen that the inner side of the dust removal housing 1 is provided with a guide portion 103 located between the adjustment portion 102 and the reset portion 104, and the surface of the guide portion 103 is relatively horizontal. Figure 6 It can be clearly seen that there is a height difference between the left end of the guide portion 103 and the adjustment portion 102, and the right end is located at the lowest part of the slope of the reset portion 104. In addition, when the distribution fork 8 contacts the guide portion 103, the distribution fork 8 also moves to the lower side of the dust collecting plate 7 at the same time. In summary, when the distribution fork 8 moves to the adjustment portion 102, the magnetic attraction of the magnetic block 14 to the adjustment push rod 15 will force the adjustment push rod 15 to release the movement restriction on the distribution fork 8, and the distribution fork 8 is attached to the surface of the adjustment portion 102 due to gravity. At this time, the dust collecting plate 7 is in a power-off state. As the motor 3 drives the support tube 6 to rotate, the distribution fork 8 will also detach from the adjustment portion 102 and be above the guide portion 103. Since the adjustment portion 102 no longer provides support for the distribution fork 8, the distribution fork 8 will continue to move downward under the action of gravity. Combined with Figure 7 It can be seen that the downward distribution fork 8 will scrape the dust adsorption surfaces on both sides of the dust collecting plate 7, so that the adsorbed dust is scraped out of the dust collecting plate 7. Considering that the dust collecting plate 7 is in a power-off state at this time, the scraped dust particles will not be adsorbed again by the dust collecting plate 7, further increasing the efficiency of dust scraping. When the distribution fork 8 descends to the guide part 103, the comprehensive scraping work on the outside of the dust collecting plate 7 will also be completed. Finally, with the rotation of the support tube 6, the distribution fork 8 moves upward along the reset part 104, and after the dust collecting plate 7 is connected to the high-frequency power supply, the dust particles in the flue gas are adsorbed again. In this way, the dust adsorption surface of the dust collecting plate 7 is fully cleaned after the power is turned off.

[0044] For the collection of dust scraped off the outside of the dust collecting plate 7, combined with Figure 6 It can be seen that a dust discharge groove 500 is provided at the bottom of the dust removal housing 1 on one side of the guide portion 103, and the opening shape of the dust discharge groove 500 is fan-shaped, thereby ensuring that after the dust is scraped out from the dust collecting plate 7, it will fall from the ash discharge groove 500 into the ash collecting hopper 5 for collection.

[0045] On this basis, in order to allow the distribution fork 8 to have enough time to clean the dust particles adsorbed on the outside of the dust collecting plate 7, combined with Figure 5 and Figure 6It can be seen that a switch start arm 12 located on one side of the guide portion 103 is movably installed inside the dust removal housing 1. Since the switch start arm 12 is movably arranged on the guide rod arranged vertically in the dust removal housing 1, the switch start arm 12 is limited by the guide rod and can only move up and down within a certain range. By using the reset top spring 120 arranged between the switch start arm 12 and the dust removal housing 1, the reset top spring 120 forces the switch start arm 12 to always be in the upper limit position under the push of elastic force. Finally, the upward switch start arm 12 will release the suppression of the start-stop switch 16 below. Specifically, the start-stop switch 16 is fixed on the dust removal housing 1 and is located below the switch start arm 12. When the switch start arm 12 is pushed downward by the distribution fork 8 to suppress the start-stop switch 16 to be turned on, the motor 3 connected to the start-stop switch 16 will start to rotate; similarly, when the switch start arm 12 releases the suppression of the start-stop switch 16, the motor 3 stops working. Specifically, in actual application, when the start-stop switch 16 is not pressed by the switch start arm 12, the motor 3 stops working. At this time, the distribution fork 8 located above the switch start arm 12 slides downward along the dust collecting plate 7 under its own gravity, and scrapes out the dust particles adsorbed on the outside of the dust collecting plate 7 during the sliding process. The dust particles will eventually fall into the ash collecting hopper 5 through the ash discharge groove 500 for collection. As the distribution fork 8 continues to move downward, it will eventually push the switch start arm 12 downward to press the reset top spring 120 and the start-stop switch 16. With the start-stop switch 16 being pressed, the motor 3 is started, and the dust collecting plate 7 is driven to rotate according to the support tube 6, forcing the dust collecting plate 7 to drive the distribution fork 8 to move toward the reset portion 104. When the distribution fork 8 is separated from the switch start arm 12, the distribution fork 8 will also release the pressure on the switch start arm 12, and the switch start arm 12 will be forced upward and release the pressure on the start-stop switch 16 under the elastic force of the reset top spring 120. At this time, the upward switch start arm 12 will be relatively higher than the distribution fork 8, thereby preventing the distribution fork 8 from rotating in the opposite direction and squeezing the switch start arm 12 again. In addition, as the distribution fork 8 on the dust collecting plate 7 is separated from the switch start arm 12, the next distribution fork 8 will move to the top of the switch start arm 12 following the rotation of the dust collecting plate 7, so as to wait for the next distribution fork 8 to fully clean the outside of the dust collecting plate 7 before squeezing the start-stop switch 16 again. This cycle ensures that the motor 3 is started intermittently, so that the distribution fork 8 can fully clean the outside of the dust collecting plate 7.

[0046] The third embodiment is a further improvement on the second embodiment. The third embodiment aims to enhance the cleaning strength of the distribution fork 8 on the dust collecting plate 7 and reduce energy consumption. Fig. 9 and Fig.10It can be clearly seen that a booster spring 22 is connected between the inner top of the dust collecting plate 7 and the distribution fork 8. Under the influence of the elastic force of the booster spring 22 and the gravity of the distribution fork 8, the distribution fork 8 is forced to always have a tendency to move downward. Therefore, when the distribution fork 8 moves downward along the dust collecting plate 7, it is not only affected by its own gravity, but also by the elastic force of the booster spring 22, which increases the scraping strength of the distribution fork 8 on the outside of the dust collecting plate 7, thereby preventing the distribution fork 8 from being affected by its own gravity after encountering a stubborn dust layer, resulting in a phenomenon in which the cleaning force is not strong enough.

[0047] Moreover, combined with Figure 6 It can be seen that the vertical surface between the adjustment part 102 and the guide part 103 is relatively rough. When the support tube 6 drives the distribution fork 8 away from the switch start arm 12, the next distribution fork 8 will move above the switch start arm 12. Combined with the above, the distribution fork 8 will move downward due to its own gravity and the elastic force of the booster spring 22. At the same time, there are still distribution forks 8 on the reset part 104 that have not completely moved up to the limit. Figure 6 It can be seen that when the booster spring 22 pushes the distribution fork 8 to move along the reset portion 104, it will force the support tube 6 to rotate clockwise, and the distribution fork 8 above the guide portion 103 will rotate in the opposite direction and stick to the vertical rough surface between the reset top spring 120 and the guide portion 103, so that the distribution fork 8 and the vertical rough surface are in contact, and finally the friction between the two is increased, thereby slowing down the speed of the distribution fork 8 approaching the switch start arm 12 downward. The reason is: combined with Figure 6 It can be seen that when the flue gas flows from the right to the left, the airflow will push the dust collecting plate 7 to force the support tube 6 to have a tendency to move counterclockwise. If the airflow intensity weakens at this time, it means that the fan has not sent the flue gas in, and the distribution fork 8 that slows down in downward movement will cause the starting time of the start-stop switch 16 to be slowed down, thereby reducing the frequent start and stop of the motor 3 and reducing energy consumption; similarly, if the fan sends the flue gas in, the airflow will push the dust collecting plate 7 to force it to rotate counterclockwise with increasing intensity, causing the distribution fork 8 to be relatively away from the vertical rough surface. Combined with the elastic force of the booster push spring 22 and the gravity of the distribution fork 8 itself, the distribution fork 8 is forced to quickly descend and suppress the switch starting arm 12, thereby shortening the starting cycle of the motor 3 and ensuring that the dust collecting plate 7 can switch more quickly. The cleaned dust collecting plate 7 will relatively enhance the adsorption intensity of dust particles, thereby increasing the purification effect of the flue gas.

[0048] Example 4 is a supplement to Example 3. Please refer to Figure 8-Figure 10 It can be seen that the outer side of the dust collecting plate 7 is provided with a cleaning tooth row 17 fastened by bolts, and the cleaning tooth row 17 is located directly below the locking hole 19. Fig.10It can be clearly seen that the tooth shape of the cleaning tooth row 17 is a right triangle. When the distribution fork 8 moves downward, the adjustment push rod 15 continuously passes over the right triangle slope of the cleaning tooth row 17, and will continuously impact the dust collecting plate 7, thereby utilizing the impact to enhance the cleaning intensity of the dust collecting plate 7, so that the dust collecting plate 7 is cleaned in a synchronous manner of knocking + scraping, thereby enhancing the cleaning efficiency.

[0049] Moreover, from Figure 8-Figure 10 It can be clearly seen that the side of the dust collecting plate 7 is provided with a reset groove 18 located on one side of the cleaning tooth row 17, and the reset groove 18 is an inclined surface, wherein the high part of the inclined surface is located above the reset groove 18, and the height of the inclined surface is relatively lower than the cleaning tooth row 17, and a reset chute 20 is provided between the top of the reset groove 18 and the locking hole 19, and the reset chute 20 is also an inclined surface, and the locking hole 19 is located at the lower part of the inclined surface. Fig.10 It can be seen that a transposition slider 23 is movably installed in the distribution fork 8, and the adjustment push rod 15 is installed on the transposition slider 23, so that the transposition slider 23 drives the adjustment push rod 15 to move left and right on the distribution fork 8.

[0050] Specifically, after the distribution fork 8 passes through the adjustment portion 102, the magnetic attraction of the magnetic block 14 forces the adjustment push rod 15 to disengage from the locking hole 19. At this time, the booster spring 22 pushes the distribution fork 8 downward under the elastic force, and causes the adjustment push rod 15 to move along the cleaning tooth row 17. Until the distribution fork 8 is attached to the adjustment portion 102, as the support cylinder 6 continues to rotate, the distribution fork 8 will also be separated from the adjustment portion 102 and located above the switch start arm 12. In this process, combined with Fig.10 It can be seen that in order to prevent the adjustment push rod 15 from being blocked and accidentally moving toward the reset groove 18 during the movement of the distribution fork 8 toward the top of the switch starting arm 12, an intermediate partition 21 fastened by bolts is provided at the top of the outer side of the dust collecting plate 7, and the intermediate partition 21 is located between the reset groove 18 and the top of the cleaning tooth row 17. The intermediate partition 21 blocks the adjustment push rod 15, thereby limiting the accidental movement of the adjustment push rod 15 during the movement of the distribution fork 8.

[0051] Afterwards, the distribution fork 8 located above the switch starting arm 12 will be pushed downward by the elastic force of the boost push spring 22. If no smoke is input into the dust removal housing 1 at this time, as mentioned above, the distribution fork 8 will stick to the vertical rough surface and move slowly. At the same time, the adjustment push rod 15 will move downward along the cleaning tooth row 17, further slowing down the downward speed of the distribution fork 8, and the adjustment push rod 15 is used to continuously cross the inclined surface of the cleaning tooth row 17, forcing the adjustment push rod 15 to continuously collide with the cleaning tooth row 17, thereby achieving vibration cleaning.

[0052] If the fan conveys the flue gas to the dust removal housing 1, combined with Figure 6It can be seen that the airflow will blow the support tube 6 to have a counterclockwise deflection tendency. Since there is a limit stopper 13 fixed on the upper side of the switch start arm 12 by bolts on the inner side of the dust removal housing 1, when the distribution fork 8 drives the extended adjustment push rod 15 to move and reach the limit stopper 13, the limit stopper 13 will block the extended adjustment push rod 15. As the distribution fork 8 drives the transposition slider 23 to rotate continuously counterclockwise, it will force the adjustment push rod 15 to have a tendency to move toward the reset groove 18. After the adjustment push rod 15 slides from the cleaning tooth row 17 to the reset groove 18, due to the high-up and low-down arrangement of the reset groove 18, the adjustment spring 150 is forced to push the adjustment push rod 15 out, and the adjustment push rod 15 has a tendency to move downward along the reset groove 18, thereby enhancing the downward strength of the distribution fork 8, ensuring that the downward strength of the distribution fork 8 is increased when smoke passes through.

[0053] When the descending distribution fork 8 contacts the switch start arm 12, the adjustment push rod 15 will also be pressed on the switch start arm 12, and the support tube 6 drives the distribution fork 8 to rotate counterclockwise, forcing the distribution fork 8 to move away from the switch start arm 12. In this process, since the adjustment push rod 15 presses the switch start arm 12 and follows the dust collecting plate 7 away from the switch start arm 12, the adjustment push rod 15 will eventually move to the reset groove 18.

[0054] When the distribution fork 8 moves to the reset portion 104, it is pushed by the boost push spring 22 so that the distribution fork 8 tends to move downward along the reset portion 104. The adjustment push rod 15 is also used to push the reset groove 18 to force the distribution fork 8 to have a tendency to move downward, thereby ensuring that when no smoke enters the dust removal housing 1, the adjustment spring 150 and the boost push spring 22 are used to force the distribution fork 8 to increase its strength against the vertical rough surface, thereby further limiting the speed at which the distribution fork 8 moves downward.

[0055] Finally, when the distribution fork 8 passes over the reset portion 104, the adjustment push rod 15 will also reach the top of the reset slot 20, and then, under the push of the adjustment spring 150, the adjustment push rod 15 is forced to slide along the reset slot 20 into the locking hole 19. In this way, the adjustment push rod 15 locks the distribution fork 8 on the top of the dust collecting plate 7 and ensures that the electric shock ball 9 and the electric frame 11 are connected.
