Description

Technical Field

[0001] The invention relates to the technical field of electrostatic precipitator top vibration electromagnetic drive, in particular to an electrostatic precipitator top vibration electromagnetic drive module. Background Art

[0002] Electrostatic precipitator is an important environmental protection equipment to improve environmental pollution and air quality. The working principle of electrostatic precipitator is that when the dust-containing gas passes through the flue in front of the main structure of the electrostatic precipitator and passes through the electric field area, the electric field discharges at the tip of the cathode line under the action of high-voltage direct current, causing the gas molecules to ionize and produce positive and negative ions. After the dust enters the electric field area, the positive and negative ions collide with the dust under the action of the electric field force and adsorb on the surface of the dust. Since the dust is charged when passing through the electric field area, most of the charged dust moves to the dust collecting electrode under the action of the electric field force and is collected. As the running time of the electrostatic precipitator increases, a thick layer of dust accumulates on the electrode surface of the electric field area. At this time, the electromagnetic vibrator arranged outside the top plate of the precipitator is used to knock the dust collecting electrode, so that the smoke with a certain thickness falls into the ash hopper below the electrostatic precipitator structure under the dual action of its own gravity and vibration, thereby achieving the effect of removing smoke from the air.

[0003] The working principle of the electromagnetic rapper is that when the coil is energized, a magnetic field is generated around the coil, and the rapping rod is lifted under the action of the magnetic field force. When it reaches a certain height, the magnetic field disappears due to the de-energization of the coil, and the rapping rod falls freely under the action of its own gravity. The rapping rod falls and hits the rapping rod, which then transmits the rapping force to the cathode and anode system devices inside the electrostatic precipitator, thereby achieving the purpose of vibration cleaning.

[0004] However, in actual use, it was found that by controlling the conduction and current of the rapping coil, the height at which the rapping rod moves in the rapping coil can be changed. The higher the height at which the rapping rod moves, the greater the impact force on the rapping rod during free fall, and the better the vibration effect. However, since the rapping rod is a consumable and relatively expensive, and the higher the height at which the rapping rod moves in the rapping coil, the more electrical energy it consumes. In addition, the dust collection distribution of the electric field plate is fine in the upper part and coarse in the lower part, and the adhesion of fine dust is greater than that of coarse dust. The fine dust with strong adhesion cannot be shaken off by a single impact of the rapping rod on the rapping rod. When the dust concentration entering the electrostatic precipitator is high, the fine dust located on the upper part of the electric field plate will form new aggregation before the next rapping as the interval of rapping time passes, resulting in a decrease in the dust collection efficiency of the electric field plate.

[0005] To this end, the present invention proposes an electrostatic precipitator top vibration electromagnetic drive module to solve the above problems. Summary of the invention

[0021] 1. The present invention squeezes the first piston through the first elastic member and the compressed gas in the first gas cylinder, so that the first piston moves and drives the first piston rod to move synchronously, so that when the lifting column moves downward in free fall, the first piston rod provides an initial thrust to the lifting column, so that the lifting column obtains a larger initial velocity, so that the lifting column falls quickly to collide with the collision rod, so that the vibration generated by the lifting column and the collision rod is larger, and a better vibration and cleaning effect is achieved.

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 those skilled in the art without creative work are within the scope of protection of the present invention.

[0035] Example 1

[0036] In the actual production process, it was found that since the rapping rod is a consumable and relatively expensive, and the higher the rapping rod moves in the rapping coil, the more electric energy it consumes, the rapping effect of the rapping rod being impacted by the free fall of the rapping rod is poor. This embodiment is specially invented to solve the above problems.

[0037] See also Figure 1 and Figure 3 As shown, an electromagnetic driving module for rapping the top of an electrostatic precipitator according to an embodiment of the present invention includes an equipment body 1, wherein the equipment body 1 includes a lifting part 2 for lifting and a fixing part 3 for fixing the equipment body 1 on the top of the electrostatic precipitator, and also includes an energy storage part 4 and a rapping part 5, wherein the installation of the equipment body 1 on the top of the electrostatic precipitator is a prior art and will not be elaborated herein.

[0038] See also Figure 3 and Figure 4As shown, the energy storage part 4 includes a first gas cylinder 41 arranged in the lifting part 2, a first piston 42 is sealingly and slidably connected in the first gas cylinder 41, one end of the first piston 42 is fixedly connected to a first piston rod 43, and a first elastic member 44 is arranged in the first gas cylinder 41, wherein the first elastic member 44 is a spring, and the two ends of the first elastic member 44 are respectively connected to the inner wall of the first gas cylinder 41 and one end of the first piston 42;

[0039] See also Figure 3 As shown, the rapping part 5 includes a collision rod 51 arranged in the fixed part 3, and the lifting part 2 includes a shell 21. A guide sleeve 22 is fixedly connected in the shell 21. The outer wall of the guide sleeve 22 is sleeved with a coil 23. A lifting column 24 is slidably connected in the guide sleeve 22. The bottom end of the lifting column 24 is movably connected to the collision rod 51. The first air cylinder 41 is fixed to the inner top of the guide sleeve 22. One end of the second piston rod 54 extends out of the collision rod 51 and is movably connected to the bottom end of the lifting column 24. Figure 2 As shown, a controller 25 is fixedly connected to the outer wall at the bottom end of the shell 21, wherein the controller 25 is a prior art and will not be elaborated herein. The controller 25 is electrically connected to the coil 23, and the fixing part 3 includes a fixing frame 31, a positioning tube 32 is arranged at the bottom of the fixing frame 31, and the end of the collision rod 51 away from the guide sleeve 22 is fixed in the positioning tube 32.

[0040] When in use, the coil 23 is supplied with direct current through the controller 25, so that the lifting column 24 moves upward in the guide sleeve 22. When the lifting column 24 moves to contact with the first piston rod 43, the lifting column 24 continues to rise, and the lifting column 24 squeezes the first piston rod 43 while rising. At this time, the first piston rod 43 drives the first piston 42 to move in the first gas cylinder 41. The first piston 42 squeezes the first elastic member 44 while moving in the first gas cylinder 41. At the same time, the gas at the bottom of the first gas cylinder 41 is compressed. When the first elastic member 44 is compressed to the maximum limit, at the same time, the controller 25 cuts off the power to the coil 23. When the power is cut off, the lifting column 24 freely falls downward in the guide sleeve 22. The first elastic member 44 in the first gas cylinder 41 squeezes the first piston 42, and the compressed gas in the first gas cylinder 41 located at the first elastic member 44 expands and further squeezes the first piston 42. The first piston 42 is squeezed by the first elastic member 44 and the compressed gas in the first gas cylinder 41, so that the first piston 42 moves and drives the first piston rod 43 to move synchronously, so that when the lifting column 24 moves downward in free fall, the first piston rod 43 provides an initial thrust to the lifting column 24, so that the lifting column 24 obtains a larger initial velocity, so that the lifting column 24 falls quickly to collide with the collision rod 51, so that the vibration generated by the lifting column 24 and the collision rod 51 is greater, and a better vibration and cleaning effect is achieved.

[0041] Example 2

[0042] In actual use, it is found that the lifting column 24 is provided with a preliminary thrust by the first piston rod 43 alone, so that the lifting column 24 obtains a larger initial velocity, so that the lifting column 24 falls quickly to collide with the collision rod 51, so that the vibration generated by the lifting column 24 and the collision rod 51 is larger, and the problem of low vibration efficiency still exists. Since the dust collection distribution of the electric field plate is fine dust particle size at the top and coarse dust particle size at the bottom, the adhesion of fine dust is greater than that of coarse dust. The fine dust with large adhesion cannot be shaken off by a single impact of the lifting column 24 on the collision rod 51. When the dust concentration entering the electrostatic precipitator is high, the fine dust located on the upper part of the electric field plate will generate new aggregation before the next vibration as the interval of the vibration time increases, resulting in a decrease in the dust collection efficiency of the electric field plate. For this reason, further improvements are made on the basis of the above embodiments.

[0043] See also Figure 3 and Figure 5 As shown, the inner top of the collision rod 51 is fixedly connected to the second gas cylinder 52, the second gas cylinder 52 is sealed and slidably connected to the second piston 53, the two ends of the second piston 53 are respectively fixedly connected to the second piston rod 54 and the third piston rod 55, and the outer wall of the third piston rod 55 in the second gas cylinder 52 is sleeved with a second elastic member 56, wherein the second elastic member 56 is a spring, and the two ends of the second elastic member 56 are respectively connected to the inner bottom of the second gas cylinder 52 and one end of the second piston 53. Figure 3 and Figure 4 The bottom of the second gas cylinder 52 near one end of the third piston rod 55 is fixedly connected to the limit ring 513, and the end of the third piston rod 55 extending out of the limit ring 513 is fixedly connected to the fixing member 58. Figure 8 Two placement grooves 581 are provided in the fixing member 58, and a limit block 582 is arranged between the two placement grooves 581. The two placement grooves 581 are both rotatably connected with clamping blocks 59, and the two clamping blocks 59 are arranged in a symmetrical distribution state with respect to the limit blocks 582. The two clamping blocks 59 are fixedly connected with a fixing column 510 on the side close to each other, and the ends of the two fixing columns 510 close to each other are fixedly connected with the limit column 511, and the outer walls of the two limit columns 511 are jointly sleeved with a third elastic member 512, and the two ends of the third elastic member 512 are respectively connected with the ends of the two fixing columns 510 close to each other. Figure 6 and Figure 7The inner bottom of the collision rod 51 is fixedly connected to a support ring 514, and a collision column 515 is fixedly connected inside the support ring 514. The top of the collision column 515 is movably connected to a first movable column 516, and the top of the first movable column 516 is fixedly connected to a second movable column 517. The outer wall of the first movable column 516 is sleeved with a fourth elastic member 518, wherein the fourth elastic member 518 is a spring, and the two ends of the fourth elastic member 518 are respectively connected to the top of the support ring 514 and the bottom of the second movable column 517, the top of the second movable column 517 is fixedly connected to a connecting column 519, and the top of the connecting column 519 is fixedly connected to a clamping disk 520 that cooperates with the two clamping blocks 59, and a conical hole for guiding the two clamping blocks 59 is opened in the limit ring 513, wherein the large diameter of the conical hole is close to the two clamping blocks 59.

[0044] When used on the basis of the above embodiment, the lifting column 24 falls rapidly due to the power failure of the coil 23, and hits the second piston rod 54. The second piston rod 54 moves while driving the second piston 53 to move in the second gas cylinder 52. The second piston 53 moves rapidly to squeeze the second elastic member 56. At the same time, the gas at the second elastic member 56 in the second gas cylinder 52 is compressed. At the same time, the second piston 53 squeezes the second elastic member 56 while driving the third piston rod 55 to move downward. The third piston rod 55 moves downward while driving the fixing member 58 to move. At the same time, the fixing member 58 drives the two clamping blocks 59 to squeeze the clamping plate 520. When the two clamping blocks 59 squeeze the clamping plate 520, the bottom ends of the two clamping blocks 59 located at the clamping plate 520 move away from each other and tilt. At the same time, the third elastic member 512 is squeezed and compressed by the two fixed columns 510. When the second elastic member 56 is compressed to the maximum limit position by the second piston 53, the lifting column 24 falls rapidly to hit the collision rod 51. At the same time, the bottom ends of the two clamping blocks 59 clamp the side and bottom edges of the clamping plate 520. At the same time, the third elastic member 512 located between the two fixed columns 510 relaxes, so that the two clamping blocks 59 fit the side walls of the limit block 582.

[0045] When the controller 25 supplies direct current to the coil 23 again, the lifting column 24 moves upward in the guide sleeve 22. At the same time, the second elastic member 56 relaxes and squeezes the second piston 53 to move upward. At the same time, the compressed gas at the second elastic member 56 in the second gas cylinder 52 further squeezes the second piston 53. The second piston 53 moves upward and drives the second piston rod 54 to move upward. The second piston rod 54 moves upward and squeezes the lifting column 24, providing a thrust for the lifting column 24 to move upward, so that the lifting column 24 can move upward quickly through the thrust when the coil 23 is energized.

[0046] The second piston 53 moves upward by the expansion and contraction of the second elastic member 56, and at the same time, the compressed gas at the second elastic member 56 in the second gas cylinder 52 further squeezes the second piston 53, and the second piston 53 moves upward while driving the third piston rod 55 upward, and the third piston rod 55 moves upward while driving the fixing member 58 upward, and the fixing member 58 moves upward while driving the two clamping blocks 59 and the clamping plate 520 upward, and the clamping plate 520 moves upward while driving the connecting column 519, the second movable column 517 and The first movable column 516 moves upward, and while the first movable column 516 moves upward, the fourth elastic member 518 relaxes to support the second movable column 517. When the two clamping blocks 59 move into the limiting ring 513, due to the tapered hole in the limiting ring 513, while the two clamping blocks 59 move upward in the limiting ring 513, the ends of the two clamping blocks 59 that contact the limiting ring 513 are guided by the limiting ring 513, so that the ends of the two clamping blocks 59 located in the limiting ring 513 are close to each other. At the same time, the fixing When the member 58 drives the two clamping blocks 59 to move to the maximum limit position in the limiting ring 513, the distance between one end of the two clamping blocks 59 located in the limiting ring 513 is the shortest. At the same time, the third elastic member 512 located between the two fixed columns 510 is compressed. At this time, one end of the two clamping blocks 59 located on both sides of the clamping plate 520 moves away from each other. When one end of the two clamping blocks 59 located on the clamping plate 520 completely leaves the clamping plate 520, the first movable column 516, the second movable column 517, the connecting column 519 together with the clamping The disk 520 falls freely under the action of its own gravity, and the first movable column 516 falls rapidly to hit the collision column 515. At the same time, the second movable column 517 squeezes the fourth elastic member 518. After repeated compression and relaxation of the fourth elastic member 518, the first movable column 516 hits the collision column 515 repeatedly under the action of the fourth elastic member 518 after falling rapidly to hit the collision column 515, thereby achieving multiple vibrations, thereby shaking off fine dust with strong adhesion and improving the efficiency of electric field dust collection vibration.

[0047] In summary, while the lifting column 24 moves upward in the guide sleeve 22, the second piston 53 moves upward by the expansion and contraction of the second elastic member 56. At the same time, the compressed gas at the second elastic member 56 in the second gas cylinder 52 further compresses the second piston 53. When the second piston 53 moves upward, it drives the second piston rod 54 to move upward. When the second piston rod 54 moves upward, it squeezes the lifting column 24, providing a thrust for the lifting column 24 to move upward, so that the lifting column 24 moves upward quickly by the thrust when the coil 23 is energized. The second piston 53 moves upward by the expansion and contraction of the second elastic member 56. At the same time, the compressed gas at the second elastic member 56 in the second gas cylinder 52 further compresses the second piston 53. When the third piston rod 55 moves upward, it drives the fixing member 58 to move. When component 58 drives the two clamping blocks 59 to move to the maximum limit position in the limit ring 513, and one end of the two clamping blocks 59 is completely separated from the clamping plate 520, the first movable column 516, the second movable column 517, the connecting column 519 and the clamping plate 520 fall freely under the action of their own gravity, and the first movable column 516 falls rapidly to hit the collision column 515, and at the same time, the second movable column 517 squeezes the fourth elastic component 518. After repeated compression and relaxation of the fourth elastic component 518, at the same time, after the first movable column 516 falls rapidly to hit the collision column 515, it repeatedly hits the collision column 515 under the action of the fourth elastic component 518, thereby achieving multiple vibrations, so that fine dust with strong adhesion can be shaken off, thereby improving the efficiency of electric field dust collection and vibration cleaning.

[0048] Example 3

[0049] In actual use, it is found that when the lifting column 24 moves upward in the guide sleeve 22, the second piston 53 moves upward through the expansion and contraction of the second elastic member 56. At the same time, the compressed gas at the second elastic member 56 in the second gas cylinder 52 further squeezes the second piston 53. When the second piston 53 moves upward, it drives the second piston rod 54 to move upward. Since the second elastic member 56 expands slowly, the second piston 53 moves upward slowly. At the same time, the second piston 53 drives the third piston rod 55 and the fixing member 58 to move upward slowly, resulting in the lifting column 24 falling rapidly to collide with the collision rod 51 when the fixing member 58 drives the two clamping blocks 59 to move to the maximum limit position in the limit ring 513. Further improvements are made on the basis of the above embodiments.

[0050] See also Figure 4 and Figure 5 As shown, a first connecting hole 45 is formed on the side wall of the first gas cylinder 41 away from the first piston rod 43, and a second connecting hole 57 is formed on the side wall of the second gas cylinder 52 away from the second piston rod 54. The first connecting hole 45 is connected to the second connecting hole 57 through a pipeline. Figure 1 and Figure 3An escape hole corresponding to the second communication hole 57 is opened on one side outer wall of the collision rod 51 and the positioning tube 32 , and an escape hole corresponding to the first communication hole 45 is opened on one side outer wall of the shell 21 .

[0051] When used on the basis of the above embodiment, when the controller 25 passes direct current through the coil 23, the lifting column 24 moves upward in the guide sleeve 22, and when the lifting column 24 moves to contact with the first piston rod 43, the lifting column 24 continues to rise, and the lifting column 24 squeezes the first piston rod 43 while rising. At this time, the first piston rod 43 drives the first piston 42 to move in the first gas cylinder 41, and the first piston 42 squeezes the first elastic member 44 while moving in the first gas cylinder 41. At the same time, the gas located at the bottom of the first gas cylinder 41 is compressed, and the compressed gas enters the second connecting hole 57 through the first connecting hole 45 and the pipeline, and the compressed gas enters the inner cavity of the second gas cylinder 52 through the second connecting hole 57. When the second elastic member 56 relaxes and squeezes the second piston 53 to move upward, the compressed gas entering the inner cavity of the second gas cylinder 52 through the second connecting hole 57 presses the second piston 53 upward. The plug 53 is further squeezed, so that the second piston 53 moves upward rapidly and drives the third piston rod 55 to move upward. The third piston rod 55 moves upward and drives the fixing piece 58 to move. The fixing piece 58 drives the two clamping blocks 59 to move rapidly to the maximum limit position in the limit ring 513. One end of the two clamping blocks 59 is completely separated from the clamping plate 520, so that before the lifting column 24 falls rapidly to hit the collision rod 51, the first movable column 516, the second movable column 517, the connecting column 519 and the clamping plate 520 fall freely under the action of their own gravity, and the first movable column 516 falls rapidly to hit the collision column 515. After the first movable column 516 falls rapidly to hit the collision column 515, it repeatedly hits the collision column 515 under the action of the fourth elastic member 518, thereby realizing multiple staggered vibrations to further effectively clean the dust.

[0052] In summary, while the lifting column 24 moves upward to squeeze the first piston rod 43, the gas at the bottom of the first gas cylinder 41 is compressed, and the compressed gas enters the second connecting hole 57 through the first connecting hole 45 and the pipeline, and the compressed gas enters the inner cavity of the second gas cylinder 52 through the second connecting hole 57. When the second elastic member 56 relaxes and squeezes the second piston 53 to move upward, the compressed gas entering the inner cavity of the second gas cylinder 52 through the second connecting hole 57 further squeezes the second piston 53, so that the second piston 53 moves upward quickly, driving the third piston rod 55 to move upward, and the fixing member 58 drives the two clamping blocks 59 to move upward. The limiting ring 513 moves quickly to the maximum limit position, and one end of the two clamping blocks 59 completely detaches from the clamping plate 520, so that before the lifting column 24 falls quickly to hit the collision rod 51, the first movable column 516, the second movable column 517, the connecting column 519 and the clamping plate 520 fall freely under the action of their own gravity, and the first movable column 516 falls quickly to hit the collision column 515. After the first movable column 516 falls quickly to hit the collision column 515, it repeatedly hits the collision column 515 under the action of the fourth elastic member 518, thereby achieving multiple staggered vibrations to further effectively clean the dust.
