Description

Technical Field

[0001] This invention belongs to the technical field of electrostatic precipitators, specifically relating to a vibration mechanism for preventing caking in the ash hopper of an electrostatic precipitator in a coal-fired power plant. Background Technology

[0002] Flue gas dust removal in coal-fired power plants is a core component for controlling particulate matter emissions and ensuring air quality. Electrostatic precipitators (ESPs), with their advantages of handling large volumes of flue gas, low operating resistance, and reliable dust removal efficiency, have become standard flue gas purification equipment for domestic coal-fired power generating units. The ash hopper is a key ash storage and discharge component at the bottom of the ESP, used to collect fly ash detached from the electrode plates and wires after cleaning, and continuously conveying the fly ash to the ash conveying system via a bottom discharge device. In actual production, fly ash generally contains unburned carbon, sulfates, and soluble components. Under conditions of low unit load operation, flue gas temperature below the acid dew point, or high flue gas humidity, fly ash easily absorbs moisture and adheres, continuously accumulating on the ash hopper cone wall and at corners. Therefore, ash hoppers are generally equipped with a rapping mechanism to periodically strike the hopper wall, breaking down the ash layer structure, promoting smooth fly ash descent, and ensuring continuous and stable operation of the dust removal system.

[0003] Existing electrostatic precipitators in coal-fired power plants mostly use externally fixed rapping devices for their ash hoppers. Since the effective range of action is limited to the area around the rapping point and the force is attenuated as it is transmitted along the hopper wall, a dense caking layer may still form after long-term operation. Therefore, we propose an anti-caking rapping mechanism for the ash hopper of electrostatic precipitators in coal-fired power plants. Summary of the Invention

[0004] The purpose of this invention is to provide a vibration mechanism for preventing caking in the ash hopper of an electrostatic precipitator in a coal-fired power plant, which aims to solve the problems mentioned in the background art.

[0009] As a preferred embodiment of the anti-caking vibration mechanism for the ash hopper of the electrostatic precipitator in a coal-fired power plant according to the present invention, the second transmission component includes two gears fixedly connected to the outer wall of the rotating rod, a rack meshing with the gears is fixedly connected to the outer wall of the guide seat, and nine rubber strips are fixedly connected to the outer wall of the rotating rod.

[0010] As a preferred embodiment of the anti-caking vibration mechanism for the ash hopper of the electrostatic precipitator in a coal-fired power plant according to the present invention, the elastic component includes a trigger seat that is slidably connected to the inner wall of the displacement collar and fixedly connected to the outer wall of the irregular rod and rotatably connected to the inner wall of the winding reel. The inner wall of the trigger seat is provided with a sliding groove, and a locking block that is slidably connected to the inner wall of the locking groove is slidably connected to the inner wall of the locking slot. An inner rod that is slidably connected to the inner wall of the locking block is fixedly connected to the inner wall of the trigger seat. The inner rod passes through the locking block to the outer wall. A second return spring is provided between the locking block and the trigger seat.

[0011] As a preferred embodiment of the anti-caking vibration mechanism for the ash hopper of the electrostatic precipitator in a coal-fired power plant according to the present invention, the triggering component includes a pulley limiting block fixedly connected to the outer wall of the slide rod, a pulley rotatably connected to the inner wall of the pulley limiting block, a guide pulley limiting block fixedly connected to the outer wall of the guide seat on the right side, and a guide pulley rotatably connected to the outer wall of the guide pulley limiting block and slidably connected to the pull rope.

[0012] As a preferred embodiment of the anti-caking vibration mechanism for the ash hopper of the electrostatic precipitator in a coal-fired power plant according to the present invention, the reciprocating assembly includes a shaft seat fixedly connected to the inner wall of the connecting seat, a coupling frame rotatably connected to the outer wall of the shaft seat, and a limiting ring rotatably connected to the inner wall of the coupling frame and rotatably connected to the outer wall of the reciprocating sleeve rod.

[0013] As a preferred embodiment of the anti-caking vibration mechanism for the ash hopper of the electrostatic precipitator in a coal-fired power plant according to the present invention, the third transmission component includes two worm gear limiting blocks fixedly connected to the inner wall of the connecting seat. The inner walls of the two worm gear limiting blocks are rotatably connected to worm gears that mesh with worms. The outer walls of the worm gears are fixedly connected to two convex shaft disks. The outer walls of the two convex shaft disks are rotatably connected to connecting rods that are rotatably connected to the outer wall of the connecting shaft frame.

[0014] A vibration mechanism for preventing caking in the ash hopper of an electrostatic precipitator in a coal-fired power plant includes the following steps: When the motor is started, it will indirectly drive the rotating rod to move downward along the guide groove. During this period, the gear is driven by the rack, which indirectly causes the nine rubber strips to rotate around the rotating rod and beat the ash hopper; When the wedge block contacts the pulley, the first return spring will indirectly cause the rotating rod to return to its original position. When the motor starts, it indirectly causes the agitator roller to rotate and move back to its original position to the left and right. Once the experiment is complete, simply turn off the motor.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention features a guide seat. When the rotating rod moves up and down along the guide groove of the guide seat with the displacement block, the gear and rack mesh to drive the nine rubber strips to rotate synchronously and continuously strike the ash hopper wall. This achieves the effect of full-coverage vibration by moving along the height direction of the ash hopper cone surface during the vibration process, completely eliminating vibration blind spots and preventing the long-term accumulation of fly ash on the hopper wall to form a dense, hardened layer.

[0016] This invention incorporates an inclined block. As the winding reel pulls the displacement block downwards with its winding rope, the inclined block, upon contacting the pulley, pushes a sliding rod, causing the displacement collar to move axially. This disengages the locking block from the winding reel's slot, and a first return spring then rapidly moves the displacement block and rotating rod upwards to reset. This design allows the rubber strip to rotate and vibrate against the bin wall during the rotation of the rotating rod, improving the efficiency of fly ash layer removal and effectively ensuring a smooth and continuous ash unloading process from the ash hopper.

[0017] This invention incorporates a worm gear that drives a shaped rod to rotate, which in turn drives a reciprocating sleeve and the worm gear to rotate synchronously. Simultaneously, the worm gear meshes with a worm wheel to rotate, which in turn drives a connecting frame to oscillate back and forth via a cam disc and a connecting rod. This traction causes the reciprocating sleeve to move back and forth along the axial direction, thereby directly loosening the caking fly ash accumulated in the cone section. This prevents bridging and blockage of fly ash during unloading, further improving unloading efficiency. Attached Figure Description

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Example

[0030] Reference Figure 1-9 This is the first embodiment of the present invention, which provides a vibration mechanism for preventing caking in the ash hopper of an electrostatic precipitator in a coal-fired power plant. The mechanism includes a displacement component symmetrically arranged along the outer wall of the ash hopper's conical surface. The entire structure is externally mounted, not intruding into the ash storage space inside the ash hopper, forming the foundation for the lifting and lowering of the vibration component and the transmission of power. This provides a stable linear displacement trajectory and a reliable power input path for the vibration action on the outer wall, enabling the vibration structure to cover the entire hopper wall area from the upper straight section connection to the lower conical opening. This completely eliminates the blind spot in the height direction of fixed-installation vibration devices. The entire structure maintains a reasonable gap with the outer wall of the ash hopper, ensuring smooth and unobstructed displacement while avoiding additional interference with the vibration action. Furthermore, the external layout facilitates daily inspections and component replacement, allowing maintenance to be completed without entering the ash hopper. It is the core load-bearing structure for achieving full-conical-surface full-coverage vibration function.

[0031] The power assembly 17 is fixedly installed on the outer wall of the connecting seat 16, serving as the sole power source for all actions. The motor 171 is vertically mounted and closely fitted to the outer wall of the connecting seat 16. The motor body is fixedly connected to the outer wall of the connecting seat 16. The output shaft is rigidly connected to the transmission rod 172 via a coupling, which can stably output continuous and uniform rotational torque to synchronously drive the two mechanisms of outer wall vibration and internal blockage clearing. This ensures that the vibration and blockage clearing actions are continuously synchronized, avoiding the timing deviation and mismatch problems that are prone to occur with multiple power source drives. At the same time, the single power source design can also reduce the overall energy consumption and subsequent maintenance costs of the equipment.

[0032] Furthermore, the first transmission component 18 is embedded in the internal cavity of the connecting seat 16, undertaking the core role of power diversion and speed matching. The worm gear 181 is fixed coaxially along the vertical direction to the outer wall of the transmission rod 172, and rotates synchronously and uniformly with the transmission rod 172. The irregular rod 182 is coaxially fixed to the top end face of the worm gear 181. There are two protrusions on the rod body, which can form a circumferential limit to transmit torque with the matching components while allowing axial relative sliding. It can drive the upper winding component 19 to rotate circumferentially to realize rope winding and vibration lifting, and can also synchronously drive the internal unblocking component to complete the rotation and stirring action, realizing multi-path power diversion of a single power source.

[0033] The winding assembly 19 is located at the transmission connection position between the right displacement block and the trigger seat, and undertakes the traction and reset control function of the vibrating component. One end of the pull rope 191 is firmly fixed to the center position of the top end face of the displacement block 14, and the other end extends upward along the guide groove 13 of the guide seat 12 and is wound and fixed in the outer wall groove of the winding reel 192 after being reversed by the top reversing structure. The first reset spring 193 is sleeved inside the guide groove 13, and its upper and lower ends abut against the lower end face of the displacement block 14 and the inner wall of the guide seat 12, respectively. The inner wall of the winding reel 192 has a slot 194 that can be precisely matched with the elastic locking structure to realize the automatic switching between locking and unlocking of the winding state, and precisely control the complete lifting cycle of the downward traction and upward reset of the displacement block.

[0034] Preferably, the guide seats 12 are symmetrically arranged and fixed to corresponding positions on the outer walls of the two sides of the ash hopper 11. The guide groove 13 extends along the generatrix of the cone surface of the ash hopper 11. The inner wall of the groove is smoothed to reduce frictional resistance. The displacement block 14 is integrally embedded in the internal cavity of the guide groove 13. The outer wall and the inner wall of the groove maintain a precise fit gap. The rotating rod 15 is horizontally mounted between the two displacement blocks 14, spanning the entire cone surface of the ash hopper. Both ends are rotatably connected to the displacement blocks 14, which can fully ensure that the rotating rod 15 moves smoothly up and down along the cone surface, effectively avoiding problems such as skewing, jamming or shaking during the displacement process, ensuring that the rubber strip is accurately positioned and the force is uniform, and ensuring continuous and stable output of the rapping action.

[0035] It should be noted that the displacement component adopts a lifting linkage layout, which eliminates the need for a separate lifting drive device for the rapping structure. It can automatically complete the full stroke of the rapping component by relying solely on the rotational power output of the main transmission system and the matching spring reset structure. Automatic cycling can be achieved without the need for additional limit switches or electrical control components.

[0036] In operation, motor 171 drives transmission rod 172 to rotate, causing worm gear 181 and shaped rod 182 to rotate synchronously. Shaped rod 182 drives trigger seat 261 to rotate synchronously. Locking block 263 engages in the locking groove 194 of winding reel 192, causing winding reel 192 to rotate synchronously and wind up pull rope 191. After pull rope 191 is reversed by guide pulley 274, traction displacement block 14 slides downward along guide groove 13 of guide seat 12. The two displacement blocks 14 together drive rotating rod 15 to descend along the outer wall of ash hopper 11. During the descent, gear 211 on the outer wall of rotating rod 15 continuously meshes with rack 212 on the outer wall of guide seat 12, causing rotating rod 15 to rotate while descending. Rubber strip 213 on the outer wall of rotating rod 15 strikes the cone wall of ash hopper 11 in sequence with the rotation, applying impact vibration force to the fly ash slab layer attached to the hopper wall. Example

[0037] Reference Figure 1-9 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a vibrating component. The vibrating component is distributed along the entire outer wall of the conical surface of the ash hopper 11. With the horizontally arranged rotating rod 15 as the core bearing component, it integrates multiple functional structures such as self-rotation transmission, automatic triggering reset, and elastic clutch. It can simultaneously complete the circumferential knocking action while moving up and down along the height direction of the conical surface, forming a continuous and uniform full-coverage vibrating action on the hopper wall of the ash hopper 11. Through continuous impact vibration, it thoroughly breaks down the dense fly ash caking layer attached to the hopper wall, avoiding long-term accumulation and hardening of fly ash at the corners of the conical wall, and fundamentally eliminating the blind spots of limited range of action and force attenuation that exist in fixed-point vibrators.

[0038] Specifically, the second transmission component 21 is distributed between the two ends of the rotating rod 15 and the side wall of the corresponding side guide seat 12, and undertakes the transmission function of converting linear displacement into rotational vibration. The two gears 211 are coaxially fixed at the two ends of the rotating rod 15, and rise and rotate synchronously with the rotating rod 15. The rack 212 is fixed on the outer side wall of the guide seat 12 along the entire extension direction of the guide groove 13, and the tooth surface faces the gear side to maintain a precise meshing state.

[0039] Furthermore, nine rubber strips 213 are evenly arranged around the circumference of the rotating rod 15 with their striking ends facing the ash hopper 11. The continuous meshing of the gear 211 and the rack 212 can convert the linear lifting displacement of the rotating rod 15 into its own rotational motion, driving the rubber strips 213 to strike the hopper wall in sequence to form a uniform vibration effect. No additional independent rotation drive element is required throughout the process.

[0040] The trigger component 27 and the elastic component 26 together constitute an automatic reset clutch control structure. The slide bar limit seat 22 is fixed at the lower corresponding position on the outer wall of the ash hopper 11, providing support and limit for the slide bar to slide laterally. The slide bar 23 is horizontally inserted into the smooth internal channel of the slide bar limit seat 22, and can slide smoothly in the horizontal direction. The pulley 272 is installed at the end of the slide bar 23 through the pulley limit block 271 and is directly opposite the downward path of the inclined block 20. The guide pulley 274 is fixed to the top of the guide seat 12 through the guide pulley limit block 273 to provide reversing support for the pull rope. The elastic component 26 is embedded in the internal cavity of the displacement collar 25. The locking block 263 can slide smoothly along the slide groove 262 under the axial drive of the displacement collar 25, realizing precise engagement and quick disengagement with the locking groove 194, automatically switching between the winding traction and spring reset working states, ensuring the continuous and stable operation of the entire vibration cycle.

[0041] In use, the displacement block 14 drives the inclined block 20 to move downwards synchronously. When the inclined surface of the inclined block 20 contacts the pulley 272, the thrust of the inclined surface of the inclined block 20 pushes the pulley 272 away from the ash hopper 11. The pulley 272 pushes the slide rod 23 to slide along the slide rod limiting seat 22 through the pulley limiting block 271. The slide rod 23 drives the displacement collar 25 to move axially through the connecting strip 24. The displacement collar 25 drives the locking block 263 to slide along the slide groove 262 and compress the second return spring 265, causing the locking block 263 to disengage from the locking groove 194 of the winding reel 192. After the winding reel 192 loses its circumferential limit, it stops winding the pull rope 191. At this time, the compressed first return spring 193 releases its elasticity, pushing the displacement block 14 to quickly move upwards and reset along the guide groove 13. During the upward movement, the gear 211 meshes with the rack 212 again, causing the rotating rod 15 to rotate in the opposite direction, and the rubber strip 213 strikes the bin wall again. After the displacement block 14 is reset, the inclined block 20 disengages from the pulley 272, the second reset spring 265 pushes the locking block 263 to reset and re-engage into the slot 194, and the winding reel 192 rotates again with the trigger seat 261 to wind up and enter the next vibration cycle. Example

[0042] Reference Figure 1-9This is the third embodiment of the present invention. This embodiment provides a vibration mechanism for preventing fly ash caking in the ash hopper of a coal-fired power plant. The vibration mechanism includes a blockage-clearing component, which is built into the cone-shaped discharge core area inside the ash hopper. It directly acts on the discharge port where fly ash is most prone to accumulation and caking. Through a combined motion of rotational stirring and axial reciprocating movement, it directly loosens the caking structure from inside the fly ash and breaks down the adhesion force. This effectively eliminates the common fly ash bridging and arched blockage problems at the discharge port, and prevents fly ash that has been dislodged from the hopper wall from accumulating and blocking again at the discharge port. Combined with the external wall vibration component, it forms a dual anti-caking effect with internal and external synergy, comprehensively improving the ash discharge smoothness and operational stability of the ash hopper.

[0043] The reciprocating assembly 32 is located in the internal cavity of the connecting seat 16, and undertakes the transmission function of converting rotational motion into axial reciprocating motion. The bearing seat 321 is fixed to the corresponding position on the inner side wall of the connecting seat 16, providing a stable support fulcrum for the swing structure. The coupling frame 322 is hinged to the end of the bearing seat 321 to form a stable swing fulcrum. The limiting ring 323 is sleeved on the outer wall of the reciprocating sleeve 30 and hinged to the end of the coupling frame 322. It can pull the reciprocating sleeve without interfering with its own rotation. When the coupling frame 322 swings continuously around the bearing seat 321, the limiting ring 323 can pull the reciprocating sleeve 30 to move back and forth at a uniform speed along the axial direction, realizing the axial reciprocating disturbance effect of the agitator roller 31 and greatly expanding the axial action range of the loose fly ash inside.

[0044] Furthermore, the third transmission component 33 is arranged beside the worm 181 and forms a transmission connection with the reciprocating component 32, undertaking the function of motion mode conversion. Two worm wheel limiting blocks 331 are symmetrically fixed on both sides of the inner wall of the connecting seat 16, providing stable rotational support and axial limiting for the worm wheel. The worm wheel 332 is mounted between the two worm wheel limiting blocks 331 and maintains a precise meshing state with the worm 181. Two cam discs 333 are respectively fixed on the two end faces of the worm wheel 332, and the transmission shaft is eccentrically set on the disc surface.

[0045] Among them, the two ends of the connecting rod 334 are rotatably connected to the eccentric shaft of the cam disc 333 and the side rod of the connecting frame 322, respectively. It can stably convert the continuous circumferential rotation of the worm gear 332 into the reciprocating oscillation of the connecting frame 322, providing stable power for the axial displacement of the reciprocating sleeve rod. The reciprocating sleeve rod 30 is transversely inserted inside the cone section of the ash hopper 11 above the discharge port. The two ends of the rod body are sealed with the side wall of the ash hopper through the sealing bushing to achieve rotation and sliding sealing. Multiple sets of actuating rollers 31 are equidistantly arranged along the axial direction of the reciprocating sleeve rod 30, covering the main fly ash accumulation area above the discharge port.

[0046] Preferably, the roller body surface of the agitator roller 31 is provided with multiple axially raised ribs, which can effectively increase the contact area with fly ash and the cutting and crushing force. When it rotates synchronously with the reciprocating sleeve rod 30 and moves axially back and forth, it can fully agitate the fly ash at different depths around it, destroy the particle bonding structure of the plated layer from the inside, break up the agglomerated fly ash particles, and prevent the fly ash from forming a stable dense bridging structure at the discharge port.

[0047] It should be noted that the unblocking component and the outer wall rapping component share the same power source. Synchronous start-up and operation are achieved through the multi-directional power diversion of the worm gear 181. The two sets of actions, outer wall rapping and internal fly ash loosening, operate synchronously without interfering with each other. When the fly ash that is dislodged from the silo wall by vibration falls to the cone, it can be promptly guided to fall by the internal agitation structure. The two form a synergistic effect of internal and external linkage.

[0048] When in use, when the motor 171 drives the transmission rod 172 to rotate the worm gear 181, the worm gear 181 synchronously drives the shaped rod 182 to rotate. The non-circular cross section of the shaped rod 182 is adapted to the inner wall of the reciprocating sleeve rod 30, driving the reciprocating sleeve rod 30 to rotate synchronously. The agitator roller 31 on the outer wall of the reciprocating sleeve rod 30 agitates the fly ash at the discharge port inside the ash hopper 11 as it rotates. Simultaneously, the worm gear 181 meshes with the worm wheel 332, driving the worm wheel 332 to rotate around the worm wheel limiting block 331. The cam discs 333 at both ends of the worm wheel 332 rotate synchronously. The cam discs 333 drive the connecting rod 334 to perform planar motion through the eccentric shaft. The connecting rod 334 pulls the connecting frame 322 to swing back and forth around the shaft seat 321. The connecting frame 322 pulls the reciprocating sleeve 30 to slide axially back and forth along the irregular rod 182 through the limiting ring 323, so that the agitator roller 31 moves axially back and forth along the ash hopper 11 while rotating, forming a continuous disturbance to the fly ash in the cone of the ash hopper 11, destroying the slab structure, and preventing fly ash from bridging and blocking at the discharge port. Example

[0049] Reference Figure 1-9 This is the fourth embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a test method for an anti-caking rapping mechanism in the ash hopper of a coal-fired power plant electrostatic precipitator, which includes the following steps: When the motor 171 is started, the motor 171 will indirectly drive the rotating rod 15 to move downward along the guide groove 13. During this period, gear 211 is driven by rack 212, which indirectly causes nine rubber strips 213 to rotate around rotating rod 15 and beat ash hopper 11. When the inclined block 20 contacts the pulley 272, the first return spring 193 will indirectly cause the rotating rod 15 to return to its original position. When motor 171 starts, it indirectly causes the agitator roller 31 to rotate and move left and right back to its original position. The experiment is now complete. Simply turn off motor 171.
