Description

Technical Field

[0001] This utility model relates to a vibratory dust removal device for an electrostatic precipitator. Background Technology

[0002] An electrostatic precipitator is an environmental protection device that uses electrostatic mechanics to separate and remove dust from industrial flue gas, thereby significantly reducing the amount of dust emitted into the atmosphere, improving environmental pollution and air quality.

[0003] In existing technologies, the electrode plates of the electrostatic precipitator need to be periodically vibrated to remove dust. Vibration of the electrode plates inside the electric field of the electrostatic precipitator is generally performed from the bottom or top. However, regardless of the method, the vibrating hammer is mounted on a vibrating shaft, which directly drives the hammer to complete the vibration. But those skilled in the art have found the following problems in actual use: First, with the hammer mounted on the shaft, the shaft is easily deformed or bent rapidly under the influence of the hammer during prolonged vibration, leading to a rapid depletion of its lifespan. Second, once the shaft deforms or bends, it cannot accurately strike the hammer at the impact point, potentially damaging the electrode plates and shortening the service life of the electrostatic precipitator. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a rapping dust removal device for electrostatic precipitators.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A rapping dust removal device for an electrostatic precipitator includes an electrode plate located inside the electrostatic precipitator, a plurality of striking mechanisms equidistantly installed above the electrode plate and on the same straight line, and a prying mechanism fixedly installed to the internal frame of the electrostatic precipitator for driving the striking mechanisms to operate.

[0007] The striking mechanism includes a support base fixed to the electrode plate by bolts, an L-shaped striking hammer hinged to the support base, a striking post located below the L-shaped striking hammer and fixed to the electrode plate by bolts, and a return spring connected at one end to the L-shaped striking hammer and at the other end to the striking post.

[0008] The actuation mechanism includes a gearbox fixedly installed inside the electrostatic precipitator frame, a drive motor mounted on the gearbox and connected to the gearbox at its output end, a drive shaft extending from the output end of the drive motor, a lever fixedly connected to and parallel to the drive shaft, a driven shaft fixedly installed at the other end of the lever and aligned with the drive shaft, and a driven shaft mounting base with a built-in bearing housing fixedly installed inside the electrostatic precipitator frame.

[0009] Preferably, the L-shaped hammer includes an L-shaped hammer body, a hinge shaft passing through the right-angle portion of the L-shaped hammer body, a force-receiving arm perpendicular to the electrode plate for contacting the lever, a striking arm parallel to the electrode plate and located at the lower end of the L-shaped hammer body, and a hammer head integrally formed at the lower end of the striking arm and integrally formed with the force-receiving arm.

[0010] Furthermore, the hammerhead is a round hammerhead.

[0011] Furthermore, a spring retainer is welded to the end of the hammerhead.

[0012] Preferably, the driven pile is welded with supporting ribs arranged around the driven pile as the center.

[0013] Preferably, the driven pile is welded with a fastening lug with a round hole.

[0014] Preferably, a first connecting plate and a second connecting plate are vertically welded to both ends of the lever.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The lever in the actuation mechanism works in conjunction with the L-shaped hammer to not only achieve dust removal by vibrating the electrode plate, but also to prevent the lever from bending and deforming due to the influence of the L-shaped hammer. After the drive motor adjusts the torque through the gearbox, it drives the lever to rotate, which can continuously and stably carry out the striking operation, ensuring that the electrostatic precipitator can carry out dust removal operations without interruption during long-term operation.

[0017] 2. Utilizing the combined effects of gravity and a return spring, the L-shaped hammer achieves greater precision and efficiency during impact. The combination of the hammer's weight and the spring's tension ensures uniform and efficient energy output with each strike, enhancing the device's durability and lifespan. Specifically, the support rib design improves the structural stability of the pile, preventing deformation caused by frequent impacts during long-term operation and enhancing the pile's durability. The return spring ensures that the L-shaped hammer quickly and accurately returns to its original position after each strike, maintaining a stable working rhythm and preventing low work efficiency due to untimely return.

[0020] Figure 3 for Figure 2 Structural diagram of the striking mechanism. Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0022] Example

[0023] like Figure 1-3 As shown, a rapping dust removal device for an electrostatic precipitator includes an electrode plate 1 located inside the electrostatic precipitator, a plurality of striking mechanisms 2 equidistantly installed above the electrode plate 1 and on the same straight line, and a prying mechanism 3 fixedly installed to the internal frame of the electrostatic precipitator for driving the striking mechanisms 2 to operate.

[0024] The striking mechanism 2 includes a support base 21 fixed to the electrode plate 1 by bolts, an L-shaped striking hammer 22 hinged to the support base 21, a striking post 23 located below the L-shaped striking hammer 22 and fixed to the electrode plate 1 by bolts, and a return spring 24 connected at one end to the L-shaped striking hammer 22 and at the other end to the striking post 23.

[0025] The actuation mechanism 3 includes a gearbox 31 fixedly installed inside the frame of the electrostatic precipitator, a drive motor 32 mounted on the gearbox 31 and connected to the gearbox 31 at its output end, a drive shaft 33 extending from the output end of the drive motor 32, a lever 34 fixedly connected to and parallel to the drive shaft 33, a driven shaft 35 fixedly installed at the other end of the lever 34 and on the same straight line as the drive shaft 33, and a driven shaft mounting seat 36 with a built-in bearing housing fixedly installed inside the frame of the electrostatic precipitator.

[0026] In the specific structure of the striking mechanism 2, the L-shaped striking hammer 22 includes an L-shaped striking hammer body 221, a hinge shaft 222 passing through the right-angle portion of the L-shaped striking hammer body 221, a force-receiving arm 223 perpendicular to the electrode plate 1 for contacting the lever 34, a striking arm 224 parallel to the electrode plate 1 and located at the lower end of the L-shaped striking hammer body 221, and a hammer head 225 integrally formed at the lower end of the striking arm 224 and integrally formed with the force-receiving arm 223. Specifically, the right-angle portion of the L-shaped striking hammer body 221 is close to the support base 21, and by passing through the hinge shaft 222, the L-shaped striking hammer 22 can be movably mounted on the support base 21, and the L-shaped striking hammer 22 can rotate around the hinge shaft 222 as the axis, facilitating the lifting and rotation of the lever 34 during rotation.

[0027] A spring retainer 226 is welded to the end of the hammer head 225, specifically to facilitate the fastening of the reset spring 24.

[0028] In this embodiment, the hammerhead 225 is a circular hammerhead.

[0029] The impact pile 23 is welded with supporting ribs 231 arranged around the impact pile 23. Specifically, this can improve the structural stability of the impact pile 23, enabling the impact pile 23 to withstand frequent impacts from the L-shaped impact hammer 22 without deformation.

[0030] The impact pile 23 is welded with a fastening lug 231 with a round hole, specifically for the convenient fastening and installation of the return spring 24.

[0031] In the specific structure of the actuation mechanism 3, the two ends of the lever 34 are vertically welded with a first connecting plate 341 and a second connecting plate 342. Specifically, the lever 34 is connected and fixed to the drive shaft 33 through the first connecting plate 341 and to the driven shaft 35 through the second connecting plate 342. The drive motor 32 reduces the speed and increases the torque through the reduction gearbox 31, thereby driving the lever 34 to rotate and draw a circle through the drive shaft 33.

[0032] It should be further explained that, in actual operation, the drive motor 32 is decelerated and the torque is increased by the reduction gearbox 31, thereby driving the lever 34 to rotate counterclockwise in a circle via the drive shaft 33. During the rotation, the lever 34 moves the force arm 223 of the L-shaped hammer 22, causing the L-shaped hammer 22 to rotate clockwise. When the lever 34 rotates to disengage from the force arm 223, the L-shaped hammer 22 rotates counterclockwise to reset under the combined force of the weight of the hammer head 225 and the rebound pull of the return spring 24. At this time, the hammer head 225 accurately strikes the impact pile 23, causing the electrode plate 1 to vibrate and achieve dust removal.

[0033] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
