Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, and in particular to a rotary electrostatic precipitator with centralized vibration. Background Technology

[0002] A centralized rapping rotary electrostatic precipitator is a device used for industrial waste gas purification, primarily for removing dust particles from gases. It can be used in various industrial fields, such as boiler flue gas and industrial furnace exhaust gas in power, metallurgy, chemical, and cement industries, and has good removal effects on dust with different properties and particle sizes.

[0003] In existing dust collectors, the vibration assembly and the anode plate operate independently and cannot work together. The vibration assembly typically follows a pre-set program or performs cleaning tasks at fixed intervals, unrelated to the rotation of the anode plate. For example, some traditional dust collectors rely on timers to trigger the vibration motor, performing a cleaning operation at fixed time intervals. However, in actual operation, even if the rotation state of the anode plate changes, the vibration assembly still operates according to its predetermined mode. This independent operating mode greatly limits the overall automation level of the device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotary electrostatic precipitator with centralized vibration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotary electrostatic precipitator with centralized vibration includes a precipitator housing. The precipitator housing contains an air inlet channel, a rotating chamber, and a collection chamber. A fan and a rotary motor are located outside the precipitator housing. A cathode wire is located within the air inlet channel. A rotating frame is located within the rotating chamber, and an anode plate is mounted on the rotating frame. A movable groove is located on the rotating frame, and a sliding rod is located within the movable groove. An impact frame is slidably mounted on the sliding rod via an elastic mechanism. A cavity is located inside the rotating frame, and a drive shaft and a transmission shaft are rotatably mounted within the cavity. An arc-shaped rack is located on the inner wall of the precipitator housing. The drive shaft is connected to the arc-shaped rack via a drive mechanism. The drive shaft and the transmission shaft are connected via a transmission mechanism. The transmission shaft and the impact frame are connected via a reciprocating meshing mechanism.

[0007] Preferably, the elastic mechanism includes a spring sleeved on the outside of the slide bar, with both ends of the spring connected to the outer wall of the impact frame and the inner wall of the movable groove, respectively.

[0008] Preferably, the active mechanism includes a meshing gear mounted on the drive shaft, and the meshing gear is designed to correspond to the arc-shaped rack.

[0009] Preferably, the transmission mechanism includes a drive gear mounted on a drive shaft, and the drive shaft is provided with a transmission gear that meshes with the drive gear.

[0010] Preferably, the reciprocating meshing mechanism includes an incomplete gear mounted on the transmission shaft, and the impact frame is provided with a spur rack corresponding to the incomplete gear.

[0011] Preferably, both the meshing gear and the incomplete gear are spherical gears, and both the driving gear and the transmission gear are bevel gears.

[0012] Preferably, the dust collector housing is provided with an movable opening that communicates with the collection chamber, and a movable box is provided inside the movable opening.

[0013] The beneficial effects of this utility model are:

[0014] 1. This technical solution innovatively integrates the operation of the vibration assembly with that of the anode plate. When the rotating frame rotates under the drive of a rotary motor, the impact frame rhythmically vibrates the anode plate through the active mechanism, transmission mechanism, and reciprocating meshing mechanism. The rotational state of the anode plate directly affects the operation of the vibration assembly, changing the traditional situation where the two are independent and achieving coordinated operation, greatly improving the targeting and effectiveness of dust removal.

[0015] 2. The entire system, based on the rotation of the rotating frame, automatically completes a series of processes from dust adsorption on the anode plate to rapping and cleaning. It eliminates the need for frequent manual intervention to adjust the operating parameters of the vibration components, reducing the possibility of human error. Regardless of the anode plate's operating state, the system automatically adjusts the vibration components according to its rotation, achieving true automated collaborative operation and meeting the demands of modern industry for efficient and intelligent dust removal equipment.

[0016] 3. Because the vibration components work in tandem with the anode plates, it ensures that the anode plates can be cleaned promptly and effectively under different operating conditions. This avoids dust accumulation that affects dust removal efficiency due to untimely cleaning, as well as anode plate wear caused by excessive cleaning. As a result, the dust collector's dust removal efficiency can be maintained at a stable high level, extending the equipment's service life and reducing maintenance costs. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A rotary electrostatic precipitator with centralized vibration includes a precipitator housing 1. The precipitator housing 1 contains an air inlet channel 4, a rotating chamber 7, and a collection chamber 8. A fan 2 and a rotary motor 3 are located outside the precipitator housing 1. A cathode wire 6 is located within the air inlet channel 4. A rotating frame 9 is located within the rotating chamber 7. An anode plate 10 is mounted on the rotating frame 9. A movable groove 13 is located on the rotating frame 9. A sliding rod 19 is located within the movable groove 13. An impact frame 14 is slidably mounted on the sliding rod 19 via an elastic mechanism. A cavity 18 is located inside the rotating frame 9. An active shaft 21 and a transmission shaft 16 are rotatably mounted within the cavity 18. An arc-shaped rack 12 is located on the inner wall of the precipitator housing 1. The active shaft 21 is connected to the arc-shaped rack 12 via an active mechanism. The active shaft 21 and the transmission shaft 16 are connected via a transmission mechanism. The transmission shaft 16 and the impact frame 14 are connected via a reciprocating meshing mechanism.

[0026] The elastic mechanism includes a spring 20 sleeved on the outside of the slide bar 19, with both ends of the spring 20 connected to the outer wall of the impact frame 14 and the inner wall of the movable groove 13, respectively. The elastic potential energy provided by the spring 20 enables the impact frame 14 to be dragged, ensuring that in the initial state, the outer wall of the impact frame 14 is in contact with the outer wall of the anode plate 10.

[0027] The active mechanism includes a meshing gear 11 mounted on the active shaft 21, which corresponds to the arc-shaped rack 12. The transmission mechanism includes an active gear 23 mounted on the active shaft 21, and a transmission gear 22 meshing with the active gear 23 on the transmission shaft 16. Both the meshing gear 11 and the incomplete gear 17 are spur gears, while both the active gear 23 and the transmission gear 22 are bevel gears. Based on this design of multiple gears, when the rotating frame 9 rotates under the drive of the rotary motor 3, the meshing gear 11 rotates under the action of the arc-shaped rack 12, driving the active shaft 21 to rotate. The active shaft 21, in conjunction with the active gear 23 and the transmission gear 22, drives the transmission shaft 16 to rotate. The transmission shaft 16, in conjunction with the incomplete gear 17, drives the spur rack 15 to move, thereby causing the impact frame 14 to move on the slide rod 19 and drag the spring 20.

[0028] The reciprocating meshing mechanism includes an incomplete gear 17 mounted on the drive shaft 16, and a rack 15 corresponding to the incomplete gear 17 is provided on the impact frame 14. Because of the design of the incomplete gear 17, there are times when it loses meshing with the rack 15.

[0029] The dust collector housing 1 has an opening that communicates with the collection chamber 8, and an movable box 5 is located inside the opening. The movable box 5 can collect dust that falls from the anode plate 10. As shown in the figure, the movable box 5 is also equipped with a handle, which can be grasped to remove the movable box 5, thereby facilitating the treatment of the dust collected inside.

[0030] Components not specifically described in this utility model are all standard parts and can be purchased from the market. The specific connection methods of each component adopt mature methods in the prior art, and will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0031] When using this utility model:

[0032] Dust-laden gas enters: The fan 2 generates suction, causing the dust-laden gas to enter the dust collector housing 1 through the inlet channel 4. The cathode wire 6 in the inlet channel 4 is energized with high voltage to generate corona discharge, which charges the dust particles in the dust-laden gas.

[0033] Dust collection: The rotary motor 3 drives the rotating frame 9 to rotate, and the anode plate 10 on the rotating frame 9 rotates accordingly. Charged dust is adsorbed onto the anode plate 10 under the action of the electric field force.

[0034] Vibration cleaning: During the rotation of the rotating frame 9, the meshing gear 11 mounted on the drive shaft 21 meshes with the arc-shaped rack 12 on the inner wall of the dust collector housing 1, driving the drive shaft 21 to rotate. The drive shaft 21 drives the transmission shaft 16 to rotate through the drive gear 23 and the transmission gear 22. The incomplete gear 17 on the transmission shaft 16 meshes with the straight rack 15 on the impact frame 14, causing the impact frame 14 to move on the slide rod 19 and stretch the spring 20. When the incomplete gear 17 and the straight rack 15 disengage, the elastic potential energy of the spring 20 is released, causing the impact frame 14 to strike the anode plate 10, shaking off the dust adsorbed on the anode plate 10.

[0035] Dust handling: The shaken dust falls into the movable box 5, which is connected to the collection chamber 8. The operator can remove the movable box 5 by grasping the handle on it, making it easy to handle the dust collected inside.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
