[0043] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0044] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present application and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0045] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they specify the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0046] Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions, and numerical values set forth in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for the sake of convenience of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not require further discussion in subsequent drawings.

[0047] In the description of the present application, it should be understood that orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom", etc., generally indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present application and simplifying the description. Without contrary explanation, these orientation terms do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the protection scope of the present application; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0048] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper" etc. can be used here to describe the spatial positional relationship of a device or feature shown in the figure with other devices or features.

The device can also be positioned in other different ways, and corresponding interpretations should be made for the spatial relative descriptions used here.

[0049] In addition, it should be noted that the use of terms such as "first", "second" etc. to define components is only for the convenience of differentiating the corresponding components. Without additional statements, the above terms have no special meanings, and thus should not be construed as limiting the protection scope of this application.

[0050] Please refer to Figures 1 to 6 simultaneously. Now, an anode mechanism for preventing secondary dust emission during rapping of an electrostatic precipitator provided by the present invention will be described. The anode mechanism for preventing secondary dust emission during rapping of the electrostatic precipitator includes a mounting frame 10, a plurality of anode plates 20, and a driving assembly. The mounting frame 10 is fixedly arranged; the plurality of anode plates 20 are arranged side by side along the width direction of the mounting frame 10. The anode plate 20 includes two sub - plates 21 and a rotating shaft 22. The rotating shaft 22 is rotatably connected to the mounting frame 10. One end of the two sub - plates 21 along the width direction of the mounting frame 10 is rotatably connected to the rotating shaft 22; the power output end of the driving assembly is connected to the sub - plate 21 of the anode plate 20 to drive the sub - plate 21 to rotate around the rotating shaft 22.

[0051] Specifically, the mounting frame 10 is composed of a bottom beam and a top beam. The top beam is fixed through an existing hanging structure, and the bottom beam is fixed through an existing supporting structure.

[0052] The beneficial effects of the anode mechanism for preventing secondary dust emission during rapping of the electrostatic precipitator provided by the present invention are as follows: Compared with the prior art, in the anode mechanism for preventing secondary dust emission during rapping of the electrostatic precipitator provided by the present invention, when dust removal is not required, the two sub - plates 21 of the anode plate 20 are combined together and kept parallel to the cathode, making the electric field uniform and ensuring the dust removal effect; when dust removal is required, the driving assembly drives the two sub - plates 21 of the anode plate 20 to rotate and separate around the rotating shaft 22, so that the two dust collection surfaces of the anode plate 20 are on the leeward side, thereby effectively reducing the probability that the falling dust is rolled up again by the air flow, achieving the effect of suppressing secondary dust emission. After that, the driving assembly drives the sub - plate 21 to reset again, and normal dust removal operations can be carried out.

[0053] As Figures 1 to 3 shown, in a specific implementation manner of the anode mechanism for preventing secondary dust emission during rapping in the electrostatic precipitator provided by the embodiments of the present invention, the driving assembly includes a linkage mechanism 30 and a driving mechanism. The power output end of the linkage mechanism 30 is connected to all the dividing plates 21, and the power input end is connected to the power output end of the driving mechanism.

[0054] Furthermore, as Figure 1 and Figure 2 shown, in a specific implementation manner of the anode mechanism for preventing secondary dust emission during rapping in the electrostatic precipitator provided by the embodiments of the present invention, the driving assembly includes two linkage mechanisms 30. The two linkage mechanisms 30 are respectively arranged at the upper and lower ends of the dividing plate 21 to make the rotation of the dividing plate 21 more stable and avoid deflection and torsion of the dividing plate 21.

[0055] Specifically, as Figure 3 shown, in a specific implementation manner of the anode mechanism for preventing secondary dust emission during rapping in the electrostatic precipitator provided by the embodiments of the present invention, the linkage mechanism 30 includes a sliding frame 31 and a plurality of connecting rods 32. The sliding frame 31 extends along the width direction of the mounting frame 10 and is slidably engaged with the mounting frame 10, having a degree of freedom to slide along the width direction of the mounting frame 10. One end of the sliding frame 31 is connected to the power output end of the driving mechanism; the plurality of connecting rods 32 are symmetrically arranged on both sides of the sliding frame 31. One end of the connecting rod 32 is rotatably connected to the dividing plate 21, and the other end is arranged away from the rotating shaft 22 and is rotatably connected to the sliding frame 31. When the sliding frame 31 reciprocates along the width direction of the mounting frame 10, the dividing plate 21 can be driven to rotate through the connecting rod 32, so that the dust collection surface on the dividing plate 21 is on the leeward side or parallel to the cathode frame. By connecting the linkage mechanism 30 to all the dividing plates 21, all the dividing plates 21 can be controlled to rotate by one power output unit, effectively reducing the equipment cost.

[0056] Furthermore, as Figure 5 and Figure 6 shown, in a specific implementation manner of the anode mechanism for preventing secondary dust emission during rapping in the electrostatic precipitator provided by the embodiments of the present invention, it further includes a pressing component. A transverse chute is opened in the mounting frame 10, and a vertical chute is opened above the transverse chute, and an avoidance groove is opened below. Both the vertical chute and the avoidance groove are communicated with the transverse chute. The pressing component includes a first wedge block 41 and a second wedge block 42. The first wedge block 41 is slidably arranged in the vertical chute, having a degree of freedom to slide vertically, and the upper end is adapted to extend out of the vertical chute and abut against the dividing plate 21; the second wedge block 42 is slidably arranged in the transverse chute, having a degree of freedom to slide horizontally. The second wedge block 42 is adapted to slide towards the first wedge block 41 to jack up the first wedge block 41, and the second wedge block 42 passes through the avoidance groove and is connected to the sliding frame 31.

[0057] It should be noted that the transmission of vibration requires two components to be closely attached, that is, the anode plate 20 needs to be closely attached to the mounting frame 10. However, if the anode plate 20 is closely attached to the mounting frame 10, the rotational resistance of the two sub - plates 21 of the anode plate 20 will increase. Therefore, a certain gap is provided between the sub - plate 21 and the mounting frame 10 to effectively reduce the rotational resistance. Then, a tightening component is set. During the movement of the sliding frame 31, which drives the sub - plate 21 to rotate outward, the second wedge block 42 is synchronously driven towards the first wedge block 41, pushing up the first wedge block 41 to make the first wedge block 41 closely attached to the anode plate 20, effectively transmitting vibration and ensuring the rapping effect.

[0058] Based on the same inventive concept, an embodiment of the present invention provides an electrostatic precipitator, which includes a plurality of the above - mentioned anode mechanisms and rapping assemblies for preventing secondary dust raising during rapping of the electrostatic precipitator. The rapping assembly includes a driving mechanism.

[0059] It should be noted that other components of the electrostatic precipitator all adopt existing components.

[0060] The beneficial effect of the electrostatic precipitator provided by the present invention for preventing secondary dust raising during rapping is that: compared with the prior art, the electrostatic precipitator provided by the present invention adopts the above - mentioned anode mechanism. Therefore, it can effectively inhibit secondary dust raising generated during rapping and maintain a uniform electric field when rapping is not required, ensuring the dust removal effect.

[0061] Specifically, further, as Figures 1 to 3 shown, in a specific embodiment of the electrostatic precipitator provided by the embodiment of the present invention, the driving mechanism includes a driving shaft 51, a motor assembly 52, a plurality of push members 53 and a plurality of return springs 54; the driving shaft 51 is rotatably arranged on one side in the width direction of the mounting frame 10; the power output end of the motor assembly 52 is connected to the driving shaft 51 to drive the driving shaft 51 to rotate; the plurality of push members 53 are arranged at intervals along the axial direction of the driving shaft 51. One end of the push member 53 is connected to the driving shaft 51, and the other end is adapted to rotate with the driving shaft 51 to push the sliding frame 31; the plurality of return springs 54 correspond to the sliding frame 31 one by one. One end of the return spring 54 is connected to the sliding frame 31, and the other end is connected to the mounting frame 10.

[0062] Further, as Figure 3 shown, in a specific embodiment of the electrostatic precipitator provided by the embodiment of the present invention, a push wheel 531 is rotatably arranged at the end of the push member 53, and the push wheel 531 is adapted to contact the sliding frame 31.

[0063] As Figure 1 and Figure 3 shown, in a specific embodiment of the electrostatic precipitator provided by the embodiment of the present invention, the rapping assembly further includes a plurality of rapping hammers 55. The plurality of rapping hammers 55 correspond to the mounting frame 10 one by one and are connected to the driving shaft 51.

[0064] Specifically, as Figure 3 shown, in a specific implementation manner of the electrostatic precipitator provided in the embodiment of the present invention, the rapping hammer 55 includes a fixed frame 551, an arc-shaped frame 552, and a roller 553. The fixed frame 551 is fixedly connected to the drive shaft 51; one end of the arc-shaped frame 552 is rotatably connected to the fixed frame 551; the roller 553 is rotatably engaged with the other end of the arc-shaped frame 552, and the roller 553 is adapted to hammer the mounting frame 10.

[0065] Specifically, the motor assembly 52 is fixedly arranged on the outer side of the electrostatic precipitator, the drive shaft 51 is rotatably arranged inside the electrostatic precipitator, the pushing member 53 is detachably mounted on the drive shaft 51, and two pushing members 53 correspond to each sliding frame 31. The two pushing members 53 are symmetrically arranged on both sides of the rapping hammer 55, so that the sliding frame 31 is stressed more evenly, avoiding jamming and bending of the sliding frame 31.

[0066] The roller 553 is made of metal and has a relatively large mass. The arc-shaped frame 552 is rotatably connected to the fixed frame 551 to utilize the gravity of the arc-shaped frame 552 and the roller 553 for acceleration and increase the rapping force.

[0067] Furthermore, a certain phase angle can be set between adjacent rapping hammers 55 for staggered rapping to further suppress secondary dust emission.

[0068] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
