[0025] Please also read Figures 1 to 6 , the anode mechanism of the electrostatic precipitator for preventing secondary dust from being vibrated provided by the present invention is now described. The anode mechanism of the electrostatic precipitator for preventing secondary dust from being vibrated comprises a mounting frame 10, a plurality of anode plates 20 and a driving assembly, wherein 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 comprises two split plates 21 and a rotating shaft 22, the rotating shaft 22 is rotatably connected to the mounting frame 10, and one end of the two split 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 split plate 21 of the anode plate 20, and is used to drive the split plate 21 to rotate around the rotating shaft 22.

[0026] Specifically, the mounting frame 10 is composed of a bottom beam and a top beam, the top beam is fixed by an existing hanging structure, and the bottom beam is fixed by an existing supporting structure.

[0027] The beneficial effect of the anode mechanism of the electrostatic precipitator for preventing secondary dust from being shaken provided by the present invention is as follows: compared with the prior art, the anode mechanism of the electrostatic precipitator for preventing secondary dust from being shaken provided by the present invention, when dust removal is not needed, the two sub-plates 21 of the anode plate 20 are merged together and kept parallel to the cathode, so that the electric field remains uniform and the dust removal effect is guaranteed; when dust removal is needed, the driving component 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 collecting surfaces of the anode plate 20 are on the leeward side, thereby effectively reducing the probability of the fallen dust being rolled up by the airflow again, thereby achieving the effect of suppressing secondary dust, and thereafter, the driving component drives the sub-plate 21 to reset again, and normal dust removal operations can be carried out.

[0028] like Figures 1 to 3 As shown, in a specific implementation of the anode mechanism of the electrostatic precipitator for preventing secondary dust from being vibrated provided in an embodiment 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 sub-plates 21, and the power input end is connected to the power output end of the driving mechanism.

[0029] Further, such as Figure 1 and Figure 2 As shown, in a specific implementation of the anode mechanism of the electrostatic precipitator for preventing secondary dust from being vibrated provided in an embodiment of the present invention, the driving assembly includes two linkage mechanisms 30, and the two linkage mechanisms 30 are respectively arranged at the upper and lower ends of the split plate 21 to make the rotation of the split plate 21 more stable and avoid deflection and twisting of the split plate 21.

[0030] Specifically, Figure 3 As shown, in a specific implementation of the anode mechanism of the electrostatic precipitator for preventing secondary dust from being vibrated provided by an embodiment 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 slides with the mounting frame 10, and has the 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; a 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 split plate 21, and the other end is arranged away from the rotating shaft 22 and is rotatably connected to the sliding frame 31. The sliding frame 31 reciprocates along the width direction of the mounting frame 10, and the split plate 21 can be driven to rotate by the connecting rod 32, so that the dust collecting surface on the split plate 21 is on the leeward side, or parallel to the cathode frame. By connecting with all the split plates 21 through the linkage mechanism 30, the rotation of all the split plates 21 can be controlled by a power output unit, which effectively reduces the equipment cost.

[0031] Further, such as Figure 5 and Figure 6As shown, in a specific implementation manner of the anode mechanism of the electrostatic precipitator for preventing secondary dust from being vibrated provided in an embodiment of the present invention, a tightening assembly is also included, a transverse slide groove is opened in the mounting frame 10, and a vertical slide groove is opened on the upper side of the transverse slide groove, and an avoidance groove is opened on the lower side, the vertical slide groove and the avoidance groove are both connected to the transverse slide groove, and the tightening assembly includes a first wedge block 41 and a second wedge block 42, the first wedge block 41 is slidably arranged in the vertical slide groove, has the freedom of vertical sliding, and the upper end is suitable for extending out of the vertical slide groove and abutting against the partition plate 21; the second wedge block 42 is slidably arranged in the transverse slide groove, has the freedom of transverse sliding, the second wedge block 42 is suitable for sliding toward the first wedge block 41 to lift the second wedge block 42, and the second wedge block 42 is connected to the sliding frame 31 through the avoidance groove.

[0032] It should be noted that the transmission of vibration requires two parts to fit closely, that is, the anode plate 20 and the mounting frame 10 need to fit closely. However, if the anode plate 20 and the mounting frame 10 fit closely, the rotation resistance of the two sub-plates 21 of the anode plate 20 will be increased. Therefore, a certain gap is set between the sub-plate 21 and the mounting frame 10 to effectively reduce the rotation resistance, and then a tightening assembly is set. When the sliding frame 31 moves and drives the sub-plate 21 to rotate outward, the second wedge block 42 is synchronously driven toward the first wedge block 41 to lift the first wedge block 41, so that the first wedge block 41 and the anode plate 20 fit closely, effectively transmitting vibration and ensuring the rapping effect.

Each sliding frame 31 corresponds to two push pieces 53, and the two push pieces 53 are symmetrically arranged on both sides of the rapping hammer 55 to make the sliding frame 31 bear the force more evenly and avoid the sliding frame 31 from getting stuck or bending.

[0041] The roller 553 is made of metal and has a large mass. The arc frame 552 is rotatably connected to the fixed frame 551 to utilize the gravity of the arc frame 552 and the roller 553 to accelerate and increase the vibration force.
