[0047] Please refer to Figures 1 to 4 , and now the transverse plate rapping device provided by the present utility model will be described. The transverse plate rapping device includes a rapping motor 10, a rapping shaft 20, a plurality of swing hammers 30 and a plurality of rapping anvils 40. The rapping shaft 20 is fixedly connected to the output shaft of the rapping motor 10, and the axial direction of the rapping shaft 20 is parallel to the axial direction of the output shaft of the rapping motor 10; a plurality of swing hammers 30 are arranged at intervals along the axial direction of the rapping shaft 20 and are hinged to the rapping shaft 20; a plurality of rapping anvils 40 correspond to the plurality of swing hammers 30 one by one, and the plurality of rapping anvils 40 are used for corresponding connection with the transverse plates on the electrostatic precipitator one by one;

[0048] The rapping motor 10 is used to drive the arm-wound hammer 30 to strike the rapping anvil 40 .

[0049] It should be noted that there are two specific ways for the rapping motor 10 to drive the arm hammer 30 to strike the rapping anvil 40: (1) the rapping motor 10 drives the arm hammer 30 to rotate to the highest point and then stops, and the arm hammer 30 falls and strikes the rapping anvil 40 due to its own gravity, and then the rapping motor 10 reverses to drive the arm hammer 30 back to its original position; (2) the rapping motor 10 drives the arm hammer 30 to rotate until it is thrown onto the rapping anvil 40, and then the rapping motor 10 reverses to drive the arm hammer 30 back to its original position.

[0050] The transverse plate rapping device provided in the present embodiment is, compared with the prior art, arranged around the electrostatic precipitator, and a plurality of rapping anvils 40 are fixed to the transverse plate in the electrostatic precipitator and are located outside the electrostatic precipitator. When the electrostatic precipitator is working, the rapping motor 10 is turned on once at a certain interval. After the rapping motor 10 is turned on, it drives the rapping shaft 20 to rotate by a preset angle. When the rapping shaft 20 rotates, it drives the arm-wrap hammer 30 to rotate, so that the arm-wrap hammer 30 strikes the rapping anvil 40. When the rapping anvil 40 is struck, the vibration is transmitted to the transverse plate, so that the dust on the transverse plate falls off. The transverse plate rapping device of the utility model drives a plurality of arm-wrap hammers 30 to strike the rapping anvil 40 at the same time by the rapping motor 10, so as to realize the cleaning operation of the transverse plate fixedly connected to the rapping anvil 40. The striking force of the structure is large, which is conducive to knocking off the dust with large viscosity on the transverse plate, thereby improving the cleaning effect.

[0051] In some embodiments, a specific connection method between the arm hammer 30 and the rapping shaft 20 can be as follows: Figures 1 to 2 See the structure shown. Figures 1 to 2 A mounting base 50 is also connected between each arm-wrap hammer head 30 and the rapping shaft 20. The mounting base 50 includes a U-shaped rod 51, a fixing plate 52 and a locking plate 53. The U-shaped rod 51 is wrapped around the outer periphery of the rapping shaft 20; the fixing plate 52 is plugged into and matched with both ends of the U-shaped rod 51, and a rotating shaft 55 is hinged on one side of the fixing plate 52. The axial direction of the rotating shaft 55 is parallel to the axial direction of the rapping shaft 20 and is fixedly connected to the arm-wrap hammer head 30; the locking plate 53 is fixedly connected to both ends of the U-shaped rod 51, and the locking plate 53 abuts against the side of the fixing plate 52 away from the rotating shaft 55. The U-shaped rod 51 and the fixing plate 52 are connected to enclose the outer periphery of the rapping shaft 20, and then the locking plate 53 is fixed to the U-shaped rod 51, so that the fixing plate 52 abuts against the rapping shaft 20, fixing the axial position of the U-shaped rod 51 and the fixing plate 52 on the rapping shaft 20. At this time, the axial position of the arm hammer 30 on the rapping shaft 20 is also fixed, so that it can be aligned with the position of the rapping anvil 40.

[0052] Optionally, the locking plate 53 can be welded or clamped to the U-shaped rod 51; as a variant embodiment, the locking plate 53 can also be replaced by a nut, and by providing internal threads at both ends of the U-shaped rod 51, the nut is tightened onto the internal threads to achieve the fixed plate 52 abutted against the outer periphery of the vibration shaft 20.

[0053] In some embodiments, an improved implementation of the above-mentioned fixed plate 52 can adopt the structure as Figures 1 to 2 shown. Refer to Figures 1 to 2 , two spaced-apart limiting plates 54 are provided on one side of the fixed plate 52, the rotating shaft 55 is hinged between the two limiting plates 54, and the portion of the swing arm hammer head 30 connected to the rotating shaft 55 is located between the two limiting plates 54. The swing arm hammer head 30 is located between the two limiting plates 54, and can avoid displacement in the axial direction of the vibration shaft 20 during the rotation with the rotating shaft 55, ensuring the accuracy of striking the vibration anvil 40.

[0054] In some embodiments, an improved implementation of the above-mentioned fixed plate 52 can adopt the structure as Figure 2 shown. Refer to Figure 2 , a groove 56 is provided on the side surface of the fixed plate 52 facing the vibration shaft 20, and the inner wall of the groove 56 fits against the outer peripheral surface of the vibration shaft 20. Since the plate surface of the fixed plate 52 is a plane and the outer peripheral surface of the vibration shaft 20 is an arc surface, by providing the groove 56 adapted to the outer peripheral surface of the vibration shaft 20, the contact area between the fixed plate 52 and the vibration shaft 20 can be increased, so that when the U-shaped rod 51 and the fixed plate 52 cooperate to clamp and fix the shaft, the installation strength of the mounting seat 50 can be improved.

[0055] In some embodiments, a variant connection mode between the above-mentioned vibration shaft 20 and the swing arm hammer head 30 can adopt the structure as Figure 4 shown. Refer to Figure 4 , the swing arm hammer head 30 has a hinge hole for the vibration shaft 20 to pass through, a limiting groove 21 is provided on the outer periphery of the vibration shaft 20, and the swing arm hammer head 30 is located in the limiting groove 21. In this embodiment, the swing arm hammer head 30 is directly sleeved on the outer periphery of the vibration shaft 20, and by providing the limiting groove 21, the swing arm hammer head 30 can be prevented from reciprocating in the axial direction of the vibration shaft 20, ensuring the accuracy when striking the vibration anvil 40.

[0056] In some embodiments, an improved implementation of the above-mentioned swing arm hammer head 30 can adopt the structure as Figure 2 and Figure 4 shown. Refer to Figure 2 and Figure 4The arm-wound hammer 30 has a spherical hammering part 31, and the hammering part 31 is used to strike the rapping anvil 40. The contact surface between the rapping anvil 40 and the arm-wound hammer 30 is a plane. By setting the spherical hammering part 31, the hammering part 31 and the rapping anvil 40 are in point contact, and the striking force is concentrated on the above-mentioned contact point, the striking force is greater, and the dust removal effect is better.

[0057] In some embodiments, a specific connection method between the rapping motor 10 and the rapping shaft 20 can be as follows: Figure 1 See the structure shown. Figure 1 A diaphragm coupling 60 is connected between the output shaft of the rapping motor 10 and the rapping shaft 20. The diaphragm coupling 60 can compensate for the axial, radial, and angular offsets between the output shaft of the rapping motor 10 and the rapping shaft 20, thereby reducing vibration noise and stabilizing the rotation process.

[0058] In some embodiments, an improved implementation of the above-mentioned transverse plate rapping device can be adopted as follows Figure 1 and Figure 3 See the structure shown. Figure 1 and Figure 3 The transverse pole plate rapping device also includes a base 70, a bottom plate 72 and a fastener 73. A slide groove 71 is provided on the top of the base 70, and the extension direction of the slide groove 71 is parallel to the axial direction of the rapping shaft 20; the bottom plate 72 is slidably connected to the slide groove 71; the fastener 73 is connected between the bottom plate 72 and the base 70; wherein the rapping motor 10 is fixedly connected to the bottom plate 72.

[0059] The rapping motor 10 is fixed on the base plate 72. When the fastener 73 is removed, the axial position of the rapping motor 10 on the rapping shaft 20 can be switched by sliding the base plate 72, so that the multiple arm hammers 30 on the rapping shaft 20 correspond to the multiple rapping anvils 40. After adjustment, they are fixed by the fastener 73. This structure is convenient for debugging during installation.

[0060] In some embodiments, an improved implementation of the above-mentioned lateral vibration motor 10 can be adopted as follows Figure 1 See the structure shown. Figure 1 A shock absorbing assembly 80 is also provided between the arm-wrap hammer 30 closest to the rapping motor 10 and the rapping motor 10, and the shock absorbing assembly 80 has a guide sleeve 81 that rotates with the rapping shaft 20. Since there are multiple transverse plates distributed on the electrostatic precipitator, there are also multiple corresponding arm-wrap hammers 30, so the length of the rapping shaft 20 that needs to be set is relatively long, and the rapping shaft 20 is easy to shake when it rotates if the suspended length is relatively long. By providing the shock absorbing assembly 80, the rapping shaft 20 can be supported by the guide sleeve 81 when the rapping shaft 20 rotates, thereby improving the stability of the rapping shaft 20 when rotating and achieving the effect of shock absorption.

[0061] In some instances, a specific implementation of the above shock-absorbing assembly 80 may adopt the structure as shown in Figure 1 . Refer to Figure 1 . The shock-absorbing assembly 80 further includes a housing 82 and a bearing 83. The housing 82 has a through-hole for the vibration shaft 20 to pass through, and the bearing 83 is fitted between the guide sleeve 81 and the vibration shaft 20. Among them, the guide sleeve 81 is fixed inside the housing 82 and is coaxial with the through-hole. The vibration shaft 20 passes through the housing 82 and is connected to the output shaft of the vibration motor 10. The guide sleeve 81 installed inside the housing 82 supports the vibration shaft 20, and the bearing 83 can reduce the frictional resistance between the guide sleeve 81 and the vibration shaft 20. The housing 82 can protect the guide sleeve 81 and the bearing 83.

[0062] It should be noted that in specific implementation, the housing 82 can be fixedly installed together with the above base 70.

[0063] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
