Description

Technical Field

[0001] The present invention relates to the technical field of dust removal devices, and in particular to a vibration mechanism for efficient dust removal. Background Art

[0002] The basic principle of an electrostatic precipitator is that when the dust-containing gas passes through a high-voltage electrostatic field, the dust particles are charged, and under the action of the electric field force, the charged dust particles are deposited on the dust collecting plate. When the dust accumulates to a certain thickness, it is shaken off into the ash hopper by vibration and the dust is discharged through the ash discharge valve, so as to achieve the purpose of dust removal.

[0003] The cathode system is the main component for establishing the electric field in the electrostatic precipitator, which determines the strength of the discharge and directly affects the charging of dust in the gas and the driving effect on the electrodes. If the cathode wires in the cathode system are not cleaned in time, serious ash fouling may occur, normal corona cannot be generated, the corona current will decrease accordingly, thus affecting the charging of dust and reducing the dust removal efficiency. The cleaning of the cathode system is generally achieved by mechanical vibration.

[0004] In the traditional cathode vibration device, the vibration shaft is supported and connected to the bearing installed in the suspension bracket. The shaft end of the vibration shaft is connected to the power output shaft of the driving mechanism through a coupling to drive rotation. The vibration shaft is generally composed of two concentric shafts connected together, and its length is relatively long. After being installed on the suspension bracket and connected to the driving mechanism at one end, it is very difficult to ensure concentricity. In this way, after using for a period of time, the vibration shaft and the driving shaft often show non-concentric phenomena. In the light case, the rotation flexibility of the vibration shaft is reduced, the power output of the driving mechanism increases, and the operating cost is improved; in the heavy case, the vibration shaft will be stuck, the vibration of the cathode frame will stop, the cathode wires cannot be cleaned in time, and serious ash fouling of the cathode wires will occur, thus affecting the dust removal efficiency. Therefore, this application proposes a vibration mechanism for efficient dust removal to solve such problems. Summary of the Invention

[0016] Preferably, the rapping mechanism includes a rack, a rotating column, a gear, a rapping arm, a first transmission wheel, a second transmission wheel and a transmission belt. The rotating columns are rotatably connected to the upper and lower sides of the inner cavity of the housing.

A rack is fixedly connected to the upper part of the outer side wall of the sliding sleeve, and the rack is meshed with the gear.

Through the cooperation of the first transmission wheel, the second transmission wheel and the transmission belt, the upper vibration arm can also rotate. Since the upper and lower vibration arms are biased in opposite directions, the function of indirectly vibrating the cathode plate is realized, causing the dust on the cathode plate to fall, ensuring that the cathode plate has a strong adsorption force. When the first transmission wheel and the second transmission wheel rotate, the transmission belt will move up and down. At this time, the clamping seat will drive the scraping plate to move up and down, realizing the function of cleaning the dust on the surface of the cathode plate, further improving the dust removal efficiency of the entire device. Through the setting of the vibration mechanism and the reciprocating mechanism, etc., compared with the traditional method of directly connecting the shaft end of the vibration shaft to the power output shaft of the drive mechanism through a coupling, the service life and ash removal quality of the entire device are greatly improved.

[0035] Among them, the driving mechanism 5 includes a bracket 51, an impeller 52, a transmission shaft 53 and a first bevel gear 54.

Through the setting of the driving motor 11, the entire device can provide power output in any state, ensuring the normal operation of the entire device.

[0037] Among them, the vibrating mechanism 7 includes a rack 71, a rotating column 72, a gear 73, a vibrating arm 74, a first transmission wheel 75, a second transmission wheel 76 and a transmission belt 77. The upper and lower sides of the inner cavity of the housing 1 are rotatably connected with a rotating column 72. A gear 73 is fixedly connected to the middle of the outer side wall of the rotating column 72. A rack 71 is fixedly connected to the upper part of the outer side wall of the sliding sleeve 63.

The vibrating arms 74 on the upper and lower sides are biased in opposite directions;

[0038] When the sliding sleeve 63 reciprocates on the reciprocating threaded groove rod 61, the rack 71 will also be able to reciprocate. At this time, the rack 71 will drive the lower gear 73 to rotate the rotating column 72.

Through the cooperation of the first transmission wheel 75, the second transmission wheel 76 and the transmission belt 77, the upper vibrating arm 74 can also be rotated. Since the upper and lower vibrating arms 74 are biased in opposite directions, the function of indirectly vibrating the cathode plate 4 is realized, so that the dust on the cathode plate 4 falls off, ensuring that the cathode plate 4 has a strong adsorption force.

[0039] Among them, the scraping mechanism 8 includes a clamping seat 81 and a scraping plate 82.

[0041] In the present invention, when the ash material in the ash hopper is discharged from the outlet of the ash hopper 2, the ash material can drive the impeller 52, causing the transmission shaft 53 to drive the first bevel gear 54 to rotate. Through the meshing connection between the first bevel gear 54 and the second bevel gear 64, the second bevel gear 64 will drive the drive rod 3 to rotate. At this time, the reciprocating threaded groove rod 61 will also rotate. Cooperating with the rack 71, the sliding sleeve 63 can slide left and right on the reciprocating threaded groove rod 61, providing power output for subsequent ash removal operations, reducing the production energy of the entire device. Through the setting of the drive motor 11, the entire device can provide power output in any state, ensuring the normal operation of the entire device. When the sliding sleeve 63 reciprocates on the reciprocating threaded groove rod 61, the rack 71 will also be able to reciprocate. At this time, the rack 71 will drive the lower gear 73 to rotate the rotating column 72. Through the fixed connection between the vibration arm 74 and the rotating column 72, the lower vibration arm 74 will rotate. Through the cooperation of the first transmission wheel 75, the second transmission wheel 76 and the transmission belt 77, the upper vibration arm 74 can also rotate. By the upper and lower vibration arms 74 having opposite deflections, the function of indirectly vibrating the cathode plate 4 is realized, causing the dust on the cathode plate 4 to fall off, ensuring that the cathode plate 4 has a strong adsorption force. When the first transmission wheel 75 and the second transmission wheel 76 rotate, the transmission belt 77 will move up and down. At this time, the clamping seat 81 will drive the scraping plate 82 to move up and down, realizing the function of cleaning the dust on the surface of the cathode plate 4, further improving the dust removal efficiency of the entire device.
