Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to an electrostatic dust removal airflow distribution plate vibration cleaning device. Background Technology

[0002] An airflow distribution plate is a perforated plate or flow guide structure installed at the inlet of an electrostatic precipitator. Its core function is to evenly distribute the airflow and ensure that the dust-laden gas passes evenly through the electric field area. The rapping cleaning device can remove the dust accumulated on the distribution plate in the electrostatic precipitator. Through periodic vibration or impact, the adsorbed dust is dislodged, maintaining the electric field strength and dust removal efficiency.

[0003] For example, the announcement number CN107051745A is titled "An Electrostatic Dust Removal Airflow Distribution Plate Vibration Cleaning Device". The device includes an airflow distribution plate, a fixed block, a transmission device, a fixing screw, a connecting seat, a base, a rotating shaft, and a vibration device. There are two or more airflow distribution plates that are perpendicular to each other with the rotating shaft. The airflow distribution plate and the base are integrated into one structure. The device includes a transmission device, a rotating shaft, and a cleaning device. The rotating shaft can be driven to rotate by the slow and frequent rotation of the rotating device, which in turn drives the cleaning device to work and shake off the dust on the airflow distribution plate.

[0004] The striking structure of the above-mentioned device can only strike a fixed area, and the inability to strike evenly will reduce the dust removal effect. Therefore, we propose an electrostatic dust removal airflow distribution plate rapping dust removal device to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide an electrostatic dust removal airflow distribution plate vibration cleaning device to solve the problem mentioned in the background art that the striking structure of the above-mentioned device can only strike a fixed area and cannot strike evenly, which will reduce the dust removal effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electrostatic dust removal airflow distribution plate vibration cleaning device, comprising a sleeve, a distribution plate body and a fixing frame, wherein the distribution plate is installed inside one end of the sleeve and the fixing frame is located on both sides above the sleeve;

[0007] Also includes:

[0008] A circular ring is movably engaged within the inner middle layer of a sleeve. Four rotating rods are installed on one side of the inner wall of the sleeve, evenly distributed around the inner wall. The rotating rods are located between the distribution plate body and the circular ring. A striking arm is installed at the upper end of each rotating rod. The striking arm rotates on the upper end of the rotating rod via a pivot, and is reset by a return spring installed outside the rotating rod after rotation. A striking head is provided at the end of the striking arm closest to the distribution plate body. A lever is provided on one side of the inner wall of the circular ring, and the lever contacts the other end of the striking arm when the circular ring rotates.

[0009] Preferably, four limiting rods are evenly distributed around the inner wall of the sleeve. The four limiting rods are set on one side of the striking arm at the corresponding position, and one side of the ring is movably fitted to one side of the limiting rod.

[0010] Preferably, the two sets of fixing frames are respectively equipped with a drive shaft and a driven shaft inside. One end of the drive shaft is connected to a motor, and the motor is located outside the fixing frame at the corresponding position. The drive shaft and the driven shaft are connected to a transmission belt. A through groove is provided on the side of the sleeve near the transmission belt, and the through groove communicates with the inside of the sleeve.

[0011] Preferably, the outer surface of the ring is provided with a plurality of evenly distributed second teeth, and the outer surface of the transmission belt is provided with a plurality of evenly distributed first teeth, which pass through the through groove and engage with the second teeth for transmission connection.

[0012] Preferably, a limiting frame is provided on the side of the sleeve away from the distribution plate body, and the limiting frame is attached to one side of the ring. A pressure block is provided on the side of the limiting frame close to the ring, and the pressure block is movably attached to the inner wall surface of the ring.

[0013] Preferably, a sliding groove is provided on the inner wall of the sleeve near the limiting frame, and a slider is provided at the bottom of the limiting frame. The limiting frame is installed inside the sleeve by the engagement of the slider and the sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By installing a ring inside the sleeve and setting an impact arm between the ring and the distribution plate, and setting a lever on one side of the inner wall of the ring, when the ring is rotated, the lever contacts the impact arm on the inner wall of the sleeve in sequence. The impact arm rotates backward through the lever. After the lever is disengaged from the impact arm, the impact arm is reset by the action of the return spring, so that the striking head at the front end of the impact arm hits the distribution plate, causing the dust on the surface of the distribution plate to fall off.

[0016] (2) By installing a fixed frame above the sleeve, the transmission belt is installed between the two fixed frames and driven by the motor to rotate. The transmission belt has teeth on the outside and meshes with the teeth on the outer wall of the ring, so that the transmission belt drives the ring to rotate slowly inside the sleeve, thereby driving the lever to periodically touch several striking arms inside the sleeve, so that the striking head strikes the surface of the distribution plate evenly, thereby improving the dust removal efficiency.
