Description

Technical Field

[0001] The utility model relates to the technical field of anti-blocking devices for dust collectors, in particular to an anti-blocking ash hopper device for a dust collector. Background Art

[0002] The ash hoppers of existing electrostatic precipitators usually set steam heating or electric heating as ash hopper heat tracing to prevent the ash hopper from being blocked due to the decrease in ash temperature and fluidity. At the same time, fluidizing air is set at the ash discharge port of the ash hopper, and the air temperature is increased to about 90 - 120 °C by electric heating and blown into the ash hopper to fluidize the ash in the ash hopper. The above devices all have the problems of high power consumption and complex systems.

[0003] In order to solve the above problems, the invention patent with the application number CN109625648A proposes an ash hopper anti-blocking and heat tracing-free system for electrostatic and bag dust removal systems, coating a polymer nano material on the ash hopper surface and installing an anti-blocking device on the fluidizing air pipeline. However, when the dust collector is used for a long time, the operation of the anti-blocking device on the outer surface of the ash hopper causes vibration of the ash hopper wall, which will loosen the connection between the fluidizing air pipeline and the ash hopper, resulting in the leakage of dust inside the ash hopper through the pipeline connection, increasing the maintenance cost of the dust collector. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that when the dust collector is used for a long time, the operation of the anti-blocking device on the outer surface of the ash hopper causes vibration of the ash hopper wall, which will loosen the connection between the fluidizing air pipeline and the ash hopper, resulting in the leakage of dust inside the ash hopper through the pipeline connection, increasing the maintenance cost of the dust collector, and proposes an anti-blocking ash hopper device for a dust collector.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an anti-blocking ash hopper device for a dust collector, including a fluidizing air device, a connecting pipe is arranged on one side of the fluidizing air device, a ash hopper body is arranged on one side of the fluidizing air device, one end of the connecting pipe is connected to one side of the ash hopper body through a flange, vibrating devices for vibrating the ash hopper body are arranged on both sides of the outer surface of the ash hopper body, a support plate for supporting and installing the fluidizing air device is arranged on one side of the ash hopper body, the fluidizing air device is located at one side of the top of the support plate, and a clamping device for strengthening the connection between the connecting pipe and one side of the ash hopper body is arranged on the outer surface of the support plate.

[0006] The effects achieved by the above components are as follows: after the dust enters the ash hopper body, the fluidizing air device is operated to allow the fluidizing air with negative ion charge to enter the ash hopper body through the connecting pipe, so that the dust inside the ash hopper body collides with the negative ions and becomes negatively charged, thereby increasing the repulsive force between the dust particles and preventing them from sticking together, thereby enhancing dust dispersion. The vibrator on the outer surface of the ash hopper is operated to vibrate the ash hopper body to avoid as much as possible the dust adhering to the inner wall of the ash hopper body and forming a blockage. The connection between the connecting pipe and the ash hopper body is reinforced by the clamping device to avoid as much as possible the loosening of the connection between the connecting pipe and the ash hopper body when the vibrator is running.

[0015] Preferably, a fastening device is provided on one side of the rectangular block. The fastening device includes a U-shaped block. The two ends of the U-shaped block are fixedly connected to one side of the rectangular block. Two round rods are slidably connected to the inner wall of the U-shaped block.
