Description

Technical Field

[0001] The utility model relates to the technical field of dust collector ash hoppers of thermal power plants, in particular to a dust collector ash hopper anti-blocking and heat-tracing-free dust removal device for thermal power plants. Background Art

[0002] A dust collector is a device that separates dust from flue gas. The performance of a dust collector is expressed by the amount of gas that can be processed, the resistance loss when the gas passes through the dust collector, and the dust removal efficiency. The dust collector hopper can be said to play an important role in the dust collector. The ash hopper is equivalent to a small space in a closed room. After treatment, the dust falls into the ash hopper and then is purified. By attaching an electric heating plate to the outside of the box, the temperature inside the box can be maintained, so that the dust can avoid contact with water dew and adhere to the wall to block the dust collector hopper, thereby achieving the purpose of no heating.

[0003] When the ash hopper of the dust collector of a thermal power plant is in use, dust is easily accumulated on its inner wall. When the amount of dust accumulates to a certain extent, it will affect the normal purification and discharge of the dust in the ash hopper. Generally, a vibration motor is installed to vibrate the dust on the inner wall of the inner cavity of the ash hopper of the thermal power plant to make it fall off. However, long-term use may easily loosen the screw connection of the ash hopper of the thermal power plant due to vibration, reducing its practicality. Therefore, the present application proposes an anti-blocking and heat-free ash removal device for the ash hopper of the thermal power plant to solve the above problem. Utility Model Content

[0026] In this example, a connecting box is fixed to the right side wall of the inner cavity of the dust collector hopper body 3, and the worm 206 is rotatably connected to the left side wall of the inner cavity of the connecting box. The left end of the guide cylinder 210 is fixedly connected to a nozzle, and the end of the connecting pipe 202 away from the purging device 201 is fixed to the outside of the connecting cylinder 209. A hose is fixedly connected between the inside of the nozzle and the connecting pipe 202. By starting the motor 204, the connecting rod 205 starts to drive the worm 206 to rotate, so that the worm gear 207 drives the movable rod 208 to rotate, so that the guide cylinder 210 starts to flip, and the back side of the movable rod 208 passes through the front of the guide cylinder 210 and the connecting cylinder 209 and is fixed to the back wall of the inner cavity of the guide cylinder 210.
