[0002] Fly ash is a fine ash collected from the flue gas after coal combustion. It is a major solid waste discharged from coal-fired power plants. With the development of the power industry, the amount of fly ash emitted by coal-fired power plants has been increasing year by year, making it one of the industrial waste residues with the largest discharge volume in my country.

However, during the conveying process of fly ash, the feed inlet and outlet of the above-mentioned feeding device are usually prone to overflowing dust, which is not convenient for timely dust treatment and pollutes the working environment. Therefore, this utility model is proposed. Utility Model Content

[0022] In this embodiment, the inlet end of the L-shaped bend 301 is connected to an external water pipe, and a rotating gear 304 is fixedly fitted on the lower part of the vertical pipe 302. An L-shaped rack 305 is meshed on one side of the rotating gear 304. The L-shaped rack 305 is horizontally and vertically slidably mounted on the inverted L-shaped plate 3. An electric telescopic rod 307 is connected to the back of the L-shaped rack 305. A vertical plate 306 is connected to the back end of the electric telescopic rod 307. The vertical plate 306 is fixed on the inverted L-shaped plate 3. A sensing block 308 is provided on the front end of the L-shaped rack 305. A first position block 309 and a second position block 310 are sequentially provided on one side of the inverted L-shaped plate 3. It should be noted that the external water pipe, the electric telescopic rod 307, the sensing block 308, the first position block 309, and the second position block 310 are existing technologies.

[0023] In this embodiment, the dust extraction assembly further includes a first connecting pipe 206 connected to the first absorption pipe 201, a second absorption pipe 203 disposed on the front of the discharge pipe 102, a second connecting pipe 205 connected to the second absorption pipe 203, the second connecting pipe 205 and the first connecting pipe 206 being connected to the collection box 2, a switch door disposed on the front of the collection box 2, a negative pressure fan 207 disposed on the top of the collection box 2, a second folding plate 204 fixed to the bottom of the second absorption pipe 203, and the second folding plate 204 being fixed to the support frame 103.
