Rapid cooling auxiliary device based on slag drying machine of thermal power plant

The utility model discloses a quick cooling auxiliary device based on a slag drying machine of a thermal power plant, which comprises a cooling assembly and a base, support frames are symmetrically arranged on the upper surface of the base left and right, a conveying cylinder is arranged on the upper surfaces of the two support frames, and a heat conducting plate is arranged at the bottom of the conveying cylinder. When cooling water in the water storage tank makes contact with a heat conduction plate, heat exchange can be conducted with the heat conduction plate, the heat conduction plate makes contact with ash in the ash conveying process, heat in the ash is conducted into the cooling water, the temperature of the ash is reduced, and primary cooling of the ash is completed; cooling water is pressed into the flow dividing box through the communicating pipe, the cooling water in the flow dividing box is downwards sprayed out through spraying holes of the spraying hole plate and sprayed to ash slag to wet the
