The roller cooling and dedusting device of the utility model, when in use, fixes the cooling water pipe through the adjusting device, so that the arc-shaped cooling water pipe is arranged coaxially with the roller, and fills the cooling water pipe with water, and the water filled in the cooling water pipe The flat nozzles connected to it spray out, because several flat nozzles are arranged in a rectangular array, the flat nozzles at both ends are placed horizontally, the flat nozzles on both sides are placed vertically, and the rest of the flat nozzles are vertically arranged, so that the surrounding sprayed The water mist forms a circle to form a barrier to prevent the smoke and dust generated by the roll from passing through; the flat nozzle in the middle area directly sprays the center of the roll, reducing the temperature of the roll and reducing the amount of smoke and dust.

In order to facilitate the adjustment of the cooling water pipe, the adjusting device includes a fixing plate, an adjusting plate and a nut, the cooling water pipe is fixedly installed on the fixing plate, and a first rectangular through hole is opened on the fixing plate, and the adjusting plate A second rectangular through hole is opened in the length direction, and the two second rectangular through holes are arranged in parallel and at intervals. Screws are pierced in the first rectangular through hole, and two of the two screws are respectively pierced through two of the second rectangular through holes. After the second rectangular through hole is threaded with the nut, the adjustment device can adjust the angle of the cooling water pipe and the distance between the cooling water pipe and the roll by changing the position of the screw in the second rectangular through hole and changing the distance between the two screws. Specifically, changing the position of the screw in the second rectangular through hole can change the distance between the cooling water pipe and the roll, and changing the distance between the two screws can adjust the angle of the cooling water pipe.

Preferably, the flat nozzle is an atomizing nozzle, so that the mist sprayed from the flat nozzle can be more evenly contacted with the smoke and dust, and has a better dust removal effect.

The beneficial effects of the utility model are: the roll cooling and dedusting device of the utility model, when in use, the cooling water pipe is fixed by the adjusting device, so that the arc-shaped cooling water pipe and the roll are coaxially arranged, and the cooling water pipe is filled with water. The water filled in the cooling water pipe is ejected from the flat nozzles connected to it. Since several flat nozzles are arranged in a rectangular array, the flat nozzles at both ends are placed horizontally, the flat nozzles on both sides are placed vertically, and the rest of the flat nozzles are placed vertically. It is set straight so that the sprayed water mist forms a circle to form a barrier to prevent the smoke generated by the roll from passing through; the flat nozzle in the middle area directly sprays the center of the roll, reducing the temperature of the roll and reducing the amount of smoke.
