Abstract
The utility model relates to the technical field of melamine resin production, and discloses a rapid cooling reaction kettle for melamine resin production. The multiple cooling effects of cooling the reaction kettle are achieved through cooperation of the first heat exchange coil pipe, the second heat exchange coil pipe, the first water supply pipe, the second water supply pipe and other parts, and it is guaranteed that the interior of the reaction kettle is rapidly cooled. By arranging the cooling water tank and arranging the refrigeration equipment at the cooling water tank, water in the cooling water tank can be continuously cooled, and the process occurs in the reaction stage of the reaction kettle, so that the cooling water tank of the reaction kettle can continuously prestore low-temperature cooling water in the reaction stage; and then water in the cooling water tank is introduced into the first heat exchange coil pipe for heat exchange through a second water pump and a second water supply pipe, and the water in the cooling water tank is low-temperature water, so that heat exchange can be quickly completed on the outer side wall of the reaction kettle. The heat exchange valve has multiple heat exchange modes with different efficiencies, and the multiple heat exchange modes can be conveniently switched and adjusted only through the valve body.
