The invention discloses a multi-purpose energy-saving type roller kiln. The multi-purpose energy-saving type roller kiln comprises a kiln body, a roller bar, a kiln bracket and a driving device, wherein a feed opening and a discharge opening are respectively formed in both side walls of the kiln body in the length direction, and the driving device which communicates with the feed opening and the discharge opening is horizontally arranged in an inner cavity of the kiln body; insulating bricks are installed on the top of the inner cavity of the kiln body; fire blocking grooves are oppositely formed in both side walls of the kiln body in the width direction and are located between the insulating bricks and the driving device; the fire blocking grooves communicate with the inside and the outside of the kiln body; a plurality of fire blocking grooves are alternately formed between the feed opening and the discharge opening of the kiln body, so that the inner cavity of the kiln body is divided into a preheating area, a high-temperature area, a rapid cooling area and a cooling area in sequence; the kiln bracket is installed outside the side wall of the kiln body in the width direction; both ends of the roller bar are arranged in the two opposite fire blocking grooves; and the both ends, which protrude from the kiln body, of the roller bar are respectively connected to the kiln bracketby virtue of fixed parts. The multi-purpose energy-saving type roller kiln has the advantages of implementation in variety production, small occupied area, less investment, convenience in operation and high system safety.
