Stirring-type heating bin for asphalt mixture
The invention discloses a stirring-type heating bin for an asphalt mixture. The heating bin comprises a bin body, a stirring shaft and a heater, wherein the bin body is rectangular and provided with a bin door, and a discharging hole is formed in a lower end part of the bin body; the bin body adopts a dual-layer hollow structure and is provided with an outer wall and an inner wall, and a longitudinal arc structure is arranged at the bottom of the inner wall of the bin body; the stirring shaft is horizontally and longitudinally arranged in the bin body and provided with symmetrical rectangular frame type stirring blades; a plurality of heat air inlets are formed in the inner wall of the bin body, a smoke outlet is formed in an upper part of the bin body, and the heater is mounted between the outer wall and the inner wall at the bottom of the bin body. Hot gas generated by the heater is used for heating the inner wall of the bin body and indirectly the mixture in the bin; the hot gas enters the bin body and is fully mixed with the mixture under the rotational action of the blades of the stirring shaft; the blades of the stirring shaft also achieves an effect of turning over the mixture at the bottom of the bin body, so that local overheating of the mixture at the bottom of the bin body is prevented; the heating bin prolongs the contact time of the hot gas and the mixture, increases the heat utilization rate, and shortens the heating time.
