ムｌｌ内に供給している。10 is a waste material dryer installed above the aggregate dryer 1, which connects the exhaust flue 9 of the aggregate dryer 1 and introduces gas whose temperature has been lowered through heat exchange within the aggregate dryer 1 to dry the waste material. It is used to heat. The waste material dryer 10 is
It has almost the same structure as the aggregate dryer 1, and has a cylindrical drum 11 with scraping blades arranged around its inner periphery, which is tilted and rotatably supported on a machine base 12, and rotated at a predetermined speed. An input hopper 13 is provided at one end of the drum 11, and a discharge hopper 14 is provided at the other end, and waste materials are supplied into the drum 11 via a belt conveyor 15.

The waste material heated by the waste material dryer 10 is dropped into the chute 16 by a discharge blade 17 provided around the outer periphery of the end of the drum 11, and is received by the cup blade 18 provided around the outer periphery of the end of the drum 2. It is fed into the drum 2 through a through hole 19 cut out in the drum steel plate inside the blade 18.

加熱昇温されるのである。The waste material supplied to the waste material dryer 10 is transferred to the aggregate dryer l.
As the asphalt adhering to the waste materials comes into contact with the gas whose temperature has decreased due to heat exchange inside the waste materials, the asphalt content on the waste materials increases in temperature without being heated to an extreme level, softens and becomes sticky, and causes the waste materials to stick to each other, especially the fine pieces of the waste materials. After the particles and fine particles are adhesively bonded and increased in size, they are fed into the aggregate dryer l via the chute 16 connected to the discharge hopper 17 of the waste material dryer 10, and transferred and flowed down in the drum 2 together with new aggregate. During this time, the temperature is increased to a desired temperature.

再利用が可能となるものである。Therefore, the waste material fed into the aggregate dryer l is granulated to increase its heat capacity, and since it also adheres to new aggregate in the aggregate dryer l, the waste material is further granulated, its heat capacity increases, and it is exposed to high-temperature gas. Even when exposed, the asphalt component is not overheated above the deterioration temperature, the asphalt component is prevented from burning and deteriorating, and a high-quality asphalt mixture can be produced. In addition, when waste wood is heated, a harmful exhaust gas called blue smoke is generated.The cause of this is that the fine particles with a small heat capacity in the waste wood are heated too much, and the asphalt that adheres to the fine particles burns and the weight This is thought to be because the gas is so light that it gets caught up in the gas flow, is carried away with the exhaust gas, and is emitted from the chimney.However, since the temperature of the gas introduced into the waste material dryer 10 is low, the waste material scattered from the waste material dryer 10 is Since the fine particles are not heated much, the asphalt adhering to the fine particles has not been burned, making it possible to prevent blue smoke as much as possible, and furthermore, the fine particles of waste material captured by the dust collector can be reused. It is something.

となるものである。Effects of the Invention As described above, the present invention makes it possible to regenerate the asphalt in waste materials while avoiding burning and deterioration as much as possible, and also prevents the generation of blue smoke, which is different from the conventional method. Since the aggregate dryer and the waste material dryer are not connected in series, the waste material dryer is installed above the aggregate dryer, so the installation area of the equipment is small and the factory site can be used effectively. Even when a waste material dryer is added to the aggregate dryer of an existing asphalt plant, there is no WK problem, and furthermore, there is no need for a conveying device for supplying the waste material heated by the waste material dryer 10 to the aggregate dryer 1.
