Field of the Invention The present invention relates to a dryer for a recycled asbestos plant, and more particularly, to a dryer for a recycled asbestos plant, which can be agitated while minimizing fusion of recycled ascon by a blade installed in a cylindrical body of the dryer .
Ascon is a term used to reduce asphalt concrete. It refers to a mixture of asphalt and sand, gravel, dust and additives, and is widely used for road pavement and parking lots. Generally, it contains about 900 ~ 950kg of aggregate (gravel, sand, dust, filter) and about 50 ~ 100㎏ of asphalt component (additive) based on 1,000kg of asconone.
As shown in Fig. 1, an ascon plant for producing such an ascon is made up of a cold bin 1 having a plurality of aggregate loading hoppers into which aggregate is charged, an aggregate dryer 1 for heating and drying the aggregate fed into the cold bin 1, (2), a sorter (3) for sorting the heat-dried aggregate into five size classes according to the particle size, an aggregate input controller (3) for selecting the aggregate to be moved to the mixer, 4), an
On the other hand, the roads packed with the ascon can be deformed or damaged due to the passage, weight and aging of the vehicle, and a large amount of waste ascon is generated during the repairing process.
Fig. 2 shows a schematic configuration diagram of the regenerated asbestos dryer in the regenerated ascon plant. In addition to the constitution of the ascon plant, the constitution for regenerating the used ascon is similar to that of the regenerated ascon reactor. An
In this constitution of the ascon plant, the regenerated asbestos dryer 1a comprises a cylindrical body, a driving means for rotating the cylindrical body, and a burner.
Japanese Patent Application Laid-Open No. 10-1012657 discloses a dryer for regenerated asbestos. The dryer for recycled asbestos according to the related art has a heat insulating cylinder having an inlet for charging the recycled ascon and an outlet for discharging the recycled ascon, the inlet being inclined higher than the outlet, and a heat insulating cylinder disposed at one side of the heat insulating cylinder close to the inlet A burner for generating a flame inside the heat insulating cylinder, a communication pipe installed inside the heat insulating cylinder for transferring the regenerated asphalt to surround the flame of the burner and to prevent the direct contact of the flame with the regenerating asphalt introduced through the inlet And a plurality of blades provided on an inner circumferential surface facing the other side of the heat insulating cylinder at a combustion passing interval and driving means for rotating the heat insulating cylinder.
FIG. 2A is a perspective view showing a structure of a blade installed inside the heat insulating cylindrical body. FIG.
Referring to FIG. 2A, the
However, in the bent plate-shaped blades, the additive of the recycled ascon is melted and adhered to scale in the rotating direction. There is a problem that the amount of the recycled ascon to be dropped falls as the scale is generated and the stirring efficiency is lowered.
In addition, when the wing is provided on the entire inner length of the heat insulating cylindrical body, the wing disposed close to the burner side has a problem that scale generation is increased.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a dryer for a recycled asbestos plant capable of preventing the scaling due to the alternation of recycled ascones.
Another object of the present invention is to provide a dryer for a recycled asbestos plant which can increase stirring efficiency.
In order to solve the above-described problems, a dryer for a reclaimed asbestos plant according to the present invention is a dryer for a recycled asbestos plant, which is installed to be inclined downward from an inlet side to an outlet side, A burner provided at an inlet side of the cylindrical body for supplying heat to the cylindrical body and a driving means for rotating the cylindrical body, wherein the blade has one end connected to the inner wall of the cylindrical body, The other end of which is protruded from the center and is bent in the direction opposite to the rotation direction; And a plurality of cross bars provided between the frames.
In this case, the wings are provided alternately in the inner middle portion and the outlet side of the cylindrical body. Screws having a predetermined length are arranged in two rows inside the inlet side of the cylindrical body, and the screw A plurality of step portions formed in the longitudinal direction of the cylindrical body are provided in the circumferential direction.
In this case, the stepped portion and the protruding formed step portion are provided so as to cross each other at the rear end side of the screw arranged at the rear end side.
According to the present invention, since the scale to which the recycled ascon is fused and adhered to the wing can be minimized, the stirring efficiency is increased and the drying efficiency of the recycled ascon can be improved.
In addition, as the generation of scale is minimized, it is possible to increase the production of recycled asphalt by allowing continuous charging or mass input.

Here, the reason for heating the aggregate is to remove moisture contained in the aggregate. When moisture is contained in the aggregate, the moisture contained in the aggregate forms a water film on the aggregate surface, thereby preventing the additive from adhering to the aggregate, which causes deterioration of the quality of the ascon. Therefore, the aggregate used in the ascon is subjected to a drying process.
