DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor device for transferring materials, and more particularly to a conveyor device capable of heating materials during transfer.

[0002]

2. Description of the Related Art Conveyors such as screw conveyors and basket conveyors are widely used for charging materials into carbonizing apparatuses and drying apparatuses. However, carbonizing equipment and drying equipment are devices that carbonize or evaporate water by heating the material.If the temperature of the input material changes, the heating conditions of these devices may vary, resulting in poor carbonization quality and quality. The drying quality becomes uneven. In particular, the influence is great in a continuous carbonizing device and a drying device. In addition, if the input material is at a low temperature, the capacity of the heat source of the carbonizing device or the drying device must be increased.

[0003]

By providing a heating means for a material in a conveyor device used for charging a material into a carbonizing device or a drying device, the temperature of the material to be charged is made uniform and the quality of the carbonized material and the quality of the dried material are stabilized. It is an object of the present invention to reduce the size of a carbonization device and a drying device which are to be a subsequent process by preheating and drying the material.

[0004]

Various apparatuses such as a screw conveyor, a basket conveyor, and a belt conveyor have been proposed as a conveyor apparatus as a material conveying means. In a conveyor device that feeds and conveys material from one end, and conveys it out from the other end, a screw type, basket type or other conveying means is installed inside the inner casing, a predetermined space is provided outside the outer casing, and the outer casing is provided. It was attached and hot air was blown into this space. As a result, the material supplied from the charging port is heated during the transportation by the transportation means, so that the material can be adjusted to a constant temperature or a part of the moisture can be evaporated. That is, even if the temperature of the material charged into the inlet fluctuates, if the material temperature at the outlet becomes constant, the material charging temperature to the carbonization device and the drying device in the subsequent process becomes constant, and the heating condition of the device becomes stable. Act on. Further, in the case where the post-process is a carbonization apparatus, stabilization of the carbonization quality and high-temperature combustion of the carbonized gas cannot be achieved unless the water is sufficiently evaporated before the carbonization is performed. If it is possible to reduce the amount of water in the material before it is introduced into the carbonization equipment, stabilization of the carbonization quality can be achieved, and at the same time, the equipment can be downsized. Acts to hold down. In addition, if hot air is blown directly into the inner casing, a part of the material being conveyed may be burned by the hot air or generate an odorous gas, and the outer casing is provided outside the inner casing,
During that time, hot air was blown. When a partition plate for diverting or rectifying hot air is installed in the space between the inner and outer casings, the hot air blown into this space flows evenly in the inner casing by this partition plate, so that heating of the material becomes uniform. At the same time, it bends into the elongated casing and acts so that distortion is less likely to occur, and the heat transfer efficiency also increases. Hot air is blown between this inner and outer casing from one end of the elongated conveyor device,
When the hot air is discharged from the other end, the temperature of the hot air decreases during that time. Therefore, if the outer periphery of the outer casing is covered with a heat insulating material and the temperature is kept low, the decrease can be reduced. The temperature in the casing becomes more uniform when a plurality of blowing positions are dispersed at two locations and near the center.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A case where a preferred embodiment of the present invention is applied to a single screw conveyor device will be described below. However, the present invention is not limited to this, and the conveying means is a double screw or basket type. In such a case, the shape of the casing is substantially rectangular, and the design of the hot air partition plate and the like can be changed accordingly. FIG. 1 shows a conveyor device 1 according to the present invention, and FIG. A space 4 is provided on the outer periphery of an inner casing 3 in which a screw 2 is provided, an outer casing 5 is provided, and heat is kept by a heat insulating material 11, and a spiral partition plate 6 is provided in the space 4.
Was attached. The material is supplied from the lower input port 7 of the conveyor, and the material is discharged from the discharge port 8, and the carbonization device 12 in the subsequent process is used.
The material is put into, for example. On the other hand, exhaust hot air from a carbonizing device or the like was blown from the hot air blowing port 9. 20 casings
When the material was heated to 0 to 220 ° C., the water content of the material was about 65% at the inlet, but was reduced to 60% or less at the carry-out port, and the temperature of the material was stable. 450-500
When heated to C, the water content was reduced by 10 to 15% or more.

[0006]

The use of the conveyor device according to the present invention for charging the material into the carbonizing device or the drying device can make the temperature of the material uniform and reduce the amount of water. And the size of the carbonizing device and the drying device in the subsequent process can be reduced. In addition, since the exhausted hot air from the carbonizing device or the like can be used as a hot air heat source blown into the conveyor device, energy can be saved.
