Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention 1;
Fig. 2 is the structural representation of the embodiment of the invention 2.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described further.
Embodiment 1
With reference to Fig. 1; Present embodiment comprises first charging and distribution device 1-1, second charging and distribution device 1-2, entrance lock 2, exhaust apparatus 3, heating furnace body 4 and material shop shipping unit; Said first charging and distribution device 1-1, second charging and distribution device 1-2 are installed on the input of material shop shipping unit respectively; Said entrance lock 2 is installed on the top that material is spread shipping unit respectively with exhaust apparatus 3; The first half of said material shop shipping unit is passed the burner hearth of heating furnace body 4; Said material shop shipping unit constitutes by being the internal layer cycloconveyor belt 5-1 and the outer annular conveyer belt 5-2 that surround the shape arrangement, and said internal layer cycloconveyor belt 5-1 is a steel band, and said outer annular conveyer belt 5-2 is a steel mesh; The two ends of said internal layer cycloconveyor belt 5-1 dispose the first transmission device 7-1 and the first tensioning apparatus 8-1 respectively; The two ends of said outer annular conveyer belt 5-2 dispose the second transmission device 7-2 and the second tensioning apparatus 8-2 respectively, and the output of said internal layer cycloconveyor belt 5-1 is provided with the first drawing mechanism 6-1, and the output of said outer annular conveyer belt 5-2 is provided with the second drawing mechanism (not shown).
The below of said internal layer cycloconveyor belt 5-1 and outer annular conveyer belt 5-2 is equipped with carrying roller.
Said first charging and distribution device 1-1 adopt tilting oscillating feeder; Its cloth partly places the top of steel band; Its blanking limit becomes certain angle of inclination (present embodiment medium dip angle is 27 °) with steel band, be with so that material is evenly distributed on just, certainly; Also can adopt other charging and distribution device, like tilting speed-governing belt etc.The said first drawing mechanism 6-1 adopts the belt discharging machine, places the below of steel band output, to pick out material, also can adopt other drawing mechanism certainly, as vibrating discharging machine etc.Said second charging and distribution device adopt the oscillating feeder of vertically installing, and certainly, also can adopt other charging and distribution device, and like speed-governing belt or star-shaped feeding machine etc., and second drawing mechanism can directly adopt the slide carriage that connects material.
