Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

Embodiment 1, as shown in fig. 1, the structure of this embodiment is: a driving roller driving device for a kiln comprises a driving roller 1, wherein one end of the driving roller 1 extends out of a kiln 2, one end of the driving roller 1 extends out of the kiln 2 and extends into a cooling box 4 in a shell 3, the driving roller 1 is in transmission connection with a transmission shaft 5 in the cooling box 4 through a belt, a chain and the like, in the embodiment, gear transmission is adopted, therefore, a circle of driven gears 9 concentric with the driving roller 1 are arranged on the outer wall of the driving roller 1, the driven gears 9 are meshed with transmission gears 10 on the transmission shaft 5, one end of the transmission shaft 5 extends out of the shell 3 and is in transmission connection with a motor 6, bearings are arranged at the connection part of the driving roller 1 and the shell 3 and the connection part of the transmission shaft 5 and the shell 3, shaft seals are arranged at the bearings so as to ensure that cooling liquid in the cooling box 4 cannot leak out, and the motor 6 is arranged on a base outside the shell 3; and a water inlet pipe 7 and a water outlet pipe 8 are arranged on the cooling box 4 at intervals, and the water inlet pipe 7 and the water outlet pipe 8 are connected with a cooling liquid source.

When the kiln 2 works, the motor 6 drives the transmission shafts 5 to rotate through chains and the like, every three transmission shafts can be used as a group, adjacent transmission shafts are connected through the chains, and one transmission shaft is in transmission connection with an output shaft of the motor 6; the transmission shaft 5 drives the transmission roller 1 to rotate, and the driven gear 9 and the transmission gear 10 are both made of 20 chromium, manganese and titanium and are subjected to nitriding treatment.

The water rapidly removes heat from the drive shaft 5, so that the temperature of the drive shaft 5 and the motor 6 is maintained at a low temperature.

Embodiment 2, as shown in fig. 1, the other structure of this embodiment is the same as that of embodiment 1, but in this embodiment, a gap is provided between the upper and lower end surfaces of the cooling box 4 and the inner wall of the casing 3, the casing 3 is arranged along the length direction of the kiln 2, the casing 3 is a tubular structure with two open ends, the two ends of the casing 3 are respectively provided with a fan 11, and the directions of the airflows generated by the fans 11 on the two sides are the same, so that the blower 11 on one side blows the airflow into the casing 3, and the blower 11 on the other side takes away the air in the casing 3, thereby improving the airflow in the casing 3; and filter screens 12 are arranged at the two ends of the shell 3 and outside the fan 11.
