Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Referring to Figures 1 to 3, it can be known that a natural gas annealing furnace roller includes a water pipe 1, the water pipe 1 is spiral, the left end of the water pipe 1 is integrally connected to the water outlet pipe 2, and the right end of the water pipe 1 The water inlet pipe 3 is integrally connected, the outlet pipe 2 and the water inlet pipe 3 are fixedly sleeved with baffles 4, and the outer cylinder 5 is fixedly connected between the baffles 4, and the water outlet pipe 1 is located inside the outer cylinder 5. A water delivery pipe 6 is installed on the outside of the water inlet pipe 1, and the water delivery pipe 6 is arranged vertically to the water inlet pipe 3. Through holes 7 are provided on both sides of the water delivery pipe 6, and a ring 8 and a disc 9 are respectively installed inside the water delivery pipe 6. , the circular ring 8 and the disc 9 are fixedly connected through the connecting rod 10, the end of the water inlet pipe 3 is integrally connected to the circular ring 8 through the through hole 7, and the disc 9 is integrally connected to the shaft rod 11 of the motor, so The shaft 11 passes through the through hole 7 .

The inner side wall of the outer cylinder 5 is connected with cooling fins 12 at intervals to facilitate heat dissipation of the outer cylinder 5; the water delivery pipe 6 is a rectangular pipe, which is convenient for installing the ring 8 and the disc 9; the shaft rod 11 and the water inlet pipe 3 are connected with the A waterproof ring is installed between the side walls of the through hole 7 to prevent water leakage.

The principle and advantages of the present invention: when in use, the water supply pipe 6 is first fixed on the shell or bracket of the machine to keep it stable, and the water circulation pipe is connected to the water outlet pipe 2 to realize the reuse of cooling water or the optimal utilization of warm water. When the water supply pipe 6 is filled with cooling water, the shaft 11 of the motor rotates, and the shaft 11 drives the disc 9 to rotate. Since the ring 8 and the disc 9 are fixedly connected by the connecting rod 10, the water inlet pipe 3 connected to the ring 8 It also rotates accordingly, so that the outer cylinder 5 outside the water inlet pipe 3 also rotates, and realizes its function as a furnace roller. The cooling water enters the water inlet pipe 3 from the ring 8, and enters the water pipe 1 from the water inlet pipe 3. The rapid transfer of heat through the radiating fins 12 increases the temperature in the outer cylinder 5 , and part of the heat is taken away during the output of the water outlet pipe 1 from the outlet pipe 2 , reducing the temperature of the outer cylinder 5 .

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
