[0002] The stainless steel pipe annealing furnace is the key equipment in the pipe processing field, and its core function is to eliminate the internal stress of the pipe and improve the mechanical properties by accurately controlling the heating, heat preservation and cooling process. With the diversification of industrial application scenarios, the specifications of stainless steel pipes show significant differences, including the span of outer diameter, wall thickness and length gradually increasing. When dealing with multi-specification steel pipes, the traditional annealing furnace generally faces problems such as poor conveying stability, insufficient temperature uniformity and high energy consumption, and it is urgent to realize an efficient, environmentally friendly and adaptable solution through technological innovation.

[0003] Specifically, when steel pipes of different outer diameters are conveyed through fixed-interval rollers or chains, since the interval of the rollers or chains cannot be adjusted according to the actual size of the steel pipes, many problems may easily occur, such as pipe deviation. When the outer diameter of the steel pipe is smaller than the interval of the rollers or chains, the steel pipe may sway left and right during the conveying process due to lack of sufficient support, resulting in the occurrence of deviation. This not only affects the conveying stability of the steel pipe, but also may damage the surface of the pipe due to friction with the furnace wall or other components, or may cause jamming. On the contrary, if the outer diameter of the steel pipe is larger than the interval of the rollers or chains, the steel pipe may not pass smoothly during the conveying process due to excessive resistance. In this case, not only will the conveying efficiency be greatly reduced, but the pipe may also be severely mechanically damaged due to forced conveying.

[0022] Embodiment one

[0023] Referring to Figures 1-4 The heat storage type environment-friendly stainless steel pipe annealing furnace comprises an annealing furnace body 1, a heat storage bin 2 and a support frame 3. The top of the support frame 3 is fixedly provided with a placing rack 4. Butt joint grooves 5 are formed in the outer walls of the placing rack 4. The butt joint grooves 5 are internally provided with movable moving plates 7. The number of the moving plates 7 is two. Two conveying blocks 12 in the same axis are arranged above one moving plate 7. Four rotatable supporting blocks 13 are arranged on the top surface of the other moving plate 7. A rotatable connecting rod 15 is arranged at the middle position of the bottom surface of the placing rack 4. An abutting rod 16 is hingedly connected to the bottom of the moving plate 7 at the edge position of the bottom surface of the connecting rod 15.

[0024] Further, two mounting plates 14 are fixedly arranged on the top surface of one side of the moving plate 7. The two mounting plates 14 are symmetrically arranged. The supporting blocks 13 are rotatably arranged on the side walls of the mounting plates 14. Two supporting blocks 13 are arranged on the side wall of one mounting plate 14. The two supporting blocks 13 are arranged in the same axis.

[0025] Still further, a drive motor 9 is fixedly arranged on the top of one side of the moving plate 7. A first gear 10 is drivingly connected to one side of the drive motor 9. A rotatable second gear 11 is arranged above the first gear 10. The second gear 11 and the first gear 10 are both connected with the conveying blocks 12. The first gear 10 and the second gear 11 are in meshing engagement.

[0026] The driving motor 9 is connected with the first gear 10, the first gear 10 and the second gear 11 are connected with the conveying block 12, and the first gear 10 and the second gear 11 are engaged with each other, so that the driving motor 9 can drive the two conveying blocks 12 to rotate in opposite directions after driving the first gear 10 to rotate, thereby driving the steel pipe to move.

[0027] It should be noted that the two conveying blocks 12 and the supporting blocks 13 are not on the same axis, and the overall shape of the conveying block 12 and the supporting block 13 is conical.

[0028] By setting the conveying block 12 and the supporting block 13 not on the same axis, the staggered conveying block 12 and the supporting block 13 can stably clamp the steel pipe, and by setting the overall shape of the conveying block 12 and the supporting block 13 to be conical, the user can adjust the distance between the conveying block 12 and the supporting block 13 to adapt the device to different sizes of steel pipes.

[0029] In addition, the bottom edge of the placing rack 4 is fixedly provided with an electric push rod 17, one side of the electric push rod 17 is connected with a connecting block 18, and the connecting block 18 is fixedly connected with the moving plate 7 on one side.

[0030] In specific implementation, when the device needs to convey the stainless steel pipe into the annealing furnace body 1, the user can directly place the steel pipe above the placing rack 4, and then start the electric push rod 17. After the electric push rod 17 is started, it drives one moving plate 7 to move through the connecting block 18. Two abutting rods 16 and a connecting rod 15 are arranged between the two moving plates 7, so that when one moving plate 7 is driven, the other moving plate 7 will also move synchronously. Therefore, after the electric push rod 17 is started, the two moving plates 7 drive the four supporting blocks 13 and the two conveying blocks 12 to move close to each other. It should be noted that the cooperation between the limiting block 8 and the limiting groove 6 during the movement of the two moving plates 7 can prevent the moving plate 7 from being deflected during the movement.

[0031] After the four supporting blocks 13 on different axes move close to the two conveying blocks 12, the stainless steel pipe is clamped between the conveying block 12 and the supporting block 13. When feeding into the annealing furnace body 1 is needed, only the driving motor 9 needs to be started to drive the two conveying blocks 12 to rotate in opposite directions through the engagement of the first gear 10 and the second gear 11, so that the steel pipe can be stably conveyed.

[0032] By setting the conical conveying block 12 and the supporting block 13, and arranging the connecting rod 15 and the abutting rod 16 below the placing rack 4, and finally arranging the two ends of the abutting rod 16 to be hinged to the connecting rod 15 and the bottom end of the moving plate 7, the user can adjust the distance between the conveying block 12 and the supporting block 13 to adapt the device to different sizes of steel pipes.

[0033] In addition, every four supporting blocks 13 and two conveying blocks 12 form a group, and the number of conveying related components in the device is not fixed, and the user can adjust it according to specific needs.

[0034] Working principle: when the device needs to convey the stainless steel pipe into the annealing furnace body 1, the user can directly place the steel pipe above the placing rack 4, and then start the electric push rod 17. After the electric push rod 17 is started, it will drive a moving plate 7 to move through the connecting block 18. Two stop rods 16 and a connecting rod 15 are arranged between the two moving plates 7. The existence of the connecting rod 15 and the stop rod 16 makes one moving plate 7 move synchronously after the other moving plate 7 is driven. Therefore, after the electric push rod 17 is started, the two moving plates 7 will drive the four supporting blocks 13 and the two conveying blocks 12 to move close to each other. It should be noted that the cooperation of the limiting block 8 and the limiting groove 6 will prevent the moving plate 7 from being skewed during movement.

[0035] After the four supporting blocks 13 on different axes move close to the two conveying blocks 12, the stainless steel pipe will be fixed between the conveying blocks 12 and the supporting blocks 13. When feeding into the annealing furnace body 1 is needed, only the driving motor 9 needs to be started to drive the two conveying blocks 12 to rotate in opposite directions through the meshing of the first gear 10 and the second gear 11, so that the steel pipe can be stably conveyed.

[0036] By setting the taper-shaped conveying blocks 12 and supporting blocks 13, and setting the connecting rod 15 and the stop rod 16 below the placing rack 4, and finally setting the two ends of the stop rod 16 to be hinged to the connecting rod 15 and the bottom end of the moving plate 7 respectively, the user can adjust the distance between the conveying blocks 12 and the supporting blocks 13 to make the device suitable for steel pipes of different sizes.
