[0026] As Figures 1 - 4 shown, a pot-hanging device for salt bath nitriding treatment of a cast iron pot includes a bottom ring 1 and further includes a pot-hanging mechanism for driving the device to rotate.

[0027] At the lower end of the bottom ring 1, an outer ring 11 is fixed. A plurality of fixing bolts 12 are arranged on the outer circumference of the outer ring 11. Above the bottom ring 1, three layered rings 13 are provided. A plurality of fixing frames 14 are arranged on the periphery between every two adjacent layered rings 13. The three layered rings 13 and the bottom ring 1 are fixedly connected through the fixing frames 14. The device can be fixed to the salt bath furnace through the arrangement of the fixing bolts 12.

[0028] The pot hanging mechanism includes a mounting frame 2. The mounting frame 2 is fixed to the upper end of the uppermost layered ring 13. A driving motor 21 is installed at the upper end of the mounting frame 2. A rotating rod 22 is fixed to the output end of the driving motor 21. Three quarter brackets 23 are fixed in the middle of the rotating rod 22. Sliders 24 are slidably connected to the four branches of each quarter bracket 23. A pot fixing structure is installed at the lower end of the slider 24. The pot fixing structure includes a plurality of low-speed motors 25. A low-speed motor 25 is installed at the lower end of each slider 24. A pot hanging frame 26 is fixed to the output end of the low-speed motor 25. One end of the pot hanging frame 26 is provided with a fixing screw 27. The threaded section of the fixing screw 27 penetrates through one end of the pot hanging frame 26 and is threadedly connected to the inner wall of the other end of the pot hanging frame 26. Three through grooves 28 are formed in the wall of the rotating rod 22. Three through holes 29 are formed in the middle of each through groove 28. A lifting block 210 is slidably connected to the bottom of each through groove 28. The lifting block 210 is slidably connected to the through groove 28 through the central round shaft thereof. An insertion rod 211 is arranged in the middle of the lifting block 210. The size of the insertion rod 211 corresponds to that of the through hole 29. Four push rods 212 are rotatably connected to the periphery of the lifting block 210. The length of the push rod 212 is the same as the length that the slider 24 can slide in the quarter bracket 23. The upper ends of the four push rods 212 are respectively hinged to the lower ends of the corresponding four sliders 24. Before the device operates, the insertion rod 211 can be pulled out according to the size of the cast iron pot, so that the lifting block 210 is not restricted. Then, through the sliding connection between the lifting block 210 and the through groove 28, the lifting block 210 is pushed upward. At this time, through the sliding connection between the slider 24 and the quarter bracket 23, when the lifting block 210 is pushed upward, the push rod 212 can push the slider 24 to move towards the outer circumference of the quarter bracket 23. When the lifting block 210 is moved to a suitable position, the insertion rod 211 is inserted into the through hole 29 in the middle or near the upper end of the through groove 28 through the lifting block 210, so that the lifting block 210 is limited again. By doing so, the distance between the four sliders 24 on the same layer is adjusted, so that the device can hang cast iron pots with larger sizes, making the applicability of the device better.

[0029] Working principle: Before the device operates, the insertion rod 211 can be pulled out according to the size of the cast iron pot, so that the lifting block 210 is not restricted. Subsequently, through the sliding connection between the lifting block 210 and the through groove 28, the lifting block 210 is pushed upward. At this time, through the sliding connection between the slider 24 and the quarter support 23, when the lifting block 210 is pushed upward, the push rod 212 can push the slider 24 to move towards the outer circle of the quarter support 23. When the lifting block 210 moves to a suitable position, the insertion rod 211 is inserted through the lifting block 210 into the through hole 29 in the middle or near the upper end of the through groove 28, so that the lifting block 210 is limited again. By doing so, the distance between the four sliders 24 on the same layer is adjusted, so that the device can hang a cast iron pot with a larger size, making the applicability of the device better. After the device is adjusted, the cast iron pot is hung at the lower end of the pot hanger 26 through the fixing screw 27. Finally, the driving motor 21 and all the low-speed motors 25 are started. After the driving motor 21 drives the rotating rod 22 to rotate, the three quarter supports 23 can rotate accordingly. After the low-speed motor 25 is started, it can drive the pot hanger 26 to rotate itself, so that the cast iron pot rotates, facilitating the salt bath treatment of the cast iron pot by the salt bath furnace.
