[0010] The utility model has the following beneficial effects:

[0011] The first locating sleeve and the second locating sleeve are arranged around the copper tube so that the fixing groove fits with the copper tube and the groove and the protrusion are aligned. Then the two fixing seats are placed outside the first locating sleeve and the second locating sleeve, and the fixing block fits with the middle part of the first locating sleeve and the second locating sleeve. The locating block is clamped in the locating groove. Finally, the positions of the two relatively placed fixing seats are fixed by bolts. At this time, the spring is compressed under force, providing a stretching force, so that the fixing block presses against the first locating sleeve and the second locating sleeve, increasing the stability of the fixation. Since the outer sleeve and the inner sleeve are made of phenolic cloth board material, the spring is specifically an insulating spring, so that the device has good insulation performance to prevent the copper tube from being deformed due to force and heat, thereby affecting production.

DETAILED DESCRIPTION

[0020] See also Figures 1 to 7, a conductive copper tube tube seat of an ore-heating furnace is composed of an outer sleeve 1 and an inner sleeve 2 arranged in the outer sleeve 1. The outer sleeve 1 includes a fixed seat 3 and a fixed block 4. The fixed seat 3 is provided with two and arranged relatively. One side of the fixed seat 3 is penetrated with two connecting holes 16, and a semicircular fixing groove 5 is penetrated on the fixed seat 3. A sliding hole 6 is provided on the fixing groove 5. A semicircular limiting groove 7 is provided in the middle of the fixing groove 5. The end face of the fixing block 4 is arc-shaped and matched with the limiting groove 7. A sliding rod 8 is provided on one side of the fixing block 4. The sliding rod 8 is located in the sliding hole 6 and is connected with a spring 9. One end of the spring 9 is connected to the end of the sliding hole 6; the inner sleeve 2 includes a first positioning sleeve 10 and a second positioning sleeve 11. The first positioning sleeve 10 and the second positioning sleeve 11 are both matched with the fixing groove 5. The two end faces of the first positioning sleeve 10 are provided with an I-shaped groove 12, and the two ends of the second positioning sleeve 11 are provided with a convex block 13 matched with the groove 12.
