[0024] When using it for the first time, water can be filled in the water collecting funnel 11 in advance, and under the action of the water pump 14, the water source in the water collecting funnel 11 can be injected into the water pipe 15 after passing through the water suction hose 12 and the water purification box 13.

Support legs 32 are fixedly installed on the front and rear sides of the opposite back surfaces of the two roller brackets 31. A roller driving motor 34 is fixedly installed on the front side of the right end of the right roller bracket 31. The roller driving motor 34 is used to drive the plurality of conveying rollers 33 to rotate in conjunction. A conveying mechanism 35 is fixedly installed below the right end of the left roller bracket 31. The conveying mechanism 35 is located below the plurality of conveying rollers 33. The conveying mechanism 35 includes a driving box 351, and the driving box 351 is fixedly installed on the right side of the left roller bracket 31. At the end, an electric push rod 352 is fixedly installed at the bottom of the driving box 351, and the telescopic output end of the electric push rod 352 penetrates into the inner cavity of the driving box 351 and is fixedly installed with a lifting plate 353. A slide groove is opened on the right side of the driving box 351, and the lifting plate 353 penetrates the slide groove to the right side of the driving box 351 and is fixedly installed with a connecting long plate 354.

[0028] By placing the stainless steel pipe horizontally in the gap between the two conveying rollers 33 between the two roller brackets 31, and using the roller driving motor 34 to drive the conveying roller 33 to rotate, the stainless steel pipe can rotate under the rotation of the front and rear conveying rollers 33, and at the same time, by starting the electric push rod 352 at the bottom of the driving box 351, the lifting plate 353 can drive the connecting long plate 354 to move upward, so that the inclined top plate 357 on the top vertical plate 356 of the plurality of bottom rods 355 is pushed upward. Since the inclined top plate 357 is tilted backward, it will push the stainless steel pipe between the conveying rollers 33 forward when it rises, and then put the stainless steel pipe again. By analogy, multiple stainless steel pipes can be simultaneously rotated and conveyed.

[0029] The following is a detailed description of the working principle of the annealing furnace used in the production of stainless steel pipes.

[0030] like Figure 1-6As shown, by placing the stainless steel pipe horizontally in the gap between the two conveying rollers 33 between the two roller brackets 31, and using the roller driving motor 34 to drive the conveying roller 33 to rotate, the stainless steel pipe can rotate under the rotation of the front and rear conveying rollers 33, and at the same time, by starting the electric push rod 352 at the bottom of the driving box 351, the lifting plate 353 can drive the connecting long plate 354 to move upward, so that the inclined top plate 357 on the top vertical plate 356 of the plurality of bottom rods 355 is pushed upward. Since the inclined top plate 357 is tilted backward, it will push the stainless steel pipe between the conveying rollers 33 forward when it rises, and then the stainless steel pipe is put in again, and so on. When using it for the first time, water can be filled in the water collecting funnel 11 in advance, that is, under the action of the water pump 14, the water source in the water collecting funnel 11 passes through the water suction hose 12 and the water purification box 13, and is injected into the water spray head 27 in the box body 21 through the water delivery pipe 15. When the stainless steel pipe moves When it reaches the bottom of the box body 21, the reciprocating screw 23 is driven to rotate by the rotating motor 22, so that the movable plate 24 used to fix the water spray head 27 uses the sliding limit of the slide rod 25 to perform left and right reciprocating motion, so that the water supply pipe 15 injects the water sprayed by the water spray head 27 through the water supply hose 26 to spray and dissipate heat to the rotating stainless steel pipe passing through the box body 21, and the waste water can enter the water collecting funnel 11 again, and when it is sucked from the water suction hose 12 by the water pump 14, the impurities are filtered through the water filter cartridge 125, and the clean water source can be extracted through the water purification box 13. When it is necessary to clean the impurities in the water filter cartridge 125, the threaded ring 123 on the top of the movable disk 121 can be rotated and removed, so as to disengage from the threaded hole 131 at the bottom of the water purification box 13, and then the mounting ring 124 can be rotated again to separate the water filter cartridge 125 from the threaded ring 123, so that the inside of the water filter cartridge 125 can be cleaned directly, and after cleaning, it can be rotated and installed back in sequence.

[0031] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
