[0026] When the above-mentioned drying equipment is in use, one end of the stainless steel tube is sealed and plugged into the plug hole 204, and the blowing head 5 is sealed and plugged into the other end of the stainless steel tube, so that the two ends of the stainless steel tube are sealed, thereby reducing the amount of dust entering the interior of the stainless steel tube during the drying process and improving the cleanliness of the inner wall of the stainless steel tube after drying; during the drying process, the air pump 4 provides power to circulate the airflow between the dust removal box 3 and the stainless steel tube, and the moisture on the inner wall of the stainless steel tube is dried by the airflow to achieve the drying of the stainless steel tube. During the airflow circulation process, the dust and impurities in the airflow are filtered by the dust removal filter element 303, thereby further reducing the amount of dust inside the stainless steel tube, improving the cleanliness of the inner wall of the stainless steel tube after drying, and improving the quality of the finished stainless steel tube.

[0027] In the above-mentioned drying equipment, the airflow gathers water to the drainage branch, and under the action of gravity, the water is discharged through the drainage branch, thereby improving the drying effect of the stainless steel pipe; the protective gas filled into the dust removal box 3 can be nitrogen, and the nitrogen can slow down the oxidation rate of the inner wall of the stainless steel pipe during the drying process, play a protective role, so as to improve the quality of the finished stainless steel pipe; after the drying is completed, the self-sealing mechanism closes the exhaust branch, and the valve 501 is closed to close the air blowing head 5, thereby reducing the probability of dust entering the dust removal box and the exhaust branch, so as to improve the cleanliness of the airflow circulation pipeline, and finally improve the cleanliness of the airflow during the drying of the stainless steel pipe, improve the cleanliness of the stainless steel pipe, and the closed pipeline can also prevent the protective gas from leaking, thereby reducing production costs.

[0028] A further improvement is, Figure 1 and 3 As shown, the dust removal box 3 includes a tubular box body 301, and both ends of the box body 301 are sealed with end covers 302, one of the end covers 302 is connected to the exhaust branch through the return pipe 601, and the other end cover 302 is connected to the air blowing head 5 through the air blowing pipe 602, and the air pump 4 is installed at the connection between the air blowing pipe 602 and the end cover 302.

[0030] A further improvement is, Figure 2 As shown, the air inlet end of the valve 501 is connected to the air blowing pipe 602, and the air outlet end of the valve 501 is fixedly connected to a plug-in tube 502 that plugs into the end of the stainless steel pipe, and a sealing ring is sleeved on the outer periphery of the plug-in tube 502. The plug-in tube 502 is plugged into the inside of the end of the stainless steel pipe to achieve connection with the stainless steel pipe, and the opening and closing of the air blowing head 201 is controlled by the valve 501, thereby effectively preventing the loss of protective gas and preventing dust from entering the inside of the air blowing head 201.

[0031] A further improvement is, Figure 4 and 5 As shown, the exhaust branch includes an exhaust hole 209 opened at the top of the plug hole 204, and the exhaust hole 209 is connected to the return pipe 601.

The setting of the sealing cover 206 is conducive to the maintenance of the internal components of the plug hole 204. The sealing sleeve 205 can realize the sealed connection between the stainless steel tube and the plug hole 204. When the stainless steel tube is inserted into the plug hole 204, the stainless steel tube pushes the sliding sleeve 206 to move to one side of the exhaust hole 209, so that the exhaust hole 209 is opened, so that the air flow can circulate inside the stainless steel tube and the dust removal box 3 to achieve drying of the stainless steel tube; when the drying is completed, the two ends of the stainless steel tube are separated from the plug hole 204 and the nozzle 5 respectively, and a sealing plug is quickly set at the end of the stainless steel tube to keep the inside of the stainless steel tube clean. At this time, the sliding sleeve 206 is pushed to reset under the action of the elastic force of the spring 207, so that the sliding sleeve 206 covers the exhaust hole 209, thereby preventing dust from entering and reducing the loss of protective gas.

[0034] A further improvement is, Figure 1 As shown, the connection seat 2 is fixedly connected with a pipe rack 1 for placing stainless steel pipes, the height of the top surface of the pipe rack 1 gradually decreases from the front end to the rear end, the connection seat 2 is connected to the rear end of the pipe rack 1, the drainage hole 201 is arranged adjacent to the sealing cover 208, and the distance between the drainage hole 201 and the exhaust hole 209 is greater than the length of the sliding sleeve 206, which can prevent the sliding sleeve 206 from blocking the drainage hole 21. The pipe rack 1 is used to place and position the stainless steel pipe, and the inclined pipe rack 1 is conducive to the water inside the stainless steel pipe to flow into the drainage hole 201 under the action of gravity, thereby improving the drying efficiency.
