[0017] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0018] The following refers to the location Figure 1 The position of each component in the figure is taken as the reference.

[0019] like Figure 1 , Figure 2As shown, the utility model is used for thermal spraying of the surface of a precious metal smelting channel, comprising an inflatable sealing ring 1, a transverse connecting plate and a connecting rotating chuck 2, the inflatable sealing ring 1 is provided with an air filling and deflation nozzle, one end of the transverse connecting plate is connected to the side of the inflatable sealing ring 1, and the connecting rotating chuck 2 is arranged on the transverse connecting plate.

[0020] When the surface of the precious metal smelting channel 8 is thermally sprayed, the rotating chuck 2 is connected to the three-claw chuck driven by the motor, so that the entire sealing and plugging device can rotate with the three-claw chuck, and a sealing and plugging device is respectively provided at the openings at both ends of the precious metal smelting channel 8, and the inflatable sealing and plugging ring 1 is inflated to seal the openings. Figure 3 As shown, the possibility of spray powder entering the precious metal smelting channel 8 is effectively reduced. In addition, the sealing and plugging device can rotate with the three-claw chuck, so that the precious metal smelting channel 8 can also rotate with the three-claw chuck. The rotation of the precious metal smelting channel 8 facilitates spraying, thereby improving the efficiency and quality of spraying.

[0021] After compressed air is introduced into the inflatable sealing ring 1 through the inflating and discharging nozzle, the inflatable sealing ring 1 expands, making it contact with the inner wall of the precious metal smelting channel 8 to form a sealing structure. Figure 3 As shown. During spraying, the center temperature of the spray gun can reach over 2000°C, and the inner wall of the precious metal smelting channel 8 can reach a high temperature of about 200°C. In order to ensure the use effect of the inflatable sealing ring 1, the inflatable sealing ring 1 is preferably made of silicone material, which can withstand a high temperature of 500°C.

[0022] In order to improve the overall strength of the inflatable sealing ring 1 and increase its service life and effect, reinforcement plates 3 are respectively provided on the left and right sides of the inflatable sealing ring 1.

[0023] In order to facilitate the charging and discharging of compressed air to the inflatable sealing ring 1, a switch valve 4 is provided on the charging and discharging nozzle, and the charging and discharging of compressed air is controlled by the switch valve 4. In order to improve the installation firmness of the switch valve 4, the switch valve 4 is arranged on the transverse connecting plate.

[0024] The transverse connecting plate serves to connect the inflatable sealing ring 1 and the connecting rotating chuck 2, so that when the sealing and plugging device is in use, the inflatable sealing ring 1 is located inside the precious metal smelting channel 8, and the connecting rotating chuck 2 is located outside the precious metal smelting channel 8. In order to facilitate the use of the transverse connecting plate and the arrangement of the inflatable sealing ring 1 and the connecting rotating chuck 2, a preferred structure of the transverse connecting plate of the utility model is: Figure 1 , Figure 2As shown, the transverse connecting plate includes a transverse plate portion 5 and a vertical plate portion 6 connected together from left to right, one end of the transverse plate portion 5 is connected to the side of the inflatable sealing ring 1, and the connecting rotating chuck 2 is arranged on the side of the vertical plate portion 6.
