[0002] The application environment of large-diameter petroleum steel pipes is relatively harsh, and producers generally use external surface anti-corrosion methods to protect large-diameter petroleum steel pipes; oil and gas pipelines need to be covered with a thicker anti-corrosion layer, generally PE anti-corrosion, and offshore drilling pipes are treated with surface spray painting to achieve the purpose of corrosion protection. After spraying the large-diameter water-proof pipe, the surface paint needs to be dried.

[0003] For example, a drying device for spraying disclosed in Chinese patent CN211359473U places a large-diameter water-blocking tube sprayed with paint on a conveyor belt, rotates the motor to work, and drives the active roller connected to its output end to rotate, thereby driving the large-diameter water-blocking tube placed on the conveyor belt to enter the drying chamber from the inlet, the drying component works, the electric heater heats up, and the blower works to blow the heat generated by the electric heater in the conveying direction, thereby drying the painted material placed on the conveyor belt, and the dried material is discharged from the drying chamber through the outlet, thereby replacing natural air drying and accelerating the drying efficiency.

[0004] However, when the device is used to dry the large-diameter water-blocking conduit, the surface of the large-diameter water-blocking conduit is heated unevenly, resulting in uneven drying of the large-diameter water-blocking conduit.

[0005] For this reason, we urgently need to provide a drying device for spraying large-diameter water-blocking conduit. Utility Model Content

The large-diameter water-blocking conduit is supported by the roller 402. The support 1 403 is fixedly installed on the left side of the left base 1, the support 2 404 is fixedly installed on the right side of the right base 1, the motor 405 is fixedly installed on the top of the support 1 403, one end of the driving shaft 406 is fixedly installed on the output end of the motor 405, the driven shaft 407 is rotatably connected to the upper end of the inside of the support 2 404, and the shell 408 is fixedly installed on The right end of the driving shaft 406 and the left end of the driven shaft 407, and the connecting rod 409 are rotatably connected to the inside of the shell 408. The front and rear sides of the connecting rod 409 are provided with external threads in opposite directions, and two clamping plates 410 are threadedly connected to the outer surface of the connecting rod 409. By rotating the connecting rod 409 and threading it with the front and rear clamping plates 410, the clamping plates 410 are moved in opposite directions, so that the clamping plates 410 abut against the inner wall of the large-diameter water-proof duct, thereby facilitating the rotation of the large-diameter water-proof duct. The clamping plates 410 are installed at the front and rear ends of the outer side of the connecting rod 409, and rubber pads are fixedly installed on the contact surfaces between the front and rear clamping plates 410 and the inner wall of the large-diameter water-proof duct. The rubber pads can prevent the inner wall of the large-diameter water-proof duct from being scratched when the clamping plates 410 abut against the inner wall of the large-diameter water-proof duct. Example

[0029] On the basis of Example 1: the drying unit includes a blower 501, a box 502 and a heating wire 503. The blower 501 is fixedly installed on the top of the top plate 3. The output end of the blower 501 extends to the inside of the box 502, and a rectangular ventilation hole is opened on the lower surface of the box 502, so that the wind blown by the blower 501 is blown to the surface of the large-diameter water-proof duct through the rectangular ventilation hole, thereby accelerating the drying of the paint on the surface of the large-diameter water-proof duct. The box 502 is fixedly installed on the bottom of the top plate 3, and the heating wire 503 is installed inside the box 502. The heating wire 503 is connected to the power supply through a wire, and the heating wire 503 is energized by the power supply to make the heating wire 503 heat up, thereby heating the wind blown by the blower 501, so that the hot air dries the paint on the surface of the large-diameter water-proof duct, thereby improving the drying efficiency.

[0031] When in use, the large-diameter water-blocking tube to be dried after spraying is placed on the top of the roller 402, and then the connecting rod 409 is turned. When the connecting rod 409 rotates, it is threadedly connected with the clamping plate 410, so that the front and rear clamping plates 410 move in opposite directions until the clamping plate 410 abuts against the inner wall of the large-diameter water-blocking tube to clamp the large-diameter water-blocking tube. Then, the blower 501 is started, and the power is turned on to energize the heating wire 503 at the same time, so that the heating wire 503 heats the wind blown out by the blower 501, and the hot wind is blown to the surface of the large-diameter water-blocking tube for drying. Then the motor 405 is started to drive the driving shaft 406 to rotate, so that the large-diameter water-blocking tube rotates, and the large-diameter water-blocking tube is dried more evenly. In addition, since the base 1 is at a lower height from the ground, it is convenient to place the large-diameter water-blocking tube on the top of the roller 402, which is easy to operate and has high drying efficiency.
