[0006] By adopting the above technical scheme, the polyurethane thermal insulation pipe is fixed on the fixed frame, and then the conveying device on the conveying frame is started to move the moving rod, and the dust collection ring and the grinding disc installed at one end of the moving rod enter the polyurethane thermal insulation pipe. When the motor is started to drive the grinding disc to rotate for rust removal, the vacuum cleaner installed in the collection box is started, so that the rust powder generated by rust removal is sucked in through the dust collection holes opened on the wall of the dust collection ring, and the rust powder is collected by cooperating with the filter net installed at the air inlet of the vacuum cleaner.

The dust collection ring 7 and the grinding disc 8 installed at one end of the moving rod 6 enter the polyurethane thermal insulation pipe. When the motor 13 is started to drive the grinding disc 8 to rotate for rust removal, the vacuum cleaner 15 installed in the collecting box 9 is started, so that the rust powder generated by rust removal is sucked in through the dust collection holes 14 opened on the ring wall of the dust collection ring 7, and the rust powder is collected by the filter installed at the air inlet of the vacuum cleaner 15. When the production device is performing rust removal processing on the polyurethane thermal insulation pipe, the rust powder generated by rust removal can be vacuumed and collected to avoid the problem of rust powder flying around to make the working environment worse and being easily inhaled by the staff to affect their health.

[0026] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , a gear 11 is installed on the fixed frame 2, and the gear 11 is meshed with a toothed plate 12 installed on the fixed frame 2, and the toothed plate 12 is connected to a clamping ring 16. By starting the gear bidirectional motor to rotate forward and reverse, the gear 11 and the toothed plate 12 meshed therewith are matched to drive the two groups of clamping rings 16 to move relative to each other to fix and disassemble the polyurethane thermal insulation pipe. A motor A10 is installed on the conveying frame 3, and two groups of conveying wheels 4 are installed on the conveying frame 3. The bottom of the two groups of conveying wheels 4 are equipped with mutually meshing toothed rings, and the power shaft end of the motor A10 is connected to the toothed ring at the bottom of the conveying wheel 4. When the motor A10 is started to rotate forward and reverse, the power shaft end of the motor A10 is connected to the toothed ring at the bottom of the conveying wheel 4. Because the toothed rings installed at the bottom of the two groups of conveying wheels 4 are meshed with each other, the two groups of conveying wheels 4 rotate relative to each other, thereby transmitting and moving the moving rod 6 fitted between the two groups of conveying wheels 4, so that the grinding disc 8 moves in the polyurethane thermal insulation pipe for rust removal.

When the motor 13 is started to drive the grinding disc 8 to rotate for rust removal, the vacuum cleaner 15 installed in the collecting box 9 is started, so that the rust powder generated by rust removal is sucked in through the dust collection holes 14 opened on the ring wall of the dust collection ring 7, and the rust powder is collected by the filter installed at the air inlet of the vacuum cleaner 15.
