Detailed implementation manners

[0021] The technical solution of the present utility model will be further specifically described below through embodiments in conjunction with the accompanying drawings.

[0022] Combined with Figure 1 and Figure 2 As shown, an environmentally friendly device for removing oxide scale on the surface of stainless steel seamless steel pipes includes a housing 1 with open ends at both ends, a plurality of idler rollers 2 and a plurality of drive rollers 3 arranged at the lower end inside the housing 1, a plurality of pressure rollers 4 and an oxide scale removal mechanism arranged at the upper end inside the housing 1, and a dust suction mechanism arranged on one side of the housing 1;

[0023] One end of each of the idler rollers 2 passes through the housing 1 and is connected to a first drive mechanism. The steel pipe 6 to be processed is supported on the idler rollers 2. Each of the drive rollers 3 is connected to a second drive mechanism. The drive roller 3 abuts against the lower end of the steel pipe 6 and drives the steel pipe 6 to rotate self - axially. Each of the pressure rollers 4 is connected to the upper end inside the housing 1 in a lifting manner. The pressure roller 4 abuts against the upper end of the steel pipe 6 to limit the steel pipe 6, so as to avoid shaking of the steel pipe 6 during the process of removing oxide scale;

[0024] The oxide scale removal mechanism includes a plurality of fixed seats 7 and grinding discs 8 fixed to the bottom of the fixed seats 7. The mesh number of each of the grinding discs 8 increases sequentially from the inlet of the housing 1 to the outlet. One end of each of the grinding discs 8 facing the inlet of the housing 1 is a bevel surface to facilitate the passage of the steel pipe 6;

[0025] A plurality of openings 9 are provided on one side of the bottom of the housing 1, and the dust suction mechanism is connected to each of the openings 9.

[0026] The working principle of the above - mentioned structure is as follows: The stainless steel seamless steel pipe 6 to be removed of oxide scale is inserted from the inlet of the housing 1. The steel pipe 6 is supported on the idler rollers 2, limited by the pressure rollers 4, and displaced towards the outlet of the housing 1 along with the self - rotation of the idler rollers 2. During the axial displacement of the steel pipe 6, it also rotates radially under the action of the drive rollers 3. When passing under each of the grinding discs 8, it generates friction with each of the grinding discs 8, and the oxide scale is removed. The oxide scale debris ground off falls to the bottom of the housing 1 and is sucked out of the housing 1 by the dust suction mechanism.

[0027] The beneficial effects of the above structure are as follows: The structure is simple. The scale removal of the stainless steel seamless pipe 6 is carried out in a pure mechanical manner. The scale debris ground off drops to the bottom of the housing 1 and is sucked out of the housing 1 by the dust suction mechanism. After collection, it can be centrally processed or recycled, without causing pollution to the outside world, which is more environmentally friendly. The mesh numbers of the grinding discs 8 increase sequentially from the inlet to the outlet of the housing 1. Since the mesh number of the grinding disc 8 at the outermost end reaches 1500 meshes, when the stainless steel seamless pipe 6 exits the housing 1, it is actually polished, and subsequent processing steps can be omitted, improving the reuse efficiency of the stainless steel seamless pipe 6.

[0028] In another embodiment, in combination with Figure 1 and Figure 2 as shown, the first driving mechanism includes a first driving motor 10 and a transmission chain. One end of each roller 2 passing through the housing 1 is respectively provided with a first transmission wheel. The transmission chain is connected to each first transmission wheel, and the first driving motor 10 is connected to one of the rollers 2.

[0029] In another embodiment, as shown in Figure 2 a protective cover 11 is further provided on one side of the housing 1, and each first transmission wheel and the transmission chain are arranged inside the protective cover 11.

[0030] In another embodiment, as shown in Figure 1 the second driving mechanism includes a second driving motor 12 and a transmission shaft 13. The transmission shaft 13 is arranged below each roller 2. The transmission shaft 13 is arranged along the length direction of the housing 1. A plurality of second transmission wheels corresponding to the driving rollers 3 are fixed on the transmission shaft 13. Each driving roller 3 is respectively rotatably connected to a plurality of brackets 14. One end of each driving roller 3 is further provided with a third transmission wheel. Each second transmission wheel is connected to the corresponding third transmission wheel through a transmission belt. Thus, the second driving motor 12 drives each driving roller 3 to rotate through the transmission shaft 13.

[0031] In another embodiment, as shown in Figure 1 through holes corresponding to the transmission shaft 13 are respectively provided in the middle of each bracket 14. Bearings are arranged in the through holes, and the transmission shaft 13 is connected to each bearing to prevent the transmission shaft 13 from being bent.

[0032] In another embodiment, in combination with Figure 1 and Figure 2 as shown, each pressing roller 4 is rotatably connected to a moving seat 15. A slideway corresponding to the moving seat 15 is provided at the upper end inside the housing 1. The moving seat 15 moves up and down along the slideway. A screw rod 16 is further rotatably connected to the top of the moving seat 15. The screw rod 16 is screwed to the top of the housing 1. Rotating the screw rod 16 can drive the moving seat 15 to move, thereby adjusting the height of the pressing roller 4.

[0033] In another embodiment, in combination with Figure 1 and Figure 2 as shown, a turning handle 17 is also fixed to the top of each screw rod 16.

[0034] In another embodiment, in combination with Figure 1 and Figure 2 as described, an installation opening corresponding to each fixing seat 7 is provided at the top of the housing 1, and each fixing seat 7 is inserted into and fixed at the upper end of the housing 1 through the installation opening, so as to facilitate the removal of the fixing seat 7 to replace the grinding disc 8, or replace the fixing seat 7 with a suitable length according to the height of the pressure roller 4.

[0035] In another embodiment, as Figure 1 shown, one end of the fixing seat 7 facing the inlet of the housing 1 is also beveled to avoid rigid collision between the fixing seat 7 and the steel pipe 6, and an elastic layer is further provided between the grinding disc 8 and the fixing seat 7, which can adapt to a certain processing error.

[0036] In another embodiment, as Figure 2 shown, the dust suction mechanism includes a connection channel 18, a negative pressure fan and a dust collection box 19. The connection channel 18 connects each opening 9. There are multiple groups of the negative pressure fans and the dust collection boxes 19. The negative pressure fan is arranged at the connection between the dust collection box 19 and the connection channel 18. A filter element is provided at the outlet end of the dust collection box 19 to ensure the dust suction effect and prevent the scale debris from being discharged into the workshop.
