[0021] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.

[0022] As Figures 1-3As shown in the figure, a magnetic substance and oil stain collection protective cover for bearing wear of a granulation roll mill provided in this embodiment includes a gearbox seat 1 and a support box seat 13. On one side of the outer walls of the gearbox seat 1 and the support box seat 13, a powder collection box 3 is welded. A main shaft 7 is also rotatably connected through the gearbox seat 1 and the support box seat 13. The gearbox seat 1 is externally connected to a driving device to drive the main shaft 7 to rotate, and the support box seat 13 is used to support the stable rotation of the other end of the main shaft 7. The same bearing oil seal 11 is also provided;

[0023] A draw cover 4 is slidably connected to the top of the powder collection box 3, and a side cover 5 is hinged on the side wall of the powder collection box 3. The draw cover 4 is limited and slides through the top chute to observe the internal powder collection situation after being opened. The side cover 5 can be opened through a lock 6 to clean the stored powder inside;

[0024] A second sealing silicone pad 12 clamped on the outer wall of the main shaft 7 is provided in one group of the powder collection boxes 3. The second sealing silicone pad 12 serves the purpose of preventing lubricating oil from leaking and at the same time conducts heat to the main shaft 7.

[0025] A bearing oil seal 11 extends on the outer wall of the gearbox seat 1, and the main shaft 7 rotates through the bearing oil seal 11. The second sealing silicone pad 12 is closely attached to one side of the bearing oil seal 11.

[0026] A clamp 9 is detachably installed around the second sealing silicone pad 12, and a roll 2 is detachably installed in the middle part of the main shaft 7. The clamp 9 can adjust and clamp the second sealing silicone pad 12.

[0027] A first sealing silicone pad 8 is clamped and fixed in the wall of the powder collection box 3 close to the roll 2. The main shaft 7 is rotatably connected to the inner wall of the first sealing silicone pad 8. The first sealing silicone pad 8 serves to conduct heat to the main shaft 7 and reduce friction with the powder collection box 3.

[0028] A scraper 10 is provided between the first sealing silicone pad 8 and the second sealing silicone pad 12. The blade of the scraper 10 contacts the outer wall of the main shaft 7, and the top of the scraper 10 is detachably fixed on the outer wall of the bearing oil seal 11.

[0029] A lock 6 is cooperatively installed on the outer wall of the side cover 5 and the outer wall of the powder collection box 3.

[0030] The working principle of this device:

[0031] The first step: When this device is specifically used, the roll 2 is connected to the main shaft 7 by a driving device outside the gearbox seat 1, and after speed change, it drives the rotation to cooperate with the friction assembly to frictionally crush the material;

[0032] Step 2: During the crushing process, powder debris will adhere to the outer wall of the main shaft 7 and enter the powder collection box 3 through the gap between the first sealed silicone gasket 8 and the main shaft 7. Some of them will directly fall onto the bottom inside the box, and some will continue to adhere to the main shaft 7. At this time, they will be scraped off by the scraper 10 fixed on one side to keep the main shaft 7 clean. In addition, at the position where the main shaft 7 is connected to the bearing oil seal 11, the second sealed silicone gasket 12 is clamped by the clamp 9. Synchronously with the rotation of the main shaft 7, it plays a secondary sealing role for the oil seal, preventing the leakage of lubricating oil and avoiding the pollution of powder debris.

[0033] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
