Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The following is in conjunction with the appendix Figure 1-7 The present invention will be further described below.

[0025] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a material retaining ring with a dispersing function for an external circulation vertical mill, including multiple sets of retaining rings 1, the top of the retaining ring 1 is provided with multiple sets of through holes 14, the inner wall of the through holes 14 is provided with threads, and the outer side of the retaining ring 1 is connected to an inner ring 2, and the inner ring 2 and the retaining ring 1 are detachably fixedly connected by bolts.

[0026] In a further design, slots 3 are provided at both ends of the retaining ring 1. A first slot 4 is provided in the slot 3, and a retaining plate 6 is inserted into the slot 3. Both the retaining plate 6 and the protruding plate 16 are arc-shaped structures. The arc-shaped structure facilitates fitting with the retaining ring 1.

[0027] In addition, anti-slip textures are provided on the outside of the card plate 6 and the convex plate 16 to increase friction and prevent slipping. The convex plate 16 is fixedly connected to both ends of the card plate 6. The convex plate 16 is inserted into the first card slot 4. A locking component is provided between the convex plate 16 and the retaining ring 1 to lock the position of the convex plate 16.

[0028] In the specific design, a mounting groove 7 is provided in the protruding plate 16. The locking component is a locking strip 8 rotatably connected to both sides of the mounting groove 7. The locking strip 8 has an arc-shaped structure and a rubber sleeve is provided on the outside of the locking strip 8. A second locking groove 5 is provided on the outside of the retaining ring 1 corresponding to the position of the locking strip 8. In addition, a lever 9 is fixedly connected to the outside of the locking strip 8. A slide rod 10 is provided through the lever 9. A locking rod 11 is fixedly connected to the top of the slide rod 10. A locking slot 15 is provided on the outside of the locking plate 6 corresponding to the position of the locking rod 11. The locking plate 6 is inserted into the groove 3, and the protruding plate 16 is inserted into the first locking groove 4. By rotating the locking strip 8, one end of the locking strip 8 is locked into the second locking groove 5. At the same time, the position of the slide rod 10 is slidably adjusted so that the locking rod 11 is locked into the locking slot 15, thereby locking the position of the locking plate 6.

[0029] In this embodiment, a limiting block 12 is fixedly connected to the bottom of the slide bar 10, and a spring 13 is sleeved on the outside of the slide bar 10. The two ends of the spring 13 are respectively connected to the push block and the limiting block 12. The push block is set to facilitate the rotation of the locking bar 8.

[0030] To ensure that those skilled in the art can fully understand the technical solution, the usage method of this embodiment is as follows:

[0031] Multiple retaining rings 1 are spliced ​​together, and then the card plate 6 is inserted into the slot 3. At the same time, the protruding plate 16 is inserted into the first card slot 4. The card strip 8 is rotated so that one end of the card strip 8 is engaged in the second card slot 5. At the same time, the position of the sliding adjustment rod 10 is slid and adjusted so that the card rod 11 is engaged in the card slot 15, thus locking the position of the card plate 6.

[0032] Following the same principle, the retaining rings 1 are locked by engaging the retaining plate 6 between two adjacent retaining rings 1.

[0033] Then install the combined retaining ring 1 inside the vertical mill.

[0034] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings.
