Description

Technical Field

[0001] The utility model relates to the technical field of ball mills, in particular to an alloy powder ball mill for preparing an anti-scorching and sticking coating. Background Art

[0002] The ball mill is the key equipment for crushing materials after they are broken. This type of ball mill is equipped with a certain number of steel balls as grinding media in its cylinder. It is widely used in non-ferrous metal beneficiation and preparation of anti-scorching coatings and other production industries. The ball mill grinds the molten block into powder. For example, the preparation of the anti-scorching coating of model FSZ-011 requires the use of a corresponding ball mill to grind and crush the material.

[0003] By comparing with a high-efficiency ball mill with patent announcement number CN219168575U, in this scheme, the molten block powder can be quickly discharged through the coordinated use of the connecting plate and the slide, and the slide can also be guided by the guide rod, thereby improving the guiding effect of the device. However, when this device crushes the material, the crushed material in the cylinder may have powders of different particle sizes, and unqualified powder and qualified powder will be gathered together. If the qualified powder is not discharged in time, in the continuous grinding process, the unqualified powder may be mixed in a large amount of qualified powder, which is not conducive to sufficient grinding and crushing of the unqualified powder. The qualified powder may affect the crushing effect of the unqualified powder, increase the crushing time of the material, and then reduce the efficiency of the material crushing, and the material may be unevenly crushed.

[0027] The screening component includes a plurality of sieve plates 205 arranged between two adjacent partitions 206. The sieve plates 205 are arc-shaped, and a plurality of sieve holes 214 are provided at the upper end of the sieve plates 205. The sieve plates 205 are slidably connected to the inner cylinder 202. A plurality of compression springs 213 are connected between the sieve plates 205 and the inner cylinder 202. A discharge trough 207 is provided on the inner wall of the inner cylinder 202 near the sieve plates 205. A clearing component for clearing the sieve holes 214 on the sieve plates 205 is provided at the bottom end of the outer cylinder 201 near the sieve plates 205.

[0028] The unclogging component includes a feed trough 209 opened at the bottom end of the outer cylinder 201 near the screen plate 205, a plurality of connecting plates 218 are fixed on the side wall of the feed trough 209, a plurality of ejector pins 208 are fixed on the upper end of the connecting plate 218, the diameter of the ejector pins 208 is smaller than the diameter of the screen hole 214, and the position of the screen hole 214 corresponds to the position of the ejector pins 208.

[0029] The collecting component includes a collecting frame 210 arranged at the lower end of the outer cylinder 201, and a collecting box 212 is slidably installed at the bottom end of the collecting frame 210.

At the same time, when the steel ball falls, it will knock on the screening component to prompt the screening component to move downward, so that the dredging component is used to dredge the powder blocked in the screening component to keep the powder discharge unobstructed.

[0030] In this embodiment, the shock absorbing mechanism includes a plurality of damping rods 301 arranged at the lower end of the base plate 100 , a base 303 is fixed to the bottom end of the damping rod 301 , and a buffer spring 302 is arranged on the outer side of the damping rod 301 .

[0033] Thereby, unqualified powder continues to remain on the sieve plate 205, and the unqualified material continues to be ground by steel balls. When the steel balls continue to fall and hit the surface of the sieve plate 205, the sieve plate 205 will be driven to move downward, and then the multiple sieve holes 214 on the sieve plate 205 are cleared by the multiple ejector pins 208 on the multiple connecting plates 218 at the bottom end of the outer cylinder 201, thereby reducing the blockage of the sieve holes 214 by the powder and maintaining smooth powder feeding. At the same time, the elastic connection between the sieve plate 205 and the inner cylinder 202 is utilized to effectively reduce the impact force of the steel balls on the sieve plate 205, thereby improving the service durability of the sieve plate 205, and separating qualified powder from unqualified powder by screening, thereby effectively avoiding the influence of qualified powder on the grinding of unqualified powder, reducing the material crushing time, and increasing the material crushing efficiency.
