Description

Technical Field

[0001] The utility model relates to a wet-type grid bearing ball mill, belonging to the technical field of wet-type grid ball mills. Background Art

[0002] The ball mill is a key equipment for crushing materials after they are broken. This type of grinding machine is a machine that has a certain number of steel balls as grinding media in its cylinder. It can be divided into two types of grinding methods: dry and wet. The wet grid ball mill is one of them.

[0003] For example, the wear-resistant wet grate ball mill with patent publication number CN201920399888.9 includes an end liner, a feed bushing and an end cover. A wear-resistant part is arranged on the end liner. The wear-resistant part is arranged in the range of 1 / 2 to 3 / 4 of the lower part of the end liner. The wear-resistant part is a first reinforcing rib and a second reinforcing rib which are arranged symmetrically on the left and right. The first reinforcing rib and the second reinforcing rib are arranged parallel to the hypotenuse of the end liner. The first reinforcing rib and the second reinforcing rib are stepped, and transition arcs are arranged at the positions where the steps are connected. The wear-resistant part can also be a wear-resistant boss, and the surface of the wear-resistant boss is arc-shaped, and a plurality of guide grooves are arranged on the wear-resistant boss. The bottom of the end liner is installed above the feed bushing, and an elastic part is arranged at the junction of the feed bushing and the end liner. One end of the elastic part is fixed inside the feed bushing, and the other end abuts against the end liner.

[0004] Since the above-mentioned wet grate ball mill rotates its central axis to grind the material, the material after feeding may splash out under the drive of the rotating wet grate ball mill, and the grinding balls inside the wet grate ball mill may hit the vertical grate plate during the rotation, which indirectly affects the practicality of the wet grate ball mill for grinding materials and brings certain adverse effects to actual use, so it needs to be improved. Utility Model Content

The utility model arranges three layers of earthquake-resistant grid plates inside the wet grid ball mill, so as to screen and dredge the materials after grinding and provide earthquake-resistant resistance to the grinding balls. A splash-proof feed pipe is added for splash-proof treatment at the feed point, thereby enhancing the splash-proof feed of the wet grid ball mill and the pressure-resistant and shock-absorbing effect at the internal grid plates, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1 Please refer to Figure 1-Figure 5 , the utility model provides a technical solution:

[0025] A wet grid bearing ball mill comprises a support base 1, a bearing rotating frame 2 is fixedly mounted on the top of the support base 1, a wet grid ball mill body 3 is rotatably connected to the inner wall of the bearing rotating frame 2, a driving motor 4 is fixedly mounted on the top of the support base 1 near the right side thereof, a reducer 5 with a driving gear is fixedly connected to the output end of the driving motor 4, a driven gear 6 is fixedly mounted on the right side of the wet grid ball mill body 3, the surface of the driven gear 6 is rotatably connected to the driving gear on the reducer 5, a splash-proof feed pipe 7 is fixedly connected to the right side of the wet grid ball mill body 3, and a shock-absorbing grid mesh plate 8 is fixedly connected to the inner wall of the wet grid ball mill body 3.

[0026] Specifically, Figure 1-Figure 5 As shown, a shock-absorbing pad 9 is fixedly connected to the bottom of the support seat 1, and the lower surface of the shock-absorbing pad 9 is coated with a wear-resistant coating, which increases the shock-absorbing pad 9 for the support seat 1 and the wet grid ball mill body 3 thereon.

[0027] Specifically, Figure 1-Figure 5 As shown, the main body of the splash-proof feed pipe 7 is a circular tube, and the inner wall of the circular tube is fixedly connected with an annular shrinking plate 10, and the diameter of the annular shrinking plate 10 decreases from left to right. The setting of the annular shrinking plate 10 can reduce the situation of the material splashing into the splash-proof feed pipe 7. The right side of the inner wall of the wet grid ball mill body 3 is fixedly connected with a spiral guide rod 11, and the right side of the wet grid ball mill body 3 close to the inner wall is fixedly connected with a smooth guide plate 12, and the smooth guide plate 12 is annularly sleeved on the outside of the spiral guide rod 11 as a whole. The wet grid ball mill body 3 in a rotating state can drive the spiral guide rod 11 to rotate, and guide the movement of the material at the feed port on the wet grid ball mill body 3. The addition of the smooth guide plate 12 can help the material to smoothly enter the internal main body space of the wet grid ball mill body 3.

[0028] Example 2 Please refer to Figure 1-Figure 5The difference between this embodiment and embodiment 1 is that the number of the shock-absorbing lattice mesh plates 8 is three, and the three shock-absorbing lattice plates are respectively connected to the left side, the middle and the right side of the inner wall of the wet lattice ball mill body 3, and the lattice spacing gaps of the three shock-absorbing lattice plates are different in size. The main body of the shock-absorbing grating mesh plate 8 is a shock-resistant and firm plate 13, and a guide groove 14 is provided on the top of the inner wall of the shock-resistant and firm plate 13. Two wear-resistant grating plate bodies 15 are slidably connected to the inner wall of the guide groove 14, and a shock absorber 16 is fixedly connected between the two wear-resistant grating plate bodies 15. The outer part of the shock absorber 16 is sleeved with a sealing protective sleeve 17. The wear-resistant grating plate bodies 15 on the shock-absorbing grating mesh plate 8 will use the shock absorber 16 to absorb shock and buffer the force under impact. Under the guidance of the guide groove 14, the tilting of the wear-resistant grating plate body 15 during the activity is reduced. The addition of the sealing protective sleeve 17 can wrap and protect the shock absorber 16, thereby enhancing the pressure resistance and shock absorption effect of the internal grating plate of the wet grating ball mill.

[0029] Working principle of the utility model: when in use, grinding balls and fluid medium are put into the wet grid ball mill body 3 through the switch port on the wet grid ball mill body 3, and then the sealing lining plate of the wet grid ball mill body 3 is sealed and tightened. Because the wet grid ball mill body 3 is internally provided with three shock-absorbing grid mesh plates 8 on the left, middle and right for separation, the staff can use the driving motor 4 to drive the reducer 5 to rotate, and the active gear operation on the reducer 5 can control the driven gear 6 to rotate, thereby completing the smooth rotation of the entire wet grid ball mill body 3 on the bearing rotating frame 2. A splash-proof feed pipe 7 is added to the right side of the wet grid ball mill body 3 for the input of materials. The setting of the annular shrink plate 10 can reduce the splash of materials entering the splash-proof feed pipe 7. At the same time, the wet grid ball mill body in the rotating state 3 can drive the spiral guide rod 11 to rotate, guide the movement of materials at the feed port on the wet grid ball mill body 3, and the smooth guide plate 12 is added to assist the materials to smoothly enter the internal main space of the wet grid ball mill body 3. Because the internal grinding balls of the wet grid ball mill body 3 will hit the inner wall lining plate and the shock-absorbing grid mesh plate 8 during the rotation of the wet grid ball mill body 3, in order to ensure the durability of the shock-absorbing grid mesh plate 8, the wear-resistant grid plate body 15 on the shock-absorbing grid mesh plate 8 can be shock-absorbing and buffered by the shock absorber 16 under the impact. Under the guidance of the guide groove 14, the tilting of the wear-resistant grid plate body 15 during the activity is reduced. The sealing protective cover 17 is added to wrap and protect the shock absorber 16, which enhances the splash-proof feeding of the wet grid ball mill and the pressure-resistant and shock-absorbing effect of the internal grid plate.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
