[0022] like Figure 1 As shown, the clamping assembly includes a mounting block 7 and a snap-fit ​​block 8. The mounting block 7 is fixedly connected to the top rear side of the mounting frame 4. The top of the mounting block 7 is an arc-shaped structure. The left side of the mounting block 7 is connected to the snap-fit ​​block 8 through a hinge. The bottom of the snap-fit ​​block 8 is an arc-shaped structure. The snap-fit ​​block 8 is engaged with the mounting block 7. The straight pipe of the annular nozzle 6 is located between the mounting block 7 and the snap-fit ​​block 8.

[0023] like Figure 1 , Figure 2 and Figure 5 As shown, the limit assembly includes a guide sleeve 10, a C-shaped clamping rod 11 and an elastic member 12. The guide sleeve 10 is symmetrically fixedly connected to the upper and lower parts of the rear side of the mounting frame 4, and a C-shaped clamping rod 11 is slidably connected between the two guide sleeves 10. The elastic member 12 is fixedly connected between the rear end of the C-shaped clamping rod 11 and the rear side of the guide sleeve 10. The guide plate 3 is symmetrically provided with clamping holes 13, and the lower rear end of the C-shaped clamping rod 11 is slidably matched with the clamping hole 13.

[0025] Initially, the grinding machine barrel 2 is placed horizontally, and the barrel mouth of the grinding machine barrel 2 is closed and facing to the left, the lower rear end of the C-shaped clamping rod 11 is in contact with the clamping hole 13 on the left, the mounting frame 4 is located on the left, and the front part of the annular nozzle 6 is located between the snap-fit ​​block 8 and the mounting block 7. The snap-fit ​​block 8 is snapped with the mounting block 7 through the hook 9, so that the snap-fit ​​block 8 and the mounting block 7 clamp and limit the annular nozzle 6.

[0026] When the water-coal slurry ball mill is needed to be used, the mouth of the grinding machine cylinder 2 is turned vertically upward and opened. After the material is added into the grinding machine cylinder 2, the C-shaped clamping rod 11 is pulled forward, and the elastic member 12 is compressed, so that the lower rear end of the C-shaped clamping rod 11 is out of contact with the clamping hole 13 on the left, thereby releasing the limit on the mounting frame 4, and then the mounting frame 4 is pushed to the right, so that the mounting frame 4 drives the upper part thereof to slide to the right, until the lower rear end of the C-shaped clamping rod 11 is located in front of the clamping hole 13 on the right, and the C-shaped clamping rod 11 is released.

[0027] After the water is added, the external water source is turned off to stop the water outlet at the bottom of the annular nozzle 6 from spraying water, and then the grinding machine cylinder 2 is closed and rotated to reset, and the motor 21 is controlled to work to drive the rotating frame 22 to rotate, so that the rotating frame 22 drives the grinding machine cylinder 2 to rotate, thereby preparing the water-coal slurry. During the processing, according to the needs, water is added to the grinding machine cylinder 2 through the annular nozzle 6 in time to soak it; after the preparation is completed, the motor 21 is controlled to stop working, so that the grinding machine cylinder 2 stops rotating, and then the mounting frame is released by controlling the C-type clamping rod 11. 4, then pull the mounting frame 4 and its upper components to the left to reset, and through the C-shaped clamping rod 11 and the clamping hole 13 on the left, limit the mounting frame 4 and its upper components to the left side of the guide plate 3, then rotate the grinding machine cylinder 2 to vertically upward and open it, and then rotate the rotating frame 22 counterclockwise to facilitate the pouring and collection of the processed water-coal slurry in the grinding machine cylinder 2; after the collection is completed, rotate the rotating frame 22 clockwise to reset, so that the barrel mouth of the grinding machine cylinder 2 is vertically upward, repeat the above steps, and the next batch of water-coal slurry can be prepared.

[0028] When the annular nozzle 6 needs to be replaced, the snap-fit ​​block 8 is rotated to open so that the snap-fit ​​block 8 and the hook 9 are out of contact with the mounting block 7, thereby releasing the clamping of the annular nozzle 6, and then the annular nozzle 6 is taken out from the mounting block 7, and the annular nozzle 6 is separated from the water outlet of the hose 5, and then the new annular nozzle 6 is connected to the water outlet of the hose 5 and put back on the mounting block 7, and then the snap-fit ​​block 8 is rotated to reset so that the snap-fit ​​block 8 and the hook 9 are in contact with the mounting block 7, thereby clamping the annular nozzle 6 for subsequent normal use.
