[0020] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0021] Embodiment: A water-coal slurry ball mill that is easy to clean, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a grinder cylinder 1, a support platform 101, a mounting block 102, a mounting frame 103, a support frame 104, a hydraulic cylinder 4, a mounting ring 5, a connecting frame 6, a connecting shaft 7 and a driving mechanism. The mounting block 102 is fixedly connected to the left side of the top of the support platform 101 symmetrically front and back, and the mounting frame 103 is rotatably connected between the upper parts of the two mounting blocks 102. The upper part of the mounting frame 103 is rotatably connected to the left side of the grinder cylinder 1. The right end of the grinder cylinder 1 is the feed port, and the left end of the grinder cylinder 1 is the discharge port. The mounting ring 5 is rotatably connected to the right side of the grinder cylinder 1. The support frame 104 is fixedly connected to the right part of the top of the support platform 101, and the bottom of the mounting ring 5 is in contact with the top of the support frame 104. The hydraulic cylinder 4 is bolted to the right side of the top of the support platform 101. The connecting shaft 7 is fixedly connected to the telescopic rod of the hydraulic cylinder 4. The upper part of the connecting shaft 7 is slidably connected to the right part of the connecting frame 6, and the left part of the connecting frame 6 is rotatably connected to the mounting ring 5. A driving mechanism is provided on the support platform 101.

[0022] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the driving mechanism includes a sliding rod 2, a sliding rail 8, a motor 3, a transmission assembly and a limit assembly. The sliding rail 8 is fixedly connected to the right front portion of the top of the support platform 101, the sliding rod 2 is slidably connected in the sliding rail 8, the motor 3 is bolted to the top of the sliding rod 2, the motor 3 is connected to the grinding machine cylinder 1 through the transmission assembly, and a limit assembly is provided on the sliding rail 8.

[0023] like Figure 3 As shown, the transmission assembly includes a pinion 31 and a large gear ring 32. The pinion 31 is fixedly connected to the output shaft of the motor 3, and the large gear ring 32 is fixedly connected to the right part of the grinding machine cylinder 1. The pinion 31 meshes with the large gear ring 32.

[0024] like Figure 4 and Figure 5 As shown, the limiting assembly includes an L-shaped plate 9, a wedge-shaped piece 10 and an elastic piece 11. The L-shaped plate 9 is fixedly connected to the upper front side of the slide rail 8. The wedge-shaped piece 10 is composed of a slide rod and a wedge-shaped block. The wedge-shaped block is connected to the rear end of the slide rod. The left side of the wedge block is an inclined surface. The lower part of the L-shaped plate 9 is slidably connected to the slide rod. The wedge block slides through the slide rail 8. The slide rod 2 contacts the inclined surface of the wedge block. An elastic piece 11 is fixedly connected between the wedge block and the L-shaped plate 9, and the elastic piece 11 is wrapped around the slide rod.

[0025] like Figure 3 As shown, a handle 12 is also included. The upper front portion of the sliding rod 2 is fixedly connected to the handle 12, and the handle 12 is an inverted L-shaped structure.

[0026] Initially, the elastic member 11 is in a natural state, the right side of the wedge-shaped member 10 contacts the left side of the sliding rod 2, so that the sliding rod 2 is located on the right side of the slide rail 8, and the small gear 31 and the large gear ring 32 are meshed with each other, thereby limiting the motor 3; when the water-coal slurry ball mill needs to be cleaned, a certain amount of chemical detergent is first injected into the grinding machine cylinder 1, and then the motor 3 is controlled to work to drive the small gear 31 to rotate, and through the meshing action of the small gear 31 and the large gear ring 32, the large gear ring 32 drives the grinding machine cylinder 1 to rotate, so that the grinding machine cylinder 1 is soaked for a certain period of time, the motor 3 is controlled to stop working, so that the grinding machine cylinder 1 stops rotating, and then the wedge-shaped member 10 is pulled forward, and the elastic member 11 is compressed until the wedge-shaped member 10 is out of contact with the sliding rod 2, and then the handle 12 is pushed to the left to make the sliding rod 2 move to the left, thereby driving the motor 3 and the small gear 31 to move to the left until the small gear 31 is out of mesh with the large gear ring 32, and then the wedge-shaped member is released. 10, the elastic member 11 will return to its original state, driving the wedge member 10 to move backward and reset, and then the feed port of the grinder cylinder 1 is connected with the external water pipe, and then the telescopic rod of the hydraulic cylinder 4 is controlled to extend, driving the connecting shaft 7 to move upward, and the connecting shaft 7 slides along the connecting frame 6 and pushes the right side of the connecting frame 6 to move upward, so that the connecting frame 6 rotates counterclockwise to a certain extent, driving the mounting ring 5 to move upward and disengage from the support frame 104, and the mounting ring 5 drives the right side of the grinder cylinder 1 to move upward, so that the grinder cylinder 1 drives the mounting frame 103 to rotate counterclockwise on the mounting block 102 until the grinder cylinder 1 rotates to a tilted state, and then rinses the inner wall of the grinder cylinder 1 with water, so that the residue slides down along the inner wall of the grinder cylinder 1 and is discharged through the discharge port of the grinder cylinder 1, so that the residue and water in the grinder cylinder 1 are easily discharged to the outside, which can reduce material residue, have a good cleaning effect, and are easy to operate, saving time and effort, and improving work efficiency.

[0027] After cleaning, the telescopic rod of the hydraulic cylinder 4 is shortened by controlling the connecting shaft 7 to drive the connecting frame 6 and its upper parts to move downward and reset, and the mounting ring 5 drives the grinding machine cylinder 1 to rotate clockwise until the bottom of the mounting ring 5 contacts the top of the support frame 104, thereby completing the horizontal reset of the grinding machine cylinder 1, and then pulling the handle 12 to the right to make the sliding rod 2 slide to the right along the slide rail 8. When the sliding rod 2 contacts the inclined surface of the wedge 10, the wedge 10 is squeezed to move forward and the elastic member 11 is compressed. When the sliding rod 2 is out of contact with the inclined surface of the wedge 10, under the elastic force of the elastic member 11, the wedge 10 is driven to move backward and reset until the right side of the wedge 10 contacts the left side of the sliding rod 2. At this time, the wedge 10 limits the sliding rod 2 again, and the small gear 31 and the large gear ring 32 engage with each other, thereby completing the limiting of the motor 3, which is convenient for subsequent normal use.

[0028] like Figure 2As shown, it also includes a limiting ring 13 and a locking rod 14. The limiting ring 13 is fixedly connected to the bottom of the mounting frame 103. The limiting ring 13 is a hollow rod structure connected front and back. A locking rod 14 is slidably connected between the lower parts of the two mounting blocks 102, and the locking rod 14 slidably cooperates with the limiting ring 13. Initially, the rear end of the locking rod 14 is inserted into the front mounting block 102, the limiting ring 13 and the rear mounting block 102 in sequence, thereby limiting the mounting frame 103. When it is necessary to tilt the grinding machine cylinder 1, first pull the locking rod 14 forward to make the locking rod 14 and the front mounting block 102 close to each other. The block 102, the limiting ring 13 and the mounting block 102 on the rear side are disengaged, thereby releasing the limit on the mounting frame 103, and then controlling the hydraulic cylinder 4 to work; when the grinding machine cylinder 1 is reset to the horizontal position, the locking rod 14 is inserted backward and reset, so that the locking rod 14 contacts with the mounting block 102 on the front side, the limiting ring 13 and the mounting block 102 on the rear side, thereby limiting the mounting frame 103. In this way, the horizontal state of the grinding machine cylinder 1 can be ensured, and the subsequent work of the grinding machine cylinder 1 can be affected by misoperation, thereby ensuring the subsequent use effect and improving the safety of use.

[0029] like Figure 6 As shown, it also includes a drain cover 15 and a locking ring 16. The drain cover 15 is rotatably connected to the left front side of the grinder cylinder 1, and the locking ring 16 is fixedly connected to the left front side of the grinder cylinder 1. The locking ring 16 is located below the drain cover 15, and the drain cover 15 is engaged with the locking ring 16; when cleaning is completed, the drain cover 15 is limited by the locking ring 16 and the drain cover 15 is rotated to open, so that the bottom of the grinder cylinder 1 can be further cleaned, thereby ensuring the cleaning effect of the residue in the grinder cylinder 1; after cleaning, the drain cover 15 is rotated to close, and the drain cover 15 is limited by the locking ring 16, which can ensure the subsequent use effect of the grinder cylinder 1 and is convenient to use.
