[0017] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4This patent provides a technical solution: a coal-water slurry mixing device, including a tank 1, a cover 2 installed on the top of the tank 1, a mounting base 3 fixedly installed on the top of the cover 2, a frame 4 integrally formed on the top of the mounting base 3, a motor reducer 5 fixedly installed on the top of the frame 4, a coupling 6 installed at the bottom of the rotating shaft of the motor reducer 5, a mixing shaft 7 connected to the bottom of the rotating shaft of the motor reducer 5 through the coupling 6, a mixing paddle 8 connected to the side wall of the mixing shaft 7 by bolts, and a rotary seal 9 provided on the side wall of the mixing shaft 7;

[0019] The rotary seal 9 includes a rotating ring assembly 10, a mounting ring 12, and a stationary ring 19. The inner wall of the rotating ring assembly 10 is fixedly mounted on the side wall of the stirring shaft 7. The bottom of the rotating ring assembly 10 has a sealing surface 11. The top left and right sides of the mounting ring 12 have mounting holes with bolts inside. The bottom end of the bolts is screwed to the top of the mounting base 3. The top of the mounting ring 12 has an integrally formed circular ring 13. The top left and right ends of the circular ring 13 have threaded grooves, and detachable rings 14 are connected to the threaded grooves by bolts. The top of the mounting ring 12... Both sides of the part are provided with sliding holes 15. A push rod 16 is slidably installed on the inner side wall of the sliding hole 15. A circular plate 17 is integrally formed at the bottom end of the push rod 16. A spring 18 is sleeved on the side wall of the push rod 16. The upper and lower ends of the spring 18 are respectively fixedly installed at the bottom of the mounting ring 12 and the top of the circular plate 17. The top end of the push rod 16 is tightly fitted to the bottom of the stationary ring 19. The top end of the stationary ring 19 is tightly fitted to the sealing surface 11. A pressure ring 20 is integrally formed on the side wall of the stationary ring 19. The top end of the pressure ring 20 is tightly fitted to the bottom of the detachable ring 14.

[0020] Figure 2 The spring 18 shown is in an extended state. Through the rebound effect of the spring 18, the push rod 16 presses the stationary ring 19 upward, thereby pressing the top of the stationary ring 19 onto the sealing surface 11. At the same time, the top of the pressure ring 20 is tightly fitted to the bottom of the detachable ring 14.

[0021] Specifically, a rubber ring 21 is glued to the bottom of the detachable ring 14, and the top of the pressure ring 20 is tightly fitted onto the rubber ring 21.

[0022] The rubber ring 21 is used to enhance the sealing effect between the removable ring 14 and the pressure ring 20.

[0023] Specifically, the top left and right sides of the pressure ring 20 are provided with positioning grooves 22, and the bottom sides of the detachable ring 14 are integrally formed with positioning posts 23. The positioning posts 23 are inserted into the positioning grooves 22, and the side walls of the positioning posts 23 are relatively fitted and slid against the inner side walls of the positioning grooves 22.

[0024] The positioning pin 23 is inserted into the positioning groove 22 to locate the installation position of the stationary ring 19.

[0025] Jinghuan 19 is made of high-temperature resistant graphite plate.

[0026] Specifically, the outer wall of the mounting chassis 3 is integrally formed with a flange 24, which is fixed to the top of the cover 2 by bolts.

[0027] Specifically, the agitator 8 is tilted.

[0028] The impeller is made of wear-resistant materials and coated with wear-resistant alloy materials to ensure long-term use. The impeller shape is designed to reduce resistance, increase drainage volume, and reduce the power consumption of the equipment.

[0029] Working principle: The motor reducer 5 drives the stirring shaft 7 to rotate, which in turn drives the rotating ring assembly 10 to rotate. This causes the sealing surface 11 to rotate on top of the stationary ring 19, achieving a seal and thus sealing the top of the cover 2. When the stationary ring 19 is severely worn, the detachable ring 14 can be removed and moved upwards to detach it from the circular ring 13. Then... Figure 2 As shown, the middle part of the stirring shaft 7 is disconnected. The two sections of the stirring shaft 7 can be connected by a rod (both the upper and lower ends of the rod are connected to the two sections of the stirring shaft 7 by bolts). After removing this rod, the stationary ring 19 can be taken out from between the two sections of the stirring shaft 7 and replaced with a brand new stationary ring 19.
