Description
Technical Field
[0001] The utility model relates to the technical field of ball mill equipment, in particular to a cooling jacket for a bearing seat of a vibration ball mill. Background Art
[0002] During the production process, the temperature of the ball mill transmission shaft bearing body is easy to exceed the set temperature of 60℃. Especially when the bearing is lubricated with grease, it is difficult to cool down, the bearing life is short, and it is easy to cause damage to related parts, equipment failure and safety accidents; the maintenance cost is high and the labor intensity is high. In the existing water-cooled bearing seat, it is often recast or the structure of the original bearing seat must be destroyed, and the original bearing seat must be disassembled from the equipment for processing, which is not conducive to the transformation and upgrading of existing production equipment, and the cost is high and the cycle is long.
[0003] In order to solve the deficiencies of the above-mentioned prior art, it was found through search that the authorization announcement number CN203348352U discloses a double-barrel vibrating ball mill bearing positioning cooling device, including an end cover, a sealing ring, a pressure plate, a main shaft, a cooling water tank, a cooling water inlet joint, a bearing, a sealing ring fastening bolt, an end cover fastening bolt, a bearing jacket, a refueling pipe, a cooling water outlet joint, a cooling water jacket and a positioning ring, characterized in that a plurality of bearings are arranged between the main shaft and the bearing jacket, a positioning ring is arranged on the middle outer periphery of the bearing, end covers and pressure plates are arranged at both ends of the main shaft, the outer side surface of the end cover is connected to the pressure plate through a sealing ring fastening bolt, the sealing ring is connected to the outer side surface of the pressure plate through a sealing ring fastening bolt, the inner side surface of the end of the end cover is connected to the bearing jacket through the end cover fastening bolt, the outer periphery of the bearing jacket is a cooling water jacket, a cooling water tank is arranged between the bearing jacket and the cooling water jacket, the upper and lower parts of the cooling water tank are respectively connected to the cooling water outlet joint and the cooling water inlet joint, the refueling pipe runs through the cooling water jacket and the bearing jacket, and the bottom end of the refueling pipe is located at the bearing.
[0004] Although this solution makes it easy to disassemble and assemble the bearings and sealing rings, accurately position them, and maximize the service life of the bearings, there are still some shortcomings: the bearing outer jacket and the cooling water jacket are separately set. Although the bearing outer jacket is integrated and there is no weld on the inner diameter, the cooling water cannot enter the bearing, but the cooling water jacket is very likely to slip and be damaged during the operation of the ball mill, and safety cannot be guaranteed.

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.
[0023] See also Figures 1 to 5 , the utility model provides a technical solution:
[0024] A vibration ball mill bearing seat cooling jacket comprises a frame 1, a ball mill barrel 2, a flipping mechanism 3 and a vibration mechanism 4, wherein a motor base plate 5 is fixedly mounted on the upper surface of the frame 1, a main motor 6 is mounted on the motor base plate 5, a driving end of the main motor 6 is connected to a first universal telescopic coupling 7, a protective cover shell 8 is mounted above the first universal telescopic coupling 7, the other end of the first universal telescopic coupling 7 is connected to a vibration mechanism 4, the vibration mechanism 4 is used to drive the ball mill barrel 2 to vibrate, a flipping motor 9 is mounted on the upper surface of the frame 1, a driving end of the flipping motor 9 is connected to a second universal telescopic coupling 10, the second universal telescopic coupling 10 is connected to the flipping mechanism 3, the flipping mechanism 3 is used to flip the position of the ball mill barrel 2, and the bearing seat jacket 16 is arranged inside the vibration mechanism 4 to reduce the temperature of the bearing 15.
[0025] Specifically, the vibration mechanism 4 includes an eccentric crankshaft 13, a vibrator housing 14 and a bearing 15. One end of the eccentric crankshaft 13 is bolted to the first universal telescopic coupling 7. The vibrator housing 14 is sleeved on both ends of the eccentric crankshaft 13. The bearing 15 is fixedly sleeved on the eccentric crankshaft 13 through a round nut 17. The bearing seat jacket 16 is installed outside the bearing 15. The bearing seat jacket 16 is fixedly sleeved with the eccentric crankshaft 13 through a first sealing ring 18. The lower end of the bearing seat jacket 16 is welded with a cooling medium inlet pipe 19, the upper end is welded with a cooling medium outlet pipe 20, and a bearing seat pressure cover 21. The bearing The seat pressure cover 21 is clamped on one side of the bearing seat jacket 16 and connected to the vibrator housing 14, and is fixedly sleeved with the eccentric crankshaft 13 through the second sealing ring 22. When the ball mill is running, the main motor 6 drives the eccentric crankshaft 13 to rotate rapidly, and the bearing 15 will generate a large amount of heat, which will be transferred to the bearing seat jacket 16. The cooling medium (air, nitrogen, carbon dioxide, cooling water, etc.) is introduced from the cooling medium inlet pipe 19 installed at the lower end of the bearing seat jacket 16 into the bearing seat jacket 16 to absorb the heat on the bearing, and then the cooling medium is discharged from the outlet pipe 20 at the upper end, thereby achieving the purpose of reducing the temperature of the bearing 15 and protecting the equipment.
[0026] Specifically, an eccentric disk 23 and an eccentric mass 24 are provided inside the vibrator housing 14. The eccentric disk 23 is fixedly sleeved on the end of the eccentric crankshaft 13, and the eccentric mass 24 is fixedly installed on the periphery of the eccentric disk 23. Through the combined use of the eccentric disk 23 and the eccentric mass 24, the eccentric crankshaft 13 generates periodic torque and centrifugal force when rotating, thereby causing the ball mill to vibrate. This vibration can promote better mixing and collision of the grinding balls and materials, thereby improving the grinding efficiency of the materials. According to different materials, the eccentric weight of the equipment can also be adjusted by the eccentric mass 24.
[0027] Specifically, the flipping mechanism 3 includes a large gear 25, a small gear 26 and a main shaft 27. The small gear 26 is bolted to the second universal telescopic coupling 10, the small gear 26 is meshed and clamped with the large gear 25, and the large gear 25 is fixedly connected to the main shaft 27. The small gear 26, the large gear 25 and the main shaft 27 are driven by the flipping motor 9 to rotate accordingly, thereby driving the ball mill barrel 2 to flip over, and then pour out the ground material in the barrel, and then return the barrel body to the normal state after the discharge is completed.
[0028] Specifically, the ball mill barrel body 2 passes through the main shaft 27 and is fixedly connected to the main shaft 27. An upper cover mesh plate 28 is arranged on the top of the ball mill barrel body 2, and an upper cover 29 is installed above the upper cover mesh plate 28. Barrel body support seats 30 are arranged on both sides of the ball mill barrel body 2. The lower end of the barrel body support seat 30 is connected to a spring support seat 11, and the spring support seat 11 is connected to one end of the spring 12, and the other end of the spring 12 is connected to the spring support seat 11 arranged on the upper surface of the frame 1. The spring 12 and the spring support seat 11 connected at the lower end of the barrel body support seat 30 can reduce the direct friction between the ball mill barrel body 2 and the frame 1, reduce wear, and extend the service life of the equipment.
[0029] Specifically, both ends of the barrel support seat 30 are provided with fixing blocks 31, and support rods 32 are installed between the fixing blocks 31. The support rods 32 can transmit the vibration energy to the entire ball mill barrel 2 through the connection with the barrel support seat 30, so that the ball mill barrel 2 remains stable during the vibration process, avoiding distortion or deformation caused by vibration. The support rods 32 can also disperse the stress on the ball mill barrel 2 and reduce the risk of local damage caused by stress concentration. The support rods 32 can also play a certain shock-absorbing role, reduce the impact of vibration on other components and vibration noise, and improve the service life and operation stability of the equipment.
[0030] The working principle of this embodiment is as follows: when in use, the main motor 6 is started, and the main motor 6 drives the eccentric crankshaft 13 to rotate, and the eccentric block 24 and the eccentric disk 25 rotate at high speed, driving the vibration of the ball mill barrel 2, and the grinding balls inside the ball mill barrel 2 vibrate and impact the material, so that the material is ground. When the eccentric crankshaft 13 is running, the bearing 15 will generate a large amount of heat, which will be transferred to the bearing seat jacket 16. The cooling medium (air, nitrogen, carbon dioxide, cooling water, etc.) is introduced into the inlet pipe 19 at the lower end of the bearing seat jacket 16. After entering the bearing seat jacket 16 to absorb the heat on the bearing 15, the cooling medium is discharged from the outlet pipe 20 at the upper end to achieve forced cooling, so that the bearing 15 can run for a long time and the vibrating ball mill can work continuously. After the grinding is finished, the turning motor 9 is started to drive the small gear 26, the large gear 25 and the main shaft 27 to rotate accordingly, thereby driving the ball mill barrel 2 to turn over, and then pour out the ground material, and then return to the barrel after the discharge is completed.
[0031] The remaining parts not described in this utility model are existing or known technologies.
[0032] 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.
