Description

Technical Field

[0001] This utility model relates to the field of ball mills, and specifically to a ball mill with a start-up auxiliary device. Background Technology

[0002] The production of quartz stone slabs requires grinding crushed quartz stone raw materials to a fineness of 150-325 mesh. The equipment often used in this process is a ball mill. The ball mill consists of a base, a cylinder assembly, and a drive mechanism. The drive mechanism is often an electric motor. When the ball mill starts, the resistance of the rotating cylinder assembly is relatively large, which causes the electric motor to be overloaded. During startup, excessive current or even tripping may occur, leading to the failure of the ball mill to start. Summary of the Invention

[0003] The purpose of this invention is to provide a ball mill with a starting auxiliary device, which has the advantages of reducing starting current and reducing starting tripping.

[0004] The technical solution adopted is as follows:

[0005] A ball mill with a starting auxiliary device includes a ball mill base, a bearing seat assembly at the upper end of the ball mill base, a cylindrical assembly rotatably mounted on the bearing seat assembly, a driven gear ring coaxially mounted on the outer side of the cylindrical assembly, a main power motor, an auxiliary starting motor, and a primary drive shaft mounted on the ball mill base, the two ends of the primary drive shaft being connected to the main power motor and a clutch respectively, the auxiliary starting motor being connected to the clutch, a secondary drive shaft rotatably mounted on the ball mill base and parallel to the primary drive shaft, both the secondary drive shaft and the primary drive shaft being equipped with drive gears and the two drive gears meshing, the secondary drive shaft being equipped with a drive gear meshing with the driven gear ring.

[0006] Preferably, the clutch is an electric clutch.

[0007] Preferably, the ball mill base is provided with a protective cover that covers the passive gear ring.

[0008] Compared to existing technologies, the advantages are:

[0009] When starting the cylinder assembly, the main power motor and the auxiliary starter motor jointly drive the primary transmission shaft to rotate. The power is transmitted to the cylinder assembly by the meshing of two transmission gears between the secondary transmission shaft and the primary transmission shaft. Compared with using only the main power motor, using the auxiliary starter motor to drive together reduces the starting current and reduces the problem of starting tripping. After the cylinder assembly is successfully started and running stably, the power of the auxiliary starter motor is disconnected by the clutch, and then the auxiliary starter motor is turned off.

[0014] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:

[0015] Example 1: A ball mill with a start-up auxiliary device, comprising a ball mill base 1, a bearing seat assembly 2 provided at the upper end of the ball mill base 1, a cylindrical assembly 3 rotatably provided on the bearing seat assembly 2, the cylindrical assembly 3 rotating on the bearing seat assembly 2, a discharge hopper assembly 4 provided at one end of the bearing seat assembly 2, the discharge hopper assembly 4 being used to discharge the ground material inside the cylindrical assembly 3, and a driven gear ring coaxially provided on the outer side of the cylindrical assembly 3.

[0016] The ball mill base 1 is equipped with a main power motor 6, an auxiliary starter motor 7, a primary drive shaft 8, and a clutch 10. The primary drive shaft 8 is horizontally rotatably mounted on the upper end of the ball mill base 1. The two ends of the primary drive shaft 8 are connected to the main power motor 6 and the clutch 10, respectively. The secondary drive shaft 9 is equipped with two drive gears on both the primary drive shaft 8 and the secondary drive shaft 9. The secondary drive shaft 9 is equipped with a drive gear that meshes with the driven gear ring.

[0017] Example 2: A ball mill with a start-up auxiliary device includes a ball mill base 1, a bearing seat assembly 2 is provided at the upper end of the ball mill base 1, a cylindrical assembly 3 is rotatably provided on the bearing seat assembly 2, the cylindrical assembly 3 rotates on the bearing seat assembly 2, a discharge hopper assembly 4 is provided at one end of the bearing seat assembly 2, the discharge hopper assembly 4 is used to discharge the ground material in the cylindrical assembly 3, a driven gear ring is coaxially provided on the outer side of the cylindrical assembly 3, and a protective cover 5 is provided on the ball mill base 1 covering the driven gear ring.

[0018] The ball mill base 1 is equipped with a main power motor 6, an auxiliary starter motor 7, a primary drive shaft 8, and a clutch 10. The primary drive shaft 8 is horizontally rotatably mounted on the upper end of the ball mill base 1. The two ends of the primary drive shaft 8 are connected to the main power motor 6 and the clutch 10, respectively. The clutch 10 is an electric clutch 10. The secondary drive shaft 9 and the primary drive shaft 8 are both equipped with two drive gears. The secondary drive shaft 9 is equipped with a drive gear that meshes with the driven gear ring.

[0019] The working principle is as follows:

[0020] When starting the cylinder assembly 3, the main power motor 6 and the auxiliary starter motor 7 jointly drive the primary transmission shaft 8 to rotate. By utilizing the meshing of two transmission gears between the secondary transmission shaft 9 and the primary transmission shaft 8, power is transmitted to the cylinder assembly 3. Compared to using only the main power motor 6, using the auxiliary starter motor 7 to jointly drive reduces the starting current and reduces the problem of starting tripping. After the cylinder assembly 3 starts successfully and runs stably, the power of the auxiliary starter motor 7 is disconnected by the clutch 10, and then the auxiliary starter motor 7 is turned off.
