Description

Technical Field

[0001] The utility model relates to the technical field of ball mill equipment, in particular to a tiltable power post-mounted wet mill. Background Art

[0002] A ball mill is a device that can grind and crush materials. It is most common in the production industries of building materials, fertilizers, mineral processing, glass and ceramics. Ball mills can be divided into two types: dry and wet according to different processes. Among them, wet ball mills are mainly used in the processing of cemented carbide raw materials. The transmission process of the wet mill that is most widely used on the market is: a three-phase asynchronous motor is used to drive the reducer, and then the driving wheel of the reducer is driven to the driven wheel of the drum through a chain. This transmission method has high requirements for the tension of the chain, which should not be too loose or too tight, and it is necessary to ensure that the driving and driven wheels are always on the same transmission line, which requires the operator to frequently inspect the sprocket assembly; at the same time, this structure also has restrictions on the transmission speed. After long-term operation, the pitch of the chain will increase and cause it to fall off, greatly increasing the installation and maintenance costs of the equipment. In addition, most wet grinders on the market currently use direct-drive motors to increase efficiency and reduce emissions. However, these motors are bulky and difficult to achieve explosion-proof performance. When the rear-mounted body causes the center of gravity to move backward, the difficulty of supporting and locking them also increases dramatically, which is not conducive to the stable operation of the equipment. In summary, a new type of wet grinder is needed to solve the above problems. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a tiltable power rear-mounted wet grinder, comprising a frame, one end of the frame is hinged to the front bearing seat of a swing frame, the other end of the frame is provided with a receiving device that fits with the swing frame, the receiving device can limit the swing frame, the rear bearing seat of the swing frame is provided with a driving assembly, the two bearing seats are rotatably connected to a grinding barrel assembly, the hollow rotating shaft of the barrel in the grinding barrel assembly is driven to rotate by the driving assembly, and the bottom of the swing frame is connected to the output end of the oil cylinder in the flip mechanism.

[0004] Furthermore, the grinding barrel assembly includes a barrel cover, which cooperates with the barrel mouth at the barrel neck of the barrel.

The head end of the hollow rotating shaft is connected to the water jacket on the inner wall of the barrel, and the tail end of the hollow rotating shaft is connected to the external cooling water pipeline through a rotating joint.

[0005] Furthermore, the drive assembly includes a drive motor, which is mounted on a reduction gear box connected to the center of the rear bearing seat.
