Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel belt crushing, in particular to a cleaning device for a steel belt crusher bearing seal and a steel belt crusher. Background Art
[0002] like Figure 1~2 As shown, currently, the known crusher consists of a crushing frame 1, a crushing shaft 2, a bearing support unit 3, a bearing 4, a shaft seal 5, a motor 6 and a coupling 7. The motor 6 drives the crushing shaft 2 to perform shearing, rolling or other crushing actions in the crushing box.
[0003] Traditional crushers generate a lot of dust when crushing materials. In order to prevent dust from entering the bearing unit, dust-proof measures such as soft or hard shaft seals, O-rings, wool felt, etc. are designed and adopted. Figure 1~2 The hard shaft seal is shown in the figure. With the use, the shaft seal 5 and the crushing shaft 2 will continue to wear and a certain gap will appear. At this time, the seal will fail and a new shaft seal 5 needs to be replaced. If the shaft seal 5 is not replaced in time, dust will enter the gap between the bearing 4 and the shaft seal 5, and then enter the bearing 4. As the dust continues to accumulate and compress, the rotation resistance of the crushing shaft 2 will increase, the motor 6 will operate overloaded, and the power consumption will increase. At the same time, when the shaft runs at high speed, part of the dust will melt due to friction and heat. This part of the melted dust can easily enter the bearing 4, causing the bearing 4 to fail in lubrication and greatly shortening the service life of the bearing 4. Due to structural limitations, this situation is often not discovered in time during use. In addition, replacing the sealing components requires a lot of manpower, and the production efficiency is further affected when the machine is shut down for maintenance. Summary of the invention
