Description

Technical Field

[0001] The utility model relates to a vertical mill separator bearing temperature measuring device, belonging to the technical field of separator bearing temperature measurement. Background Art

[0002] The vertical mill integrates drying, grinding and powder selection, which simplifies the process of preparing powdered materials. Compared with the preparation of powdered materials by ball mill, it has the advantages of less land occupation, less investment, low power consumption and low noise. It has obvious energy-saving and emission-reduction effects and is widely used in cement, electricity, metallurgy, non-metallic minerals and other industries. As we all know, fineness, that is, the aggregate particle size of the ground product, is an important indicator of the ground product. The fineness of the vertical mill grinding product is controlled by the separator located at the top of the vertical mill; the vertical mill separator is generally composed of a shell, a transmission device, a rotor, fixed blades, an air outlet and a hopper. The fixed blades are fixed on the shell, and the rotor is in the ring composed of the fixed blades and is driven to rotate by the transmission device. After being ground by the vertical grinding device, the material is dispersed in the air flow to form a dusty air flow under the suction force of the system fan, and flows upward and enters from the lower part of the separator; the dusty air flow entering the separator first passes through the fixed blades to change its direction, and the coarse particles in the dusty air flow are separated due to stall and fall into the hopper, and the air flow then enters the rotor. The larger particles are further separated by the centrifugal force of the rotor, and the fine powder passing through the rotor enters the air outlet with the air flow, and is finally captured by the dust collector in the system to become a grinding product.

[0003] In the prior art, for example, the "Special separator for inner and outer rings of bearings" with Chinese patent number CN 206029761 U includes a separator and a fixed seat. The separator includes a screw and a crossbeam for screw positioning. The top of the screw is provided with a nut and the bottom is provided with a tip.

The bearing outer ring placement hole at the lower end of the fixed seat is provided with a shaft neck fixing groove and a bearing inner ring fixing groove. The bearing outer ring placement holes at the upper and lower ends are connected through the shaft neck inner hole. Its beneficial effects are simple structure, convenient operation, and the ability to quickly separate the shaft neck from the bearing; when there is only the bearing inner ring, the bearing inner ring can also be easily separated from the shaft neck; it can not only achieve rapid separation of the shaft and the bearing, but also ensure that the shaft neck is not damaged.

[0004] However, in the prior art, in order for the vertical mill separator bearing temperature measuring device to achieve long-term stable operation, a prerequisite is to have a well-installed and stable support frame. Generally, the support frame is complicated to install and has poor stability. Therefore, a vertical mill separator bearing temperature measuring device is designed. Utility Model Content
