Description

Technical Field

[0001] This utility model relates to the field of air jet mill technology, and more specifically, to a dedicated power output device for an air jet mill analyzer. Background Technology

[0002] An air jet mill is a commonly used ultrafine grinding equipment that uses a high-speed airflow (such as compressed air or superheated steam) to pulverize material particles through collision and friction. The pulverized material is then conveyed to an analyzer. The analyzer classifies the material, collecting the qualified particle size and returning the unqualified material (usually oversized particles) to the air jet mill for further pulverization. This ensures that the final product meets the particle size requirements.

[0003] Because air jet mills operate at high speeds, the transmission components in their power output devices are prone to wear and tear, requiring regular maintenance and replacement. However, existing power output devices are enclosed structures, with the motor and transmission components sealed and fixed inside the motor housing, making maintenance and replacement complicated. Therefore, it is necessary to solve this problem. Utility Model Content

[0008] The output shaft extends vertically through the motor housing, with its lower end connected to the output end of the motor and its upper end passing through the connecting seat and connected to the rotating components inside the air jet mill.

[0009] A first bearing housing is fixedly placed at the upper end of the motor housing, and a first bearing fitted onto the output shaft is disposed inside the first bearing housing.

[0010] The second bearing housing is fixedly placed at the lower end of the motor housing, and a second bearing is installed inside the second bearing housing and mounted on the output shaft.

[0011] The beneficial effects of this utility model are: the first bearing housing and the first bearing are located at the upper end of the motor housing, and the second bearing housing and the second bearing are located at the lower end of the motor housing, which ensures stable operation of the output shaft, facilitates bearing replacement or maintenance, eliminates the need to disassemble the motor housing, and improves convenience.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the motor housing has multiple windows on its side wall, and these windows are arranged at equal intervals along the side wall of the motor housing.

[0014] The advantages of adopting the above-mentioned further solution are: the use of multiple windows facilitates the observation of the operation and status of the first bearing housing and the first bearing, improving convenience; it also facilitates the replacement and maintenance of other components inside the motor housing.

[0015] Furthermore, a speed measuring ring is fixedly mounted on the output shaft, and the speed measuring ring is located inside the motor housing.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the speed measuring ring measures the speed of the output shaft, which makes it easier for operators to understand the speed of the output shaft in real time, thereby understanding the operating status of the airflow mill analyzer in real time.
