Embodiment Construction

[0024] The present invention is further illustrated by the following examples, but not limited to the following examples.

[0025] like figure 1 As shown, the original design structure is that the negative pressure in the vertical mill sucks cold air into the mill. In order to protect the lower bearing 5 of the powder separator, the vertical mill manufacturer designed a vertical shaft shield 4 at the lower bearing 5 of the powder separator to facilitate personnel. Carry out equipment maintenance work in a dust-free state. In the original design, the cold air outside the mill enters the vertical shaft protective cover 4 through the air inlet pipe 6, and then enters the upper pipe of the vertical mill outlet through the air outlet 12 of the protective cover, which plays a role in supplying the bearings. Cooling effect, see the specific process figure 1 shown.

[0026] The present invention improves the position of the bearing cooling air duct. A second air inlet duct 19 is arr...

Abstract

The invention discloses a bearing outer independent air cooling device used under the thermal environment work condition and a cooling operation method. According to the device, a second air inlet pipe is arranged on the left side of the bottom of a vertical shaft protection cover, a bearing second cooling air cover is arranged on the periphery of a bearing, and a bearing cooling independent induced draft fan is arranged on the right side of the bottom of the vertical shaft protection cover and communicates with the bearing second cooling air cover. The bearing cooling independent induced draft fan communicates with the bearing second cooling air cover through an air outlet pipe, the second air inlet pipe and the air outlet pipe are placed on the outer side of a vertical mill, and whethera cooling air pipe is damaged or not can be more conveniently observed and judged. If the bearing outer independent air cooling device is connected with a PLC system, the rotation speed of a draught fan can be automatically controlled through the program, and the cooling air supply volume is flexibly adjusted. The method effectively solves the bottleneck problems that due to the insufficient mainsystem air supply volume, the bearing part is at the high temperature, and the lubricating oil lubricating effect is lowered.

Description

technical field [0001] The invention relates to an external independent air-cooling device for bearings in thermal environment working conditions and a cooling operation method, belonging to the field of mechanical bearing air-cooling. Background technique [0002] The blast furnace slag ultra-fine powder vertical mill production process is in the negative pressure state of the whole system. The original bearing cooling adopts the suction generated by the negative pressure inside the mill to suck the cooling air outside the mill into the bearing of the classifier inside the mill through the connecting pipe on the bearing side. The negative pressure of the entire production system of the vertical mill is generated by the rotation of the main fan of the production line, but in the specific production process, the fan is controlled by frequency conversion, and the speed will be adjusted at any time according to the working conditions on site. If the fan speed is high, the negati...
