Description

Technical Field

[0001] The utility model belongs to the technical field of coal powder separators, and in particular relates to a remote oiling device for a bearing chamber of a dynamic coal powder separator. Background Art

[0002] Traditional coal mill coal powder separators generally use radial static separators, but when the type of coal used changes continuously, it is difficult for the static separator to adjust the fineness of the coal powder, and the uniformity of the coal powder is poor. Therefore, through research and development and transformation, the traditional static separator has been changed to Figure 1 The dynamic coal powder separator shown, the dynamic separator 11 can realize dynamic adjustment of coal powder adsorption within a certain range, meeting the requirements of the coal powder machine for coal powder fineness.

[0003] The dynamic coal powder separator needs to regularly add molybdenum disulfide lithium-based grease to the bearing chamber 12 through the oil nozzle at the lower end of the motor bearing seat to lubricate the bearing and improve the high temperature resistance of the upper and lower bearings in the bearing seat device. When refueling, due to the low and narrow working space, the operator often needs to squat on the coal powder separator shell to refuel, and each operation takes about 15 minutes. However, during the daily operation of the coal powder separator, the internal temperature of the coal powder separator is generally maintained above 110°, and the surface temperature of the coal powder separator shell is also around 60°. The narrow working space during refueling brings inconvenience to the operators and creates a safety hazard that the operators are easily scalded. Utility Model Content

[0024] The lubricating grease storage tank 1 is connected to the connecting pipe 3 via a filter element 8, so that the lubricating grease is filtered and impurities with larger particles therein can be removed.

[0025] In order to more accurately control the amount of oil added, the lubricating grease storage tank 1 is designed to be an elongated cylinder. The body of the lubricating grease storage tank 1 is made of transparent glass. A scale ruler 9 is provided on the lubricating grease storage tank 1 .

[0026] A vent hole is provided at one side of the bottom of the lubricating grease storage tank 1, and a vent plug 10 is provided on the vent hole. Deflating through the vent plug can reduce the extrusion resistance.

[0027] Implementation principle: When in use, rotate and open the gland 6 on the top of the grease tank 1, take out the driving part together with the piston 4 upwards, and then inject grease into the container; then rotate the crank 7 to move the piston 4 to the upper limit position, reinstall the piston 4 together with the driving part onto the grease tank 1, and tighten the gland 6. Then rotate the crank 7 clockwise to drive the screw 5 and the piston 4 to squeeze the grease downward, so that the grease flows into the bearing chamber 12 of the separator along the connecting pipe 3 after being filtered, and the refueling is completed.
