Detailed Description
Referring to fig. 1, a schematic structural diagram of a sliding shoe sealing device of a cement mill is shown; FIG. 2 is a schematic cross-sectional view taken along A-A; fig. 3 is a partial enlarged view of fig. 2 at H.
The application provides a pair of cement mill crawler shoe sealing device, the cement grinding apparatus has barrel 2, the bistrique of barrel 2 all is provided with crawler shoe 1 with the mill tail, the 1 outside of crawler shoe all is provided with crawler shoe cover 3, every the bottom of crawler shoe cover 3 is seted up with the bottom oil sump, barrel 2 all is provided with crawler shoe sealing member 4 with the junction of crawler shoe cover 3 both sides, every the outside of crawler shoe sealing member 4 still is provided with ring seal 5, ring seal 5 one side sets up on barrel 2, and the opposite side sets up on crawler shoe cover 3, ring seal 5 is connected through the welded mode with crawler shoe cover 6, ring seal 5 scribbles high temperature resistant sealed glue with crawler shoe cover 3 welding department, still be connected with at least one time oil pipe 6 on ring seal 5, time oil pipe 6 is connected to the bottom oil sump.
The sliding shoe sealing element 4 is a sealing ring made of high-molecular polyethylene.
Each annular sealing ring 5 is also connected with a plurality of oil return pipes 6. When the lubricating oil leaks out from the original sliding shoe sealing element 4, the lubricating oil is collected into the annular sealing ring 5. The leaked lubricating oil is collected by the oil collecting tank and then returns to a bottom oil bin of the lubricating system through an oil return pipe connected with the oil collecting tank and the sliding shoe oil pool. Therefore, a closed leaked oil recovery closed system of lubrication, leakage, collection and lubrication is formed. The problems of environmental pollution and resource waste caused by leakage of lubricating oil are thoroughly solved.
