Abstract
The utility model aims at solving the technical problem by providing an outside air sealing ring convenient for detachment and replacement for a grinding roll of an AT0X50 roll type cement raw material vertical mill. The outside air sealing ring is formed by combining a concave sealing element and a convex sealing element, wherein the concave sealing element is in embedded fit with the convex sealing element; bolt holes are respectively formed in the concave sealing element and the concave sealing element in an annular array form; and the concave sealing element and the convex sealing element are respectively formed by folding two semicircular parts. According to the outside air sealing ring disclosed by the utility model, the concave sealing element and the convex sealing element are respectively formed by folding the two semicircular parts; and during detachment and replacement, a grinding roll bearing protecting cover and a fixed screw are required to be dismantled and a joint bearing at the head of a torsion pull bar is not needed to be detached, so that the overhaul and the assembly are facilitated, the service life of the joint bearing at the head of the torsion pull bar is prolonged and the maintenance cost is reduced.
Description
Technical field
The utility model relates to a kind of AT0X50 roll-type cement raw material Vertical Mill, especially the outside air seal ring of T0X50 roll-type cement raw material grinding roller of vertical mill.
Background technique
The outside air seal ring of ATOX50 roll-type cement raw material grinding roller of vertical mill is installed in the shaft of grinding roller socket end and covers; it is inboard to be in the torsional drawbar joint of head bearing that is installed on the shaft of grinding roller; in order to stop dust-containing airflow to enter in the grinding roller bearing, play the effect of protection grinding roller bearing.Existing grinding roller outside air seal ring is combined by spill Sealing and the male seal part of nested cooperation, equal circular array is shown bolt hole on spill Sealing and the male seal part, and spill Sealing and male seal part are fastenedly connected the shaft of grinding roller socket end by high-strength bolt and cover.Because it is inboard that the outside air seal ring is in the torsional drawbar joint of head bearing that is installed on the shaft of grinding roller, therefore, when dismounting and change outside air seal ring, removal torque rod head joint shaft bearing at first, engineering time and difficulty have been increased, reduced the working life of torsional drawbar joint of head bearing, the corresponding maintenance cost that improved.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of AT0X50 roll-type cement raw material grinding roller of vertical mill outside air seal ring of replacing for convenience detach.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of AT0X50 roll-type cement raw material grinding roller of vertical mill outside air seal ring, the spill Sealing and the male seal part that comprise nested cooperation combine, equal circular array is shown bolt hole on spill Sealing and the male seal part, and described spill Sealing and male seal part involute by two-part of semicircular in shape.
Spill Sealing of the present utility model and male seal part involute by two-part of semicircular in shape, when dismounting and change, only need to remove grinding roller joint shaft bearing protective housing and retaining screw, do not need again removal torque rod head joint shaft bearing, maintenance and assembling have been convenient to, prolong the working life of torsional drawbar joint of head bearing, reduced maintenance cost.
Description of drawings
Fig. 1 is the structural representation of male seal part of the present utility model.
Fig. 2 is the sectional view of Fig. 1.
Fig. 3 is the structural representation of spill Sealing of the present utility model.
Fig. 4 is the sectional view of Fig. 3.
Among the figure: 1 male seal part, 2 spill Sealings.
Embodiment
Shown in Fig. 1-4, a kind of AT0X50 roll-type cement raw material grinding roller of vertical mill outside air seal ring, the spill Sealing 2 that comprises nested cooperation combines with male seal part 1, equal circular array is shown bolt hole on spill Sealing and the male seal part, and described spill Sealing and male seal part involute by two-part of semicircular in shape.
In use be convenient to change the aeroseal circle assembly parts of rapid wear, save the repair time, sometimes also can save unnecessary grinding roller joint shaft bearing consumption.
