Description

Background

The roller slag cooler mainly comprises a slag feeding pipe assembly, a slag feeding device, a roller, a rotating system, a driving mechanism, a slag discharging device, a cooling water system, an electric control device and the like. The slag enters the end part of the roller through the slag inlet pipe, the roller rotates to push ash slag to move to the slag outlet end of the roller, the heat of the high-temperature slag is transferred to the inner wall and the blades of the inner barrel through various forms of conduction, convection, radiation and the like and is transferred to the outer wall surface of the inner barrel, then the heat is transferred to cooling medium water in the interlayer of the roller through forced convection heat transfer, and finally the heat of the slag is taken away by the water to achieve the cooling effect.

In the current stage, the roller is supported by two or more groups of carrier roller groups, each group of carrier roller group comprises two carrier roller frames arranged on two sides of the roller in rows and carrier roller pieces arranged in the carrier roller frames, and the carrier roller pieces can rotate along with the rotation of the roller. The carrier roller piece mainly comprises a rotating shaft rotatably connected to the carrier roller frame, a deep groove ball bearing arranged on the outer peripheral wall of the rotating shaft and a supporting ring fixed on the outer periphery of the bearing, wherein the supporting ring is abutted to a supporting ring on the peripheral wall of the roller.

However, in the actual operation process, after the slag cooler operates for a long time, the height of the roller is reduced due to the abrasion of the support ring and the support ring, and the abrasion of a certain group of support ring and the support ring is possibly large, so that the roller is inclined to a certain extent, and the axial force required to be borne by the carrier roller group is increased. In addition, in the operation process, the roller is influenced by the working characteristics of the slag cooler, and the axial movement of the roller is frequent, so that the axial stress of the carrier roller set is easy to break through the limit value.

Because some old-fashioned cylinder slag cooler's bearing is mostly deep groove ball bearing, then its axial atress limit is not high, then when the axial force that the bearing roller group received was too big, the bearing was very easily damaged, stall, leads to the cylinder to rotate the trouble, finally leads to the slag cooler to stop operation.
