Cooling device of slag cooler

Abstract

The invention discloses a cooling device of a slag cooler. The cooling device comprises a liquid-inlet pipe base, a liquid-return pipe base, a bearing block, a central liquid-inlet pipe and a rotary liquid-return pipe, wherein a liquid inlet is formed in the liquid-inlet pipe base; a liquid-return opening and a liquid-return through hole are formed in the liquid-return pipe base; an inner hole is formed in the bearing block; the rotary liquid-return pipe is rotationally arranged in the inner hole of the beating block through a bearing; the central liquid-inlet pipe is arranged in the rotary liquid-return pipe; the upstream end of the central liquid-inlet pipe is communicated with the liquid inlet; the inner hole of the rotary liquid-return pipe and the outer wall of the central liquid-inlet pipe form a liquid-return passage; the liquid-return passage is communicated with the liquid-return through hole and the liquid-return opening; the downstream end of the central liquid-inlet pipe penetrates through a central shaft of the slag cooler; the rotary liquid-return pipe is fixedly connected with the central shaft; a liquid-return shaft hole of the central shaft is communicated with the liquid-return passage. According to the cooling device, cooling liquid can be effectively guaranteed to circularly flow in the slag cooler, the sealing property is guaranteed, maintenance is convenient to perform, and the cooling effect is improved.

Description

technical field [0001] The invention relates to a cooling device, in particular to a cooling device of a slag cooler. Background technique [0002] The current slag cooling machine generally includes a bracket and a drum. The drum is provided with a driving roller and at least two driven rollers. The bracket is provided with a supporting wheel, and the roller is rotatably connected to the supporting wheel. The bracket is provided with a base. The base is provided with a motor connected to the drive roller ring, the upstream end of the drum is provided with a feed pipe, the downstream end of the drum is provided with a discharge pipe, the drum is provided with a spiral piece along the axial direction, and the downstream end of the drum is provided with a feed pipe along the center line of the drum. The central shaft extending to the upstream end of the drum to the left, the part of the central shaft in the drum is fixedly connected with the spiral piece, the central shaft is ...

AI Technical Summary

Problems solved by technology

One end of the central shaft is connected to the liquid inlet pipe, and the other end is connected to the liquid outlet pipe. The cooling path is short and the cooling effect is poor. At the same time, the central shaft rotates with the drum, and it is difficult to ensure the sealing at the connection. At the same time, the high-speed rotating bearing of the central shaft is easy to wear, and the central shaft Axial movement is prone to occur, affecting sealing performance
