Description

Technical Field

[0001] This utility model relates to the field of cold slag machines, and in particular to a twin-shaft cold slag feeding screw device. Background Technology

[0002] The slag cooler is an industrial device used in coal-fired boiler systems to process high-temperature slag. It comes in various types, such as drum type, multi-tube type, and membrane type, and is suitable for fluidized bed boilers, three-waste co-firing furnaces, and other scenarios. The slag cooler consists of a cylinder, slag inlet box, and transmission device. It uses a combined air-cooling and water-cooling heat exchange system for cooling, and the cooling water is mostly power plant circulating water to reduce costs.

[0003] When using a slag cooler, it is necessary to process high-temperature slag. The high-temperature slag will heat the internal structural components of the slag cooler. Working under high temperature conditions for a long time will cause the lifespan of the slag cooler to decrease rapidly, which is not conducive to the use of the slag cooler. Utility Model Content

A feeding outlet pipe is fixedly connected to the lower surface of the feeding screw shell, and the unloading flap valve is installed below the feeding outlet pipe.

[0018] By adopting the above technical solution, the crushed material enters from the feed inlet pipe, is conveyed by the screw feed roller, and is discharged from the feed outlet pipe.
