Refractory castable conveying equipment capable of achieving efficient heat dissipation and deposition prevention

Abstract

The invention discloses refractory castable conveying equipment capable of achieving efficient heat dissipation and deposition prevention, and belongs to the field of refractory matter construction equipment. The refractory castable conveying equipment is characterized by comprising a mixing device, a feeding device, a conveying device and a transferring device. In the equipment, materials needingto be conveyed are pretreated through the mixing device and the feeding device, and then, the conveying device and the transferring device are used for sequentially conveying the materials to the construction work face of a boiler body. The mixing device conducts pre-machining on castable on the site through a mixing support and a mixing funnel, then, the feeding device is used for transversely transferring the materials, the materials are elevated from bottom to top, and finally in the aerial conveying link, a double helix in a feeding barrel is used for conducting difference type high-speedmixing, accordingly, the phenomenon of material macromolecule gravity decomposition possibly happening in the material elevating process can be offset, and then, the materials are conveyed to the aerial operation construction face through the material conveying device.

Description

technical field [0001] The invention belongs to the field of refractory material construction equipment, and in particular relates to a refractory castable conveying equipment capable of efficiently dissipating heat and preventing precipitation. Background technique [0002] Coal circulating fluidized bed combustion technology is a new type of coal combustion technology developed in the past two decades (circulating fluidized bed referred to as CFB), and it is a major innovation to traditional grate furnaces and pulverized coal furnaces. [0003] In my country, circulating fluidized bed combustion technology has developed rapidly. From the perspective of clean coal combustion, it is also an important starting point for my country to solve environmental protection problems in the near future. CFB is different from traditional pulverized coal boilers. At present, the anti-wear measures of CFB are mostly composed of laying thick non-metal refractory bricks, castables and plasti...

AI Technical Summary

Problems solved by technology

Due to the high height of the entire furnace body of most fluidized bed boilers, the high-altitude conveying of materials during construction has always been a difficult point in the industry. The traditional lifting and conveying equipment will freeze and block during the conveying process, resulting in equipment failure. run
