An efficient conveying device suitable for refractory plastics and castables

Abstract

The invention discloses efficient conveying equipment applicable to a refractory plastic material and castable and belongs to the field of refractory material construction equipment. The efficient conveying equipment is characterized in that the efficient conveying equipment comprises a material mixing device, a feeding device, a material conveying device and a material transferring device. According to the equipment, firstly, pretreatment is conducted on materials needing to be transferred through the material mixing device and the feeding device; and then, the materials are sequentially conveyed to a construction working face of a boiler body of a boiler through the material conveying device and the material transferring device. By means of the material mixing device, firstly, preprocessing is conducted on the castable at site through a material mixing support and a material mixing funnel; then, the materials are transferred transversely through the feeding device, then, material lifting work is performed from bottom to top, and at last, before the aerial conveying link is started to be implemented, differential type high-speed material mixing is conducted through double screws in a feeding barrel in the first place so that the material macromolecule gravity decomposition phenomenon which is possibly generated in the material lifting process can be made up; and finally, the materials are delivered to the aerial work 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 high-efficiency conveying equipment suitable for refractory plastics and castables. Background technique [0002] Coal circulating fluidized bed combustion technology is a new type of coal combustion technology (circulating fluidized bed referred to as CFB) developed in the past two decades, and it is a major innovation to the traditional grate furnace and pulverized coal furnace. [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. The anti-wear measures of CFB are mostly composed of laying thick non-metal refractory bricks, castables and plastics to deal with corrosion and wear d...

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 transportation of non-solid materials during construction, that is, castables and plastics, has always been a difficult point in the industry. The traditional lifting and conveying equipment will precipitate during the transportation process. In addition, the above-mentioned materials need to do a good job of heat dissipation during the transfer process, otherwise the precipitation of large particles will easily cause the solidification of the materials, and eventually cause the equipment to fail to operate normally.
