Embodiment Construction

[0045] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0046] Such as Figure 8 As shown, a fast conveying equipment for anti-solidification refractory castables includes four parts: a mixing device, a feeding device, a conveying device and a feeding device. The four parts work together to complete the material delivery work.

[0047] Such as Figure 9 As shown, the mixing device includes a mixing bracket and a mixing funnel. The upper opening of the mixing funnel is a premixing inlet, and the material enters the mixing equipment from the mixing inlet. The lower opening of the mixing funnel is a premixing inlet. The material outlet, after the material mixing is completed, enters the next working link. The mixing funnel is installed on the mixing bracket, and a mixing power device is installed in the mixing funnel. The mixing power device is connected to the spiral mixing rotor and can ...

Abstract

The invention provides fast conveying equipment for solidification-resisting type refractory castable and belongs to the field of refractory material construction equipment. The equipment is characterized by comprising a material mixing device, a feeding device, a material conveying device and a material transferring device. According to the equipment, at first, the material mixing device and thefeeding device carry out pretreatment on materials needing to be conveyed, and then the material conveying device and the material transferring device sequentially convey the materials to the construction operation face of a boiler body. The material mixing device carries out pre-machining on the castable on site firstly through a material mixing support and a material mixing hopper, then the feeding device transfers the materials transversely and then carries out material lifting operation from bottom to top, when the high-altitude conveying link is carried out finally, at first, double helixes in a feeding cylinder carry out gap type high-speed material mixing, thus, the phenomenon of material macromolecule gravity decomposition possibly generated in the material lifting process is avoided, and finally the materials are conveyed to the high-altitude 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 fast conveying equipment for anti-solidification type refractory castables. 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 plastics to deal with corrosion and wear d...
