Embodiment Construction

[0012] Ultra-high water materials refer to hydraulic materials with a water volume ratio of up to 95-97% (water-cement ratio about 6.5:1-11:1). The main material of the material consists of two main materials A and B and two auxiliary materials A-A and B-B, a total of 4 components. When the ultra-high water filling material is used, A and A-A materials, B and B-B materials are mixed with water to form A slurry and B slurry, which are transported independently through pipelines, mixed near the filling site, and then transported to the use site. After the ultra-high water material A and B slurries are fully mixed, they can be consolidated in a short period of time (10-90min) to form a consolidated body mainly composed of ettringite.

[0013] The main purpose of the present invention is to add solid waste to the greatest extent when using ultra-high water materials to fill gobs, make full use of waste, reduce the usage of ultra-high water materials to reduce filling costs.

Abstract

The invention relates to an ultrahigh water material composite solid waste pulping, delivering and mixing device. The device comprises a solid waste material pulping device, an ultrahigh water material A pulping device and an ultrahigh water material B pulping device, wherein the solid waste material pulping device has the structure that the lower end of a solid waste material cabin is provided with a solid waste material scale, the lower end of the solid waste material scale is provided with a feed end of a solid waste feeder, a discharge end of the solid waste feeder is arranged at the upper end of a solid waste mixing cabin, the lower end of the solid waste mixing cabin is communicated with a solid waste stirring barrel, the lower end of the solid waste stirring barrel is communicated with a mixing device through a first pipeline and a first high-capacity pump, and the solid waste stirring barrel is communicated with a water injection pipe through a first flow meter; the ultrahigh water material A pulping device and the ultrahigh water material B pulping device have structures similar to the solid waste material pulping device. The device has high degree of automation, is convenient to operate and low in use cost and can realize long-distance transportation.

Description

technical field [0001] The invention relates to a pulping, conveying and mixing device for compounding high-water materials and solid waste. Background technique [0002] With the rapid development of my country's economy and industrial construction, the amount of solid waste in mining, industry and cities has increased year by year. On the one hand, the transportation of solid waste takes up a lot of resources, and on the other hand, the stacking of solid waste occupies a large area of ​​land. Seriously polluting the environment, the treatment of solid waste has become more severe. At the same time, after the minerals are extracted, a large area of ​​goaf will appear in the mining area. If the goaf is not filled, it will cause subsidence and cause the surface to sink. In order to prevent surface subsidence and realize green mining, it is necessary to fill goafs, especially those under buildings, railways and water bodies. [0003] The previous filling technology is to fill...
