Description

Environment-adaptive paste filling equipment Technical Field The embodiment of the application relates to the technical field of coal mine construction equipment, in particular to environment-adaptive paste filling equipment. Background Paste filling mining has been widely used in recent years as a green mining technique. The technology mixes coal mine solid waste such as coal gangue and the like with cementing materials such as cement, fly ash and the like and water to prepare paste in the form of tooth paste, and pumps the paste to a goaf under the well through a pipeline to effectively support a top plate, inhibit the top plate from collapsing and gas accumulation, realize the utilization of coal gangue resources, reduce the subsidence of the ground surface and protect groundwater resources. The main paste filling system at present adopts a ground fixed filling station mode, and the process flow comprises links of material storage, quantitative feeding, stirring pulping, pumping conveying and the like. The gangue is crushed and sieved to a specified particle size in advance by an independent crushing system, and then is sent into a stirrer by a belt conveyor. In the pulping process, a vertical stirrer is generally adopted for intensive mixing, and the paste is homogenized by a paste buffer bin, so that the system flow is long, the equipment is more, and the occupied area is large. The paste after preparation is pumped into a conveying pipeline by a high-pressure piston pump and conveyed to a downhole filling area. However, the prior art treats the paste as a homogeneous fluid for pumping, and lacks the active regulation capability of the flow state. Large-particle aggregates in the paste are randomly distributed in the conveying process, and are easy to generate strong friction and impact with the pipe wall, so that the pipeline, particularly the elbow part, is severely worn. Meanwhile, large-particle aggregate is easy to aggregate in a local area to form a framework structure, and is a main cause for causing pipe blockage accidents. The treatment of the blocked pipe is difficult and takes a long time, and the continuity and the safety of the filling operation are seriously affected.
