Transportation pipeline for filling equipment

Abstract

The invention discloses a transportation pipeline for filling equipment. The transportation pipeline comprises transportation pipe, an inner cavity and butting discs, wherein the butting discs are welded to two ends of the transportation pipe, and the inner cavity is formed in the transportation pipe; miniature vacuum pumps are symmetrically arranged close to the surfaces of any pair of the butting discs, and hoops are welded to the bottoms of the vacuum pumps and are locked on the surface of the transportation pipe in a nesting manner; and the miniature vacuum pumps further comprise power supply wires, copper pipes, air jetting pipes and positioning shafts. Air pressure is blown into the air jetting pipes via through pipes and is released by virtue of the air jetting pipes so as to drivematerials in the pipes to move, and meanwhile, the materials can be driven to rotate through curved edges during the movement of the materials, so that the relatively good directivity during the movement of the materials is realized, meanwhile, relatively large kinetic energy is generated, the transportation pipe is unlikely to be blocked, and the unloading efficiency is improved; by virtue of thecooperation with the miniature vacuum pumps, the electric energy can be saved; and by utilizing a filter net and a one-way valve, the backflow of the materials can be prevented.

Description

technical field [0001] The invention relates to the technical field of transportation pipelines, in particular to a transportation pipeline for filling equipment. Background technique [0002] Filling is a general term for the equipment, facilities, shaft engineering and structures used for collecting, processing, storing and preparing filling materials, transporting and stacking filling materials to gobs, dehydrating filling materials and treating sewage. The filling system is divided into dry filling system, water sand filling system and cemented filling system. Sometimes it is necessary to combine several filling systems. For example, the dry filling system is used to fill the goaf of the open-stop mining method, and the cemented filling system is used to mix cement mortar into the gravel filling. The existing filling method is mainly pipeline transportation. [0003] After careful analysis, it is found that the existing transportation pipeline of filling equipment has ...

AI Technical Summary

Problems solved by technology

[0003] After careful analysis, it is found that the existing transportation pipeline of filling equipment has the following shortcomings: first, the traditional straight-through structure is easy to cause blockage when feeding; second, the existing pipeline adopts a pressurized method when feeding , the fluid will flow back into the pump under negative pressure, and the installation of the pump body is more complicated and the cost is too high
