Problems solved by technology

The traditional mine paste filling technology is to process coal gangue, construction waste, fly ash, cement and a small amount of admixtures, etc., and mix them with water according to a certain ratio to make a filling slurry on the ground, and inject it through the ground. The slurry system and transportation pipelines are transported to the underground goaf, but the paste filling materials still have problems such as poor fluidity of the filling slurry, easy plugging of the pipe, and low strength of the paste filling body in the early stage, which curbs the paste filling mining technology wide application of

Abstract

The invention discloses a mining paste filling material magnetizing device, which comprises a cylinder, a partition plate is fixedly connected in the cylinder, the partition plate divides the cylinder into a material mixing chamber and a magnetizing chamber from top to bottom, and a gate part is arranged on the partition plate; a plurality of feed hoppers and a plurality of water inlet pipes are fixedly connected to the outer wall of the top end of the barrel and are communicated with the mixing chamber; the stirring mechanism comprises a transmission part fixedly connected to the top end of the barrel, a driving motor is fixedly connected to the top end of the transmission part and is in transmission connection with the transmission part, and the output end of the transmission part extends into the mixing chamber and is fixedly connected with a stirring part; the magnetizing mechanism comprises a discharging pipe fixedly connected to the inner wall of the top end of the magnetizing chamber, the tail end of the discharging pipe extends out of the cylinder, and the mixing chamber is communicated with the discharging pipe through a gate part; an auxiliary discharging part is installed in the discharging pipe, permanent magnets are symmetrically arranged on the two sides of the discharging pipe, and the two permanent magnets are detachably connected into the magnetizing chamber. The magnetization of the paste can be realized, and the flowability of the paste is enhanced.

Description

Technical field [0001] The present invention relates to the field of mine filling technology, in particular to a mineral paste filler magnetization device and method of use. Background [0002] With the continuous reduction of high-quality underground resources, the "three down" resource mining has gradually become an important means for major mining enterprises to extend the service life of mines. Therefore, the development and application of filling technology has gradually become a key technology in the mining industry. The traditional mine paste filling technology is to process the coal gangue, construction waste, fly ash, cement and a small amount of admixtures, etc., mix with water according to a certain ratio, make a filling slurry on the ground, and transport it to the underground goaf area through the ground grouting system and transportation pipelines, etc., but the paste filling material still has poor fluidity of the filling slurry, easy to block the pipe, and the low...
