Abstract

The invention provides a coal slipping energy recovery device for coal mines, which is used for solving the waste problem in the coal transportation process. The slipping energy recovery device comprises a coal chute and a chamber, and a hanging point and a spray head are respectively arranged at the top of the chamber. The chamber is connected with a connection roadway through a transition section, and a kinetic energy capture device is arranged in the chamber and is connected with the input shaft of a gearbox. The output shaft of the gearbox is connected with the main shaft of a permanent magnet generator. Coal slips down at high speed in the coal chute, coal potential energy is converted into kinetic energy. When the coal falls on a kinetic energy capture turbine, the blades of the kinetic energy capture turbine are impacted and are pushed to rotate. Finally, the conversion of mechanical energy of coal slipping to electric energy is realized. The economic benefit of coalmine production is improved.

Description

technical field [0001] The invention relates to the technical field of energy saving in coal mine production, in particular to a recovery device for the energy of coal slid in a coal mine. Background technique [0002] Coal slipping is a transportation method in coal mine production. Coal falls freely through the coal slip hole (a vertical roadway with a small section or a large dip angle roadway), impacts and falls into the coal hopper at the bottom or the coal bunker with slip eye and then transfers to the mine. Car or belt transfer, coal mines have a large number of sliding coal eyes, and the height generally ranges from 10 meters to 100 meters. It is wasted in vain due to friction, and at the same time, it increases the energy consumption of lifting coal from the coal bunker at the bottom of the well to the ground. Based on the calculation of the 30-meter-high sliding coal hole, the potential energy wasted for each ton of coal produced in this process is E=mgh=1000 *9.8*30...
