Filling body self-rotation stirring device and process thereof

Abstract

The invention provides a self-rotating stirring device for a filling body and a process thereof, and relates to the technical field of mine equipment, and the adopted scheme is that the self-rotating stirring device comprises a cement paste pipe, a rotating stirring pipe and a gangue conveying mechanism, the rotary stirring pipe comprises a third-stage forward vortex flow channel section, a second-stage reverse vortex flow channel section and a first-stage forward vortex flow channel section which are sequentially and continuously arranged from top to bottom and are all of an arc-shaped structure, and the cement slurry inlet and the gangue particle inlet are located in the first-stage forward vortex flow channel section. The gangue particle inlet is closer to the second-stage reverse vortex flow channel section relative to the cement slurry inlet, the mixture outlet is located in the third-stage forward vortex flow channel section, and a connecting line between the center of the cement slurry inlet and the center of the mixture outlet is obliquely arranged and forms an inclination angle a with the vertical direction. The problems that an existing paste pumping filling mode is high in investment and large in occupied area, and safety accidents are easily caused due to the fact that the pressure is high during long-distance conveying of a conveying pump are solved.

Description

technical field

[0001] The invention relates to the technical field of mine equipment, in particular to a filling body self-rotating stirring device and a process thereof. Background technique

[0002] In order to reduce the deformation of the ground surface after mining, it is usually necessary to carry out various filling methods on the mining roadway. Among them, the method with better effect, that is, the method that can form a better filling body is mainly pumping paste filling, pumping paste filling Special equipment such as cement silos, gangue silos, mixing stations, conveying pumps, etc. are required, and more equipment and sites will be used. After the above equipment and links are processed, a well-mixed filling body can be formed.

[0003] It can be seen that the current pumping paste filling method has the problems of high investment and large occupied area, and when the pump is used for long-distance transportation, the pressure is high and there are potential ...
