Equipment for filling according to depth of collapse pit of decommissioned uranium mine

Abstract

The invention provides equipment for filling according to the depth of a collapse pit of a decommissioned uranium mine. The equipment comprises a main body; a fixed part is fixedly mounted in the main body; a limiting push assembly is fixedly mounted on the lower side of the main body; air bag linkage assemblies are fixedly mounted on the left and right sides of the inner wall of the main body; the upper side of each air bag linkage assembly is connected with a gear linkage assembly; the upper end of each gear linkage assembly is movably connected with a material limiting assembly; and each material limiting assembly comprises a mounting block. According to the equipment for filling according to the depth of the collapse pit of the decommissioned uranium mine, along with continuous adding and filling of fillers, when the collapse pit of the decommissioned uranium mine is gradually filled with the fillers, the upper ends of movable push rods are used for driving material limiting baffles to move relatively, and the material limiting baffles are prompted to be in a mutual closed state, so that the equipment achieves the purpose of automatic closing when the collapse pit of the uranium mine is filled up; and the equipment does not need the assistance of manual supervision, so that the labor intensity of workers is reduced, and the practicability of the equipment is further improved.

Description

technical field [0001] The invention belongs to the technical field of uranium mines, and in particular relates to a filling device according to the depth of a subsidence pit of a decommissioned uranium mine. Background technique [0002] Uranium ore has soil, powder, block, stalactite, kidney, etc. Some soil-like uranium is called uranium black, while the block is called pitchblende. Soil-like uranium ore has no What luster, blocky ones have asphalt luster. Uranium ore is a dangerous mineral with radioactivity. In addition to extracting uranium for the nuclear industry, they can also extract radium and other rare earth elements from it. Uranium is an extremely rare radioactive substance. The average content of metal elements in the earth's crust is only two parts per million, and the probability of forming industrially usable deposits is much smaller than that of other metal elements. [0003] Nowadays, with the rapid development of the world economy, environmental protect...

Problems solved by technology

[0003] Nowadays, with the rapid development of the world economy, environmental protection and the continuous depletion of fossil energy, the development and utilization of large-scale nuclear energy has become an inevitable choice. There are uncontrollable factors in the continuous mining of ore. Due to the diffusion and migration of ore piles, it is easy to cause the collapse of uranium mines, and this phenomenon occurs in uranium mine tailings reservoirs, which has a great impact on the safety and environmental protection of mines. , so there are potential safety hazards. Therefore, a kind of equipment for efficiently filling the subsidence pits of uranium mines is needed
