Description

Technical Field

[0001] The invention belongs to the technical field of mining water tank sludge cleaning, and in particular relates to a mining water tank sludge cleaning system. Background Art

[0002] When the silt in the mine water tank reaches a certain amount, it must be cleaned. At present, the commonly used methods for desilting the water tank in mines include: (1) Manual cleaning: Use a shovel to shovel the sludge into a sack or mine car, carry it on your shoulders, push it by hand or use a winch to pull it out of the bin, filter it dry and then transport it to the goaf or lift it to the ground for storage. This method is labor-intensive and inefficient, and the mud is spilled along the way, polluting the environment.

[0003] (2) The use of mechanized excavation such as loaders and scraper conveyors can reduce the labor intensity of workers and speed up the cleaning process. Compared with manual cleaning, the efficiency is greatly improved. However, due to the limited space in the water tank, mechanical excavation is often not able to be carried out, which makes it very inflexible and the excavation effect is average. In addition, there is still the problem of mud spilling along the way and polluting the environment during transportation.

[0004] (3) Use a complete set of equipment for clearing and filtering. After the water jet slurry suction, pipeline pumping out of the bin, and solid-liquid separation in the filter press, the clean water flows back to the water bin, and the dry material is transported to the ground for storage. This method solves the problem of difficulty in dredging sludge and mud spilling along the way to pollute the environment to a certain extent, but it also has the disadvantages of complex procedures, high requirements for equipment linkage, and low efficiency. After the dry material is hoisted and transported to the surface by belt conveyors, mine cars, vertical shafts, etc., it must be transferred to the yard by mine trucks for retention. During the transportation process, it will also cause pollution to the hoisting and transportation lines and the surface environment.

[0026] As shown in Figure 1 to Figure 8As shown, the present invention provides a mining water tank sludge cleaning system, which includes a mining tank cleaning machine 1, a mining concrete delivery pump 2 and a feeder. The mining tank cleaning machine 1 is provided with a digging mechanism 9 and a first pumping mechanism 23; the digging mechanism 9 is used to clean the sludge and transfer it to the first pumping mechanism 23; the mining concrete delivery pump 2 is provided with an upper stirring mechanism 39, a second pumping mechanism 49 and a power mechanism. The upper stirring mechanism 39 is integrated with the working frame 38, or can be split. The power mechanism is respectively connected to the upper stirring mechanism 39 and the second pumping mechanism 49 to drive the upper stirring mechanism 39 and the second pumping mechanism 49 to operate. The discharge port 67 of the feeder is connected to the feed port 46 of the upper stirring mechanism 39 to provide cementitious material to the upper stirring mechanism 39. The discharge port 48 of the upper stirring mechanism 39 is connected to the feed hopper 50 of the second pumping mechanism 49; the first pumping mechanism 23 is connected to the feed port 46 through the feeding pipeline 73 to transport sludge to the upper stirring mechanism 39; the second pumping mechanism 49 is connected to the goaf filling area through the discharge pipeline 74 to transport the sludge after mixing the cementitious material to the goaf filling area. The cementitious material includes cement, quicklime and other cementitious solidifying materials, which can change the gap structure between the sludge particles, increase the strength and stability of the sludge, and thus meet the requirements of filling the goaf filling area.

[0027] The mining water tank sludge cleaning system provided by the present invention does not send the sludge to the well after the water tank is cleaned. Instead, the sludge is directly pumped to the goaf filling area by adding a certain proportion of cementitious materials and stirring and mixing. This method does not require the sludge to be lifted to the surface, nor does it require a yard to be set up on the surface, which solves the problem of mud stacking and spilling along the way to pollute the environment, while taking into account the filling of the goaf, and has the advantages of simple process, green environmental protection, high efficiency and low comprehensive cost.
