Embodiment Construction

[0015] Make the sand taking device: it includes a pontoon 2, a sand suction pump 3 fixed on the pontoon 2, and a high-pressure water gun 5. The high-pressure water gun 5 is provided with three gun barrels, and the three gun barrels are fixed on the suction pipe 4 of the sand suction pump in parallel and evenly distributed. At the front end, the pontoon 2 is provided with a bracket 7 and a winch 1, the top of the bracket 7 is provided with a pulley, and the steel cable of the winch 1 passes through the front end of the pulley to connect with the suction pipe 4 of the sand suction pump, so that the winch 1 can lift the suction pipe of the sand suction pump 4 and high pressure water gun 5.

[0016] Sand extraction: place the floating boat 2 in the tailings pond, input the front end of the suction pipe 4 of the sand suction pump into the high-pressure water gun 5 to impact the tailings to make slurry, use the sand suction pump 3 on the floating boat 2 to inhale, and exit from the s...

Abstract

The invention discloses a method for taking sand from a tailings pond and a sand taking device. The sand taking method is to install a movable floating boat in the tailings pond, a sand suction pump is fixed on the floating boat, and the front end of the suction pipe of the sand suction pump is equipped with a high-pressure water gun for impact The tailings are made into slurry, sucked by the sand suction pump, flow out from the outlet of the sand suction pump, and transported to the predetermined position to realize sand extraction from the tailings silo. The invention can realize the extraction of sand in the tailings dam, which not only meets the concentration requirements for the extraction of valuable elements, but also realizes continuous operation, not only takes the tailings of the tailings to fill the goaf, but also extracts the valuable elements , so it has great social and economic benefits.

Description

technical field [0001] The invention relates to a method for taking sand from a tailings pond and a sand taking device. Background technique [0002] At present, there are more than 3,000 medium and large tailings ponds in the country. Tailings ponds play an important role in mine construction, but tailings ponds require a lot of investment and occupy a lot of mountainous land. For old tailings ponds or in-use tailings ponds Sand, not only to increase the storage capacity, but also has a good prospect for reusing the valuable resources in the early discharge tailings. [0003] There are many old mines in my country. Due to the geological conditions, the rock under the pit is soft and the stability of the surrounding rock is poor. Since the late 1960s, most mines in my country have continued to use concrete and graded tailings to deal with goafs. With the development of production, concrete filling pillars have been used for more than 30 years, and there are low production c...
