Preparation method of a combined device for collecting gold sand

Abstract

The invention relates to a preparation method for a combined device for collecting gold sand. According to the preparation method for the combined device for collecting the gold sand, a movable type conveying groove capable of crushing ore sand and a width-increasing type grading gold storage chute are arranged, then the two separate devices are combined together according to the condition of an operation area, and therefore the purpose of simultaneously collecting fine-particle gold sand and large-particle gold sand in the operation area can be realized; a conveying groove body in the movable type conveying groove capable of crushing the ore sand is beneficial to raw material conveying, and sufficient time and a working site are provided for dissolving and crushing mineral aggregate; the conveying groove body with three levels corresponding to three gradient surfaces can improve the crushing efficiency of crushing the mineral aggregate by water pressure step by step; large-particle gold grains of the width-increasing type grading gold storage chute flow into a material distribution groove along with ore pulp with higher flow speed, and the fine-particle gold sand is reserved on a flat plate groove with a large enough area; and meanwhile, due to the design of multiple columns and multiple rows of water distribution ports, finer-particle gold grains which flow from the water distribution ports to all layers of flat grooves respectively are all reserved on gold felt of each layer of gold felt beds.

Description

technical field [0001] The invention relates to a method for preparing a device for collecting gold sand, in particular to a method for preparing a combined device for collecting gold sand. Background technique [0002] The collection of ore sand and alluvial gold has existed since ancient times, and the purpose of panning for gold is realized under the action of water flow with the help of tools such as troughs and slides. [0003] Chinese Patent Publication No. CN101298063A discloses titled "A River Sand Mineral Concentrator", which comprises a water-washing dressing device, an ore sorting device and a power plant, and the water-washing dressing device and the ore sorting device are respectively connected with the power unit, and the water-washing dressing device includes The transmission device and the rotating device with the gold-absorbing blanket as the transmission belt. The ore sorting device includes a sorting tank and a sorting plate. One end of the water washing o...

Problems solved by technology

However, practice has proved that the acquisition of fine particle placer gold is not ideal with the above-mentioned equipment.

For example, it is possible to extract alluvial gold in a way that the specific gravity of alluvial gold is greater than that of mercury, but it cannot be guaranteed that the mercury gas recovery device will not escape when it involves specific working conditions, making it difficult to guarantee environmental protection, and heavy metal pollution. The hazards are difficult to eliminate in a short time

Another example is that the equipment characterized by the structure of the tank, the cylinder or the combination of the two, although gold felt is also used, but because the working area of ​​the tank or the cylinder is limited by its own volume, when the sand is flushed with a large amount of water, the placer The gold sand in the sand is easy to wash away, and it is not easy to separate the gold sand from the ore sand quickly when washing the sand with a small amount of water. At this time, the effect of the gold felt is also minimal.
