A steam pressurized sand-water separation and filtration device

Abstract

The invention discloses a steam pressurizing type sand-water separating and filtering device. The steam pressurizing type sand-water separating and filtering device comprises a water pump, a water storage tank and a silt filtering device, wherein a water pipe between the water storage tank and the silt filtering device is provided with a steam thrusting device which is used for thrusting an internal piston to accelerate water flow in the water pipe so as to increase the water flow pressure, and a great amount of water flow is pushed to the silt filtering device to filter and separate. Compared with the prior art, the steam pressurizing type sand-water separating and filtering device is capable of enhancing the sand-water separation speed and efficiency, and is suitable for collecting yellow sand in rivers.

Description

technical field [0001] The invention relates to a sand-water filtration and separation device, in particular to a steam pressurized sand-water separation and filtration device. Background technique [0002] Yellow sand is a particularly important building material in the field of construction. There are a lot of unmined yellow sand in major rivers and rivers. These yellow sands are of excellent quality and full of particles. Compared with other artificial sands, they have higher use value. ; but the cost of collecting yellow sand in rivers is relatively high, and the collection work generally needs to be carried out on board, because the yellow sand collected directly in rivers generally carries a large amount of river water. The direct and least costly method is generally to place the sediment, then pump out the upper part of the water and retain the lower part of the yellow sand, which requires the load capacity of the ship. The single collection volume of a ship with low ...

Problems solved by technology

The equipment mainly dehydrates by pouring sand and water into its hollow spiral body. Although this method can realize the separation of sand and water, it cannot operate fully automatically. Moreover, the hollow spiral body needs to consume more energy when loaded with a large amount of sand and water.

[0004] Another example is a kind of sand-water separator with patent number 200820076957.4. The waterway in the tank is a roundabout labyrinth structure, and the sand and water are filtered layer by layer, and finally sand particles and water are obtained. Although the sand-water separation in this way is very effective in filtering , can effectively distinguish between sand and water, but the time required for filtration and separation is relatively long, and it is only suitable for small-scale use. For yellow sand collection operations, it seems like a drop in the bucket and cannot meet the requirements for rapid yellow sand acquisition.

[0005] Although the above two schemes can achieve sand-water separation and filtration to obtain sand with high purity, they can only be used on a small scale. Meet the requirements of large-scale, fast, fully automated, low energy consumption work
