Equipment for conveying sand in water flow carrier by long distance

Abstract

The invention discloses equipment for conveying sand in a water flow carrier by a long distance. The equipment comprises a conveying device, a separation device, a water storage box, a pipeline and abackflow pipe. The conveying device is located in the sand conveying starting place, and the separation device and the water storage box are located in the sand conveying destination. The pipeline isarranged between the conveying device and the separation device in a connected manner, and the backflow pipe is arranged between the water storage box and the conveying device in a connected manner. The conveying device is in the starting place and is used for mixing sand and water and conveying the sand-water mixture into the separation device along the pipeline under the action of water pressure. The separation device is used for carrying out centrifugal dewatering separation on the sand-water mixture, discharging and unloading sand to the destination and discharging and unloading water intothe water storage box. The water in the water storage box flows back to the starting place from the destination along the backflow pipe and is cyclically utilized by the conveying device. The equipment has the advantages that the sand-water mixture is conveyed by a long distance by the pipeline, the sand conveying efficiency is improved, energy consumption is low, and the equipment can be suitable for various kinds of complex terrain.

Description

technical field

[0001] The invention relates to the technical field of sand transportation, in particular to a long-distance sand transportation device in a water flow carrier. Background technique

[0002] Sand has a wide range of uses. Its main application scenarios are construction, road construction, filtration, breeding and beautification. Other application scenarios are, for example, as a smelting accelerator; it is also the main material for making glass; it can also be used for cleaning and polishing use wait. Whether it is in the mining process of sand or in the process of using sand, sand needs to be transported. According to the length of the transport distance, it can be divided into short-distance transport, medium and long-distance transport and long-distance transport. The transport distance of short-distance transport is less than 200 meters, medium and long-distance conveying strokes are greater than 200 meters and less than 1,000 meters, and long-distance ...
