[0011] 1. The utility model sets a separation tube and spiral blades in the tube, and the separation tube presents a certain inclination angle with the ground. In the separation tube, fine sand and water are effectively separated and dehydrated according to the difference in particle size and density through the rotation and inclination of the spiral. Due to the difference in density between fine sand and water, and a certain centrifugal effect generated when the spiral blades rotate, solid fine sand is driven upward by the spiral blades, while water is difficult to move upward with the spiral blades due to its greater density. The entire separation tube is set inclined, so under the action of gravity, the water will flow to the bottom of the separation tube and be discharged from the water outlet pipe, and the fine sand will be transported to the sand outlet pipe along with the transmission of the spiral blades, thereby achieving the separation and recovery of fine sand and water.

Due to the difference in particle size and density, the fine sand and water are effectively separated and dehydrated through the rotation and inclination of the spiral. Due to the difference in density between fine sand and water, and a certain centrifugal effect will be generated when the spiral blades 4 rotate, the solid fine sand will be driven upward by the spiral blades 4, while the water is difficult to move upward with the spiral blades 4 due to its greater density, and the overall separation tube 1 is inclined, so it will flow to the bottom of the separation tube 1 under the action of gravity and be discharged from the water outlet pipe 6, and the fine sand will be transported to the sand outlet pipe 5 along with the transmission of the spiral blades 4, thereby achieving the separation and recovery of fine sand and water. The triangular support frame 7 is convenient for enhancing the overall installation strength of the separation tube 1, and the feed pipe 8 is convenient for guiding the mixture of fine sand and water into the separation tube 1. The trapezoidal shape of the trapezoidal box 9 is similar to a funnel, which can better guide the water-sand mixture. The large-volume impurities and coarse sand inside the water-sand mixture can be filtered out first through the screen 11.

[0025] Working principle: When the device is used, the cover plate 13 is first opened and the water-sand mixture is guided to the temporary storage box 12. The water-sand mixture first passes through the screen 11 to pass through the first layer of filtration. In this layer, large-volume impurities and coarse sand in the mixture are filtered out, and then the filtered mixture enters the separation tube 1. In the separation tube 1, according to the difference in particle size and density, the fine sand and water are effectively separated and dehydrated through the rotation and inclination of the spiral. Due to the difference in density between fine sand and water, and a certain centrifugal effect when the spiral blades 4 rotate, the solid fine sand will be driven upward by the spiral blades 4, while the water is difficult to move upward with the spiral blades 4 due to its greater density, and the overall separation tube 1 is inclined, so it can flow to the bottom of the separation tube 1 under the action of gravity and be discharged from the water outlet pipe 6, and the fine sand is transported to the sand outlet pipe 5 along with the transmission of the spiral blades 4.
