Detailed Description of the Preferred Embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-5, the present utility model provides a technical solution: a sand washing device for construction engineering, including a sand conveying cylinder 1 and a support frame 2. The sand conveying cylinder 1 is inclined and installed on the support frame 2. A rotating shaft 3 is rotatably installed inside the sand conveying cylinder 1. The rotating shaft 3 is driven to rotate by a motor, and spiral blades 4 are provided on the surface of the rotating shaft 3;

[0024] A water spraying pipe 5 is provided above the right side of the sand conveying cylinder 1. The water spraying pipe 5 is fixedly installed on the support frame 2. One end of the water spraying pipe 5 is connected to a water conveying pipe 6. A plurality of water spraying nozzles 7 are provided on the water spraying pipe 5, and the water spraying nozzles 7 correspond to the inside of the sand conveying cylinder 1;

[0025] The upper end of the sand conveying cylinder 1 is open. An inlet 15 is provided at the upper left side of the sand conveying cylinder 1, and an outlet 16 is provided at the lower right side of the sand conveying cylinder 1;

[0026] A drain port 17 is provided on the left side of the sand conveying cylinder 1, and a filter screen 18 is provided inside the drain port 17.

[0027] Among them, the inclined sand conveying cylinder 1 can facilitate the flow of water. The sand and gravel enter the sand conveying cylinder 1 from the inlet 15 on the left side of the sand conveying cylinder 1. The motor drives the rotating shaft 3 to rotate, so that the spiral blades 4 convey the sand and gravel to the right side of the sand conveying cylinder 1. Water source is conveyed into the water spraying pipe 5 through the water conveying pipe 6, so that the water spraying nozzles 7 wash the sand and gravel inside the sand conveying cylinder 1. The washed sand and gravel are discharged from the sand conveying cylinder 1 through the outlet 16. Since the left side of the sand conveying cylinder 1 is lower than the right side, the water on the right side of the sand conveying cylinder 1 flows to the left side. During the rotation of the spiral blades 4, the water flow can wash the sand and gravel until the water flows to the leftmost inlet 15 and finally is discharged from the sand conveying cylinder 1 through the drain port 17. The filter screen 18 provided at the drain port 17 can filter the sand and gravel in the inlet 15 to prevent the loss of sand and gravel.

[0028] A filter plate 8 is provided at the bottom of the sand conveying cylinder 1. A flow discharge plate 9 is provided below the filter plate 8. The flow discharge plate 9 is driven to lift and lower by a hydraulic rod 10;

[0029] A diversion groove 11 is provided at the bottom of the sand conveying cylinder 1. The right side of the diversion groove 11 is closed and the left side is open. The flow discharge plate 9 is located inside the diversion groove 11;

[0030] Four groups of guide posts 12 are provided at the bottom of the sand conveying cylinder 1. Four guide holes are provided near the four corners of the flow discharge plate 9. The flow discharge plate 9 is sleeved on the four groups of guide posts 12 through the four guide holes and is slidably connected with the guide posts 12 up and down;

[0031] A sealing gasket 13 is provided on the upper surface of the flow discharge plate 9, and a plurality of reinforcing ribs 14 are uniformly arranged in an array on the lower surface of the flow discharge plate 9.

[0032] Among them, the discharge plate 9 is used to drain the excessive accumulated water in the sand conveying barrel 1. If there are more soil impurities in the sand and gravel, the viscosity of the water in the sand conveying barrel 1 will increase during the cleaning process, making the water fluidity in the sand conveying barrel 1 lower. At the same time, the spiral blades 4 will also block the water flow, making it easy for water to accumulate in the sand conveying barrel 1, affecting the subsequent sand washing. At this time, the discharge plate 9 at the bottom of the sand conveying barrel 1 is driven down by the hydraulic rod 10, so that the accumulated water flows out of the filter plate 8, and the accumulated water is transported to the left side and discharged through the guide groove 11. Then the hydraulic rod 10 drives the discharge plate 9 to rise so that the sealing pad 13 at the upper end of the discharge plate 9 can seal the filter plate 8.

[0033] The working principle and use process of this utility model:

[0034] Among them, the inclined sand conveying cylinder 1 can facilitate the flow of water. Sand and gravel enter the sand conveying cylinder 1 from the feed port 15 on the left side of the sand conveying cylinder 1. The motor drives the rotating shaft 3 to rotate, so that the spiral blade 4 conveys the sand and gravel to the right side of the sand conveying cylinder 1. Water is conveyed to the water spraying pipe 5 through the water conveying pipe 6, so that the water spraying head 7 washes the sand and gravel in the sand conveying cylinder 1. The washed sand and gravel are discharged from the sand conveying cylinder 1 through the discharge port 16. Since the left side of the sand conveying cylinder 1 is lower than the right side, the water on the right side of the sand conveying cylinder 1 flows to the left side. During the rotation of the spiral blade 4, the water flow can wash the sand and gravel until the water flows into the feed port 15 at the far left, and finally discharged from the sand conveying cylinder 1 through the drain port 17. The filter screen 18 arranged at the drain port 17 can filter the sand and gravel in the feed port 15 to prevent the sand and gravel from being lost; if there are more soil impurities in the sand and gravel, the viscosity of the water in the sand conveying cylinder 1 will increase during the cleaning process, making the fluidity of the water in the sand conveying cylinder 1 lower, and the spiral blades 4 will also block the water flow, making it easy for water to accumulate in the sand conveying cylinder 1, affecting the subsequent sand washing. At this time, the hydraulic rod 10 drives the discharge plate 9 at the bottom of the sand conveying cylinder 1 to descend, so that the accumulated water flows out of the filter plate 8, and the accumulated water is transported to the left side through the guide groove 11 and discharged, and then the hydraulic rod 10 drives the discharge plate 9 to rise so that the sealing pad 13 at the upper end of the discharge plate 9 can seal the filter plate 8.
