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.
[0037] Refer to Figure 1 、 Figure 2, an embodiment provided by the present utility model: a sand and gravel separation and dehydration device, including a dehydration tank 1. On the upper side of the inner wall of the dehydration tank 1, there is an interception box 4. Inside the inner wall of the interception box 4, there are multiple sieve holes 12 for filtering out the slurry water in the sand and gravel slurry water. On both sides of the top of the interception box 4, there are fixedly connected clamping frames 5 for hanging the interception box 4 on the inner wall of the dehydration tank 1. The inner wall of the clamping frame 5 is clamped on one side of the top of the dehydration tank 1. A filter screen plate 3 is located on the right side of the inner wall of the dehydration tank 1 for filtering out the water in the slurry water. The outer wall of the filter screen plate 3 is closely attached to the inner wall of the dehydration tank 1. Arc grooves 15 are opened on both the front and rear sides of the filter screen plate 3. A drain pipe 2 is fixedly connected to the lower part on the right side of the dehydration tank 1 where the filter screen plate 3 is located. On the left side of the filter screen plate 3 inside the inner wall of the dehydration tank 1, there is a push plate 14. The shape of one side of the outer wall of the push plate 14 fits the shape of the inner wall of the dehydration tank 1. One end of the push plate 14 is in contact with one end of a convex strip 13 for pushing the deposited slurry out of the dehydration tank 1. The top end of a threaded rod 9 is rotatably connected to a top plate 10. One end of the top plate 10 is fixedly connected to the upper part of the front side of the dehydration tank 1.
[0038] Specifically, pour the sand and gravel slurry water into the interception box 4. The slurry water is screened out through the sieve holes 12 and flows into the inside of the dehydration tank 1, while the sand and gravel will stay in the interception box 4 under the obstruction of the interception box 4. Then, remove the clamping frame 5 from the dehydration tank 1 and take out the interception box 4 together with the interception box 4 from the inside of the dehydration tank 1 to facilitate the cleaning of the sand and gravel. The slurry water flowing into the dehydration tank 1 will be filtered by the filter screen plate 3, so that the slurry stays on the left side of the inner cavity of the dehydration tank 1, and the filtered water will pass through the right side of the inner cavity of the dehydration tank 1 and be discharged outward along the drain pipe 2.
[0039] Refer to Figure 3 , Figure 4 , on the front side of the dehydration tank 1, at the bottom of the threaded rod 9, there is a bottom plate 6 fixedly connected. The bottom end of the bottom plate 6 is fixedly connected with a motor 7. The driving end of the motor 7 penetrates through the bottom plate 6 and is fixedly connected to the bottom of the threaded rod 9. The outer wall of the threaded rod 9 is threadedly connected with a sliding plate 8. One end of the sliding plate 8 is slidably connected to the front side of the dehydration tank 1. The other end of the sliding plate 8 is fixedly connected with a concave-shaped frame 11. One side of the bottom of the concave-shaped frame 11 is fixedly connected to the top of the push plate 14. On both sides of the filter screen plate 3 inside the inner wall of the dehydration tank 1, there are convex strips 13 fixedly connected. The shape of the outer wall of the convex strip 13 fits the shape of the inner wall of the arc groove 15.
[0040] Specifically, due to the shape fit between the convex strip 13 and the arc groove 15, the filter screen plate 3 can be taken out from the dehydration tank 1, which is convenient for cleaning the filter screen part of the filter screen plate 3, avoiding the blockage of the filter screen by the slurry and affecting the subsequent filtration efficiency. Start the motor 7, so that the sliding plate 8 slides upward in a threaded manner and drives the concave-shaped frame 11 to move upward, making the other end drive the push plate 14 to slide upward and push out the deposited slurry, thereby facilitating the staff to clean the slurry and improving the work efficiency.
[0041] Working principle: First, pour the sand, gravel and slurry water into the interception box 4. The slurry water is screened out through the sieve holes 12 and flows into the inside of the dehydration tank 1. The sand and gravel will stay in the interception box 4 under the obstruction of the interception box 4. Then, remove the clamping frame 5 from the dehydration tank 1 and take out the interception box 4 from the inside of the dehydration tank 1 together to clean the sand and gravel. The slurry water flowing into the dehydration tank 1 will be filtered by the filter screen plate 3, so that the slurry stays on the left side of the inner cavity of the dehydration tank 1, and the filtered water will pass through the right side of the inner cavity of the dehydration tank 1 and drain out along the drain pipe 2. After the dehydration is completed, start the motor 7 to make the slide plate 8 slide upward in a threaded manner and drive the concave frame 11 to move upward, so that the other end drives the push plate 14 to slide upward and push out the deposited slurry, which is convenient for the staff to clean the slurry and improve the work efficiency. Due to the shape fit between the convex strip 13 and the arc groove 15, the filter screen plate 3 can be taken out of the dehydration tank 1, which is convenient for cleaning the filter screen part of the filter screen plate 3 and avoiding the slurry from blocking the filter screen and affecting the subsequent filtration efficiency.
