DETAILED DESCRIPTION

[0022] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0023] Embodiment: Referring to the following Figure 1 A convenient sand washing device according to a preferred embodiment of the utility model is described in detail:

[0024] like Figure 1 A convenient sand washing device is shown, comprising a support 1, a dewatering tank 2 and a dewatering unit 3, wherein the dewatering tank 2 is arranged on the support 1, and the dewatering unit 3 is arranged in the dewatering tank 2, and an opening is arranged at one end of the dewatering tank 2, and the dewatering tank 2 is arranged obliquely, and the open end of the dewatering tank 2 is lower than the sealed end, and a partition 5 is arranged above the bottom plate 201 at the open end of the dewatering tank 2, and a sealing plate 6 is arranged between the partition 5 and the bottom plate 201 to seal the bottom plate 201 and the partition 5 into a cavity structure with one end open, and a water outlet penetrating the upper and lower surfaces of the bottom plate 201 is provided on the bottom plate 201 at the open end of the dewatering tank 2, and a sealing plate 6 is provided between the partition 5 and the bottom plate 201. A joint with a diameter of 20 cm is welded at the corresponding water outlet, and a water outlet pipe 7 is connected to the joint. An inclined dewatering screen 4 is provided at the sealed end of the dewatering tank 2. The dewatering screen 4 is located above the dewatering unit 3 and is arranged horizontally along the dewatering unit 3. The lower end of the dewatering screen 4 is located on the bottom plate 201 of the dewatering tank 2. The dewatering screen 4 is connected to the sand pumping pipe 8. The dewatering screen 4 includes a screen 401 and a screen frame 402. The screen 401 is fixed in the screen frame 402. The screen 401 is a supporting net with a mesh diameter of 1.5 cm. One end of the dewatering screen 4 is fixedly connected to the dewatering tank 2 through a vertically arranged support rod 9.

[0025] The dewatering unit 3 is located above the dewatering trough 2. There is a channel formed by a gap between the bottom surface of the dewatering unit 3 and the upper surface of the bottom plate 201 of the dewatering trough 2 for water and impurities to pass through. The dewatering unit 3 is overlapped on the partition 5 so that the river sand on the dewatering unit 3 can fall from the open end of the dewatering trough 2 through the partition 5.

[0026] When the sand washing device of this embodiment is used for sand washing, the river water containing river sand is directly hit on the dewatering screen 4 through the pump and the sand pumping pipe 8. The larger stones and mud blocks will be blocked by the screen 401 and slide down to the bottom plate 201 along the screen 401. Since the dewatering trough is inclined toward the water outlet, the stones and mud blocks that slide down to the bottom plate 201 enter the water outlet along the bottom plate 201 together with the water and are discharged along the outlet pipe 7. The water inlet end of the outlet pipe 7 is connected to the joint, and the water inlet end of the outlet pipe 7 is higher than the water outlet end, so as to discharge muddy water and impurities. The river sand falling from the screen 401 will fall on the dewatering unit 3 for dehydration again. The river sand will be blocked by the dewatering unit 3 and directly flow into the sand pile. The river water will directly flow into the channel of the bottom plate 201 and the dewatering unit 3 through the dewatering unit, and will be discharged together with the stones and mud blocks that roll down from the dewatering screen 4 through the outlet pipe 7 at the end.

[0027] The bracket 1 of this embodiment includes three support rods 101 and oblique support rods 102 arranged between the three support rods 101. The three support rods 101 are arranged in a triangle. A horizontal support rod 101 is fixedly connected to the middle position of the bottom surface of the dewatering trough 3. The dewatering trough 3 is tied to two vertical rods 101 by horizontal support rods 103 and iron wires. The remaining vertical rod 101 is fixedly connected to the sealed end of the dewatering trough by iron wire. The bracket has a simple structure and is easy to disassemble and install, and the inclination angle of the dewatering trough 2 can be adjusted as needed.

[0028] In the present embodiment, the dehydration unit 3 comprises a dense mesh, a buffer mesh and a support mesh arranged in sequence from top to bottom. The dense mesh is a gauze screen of 60 meshes, the buffer mesh is a plastic screen with a mesh diameter of 1.2 cm, and the support mesh adopts a steel wire screen with a mesh diameter of 1.5 cm. The support mesh is fixed on a mesh frame (not shown in the figure), and the mesh frame is installed on the wall plate of the dehydration tank 2 by a bolt assembly, and the buffer mesh is laid on the support mesh and tied to the support mesh by iron wire, and the dense mesh is laid on the buffer mesh, and the dense mesh is folded downward and pressed between the buffer mesh and the support mesh, thereby fixing the dense mesh, so that the design is convenient for replacing the dense mesh. The steel wire screen is used to support the upper two layers of nets, and the plastic net in the middle plays a buffering role, because if the gauze screen is directly laid, the gauze screen will fall down, and if the steel wire screen is not laid, the plastic screen and the gauze screen will be washed out after a period of time, and need to be replaced frequently. If the plastic screen is not laid in the middle, the gauze screen will be in direct contact with the wire screen and will also deteriorate very quickly. The top dense mesh plays a filtering role, and the two layers of mesh below are mainly used to protect the dense mesh, increase the use cycle, and extend the service life.

[0029] In this embodiment, if Figure 1 As shown, the dewatering trough includes a bottom plate 201, an end plate 202 fixed at one end of the bottom plate 201, and side plates 203 fixed at both sides of the bottom plate 201. The end surfaces of the two side plates 203 close to one end of the end plate 202 are fixedly connected to the end plate 202. The length of the bottom plate 201 is greater than that of the side plates 203, so that the end of the bottom plate 201 away from the end plate 202 extends out of the side plate 203, so that the extended bottom plate 201 acts as a material sliding plate.

[0030] In this embodiment, one side of the bottom plate 201 at the sealed end of the dewatering trough 2 extends outward so that the bottom plate forms an L shape, so that the lower end of the dewatering screen 4 is placed on the bottom plate 201, so that larger stones and mud blocks fall from the screen 401 onto the bottom plate 201.

[0031] In other embodiments of the present invention, an avoidance gap is provided on one side of the dehydration unit 3 close to the bottom end of the dehydration screen 4 so that the lower end of the dehydration screen is placed on the bottom plate 201 .
