Description

TECHNICAL FIELD

[0001] The utility model relates to water recycling technical field especially relates to a sand washing water recycling device. BACKGROUND

[0002] Sand washing is mainly used for removing the soil, dust and other impurities on the surface of sand and gravel to improve the quality of sand and gravel, and in this process, a large amount of water is used to flush the sand and gravel, thereby producing a large amount of sewage containing silt and fine particles. Currently, in order to realize the recycling of sand washing sewage, the common method is to guide the sewage into a sedimentation tank through a slurry pump, and in the sedimentation tank, the sewage reacts with the flocculating agent added in advance to promote the silt particles in the sewage to coagulate into larger lumps, thereby realizing the separation of silt and water. After this treatment, the separated clean water is discharged through the water outlet and is used for sand washing again, thereby forming a cycle.

[0003] In the traditional sand washing water sedimentation technology, the water flow in the sedimentation tank is static, which leads to insufficient contact between the flocculating agent and the suspended matter, thereby affecting the sedimentation efficiency and water quality, and ultimately may cause the effluent to be substandard, and unable to realize effective separation and recycling of silt and water.

[0004] To solve the above problems, the sand washing water recycling device is provided in the present application. UTILITY MODEL CONTENTS

It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0022] As shown in Figures 1-3 the present application provides a sand washing water recycling device, which comprises a sedimentation circulation tank 1;

[0023] In this embodiment, a cavity is formed in the sedimentation circulation tank 1, and a partition disc 2 is installed in the middle of the cavity, which divides the cavity into an independent sedimentation chamber and an assembly chamber.

[0024] In this embodiment, two pumping and discharging members 3 are installed on both sides of the top of the partition disc 2 and located in the sedimentation chamber, and a filter member 4 is installed on each of the two pumping and discharging members 3.

[0025] In this embodiment, the pumping and discharging member 3 comprises a pumping and discharging cylinder 31 arranged in the sedimentation chamber, and reciprocating chambers are formed in the two pumping and discharging cylinders 31. Connecting pipes 32 are connected to the bottom ends of the two pumping and discharging cylinders 31 on the side close to each other and communicate with the interiors of the two pumping and discharging cylinders 31. Openings are formed in the top of the pumping and discharging cylinder 31 and communicate with the reciprocating chambers. Piston parts 33 are slidably arranged in the reciprocating chambers. The top ends of the piston parts 33 extend out of the reciprocating chambers. The filter member 4 is installed on the top ends of the two piston parts 33. The piston part 33 comprises a piston body 331, which is slidably arranged in the reciprocating chamber of the pumping and discharging cylinder 31. A movable rod 332 is installed on the piston body 331, and the top end of the movable rod 332 extends out of the reciprocating chamber. The filter member 4 is installed on the top ends of the two movable rods 332. The filter member 4 comprises filter blocks 41 and filter screens 42. The filter blocks 41 are installed on the top ends of the two movable rods 332. A filter channel is formed in the middle of the filter block 41, and the filter screen 42 is installed in the filter channel.

[0026] In this embodiment, the assembly chamber is provided with a driving member 5 for driving the filter member 4 to shake up and down and driving the suction member 3 to reciprocate to suck and discharge the liquid. The driving member 5 comprises a servo motor 51 which is installed on the inner wall of the bottom of the sediment circulation tank 1 and located in the assembly chamber.

[0030] In specific embodiments, the outer periphery of the sediment circulation tank 1 is provided with a mud suction pump 7 which communicates with the sediment chamber. The mud suction end of the mud suction pump 7 is located below the filter member 4.
