Description

Technical Field

[0001] This application relates to the field of sand and gravel separation, and in particular to a sand and gravel separation device. Background Art

[0002] The commercial concrete mixing station introduces a combination of a sand and gravel separator, a filter press, and a clean water collection tank. When the commercial concrete transport vehicle arrives at the position of the sand and gravel separator, water is automatically supplied to the commercial concrete transport vehicle. The commercial concrete transport vehicle will first rotate forward so that the clean water can clean the inside of the commercial concrete transport vehicle. After rotating for a certain period of time, it will rotate in reverse to discharge the sand and gravel slurry water in the commercial concrete transport vehicle. At this time, the sand and gravel slurry water will enter the guide trough of the sand and gravel separator and then enter the separation mechanism of the sand and gravel separator for separation. The stones and gravel will be discharged from different outlets of the sand and gravel separator respectively, and the slurry water will be transported to the filter press for further solid-liquid separation. The separated clean water will be transported to the clean water collection tank.

[0008] By adopting the above technical solution, when the servo motor starts to work, it can drive the gear and the roller to rotate. When the gear rotates, it can roll along the rack, thereby driving the sliding seat to move along the rack, so that the roller can move along the rack while rotating, so that each row of top columns can alternately penetrate through each row of sieve holes, and then eject the stones stuck inside the sieve holes, thus realizing the rapid cleaning of the stones stuck inside the sieve holes and improving the cleaning efficiency of the sieve plate.

[0009] Optionally, on the top of the bottom plate are symmetrically fixedly connected with side plates.

[0010] By adopting the above technical solution, the side plates are provided to surround the screened sand and gravel to reduce the probability of the sand and gravel rolling down from both sides of the sieve plate.

[0019] In summary, the beneficial effects of the present application are as follows:

[0020] In the present application, through the arrangement of the top column, the gear and the servo motor, when the servo motor starts to work, it can drive the gear and the roller to rotate. When the gear rotates, it can roll along the rack, thereby driving the sliding seat to move along the rack. Thus, when the roller rotates, it can also move along the rack at the same time, so that each row of top columns can alternately penetrate each row of sieve holes, and then eject the stones stuck inside the sieve holes, thereby realizing the rapid cleaning of the stones stuck inside the sieve holes and improving the cleaning efficiency of the sieve plate.
