AI Technical Summary
The existing sand fishing machine will cause turbulence in the ore slurry during operation, making the coarse particles unable to sink, resulting in the outgoing ore slurry containing coarse sand, affecting the quality of the ore slurry.
An overflow sand fishing machine was designed. By setting a communication hole between the sand fishing pool and the overflow tank, the right triangle inclined surface of the overflow tank allowed the coarse sand with a weight to stay at the bottom, and the fine slurry was from above. The overflow and outflow slurry outlet flows out to avoid turbulence, and use inclined sand outlet guide grooves and staggered inclined plates to ensure that the coarse sand slides back to the sand retrieval tank.
It effectively avoids turbulence during the grinding wheel operation, ensures that the slurry does not entrain coarse sand, improves the quality of the slurry, and slides the deposited coarse sand back to the sand recovery tank through the design of the overflow tank, achieving efficient filtration of the slurry.
