[0025] In the present utility model, it should be noted that the circulating spraying assembly includes a water pump 1, which is fixed to one side outer wall of a shell 5 by bolts. Two brackets 2 are fixed to one side outer wall of the shell 5 by bolts. A connecting pipe 3 is connected between the two brackets 2. A discharge pipe 4 is connected and fixed to the top of the side of the shell 5. One end of the discharge pipe 4 passes through the shell 5 and is connected and fixed to a spray rack 18. The water pump 1 is started to extract the cleaning liquid of the shell 5 and enter the connecting pipe 3 through the feeding pipe 7. At this time, the filter plate 8 filters the impurities in the cleaning liquid, and then the filtered cleaning liquid enters the discharge pipe 4 through the connecting pipe 3, and then is sprayed onto the silicon wafer through the spray rack 18, so that the silicon wafer is rinsed. The two ends of the feeding pipe 7 are respectively connected to the connecting pipe 3 and the discharge pipe 4.

A handle is bonded to one side of the slide 12, and a plurality of spaced placement racks are fixed on the inner wall of the shell 5 by bolts. The cleaning liquid flows back into the bottom of the shell 5 through the gaps between the placement racks, so that the device filters and pumps water again, and the cycle is repeated, so that the silicon wafers are efficiently rinsed.
[0026] Working principle: when it is necessary to clean the silicon wafers on the placement rack, first start the water pump 1 to extract the cleaning liquid from the shell 5 and allow it to enter the connecting pipe 3 through the feed pipe 7. At this time, the filter plate 8 filters the impurities in the cleaning liquid, and then the filtered cleaning liquid enters the discharge pipe 4 through the connecting pipe 3, and then is sprayed onto the silicon wafers through the spray rack 18, thereby flushing the silicon wafers. When it is necessary to disassemble and clean the filter plate 8, pull the slide 12 to move it outward along the fixed rod 11, and the first spring 10 extends until the slide 12 moves out of the socket 17. At this time, the fixed block 16 loses its restriction, and the second spring 13 rebounds and extends, so that the slider 15 pushes the fixed block 16 to move upward along the slide groove 9, and then the staff pulls the filter plate 8 until the fixed block 16 is completely out of the slide groove 9, thereby completing the disassembly of the filter plate 8, which is convenient for subsequent cleaning.
