It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0027] like Figure 1 , 2 As shown in Figure 3, this utility model discloses a technical solution: a quartz sand washing and dewatering screen, including a frame 1. Bottom support cylinders 11 are welded or bolted to the four corners of the upper part of the frame 1. The bottom support cylinders 11 on both sides are set at different heights. An inclined support frame 3 is installed on the upper part of the frame 1 via elastic elements 2 mounted on the bottom support cylinders 11. A filter screen 4 is detachably fixed inside the support frame 3 by bolts, facilitating the replacement of the filter screen 4. A feed hopper 5 is longitudinally installed on the lower side of the support frame 3, with the outlet of the feed hopper 5 lower than its closed end, used to discharge the dewatered quartz sand. The bottom support cylinder 11 on the side of the feed hopper 5 is lower than the bottom support cylinder 11 on the side away from the feed hopper 5. Top support cylinders 12 are bolted to the four corners of the support frame 3. A telescopic spring, as an elastic element 2, is installed between the bottom support cylinders 11 and the top support cylinders 12, causing the support frame 3 to be installed inclined on the frame 1. Baffles 6 are vertically welded to the other three side walls of the support frame 3. Figure 4As shown, the inner walls of the two opposing baffles 6 are vertically welded with first insert plates 13. The two first insert plates 13 are provided with first slots 14 on opposite sides. The limiting plate 7 is inserted into the first insert plate 13 through the first slots 14, dividing the upper side of the filter screen 4 into a dewatering chamber and a feeding chamber, which facilitates the dewatering of the quartz sand.

[0028] like Figure 5 , 6 As shown, a water collection assembly 8 is installed on the frame 1 below the dehydration chamber. The water collection assembly 8 includes a water collection hopper 15 and a water blocking frame 16. The water collection hopper 15 is fixedly installed on the frame 1 by bolts. The water blocking frame 16 is welded or bolted to the bottom of the water collection hopper 15. The water blocking frame 16 and the water collection hopper 15 are connected. The front and rear opposite side walls of the water blocking frame 16 are provided with third slots 18. The left and right opposite side walls of the water blocking frame 16 are welded with longitudinally arranged second insert plates 19. The two second insert plates 19 are provided with second slots 20 on opposite sides. The water blocking plate 17 is inserted from the front third slot 18, passes through the second slot 20 and extends out from the other side third slot 18.

[0029] Specifically, a vibration motor 10 is bolted to the higher side of the support frame 3 via a support plate 9, and a ladder 21 is welded to one side of the frame 1.

[0030] The working process of this embodiment is as follows: The washed quartz sand is poured into the dewatering chamber on the higher side of the support frame 3. The vibration motor 10 is started, and the support frame 3 vibrates under the action of the vibration motor 10 and the elastic element 2. Under the action of vibration, the quartz sand rolls back and forth in the feeding chamber. During the rolling process, the water on the surface of the quartz sand falls into the water collection hopper 15 through the filter screen 4. When the water in the water collection hopper 15 reaches a certain amount, the water blocking plate 17 is pulled out, and the water is discharged from the water blocking frame 16. After dewatering, the limiting plate between the feeding chamber and the dewatering chamber is pulled out, and the quartz sand moves along the filter screen 4 to the lower side of the feeding chamber and enters the feeding chamber. Then it is discharged through the feeding hopper 5 to the subsequent collection equipment.
