A first filter plate 4 is fixedly installed inside the upper mounting frame 3, and a second filter plate 5 is fixedly installed inside the lower mounting frame 3. Fixing units 6 are arranged on the left and right sides of the two mounting frames 3. A discharge port 7 is opened at the bottom of the box body 1. An upper docking plate 8 is fixedly connected to the bottom of the discharge port 7. Clamping parts 9 are arranged on the left and right sides at the bottom of the upper docking plate 8. A lower docking plate 10 is arranged at the bottom of the upper docking plate 8. A collection box 11 is fixedly connected to the bottom of the lower docking plate 10. The fixing unit 6 includes two mounting grooves 61 which are respectively opened on the left and right side walls of the mounting frame 3. Gears 62 are rotatably installed on the rear side walls of the two mounting grooves 61. Telescopic rods 63 are slidably connected to the bottoms of the two mounting grooves 61. Racks 64 are fixedly connected to the tops of the two telescopic rods 63. The two gears 62 are respectively meshed with the two racks 64. Rotating shafts 65 are fixedly connected to the front ends of the two gears 62. The front ends of the two rotating shafts 65 extend to the front end of the mounting frame 3 and are fixedly connected with knobs 66. When in use, large lumps are filtered by the first filter plate 4, medium-sized impurity particles are filtered by the second filter plate 5, and the filtered sand drops into the collection box 11 from the discharge port 7 through the guide plate 14. By squeezing the clamping blocks 94 on both sides, the collection box 11 can be removed as a whole, which is convenient for workers to take out the filtered sand for reuse. By rotating the knob 66, the gear 62 drives the telescopic rod 63 to contract into the mounting groove 61, and the fixing of the mounting frame 3 to the box body 1 can be released, which is convenient for workers to clean and maintain the filter plate and improves work efficiency.

[0023] Furthermore, as Figures 2 - 5As shown in the figure, grooves are provided on the inner walls of the left and right sides of the box body 1. One end of each of the two telescopic rods 63 away from each other penetrates through the outer wall of the mounting frame 3 and is slidably connected to the inside of the groove. The clamping member 9 includes a mounting block 91 and a through groove 92. The mounting block 91 is fixedly connected to the bottom of the upper docking plate 8. The through groove 92 is provided on the top of the lower docking plate 10. The mounting block 91 is slidably connected to the through groove 92. A moving groove 93 is provided on the side of the bottom of the mounting block 91 away from the collection box 11. A clamping block 94 is slidably connected to the inside of the moving groove 93. One end of the clamping block 94 close to the collection box 11 is fixedly connected to a spring 95. The other end of the spring 95 is fixedly connected to the inner wall of the moving groove 93. Two pairs of sliding rods 12 are fixedly connected to the inner wall of the box body 1.

Then the lower docking plate 10 together with the collection box 11 is installed at the bottom of the upper docking plate 8. By squeezing the clamping block 94, when the upper docking plate 8 and the lower docking plate 10 are completely attached, the clamping block 94 pops out of the moving groove 93 under the action of the spring 95 to complete the fixation. Workers pour the sand together with other impurity particles into the box body 1 from the feed port 2, start the air blower 13, filter the larger lumps through the first filter plate 4, filter the medium-sized impurity particles through the second filter plate 5, and the sand falls into the collection box 11 through the discharge port 7 under the action of the guide plate 14.
