Embodiment Construction
[0011] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0012] Such as figure 1 As shown, the sandstone double-layer push-pull guide plate of the present embodiment is installed in the sedimentation bucket, and the guide plate includes upper and lower layers, which are respectively the upper guide plate 1 and the lower guide plate 2, and the upper guide plate 1 and the lower guide plate There is a distance 3 between the guide plates 2, the upper end of the upper guide plate 1 is fixed on the bracket 4, the upper end of the lower guide plate 2 is mounted on the bracket 4 through the movement, and the drive for pushing the lower guide plate 2 to move up and down is installed on the bracket 4 device; the upper guide plate 1 is evenly distributed with upper filter holes 10, the lower guide plate 2 is evenly distributed with lower filter holes 20, the aperture of the upper filter hole 10 is greater th...

The invention relates to a sandstone dual-layer push-and-pull guide plate which is arranged in a sedimentation hopper and comprises an upper layer and a lower layer, namely an upper guide plate and a lower guide plate, wherein a spacing is reserved between the upper guide plate and the lower guide plate; the upper end of the upper guide plate is fixedly arranged on a bracket, the upper end of the lower guide plate is movably arranged on the bracket in a penetrating manner, and the bracket is provided with a driving device capable of pushing the lower guide plate to move up and down; upper filtration holes are uniformly distributed in the upper guide plate, lower filtration holes are uniformly distributed in the lower guide plate, the pore diameter of the upper filtration holes is greater than that of the lower filtration holes, and the upper filtration holes and the lower filtration holes are distributed in a staggered manner. The guide plate is of a dual-layer structure; double filtration is performed on sandstone, and the upper and lower filtration holes are different in thickness; during filtration, the lower guide plate is pushed to move up and down, so that push-and-pull filtration on the sandstone during secondary filtration is realized, blockage of the filtration holes is avoided, and the filtration effect and the filtration efficiency are improved.
Description
technical field [0001] The invention relates to a sand-water separator, in particular to a double-layer push-pull guide plate for sand and gravel. Background technique [0002] The sand-water separator is composed of a feed sedimentation hopper, a screw shaft, a screw groove, a support frame and a driving device. The sand-water mixture enters the feeding settling hopper and settles through the inclined plate, and the water is discharged from the overflow tank. The screw shaft lifts the settling sand out of the water surface and discharges it. The existing sloping plate needs to circulate and settle for many times when precipitating the sand-water mixture, resulting in low efficiency; moreover, the sloping plate is fixed in the sedimentation bucket, and its filter holes are easily blocked. Contents of the invention [0003] In view of the above-mentioned shortcomings existing in the existing sand-water separator, the applicant conducts research and design, and provides a d...
