Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention comprises the following steps: please refer to fig. 1-3, a concrete sand-stone separator, comprising a box body 1, a feed hopper 4 communicated with the inside of the box body 1 is installed at the top center of the box body 1, a first-stage filter screen 9 and a second-stage filter screen 5 are respectively installed in the box body 1 from top to bottom, a first-stage rotary filter screen 10 is installed on the upper portion of the first-stage filter screen 9 in the box body 1, a second-stage rotary filter screen 6 is installed in the box body 1 and between the first-stage filter screen 9 and the second-stage filter screen 5, a first sliding door 2 parallel to the first-stage filter screen 9 is arranged on one side of the box body 1, a second sliding door 11 parallel to the second-stage filter screen 5 is arranged on the other side of the. The mesh aperture of one-level filter screen 9 is greater than the mesh aperture of second grade filter screen 5, and the mesh aperture of one-level filter screen 9 and second grade filter screen 5 is 10mm and 2mm respectively in this embodiment. The structure of one-level rotary filter screen 10 is the same with second grade rotary filter screen 6, comprises pivot 12 and four filter screen pieces 13 of welding on pivot 12 in rotating installation box 1, and the mesh aperture of filter screen piece 13 on one-level rotary filter screen 10 is greater than the mesh aperture of filter screen piece 13 on second grade rotary filter screen 6. The first sliding door 2 and the second sliding door 11 are identical in structure and are composed of L-shaped sliding rails 7 symmetrically fixed on two sides of a door opening of the box body 1 and a gate 8 connected between the L-shaped sliding rails 7 on the two sides in a sliding mode. The one-level filter screen 9 inclines towards the direction of sliding door 2, and the second grade filter screen 5 inclines towards the direction of sliding door 11, guarantees that the sand or the stone after the separation can be through the natural gliding from sliding door 2 or sliding door 11 roll-off of action of gravity.

The working principle of the invention is as follows:

when in use, the concrete sand separator is arranged near the sedimentation tank and at a lower horizontal position; the concrete-doped water cleaned by the concrete pouring equipment enters from the feed hopper 4, impacts the primary rotary filter screen 10 after entering, so that the primary rotary filter screen 10 rotates, and the mixture of the concrete and the water flowing in can be dispersed instead of flowing down in the form of water columns after the primary rotary filter screen 10 rotates, so that the contact area of the mixture and the primary filter screen 9 is increased, and the mixture is easier to filter. The mixture falls on the first-stage filter screen 9 after being dispersed by the first-stage rotary filter screen 10, stones which are larger than the meshes of the first-stage filter screen 9 and are mixed in the mixture are left on the first-stage filter screen 9, and the stones which are smaller than the meshes of the first-stage filter screen 9 flow into the lower layer; because the first-level filter screen 9 inclines towards the sliding door 2, the filtered stones can move towards the sliding door 2 under the action of gravity and the impact of water. And finally, opening the first sliding door 2 after filtering is finished, and taking out the stones for recycling. In a similar way, the mixture filtered by the first-level filter screen 9 can flow to the second-level rotary filter screen 6 and the second-level filter screen 5 on the next layer, sand in the mixture can be filtered out by the same principle, and the sand is recycled. The filtered wastewater flows to the bottom of the box body 1 and is discharged into the sedimentation tank through a water outlet 3 at the bottom of the box body 1.

In conclusion, the invention filters the mixture of water and concrete when the concrete equipment is cleaned to obtain the sand and the stones, and recycles the sand and the stones to achieve the effects of reducing material consumption and saving construction cost.
