Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Fig. 1 is the embodiment of the utility model provides a tailing grit recovery unit schematic structure, it is right to combine fig. 1 below the utility model provides a tailing grit recovery unit carries out detailed description.

As shown in fig. 1, the tailings gravel recovery device mainly comprises a spiral feeding cylinder 1 and a separation box 2.

Specifically, the spiral feeding cylinder 1 comprises a motor 11, an outer cylinder 12, a rotating shaft 13 and spiral blades 14, wherein the motor 11 is installed at one end of the spiral feeding cylinder, is connected with the rotating shaft 13 and is used for driving the rotating shaft 13 to rotate, and the spiral blades 14 are uniformly and spirally arranged on the outer peripheral surface of the rotating shaft 13. Feed inlet 15 has been seted up to the side of outer barrel 12 one end, and another port communicates with separator box 2, follows feed inlet 15 back, carries out preliminary separation to the tailing grit through helical blade 14's rotation, then enters into rear end separator box 2. The tailing sand and stone are primarily separated through the spiral feeding cylinder 1, especially the sand and stone with small particle size are separated from the sand and stone with large particle size, the problem that the separation is not thorough due to the entrainment effect of the subsequent separation is avoided, and the subsequent separation efficiency is improved.

The separation box 2 is internally provided with a first separation plate 3 and a second separation plate 4 in an inclined manner, the second separation plate 4 is positioned below the first separation plate 3, the inclined directions of the first separation plate 3 and the second separation plate 4 are opposite, and the aperture of a separation hole of the second separation plate 4 is smaller than that of a separation hole of the first separation plate 3. The separator box 2 is provided with a sand outlet 5, and the sand outlet 5 is respectively positioned at the lower end of the first separator plate 3 and the second separator plate 4. The bottom of the separation box 2 is provided with a waste water discharge port 6. The first separating plate 3 and the second separating plate 4 are obliquely arranged, and a sand outlet 5 is formed in the separating box 2 at the oblique bottom end position, so that sand left on the separating box by filtering slides to the sand outlet 5, and flows out of the separating box 2 from the sand outlet 5; the first separating plate 3 and the second separating plate 4 are arranged up and down, and the aperture of the separating hole of the second separating plate 4 is smaller than that of the first separating hole plate, so that larger sand and stone are intercepted by the first separating plate 3, and smaller sand and stone are intercepted by the second separating plate 4, and thus, sand and stone wastewater can be separated more thoroughly and efficiently; the grit waste water material is received at first on 3 upper portions of first separator plate, also has more tiny grit to enter into second separator plate 4, and the slope opposite direction of first separator plate 3 and second separator plate 4, and the lower one end of second separator plate 4 is just more fallen on to tiny grit like this, conveniently flows out from grit export 5. Because the gravity of the fine sand and stone is small, the fluidity on the separating plate is poor, so that most of the fine sand and stone cannot flow from top to bottom, and more sand and stone can flow out more conveniently close to the outlet. The mud and water flowing down after the sand and stone recovery enters the bottom of the separation box 2 and is discharged through a waste water discharge port 6.

Because the tailings are solid-liquid mixtures, the separated sand carries more water, which is inconvenient for subsequent storage and utilization, and therefore, the sand needs to be dried. In order to solve the above technical problem, the embodiment of the present application provides a preferred implementation manner, a conveyor belt 7 is disposed below the outside of the sand outlet 5, the conveyor belt 7 passes through a drying chamber 8, and the drying chamber 8 is installed near the sand outlet 5. Grit enters into conveyer belt 7 from grit export 5 carrying out separator box 2 back, in carrying to the drying chamber 8, drying chamber 8 is close to grit export 5 and also can avoid moisture to flow down at conveyer belt 7 transportation in-process, causes the pollution.
