A vertical shaft discharge structure

Abstract

The present invention discloses a vertical shaft discharge structure, wherein a frame is arranged on a slope, and corresponding grid frames are arranged on the frame according to the number of pads, and a horizontal ridge is arranged between each grid frame and the frame; the pad is fixed in the grid frame, and the cross section of the pad is a trapezoid; the height of the ridge is greater than the height of the pad; and a filter grate is arranged above the inclined surface. The advantages of the present invention are: due to the structure of arranging ridges between the frame and the grid frames, finer mineral materials are accumulated in the gaps between the ridges and cover the frame, so that the frame has a buffering effect and is protected from being damaged when being impacted by larger mineral materials; and the height of the ridge is higher than the pad, so the surface of the pad also has a layer of finer mineral materials, which also protects the pad.

Description

Technical Field

[0001] The invention relates to the technical field of mines, in particular to a mineral material filtering and discharging device. Background Art

[0002] After the ore is collected and initially crushed, it needs to be screened through a filter grate. The qualified ore passes through the filter grate and falls onto the pad on the slope, and then slides to the next step, while the unqualified ore is crushed again; since the gaps in the screening grate are large, the ore hits the pad after falling, and the pad and the frame that fixes the pad are very easy to be damaged and need to be replaced and repaired frequently, which not only causes waste, but also consumes a lot of production time and causes a decrease in work efficiency. Summary of the invention

[0003] In order to solve the above technical problems, the purpose of the present invention is to provide a vertical shaft discharge structure, a frame is arranged on the slope, the frame is provided with corresponding grid frames according to the number of pads, and a horizontal support edge is arranged between each grid frame and the frame; the pad is fixed in the grid frame, and the cross section of the pad is trapezoidal; the height of the support edge is greater than the height of the pad; a filter grate is arranged above the slope. A boss is arranged at the lower end of the pad, and a groove is arranged below the grid frame, and the boss is inserted into the groove; the frame and the grid frame are fixed on the slope by anchor bolts.

[0004] The end of the filter grate is fixed on the slope through a bracket.

[0005] The advantages of the present invention are as follows: due to the structure of arranging supporting edges between the frame and the grid frame, finer mineral materials are accumulated in the gaps between the supporting edges and cover the frame, thereby having a buffering effect on the frame and protecting the frame from being damaged when impacted by larger mineral materials; and the height of the supporting edges is higher than the pad, therefore, a layer of finer mineral materials is also provided on the surface of the pad, which also protects the pad. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 It is a structural schematic diagram of the present invention;

[0007] Figure 2 for Figure 1 A-direction view;

[0008] Figure 3 for Figure 2 Schematic diagram of BB cross section. DETAILED DESCRIPTION

[0009] The present invention is described in detail below with reference to the accompanying drawings. As shown in the figure, a frame 2 is arranged on a slope 1, and corresponding grid frames 8 are arranged on the frame 2 according to the number of pads. A horizontal ridge 4 is arranged between each grid frame 8 and the frame 2; a pad 3 is fixed in the grid frame 8, and the cross section of the pad 3 is a trapezoid; the height of the ridge 4 is greater than the height of the pad 3; a filter grate 5 is arranged above the inclined surface. A boss 7 is arranged at the lower end of the pad, and a groove 6 is arranged below the grid frame 8, and the boss 7 is inserted into the groove 6; the frame 2 and the grid frame 8 are fixed on the slope 1 by anchor bolts.

[0010] The end of the filter grate is fixed on the slope through a bracket 9.

Claims

1. A vertical shaft discharge structure, characterized in that: A frame is arranged on the slope, and corresponding grid frames are arranged on the frame according to the number of pads, and a horizontal support edge is arranged between each grid frame and the frame; the pad is fixed in the grid frame, and the cross section of the pad is a trapezoid; the height of the support edge is greater than the height of the pad; Fine mineral materials accumulate in the gaps between the supporting edges and cover the frame, which has a buffering effect on the frame and protects the frame from being damaged when impacted by larger mineral materials.
