Description

Technical Field

[0001] The utility model relates to the technical field of vertical shaft bottom powder ore processing, in particular to a vertical shaft bottom powder ore processing device. Background Art

[0002] Underground mining is an important method for obtaining mineral resources. The development methods of underground mining include horizontal tunnels, inclined shafts and vertical shafts. The collection and treatment of fine ore at the bottom of horizontal tunnels and inclined shafts during hoisting is relatively simpler than that of vertical shafts. Mines developed and hoisted by vertical shafts are troubled by the difficulty in collecting and treating fine ore at the bottom of the shaft. The design of fine ore at the bottom of the vertical shaft in the mining design manual only uses a primary sedimentation tank for treatment. At present, most mines treat fine ore at the bottom of the vertical shaft according to the mining design manual. The existing treatment of fine ore at the bottom of the vertical shaft is a rough and simple treatment device. When the device is in use, ore and waste rock are mixed. The generation and properties of fine ore are not handled according to different situations, and fine treatment cannot be carried out, resulting in the loss of some useful ore. In addition, several working days are required every month to process the fine ore, which has a great impact on production.

[0003] For this purpose, we design a powder ore processing device at the bottom of a vertical shaft. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for processing powder ore at the bottom of a vertical shaft, comprising a sedimentation box, which is installed at the bottom of the vertical shaft. The sedimentation box is composed of a first box body, a second box body and a third box body arranged side by side. The top of the first box body is connected to the top of the second box body by a first water inlet pipe, and the top of the second box body is connected to the top of the third box body by a second water inlet pipe. The bottoms of the three boxes are all provided with ore unloading ports, a collecting tray is provided above the first box body, the collecting tray is fixedly installed on the wall of the vertical shaft, the bottom outlet of the collecting tray is connected to the first box body by a pipe, and the top of the third box body is provided with a water outlet pipe.

[0006] Preferably, a bucket bracket is installed on the shaft wall of the vertical shaft, the bucket bracket is located above the collecting plate, a bucket is installed on the bucket bracket, rollers are installed on the shaft wall of the vertical shaft, a funnel trough is installed on the rollers, and the funnel trough is located above the bucket.

[0007] Preferably, the diameters of the first water inlet pipe, the second water inlet pipe and the water outlet pipe are increased step by step, and the water outlet elevations of the pipes are gradually increased.

[0008] Preferably, the skip is a shaft skip.

[0009] Preferably, the funnel trough is a retractable funnel trough, and a hydraulic rod for controlling its retraction and extension is installed on the funnel trough.

[0010] Compared with the prior art, the utility model provides a device for processing fine ore at the bottom of a vertical shaft, which has the following beneficial effects:

[0011] The fine ore processing device at the bottom of the vertical shaft can collect fine ore by setting a sedimentation box and a collecting tray. At the same time, useful minerals and waste ore can be separated immediately, and useful minerals can be effectively recovered, which reduces the time for centralized processing of fine ore at the bottom of the shaft, indirectly increases the time for transporting ore from the shaft, and has a positive impact on production. Moreover, the fine ore is not processed on the ground, and the fine ore will not pollute the shaft bottom tunnel, which brings an essential improvement to safe production.

DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

The powder ore and turbid water falling in the well can be collected by the collecting plate 2 and then enter the sedimentation box 1. An outlet pipe 5 is arranged on the top of the third box body 1-3. The sedimentation box 1 and the inlet and outlet pipes form a set of tubular multi-stage sedimentation devices for graded sedimentation. The diameters of the first inlet pipe 3, the second inlet pipe 4 and the outlet pipe 5 are gradually increased, and the outlet elevation of the pipe is gradually increased. The elevation of the outlet pipe 5 is lower than the outlet elevation of the collecting plate 2, ensuring that the wastewater entering the sedimentation box 1 has enough sedimentation time. The three boxes separate the useful ore and the waste rock, thereby recovering the useful ore. When the sedimentation box 1 is settled to 2 / 3 of the effective volume, the ore is unloaded from the unloading port 6 to the transportation equipment in the horizontal tunnel.

[0017] See also Figure 1 A skip bracket 7 is installed on the wall of the shaft 10, and the skip bracket 7 is located above the collecting plate 2. A skip 8 is installed on the skip bracket 7. Rollers are installed on the wall of the shaft 10, and a funnel trough 9 is installed on the rollers. The funnel trough 9 is located above the skip 8. The skip 8 adopts a shaft skip, and the funnel trough 9 adopts a retractable funnel trough. A hydraulic rod for controlling its retraction is installed on the funnel trough 9. When working, the inlet of the funnel trough 9 is connected to the outlet of the ore distribution metering funnel at the upper part of the shaft 10, and a container is installed on the ore unloading platform at the upper part of the shaft 10. The volume measuring instrument is used to measure the instantaneous volume of the skip 8 and transmit the measured data to the ore-discharging control console at the bottom of the shaft, and then the ore-discharging control console issues a command to the ore-feeding system at the bottom of the shaft 10, so that the ore-feeding amount of the ore-discharging metering funnel is instantly matched with the volume of the skip 8. A distance meter is installed below the ore-discharging metering funnel to measure the distance between the ore-discharging metering funnel and the skip 8, and transmit the measured data to the ore-discharging control console, and then the ore-discharging control console adjusts the length of the funnel slot 9 by controlling the hydraulic rod to make the outlet of the funnel slot 9 close to the entrance of the skip 8.

[0018] The working principle and use process of the utility model are as follows: when the powder ore processing device at the bottom of the vertical shaft is used, the turbid water and powder ore falling in the vertical shaft 10 can be collected by the collecting plate 2 and enter the first box 1-1, and then the heavy objects are precipitated, and the supernatant enters the second box 1-2 through the first water inlet pipe 3. Then, according to the same principle, the clearer supernatant enters the third box 1-3 through the second water inlet pipe 4, and finally the supernatant is discharged from the outlet pipe 5. The ore, waste ore and mud containing no useful minerals are respectively precipitated in the three boxes. The ore unloading ports 6 of the three boxes can be opened to remove the ore, waste ore and mud containing no useful minerals in the sedimentation box 1.
