Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, and more specifically, to a ore discharge machine chamber structure. Background Technology

[0002] In underground mines, the general process for transporting ore is as follows: mine car (truck) — unloading station — ore pass — ore bin — ore discharge chamber — conveyor belt (mine car) — skip (cage), among which the ore discharge chamber is an indispensable link. In the ore discharge chamber, the vibrating ore discharge machine chamber is an ideal device for discharging, feeding, or loading ore and other materials.

[0003] Vibratory ore feeders are widely used in underground mines. The design, layout, and construction of vibratory ore feeder chambers are relatively mature. The existing structures of vibratory ore feeder chambers are as follows: Figures 1 to 3 As shown, it includes a ore bin 1', a ore bin lower opening 2' located below the ore bin, and a ore feeding machine chamber 5' located below the ore bin lower opening 2'. Normally, one ore bin corresponds to only one ore feeding machine chamber, and only one vibrating ore feeding machine 6 is arranged in one ore feeding machine chamber 5'. A maintenance platform 7' for inspecting the vibrating ore feeding machine 6 and a platform ladder 9' for workers to climb to the maintenance platform 7' are provided in the ore feeding machine chamber 5'.

[0004] In actual mining operations, as mining projects continue to develop and the scale of mining increases, a single ore feeder cannot meet the demand. Therefore, it is necessary to set up multiple ore bins plus vibrating ore feeder chambers. Obviously, this method of expanding ore bins in the later stages involves a large amount of engineering work and seriously affects the construction period. In addition, some mining operations are divided into early-stage and late-stage projects, and the ore feeder equipment needs to be able to serve both stages. Obviously, the existing setup of setting up a single ore feeder in the ore bin cannot meet the needs.

[0005] Based on the above technical requirements, there is an urgent need for a ore discharge chamber structure that can meet the needs of increasingly larger mining scales and can also take into account the pre- and post-processing of the project. Summary of the Invention

[0006] In view of the above problems, the purpose of this invention is to provide a ore feeding machine chamber structure to solve the problem that existing vibratory ore feeding machine chambers cannot meet the requirements due to the fact that only a single ore feeding machine is installed.

[0007] The ore discharge machine chamber structure provided by this invention includes a primary chamber and a secondary chamber located below the ore bin. A first ore bin lower opening and a second ore bin lower opening are provided at the bottom of the ore bin. The first ore bin lower opening is connected to the primary chamber, and the second ore bin lower opening is connected to the secondary chamber.

[0008] A first-stage ore discharge machine is installed in the first-stage chamber, corresponding to the lower opening of the first ore bin, and a second-stage ore discharge machine is installed in the second-stage chamber, corresponding to the lower opening of the second ore bin.

[0009] Furthermore, in a preferred embodiment, at least two of the first-phase mining machines are installed in the first-phase chamber, and at least one of the second-phase mining machines is installed in the second-phase chamber.

[0010] Furthermore, a preferred embodiment is that a first lower beam is provided inside the lower opening of the first ore bin, and a second lower beam is provided inside the lower opening of the second ore bin; wherein,

[0012] Furthermore, a preferred embodiment is that the elevation of the lower opening of the first ore bin is lower than the elevation of the lower opening of the second ore bin.

[0013] Furthermore, a preferred embodiment is that the distance between the centerline of the lower opening of the first ore bin and the centerline of the ore bin is equal to the distance between the centerline of the lower opening of the second ore bin and the centerline of the ore bin.

[0014] In addition, a preferred embodiment is that the first-phase ore discharge machine is located at the upper part of the first-phase chamber, and a first-phase maintenance platform corresponding to the first-phase ore discharge machine is located in the middle of the first-phase chamber.

[0015] The second-phase ore discharge machine is located at the upper part of the second-phase chamber, and a second-phase maintenance platform corresponding to the second-phase ore discharge machine is located in the middle of the second-phase chamber.

[0016] In addition, a preferred embodiment is to lay a first-phase ore conveyor belt at the bottom of the first-phase chamber, corresponding to the vertical position of the first-phase ore feeder;

[0017] A second-phase ore conveyor belt, corresponding to the vertical position of the second-phase ore feeder, is laid at the bottom of the second-phase chamber.

[0018] Furthermore, a preferred embodiment is to install a first-phase platform ladder on the first-phase maintenance platform and a second-phase platform ladder on the second-phase maintenance platform.

[0019] In addition, a preferred option is to provide a pedestrian passageway inside the first-phase tunnel.

[0020] Furthermore, a preferred embodiment is that the length of the first-stage chamber is longer than the length of the second-stage chamber, and the height of the first-stage chamber is greater than the height of the second-stage chamber.

[0021] Compared with the prior art, the ore discharge chamber structure according to the present invention has the following advantages:

[0022] The ore feeding machine chamber structure provided by this invention can meet the needs of different ore feeding directions before and after the project by setting two chambers (a first-stage chamber and a second-stage chamber) under the ore bin; without increasing the ore bin or other engineering works, the needs of the corresponding project scale can be met simply by adding equipment (such as an ore feeding machine); in addition, the overall system structure of the ore feeding machine chamber structure provided by this invention is simple, which can effectively save engineering work, save costs, and improve efficiency.

[0035] Figure 4 The diagram shows a top cross-sectional view of the ore discharge chamber structure provided by the present invention. Figure 5 It shows Figure 6 The diagram shows a cross-sectional view of the ore discharge chamber structure provided by the present invention at position II-II; Figure 6 It shows Figure 4 The diagram shows a cross-sectional view of the ore discharge chamber structure provided by the present invention at position III-III.

[0036] Combination Figures 4 to 6As shown in the figure, the ore discharge chamber structure provided by the present invention includes an ore discharge chamber located below a ore bin for storing ore (or other materials) for discharging, feeding or loading ore. A ore bin lower opening is provided at the bottom of the ore bin for connecting the ore bin and the ore discharge chamber. The material or ore in the ore bin enters the ore discharge chamber through the ore bin lower opening for discharging, feeding or loading.

[0037] Specifically, the ore discharge chamber includes a first-phase chamber 5 and a second-phase chamber 10, and the lower opening of the ore bin includes a first ore bin lower opening 2 and a second ore bin lower opening 3; wherein the first ore bin lower opening 2 is connected to the first-phase chamber 5, and the second ore bin lower opening 3 is connected to the second-phase chamber 10.

[0038] More specifically, to enable the ore discharge chamber to discharge, feed, or load materials or ore from the ore bin, a primary ore discharge machine 6 corresponding to the lower opening 2 of the first ore bin is installed in the primary chamber 5, and a secondary ore discharge machine 11 corresponding to the lower opening 3 of the second ore bin is installed in the secondary chamber 10. In actual use, the ore bin distributes materials or ore to the lower opening of the ore bin. After the materials or ore enter the ore discharge chamber (including the primary chamber 5 and the secondary chamber 10) through the lower opening of the ore bin (including the lower opening 2 of the first ore bin and the lower opening 3 of the second ore bin), they will fall precisely onto the primary ore discharge machine 6 or the secondary ore discharge machine 11, and be discharged, fed, or loaded by the primary ore discharge machine 6 or the secondary ore discharge machine 11.

[0039] It should be noted that, in order to ensure the efficiency of ore discharge, the first-phase chamber 5 and the second-phase chamber 10 are mainly set up according to the needs of the mine's near-term and long-term projects. Among them, the ore discharge volume of the first-phase project (corresponding to the mine's near-term project) is relatively large, and at least two ore discharge machines 6 need to be set up in the first-phase chamber 5 (usually two machines are set up). The ore discharge volume of the second-phase project (corresponding to the mine's long-term project) is relatively small, and at least one machine needs to be set up in the second-phase chamber 10 (usually one machine is set up). Furthermore, since the first-stage chamber 5 is the equipment that undertakes the main ore discharge function in the mine, the length and height of the chamber are usually set to be larger. The length of the first-stage chamber 5 needs to be longer than the length of the second-stage chamber 10, and the height of the first-stage chamber 5 needs to be higher than the height of the second-stage chamber 10. In addition, since the second-stage chamber 10 also needs to be connected to the first-stage chamber 5, the support of the first-stage chamber 5 needs to be considered to be more robust and safe.

[0040] Specifically, the first-stage ore feeder 6 or the second-stage ore feeder 11 is usually a vibrating ore feeder, and it is installed on the upper part of the first-stage chamber 5 or the second-stage chamber 10 by means of suspension. By using the suspension method to set the first-stage ore feeder 6 or the second-stage ore feeder 11 on the upper part of the first-stage chamber 5 or the second-stage chamber 10, it is easier for the first-stage ore feeder 6 or the second-stage ore feeder 11 to feed ore to the belt or mine car.

[0041] It should also be noted that the lower opening of the ore bin mainly serves as a connecting link between the upper and lower parts. The upper part connects with the ore bin and distributes the ore or materials to the ore discharge machines in each chamber. In the actual ore discharge process, because the upper part of the lower opening of the ore bin bears the ore from the ore bin and spans across the straight walls on both sides of the ore discharge machine chamber, the lower opening of the ore bin is subjected to very large forces, which can easily lead to damage to the lower opening of the ore bin.

[0042] To solve the aforementioned technical problems, a lower beam 4 can be installed inside the lower opening of the ore bin. Specifically, a first lower beam is installed inside the first lower opening 2 of the ore bin, and a second lower beam is installed inside the second lower opening 3 of the ore bin. The first lower beam divides the first lower opening 2 of the ore bin into at least two first lower openings, each corresponding to the upper or lower position of the corresponding first-phase ore feeding machine 6. Installing the lower beam 4 effectively improves the strength of the lower opening of the ore bin, preventing damage during ore feeding.

[0043] Furthermore, to ensure that the ore is evenly distributed to the lower openings of each ore bin, the distance between the centerline of the ore bin and the centerline of each ore bin's lower opening can be set to approximately equal distances (i.e., the distance between the centerline of the first ore bin's lower opening 2 and the centerline of the ore bin itself is equal to the distance between the centerline of the second ore bin's lower opening 3 and the centerline of the ore bin itself). This arrangement also facilitates the rational stress distribution of the chamber structure. However, since the first-phase chamber 5 receives most of the ore from the ore bins, the elevation of the first ore bin's lower opening 2 can be set lower than the elevation of the second ore bin's lower opening 3. This setting allows most of the ore to be lowered into the first ore bin's lower opening 2.

[0044] It should be noted that the first-phase chamber 5 is divided into three spaces from top to bottom: upper, middle and bottom. The first-phase ore feeder 6 is located in the upper part of the first-phase chamber 5. The first-phase maintenance platform 7, corresponding to the first-phase ore feeder 6, is located in the middle part of the first-phase chamber 5. The first-phase ore conveyor belt (not shown in the figure) is laid at the bottom of the first-phase chamber 5, corresponding to the upper and lower positions of the first-phase ore feeder 6. The first-phase maintenance platform 7 is used by workers to maintain the first-phase ore feeder 6, and the first-phase ore conveyor belt is used to transport the ore fed by the first-phase ore feeder 6. Similarly, the second-stage chamber 10 is divided into an upper part, a middle part, and a bottom part from top to bottom. The second-stage ore feeder 11 is located in the upper part of the second-stage chamber 10. A second-stage maintenance platform 12 corresponding to the second-stage ore feeder 11 is located in the middle part of the second-stage chamber 10. A second-stage ore conveyor belt (not shown in the figure) corresponding to the upper and lower positions of the second-stage ore feeder 11 is laid at the bottom of the second-stage chamber 10. The second-stage maintenance platform 12 is used by workers to maintain the second-stage ore feeder 11, and the second-stage ore conveyor belt is used to transport the ore feeder of the second-stage ore feeder 11.

[0045] In addition, to ensure that staff can move between Phase I chamber 5 and Phase II chamber 10, pedestrian walkways 8 are provided in both Phase I chamber 5 and Phase II chamber 10; and to facilitate staff to quickly reach Phase I maintenance platform 7 and Phase II maintenance platform 12, a Phase I platform ladder 9 is provided on Phase I maintenance platform 7, and a Phase II platform ladder 13 is provided on Phase II maintenance platform 12.

[0046] As can be seen from the above specific embodiments, the ore discharge machine chamber structure provided by the present invention has at least the following advantages:

[0047] 1. By centrally arranging the chamber space and rationally setting the distance and size of the ore discharge openings, the necessary installation and maintenance space can be provided for each ore discharge machine, and the ore discharge direction of each ore discharge machine can be guaranteed to be different;

[0048] 2. It can meet the mine's short-term and long-term ore discharge needs and ensure that the amount of ore discharged from each discharge point is relatively equal;

[0049] 3. The overall system structure of the ore discharge machine chamber provided by the present invention is simple and can ensure the stability and safety of the chamber structure.

[0050] As per the above reference Figures 4 to 6 The ore discharge chamber structure according to the present invention is described by way of example. However, those skilled in the art should understand that various modifications can be made to the ore discharge chamber structure proposed in the present invention without departing from the scope of the invention. Therefore, the scope of protection of the present invention should be determined by the contents of the appended claims.
