Description

Technical Field

[0001] The utility model relates to a mine transportation device. Background Art

[0002] Mine hoisting and transportation devices are indispensable equipment in the mining industry, and are mainly responsible for transporting ore between equipment. Existing mine hoisting and transportation devices mostly use belt conveyors, and are installed in outdoor transportation channels built in board houses. This structure meets the transportation needs of mines to a certain extent, but there are many problems in the actual application process:

[0003] First, the building materials of the board house passage are mostly light materials such as color steel plates and rock wool boards, and their load-bearing capacity is limited. The belt conveyor itself is heavy, and the ore it transports is also quite heavy, which may cause the board house to deform or even collapse, seriously affecting transportation safety.

[0004] Second, the sealing performance of the board house passage is poor, which cannot effectively prevent the erosion of ore by external factors such as rain and dust, thereby reducing the quality of the ore.

[0005] 3. The fire-proof performance of the board house passage is poor. Once a fire occurs, the fire will spread easily.

[0006] On the other hand, the return conveyor belt at the bottom of the belt conveyor is sticky with slurry that has not fallen into the next equipment. During the return process, the slurry will fall to the bottom of the belt conveyor, which not only causes waste, but also requires staff to clean it frequently, which is labor-intensive and poses a safety hazard. Utility Model Content

[0007] The utility model proposes a modular mine hoisting and transporting device based on a container, the purpose of which is: 1. to solve the problems of poor load-bearing capacity, poor sealing performance and poor fireproof performance of the transport channel of the existing mine hoisting and transporting device. 2. to solve the problem of difficulty in cleaning the slurry at the bottom of the belt conveyor.

[0013] As a further improvement of the container-based modular mine hoisting and transportation device: the mud storage tank is a stainless steel tank with a U-shaped cross-section.

[0014] As a further improvement of the container-based modular mine hoisting and transportation device: the jet cleaning devices are multiple groups, which are arranged at intervals along the length direction of the mud storage tank.

[0031] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0032] like Figure 1 A modular mine lifting and transportation device based on a container includes a transportation channel and a belt conveyor 3 installed inside the transportation channel. The belt conveyor 3 can be one group or more than two groups. In this embodiment, there are two groups, and the discharge port of the belt conveyor 3 of the previous stage is located above the drop area of ​​the belt conveyor 3 of the next stage.

[0033] The transport channel is formed by connecting a plurality of containers 4 end to end. The containers 4 are made of metal and have openings at both ends.

[0034] like Figure 5, adjacent containers 4 are connected to each other through connecting plates 4-1, bolts and nuts. Specifically, multiple groups of connecting plates 4-1 are welded on the end side wall plates of the container 4, and through holes are opened on the connecting plates 4-1. The connecting plates 4-1 of adjacent containers 4 correspond to each other and are grouped. Bolts pass through the through holes on two corresponding connecting plates 4-1 in sequence and are connected with nuts. For transportation channels that are put into use for a long time, the connection strength between adjacent containers 4 can also be improved by direct welding.

[0035] like Figure 1 The transport channel is inclined and installed on the ground through a column 1 at the bottom.

[0036] Furthermore, the transport channel is also provided with a mud storage tank 2 arranged at the bottom of the belt conveyor 3. Figure 2 and 3 The mud storage tank 2 is a stainless steel tank with a U-shaped cross section. A jet cleaning device is installed on the inner wall of the mud storage tank 2. Figure 1 The jet cleaning devices are multiple groups, which are arranged at intervals along the length direction of the mud storage tank 2. Each group of the jet cleaning devices includes a cleaning water nozzle 6 and a compressed gas nozzle 7, which spray toward the slurry storage tank 5 or toward the conveyor belt 2-2 at the bottom of the belt conveyor 3. For the cleaning water nozzle 6 and the compressed gas nozzle 7 spraying toward the slurry storage tank 5, the cleaning water nozzle 6 is located above the compressed gas nozzle 7.

[0037] The cleaning water nozzle 6 is connected to the cleaning water pipeline, and a water stop valve 8 is provided on the cleaning water pipeline. The compressed gas nozzle 7 is connected to the compressed gas pipeline, and a gas stop valve 9 is provided on the compressed gas pipeline. Through the corresponding stop valves, high-pressure water and compressed air can be controlled to be sprayed simultaneously or separately. For example, when the water content of the slurry at the bottom of the conveyor belt 2-2 is high, compressed gas can be used for spraying alone.

[0038] A slurry storage pool 5 is provided on the outer side of the bottom of the transport channel, and the lower end of the mud storage tank 2 is located above the slurry storage pool 5 .

[0039] Further, such as Figure 1 and 4 The belt conveyor 3 includes a frame, a driving roller 2-1 installed at the upper end of the frame, a driven roller installed at the lower end of the frame, a conveyor belt 2-2 connected between the driving roller 2-1 and the driven roller, and a roller installed on the frame for supporting the conveyor belt 2-2.

[0040] The gold ore produced in the Jiaodong gold-rich area has hard ore, large specific weight, and high scale lifting tonnage. The existing lifting system often runs off-track. Figure 4In this embodiment, an annular flange 2-1-1 is provided at both ends of the roller body of the driving roller 2-1. Furthermore, a transition fillet 2-1-2 is provided at the junction of the flange 2-1-1 and the roller body. The flange 2-1-1 and the transition fillet 2-1-2 can effectively prevent the conveyor belt 2-2 from deviating.

[0041] Furthermore, the roller body is provided with a cross friction pattern to increase friction and avoid slipping.

[0042] During construction, the container 4 is first docked to form a transport channel, then the column 1 is installed, then the mud storage tank 2 is installed, and then the belt conveyor 3 is installed. The slurry storage tank 5 can be constructed synchronously.

[0043] During transportation, the ore and slurry fall to the bottom of the belt conveyor 3 and move upward with the conveyor belt 2-2. Most of the ore and slurry enter the next device from the top, and a small amount of slurry sticks to the conveyor belt 2-2 and reaches the bottom of the belt conveyor 3 with the return conveyor belt 2-2. At this time, the jet cleaning device can blow the residual slurry on the conveyor belt 2-2 and the slurry that has fallen into the mud storage tank 2 toward the slurry storage tank 5, and finally the residual slurry and cleaning water are collected in the slurry storage tank 5 for recycling.

[0044] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. The scope of the present invention is defined by the claims rather than the above description.
