Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing device technology, and more specifically, to a vertical mixing device and a mine filling equipment. Background Technology
[0002] Mine backfilling systems typically consist of a metering and supply system for aggregates, cementitious materials, and backfill water, a mixing system, and an automatic control system. The mixing system is crucial in determining backfill quality, and vertical mixing units are currently widely used as the main mixing equipment in the industry. However, practical operation has revealed that traditional vertical mixing units require a significant amount of time for cleaning after each operation, and the cleaning effect is poor. This can also lead to the backfill material solidifying on the inner wall of the mixer. Operators need to manually remove the solidified backfill material from the inside weekly, which not only increases the labor intensity of workers but also significantly increases the system's operation and maintenance costs. Utility Model Content
[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a vertical stirring device that can reduce the difficulty of cleaning it.
[0004] This application also provides a mine filling device.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, this application provides a vertical stirring device having a height direction. The vertical stirring device includes: a stirring assembly having a stirring chamber; multiple spraying assemblies, each of which is disposed within the stirring chamber and spaced apart along the height direction; and a supply assembly including a high-pressure water supply pipeline, multiple connecting pipelines, and multiple flow regulating valves. One end of each connecting pipeline is connected to the high-pressure water supply pipeline, and the other end of each connecting pipeline is connected to one of the spraying assemblies. Each connecting pipeline is provided with one flow regulating valve.
[0007] In an optional embodiment, the plurality of spray assemblies include a first spray assembly and a second spray assembly, wherein the first spray assembly is disposed near the top of the mixing chamber and the second spray assembly is disposed near the bottom of the mixing chamber.
[0008] In an optional embodiment, the supply component further includes a high-pressure air supply pipeline and an air volume regulating valve. The high-pressure air supply pipeline is connected to the connecting pipeline that is connected to the second spray component, and the air volume regulating valve is disposed on the high-pressure air supply pipeline.
[0009] In an optional embodiment, the spray assembly includes a spray pipe and a plurality of spray elements. The spray pipe is connected to the wall of the mixing chamber and extends along the wall of the mixing chamber around the height direction. The plurality of spray elements are spaced apart on the spray pipe and are all connected to the spray pipe.
[0010] In an optional embodiment, the spray element of the first spray assembly is a first spray element, and the spray element of the second spray assembly is a second spray element. Both the first spray element and the second spray element are set at an angle to the height direction, and the spray nozzle of the first spray element is set towards the bottom of the mixing chamber, while the spray nozzle of the second spray element is set towards the top of the mixing chamber.
[0011] In an optional embodiment, the angle between the first spray element and the height direction is α1, satisfying: 15°≤α1≤60°.
[0012] In an optional embodiment, the angle between the second spray element and the height direction is α2, satisfying: 15°≤α2≤60°.
[0013] In an optional embodiment, the stirring assembly includes a stirring tank and a stirring element. The stirring tank is provided with the stirring chamber, and the stirring element is disposed in the stirring chamber. In the height direction, the stirring element is located between the bottom spray assembly furthest from the bottom of the stirring chamber and the spray assembly closest to the bottom of the stirring chamber. The stirring element rotates relative to the stirring tank about the height direction.
[0014] In an optional embodiment, the stirring assembly further includes a driving member connected to the stirring tank and driven by the stirring member, the driving member being used to drive the stirring member to rotate about the height direction.
[0015] Secondly, this application provides a mine backfilling device, including: a vertical mixing device as described in any of the foregoing embodiments.
[0016] The vertical stirring device of this application has the following advantages:
[0017] In the vertical mixing device of this application, the slurry is mixed within the mixing chamber. Since each spray assembly is located within the mixing chamber and connected to a high-pressure water supply line via a connecting pipe, high-pressure water can be sprayed into the mixing chamber through the spray assemblies. During the mixing process, if the slurry concentration needs to be adjusted, one or more flow control valves can be opened to allow any one or more spray assemblies to spray high-pressure water into the mixing chamber, thereby adjusting the slurry concentration. When cleaning of the mixing chamber is required, all flow control valves can be opened to allow all spray assemblies to spray high-pressure water into the mixing chamber, thus cleaning the interior of the mixing chamber. Furthermore, since multiple spray components are spaced apart along the height direction, they can clean all parts of the mixing chamber, thereby improving the cleaning effect inside the mixing chamber. At the same time, the high-pressure water sprayed by the spray components can generate a strong impact on the inside of the mixing chamber, thereby quickly flushing away the slurry inside the mixing chamber, thus improving the cleaning efficiency and effect inside the mixing chamber. It is also unnecessary to periodically remove the solidified slurry inside the mixing chamber. Thus, the vertical mixing device of this application can reduce the cleaning difficulty.

[0035] Reference Figure 1 as well as Figure 2 As shown, the vertical stirring device involved in the embodiments of this application has a height direction x. The vertical stirring device includes: a stirring component 100, a plurality of spraying components 200 and a supply component 300.
[0036] Specifically, the mixing assembly 100 is provided with a mixing chamber 110; each spray assembly 200 is disposed in the mixing chamber 110 and is arranged at intervals along the height direction x; the supply assembly 300 includes a high-pressure water supply pipeline 310, multiple connecting pipelines 320 and multiple flow regulating valves 330, one end of each connecting pipeline 320 is connected to the high-pressure water supply pipeline 310, the other end of each connecting pipeline 320 is connected to a spray assembly 200, and each connecting pipeline 320 is provided with a flow regulating valve 330.
[0037] It should be noted that the height direction x is Figure 1 The direction indicated by x in the middle.
[0038] In the vertical mixing device of this application, the slurry is mixed within the mixing chamber 110. Since each spray assembly 200 is disposed within the mixing chamber 110 and each spray assembly 200 is connected to a high-pressure water supply pipeline 310 via a connecting pipe 320, high-pressure water can be sprayed into the mixing chamber 110 through the spray assembly 200. During the mixing process, if it is necessary to adjust the slurry concentration, one or more flow control valves 330 can be opened according to the concentration adjustment requirements, allowing one or more spray assemblies 200 to spray high-pressure water into the mixing chamber 110, thereby achieving the adjustment of the slurry concentration. When it is necessary to clean the mixing chamber 110, all flow control valves 330 can be opened, allowing all spray assemblies 200 to spray high-pressure water into the mixing chamber 110, thereby achieving the cleaning of the interior of the mixing chamber 110. Furthermore, since multiple spray components 200 are arranged at intervals along the height direction x, it is possible to clean all parts of the mixing chamber 110 through multiple spray components 200, thereby improving the cleaning effect inside the mixing chamber 110. At the same time, the high-pressure water sprayed by the spray components 200 can generate a strong impact on the inside of the mixing chamber 110, thereby quickly flushing the slurry inside the mixing chamber 110, thus improving the cleaning efficiency and cleaning effect inside the mixing chamber 110. Therefore, there is no need to periodically remove the solidified slurry inside the mixing chamber 110. Thus, the vertical mixing device of this application can reduce its cleaning difficulty.
[0039] Reference Figure 2 As shown, the multiple spraying components 200 include a first spraying component 210 and a second spraying component 220. The first spraying component 210 is disposed near the top of the mixing chamber 110, and the second spraying component 220 is disposed near the bottom of the mixing chamber 110.
[0040] In this embodiment, during the slurry mixing process, if it is necessary to adjust the slurry concentration, the flow regulating valve 330 on the connecting pipe 320 connected to the first spray assembly 210 can be opened first, allowing the first spray assembly 210 to spray high-pressure water into the mixing chamber 110, thereby changing the slurry concentration. If the slurry concentration has not yet reached the expected concentration, the flow regulating valve 330 on the connecting pipe 320 connected to the second spray assembly 220 can be opened, allowing both the first and second spray assemblies 210 to spray high-pressure water into the mixing chamber 110 simultaneously, thereby improving the efficiency and effect of slurry concentration adjustment. Simultaneously, the flow rate of the high-pressure water sprayed by the first and second spray assemblies 210 can be changed by adjusting the opening degree of the flow regulating valve 330, thereby expanding the range of slurry concentration adjustment. When it is necessary to clean the inside of the mixing chamber 110, the flow regulating valves 330 on the two connecting pipes 320 are opened at the same time, so that the first spray assembly 210 and the second spray assembly 220 spray high-pressure water into the mixing chamber 110 at the same time. This allows the high-pressure water to be sprayed from the top and bottom of the mixing chamber 110 onto the chamber wall at the same time, thereby improving the cleaning effect and cleaning efficiency of the inside of the mixing chamber 110.
[0041] Continue to refer to Figure 2 As shown, the supply component 300 also includes a high-pressure air supply pipeline 340 and an air volume regulating valve 350. The high-pressure air supply pipeline 340 is connected to the connecting pipeline 320 that is connected to the second spray component 220, and the air volume regulating valve 350 is installed on the high-pressure air supply pipeline 340.
[0042] In this embodiment, since the high-pressure air supply pipeline 340 is connected to the connecting pipeline 320 connected to the second spray assembly 220, and the air volume regulating valve 350 is installed on the high-pressure air supply pipeline 340, the air volume regulating valve 350 can be opened during the mixing process of the slurry so that the high-pressure air enters the mixing chamber 110 through the second spray assembly 220, thereby strengthening the mixing effect of the slurry by the high-pressure air and improving the mixing effect of the slurry. At the same time, the air volume of the high-pressure air can be changed by adjusting the opening of the air volume regulating valve 350, thereby adjusting the strengthening effect of the high-pressure air on the mixing of the slurry.
[0043] Reference Figure 5 As shown, the spray assembly 200 includes a spray pipe 230 and a plurality of spray elements 240. The spray pipe 230 is connected to the cavity wall of the mixing chamber 110 and extends along the cavity wall of the mixing chamber 110 around the height direction x. The plurality of spray elements 240 are spaced apart on the spray pipe 230 and are all connected to the spray pipe 230.
[0044] In this embodiment, since the spray pipe 230 is connected to the cavity wall of the mixing chamber 110 and extends along the cavity wall of the mixing chamber 110 in the height direction x, and multiple spray elements 240 are spaced apart on the spray pipe 230, when high-pressure water enters the mixing chamber 110 through the multiple spray elements 240, the high-pressure water can be evenly distributed in the mixing chamber 110 in the height direction x, thereby improving the cleaning effect on the inside of the mixing chamber 110 and improving the uniformity of the slurry concentration adjustment.
[0045] Reference Figure 3 as well as Figure 4 As shown, the spray element 240 of the first spray assembly 210 is the first spray element 241, and the spray element 240 of the second spray assembly 220 is the second spray element 242. Both the first spray element 241 and the second spray element 242 are set at an angle to the height direction x, and the spray nozzle of the first spray element 241 is set towards the bottom of the mixing chamber 110, while the spray nozzle of the second spray element 242 is set towards the top of the mixing chamber 110.
[0046] In this embodiment, since the spray nozzle of the first spray member 241 is arranged facing the bottom of the mixing chamber 110, the high-pressure water sprayed from the first spray member 241 can be sprayed from the top of the mixing chamber 110 to the bottom of the mixing chamber 110, so that all parts inside the mixing chamber 110 can be sprayed with high-pressure water, thereby improving the cleaning effect inside the mixing chamber 110. Since the spray nozzle of the second spray member 242 is arranged facing the top of the mixing chamber 110, the high-pressure water sprayed from the second spray member 242 can be sprayed from the bottom of the mixing chamber 110 to the top of the mixing chamber 110, thereby increasing the coverage of the high-pressure water inside the mixing chamber 110, and further improving the cleaning effect inside the mixing chamber 110.
[0047] Reference Figure 3 As shown, the angle between the first spray element 241 and the height direction x is α1, which satisfies: 15°≤α1≤60°.
[0048] Specifically, in this embodiment, α1 can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc.
[0049] In this embodiment, if α1 < 15°, the angle between the first spray element 241 and the height direction x will be too small. As a result, the high-pressure water sprayed by the first spray element 241 will concentrate at the edge of the mixing chamber 110, preventing the high-pressure water from reaching the middle of the mixing chamber 110. This further reduces the cleaning effect inside the mixing chamber 110. If α1 > 60°, the angle between the first spray element 241 and the height direction x will be too large. As a result, the high-pressure water sprayed by the first spray element 241 will concentrate at the middle of the mixing chamber 110, preventing the high-pressure water from reaching the chamber wall of the mixing chamber 110. This also reduces the cleaning effect inside the mixing chamber 110. When 15° ≤ α1 ≤ 60°, the sprayed water can be evenly distributed inside the mixing chamber 110, thereby improving the cleaning effect of the mixing chamber 110 and improving the uniformity of slurry concentration adjustment.
[0050] Reference Figure 4 As shown, the angle between the second spray element 242 and the height direction x is α2, which satisfies: 15°≤α2≤60°.
[0051] Specifically, in this embodiment, α2 can be 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc.
[0052] In this embodiment, if α2 < 15°, the angle between the second spray element 242 and the height direction x will be too small. As a result, the high-pressure water sprayed by the second spray element 242 will concentrate at the edge of the mixing chamber 110, preventing the high-pressure water from reaching the middle of the mixing chamber 110. This further reduces the cleaning effect inside the mixing chamber 110. If α2 > 60°, the angle between the second spray element 242 and the height direction x will be too large. As a result, the high-pressure water sprayed by the second spray element 242 will concentrate at the middle of the mixing chamber 110, preventing the high-pressure water from reaching the chamber wall of the mixing chamber 110. This also reduces the cleaning effect inside the mixing chamber 110. When 15° ≤ α2 ≤ 60°, the sprayed water can be evenly distributed inside the mixing chamber 110, thereby improving the cleaning effect of the mixing chamber 110 and improving the uniformity of slurry concentration adjustment.
[0053] Specifically, the values of α1 and α2 can be the same or different, and the specific values are determined according to the volume of the stirring chamber 110 and the structural position inside the stirring chamber 110.
[0054] Reference Figure 6As shown, the stirring assembly 100 includes a stirring tank 120 and a stirring element 130. The stirring tank 120 is provided with a stirring chamber 110. The stirring element 130 is disposed in the stirring chamber 110. In the height direction x, the stirring element 130 is located between the bottom spray assembly 200 furthest from the stirring chamber 110 and the spray assembly 200 closest to the bottom of the stirring chamber 110. The stirring element 130 rotates relative to the stirring tank 120 about the height direction x.
[0055] In this embodiment, since the agitator 130 is disposed in the mixing chamber 110 and rotates relative to the mixing tank 120 about the height direction x, the slurry in the mixing chamber 110 can be stirred by the rotation of the agitator 130. In the height direction x, since the agitator 130 is located between the bottom spray assembly 200 furthest from the mixing chamber 110 and the spray assembly 200 closest to the bottom of the mixing chamber 110, it can be ensured that the high-pressure water sprayed by the multiple spray assemblies 200 covers all positions of the agitator 130, thereby improving the cleaning effect of the agitator 130.
[0056] Specifically, in this embodiment, the agitator 130 is located in the middle of the mixing tank 120, and a plurality of first spray elements 241 and a plurality of second spray elements 242 are arranged around the agitator 130 to clean the agitator 130. At the same time, the spray elements 241 and the second spray elements 242 can avoid interference with the rotation of the agitator 130, thereby reducing the influence of the spray elements 240 on the slurry mixing process. Furthermore, when 15°≤α1≤60° and / or 15°≤α2≤60°, it can be ensured that the high-pressure water sprayed by the first spray elements 241 and the second spray elements 242 covers all positions of the agitator 130.
[0057] Continue to refer to Figure 6 As shown, the stirring assembly 100 also includes a driving member 140, which is connected to the stirring tank 120 and driven to the stirring member 130. The driving member 140 is used to drive the stirring member 130 to rotate about the height direction x.
[0058] In this embodiment, the stirring member 130 can be driven to rotate around the height direction x by the driving member 140, thereby realizing the stirring of the slurry in the mixing tank 120 by the stirring member 130.
[0059] The mine backfilling equipment involved in the embodiments of this application includes: the above-mentioned vertical mixing device.
[0060] In the mine backfilling equipment of this application, the aforementioned vertical mixing device can reduce the difficulty of cleaning, thereby improving the working efficiency of the mine backfilling equipment and extending its service life.
[0061] Specifically, in this embodiment, the mine filling equipment also includes a control device, which is electrically connected to the drive unit 140, flow regulating valve 330 and air volume regulating valve 350 of the above-mentioned vertical mixing device, and is used to control the start and stop of the drive unit 140, and at the same time control the opening and closing and the opening degree of the flow regulating valve 330, and control the opening and closing and the opening degree of the air volume regulating valve 350.
