[0002] Metal and non-metal mines using filling mining method for mining activities need to convey tailings to two destinations, i.e. filling station and tailings pond, and the tailings conveying to the filling station needs to be prioritized. Since the filling operation is carried out with the underground mining situation, it has the characteristics of intermittent work, and the demand for tailings quantity also often changes, so the corresponding tailings conveying system needs to meet various working conditions conveying process.

[0003] In the related art, on the one hand, the tailings conveying system is divided into two parts, i.e. filling station conveying and tailings pond conveying, and each tailings pool is arranged to receive the tailings sent by the ore dressing plant.

On the other hand, when the filling station conveying and the tailings pond conveying use one tailings pool to receive the tailings sent by the ore dressing plant, the filling station conveying pump set and the tailings pond conveying pump set cannot be automatically switched, and all need to be manually operated and controlled, which also makes the conveying system poor in stability, has a high probability of error operation, and is prone to cause accidents such as pump flooding.

[0043] Embodiments of the present application are described in detail below with reference to the accompanying drawings. The embodiments described below by way of example with reference to the accompanying drawings are illustrative and are intended to explain the present application, and are not to be understood as limiting the present application.

[0044] A tailings conveying system of an embodiment of the present application is described below with reference to the accompanying drawings.

[0045] As shown in the drawings, the tailings conveying system of the embodiment of the present application comprises a first storage tank 1, a second storage tank 2, a filling station 7, a tailings pond 8 and a first detection member 21. Figure 1 The first storage tank 1 is used to receive tailings, and the first storage tank 1 is in communication with the second storage tank 2 through a pipeline, so that the tailings in the first storage tank 1 flow into the second storage tank 2. The filling station 7 is connected to the first storage tank 1, and the tailings pond 8 is connected to the second storage tank 2. The first detection member 21 is arranged on the second storage tank 2 and below the pipeline in the height direction (e.g. the up-down direction in the drawings) of the second storage tank 2, and the first detection member 21 is used to detect the height of the tailings in the second storage tank 2. When the height of the tailings detected by the first detection member 21 reaches a first preset height, the second storage tank 2 is in communication with the tailings pond 8, so that the tailings in the second storage tank 2 flow into the tailings pond 8. The ratio of the first preset height to the height of the second storage tank 2 is 1 / 5-1 / 3.

[0046] Figure 1 Specifically, as shown in the drawings, the first storage tank 1 and the second storage tank 2 are connected through an overflow pipe 11, i.e. one end of the overflow pipe 11 is in communication with the first storage tank 1, and the other end of the overflow pipe 11 is in communication with the second storage tank 2, so that when the tailings in the first storage tank 1 reach a certain height, they can flow into the second storage tank 2 through the overflow pipe 11. Preferably, one end of the overflow pipe 11 is located above the other end of the overflow pipe 11.

[0047] Specifically, as shown in the drawings, the first storage tank 1 and the second storage tank 2 are connected through an overflow pipe 11, i.e. one end of the overflow pipe 11 is in communication with the first storage tank 1, and the other end of the overflow pipe 11 is in communication with the second storage tank 2, so that when the tailings in the first storage tank 1 reach a certain height, they can flow into the second storage tank 2 through the overflow pipe 11. Preferably, one end of the overflow pipe 11 is located above the other end of the overflow pipe 11. Figure 1 It can be understood that the first detection member 21 can be a liquid level meter, and the first detection member 21 is arranged in the second storage tank 2 and below the overflow pipe 11. That is, when the first detection member 21 detects the height information of the tailings in the second storage tank 2, i.e. the height of the tailings in the second storage tank 2 reaches the first preset height, the tailings in the second storage tank 2 are then discharged into the tailings pond 8.

[0048] In other words, the ratio of the first preset height to the height of the second storage tank 2 is 1 / 5-1 / 3, which can ensure that there is a certain amount of tailings in the second storage tank 2, so that the second storage tank 2 can avoid being emptied when discharging tailings into the tailings pond 8.

[0049]

[0050] ​​In addition, when the tailings need to be delivered to the filling station 7, the first storage tank 1 is communicated with the filling station 7 after the tailings are delivered to the first storage tank 1, so that the tailings in the first storage tank 1 are discharged into the filling station 7.

[0051] That is, the tailings delivery system of the embodiment of the present application first delivers the tailings into the first storage tank 1, and when the filling station 7 does not need the whole amount of tailings, the tailings in the first storage tank 1 are delivered to the second storage tank 2 through the pipeline, and the tailings in the second storage tank 2 are delivered to the tailings pond 8 after the first detection member 21 detects that the height of the tailings in the second storage tank 2 reaches the preset height, so that the delivery conflict between the first storage tank 1 and the second storage tank 2 under complex delivery conditions is avoided.

[0052] Therefore, the tailings delivery system of the embodiment of the present application can reasonably allocate the front end of the delivery system, can realize the bidirectional and self-switching delivery of the tailings, and has the advantages of high delivery efficiency and high automation level.

[0053] In some embodiments, as shown in Figure 1 The tailings delivery system of the embodiment of the present application further comprises a second detection member, which is arranged on the first storage tank 1 and below the pipeline in the height direction of the first storage tank 1, and is used to detect the height of the tailings in the first storage tank 1. When the second detection member detects that the height of the tailings reaches a second preset height, the first storage tank 1 is communicated with the filling station 7, so that the tailings in the first storage tank 1 flow into the filling station 7. The ratio of the second preset height to the height of the first storage tank is 1 / 5-1 / 3.

[0054] It can be understood that the second detection member can be a liquid level meter, which is arranged in the first storage tank 1 and below the overflow pipe 11. When the second detection member detects the height information of the tailings in the first storage tank 1, i.e., the height of the tailings in the first storage tank 1 reaches the second preset height, the tailings in the first storage tank 1 are delivered to the filling station 7.

[0055] In other words, the ratio of the second preset height to the height of the first storage tank 1 is 1 / 5-1 / 3, which can ensure that there is a certain amount of tailings in the first storage tank 1, so that the first storage tank 1 can avoid being emptied when discharging the tailings into the filling station 7.

[0056] Therefore, according to the above delivery conditions, the tailings delivery system of the embodiment of the present application can adapt to various delivery conditions, realize the bidirectional delivery of the tailings, and achieve the continuous and self-switching purpose of tailings delivery through the electrical connection of the overflow pipe, the detection member and the pump group.

[0057] In some embodiments, the tailings delivery system of the present application further comprises a first agitator 13 connected to the first storage tank 1 for agitating the tailings in the first storage tank 1, and a second agitator 22 connected to the second storage tank 2 for agitating the tailings in the second storage tank 2.

[0058] Specifically, as shown in Figure 1 the first agitator 13 comprises a first agitating head located in the first storage tank 1 and adjacent to the bottom of the first storage tank 1, so that the tailings in the first storage tank 1 can be fully agitated after the first agitator 13 is started. The second agitator 22 comprises a second agitating head located in the second storage tank 2 and adjacent to the bottom of the second storage tank 2, so that the tailings in the second storage tank 2 can be fully agitated after the second agitator 22 is started.

[0059] In some embodiments, the tailings delivery system of the present application further comprises a first pump set 3 connected between the first storage tank 1 and the tailings reservoir 8 and electrically connected to the first detection member 21 for receiving the detection signal output by the first detection member 21, so that the first pump set 3 is started to make the tailings in the first storage tank 1 flow into the tailings reservoir 8 when the first pump set 3 receives the detection signal. The tailings delivery system further comprises a second pump set 4 connected between the second storage tank 2 and the filling station 7 and electrically connected to the second detection member for receiving the detection signal output by the second detection member, so that the second pump set 4 is started to make the tailings in the second storage tank 2 flow into the filling station 7 when the second pump set 4 receives the detection signal.

[0060] Specifically, as shown in Figure 1 the first pump set 3 is connected between the first storage tank 1 and the filling station 7 to pump out the tailings in the first storage tank 1 and discharge them into the filling station 7, and the second pump set 4 is connected between the second storage tank 2 and the tailings reservoir 8 to pump out the tailings in the second storage tank 2 and discharge them into the tailings reservoir 8.

[0061] It can be understood that when the filling station 7 needs all the tailings, the second detection member is used to detect the tailings in the first storage tank 1, and when the tailings in the first storage tank 1 reach the second preset value, the second detection member transmits a starting signal to the first pump set 3 to start the first pump set 3, so as to realize the discharge of all the tailings in the first storage tank 1 into the filling station 7.

[0062] If the filling station 7 needs part of the tailings, the tailings need to be discharged to the filling station 7 first, that is, when the tailings in the first storage tank 1 reach the second preset value, the second detection member transmits a start signal to the first pump group 3 to start the first pump group 3. At this time, the tailings level in the first storage tank 1 continues to rise until it flows into the second storage tank 2 through the overflow pipe 11, and the tailings in the second storage tank 2 are detected by the first detection member 21. When the height of the tailings in the second storage tank 2 reaches the first preset value, the first detection member 21 transmits a start signal to the second pump group 4 to start the second pump group 4, so that the tailings in the second storage tank 2 are discharged to the tailings pond 8. At this time, if the filling station 7 needs all the tailings, since the first storage tank 1 always maintains a certain amount of tailings, the first pump group 3 is directly started, and all the tailings are directly discharged to the filling station 7 to meet the changing tailings conveying conditions.

[0063] If the filling station 7 does not need tailings, the tailings are discharged to the first storage tank 1 until the tailings in the first storage tank 1 flow into the second storage tank 2 through the overflow pipe 11. After that, the tailings in the second storage tank 2 are detected by the first detection member 21. When the height of the tailings in the second storage tank 2 reaches the first preset value, the first detection member 21 transmits a start signal to the second pump group 4 to start the second pump group 4, so that the tailings in the second storage tank 2 are discharged to the tailings pond 8.

[0064] Optionally, the first pump group 3 includes at least two first pumps 31 to meet the change of the amount of tailings required by the filling station, and the second pump group 4 includes at least two second pumps 41 to meet the conveying of all the remaining tailings to the tailings pond 8 except for the tailings conveyed to the filling station 7.

[0065] Preferably, as shown in Figure 1 two first pumps 31 are used to adjust the conveying amount of tailings to adapt to different conveying conditions, and the other first pump 31 is used as a standby pump. Similarly, the second pump group 4 includes three second pumps 41, two of which are used to adjust the conveying amount of tailings, and the other second pump 41 is used as a standby pump.

[0066] In some embodiments, the tailings conveying system of the embodiment of the present application further includes a first connecting pipe 5 and a second connecting pipe 6. One end of the first connecting pipe 5 is connected to the inlet of the first pump group 3, the other end of the first connecting pipe 5 is connected to the first storage tank 1, and the first connecting pipe 5 is located below the second detection member in the height direction of the first storage tank 1. One end of the second connecting pipe 6 is connected to the inlet of the second pump group 4, the other end of the second connecting pipe 6 is connected to the second storage tank 2, and the second connecting pipe 6 is located below the first detection member 21 in the height direction of the second storage tank 2.

[0067] It can be understood that one end of the first connecting pipe 5 is connected with the inlet of the first pump 31, the other end of the first connecting pipe 5 is connected with the first storage tank 1 and is close to the bottom position of the first storage tank 1, and the other end of the first connecting pipe 5 is below the second detection member, that is, after the tailings are injected into the first storage tank 1, when the height of the tailings in the first storage tank 1 exceeds the other end of the first connecting pipe 5, the height of the tailings in the first storage tank 1 can be detected by the second detection member, that is, the second preset height is greater than the height from the other end of the first connecting pipe 5 to the bottom of the first storage tank 1, so as to avoid that the air in the first storage tank 1 is extracted after the first pump group 3 is started.

[0068] Similarly, one end of the second connecting pipe 6 is connected with the inlet of the second pump 41, the other end of the second connecting pipe 6 is connected with the second storage tank 2 and is close to the bottom position of the second storage tank 2, and the other end of the second connecting pipe 6 is below the first detection member 21, that is, after the tailings are injected into the second storage tank 2, when the height of the tailings in the second storage tank 2 exceeds the other end of the second connecting pipe 6, the height of the tailings in the second storage tank 2 can be detected by the first detection member 21, that is, the first preset height is greater than the height from the other end of the second connecting pipe 6 to the bottom of the second storage tank 2, so as to avoid that the air in the second storage tank 2 is extracted after the second pump group 4 is started.

[0069] The tailings conveying method of the embodiment of the present application will be described below according to the accompanying drawings.

[0070] As shown in Figure 2 and Figure 3 , the tailings conveying method of the embodiment of the present application comprises the following steps:

[0071] judging the tailings flow direction, which can be divided into the following three cases: all the tailings are conveyed to the filling station; part of the tailings is conveyed to the filling station, and the other part of the tailings is conveyed to the tailings pond; all the tailings are conveyed to the tailings pond; wherein, the required amount of ore of the filling station can be considered first when judging the tailings flow direction.

[0072] injecting the tailings into the first storage tank;

[0073] if the filling station needs all the tailings, the tailings flow direction is that all the tailings are conveyed to the filling station, and the tailings in the first storage tank are conveyed to the filling station;

[0074] if the filling station needs part of the tailings, the tailings flow direction is that part of the tailings is conveyed to the filling station, and the other part of the tailings is conveyed to the tailings pond, the tailings in the first storage tank are first conveyed to the filling station, at this time, the liquid level of the tailings in the first storage tank continues to rise to the position of the overflow pipe, and overflows into the second storage tank; the height of the tailings in the second storage tank is detected, and when the height of the tailings in the second storage tank reaches the first preset height, the tailings are conveyed to the tailings pond;

[0075] if the filling station does not need the tailings, the tailings flow direction is that all the tailings are conveyed to the tailings pond,

[0076] The tailings in the first storage tank are transported to the second storage tank; the height of the tailings in the second storage tank is detected, and when the height of the tailings in the second storage tank reaches a first preset height, the tailings are transported to the tailings pond.

[0077] It can be understood that if the tailings are all transported to the filling station, the tailings are injected into the first storage tank for 1-2 minutes, and then the tailings in the first storage tank are transported to the filling station, and the rate of transporting the tailings to the first storage tank is greater than or equal to the rate of transporting the tailings to the filling station.

[0078] If the tailings flow to the filling station, the tailings are injected into the first storage tank for 1-2 minutes, and then the tailings in the first storage tank are transported to the filling station until the filling station is transported, and the tailings continue to be transported into the first storage tank, the tailings in the first storage tank continue to increase and flow into the second storage tank through the pipeline between the first storage tank and the second storage tank, and then the tailings in the second storage tank are transported to the tailings pond after the height of the tailings in the second storage tank reaches the first preset height is detected by the first detection member.

[0079] If the tailings flow to the tailings pond, the tailings continue to be transported to the first storage tank, so that the tailings in the first storage tank continue to increase and flow into the second storage tank through the pipeline between the first storage tank and the second storage tank, and then the tailings in the second storage tank are transported to the tailings pond after the height of the tailings in the second storage tank reaches the first preset height is detected by the first detection member.

[0080] In some embodiments, detecting the height of the tailings in the second storage tank comprises: providing a first detection member on the second storage tank, and the first detection member is used to detect the height of the tailings in the second storage tank.

[0081] It can be understood that the first detection member can be a liquid level meter, and the first detection member is arranged in the second storage tank to detect the height of the tailings in the second storage tank.

[0082] In some embodiments, as shown in Figure 3 Before the tailings in the first storage tank are transported to the filling station, the height of the tailings in the first storage tank is detected by a second detection member; when the height of the tailings in the first storage tank reaches a preset height, the tailings in the first storage tank are transported to the filling station.

[0083] It can be understood that the second detection member can be a liquid level meter, and the second detection member is arranged in the first storage tank to detect the height of the tailings in the first storage tank. If the tailings are all transported to the filling station, the tailings are injected into the first storage tank until the height of the tailings in the first storage tank reaches a second preset value is detected by the second detection member, and then the tailings in the first storage tank are injected into the filling station.

[0084] In some embodiments, the transporting the tailings in the first storage tank to the filling station comprises: starting the first pump group to transport the tailings in the first storage tank to the filling station by the first pump group, wherein the first pump group is electrically connected with the second detecting member, and the first pump group is started when the second detecting member detects that the height of the tailings in the first storage tank reaches the second preset height; and the transporting the tailings to the tailings pond comprises: starting the second pump group to transport the tailings in the second storage tank to the tailings pond by the second pump group, wherein the second pump group is electrically connected with the first detecting member, and the second pump group is started when the first detecting member detects that the height of the tailings in the second storage tank reaches the first preset height.

[0085] It can be understood that the first pump group is connected between the filling station and the first storage tank by a pipeline, and when the second detecting member detects that the height of the tailings in the first storage tank reaches the second preset height, the starting information is transmitted to the first pump group to start the first pump group, so as to transport the tailings in the first storage tank to the filling station.

[0086] Similarly, the second pump group is connected between the tailings pond and the second storage tank by a pipeline, and when the first detecting member detects that the height of the tailings in the second storage tank reaches the first preset height, the starting information is transmitted to the second pump group to start the second pump group, so as to transport the tailings in the second storage tank to the tailings pond.
