Description

Technical Field

[0001] The present application relates to the technical field of mine drainage, and in particular to a drainage device and a drainage system. Background Art

[0002] In recent years, with the increasing demand for mineral resources, the economic value and economic and social benefits of the development and utilization of ore deposits have been significantly enhanced. The mine drainage system is an important part of the underground mine production, and shoulders the important task of discharging mine water to the ground. If the underground water inflow cannot be discharged in time, it will pose a great threat to production and the lives of underground workers.

[0003] In the underground mine drainage system, multi-stage centrifugal pumps are widely used due to their high head, good reliability and low price. Its working principle is that the impeller rotating at high speed, due to the action of centrifugal force, throws the liquid from the center of the impeller to the outer edge of the impeller and flows out along the discharge port at a relatively high pressure. At this time, a certain vacuum is formed at the center of the impeller due to the liquid being thrown out, and there is a pressure difference between the atmospheric pressure on the liquid surface on the side of the water inlet pipe and the center of the pump body. Therefore, the liquid in the sump enters the pump under the action of the pressure difference. The impeller rotates continuously, and the liquid is continuously sucked in and discharged.

[0004] However, in high-altitude areas, due to the decrease of the natural atmospheric pressure, the suction height of the centrifugal pump is limited. Or factors such as the long service life of the centrifugal pump equipment, high salinity of groundwater, and turbid water quality will all affect the suction height of the equipment, resulting in a smaller effective volume of the underground sump, more accumulated water to be drained and unable to be dredged, bringing many threats and troubles to safety and production.

[0048] In the related art, in a general underground mine drainage system, a centrifugal pump and a water inlet pipe are cooperated, and a pressure difference is formed between the atmospheric pressure on the liquid level on one side of the water inlet pipe and the center of the pump body to suck out the liquid in the sump. However, in high-altitude areas, due to the decrease of the natural atmospheric pressure, the suction height of the centrifugal pump is limited. Or factors such as the long service life of the centrifugal pump equipment, high salinity of groundwater, and turbid water quality will all affect the suction height of the equipment, resulting in a smaller effective volume of the underground sump, more stored water to be drained and unable to be dredged, bringing many threats and troubles to both safety and production.

[0066] Wherein, the first control valve 1241 is disposed between the pressurizing unit 122 and the draining unit 123, and the first control valve 1241 is configured to control the liquid in the pressurizing unit 122 to flow into or stop flowing into the draining unit 123.

[0067] Specifically, for example, the pressurizing unit 122 and the draining unit 123 are connected through a pipeline, then the first control valve 1241 is disposed on the pipeline between the pressurizing unit 122 and the draining unit 123, and further controls the groundwater in the pressurizing unit 122 to flow into or stop flowing into the draining unit 123 by opening or closing the first control valve 1241.

[0068] In addition, the second control valve 1242 is disposed between the water absorption member 113 and the draining unit 123, and the second control valve 1242 is configured to control the draining unit 123 to suck or stop sucking the liquid in the water absorption member 113.

[0069] Specifically, for example, the water absorption member 113 and the draining unit 123 are connected through a pipeline, then the second control valve 1242 is disposed on the pipeline between the water absorption member 113 and the draining unit 123, and further controls the draining unit 123 to suck or stop sucking the groundwater in the water absorption member 113 by opening or closing the second control valve 1242.

[0070] Optionally, as Figure 3 and Figure 4As shown, the drainage part 123 includes a centrifugal pump 1231 and a driving part 1232.

[0071] Among them, the centrifugal pump 1231 is arranged in the second accommodation cavity 1211, and the centrifugal pump 1231 is located on one side of the pressurizing part 122.

[0072] Specifically, the centrifugal pump 1231 is communicated with the water absorption part 113, and the centrifugal pump 1231 is communicated with the pressurizing part 122.

[0073] Among them, the first control valve 1241 is arranged between the centrifugal pump 1231 and the pressurizing part 122, the second control valve 1242 is arranged between the centrifugal pump 1231 and the water absorption part 113, the centrifugal pump 1231 is used to receive and discharge the liquid output by the pressurizing part 122, and suck out the liquid in the water absorption part 113.

[0074] In addition, the driving part 1232 is arranged in the second accommodation cavity 1211, the driving part 1232 is located on the side adjacent to the centrifugal pump 1231 and the pressurizing part 122, and the driving part 1232 is in transmission connection with the centrifugal pump 1231, and the driving part 1232 is used to drive the centrifugal pump 1231 to operate.

[0078] Specifically, by closing the second control valve 1242 and opening the first control valve 1241, the submersible pump 1121 pumps the groundwater in the first accommodation chamber 1111 to the buffer water tank 1221. Among them, when the submersible pump 1121 inputs groundwater into the buffer water tank 1221, it is buffered by the buffer water tank 1221, and the pressure in the buffer water tank 1221 is enhanced. Then, the groundwater in the buffer water tank 1221 feeds water to the centrifugal pump 1231 in a forced-in manner through the first control valve 1241, that is, the groundwater is forced into the centrifugal pump 1231. Further, through the action of the centrifugal pump 1231, the groundwater is discharged to the ground, thus realizing mine drainage.

[0079] In this embodiment, the forced-in water supply to the centrifugal pump 1231 is realized through the submersible pump 1121, the buffer water tank 1221 and the first control valve 1241, avoiding the suction lift limit and improving the safety and reliability of mine drainage.

[0080] In addition, by closing the first control valve 1241 and opening the second control valve 1242, the centrifugal pump 1231 can directly suck the groundwater in the first accommodation chamber 1111 through the second pipeline. That is, in this embodiment, by opening and closing the first control valve 1241 and the second control valve 1242, the centrifugal pump 1231 can be switched between forced-in water supply and suction water supply, thus realizing the reliability of the water supply end of the centrifugal pump 1231.

[0081] It should be noted that the drainage device 100 of this embodiment realizes the forced-in water supply to the centrifugal pump 1231 through the submersible pump 1121, the buffer water tank 1221 and the first control valve 1241, avoiding the influence of the centrifugal pump 1231 being restricted by the suction lift when the atmospheric pressure is low, and reducing the influence of the suction lift being limited due to the long service life of the centrifugal pump 1231.

[0082] In addition, in this embodiment, the centrifugal pump 1231 can perform suction water supply in extreme cases through the water absorption member 113 and the second control valve 1242. Such extreme cases are, for example, when the pumping part 112 or the pressurizing part 122 needs to be repaired.

[0083] Through the switching between the forced-in water supply and the suction water supply of the centrifugal pump 1231 in this embodiment, when the pumping part 112 and the pressurizing part 122 are being repaired, the water absorption member 113 and the centrifugal pump 1231 can be used for suction drainage.
