[0002] The mining industry is an important raw material industry, metal ores are the main raw materials of the smelting industry, and non-metallic ores are important chemical raw materials and building materials. Most mining fields will be tested as high-grade in-road mining methods. The in-road is multiple, the stoping speed is fast, and the filling frequency is high. However, when the in-road is filled, there is too much water in the connecting channel, which needs to be drained.

[0003] The patent number CN217270314U discloses a drainage device for a gold mining field, which mainly comprises a storage pool, a motor is installed on the outer side wall of the storage pool, a stirring blade is installed on the output shaft of the motor, the stirring blade is located in the interior of the storage pool, a pipeline is fixedly connected to the top cover plate of the storage pool and the outer side wall at the bottom of the storage pool, and a conveying pump is installed on the end surface of the pipeline. It also comprises a filter assembly arranged inside the storage pool near the top to play a filtering role. The filter assembly comprises a first fixed plate, a second fixed plate, a fixed block, a first spring and a mesh plate. The first fixed plate and the second fixed plate are symmetrically installed at the top end in the interior of the storage pool, and are rotationally connected through a rotating shaft. An installation groove is formed in the interior of the storage pool and away from the rotating shaft. Two fixed blocks are fixedly arranged on the end surfaces of the first fixed plate and the second fixed plate. The fixed block of the first fixed plate is located in the installation groove. A clamping groove is formed in the inner side wall of the storage pool and below the installation groove. The fixed block of the second fixed plate is located in the clamping groove. The first spring is fixedly connected to the inner bottom surface of the installation groove. Two mesh plates are fixedly arranged on the inner side walls of the first fixed plate and the second fixed plate.

[0004] The gold mining with stope drainage device in working, through the setting filter assembly, pipeline cooperation conveying pump to sewage pumping to the inside of storage pool, first through the first fixed plate of inclination, cooperation with the mesh of the inner wall of sewage primary filtration, because the pipeline is set near the top of the first fixed plate, under the action of gravity, accelerate the flow of sewage and impurities, when flow to the second fixed plate, because the density of the mesh of the second fixed plate is less than the density of the mesh of the first fixed plate, filter again, improve the effect of filtering impurities, because the first fixed plate and the second fixed plate are in "<" shape structure, and rotationally connected, after filtering, manually pressing the first fixed plate makes its fixed block compression first spring in the installation groove, through the rebound of the action of the first spring, repeat the action, can the impurities in the "<" shape structure play the role of compression and drainage, improve the efficiency and quality of filtration, facilitate the centralized cleaning of impurities between the first fixed plate and the second fixed plate, convenient personnel

[0005] From the above description, it can be known that: when the device filters impurities in sewage, the filter plate is used for filtering, and heavy metal particles are more likely to be stuck on the surface of the filter hole due to their large mass, causing filter clogging phenomenon, which seriously affects the efficiency of filtering. SUMMARY

[0006] (1) technical problems solved

[0007] In view of the deficiencies of the prior art, the present application provides a gold mining with stope drainage device, which utilizes the centrifugal force of the components during rotation to make large or heavy particles such as heavy metals move outward during flow filtration, so that some particles can be away from the industrial filter screen, reducing the occurrence of particle accumulation phenomenon, and the particles located at the periphery can be pushed to one side under the action of the spiral structure, thereby preventing the water flow from being blocked by the accumulation of particles, and the rotating spiral structure can further accelerate the flow of internal sewage, thereby further improving the filtering efficiency, solving the above technical problems.

[0008] (2) technical scheme

[0009] To achieve the above objectives, the present invention provides the following technical solution: a drainage device for gold mining operations, comprising a horizontal cylinder with a supporting base at the bottom and a cylindrical hollow cavity located at the center of the horizontal cylinder and open at both ends; a spiral rotation drive structure, which is mechanically sealed between the two ends of the cylindrical hollow cavity of the horizontal cylinder, and generates spiral motion on the inner wall of the cylindrical hollow cavity during rotation; a centrifugal structure located in the central area of ​​the spiral rotation drive structure, which drives the surrounding liquid in a rotational direction during rotation; and a rotary filter structure located in the central area of ​​the centrifugal structure, which drives the centrifugal structure to rotate synchronously.

[0010] The above technical solution utilizes the centrifugal force of the rotating components to cause large or heavy particles, such as heavy metals, to move outwards during flow filtration. This allows some particles to move away from the industrial filter screen, reducing particle accumulation. Furthermore, the particles on the periphery are pushed to one side by the spiral structure, preventing water flow obstruction caused by particle accumulation. The rotating spiral structure also accelerates the flow of internal wastewater, further increasing filtration efficiency.

[0011] Preferably, the spiral rotation drive structure includes a first circumferential plate and a second circumferential plate. The circumferential surfaces of the first and second circumferential plates are rotatably mounted inside the opposing end faces of the cylindrical hollow cavity via a mechanical seal structure. A spiral strip is installed on the opposing end faces of the first and second circumferential plates, near their circumferential surfaces. A main drive shaft extending to the outer side of the end face of the cylindrical hollow cavity is provided on the other end face of the first circumferential plate. A main pulley is provided at the end of the main drive shaft. A sewage inlet is provided at the center of the main drive shaft and the first circumferential plate, which can inject external liquid into the area between the first and second circumferential plates. An external component mounting hole is provided at the center of the second circumferential plate. The edge of the spiral strip is attached to the corresponding inner wall surface of the cylindrical hollow cavity. The mechanical seal structure consists of a stationary ring, a rotating ring, an elastic element spring seat, a set screw, a rotating ring auxiliary sealing ring, and a stationary ring auxiliary sealing ring. An anti-rotation pin is fixed on the pressure plate to prevent the stationary ring from rotating.

[0012] The above technical solution connects the inlet of the sewage inlet to the outlet of the sewage tank, and links the main pulley with the rotating pulley via a belt. It is important to ensure that the rotation direction of the main pulley is such that the driving direction generated by the rotating spiral blades is towards the water flow. When the spiral blades rotate, they guide the surrounding particles towards the water flow, allowing them to accumulate on the end face of the second circumferential plate. After a period of operation, the plate can be removed, allowing the fixed particles inside to be collected and cleaned, thus preventing particle accumulation upstream and accelerating the filtration process.

[0013] Preferably, the centrifugal structure during rotation includes a hollow rotating column, the center of which is provided with a closed inner hollow cavity. One end face of the inner hollow cavity is provided with an internal component fixing hole. Multiple annular array rectangular wings are provided in the middle of the circumferential surface of the hollow rotating column. Each rectangular wing has a flat liquid inlet groove inside that connects its end to the inner hollow cavity. There is a certain gap between the rectangular wing and the inner side of the spiral strip. The hollow rotating column is located in the central region of the spiral strip.

[0014] Through the above technical solution: when the hollow rotating column rotates with the rotary filter structure, the rectangular fins, due to their structural shape, cause the liquid around them to rotate with them. Once the liquid is rotating, the heavy metals and particles in the liquid will experience a centrifugal effect and tend to move outwards. The edges of these heavy metals and particles will adhere tightly to the corresponding inner wall of the columnar hollow cavity, thereby preventing these impurities from entering the vicinity of the annular industrial filter screen and reducing the occurrence of accumulation and clogging.

[0015] Preferably, the rotary filter structure includes a first rotating plate and a second rotating plate. The first rotating plate and the second rotating plate are fixedly connected at their opposite ends by a central connecting shaft. The other end of the first rotating plate is provided with a secondary drive shaft extending to the outer side of the other end of the cylindrical hollow cavity. The end of the secondary drive shaft is provided with an integral secondary pulley. The center of the central connecting shaft, the secondary drive shaft, and the secondary pulley is provided with a liquid discharge hole. An annular industrial filter screen is embedded at the opposite ends of the first rotating plate and the second rotating plate. The interior of the annular industrial filter screen forms a liquid retention cavity. The shaft of the central connecting shaft is provided with a plurality of liquid flow holes for the liquid in the liquid retention cavity to flow into the liquid discharge hole. The end of the second rotating plate is fixedly installed on the solid end face of the inner hollow cavity. The middle shaft of the secondary drive shaft is fixedly installed inside the internal component fixing hole, and the two are sealed at the installation position.

[0016] Through the above technical solution: when the auxiliary pulley rotates, it can drive the hollow rotating column to rotate, thereby transmitting rotational force. Furthermore, when some tiny particles adhere to the surface of the annular industrial filter screen, due to its rotational state, these tiny particles can be thrown out, thereby further reducing the occurrence of clogging. At the same time, the liquid can be filtered through the annular industrial filter screen before being discharged.

[0017] Compared with the prior art, the present invention provides a drainage device for gold mine operations, which has the following beneficial effects:

[0018] This gold mine employs a field drainage system that utilizes the centrifugal force of rotating components to cause large or heavy particles, such as heavy metals, to move outwards during flow filtration. This allows some particles to move away from the industrial filter screen, reducing particle accumulation. Furthermore, particles on the periphery are pushed to one side by the spiral structure, preventing water flow obstruction caused by particle accumulation. The rotating spiral structure also accelerates the flow of internal wastewater, further increasing filtration efficiency. Attached Figure Description

When some tiny particles adhere to the surface of the annular industrial filter 63, due to its rotation, these tiny particles can be thrown out, thereby further reducing the occurrence of clogging. At the same time, the liquid can be filtered through the annular industrial filter 63 before being discharged.
