Description

Technical Field

[0001] This invention relates to the field of underground drainage technology, and in particular to an underground direct-drive drainage device for gold mines. Background Technology

[0002] Gold mines are generally located at great depths, and the surrounding rocks of the ore bodies often contain clay, soft rock, and broken gold-bearing veins. These rocks are extremely prone to softening and disintegration when exposed to water. As mining progresses, a large amount of underground water containing mud, sand, and fine gold particles is easily generated. To ensure the safety of deep gold mining and to prevent waterlogging and tunnel collapse, it is necessary to use specialized drainage and dewatering devices to promptly remove the muddy water and ensure the continuous and stable operation of gold mining.

[0003] Currently, most gold mines use mud pumps and surface-driven screw pumps in conjunction with delivery pipes to drain accumulated water. Although the pipe openings are equipped with filters, the accumulated water underground is mixed with silt, clay particles, and slag fragments, which easily adhere to and clog the filters and the inner walls of the pipes. This reduces the drainage flow rate and can easily cause pipe blockages, requiring frequent shutdowns for unblocking. This not only increases the workload but also severely restricts the efficiency of deep mining operations and is detrimental to the continuous and stable production of the mine.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Example 1, referring to Figure 1 - Figure 3 The first embodiment of the present invention provides a direct-drive drainage device for gold mines. The device includes: a base 1, a drainage unit 2 fixedly installed on the base 1, and a collection unit 3 fixedly installed on the drainage unit 2. The drainage unit 2 includes a drainage component 21 fixedly installed on the base 1 for driving drainage operations; Furthermore, the collection unit 3 includes a filter assembly 31 fixedly installed on the discharge component 21, a drive assembly 32 fixedly installed on the filter assembly 31, a crushing assembly 33 slidably installed on the drive assembly 32, and a collection assembly 34 fixedly installed on the filter assembly 31; the filter assembly 31 is used to intercept silt and impurities, the drive assembly 32 is used to connect to and drive the crushing assembly 33, the crushing assembly 33 is used to crush and scrape off silt and large impurities, and the collection assembly 34 is slidably connected to the crushing assembly 33 for collecting and discharging solid silt and impurities. During operation, in gold mine underground drainage operations, for highly turbid water environments containing clay, soft rock, gold-bearing fine particles, and slag debris, the drainage component 21 is controlled to initiate the collection process, allowing gold-bearing sludge and mine wastewater to be transported through the filter assembly 31. The filter assembly 31 can accurately intercept gold-bearing sludge, clay particles, and slag debris, ensuring smooth drainage while effectively retaining solid impurities. As the amount of gold-bearing sludge and slag impurities intercepted by the filter assembly 31 gradually increases, with the cooperation of the collection component 34, the sludge impurities are squeezed into the collection component 34 and discharged in a directed manner. At the same time, the collection component 34 can prevent the gold-bearing sludge from flowing back and contaminating the underground working face. When the filter assembly 31 is filled with gold-bearing sludge... When excessive amounts of gold slag or large pieces of slag cause blockage, the drive component 32 and the crushing component 33 are activated in conjunction, allowing the crushing component 33 to extend into the filter component 31 to crush and break down the gold-bearing sludge and large pieces of slag adhering to the inner wall. The crushed impurities and waste are then pushed to the collection component 34 for discharge, ensuring the continuous and efficient operation of the filter component 31 under the complex water conditions of gold mines. In addition, the pre-treatment of solid-liquid separation and impurity crushing can accurately separate gold-bearing solid materials, reducing the energy consumption of subsequent gold-bearing material ashing and ensuring that pollutants are discharged in compliance with standards. It also provides a reliable basis for the analysis of gold ore characteristics, optimization of smelting process parameters, and coordinated operation of environmental protection equipment, helping to achieve the goals of high efficiency, energy saving, and environmental protection in subsequent smelting and recycling of gold mines.

[0033] Example 2, refer to Figure 1 - Figure 4 This is the second embodiment of the present invention, which differs from the first embodiment in that: the filter assembly 31 includes a collection pipe 311 fixedly installed on the collection component 21, a connector 312 fixedly installed on the inner wall of the collection pipe 311, and a filter element 313 slidably installed on the connector 312; wherein, the collection pipe 311 is used for collection and transportation, the connector 312 is used for connection and fixation, the filter element 313 is used for filtering silt and impurities, and a collection port 315 is also fixedly installed on the collection pipe 311 for extracting silt and impurities; an elastic cable 314 is fixedly installed on the filter element 313, the other end of which passes through the connector 312 and is fixed to the collection pipe 311 for connecting and fixing the filter element 313.

[0034] Compared to Embodiment 1, this embodiment further optimizes the collection component 34: the collection component 34 includes a sewage discharge component 341 fixedly installed on the collection pipe 311, a rotating rod 344 rotatably installed on the inner wall of the sewage discharge component 341, a coil spring 343 fixedly installed on the rotating rod 344, and an interceptor 342 fixedly installed on the rotating rod 344; the interceptor 342 is rotatably connected to the sewage discharge component 341, and the rotating rod 344 drives the interceptor 342 to rotate and move by cooperating with the coil spring 343, while the sewage discharge component 341 is used to discharge sludge and sewage.

[0035] During use, when the drainage component 21 drains highly turbid water containing clay, soft rock fragments, gold-bearing fine particles, and slag from deep gold mines, the gold-bearing silt and slag impurities are transported upwards through the collection pipe 311 and then precisely separated into solid and liquid components by the filter component 313. All the gold-bearing silt, clay particles, and slag fragments are intercepted on the surface of the filter component 313. As impurities accumulate on the filter component 313, under the continuous impact of the high-pressure water flow in the gold mine, the elastic cable 314 pulls and shakes the filter component 313, causing the attached impurities to be squeezed into the side drainage component 341. This squeezing action pushes the interceptor component 342, which, in conjunction with the rotating rod 344 and the coil spring 343, flips over, removing the excess water. All gold-containing impurities on filter element 313 are squeezed into sewage discharge element 341 and discharged in a directed manner, continuously ensuring smooth drainage of gold mine water in collection pipe 311. This gold mine-specific filtration and collection structure specifically addresses the pain points of traditional drainage equipment, such as poor adaptability to complex muddy conditions in gold mines, susceptibility to blockage by gold-containing sludge and slag, frequent shutdowns for dredging, high labor intensity, and constraints on the efficiency of deep gold mining. It improves the efficiency of underground gold mine drainage, reduces operation and maintenance costs, and ensures continuous mining of deep gold mines. At the same time, the pre-processed high-efficiency solid-liquid separation treatment accurately intercepts gold-containing solid materials, which not only reduces the unit energy consumption of subsequent gold-containing material ashification and ensures stable and compliant emission of combustion pollutants, but also provides a high-quality raw material foundation for subsequent smelting and recovery processes in gold mines.

[0036] The remaining structure is the same as that in Example 1.

[0037] Example 3, referring to Figure 1 - Figure 12 This is the third embodiment of the present invention, which differs from the second embodiment in that: the driving assembly 32 includes a U-shaped tube 321 fixedly installed on the collection tube 311, a sealing element 322 fixedly installed on the inner wall of the U-shaped tube 321, a push rod 323 slidably installed on the inner wall of the sealing element 322, and a sliding pad 326 fixedly installed on the push rod 323; wherein, the U-shaped tube 321 is used to connect the sealing element 322 and the sealing element 327, the sealing element 322 is used to ensure the sealing of the inside of the U-shaped tube 321, the push rod 323 is used to connect the sliding pad 326, and the sliding pad 326 is used to cooperate with the squeezing and sliding inside the collection tube 311.

[0038] Compared to Embodiment 2, this embodiment is further optimized as follows: a return spring 325 is fixedly installed on the sliding pad 326, and its other end is fixedly connected to the seal 322 for sliding with the sliding pad 326; a sealing gasket 324 is fixedly installed on the other end of the push rod 323, and the sealing gasket 324 is slidably connected to the U-tube 321 for moving with the air pressure inside the U-tube 321.

[0039] Furthermore, a second sealing element 327 is fixedly installed on the inner wall of the U-tube 321 to maintain the internal seal of the U-tube 321; a second push rod 328 is slidably installed inside the second sealing element 327 to connect the second sealing gasket 329; the second sealing gasket 329 is fixedly installed on the second push rod 328, and the second sealing gasket 329 is slidably connected to the U-tube 321 to cooperate with the air pressure movement inside the U-tube 321.

[0040] Furthermore, the crushing assembly 33 includes a sealing part 332 fixedly mounted on the push rod 328, a motor 333 fixedly mounted on the inner wall of the sealing part 332, a connecting plate 334 fixedly mounted on the output end of the motor 333, an annular cutter 335 fixedly mounted on the connecting plate 334, and a rotary drill 336 fixedly mounted on the annular cutter 335; wherein, the sealing part 332 is used to connect the push rod 328 and slide inside the U-shaped tube 321, the motor 333 is used to drive the connecting plate 334 to rotate, the connecting plate 334 is used to support and fix the annular cutter 335 and the rotary drill 336, the annular cutter 335 is used to cut impurities, and the rotary drill 336 is used to crush impurities.

[0041] Furthermore, a scraper 338 is fixedly installed on the sealing part 332, and the scraper 338 is slidably connected to the filter element 313 for scraping off the adhering substances on the surface of the filter element 313; a drive sensor 331 is fixedly installed on the sealing part 327, and the drive sensor 331 is slidably connected to the sealing part 332 for cooperating with the drive motor 333 to rotate; a striking part 337 is fixedly installed on the connecting plate 334, and the striking part 337 is slidably connected to the filter element 313 for cooperating with the filter element 313 to perform striking vibration.

[0042] Furthermore, the scraping component 338 includes a main scraper 3381 fixedly installed on the sealing part 332, a second return spring 3382 fixedly installed on the inner wall of the main scraper 3381, and a secondary scraper 3383 fixedly installed on the other end of the second return spring 3382; wherein, the main scraper 3381 is used to scrape off the silt on the surface of the filter element 313, the second return spring 3382 is used to connect and slide to support the secondary scraper 3383, and the secondary scraper 3383 is slidably connected to the main scraper 3381, and can adapt to the curvature of the filter element 313 to scrape off the silt.

[0043] During use, if the collection tube 311 is blocked or large particles block the filter element 313, preventing normal discharge, water will gradually accumulate and compress inside the collection tube 311. At this time, the sliding pad 326 inside the U-shaped tube 321 is compressed first, compressing the return spring 325 and sliding inside the U-shaped tube 321. Simultaneously, the push rod 323 on the sliding pad 326 slides synchronously inside the U-shaped tube 321 with the cooperation of the seal 322. Since the air pressure inside the U-shaped tube 321 is kept balanced, the push rod 323 will push the air pressure to the other end of the U-shaped tube 321 when it moves, thereby squeezing the sealing pad 329. The sealing pad 329 will drive the push rod 328 to move with the cooperation of the seal 327, causing the sealing part 332 to slide out of the U-shaped tube 321 and into the collection tube 311.

[0044] At the same time, when the sealing part 332 disengages from the U-shaped tube 321, it also disconnects from the drive sensor 331, triggering the motor 333 inside the sealing part 332 to start rotating, driving the connecting plate 334 to rotate synchronously. During the rotation of the connecting plate 334, the annular cutter 335 and the rotary drill 336 on it cut and crush the minerals and large particles blocked on the filter element 313. At the same time, the striking element 337 on the connecting plate 334 rotates synchronously and continuously strikes the surface of the filter element 313, causing the filter element 313 to vibrate with the help of the elastic cord 314, further enhancing the surface cleaning effect.

[0045] In addition, the main scraper 3381 and the auxiliary scraper 3383 on the sealing part 332, under the action of the second return spring 3382, always stick to the surface of the filter element 313 to perform scraping operations, scraping off all the impurities that have been shaken off and crushed and pushing them into the discharge part 341. Under the synergistic action of the interceptor 342 and the coil spring 343, the clogging impurities are effectively removed and discharged in a timely manner.

[0046] After the filter element 313 is cleared of blockage, the collection tube 311 resumes conveying, the squeezing pressure disappears, and the sliding pad 326 returns to its original position with the help of the return spring 325. At the same time, the air pressure inside the U-shaped tube 321 returns to its original position, and the push rod 328 drives the sealing part 332 to slide back into the U-shaped tube 321. The sealing part 332 re-fits with the drive sensor 331, and the motor 333 stops driving. This prevents blockage inside the collection tube 311 and allows for automatic cleaning when blockage occurs without stopping the machine. This effectively improves the discharge efficiency, reduces operation and maintenance costs, and ensures continuous mining in deep gold mines. In addition, through high-efficiency solid-liquid separation and impurity crushing, it reduces the energy consumption of subsequent gold-bearing material ash formation, ensures that pollutants are discharged in compliance with standards, and provides a basis for material characteristic analysis, process parameter optimization, and equipment collaborative operation, helping to carry out subsequent smelting and recovery processes efficiently, energy-savingly, and environmentally friendly.

[0047] The remaining structure is the same as that in Example 2.
