Description

Technical Field

[0001] This invention relates to the field of mining blasting construction equipment technology, specifically to a device for treating water accumulation at the bottom of blasting holes. Background Technology

[0002] During mine blasting operations, after drilling, a large amount of water, gravel, rock fragments, and other particulate impurities easily accumulate at the bottom of the hole. If this accumulation is not effectively cleaned, it directly affects the subsequent blasting and charging operations, reducing blasting accuracy and safety. Currently, existing blasting hole cleaning equipment has a simple design, mostly only capable of simple water suction and cleaning. This limitation means it can only remove water from the hole bottom and cannot simultaneously and effectively clean the accumulated gravel, rock fragments, and other solid particulate impurities. With traditional cleaning methods, the long-term accumulation of gravel and impurities at the bottom of the hole easily causes blockage and irregular hole diameters, severely affecting the explosive loading effect, leading to uneven release of blasting energy and substandard blasting results. Currently, there is a lack of integrated cleaning equipment that can simultaneously handle water and gravel impurities. Conventional cleaning devices cannot effectively agitate, collect, and hold gravel of different sizes, resulting in incomplete gravel removal and large residues, failing to meet the requirements of high-standard blasting hole pretreatment. Therefore, there is an urgent need to design a treatment device that can simultaneously clean up water and gravel particles at the bottom of blast holes. Summary of the Invention

This effectively agitates and collects gravel and particulate impurities deposited at the bottom of the blast hole, preventing gravel accumulation and residue. Simultaneously, a multi-directional high-pressure jet auxiliary structure effectively agitates bottom-deposited impurities, assists in the stable climbing of gravel, and prevents collected gravel from falling back down. This significantly improves the comprehensiveness and cleanliness of cleaning impurities at the bottom of the blast hole, effectively solving the problems of incomplete gravel removal and large residues associated with traditional cleaning methods.

[0024] 2. By adopting a shared air-water hollow channel with an adaptive channel switching structure, it is possible to accurately switch between high-pressure jet slag collection and negative-pressure water pumping conditions. This eliminates the need for two independent pipeline structures, simplifying the overall structure of the device and reducing equipment costs and installation and maintenance difficulties.

[0048] This embodiment provides a device for treating water accumulation at the bottom of blast holes. This device is mainly used to simultaneously clean accumulated water, gravel, and particulate impurities at the bottom of blast holes. The device includes a cylindrical tube 1, with a collecting ring 2 fixedly installed at the bottom of the cylindrical tube 1. The outer surface of the collecting ring 2 and the inner wall of the cylindrical tube 1 form a closed receiving cavity, which is used to uniformly collect gravel and particulate impurities lifted from the bottom of the hole. The collecting ring 2 is fixedly installed on the inner wall of the cylindrical tube 1 by a partition ring 21. The partition ring 21 is arranged circumferentially around the collecting ring 2, providing stable support and ensuring the stability of the cavity structure between the collecting ring 2 and the cylindrical tube 1.

[0049] Several first rubber rings 22 are spaced apart along the height of the collecting ring 2. One end of each first rubber ring 22 is fixedly connected to the outer wall of the collecting ring 2, while the other end of each first rubber ring 22 is naturally separated from the outer wall of the collecting ring 2. This allows the first rubber rings 22 to remain in a closed state without external force, and to deform and open when compressed by gravel. An annular inlet is provided at the top of the collecting ring 2, and a second rubber ring 23 is fixedly installed at the annular inlet. The second rubber ring 23 is used to protect the top inlet of the collecting ring 2, and at the same time, it works with the high-pressure airflow to prevent gravel from falling off and to assist in the feeding effect.

[0050] A fixing plate 13 is fixedly installed inside the cylindrical tube 1. The fixing plate 13 is horizontally fixed in the internal cavity of the cylindrical tube 1. A micro motor 31 is fixedly installed above the fixing plate 13. The output end of the micro motor 31 is arranged vertically downwards. A stirring rod 3 is fixedly installed at the output end of the micro motor 31. The stirring rod 3 is vertically arranged in the inner area of ​​the collecting ring 2. Several stirring blades 32 are fixedly installed on the outer surface of the stirring rod 3. When the micro motor 31 is working, it can drive the stirring rod 3 and the stirring blades 32 to rotate at high speed, stirring the water and gravel at the bottom of the hole, so that the gravel can obtain centrifugal climbing power.

[0051] The stirring rod 3 has a through hollow channel along the axial direction inside. The stirring rod 3 has multiple second ports 302, which are connected to the hollow channel. A first connecting ring 46 is rotatably installed on the outer surface of the stirring rod 3 and located outside the second ports 302. The first connecting ring 46 can rotate freely relative to the stirring rod 3.

[0052] This device is equipped with a suction assembly, which includes a suction pump 4, a connecting pipe 41, a metal hose 42, a first connecting pipe 43, a second connecting pipe 44, and a third connecting pipe 45. One end of the connecting pipe 41 is fixedly connected to the suction end of the suction pump 4, and the other end of the connecting pipe 41 is fixedly connected to the air outlet end of the air compressor 5. A first valve 411 and a second valve 412 are fixedly installed on the pipe body of the connecting pipe 41. The connection point between the connecting pipe 41 and the metal hose 42 is located on the pipe section between the first valve 411 and the second valve 412.

[0053] The top end of the metal flexible hose 42 is fixedly connected to the connecting pipe 41, and the bottom end of the metal flexible hose 42 is fixedly connected to the top end of the first connecting pipe 43. The bottom end of the first connecting pipe 43 is fixedly connected to the body of the second connecting pipe 44. A first one-way valve 441 and a second one-way valve 442 are fixedly installed at both ends of the second connecting pipe 44, respectively. The connection point between the first connecting pipe 43 and the second connecting pipe 44 is located in the pipe section between the first one-way valve 441 and the second one-way valve 442.

[0054] A fourth connecting pipe 51 is fixedly connected to the body of the second connecting pipe 44.

The connection point between the third connecting pipe 45 and the second connecting pipe 44 is located on the pipe section outside the first one-way valve 441. The bottom end of the third connecting pipe 45 is fixedly connected to the first connecting ring 46.

[0055] Multiple first openings 301 are provided on the stirring rod 3 above the fixed ring 303. The first openings 301 are connected to the hollow channel. A second connecting ring 52 is rotatably installed on the outer surface of the stirring rod 3 corresponding to the outer side of the first openings 301. The second connecting ring 52 can rotate relative to the stirring rod 3. The second connecting ring 52 is fixedly connected to the end of the fourth connecting pipe 51.

[0056] A retaining ring 303 is installed inside the hollow channel of the stirring rod 3. The retaining ring 303 is fixedly installed on the inner wall of the stirring rod 3 and located above the second opening 302. A sealing plug 72 is slidably installed on the inner side of the retaining ring 303. The outer diameter of the sealing plug 72 is adapted to the inner diameter of the retaining ring 303, and the sealing plug 72 can slide up and down along the inner side of the retaining ring 303 to seal. A limiting ring 721 is fixedly installed at the bottom end of the sealing plug 72. The diameter of the limiting ring 721 is larger than the diameter of the sealing plug 72, which is used to limit the downward stroke of the sealing plug 72 and prevent the sealing plug 72 from falling off. A tension spring 73 is fixedly installed between the top end of the sealing plug 72 and the inner top surface of the stirring rod 3. Under normal conditions, the tension spring 73 pulls the sealing plug 72 upward to block the inner channel of the retaining ring 303.

[0057] Multiple sealing rings 7 are also provided inside the hollow channel of the stirring rod 3. The sealing rings 7 are respectively located at the through hole connecting the first nozzle 53 and the stirring rod 3 and at the through hole connecting the third nozzle 62 and the stirring rod 3. The sealing rings 7 are tightly fitted to the inner wall of the stirring rod 3 to achieve a seal. Adjacent sealing rings 7 are fixedly connected by a connecting rod 71. One of the sealing rings 7 is fixedly connected to the lower surface of the limiting ring 721 by the connecting rod 71, so that all sealing rings 7 can move up and down synchronously.

[0058] Multiple first nozzles 53 are fixedly installed on the outer surface of the stirring rod 3. All first nozzles 53 are inclined upward and connected to the hollow channel of the stirring rod 3. An annular tube 6 is provided on the outer side of the stirring rod 3 and above the top of the collecting ring 2. The annular tube 6 is fixedly connected to the hollow channel of the stirring rod 3 through multiple third nozzles 62. Multiple connecting tubes 61 are fixedly installed at equal intervals along the circumference of the annular tube 6. The connecting tubes 61 are all inclined downward and the bottom outlet of the connecting tube 61 is directly opposite the upper surface of the second rubber ring 23.

[0059] A fixing groove 54 is fixedly installed at the bottom end of the stirring rod 3. A filter screen 56 is fixedly installed inside the fixing groove 54. The filter screen 56 is used to filter impurities from the water entering the hollow channel. Multiple second nozzles 55 are fixedly installed at equal intervals along the circumference of the fixing groove 54. The second nozzles 55 are all inclined downwards and connected to the hollow channel. A sealing cover 541 is detachably installed at the bottom end of the fixing groove 54. The sealing cover 541 can be bolted to the bottom end of the fixing groove 54. The sealing cover 541 can be opened to clean the internal filtered impurities.

[0060] Multiple support feet 103 are fixedly installed at the bottom end of the cylindrical tube 1, which enables the device to be stably placed at the bottom of the blast hole. Multiple notches 101 are evenly spaced in the circumferential direction at the bottom end of the cylindrical tube 1. The notches 101 are connected to the receiving cavity between the collecting ring 2 and the cylindrical tube 1. A threaded part 102 is provided on the outer side of the bottom end of the cylindrical tube 1. A threaded sleeve 11 is detachably threaded on the threaded part 102. When the threaded sleeve 11 is installed, it seals the notches 101. After the threaded sleeve 11 is removed, the gravel and impurities collected inside the receiving cavity can be discharged and cleaned through the notches 101.

[0061] An annular cavity tube 8 is fixedly installed at the bottom end of the cylindrical tube 1. Multiple nozzles 81 are fixedly installed at equal intervals along the circumference of the annular cavity tube 8. The outlets of the nozzles 81 are angled upwards, and the angle of the nozzles 81 matches the angle of the inner surface of the collecting ring 2. A fifth connecting tube 82 is fixedly connected to the body of the fourth connecting tube 51. The bottom end of the fifth connecting tube 82 is connected to the interior of the annular cavity tube 8, allowing some of the high-pressure gas output from the air compressor 5 to enter the annular cavity tube 8 via the fifth connecting tube 82 and exit from the nozzles 81. An annular cover 801 is detachably installed at the bottom end of the annular cavity tube 8. The annular cover 801 can be bolted to the bottom end of the annular cavity tube 8, facilitating regular cleaning of any blockages inside the annular cavity tube 8 and ensuring unobstructed airflow.

[0062] A spring tube 14 is fixedly installed on the outer side of the top of the cylindrical tube 1 and on the outer side of the metal hose 42. The spring tube 14 protects, cushions, and prevents bending and breakage of the metal hose 42. An arc plate 12 is fixedly installed inside the cylindrical tube 1 and above the top of the collecting ring 2. The arc plate 12 is located above the path of the crushed stone and can block and guide the crushed stone that overflows during the climb, so that the crushed stone falls accurately into the receiving cavity at the top of the collecting ring 2, thereby improving the efficiency of impurity collection.

[0063] During the collection of crushed stone impurities, the cylindrical tube 1 is placed at the bottom of the blast hole, and the micro motor 31 is started. The micro motor 31 drives the stirring rod 3 and the stirring blade 32 to rotate at high speed, stirring the water and crushed stone at the bottom of the hole. Under the centrifugal force of the stirring, the crushed stone adheres tightly to the inner surface of the collecting ring 2 and rises upward. During the ascent, crushed stone of different sizes (large, medium, and small) squeezes the first rubber ring 22 at different heights, causing the first rubber ring 22 to deform under pressure and open, forming a feeding gap. Crushed stone of different sizes enters the receiving cavity through the gap at the corresponding height for graded collection. Extremely small crushed stone particles can directly enter the receiving cavity through the inlet at the top of the collecting ring 2.

[0064] Simultaneously, the air compressor 5 and the second valve 412 are turned on, the first valve 411 is closed, and the shut-off valve 511 on the fourth connecting pipe 51 is opened. High-pressure gas enters the first port 301 on the upper part of the stirring rod 3 through the connecting pipe 41, the metal hose 42, the first connecting pipe 43, the second connecting pipe 44, and the fourth connecting pipe 51. The high-pressure gas acts on the upper end of the sealing plug 72, pushing the sealing plug 72 to slide downward against the elastic force of the tension spring 73, opening the inner channel of the fixing ring 303, and at the same time driving each group of sealing rings 7 to move down synchronously, so that the first nozzle 53 and the third nozzle 62 are all connected.

[0065] A portion of the high-pressure gas is ejected obliquely upward through the first nozzle 53, adhering to the inner wall of the collecting ring 2 and blowing the crushed stone upward, increasing the extrusion pressure of the crushed stone on the first rubber ring 22, ensuring the stable opening of the feed opening, and providing some thrust for the crushed stone to rise; a portion of the high-pressure gas enters the annular pipe 6 through the third nozzle 62, and is sprayed onto the surface of the second rubber ring 23 by the downward-sloping connecting pipe 61, assisting the crushed stone to enter the receiving cavity and preventing the crushed stone in the cavity from flowing back and falling off; a portion of the high-pressure gas is sprayed downward through the bottom second nozzle 55, churning the crushed stone deposited at the bottom of the hole and improving the crushed stone agitation and collection effect; another portion of the high-pressure gas enters the annular cavity pipe 8 through the fifth connecting pipe 82, and is ejected by the upward-sloping nozzle 81, which adheres to the inner wall of the collecting ring 2, and the ejected high-pressure gas can better assist the crushed stone to rise.

[0066] After the crushed stone is collected, turn off the air compressor 5, close the second valve 412, close the shut-off valve 511, and open the first valve 411 and the suction pump 4. After the air compressor 5 stops supplying air, the sealing plug 72 returns to its original position under the tension of the tension spring 73, blocking the inner channel of the fixing ring 303. At the same time, the sealing ring 7 returns to its original position, blocking all nozzle channels and preventing water from flowing back into the nozzle air path.

[0067] The suction pump 4 creates negative pressure, and the water accumulated at the bottom of the hole enters the fixed groove 54 through the second spray pipe 55. After being filtered by the filter screen 56, it enters the hollow channel of the stirring rod 3, and then passes through the second port 302, the first connecting ring 46, the third connecting pipe 45, the second connecting pipe 44, the first connecting pipe 43, the metal hose 42, and the connecting pipe 41, and is finally extracted out of the hole by the suction pump 4, thus achieving a thorough cleaning of the water accumulated at the bottom of the blast hole.

[0068] After the operation is completed, the threaded sleeve 11 at the bottom of the detachable cylindrical tube 1 is used to clean the accumulated gravel and impurities inside the cavity through the notch 101. The detachable annular cover 801 cleans the impurities inside the annular cavity tube 8, and the detachable closed cover 541 cleans the filter screen 56 to trap impurities, ensuring that the device can operate stably and continuously for a long time.
