Description

Technical Field

[0001] This invention relates to the field of rock drilling, and in particular to a mobile water-storage type pressurized water and gas supply station for rock drilling and its usage method. Background Technology

[0002] In large-scale underground engineering construction projects, rock drilling is a crucial step. Its stability and continuity significantly impact construction progress and project quality, and its reliance on drilling water and compressed air is indispensable. However, traditional rock drilling operations typically rely on external pipelines for water and air supply. This method is often costly due to long distances (hundreds or even thousands of meters), pipeline damage and leakage, pipeline construction costs, and labor expenses, resulting in high construction costs and environmental concerns. Therefore, developing a mobile, water-storage-based pressurized water and air supply station for rock drilling is of paramount importance. Summary of the Invention

[0003] The purpose of this invention is to provide a mobile water-storage type pressurized water and gas supply station for rock drilling and its usage method, which can provide continuous and stable water and gas supply for rock drilling machines, significantly improving construction efficiency and quality, and saving a large amount of construction water.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for using a mobile water-storage type rock drilling pressurized water and gas supply station, comprising the following steps: Step S1: Connect the output end of the multi-stage booster pump and the output end of the high-pressure airflow distributor to the handheld rock drill. Step S2: Start the vortex blower. The wastewater carrying slag discharged from the borehole is drawn into the primary sedimentation tank through the ray-type wastewater recovery pipe coil under the negative pressure generated by the vortex blower. When the water level reaches the preset water level of the water level gauge, the vortex blower stops working, and the drill slag naturally settles to the bottom of the tank. The water above the overflow port passes through the gravity-type one-way valve secondary filtration tank. The filtered clean water flows into the tertiary filtration tank for further sedimentation of fine particles. When the water level reaches the overflow port, it flows into the quaternary filtration tank. When the water level reaches the set position, the water level signal is transmitted to the controller. When rock drilling begins, the water pump starts the multi-stage booster pump according to the start command to supply water to the rock drill. Step S3: External air undergoes initial filtration through a fully automatic self-cleaning air filter, removing most of the dust particles suspended in the air generated by the explosion and other construction activities. It then passes through a first and second stage air filter to remove even finer dust particles. After passing through a safety filter, it enters the first-stage compressor for initial compression, then through an internal flow channel to the second-stage air compressor for further compression. It then enters an air-cooled cooler for cooling, and finally enters a vortex high-pressure oil-gas separator to separate the high-pressure air and oil in the oil-gas mixture. The condensate produced during separation is also automatically separated by an automatic oil-water separator installed at the bottom of the vortex high-pressure oil-gas separator. An automatic anti-backflow device constantly protects the normal operation of the front-end device based on sudden pressure changes. Compressed air enters the high-pressure airflow distributor and stainless steel ball valve to supply the rock drilling equipment.

[0018] Please see Figures 1 to 10 The present invention provides an embodiment: a method for using a mobile water-storage type pressurized water and gas supply station for rock drilling, comprising the following steps: Step S1: Connect the output end of the multi-stage booster pump 10 and the output end of the high-pressure airflow distributor 48 to the handheld rock drill. Step S2: Start the vortex blower. The wastewater carrying slag discharged from the borehole is drawn into the primary sedimentation tank 6 under the negative pressure generated by the vortex blower through the ray-type wastewater recovery pipe coil. When the water level reaches the preset water level of the water level gauge, the vortex blower stops working, and the drill slag naturally settles to the bottom of the tank. The water above the overflow port flows into the secondary filtration tank 7 through the gravity one-way valve. The filtered clean water flows into the tertiary clean water tank 9 to further settle fine particles. When the water level reaches the overflow port, it flows into the quaternary clean water tank 12. When the water level reaches the set position, the water level signal is transmitted to the controller. When rock drilling starts, the water pump starts the multi-stage booster pump according to the start command to supply water to the rock drill. Step S3: External air undergoes initial filtration via a fully automatic self-cleaning air filter 44, removing most of the dust particles suspended in the air generated by the explosion and other construction activities. It then passes through primary and secondary air filters 54 to further remove finer dust particles. After passing through a safety filter, it enters the primary compressor unit for initial compression, then flows through an internal channel to the secondary air compressor unit 57 for further compression. It then enters an air-cooled cooler for cooling, and finally enters a vortex high-pressure oil-gas separator 46 to separate the high-pressure air and oil in the oil-gas mixture. The condensate produced during separation is also automatically separated by an automatic oil-water separator installed at the bottom of the vortex high-pressure oil-gas separator 46. An automatic anti-backflow device 47 protects the front-end device from sudden pressure changes to ensure normal operation. Compressed air enters the high-pressure airflow distributor 48 and stainless steel ball valve 49 to supply the rock drilling equipment.

[0019] Please see Figures 1 to 10 The present invention provides an embodiment: a mobile water storage type rock drilling pressure water and air supply station, including a wastewater recovery and filtration supply system, a compressed air supply system 24 and a walking system, wherein the wastewater recovery and filtration supply system and the compressed air supply system 24 are installed on the walking system; The wastewater recycling, filtration, and resupply system includes multiple ray-type suction coils 14, a power unit, a multi-stage sedimentation and filtration water purification device, and a multi-stage booster pump 10.

A quick-connect water supply connector 22 is used for connection; a wastewater recovery and supply system is included, comprising multiple ray-type wastewater recovery coils that recover wastewater generated during rock drilling under negative pressure to a primary sedimentation tank 6. After natural sedimentation, the wastewater overflows through a coarse filter to a secondary filtration tank 7. The secondary filtration tank 7 is equipped with an automatic filtration and slag removal mechanism. The filtered water undergoes further sedimentation and overflows to a tertiary purification tank 9. After further sedimentation in the tertiary purification tank 9, the water overflows to a quaternary purification tank 12, supplying power to a multi-stage booster pump. This invention is applicable to construction environments with scarce water resources, especially suitable for the harsh working conditions of underground rock drilling in water-scarce areas of Northwest China. The wastewater recovery and filtration system is powered by the first control box 20. Its unique ray-shaped wastewater recovery coil efficiently recovers small amounts of water from uneven surfaces and gravel crevices on complex construction sites. Gravity-type one-way valves connect the various water tanks. When the vortex negative pressure fan starts, it ensures that the primary sedimentation tank 6 is under negative pressure, allowing external wastewater to be smoothly recovered to the primary sedimentation tank 6 via the ray-shaped wastewater coil. A water level sensor is installed in the primary sedimentation tank 6; when the water level reaches the set position, the vortex negative pressure fan stops operating. A filter 41 is also installed in the primary sedimentation tank to guide the water flowing into it, preventing any impact on the sedimentation effect. At this point, the water flows through the coarse filter and gravity one-way valve into the secondary filtration tank 7. The secondary filtration tank 7 is equipped with an automatic filtration and sludge removal mechanism. When water from the primary sedimentation tank 6 enters the secondary filtration tank 7, the automatic filtration and sludge removal mechanism starts operating to further remove fine solid impurities such as stone powder from the water flow. The automatic filtration and sludge removal mechanism includes filter paper 68, a drive motor 67, and rollers 42. The filter paper 68 is mounted on one side of the secondary filtration tank 7 via rollers, and the drive motor 67 is located on the other side of the secondary filtration tank 7. The output end of the drive motor 67 is connected to the rollers 42. One end of the filter paper 68 passes through the inlet of the secondary filtration tank 7 and connects to the rollers 42. The rollers 42 tension the filter membrane. Through the action of the drive motor 67, the filter membrane is replaced periodically to prevent filter membrane failure. Even finer impurities, after further sedimentation, flow through a gravity-type one-way valve into the tertiary water purification tank 9, and after further sedimentation, flow into the quaternary water purification tank 12 for use by the multi-stage booster pump. The multi-stage booster pump draws water from the fourth-stage clean water tank 12, pressurizes it, and supplies it to the rock drill for reuse.The primary sedimentation tank 6 and the secondary filtration tank 7 are designed with inspection ports, which require regular cleaning of the accumulated waste inside.

[0029] Please continue reading. Figures 7 to 10As shown, in one embodiment of the present invention, the vortex high-pressure oil-gas separator 46 is connected to a temperature control valve 62. The first output end of the temperature control valve 62 is connected to an oil cooler 63. The output end of the oil cooler 63 is connected to an oil filter 64. The output end of the oil filter 64 is connected to a secondary air compressor 57. The second output end of the temperature control valve 62 is connected to the oil filter 64 via a bypass 72. The vortex high-pressure oil-gas separator 46 is connected to a return oil check valve 65. The output end of the return oil check valve 65 is connected to the input end of the primary air compressor 56. External air enters the primary air compressor 56 and the secondary air compressor 57 via a fully automatic self-cleaning air filter 44 and a multi-stage air filtration device. The compressed air and lubricating oil enter the vortex high-pressure oil-gas separator 46 through pipelines for oil-gas and partial water vapor separation. The separated oil returns to the air compressor through pipelines and filters. As is well known, air releases heat when compressed, so the oil-gas-liquid mixture heats up during compression. However, the characteristics of an air compressor dictate that water separation is most effective when the oil-gas-liquid mixture is between 75-85℃, ensuring the oil's moisture content is sufficient for proper lubrication and pressure sealing of the compressor. The function of the temperature control valve 62 is as follows: when the temperature is below 75℃, the valve is closed, allowing oil from the vortex high-pressure oil-gas separator 46 to flow back to the compressor via a bypass (without passing through the oil cooler 63). Therefore, the temperature control valve 62 helps the oil heat up to its optimal operating temperature as quickly as possible. When the temperature exceeds 75℃, the valve gradually opens as the temperature rises, allowing oil from the vortex high-pressure oil-gas separator 46 to flow back to the compressor via the oil cooler 63 (while the bypass is gradually closed by the temperature control valve 62). Therefore, the temperature control valve 62 prevents the oil from overheating and maintains its optimal operating temperature. When the temperature exceeds 85℃, the temperature control valve 62 is fully open. Oil from the vortex high-pressure oil-gas separator 46 flows back to the compressor unit via the oil cooler 63 (the bypass is closed at this time). Due to the excessively high temperature, the cooling fan is activated to dissipate excess heat from the radiator into the ambient air. Therefore, the radiator reduces the oil temperature and maintains the optimal operating temperature. The return oil check valve 65 returns excess oil that has slowly seeped into the oil-gas separator filter element (oil separator core) back to the compressor unit, allowing it to re-enter the main unit's lubrication system for reuse, while also reducing the residual oil content entering the compressed air. The minimum pressure valve 50 maintains a certain pressure difference between the inside and outside of the oil separator core (inside is higher than outside) to allow compressed air to flow. When the external pressure is higher than the internal pressure, the minimum pressure valve 50 closes to prevent external compressed air from flowing back in. The safety valve 70 ensures that the pressure inside the vortex high-pressure oil-gas separator 46 operates safely within a set range. If the pressure exceeds the set value, it automatically releases pressure to ensure the safe operation of the system.

[0030] The present invention operates on the following principle: Through a combination of a wastewater recovery and supply system, a compressed air supply system 24, and a flexible walking system, the walking system flexibly moves within the confined space of the wastewater recovery and supply system and the compressed air supply system 24. The wastewater recovery and supply system allows external wastewater to be smoothly recovered to the primary sedimentation tank 6 via a ray-shaped wastewater pipe coil. The water flows through a coarse filter and a gravity-operated one-way valve into the secondary filtration tank 7. Finer impurities are further settled in the secondary filtration tank 7, then flow through a gravity-operated one-way valve into the tertiary clean water tank 9, and after further sedimentation, flow into the quaternary clean water tank 12 for use by a multi-stage booster pump. The multi-stage booster pump draws water from the quaternary clean water tank 12, pressurizes it, and supplies it to the rock drill for reuse. The compressed air supply system 24 filters the turbid air in the tunnel through a fully automatic self-cleaning air filter 44, then through a primary air filter 53, a secondary air filter 54, and a tertiary safety air filter before entering the primary air compressor 56 for initial compression. It then undergoes secondary compression through a secondary air compressor 57 to reach the operating pressure for downstream equipment. The compressed air then enters a high-pressure air cooler 45 for cooling, and finally enters a vortex-type high-pressure oil-gas separator 46 to separate the high-pressure air and oil in the oil-gas mixture. The compressed air then enters a high-pressure airflow distributor 48 and a stainless steel ball valve 49 to supply the downstream equipment. This system ensures continuous and stable water and air supply for rock drilling operations, significantly improving construction efficiency and quality, shortening the construction period, and featuring a simple structure and convenient operation.

[0031] The above description is only a preferred embodiment of the present invention and should not be construed as a limitation of this application. All equivalent changes and modifications made in accordance with the scope of the patent application of the present invention should be covered by the present invention.

Claims

1. A method for using a mobile water-storage type pressurized water and gas supply station for rock drilling, characterized in that, Includes the following steps: Step S1: Connect the output end of the multi-stage booster pump and the output end of the high-pressure airflow distributor to the handheld rock drill. Step S2: Start the vortex blower. The wastewater carrying slag discharged from the borehole is drawn into the primary sedimentation tank through the ray-type wastewater recovery pipe coil under the negative pressure generated by the vortex blower. When the water level reaches the preset water level of the water level gauge, the vortex blower stops working, and the drill slag naturally settles to the bottom of the tank. The water above the overflow port flows into the secondary filtration tank through the gravity one-way valve. The filtered clean water flows into the tertiary clean water tank for further sedimentation of fine particles. When the water level reaches the overflow port, it flows into the quaternary clean water tank. When the water level reaches the set position, the water level signal is transmitted to the controller. When rock drilling starts, the water pump starts the multi-stage booster pump according to the start command to supply water to the rock drill. Step S3: External air undergoes initial filtration through a fully automatic self-cleaning air filter, removing most of the dust particles suspended in the air generated by the explosion and other construction activities. It then passes through a first and second stage air filter to remove even finer dust particles. After passing through a safety filter, it enters the first-stage compressor for initial compression, then through an internal flow channel to the second-stage air compressor for further compression. It then enters an air-cooled cooler for cooling, and finally enters a vortex high-pressure oil-gas separator to separate the high-pressure air and oil in the oil-gas mixture. The condensate produced during separation is also automatically separated by an automatic oil-water separator installed at the bottom of the vortex high-pressure oil-gas separator. An automatic anti-backflow device constantly protects the normal operation of the front-end device based on sudden pressure changes. Compressed air enters the high-pressure airflow distributor and stainless steel ball valve to supply the rock drilling equipment.
