Description

Technical Field

[0001] This utility model relates to the field of mining drilling rig technology, and in particular to a rapid cooling device for mining drilling rigs. Background Technology

[0002] During operation, the hydraulic oil inside a mining drilling rig gradually heats up. When the temperature gets too high, the drilling rig needs to stop working. Therefore, a cooling device is needed to cool down the hydraulic oil, thereby improving work efficiency.

[0003] Existing cooling devices generally use fans for internal heat dissipation, which requires ventilation both inside and outside the cooling device. However, when the drilling rig is working, a lot of dust and particulate matter fly around, which can easily enter the cooling device and thus affect the heat dissipation effect.

[0004] Therefore, this utility model provides a rapid cooling device for mining drilling rigs to solve the problems existing in the prior art. Utility Model Content

An oil outlet pipe is fixedly connected and connected to one side of the oil tank, and a return oil pipe is fixedly connected and connected to the other side of the oil tank. The oil outlet pipe and the return oil pipe form a closed loop. A cooling box is installed on the return oil pipe, and a cooling pipe is installed inside the cooling box. The cooling pipe is sleeved on the return oil pipe, and a refrigeration component is connected to the cooling component. A cooling fan is installed on one side of the refrigeration component, and the cooling fan is fixedly installed on the inner wall of the cooling box. The cooling fan is connected to an air inlet pipe, and a filter box is installed on the air inlet pipe.

[0012] Preferably, the inner diameter of the air intake pipe increases sequentially from bottom to top.

[0013] This utility model discloses the following technical effects: During use, the oil tank supplies oil to the drilling rig.

[0019] During operation, mining drilling rigs often need to be shut down for cooling due to the rising temperature of the internal hydraulic oil, which seriously affects work efficiency.

[0020] Main Components of a Mining Drilling Rig Rapid Cooling System: A mining drilling rig rapid cooling system typically consists of key components such as a housing, heat-conducting blocks, hydraulic oil pipes, a cooling mechanism, and a dust removal mechanism. Housing: As the main structure of the cooling system, the housing houses various cooling components and provides necessary sealing and protection. Heat-conducting Blocks: The heat-conducting blocks are fixedly installed on the side walls of the housing and connected to the hydraulic oil pipes. Their main function is to conduct heat from the hydraulic oil to the cooling mechanism. Hydraulic Oil Pipes: The hydraulic oil pipes are part of the drilling rig's hydraulic system and are responsible for transporting hydraulic oil to the heat-conducting blocks. Cooling Mechanism: The cooling mechanism is the core component of the rapid cooling system and typically includes components such as spiral heat dissipation pipes, finned radiators, and a pump body. The cooling mechanism absorbs and removes heat from the heat-conducting blocks by circulating coolant. Dust Removal Mechanism: The dust removal mechanism removes accumulated dust from the surface of the cooling mechanism to prevent dust from affecting cooling efficiency. Common dust removal mechanisms include components such as a moving base, dust brushes, a motor, and a lead screw.

[0021] Working Principle of the Rapid Cooling Device for Mining Drilling Rigs: The rapid cooling device for mining drilling rigs primarily operates based on heat conduction and forced convection cooling. The detailed workflow is as follows: Heat Conduction: When the mining drilling rig is operating, hydraulic oil circulates in the system, generating heat. This heat is transferred to the heat-conducting blocks through hydraulic oil pipes. Coolant Circulation: After the pump starts, the coolant circulates between the spiral heat dissipation pipe, the outlet pipe, the finned radiator, and the inlet pipe. The coolant absorbs heat from the heat-conducting blocks in the spiral heat dissipation pipe and then flows into the finned radiator for heat dissipation. Forced Convection Cooling: The finned radiator increases its heat dissipation efficiency by increasing the heat dissipation area. Simultaneously, a fan drives airflow, further enhancing the radiator's cooling effect. Dust Removal: The motor drives the lead screw to rotate, and the moving seat moves via guide blocks and guide rods, thereby moving the dust removal brush across the surface of the finned radiator to remove accumulated dust.

[0022] Advantages and disadvantages of rapid cooling devices for mining drilling rigs: Rapid cooling devices for mining drilling rigs have significant advantages in improving cooling efficiency and extending the service life of the rig, but they also have some drawbacks. Advantages: High-efficiency cooling: By incorporating components such as spiral cooling pipes, finned radiators, and fans, the rapid cooling device can efficiently remove heat from the hydraulic oil, thereby reducing oil temperature and improving the drilling rig's working efficiency. Dust removal function: The dust removal mechanism can remove dust from the surface of the cooling mechanism, preventing dust accumulation that could reduce heat dissipation efficiency. Compact structure: Rapid cooling devices typically adopt a modular design, resulting in a compact structure that is easy to install and maintain. Disadvantages: Higher cost: Due to the complex cooling and dust removal mechanisms, the cost of rapid cooling devices is relatively high. Complex maintenance: The cooling and dust removal mechanisms contain multiple components, requiring regular maintenance and upkeep, increasing the complexity of maintenance. Certain environmental requirements: The performance of rapid cooling devices is affected by environmental conditions, such as air temperature, humidity, and dust concentration.

[0023] Future Development Directions of Rapid Cooling Devices for Mining Drilling Rigs: With technological advancements and improvements in the performance of mining drilling rigs, rapid cooling devices also require continuous development and improvement. The following are the future development directions for rapid cooling devices for mining drilling rigs:

[0024] Improved Cooling Efficiency: By optimizing the structure and materials of the cooling mechanism, the circulation efficiency of the coolant and the heat dissipation performance of the radiator are improved, further enhancing cooling efficiency. Intelligent Control: The introduction of an intelligent control system enables automatic adjustment and monitoring of the cooling device, improving equipment reliability and stability. Energy Saving and Environmental Protection: The use of environmentally friendly materials and energy-saving technologies reduces energy consumption and emissions during the cooling process, meeting the requirements of green mining development. Modular Design: The promotion of modular design concepts enables rapid assembly and disassembly of the cooling device, facilitating maintenance and upgrades. Multifunctional Integration: The cooling device is integrated with other functional components, such as vibrating screens and circulating tanks, to form a comprehensive solids control system, improving overall work efficiency.

[0025] Analysis of Key Technologies in Existing Structures: The rapid cooling device for mining drilling rigs effectively improves heat dissipation efficiency primarily due to its adoption of a series of advanced technologies and design concepts. The following is an in-depth discussion of these key technologies: High-Efficiency Heat Conducting Materials: As a crucial component for heat conduction, the material selection for the heat-conducting block is paramount. In existing devices, the heat-conducting block typically uses metal alloys with high thermal conductivity, such as aluminum or copper alloys, to ensure rapid and uniform heat transfer to the cooling mechanism. Furthermore, the connection between the heat-conducting block and the hydraulic oil pipes is carefully designed to reduce thermal resistance and improve heat transfer efficiency. Spiral Heat Dissipation Tube Design: The spiral heat dissipation tube not only increases the heat dissipation area but also improves the flow efficiency of the coolant through its unique structure. When the coolant flows within the spiral heat dissipation tube, it can make more thorough contact with the heat-conducting block, thereby more effectively absorbing heat. Simultaneously, the design of the spiral heat dissipation tube also considers fluid dynamics principles to ensure that the coolant forms turbulence when flowing within the tube, further improving heat exchange efficiency. Synergistic Effect of Finned Radiators and Fans: Finned radiators improve heat dissipation efficiency by increasing the heat dissipation area. The fin design typically considers aerodynamic principles to ensure smooth airflow through the radiator, carrying away heat. As a key component of forced convection cooling, the fan's speed and direction are adjustable to adapt to different working environments and heat dissipation requirements. The introduction of the fan significantly improves the radiator's heat dissipation efficiency, ensuring the cooling system can quickly respond to oil temperature changes. The introduction of motors and lead screws enables automated movement of the dust removal brushes, greatly improving dust removal efficiency. Simultaneously, the dust removal mechanism is designed for ease of maintenance and replacement, ensuring long-term high-efficiency operation. Intelligent Control System: With the continuous development of intelligent technology, existing mining drilling rigs' rapid cooling devices are also incorporating intelligent control systems. These systems typically include monitoring elements such as temperature sensors, flow sensors, and pressure sensors, as well as control elements such as controllers and actuators. The intelligent control system can monitor key parameters such as oil temperature and coolant flow rate in real time and automatically adjust the cooling system's operating status according to preset algorithms. This not only improves cooling efficiency but also reduces energy consumption and maintenance costs.

[0026] While rapid cooling devices for mining drills have achieved significant heat dissipation effects in existing structures, several challenges remain. The following discusses these challenges and directions for improvement: Balancing Material Performance and Cost: While high thermal conductivity metal alloys can improve heat transfer efficiency, their cost is also relatively high. Therefore, reducing costs while ensuring heat dissipation effectiveness is a major challenge for existing structures. Future improvements could involve exploring new composite materials or optimizing the processing technology of existing materials to reduce material costs and improve heat dissipation performance. The Conflict Between Heat Dissipation Area and Space Constraints: Space is typically very limited in mining drills. Therefore, increasing the heat dissipation area within a limited space is key to improving heat dissipation efficiency. Future improvements could involve adopting more compact heat dissipation structure designs, such as micro-finned heat sinks and integrated cooling modules, to achieve higher heat dissipation efficiency within limited space. Stability and Reliability of Intelligent Control Systems: While intelligent control systems can improve the automation level and heat dissipation efficiency of cooling devices, their stability and reliability must also be considered. Future improvements could involve strengthening the hardware and software design of the control system to improve its anti-interference and fault tolerance capabilities, ensuring stable operation of the cooling device in harsh working environments. Environmental protection and energy conservation requirements: With the increasing awareness of environmental protection and the introduction of energy conservation policies, the rapid cooling devices of mining drilling rigs also need to meet higher environmental protection and energy conservation requirements.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figures 1-3 As shown, this embodiment provides a rapid cooling device for a mining drilling rig, including an oil tank 1. An oil outlet pipe 2 is fixedly connected and connected to one side of the oil tank 1, and a return oil pipe 3 is fixedly connected and connected to the other side of the oil tank 1. The oil outlet pipe 2 and the return oil pipe 3 form a closed loop. A cooling box 5 is installed on the return oil pipe 3. A cooling pipe 6 is installed inside the cooling box 5. The cooling pipe 6 is sleeved on the return oil pipe 3. The cooling pipe 6 is connected to a refrigeration component. A cooling fan 12 is installed on one side of the refrigeration component. The cooling fan 12 is fixedly installed on the inner wall of the cooling box 5. The cooling fan 12 is connected to an air inlet pipe 16. A filter box 15 is installed on the air inlet pipe 16. An exhaust pipe 4 is fixedly connected and connected to the side of the cooling box 5 away from the air inlet pipe 16.

[0030] During operation, oil tank 1 supplies oil to the drilling rig. As the oil temperature rises, it flows back into oil tank 1 through return oil pipe 3. A cooling box 5 installed on return oil pipe 3 cools the hydraulic oil, maintaining a constant temperature within oil tank 1. A cooling pipe 6, fitted over return oil pipe 3, further cools the hydraulic oil. The coolant in cooling pipe 6 carries away heat, and the refrigeration components further cool the heat-absorbing coolant, facilitating recycling. A cooling fan 12 exhausts hot air from inside the cooling box 5 through exhaust pipe 4, reducing the internal temperature. The cooling fan 12 is connected to an intake pipe 16, on which a filter box 15 is installed. The filter box 15 filters impurities, ensuring the cleanliness of the cooling box 5, reducing damage to internal parts, and maintaining good heat dissipation. This invention features a simple structure, ease of use, significantly improved drilling rig heat dissipation efficiency, effectively prevents equipment damage caused by overheating, and extends service life. Furthermore, its compact structure facilitates installation and maintenance, prevents impurities from entering the cooling box 5, and adapts to various complex mining environments.

[0031] The design is further optimized. The refrigeration component includes an inlet pipe 7 connected to a cooling pipe 6. An outlet pipe 11 is connected to the side of the cooling pipe 6 furthest from the inlet pipe 7. The inlet pipe 7 and the outlet pipe 11 form a closed loop. A heat sink 10 and a cooler 9 are sequentially installed on the outlet pipe 11 for cooling the internal liquid. The heat sink 10 and the cooler 9 dissipate the heat absorbed by the coolant, thereby reducing the coolant temperature and facilitating its circulation. When the internal temperature of the cooling tank 5 is too high, the cooling fan 12 starts to expel the hot air.

[0032] The design was further optimized by installing a water pump 8 on the inlet pipe 7 to provide power for the liquid flow.

[0033] In a further optimized design, the cooling fan 12 is connected to a connector 13, which is fixedly embedded in the outer wall of the cooling box 5. The end of the connector 13 furthest from the cooling fan 12 is detachably connected to an installation pipe 14, which is connected to a filter box 15. The cooling fan 12 is connected to the air intake pipe 16 via the connector 13 and the installation pipe 14, allowing external air to enter the cooling box 5 and expel the hot air inside, thus preventing excessive internal temperature from damaging components.

[0034] The design has been further optimized by installing a filter assembly inside the filter box 15, which is used to filter dust or particulate matter.

[0035] The design is further optimized, with the filter assembly comprising a filter screen 17, a filter cloth 18, and a filter cotton 19 installed sequentially from bottom to top within the filter box 15. The filter box 15 is detachably connected to the mounting pipe 14 and the air inlet pipe 16, facilitating replacement and cleaning. The multi-layered arrangement of the filter screen 17, filter cloth 18, and filter cotton 19 significantly improves the filtration effect and prevents dust accumulation within the cooling box 5 from affecting heat dissipation.

[0036] The design was further optimized by arranging the intake pipe 16 in an S-shape. This S-shape allows some dust to settle on the pipe wall, thereby reducing the pressure on the filter components and improving the filtration effect.

[0037] The design was further optimized by increasing the inner diameter of the intake pipe 16 from bottom to top. The intake end of the intake pipe 16 has a small diameter, thus blocking the entry of large particles and achieving a preliminary filtration effect.
