Description

[0002] In the field of rock breaking, traditional breaking methods mainly include blasting and mechanical breaking. Although the blasting method is efficient, its application is strictly limited in certain specific environments, such as mountainous topography superimposed on local seismic belts, ecological sensitive areas, and microclimate conditions. At the same time, blasting operations have safety hazards and can cause damage to the surrounding environment and personnel. The mechanical breaking method relies on breaking tools and equipment to directly act on the rock, but for high-hardness rocks, the equipment is severely worn, the breaking efficiency is low, and equipment failures frequently occur. For some soft rocks, their high deformation characteristics have higher requirements for the peak impact force and duration of the breaking equipment, increasing the breaking difficulty and cost.

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Reference Figures 1-4 The present invention provides a rock crushing device based on microwave technology, comprising:

[0058] The main frame 1 has a handrail 2 fixed on the top, a positioning frame installed on the bottom of the main frame 1, and a moving component installed below the main frame 1;

[0059] The drilling mechanism includes a manual lifting frame, a drill rod 3, a transmission assembly, and an energy supply module 4. The manual lifting frame is slidably connected to the main frame 1, and the drill rod 3 is vertically connected to the manual lifting frame. The transmission assembly is installed on the manual lifting frame and cooperates with the drill rod 3. The energy supply module 4 is installed on the side of the main frame 1 and is connected to the transmission assembly;

[0060] A microwave emitting unit is provided. A central hole is provided at the bottom of the drill pipe 3 along the axial direction. The microwave emitting unit is installed in the central hole. A hydraulic push rod is provided between the microwave emitting unit and the top of the central hole. A cooling system and a gas fracturing system are installed on the microwave emitting unit.

[0061] The intelligent monitoring module is connected to the microwave transmitting unit and is used to monitor the temperature of the microwave transmitting unit.

[0062] The core working principle of this microwave-based rock crushing device is to utilize the principle of microwave selective heating. A microwave transmitter is drilled deep into the rock, heating specific minerals within the rock and generating thermal stress, which in turn causes cracks and ultimately fractures the rock. Specifically, the high-frequency microwaves emitted by the microwave transmitter are absorbed by minerals within the rock (such as quartz) and converted into heat energy, causing the local temperature of the rock to rise rapidly. Differences in thermal expansion coefficients between different minerals generate thermal stress, which in turn triggers cracks and expands, ultimately breaking the rock.

[0063] During operation, the drilling mechanism uses a diamond drill bit to drill a hole in the target rock mass to a predetermined depth. This step provides a channel for the subsequent insertion of the microwave transmitter. The microwave transmitter unit is inserted into the hole through the hollow tube of the borehole, and the radiator is deployed. The radiator is designed with a spiral emission structure to enhance the penetration depth of the microwaves into the rock. The microwave transmitter unit is activated, emitting high-frequency microwaves (e.g., 2.45 GHz) with a power controlled within the range of 3-5 kW. Minerals within the rock selectively absorb heat, causing local temperatures to rise rapidly (e.g., to 600°C) within a short period of time. As the rock's internal temperature rises, thermal stresses are generated due to differences in thermal expansion coefficients between different minerals, which in turn induce radial cracks. Simultaneously, the gas injection port in the cooling system is activated, injecting compressed air into the rock, accelerating crack propagation and further promoting rock fragmentation. A temperature sensor in the intelligent control module monitors the rock's internal temperature in real time and feeds the data back to the power regulation unit. When the temperature exceeds a preset threshold (e.g., 700°C), the microwave output power is automatically reduced to prevent overheating of the probe and ensure safe operation of the device.

[0067] The mobile assembly utilizes a tripod 5 and wheels 6 to achieve flexible movement. The tripod 5 provides stable support, while the wheels 6 enable easy movement across varying terrains. To move the device, the operator tilts the device and pushes or pulls it, utilizing the rolling motion of the wheels 6.

[0100] The control module is connected with the microwave probe 23;

[0101] The end of the mounting head 21 is provided with a drill bit.

[0102] Further optimization, the cooling system comprises:

[0103] A cooling water pipe is mounted on the outer wall of the mounting head 21.

[0104] A water tank is fixed on the side wall of the main frame 1, and a circulating pump is mounted on the water outlet of the water tank. The output end of the circulating pump is connected to the cooling water pipe through a water supply pipe.

[0105] Further optimization, the gas fracturing system comprises:

[0106] A high-pressure air jet head 24 is mounted on the telescopic frame 22.

[0107] A high-pressure pump is connected to the high-pressure air jet head 24 through a high-pressure pipe.

[0108] Further optimization, the intelligent monitoring module comprises:

[0109] A temperature sensor is installed at the front end of the mounting head 21, and the temperature sensor is connected to the control module.

[0110] First, the drilling mechanism is used to drill precise holes in the target rock mass, providing a channel for the microwave emitter to penetrate. Then, the microwave emission unit is inserted into the hole along the hollow pipe of the drill hole and the radiator is unfolded. The radiator is designed as a spiral emission structure, which significantly enhances the penetration depth of microwaves in the rock, making the microwaves more effective in acting on the inside of the rock.

[0111] After starting the microwave emission unit, high-frequency microwaves (such as 2.45GHz) are emitted, with power controlled within the range of 3-5kW. The minerals in the rock (such as quartz) have selective heat absorption characteristics for microwaves, so they can quickly convert microwave energy into heat energy, causing the local temperature of the rock to rise rapidly (such as reaching 600℃) in a short time. As the temperature rises, thermal stress is generated between different minerals due to the difference in thermal expansion coefficient, which in turn triggers radial cracks, laying the foundation for subsequent rock fragmentation.

[0112] The cooling process is a key link to ensure the stable operation of the microwave emission unit and prevent overheating damage. During the microwave emission process, the microwave probe 23 will generate a large amount of heat due to long-term work, which will seriously affect its service life and fragmentation effect if not cooled in time.

[0113] To effectively address this issue, the device is equipped with an advanced cooling system. The cooling system cools the microwave probe 23 in all directions through the integration of a water-cooled circulation pipeline and a gas injection port. The water-cooled circulation pipeline uses the circulating flow of cooling water to remove the heat from the surface of the microwave probe 23, while the gas injection port further accelerates the heat dissipation by injecting compressed air. The two work together to ensure that the microwave probe 23 operates stably within the appropriate temperature range.

[0114] In addition, the cooling system is also equipped with an intelligent control module that can monitor the temperature of the microwave probe 23 in real time and automatically adjust the operating state of the cooling system according to the temperature data. When the temperature exceeds the preset threshold, the intelligent control module will automatically increase the flow and pressure of the cooling water and the injection intensity of the compressed air to more effectively reduce the temperature of the microwave probe 23, thereby ensuring its long-term stable operation.

[0115] The high-pressure gas fracturing process is another important means for the device to achieve rapid and efficient rock breaking. After the initial cracks are generated in the rock by the microwave emission, the high-pressure gas fracturing process further accelerates the expansion of the cracks and the breaking of the rock by injecting high-pressure gas into the rock.

[0116] In specific operation, the high-pressure gas fracturing system injects high-pressure gas into the rock through the high-pressure gas injection head 24. The high-pressure gas generates a large pressure difference in the rock, causing the existing cracks to further expand and deepen. At the same time, the impact of the high-pressure gas can also generate additional breaking force on the rock, thereby accelerating the rock breaking process.

[0117] To achieve more precise gas fracturing effect, the device is also equipped with a high-pressure pump and a pressure regulating device. The high-pressure pump can provide a stable source of high-pressure gas, while the pressure regulating device can accurately adjust the pressure and flow of the high-pressure gas injected into the rock according to the hardness of the rock and the breaking requirements. This precise gas fracturing control not only improves the breaking efficiency, but also reduces unnecessary energy consumption and dust generation during the rock breaking process.
