Description

Technical Field

[0001] This invention relates to the fields of geotechnical engineering and mining engineering, and in particular to an adaptive control system for microwave fracturing parameters in large-scale ore. Background Technology

[0002] Currently, drill-and-blast method remains the primary means of rock breaking in mining operations. The ore broken by this method is characterized by large size differences and irregular shapes. The ore produced in the initial crushing is relatively large and needs to be transported by conveyor belt to a secondary crushing point for mechanical crushing. Mechanical crushing of ore consumes a large amount of electrical energy and causes mechanical wear, and large, hard pieces of ore are prone to clogging the crusher.

[0003] Microwaves are electromagnetic waves that can heat rocks and ores, offering selective, efficient, and controllable heating. Differences in the heating and mechanical properties of different minerals within rocks and ores can lead to internal thermal stress. When this thermal stress exceeds the strength of the rock or ores, it can cause cracks or even spalling. Existing research has shown that microwave technology can effectively reduce the strength and crushing difficulty of ores.

[0004] Applying microwave technology to the pre-fracture of large ores to reduce energy consumption in subsequent mechanical crushing has promising prospects. However, the large size differences between ores mean that the distance between the microwave radiator and the ore changes continuously as the ores move along the conveyor belt. This distance significantly affects the microwave fracturing effect. In addition, the moving ore may collide with the microwave radiator. Therefore, it is necessary to develop a microwave fracturing device that can rapidly respond to changes in microwave radiation distance based on ore size and movement speed. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a large-scale microwave fracturing parameter adaptive control system for ores; it can achieve adaptive control of microwave power, distance between microwave radiator and ore, and ore transport speed according to ore size, thereby improving the microwave fracturing effect.

[0006] A large-scale ore microwave fracturing parameter adaptive control system includes: a dynamic microwave fracturing device, an ore transportation system, and an ore dynamic monitoring and parameter adaptive control system.

[0009] The ore dynamic monitoring and parameter adaptive control system includes a microwave power meter, an infrared thermal imager, a laser rangefinder, a PLC controller, and a host computer. The microwave power meter collects the microwave power reflected back to the waveguide from the ore surface and transmits the data to the host computer. The infrared thermal imager records the surface temperature of the ore after microwave transmission and transmits the data to the host computer. The laser rangefinder collects the contour information of the ore surface and transmits the data to the host computer. The PLC controller is connected to the microwave power supply, the rapid lifting device, the servo motor of the microwave radiator deflection device, and the ore transport system. The host computer calculates the microwave power, lifting height, deflection angle, and belt conveyor speed based on the collected information and sends this information to the PLC controller to achieve adaptive control of each parameter according to the ore size. Specifically, the lifting height and deflection device angle are adjusted by controlling the input microwave power, lifting height, deflection angle, and belt conveyor speed.

[0010] The host computer includes system control software that displays in real time the monitored rock surface temperature, lifting device displacement, deflection device displacement, vertical distance between the laser rangefinder and the ore, ore movement speed, input microwave power, and reflected microwave power. It can also control the lifting device displacement, deflection device displacement, ore movement speed, and input microwave power. The control is achieved through two modes: manual parameter setting and automatic control.

[0011] Furthermore, there are several laser rangefinders, which are set on a gate frame located s meters away from the microwave radiator. The gate frame is located upstream of the microwave radiator in the direction of ore movement. The laser rangefinders on the gate frame are evenly and symmetrically distributed, with the axis of symmetry coinciding with the axis of symmetry of the conveyor belt. They are arranged in multiple columns in the direction of ore movement, with each column containing less than or equal to B laser rangefinders. w / D w +2, where B w D is the width of the microwave radiator. w The minimum value of the width or thickness of a single laser rangefinder. The measuring points of the next column of laser rangefinders are located at the center between the measuring points of the previous columns. All laser rangefinders measure the vertical distance from the laser rangefinder to the ore.

[0012] Furthermore, the infrared thermal imager is located on a door frame 5-20 cm away from the microwave radiator. The door frame is downstream of the microwave radiator in the direction of ore movement and is placed in a microwave shielding box. The center of the infrared thermal imager is C meters away from the edge of the ore conveyor belt. w / 2 places, of which C w This refers to the width of the ore conveyor belt.

[0013] Furthermore, the microwave radiator deflection device includes a servo motor II, a pulley block, and a traction rope. The servo motor II and the pulley block are fixed on a rectangular right-angle waveguide, and the two ends of the traction rope are fixed on the microwave radiator.

[0015] Furthermore, the lower end of the vibration damper is connected to the lifting platform, and the upper end is connected to the microwave generator; the number of vibration dampers is greater than or equal to four.

[0016] Furthermore, the large-scale microwave fracturing parameter adaptive control system for ores is used to implement the following method, specifically including the following steps:

[0017] Step 1: Open the system control software on the host computer, return the microwave radiator to the safe position; set the safe distance to prevent the ore from colliding with the microwave radiator, the safe microwave power, the microwave power change rate, the reflection power threshold, the lower and upper limits of the ore fracturing temperature, and the initial transport speed v of the conveyor belt.

[0018] Step 2: Preheat the microwave equipment for 3-5 minutes. After preheating, turn on the microwave. The microwave power will increase to the safe microwave power according to the set speed. During the microwave power increase, the reflected power will be monitored in real time. If the reflected power exceeds the set threshold, the microwave power will be reduced until the reflected power is lower than the threshold and the microwave power will remain unchanged.

[0019] Step 3: Start the ore conveyor belt. After a s / v time, start adaptive parameter adjustment. The host computer will perform the following calculations and judgments:

[0020] Based on the height contour line of the ore within a length of s meters obtained by the laser rangefinder, a new contour line is generated by selecting the point with the maximum height at each location; within s / v time, the host computer will generate the motion trajectory of the microwave radiator based on the maximum height contour line of the ore, the safe distance between the ore and the microwave radiator, and the width of the microwave radiator. The host computer will transmit the commands to adjust the moving distance of the lifting device and the deflection angle of the deflection device to the PLC controller. The PLC controller controls the servo motor I of the rapid lifting device and the servo motor II of the microwave radiator deflection device to make the microwave radiator reach the target position.

[0021] If the ore temperature after microwave radiation is below the ore fracturing temperature threshold, and the microwave power is below the safe power, then increase the microwave power; if the microwave power reaches the safe power, then decrease the ore movement speed. If the ore temperature after microwave radiation is above the upper limit of ore temperature, and the microwave power is below the safe power, then decrease the microwave power; if the microwave power reaches the safe power, then increase the ore movement speed.

[0022] Throughout the entire process of moving the microwave radiator, adjusting the microwave power, and adjusting the ore transport speed, the reflected power must be kept below the threshold.

[0023] The beneficial effects of adopting the above technical solution are as follows:

This invention can automatically adjust the distance between the microwave radiator and the ore, the microwave output power, and the ore moving speed according to the size and shape of the ore, so as to ensure the best microwave fracturing effect and reduce the energy consumption of mechanical crushing of ore.

The laser rangefinder collects the contour information of the ore surface and transmits the data to the host computer. The PLC controller 24 is connected to the microwave power supply 1, the rapid lifting device, the servo motor of the microwave radiator deflection device, and the ore transport system. The host computer calculates the microwave power, lifting height, deflection angle, and belt conveyor speed based on the collected information and sends this information to the PLC controller 24 to achieve adaptive control of each parameter according to the ore size. Specifically, the lifting height and deflection device angle are adjusted by controlling the input microwave power, lifting height, deflection angle, and belt conveyor speed.

The servo motor II 12 has two independent rotors. The traction rope 14 is wound around the two rotors of the servo motor II 12 through the pulley block 13. The servo motor II 12 is connected to a PLC controller.

[0041] In this embodiment, as shown... Figure 4As shown, the microwave radiator deflection device includes a flexible rectangular waveguide 6, a microwave radiator 7, a servo motor II 12, a pulley block 13, and a traction rope 14. The two ends of the traction rope 14 are fixed to the microwave radiator 7. The traction rope 14 is wound around the two sets of rotors of the servo motor II 12 through the pulley block 13. The two sets of rotors of the servo motor II 12 control the traction rope 14 on both sides of the flexible rectangular waveguide 6, so that the microwave radiator 7 deflects.

[0042] Furthermore, the rapid lifting device is driven by a servo motor I11 and the lifting of the lifting platform 9 is controlled by a reducer. The servo motor I11 is connected to a PLC controller.

[0043] In this embodiment, the rapid lifting device adopts existing technology, including a servo motor I11, a reducer, a lifting platform 9, and a lead screw 10. The servo motor I11 drives the lead screw 10 to move through the reducer, so that the lifting platform 9 rises or falls.

[0045] Furthermore, the large-scale microwave fracturing parameter adaptive control system for ore is as follows: Figure 5 As shown, the method is used to implement the following steps:

[0046] Step 1: Open the system control software on the host computer and return the microwave radiator 7 to the safe position; set the safe distance to prevent the ore from colliding with the microwave radiator 7, the safe microwave power, the microwave power change rate, the reflection power threshold, the lower and upper limits of the ore fracturing temperature, and the initial transport speed v of the conveyor belt; where the safe microwave power refers to the highest power at which the microwave equipment can operate stably for a long time.

[0047] Step 2: Preheat the microwave equipment for 3-5 minutes. After preheating, turn on the microwave. The microwave power will increase to the safe microwave power according to the set speed. During the microwave power increase, the reflected power will be monitored in real time. If the reflected power exceeds the set threshold, the microwave power will be reduced until the reflected power is lower than the threshold and the microwave power will remain unchanged.

[0048] Step 3: Start the ore conveyor belt. After a s / v time, start adaptive parameter adjustment. The host computer will perform the following calculations and judgments:

Within s / v time, the host computer generates the motion trajectory of the microwave radiator 7 based on the maximum height contour of the ore, the safe distance between the ore and the microwave radiator 7, and the width of the microwave radiator 7. The host computer transmits the commands to adjust the moving distance of the lifting device and the deflection angle of the deflection device to the PLC controller. The PLC controller controls the servo motor I of the rapid lifting device and the servo motor II of the microwave radiator deflection device to make the microwave radiator 7 reach the target position.

[0050] If the ore temperature after microwave radiation is below the ore fracturing temperature threshold, and the microwave power is below the safe power, then increase the microwave power; if the microwave power reaches the safe power, then decrease the ore movement speed. If the ore temperature after microwave radiation is above the upper limit of ore temperature, and the microwave power is below the safe power, then decrease the microwave power; if the microwave power reaches the safe power, then increase the ore movement speed.

[0051] Throughout the entire process of moving the microwave radiator 7, adjusting the microwave power, and adjusting the ore transport speed, the reflected power must be kept below the threshold.

[0052] In this embodiment, in order to obtain the lower and upper limits of the ore fracturing temperature, the safe distance between the ore and microwave radiation, the target value of microwave power, and the target value of ore transportation speed, it is necessary to conduct microwave fracturing tests with different microwave powers, times, radiation distances, and ore sizes in advance. During the test, the surface temperature of the ore is monitored, and the ore is mechanically crushed after microwave radiation. The lower and upper limits of the ore fracturing temperature are obtained based on the relationship between the mechanical crushing effect of the ore after microwave radiation and the ore surface temperature and radiation distance. The target value of microwave power and the target value of ore transportation speed are obtained based on the relationship between the mechanical crushing effect of the ore after microwave radiation and the microwave power and radiation time.
