Problems solved by technology

[0005] However, most of the research on the mechanism of microwave rock breaking at home and abroad currently uses conventional industrial microwave ovens to carry out experiments, and even household microwave ovens. The equipment has a single function and cannot meet the relevant requirements of the test, and the reliability of the test results is low.

Embodiment Construction

[0033] Such as figure 1 , figure 2 As shown, the microwave rock breaking test device disclosed in this embodiment includes a casing 1, a microwave generator 2, a wave guiding path 3, a power meter 4, a wave absorbing system 5 and a cooling system.

[0034] The casing 1 is a rectangular parallelepiped casing. The casing is provided with a partition to separate an independent heating chamber 11 in the inner cavity, and the casing is provided with a door 12 to close the heating chamber, and a sealing ring 13 is arranged between the door and the body of the heating chamber to Anti-microwave leakage. Such as image 3 As shown, the heating chamber 11 is a hexagonal prism cavity; its bottom is provided with a tray 14, a tray bracket 15 and a motor 16, and a through hole is reserved in the center of the tray so that when the experiment needs to test the internal temperature of the rock mass, a temperature sensor such as a thermocouple can be connected. The bottom end of the tray ...

Abstract

The invention discloses a microwave rock-breaking experiment device. The microwave rock-breaking experiment device comprises a machine shell, microwave generators, guide wave paths, a wave absorptionsystem and a cooling system, wherein a partition plate is arranged in the machine shell and is used for partitioning an inner cavity into independent heating cavities, a plurality of wave feeding holes are formed in cavity walls of the heating cavities, the microwave generators and the guide wave paths are arranged in a set, the numbers of the microwave generators and the guide wave paths are matched with the numbers of the wave feeding holes, one end of each guide wave path is connected with the microwave generator, the other ends of the guide wave paths extend to the corresponding wave feeding holes, a power meter is arranged outside the guide wave paths, the wave absorption system comprises a water load, the water load is arranged outside a waveguide assembly and is used for absorbing energy for reflecting microwave, and the cooling system is arranged in the shell and at a region outside the heating cavities. During application, a rock sample is placed, the microwave generators arestarted, and microwave rock-breaking experiment device is applicable to various types of rock samples, the generated micro waves are transmitted to the rock sample through the guide wave paths so thatthe rock sample is broken, the power meter is used for testing microwave energy absorbed by the rock sample, the wave absorption system is used for absorbing the energy for reflecting the microwave,meanwhile, the cooling system is started to dissipate heat in the machine shell, and the experiment reliability is improved.

Description

technical field [0001] The invention belongs to the technical field of mining and geotechnical engineering test equipment, in particular to a microwave rock breaking test device. Background technique [0002] In mining and geotechnical engineering, especially in the field of metal ore hard rock mining, it is a goal that mining and engineering circles at home and abroad have been pursuing to find new rock-breaking methods to realize one-step continuous mining of ore bodies. In coal mining, the application of various continuous coal mining machines has successfully realized the continuous mining of soft rock. In the hard rock mining of metal ores, the traditional blasting method and mechanical rock breaking method still occupy a dominant position in the rock breaking method, reaching more than 90%. Although the blasting method has the advantages of high efficiency and mature technology in large-scale rock crushing projects, it will continue to exist for a long time at present...
