Description

Technical Field

[0001] The present invention relates to the technical field of diamond crushing, and particularly to an operation method for a diamond liquid-electric crushing device. Background Art

[0002] Under the action of a high-voltage electric field, electrons in the liquid between the electrodes are accelerated and ionize the liquid molecules near the electrodes. The electrons ionized in the liquid are accelerated by the strong electric field between the electrodes to ionize more electrons, forming an electron avalanche, and a plasma channel is formed in the region where the liquid molecules are ionized. As the ionization region expands, a discharge channel is formed between the electrodes, the liquid is broken down, and the discharge current heats the liquid around the channel, causing the liquid to vaporize and expand rapidly outward. The outer edge of the rapidly expanding air cavity generates a powerful shock wave in the water medium. The shock wave acts on the surrounding medium in the form of impulse or impact pressure according to different discharge currents and discharge times. This phenomenon is called the liquid-electric effect. The liquid-electric effect is often used in aspects such as crushing, forming, forging, cutting, drilling, offshore exploration, and medical devices because it consumes less energy and only requires two materials, water and electricity.

[0003] Diamond is a mineral composed of carbon elements, an allotrope of carbon elements, and also a particle substance composed of elemental substances in nature. It is the hardest substance found in many natural existences on the earth at present and has a wide range of applications in life. At present, there are mainly two ways to crush diamond. One is wind grinding, which realizes the crushing of diamond by the collision of high-pressure air in a wind mill; the other way is ball milling, where diamond raw materials are added into a ball mill, and the crushing of diamond raw materials is realized by the rolling and impact of grinding balls in a crushing drum. These two common crushing devices have the following deficiencies when crushing diamond:

The water outlet of the circulation pump 14 is fixedly communicated with a circulation pipe 6. The top end of the circulation pipe 6 is fixedly communicated with the inside of the crusher housing 1;

[0038] During use, taking the positive electrode core column 15 as the positive electrode and the negative crushing cylinder 16 as the negative electrode, a pulsed current is continuously introduced into the crusher housing 1. The diamond raw materials are added through the feeding hopper 9. Under the action of gravity, the diamond raw materials fall into the negative crushing cylinder 16. A discharge channel is formed between the positive electrode core column 15 and the negative crushing cylinder 16. The liquid is broken down. The discharge current heats the liquid around the channel, vaporizes the liquid and rapidly expands outward. The outer edge of the rapidly expanding air cavity generates a powerful shock wave in the water medium to crush the diamond raw materials therein.
