Description

Technical Field

[0001] The invention relates to the technical field of deep processing of sponge copper, in particular to equipment for preparing sponge copper and a preparation method thereof. Background Art

[0002] Pure copper is a soft metal with a yellow or purple surface, good ductility, high thermal and electrical conductivity, and is therefore the most commonly used material for electronic and cable electrical components. Copper alloys are also widely used in mechanical manufacturing, but with the rapid development of science and technology, the application of copper at a higher level has become a major topic that several developed countries in Europe are competing to develop and keep highly confidential. At present, with the successful development of the new material foam aluminum and its mass production in several developed countries in Europe, its many functions have been fully utilized in many fields, such as its buffering function, sound absorption function, flame retardant function and light weight. However, the development and demand of science are endless, with the rapid development and application of artificial intelligence and the gradual improvement of people's awareness of traffic safety.

[0003] At present, it is only limited to a concept and laboratory stage, and has not really achieved mass production. The fundamental reasons are reflected in two aspects. First, no equipment that can achieve mass production has been developed. Although the process flows are roughly the same, the development of equipment is the biggest obstacle facing experts around the world. Second, because the melting point of copper is about 1080 degrees, the temperature with better fluidity is about 1300 degrees. Because the foaming agent is a hydrogen-titanium compound (T i H2) formed by covalent bonds of hydrogen and titanium under high temperature and high pressure, their combination is originally a very unstable compound and is easily decomposed when exposed to high temperature. Because the hydrogen element in the foaming agent can only decompose and foam normally between 750 and 900 degrees, when the foaming agent encounters a high temperature above 1000 degrees, it will evaporate instantly at high temperature and cannot play its normal foaming function. When the temperature of the copper water is lower than 1000 degrees, it is in a rapid crystallization state below the critical point, and the foaming agent will also be blocked and cannot function normally. Therefore, a person skilled in the art provides an apparatus for preparing sponge copper and a preparation method thereof to solve the problems raised in the above background technology. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a device for preparing sponge copper and a preparation method thereof, which solve the problem that, first, no equipment that can achieve mass production has been developed, although the process flows are roughly the same, the development of equipment is the biggest obstacle facing experts around the world; second, because the melting point of copper is about 1080 degrees, the temperature with better fluidity is about 1300 degrees, and because the foaming agent is a hydrogen-titanium compound (TiH2) formed by covalent bonds of hydrogen and titanium under high temperature and high pressure, their combination is originally a very unstable compound, which is easily decomposed when exposed to high temperature, because the hydrogen element in the foaming agent can only decompose and foam normally between 750 and 900 degrees, when the foaming agent encounters a high temperature above 1000 degrees, it will evaporate instantly at high temperature and cannot play its normal foaming function. When the temperature of the molten copper is lower than 1000 degrees, it is in a rapid crystallization state below the critical point, and the foaming agent will also be blocked and cannot play its normal role.

[0022] 1. In the present invention, the smelting structure of the uppermost layer can simultaneously meet the production capacity of the four microporous batchers of the lower layer, so its comprehensive production capacity is 4 times that of the imported similar production process and equipment. Since the four microporous batchers on the middle turntable are in the rotating state of the four-station divider, 4 times the mass production can be completed at one time, eliminating the process of transporting the molten copper back and forth from the molten copper bag, saving labor and time and realizing safe production.

[0023] 2. In the present invention, the copper alloy is realized in four microporous batchers in the next process. Since the melting points of aluminum powder, lead powder and tin powder are all below 660 degrees, they can quickly absorb the temperature of the copper liquid and become liquid, and solve the problem of rapid cooling of the copper liquid. The second agitator rotates rapidly and cooperates with the spiral structure to move the liquid up and down to complete the preparation and rapid cooling of the alloy. The activity of aluminum, lead and tin liquids inhibits the crystallization rate of the copper liquid.

[0024] 3. In the present invention, the first agitator completes the reasonable delivery of the foaming agent, absorbs the energy of the copper liquid again and realizes rapid stirring and cooling. Since the copper liquid is always in a high-speed rotating state, the copper liquid is still in a liquid state when it is nearly 200 degrees below the critical point of crystallization.

[0025] 4. In the present invention, since the four batching barrels on the second intermediate rotating platform are provided with spiral devices, the liquid can be reasonably distributed by circulating up and down, providing mutual dissolution between atomic nuclei of copper alloy elements and controlling the overflow of other alloys.
