Abstract

The invention discloses an integrated device for powder preparation and powder mixing, and an application thereof. The integrated device for powder preparation and powder mixing comprises a medium-frequency smelting furnace, a heat-insulation furnace, an upper spray disc, a lower spray disc, a collection bucket and a powder spray device. The medium-frequency smelting furnace is a fixed-point casting furnace, and a casting center corresponds to the center of the heat-insulation furnace; and the lower spray disc and the upper spray disc are placed in an upper-end connector of the collection bucket, the lower spray disc is connected with a high-pressure water pipeline, the upper spray disc is connected with the powder spray device, the heat-insulation furnace is installed at the top of the upper spray disc, a discharge spout is formed in the bottom of the heat-insulation furnace, and the center of the discharge spout corresponds to the centers of the spray discs. The lower end of the collection bucket is connected with a filter-pressing bucket, and a butterfly valve is arranged between the collection bucket and the filter-pressing bucket. According to the integrated device for powderpreparation and powder mixing, and the application thereof, the two actions of preparation and mixing for metal powder are realized on one piece of equipment, and the integrated device for powder preparation and powder mixing is simple and convenient to operate, high in production efficiency, and low in labor intensity; and moreover, the distribution uniformity and the bonding strength of dispersion-strengthening-phase particles or high-melting-point-phase particles in a matrix material are improved and increased, and the integrated device for powder preparation and powder mixing is simple inprocess path, short in processing flow, and suitable for large-batch production.

Description

technical field [0001] The invention relates to the field of material powder processing equipment, specifically a powder preparation and powder mixing integrated device, especially based on high-pressure water atomization equipment, which simultaneously realizes the preparation of matrix material powder and the matrix material powder and dispersion strengthening phase Powder preparation-powder mixing integrated equipment system for uniform powder mixing. Background technique [0002] Powder metallurgy is an industrial technology for producing metal powder and using metal powder (or a mixture of metal powder and non-metal powder) as raw materials, through powder mixing, forming and sintering, to produce metal materials, composite materials and various types of products. At present, powder metallurgy technology has been widely used in transportation, machinery, electronics, aerospace, weapons, biology, new energy, information and nuclear industries, and has become one of the m...

AI Technical Summary

Problems solved by technology

The main disadvantages of this processing method are: the processing cycle is long, and two processes are required to complete the preparation of the mixed powder; the bonding strength between the matrix material and the dispersion-strengthened phase is low; the density between the matrix material and the dispersion-strengthened phase material When the difference ratio is large, the distribution uniformity of the dispersion strengthening phase in the matrix material is poor

However, this method brings new problems: the processing cycle is longer, and the preparation method is more cumbersome; the manufacturing cost is higher than that of atomized powder milling-mechanical mixing; a large amount of acidic / alkaline wastewater is produced in the chemical method production process, which is harmful to The pollution of the environment is relatively serious, and the cost of environmental protection treatment is very high

[0006] The inventor has consulted relevant patents at home and abroad and knows that the current equipment design scheme is still based on separate atomization equipment and mechanical powder mixing equipment, and has not found a single equipment that realizes the physical method of powder making-powder mixing integrated equipment. the case
