Integrated powder mixing vacuum drying device and powder mixing drying system

Abstract

The invention provides an integrated powder mixing and vacuum drying device and a powder mixing and drying system, and relates to the technical field of powder mixing equipment. The device comprises adevice base and a device body. The device body is rotationally arranged on the device base and comprises a shell, a powder mixing cylinder, an ordinary gear train, a driving motor and an air-tight connector. The driving motor and the ordinary gear train are fixed into the shell, and the driving motor is in transmission connection with the powder mixing cylinder through the ordinary gear train. The powder mixing cylinder comprises a center powder mixing roll, and the ordinary gear train comprises a first connecting shaft. The center powder mixing roll and the first connecting shaft form an airchannel, and the air channel can communicate with a vacuum pump through the airtight connector. The powder mixing and drying system comprises the vacuum pump and the integrated powder mixing and vacuum drying device. According to the integrated powder mixing and vacuum drying device and the powder mixing and drying system, even mixing and synchronous drying actions on metal powder and ceramic powder or different alloy system powder are completed at the same time.

Description

technical field [0001] The invention relates to the technical field of powder mixing equipment, in particular to an integrated powder mixing vacuum drying device and a powder mixing drying system. Background technique [0002] Thermal spraying, surfacing, and laser cladding processes can prepare high-performance or special-function coatings on the surface of low-performance materials, and have been widely used in surface strengthening and modification of low-performance materials and key components. The function of the coating has been developed from the traditional anti-wear, anti-corrosion, anti-oxidation coating to anti-erosion, anti-impact, heat insulation and other special functions. A single coating material can no longer meet all the above purposes and uses, and the coating material system has also developed from a single metal powder, ceramic powder to composite powder, and gradually from the initial selection of iron-based, nickel-based and cobalt-based self-fluxing...

AI Technical Summary

Problems solved by technology

At present, there is no production equipment specially designed for the mixing of small batches of various types of powders on the market. Powder production and preparation manufacturers often use special equipment for batch production. The powder ratio is single and fixed, and the equipment is bulky.

In actual industrial application and scientific research, in order to optimize the process, it is necessary to purchase powder from the powder manufacturer for secondary blending. At present, manual shaking and mixing are usually used, and mechanical mixing is also performed by modifying a juicer or soybean milk machine. However, the above method has the disadvantages of low mixing efficiency, uneven mixing, easy moisture and oxidation, and potential safety hazards.
