Machining device for metal powder production

Abstract

A machining device for metal powder production comprises a tank body, an atomization rotating disc arranged at the upper end of the tank body and a discharging opening formed in the lower end of the tank body. The cooling structure is arranged on the inner wall of the tank body and is used for cooling and solidifying metal liquid drops sprayed out of the atomizing rotating disc; the screening structure is arranged in the tank body and is used for screening cooled and solidified metal powder; and the recovery structure is arranged on the inner bottom surface of the tank body and is used for collecting the large-particle-size metal powder positioned at the upper end of the screening structure. By arranging the cooling structure, the screening structure and the recycling structure, the forming rate of the metal powder can be increased, the formed metal powder can be preliminarily screened, and meanwhile, the unqualified large-particle-size metal powder can be recycled; the device integrates forming, screening and recycling in one tank body, and has the advantages of simplicity in operation, high production efficiency, good powder forming rate, high economic benefit and the like.

Description

technical field [0001] The invention belongs to the technical field of metal powder processing, and in particular relates to a processing device for metal powder production. Background technique [0002] Cuprous chloride is a catalyst widely used in the organic synthesis industry. Under its catalysis, it can produce a variety of organic chemical products, such as vinyl acetylene, chlorobutadiene, acrylonitrile, methyl chlorosilane, etc. Especially in the production of methylchlorosilane mixed monomers in the organosilicon industry, it is almost a necessary catalyst. In the petrochemical industry, cuprous chloride is also commonly used as a decolorizer, desulfurizer and release agent, and is mainly used as a catalyst and reducing agent in the oleochemical industry. [0003] At present, there are mainly atomization methods for the preparation of cuprous chloride powder. For example, Japanese patent JP2002234731 describes a method of producing spherical cuprous chloride by ga...

Problems solved by technology

[0004] However, after the atomized droplets are sprayed out from the nozzles of the atomizing turntable, they still have a relatively high linear velocity, so the droplets are easy to hit the inner wall of the device after being sprayed out, which eventually leads to a low spheroidization rate of the final formed powder. question

One of the ways to solve this problem is to expand the inner diameter of the device, but due to different atomization treatment conditions, the linear velocity of the sprayed droplets is different, and the method of changing the inner diameter of the device is not flexible and changeable, and the device with a larger inner diameter also has occupancy. big space problem

At the same time, the particle size distribution of the formed metal powder is different, and subsequent screening process is required. Due to the characteristics of cuprous chloride, a closed space needs to be kept during the screening process, which requires high equipment and high cost.
