Powder passivation device

Abstract

The invention discloses a powder passivation device which comprises a frame and a passivation tank. The frame is supported by a frame group welding piece. An outer panel is arranged outside a mechanical group welding piece. Two rotation shaft brackets are arranged at the upper part of the frame. A rotation shaft is connected between the rotation shaft brackets. Both ends of the rotation shaft are sleeved by limit blocks. A number of respectively leveling bolts are arranged at the bottom of the frame. A speed control switch panel is arranged on the outer panel of the frame. A motor and a gearbox are arranged inside the frame. The passivation tank comprises a cylinder body. Flipping flanges are arranged on both ends of the cylinder body. A top sealing device is arranged in the middle part of the flipping flange at the upper part of the cylinder body. The bottom of the cylinder body is supported by a number of brackets. An inlet, outlet and filtration system joint is arranged at the bottom side of the cylinder body. A discharge valve is arranged in the opening at the bottom of the cylinder body. The powder passivation device provided by the invention can be applied to fine powder with poor fluidity, and has the functions of convenient transport, feeding and discharging. Universal wheels are arranged at the bottom of the passivation tank, which is convenient for moving.

Description

technical field [0001] The invention belongs to the fields of powder metallurgy, powder processing and preparation, and in particular relates to a powder passivation device. Background technique [0002] With the development of powder metallurgy and powder processing and preparation industries at home and abroad, more and more traditional craft products (such as castings, forgings, etc.) are gradually being replaced by powder materials. In these industries, powders need to be prepared and processed in various ways, such as mixing, refining, etc., but as long as the metal powders are more active with oxygen and other gases, it is necessary to passivate them to make the powder particles A thinner oxide film is produced on the surface to achieve a certain stability and safety in the later processing. [0003] At present, there are two kinds of vertical and horizontal types at home and abroad, but they are not ideal in actual use. The domestic vertical type is not suitable for...

AI Technical Summary

Problems solved by technology

[0003] At present, there are two types of vertical type and horizontal type at home and abroad, but they are not ideal in actual use.

Domestic vertical type is not suitable for finer and poor fluidity powder

Although the horizontal type is used in foreign countries, it is still lacking in terms of ease of use. The devices or equipment they use for passivation only have the passivation function, and do not have the functions of convenient transfer and feeding and discharging.
