Sieving and drying device for metal powder

Abstract

The invention discloses a sieving and drying device for metal powder, include a hot air fan, sieve powder box, distribution box and dispersing box, An upper end of that dispersion box is provide witha motor 2 and a feeding port, A taper stirring drum is arrange in that dispersion box, the main shaft of the motor 2 is provided with a stirring shaft, the lower end of the conical stirring drum is provided with a blanking pipe, A low end of that blanking pipe is communicate with the distribution box, A control valve is arranged on the feeding pipe, A run wheel is arranged in the material distribution box, two grooves are symmetrically arranged on the runner, the upper end side of the sieve powder box is provided with a mounting seat, A motor 1 is arranged on the mounting seat, the main shaftof the motor is provided with an eccentric wheel, A screen net frame is arranged in the screen powder box, a screen net is arranged on the inner side of the screen net frame, a bracket is arranged onthe bottom of the screen powder box, and a recovery box is arranged on the upper end of the bracket. The device realizes the quantitative screening of the powder, ensures the screening effect and efficiency of the screen net, and the treated powder contains less impurities and the water content of the powder is low.

Description

technical field [0001] The invention belongs to the technical field of metal powder processing, in particular, the invention relates to a screening and drying device for metal powder. Background technique [0002] Metal powder is generally obtained by ball mill grinding for a certain period of time. During grinding, metal and water are mixed into the ball mill, and then the ball mill is started to crush the metal by the grinding body. The crushed metal powder needs to be dehydrated. The dehydrated powder needs Screening, the traditional screening equipment directly pours the powder into the vibrating screen, without considering the influence of the weight of the metal powder on the screen, too much powder, the screen is under too much pressure, the aperture is enlarged, and the screening effect is reduced , too little powder, the screening efficiency is reduced. [0003] The existing patent 204584279 discloses a metal powder crushing and screening device belonging to the te...

[0002] Metal powder is generally obtained by ball mill grinding for a certain period of time. During grinding, metal and water are mixed into the ball mill, and then the ball mill is started to crush the metal by the grinding body. The crushed metal powder needs to be dehydrated. The dehydrated powder needs Screening, the traditional screening equipment directly pours the powder into the vibrating screen, without considering the influence of the weight of the metal powder on the screen, too much powder, the screen is under too much pressure, the aperture is enlarged, and the screening effect is reduced , too little powder, the screening efficiency is reduced

[0003] The existing patent 204584279 discloses a metal powder crushing and screening device belonging to the technical field of metal powder crushing and screening, including a hopper, a crusher, a classifier, a vibrating screen, a storage tank, a dust collector, and an induced draft fan; among them, The feed hopper is connected to the crusher by welding; the discharge port of the crusher is connected to the flange of the classifier through a pipe; The outlet of the classifier is connected to the storage barrel through a hose; the air outlet of the classifier is connected to the flange of the dust collector through a pipe; the air inlet of the dust collector is connected to the induced fan through a pipe, and this device realizes the crushing and screening of powder , but the influence of the powder on the screen is not considered during screening. The present invention proposes a screening and drying device with multiple functions and good screening effect and efficiency.
