Abstract
An ultrasonic vibration screen with an inertia gas protection system comprises a raw material tank which is communicated with a screen body. A gas tube is communicated with an Ar source tank through a gas valve A. A gas guide tube is connected with the screen body. The gas valve A, a gas valve B and an oxygen analysis instrument are connected with a central processing unit. The oxygen analysis instrument is arranged in the screen body. An ultrasonic generation unit is connected with the screen body, and two outlets in the screen body are connected with a power collection tank A and a powder collection tank B respectively. The remaining oxygen limit is set, and a ball valve B, a ball valve C and a ball valve E are closed. The Ar gas enters the screen body, air in the screen body is discharged, the oxygen analysis instrument transmits detection data to the central processing unit, and the gas valve A and the gas valve B are closed when the set numerical value is reached. When the data are higher than the set limit values, oxygen reaches the set limit value, the gas valve A and the gas valve B are closed, and the gas valve A is opened, the ultrasonic generation unit is started, and screening is started. By means of the system, clustering and oxidation during ultrafine powder screening are prevented.
Description
Technical field
The invention belongs to the material sieving technology field of powder post processing, be specifically related to the ultrasonic vibrating screen being with inert gas protection system, be applicable to the screening of the submicron metal be very easily oxidized.
Background technology
Metal dust can adopt vibratory sieve and airflow screen to carry out screening process, vibratory sieve does exciting source by motor, motor upper/lower terminal is provided with eccentric hammer, is level, vertical, the three-D motion of tilting by the converting rotary motion of motor, then this Movement transmit to compass screen surface.Regulate the phase angle of upper/lower terminal, the movement locus of material on compass screen surface can be changed, thus make powder be penetrated screen cloth, reach the effect of screening.When superfines needs screening, because powder more carefully there will be agglomeration, not easily penetrate screen cloth, therefore adopt airflow screen to sieve.Airflow screen adopts air to make carrier, the operating principle of kinetic energy work done, after being mixed with air by material by negative-pressure air-flow, enter in the middle of screen(ing) machine wind wheel, apply enough centrifugal force by wind wheel blade, sprayed net to barrel-shaped screen cloth, collect through spiral case, realize the screening of fine powder.Above-mentioned two kinds of methods all cannot avoid the contact of sieved powder and air, when sieved powder is very easily oxidized, such as titanium or titanium alloy powder, just there will be the generation of powder at screening process oxidative phenomena, be difficult to ensure powder quality.
Summary of the invention
For overcoming above-mentioned the deficiencies in the prior art, the object of the invention is to provide a kind of ultrasonic vibrating screen with inert gas protection system, occurs reunion, oxidative phenomena when avoiding superfine powder to sieve.
For achieving the above object, the technical solution used in the present invention is: a kind of ultrasonic vibrating screen with inert gas protection system, includes raw material batch can, and raw material batch can is connected with the pipe of sieve body upper end with ball valve B by the ball valve A of its end; Tracheae is communicated with by air valve A with Ar source of the gas tank; Wireway is connected with sieve body by air valve B; Air valve A, air valve B and oxygen analyzer are connected with central controller; Oxygen analyzer is positioned in sieve body; Ultrasonic generator is connected with sieve body, and sieve body is placed on support; Sieve body is provided with two outlets, and an outlet is connected with the receipts powder material tank A with ball valve D by ball valve C; Another outlet is connected with the receipts powder material tank B with ball valve F by ball valve E.
The invention has the beneficial effects as follows:
When adopting the ultrasonic vibrating screen of band inert gas protection system of the present invention to carry out powder sieving; in whole screening process; under powder is in the protection of Ar gas always; oxidative phenomena can not be there is; the quality of powder can be guaranteed; the ultrasonic generator increased applies ultrasonic vibration to screen cloth, thus enables powder quickly through screen cloth, avoids agglomeration and occurs.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, row of the present invention is described in detail.
See Fig. 1, raw material batch can 1 end connects with the pipe of sieve body 4 upper end with ball valve B3 with ball valve A2, tracheae 5 is connected by air valve A6 with Ar source of the gas tank 7, wireway 15 is connected with sieve body 4 by air valve B16, air valve A6, air valve B16 and oxygen analyzer 8 are connected with central controller 12, oxygen analyzer 8 is positioned in sieve body 4, and ultrasonic generator 14 is connected with sieve body, and sieve body is placed on support 13.Sieve body is provided with two outlets, and a port of export has ball valve C9 to be connected with the receipts powder material tank A11 with ball valve D10; Another port of export has ball valve E17 to be connected with the receipts powder material tank B19 with ball valve F18.
Operation principle: the powder sieved first as required sets the limiting value of remaining oxygen in central controller 12 to the sensitivity of oxygen, closes ball valve B3, ball valve C9 and ball valve E17.Then air valve A6 and air valve B16 is started by central controller 12, Ar gas enters in sieve body 4 by tracheae 5 from Ar source of the gas tank 7, air in sieve body 4 is discharged by tracheae 15, oxygen analyzer 8 is detecting that the data of the intrinsic remaining oxygen of sieve are transferred to central controller 12, when reaching the numerical value of setting, central controller sends instruction and closes gas check valve A6 and air valve B16.Raw material batch can 1, receipts powder material tank A11 and receipts powder material tank B19 are connected with sieve, open ball valve B3, ball valve C9, ball valve D10, ball valve E17 and ball valve F18, when the data that oxygen analyzer 8 transmits are higher than the limiting value set, air valve A6 and air valve B16 opens, until remaining oxygen reaches the limiting value of setting in sieve body, close gas check valve A6 and air valve B16.Open ball valve A2, and start ultrasonic generator 14, screening starts.After screening terminates, close ball valve D10 and ball valve F18, unload and receive powder material tank A11 and receive powder material tank B19, close ball valve B3 and ball valve 4 simultaneously, take off raw material batch can 1.
