Technical Field

The invention relates to the field of screening machinery, in particular to a vibrating screen anti-blocking blanking hose for 3D printing metal powder production.

Background

The 3d printing metal powder is widely applied in the fields of aerospace and the like. In actual production, metal or alloy is melted and led out through a special guide pipe, and high-speed airflow is sprayed at the guide pipe to atomize the metal to form particles with very small particle size. And cooling and screening to select particles in the required particle size range. Therefore, sieving is an important ring in 3d printing technology powder production.

The screening equipment used at the present stage is basically an ultrasonic vibration screen. The ultrasonic generator enables the screen and the material to generate high-frequency vibration, so that the screening efficiency is improved. And then conveyed into the container through a blanking pipe.

Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.

As shown in fig. 1 to fig. 2, an anti-blocking discharging hose 10 for a vibrating screen for producing 3D printed metal powder according to an embodiment of the present invention includes a hard retainer 13, a hard section 11, and a flexible extension section 12, where the hard section 11 and the flexible extension section 12 are sequentially connected, an end of the hard section 11 at the uppermost end, which is far from the flexible extension section 12, is connected to a discharge port of the vibrating screen, and one end of the hard retainer 13 is connected to a connection between the hard section 11 and the flexible extension section 12, and the other end covers another connection between the hard section 11 and the flexible extension section 12 and can move in a discharging direction.

Further, the upper end of the hard retainer ring 13 is connected to the connection between the upper end of the flexible extending section 12 and the hard section 11, and the lower end of the hard retainer ring covers the other connection between the hard section 11 and the flexible extending section 12, that is, the flexible extending section 12 has an upper end and a lower end, the upper end of the hard retainer ring is connected to the lower end of the previous hard section 11, and the lower end of the hard retainer ring 13 is connected to the upper end of the next hard section 11, the upper end of the hard retainer ring 13 is connected to the connection between the upper end of one flexible extending section 12 and the hard section 11, and the lower end of the hard retainer ring 13 extends to cover the connection between the flexible extending section 12 and the hard section 11, so that a small gap can be formed between the hard retainer ring and the hard section 11, and the hard retainer ring 13 can be attached to. Because the lower extreme of hard retaining ring 13 is the expansion end, the expansion end can prevent to fall into between hard retaining ring 13 and flexible extension section 12 when the metal powder whereabouts downwards to influence the result of use.

Further, the device comprises a pulse device which comprises a pulse pipe used for being connected with an external air source and a pulse electromagnetic valve 20 arranged on the pulse pipe, wherein the pulse pipe penetrates into the hose 10, an inlet 21 of the pulse pipe is inclined downwards, and the pulse electromagnetic valve 20 is used for controlling the high-pressure air to be periodically blown into the hose. The pulse solenoid valve 20 can control external atmospheric pressure and produce periodic pulse air current, thereby pulse air current can produce great atmospheric pressure and assault the pipeline, thereby the pipeline is stretched with the help of flexible extension section 12 under the impact of atmospheric pressure, thereby the in-process material production of extension increases mobility with the section, avoids the jam of material.

Further, the high-pressure gas is an inert gas. The inert gas can prevent the oxidation of the metal powder and avoid the increase of the oxygen content of the metal powder.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
