Embodiment Construction

[0015] The present invention will be further described below in conjunction with accompanying drawing:

[0016] A device for recycling 3D printing waste metal powder, such as figure 1 As shown, it includes breaking up equipment 1, sorting equipment 14, iron removal equipment 8, collection equipment 9, 11 and gas supply equipment, wherein breaking up equipment such as figure 2 It consists of a breaking disc 1.3 and an inclined counterattack plate 1.4. The breaking disc 1.3 is driven by a motor 1.2. The surface of the inclined counterattack plate 1.4 is processed with triangular rib-shaped protrusions. The triangular rib-shaped protrusions on the inclined counterattack plate 1.4 can increase the The impact on the powder particles is to separate the metal powder bonded together due to the moisture in the air or other factors as much as possible; the vibrating screen 2 is set under the inclined counter-attack plate 1.4 to disperse the periphery of the equipment 1 A sound insulat...

Abstract

The invention provides a device for recovering waste metal powder in 3D printing. The device comprises scattering equipment, separation equipment, iron removing equipment, collecting equipment and gassupply equipment, wherein the scattering equipment is connected with the separation equipment through a discharging scraper-through conveyer, the separation equipment is provided with a radial gas inlet to be connected with the gas supply equipment, the upper part of the separation equipment is connected with an inlet of the iron removing equipment through a pipeline, an outlet of the iron removing equipment is connected with a cyclone separator through a pipeline, an outlet of the cyclone separator is connected with a pulse bag type dust collector, an gas outlet is arranged at the tail end of the pulse bag type dust collector, and the gas outlet and the gas supply equipment form a circulating protection gas loop through a pipeline. By the aid of the device, the problem of waste of wastepowder of 3D metal printing equipment is solved, resources are saved, the cost of 3D metal printing is reduced, and high-efficiency and high-quality recovery of the 3D metal printing equipment is realized.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and relates to a device for recycling 3D printing waste metal powder. Background technique [0002] In recent years, with the development of the manufacturing industry, metal material 3D printing technology, as an advanced manufacturing technology with high development potential, has attracted the attention of many scientific research institutions and businesses. [0003] Almost all metal material 3D printing equipment will produce a large amount of waste metal powder after printing, and these equipment often do not have corresponding waste powder treatment equipment, just simply discharge, and the discharged metal powder will be wasted due to purity problems, and due to the use of Due to the high production cost and high selling price of metal powder for 3D printing of metal materials, there is an urgent need for a device that can recycle and purify the waste metal powder of metal ...
