Embodiment 1

[0035] Please refer to Figure 1~2 , the present embodiment discloses a fluid mixer 0100, the main part of the fluid mixer 0100 includes a mixer housing 0110 for achieving uniform mixing of fluids. The mixer housing 0110 is provided with a mixing chamber 0114, which is the main place for fluid mixing. The mixer housing 0110 includes a front wall 0111 , a rear wall 0112 and a peripheral wall 0113 . The front wall 0111 and the rear wall 0112 are arranged opposite to each other and connected by the peripheral wall 0113 . The three surround and form a mixing chamber 0114 .

[0036] A fluid input port 0120 is provided on the front wall 0111 for inputting fluid into the mixing chamber 0114 . Since the front wall 0111 is kept opposite to the rear wall 0112, the fluid input end 0120 is also kept opposite to the rear wall 0112, so that the fluid input from the fluid input end 0120 impacts the rear wall 0112, thereby increasing the velocity gradient of the fluid or forming turbulent fl...

Embodiment 2

[0049] Please refer to Figure 3-4 , on the basis of Embodiment 1, this embodiment discloses a flow guiding device 1000 , including a fluid mixer 0100 and a flow guiding converter 0200 . Wherein, the fluid output end 0130 of the fluid mixer 0100 is matched with the input end of the diversion converter 0200 (ie, the diversion input end 0211 ). The fluid mixer 0100 is used to achieve uniform mixing of fluids to obtain a mixed fluid, and the diversion converter 0200 is used to reduce the turbulence of the mixed fluid to a preset range.

[0050] It should be noted that when the flow guiding device 1000 is applied to 3D printing equipment, the shielding gas in the processing chamber of the equipment can have the following characteristics: first, the shielding gas has turbulent characteristics, enough to make it compatible with smoke, volatiles, powder Material fines are fully mixed and discharged to clean the processing chamber; second, the turbulence of the protective gas should ...

Abstract

The invention relates to a fluid mixer, which comprises a mixer shell. The mixer shell comprises a front wall, a rear wall and a peripheral wall; the front wall and the rear wall are arranged oppositely and are connected through the peripheral wall so as to form a mixing chamber; a fluid input end is arranged on the front wall; a fluid output end is arranged on the peripheral wall; the fluid inputend is perpendicular to the fluid output end. A flow guiding device comprises a flow guiding converter and the fluid mixer. The fluid output end is connected with an input end of the flow guiding converter in a matching way; the fluid mixer is used for uniformly mixing a fluid so as to obtain a mixed fluid; the flow guiding converter is used for lowing the turbulivity of the mixed fluid to a preset range. According to the fluid mixer and the flow guiding device provided by the invention, the fluid can be uniformly mixed so as to be fully mixed, uniform in composition and ideal in turbulivity,the occurrence of the phenomenon of diffused flying of pollutants is reduced, and the sintering processing efficiency is ensured.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, specifically, a fluid mixer and a flow guiding device. Background technique [0002] Additive Manufacturing (AM), commonly known as 3D printing, is a fusion of computer-aided design, material processing and forming technology, based on digital model files, through software and numerical control system to combine special metal materials, non-metal materials and medical biological Materials are piled up layer by layer according to extrusion, sintering, melting, photocuring, spraying, etc., to create a manufacturing technology for physical objects. [0003] Among them, selective laser sintering (Selective Laser Sintering) is an important additive manufacturing method. The principle is that the laser beam selectively sinters the powder material layer by layer according to the layered cross-section information, and after all the sintering is completed, the excess powder is removed to ob...
