[0017] Figure 2 It is a structural schematic view of the 3D light scanning machine flour liquid recycling device. Figure 1 It is an enlarged schematic view of part A. DETAILED DESCRIPTION

[0018] The specific embodiments of the utility model will be described in detail below with reference to the drawings.

[0019] Referring to Figure 1 , the 3D light scanning machine flour liquid recycling device comprises a flour liquid separation tank 1 and a flour liquid collection tank 5, the top of the flour liquid separation tank 1 is provided with a feed pipe 11 connected in communication with the tail end of a machine vacuum pipe 2 and a gas outlet pipe 12 connected in communication with a machine vacuum pump 3, the bottom of the flour liquid separation tank 1 is provided with a discharge port 13, the discharge port 13 is connected in communication with the flour liquid collection tank 5 located below the flour liquid separation tank 1 through a discharge pipeline 4, a switch valve 6 is connected on the discharge pipeline 4, and the flour liquid collection tank 5 is also connected in communication with a machine flour liquid tank through a conveying pipeline 51.

[0020] When the airflow entrains the abrasive liquid in the machine vacuum pipe 2 enters the abrasive liquid separation tank 1 through the feed pipe 11, the abrasive liquid will fall into the abrasive liquid separation tank 1 by gravity due to the density of the abrasive liquid being greater than the density of the gas, and the gas will be continuously pumped out by the vacuum pump 3 connected to the gas outlet pipe 12 and discharged into the atmosphere, realizing the separation of the abrasive liquid and the gas. When the abrasive liquid in the abrasive liquid separation tank 1 accumulates to a certain amount, the switch valve 6 is opened, and the 3D scanning machine stops scanning work, the abrasive liquid is discharged into the abrasive liquid collection tank 5, and the abrasive liquid in the abrasive liquid collection tank 5 is transported to the machine abrasive liquid tank through the conveying pipeline 51, and then the switch valve 6 is closed, and the 3D scanning machine can continue to work, thereby realizing the recycling of the abrasive liquid.

[0021] The 3D scanning machine abrasive liquid recycling device not only saves abrasive liquid and reduces production cost, but also greatly reduces the frequency of manually adding abrasive liquid to the 3D scanning machine, reduces labor intensity, and ensures production stability and working reliability of the 3D scanning machine.

[0022] A plurality of baffles 14 connected to the top wall and the bottom wall inside the abrasive liquid separation tank 1 are arranged between the feed pipe 11 and the gas outlet pipe 12 of the abrasive liquid separation tank. Each baffle 14 connected to the bottom wall of the abrasive liquid separation tank 1 is provided with a flow-through groove 141 penetrating the baffle 14 near the bottom of the baffle 14.

[0023] When the airflow entrains the abrasive liquid enters the abrasive liquid separation tank 1 through the feed pipe 11, it will collide with the upper and lower staggered baffles 14. The gas will bypass the baffles 14 and be extracted into the atmosphere through the gas outlet pipe 12 and the vacuum pump 3, while the abrasive liquid will be intercepted on the baffles 14 and fall into the abrasive liquid separation tank 1. The baffles 14 enhance the working reliability of the recycling device.

[0024] Reference Figure 1 , Figure 2 A screen 15 is arranged at the inlet of the gas outlet pipe 12. The aperture of the screen 15 is smaller than the particle size of the abrasive liquid. The screen 15 can prevent the abrasive from being extracted by the vacuum pump 3 through the gas outlet pipe 12, further increasing the working reliability of the recycling device.

[0025] The discharge pipeline 4 is connected to the air compressor 7. The high-pressure gas discharged by the air compressor 7 can forcefully blow the abrasive liquid in the discharge pipeline 4 into the abrasive liquid collection tank 5.

[0026] A transparent material level observation window 8 is arranged on the side wall of the abrasive liquid separation tank 1, which facilitates the operator to observe the level of the abrasive liquid in the abrasive liquid separation tank 1.

[0027] The bottom of the ground powder liquid separation tank 1 is a conical structure 16 with a large upper part and a small lower part, facilitating the flow of ground powder liquid to the discharge port 131 at the bottom of the ground powder liquid separation tank 1, and a stainless steel leg structure 17 is arranged at the bottom of the ground powder liquid separation tank 1 to support it, so that the ground powder liquid collection tank 5 arranged below has an upper and lower height difference.

[0028] Since the working negative pressure of the vacuum pump is about -60kpa~ -80kpa, the ground powder liquid separation tank 1 made of polyethylene material with a wall thickness of 5mm can meet the strength requirement, the material is economical and durable, and is easy to process.

[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
