Embodiment 1

[0046] A 3D printing quartz sand waste sand recovery treatment device, comprising a feed hopper, the feed hopper is connected with a screening cylinder, the screening cylinder is provided with a sieve plate, and the bottom of the screening cylinder is connected with a first outlet A material trough, the side wall of the screening cylinder is located above the sieve plate and communicated with a second discharge trough, the second discharge trough is connected with a crushing mixer, and the discharge port of the crushing mixer is connected with a dissolving tank, and the dissolving The outlet of the tank is connected with a pickling box, the outlet of the pickling box is connected with a cleaning box, the first outlet is connected with the cleaning box, and the outlet of the cleaning box is connected with the ultrasonic cleaning machine. The feed port is connected, and the discharge port of the ultrasonic cleaning machine is connected with a dryer.

[0047] With this setting, t...

Embodiment 2

[0049] On the basis of Embodiment 1, the crushing mixer includes a housing, a driving motor is installed on the top wall of the housing, an output end of the driving motor is connected to a stirring shaft, and crushing blades are connected to the stirring shaft. Through this setting, the drive motor drives the stirring shaft to rotate, and the crushing blades on the stirring shaft follow the rotation to crush and disperse the sand blocks and sand grains in the waste sand.

Embodiment 3

[0051] On the basis of the above embodiments, there are multiple crushing blades, and the crushing blades are evenly distributed along the length direction of the stirring shaft. Through this setting, the contact surface between the crushing blade and the sand blocks and sand grains in the waste sand can be enlarged, and the efficiency of crushing and dispersing can be improved.

Abstract

The invention discloses a 3D printing quartz sand waste sand recycling device, belongs to the technical field of photocuring 3D printing, and aims to solve the problem of resource waste caused by the fact that existing 3D printing quartz sand waste sand is not recycled. The device comprises a feeding hopper, the feeding hopper is communicated with a screening barrel, a screening plate is arranged in the screening barrel, the bottom of the screening barrel is communicated with a first discharging groove, the portion, located above the screening plate, of the side wall of the screening barrel is communicated with a second discharging groove, the second discharging groove is communicated with a crushing and stirring machine, and a discharging opening of the crushing and stirring machine is communicated with a dissolving tank. A discharging port of the dissolving tank is communicated with an acid pickling box, a discharging port of the acid pickling box is communicated with a cleaning box, the first discharging groove is communicated with the cleaning box, a discharging port of the cleaning box is communicated with a feeding port of an ultrasonic cleaning machine, and a discharging port of the ultrasonic cleaning machine is communicated with a drying machine. The invention is suitable for the 3D printing quartz sand waste sand recovery treatment device.

Description

technical field [0001] The invention belongs to the technical field of light-curing 3D printing, and in particular relates to a 3D printing quartz sand waste sand recycling and processing device. Background technique [0002] 3D printing technology, that is, additive manufacturing technology, as an emerging manufacturing strategy, has received more and more attention. The combination of 3D printing with chemistry, engineering, materials, medicine and other fields is gradually changing the existing molding and application methods. 3D printing technology is based on the rapid prototyping of digital model files, which breaks through the traditional prototyping mode. It achieves forming requirements by accumulating materials layer by layer from bottom to top, and can quickly realize complex structures that cannot be realized or are difficult to manufacture by traditional methods. Materials with a certain three-dimensional structure can be prepared by layer-by-layer printing, w...
