Technical Field

[0002] Solid waste treatment devices and treatment processes are an important part of environmental engineering. Their purpose is to reduce the pollution of solid waste to the environment and realize the resource utilization, harmlessness and reduction of waste. In particular, 3D printing waste, which is mostly composed of materials such as plastics, metals, and ceramics, not only occupies a large amount of space, but is also difficult to decompose in the natural environment, and has a negative impact on the ecological environment that cannot be ignored. In particular, plastic waste, if not properly handled, will lead to soil and water pollution, and even pose a threat to human health through the food chain. When it is treated, it is generally treated by physical treatment, and it is put into the treatment device for crushing. However, the existing treatment device can only roughly crush it during the crushing process. After crushing, other devices must be used for re-grading treatment. The operation process is relatively troublesome. At the same time, there will be the disadvantages of waste splashing and dust raising during the operation, which will further cause harm to the surrounding environment and operators. In addition, if the amount of waste is large, the roller will crack or be damaged due to overheating when working for a long time.

[0015] S1. Start the motor first, and its output shaft will drive the first pulley to rotate through the coupling. The first pulley will drive the second pulley to rotate through the pulley. The second pulley will drive the rotating rod to rotate, and further drive one of the first gears to rotate, and also make the other first gear mesh and rotate. When the first gear rotates, the rotating rod and the crushing roller will rotate. Then, the 3D printing waste is put between a pair of second-layer shielding plates, which will cause the second-layer shielding plates to deform during extrusion, and then the 3D printing waste will enter between the pair of first-layer shielding plates, and further enter the pair of crushing rollers for processing. During the processing, the 3D printing waste will splash and generate dust. The splashed waste and dust will be shielded by the second-layer shielding plates, which prevents the waste from splashing out of the chassis and prevents dust from floating out of the chassis.

[0016] S2. The rotation of the rotating rod will cause the third pulley to rotate, which will then drive the fourth pulley to rotate through the belt, which will cause the support rod to drive the second gear to mesh and rotate, which will further cause a pair of second gears to mesh and rotate, and the second gear will drive the connecting rod to rotate, which will also cause the roller to rotate. The unevenly crushed 3D printing waste will be further crushed between the pair of rollers, and the crushed 3D printing waste will fall onto the first screen plate. At the same time, the vibration of the first layer of shielding plate will cause the connecting support plate to vibrate, which will then cause the first screen plate, the first U-shaped plate, the second screen plate, the second U-shaped plate and the third screen plate to vibrate. The vibration of the first screen plate will cause the crushed 3D printing waste to be sieved, and the 3D printing waste that meets and is smaller than the aperture of the first screen hole will fall onto the second screen plate, and the 3D printing waste that is larger than the aperture of the first screen hole will slide through the first U-shaped plate To the first inclined hole, slide into the first U-shaped discharge plate again, and fall from the first lower hopper for recycling. The 3D printing waste that falls on the second screen plate will be sieved during the vibration. The 3D printing waste that meets or is smaller than the second screen hole aperture will fall onto the third screen plate. The 3D printing waste that is larger than the second screen hole aperture will slide through the second U-shaped plate into the second inclined hole, further slide into the second protective cover, and further fall through the second lower hopper for recycling. The 3D printing waste that falls on the third screen plate will be sieved during the vibration. The 3D printing waste that meets or is smaller than the third screen hole aperture will fall into the collection box. The 3D printing waste that is larger than the third screen hole aperture will slide through the third screen plate into the third inclined hole, further fall into the second U-shaped discharge plate, and further fall through the third lower hopper for recycling.

[0017] S3. During use, the dust raised during screening will be blocked by the crushing roller and the first layer of shielding plate, and the dust will overflow through the first dust collecting tube and the second dust collecting tube, and then gather at the outer end of the first dust collecting tube to be collected;

[0018] S4. During use, natural wind or blowing air will enter the chassis through the third dust collecting tube, further cooling the crushing roller and the grinding roller, accelerating the dust raising, and assisting the integrated components to quickly collect the dust. Compared with the prior art, the beneficial effect of the present invention is that the present invention not only blocks the splashing of waste materials, but also blocks the dust by arranging a circular plate, a first layer of shielding plate and a second layer of shielding plate, and also facilitates the rapid unloading of waste materials, further avoiding harm to the operator.

[0019] Through the coordinated arrangement of the multi-layer screening component, the first recycling component, the second recycling component, the third recycling component and the second crushing component, the present invention not only processes the 3D printing waste, but also performs graded recycling of the processed 3D printing waste, further facilitating the processing of the recycled 3D printing waste and avoiding the subsequent grading work.

[0020] By arranging the integrated components, the present invention can collect dust, further preventing the dust from polluting the surrounding environment and causing damage to the operator's body.

[0021] By providing the third dust collecting barrel, cracking and damage of the roller due to overheating fatigue during long-term operation can be avoided.

[0022] To sum up the above structure, the present invention not only blocks the splashing of waste materials, but also blocks dust, and also facilitates the rapid unloading of waste materials, further avoiding harm to operators. At the same time, by collecting dust, it further avoids dust pollution to the surrounding environment and harm to operators. Not only 3D printing waste is processed, but also the processed 3D printing waste is graded and recycled, which further facilitates the processing of the recycled 3D printing waste and avoids later grading work. At the same time, it avoids the occurrence of cracking and damage of the roller due to overheating fatigue during long-term operation. BRIEF DESCRIPTION OF THE DRAWINGS

The vibration of the first sieve plate 215 will cause the crushed 3D printing waste to be sieved, and the 3D printing waste that meets or is smaller than the first sieve hole diameter will fall onto the second sieve plate 217, and the 3D printing waste that is larger than the first sieve hole diameter will slide through the first U-shaped plate 216 to the first inclined hole 2 21, slides into the first U-shaped discharge plate 223 again, and falls from the first lower hopper 225 for recovery. The 3D printing waste falling on the second sieve plate 217 will be sieved in the vibration, and the 3D printing waste that meets or is smaller than the second sieve hole diameter will fall onto the third sieve plate 219. The 3D printing waste that is larger than the second sieve hole diameter will slide through the second U-shaped plate 218 into the second inclined hole 231, and further slide into the second protective cover 233, and further The 3D printing waste falling on the third sieve plate 219 will be sieved in the vibration, and the 3D printing waste meeting or smaller than the third sieve hole diameter will fall into the collection box 25, and the 3D printing waste larger than the third sieve hole diameter will slide through the third sieve plate 219 into the third inclined hole 241, and further fall into the second U-shaped discharge plate 243, and further fall through the third lower hopper 246 for recycling;
