[0026] This disclosure aims to address the problem that existing 3D printing processes typically generate a large amount of construction waste. While this waste is usually collected and disposed of centrally, this method fails to provide effective and systematic recycling, particularly in terms of rapid crushing and screening. Therefore, this disclosure proposes a high-efficiency 3D printing construction waste processing device. By incorporating a crushing and screening device, and using a motor to drive two rotating shafts in opposite directions, the device achieves a crushing effect, breaking down large pieces of construction waste. The waste is then progressively screened by a bottom screening component, enabling the classified recycling of the construction waste.
[0027] like Figures 1 to 6 As shown, a high-efficiency 3D printing construction waste processing device includes a support frame 1 and a control unit 2. The control unit 2 is installed on the support frame 1. The device also includes a crushing device 3 and a screening device 4. The crushing device 3 is installed on the support frame 1 and is used to crush the solidified construction waste generated during printing. The screening device 4 is installed at the bottom of the crushing device 3 and is used to screen and classify the crushed construction waste.
[0028] By setting up a crushing device 3 and a screening device 4, and driving two rotating shafts to rotate in opposite directions by a motor, the crushing effect of the crushing component 35 is achieved, which crushes large pieces of construction waste. The construction waste is then screened step by step by the screening component at the bottom, thereby achieving the classification and recycling of construction waste.
[0029] like Figures 1 to 4As shown, the crushing device 3 includes a feed inlet 31, a screening frame 32, a crushing motor 33, a rotating shaft, a crushing assembly 35, and a discharge outlet 36. The feed inlet 31 is mounted on the support frame 1 and is used to guide construction waste into the screening frame 32. The screening frame 32 is installed at the bottom of the feed inlet 31 and is used to support the crushing assembly 35. The crushing motor 33 is installed on one side of the screening frame 32 and is used to drive the rotating shaft to rotate. A first rotating shaft 34 is installed at the output end of the crushing motor 33 and is used to rotate and drive the crushing assembly 35 to rotate. A first gear 38 is installed at the other end of the rotating shaft 34. The rotation of the first gear 38 drives the rotation of the second gear 39. The first gear 38 is meshed with the second gear 39 on one side. The rotation of the second gear 39 drives the rotation of the second rotating shaft 37. The second rotating shaft 37 is installed at the center of the second gear 39. The other end of the second rotating shaft 37 is installed on the screening frame 32. The rotation of the second rotating shaft 37 drives the crushing assembly 35 to rotate. Crushing assemblies 35 are installed on both the first rotating shaft 34 and the second rotating shaft 37. The bottom of the screening frame 32 is provided with a discharge port 36, which is used to guide the crushed construction waste into the screening device 4.
[0030] During operation, construction waste enters the screening frame 32 through the feed inlet 31. At this time, the crushing motor 33 is started by the control unit 2. The crushing motor 33 drives the rotating shaft to rotate. The rotating shaft drives the crushing component 35 to rotate and at the same time drives the first gear 38 to rotate. The rotation of the first gear 38 drives the meshing second gear 39 to rotate. The rotation of the second gear 39 drives the second rotating shaft 37 to rotate. The rotating second rotating shaft 37 drives the crushing component 35 to rotate. The crushing effect is achieved by the first rotating shaft 34 driving the crushing component 35 and the second rotating shaft 37 driving the crushing component 35 in opposite directions.
[0031] The motor drives two rotating shafts to rotate in opposite directions, thereby achieving the crushing effect of the crushing component 35, breaking down large pieces of construction waste, and enabling the construction waste to be better reused.
[0032] like Figure 3As shown, the crushing assembly 35 includes limiting strips 351, rotating disks 352, and crushing blocks 353. The limiting strips 351 are arrayed and installed on both sides inside the screening frame 32, and are used to guide the construction waste. Rotating disks 352 are arrayed on both the first rotating shaft 34 and the second rotating shaft 37, and are used to drive the crushing blocks 353 to rotate. The rotating disks 352 on the first rotating shaft 34 and the rotating disks 352 on the second rotating shaft 37 are arranged alternately, and the crushing blocks 353 are arranged in a ring array on the rotating disks 352, and are used to crush the construction waste. The construction waste is guided onto the crushing blocks 353 by the limiting strips 351, and the rotation of the rotating disks 352 drives the crushing blocks 353 to rotate, thereby achieving the crushing effect.
[0033] like Figure 5 As shown, a primary screen 361 is installed inside the discharge port 36. The primary screen 361 is set at the bottom of the discharge port 36 to continue crushing the construction waste that has not been completely crushed in the crushing assembly 35.
[0034] like Figure 6 As shown, the screening device 4 includes a fixed rod 41, a first screening screen 42, a second screening screen 43, a third screening screen 44, an adjusting rod 45, a hydraulic cylinder 46, and a controllable baffle 47. The fixed rod 41 is symmetrically installed on the support frame 1 and is used to fix the first screening screen 42, the second screening screen 43, and the third screening screen 44. The first screening screen 42, the second screening screen 43, and the third screening screen 44 are hinged to the support frame 1. The first screening screen 42, the second screening screen 43, and the third screening screen 44 are used to screen the crushed construction waste. Each of the No. 1 screening screen 42, No. 2 screening screen 43, and No. 3 screening screen 44 is equipped with an adjusting rod 45 at one end. The adjusting rod 45 is used to adjust the tilt angle of the No. 1 screening screen 42, No. 2 screening screen 43, and No. 3 screening screen 44. A hydraulic cylinder 46 is installed at one end of the adjusting rod 45. The hydraulic cylinder 46 is used to extend and retract the adjusting rod 45. The hydraulic cylinder 46 is installed on the support frame 1. A controllable baffle 47 is installed on one side of the No. 1 screening screen 42, No. 2 screening screen 43, and No. 3 screening screen 44 along the adjusting rod 45. The controllable baffle 47 is used to open to allow construction waste to be poured out.
[0035] During operation, the rotation of the crushing motor 33 causes vibration in the No. 1 screening screen 42, No. 2 screening screen 43, and No. 3 screening screen 44. The vibration of the No. 1 screening screen 42, No. 2 screening screen 43, and No. 3 screening screen 44 accelerates the filtration of construction waste. After the construction waste is filtered, the control unit 2 controls the hydraulic cylinder 46 to extend and the adjusting rod 45 to move upward. The moving adjusting rod 45 causes the No. 1 screening screen 42, No. 2 screening screen 43, and No. 3 screening screen 44 to tilt, and in conjunction with the sequential opening of the controllable baffle 47, the sifted construction waste is collected.
[0036] like Figure 6 As shown, the mesh counts of the No. 1 screening screen 42, No. 2 screening screen 43, and No. 3 screening screen 44 decrease sequentially from top to bottom. This arrangement allows for better screening of construction waste.
[0037] The overall working process is as follows: Construction waste enters the screening frame 32 through the feed inlet 31. At this time, the crushing motor 33 is started by the control unit 2. The crushing motor 33 drives the rotating shaft to rotate. The rotating shaft drives the crushing assembly 35 to rotate and simultaneously drives the first gear 38 to rotate. The rotation of the first gear 38 drives the meshing second gear 39 to rotate. The rotation of the second gear 39 drives the second rotating shaft 37 to rotate. The rotating second rotating shaft 37 drives the crushing assembly 35 to rotate. The first rotating shaft 34 drives the crushing assembly 35 in opposite directions, and the second rotating shaft 37 drives the crushing assembly 35 in opposite directions. The rotation achieves the crushing effect; due to the rotation of the crushing motor 33, the first screening screen 42, the second screening screen 43 and the third screening screen 44 all vibrate. The vibration of the first screening screen 42, the second screening screen 43 and the third screening screen 44 will accelerate the filtration of construction waste. After the construction waste is filtered, the control unit 2 controls the hydraulic cylinder 46 to extend and the adjusting rod 45 to move upward. The moving adjusting rod 45 drives the first screening screen 42, the second screening screen 43 and the third screening screen 44 to tilt, and in conjunction with the sequential opening of the controllable baffle 47, the collected construction waste after screening is completed.
