Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment technology, specifically to a construction waste treatment device. Background Technology

[0002] Resource utilization of construction waste (such as concrete blocks, brick and tile fragments, and waste steel bars) is an important part of the green development of the construction industry.

[0003] Traditional equipment crushes waste materials using only a single crushing roller, lacking a targeted screening structure. This results in the crushed aggregate containing particles of different sizes, requiring secondary manual screening before it can be used as recycled material, which is inefficient. Furthermore, the waste contains metallic impurities such as steel bars and iron wires mixed with non-metallic waste. Existing equipment often relies on manual sorting or subsequent magnetic separation equipment, which not only increases labor intensity but also makes it easy for metallic impurities to enter subsequent processes due to incomplete separation, damaging the equipment or affecting the quality of recycled aggregate.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1-4 As shown, this utility model has the following four specific embodiments.

A servo motor c23 is fixedly connected to the rear side of the processing box 1. The output shaft of the servo motor c23 extends into the processing box 1 and is fixedly connected to the crushing rollers 9. The front ends of the two crushing rollers 9 extend out of the processing box 1 and are fixedly connected to gears a19 and b20, with gears a19 and b20 meshing. The device is characterized by further comprising:

[0035] A connecting plate 4 is fixed to the inner left side of the processing box 1. Several spring rods a11 are evenly fixed to the upper side of the connecting plate 4. A screening plate 12 is fixed to the telescopic end of the spring rods a11. A discharge port a14 is opened on the right side of the processing box 1. Several spring rods b13 are evenly fixed to the lower side of the discharge port a14. The screening plate 12 is fixed to the telescopic end of the spring rods b13. The screening plate 12 is slidably connected inside the processing box 1.

[0036] Screening mechanism, used to drive the screen plate 12 to vibrate;

[0037] The active roller 161 and the driven roller 162 are rotatably connected inside the processing box 1. The active roller 161 is connected to the driven roller 162 via a magnetic conveyor belt 163. A waste discharge port b is opened on the right side of the processing box 1. A guide plate b17 is fixedly connected to the lower side of the waste discharge port b. A discharge pipe 18 is fixedly connected to the lower side of the processing box 1. A scraper 24 is fixedly connected inside the processing box 1. The upper side of the scraper 24 is in contact with the lower side of the magnetic conveyor belt 163.

[0038] The sorting mechanism is used to drive the drive roller 161 and the driven roller 162 to rotate.

[0039] In this embodiment, as Figures 1-2 ,as well as Figures 3-4 As shown, construction waste is poured into the processing box 1 through an external transmission device. The servo motor c23 drives the right crushing roller 9 to rotate, the right crushing roller 9 drives the gear b20 to rotate, the gear b20 drives the gear a19 and the left crushing roller 9 to rotate, and the two crushing rollers 9 move relative to each other, thereby crushing the construction waste.

[0040] The crushed construction waste falls onto the upper side of the screening plate 12. The screening mechanism drives the screening plate 12 to vibrate. The vibration of the screening plate 12 screens the construction waste of the required particle size. The construction waste that does not meet the particle size is discharged through the discharge port a14 so that it can be crushed again later.

[0041] After screening, the construction waste falls onto the upper side of the magnetic conveyor belt 163. The sorting mechanism drives the magnetic conveyor belt 163 to rotate. Construction waste that meets the particle size requirements is discharged from the processing box 1 through the guide plate b17 and the discharge port b15. The magnetic conveyor belt 163 adsorbs the iron in the construction waste, thus sorting the construction waste. The magnetic conveyor belt 163 drives the adsorbed iron to rotate. The scraper 24 scrapes off the iron on the magnetic conveyor belt 163. The scraped iron is discharged from the processing box 1 through the discharge pipe 18.

The cam 212 is attached to the lower side of the screening plate 12. The output shaft of the servo motor b211 extends into the processing box 1 and is fixed to the cam 212.

[0052] In this embodiment, as Figure 2 and Figure 4 As shown, the servo motor b211 drives the cam 212 to rotate, and the cam 212 pushes the screening plate 12 to move up and down.

The splash guard 2 blocks the debris splashed by the crushing roller 9. Water is injected into the diversion pipe 71 through the water inlet pipe 5. The diversion pipe 71 injects water into the misting nozzle 74 through the connecting pipe a72 and the connecting pipe b73. During the treatment of construction waste, the dust is reduced by spraying water mist.

[0062] Servo motor b211 drives cam 212 to rotate, cam 212 pushes screen plate 12 to move up and down, spring rod a11 and spring rod b13 limit the up and down moving screen plate 12 and amplify the vibration, and the filter holes on screen plate 12 screen the crushed construction waste.
