Description

Technical Field

[0001] This utility model relates to the field of construction engineering material sorting technology, and in particular to an automatic sorting device for construction engineering materials. Background Technology

[0002] Material sorting in construction projects plays a vital role in construction waste management. With rapid urbanization, construction projects generate a large amount of construction waste. Proper material sorting helps reduce environmental pollution and achieve resource recycling. Automated material sorting devices are used in the proper sorting and processing of construction waste.

[0003] An automatic sorting device for construction materials separates useful materials such as concrete blocks, bricks, and steel bars from construction waste through the rotation of a drum and the action of screening. The electric motor drives the drum to rotate, and the construction waste enters the drum under the action of gravity. Materials of different sizes and densities are separated into layers due to centrifugal force, with larger particles pushed to the outside and smaller particles left on the inside.

[0004] In existing technologies, although construction waste can be sorted and centrifuged by rotating a drum driven by an electric motor, the outside of the drum is easily blocked if it is not cleaned in time, which affects the sorting efficiency and makes it inconvenient to use. Therefore, an automatic sorting device for construction materials is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic sorting device for construction materials, which aims to improve the problem in the prior art where, during the centrifugal screening and sorting process driven by an electric motor, failure to clean the outside of the drum in a timely manner can easily cause the drum to become clogged, thus affecting the screening and sorting efficiency.

The motor 8 provides driving power. The rotating power of the drive gear 7 drives the meshing external gear ring 6 to rotate, thereby causing the sorting screen cylinder 5, which is fixedly connected to the external gear ring 6, to rotate synchronously. Under the action of centrifugal force, the sorting screen cylinder 5, which has three sections of automatic sorting screen holes with different specifications for construction materials, can automatically screen and sort construction waste materials. The top of the inner wall of the main body 1 is provided with a cleaning component 9. The top of the two partitions 2 are provided with installation clearance holes with a size larger than the width of the cleaning component 9. The cleaning component 9 includes a mounting frame 91.

The cleaning brush 92, which is fixedly installed on the top of the inner wall of the main body 1 through the mounting frame 91, facilitates the cleaning of the outer surface of the rotating sorting screen cylinder 5, which can effectively clean and avoid clogging of the automatic sorting screen holes of construction materials on the sorting screen cylinder 5, thereby improving the automatic screening and sorting efficiency.

[0032] Reference Figure 1 , Figure 3 and Figure 4A fixed frame 10 is fixedly connected to the left side of the main body 1 of the device. A feeding hopper 11 for feeding construction waste materials is fixedly connected inside the fixed frame 10. The right output end of the feeding hopper 11 extends into the feed hole of the sorting screen cylinder 5. A feeding dust suction hood 12 for feeding dust control is fixedly connected to the upper left edge of the fixed frame 10. A discharging dust suction hood 13 for discharging dust control is fixedly connected to the upper right edge of the main body 1. A screening dust suction hood 14 for screening dust control is set at the top inside the main body 1.

This ensures the pollution prevention and environmental protection effect of the automatic sorting and processing of construction materials, thereby improving the environmental protection and pollution reduction efficiency of the device.

[0033] Working Principle: During operation, materials to be sorted are fed into the feeding hopper 11. The starting motor 8 provides power to drive the gear 7, which in turn drives the meshing external gear ring 6 to rotate. This causes the sorting screen cylinder 5, fixedly connected to the external gear ring 6, to rotate synchronously. The sorting screen cylinder 5, with three sections of different-sized automatic sorting holes for construction materials, automatically sorts and discharges construction waste materials under centrifugal force. Materials sorted by different sizes under centrifugal force are discharged through the corresponding sorting hopper 4. During the sorting operation, the dust extraction fan 163 is simultaneously activated. Driven by the dust extraction fan 163, the dust is drawn from the left side of the purification box 161 and... A first dust suction duct 165 is fixedly connected to the top of the feeding dust hood 12. A second dust suction duct 166 is fixedly connected to the right rear edge of the purification box 161 and the top of the discharging dust hood 13. A third dust suction duct 167 is fixedly connected to the back of the purification box 161 and the top of the screening dust hood 14. This system can centrally collect and use the dust generated during the feeding of materials into the feeding hopper 11, the screening and sorting of materials into the sorting sieve cylinder 5, and the discharging process. The dust is filtered through the purification box 161 with the filter plate 162 to achieve environmental protection and emission reduction. This system can ensure the pollution prevention and environmental protection effect of the automatic sorting and processing of construction materials, thereby improving the environmental protection and pollution reduction efficiency of the device.
