Description

Technical Field

[0001] The utility model relates to the technical field of rolling screens, in particular to a rolling screen for treating construction waste. Background Art

[0002] Construction waste refers to the collective term for slag, waste concrete, waste bricks and stones, and other waste generated during demolition, construction, renovation, and repair activities in the construction industry. By source, construction waste can be divided into construction slag, renovation waste, demolition waste, and construction mud. By composition, construction waste can be divided into slag, concrete blocks, crushed stone, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metal, and waste bamboo and wood.

[0003] At present, in order to avoid polluting the environment, construction waste is generally recycled. Due to the different types and sizes of garbage, different rolling screens are needed to classify them. The existing vertical rolling screen will generate dust during screening because the drum screen is directly exposed to the outside world, which pollutes the environment and causes certain harm to the workers.

[0004] Therefore, in response to the above problems, we propose a rolling screen for construction waste treatment. Utility Model Content

[0005] The purpose of the utility model is to provide a rolling screen for treating construction waste, so as to solve the problems raised by the above-mentioned background technology.

Two scrapers 9 distributed up and down are fixedly installed on the outer wall of the rolling screen drum 3, and the end of the scraper 9 away from the rolling screen drum 3 is in contact with the dustproof shell 2.

[0021] During specific use, the rolling screen drum 3 rotates and drives the scraper 9 to scrape the inner wall of the dustproof shell 2 to remove dust contaminated on the inner wall of the dustproof shell 2.

Because the rubber sheet 504 conflicts with the drive ring 4, the drive ring 4 and the rolling screen drum 3 can be driven to rotate by the rubber sheet 504. The larger construction waste is sent out from both ends of the rolling screen drum 3, while the smaller ones pass through the rolling screen drum 3 and the leakage hole 10 to screen the construction waste inside the rolling screen drum 3. The dust generated during the rotation of the rolling screen drum 3 is blocked by the dustproof shell 2 and the dustproof plate 6, reducing the environmental pollution problem caused by dust, and also improving the safety of the staff. During the rotation of the rolling screen drum 3, the scraper 9 will be driven to scratch the inner wall of the dustproof shell 2 to remove the dust contaminated on the inner wall of the dustproof shell 2.
