Description

Technical Field

[0001] The invention belongs to the technical field of material separation and relates to a device for separating cement, steel bars and stones from construction waste of water conservancy projects. Background Art

[0002] In the process of water conservancy project construction, the main material is reinforced concrete, which is one of the more common materials in modern buildings. After the demolition of such buildings, a lot of construction waste containing reinforced concrete will be generated. These construction wastes need to be sorted and recycled, so a construction waste sorting machine is needed. At present, the method of sorting construction waste mainly adopts a combination of manual sorting and mechanical sorting. The construction waste is preliminarily screened on the construction site manually, and the steel bars that can be taken away directly from the construction waste are picked up. The remaining construction waste is transported to the crusher by mechanical equipment for crushing, and the crushed stones or powders are sent to the filter and iron removal device for processing. However, the stones of reinforced concrete are wrapped with steel bars, and such steel bars can be directly recycled. In the prior art, it is necessary to crush them and the stones into powder together, and then use a magnetic absorption device to absorb the iron-containing powder to complete the recycling of the steel bars. The operation steps are relatively cumbersome, and it is easy to cause insufficient removal of iron-containing substances after the stones and steel bars are crushed into powder, so that the iron-containing substance content in the recycled stone is high, which affects the quality of building material recycling. In view of the existing situation, a device for separating cement, steel bars and stones from construction waste of water conservancy projects is proposed.

[0003] The application number is 202311749551.3, which discloses a construction waste sorting machine, including a frame and a crusher, a vibrating material guide device is rotatably installed on the side wall of the frame, a conveyor is provided under the frame, the crusher is located on one side of the frame, the feed port of the crusher is docked with the material guide device, and a separation device for separating steel bars and cement is placed on the side of the crusher away from the frame, and the separation device is aligned with the discharge port of the crusher. The present invention uses a crocodile crusher to crush stones, and sets a separation device at the outlet of the crusher, so that the crushed stones fall below the separation device after passing through the separation device, and the steel bars follow the iron-absorbing bars on the separation device to move into the iron collection box, and the separation of stones and steel bars can be automatically completed after the reinforced concrete is crushed, and the steel bars can be automatically collected.

[0004] However, there are some shortcomings. The device crushes the stones by using a crocodile crusher, and a separation device is arranged at the outlet of the crusher, so that the crushed stones fall below the separation device after passing through the separation device, and the steel bars move to the iron collecting box following the iron suction bar on the separation device. After the reinforced concrete is crushed, the separation of stones and steel bars can be automatically completed, and the steel bars can be automatically collected. However, the device does not screen the selected objects in the construction waste in detail during the sorting process, and it is more troublesome to put the construction waste into the sorting structure, which requires manual input.
