Abstract

The invention relates to a dry centrifugal separation device for waste sludge from a paper mill, and belongs to the technical field of material separation devices. The dry centrifugal separation device for the waste sludge from the paper mill comprises a supporting base, wherein a screening tube is fixedly arranged on the supporting base, and the two ends of the upper part of the screening tube are respectively provided with a discharge port and a feed port; and a centrifugal rotor with blades on the surface is arranged in the inner cavity of the screening tube, and one end of the centrifugalrotor is in transmission connection with a motor fixedly arranged on the supporting base. Through the dry centrifugal separation device, components with higher density in the waste sludge from the paper mill are separated from components with lower density to achieve the utilization of various components in the waste sludge from the paper mill, and the environmental pollution cannot be generated.

Description

technical field [0001] The invention belongs to the technical field of material separation devices, and in particular relates to a dry centrifugal separation device for papermaking waste residue. Background technique [0002] Due to the low cost and the ability to alleviate the shortage of raw materials for papermaking, papermaking from waste paper occupies a relatively large proportion in the papermaking industry and shows a growing trend. However, waste paper and papermaking also produce a large amount of waste residue, the main components are residual pulp and waste plastics, among which waste plastics are not easy to degrade, so how to properly deal with papermaking waste residue has become a thorny and imminent problem. At present, there are two main ways to deal with papermaking waste: landfill and recycling. Landfill itself does not solve the environmental problems caused by papermaking waste residue, but only avoids the pollution problem. The premise of recycling p...
