Embodiment Construction

[0017] Further describe the present invention with embodiment below in conjunction with accompanying drawing, the scope of the present invention is not limited by these embodiments. The scope of the present invention is set forth in the claims.

[0018] Such as figure 1 In the shown flotation separation device, the aspect ratio of the separation box 12 is 4. The separation liquid 4 is housed in the separation box 12 . A feed inlet 2 is arranged above one end of the separation box 12 , and a hopper 1 is connected above the feed inlet 2 . A liquid inlet 10 for circulating the separation liquid is provided next to the feed inlet 2 . A stirring wheel 3 is arranged below the feeding port 2 and on the liquid surface of the separating liquid. The central axis of the stirring wheel 3 is parallel to the liquid surface of the separating liquid. The rotational speed of the stirring wheel 3 is 300 rpm. The part of the paddle of the stirring wheel 3 that is not in the liquid surface ...

Abstract

A floatation separator for waste plastic is composed of separating tank containing separating liquid and stirring unit. After stirred, the waste plastics is immersed in the separating liquid. By floatation, the light material is discharged from the top discharge outlet and the heavy material is discharged from the bottom discharge outlet. Its advantages are high separation efficiency and productivity, and wide application range.

Description

technical field [0001] The invention relates to a separation device for waste plastics, and more particularly, relates to a device for separating waste plastics by means of flotation. Background technique [0002] There are many ways to separate the mixture, among which the flotation separation method is to immerse the mixed material in the separation liquid to separate the light and heavy materials according to the density of the mixed material. A device for separating mixed materials by flotation, especially a device for flotation and separation of waste plastics, has not been reported in the literature. At present, the technology of waste plastic recycling and reuse can not only reduce "white pollution" but also save energy, so it has been paid more and more attention by people. However, the classification of waste plastics is a prerequisite for recycling technology, and it is also a difficult problem for recycling technology. Usually, people classify waste plastics thr...
