Abstract

The invention discloses a thermal cleaning and filtering device capable of effectively separating a label from an alkali solution for thermally cleaning waste plastic. A foaming belt conveyor is arranged in a water tank; a charging hopper of the foaming belt conveyor is positioned inside the water tank; the discharging end of the foaming belt conveyor is positioned outside the water tank; a material collecting hopper is arranged below the discharging end; a detachable filter screen is arranged on the right side of the foaming belt conveyor; through holes are uniformly formed in the filter screen; a sewage outlet and a water pumping port are formed in the right side of the filter screen; a high-level switch and a low-level switch are arranged on the side surface of the water tank.

Description

technical field [0001] The invention relates to a filtering device, in particular to a device for filtering alkali solution after thermal cleaning of waste plastics in the waste plastics cleaning and recycling industry. Background technique [0002] Recycled waste plastics mainly include: film packaging bags, beverage bottles, pipes, etc. Among them, the film packaging bags and beverage bottles usually contain labels pasted with adhesives. After crushing, some labels are broken into pieces and separated from the recycled materials. It is separated from the recycled materials through the subsequent separation device, and some labels are still adhered to the recycled materials. The purpose of hot cleaning is to soften and dissolve the adhesive for pasting the labels, so that the labels are separated from the recycled materials. In order to prevent the adhesive from falling off To re-adhere recycled materials, alkali is usually added to the hot cleaning solution. In order to ac...
