Waste plastic drier

Abstract

The invention discloses a waste plastic drier, which comprises an external steel-frame structure and a drying component, wherein the drying component comprises a material conveying device, a blade stirring mechanism, a screening mechanism, a drying air distribution system and a deslagging mechanism; the blade stirring mechanism comprises at least one group of stirring components which is fixed on the steel-frame structure of the drier; each group of stirring components comprises a stirring spindle and at least one pair of stirrers which is fixed on the stirring spindle; each pair of stirrers comprises two stirring shafts and two blades, which are in opposite direction; the blades are arranged at the tail ends of the stirring shafts; the front end of each stirrer is fixed on the stirring spindle; and each group of stirring components is connected with a driving device. The waste plastic drier has the advantages that before entering an oil smelter, a material such as waste plastic is simultaneously stirred, dried, screened and deslagged, the quality of the material such as the waste plastic which does not enter the oil smelter is fully improved, and the quality of an oil product is improved.

Description

technical field [0001] The invention relates to a dryer, in particular to a dryer for waste plastics. Background technique [0002] In the domestic waste plastics refining and recycling project, the drying of waste plastics is very important. If the waste plastics enter the refining furnace directly, it needs to consume a lot of energy to dry, melt, crack, regenerate, and synthesize the wet plastics. A large amount of carbon residue, waste plastic refining efficiency is very low, and the economic benefit is low. There is no drying equipment in front of the existing waste plastic oil refining equipment, and it is generally dried naturally or directly into the oil refining furnace. Natural drying requires manual opening and dismantling of the plastic bag, and frequent flipping. "Depending on the weather", the weather is good and sunny, the plastic dries faster, and the weather is cold and sunny, the plastic dries slowly. It takes many days to dry and takes up a lot of space. ...

AI Technical Summary

Problems solved by technology

Natural drying requires manual opening and dismantling of the plastic bag, and frequent flipping. "Depending on the weather", the weather is good and sunny, the plastic dries faster, and the weather is cold and sunny, the plastic dries slowly. It takes many days to dry and takes up a lot of space. Large area; since small workshop-style oil refining has been cancelled, and large-scale waste plastic refineries have no pre-treatment equipment, large-scale, mechanized, and continuous production cannot be formed

And there is no quick-drying dryer, nor is the internal paddle stirring mechanism

At present, it is only turned over and stirred manually in the drying yard.
