High performance dehydrating drier

Abstract

This invention discloses a high efficient dewater drier of low energy cost and capable of on-line drying instantly including: a frame, a cylinder shell, an outfall, a main shaft and a drive device, in which a feed inlet and a discharge port are set on both ends of the top of the shell along the tangent direction of the cylinder, a filter net with a polygonal cross section is fixed in the shell, several blade bases are set on the main shaft and each base includes three blades uniformly distributed along the cylindrical direction, and blades on the odd number bases are distributed one by one slanting 0.4-0.9deg to a same direction and those on the even number bases are distributed slanting 0.4-0.9deg one by one to a same direction, the included angle of the top surface of each blade and axis of the main shaft is 6-15deg, when every blade is at the highest position, the included angle of its outside surface and the vertical surface passing through the sideline is 6-15deg. This equipment can be used in plastic recovery field.

Description

technical field [0001] The invention relates to a high-efficiency dehydration dryer capable of dehydrating and drying cleaned waste plastic films, sheets and other materials. Background technique [0002] In the recycling and granulation industry of waste plastics, such as plastic films and plastic sheets, the commonly used process is: first crush the raw materials, then clean them, then dehydrate and dry them, and finally granulate them with an extruder. Most of the current dehydration and drying processes are to use mechanical centrifugal dehydration to heat and dry the crushed and cleaned materials, that is, dehydration and drying need to be completed in two steps. Such a production process not only increases equipment investment costs and consumes a lot of energy, but also Low output is also an unavoidable and difficult problem to solve. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-efficiency dehyd...
