Compacting material bin applied to plastic film cleaning and recycling production line

Abstract

The invention discloses a compacting material bin applied to a plastic film cleaning and recycling production line. The compacting material bin comprises a material storage hopper and a feeding hopper. An annular vertical partition plate is arranged in the material storage hopper. By means of the annular vertical partition plate, the interior of the material storage hopper is partitioned into an inner cavity and an outer annular cavity. A discharging opening of the inner cavity is connected with a reversible type conveyor. A vertical type spiral conveyor is arranged in the inner cavity. Multiple annular horizontal partition plates are arranged in the outer annular cavity of the material storage hopper at intervals from top to bottom. By means of the annular horizontal partition plates, the outer annular cavity is partitioned into multiple sub-cavities. Multiple air inlets are formed in the positions, corresponding to the sub-cavities, of the annular vertical partition plate. Air outlets are formed in the positions, corresponding to the sub-cavities, of the outer wall of the material storage hopper. Each air outlet is provided with an air volume adjusting valve. All the air outlets are connected with an inlet of an air outlet pipe at the same time. The air outlet pipe is connected with a feeding pipe through an air drier, a heater and a pneumatic conveyor in sequence. The feeding pipe extends into the inner cavity through the upper portion of the material storage hopper. The feeding hopper is connected with the feeding pipe. The compacting material bin applied to the plastic film cleaning and recycling production line has the function that materials can be dried and compacted.

Description

technical field [0001] The invention relates to the technical field of recycling and processing of polymeric materials, in particular to a compacting bin in a plastic film cleaning and recycling production line. Background technique [0002] The silo is the main equipment of the plastic film cleaning and recycling production line, mainly used for storage and unloading. The currently used silos have the following disadvantages: (1) The structure is simple and the function is single, and the materials in the silo cannot be dried, which affects the product quality; (2) The bulk density of the film materials stored in the silo is very low, resulting in The material storage volume in the unit space of the silo is small, resulting in a small amount of material output from the silo per unit time, which in turn affects the working efficiency of the plastic film recycling production line. Contents of the invention [0003] The object of the present invention is to provide a compac...
