Rinsing device used in plastic film cleaning and recycling production line

Abstract

The invention discloses a rinsing device used in a plastic film cleaning and recycling production line. The rinsing device comprises a shell, a roller which is driven by a speed reducing motor to rotate is movably supported between a front side plate and a back side plate of the shell through a pair of bearings and bearing pedestals, and a plurality of bolts are spirally arranged on the outer circumferential wall of the roller in the axial direction at intervals; a feeding inlet is formed in the top of the shell, a discharging outlet is formed in the back end of the shell, a water outlet is formed in the bottom of the shell, a discharging control valve is arranged at the discharging outlet of shell, and the water outlet of the shell is covered with a perforated plate; an impurity storing hopper of which a top feeding inlet communicates with the water outlet of the shell in a butt-joint mode is arranged under the shell, an unloading control valve is arranged at a bottom unloading outlet of the impurity storing hopper, and a cleaning agent adding mechanism capable of adding a cleaning agent into the shell is arranged on the shell. The rinsing device has the advantages of being good in cleaning effect, high in cleaning efficiency and small in occupation area.

Description

technical field [0001] The invention relates to the technical field of recycling and processing of polymeric materials, in particular to a rinsing device in a plastic film cleaning and recycling production line. Background technique [0002] The rinsing device is an important equipment in the plastic film cleaning and recycling production line. It is mainly used to clean the pre-crushed plastic films (such as PE, PP, PVC, PET). The currently used rinsing device is mainly composed of several connected rinsing tanks, which mainly achieve the purpose of cleaning by the material moving along the tank body in the water flow of the rinsing tank. The currently used rinsing device has the following shortcomings: (1) Before the material enters the rinsing tank, the material needs to be separated into floating material and sedimentary material, and then the floating material and the sedimentary material are cleaned respectively, which is cumbersome to operate and has low cleaning effi...

AI Technical Summary

Problems solved by technology

The currently used rinsing device has the following disadvantages: (1) Before the material enters the rinsing tank, the material needs to be separated into floating material and sedimentation material, and then the floating material and sedimentation material are cleaned separately. The operation is cumbersome and the cleaning efficiency is low. It affects the working efficiency of the production line; (2) Multiple rinsing tanks are required to clean the materials, resulting in a large area occupied by the rinsing device and high energy consumption of water and electricity, which greatly increases the cost of the enterprise
