HDPE bottle washing recycling line

1.The production line is designed according to three main process processes, including the crushing and cleaning module (including the internal water circulation, filtration and reuse system of the production line)

a) Description of the module of the crushing and cleaning process section: The crushing and cleaning module includes secondary crushing and secondary rinsing and air flow sorting

The first stage of fine crushing: The material after being broken by the pretreated single-roller shredder is fed into the crusher, the fine crushing size is 20mm, and the material after fine crushing is dehydrated by friction and then fed to the first stage for rinsing.；

The first stage of rinsing: The metal springs and other harmful substances contained in the bottle flakes have all been separated from the bottle flakes after being shredded through the first stage of the first stage, and after being broken up by friction, they enter the first stage of the pool for rinsing. During the rinsing process, most of the metal springs, aluminum foil and other submerged PET bottle flakes and PE/PP bottle flakes with a specific gravity greater than 1 are removed, and most of the organic pollutants contained in the material are cleaned and dehydrated.；

High-temperature hot-washing module: After finely crushing and dehydrating the material, most of the labels and bottle flakes have been separated. Only the self-adhesive and hot-melt aluminum foil in the bottle flakes have not been separated. Most of the labels are separated through the first stage of sorting and then enter the hot-washing and high-temperature cooking friction. The stubborn dirt, self-adhesive and aluminum foil on the surface of the bottle flakes are rubbed and removed by high-temperature cooking and adding cleaning agents to ensure that the bottle flakes return to their original color; The high-temperature cooking module requires a control temperature greater than 90℃ and cooking for more than 30 minutes. In order to ensure that the temperature and time are up to standard, the production line designs two heating tanks to work alternately. To ensure the quality of cleaning；

ØThree-stage rinsing module: The three-stage rinsing module uses a pool for floating eluting water, which is mainly used to remove cleaning agents and floating and sinking bottle flakes. It is mainly used to add clean water for the final bottle flakes rinsing quality control to obtain the highest purity bottle flakes.；
