Foam particle cooling compression device and foam cooling compression method

Abstract

The invention discloses a foam particle cooling and compressing device and a foam cooling and compressing method, and relates to the field of household appliance recycling. The device comprises a screw conveyor, a conveying cylinder comprises an inner sleeve and an outer sleeve, a cooling water jacket is formed between the inner sleeve and the outer sleeve, and the outer sleeve is provided with a water inlet end and a water outlet end which are communicated with the cooling water jacket; an acute included angle is formed between the conveying direction of the screw conveyor and the ground, and the height of the feeding end is lower than that of the discharging end; the volume of a thread groove of the screw rod is gradually reduced from the feeding end to the discharging end; and a horizontal extrusion device is arranged at the discharging end and comprises an extrusion channel, a support and a hydraulic cylinder are arranged on the side edge of the extrusion channel, the hydraulic cylinder is fixed through the support, and a pressing plate is arranged at the bottom of the hydraulic cylinder. The problems that the foam particles recovered and separated through the previous step are high in temperature and dispersed are solved, the foam particles are cooled and pressed, subsequent packaging and transportation are facilitated, and meanwhile production safety is guaranteed.

Description

technical field [0001] The invention relates to the field of home appliance recycling, in particular to a foam particle cooling and compressing device and a foam cooling and compressing method. Background technique [0002] In the recycling of waste home appliances, waste home appliances such as refrigerators usually include polyurethane foam insulation foam. During the recycling process, they are separated by crushing and sorting process steps. The foam particles with higher temperature are relatively loose and higher in temperature, and the direct bagging and packaging takes up a lot of space, and the foam dust with higher temperature is more likely to disperse, posing a fire hazard. [0003] Therefore, there is a need for a device capable of cooling and compacting the treated foam to facilitate subsequent packaging and transportation, while ensuring safe production in the foam particle recovery workshop. Contents of the invention [0004] The purpose of the present inv...
