The utility model discloses a kind of refrigerator heat-insulating
material volume reduction extruding device, it is related to heat-insulating
material recycling field, to solve the problem of higher
transportation cost to broken heat-insulating material in prior art, although volume is smaller after breaking, but space occupancy increases, leading to. Primary compression conveying
pipe is rotatably connected with variable
pitch helical blade inside, one side of primary compression conveying
pipe is fixedly connected with compression box, the compression box is provided with pressing plate in inside upper end, the lower end of the end face of the side of the compression box away from primary compression conveying
pipe is provided with
discharge port, the side of the compression box away from primary compression conveying pipe is fixedly connected with rectangular support frame, the lower end in rectangular support frame inside and outside
discharge port is provided with
discharge baffle, adopt two-stage compression structure design, first through
helical conveying pre-compression, then utilize hydraulic device to carry out final compression, effectively reduce the volume of heat-insulating material.
