Embodiment

Below in conjunction with accompanying drawing, the utility model polystyrene foamed capacity-reduction device is described in further detail.

As shown in Figure 1, the capacity-reduction device of polystyrene foamed, base 1 is arranged at its bottom, drive unit and bearing support 5 are installed on the base 1, bearing support 5 tops are equipped with to subtract and hold bucket 6, described drive unit has drive-motor 2, drive-motor 2 connects driving pulley 3, belt 21 is housed on the driving pulley 3, belt 21 connects driving pulley 3 and negative pulley wheel 4, there is bearing described bearing support 5 the insides, axle 7 passes bearing, the two ends of axle 7 connect negative pulley wheel 4 respectively and subtract the whipping appts that holds bucket 6, described whipping appts comprises movable knife disc 11 and moving knife 12, moving knife 12 is fixed on the movable knife disc 11, movable knife disc 11 is fixed on an end of axle 7, subtracting the stationary knife 15 that also is provided with on the bucket wall that holds bucket 6 with moving knife 12 cooperatings, stationary knife 15 is fixed on by stationary knife seat 16 and subtracts the inwall that holds bucket 6, also be provided with refrigerating unit subtracting to hold on the bucket 6, described refrigerating unit comprises cooling water channel 14 and cooling air channel 13, cooling water channel 14 is positioned to subtract and holds bucket bottom separate space, cooling air channel 13 is positioned to subtract and holds bucket bucket wall separate space, subtract appearance bucket 6 tops head tank 17 is arranged, head tank 17 tops are opening for feed 8, subtract appearance bucket 17 bottom bucket walls and be provided with discharge port 10, described head tank 17 middle parts are provided with observation port 9, and the bottom sidewall holds bucket 6 and is hinged by hinge 20 with subtracting, and on the described base 1 column 18 is arranged, the top of column 18 is connected with cylinder 19, and the other end of cylinder 19 links to each other with the top of head tank 17.
