Problems solved by technology

However, because it is not easy to age and is difficult to degrade, it has caused serious white pollution.
As far as its volume is concerned, air accounts for 98%, and resin components account for about 2%. It is bulky and inconvenient to transport, which causes great difficulties in its recycling.
In order to recycle expanded polystyrene materials, it must be crushed first. Most of the traditional crushing devices use single-axis crushing knives, and the blades of the crushing knives are generally fixed on the knife shaft at the same angle. This structure leads to The crushing of the expanded polystyrene material is not complete, resulting in that the broken expanded polystyrene material cannot be completely melted, which is likely to cause blockage of the hot melt recycling machine and increase the energy consumption of the machine

Embodiment Construction

[0010] Below in conjunction with the accompanying drawings, the present invention will be further described in detail with a double-shaft crushing knife for a hot-melt recovery machine of expanded polystyrene.

[0011] like figure 1 , figure 2 As shown in the figure, the hot-melt recycling machine of foamed polystyrene uses a double-shaft crushing knife, two knife shafts 1 placed in parallel, a blade 2 is symmetrically fixed on the two knife shafts 1, and a blade 2 on the two knife shafts 1 is symmetrically fixed. They are arranged in mutual dislocation, and the blades 2 on each cutter shaft 1 are evenly arranged on the cutter shaft 1 in the same direction and at an equal angle. The first blade 21 and the last blade 22 on each cutter shaft 1 are clamped at 90°. angle α.

[0012] The working principle of the present invention is as follows: image 3 As shown in the figure, the double-shaft crushing knives installed in the hot-melt recycling machine of foamed polystyrene, be...

Abstract

The invention discloses a double-shaft crushing cutter for a hot melting recycling machine of expanded polystyrene, comprising two cutter shafts arranged in parallel; blades are symmetrically fixed on the two cutter shafts and mutually staggered; and adjacent blades on each cutter shaft are arranged on the cutter shaft and staggered a center angle in the same direction. The invention is suitable for the hot melting recycling machine of expanded polystyrene.

Description

technical field [0001] The invention relates to the field of recovery devices for expanded polystyrene, in particular to the field of crushing knives used in hot-melt recovery machines for expanded polystyrene. Background technique [0002] Due to its closed structure, expanded polystyrene has excellent cushioning, thermal insulation, waterproofing and buoyancy properties. In addition to being used as heat-insulating building materials, ceiling materials, civil engineering materials, etc., it is mainly used as packaging materials, food containers, and the like. However, because it is not easy to age and degrade, it causes serious white pollution. In terms of its volume, air accounts for 98%, and resin components account for about 2%. It is bulky and inconvenient to transport, which causes great difficulties in its recycling. To recycle the foamed polystyrene material, it must be crushed first. Most of the traditional crushing devices use single-axis crushing knives. The bl...
