A compound drum bag breaking device for bagged domestic garbage

Abstract

The invention discloses a combined roller bag breaking device for household garbage in bags. The bag breaking device belongs to the field of environment protection equipment and comprises a draught fan assembly, an inner roller, an outer rolling ring and a base assembly. The inner roller is sleeved with the outer rolling ring. The inner roller and the outer rolling ring are each supported by a rolling wheel supporting mechanism on the base assembly. The outer rolling ring is provided with bag breaking nails, and the bag breaking nails are inserted in kidney-shaped holes in the inner roller. The draught fan assembly is arranged at the end, with the inclined face higher, of the base assembly. The wind direction of an axial flow draught fan directly faces the upper side face of the inner wall of the inner roller. When the household garbage in bags is placed therein through the high end of the inner roller, a speed reduction motor drives the inner roller to rotate; the bag breaking nails drive the outer rolling ring to rotate; and meanwhile, the bag breaking nails are inserted into and pulled out of the kidney-shaped holes in a reciprocating manner, so that the garbage bags are punctured, under the wind action of the axial flow draught fan, the garbage bags fall off the bag breaking nails, and garbage is collected through a special collection box. By means of the combined roller bag breaking device, the bag breaking effect is enhanced; bag breaking efficiency is improved; and the combined roller bag breaking device is simple in structure and great in practicability.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, in particular, it relates to a composite drum bag breaking device for bagged domestic garbage. Background technique [0002] During the processing of bagged domestic waste, it is generally necessary to break the bags of bagged waste for subsequent sorting. The drum of the existing garbage bag breaking device is equipped with fixed blades. During the bag breaking process, the garbage is easy to stick and stay on the bag breaking nails and the wall of the drum. The bag breaking efficiency is low, which is not conducive to garbage classification and affects the bag breaking effect. How to avoid affecting the effect of bag breaking due to long-term working garbage adhesion is an important issue in the design of garbage bag breaking devices. In order to solve this problem, the present invention proposes a composite drum bag breaking device. Contents of the invention [0003] The m...
