Description

Technical Field:

[0001] The utility model relates to the technical field of crushing and separating equipment, and more specifically to a perishable garbage crushing device with light material separation. Background Art:

[0002] At present, the work of domestic waste classification has been gradually carried out in cities across the country. Domestic waste is divided into four categories: kitchen waste, recyclable waste, hazardous waste, and other waste. Currently, kitchen waste is generally contained in kitchen waste garbage bags. When dealing with kitchen waste, the bagged kitchen waste is generally directly pretreated, and subsequent conversion and reuse can be achieved through anaerobic fermentation (for the wastewater of kitchen waste) or aerobic composting (for the perishable garbage of kitchen waste). In the pretreatment, it includes processes such as feeding, bag breaking, crushing and separating, and dewatering. Among them, the crushing and separating is carried out in the light material crushing and separating equipment. Currently, there are two sets of opposite crushing rollers in the crushing and separating equipment. The crushing rollers cut and crush the kitchen waste after bag breaking, and the crushed garbage enters two sets of opposite separating rollers. The separating rollers are provided with separating rods (equivalent to hanging rods) that can move telescopically on the separating rollers and rotate with the separating rollers. The crushed kitchen waste garbage bags and some light materials of the kitchen waste are hooked on the separating rods between the separating rollers, and move to both sides of the separating rollers with the separating rods and retract into the separating rollers, realizing separation from the light materials. The light materials are discharged from both sides of the two sets of separating rollers.

[0003] Currently, the telescopic movement of the separating rod is mainly driven by a guide rail mechanism with an eccentric wheel structure arranged inside the separating roller. The separating rod is actually installed and screwed on the connecting shaft of the guide rail mechanism (the structure is disclosed in the patent document with the patent number CN201611048250.8). During the operation of the crushing and separating equipment, the separating rod is in contact with kitchen waste and seepage water for a long time, and is easily corroded. Regular maintenance and replacement are required. When replacing, the separating rods need to be unscrewed one by one and then new separating rods are screwed and installed, resulting in troublesome maintenance and replacement. Therefore, a structure that facilitates the installation and disassembly of the separating rod needs to be designed. Summary of the Utility Model:
