Description

Technical Field

[0001] The utility model relates to the technical field of garbage treatment, in particular to a kitchen waste treatment station for black soldier flies. Background Art

[0002] Kitchen waste refers to food residues and waste edible oils produced in residents' daily life and catering activities. Its components include starch, food cellulose and animal fats, which are the main components of the organic phase in urban domestic waste. The general components and physical and chemical properties of urban kitchen waste are as follows: high moisture content: the moisture content of kitchen waste is generally about 75%-90%, and the calorific value of kitchen waste is low, which brings great difficulties to its collection, transportation and treatment; easy to rot: the organic content in kitchen waste is high, accounting for more than 95% of the dry matter mass, and it is easy to rot and stink; rich in nutrients: in addition to the high organic content, kitchen waste is also rich in nitrogen, phosphorus, potassium, calcium and various trace elements, and has complete nutritional elements. Kitchen waste needs to be collected together for treatment, so it needs to be transported, which is time-consuming and laborious to handle. The existing kitchen waste treatment equipment is not environmentally friendly and is prone to odor overflow. Now there is a need for a biological treatment equipment that is environmentally friendly, has a high recycling rate and is odor-free.

[0003] The existing patent application with publication number CN114308984A discloses a black soldier fly treatment kitchen waste bin, which relates to the field of environmental protection technology. Through a height detector, the feeding is stopped after the overall height is about 15 cm, and part of the oil and water contained in the kitchen waste falls to the bottom and is discharged through a discharge port, and then black soldier fly larvae are added from the black soldier fly larvae inlet, and the kitchen waste treatment process is monitored according to the height detector and the observation window. When the added kitchen waste is completely treated or most larvae are close to the prepupa prepupa can crawl autonomously, the vibration pump and the fill light are started to separate the larvae and the residue, and the separated residue falls to the secondary fine screen for collection and treatment, and the larvae are sent to the pupation compartment to pupate in the gap between stones. After the adult insects lay eggs, this compartment can be taken out and the eggs can be hatched. When the garbage bin is used to treat kitchen waste, it is easy to release odor to the outside world, affecting the living environment in the placement area. Utility Model Content
