Black soldier fly larva screening device for treating kitchen garbage

Abstract

The invention relates to the technical field of garbage treatment, in particular to a black soldier fly larva screening device for treating kitchen garbage. According to the technical scheme, the black soldier fly larva screening device for treating the kitchen garbage comprises a hollow shell, and a separation part is arranged in the shell; the shell is divided into a feeding cavity and a transition cavity by the separation part, and the separation part is provided with a plurality of channels for black soldier fly larvae to pass through; the feeding cavity is provided with a feeding port capable of being opened and closed; the transition cavity is provided with an air inlet and an air outlet, and the air outlet is used for being connected with a negative pressure fan; and the transitioncavity is further connected with an insect storage cavity, the upper end of the insect storage cavity is communicated with the lower end of the transition cavity, the air outlet is located above the insect storage cavity, and an insect taking door is arranged at the bottom of the insect storage cavity. According to the black soldier fly larva screening device, hatched larvae and hatched bases canbe rapidly separated, it is guaranteed that when the black soldier fly larvae are thrown into the kitchen garbage, accurate metering is achieved, the larva screening efficiency is improved, and then the treatment efficiency of the kitchen garbage is guaranteed.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a black soldier fly larva screening device for treating kitchen waste. Background technique [0002] Kitchen waste refers to the waste generated in the daily life of residents and activities such as food processing, catering services, and unit meals, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea dregs, bones, etc. The main sources are home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. Kitchen waste contains extremely high moisture and organic matter, which is easy to rot and produce stench, but it can be transformed into new resources after proper treatment and processing. The high organic matter content makes it suitable for fertilizer and feed after strict treatment. Biogas can also be produced for fuel or power generation, and the fat fraction can be used to make biofu...

AI Technical Summary

Problems solved by technology

If the larvae mixed with the hatching substrate are directly weighed, the actual number of larvae will be quite different from the required number of larvae, and it will be difficult to ensure that the kitchen waste can be completely decomposed, which will affect the treatment efficiency of kitchen waste

If the hatched larvae climb out of the hatching tray by themselves, the waiting time is too long, and it is difficult to meet the needs of automatic processing of kitchen waste
