AI Technical Summary

Technical Problem

Existing biogas slurry spraying devices are easily clogged by incompletely decomposed particulate matter, resulting in uneven atomization and resource waste. Furthermore, traditional filtration structures cannot completely remove fine particulate matter, affecting operational efficiency and resource utilization.

Method used

The system uses a drive motor to rotate the spiral blades and crushing blades on the rotating rod for compound crushing. Combined with dual-screen filtration, large particles are first crushed into small particles, and then a uniform mist is formed through a booster pump and atomizing nozzle to ensure the spraying effect.

Benefits of technology

It significantly improves pulverization efficiency, reduces the risk of clogging, increases the adhesion rate of droplets on crop leaves, reduces resource waste and environmental pollution, and improves operational efficiency.

Abstract

This utility model discloses a biogas slurry pressure atomizing spraying device, including a housing. A housing cover is threaded onto the top surface of the housing, and a first sealing ring is provided between the housing cover and the housing. A drive motor is fixedly installed on the top surface of the housing cover, and a rotating rod is installed at the output end of the drive motor. In this utility model, the drive motor drives the rotating rod to rotate, causing the spiral blades and the crushing blades to form a composite crushing mechanism. The spiral blades are designed to lift large particles, such as straw fragments and manure residue, from the bottom of the housing and turn them over to the action area of ​​the crushing blades. The crushing blades shear and impact the particles at a blade angle of 60°-75°, crushing particles with a diameter >100μm to 20-50μm. The crushing efficiency is significantly improved compared to traditional stirring devices, which is beneficial for subsequent atomizing spraying, reduces the risk of particle clogging of the nozzle, reduces the possibility of atomization interruption or uneven atomization, and ensures operational efficiency.
