AI Technical Summary

Technical Problem

Waste removal during existing wood processing is difficult, especially the accumulation and cleaning of sawdust, which affects the working environment and health.

Method used

The system employs a combination of negative pressure fans, collection hoods, filters, and dust collection devices. The negative pressure fans draw in wood chips, which are then initially filtered by the filters. The wood chips are collected in stages, and the filtration efficiency is improved by combining a vibrating motor and atomizing nozzles. A star-shaped discharge valve and a spiral dust collection chamber are used to reduce accumulation, and the air valve control equipment is activated to reduce costs.

Benefits of technology

It effectively reduces the wear and tear on the negative pressure fan caused by sawdust, improves the filtration and collection efficiency of sawdust, reduces accumulation, reduces cleaning difficulty, and lowers equipment costs.
