AI Technical Summary

Technical Problem

Existing wood crushing equipment suffers from problems such as low separation efficiency, high equipment resistance, high energy consumption, and easy clogging in dust treatment, making it difficult to meet high emission standards, affecting production continuity and increasing maintenance costs.

Method used

The system employs a rotating screen plate in the separation chamber for initial separation, a spiral flow field in the conical cylinder for secondary separation, and a scraper and brush assembly to clean the screen plate. The vibration of the vent plate prevents clogging, thus achieving multi-stage separation and automatic cleaning.

Benefits of technology

It improves dust separation efficiency and recovery rate, ensures the cleanliness of exhaust gas, prevents dust adhesion and blockage, and maintains long-term stable operation of the equipment.

Abstract

The invention relates to the technical field of dust treatment, and discloses a wood crushing equipment dust treatment device which comprises a separation box and further comprises a conical barrel connected to the outer wall of the separation box through two fixing rings; the guide pipe is connected between the separation box and the conical barrel, a cylindrical cavity is formed in the separation box, one end of the guide pipe is located at the tangent line of the cylindrical cavity, and the other end of the guide pipe enters in the tangent line direction of the conical barrel; the feeding pipe is mounted on one side of the separation box and used for guiding wood dust into the separation box; and the separating mechanism is arranged in the cylindrical cavity of the separating box and used for primarily separating wood dust. According to the invention, primary efficient separation of dust is realized through direct interception of the rotating sieve plate in the separation box, then gas forms a reinforced spiral flow field in the conical barrel, secondary capture is carried out on fine dust by using centrifugal force, and the overall separation efficiency and recovery rate of dust with different particle sizes are greatly improved through a combined separation process; and the cleanliness of the discharged gas is ensured.
