AI Technical Summary

Technical Problem

In building ventilation ducts, inaccurate airflow control leads to energy waste and decreased air quality, and filters are prone to clogging, affecting ventilation efficiency.

Method used

By adjusting the number of perforated plates on the filter screen and combining this with sensor-detected airflow, the airflow is adjusted using an electric push rod and regulating mechanism. The filter screen vibrates and backflushes to prevent clogging, and magnetic and elastic structures are used to promote dust removal.

Benefits of technology

It achieves precise airflow control, reduces energy consumption, extends filter life, maintains air quality, prevents dust accumulation, and improves ventilation.

Abstract

The invention belongs to the technical field of building ventilation, and particularly relates to an air volume control method of a pipeline type ventilation device, which comprises the following steps: S1, detecting the air volume passing through a ventilation pipeline through a sensor mounted on the ventilation pipeline; s2, the detected air volume is compared with a set value, and the adjusting amount of the air volume is determined; s3, the controller adjusts the position of a second mesh plate in the adjusting link according to the adjusting quantity of the air volume, the air volume conveyed in the ventilation pipeline is changed, and the air volume reaches a set value; the device is simple in structure, the air volume is controlled by adjusting the number of the second mesh plates pressing the filter screen and changing the ventilation area in the adjusting link, meanwhile, the filter screen can be vibrated and backwashed, dust and impurities on the filter screen are promoted to fall off, and the filter screen is prevented from being blocked.
