Abstract

An automatic speed regulating device of a dust removal fan comprises a dust fall quantity detector, a circuit conversion device, a frequency changer and a fan motor which are connected in sequence. The dust fall quantity detector comprises an air suction system, a detecting device, a single chip computer system and a detector power source, the circuit conversion device comprises a D / A conversion circuit and a pulse output circuit, the air suction system sucks fall-dust air at a fall-dust air inlet through suction of a fan, the detecting device receives scattered light and converts the scattered light to light currents, the circuit conversion device is used for converting and outputting pulse signals, and the frequency changer receives the pulse signals and regulates the speed of the fan motor in a frequency changing mode. The revolving speed of the fan can be automatically adjusted according to dust content in the environment, and finally the power saving effect is achieved.

Description

technical field [0001] The invention relates to a power control device of a dust-removing fan, in particular to an automatic speed-regulating device of a dust-removing fan. Background technique [0002] Most of the dust removal fans on the market now use AC frequency conversion speed regulation. By manually adjusting the frequency of the frequency converter to control the speed of rotating machinery such as fans and water pumps, the purpose of adjusting the air volume and flow is achieved. This is of great significance to saving energy and improving economic efficiency. This kind of manual operation is blind, and the speed of the fan cannot be adjusted accurately according to the dust content in the air, resulting in incomplete dust removal and energy waste. Contents of the invention [0003] In order to overcome the defects of the existing dust removal fan, the invention provides an automatic speed regulating device which solves the existing problems of the dust removal ...
