Technical Field

The invention relates to the technical field of dust collectors, in particular to an intelligent variable frequency control system and a dust collector.

Background

The existing dust collector generally has no frequency conversion function and can not achieve the purpose of energy saving. Variable frequency cleaners have also been proposed, such as the one disclosed in patent No. 98225571.3. The existing variable frequency dust collector adopts a variable frequency power supply for frequency conversion, and the variable frequency power supply is heavy and heavy, so that the normal use of the dust collector is influenced. At present, a variable frequency controller of the dust collector does not exist for carrying out variable frequency control so as to reduce the volume and weight of the dust collector.

Chinese patent application No. CN103405195A discloses a stepless frequency conversion control method for a dust collector, which adopts a thyristor as a frequency conversion switch device of a dust collector motor; when the dust collector works, the current of the motor of the dust collector is detected, the current power of the motor of the dust collector is calculated according to the detected working current of the motor of the dust collector, then the current power is compared with the control power of the motor of the dust collector when the dust collector is normally unblocked, and the control angle of the silicon controlled rectifier is adjusted according to the comparison result, so that the purpose of frequency conversion is achieved. A special frequency conversion controller of the method comprises the following steps: a current detection module; an A/D conversion module; an MCU for calculating and transmitting instructions; a controlled thyristor. The invention provides a stepless frequency conversion controller of a dust collector, which realizes frequency conversion control of a motor of the dust collector and greatly reduces the volume and the weight of the dust collector. The method can only carry out frequency conversion control according to the current of the dust collector, and cannot control the intelligent opening and closing of the dust collector.
