Abstract

The invention relates to an ultrasonic-enhanced auxiliary low-resistance high-efficiency multistage air filter. The ultrasonic-enhanced auxiliary low-resistance high-efficiency multistage air filter comprises an outer shell, a first-stage ultrasonic rotational flow filtering system, a second-stage ultrasonic dust removal filtering system, a third-stage fine filtering system and a main ultrasonic automatic dust discharging and collecting system. The main ultrasonic automatic dust discharging and collecting system is arranged under the filter. The first-stage ultrasonic rotational flow filteringsystem is arranged above the main ultrasonic automatic dust discharging and collecting system. The second-stage ultrasonic dust removal filtering system is arranged directly above the first-stage ultrasonic rotational flow filtering system. The third-stage fine filtering system is arranged directly above the second-stage ultrasonic dust removal filtering system. When the working condition of an engine changes, a dust concentration signal sensor collects dust concentration signals in the filter and transmits the signals to an ECU, and the ECU controls the parameters of an ultrasonic device toimprove the filtering efficiency of the filter. The ultrasonic-enhanced auxiliary low-resistance high-efficiency multistage air filter can effectively overcome the defects that a traditional desert air filter is poor in filtering effect, short in maintenance period and the like, and has the beneficial effects of being high in air filtering efficiency, long in maintenance period and the like.

Description

Technical field [0001] The present invention relates to the technical field of ultrasound dust, particularly to a reinforced ultrasonic assisted low resistance high efficiency multi-stage air cleaner. Background technique [0002] Effects of the intake of dust on the internal parts wear power system is the largest in the impact of various factors, severe cases may also lead to insufficient power system dynamics, or even overhaul. The air cleaner is on a power system, a very important part, the main function of intake air to filter dust and impurities, to provide a clean, dry, sufficient air-cylinder combustion participation, to minimize the power system due to rounding wear and maintain good power performance caused by the gas particles. At present, most of my country's construction machinery environment is relatively harsh working conditions in, most have adopted a multi-stage air filter. Also known as multi-stage air cleaner desert air filter, most of the air cleaner desert mul...
