Embodiment 1

[0032] See attached Figures 1 to 4 , the overall structure of Embodiment 1 of an ultrasound-enhanced assisted low-resistance high-efficiency multi-stage air filter proposed by the present invention is given. The filter includes an outer shell 1, a primary ultrasonic cyclone filter system 2, a secondary ultrasonic dust removal filter system 3, a tertiary fine filter system 4 and a main ultrasonic automatic dust collection system 5; the primary ultrasonic cyclone Filtration system 2, secondary ultrasonic dust removal and filtration system 3 and tertiary fine filtration system 4 are sequentially arranged inside the outer casing 1 from bottom to top, and the main ultrasonic automatic dust removal and ash collection system 5 is arranged at the bottom of the outer casing 1 and connected The first-stage ultrasonic cyclone filtration system is connected to each other.

[0033] The first-stage ultrasonic swirl filter system 2 includes a fixed plate with holes 21, an air inlet 22, a s...

Embodiment 2

[0039] See attached Figures 5 to 7 , the overall structure of Embodiment 2 of an ultrasonic-enhanced assisted low-resistance high-efficiency multi-stage air filter proposed by the present invention is given. The difference between this embodiment and Embodiment 1 is that the swirl tube inlet 232 is set on the left side of the middle part of the swirl tube 23, and a controllable air inlet is installed at the swirl tube inlet 232 Valve 236. According to the tangential airflow at the air inlet, this embodiment adopts a spiral air intake pipe, and a controllable air intake valve 236 is installed in the air intake spiral pipe, and the ECU can automatically adjust the opening of the controllable air intake valve 236 according to the working conditions , so as to obtain the best intake air flow rate.

Embodiment 3

[0041] See attached Figures 8 to 9 , the overall structure of Embodiment 3 of an ultrasonically enhanced assisted low-resistance high-efficiency multi-stage air filter proposed by the present invention is given. The difference between this embodiment and Embodiment 1 is that the ultrasonic transducer 31 is arranged at the center of the outer casing 1, and the ultrasonic transducer 31 is arranged in a circumferential direction, and the dust exhaust tube 32 is The circular type is arranged on the outer side of the ultrasonic transducer 31, and the inner side of the dust exhaust tube 32 is opposite to the ultrasonic transducer 31. Correspondingly, the left and right sides of the bottom of the outer shell 1 are respectively equipped with auxiliary ultrasonic automatic exhaust Dust collection system 33, the two sides of the auxiliary ultrasonic automatic dust collection system 33 respectively communicate with the outer bottom of the dust discharge tube 32 on both sides, and the in...

Abstract

The invention relates to an ultrasonic-enhanced auxiliary low-resistance high-efficiency multi-stage air filter, which includes an outer shell, a first-stage ultrasonic swirl filter system, a second-stage ultrasonic dust removal filter system, a third-stage fine filter system and a main ultrasonic automatic dust collector. Ash system, the main ultrasonic automatic dust removal and ash collection system is arranged directly below the filter, the first-stage ultrasonic cyclone filter system is arranged above the main ultrasonic automatic dust removal and ash collection system, and the second-stage ultrasonic dust removal and filtration system It is arranged directly above the first-stage ultrasonic cyclone filter system, and the third-stage fine filter system is arranged directly above the second-stage ultrasonic dust removal filter system. When the working condition of the engine changes, the dust concentration signal sensor collects the dust concentration signal in the filter, and transmits the signal to the ECU, and the ECU controls the parameters of the ultrasonic device to improve the filtration efficiency of the filter. The invention can effectively solve the disadvantages of poor filtering effect and short maintenance period of the traditional desert air filter, and has the advantages of high air filtration efficiency and long maintenance period.

Description

technical field [0001] The invention relates to the technical field of ultrasonic dust removal, in particular to an ultrasonic enhanced auxiliary low-resistance high-efficiency multi-stage air filter. Background technique [0002] The impact of intake dust on the wear of internal parts of the power system is the largest among various influencing factors. In severe cases, it may lead to insufficient power of the power system or even overhaul. The air filter is a very important part of the power system. Its main function is to filter out the dust and impurities in the intake air, so as to provide clean, dry and sufficient air to participate in the combustion in the cylinder, and to minimize the power system due to intake air. wear caused by gas particles and maintain good dynamic performance. At present, most of my country's construction machinery works in relatively harsh conditions, and most of them use multi-stage air filters. The multi-stage air filter is also called the...
