Problems solved by technology

[0004] However, its air intake is relatively large, and it is easy to generate a lot of noise at the air intake
The usual method is to install louvers at the air inlet. Although the louvers can reduce noise to a certain extent, they still cannot meet the noise requirements of current blowers.

Abstract

The invention relates to the technical field of air intake silencing, and discloses an air intake silencing device and an air blower. The air intake silencing device comprises a shell, a plurality oflouvers and at least two sound-absorbing baffles, wherein the shell is provided with an air inlet and an air outlet; the plurality of louvers are arranged at the air inlet at intervals; the at least two sound-absorbing baffles are arranged in the shell at intervals along the airflow direction; the roots of two adjacent sound-absorbing baffles are respectively and fixedly connected with the opposite inner walls of the shell; and the free ends of the two adjacent sound-absorbing baffles are respectively spaced from the opposite inner walls of the shell. According to the air intake silencing device, the louvers can absorb part of noise generated by air flowing when the air enters the shell; the two adjacent sound-absorbing baffles are arranged in such a way that the air can zigzag circulate in the shell, and when the air impacts the sound-absorbing baffles, the sound-absorbing baffles can absorb the noise of the air flowing in the shell; and the louvers and the sound-absorbing baffles arematched to absorb most of the noise during air intake, so that the requirement of the air blower for low noise is met.

Description

technical field [0001] The invention relates to the technical field of air intake noise reduction, in particular to an air intake noise reduction device and a blower. Background technique [0002] Magnetic levitation blower is a kind of mechanical equipment for conveying gas. It adopts core technologies such as magnetic levitation bearing, ternary flow impeller, high-speed permanent magnet synchronous motor, high-efficiency frequency converter speed regulation, intelligent monitoring and control, etc. When starting, it levitates first and then rotates without friction. , without lubrication, the ternary flow impeller is directly connected to the rotor, and the transmission has zero loss. It is a high-tech green energy-saving and environmental protection product. [0003] Magnetic levitation blower adopts non-contact, non-mechanical friction magnetic levitation bearing and high-speed high-power permanent magnet synchronous motor to directly drive the high-efficiency fluid im...
