AI Technical Summary

Technical Problem

Existing compressor intake solutions suffer from problems such as large space occupation, difficult installation and layout, high maintenance costs, limited noise reduction effect, and dust accumulation and blockage, failing to meet the comprehensive requirements of cleanliness, low noise, and cost control.

Method used

Design a structure that integrates filtration and noise reduction functions, including a front cover, a rear cover, a filter assembly, and noise reduction cotton. An airflow channel is formed by staggered baffles, and airflow filtration and noise reduction are achieved by combining a filter paper box and noise reduction cotton. A quick-connect connector is used for convenient connection.

Benefits of technology

It effectively filters dust before the compressor intake, reduces noise, simplifies installation and maintenance processes, lowers costs, extends equipment life, and improves user experience.

Abstract

The utility model discloses a filter noise reduction structure for compressor air intake, which comprises a front cover plate, a rear cover plate and a filter component, the front cover plate and the rear cover plate are fixedly connected to form an internal cavity, and a plurality of baffles and noise reduction cotton are arranged in the internal cavity; an air inlet and an air outlet are formed in the filtering assembly; a mounting cavity is formed in the upper part of the front cover plate, a filter assembly is detachably mounted in the mounting cavity, and an exhaust port is formed in the bottom of the rear cover plate; the length of the baffles is smaller than that of the inner cavity, the baffles are arranged in a staggered mode, and airflow channels are formed among the baffles arranged in the staggered mode. The filtering and silencing functions are integrated in the same structure, a traditional discrete scheme is replaced, the double-layer effects of filtering and silencing can be achieved before air inflow of the compressor, meanwhile, the occupied space of equipment is reduced, the installation and layout difficulty is lowered, the installation and maintenance process is simplified, and then the comprehensive cost is reduced.
