Description

Large-capacity excavator filter

Technical Field

The utility model relates to an excavator filter of large capacity.

Background

Apparatus for removing particulate impurities from air. When a piston machine (an internal combustion engine, a reciprocating compressor, etc.) operates, if impurities such as dust are contained in intake air, abrasion of parts is increased, so that an air cleaner must be installed.

The air filter consists of a filter element and a shell. The main requirements of an air cleaner are high cleaning efficiency, low flow resistance, and continuous use for a long time without maintenance.

Air filters (Air filters) are mainly used in the fields of pneumatic machinery, internal combustion machinery and the like, and are used for providing clean Air for mechanical equipment so as to prevent the mechanical equipment from sucking Air with foreign particles in work and increase the probability of abrasion and damage. The main components of an air cleaner are a filter element, which is the main filtering part, which undertakes the filtering of the gas, and a housing, which is the external structure that provides the necessary protection for the filter element. The air cleaner is required to be capable of performing high-efficiency air cleaning operation, not to increase excessive resistance to air flow, and to be capable of continuous operation for a long time.

During the working period of the excavator, diesel oil needs to be combusted, combustion-supporting air needs to be continuously provided, so that the pollution speed of the filter element is high, and meanwhile, due to the negative pressure generated when the engine enters air, tiny dust in the filter element can be brought in, and the abrasion of the diesel engine is aggravated.

Based on the problems, the large-capacity excavator filter which adopts a double-filtering structure and has a safety function is designed.
