Description

High-flux excavator filter

Technical Field

The utility model relates to an excavator filter of high flux.

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.

However, the excavator is special in working occasions and has a large amount of dust in a working site, so that the filtering pressure of the air filter is high, the service life of the air filter is short, dust in an engine is often caused to enter, and the service life of the engine is shortened.

Based on the above, we have designed a high flux excavator filter that can double filter the air entering the engine.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that an excavator filter of high flux that can carry out double filtration to the air that gets into the engine is provided.

The utility model discloses a realize through following technical scheme:

the utility model provides a high flux's excavator filter, includes air filter, still includes a box body the left side position department of box body is provided with a lid that can open, the box body with be connected with the flange between the lid, the inside upper and lower of box body is provided with two baffles, two install between the baffle air filter be provided with a plurality of bar grooves that use through the air current on the face of baffle the bottom of box body is provided with an intake pipe, and the right side of box body is provided with a plurality of screw holes, the screw hole is located the top position department of baffle, through the screw hole is equipped with the thick filter equipment of air.

Preferably, the air coarse filtering device comprises an outer shell, the left end of the outer shell is formed with an inner pipe by injection molding, the left end of the inner tube is provided with a thread part matched with the threaded hole, the right end of the inner tube extends to the inside of the outer shell, the inner pipe and the outer shell are coaxially arranged, air inlets are uniformly distributed on the part of the inner pipe positioned in the outer shell, a coarse filter core is sleeved on the part of the inner pipe positioned in the outer shell, a shell cover is assembled at the right end of the shell, a threaded rod is processed at the axle center of the left end of the shell cover, the threaded rod is in threaded connection with the inner tube, a pressure plate is formed at the outer wall of the threaded rod through injection molding, the pressing plate is pressed on the coarse filter element, a gap for air to enter is formed between the shell cover and the shell, and an annular metal mesh cover is assembled at the gap.

The actual work occasion dust volume of excavator is huge, including large granule dust, tiny particle dust and micronic dust, we can avoid the entering of large granule dust through the metal mesh enclosure that sets up, and the coarse strainer need be passed after passing the metal mesh enclosure to tiny particle dust and micronic dust, and the coarse strainer can filter most tiny particle dust and part micronic dust, and the air after the filtration just can enter into to the box body, carries out final filtration through the air filter in the box body.

The thick filter equipment of air is installed in the outside of box body, therefore when changing, only need to screw off can, easy operation is convenient, shorten preparation operating time greatly, we are during practical application, prepare several thick filter equipment of air as reserve more, when needs are changed, only need shut down 3 ~ 5 minutes, the thick filter equipment of air that will need to be changed takes off, new in the replacement can, the old colating element to inside that changes down changes, adopt the air-blowing again to clean, can reuse.

Preferably, a polygonal stressed part is formed at the right end axle center of the shell cover in an injection molding mode.

Preferably, a baffle is formed on the part of the inner pipe, which is positioned outside the outer shell, in an injection molding mode, and when the threaded part is screwed into the threaded hole, the baffle forms a limit.

Preferably, a polygonal first force-bearing part is formed on the part of the inner pipe located outside the outer shell in an injection molding mode.

This product is after the installation is accomplished, and the air at first need pass coarse filtration device, then just can enter into the box body, is discharged after passing air filter again, and double filtration filters more high-efficient, and the loss to the filter core also can reduce simultaneously.

The utility model has the advantages that: this product adopts two kinds of filtration modes of coarse filtration and smart filtration to combine, can reduce air filter's consumption, reduces air filter's dismouting number of times, and the maintenance of easy excavator is protected, and the structure of this product is comparatively simple, and the cost is comparatively cheap, is fit for using widely.
