Abstract

An air cleaner is an improvement of a part structure in an air compressor. An air output pipe is arranged in the center of the shell of the air cleaner and a filtrating core is sleeved round the air output pipe. The utility model is characterized in that: a nut and a mating ring is tightly compressed on a shell, a round guide plate which has a same circle center with the shell is arranged in the shell, and an air input pipe is connected along the line-cutting direction of the guide plate. The utility model has the advantages that: the structure is more rational, the air flow resistance is reduced in operation, the air impacting phenomena is weakened, the noise is reduced and therefore the noise pollution to the around environment is reduced.

Description

Air filter

(1) technical field

The utility model relates to the improvement of a modular construction in a kind of air compressor, is a kind of air filter specifically.

(2) background technology

Air filter is parts in the air compressor, and its effect is that air is carried out drying, dedusting, sends into compressor then and compresses.The air admission hole that the major defect of existing air filtering device structure is an air from the end cap and the air admission hole of housing bottom enter simultaneously, cause the lower surface of gas shock end cap and the upper surface of housing bottom, the air-flow running resistance is bigger, the gas shock phenomenon is more serious, thus when operation produce very big noise, in addition, air-flow is not smooth in the vertical connecting place operation with the housing bottom surface of deflector, the gas shock phenomenon takes place, and also produces noise, to around cause serious noise pollution.

(3) summary of the invention

The utility model purpose is to overcome the shortcoming in the above-mentioned technology, a kind of architecture advances is proposed air filter, its when operation gas-flow resistance is reduced, reduce noise, reduce noise pollution to surrounding environment.

The utility model purpose is realized by following technical scheme: this air filter, escape pipe is housed in the middle of housing, filter core is sleeved on around the escape pipe, it is characterized in that end cover being pressed on above the housing by nut, packing ring, circular blast baffle with the housing concentric is arranged in the housing, be connected with air inlet pipe along the deflector tangential direction.

Has only a circular hole that is positioned at the connection air inlet pipe of housing side on the housing of air filter.Air inlet pipe generally is positioned at the middle part of the housing side of air filter.Housing bottom has not had air admission hole, has not had air admission hole on the end cover yet.Gas enters along the deflector tangential direction from air inlet pipe, is flowed out by escape pipe by filter core again, and gas-flow resistance is little, and the gas shock phenomenon alleviates, thereby has reduced noise.Through test, before comparing improvement, reduced about 30% the noise that the air filter after the improvement produces when work.

The utility model advantage is that structure is more reasonable, and gas-flow resistance reduces during operation, and the gas shock phenomenon alleviates, and has reduced noise, has reduced the noise pollution to surrounding environment.

(4) description of drawings

Fig. 1 is a kind of air filtering device structure schematic diagram that the utility model proposes,

Fig. 2, Fig. 3, Fig. 4 are front view, vertical view, the side views of this air filter housing,

Fig. 5 is the air filter housing structural representation that improves in the preceding background technology,

(5) specific embodiment, accompanying drawings

This air filter is equipped with escape pipe 6 in the middle of housing 5, filter core 4 is sleeved on around the escape pipe 6, by nut 1, packing ring 2 end cover 3 is pressed on above the housing 5, does not have air admission hole on the end cover 3.Circular blast baffle 51 with the housing concentric is arranged in the housing 5, be connected with air inlet pipe 52 along deflector 51 tangential directions.Except the circular hole of a connection air inlet pipe 52 that is positioned at the housing side, the bottom surface does not have other air admission hole on the housing 5.Air enters along deflector 51 tangential directions from air inlet pipe 52, is flowed out by escape pipe 6 by filter core 4 again, and gas-flow resistance is little.

Air filter housing structural representation from the background technology of Fig. 5 before improving as can be seen, housing bottom originally has air admission hole 53.

Claims

1, a kind of air filter, in the middle of housing escape pipe is housed, filter core is sleeved on around the escape pipe, it is characterized in that by nut, packing ring end cover being pressed on above the housing, circular blast baffle with the housing concentric is arranged in the housing, be connected with air inlet pipe along the deflector tangential direction.

2,, it is characterized in that the circular hole that on housing, has only to be positioned at the connection air inlet pipe of housing side according to the described air filter of claim 1.
