Abstract
The utility model discloses an air filter and belongs to the field of air filtering equipment. The air filter structurally comprises an upper end cover and a lower end cover; an inner core and an outer core are fixedly mounted between the upper end cover and the lower end cover, and the outer core is sleeved outside the inner core; the outer core comprises inner-layer filter paper and outer-layer filter paper, and the outer-layer filter paper is sleeved outside the inner-layer filter paper; and the internal surface of the inner-layer filter paper is fixed onto an inner support, and the external surface of the inner-layer filter paper and the internal surface of the outer-layer filter paper are fixed onto a middle support. Compared with the prior art, the air filter has the advantages of being reasonable in design, simple in structure, easy to process, high in filtering precision and the like, reduces the pollution degree of an engine and prolongs the service life of the engine.
Description
Technical field
The utility model relates to the air filter unit field, specifically a kind of air-strainer.
Background technique
During reciprocating machine (internal-combustion engine, reciprocating compressor etc.) work; if the impurity such as dust that contain in the suction air; wearing and tearing with the aggravation mechanical parts; reduce the working life of machinery greatly; for avoiding impurity such as dust to the infringement of machinery; people usually can mechanically be equipped with air-strainer at this, are used in the filtered air impurity such as dust.Normally used air-strainer mainly is made of inner core and outer core, and the outer core of the filter cleaner that uses is individual layer filter paper structure at present, and this single layer structure filters not thorough, is easy to cause the pollution of filter cleaner inner core, makes engine scuffing easily.
Summary of the invention
Technical assignment of the present utility model is at above deficiency, and a kind of simple in structure, a kind of air-strainer that filter precision is high is provided.
The technological scheme that its technical problem that solves the utility model adopts is: this air-strainer comprises upper end cap and lower end cap, is installed with inner core and outer core between upper end cap and the lower end cap, and outer core retainer plate is in the outside of inner core; Outer core comprises internal layer filter paper and outer filter paper, and outer filter paper is enclosed within the outside of internal layer filter paper, and the internal surface of internal layer filter paper is fixed on the inner support, and the outer surface of internal layer filter paper and the internal surface of outer filter paper are fixed on the intermediate support.
Described internal layer filter paper and outer filter paper are all for being folded into corrugated filter paper.
A kind of air-strainer of the present utility model is compared with prior art, have reasonable in design, simple in structure, be easy to characteristics such as processing, filter precision height, reduced the pollution level of motor, prolonged the working life of motor.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing 1 is a kind of structural representation of air-strainer.
Accompanying drawing 2 be in the accompanying drawing 1 A-A to sectional view.
Among the figure: 1, upper end cap, 2, lower end cap, 3, inner support, 4, intermediate support, 5, internal layer filter paper, 6, outer filter paper, 7, inner core, 8, outer core.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
A kind of air-strainer of the present utility model, its structure comprise upper end cap 1 and lower end cap 2, are installed with inner core 7 and outer core 8 between upper end cap 1 and the lower end cap 2, and outer core 8 is enclosed within the outside of inner core 7; Outer core 8 comprises internal layer filter paper 5 and outer filter paper 7, and outer filter paper 7 is enclosed within the outside of internal layer filter paper 5, and the external diameter of outer filter paper 7 is identical with the external diameter of the outer core of conventional filter, more convenient like this installation.The internal surface of internal layer filter paper 5 is fixed on the inner support 3, and the internal surface of the outer surface of internal layer filter paper 5 and outer filter paper 6 is fixed on the intermediate support 4; Internal layer filter paper 5 and outer filter paper 6 are all for being folded into corrugated filter paper.
Its processing and fabricating of a kind of air-strainer of the present utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except the described technical characteristics of specification, be the known technology of those skilled in the art.
