Abstract
The utility model discloses an air filter core with a spiral type composite metal net. The utility model is characterized in that the bottom and the upper end part of a cavity of an outer housing are respectively connected with two layers of coarse and fine filtering net via a bracket and a clamping cap; at least five convex-shaped diagonal guide flow sheets are arranged on surfaces of through holes of a spiral pipe which is arranged in holes of an air inlet. When operating, the utility model causes the outer air to be respectively filtered by the coarse and the fine filtering net, the dust filtering effect is good, the maintenance and the cleaning are cleanly, and the service life is long; the rotated air stream generated by the diagonal guide stream sheets and the atomization fuel in an engine cylinder are uniformly mixed, the combustion is full, the fuel is saved for 5 %-8%, and the environment pollution is reduced.
Description
The utility model relates to air-intake of combustion engine filtering parts, is specifically related to the engine air filter core.
Engine air filter is to be made of housing and filter element.Said filter element is the critical component of filter cleaner; Usually a kind of is the papery structure, and deficiency is: the dust granules that filters by the papery core easily stops up filter element, and maintenance clean is unclean; Another kind of filter element is the stratiform structure that iron wire twines, and deficiency is: dust granules weak effect in the filtered air is difficult for maintenance clean.All fragile in above-mentioned two kinds of filter element using processs, the life-span is short.In addition, filter element is the direct current type suction tude, during work, directly enters the filtering air of cylinder and mixes inhomogeneously with atomized fuel in the cylinder, and it is insufficient to burn, and has wasted fuel, has polluted environment.
The purpose of this utility model is to provide a kind of Chalk-dust filtering effective, and it is convenient, clean to clean, easy care maintenance and long service life, and fuel saving again reduces the spiral composite metal net air-strainer core of environmental pollution.
The technical solution of the utility model is achieved in that mainly and is made of frame, support, suction tude, friction top; Improvement is: in the bottom and the upper end portion of frame inner chamber, respectively by support and friction top, be connected with thick filtering net and fie screen; In the suction tude mesopore, be provided with on the through-hole surfaces of volute, be connected with at least 5 oblique guide plates of convex.
The utility model adopts said structure, and by thick, the thin two-layer filter screen that the frame inner chamber is provided with, the dust in the filtered air is effective; Maintenance clean is convenient, clean, long service life.By the oblique guide plate that is connected with on the volute through-hole surfaces, during work, make ambient air pass through the spiral air flow that oblique guide plate produces, evenly mix with atomized fuel in the cylinder by suction tude, fully fuel has been saved in burning, has reduced environmental pollution.After tested, than original air-strainer core fuel saving 5-8%.
Below in conjunction with accompanying drawing specific embodiments of the present utility model is elaborated.
Fig. 1 is a sectional front view of the present utility model;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is that the utility model and air filter housing user mode are installed connection diagram.
Fig. 1-shown in Figure 2.Frame 1 intracavity bottom is the through hole shape that 6 connecting tendons link to each other, and 60 purpose Stainless Steel Wire thick filtering nets 7 and suction tude 8 are connected in frame 1 intracavity bottom respectively; The support 6 that has 6 connecting tendons places frame 1 inner chamber, its underpart links to each other with thick filtering net 7, and the upper end portion of support 6 is connected with 100 purpose Stainless Steel Wire fie screens 3, and volute 5 places suction tude 8 through holes upper end, on volute 5 through-hole surfaces, be connected with 8 oblique guide plates 4 of convex.The friction top 2 that has 6 connecting tendons equally compresses the fie screen 3 that is fixed on support 6 upper ends and the upper end of volute 5 respectively, and the connecting tendon that guarantees frame 1 intracavity bottom respectively with support 6 and friction top 2 on the corresponding coincidence of connecting tendon.During work, filter element is connected in (shown in Figure 3) in the filter case, joins with motor.After ambient air filters by thick, fie screen 7,3 respectively, the swirling eddy that produces of the oblique guide plate of 8 convex in volute 5 through holes 4 again, enter (direction shown in the arrow A among Fig. 3) in the cylinder through suction tude 8, with the abundant mixed combustion of the atomized fuel in the cylinder.
The utility model is applicable to the gasoline of different size model, the air filtering of diesel engine.
