Description
Technical field
The utility model relates to a kind of air-strainer, particularly a kind of desert double-stage air cleaner assembly.
Background technique
Air-strainer is arranged in engine aspirating system, the assembly that it is made up of the filter component of one or several clean air.It mainly acts on is that filtering will get into objectionable impurities in the air of cylinder, to reduce the premature wear of cylinder, piston, piston ring, valve and valve seat.The desert air-strainer is applicable to that the vehicle of work under the bigger environment of dust uses.At present, the air-strainer that generally uses is as shown in Figure 5, and the fine cleaner that this air-strainer is made up of safe filter core made of paper and main filter core constitutes; Air only filters through one-level, and its air-flow guiding is that air directly gets into the papery filter core, yet when relatively poor environmental work; Air can be brought a lot of impurity into and get into, and dust that carries in the air and moisture can't separate, and directly are adsorbed on the papery filter core; Therefore the air filter efficiency that imports motor is low; Accelerated the wearing and tearing of motor, and impurity easy blocking papery filter core, the working life of reducing air-strainer.
Summary of the invention
The technical problem that the utility model will solve is: provide a kind of and through strainer and fine cleaner the engine operation required air has been carried out double-stage filtering; Filter efficiency is high; The desert double-stage air cleaner assembly of long service life has solved the problem that exists in the above-mentioned existing technology.
The technological scheme that solves the problems of the technologies described above is: a kind of desert double-stage air cleaner assembly, comprise fine cleaner and strainer, and fine cleaner and strainer connect into overall structure; The suction port UNICOM of the air outlet of strainer and fine cleaner; Described fine cleaner comprises the fine cleaner housing, is installed in the main filter core in the fine cleaner housing and is sleeved on the safe filter core formation in the main filter core that described strainer is made up of strainer housing and whirlwind fluid director, has air inlet on the described strainer housing; Have the clean air air outlet on the fine cleaner housing; Described whirlwind fluid director is to be made up of the whirlwind honeycomb duct, and described whirlwind honeycomb duct is made up of outer tube and center tube, and the bottom of center tube is provided with cyclone blade; The cyclone blade of center tube partly is sleeved in the outer tube; Center tube outer wall and outer tube wall form the space, and described strainer housing bottom is connected with the end cap with dust collecting structure, and end cap is provided with dust-exhausting bag.
The space that described center tube outer wall and outer tube wall form is 4～6mm.
The vertical layout of whirlwind fluid director of the main filter core of described fine cleaner and strainer.
The utility model is the double-stage air cleaner structure that is made up of strainer and fine cleaner; The whirlwind fluid director of strainer is to be made up of some whirlwind honeycomb ducts; Described whirlwind honeycomb duct is made up of outer tube and center tube; The bottom of center tube is provided with cyclone blade, and the cyclone blade of center tube partly is sleeved in the outer tube, makes center tube outer wall and outer tube wall form the space.After band dirt air gets into strainer by air inlet; The dust and the fine grains of sand rotate into the whirlwind fluid director by cyclone blade with the wind, and dust and fine sand grain get into collection tray than heavy through the whirlwind fluid director; Because air ratio heavy and light; Therefore air gets into fine cleaner by the center tube of whirlwind fluid director, and the dust and the fine grains of sand deposit in the end cap with dust collecting structure, and external from dust-exhausting bag discharge double-stage air cleaner assembly.After half clean air that coarse filtration is crossed gets into fine cleaner; Papery master's filter core through fine cleaner filters (secondary filter) again; Filter again through papery safety filter core again; Can obtain cleaner pure air (the utility model working procedure is referring to Fig. 4), this moment, purer air got into motor, and is greatly enhanced the working life of motor.
In sum, the utility model has carried out double-stage filtering through strainer and fine cleaner to the engine operation required air; Dust to carrying in the air has carried out the cyclonic separation control of dust; Dust discharge, filter efficiency is high, and because the filtration of strainer is arranged; The filter paper made of paper of fine cleaner is difficult for being stopped up by impurity, has prolonged the working life of air-strainer.
Below, in conjunction with accompanying drawing and embodiment the technical characteristics of the desert double-stage air cleaner assembly of the utility model is further described.
