Abstract
The invention relates to a series connection type air filter to mainly solve the problems that dust enters an engine due to inappropriate maintenance of the existing air filter and accordingly the engine is abraded and the like. According to the technical scheme of the series connection type air filter, an upper cover is arranged on one side of a cylinder; a flange is arranged on the other side of the cylinder; an air inlet is arranged at the circumference of the cylinder; a dust discharging valve is arranged at the lower end of the cylinder. The series connection type air filter is characterized in that the cylinder is separated by a grating flange to form into a fist cylinder chamber and a second cylinder chamber; a first main filter element is arranged inside the first cylinder chamber; a second main filter element is arranged inside the second cylinder chamber; the first main filter element and the second main filter element are in series connection through the grating flange. The series connection type air filter has the advantages of effectively preventing the air filter service life from reducing and dust entering the engine due to inappropriate maintenance and reducing costs and space for using two sets of air filters.
Description
Technical field
The present invention relates to a kind of tandem air-strainer, effectively can improve the dust discharge efficiency of air-strainer, conserve space, and then the working life of improving whole air-strainer; In addition, this invention, for incorrect maintenance, causes dust to enter air filter steam outlet pipe and directly enters motor, can effectively solve.
Background technique
At present, known air-strainer working principle is with reference to figure 1, upper cover 11 is arranged on cylindrical shell 1 side, flange 9 is arranged on cylindrical shell 1 opposite side, suction port 2 is arranged on cylindrical shell border, dust discharge valve 10 is arranged on cylindrical shell 1 lower end, unclean air enters air-strainer inside by air-strainer suction port 2, when unclean air is through spinning disk 3, motion state and mode change, be spiral motion by translate linear motion, under the left and right of centrifugal force, the dust that in unclean air, quality is larger or impurity are separated, and be piled up in the dust discharge valve 10 of air-strainer rear end, then by the filtration of main filter core and safety filter element, motor is entered from air outlet.Unclean air enters air filter cylindrical shell 1 from suction port 2, produces centrifugal force part dust is isolated cylindrical shell from dust discharge valve 10 under the guiding of spinning disk, and then is filtered by main filter core safety filter element, and cleaned air will enter motor from air outlet.But in the very large situation of dust environment, air filter core accumulates dust speed quickly, the increase of filter core flow resistance causes filter core blocking, the negative pressure increase in air filter cylindrical shell quickly, causes engine charge not enough.Now main filter core usually can remove and maintain by people, when dismounting filter core, frequent and inappropriate maintenance dismounting can cause coming off of safety filter element, makes dust directly enter motor, causes the life-span of motor to reduce further.Also there is client that two air filters are installed on car load, considerably increase cost like this, also result in the increase of air filter placement space.
Summary of the invention
The object of this invention is to provide a kind of tandem air-strainer, mainly solve the problems such as working life that existing air-strainer causes due to performance degradation after incorrect maintenance etc. is low; Simultaneously by improving internal structure, unclean air, impurity or moisture is avoided directly to enter the problem of motor.
The technical solution adopted for the present invention to solve the technical problems is: tandem air-strainer, upper cover is arranged on cylindrical shell side, flange is arranged on cylindrical shell opposite side, suction port is arranged on cylindrical shell border, dust discharge valve is arranged on cylindrical shell lower end, it is characterized in that described cylindrical shell is separated by grid flange and form 1# cylindrical shell chamber and 2# cylindrical shell chamber, in 1# cylinder chamber indoor, the main filter core of 1# is set, in 2# cylinder chamber indoor, the main filter core of 2# is set, the main filter core of 1# and the main filter core of 2# are contacted by grid flange, and spinning disk is set at 1# cylindrical shell chamber, Bracket setting is in cylindrical shell in 2# cylinder chamber chamber interior walls, support the main filter core of 2#.
The invention has the beneficial effects as follows, only can dismantle 1# main filter core during maintenance and maintain, prevent and treat inappropriate dismounting and safety filter element is come off and the motor caused enters ash, the engine scuffing caused.Tandem air filter effectively reduces cost and the spatial requirement that air-strainer is overlapped in use two.
Accompanying drawing explanation
Fig. 1 is existing air-strainer fundamental diagram.
Fig. 2 is structural representation of the present invention.
Fig. 3 is fundamental diagram of the present invention.
In figure: 1-cylindrical shell, 2-suction port, 3-spinning disk, 4-1# cylindrical shell chamber, the main filter core of 5-1#, 6-grid flange, the main filter core of 7-2#, 8-2# cylindrical shell chamber, 9-flange, 10-dust discharge valve, 11-upper cover, 12-support, 13-seal ring.
Embodiment
With reference to Fig. 2, 3, tandem air-strainer, comprise cylindrical shell 1, suction port 2, dust exhaust port 10, upper cover 11, the main filter core 5 of 1#, the main filter core of 2#, spinning disk 3, grid flange 6, seal ring 13, flange 9 air outlet and support 12, suction port 2 is arranged on cylindrical shell 1 border, upper cover 11 is arranged on cylindrical shell 1 side, flange 9 is arranged on cylindrical shell 1 opposite side, dust discharge valve 10 is arranged on cylindrical shell 1 lower end, described cylindrical shell is separated by grid flange 6 and forms two chambers, grid flange 6 can be taken out from upper cover 11 side, the main filter core 5 of 1# is set in 1# cylindrical shell chamber 4, the main filter core 7 of 2# is set in 2# cylindrical shell chamber 8, the main filter core of 1# 5 and the main filter core 7 of 2# are contacted by grid flange 6, and spinning disk 3 is set at 1# cylindrical shell chamber 4, support 12 is arranged in cylindrical shell 1 and 2# cylindrical shell chamber 8 inwall supports the main filter core 7 of 2#.
When motor is in operation, dirty air enters in cylindrical shell 1 from suction port 2, led after eddy flow by spinning disk 3 and arrive 1# cylindrical shell chamber 4, dust, impurity or the moisture etc. in a part of air are filtered, then air arrives 2# cylindrical shell chamber 8 from main filter core 5 inside of 1# by the grate opening of grid flange 6 after 1# main filter core 5 second time is filtered, filter through the third time of the main filter core 7 of 2# again, finally export clean air from flange 9, dust, impurity or moisture etc. simultaneously in air cannot enter engine interior.
Grid flange 6 is fixed in cylindrical shell 1 by screw and seal ring 13, by completely isolated for cylindrical shell two chambers, take out, facilitate the main filter core of client's dismounting 2# after can unloading screw from upper cover 11 side.The clean air that can will filter through the main filter core 5 of 1#, in grid guiding 2# cylindrical shell chamber 8, then filter through the main filter core 7 of 2#, final air enters motor by air outlet flange 9.Its side of grid flange 6 is fixed on the opening of the main filter core 5 of 1#, for sealing main filter core, prevents not cleaned air from directly entering in 2# cylindrical shell chamber 8 by grid flange 6, and its opposite side is used for the fixing main filter core 7 of 2#, prevents its rocking in running.
Support 12 is arranged in cylindrical shell 1 on 2# cylindrical shell chamber 8, plays leading role, and give the main filter core 7 of 2# when air filter long-term work with supporting effect when installing the main filter core 7 of 2#.
