Embodiment
Below in conjunction with accompanying drawing 1,2,3,4 a kind of embodiment of the present utility model is described.
A kind of novel armored vehicle prefilter, its filter body 10 is the stepped ramp type tubular structure, and its upper diameter is greater than lower diameter.Center support 3 is fixed on the central authorities of filtering body 10 tops by whirlwind wheel 2, and protective housing 6 is fixed on the top of center support 3; Bottom 8 is fixed on the bottom of filter body 10, make and form ring-type dust exhaust port 9 between filter body 10 bottom interior wall and bottom 8 outer rims, outgoing gas connection tube 7 is fixed on the central authorities of bottom 8, the upper end-hole of outgoing gas connection tube 7 is fixed with center bearing bracket 5, be equipped with on the center bearing bracket 5 and scrape husky rotor 1, and scrape the bottom that husky rotor 1 is positioned at filter body 10; Shellproof shell 11 suits of tubular are fixed on the outer wall of filter body 10, and the top of ring-type filter screen 4 links to each other with protective housing 6, and bottom links to each other with the top of the shellproof shell 11 of tubular.
The cyclone blade on the whirlwind wheel 2 and the angle of its axis are 35 °～45 °.The inwall of filter body 10 bottoms is provided with four evenly distributed helical blades 16, and helical blade 16 is positioned at the below of whirlwind wheel 2 and the periphery of scraping husky rotor 1, and makes the lower limb of helical blade 16 be arranged in ring-type dust exhaust port 9.Scraping husky rotor 1 is made up of four big blades 12, four small leaf 13, four connecting rods 14 and runing rest 15; Four big blades 12 are " ten " shape and are fixed on the runing rest 15, four small leaf 13 are fixed on the runing rest 15 by four connecting rods 14 respectively, and four connecting rods 14 are " ten " shape and arrange, make four small leaf 13 lay respectively at the periphery of four big blades 14, the lower end of runing rest 15 is inserted into the central authorities of center bearing bracket 5.
During use, the utility model is vertically mounted on the armored vehicle, and the suction port of fine cleaner on outgoing gas connection tube 7 and the armored vehicle is joined, when the air that contains sand and dust when after filter screen 4 filters, being inhaled under the motor suction function, at first will be through taking turns 2 with whirlwind, because containing the sand and dust air, the effect of whirlwind wheel 2 produces eddy flow, making sand and dust be subjected to stronger centrifugal force filters outside the bodies 10 until discharging by ring-type dust exhaust port 9 along the inwall whereabouts of filter body 10, meanwhile rotational flow air continues descending also making and scrapes husky rotor 11 high speed rotating and produce cyclonic action once more, make sand and dust be subjected to stronger centrifugal force again and filter outside the bodies 10 until discharging, make comparatively clean air enter fine cleaner by outgoing gas connection tube 7 by ring-type dust exhaust port 9 along the inwall whereabouts of filter body 10.
