As shown in Figure 1, in the apex cavity of cover cap interlayer, be provided with the gas tube 9 that ring-type is arranged, gas tube is provided with some blast nozzles 10, and blast nozzle 10 points to initial filter filter core 8, and gas tube 9 is connected by scouring electromagnetic valve 62 with high-pressure air pipe 5.
During use, as shown in Figure 1, after the air-strainer 11 of the bottom of steam outlet pipe 1 and vehicle self is connected and fixed, start vehicle, now be elevated solenoid valve 61, scouring electromagnetic valve 62 is in closedown closed condition, cover cap 2 and cylinder thick stick body are positioned at high point under the effect of spring 34 support force, air hole 22 is opened, now passage 7 is interior in the recent period sucks air, it is inner that air enters into steam outlet pipe 1 through air hole 22 after initial filter filter core 8 filters, then supply engine after air-strainer 11 filters again is entered in air-strainer 11, the particle that air is larger after initial filter filter core 8 is filtered out by initial filter filter core 8 and is trapped in initial filter filter core 8 inside, the air entering into air-strainer 11 is relatively clean, extend the life-span of air-strainer 11, ensure the degree of purity entering into engine interior air.After vehicle stops, open lifting solenoid valve 61, now cylinder is under the effect of pressurized gas, cylinder thick stick body and cover cap 2 glide, after cover cap 2 slides to low spot, air hole 22 is closed, now open scouring electromagnetic valve 62, pressurized gas to be sprayed by blast nozzle 10 through gas tube 9 and clean initial filter filter core 8, residual particles in initial filter filter core 8 is rinsed out, rinse complete, close scouring electromagnetic valve 62, lifting solenoid valve 61, now cover cap 2 slides lofty perch again under the support force effect of spring 34, air hole 22 is opened, for the startup of vehicle is next time ready.
As shown in Figure 1, be provided with position limit switch 12 at cover cap 2 inner top, when cover cap 2 slips down to low spot, position limit switch 12 is triggered and sends signal.During manufacture, controller can be set in the operator cabin of vehicle, position limit switch 12, lifting solenoid valve 61, scouring electromagnetic valve 62 be electrically connected with controller, realize automatically controlling.Because the control principle of this controller is comparatively simple, be not described in detail in this manual.
Embodiment 2
Because the environment of vehicle operation varies, when vehicle operation is under high dust rugged environment, as under the occasions such as desert, colliery, building site, also larger particle is had to be sucked in air-strainer unavoidably even if air carries out initial filter, for solving this technical problem, the present embodiment has done further improvement on the basis of embodiment's 1 generator.
As shown in Figure 2, in the present embodiment, oil filter device is provided with in the below of the steam outlet pipe 1 of embodiment's 1 generator, this oil filter device comprises an accumulator 13, the top of accumulator be connected with steam outlet pipe 1 end and the inner chamber of accumulator 13 and steam outlet pipe 1 through, in accumulator, be provided with secondary steam outlet pipe 14, this secondary steam outlet pipe 14 bottom is through the base plate of accumulator 13, and the top of secondary steam outlet pipe 14 is positioned at accumulator inside.
As shown in Figure 2, also comprise an air conducting cover 15, this air conducting cover 15 covers on the top of secondary steam outlet pipe 14, air passageways 16 is left between the top of air conducting cover 15 and secondary steam outlet pipe 14, be connected and fixed by hiding food tray 17 between the bottom of air conducting cover 15 and the tube wall of secondary steam outlet pipe 14, this screening food tray 17 is ring-type, hides food tray and is provided with some through holes, between air conducting cover and the tube wall of secondary steam outlet pipe, be provided with oil filter filter core 18, oil filter filter core 18 is positioned at and hides above food tray 17.
Known shown in 2 with reference to the accompanying drawings, when this device uses, air-strainer 11 and secondary steam outlet pipe 14 are connected and fixed, air is after initial filter filter core 8 filters, air enters in accumulator 13, after air conducting cover 15 water conservancy diversion, air is first by the lateral current downflow of air conducting cover 15, formed to stir to the filter oil bottom accumulator 13 and impact, granule foreign large in air is after oil strain absorption, it is inner that air enters into air conducting cover 15, enters in secondary steam outlet pipe 14 and air-strainer 11 after oil filter filter core 18 filters through air passageways 16.
Arranging between the bottom of air conducting cover 15 and the tube wall of secondary steam outlet pipe 14 and hiding food tray 17 is prevent from air from forming larger impact to filter oil cause filter oil to splash thus cause oil to filter filter core oil suction and too much lose airfiltering effect, comparatively damp state can be remained by arranging screening food tray 17 oil filter filter core 18, neither affect passing through of air, also can strengthen the adsorption effect to particle simultaneously.
After adopting said apparatus, the Environmental Conditions of vehicle is greatly expanded, work under high concentrate dust environmental conditions in time and also can ensure to be drawn into the degree of purity of engine interior air, ensure that the service behaviour of motor, and at any time initial filter filter core is cleaned, avoid and need people to be the Operating Complexity of disassembly, cleaning, extend the working life of filter core.
