Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with the specific embodiment of the invention and corresponding accompanying drawing, technical solution of the present invention is clearly and completely described. Obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
According to embodiments of the invention, it is provided that self-cleaning air filter is blown in a kind of pneumatic beating and scattered gas blowout.
Self-cleaning air filter is blown in pneumatic beating and the scattered gas blowout of the present embodiment, including controlling device and winding-up beating dust arrester. Self-cleaning air filter structure chart is blown in pneumatic beating and scattered gas blowout when being illustrated in figure 1 normal air inlet, outside air enters paper filter core from prefilter or upper level filtering unit after primary filter, its small particles and dust are attached to cartridge surface, the air of cleaning enters cleaner, afterwards along with air-flow enters electromotor or next stage filtering unit enters electromotor. This is the route schematic diagram that air filtering crossed by papery cleaner.
Wherein, dust arrester is patted in winding-up, including air pump 1, gas bomb 2, air inlet electromagnetic valve 3, air valve 4, escape pipe 5, annular cylinder liner 6, air inlet pipe 7, clamp nut 8, annular cylinder liner plug 9, beater support 10, return spring 11, gas blow head 12, air relief valve 17, Pressure gauge 18 and valve annular piston 22. Beater support is fixed in filter body 23, and cleaner enclosing cover 16 is fixed on beater support by clamp nut, and filter element enclosing cover 14 need to ensure to contact with filter body 23 to fully seal. Valve annular piston 22 and air valve 4 are integrated part, and in normal air inlet, this integral piece is in open mode under the effect of return spring 11.
When pneumatic beating and scattered gas blowout blow self-cleaning air filter receive blowback air instruction time, air pump 1 produces compression air and reduces to winding-up air pressure needed for system after air relief valve 17. After after gas bomb 2, owing to air inlet pipe 7 caliber changes, at this moment air flow rate is very big, air inlet electromagnetic valve is opened, compression air enters gas blow head 12 through escape pipe 5, current limiting pressure-limiting effect because of gas blow head 12, gas pressure quickly passes back to air inlet pipe 7 from escape pipe 5, when the circular aperture having arrived air inlet pipe 7 end enters into annular cylinder liner, promote valve annular piston 22 and air valve 4 to left movement, return spring 11 is in compressive state, blocks until the filter element 13 of filter body 23 is exported by air valve 4. Gas blow head 12 surface is the aperture of conical ring arrangement, and air-flow, through the scattered gas effect of gas blow head, is uniformly diffused into filter element 13 compressed-air actuated air-flow internal. Now produce pneumatic beating when both of which cleaning filter element: Fig. 2 show back flushing filter core and self-cleaning air filter structure chart is blown in scattered gas blowout.
The first pattern: dissipate gas flow pattern, owing to filter element 13 outlet has the sealing of air valve 4, the chamber pressure making whole " dirty " filter element (filter element such as attaching particles and dust) raises, air-flow can only blow to the cartridge surface of surface attachment granule and dust from inside to outside, reaches the purpose of cleaning filter element;
The second pattern: pneumatic beating pattern, air valve 4 seals outlet, filter element 13 chamber pressure is made to raise, when air pressure be increased to produce the thrust of air valve 4 more than the closing forces of air valve 4 time air valve 4 open, air valve 4 is opened rear filter element 13 chamber pressure and is reduced, with and air valve 4 close, such reciprocation cycle until compression air cleaner filter element after, chamber pressure is reduced to till can not opening air valve. The vibration of patting of air valve 4 is the second pattern cleaning filter element, it is possible to reach the effect of high-efficiency cleaning filter element. It is illustrated in figure 3 pneumatic beating modular system schematic diagram. Granule and the dust of cartridge surface attachment leave cleaner through the dust-exhausting bag of dust-exhausting bag 15, prefilter or upper level filtering unit.
In one example, filter element can select traditional paper filter core or polyester fiber filter element.
In one example, gas receiver provides the compression air of big flow for cleaning filter element, and for this, gas outlet tube all adopts heavy caliber trachea and joint.
In one example, beater support can adopt rear portion trishores mode (such as three-legged support 24) and middle part annular brace mode (such as ring support 25) two kinds, is illustrated in figure 4 two different form of beater support figure.
The control device of the present invention is made up of command switch 20, air inlet electromagnetic valve relay indicating light 21 and accumulator 19, and push button electromagnetic switch selected by switch, and closedown is opened for a long time can to prevent driver from forgetting, increases power consumption to car load accumulator and source of the gas; Additionally, push-button switch can continuous control opening and closing gas circuit, formed pulsed air pressure be conducive to cleaning filter element, also make simultaneously air valve produce pat vibration effect. Air inlet electromagnetic valve relay indicating light lights when air inlet electromagnetic valve works.
The gain effect of the present invention is: technical scheme, the filter element cleaning action of both of which can be realized, remove particulate matter and dust, improve engine aspirating system, the regular maintenance of electromotor and the periodic maintenance of cleaner are played a very good protection, eliminating artificial cleaning and change the tedious work of filter element, operator just can operate in driver's cabin, simply efficiently; Also electromotor has been reached fuel-efficient, the purpose of fuel-economizing, reduce the maintenance cost of vehicle, add benefit. The program relatively simple for structure, it is possible to repacking uses on existing dry type cleaner, debug use, keep in repair more convenient.
Through substantial amounts of verification experimental verification, adopt the technical scheme of the present embodiment, it is possible to save manual maintenance and take and filter element expense.
To sum up, skilled addressee readily understands that, under the premise do not conflicted, above-mentioned each advantageous manner can freely combine, superposition.
The foregoing is only embodiments of the invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations. All within the spirit and principles in the present invention, any amendment of making, equivalent replacement, improvement etc., should be included within scope of the presently claimed invention.
