Abstract
The invention relates to a self-cleaning air filter comprising a box. The filter is characterized in that the box is fixed on a support; a gas inlet port is provided on the bottom of the box body; a rough filtering box is arranged at the gas inlet port on the bottom of the box body; a through hole is provided between a box a and a box b; a high-efficiency filtering cylinder is arranged on the through hole on the side of the box b; a venturi tube is provided on the through hole on the side of the box a; the venturi tube is connected to a purifying chamber; the purifying chamber is provided with a clean gas outlet on the side of the box a; a compressed air inlet is arranged on the bottom of the box b; the compressed air inlet is connected with a gas back flushing nozzle arranged on an end of the venturi tube beyond the through hole; a sealing ring b is provided between the high-efficiency filtering cylinder and the through hole. The filter provided by the invention has the advantages that: two layers of filtering devices are provided, such that the filtering effect of the filter is improved, and air can be better purified; a sealing plane is added in the connection part, such that air short-circuit is avoided, and a filtering effect is enhanced.
Description
Technical field
The present invention relates to art of filters, relate in particular to a kind of self-cleaning air filter.
Background technology
Air cleaner refers to air filter, generally is used for dust proof workshop, clean room, and laboratory and toilet perhaps are used for the dustproof of electric mechanical communication equipment etc.Air cleaner uses comparatively general, particularly on Agricultural automotive vehicle and the long-distance bus, air is filtered, thereby avoids entering cylinder with the air of particle, and there is infringement in machine.Air cleaner effect of the prior art is bad, because the sealing surface of filter element is few, has the air short circuit phenomenon simultaneously, is difficult to play a role in filtering.Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this invention is to provide a kind of self-cleaning air filter.
The technical solution used in the present invention is:
A kind of self-cleaning air filter, comprise casing, described casing is fixed on the support, described bottom half is provided with air intake, described bottom half air intake place is provided with the coarse filtration case, described casing comprises casing a and casing b, described casing a is located at casing b top, be provided with through hole between described casing a and the casing b, be positioned at casing b side on the described through hole and be provided with the high efficiency filter cylinder, be positioned at casing a side on the described through hole and be provided with Venturi tube, described Venturi tube connects the clean room, described clean room places casing a one side to establish the pure qi (oxygen) outlet, and described casing b bottom is provided with the compressed air inlet, and described compressed air inlet is connected at Venturi tube away from the blowback air nozzle of through hole end.
Be provided with sealing ring b between described high efficiency filter cylinder and the through hole, be provided with sealing ring a between described Venturi tube and the through hole.
Be provided with the negative pressure probe in the described casing a, described negative pressure probe connects the control display device.
Advantage of the present invention is: be provided with two-layer filter element, improve the filter effect of filter, reach better and purify air, increase sealing surface in the attaching parts, avoided the air short circuit, strengthen filter effect.
