Abstract

The utility model relates to a cyclone type air filter which comprises a sediment bowl, an air inlet pipe, a filter barrel chamber and an air delivery pipe, wherein the air inlet pipe between the sediment bowl and the filter barrel chamber is inserted with a cyclone separating device, or the cyclone separating device is directly arranged in the upper half part of the filter barrel chamber; the cyclone separating device comprises a casing, a flow-guiding cover, a wind baffling sheet and a dust outlet; the flow-guiding cover is conic, is fixed at the top end at the lower half part of the air inlet pipe by three upright posts, and remains gaps with the casing, and the upper and the lower parts of the air inlet pipe; the wind baffling sheet forms a circular arc shape, and is fixed on a conic external bevel of the flow-guiding cover; the bottom part of the casing is conic, and is connected with the dust outlet in a tangential direction. Dust particles in the air are exhausted from the dust outlet under the guide of the flow-guiding cover, the air enters the filter barrel chamber through the lower half part of the air inlet pipe from the lower part of the flow-guiding cover for secondary filtration so as to ensure the normal work of the air filter and extend the service life of the air filter.

Description

A kind of rotary flow type air-strainer

A kind of rotary flow type air-strainer of technical field belongs to the composite set field of separating solid particles from gas, relates in particular to a kind of air-strainer of using free cyclone device.

The existing combustion air cleaner of background technique carries out air-filtering by separating shaft screen and nonwovens, and under the work condition environment that stirs up a cloud of dust in farmland etc., the ubiquity filtration resistance is bigger, stops up easily, even causes faults such as internal-combustion engine stops working.

Summary of the invention the utility model is a kind of rotary flow type air-strainer, the air-strainer of forming the airfiltering duplex of two-stage by a cyclone separation device and original air-strainer, it comprises sediment bowl, suction tude, filter cartridge chamber and pneumatic tube, on the suction tude between sediment bowl and the filter cartridge chamber, a peg graft cyclone separation device or cyclone separation device directly is built in the first half in filter cartridge chamber, cyclone separation device comprises housing, air guide sleeve, wind-retarding plate and dust-discharging mouth, air guide sleeve is conical, place the housing middle part, be fixed on the top of suction tude Lower Half by 3 root posts, and be the axle center with the suction tude, on housing and suction tude, the gap is left in the bottom, wind-retarding plate is fixed on the outer inclined-plane of air guide sleeve taper shape, wind-retarding plate is a circular arc, one end and suction tude external diameter are tangent, the other end and air guide sleeve outer rim intersect, 3 wind-retarding plates of 1 are equidistantly arranged on the inclined-plane outside the air guide sleeve taper shape, housing bottom is conical, be connected to the dust-discharging mouth at the housing bottom tangent direction, air enters cyclone separation device by sediment bowl and suction tude, bigger dust particle is under the guiding of air guide sleeve, be thrown toward the sidewall of cyclone separation device, and bottom being deposited to, discharge from the dust-discharging mouth, clean air enters the filter cartridge chamber from the air guide sleeve below by the suction tude Lower Half, carry out secondary filter again, thereby guarantee that filter cleaner can proper functioning, prolonged the service time of filter cleaner.

Description of drawings Fig. 1 is peg graft on the suction tude between sediment bowl and the filter cartridge chamber structural representation of a cyclone separation device of the utility model;

Fig. 2 is the structural representation that the utility model directly is built in cyclone separation device the filter cartridge chamber first half;

Fig. 3 is the structural representation that the utility model wind-retarding plate distributes on air guide sleeve;
