Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
referring to fig. 1-4, the novel diesel engine air filter assembly comprises an air filter body, the air filter body comprises an air filter lower shell 1, an air filter air guide body 2 is fixedly connected in the air filter lower shell 1, an air inlet pipe penetrating through the air filter air guide body 2 is fixedly connected in the air filter lower shell 1, the air filter air guide body 2 comprises a support ring 3, a support body 4 is fixedly arranged in the middle of the support ring 3, a filter element is connected to the support body 4, a plurality of air inlet channels are further formed in the support ring 3, a plurality of air inlet holes 6 are formed in the support body 4, a cyclone filter cup 7 is further fixedly arranged at the top of the support ring 3, a guide ring 8 is arranged on the inner wall of the cyclone filter cup 7, the guide ring 8 inclines towards the direction of the air inlet pipe, a cyclone body cover 9 is fixedly arranged on the cyclone filter cup 7, and dust exhaust holes 10 are formed in the outer wall of the cyclone filter cup 7.
When the air filter assembly is used, the air filter assembly is connected to an engine, when the engine starts to work, air enters from the air filter and then passes through the air guide body 2 of the air filter, the air enters along with the air inlet channel due to the air inlet channel arranged on the air guide body, at the moment, the air can strike the guide ring 8 due to the fact that the guide ring 8 is arranged on the inner wall of the cyclone filter cup 7, larger and heavier particle impurities in the air can drop downwards and are discharged from the air inlet channel, the other part of lighter dust impurities can be guided to perform rotary motion under the guidance of the guide ring 8, meanwhile, the distance between the guide ring 8 and the air inlet pipe is gradually reduced due to the fact that the guide ring 8 is inclined towards the direction of the air inlet pipe, the flowing speed of the air is gradually accelerated, the dust impurities in the air are thrown outwards due to the fact that the dust discharge holes 10 are formed in the outer wall of the cyclone filter cup 7, the dust is directly discharged from the dust discharge holes 10, the service life of the filter element is effectively prolonged, and the replacement frequency of the filter element is reduced.
Further, the air inlet channels are uniformly distributed on the bracket ring 3 and are inclined. Since the air inlet passage is inclined, when air enters through the air inlet passage, the direction thereof is guided by the air inlet passage to be inclined, and when the air impinges on the guide ring 8, rotation occurs more easily.
Further, the top of the guide ring 8 is higher than the top of the cyclone filter bowl 7. Since the top of the guide ring 8 is higher than the top of the cyclone filter cup 7, when air just enters the air filter wind guide body 2, the particulate impurities with larger gravity will strike the guide ring 8 with higher probability, so that sedimentation directly occurs.
Further, the outer air inlet pipe 11 and the air inlet pipe are separately arranged and are welded and connected below the air inlet pipe. Because the outer air inlet pipe 11 is close to the engine, the working environment is more severe, high-temperature-resistant metal is needed, if the outer air inlet pipe 11 and the air inlet pipe are integrally formed, the same material is needed, the cost is high, the air inlet pipe and the outer air inlet pipe 11 are arranged in a split mode, and the outer air inlet pipe 11 is directly welded and connected below the air inlet pipe, so that the cost is effectively reduced.
Further, an outer air inlet pipe 11 is fixedly connected below the air inlet pipe, the top of the air inlet pipe penetrates through the cyclone body cover 9 and exceeds the upper surface of the cyclone body cover, the top of the air inlet pipe is connected with a sealing piece, the top of the air inlet pipe is provided with a threaded portion 12, and the sealing piece is a nut 13 and is connected to the threaded portion 12 in a sealing mode through the nut 13. Through this kind of structure, under the state of extreme low temperature, if diesel engine can't normally start, can pour into a few drops of engine oil into in the intake pipe, can effectually assist diesel engine's start-up, because the intake pipe is surpassing whirlwind body lid 9, so can be more accurate when pouring into engine oil, can not take place the skew.
