Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-2, a screw air compressor comprises a housing 1, a screw air compressor main body 2 is installed inside the housing 1, specifically, the screw air compressor main body 2 is detachably installed with the housing 1 through bolts and a base, an air inlet 11 is formed in one side of the housing 1, specifically, the air inlet 11 is located inside the housing 1, the air inlet 11 plays a role in air suction work of the screw air compressor on one hand and facilitates air flow circulation on the other hand, cooling oil, a motor and the whole housing 1 are cooled, an air inlet plate 3 is fixedly connected to the surface of the housing 1 at the position of the air inlet 11, two parallel-distributed filter screens 4 are arranged inside the air inlet plate 3, specifically, the filter screens 4 are fixedly connected with the air inlet plate 3, the filter screens 4 further filter air, a brush frame 7 is sleeved on the surface of each filter screen 4, specifically, the brush frame 7 is in surface contact, brush frame 7 comprises for fixed frame and inside brush hair, and the brush hair is fixed on the inner wall of fixed frame, and two spouts 5 that are parallel distribution are seted up on the surface of air inlet plate 3, and the equal sliding connection in inside of every spout 5 has slider 6, through connecting block 8 fixed connection between slider 6 and the brush frame 7, and is specific, slider 6 and connecting block 8's side fixed connection, brush frame 7 and connecting block 8's positive fixed connection.

The scheme has the following working processes:

screw compressor machine is at the during operation, the motor rotates, screw compressor machine begins to breathe in, outside gas gets into from air intake 11, gas gets into screw compressor machine's inside, gas is discharged after being compressed, when gas passes through air inlet plate 3's filter screen 4, filter screen 4 filters the dust in the gas, after filter screen 4 uses for a long time, filter screen 4's surface forms thicker dust, the slider 6 of pulling both sides this moment, slider 6 slides from spout 5 insidely, slider 6 drives the motion of connecting block 8, two connecting blocks 8 drive brush frame 7 at the surperficial slip of filter screen 4, brush frame 7 clears up the dust on filter screen 4 surface, filter screen 4 can continue to use, continue to filter.

According to the working process, the following steps are known:

carry out the prefilter through filter screen 4 to the air that gets into casing 1 inside, rethread brush frame 7 cleans filter screen 4, for among the prior art, at screw air compressor machine during operation, the air is direct when getting into casing 1 inside from casing 1's fresh air inlet, because external air carries more dust, cause the inside motor element of casing 1 to receive the cover of dust on the one hand, cause the reduction of component life, on the other hand screw air compressor machine's the direct filtration air of filter core, the life of filter core is limited, the filter screen 4 of this scheme can reduce piling up of the inside dust of casing 1 on the one hand, prolong inside electronic component's life, on the other hand filter core filters the dust volume and reduces, prolong the life of filter core.

Further, collecting vat 9 has been seted up to air inlet plate 3's inside, and collecting vat 9 and spout 5 intercommunication, and is concrete, and collecting vat 9 plays the effect of collecting the dust, makes things convenient for the dust that filter screen 4 surface cleaning got off to collect more.

Further, the bottom inner wall sliding connection of collecting vat 9 has slide 10, and is concrete, and slide 10 inside collecting vat 9 can directly be taken out from collecting vat 9, makes things convenient for pouring out of dust more after the dust is collected.

Further, the top of slide 10 is equipped with baffle 14, and baffle 14 inclines to central point department along slide 10 width direction, and is concrete, and baffle 14 can be when the dust descends, to the dust guide effect, makes things convenient for the collection of dust more on the one hand, and on the other hand baffle 14 can block the motion of slider 6, and then makes things convenient for slider 6 to move the back and upwards promote and reset.

Further, spout 5 still includes straight section 12 and spacing section 13, and spacing section 13 is located the top of straight section 12, and spacing section 13 is "splayed", and is concrete, and slider 6 slides in straight section 12, and when spacing section 13, the top card of slider 6 is in spacing section 13, and whole slider 6 must be fixed a position, makes things convenient for the resetting of slider 6 after the slip more.

Further, the both sides of slider 6 all are equipped with the chamfer, and is concrete, and slider 6 slides in spout 5, and slider 6's chamfer reduces the collision of slider 6 with 5 inner walls of spout, further makes things convenient for slider 6's slip.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
