Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-5, the present utility model provides a technical solution: a three-lobe Roots blower with filtering capability, comprising: the fan comprises a fan main body 1, a motor 2, an air outlet pipe 3, an air inlet pipe 4, a filter screen 5, a connecting cylinder 6 and a connecting rod 7, wherein the fan main body 1 is connected with the motor 2 through a belt, the air outlet pipe 3 is connected to the outer side of the fan main body 1, the air inlet pipe 4 is installed at the top of the fan main body 1, the filter screen 5 is installed in the inner part of the air inlet pipe 4, the connecting cylinder 6 is arranged at the top end of the filter screen 5, the connecting rod 7 is welded on the outer side of the connecting cylinder 6, a cover plate 8 is arranged at the top end of the connecting cylinder 6, an air inlet 9 is internally penetrated and arranged, a rotating block 10 is welded on one side of the cover plate 8, a clamping block 11 is welded on the other side of the cover plate 8, a fixed block 12 is welded on one end, close to the outer side of the connecting cylinder 6, a U-shaped groove 13 is internally provided with a limiting block 14, a rotating structure is formed between the cover plate 8 and the connecting rod 7 through the rotating block 10, and a clamping block 14 is formed between the clamping block 11 and the fixed block 12.

During the concrete implementation, can keep fairly tiny clearance with the inner wall of fan main part 1 when the inside impeller of three leaf roots blower rotates, each other do not contact between them, filter screen 5 filters the clearance that needs to take out after a certain time to the air, traditional mode of taking out is comparatively troublesome, can stimulate fixture block 11 to remove for this reason, can extrude stopper 14 when fixture block 11 removes, because stopper 14 is the rubber material, stopper 14 can produce deformation when receiving the extrusion, can drive apron 8 when simultaneously the fixture block 11 removes and remove, can drive the turning block 10 when apron 8 removes and remove, can rotate through connecting rod 7 when turning block 10 removes, can directly pull filter screen 5 when fixture block 11 completely follow the inside roll-off of U type groove 13 and apron 8 completely removes from the connecting cylinder 6 top, thereby can take out filter screen 5 fast and clear up, and save time.

Referring to fig. 1, 2, 3 and 4, it can be seen that the three-blade Roots blower can quickly take out and clean the filter screen 5 during use.

Referring to fig. 1, 2 and 5, it can be seen that a connecting block 15 is welded at the bottom of the air outlet pipe 3, a threaded rod 16 is movably connected inside the connecting block 15, an anti-slip base 17 is welded at the bottom of the threaded rod 16, a rotating groove 18 is formed inside the connecting block 15, a threaded ring 19 is connected to the outer side of the threaded rod 16, a T-shaped block 20 is connected between the threaded ring 19 and the rotating groove 18, and a rotating structure is formed between the T-shaped block 20 and the connecting block 15 through the rotating groove 18.

During the concrete implementation, three leaf roots air-blower can inhale the inside of fan main part 1 through air-supply line 4 with external air to discharge through air-supply line 3, air-supply line 3 size is longer generally, and do not have the supporting measure, easily lead to air-supply line 3 to produce when fan main part 1 and motor 2 are operated simultaneously and rock, stability is not high, can rotate screwed ring 19 for this reason, can drive T type piece 20 and rotate when screwed ring 19 rotates, T type piece 20 can rotate through rotary groove 18, and screwed ring 19 can carry out the screw sliding with threaded rod 16 when rotating, can drive anti-skidding base 17 when threaded rod 16 screw sliding, can stop rotating screwed ring 19 when anti-skidding base 17 bottom moves to ground surface, anti-skidding base 17 and threaded rod 16 can carry out auxiliary stay to air-supply line 3 this moment, thereby can improve the stability degree of air-supply line 3.

Referring to fig. 1, 2 and 5, it can be seen that the stability of the air outlet pipe 3 can be improved by the anti-slip base 17 and the threaded rod 16 during the use of the three-blade Roots blower.

In summary, when the three-blade Roots blower with the filtering function is used, the blower main body 1 internally comprises two impellers, the two impellers are identical, and three blades on each impeller are identical, the two impellers rotate in opposite directions, as the gaps between the impellers and the impellers, the impellers and the shell, and between the impellers and the wallboard are extremely small, so that the air inlet forms a vacuum state, air enters the air inlet cavity under the action of atmospheric pressure, then, two of the two impellers, the wallboard and the shell form a sealing cavity in each impeller, the air in the air inlet cavity is continuously brought to the exhaust cavity by the sealing cavity formed by the two blades in the rotating process of the impellers, and the impellers in the exhaust cavity are meshed with each other, so that the air between the two blades is extruded out, and thus the three-blade Roots blower continuously runs, and the air is continuously conveyed from the air inlet pipe 4 to the air outlet pipe 3.

Although the present utility model has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present utility model.
