Abstract
Description
Technical Field
[0001] The utility model relates to a slider type intake guide vane structure with a dust cover, belonging to the technical field of intake guide vanes of air compressors. Background Art
[0002] In many industrial production fields, high-pressure gas is required. To obtain high-pressure gas, a gas compressor needs to be used. Among them, the centrifugal gas compressor has a wide range of gas production pressures, large gas flow rates, and high gas quality, and is an important tool for producing high-pressure gas. However, the intake guide vane structures of current gas compressors mostly drive the driving ring to drive the crank to rotate through a ball joint and a connecting rod. The crank will drive the intake guide vane to rotate, and the opening and closing of the intake pipeline are realized through the rotation of the guide vane, thereby controlling the intake air volume. However, this connecting rod type intake guide vane structure has two disadvantages. One is that there are too many transmission parts and they are easily damaged. The other is that these transmission parts are exposed, and the working environment of the compressor is usually not very clean, and the transmission parts often get stuck due to dust and other reasons.

[0026] Please refer to Figures 1 to 3 , a slider 41 type intake guide vane 20 structure with a dust cover 50 (hereinafter referred to as "slider 41 type intake guide vane 20 structure") shown in an embodiment of the present application. The slider 41 type intake guide vane 20 structure includes an intake duct 10, a drive ring 30, a transmission assembly 40, and a dust cover 50.
[0027] The intake pipe 10 is provided with a number of intake guide vanes 20 penetrating along the radial direction of the intake pipe 10. The number of intake guide vanes 20 are arranged at intervals along the axial direction of the intake pipe 10. By rotating the intake guide vanes 20, a gap is generated between adjacent intake guide vanes 20, thereby opening the intake pipe 10, or by rotating the intake guide vanes 20 so that adjacent intake guide vanes 20 abut against each other to eliminate the gap, thereby closing the intake pipe 10. Therefore, when the intake pipe 10 is set to be closed, the intake guide vane 20 is at 0°, and only by driving the intake guide vane 20 to rotate reciprocally between 0° and 90°, the intake pipe 10 can be closed and opened.
[0028] The driving ring 30 is sleeved on the outer wall of the intake pipe 10 and is located on one side of the outer wall end of the intake guide vane 20 on the intake pipe 10. The driving ring 30 is configured to be reciprocally rotatable relative to the intake pipe 10.
[0029] The transmission assembly 40 is connected between the intake guide vane 20 and the driving ring 30. The transmission assembly 40 includes a connecting rod 31 extending radially outward from the outer wall of the driving ring 30 along the intake pipe 10, a slider 41 formed on the connecting rod 31, and a rocker 42 connected between the slider 41 and the intake guide vane 20. A chute is formed in the length direction of the rocker 42, and the slider 41 is slidably engaged with the chute. By driving the driving ring 30 to rotate, the driving rotating assembly drives the intake guide vane 20 to rotate reciprocally, thereby realizing the opening or closing of the intake pipe 10.
[0030] In this embodiment, the slider 41 is a T-shaped slider 41, and the chute is a convex groove adapted to the shape of the T-shaped slider 41. The rocker 42 is arranged above the connecting rod 31, and the slider 41 is arranged in an inverted T shape, so that the slider 41 is clamped in the convex groove, so that while the slider 41 can slide in the convex groove, the slider 41 is prevented from separating from the convex groove, improving the stability of the connection of the transmission structure.
[0031] In this embodiment, a driving rod 32 is formed on the driving ring 30, and a driving member is connected to the end of the driving rod 32 away from the driving ring 30. The driving rod 32 extends radially outward from the outer wall of the driving ring 30 along the intake pipe 10. By driving the driving member to drive the driving rod 32 to move reciprocally, the driving ring 30 is driven to move reciprocally.
[0032] In this embodiment, a dust cover 50 covers the outside of the transmission assembly 40. Specifically, the dust cover 50 is arranged on the rocker 42 and covers the outside of the transmission assembly 40. The dust cover 50 is in a flat plate shape and covers the outside of all the transmission assemblies 40 to prevent dust from directly falling on the transmission assembly 40.
[0033] In this embodiment, the intake guide vane 20 includes a rotating shaft 21 passing through the intake duct and triangular fan blades disposed within the intake duct 10. The rotating shaft 21 is fixedly connected to the rocker 42. One end of the triangular fan blade connected to the rotating shaft 21 is arc-shaped and adapted to the shape of the inner wall of the intake duct 10. The ends of the triangular fan blades do not abut against each other to facilitate the rotation of the triangular fan blades.
[0034] Please refer to Figure 3 , in this embodiment, the chute includes a head end 421 and a tail end 422. Under the drive of the drive ring 30, the slider 41 reciprocates between the head end 421 and the tail end 422 of the chute to drive the intake guide vane 20 to open or close the intake duct 10. When the slider 41 is on the side close to the head end 421, the rocker 42 is in the first position 60, and the intake guide vane 20 is in a state of completely closing the intake duct 10. The rotation of the drive ring 30 drives the slider 41 to move towards the tail end 422 within the chute, and at the same time drives the rocker 42 towards the second position 70. The intake guide vane 20 gradually opens the intake duct 10. When the rocker 42 moves to the second position 70, the intake guide vane 20 is in a state of completely opening the intake duct 10.
[0035] In this embodiment, the rocker 42 and the rotating shaft 21 are connected by a pin. The pin connection can provide higher tensile and shear strength than ordinary bolt connections, and is particularly suitable for structures that need to withstand large forces or vibrations. At the same time, it is convenient for assembly and disassembly.
[0036] In this embodiment, a sealing seat is provided outside the intake duct 10. The sealing seat surrounds the periphery of the rotating shaft 21. The sealing seat includes an outer housing 11 and a seal 12 disposed within the outer housing 11. The rotating shaft 21 is inserted into the seal 12, and sealing rings are provided between the seal 12 and the outer housing 11 and the rotating shaft 21.
[0037] The beneficial effects of the present utility model are as follows: In this application, a transmission component is provided between the intake guide vane and the drive ring to drive the intake guide vane to rotate so as to close or open the ventilation passage. By using the sliding connection mode of the slider and the rocker, the transmission structure is simpler and more direct, the structure is more stable, and damage to the transmission components is avoided. At the same time, a protective cover is provided outside the transmission component, solving the problem of the transmission components being stuck and damaged due to dust.
[0038] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.
[0039] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
