Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal steam compressors, in particular to a centrifugal steam compressor intake pipe anti-vibration device. Background Art

[0002] A centrifugal compressor is a compressor that relies on the rotation of the impeller and the expansion of the diffuser to do work on the gas, thereby increasing the pressure and velocity of the gas, completing the increase in gas pressure and gas transportation, and the gas flows radially through the impeller.

[0003] When the gas in the pipeline of a centrifugal steam compressor refluxes during operation, the refluxed gas will cause violent vibrations in the compressor body and pipeline. The vibrations will cause the performance of the centrifugal steam compressor to decline, the noise to increase, and the life and safety of the equipment to be affected. Therefore, a centrifugal steam compressor intake pipe vibration proof device is proposed to solve the above problems. Utility Model Content

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0019] Reference Figure 1-5, a centrifugal steam compressor intake pipe shockproof device, including a centrifugal steam compressor, the centrifugal steam compressor includes a centrifugal steam compressor body 1, an intake pipe body 2 and an outlet pipe 3, a gas blocking component is arranged in the intake pipe (the gas blocking component blocks the backflow of the gas with increased air pressure in the outlet pipe 3), the gas blocking component includes a disc 4 fixedly connected to the inner wall of the intake pipe, one end of the disc 4 is provided with a plurality of air holes (the air holes facilitate the flow and discharge of the gas with increased air pressure), a foam plate 7 is arranged above the inner disc 4 of the intake pipe, and a plurality of inserts 8 matched with the air holes are fixedly connected to the bottom end of the foam plate 7 (the inserts 8 match with the air holes so that the inserts 8 can block the air holes, thereby preventing the backflow of the pressurized gas).

[0020] Furthermore, an exhaust hole penetrating the exhaust pipe 3 is provided on the surface of the exhaust pipe 3 (the exhaust hole can discharge the gas that flows back to the foam board 7 and gathers above the foam board 7, thereby avoiding the accumulation of too much pressurized gas above the foam board 7), and an inner wall of the exhaust pipe 3 is provided with an arc-shaped baffle plate 5 that is relatively arranged and fits with the exhaust hole (the arc-shaped baffle plate 5 blocks the exhaust hole, thereby avoiding the leakage of gas when the gas is normally discharged from the exhaust pipe 3), and a limit block 301 that is relatively arranged and in contact with the top of the arc-shaped baffle plate 5 is fixedly connected to the inner wall of the air inlet pipe, and a relatively arranged connecting block 9 is fixedly connected to the surface of the foam board 7, and one end of the connecting block 9 is fixedly connected to the bottom end of the arc-shaped baffle plate 5 (the foam board 7 moves downward and drives the arc-shaped baffle plate 5 to move downward through the connecting plate, thereby separating the arc-shaped baffle plate 5 from the exhaust hole, facilitating the discharge of the refluxed gas).

[0021] It should be noted that the foam board 7 and the disc 4 are connected via an elastic connection assembly, which includes a telescopic rod 6 fixedly connected to the top of the disc 4, one end of the telescopic rod 6 is fixedly connected to the bottom end of the foam board 7, and a reset spring 10 wound around the outer surface of the telescopic rod 6 is fixedly connected between the top of the disc 4 and the bottom end of the foam board 7 (the reset spring 10 and the telescopic rod 6 can reset the foam board 7 pressed down by the gas and block the exhaust hole).

[0022] A further benefit of adopting the above is that the above device prevents the gas in the outlet pipe 3 from flowing back into the centrifugal steam compressor body 1 and the intake pipe body 2, and discharges the refluxed gas, thereby preventing the centrifugal steam compressor body 1 and the intake pipe body 2 from oscillating, thereby avoiding affecting the life and safety of the equipment.

[0023] When the utility model is used: when the centrifugal steam compressor body 1 is needed to pressurize the gas, the staff starts the centrifugal steam compressor body 1, and the high-speed rotation of the impeller in the centrifugal steam compressor body 1 causes the gas to be sucked into the centrifugal steam compressor body 1 from the air inlet pipe body 2, and the gas is pressurized by multiple impellers and diffusers inside, and finally the pressurized gas is discharged through the outlet pipe 3;

[0024] When the centrifugal steam compressor body 1 continuously pressurizes the gas, the gas inside the outlet pipe 3 flows back. Since the gas pressure of the refluxed gas is relatively high at this time, the pressurized gas will push the foam plate 7 downward. The downward movement of the foam plate 7 drives the multiple inserts 8 at the bottom of the foam plate 7 to be pressed downward, and the inserts 8 are inserted into the inside of the air holes on the disc 4 and block the air holes, thereby preventing the gas from flowing back into the centrifugal steam compressor body 1 and the air inlet pipe body 2.

[0025] When the foam plate 7 moves downward, the two arc-shaped baffles 5 are pressed downward through the connecting block 9, so that the arc-shaped baffles 5 are separated from the exhaust holes on the surface of the outlet pipe 3, so that the gas flowing back to the top of the foam plate 7 can be discharged through the exhaust holes, thereby preventing the pressurized gas from accumulating in large quantities above the foam plate 7, thereby preventing the outlet pipe 3 from bursting;

[0026] The above device prevents the gas in the outlet pipe 3 from flowing back into the centrifugal steam compressor body 1 and the intake pipe body 2, and discharges the refluxed gas, thereby preventing the centrifugal steam compressor body 1 and the intake pipe body 2 from oscillating, thereby avoiding affecting the life and safety of the equipment.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
