Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a shock-absorbing oil and gas separation barrel. Background Art

[0002] An oil-injected screw air compressor is a positive-displacement gas compression machine with a rotary working volume. The compression of gas is mainly achieved by the change of volume. The oil and gas separation barrel is a component that separates the coolant of the oil-injected screw air compressor from the compressed air. Since the mixed compressed gas discharged from the air compressor main unit enters the oil and gas separation barrel through a pipeline, the impact of the mixed compressed gas on the inner wall and components of the oil and gas separation barrel during the flow and separation process in the oil and gas separation barrel forms vibrations, resulting in noise. The existing oil and gas separation barrels do not have shock-absorbing and noise-reducing structures, and the impact of the mixed compressed gas on the inner wall and components of the oil and gas separation barrel during the flow and separation process cannot be reduced. In addition, the oil and gas separation barrel needs to be frequently pressurized and depressurized during operation. Over time, the strength of the barrel material is likely to fail, resulting in bursting and causing safety accidents. Therefore, it is necessary to provide a structure that can help reduce the vibration of the oil and gas separation barrel to improve its safety and the stability of the structure setting.

For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection.

[0022] Refer to Figure 1-2 , this embodiment provides a shock-absorbing oil-gas separation barrel, which comprises an outer barrel 11 and an inner barrel 12 arranged in the upper part of the inner cavity of the outer barrel. The outer barrel 11 is a closed pressure vessel, and its external configuration includes an upper cover 111 from top to bottom. The upper cover 111 is mechanically connected to the lower barrel-shaped outer shell 112 to form a sealed outer barrel 11. An exhaust port 111-1 is provided on the upper cover 111. The lower part of the exhaust port 111-1 is connected to the oil separation core 13 in a through manner, and its upper part is connected to the pressure maintaining valve 14.

[0023] A shock-absorbing ring 112-1 is arranged around the outer peripheral wall surface of the barrel-shaped housing 112. Above the shock-absorbing ring 112-2, there is a mixed oil and gas inlet 112-1 extending into the inner barrel 12, and below it, there is an oil return hole 112-3. The shock-absorbing ring 112-2 is arranged at the middle and lower part of the outer barrel wall and is tightly connected to the side wall surface of the outer barrel 11. In this embodiment, by adding a shock-absorbing ring 112-2 made of metal material at the middle and lower part of the outer barrel wall, the structural weight of the oil and gas separation barrel is increased, and the installation center of gravity of the oil and gas separation barrel is further lowered to improve its safety and the stability of the structural arrangement. It can be understood that the gravity generated by the weight of the shock-absorbing ring 112-2 body arranged at the middle and lower part of the outer barrel wall is vertically downward and is superimposed on the gravity generated by the oil and gas separation barrel itself, further pulling the center of gravity of the barrel body downward. The lowering of the center of gravity of the barrel body can effectively improve the force stability of the barrel body and play a role in damping the barrel body. That is to say, when the mixed compressed gas from the mixed oil and gas inlet 112-1 flows and separates in the oil and gas separation barrel, it generates periodic impacts on the wall surface and components of the oil and gas separation barrel, forming vibrations. The vibrations propagating along the barrel body medium will cause the barrel body to shake. The shock-absorbing ring 112-2 adjusts the unsafe phenomenon of the barrel body shaking and structural force instability that may occur after the barrel body is stressed and vibrated by lowering the center of gravity of the barrel body, and improves the balance and stability of the barrel body installation. On the other hand, from the perspective of the connection relationship of the structural configuration, since the shock-absorbing ring 112-2 is arranged on the outer peripheral wall surface of the outer barrel 11 and is tightly connected to the barrel wall of the outer barrel to form a reinforcing rib of the outer barrel body, it can effectively improve the structural strength of the barrel body while lowering the installation center of gravity of the barrel body, and can effectively reduce the irreversible safety accident caused by the failure of the barrel body material strength due to frequent pressurization and pressure relief during the long-term continuous operation of the barrel body, resulting in bursting.

[0024] From the perspective of the detailed structural characteristics, the cross-sectional shape of the shock-absorbing ring 112-2 can be L-shaped, C-shaped or T-shaped, and the connection form of its tight connection with the side wall surface of the outer barrel 11 can be welding or other forms of mechanical connection. If a clamping structure form is used for connection, an elastic ring can be added between the outer peripheral wall surface of the outer barrel 11 and the shock-absorbing ring 112-2. Through the elastic deformation of the elastic ring, an interference connection between components can be achieved. The elastic ring sleeved between the outer peripheral wall surface of the outer barrel 11 and the shock-absorbing ring 112-2 can also play a role in blocking and buffering vibrations.

[0025] An exhaust port 111-1 is provided on the upper cover 111. The lower part of the exhaust port 111-1 is connected to the oil separator core 13 in a through manner, and its upper part is connected to the pressure maintaining valve 14. An oil-gas separation chamber is provided below the oil separator core 13. The oil-gas separation chamber is filled with cooling lubricating oil. A drain port 112-4 is provided at the bottom end of the outer barrel 11 below the cooling lubricating oil, and an oil outlet pipe is inserted into the cooling lubricating oil. The other end of the oil outlet pipe extends and is connected to the oil return hole 112-3 on the side wall of the outer barrel. In addition, an oil filling port 112-5 and an oil viewing mirror 112-6 used in cooperation with the oil filling port 112-5 are installed on the outer side wall of the oil-gas separation chamber. The oil viewing mirror 112-6 is arranged at the same height as the liquid level of the cooling lubricating oil. When the oil-gas separation barrel of the present utility model works, the mixed oil and gas enter the interior of the separation barrel through the mixed oil and gas inlet 112-1 and impact the inner barrel of the separation barrel to achieve preliminary separation of the oil and gas. The separated mixed gas is refined by the oil separator core 13 and then accumulates at the top of the oil-gas separation chamber, and the separated lubricating oil accumulates at the bottom of the oil-gas separation chamber. When a certain pressure is reached inside, the lubricating oil at the bottom is pressed out of the barrel through the oil return hole 112-3. At the same time, the pressure maintaining valve 14 installed at the position of the exhaust port 111-1 is opened to discharge the gas accumulated at the top of the oil-gas separation chamber out of the barrel.

[0026] The above is only the preferred specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any person skilled in the art in the technical field disclosed by the present utility model, making non-substantive modifications to the present utility model using this concept, shall fall within the scope of infringement of the protection scope of the present utility model.
