[0002] A compressor is a device used to compress gas or steam into a high-density or high-pressure state. Compressors are often used in the petrochemical industry and are one of the indispensable equipment in industrial production. During the operation of the compressor, the lubricating oil will be carried out by the gas of the compressor and mixed in the exhaust gas. In order to prevent these lubricating oils from entering the equipment or the environment, a lubricating oil exhaust pipe is required to discharge the gas mixed with the lubricating oil.

[0003] When the lubricating oil exhaust pipe is in use, one end is usually connected to the exhaust end of the compressor, and the other end is connected to the intake end of the oil separator. The gas mixed with lubricating oil is discharged into the oil separator through the lubricating oil exhaust pipe, and the lubricating oil is separated from the gas through the oil separator, and the gas is discharged through the oil separator;

[0004] However, in actual use, in order to ensure the use effect of the compressor and increase the service life of the lubricating oil exhaust pipe, it is usually necessary for the staff to regularly clean and maintain the lubricating oil exhaust pipe of the compressor. However, the current lubricating oil exhaust pipe is mostly directly connected to the compressor and the oil separator, and then the lubricating oil exhaust pipe is fixed by a hose clamp. However, since the hose clamp is more troublesome to use, the workers are required to use tools such as bolt cutters to operate during each disassembly and assembly process, which makes it inconvenient for the staff to quickly disassemble and assemble the lubricating oil exhaust pipe of the compressor, thereby reducing the maintenance efficiency of the lubricating oil exhaust pipe.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] Example:

[0031] Reference Figure 1-Figure 9 The utility model embodiment provides a compressor lubricating oil exhaust pipe, including an air pipe body 1, and also includes: two connecting pipes 2, which are respectively connected to the two ends of the air pipe body 1, wherein an elastic sleeve 7 is fixedly installed in the connecting pipe 2, a pipe sleeve 3 is sleeved on the connecting pipe 2, and a positioning plate 4 is fixedly connected to the port of the connecting pipe 2; a plurality of clamping arms 5 are all installed on the positioning plate 4 through elastic members, the number of the clamping arms 5 is 8-12, and the preferred number in this scheme is 8, and they are distributed in an annular shape on the surface of the positioning plate 4, wherein when the clamping arm 5 is subjected to external force, the end of the clamping arm 5 away from the positioning plate 4 deflects toward the axis of the connecting pipe 2, and when the clamping arm 5 is not subjected to external force, the clamping arm 5 is restored to the initial state by the elastic force of the elastic member.

[0032] Specifically, during use, the elastic sleeve 7 can play an anti-slip and sealing role, so that the lubricating oil exhaust pipe can be quickly and tightly connected to the compressor and the oil separator, and by rotating the pipe sleeve 3, the clamping arm 5 is pressed against the exhaust end of the compressor and the intake end of the oil separator, which can facilitate further fixation of the lubricating oil exhaust pipe. By rotating the pipe sleeve 3 in the opposite direction, the pipe sleeve 3 is moved away from the clamping arm 5, so that the exhaust pipe can be quickly released. The lubricating oil exhaust pipe can be used in conjunction with the connecting pipe 2, the pipe sleeve 3, the clamping arm 5, the elastic part and the elastic sleeve 7, so that the staff can quickly disassemble and assemble the lubricating oil exhaust pipe, thereby improving the maintenance efficiency of the lubricating oil exhaust pipe.

[0033] The elastic member includes a straight rod 61 and a rotating sleeve 62. A through groove 6 is opened on the surface of the positioning plate 4. The straight rod 61 is fixedly connected in the through groove 6. The rotating sleeve 62 is rotatably connected to the straight rod 61. A torsion spring 63 is installed between the straight rod 61 and the rotating sleeve 62. The clamping arm 5 is fixedly connected to the rotating sleeve 62.

[0034] Specifically, when the tube sleeve 3 squeezes the clamp arm 5, the end of the clamp arm 5 close to the positioning plate 4 drives the rotating sleeve 62 to rotate and twists and compresses the torsion spring 63. When the tube sleeve 3 moves away from the clamp arm 5, the elastic force of the torsion spring 63 can make the clamp arm 5 rebound to its original position.

[0035] The pipe sleeve 3 is provided with an external thread 8 , the connecting pipe 2 is provided with an internal thread 9 , and the pipe sleeve 3 is threadedly connected to the connecting pipe 2 .

[0036] Specifically, by providing the external thread 8 and the internal thread 9 , it is convenient for a worker to control the movement of the pipe sleeve 3 on the connecting pipe 2 , thereby preventing the pipe sleeve 3 from sliding randomly on the connecting pipe 2 .

[0037] The elastic sleeve 7 is in the shape of a truncated cone and is made of rubber.

[0038] Specifically, such a design allows the exhaust end of the compressor and the intake end of the oil separator to be quickly inserted into the connecting pipe 2, which facilitates the rapid installation of the lubricating oil exhaust pipe.

[0039] A plurality of anti-skid ridges 10 are fixedly connected to the surface of the pipe sleeve 3 . The plurality of anti-skid ridges 10 are arranged in a ring shape on the surface of the pipe sleeve 3 . The number of the anti-skid ridges 10 is 12-18, and 15 is preferred in this solution.

[0040] Specifically, by providing the anti-skid convex strips 10 , the friction force on the surface of the pipe sleeve 3 can be increased, thereby achieving an anti-skid effect.

[0041] The outer wall of the clamp arm 5 is designed to be an inclined surface. When the pipe sleeve 3 moves toward the clamp arm 5, the pipe sleeve 3 slides along the inclined surface of the clamp arm 5 from low to high.

[0042] Specifically, such a design can gradually increase the squeezing force of the pipe sleeve 3 on the clamp arm 5, thereby improving the fixing effect of the clamp arm 5 on the exhaust pipe.

[0043] Working principle: During the use of the compressor lubricating oil exhaust pipe, when installing the lubricating oil exhaust pipe of the compressor, firstly, the two ends of the lubricating oil exhaust pipe are respectively sleeved on the exhaust end of the compressor and the intake end of the oil separator, so that the exhaust end of the compressor and the intake end of the oil separator are both passed through the elastic sleeve 7 and tightly inserted into the connecting pipe 2. The setting of the elastic sleeve 7 can play an anti-skid and sealing role, so that the lubricating oil exhaust pipe can be quickly and tightly connected to the compressor and the oil separator, thereby realizing the quick connection of the lubricating oil exhaust pipe;

[0044] Then, the staff can rotate the pipe sleeve 3, and under the action of the thread, the pipe sleeve 3 moves along the surface of the connecting pipe 2 toward the clamp arm 5, and at the same time slides along the surface of the clamp arm 5 and squeezes it. At this time, the end of the clamp arm 5 close to the positioning plate 4 drives the rotating sleeve 62 to rotate and twists and compresses the torsion spring 63. At the same time, the end of the clamp arm 5 away from the positioning plate 4 deflects toward the axis of the connecting pipe 2 and presses against the exhaust end of the compressor and the intake end of the oil separator, which can facilitate further fixing of the lubricating oil exhaust pipe, improve the stability of its installation connection, and prevent the exhaust pipe from falling off due to excessive impact pressure of the gas mixed with lubricating oil discharged from the compressor;

[0045] Furthermore, when the lubricating oil exhaust pipe of the compressor needs to be disassembled for maintenance, the pipe sleeve 3 can be rotated in the opposite direction to make the pipe sleeve 3 away from the clamping arm 5. Under the elastic force of the torsion spring 63, the clamping arm 5 is deflected and rebounds to the initial position, thereby quickly releasing the hard fixation of the exhaust pipe, and then the lubricating oil exhaust pipe can be directly unplugged from the compressor and the oil separator. The lubricating oil exhaust pipe, through the coordinated use of the connecting pipe 2, the pipe sleeve 3, the clamping arm 5, the torsion spring 63 and the elastic sleeve 7, can facilitate the staff to quickly disassemble and assemble the lubricating oil exhaust pipe, thereby improving the maintenance efficiency of the lubricating oil exhaust pipe.

[0046] 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.
