The housing 1 comprises a first cylindrical part 12, a second cylindrical part 11 and a conical part 13, and the assembly of the housing 1 is simple and convenient, and the installation of components such as a filter component, a partition component 4 and the like is also convenient. The three parts of the shell 1 are detachably connected or welded into a whole.
In another embodiment, as shown in fig. 1 to 6, the first separation area 6 is distributed up and down along the axial direction of the casing 1, the first separation area 6 is located below the second separation area 5, the exhaust gas of the compressor enters the first separation area 6 located below through the gas inlet pipe 2, the gas enters the second separation area 5 after the first stage separation is completed in the first separation area 6, and the gas is discharged through the gas outlet pipe 3 after the second stage separation is performed in the second separation area 5. The shell 1 corresponding to the first separation area 6 comprises a first cylindrical part 12 and a conical part 13, the inner wall of the first cylindrical part 12 is connected with a separation part 4, the separation part 4 comprises a drainage part 41, a communicating part 42 and a blocking part 43, the drainage part 41 slants downwards along the inner wall of the shell 1 towards the axial direction of the shell 1, the bottom of the drainage part 41 is connected with the communicating part 42, the communicating part 42 is of a cylindrical structure, the lower part of the communicating part 42 is connected with a blocking plate 432 through a connecting part 431 (the blocking part 43 comprises the blocking plate 432 and the connecting part 431), the blocking plate 432 blocks the gas rotational flow direction in the first separation area 6, a gap is arranged between the communicating pipe and the blocking plate 432, the gas in the first separation area 6 enters the communicating pipe through the gap and cannot directly enter the communicating pipe along the gas rotational flow path, the blocking part 43 also adsorbs oil drops carried in the gas while changing the gas flow direction, oil drops carried in the gas flowing to the second separation zone 5 are reduced, thereby contributing to the improvement of the oil separation effect. Casing 1 structure that second separation zone 5 corresponds is second cylinder portion 11, is equipped with filtering component in the second cylinder portion 11 to filter the branch oil to the gas that gets into the second separator, lower whirlwind divides oil and last filtration branch oil to combine, and dual branch oil effectively reduces the volume of spouting oil.
When the oil separator of this embodiment is applied to the double-exhaust compressor, one path of exhaust in the double-exhaust compressor is the compressor of directly discharging from the cylinder, can not pass through structures such as motor in the compressor and oil baffle, leads to this way carminative oil yield to reach more than 10% (can reach 13% generally), can influence the operation in compressor and the return circuit that the compressor belongs to. When the existing oil separator is used for separating the channel gas, the oil output after separation is generally kept at 9%, and the operation requirement of the compressor is difficult to meet. If the way exhaust is used for oil separation through the oil separator of the embodiment, the oil output can be effectively reduced to 0.5%, the oil separation capacity is greatly improved, the pressure loss of gas can be reduced, and the exhaust pressure of the compressor assembly is ensured. The other path of exhaust gas of the compressor is discharged into the shell of the compressor from the cylinder, and the gas is subjected to oil separation through the structures such as the motor and the oil baffle plate in the compressor and then is discharged through the exhaust port in the shell.
Of course, the present embodiment is not limited to the application to the dual-exhaust compressor, all the compressors can be used, and for all the compressors, a better oil separation effect can be achieved, and the pressure loss of the gas in the oil separation process can be reduced.
In another embodiment of the present invention, a compressor assembly (not shown) is further provided, which includes a compressor and the oil separator in the above embodiment, and has all the advantages of the above embodiment, and therefore, the detailed description is omitted. The oil separator is connected to an exhaust port of the compressor, and separates oil from gas discharged from the compressor to reduce the amount of oil discharged.
Further, the compressor comprises two independent exhaust passages, each exhaust passage is provided with an exhaust port, and the oil separator is connected to the exhaust port directly communicated with the cylinder. When the compressor is a double-exhaust compressor, the oil separator is connected to an exhaust port directly exhausting from a cylinder of the compressor so as to separate oil from gas directly exhausted from the cylinder of the compressor, effectively reduce the oil output of the gas in the path, ensure that lubricating oil flows back into the compressor for lubrication, and further ensure the operation stability of the compressor. The other path of exhaust gas of the compressor is discharged into the shell of the compressor from the cylinder, and the gas is subjected to oil separation through the structures such as the motor and the oil baffle plate in the compressor and then is discharged through the exhaust port in the shell.
