Technical Field
The invention relates to the technical field of air conditioners, in particular to an oil content barrel, a screw compressor and an air conditioner.
Background
Screw compressors are an important component of commercial air conditioning screw units, known as the "heart" of commercial air conditioners. With the development of frequency conversion technology, the frequency conversion screw machine gradually occupies a place in the market. The variable frequency motor adopted by the variable frequency technology can change the rotating speed of the rotor of the screw machine so as to control the exhaust capacity of the compressor, and the variable frequency screw machine can be suitable for various occasions and environments and can finely adjust the environmental temperature, so that the variable frequency screw machine has the characteristics of energy conservation, wide application range and the like.
As shown in fig. 1, the oil content barrel of the existing variable-frequency screw machine has no flow guiding structure, when the mixed gas of the refrigerant and the frozen oil comes out from the exhaust pipe a4 and enters the separation cavity a3, the gas can flow along the inner wall of the oil content barrel shell a1, so that the mixed gas at the inner wall of the barrel has higher flow velocity, but the mixed gas is the joint of the oil content filter screen a2 and the oil content barrel, and the oil content effect is poor.
Disclosure of Invention
In order to overcome the technical defects, the invention solves the technical problems of providing an oil content barrel and a screw compressor, which can improve the oil content efficiency.
In order to solve the technical problems, the invention provides an oil content barrel which comprises an end cover, an oil content filter screen arranged in the oil content barrel and a separation cavity formed between the oil content filter screen and the end cover, wherein a guide ring is arranged at one side of the separation cavity, which is close to the oil content filter screen, and is used for guiding gas discharged by an exhaust pipe of a compressor to the oil content filter screen.
Further, one end of the guide ring is a flat port, the other end of the guide ring is a necking port, the flat port is covered on the oil filter screen, and the necking port faces the end cover.
Further, the height of the guide ring is less than or equal to 5mm.
Further, the air exhaust pipe is positioned on the inner side of the guide ring.
The invention also provides a screw compressor which comprises a cigarette holder and an oil content barrel, wherein the cigarette holder is communicated with an air passage of the oil content barrel.
The invention also provides an air conditioner which comprises the screw compressor.
Therefore, based on the technical scheme, the oil content barrel is provided with the guide ring at one side of the separation cavity, which is close to the oil content filter screen, the guide ring promotes the mixed gas of the refrigerant and the frozen oil to be more uniform, and promotes the mixed gas flowing along the inner wall of the oil content barrel to flow to the center of the oil content barrel, so that the oil content efficiency is improved. The screw compressor and the air conditioner provided by the invention have the beneficial technical effects correspondingly.
