[0009] However, in the gas-liquid separator of the above-mentioned existing rotary compressor, the liquid refrigerant remaining in the casing 11 after being blocked by the diverter baffle plate 12 produces foam when it is heated and heats up, causing the liquid level to rise, and by This liquid refrigerant will enter the interior of the cylinder 5 through the gas guide pipe 13, which will not only reduce the reliability of the compressor, but also generate noise

Embodiment Construction
[0028] refer to figure 1 , the rotary compressor of the present invention comprises a casing 1 and a stator 2 and a rotor 3 of a motor mechanism arranged inside the casing 1, wherein a rotating shaft 4 is pressed into the center of the rotor 3, and a rotating shaft 4 is arranged below the rotating shaft 4 A compression mechanism that sucks and compresses refrigerant gas.
[0029] The compression mechanism includes: a circular cylinder 5 fixed on the inner wall of the casing 1; an upper bearing 6A and a lower bearing 6B that are close to the two sides of the cylinder 5 and pass through the supporting shaft 4; Rotating plunger 7 that rotates eccentrically in 5; the vane that is crimped on the outer cylindrical surface of plunger 7 and performs linear motion when plunger 7 performs whirling motion, and divides the interior of cylinder 5 into suction space and compression space (Fig. not shown in); it is arranged on the side of the shell 1 and connected to the gas-liquid separato...

The foam eliminator for gas-liquid separator in compressor features that it includes one casing with certain inside space and with upper end connected to the refrigerant pipe in the refrigerating circulating system; one flow separator set in the upper part inside the casing to separate gaseous refrigerant and liquid refrigerant from the refrigerant inflowing via the refrigerant pipe; one gas flow guiding pipe penetrating the lower part of the casing and with one end located below the flow separator and the other end communicated with the suction port formed on the compressor cylinder; and one interference board set radial below the gas flow guiding pipe to block foam inside the casing. The present invention can inhibit the foam generated of the liquid refrigerant inside the casing during temperature raising and eliminate foam before raising to the gas flow guiding pipe, so as to prevent liquid refrigerant from inflowing into the cylinder in case of abrupt raising of liquid refrigerant surface.
Description
technical field [0001] The invention relates to a foam removal device for a gas-liquid separator for a compressor. Background technique [0002] Usually, the gas-liquid separator is installed on the suction side of the compressor, which has the function of separating gaseous refrigerant and liquid refrigerant and preventing liquid refrigerant from entering the compression chamber. It is usually used for direct suction of rotary compressors that directly suck refrigerant. in the compressor. [0003] Such as figure 1 , 2 As shown, the existing rotary compressor is provided with the stator 2 and the rotor 3 of the motor mechanism inside the casing 1, wherein a rotating shaft 4 is pressed into the center of the rotor 3, and a suction and compression device is arranged below the rotating shaft 4. Compression mechanism for refrigerant gas. [0004] The compression mechanism includes: a circular cylinder 5 fixed on the inner wall of the casing 1; an upper bearing 6A and a lower...
