Description

Technical Field

[0001] The utility model relates to the technical field of screw compressors, in particular to an oil-gas separator for a screw compressor unit. Background Art

[0002] Screw air compressor is a kind of compressed air equipment widely used in the industrial field. Its working principle is to compress the air through the rotation of the screw and push the compressed air to the next stage of use through the exhaust pipe. When the compressed air flows through the screw, due to the friction and heat generated by the screw, a certain amount of oil will be squeezed out to form an oil-gas mixture. The oil-gas separator is a device specially used to separate oil and dirt, which is widely used in various air compression equipment. The function of the screw air compressor oil-gas separator is to separate the oil and water mixed in the air to make the compressed air purer.

[0003] Existing oil-gas separators for screw compressor units usually separate oil and gas through a filter element in a separation barrel, and discharge the separated oil and air through an oil drain pipe and an exhaust pipe, respectively. However, the filter element in the separation barrel will be clogged by particles carried in the oil and gas after long-term use, so the filter element needs to be replaced regularly. The separation barrel is usually installed with a sealed box cover by bolts, which is inconvenient to replace the filter element. The filter element replacement rate is poor, which reduces the working efficiency of the screw compressor. Utility Model Content

Since the separation cylinder 6 of the oil-gas separation barrel 2 is fixed in position by the connecting plate 5, the air collecting hood 7 and oil collecting hood 8 are separated from the separation cylinder 6, which facilitates the replacement of filter element 15 in the separation cylinder 6 and the replacement of filter element 2 18 in the oil collecting hood 8, thereby improving the replacement rate of filter element 15 and filter element 2 18.
