Abstract

The utility model relates to an inlet filter which is used for filtering a gas going into a screw compressor. An upper end socket is fixed at the upper end portion of a cylinder, while a lower end socket is fixed at the lower end portion of the cylinder; a vent nozzle is arranged on the upper end socket; a drain outlet is formed in the lower end socket; a gas inlet is formed in the wall body of the upper section of the cylinder; a gas outlet is formed in the wall body of the lower section of the cylinder; a retaining ring is fixed on the inner wall of the cylinder; the plane of the retaining ring intersects with the cylinder by an acute angle; filter cartridges are mounted on the retaining ring; the filter cartridge which is located at the side of the gas inlet is shorter than the filter cartridge which is located at the side of the gas outlet; a lifting lug is fixed on the upper end socket; a supporting leg is fixed on the lower end socket. The inlet filter is capable of effectively filtering the gas, improving the working efficiency of the screw compressor and prolonging the service life of the screw compressor.

Description

Inlet filter

Technical field

The utility model relates to a kind of device for the gas of access helical-lobe compressor is filtered, especially a kind of inlet filter.

Background technique

At present, the gas of access helical-lobe compressor is not filtered, in gas, impurities can be deposited in helical-lobe compressor when compression, after long-time use, can make the working efficiency of helical-lobe compressor reduce, energy consumption increases, and even makes helical-lobe compressor produce fault and cannot move.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can effectively filter, improve the working efficiency of helical-lobe compressor, the inlet filter that extends the working life of helical-lobe compressor to the gas of access.

The technological scheme providing according to the utility model, described inlet filter, comprise cylindrical shell, upper cover and lower seal head, upper end portion at cylindrical shell is fixed with upper cover, underpart at cylindrical shell is fixed with lower seal head, on upper cover, be provided with drain, on lower seal head, be provided with sewage draining exit, on the epimere wall body of cylindrical shell, be provided with suction port, on the hypomere wall body of cylindrical shell, be provided with air outlet, at the inwall of cylindrical shell, be fixed with and put circle, it is crossing that plane and the cylindrical shell of putting circle place is acute angle, filter cylinder is installed putting on circle, and the height that is positioned at the filter cylinder of suction port one side is less than the height of the filter cylinder that is positioned at air outlet one side, on upper cover, be fixed with hanger, on lower seal head, be fixed with supporting foot.

Described drain is arranged on the top middle portion position of upper cover.

Described sewage outfalls setting is in the center bottom position of lower seal head.

Described suction port is arranged on the epimere left side wall body of cylindrical shell.

Described air outlet is arranged on the hypomere right side wall body of cylindrical shell.

The utility model can filter effectively to the gas of access, has improved the working efficiency of helical-lobe compressor, has extended the working life of helical-lobe compressor.

Embodiment

Below in conjunction with specific embodiment, the utility model is described in further detail.

This inlet filter, comprise cylindrical shell 1, upper cover 2 and lower seal head 3, in the upper end portion of cylindrical shell 1, be fixed with upper cover 2, in the underpart of cylindrical shell 1, be fixed with lower seal head 3, on upper cover 2, be provided with drain 4, on lower seal head 3, be provided with sewage draining exit 5, on the epimere wall body of cylindrical shell 1, be provided with suction port 6, on the hypomere wall body of cylindrical shell 1, be provided with air outlet 7, at the inwall of cylindrical shell 1, be fixed with and put circle 8, it is crossing that plane and the cylindrical shell 1 of putting circle 8 places is acute angle, filter cylinder 9 is installed on 8 putting circle, and the height that is positioned at the filter cylinder 9 of suction port 6 one sides is less than the height of the filter cylinder 9 that is positioned at air outlet 7 one sides, on upper cover 2, be fixed with hanger 10, on lower seal head 3, be fixed with supporting foot 11.

Described drain 4 is arranged on the top middle portion position of upper cover 2.

Described sewage draining exit 5 is arranged on the center bottom position of lower seal head 3.

Described suction port 6 is arranged on the epimere left side wall body of cylindrical shell 1.

Described air outlet 7 is arranged on the hypomere right side wall body of cylindrical shell 1.

When the utility model is used, from suction port 6, access gas to be filtered, gas is after filter cylinder 9, liquid and dust contained in gas will stick on filter cylinder 9, after forming drop, fall, run up to after a certain amount of and discharge by sewage draining exit 5, after filtering, clean gas accesses helical-lobe compressor again.
