After secondary filtering of the air, cleaning times of a filtering core are reduced, quality of inlet air is greatly improved, and service life of the combustion engine or the air compressor is prolonged.

Description

The air-filtering coarse filter

Technical field

The utility model relates to a kind of air-filtering coarse filter, is used for the preceding air coarse filtration of internal combustion engine or air compressor air inlet, belongs to mechanical engineering field.

Background technology

At present, the air-filtering method of before internal combustion engine or air compressor, using both at home and abroad is filtered air one time; And the refills that great majority adopt filter, and filter core receives great restriction service life.Especially internal combustion engine or air compressor are operated in the air quality rugged environment, and like places such as mine, stone pit, coal yards, it is more outstanding that the shortcoming that the cleaning of the paper filter element of a filtered air is frequent, service life is short shows.

Summary of the invention

The purpose of the utility model is to provide a kind of and can filters in advance the air inlet of internal combustion engine or air compressor, reduces the filter core maintenance times, improves the filter core air-filtering coarse filter in service life.

Technical solution:

The utility model comprises main filter box, secondary filter box, and main filter box bottom is provided with lubricating cup, and main filter box top is provided with air inlet pipe and cross over pipe; Air inlet pipe one end places the bottom in the main filter box; Be connected with protecting wire net, be placed with the oil resistant hollow ball in the protecting wire net, the air inlet pipe other end places main filter box outside; Secondary filter box bottom is provided with and connects lubricating cup; Secondary filter box bottom is provided with filter, and cross over pipe one end places upper end in the main filter box, and the other end passes secondary filter box and places the filter top; Cross over pipe and secondary filter box and connect that the gap is provided with organic ball between the lubricating cup; Air intake duct one end places the upper end in the secondary filter box, and the other end places secondary filter box outside, places the air intake duct of secondary filter box upper end to be provided with air-suction cover.

On the air inlet pipe of the utility model master filter box outside airscoop shroud is installed.

The utility model lubricating cup wall of cup is provided with oil scale.

The utility model is owing to carried out filtering in advance before getting into internal combustion engine or air compressor to air; Make and enter into internal combustion engine or air compressor has obtained purification; Reduced the clearing times of filter core, so improved the weak point in service life of internal combustion engine or air compressor.

The utility model advantage:

1) before being installed at traditional empty filter, makes an experiment, the air quality that gets into traditional empty filter is purified more than 90%, thereby solved the deficiency of the empty filter of above-mentioned tradition well.

2) because the air filtration media of the utility model is to adopt used oil but not the conventional paper filter core, therefore, the deficiency of traditional filtering air is improved widely.

3) the empty filter device of the utility model uses through actual, under abominable air quality situation, is improved more than 5-7 times the service life of traditional cleaner cartridge cleaner.Like: traditional air filter in actual use, filter core of cleaning in 2-3 days was changed a new filter core in 15-20 days; And after installing this sky filter additional, clearing up the filtration foreign material (increase some used oil, need not change any element) of the empty filter of a deuterzooid in 15-20 days, 3-5 changed once traditional filter core in individual month.The filtering effect is remarkable.

The specific embodiment

The utility model master filter box 1 bottom is an opened type, and main filter box 1 bottom is connected with lubricating cup 2, and lubricating cup 2 wall of cups are provided with oil scale 5; Main filter box 1 top is provided with air inlet pipe 7 and cross over pipe 11; Air inlet pipe 7 one ends place the bottom in the main filter box 1, are connected with protecting wire net 8, are placed with oil resistant hollow ball 9 in the protecting wire net 8; Air inlet pipe 7 other ends place main filter box 1 outside, are installed into gas hood 6 on the mouth of pipe; Secondary filter box 3 bottoms are opened type, secondary filter box 3 bottoms with connect lubricating cup 4 and be connected, connect and be provided with filter 13 in the lubricating cup 4; Cross over pipe 11 1 ends place upper end in the main filter box 1; The other end passes secondary filter box 3 and has placed filter 13 tops, cross over pipe 11 and secondary filter box 3 and connect that the gap is provided with organic ball 12 between the lubricating cup 4, and air intake duct 14 1 ends place the upper end in the secondary filter box 3; The other end places secondary filter box 3 outsides, places the air intake duct 14 of secondary filter box 3 upper ends to be provided with air-suction cover 15.Space in space in air inlet pipe 7, the main filter box 1, cross over pipe 11, the secondary filter box 3 and air intake duct 14 form the air communication mistake.

Oil resistant hollow ball 9 adopts organic or steel material is processed.

Filter space in the utility model master filter box 1, the secondary filter box 3 forms monolithic filter by cross over pipe 11 connections.Main filter box 1, secondary filter box 3 can be as scheming square cylindrical shape or other shapes also can processed, and promptly can as long as sky filtration journey can be satisfied as stated in their inner space.

The empty journey that filters:

Air flows into through air inlet pipe 2 from air inlet, and air-flow drives steel ball 9 rotation at a high speed that the exit is provided with through air inlet pipe 7 exits; Simultaneously, air-flow fully contacts with the used oil film 10 of steel ball 9 surface attachment, make in the air-flow with the molecule foreign material be adsorbed in the used oil film 10 on steel ball 9 surfaces air-flow be purified; Meanwhile, the air communication that slips over from steel ball 9 surfaces is crossed protecting wire net 8 and is directly blown to by cover 2 at the bottom of main filter box 1 and the main filter box and form---on used oil 10 surfaces that main filter box integrated bottom is deposited.The molecule foreign material that when this air-flow and used oil 10 surfaces fully contact, carry in air-flow are adsorbed on used oil 10 surfaces air-flow further purification in main filter box like this.Air-flow after the purification with because the amalgam that the machine oil particulate that air-flow forms the percussion of machine oil forms, get into by paying filter box 3 and paying bottom pair filter box integral body that cover 4 is formed at the bottom of the filter box through cross over pipe 11 together; The air-flow wraparound upwards through behind some organic balls 12, will have the amalgam of machine oil particulate formation and some remaining foreign material and the machine oil particulate in the gas and together stick on the organic ball 12, reach the purpose that purifies air fully.Cleaned air passes is used by internal combustion engine or air compressor suction through the air entry of air-suction cover 15 from air intake duct 14.，
