Abstract
The utility model relates to an air purifying device, which comprises a supporting frame, a shell, a filtering barrel which is arranged in the shell, and an air inlet and an air outlet which are arranged on the shell. The upper part of the filtering barrel is a venturi. The filtering barrel is composed of an outer barrel with through holes, and an inner barrel. Folded barrel-shaped filter paper is arranged between the inner barrel and the outer barrel. A spout above the corresponding venturi is installed on a pipeline. A through hole is arranged on a baffle plate of the corresponding inner barrel.
Description
The utility model relates to air cleaning facility, and specifically a kind of filter paper and Venturi tube of utilizing made filter element, and the filter that can carry out the self-cleaning gas spout of blowback to cartridge filter is arranged above venturi outlet.
Air compressor all is furnished with the inlet air filter usually, so that provide clean air to compressor.But this kind equipment all can not be self-cleaning filter element itself, therefore, the clean level of filtered air does not reach high-quality, and maintenance load is big.Secondly, the filter efficiency of used filter element is not high.
The purpose of this utility model is that design a kind ofly utilizes collapsible filter paper to make filter element, the filter of self-cleaning spout is installed, to overcome the problems referred to above above cartridge filter.
Its main technical schemes comprises air inlet and the air outlet (1) on cartridge filter (6) and the housing in support (5) and housing (2) and the housing, cartridge filter (6) top is Venturi tube (9), cartridge filter is by inner core (18) formation of urceolus (15) with the band through hole (19) of band through hole (16), between inside and outside tube, place folded filter paper formula tubular-filter paper (17), the spout (12) that is installed on the pipeline (3) is arranged in the top of corresponding Venturi tube (9).There is a screw rod (21) at cartridge filter (6) middle part, cartridge filter rests on the supporting plate (20) of screw rod bottom, the screw thread on screw rod (21) top cooperates with nut (22) on the dividing plate (4) that is installed in support (5) middle part, Venturi tube (9) is installed on the dividing plate (4), nut (22) is positioned at the center of Venturi tube (9), and the bottom surface of Venturi tube (9) should be greater than the inner core (18) of cartridge filter (6).On the dividing plate (4) of corresponding inner core (18), through hole (14) is arranged.
Because the utility model adopts collapsible tubular filter paper, compare its filter efficiency height, the air quality height after the filtration with original filter element, the self-cleaning spout that adds the Venturi tube top again, can carry out pulse backblowing to filter paper, the dust on the cleaning filter paper makes the filter efficiency of filter paper higher, and need not keep in repair substantially, therefore, efficient was both high, and operation is convenient again.
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is cartridge filter and venturi tube structure figure.
Fig. 3 is A-A cutaway view of Fig. 2.
As shown in the figure: housing (2) is installed on the support (5), there is dividing plate (4) at the middle part of housing (2), a plurality of Venturi tubes (9) are installed on the dividing plate, on the dividing plate at Venturi tube (9) center nut (22) is installed, supporting plate (20) is arranged at screw rod (21) bottom in the nut, cartridge filter (6) just rests on this supporting plate, tightens screw rod, just cartridge filter can be installed in dividing plate (4) below.
Cartridge filter comprises inner core (18) and urceolus (15), on inside and outside tube (18), (15) through hole (19), (16) is arranged, and is full of collapsible tubular filter paper (17) between inside and outside tube.On the dividing plate (4) of corresponding inner core (18), through hole (14) is arranged
On the pipeline (3) of Venturi tube (9) top spout (12) is installed, control valve (11) also is installed on the pipeline.Two at housing also are equipped with electric control switch (8) and rain cover (13).(7) among Fig. 2 are the handle of screw rod (21).
During work, atmosphere is entered in the cartridge filter by the through hole of urceolus, is expelled to Venturi tube by the through hole on the inner core after filter paper filters, and sends for compressor through outlet and uses.When needs are self-cleaning, open valve (11), compressed air sprays in the Venturi tube through pipeline, nozzle, and the dust on the filter paper is blown off.Self-cleaning program can be controlled by computer.
Claims (2)
1, self-cleaning air filter, comprise air inlet and air outlet (1) on cartridge filter (6) and the housing in support (5) and housing (2) and the housing, cartridge filter (6) top is Venturi tube (9), it is characterized in that inner core (18) formation of cartridge filter (6) by urceolus (15) with the through hole (19) of band through hole (16), between inside and outside tube, place folded filter paper formula tubular filter paper (17), in the top of corresponding Venturi tube (9) spout (12) that is installed on the pipeline (3) is arranged, on the dividing plate (4) of corresponding inner core (18), through hole (14) is arranged.
2, filter according to claim 1, it is characterized in that there is a screw rod (21) at cartridge filter (6) middle part, cartridge filter rests on the supporting plate (20) of screw rod bottom, the screw thread on screw rod (21) top cooperates with nut (22) on the dividing plate (4) that is installed in support (5) middle part, Venturi tube (9) is installed on the dividing plate (4), nut (22) is positioned at the center of Venturi tube (9), and the bottom surface of Venturi tube (9) should be greater than the inner core (18) of cartridge filter (6).
