Description

[Detailed description of the invention] This invention has the function of preventing clogging of the filter body and maximizing the filtration capacity by centrifuging the dust contained in the air or gas in the filter. The present invention provides an extremely convenient vertical cyclone filter structure that does not require any trouble.

To explain the embodiment with reference to temperature control, a gas suction pipe 2 is attached tangentially to the outer peripheral wall surface of the filter case 1, thereby causing a swirling inflow movement of the gas.

Further, a cylindrical partition tube 3 is provided inside the filter housing 1, and a flange 4 that tightly contacts the filter housing flange and several rotation guide plates 5 with inclined angles at the air outlet holes are integrally attached to the upper end of the partition tube 3. The upper and lower ends are configured so that they fit into the filter housing 1 in close contact with the filter housing 1.
A cylindrical swirling flow passage 6 is formed between the intake pipe 2 and the suction pipe 2 to form a flow passage that rotates from the inflow passage 22 like a flow passage 23.

Also, in the center of the partition cylinder 3, there are end plates 11 at the upper and lower ends.
．． A filter body 10 made of a flower-shaped filter paper or the like, which is integrally formed with a reinforcing cylinder 13 made of a perforated plate or the like, is arranged.

Note that the configuration of this filter body can be appropriately selected from various filter media and shapes.

The outlet of the filter body 10 is connected to various devices such as an internal combustion engine or an air pump through an outlet pipe 7 provided at the center bottom of the filter housing 1.

Further, the filter body 10 is fixed by fixing the end plate 12 to the support bridge 8 which is integrally formed with the outlet pipe 7 with a tightening screw 14.

Further, a dust separation cylinder 15 is arranged to cover the filter body 10 from above and open a dust escape hole 16 in a part of its top surface, and a swirl flow path 17 is formed therebetween.

Further, a dust collection cover 18 made of transparent resin or the like is arranged to cover the separation tube 15 and form a swirling flow path 19.20, and then the filter housing 1. The dust separation tube 15 and the dust collection cover 18 are fixed together.

In such a structure, the suction pipe 2 attached to the filter housing 1
The inflowing gas swirls into the channels 22 and 23, and the dust-containing gas flows upward while swirling, causing a sharp swirling motion by the swirl guide plate 5, and the dust swirls sharply along the inside of the dust separation tube 15. The inner wall of the cover 18 is pushed upward through the flow path 24°25.26 and pops out from the dust escape hole 16 provided on the top surface of the dust separation cylinder 15 into the space flow path 19.20 in the dust accumulation cover 18. While swirling along the flow path 27, the dust settles in the lower part of the dust collecting section 28, where the dust is accumulated.

On the other hand, the gas containing dust is centrifuged through the flow path 25 to the filter body 10.
The water is almost completely filtered by the filter, flows into the filter body 10, and reaches the outlet pipe 7 like the flow path 29.

The outlet pipe 7 is connected to various devices such as an internal combustion engine or an air pump, and is fixed with a tightening band 9.

The dust separated in this way is collected in the dust collection cover 18 made of transparent resin or the like on the upper part, and its condition can be visually observed from the outside (the transparent part may be only the collection part), and it can be easily removed using the fastener 21 to remove the dust. It is a vertical cyclone type filter which has an extremely rational structure, and the filter body 10 inside can be easily attached and detached using the tightening screws 14, making it easy to wash and clean.
