Abstract

PURPOSE:To obtain an air cleaner having a large filtering capacity of air by preventing a clogging of filtering body caused by dusts, by separating and collecting the dusts with the aid of a cyclone-type air cleaner provided to the inside of an upper casting, and collecting the remaining dusts by sticking with the aid of an oil tank placed beneath a lower casing. CONSTITUTION:A gas, flowing 4 into an upper casing 1, is whirled like flow passages 22 and 23 to cause a rapid whirling motion at its upper end by a whirl-inducing plate 7, and is whirled in a dust-separating cylinder 8 like flow passages 24, 25, and 26. Dusts incorporated in the gas are separated by centrifugal force and are sent to the inside of a dust collecting cover 10 like a flow passage 27 from a dust fly-out hole 9 provided to the top surface, and the gas is turned to flow downward like a flow passage 28 from the inside of the cylinder 8 of the outer peripheral part. Further, the gas is vertically flowed like a flow passage 29 to collide against the oil surface in an oil tank 15 attached to the lower end of a lower casing 2, thereby the remaining dusts incorporated in the gas are adsorbed by the oil surface. Then the gas is turned upward like a flow passage 30 to filter the dusts perfectly by a filter body 18 placed at the lower end of the casing 2, and is discharged from an exit pipe 19 through flow passages 31, 32, and 33.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an air purifier that prevents clogging caused by dust and increases air overcapacity in an air purifier that passes through dust contained in air or gas. To provide an extremely convenient air purifier that has the performance of a vacuum cleaner, can be used in any highly polluted area without deteriorating the performance of the engine or equipment, does not hinder work, and does not require any trouble in handling. The configuration of the present invention is to combine the upper and lower casings into one body, connect the gas inlet to the upper electrical body at the lower end, and install the gas outlet pipe at the upper end of the upper body. A conical or cylindrical partition tube with a large upper diameter is arranged, several rotating guide plates are provided with an oblique angle at the gas outlet around the upper end, and a wedge part is provided on the outer periphery of the partition tube. . In addition, a dust concentration separating cylinder with a dust escape hole is placed in the upper seat so as to cover the guide plate, and a dust collection cover is installed by replacing the music cylinder, and these are assembled into a fastener. Tighten the upper housing airtightly. Further, the lower end of the conical partition tube is fixed by an airtight membrane to the conical partition tube integrally attached to the center of the lower housing.

In the above structure, the gas flowing in from the inlet of the upper housing circulates inside the housing and reaches the upper part, causing rapid rotation by the rotating guide plate and centrifugally separating the dust contained in the dust separation cylinder 8. Dust flies out from the dust escape port inside and accumulates inside the dust accumulation cover. The gas flows downward from the inside of the upper partition tube, passes through the inside of the lower partition tube, and collides with the curved surface inside the oil tank, which is airtightly attached to the lower end of the lower housing with a fastener, and the remaining dust is adsorbed on the oil surface. .

The gas is then diverted upward again, and the remaining dust is completely removed by the f-weekly filter fitted into the upper part of the oil tank, that is, the lower end of the lower housing. This f-week holiday can be changed to various f-week holidays or shapes as necessary.

The gas that has been completely filtered out during the week off is passed through an outlet pipe provided at the upper end of the lower housing and is connected to the engine or equipment. After centrifugation and curved surface adsorption as described above, f
This air purifier is characterized by its ability to dramatically increase the excess capacity through its three-stage excess dust collection mechanism, which is completely available during weekend holidays, and which has unprecedented performance.

An example will be described with reference to the accompanying drawing. An upper housing 1 and a lower housing 2 are integrally joined by spot welding 3. A gas suction pipe 4 is attached to the outer circumferential wall of the upper housing 1 in the direction of contact with the gas, thereby causing the suction gas to have a swirling motion. The shape and mounting direction of this suction pipe can be freely changed as required. Inside the upper housing 1, a conical partition cylinder 5 with a large upper diameter is arranged. This conical partition tube may have a cylindrical shape or other shapes.

A gas outlet passage T' is integrally formed around the upper outer periphery of the conical partition cylinder 5, and @6, which is formed integrally with the outer part T', is fitted into the upper housing flange. A dust separating tube 8 is arranged to cover the integrated conductive plate T. This cover 10 is arranged, and these are integrally fastened to a part of the upper end of the upper housing 1 using a fastener 11 in an airtight manner.

In addition, the lower end of the upper conical partition tube 5 is formed so as to be airtightly fitted 13 with the cylindrical partition tube 12 attached to the center of the lower housing 2. tube 4
The gas flowing further takes a swirling flow path like the flow paths 22 and 23, reaches the upper end, causes a rapid swirling movement by the rotation guide plate 7, and swirls inside the dust separation tube 8 like the flow path 24252B, and the centrifugal force is The dust particles are separated from each other, and the dust reaches the inside of the dust collecting cover 10 through the dust ejection hole 9 on the top surface, as in the flow path 27, and is accumulated in the dust collecting part 14 on the outer periphery. On the other hand, the gas is diverted downward from the inside of the dust separation tube 8 as shown in the flow path 28 and
1', the oil flows vertically downward and collides with the curved surface in the oil tank 15 attached to the lower end of the lower housing 2, and the remaining dust is sucked up by the curved surface. Thus, the gas flows upwardly as shown in the flow path 30, and is attached to the upper part of the oil tank 15, that is, the lower end of the lower housing 2, integrally with the r-weekly support frame 16, 17, and the secondary support frame 1g1.
．． Complete r
The flow channels 31, 32, and 33 reach the upper space of the transparent body 18 and communicate with the outlet pipe 19 via \. Note that this outlet pipe 19 is attached to an engine, equipment, etc. with a flange 20.

The shape and other aspects of the mounting structure of this outlet pipe can be freely changed as necessary, and the oil in the oil tank 15 is undulated by the gas that descends and collides with it, and is pushed upward along the inner wall surface of the oil tank. In order to prevent
By arranging the retrograde oil plate 21 integrally with the oil return plate 7, it is possible to prevent oil wave motion.

This oil-flowing plate 21 is arranged as necessary, and it is possible to achieve this function even without this oil plate, and the presence or absence of the oil plate is optional.

As described above, the present invention includes a cyclone type air purifier device that separates and collects air by centrifugal force within the upper body. The efficiency with which dust is separated by the centrifugal force is somewhat moderate, but if the efficiency is good, about 70 to 80% can be separated.

Since an oil tank type air purifier structure is placed under the lower housing, the 20 to 30% of dust that is not centrifuged in the upper part collides with the oil surface in the lower oil tank and is collected with no adhesion. . However, since the dust that is centrifuged in the first stage is mainly heavy, the dust that comes to the second stage is lightweight, and it is difficult to get all of it to stick to the oil surface, and some of it does not stick to the oil surface. So in the third stage r week off, I completely f this.
It is something that will pass. Therefore, the amount of dust that comes to the excess body is extremely small, so it must be extremely large compared to the excess capacity of conventional air purifiers before clogging occurs and impairs the performance of the engine or equipment. This is the characteristic of the air purifier of the present invention.
