Description

A combined cyclone dust collector {Cyclone type dust collector}

The present invention relates to a combined cyclone dust collector, and more particularly, to a combined cyclone dust collector that separates foreign matter from air containing dust or other foreign matter by centrifugal force through a third order to remove foreign matter as much as possible, Thereby improving the filtration efficiency and extending the life span of the cyclone dust collector.

It is known that the filtration filter dust collecting apparatus in the dust collecting apparatus is capable of dust collection of 95% or more even in the case of fine dust of 0.01 탆.

However, in the conventional filtration filter dust collecting apparatus, as the filtration operation progresses, the dust layer collected in the filtration filter becomes thick, so that the pressure loss becomes high and normal operation becomes impossible.

Therefore, the dust collected on the filter filter surface must be shaken off by a periodic pulsing & cleaning operation.

In addition, since the pressure loss increases sharply when the dust load imposed on the conventional filter filter dust collector is high, a centrifugal dust collector (Cyclone) is installed at the front end of the dust collector to reduce the load on the filter filter dust collector, The collection amount of the filtering filter dust collecting device by dust has been reduced.

However, the centrifugal force dust collecting apparatus installed at the front end has low performance, and the dust collecting apparatus does not exhibit the performance at all in the case of fine dust due to careless operation maintenance.

Accordingly, Korean Patent No. 10-0242228 discloses a high efficiency integrated centrifugal filtration and dust collecting apparatus in which a centrifugal force and a filter principle are combined into one device in order to solve the above problems.

Such a high efficiency integrated centrifugal filtration and dust collecting apparatus collects primarily the dust particles which are introduced in the dust generating process of the refuse combustion process, the waste incinerator process, the cement manufacturing industry, and the steelmaking process by the centrifugal force principle And the dust particles not collected therein are collected by the upper filter, and the dust collecting principle of the two devices is combined into a single device.

However, in the above-described high efficiency integrated centrifugal type dust collecting apparatus, when the air having large dust particles caught by the centrifugal force in the outer cylinder rises to the filtration filter side through the inner cylinder, fine dust that falls to the dust reservoir at the lowermost position is caught by the filtration filter There is a problem that the filtration efficiency is lowered by the filtration filter and the life of the filtration filter is shortened.

The dust in the dust reservoir at the lower portion of the outer cylinder is descended along the inner wall surface of the outer cylinder and then re-raised by the air flow rising and returning to the upper space with the filter to reduce the filtration efficiency by the centrifugal force of the outer cylinder, There is a problem in that the life of the filter and the filtration efficiency are lowered by increasing the amount of dust flowing to the filter.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide an air- So that the filtration efficiency can be improved and the life of the filter can be prolonged.

The operation of the combined cyclone dust collector according to the present invention will now be described.

FIG. 6 is a view showing a working relationship of the combined cyclone dust collector according to the present invention.

As shown in the drawing, the combined cyclone collecting apparatus 100 according to the present invention sucks air containing dust or the like through the suction port 116 formed in the outer cylinder 112 of the cyclone unit 110.

At this time, the air sucked to the inside of the outer cylinder 112 is sucked into the inner side of the outer cylinder 112 by being eccentrically provided from the outer cylinder 112 and the centrifugal force is generated while rotating along the inner circumference do.

In this way, the air sucked into the inside of the outer cylinder 112 through the inlet 116 turns around the inner circumferential surface of the outer cylinder 112, and the foreign substances contained in the air are separated by the centrifugal force The air that has been primarily collected and separated by the collecting member 212 is allowed to move inward through the lower portion of the guide cylinder 122 while turning.

The air that has moved to the inside of the guide cylinder 122 is blocked by the first blocking plate 120 and is turned on the inner circumferential surface of the guide cylinder 122. By this centrifugal force, The separated air is collected in the collecting member 212 and the separated air moves inward through the lower portion of the first inner cylinder 124 while turning.

The air that has moved to the inside of the first inner cylinder 124 moves through the passage 142 formed by the diaphragm 140 and is discharged to the inlet 144, The foreign materials contained in the air are separated by the centrifugal force in the third direction and the separated foreign matter is discharged from the discharge cylinder 146 And is collected by the collecting member 212.

In the process of turning the outer circumferential surface of the second inner cylinder 132, the separated air is moved inward through the lower portion of the second inner cylinder 132 and supplied to the inside of the second inner cylinder 132 The filter unit 310 can be used as a filter unit.

As described above, the air supplied to the cyclone unit 110 separates the foreign substances from the air in the third order, thereby separating the foreign substances contained in the air as much as possible and supplying the foreign substances to the filter unit 310.

In addition, the moving air after separating the foreign substances contained in the air in the cyclone part 110 by the third order is completely removed from the dust contained in the air during the passage through the filter 314 of the filter part 310 So that only clean air is discharged to the outside through the discharge port 118.

Accordingly, foreign matter contained in the air is separated from the cyclone part 110 in the third cycle to minimize the amount of foreign matter moving toward the filter 314, thereby improving the filtration efficiency of the filter 314, ) Can be prolonged.

The foreign matter trapped in the collecting member 212 separated from the air in the cyclone unit 110 is supplied to the cyclone unit (not shown) by the airflow ascending and returning by providing the backflow preventing member 214 at the entrance of the collecting member 212. [ 110 to prevent foreign matter from flowing backward.

The foreign matter accumulated on the filter 314 of the filter unit 310 is jetted through the jet opening 418 provided in the supply pipe 416 to remove the air stored in the compression tank 414.

At this time, the foreign matter separated from the filter 314 by the air injected through the injection port 418 is collected by the collecting member 212 provided at the lower part.

Therefore, by periodically cleaning the filter 314 using the filter cleaner unit 410, the efficiency of the filter 314 can be improved and the life of the filter 314 can be prolonged.
