Description

Fine dust and odor removal device

The present invention relates to an apparatus for removing fine dust and odors, and more particularly, to efficiently remove a large amount of fine dust and odors generated in various factories or workplaces such as paint factories, and in particular, to be continuously used by using a roll filter. As a result, maintenance time and cost can be saved, and when the roll filter is used for a certain period of time and its performance deteriorates due to clogging, it detects this and automatically removes the contaminated filter and replaces it with a clean filter to increase work efficiency. It relates to a device for removing fine dust and odors.

In order to improve the residential environment and prevent environmental pollution, in places where fine dust or harmful gases and odors are generated, the emission concentration of fine dust and harmful gases and odors is enforced by law so that fine dust, harmful gases and odors are not released to the outside. To prevent environmental pollution or damage to the residential environment, industrial sites that emit large amounts of fine dust, harmful gases and odors must have expensive fine dust removal facilities and odor removal facilities, respectively. Removal facilities require considerable cost, so there is a problem in that it is difficult for small businesses to operate, and in particular, there is a problem in that a large amount of fine dust and bad odors generated in industrial sites cannot be effectively removed.

In order to solve this problem, in a device that sucks air, purifies it, and then discharges it, as the sucked air passes through a filter provided inside the housing, the fine dust contained in the air is collected in the filter, and the air from which the fine dust has been removed is discharged to the outside. Although a device for discharging to the ventilator is used, such a conventional device has a cumbersome problem in that the operator has to check whether the filter is clogged from time to time. There is a problem that takes a lot of this.

At this time, the fixing pin 720 is provided in a state moved forward by the elastic spring 721, and when the fixing pin 720 is pulled backward, the elastic spring 721 is compressed and then the pulling force is released. The fixing pin 720 moves forward by the restoring force of

Therefore, the first roller 200 fixedly coupled to the first roller holder 141 can be easily and conveniently separated through the detaching means 700 to remove the contaminated roll filter 400 wound around the first roller 200 . can

That is, in the present invention configured as described above, air containing fine dust and odor is sucked through the inlet 120 and passes through the roll filter 400, the fine dust is first collected and removed, and then the roll filter 400 is removed. As the filtered air passes through the carbon filter 190 , fine dust and odors remaining in the primary filtered air are secondarily collected and removed, and clean air is discharged through the outlet 130 .

At this time, if the roll filter 400 is clogged by contaminants as it is used for a certain period of time, the pressure in the inner space 110 of the body part 100 increases, and the differential pressure sensor 510 detects this and operates the driving motor 520 . operation, and as the driving motor 520 operates, the first roller 200 is rotated so that the contaminated roll filter 400-1 is wound around the first roller 200 and at the same time the second roller 300 is not driven. As the clean roll filter 400-2 wound around the second roller 300 is unwound while being rotated, it is automatically replaced with a new filter.

In addition, when the volume is reduced as the roll filter 400 wound on the second roller 300 is unwound, the rotary encoder 630 measures the reduced distance, and when the measured distance value falls below the set value, the warning light 640 ) to operate the warning light 640 by transmitting a control signal, so that the operator can replace the roll filter 400 .

As such, the device for removing fine dust and odors of the present invention efficiently removes a large amount of fine dust and odors generated in various factories or workplaces such as paint factories, and in particular, by using a roll filter, maintenance time and cost can be reduced. Of course, if the roll filter is used for a certain period of time and its performance deteriorates due to clogging, it detects this and automatically removes the contaminated filter and replaces it with a clean filter to increase work efficiency.
