Description

HIGH PERFORMANCE DUST COLLECTOR USING INHALATION FALLING AIR CURRENT}

The present invention relates to a dust collector that allows dust and dust to be filtered out and discharged as clear air when turbid air mixed with dust or dust in a workplace sucked by a fan motor passes through a filter cartridge. By pulsing the cartridge, dust and dust adsorbed on its surface can effectively collect fallout, easy removal and removal of the filter cartridge, improvement of filtration performance by switching the downdraft of the air flow of intake air, and manufacturing of the filtration section. It relates to a high performance dust collector using an easy suction downdraft.

In places where a lot of dust and dust are floating in the air, such as garment factories, silk mills, cotton mills, mills, loess products factories, grinding factories, cement factories, and steel mills, to protect workers' health and maintain a pleasant working environment. It is common to have a mobile dust collector in operation.

The mobile dust collector is equipped with a caster, a filter barrel equipped with a dust collector and a suction port constituting an upper part of the main body, a plurality of removable filter cartridges and swing filter plates mounted on the filter barrel, and dust adsorbed on the surface of the filter cartridge. It consists of a pulse valve to shake off dust and dust, an air tank, a fan motor to suck in the outside air, and an outlet for filtered air. The greatest strength of this dust collector is that it can filter air by moving from place to place.

In the conventional mobile dust collector, the suction port is located on the side of the filtration chamber, the filter cartridge is upright, and is mounted side by side in the transverse direction, and the discharge port is placed in the upper part of the filtration chamber. Therefore, this dust collector is called a cross-flow filtration dust collector because the outside air comes in from the side and climbs up the filter cartridge to the outlet.

When the dust and dust adhering to the surface of the filter cartridge are pulsed by the pulse valve, the fallout falling from the top of the filter cartridge tends to reattach to the bottom of the filter cartridge by continuous intake before leaving the filter cartridge. The dust collection efficiency was low.

The filter cartridge is composed of a flexible resin frame on the top, and is mounted in a single swing type filter plate by inserting it into the perforated filter hole, even if it is necessary to replace one filter cartridge among several filter cartridges. Whenever this happens, dust and dust from other filter cartridges are thrown out of the air, creating a new pollution problem and inconvenient filter cartridge replacement.

In addition, the installation of a swing filter plate, a pulse valve, an air tank, and a fan motor in a cramped space made the filter difficult to manufacture, and the maintenance and management of the pulse valve, the air tank, and the fan motor were inconvenient.

Accordingly, an object of the present invention is to provide a mobile dust collector having a fall filter which is separated from the filter cartridge effectively when pulsing, the filter cartridge is easily detachable, and is easy to manufacture.

The purpose is to form an inlet in the ceiling of the filter barrel to switch to the down stream to suck the outside air from the top down, and the upright filter plate so that the filter cartridge can be mounted horizontally suitable for filtration of the intake down stream and smooth exhaustion posture. The filter entrance of the filter barrel is equipped with a swing door, and on the surface of the swing door, a pulse valve for each filter cartridge and an air tank shared by pulse valves installed in a row or a row are shared so that the pulse valve and air can be opened without opening the swing door. It can be achieved by a high-performance dust collector using the suction downdraft of the present invention configured to enable maintenance and cleaning of the tank.

In FIG. 1, the inlet port 2 for introducing outside air turbidized with dust and dust into the filter tube 1 is relocated to the ceiling of the filter tube 1, and the fan motor 3 sucks the air of the filter tube 1 downward. It is installed in the lower part of the outside air so that the suction air flows through the filtration unit consisting of the filter cartridge to discharge the filtered air to the atmosphere.

One side of the filter container 1 is completely closed, and it is set as the entrance / exit 15 for a filter cartridge, and the opening door 4 is provided in this entrance 15. As shown in FIG. Moreover, the inside of the filter container 1 makes the filter plate 6 parallel to the swing door 4 upright, leaving the front discharge path 5 at the front. The filter plate 6 supports the tip of the filter cartridge which is drilled by inserting filter holes 7 of the same size in the vertical, horizontal, horizontal directions.

On the inner surface of the rear wall 8 of the filter cylinder 1 parallel to the filter plate 6, the filter holder 9 is attached to the filter hole 7 coaxially with the filter hole 7 and inserted into the filter hole 7 of the filter plate 6. Insert the rear end of the inserted filter cartridge to support it.

2, the air tank 10 is installed at the front of the sliding door 4, and the pulse valve 11 is installed at the air tank 10. The air tank 10 is made long so as to be shared by the horizontal or vertical filter holes 7, and the pulse valve 11 is on the line passing through the center of the filter hole 7 in the air tank 10 of each row. It is installed on the filter cartridge to blow dust and dust adhering to the surface of the filter cartridge by a so-called pulsing action that instantaneously injects high-pressure compressed air into the nozzle 12 toward the center of the cross section of the filter cartridge.

A connecting passage 13 connected to the exhaust duct 14 is installed below the front discharge passage 5, and an end of the exhaust duct 14 is connected to the inlet side of the fan motor 15.

The main body 20 on which the filter container 1 is mounted is provided with a hopper 21 for inducing fallout and gathering in one place, and a butterfly in the middle of the pipe part 22 for loading the dust bag from the hopper 21. The valve 23 is mounted to prevent the fall of the fallout when lifting the bag full of the fallout or when loading a new bag.

The filter cartridge 30 is a factory product having a soft resin frame attached to the front end of the corrugated pipe and a soft resin cap attached to the rear end of the corrugated pipe. The filter cartridge 30 is a well-known filter cartridge widely used in the field of indoor dust collector, and the resin cap is a filter ball ( It is slightly smaller than the radius of 7), and is easy to penetrate through the filter hole 7.

3 shows an arrangement example of the filter plate 6 and the filter holder 9.

If the dust collector is installed in a place within the workplace and the fan motor 3 is operated, the air in the filtration tank 1 is sucked out, and the turbid air in the room is sucked into the suction port 2 by the suction force at this time, and the filter cartridge 30 The dust dust sucked together when sucked into the countless micropores developed on the main surface of the filter is filtered on the surface of the filter cartridge 30, and only the pure air passes through the filter cartridge 30, and then the discharge passage 5 and the connection passage (13). And the exhaust duct 14 and the fan motor 3 are diffused into the room or the atmosphere.

If dust and dust adhere closely to the surface of the filter cartridge 30 during the dust collecting operation, the dust collecting efficiency is lowered. Preventing this is the pulse valve (11). The pulse valve 11 discharges the filter cartridge 30 by emptying by instantaneously spraying a high-pressure compressed air stored in the air tank 10 at a time difference according to the input program. At this time, the fallout dropped from the filter cartridge 30 is dropped into the space between the filter cartridge 30 to be carried in the dust collecting bag 24 by the hopper 21, when the filter cartridge 30 is lying down and pulsing The dust collecting efficiency is improved because the fallout is much lower than that of the conventional vertical filter cartridges.

Opening the door 4 when not in operation exposes the front ends of all the filter cartridges 30 at the same time, so it is easy to lift and replace the filter cartridge 30 that is extremely degraded or damaged due to aging.

The air tank 10 and the pulse valve 11 are also relocated on the outside of the sliding door 4 so that they can be easily operated and exchanged at any time as well as at the time of manufacture.

As described above, the present invention draws out the fresh air filtered through the filter cartridge loaded with the suction downdraft in the transverse direction, so that the fall of fallout caused by pulsing is significantly lower than that of the conventional filter cartridge method. Therefore, it is excellent in dust collection efficiency, the fall of filter cartridge is easy, and the air filtering is very efficient because the filtering effect of turbid air is high.

In addition, since the front end of all filter cartridges is opened when the door is opened, it is very easy to repair or replace the filter cartridge, and the fallout caused by the replacement of the filter cartridge also falls into the filter barrel, so the damage caused by the fallout is extremely small.

In addition, the outwardly relocated air tanks and pulse valves are very easy to attach and replace at the time of manufacture, as well as to replace and replace them.
