Description

Filter cartridge for dust collector {Filter Cartridge for Dust Collector}

The present invention relates to a filter cartridge for a dust collector, and more specifically, to a filter cartridge for a dust collector mounted inside a dust collector that collects foreign substances such as dust floating in the air. The filter media can be easily exchanged through a sliding operation. , relates to a filter cartridge for a dust collector that can improve the filtration efficiency of the filter media by allowing introduced air to pass through the entire filter media.

A dust collector is a device that sucks air containing dust or harmful substances into the dust collector, filters and collects the foreign substances floating in the air through a filter, purifies the air, and discharges fine dust or harmful gases to the outside of the dust collector. It has become an essential device in a situation where air pollution is becoming increasingly severe.

In particular, compared to everyday living environments, industrial sites often generate large amounts of fine dust or harmful substances during the process, which not only worsens the working environment of workers, but also causes foreign substances floating in the air during the process to be removed in certain fields such as semiconductor production. The number of cases where minimization is essential is increasing.

In order to achieve sufficient dust collection effect in such an environment, it is essential to use a filter with higher filtration efficiency of pollutants than before.

Furthermore, no matter how high the filter's efficiency, the lifespan of the filter is limited. Therefore, the greater the filtration amount, the more frequently the filter needs to be replaced, so the convenience of filter replacement is also becoming an essential part of the performance of the dust collector.

Considering this, cartridge filters are widely used because they have the advantage of having higher filtration efficiency compared to the space they occupy compared to other types of filters, such as bag filters, and that filter replacement is relatively easy.

However, most conventional cartridge filters have a circular cross-section, which is good for ease of installation and exchange of filter cartridges, but there is a limit to increasing the filtration efficiency of the filter because the area through which polluted air passes through the filter is limited. .

Accordingly, in order to increase the filtration efficiency of the filter, the cross-section of the filter media is rectangular or a rectangular-shaped filter (hereinafter collectively referred to as 'rectangular') in which either the width direction or the height direction is longer. It is being developed.

In the case of a rectangular filter, the area through which air passes through the filter increases compared to a conventional circular filter, thereby increasing filtration efficiency and capacity.

However, these rectangular filters are not only more inconvenient than conventional round filters when replacing the filter cartridge due to their long shape in one direction, but also, when air is introduced in a direction parallel to the long direction, the inflowing air destroys the entire filter. There is a problem that it is difficult to pass through, that is, the efficiency of the filter can be reduced depending on the direction from which the air flows.

The “filter cartridge for dust collector” according to the present invention was created to solve the above-described conventional problems. The purpose of the present invention is to facilitate the replacement of rectangular filter cartridges, which are cumbersome to replace due to the cross-sectional structure of the filter, and furthermore, to The purpose of the present invention is to provide a filter cartridge for a dust collector that prevents the efficiency of the filter from decreasing depending on the direction of the incoming wind due to its cross-sectional structure.

The filter cartridge for a dust collector according to the present invention includes a filter media through which external air flows in, a filter part including a filter fixing part formed along the outer peripheral surface of the filter media to secure the filter media, and the filter media. An air outlet through which the filtered air is discharged is formed, a filter mounting part having a sealing wall protruding downward by a predetermined length along the outer peripheral surface of the air outlet on the lower surface, and a folding part on one side of the filter mounting part. It may include a filter rail portion that is connected to enable rotational movement at a predetermined angle and includes a mounting rail that extends vertically and parallel from both ends of the folded portion and is coupled thereto.

Here, the filter media may have a cross-sectional shape in which one of the width direction side and the height direction side is longer.

Additionally, the length of the mounting rail may be longer than the length of the longer side of the cross-sectional shape of the filter media.

Meanwhile, the filter unit may be configured to be detachable through an operation in which the filter fixing unit slides along the mounting rail.

In addition, the filter rail unit further includes a stopper connected to one end of the mounting rail to enable rotational movement by a predetermined angle, and the stopper closes one end of the mounting rail on the side where the filter unit is inserted through the rotational movement. Thus, the filter part inserted into the mounting rail can be fixed so that it does not deviate from the inserted position.

Meanwhile, the direction in which the outside air flows into the filter media may be parallel to the longer side of the cross-sectional shape of the filter media.

In addition, the filter mounting part may further include an air baffle part formed in a direction perpendicular to the direction in which the external air flows into the filter media.

The “filter cartridge for dust collector” according to the present invention allows for easy replacement of rectangular filter cartridges through a replacement method using a sliding operation using a rail structure, and various filters with various cross-sectional side length ratios in one filter cartridge structure. Costs can be reduced by being able to mount media, and furthermore, the baffle structure allows air flowing in through the entire filter media to pass through, thereby preventing the filter's filtration efficiency from deteriorating.

Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention and the accompanying drawings, assuming that the same reference numerals in the drawings refer to the same components.

When it is said that one component "includes" another component in the detailed description of the invention or in the patent claims, this shall not be construed as being limited to consisting of only that component, unless specifically stated to the contrary, and other components shall not be included. It should be understood that it can include more.

Hereinafter, an example in which the filter cartridge for a dust collector according to the present invention is implemented will be described through specific embodiments.

Figure 1 is a diagram showing the overall structure of a filter cartridge for a dust collector according to the present invention.

Referring to FIG. 1, the filter cartridge for a dust collector according to this embodiment may include a filter unit 100, a filter mounting unit 200, and a filter rail unit 300.

The filter unit 100 is a part where pollutants such as dust contained in the air are filtered as polluted air flows in and passes through it. The filter media 110, which is the part where actual filtration takes place, has a cross-sectional shape with sides in the width direction. It may be formed into a cross-sectional shape in which one of the sides in the height direction is longer, a so-called rectangular shape or a similar shape.

The internal structure of the filter media 110 is generally formed to maximize the area through which air passes. For example, the material constituting the filter media 110 is repeatedly folded to form a continuous sawtooth shape. There are ways to do it, etc.

In order to increase the filtration efficiency of the filter media 110, it is desirable to configure the outer shape of the filter media 110 to maximize the folded structure described above.

In the case of a conventional cartridge filter, the cross-sectional shape of the filter media 110 is circular to form the folded structure of the filter media 110 as much as possible, while reducing the area occupied by the filter inside the dust collector, allowing more filters to be installed in the same area. This is to simplify the appearance and reduce the weight, making it easier to replace the filter cartridge.

However, since this conventional circular filter cartridge does not have a structure that maximizes the folded structure of the filter media 110 as described above, there is a problem in that there is a certain limit to improving filtration efficiency.

Additionally, because the cross-section is circular, when multiple filter cartridges are mounted, there is a problem in that a lot of extra area is created between filter cartridges where filters cannot be mounted.

When the filter media 110 is formed in a rectangular shape as in one embodiment of the present invention, the folded structure can be greatly increased compared to the conventional circular shape, thereby improving the filtration efficiency of each filter cartridge.

Furthermore, when placing a plurality of filter cartridges inside the dust collector 10, the extra area where the filter cartridges cannot be installed is reduced compared to the conventional circular shape, so the area occupied by the filter in the same area is increased compared to the prior art. It also has the effect of improving the dust collection performance of the entire dust collector.

Here, the ratio of the lengths of both sides of the cross-sectional shape can be changed to various values depending on the filtration efficiency value to be achieved.

Meanwhile, the filter fixing part 120 is formed in a shape corresponding to the cross section of the filter media 110 so that the filter media 110 can be fixed to the filter mounting part 200.

The filter fixing part 120 is formed on the upper surface of the filter media 110 along the outer peripheral surface of the filter media 110, and protrudes by a predetermined length in the horizontal and vertical directions from the outer peripheral surface of the filter media 110. It is formed to allow this to occur.

The filter unit 100 may be fixed to the filter fixing unit 120 as the stepped portion is inserted into the filter rail unit 300.

In addition, the filter fixing part 120 is made of a material with higher strength than the filter media 110, and is coupled to the upper surface of the filter media 110, so that the filter media 110 has a structure such as a folded structure. It can be fixed to maintain its rectangular shape without being dismantled.

Meanwhile, the filter mounting unit 200 allows the filter unit 100 to be mounted and fixed inside the dust collector.

Here, the air outlet 210 allows air filtered through the filter media 110 to be discharged to the outside.

The air outlet 210 is formed by forming a hole in a portion of the filter mounting part 200, and is formed in a shape corresponding to the cross-sectional shape of the filter part 100, so that air discharged from the entire cross-section of the filter media 110 is discharged all at once. It allows the air to be released effectively to improve the circulation efficiency of airflow.

Figure 2 is a diagram showing the overall structure of the filter cartridge for a dust collector according to the present invention as seen from below.

Referring to FIG. 2, a sealing wall 230 is formed on the lower surface of the filter mounting unit 200 and protrudes downward by a predetermined length along the outer peripheral surface of the air outlet 210.

The sealing wall 230 is connected to the filter unit 100 and the filter mounting unit so that the air discharged through the air outlet 210 through the filter media 110 does not leak anywhere other than the air outlet 210. (200) can seal the contact area.

When the filter fixing part 120 and the lower surface of the filter mounting part 200 come into contact with each other, an empty space is created at the border where they are in contact, and when air flows out, the speed of the air flow discharged to the outside is lowered, resulting in purified air. Since the external discharge of air is not smooth, the filtered air stagnates in the filter part, resulting in a decrease in overall filtration efficiency and airflow circulation efficiency.

Therefore, by forming the sealing wall 230, the above problems can be prevented by blocking air leaking to the outside at the boundary area.

In addition, the filter fixing part 120 of the filter media 110 is further provided with a gasket 121 to contact the sealing wall 230 to further improve the sealing effect.

The gasket 121 is provided at a portion of the filter fixing part 120 that contacts the sealing wall 230 to prevent empty space at the contact interface, thereby increasing airtightness. In order to effectively achieve airtightness, The gasket 121 may be made of an elastic material.

Meanwhile, the filter rail unit 300 allows the filter unit 100 to be attached and detached through a sliding operation.

Figure 3 is a diagram showing the operation of inserting the filter unit 100 into the filter rail unit 300. If explained with reference to this, the filter rail unit 300 is folded on one side of the filter mounting unit 200. It is connected to the unit 320 to enable rotational movement.

For example, it can be connected through a hinge structure, etc., so that it can rotate by a predetermined angle, as shown in 'b' in FIG. 3, and the connection structure is not limited to the hinge structure, but can be implemented by various means that can rotate by a predetermined angle. It can be.

Mounting rails 330 extending vertically and parallel are formed at both ends of the folded portion 320.

The mounting rail 330 is preferably formed to have a length longer than the length of the longer side of the cross-sectional shape of the filter media 110.

Furthermore, since the length ratio of both sides of the cross section of the filter media 110 can be changed to various values depending on the filtration efficiency to be achieved as described above, the filter media 110 can have cross-sectional shapes of various length ratios accordingly. It can be implemented.

Therefore, it is preferable that the length of the mounting rail 330 is adjustable according to the length of the long side.

Similarly, it is preferable that the length of the folded portion 320 is also adjustable according to the length of the shorter side.

According to this, without the need to separately provide individual filter cartridge structures for each of the filter media 110 having different cross-sections with various length ratios of both sides, filter media ( 110) can be used.

Meanwhile, the mounting rail 330 is configured to rotate up and down by a predetermined angle by being connected through the folding portion 320.

When explaining the operation of fixing the filter unit 100 to the filter mounting unit 200 through the filter rail unit 300 as described above, the user moves the mounting rail 330 downward by a predetermined angle, The filter fixing part 120 is seated on the mounting rail 330.

At this time, when the filter unit 100 is inserted into the mounting rail 330, the protruding step-shaped filter fixing part 120 rests on the mounting rail 330 and slides in the insertion direction. It is combined through movement.

Here, the upper surface of the mounting rail 330 or the lower surface of the filter fixing part 120 may be provided with a configuration to facilitate sliding operation, for example, a rotating wheel, etc. In addition, various equivalents to facilitate sliding operation are provided. Water can be used.

Here, a stopper 310 may be further provided at the end of the mounting rail 330 on the side opposite to the side where the folded portion 320 is formed.

The stopper 310 is connected to one side of the mounting rail 330 so that it can rotate at a predetermined angle in both directions. For example, it may be configured to rotate by a predetermined angle by being connected through a hinge structure, etc., and the connection structure is not limited to the hinge structure and may be implemented by various means capable of rotating by a predetermined angle.

The stopper 310 rotates in both directions and serves to open and close one end of the mounting rail 330 on the side where the filter unit 100 is inserted.

In more detail, when the filter unit 100 is rotated and tilted in one direction, one end of the mounting rail 330 on the side where the filter unit 100 is inserted is opened, so that the filter unit 100 is positioned inside the mounting rail 330. It can be slid and seated, and when the filter unit 100 is completely inserted into the mounting rail 330, it is rotated in the other direction to attach the mounting rail 330 on the side into which the filter unit 100 is inserted. One end is closed.

Through this, the stopper 310 prevents the filter unit 100 inserted into the mounting rail 330 from moving in the direction opposite to the insertion direction and prevents it from being separated from the inserted position.

When the filter part 100 is completely inserted into the mounting rail 330, the mounting rail 330 is moved upward again so that the sealing wall 230 and the filter fixing part 120 come into contact with each other.

Thereafter, the mounting rail 330 is fixed to the filter mounting portion 200 so as not to move downward through a fixing bar 340 formed at a predetermined distance from the portion where the stopper 310 is formed.

As in the present embodiment, the fixing bar 340 can be fixed by coupling to the filter mounting part 200 through a fixing bolt 341. It is not limited to the fixing bolt and can be fixed by various means such as a knob, etc. It can be implemented.

Meanwhile, if the above process is reversed, the filter unit 100 can be removed from the filter mounting unit 200.

Specifically, the fixing bolt 341 is loosened to remove the fixing bar 340, the mounting rail 330 is moved downward by a predetermined angle, the stopper 310 is rotated in one direction to open the filter unit, and the filter unit is opened. When the filter part 100 is moved in the direction in which (100) is discharged, the filter fixing part 120 is separated from the mounting rail 330 in a sliding motion along the mounting rail 330, and the filter part (100) is separated from the filter mounting part 200. 100) is removed.

Through the above operation, the filter cartridge according to this embodiment can easily replace the filter unit 100, whose life has expired, with a new filter unit 100.

Additionally, the filter rail portion 300 allows the filter cartridge to be more firmly fixed to the dust collector compared to conventional filter cartridges.

Air flowing in from outside and passing inside the dust collector passes through the filter cartridge at a very high speed because the airflow is induced through the blower.

The conventional filter cartridge is formed only of the filter media and the part that maintains the shape of the filter media corresponding to the filter fixing part 120 of the present invention, and it was common to install and fix only the fixing part inside the dust collector.

In this case, the filter cartridge is not firmly fixed inside the dust collector, and the filter cartridge may be separated from the dust collector due to the high speed of the airflow.

On the other hand, in the case of this embodiment, the filter fixing part 120 is not directly coupled to the inside of the dust collector 10, but the filter part 100 is coupled to the filter mounting part 200 through the filter rail part 300, Since the filter mounting unit 200 is coupled and mounted inside the dust collector 10, the filter cartridge is more firmly mounted inside the dust collector 10 than in the prior art, thereby preventing the above problems.

In particular, as described above, in the case of the filter rail part 300 that couples the filter part 100 to the filter mounting part 200, after the filter part 100 is fully inserted, the stopper 310 is rotated in the other direction. By closing one end of the mounting rail 330 on the side where the filter unit 100 is inserted, the filter unit 100 is primarily prevented from moving or being separated, and the fixing bar 340 is It is fixed to the filter mounting part 300 through, and ultimately, along with the folding part 320 and the mounting rail 330, all four sides of the top of the filter part 100 are fixed to the filter mounting part 200 in a 'ㅁ' shape. , In addition to the primary fixing effect of the stopper 310, it is possible to more firmly prevent the filter unit 100 from being separated.

Here, in this embodiment, in order to more firmly fix the filter cartridge inside the dust collector 10, each of the stopper, folding part, and mounting rail may be formed of a rigid material, for example, a metal material.

Meanwhile, in another embodiment according to the present invention, the filter unit 100 may be fixed to the filter mounting unit 200 through the stopper 310 without separately providing the fixing bar 340.

At this time, the stopper 310 can be fixed by coupling to the filter mounting part 200 through a separate fixing bolt. It is not limited to the fixing bolt and can be implemented by various means such as a knob that can be combined and fixed.

Meanwhile, the filter mounting unit 200 may further include an air baffle unit 220 formed in a direction perpendicular to the direction in which the external air flows into the filter media 110.

The baffle portion 220 is formed in a direction perpendicular to the direction in which contaminated air flows into the filter media 110 of the filter portion 100 mounted on the filter mounting portion 200. do.

Figure 4 shows a comparison between the air flow (a) in a filter cartridge without the baffle portion and the air flow (b) in the filter cartridge with the baffle portion.

Referring to FIG. 4, in this embodiment, contaminated air flows in from the rear of the filter cartridge. At this time, the direction (w) in which the air flows is the length of the side direction in the cross-sectional shape of the filter cartridge according to this embodiment. You can see that it is in a parallel direction.

In this case, when the baffle part is not formed as shown in (a) of FIG. 4, the incoming contaminated air comes into contact with the rear of the filter media 110 and passes directly through it, and the filter media 110 moves in the direction in which the air travels. Because it is formed thickly, the introduced air cannot penetrate the entire filter media 110 and can only pass through a portion of the filter media 110.

In this case, because the air is filtered using only a portion of the filter media 110, there is a problem in that filtration efficiency is reduced, resulting in a decrease in the dust collection performance of the dust collector.

Therefore, it is necessary to induce a flow of air so that the contaminated air flowing into the filter media 110 can pass through the entire filter media 110.

Referring to (b) of FIG. 4, when a baffle part is provided on the side where air flows in, the air (w') entering the filter media 110 directly contacts the rear of the filter media 110 and passes through the baffle part before penetrating. collides with the air flow and diverges to both sides of the filter media 110.

The branched air flow (w') moves along both sides of the filter media 110 to the front of the filter media 110, and in the process of moving, the air flowing into the entire area (s') of the filter media 110 can penetrate.

In this case, unlike (a), contaminated air can be filtered using the entire area of the filter media 110, thereby preventing the dust collection performance of the dust collector from being reduced due to a decrease in filtration efficiency.

In other words, while using a rectangular filter cartridge with higher filtration efficiency than before, it is possible to prevent the problem that filtration efficiency may be lower than that of a circular filter cartridge depending on the direction of the inflowing air.

Meanwhile, Figure 5 is a diagram showing how the filter cartridge according to this embodiment is actually installed inside the dust collector 10.

Referring to (a) of FIG. 5, the filter cartridge combined with the filter media 110 is inserted and mounted into the internal receiving space of the dust collector, and the contaminated air flowing into the filter cartridge through the inlet (not shown) on the rear is filtered. After being filtered through the cartridge, it is discharged to the outside of the dust collector as purified air through the outlet (11).

Figure 5(b) shows the air flow when the filter cartridge is actually installed inside the dust collector.

Contaminated air (w1) flowing into the rear of the filter cartridge first collides with the baffle part, branches off to both sides of the filter media 110, and flows into the entire filter media 110 (w2), and the filter media 110 ) The air filtered through ) changes direction and flows upward to the outlet 11 by the intake device provided on the top of the filter cartridge and is discharged to the outside through the outlet (w3).

The technical idea of the present invention was examined through several examples above.

It is obvious that a person skilled in the art to which the present invention pertains can make various modifications or changes to the above-described embodiments based on the description of the present invention. In addition, even if not explicitly shown or explained, a person skilled in the art may make various modifications including the technical idea of the present invention from the description of the present invention. is self-evident, and still falls within the scope of the present invention. The above embodiments described with reference to the accompanying drawings are described for the purpose of explaining the present invention, and the scope of the present invention is not limited to these embodiments.
