Description

Air filter assembly having the reinforced supporter assembled therein

The present invention relates to an air filter assembly installed in a clean room of various industrial sites such as semiconductor production equipment and pharmaceutical equipment, and more particularly, a T-shaped support frame inserted into the air filter to support the air filter. Reinforcement that can perform faithfully the original function of the support frame to maintain the shape by reinforcing the strength of the air filter by strengthening the strength of the air filter by making it in the form of beam of cross section. An air filter assembly having a supported support frame.

In general, facilities such as waste incinerators, factory chimneys, and various smelting facilities are equipped with an air purifier to remove harmful substances and dusts contained in the exhaust gas, and an air purifier is used to maintain a clean environment at home. There are many cases. In addition, a clean room is provided in a place where a very clean environment such as a pharmaceutical facility or a semiconductor manufacturing facility is required. The air purifiers used in the facilities listed above are equipped with air filters.

In particular, the air filter used for the air conditioning of the room has been developed in a wide variety of types depending on the size and use. The air filter is a filtration means for filtering dust or foreign substances in the air supplied to the room. Especially in a clean room in which a semiconductor production process is performed, the cleanliness and air flow characteristics of the air passing through the air filter are closely related to the product quality. It is a well known fact. In general, the air filter is mainly installed on the ceiling or the wall of the room, and the air passing through the air filter forms a stable airflow immediately to maintain a constant air flow throughout the room. This air flow characteristic is a very important factor that greatly affects the productivity in the semiconductor production facilities that are affected by minute changes in the external environment.

The air filter assembly installed in the clean room is usually made up of the separator type and the hot-melt type. A conventional separator type air filter assembly is shown in FIGS. 1A and 1B.

1A is a front view of a conventional separator type air filter assembly, and FIG. 1B is a side view thereof.

In the separator type, a separator 14 is inserted between media 12 formed by folding a filter cloth as shown in FIG. 1A to secure a space for air to flow. As shown in the figure, such a separator-type air filter assembly is fixed by combining an air filter 10 having a media and a separator overlapping in the support frame 20. Thus, the structure of inserting and fixing the air filter 10 only to the support frame 20 does not cause a big problem in a small and small filter having a thickness of about 610 mm and a thickness of about 120 mm.

However, as the air filter becomes larger and thinner, it is difficult to maintain its shape and strength by assembling the air filter into the support frame as described above. Therefore, as shown in Figures 2a and 2b has been developed a structure for reinforcing the bearing capacity of the intermediate portion by inserting a support frame in the middle of the air filter.

FIG. 2A is a front view of the air filter assembly in which a reinforcing support frame is inserted into a middle portion of a conventional large air filter, and FIG. 2B is a cross-sectional view taken along the line A-A of FIG. 2A.

As shown, the air filter 40 is mounted in the support frame 30 of the rectangular frame, and the support frame 50 is inserted in the vertical direction in the middle of the air filter 40. The upper and lower ends of the support frame 50 are usually in contact with the inner surface of the support frame 30, and the contact portions are attached to each other via adhesives 52 and 52a. That is, the support frame 50 is applied to the upper and lower ends, respectively, in the state inserted into the air filter 40, the adhesives 52 and 52a are adhered to the upper and lower inner central portions of the support frame 30 in contact therewith, and are vertically fixed. .

In this way, when the upper and lower ends of the support frame are glued to the upper and lower inner surfaces of the support frame corresponding to each other, the adhesive is first applied to one of the upper and lower ends of the support frame, and then attached to the corresponding surface of the corresponding support frame. It was completed by inverting, applying adhesive to the other end and attaching it to the corresponding surface of the support frame. Thus, in the structure in which the conventional support frame is inserted, since one side is hardened and then bonded to the other side, it is difficult to accurately position and takes a long time to manufacture, and also causes a problem that the adhesive position is displaced during curing. That is, as shown in FIGS. 2A and 2B, a deviation of E is generated from the set position, which immediately changes the air distribution passing through the air filter so that the function of the air filter is not properly exhibited. As a result, this causes a change in the environment of a manufacturing place such as a clean room using an air filter, resulting in a problem of increasing the defective rate and lowering the productivity.

Furthermore, the conventional support frame is a straight flat frame, and a slight external force, in particular, a deformation such as bending or twisting occurs easily in an external force substantially perpendicular to the longitudinal direction of the support frame and acting in the thickness direction of the support frame. This resulted in not only the support frame not protecting the filter properly, but also causing the deformation of the overall appearance of the filter assembly to increase the product defect rate.

Accordingly, an object of the present invention is to solve the above-mentioned drawbacks, a flat support frame of a straight shape by manufacturing a support frame inserted into the air filter to support the air filter in the form of a beam (T-shaped cross section) The present invention provides an air filter assembly having a reinforced support frame, which is more resistant to deformation such as warpage and torsion, and can faithfully perform the original function of the support frame to maintain a constant shape by reinforcing the strength of the air filter.

In addition, Figure 7 is a perspective view showing a state in which the support frame is coupled to the support frame.

This embodiment shows an embodiment applied to a hot-melt air filter. The structure of the present invention to be described below can be equally applied to a separator formula.

As shown, the air filter 80 of the rectangular plate-like body is mounted and coupled in the support frame 70 of the rectangular frame coupled to the four frames of the top, bottom, left and right. In this way, the four sides of the air filter 80, the upper, lower, left, and right frames 72a to 72d of the support frame 70 by holding the air filter 80 is firmly fixed. And, the mesh screen 90 is attached to the front and rear surface side of the air filter 80. However, in the case of the hot-melt type illustrated in the structural example, the air filter 80 folds the filter cloth 82 in a zigzag form in a horizontal direction so that a predetermined interval is spaced apart from each other in the folded state in the state of stacking the plurality of unit filters up and down. By adhering the upper and lower ends in an hot-melt manner using an adhesive, a passage through which air passes is formed. Therefore, the hot-melt adhesive parts 84 formed along the horizontal direction are formed at equal intervals up and down, and the air passages 86 of the unit filters hot-melt bonded up and down are both vertically and vertically as shown in FIG. 5. Communicating. Thus, the air filter has a structure that is connected by folding the filter cloth, the larger the thin filter, the weaker the bearing capacity of the middle portion.

In the present invention, in order to reinforce the weak supporting force of the air filter 80, the support frame 100 is inserted into the air passage 86 communicating in the vertical direction of the air filter 80 at the intermediate position of the air filter 80. I'm making it. In general, the support frame is made of a thin plate and has a long length, so that the support frame is vulnerable to bending or torsion due to external force acting in the vertical direction in the longitudinal direction, that is, in the thickness direction of the support frame. In order to reinforce this, the support frame 100 has an external force acting in a substantially vertical direction in the longitudinal direction by connecting a reinforcement plate 104 perpendicular thereto (thickness direction) to at least one side of the elongated plate-shaped main plate 102. To improve the history. In detail, as shown in FIGS. 6A and 6B, the reinforcing plate 104 is integrally formed on one side of both sides in the longitudinal direction of the main plate 102 of the support frame 100 to form a substantially T-shape. Promote the resistance to deformation caused by vertical external force in the direction. At this time, the main plate 104 is relatively wide, it is preferable that the reinforcing plate 104 is narrow in comparison. As the method of connecting the main plate 102 and the reinforcing plate 104, the reinforcing plate 104 and the main plate 102 may be integrally formed by a molding method such as extrusion molding or injection molding, and on the other hand, the width A narrow reinforcing plate 104 may be welded to one side of the wide main plate 102 to be integrated. In addition, various bonding methods, such as bonding or other bolting, may be used.

In particular, the main plate 102 of the support frame 100 may take the form that the thickness becomes thinner toward the open end from the side connected to the reinforcing plate 104 in order to improve the air flow. Further, the thickness is reduced while forming a streamlined toward the open end of the main plate (102). In addition, the upper and lower ends of the reinforcing plate 104 protrude a predetermined length from the upper and lower ends of the main plate 102. The upper and lower protrusions of the reinforcement plate 104 function as coupling jaws 106a and 106b for inserting and mounting the corresponding portions of the support frame 70. Of course, coupling grooves 74a and 74b to which coupling jaws 106a and 106b may be fitted are provided at upper and lower portions of the support frame 70.

Here, the coupling jaw (106a, 106b) and the coupling groove (74a, 74b) is formed one by one above and below as illustrated, it is preferable to form a wide straight protrusion and groove in the thickness direction of the main plate (102). In this case, as shown in Figure 7, after inserting the coupling jaw (106b) provided at the lower end of the support frame 100 in the coupling groove (74b) formed in the lower frame (72b) of the support frame 70, the support frame ( When the coupling jaw 106a provided at the top of the 100 is inserted into the coupling groove 74a of the upper frame 72a, the support frame 100 is not supported at all based on the vertical direction and the width direction without any inclination or misalignment. 70 is easily combined in the correct position.

In the present embodiment, one support frame 100 is inserted in the middle position of a general air filter of a general size, a thin plate-type air filter having a height of about 1200 mm and a width of about 75 mm. Many of them may be inserted in between. In this way, the present invention is a reinforcement plate 104 of the support frame 100 is protruded a predetermined length from the upper and lower ends of the main plate 102 to be used as the coupling jaw (106a, 106b) to facilitate the coupling at the same time position accuracy of the coupling Can increase.

On the other hand, the above-described support frame 100 may be provided with a reinforcing plate 104a not only on one side of the main plate 102, but also on the other side thereof so that its cross section may have an approximately I shape.
