Description

Horizontal winding type filter {Horizontal winding type filter}

The present invention relates to a filter, and more particularly, to a horizontally wound type filter that is easy to use.

Filters purify the air by selectively removing impurities. The filter is made of a porous material capable of collecting impurities and is easy to process in most cases. Therefore, it has a wide range of uses and various application methods.

In the case of industrial filters, they are often used to treat exhaust gases and the like. Exhaust gas has a relatively large capacity, flow rate, pressure, etc. compared to everyday treatment targets, so various types of applications have been attempted depending on conditions. For example, conventionally, a filter in the form of a bag filter has been applied to various facilities (Korean Patent No. 10-1846398, etc.).

However, since the filter is quickly consumed as it is exposed to high-concentration exhaust gas, it needs to be replaced quickly in order to maintain high treatment efficiency. Conventionally, this part has not been very satisfactory, so the application of a filter that can be used while winding or unwinding in a roll form has also been attempted. However, in the case of such a filter, as the filter is spread wider, sagging occurs due to a load, so that it is not easy to use, and a technical alternative is needed.

Republic of Korea Patent Registration No. 10-1846398, (2018. 04. 06), specification

The technical problem of the present invention is to solve the above problems, and to provide a horizontally wound type filter that is easy to use because it can prevent sagging when unfolded in the horizontal direction.

The technical problem of the present invention is not limited to the problems mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art through the following description.

The horizontal winding type filter according to the present invention includes a filter sheet wound around a vertical shaft at one end or unwound from the vertical shaft by tension applied to both ends in a horizontal direction; a mesh filter support member overlapping one surface of the filter sheet; and an upper bonding strap arranged in a horizontal direction along an upper edge of the filter sheet and formed by bonding the filter support and an upper end of the filter sheet to each other, wherein the upper bonding strap is seated on an upper end of a fixed support located between both ends of the filter sheet to prevent sagging.

The filter sheet and the filter support may be connected only by the upper joint strap, and the fixed support may pass through a space between the filter sheet and the filter support without the upper joint strap.

The fixed support may include a horizontal guide wire parallel to the upper joint strap and a plurality of support legs extending vertically downward of the horizontal guide wire.

The horizontally wound-type filter may further include a mesh-like auxiliary filter support body, between the filter sheet and the filter support body, in close contact with and overlapping the surface of the filter sheet.

The auxiliary filter support and the filter support may have different mesh sizes.

The auxiliary filter support and the filter support may be disposed side by side on both sides of the fixed support with the same width.

The horizontally wound filter may further include a guide strap interposed between the auxiliary filter support and the filter support, the upper end of which is inserted into the upper junction strap, and the lower end of which protrudes from the lower end of the upper junction strap.

The guide strap supports the side of the fixed support with the surface of the lower end, and the upper junction strap may contact the upper end of the fixed support with the side of the lower end.

The horizontally wound-type filter may further include at least one joint portion for bonding the auxiliary filter support and a portion of the filter sheet other than the upper joint strap to each other.

The auxiliary filter support and the filter support may be formed of glass fibers as a material.

The upper junction strap may be formed of a bar wire connecting the auxiliary filter support, the filter support, and the filter sheet.

According to the present invention, the sheet-type filter can be easily used by spreading it in a horizontal direction without sagging. Therefore, it is possible to more effectively purify high-concentration and large-capacity exhaust gases with the wide surface of the sheet-type filter. In addition, since sagging of the filter is prevented, the dust collecting area can be widely expanded and used compared to the prior art. In addition, sagging is prevented even when the filter is wound or unwound in the horizontal direction, so it is advantageous for quick replacement and regeneration of worn parts, and wrinkles are eliminated when the filter is wound, so it is suitable for storing and replacing the filter in a roll form. Also, for the same reason, the operation of winding or unwinding the filter can be performed accurately and conveniently without malfunction.

Advantages and features of the present invention and methods for achieving them will become clear with reference to the detailed description of the following embodiments in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be implemented in various different forms, and only the present embodiments make the disclosure of the present invention complete and have ordinary knowledge in the art to which the present invention belongs. It is provided to fully inform the scope of the design, and the present invention is only defined by the claims. Like reference numerals designate like elements throughout the specification.

In the present specification, 'joining' means a coupling method in which two or more members having faces face each other and are coupled to each other, and such 'joining' includes 'intermediate bonding' in which two or more members are coupled with a medium having a face in between.

Also, a 'horizontal winding type filter' means a filter that can be wound in a horizontal direction. In this case, the horizontal direction may be a direction perpendicular to the vertical axis, and the vertical axis may be an axis perpendicular to the ground (eg, gravity direction).

Hereinafter, a horizontally wound filter according to the present invention will be described in detail with reference to FIGS. 1 to 5.

FIG. 1 is a perspective view and A-A' cross section of a horizontally wound filter according to an embodiment of the present invention, and FIG. 2 is an exploded view of the horizontally wound filter of FIG. 1 .

Referring to FIGS. 1 and 2 , in the horizontally wound-up filter 1 according to the present invention, the filter support 300 is disposed to overlap one surface of the filter sheet 100 (see the exploded view of FIG. 2 ).

Since only the upper ends of the filter sheet 100 and the filter support 300 are joined in the horizontal direction and the lower ends are separated from each other, the fixed support (a) can be inserted into the space between the two. Therefore, the upper joint (upper joint strap 400) is seated on the fixed support (a) to prevent the filter from sagging.

In addition, the upper junction part (upper junction strap 400) extends in the horizontal direction, which is the direction in which the filter is wound or unwinded, so that the filter arrangement is maintained in the horizontal direction, the movement direction is guided, and the fixed support (a) Increases the contact area between the filter and effectively transfers the load of the filter to the support side.

The horizontally wound filter 1 of the present invention is configured as follows. The horizontally wound filter 1 includes a filter sheet 100 wound around a vertical shaft (see 110 in FIG. 1 ) or unwound from the vertical shaft 110 at one end by tension applied in the horizontal direction at both ends, a filter support 300 in a mesh structure superimposed on one surface of the filter sheet 100, and arranged in the horizontal direction along the upper edge 101 of the filter sheet 100, the filter support 300 ) and an upper joint strap (see 400 in FIGS. 1 and 2 ) formed by bonding the top of the filter sheet 100 to each other, and the top joint strap 400 is seated on the top of the fixed support (a) located between both ends of the filter sheet 100 to prevent sagging.

In one embodiment of the present invention, the horizontally wound type filter 1 may be formed in a form in which the auxiliary filter support 200 and/or the guide strap 500 are interposed between the filter support 300 and the filter sheet 100. That is, the filter sheet 100 and the filter support 300 may be formed in an intermediary bonded structure via a portion of each of the auxiliary filter support 200 and/or the guide strap 500.

For example, in one embodiment of the present invention, the horizontally wound filter 1 is interposed between the filter sheet 100 and the filter support 300, the mesh-like auxiliary filter support 200 closely adhered to and overlapping the surface of the filter sheet 100, and the auxiliary filter support 200 and the filter support 300, so that the upper end is inserted inside the upper joint strap 400, and the lower end is inserted into the upper joint strap ( 400) may further include a guide strap 500 protruding from the bottom (see Fig. 2 exploded view).

Although this embodiment is described based on this embodiment, the present invention is not limited thereto, and in other embodiments, the filter sheet 100 and the filter support 300 may be directly bonded without an intermediary.

Hereinafter, the configuration and operational effects of the present invention will be described in more detail with reference to FIGS. 1 to 3 based on one embodiment of the present invention. 3 is a side view of the horizontally wound filter of FIG. 1;

In the horizontally wound type filter 1, the filter sheet 100, the auxiliary filter support 200, and the filter support 300 are overlapped with each other to be wound around the vertical shaft 110 or released from the vertical shaft 110. Refer to the perspective view of FIG. 1 (a) and the side view of FIG. 3 for the structure and appearance of the filter wound around the vertical shaft 110, and the cross-sectional view of FIG. 1 (b) and the exploded view of FIG.

As shown in FIGS. 1(a) and 3 , the filter sheet 100 is horizontally unwound (unwound) from the vertical shaft 110 or horizontally wound (rolled) around the vertical shaft 110 . This action is possible by the tension applied to both ends of the filter sheet 100 in the horizontal direction. Tension applied to the filter sheet 100 may be provided from both sides of the vertical shaft 110 at one end and a fixing part (not shown) disposed at the other end.

Since the filter sheet 100 may extend as long as desired in the horizontal direction, only a portion thereof is shown in the drawings. At the other end of the filter sheet 100 (not shown), a fixing portion formed along the same axis as the vertical axis 110 may be disposed to fix the filter sheet 100 and provide tension. Both the vertical shaft 110 and the fixing part at the other end may be formed in a substantial shaft structure, and may be arranged in a direction perpendicular to the ground to wind the filter sheet 100 around the shaft in a horizontal direction or unwind the filter sheet 100 from the shaft.

The filter sheet 100 may be provided in a form connected to the vertical shaft 110 at one end. For example, the entire horizontally wound filter 1 including the filter sheet 100, the auxiliary filter support 200, and the filter support 300 overlapping the filter sheet 100 on the vertical shaft 110 is wound in a roll form and supplied, and when in use, the other end of the filter sheet 100 may be unscrewed and connected to a fixing part that is another axis before use. At this time, the fixing part may be a rotating shaft, and the horizontal winding type filter 1 may be used in a manner in which the fixing part is rotated and wound.

The filter sheet 100 may be made of a porous material in which fine pores are formed. The filter sheet 100 may be formed of a single material or a combination of two or more materials. The filter sheet 100 may be manufactured in a sheet form, such as, for example, a nonwoven fabric, or may be used in a sheet form that is easy to process. The filter sheet 100 may be formed in a rectangular sheet shape when unfolded and may be made of various materials capable of collecting and removing contaminant particles.

The auxiliary filter support 200 is positioned between the filter sheet 100 and the filter support 300, but adheres to the surface of the filter sheet 100. Therefore, it is safe to view it substantially integrally with the filter sheet 100. When the auxiliary filter support 200 is formed, the fixed support (a) passes through the space between the auxiliary filter support 200 and the filter support 300 among the spaces between the filter sheet 100 and the filter support 300.

The auxiliary filter support 200 adheres to and overlaps the surface of the filter sheet 100 . 1 (b) and 2, the auxiliary filter support 200 overlaps one side of the filter sheet 100 in a state of close contact. The horizontally wound filter 1 includes at least one junction 600 for bonding the auxiliary filter support 200 and a portion of the filter sheet 100 other than the upper joint strap 400 to each other, so that the auxiliary filter support 200 and the filter sheet 100 can be tightly adhered to each other.

The auxiliary filter support 200 and the filter sheet 100 may be kept in close contact with each other by one or more junctions 600 formed at different positions from the upper junction strap 400 in addition to the upper junction strap 400 described later. The joint portion 600 may be formed by connecting the auxiliary filter support body 200 and the filter sheet 100 in a rod method, and for example, the joint portion 600 for bonding the lower ends of the auxiliary filter support body 200 and the filter sheet 100 to each other. However, if necessary, the auxiliary filter support 200 and the filter sheet 100 may be fixed so that they do not fall apart by arranging the bonding portion 600 at a location other than the lower end.

The filter support 300 overlaps one surface of the filter sheet 100, and the overlapping surface is the same as the overlapping surface of the auxiliary filter support 200. Therefore, the auxiliary filter support 200 and the filter support 300 can be seen as being overlapped in a double layer on one side of the filter sheet 100 . However, the filter support 300 is connected to the filter sheet 100 only by the upper junction strap 400, and the remaining parts are spaced apart, and the auxiliary filter support 200 in close contact with the surface of the filter sheet 100 is also connected to the upper junction strap 400 and the remaining parts are spaced apart.

That is, both the filter support 300 and the auxiliary filter support 200 are located on one side of the filter sheet 100 and overlap on the same side, and only the upper ends are bonded to each other. The filter sheet 100, the auxiliary filter support 200, and the filter support 300 are connected only by an upper junction strap 400 described later, and the auxiliary filter support 200 is in close contact with the surface of the filter sheet 100, so that the remaining parts of the auxiliary filter support 200 and the filter support 300 are separable from each other. Therefore, the fixed support (a) can pass through the space between the auxiliary filter support 200 and the filter support 300 without the upper joint strap 400 (see FIG. 1 (b)).

The auxiliary filter support 200 and the filter support 300 may be directly bonded, but may also be bonded through the guide strap 500 as in the present embodiment. By inserting a part of the guide strap 500 between the two, the supporting force for supporting the two filter supports and the bonding strength between the filter supports may be increased. The guide strap 500 will be described in more detail below.

Both the auxiliary filter support 200 and the filter support 300 are formed in a network structure. As shown in FIG. 2, the auxiliary filter support 200 and the filter support 300 may be formed of a mesh (net shape) structure in which, for example, the first meshes 211 and 311 and the second meshes 212 and 312 intersect to form a mesh. Due to the network structure, the fluid (which may be a fluid to be treated such as exhaust gas) passes between the filter supports and smoothly reaches the filter sheet 100 .

When the auxiliary filter support 200 and the filter support 200 are formed together, the mesh size of the auxiliary filter support 200 and the filter support 300 may be different from each other. That is, at this time, the filter support is composed of a plurality of cells (mesh) forming a network, and the cells (network) may be formed in various shapes. Preferably, square-shaped cells (mesh) may be used.

In order to reduce the pressure load of the exhaust gas applied to the filter, the mesh size of one of the auxiliary filter supporter 200 and the filter supporter 300 may be larger than that of the other one. It is possible to minimize the decrease in ventilation of exhaust gas by creating a flow space due to the size difference of the mesh.

The auxiliary filter support 200 and the filter support 300 may be formed of the same material. The auxiliary filter support 200 and the filter support 300 may be formed by crossing fibers of a material having relatively high hardness. For example, the auxiliary filter support 200 and the filter support 300 may be formed of glass fibers or may be a network structure made of glass fibers. As such a support is overlapped single or double on the surface of the filter sheet 100, sagging of the filter sheet 100 is primarily prevented.

The upper joint strap 400 is formed along the upper side 101 of the filter sheet 100. Since the upper side 101 is arranged in a horizontal direction along the extension direction of the filter sheet 100, the upper joint strap 400 is also arranged in a horizontal direction. The upper bonding strap 400 is arranged in a horizontal direction along the upper edge 101 of the filter sheet 100, and is formed by bonding the filter support 300 and the upper end of the filter sheet 100 to each other. When the auxiliary filter support 200 is in close contact with the filter sheet 100 as in the present embodiment, the upper joint strap 400 is formed by bonding the top of the filter support 300, the auxiliary filter support 200, and the filter sheet 100 to each other. For example, as shown in FIG. 1, the upper joint strap 400 may be formed as a joint body extending in a horizontal direction along the upper side 101 and having a constant width.

The upper junction strap 400 may also be formed in a bar method like the junction 600 described above. For example, the upper junction strap 400 may be formed of a bar (see 410 in FIGS. 1 (b) and 2) connecting the auxiliary filter support 200, the filter support 300, and the filter sheet 100. At least one pair of bar wires 410 may be arranged side by side in a horizontal direction to form a bonding area. The width of the upper bonding strap 400 may also be changed by the vertical interval of the bar 410. If necessary, additional bar lines may be formed between the shown bar lines 410 . The upper joint strap 400 can be deformed in a manner such as using a combination of an adhesive structure using an adhesive material in addition to the bar 410 as needed.

The upper end of the guide strap 500 (see 510 in FIG. 1 (b)) is interposed between the auxiliary filter support 200 and the filter support 300 to mediate the coupling of the two filter supports. Each filter support having a network structure can be more firmly bonded to each other via the upper end 510 of the guide strap 500 whose surface is filled. Guide strap 500, for example, may be formed of the same material as the filter sheet 100 and may have the same length as the upper joint strap 400.

Due to this, the upper junction strap 400 of this embodiment can be formed by combining the following detailed structures. 2, the upper junction strap 400 includes a filter-side junction 401 extending along the upper edge 101 at the top of the filter sheet 100, an auxiliary support-side junction 402 formed correspondingly at the top of the auxiliary filter support 200, a support-side junction 403 formed correspondingly at the top of the filter support 300, and an auxiliary support side at the upper end of the guide strap 510. The entire guide strap junction 404 formed to correspond to the junction 402 and the support side junction 403 may be formed as a multi-joint structure in the form of a strap joined to each other.

In this way, since the plurality of members are joined in multiple and tightly coupled, the load of the filter can be supported without any problem by the upper joint strap 400. In addition, since the coupling structure using the bar 410, since the upper bonding strap 400 has flexibility, even when the filter is wound around the vertical shaft 110, the entire filter can be easily transformed into a roll shape.

The lower end of the guide strap 500 (see 520 in FIG. 1 (b)) protrudes from the lower part of the upper joint strap 400. The lower end 520 of the upper junction strap 400 is exposed to the lower space of the upper junction strap 400 in a kind of free end form. In the guide strap 500, the upper end 510 is inserted inside the upper joint strap 400 to serve as a reinforcing structure, and the lower end 520 is closely adhered to the side of the fixed support (a) to serve as a guide structure.

The relationship between the fixed support (a) and the horizontally wound type filter (1) will be described in more detail. The fixed support (a) passes through the space between the filter sheet 100 and the filter support 300 without the upper joint strap 400 as shown in FIG. In this embodiment, since the auxiliary filter support 200 is in close contact with the surface of the filter sheet 100, the fixed support (a) passes through the space between the auxiliary filter support 200 and the filter support 300 among the spaces between the filter sheet 100 and the filter support 300.

As described above, since the filter sheet 100, the auxiliary filter support 200, and the filter support 300 are connected only by the upper joint strap 400, and the auxiliary filter support 200 adheres to the surface of the filter sheet 100, in particular, the lower portion of the upper joint strap 400 between the auxiliary filter support 200 and the filter support 300 is freely spaced from each other. Due to this, the fixed support (a) is inserted into the space between the auxiliary filter support 200 and the filter support 300, as shown in FIG.

The fixed support (a) is located between both ends of the filter sheet 100 in the horizontal direction. A fixed support (a) having an appropriate length may be disposed corresponding to the length of the filter sheet 100 spread in the horizontal direction. As shown in FIG. 2, the fixed support (a) may include a horizontal guide wire (a1) parallel to the upper junction strap 400 and a plurality of support legs (a2) extending vertically downward of the horizontal guide wire (a1). The fixed support (a) is formed of a material that is relatively stronger than the filter, such as a metal material, and is formed in a shape such as a narrow wire so as not to interfere with fluid flow.

Horizontal guide wire (a1), for example, may be formed by arranging a metal wire in the horizontal direction. In addition, the support leg (a2) may be formed by arranging the metal wire in the vertical direction. The horizontal guide wire (a1) and the support leg (a2) may be formed by bending a single wire, or may be formed by combining at least some of them by welding or the like.

The fixed support (a) may be disposed inside a passage through which exhaust gas flows, such as, for example, a chimney of a thermal power plant. The position is selected by fixing the support leg (a2), and both ends of the horizontal winding type filter (1) are spread horizontally to the left and right of the fixed support (a), and the horizontal guide wire (a1) at the top of the fixed support (a). The upper joint strap 400 can be seated. In such a state, the fixed support (a) is inserted between the auxiliary filter support 200 and the filter support 300, as shown in FIG.

At this time, the guide strap 500 supports the side of the fixed support (a) with the surface of the lower end 520, and the upper joint strap 400 is in contact with the upper end of the fixed support (a) as the side of the lower end (ie, the top of the horizontal guide wire (a1)) and (in an erected state).

That is, since the upper junction strap 400 is formed at the top of the filter, by the load of the structures extending to the lower part of the upper junction strap 400, the upper junction strap 400 is at the top of the fixed support (a) It can be seated in the vertical direction. Due to this, the upper junction strap 400 is in contact with the horizontal guide wire (a1) to the side of the lower end. Since the upper joint strap 400 protrudes from the lower guide strap 500 supports the side of the fixed support (a) as a surface, a double support structure of the upper joint strap 400 and the guide strap 500 is formed. Therefore, the filter can be more stably supported on the fixed support (a).

Guide strap 500 may support the side of the fixed support (a) to one side of the lower end (520). The lower end 520 of the guide strap 500 is inserted between the auxiliary filter support 200 and the fixed support (a) or between the filter support 300 and the fixed support (a) to prevent direct contact between the fixed support (a) and any one filter support. Although not shown, it is also possible to form a plurality of guide straps 500 or to form the lower end 520 of the guide strap 500 in a double structure to prevent direct contact between the fixed support (a) and the auxiliary filter support 200 and between the fixed support (a) and the filter support 300 by interposing the lower end 520 of the guide strap 500 on both sides between the fixed support (a) and the filter support 300.

The auxiliary filter support 200 and the filter support 300 are arranged side by side on both sides of the fixed support (a) with the same width as shown in FIG. 1 (b). At this time, since the width corresponds to the width in the vertical direction, the lengths of the auxiliary filter support 200 and the filter support 300 extending downward from the upper junction strap 400 are substantially the same. If the widths of the auxiliary filter support 200 and the filter support 300 are formed asymmetrically, unnecessary wrinkles may occur when wound around the vertical shaft 110, so the width of the auxiliary filter support 200 and the filter support 300 is preferably the same. In addition, since the auxiliary filter support 200 and the filter support 300 having the same width equally distribute the load on both sides of the upper joint strap 400, the upper joint strap 400 is installed on the top of the fixed support (a). It is also advantageous to seat.

Such a horizontally wound filter 1 can be used in the following manner. Hereinafter, a usage example of the filter will be described with reference to FIGS. 4 and 5 .

4 and 5 are state diagrams of the horizontally wound filter of FIG. 1 in use. In FIG. 4, a side view of the horizontally wound filter and a BB' cross-sectional view thereof are shown together.

As described above, the horizontally wound filter 1 may be provided by being wound around the vertical shaft 110 in a roll form. The vertical axis 110 shown in (a) of FIG. 4 may be in a state in which at least one of an upper end and a lower end is coupled to a driving shaft (not shown). Therefore, when the vertical shaft 110 is rotated by the driving of the driving shaft (of course, it can also be rotated manually), the other end is released from the vertical shaft 110.

At this time, by passing the horizontally wound type filter 1 across the fixed support (a), the upper bonding strap 400 can be naturally seated on the top of the fixed support (a). As shown in the cross section of FIG. 4 (b), among the filter sheet 100 and the filter support 300, the fixed support (a) is inserted into the space between the auxiliary filter support 200 and the filter support 300, and the upper joint strap 400 can be supported by the horizontal guide wire (a1) of the fixed support (a). In this state, when the other end is pulled out to the fixing part on the opposite side (which may be the same shaft structure as the vertical shaft 110 as described above) and fixed, the entire filter is spread in the horizontal direction.

5 illustrates the horizontally wound filter 1 spread in the horizontal direction. Since the horizontally wound filter 1 has a structure in which the upper joint strap 400 is supported by the fixed support a, even if it is extended in the horizontal direction, problems caused by sagging of the upper portion are substantially eliminated. Therefore, the filter can be extended and used as long as necessary. In addition, even if the filter is wound around the vertical shaft 110 from side to side or unwound from the vertical shaft 110 as shown in FIG. 5, since there is no deflection, the problem of wrinkles while winding around the shaft is effectively solved.

Therefore, since the horizontally wound filter 1 of the present invention can treat a fluid containing pollutants on a wider surface, the present invention can be applied to a wide passage structure through which high concentration exhaust gas passes, such as inside a chimney of a thermal power plant. By applying the present invention, the pollutant treatment rate can be improved. In addition, since the operation of winding or unwinding the filter in the form of a roll is very smooth, it is possible to quickly replace the exhausted filter and further improve processing efficiency.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may be implemented in other specific forms without changing the technical spirit or essential features of the present invention. It will be understood that it can be implemented. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.
