Description

Filter with support>

The present invention relates to a filter, and more particularly to a filter formed with a support.

The filter is installed in the fluid flow path to filter contaminants. The filter can be applied to various kinds of fluids and accordingly, various materials and kinds are formed. For example, a filter made of a breathable fabric or the like can be used to treat the pollutants of the exhaust gas generated in an industrial facility.

The filter is made in consideration of various parameters such as density, concentration, flow rate, flow rate of the fluid to be treated such as exhaust gas, back pressure and pressure loss on the filter. In addition, the installation location and application location are selected as suitable places considering these. Nevertheless, depending on the flow state of the fluid, back pressure may increase or the pressure distribution may change.

If this situation persists, the filter may increase the risk of breakage and may be difficult to maintain its shape. Furthermore, since the filter made of cloth or the like is difficult to maintain its shape by pressure, it may be difficult to exhibit its performance properly. Attempts have been made to solve this problem (e.g., Korean Patent Registration No. 10-1458279, etc.) by using a separate support structure such as a conventional frame.

However, in such a case, there arises a problem that the installation area and the installation structure of the filter are severely restricted. Even if there is a support structure, only a part of the filter in contact with the filter enhances the supporting force. It was difficult. Further, since a separate supporting structure is required, there is a problem that it is very difficult to smoothly apply a filter to a large flow path having a large installation space. Therefore, more effective improvement measures are required.

Fig. 4 is a cross- It is a perspective.

Referring to Figs. 1 to 4, a filter 1 formed with a support according to an embodiment of the present invention includes a filter sheet 10 and a support 20 superimposed and fixed to the filter sheet 10. The support 20 is in the form of a lattice and the lattice shape is formed by at least two wire shapes (see FIG. 2 and FIG. 3) and a second wire portion And members are formed so as to cross each other. The second wire portion 22 is passed between the first wire portions 21 and is arranged in the longitudinal direction of the filter sheet 10 So that the tension of the filter sheet 10 that is wound around the shaft in the longitudinal direction or wound on the shaft can be transmitted and dispersed very effectively. Further, the second wire portion 22 is tensed by the transmitted tension and the tight contact with the first wire portion 21 is strengthened, so that the support force of the support body 20 can be suitably increased corresponding to the tension have.

In addition to the first wire portion 21 and the second wire portion 22, the first wire portion 22 and the second wire portion 22 are arranged in the same direction as the second wire portion 22, The supporting force of the supporting body 20 can be further strengthened by the wire portion (refer to FIG. 2 and FIG. 3) and the structure of the extended supporting body 30 extending from the supporting body 20 to the outside of the filter sheet 10 , It is possible to more conveniently replace and install the filter 1 on which the support is formed, as well as to maximize the usable filter area. Further, by using the structure of the expanded support 30, the back pressure acting on the bar filter, which can be fixed firmly by positioning the filter connection portion on the extended support 30 and winding it around the shaft (see 40 in FIG. 4) It is possible to effectively solve problems such as concentration. Preferably, the filter 1 formed with the support of the present invention can be applied to the treatment of exhaust gas generated by the combustion of fuel or the like, and can withstand the back pressure of such exhaust gas and is highly effective in collecting and treating pollutants in the exhaust gas Lt; / RTI >

The filter 1 having such a support of the present invention is constituted as follows. The support-formed filter 1 comprises a porous filter sheet 10 wound around a shaft or wound in a longitudinal direction on the shaft (see 40 in FIG. 4), and a filter sheet 10 arranged in the width direction of the filter sheet 10, A plurality of first wire portions 21 arranged in the longitudinal direction of the filter sheet 10 and spaced apart from each other and passing between at least a pair of adjacent first wire portions 21 and intersecting with the first wire portions 21; A plurality of second wire portions 22 and a plurality of vent holes 24 formed between the intersections of the first wire portions 21 and the second wire portions 22 spaced from each other, And a lattice-shaped support 20 superimposed on the substrate 10. According to one embodiment of the present invention, the filter 1 on which the support is formed further includes an extended support 30 which extends from the support 20 to the outside of the filter sheet 10 and does not overlap with the filter sheet 10 And the support 20 are arranged in the longitudinal direction of the filter sheet 10 and spaced apart from each other so as to stagger between the at least a pair of adjacent first wire portions 21 and the second wire portion 22, And a plurality of third wire portions 23 intersecting the first wire portion 21 on the opposite side of the second wire portion 22. Hereinafter, the filter 1 formed with the support according to one embodiment of the present invention will be described in detail with reference to the drawings.

The filter sheet 10 may be formed in the form of a sheet extending relatively long in one direction. Such a filter sheet 10 can be wound around an axis (see 40 in FIG. 4) or can be used from an axis 40 in one relatively elongated direction and can be used in such a manner that the direction in which the shaft 40 is wound or unwound Can be defined in the longitudinal direction. The direction perpendicular to the longitudinal direction can be defined as the width direction. For example, the transverse direction of FIGS. 6 to 9 may be the longitudinal direction of the filter sheet 10, and the longitudinal direction perpendicular thereto may be the transverse direction. The filter sheet 10 may be made of a porous material, for example, a nonwoven fabric. The porous filter sheet 10 can be used to collect and filter pollutants in the fluid. The filter sheet 10 may be formed in a square shape, and the length, width, and the like may be appropriately changed depending on the installation place, the applicable equipment, and the like.

The support 20 overlaps with this filter sheet 10. That is, as shown in FIG. 1 (b), a portion of the filter sheet 10, which overlaps the filter sheet 10 and supports the filter sheet 10, forms the support 20. The support 20 includes at least two wire-like members arranged in different directions, which are crossed to form a lattice. 2, a plurality of first wire portions 21 are spaced apart from each other and arranged in a width direction of the filter sheet 10, and a plurality of second wire portions 22 are spaced apart from each other to form a filter sheet 10, As shown in Fig. The direction in which the second wire portions 22 of FIG. 2 are arranged corresponds to the longitudinal direction of the filter sheet 10 described above and the direction in which the second wire portions 22 are wound or unwound on the shaft 40. The ventilation openings 24 are formed as empty spaces formed between the intersections of the first wire portions 21 and the second wire portions 22 spaced from each other. The third wire portions 23 are arranged in the longitudinal direction of the filter sheet 10 and spaced apart from each other like the second wire portions 22 so that the gap between the at least a pair of adjacent first wire portions 21 is the second wire portion 21. [ (22). As a result, as shown in FIG. 3, the first wire portion 21 and the second wire portion 22 can be crossed with each other. Structural features and effects of these will be described in more detail below.

The tensile strength of the second wire portion 22 of the support 20 may be greater than the tensile strength of the first wire portion 21. [ That is, the second wire portion 22 is more resistant to the deformation force than the first wire portion 21, such that it can support the filter sheet 10 more firmly. The tensile force may be a tension applied to the entire filter, and in particular, a tensile force applied in the longitudinal direction of the filter sheet 10. [ As will be described later, the second wire portion 22 can more effectively transmit and receive such a tensile force, and the tensile strength can be made larger. The first wire portion 21 is arranged to cross the second wire portion 22 to form a lattice structure and supports the filter sheet 10 in a direction different from that of the first wire portion 21, It is possible to effectively maintain the shape of the lens.

Here, the tensile strength may be, for example, the maximum tensile strength, which may be, for example, the maximum load that the wire endures during the tensile force until the wire breaks in the longitudinal direction with respect to each wire portion, It may be measured separately. The third wire portion 23 may have a tensile strength larger than that of the first wire portion 21 similarly to the second wire portion 22 when the third wire portion 23 is formed as in the present embodiment, The tensile strength of the second extension wire portion 32 and the third extension wire portion 33 constituting the extended support 30 described later can be made larger than the tensile strength of the first extension wire portion 31 .

The extended support 30 is formed so as not to overlap with the filter sheet 10 by extending outwardly of the filter sheet 10 as shown in Fig. That is, the extended support 30 is connected to the support 20, but has a structure extended to the outside of the filter sheet 10 without overlapping with the filter sheet 10. The extended support 30 is disposed in the direction in which the filter sheet 10 outside the filter sheet 10 is wound or unwound on the shaft 40 Or at both ends. That is, the extended support 30 can be disposed on one side or both sides of the end of the filter sheet 10 along the longitudinal direction thereof. The extended support 30 may be formed separately from the support 20 and then coupled to the support 20. However, the extended support 30 may be integrally formed with the support 20 as in the present embodiment. The support 20 may include glass fiber, and the extended support 30 may include glass fiber. However, it is not limited thereto, and it is also possible to form the expanded support 30 with other materials and / or other structures. When the supporting body 20 and the extended supporting body 30 are integrally formed as in the present embodiment, unnecessary joining portions and connecting portions are not formed between the supporting body 20 and the extended supporting body 30, It can have an advantage that it can endure. That is, the supporting body 20 and the extended supporting body 30 are integrally formed with the same structure, and the portion superimposed on the filter sheet 10 can be composed of the supporting body 20 and extended to the outside of the filter sheet 10 The portion that does not overlap with the filter sheet 10 can be composed of the expanded support 30. In the present embodiment, such a structure will be mainly described.

The extended support 30 is connected to the support 20 and receives a tensile force. At least a portion of the support 20 may be sewn and fixed to the filter sheet 10 and the expanded support 30 may be connected to the support 20. The support member 20 and the filter sheet 10 may be fixed to each other by forming a bar member (see FIG. 1 and FIG. 2) to fix the extended support member 30 connected to the support member 20 . In particular, through a coupling structure in which fluidity is imparted between the filter sheet 10 and the support body 20 by a bar method using a rod member 11 or the like, instead of a structure in which movement is blocked by a simple adhesive or the like, It is possible to realize a structure in which the support body 20 and the extended support body 30 connected thereto are entirely stretched and contracted appropriately and the supporting force is strengthened corresponding to the tension. When the extended support 30 and the support 20 are integrally formed as in the present embodiment, the extended support 30 also includes the first extension wire portion 31, the second extension wire portion 32 , And may further include a third extension wire portion 33. [ The first extension wire portion 31 is arranged in the above-mentioned width direction and the second extension wire portion 32 and the third extension wire portion 33 are arranged in the longitudinal direction described above and intersected with each other. A plurality of ventilation holes 34 may be formed. The first extension wire portion 31 may be arranged in the same shape outside the filter sheet 10 in substantially the same structure as the first wire portion 21 and the second extension wire portion 32 may be arranged in the same shape, And the third extension wire portion 33 may also be arranged in the same manner on the outside of the filter sheet 10 in substantially the same structure as the second wire portion 22 and the third wire portion 23, respectively. The second extension wire portion 32 may be formed by extending the second wire portion 22 outside the filter sheet 10 and the third extension wire portion 33 may be formed by the third wire portion 23, Or may extend outwardly from the sheet 10 as it is.

2 to 4, the structure and specific effects and the like of the support 20 will be described in more detail. As described above, in the present embodiment, the extended support 30 is substantially the same as the structure of the support 20, so that the description of the structure of the extended support 30 will be omitted as a description of the support 20 do. That is, the structure and the effect of the first wire portion 21, the second wire portion 22, and the third wire portion 23, which will be described later, are the same as those of the first extension wire portion 31, The third extension wire portion 32, and the third extension wire portion 33, respectively.

The first wire portions 21 are arranged in the width direction of the filter sheet 10 and are spaced apart from each other. The first wire portions 21 may be spaced apart from each other by a predetermined distance and may be relatively thicker than the second wire portions 22 and the third wire portions 23. [ The second wire portions 22 are arranged in the longitudinal direction of the filter sheet 10 and are spaced apart from each other. The second wire portion 22 passes particularly between at least a pair of adjacent first wire portions 21 and intersects with the first wire portion 21. That is, as shown in FIG. 2 and FIG. 3 (a), a structure is formed in which the second wire portions 22 repeatedly pass between the first wire portions 21 arranged at regular intervals apart from each other.

The third wire portions 23 are arranged in the longitudinal direction of the filter sheet 10 and are spaced apart from each other like the second wire portions 22. Particularly, the third wire portion 23 passes between the at least a pair of adjacent first wire portions 21 and staggeredly passes through the second wire portion 22, And intersects with the wire portion 21. That is, as shown in FIG. 2 and FIG. 3 (a), the second wire portion 22 and the third wire portion 23 are staggered between the first wire portions 21 arranged at regular intervals apart from each other The second wire portion 22 and the third wire portion 23 are brought into close contact with the opposite sides of the first wire portions 21 and can apply pressure to each other in opposite directions. The second wire portion and the third wire portion 23 have mutual close contact portions 201 formed between the intersections intersecting the first wire portions 21 as shown in Figs. 2 and 3 (a) The first wire portion 21 and the second wire portion 21 are separated from each other and are separated from each other in the pressure contact portion 202 while being closely contacted with each other in the mutual contact portion 201, The opposite sides of the first wire portions 21 can be held in close contact with each other. This makes it possible to form a very rigid support structure due to friction between the wire parts. Further, by using the arrangement interval of the first wire portions 21 and the interval between the second wire portions 22 and the third wire portions 23, the ventilation holes 24 having a sufficient area for smoothly flowing the fluid are assured can do.

Since the second wire portion 22 and the third wire portion 23 extend in the longitudinal direction in which the tension is transmitted when the filter sheet 10 is wound around the shaft (refer to 40 in Fig. 4) or withdrawn from the shaft, The tensile force that can be applied to the sheet 10 in the corresponding direction is received and can be more effectively absorbed and dispersed. That is, as shown in Fig. 4, the longitudinal tension component in the direction in which the filter 1 with the support formed thereon is wound or unwound in the state of being connected to the shaft 40 is the same as that of the second wire portion 22 and Fig. It is transmitted to the third wire portion 23 and can be more effectively dispersed. The second extension wire portion 32 and the third extension wire portion 33 are also connected to the bar support body 20 in the same longitudinal direction as the second wire portion 22 and the third wire portion 23, And the entirety of the extended support 30, the tensile force component in the corresponding direction can be more effectively dispersed and dissolved.

In addition, when the tension is transmitted in this way, the second wire portion 22 and the third wire portion 23 are tense due to the tension, so that the first wire portions 21 can be closely contacted with each other and pressurized, Since the second wire portion 22 and the third wire portion 23 are closely contacted with each other, the supporting force of the entire supporting body 20 is greatly enhanced by the increased friction between the wire portions. That is, when the back pressure is increased by the flow of the fluid to be treated such as exhaust gas, the tensile force is increased. Such tension is transmitted to the support 20 to relieve the pressure of the filter sheet 10, ) Can be obtained a rather complex synergistic effect. That is, the structure of the support 20 using a plurality of wire portions crossed to each other so as to allow mutual flow, rather than simply a fixed grid structure, can impart a very improved supporting force to the filter.

The support 20 may include planes 21a, 22a and 23a on the surface facing the filter sheet 10 as shown in Figures 3 (a) and 3 (b) The structure in which the sheet 10 is closely contacted can be realized. In particular, the first wire portion 21 and the second wire portion 22 each include a plurality of planes 21a, 21b, 22a, and 22b on the surface thereof, as shown in FIG. 3, so that the cross- ≪ / RTI > The third wire portion 23 may also include a plurality of planes 23a and 23b on its surface so that the first wire portion 21 and the second wire portion 22 have the same cross-sectional shape. As a result, not only the degree of close contact between the support 20 and the filter sheet 10 but also the degree of close contact between the wire portions can be greatly increased. Therefore, it is possible to realize a more improved support structure with the increased frictional force as described above.

On the other hand, the expanded support 30 is connected to the support 20 and extends outwardly of the filter sheet 10. As described above, the structural features of the support 20 in the present embodiment are equally applicable to the extended support 30, and the extended support 30 can also form a very rigid support structure as described above. In particular, the expanded support 30 may extend outwardly of the filter sheet 10 and be disposed in the longitudinal direction described above. That is, by using a structure in which the extended support 30 is extended and arranged in the longitudinal direction in which the filter sheet 10 is wound or unwound as shown in Fig. 4, It can be conveniently exchanged and installed, and the usable filter area can be maximized. In addition, by using the structure of the extended support 30, the filter connection portion is placed on the extended support 30 and the filter 40 is caulked and fixed firmly so that the back pressure acting on the filter is concentrated on the inter- Can be prevented. The function and effect of the extended support 30 will be described later in more detail.

FIG. 5 is a view illustrating the use state of the filter of FIG. 1, and FIGS. 6 to 9 are operation diagrams showing the operation state related to replacement and relocation of the filter of FIG.

Referring to Fig. 5, the filter 1 on which the support is formed can be used while being wound around the shaft 40. Fig. It is possible to arrange the filter 1 on which the support is formed at a desired point in the fluid flow space by forming the shaft 40 at both ends of the filter and winding the both ends to the shaft 40. The exposed portion is a portion where the support 20 is superimposed on the filter sheet 10 and the filter sheet 10 as shown in FIG. May be wound on the shaft 40 and not be exposed. The fluid to be treated may be an exhaust gas containing pollutants or the like and may flow through the exposed filter sheet 10 in a direction crossing the filter (see arrows) as shown and exposed. In this state, the fluid can be passed continuously and the pollutants in the fluid can be treated. A guide block 50 is formed on the shaft 40 so as to prevent the filter from being separated during winding or winding. Although not shown, the shaft 40 can be detachably connected to a drive shaft (not shown) provided in a facility including a fluid flow space and rotated.

As described above, the filter 1 provided with the support disposed in the fluid flow space effectively dissolves the back pressure due to the fluid flow through the self-formed support 20, rather than a separate support facility, have. That is, the support structure in which the first wire portion 21, the second wire portion 22, and the third wire portion 23 intersect with each other as described above can more effectively enhance the supporting force of the filter, It can be handled easily. In particular, even if the back pressure is increased by the fluid flow and the tension of the filter is increased, the pressure of the filter sheet 10 is effectively reduced by dispersing the tension by the support 20 superimposed on the filter sheet 10 . When the tensile force is transmitted to the support 20 as described above, the second wire portion 22 and the third wire portion 23 are tightened by the tension, and the first wire portions 21 are more closely contacted with each other And the second wire portion 22 and the third wire portion 23 are more closely contacted with each other. Therefore, the supporting force of the entire supporting body 20 is reinforced by the increased friction between the wire portions. That is, the mutual contact section 201 between the second wire section 22 and the third wire section 23 is further tightened by the tensile force and the binding force is strengthened, and the press connection section 202 is also pressed by the first wire section 21 and the bonding force of the whole support body 20 can be greatly increased. Therefore, the filter 1 formed with the support of the present invention can be used very smoothly even in a bad condition such as a large fluid flow rate or a high flow rate and a high concentration. Even if tension is increased due to other reasons such as winding the filter on the shaft 40 or winding the filter on the shaft 40, the supporting body 20 can be supported on the supporting body 20 can be used to more effectively prevent breakage or the like of the filter sheet 10 and the like and to safely protect the filter.

On the other hand, the filter 1 on which the support body is formed can be exchanged and arranged more conveniently by using the extended support body 30 as described above. For example, when the process as shown in Fig. 5 is repeated to use the entire filter sheet 10 (including the portion wound around the shaft 40) up to the use limit, as shown in Fig. 6 The shaft 40 can be rotated to wind the used filter sheet 10 on one of the shafts 40. In this case, the expanded support 30 extending outwardly of the filter sheet 10 is exposed, and as shown in FIG. 7, a new filter 1-1 (a filter having a support of the present invention, Is referred to as a new filter 1-1 for the sake of convenience, can be connected to the extended support 30 so that the whole part of the other shaft 40 can be replaced with a new filter 1-1. 8, the expanded support 30-1 of the new filter 1-1 is directly connected to the expanded support 30 of the filter 1 having the previous support to form the expanded supports 30 and 30 -1), and the position of the connecting portion A can be adjusted by rotating the shaft 40. [0064] At this time, the length of the entire extended supports 30 and 30-1 connected to each other can be appropriately changed according to need, and the method of forming the connection part A is not limited to the mutual fixing between the extended supports 30 and 30-1 And may be formed in various ways such as a bar.

After the new filter 1-1 is connected in this way, the shaft 40 can be rotated to dispose the new filter 1-1 in the state shown in FIG. That is, the connection portion (see A in FIG. 8) formed on the extended support 30-1 can be wound on the shaft 40 together with the extended support 30-1 so as not to be exposed to the outside, and the filter sheet 10- 1 is superimposed and fixed on the support 20-1 connected to the extended support 30-1 so that it is not required to be wound on the shaft 40 but is directly exposed from the beginning portion thereof (see Figs. 8 and 9a) . In this way, the filter can be exchanged very conveniently by utilizing the extended support 30-1, and the new filter 1-1 can be relocated and used again for pollutant treatment. Particularly, since the exchanged new filter 1-1 can be wound around the shaft 40 via the expanded support 30-1, the portion of the filter sheet 10-1 used for the pollutant treatment is unnecessarily wound So that the filter sheet 10-1 can be exposed from its starting portion aa, as shown, and the usable area of the filter can be maximized. Also, in this state, the inter-filter connection portion (see FIG. 8A) is pressed and fixed in a state of being wound around the shaft 40 together with the extended support 30-1 without being exposed to the outside, Fatigue and stress concentration can be solved very effectively.

Hereinafter, another embodiment of the present invention will be described in detail with reference to FIG. In the following description, the same reference numerals will be given to the same elements throughout the drawings.

Fig. 10 is an enlarged perspective view showing a support of a filter on which a support is formed according to another embodiment of the present invention, and an arrangement relationship of a part of the expanded support and a filter sheet.

Referring to FIG. 10, the support-formed filter according to another embodiment of the present invention is formed in such a structure that the support 20 includes the first wire portion 21 and the second wire portion 22. That is, the support 20 may be constructed so as to include the first wire portion 21 and the second wire portion 22 without the third wire portion (refer to 23 in FIG. 2) of the above-described embodiment. Specifically, the support-formed filter according to another embodiment of the present invention includes a porous filter sheet 10 wound around a shaft in the longitudinal direction or wound around the shaft, and a filter sheet 10 arranged in the width direction of the filter sheet 10, A plurality of first wire portions 21 arranged in the longitudinal direction of the filter sheet 10 and spaced apart from each other and passing between at least a pair of adjacent first wire portions 21 and intersecting with the first wire portions 21; And a plurality of vent holes 24 formed between the intersections of the first wire portions 21 and the second wire portions 22 spaced apart from each other, And a lattice-shaped support 20 superimposed on the sheet 10.

That is, the support 20 may be formed in a lattice form in which the first wire portion 21 and the second wire portion 22 are crossed as shown in FIG. Even in such a case, the tensile strength of the second wire portion 22 may be larger than the tensile strength of the first wire portion 21 in the support 20. That is, as in the above-described embodiment, the second wire portion 22 is more resistant to the deformation force than the first wire portion 21, such as tensile force, so that it is possible to more firmly support the filter sheet 10. As described above, the tensile force may be a tension applied to the entire filter, and in particular, a tensile force applied in the longitudinal direction of the filter sheet 10. [ Therefore, the tension can be dispersed by the second wire portion 22, and the filter can be more effectively supported. The first wire portion 21 is arranged to cross the second wire portion 22 to form a lattice structure and supports the filter sheet 10 in a direction different from that of the first wire portion 21, It is possible to effectively maintain the shape of the lens.

When the support 20 includes the first wire portion 21 and the second wire portion 22 as described above, the extended support 30 may be formed in a corresponding shape. That is, the extended support 30 also has a structure including the first extension wire portion 31 and the second extension wire portion 32 and may be integrally formed with the support 20 as described above. Also, the tensile strength of the second extension wire portion 32 may be larger than the tensile strength of the first extension wire portion 31 in the extended support 30 as well.

The supporting body 20 is formed in a lattice shape, and the pressure applied to each other at intersections formed as a result of intersection of the second wire portions 22, which are constituent elements in a lattice form, between the adjacent first wire portions 21 The first wire portion 21 and the second wire portion 22 can be fixed tightly to each other. The support body 20 may be fixed to the filter sheet 10 by a bar method through the above-described bar member 11 or the like. At this time, the support member 20 may be fixed to the filter sheet 10 through the bar member 11, As a result of fixing the portion 21 and the second wire portion 22 to the filter sheet 10, the fixing force between the first wire portion 21 and the second wire portion 22 Can be strengthened. In addition, for example, a material having an adhesive force such as an adhesive may be applied to the intersection of the first wire portion 21 and the second wire portion 22, or the first wire portion 21 and the second wire portion 22 may be joined together The fixing force between the first wire portion 21 and the second wire portion 22 may be further strengthened by forming a coupling portion (not shown) formed by binding or sewing. On the other hand, the entire support body 20 can be fixed to the filter sheet 10 by the bar method through the above-mentioned bar member 11 or the like, and also, if necessary, the first wire portion 21 and / It is also possible to attach and fix the part 22 to the filter sheet 10 via a substance having an adhesive force. A filter having a support formed in this manner can be formed.
