The honeycomb filter element is formed by rolling corrugated paper, in the invention, the corrugated paper is of a double-layer corrugated paper structure and comprises wave paper 1 and plane paper 2, and the wave paper 1 is adhered to the plane paper 2 through glue, thereby forming a piece of double-layer paper with a permanent U-shaped wave structure.
For the purpose of structural description, defined herein are: wave paper 1 sets up on plain paper 2, it is ascending section 11 to begin to rise gradually to one section of crest 13 from the contact point position (this point is preceding contact point 3) of wave paper 1 and plain paper 2, one section that plain paper 2 corresponds ascending section 11 is anterior segment 21, it is descending section 12 to begin to descend gradually to one section of the next contact point position (this point is back contact point 4) of wave paper 1 and plain paper 2 from crest 13, one section that plain paper 2 corresponds descending section 12 is back segment 22, one section of wave paper 1 between two adjacent wave structures is the trough section, one section that plain paper 2 corresponds the trough section is the changeover portion.
Corrugated paper can set up a plurality of 5 points of glue dripping on plane paper 2 in the manufacture process, then puts wave paper 1 on plane paper 2 and then exerts certain pressure to it is fixed to realize pasting between wave paper 1 and plane paper 2. As the corrugated paper of filter core, its mode of pasting is comparatively complicated, specifically as follows: after the honeycomb filter core is rolled into to the corrugated paper, its one end is the inlet end, and the other end is the blind end, and one side that the corrugated paper corresponds the blind end needs to laminate completely to close the air flue that forms behind laminating wave paper 1 and plane paper 2, because wave paper 1 is the wave structure formula structure, it is not plane and plane formula paste when pasting with 2 compaction of plane paper, wave paper 1 must have the fold structure.
In the prior art, glue is dripped at the contact point (either the front contact point 3 or the rear contact point 4) on the same side of each wave structure, and then the wave paper 1 is flattened in the same direction. This type of attachment has the following problems: the former contact point 3 is used as the glue dripping 5, the glue dripping 5 is pressed and fixed in the direction from the upward slope section 11 to the downward slope section 12, the glue dripping 5 passes through the front section 21 and the rear section 22 of the plane paper 2 from the former contact point 3 in sequence under the action of pressure, when the glue dripping 5 flows under the action of pressure, the glue amount is gradually reduced along with the increase of the stroke, the condition of the wave paper 1 is completely opposite, the upward slope section 11 of the wave paper 1 has fewer folds (even the front section 21 of the plane paper 2 corresponding to the upward slope section 11 of the wave paper 1 is in plane and plane contact and pasting), the redundant paper on the wave paper 1 is accumulated in the downward slope section 12, so that the fold amount is greatly increased, the condition that the glue amount is sufficient when the front section 21 is in plane and plane contact with the plane, and the glue amount is insufficient when the rear section 22 is in plane and contact with the fold, and the condition that the adhesive amount is insufficient due to the existence of the condition, the corrugated paper has weak pressure bearing capacity, and the corrugated paper is easy to crack corresponding to the closed end.
In order to solve the problems, the novel sealing method for the air outlet end of the corrugated composite filter paper with the honeycomb filter element provided by the invention adopts a new sticking and fixing mode between the corrugated paper 1 and the plane paper 2.
In a first mode
Redesign the glue dripping point position on the plane paper 2, namely: glue dripping is carried out on the point of the plane paper 2 corresponding to each corrugation peak 13 of the wavy structure, and the glue dripping amount is unchanged (the glue dripping amount is the same as that of each existing drop). Based on the glue dripping mode, pressure is applied to two sides (the front contact point 3 and the rear contact point 4) from the ridges 13 of the wavy structure, so that the wavy paper 1 and the plane paper 2 are pasted and fixed at the closed end.
In the new pasting mode, the stroke of the glue dripping 5 is only the front section 21 (the rear section 22), compared with the existing method that the glue dripping 5 needs to pass through the front section 21 and the rear section 22, the stroke of the glue dripping 5 is reduced by half, and the consistency of the glue dripping amount in the stroke can be improved due to the reduction of the glue dripping stroke, particularly more glue dripping can be reserved at the tail part of the glue dripping stroke, so that the pasting firmness degree of the wavy paper 1 and the plane paper 2 is improved.
After redesigning the glue dripping point, a new pressing and fixing mode (or a sticking mode) is adopted for each wave structure. Not only is: the corrugated paper 1 is pressed down from the position of the crest 13 of the corrugated structure, and then pressure is uniformly applied to contact points (a front contact point 3 and a rear contact point 4) on two sides of the crest 13, so that the bonding and fixing of the corrugated paper 1 and the plane paper 2 are realized. In this new pressing and fixing mode, the ridges 13 are first pressed down, and one wave structure (large wave structure) is divided into two wave structures (small wave structures), so that the amount of paper to be compressed is reduced, that is, the degree of corrugation is reduced, and meanwhile, for an original wave structure, the corrugation is more uniform, and because the uniformity of the corrugation distribution is improved, and the uniformity of the glue amount is increased, then under the condition that the glue dropping amount is not changed, the firm adhesion degree between the wave paper 1 and the plane paper 2 is greatly improved.
Mode two
Redesign the glue dripping point position on the plane paper 2, namely: on the plane paper 2, glue dripping is carried out corresponding to two contact points (a front contact point 3 and a rear contact point 4) of each wave structure, and the glue dripping amount is reduced to one half or two thirds of the original glue dripping amount. Based on the glue dripping mode, the pressure is applied to the ridges 13 of the wave structure from the contact points on the two sides of the wave structure to press the wave paper 1 until the ridges 13 of the wave structure.
In the new pasting mode, the stroke of the glue dripping 5 is only the front section 21 (the rear section 22), compared with the existing method that the glue dripping 5 needs to pass through the front section 21 and the rear section 22, the stroke of the glue dripping 5 is reduced by half, the consistency of the glue dripping amount in the stroke can be improved due to the reduction of the glue dripping stroke, especially the tail of the glue dripping stroke at the front section is converged with the tail of the glue dripping at the rear section, so that more glue dripping 5 can be kept at the two ends, and the pasting firmness degree of the wavy paper 1 and the plane paper 2 is improved.
After redesigning the glue dripping point, a new pressing mode (or sticking mode) is adopted for each wave structure. Not only is: the wavy paper 1 is squeezed from the contact points (the front contact point 3 and the rear contact point 4) on the two sides of the wavy structure, and then pressure is uniformly applied to the ridges 13, so that the sticking of the wavy paper 1 and the plane paper 2 is realized. In the new pressing mode, the up-slope section 11 and the down-slope section 12 of the wave structure on the corrugated paper 1 are pressed down firstly, the up-slope section and the down-slope section 12 are uniformly folded to the position of the ridge 13 in the pressing process, and then the pressed corrugated paper 1 is pressed intensively at the position of the ridge 13. In the above-mentioned mode of pasting, the paper volume that uphill section 11 and downhill path 12 need be extruded is less, that is to say the fold degree can diminish, and its fold degree of consistency is higher, because the fold degree of consistency improves, the fold degree diminishes, and glue solution volume degree of consistency increases simultaneously, so under the unchangeable circumstances of glue dripping volume, the firm degree of pasting between wave paper 1 and plane paper 2 has just obtained very big degree ground improvement. In addition, after the corrugated paper 1 at the position of the crest 13 is concentrated, the front section 21 and the rear section 22 are submitted and gathered, so that sufficient glue solution can be provided for the pasting of the corrugated paper 1 at the position of the crest 13, and the pasting firmness degree between the corrugated paper 1 and the plane paper 2 can be further improved.
Mode III
The third mode is an optimization scheme of the first mode, and the difference between the third mode and the first mode is that after two small wave structures are formed by pressing down from the ridge 13, the wave crest of the small wave structure is pressed down for the second time, and then forward pressure is applied to the wave paper 1, so that four small wave structures (four small wave structures formed by pressing down the large wave structure for the second time) are extruded and deformed by the forward pressure. In this way, the corrugation degree of the wave structure is completely consistent, which is beneficial to improving the firm degree of the adhesion between the wave paper 1 and the plane paper 2. According to the third pasting mode, the glue dripping 5 mode is also changed, glue dripping is carried out on the ridges 13 of the large wave structure and the two wave crests of the small wave structure formed after one-time pressing, and the glue dripping amount can be reduced to one third or one half of the original glue dripping amount.
The corrugated composite filter paper is a front-stage process for manufacturing the honeycomb filter element, namely a filter material for manufacturing the honeycomb filter element, the air outlet end of the corrugated composite filter paper is sealed without leakage, and the corrugated composite filter paper is not damaged under certain wind resistance and is the most important technical index of the corrugated composite filter paper. The corrugated filter paper required by the honeycomb filter element is formed by compounding a layer of flat filter paper (plain paper) and a layer of filter paper (wave paper) pressed into a certain geometric shape (such as a triangle, a circle, an irregular polygon and the like), one end of the compounded corrugated filter paper is required to be closed, leakage cannot occur even under certain wind resistance, and otherwise, the quality is considered to be unqualified. The invention adopts a novel corrugated paper end sealing method, which can ensure sealing and can achieve the purpose of stronger strength of a sealing part under certain wind resistance. The core concept of the sealing method is as follows: and (3) dripping glue at the end points of the front section and/or the rear section of the plane paper, pressing the wavy paper correspondingly to the dripping glue and respectively applying pressing force along the front section and the rear section. The sealing mode has the following main characteristics: 1. the glue dripping (sealant) is flattened under the action of external force so as to ensure the effective sealing of the sealing port; 2. the direction of flattening is both sides formula and flattens, compares with the unilateral flattening method among the prior art, and among the bilateral flattening mode, the stroke length of glue dripping shortens half, and the deformation accumulation degree of wave paper when the suppression is fixed is little, and the fold distributes evenly to make to flatten the resistant windage ability of end and obtained promoting by a wide margin, just also increased the burst length, reduced sealed leakage risk.
The invention also provides corrugated composite filter paper of the honeycomb filter element, which comprises wave paper 1 and plane paper 2, wherein the wave paper 1 and the plane paper 2 are both filter paper capable of filtering gas, and the difference is that the wave paper 1 is wave paper and the plane paper 2 is plane paper.
The wave paper 1 comprises a continuous wave structure, preferably the structure of each wave structure on the wave paper 1 is the same, i.e. the height of the wave structure is the same as the wavelength of the wave structure.
For the purpose of structural description, the following are defined: the wave structure is provided with an upward slope section 11 and a downward slope section 12, a wave crest is formed by the upward slope section 11 and the downward slope section 12 along the same direction on the horizontal direction (the depth direction of the wave crest or the wave trough on the wave structure is longitudinal), a wave trough is formed by the downward slope section 12 and the upward slope section 11, one side (the upper side) of the plane paper 2 is attached to one side (the lower side) of the wave paper 1, the corresponding upward slope section 11 on the plane paper 2 is a front section 21, the corresponding downward slope section 12 is a rear section 22, the point where the starting point of the upward slope section 11 is in contact with the plane paper 2 is a front contact point 3, and the point where the ending point of the downward slope section 12 is in contact with the plane paper 2 is a rear contact.
In the present invention, the end points of the front section 21 and/or the rear section 22 are provided with the glue drops 5, and the end points refer to the starting point or the ending point of each section (specifically, the front section 21 and the rear section 22), and can also be understood as peak points or valley points.
In one embodiment of the present invention, the uphill section 11 and the downhill section 12 are stressed respectively to form a wrinkle structure, and the wrinkle structure is adhered and fixed to the plane paper 2 through the glue 5, wherein when pressure is applied to the uphill section 11 and the downhill section 12, the pressure is advanced along the transverse direction, and the direction of the pressure applied to each section is unchanged.
Based on the above force application method, the structure formed by the wavy paper 1 after being pressed is as follows: the fold structure formed by the upward slope section 11 is inclined and flattened towards the same direction; the pleat formation formed by the downslope Duan flattens obliquely in the same direction. Further, the direction of the inclined flattening of the corrugations formed by the uphill segment 11 is opposite to the direction of the inclined flattening of the corrugations formed by the downhill segment Duan.
The above is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
