Description

Honeycomb filter

technical field

The utility model relates to the technical field of filter nets, in particular to a corrugated honeycomb filter net which can easily adjust the three-dimensional shape of the filter net.

Background technique

The filter screen in the form of honeycomb structure has the advantages of light weight and high strength, and is widely used in filter systems in construction, aviation and other fields. The filter net with a honeycomb structure can be formed by extrusion or corrugated molding. Choose the material of the filter according to different manufacturing methods and target functions. Among them, the process of manufacturing filter screens by corrugated molding is relatively mature and has a wide range of applications.

Figure 1 shows a planar structure of an existing corrugated honeycomb filter net, wherein a layer of flat layers 10 and a layer of core layer 11 adjacent to each other are combined to form a layer of corrugated in a corrugated shape layer. The flat layer 10 is generally formed of flat paper, and the core layer 11 is generally formed of corrugated core paper. A multi-layer corrugated laminate is formed by stacking multiple corrugated layers, and a sheet-shaped filter net is obtained by cutting the laminate.

In the plan view shown in Figure 1, the central core layer 11 has a plurality of corrugated peaks and valleys (hereinafter collectively referred to as corrugated vertices), and forms a contact between the flat plate layer 10 and the central core layer 11 at these corrugated vertices. Contact position A. Adhesive is coated on the vertices of the corrugations, so that the flat layer 10 and the core layer 11 are bonded to each other at the contact position A. Fig. 2 shows a situation where a flat plate layer 10 and a core layer 11 are laminated and adhered to each other to form a corrugated laminated body. Multiple layers of laminates as shown in Figure 2 can be stacked and bonded repeatedly (this process is also called lamination) until the desired stack height is reached.

Fig. 3 shows the three-dimensional shape of the laminated body after the lamination is completed. As shown in FIG. 3 , by cutting the laminated body, a sheet-shaped corrugated honeycomb filter can be obtained.

However, in actual use, depending on the structure of the equipment using the filter, it is often necessary to make the filter into various three-dimensional shapes such as a cylinder, a triangular cylinder, or a square cylinder. The existing corrugated honeycomb filter is not easy to bend or stretch due to the limitation of the poor ductility of sheet materials such as paper and the difficulty of elastic deformation of the bonding structure, so when the sheet filter is bent into There are defects that are difficult to process in various three-dimensional shapes. If it is bent forcibly, the adhesive part or the sheet material will crack and the shape of the filter will not be maintained.

Utility model content

Problems to be solved by the utility model

The honeycomb filter net of the utility model can overcome the defect that the corrugated honeycomb filter net is not easy to bend or stretch in the prior art, so that it can be conveniently formed into a three-dimensional shape.

solutions to problems

The utility model provides a honeycomb filter net, which includes alternately stacked flat plate layers and a corrugated core layer, which is characterized in that the core layer includes at least one segmentally connected core layer, the The segmentally connected core layer is a core layer in which at least a part of the corrugated vertices and the adjacent flat plate layers are connected or integrated with each other at least among the corrugated vertices on the same side of the core layer in the lamination direction to form a connected segment , and another part of corrugated vertices is independent from the adjacent flat layer to form a separate segment.

The core layer and the adjacent flat layers are connected to each other in segmental connection at the connection section, and the core layer and the adjacent flat layers can be separated from each other in the segmental connection at the separation section. Through this segmented corrugated structure, the honeycomb filter can be easily stretched in the lamination direction of the corrugated laminate. In this way, the sheet-shaped filter net can be easily bent into various three-dimensional shapes.

Preferably, when the corrugated vertices in the connecting segment of the segmentally connected core layer are connected to the adjacent flat layer, the corrugated vertices in the connecting segment are connected to the adjacent There is an adhesive structure between the flat layers.

Since the existing equipment can be used to apply adhesive to the position where the core layer and the flat layer are connected to each other, the technical scheme of connecting the corrugated apex in the connecting section with the adjacent flat layer through the bonding structure is beneficial in Realize the design of the utility model on the basis of existing equipment. In addition, since no adhesive is applied in the separation section, the connection part is reduced. Compared with the original processing method, the amount of adhesive used is reduced and the cost is saved; at the same time, the contact area with the air is increased, improving It improves the filtering effect and helps to improve the deodorizing effect.

Preferably, the core layers are all the segmented core layers.

When bending a sheet-shaped honeycomb filter into a three-dimensional shape such as a cylinder, it is necessary to use the corrugated layer located on the outermost side in the stacking direction as the seam position of the three-dimensional shape. Corrugated layers with segmentally bonded cores may be used as seam locations. However, it is also possible to make all the corrugated vertices of the core layer in the outermost layer or layers of corrugated layers in the lamination direction all be connected with the adjacent flat layers or form an integral body, when the curvature of the sheet-like honeycomb filter When large, this helps to improve the joint strength at the seam location, and also facilitates clamping or holding of the filter during bending operations.

Preferably, in the segment-connected core layers adjacent to each other in the lamination direction, the connection segments in each layer of the segment-connected core layer are connected to adjacent segments in the lamination direction The separate segments in the core layer are adjacent.

Since the connecting section is adjacent to the separation section in the stacking direction, it can ensure that the honeycomb filter net is easily stretched in the stacking direction of the corrugated layers, thereby facilitating bending of the filter net.

Preferably, the distance between two adjacent corrugation vertices on the same side of the core layer in the stacking direction is in the range of 0.5mm-20mm. If the distance between two adjacent corrugation vertices is too narrow, the airflow will be hindered from passing through the filter screen, and if the distance is too wide, the contact area between the gas and the filter screen will be reduced, which will have an adverse effect on the filtration performance.

The effect of utility model

Utilizing the utility model, even if the corrugated honeycomb filter net is made of a sheet material that is not easy to bend, the finished sheet filter net can be easily bent into a cylindrical shape, a triangular cylindrical shape, or a square cylindrical shape, etc. various three-dimensional shapes.

detailed description

Specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. For the convenience of description, a corrugated honeycomb filter made of sheet materials including paper is used as a specific embodiment of the present invention. However, the material of the present invention is not limited thereto, and may also be other materials suitable for use as a filter such as non-woven fabric.

In the following description, the same components are given the same reference numerals, and repeated descriptions will be omitted.

first embodiment

FIG. 4 is a schematic diagram showing the configuration form between one segmentally connected core layer 110 and two adjacent flat plate layers 10 . This embodiment employs the same flat sheet layer 10 as the filter shown in FIG. 1 . In an unstretched state, the honeycomb filter of this embodiment has the same planar form as that shown in FIG. 1 . The difference between this embodiment and the prior art is that when the honeycomb filter mesh of this embodiment is stretched along the stacking direction, the state shown in FIG. 5 is formed. The honeycomb filter can be stretched by rolling.

In FIG. 4 , in order to distinguish it from the prior art, only one segmentally connected core layer 110 and two adjacent flat plate layers 10 are shown. In FIG. 1 , an adhesive is coated on all corrugated apexes of the core layer 10 , so that each corrugated apex is connected to the flat plate layer 10 . In Fig. 4, along the left-right direction shown in the figure (i.e. the extending direction of the corrugations), a connecting segment and a separating segment are arranged in the segmented connecting core layer 110, wherein the connecting segment includes two corrugated vertices, and the separating segment Include more than two ripple vertices in . It is easy to understand that the corrugated vertices included in the connecting section and the separating section are not limited thereto, and may be one or any number, as long as the purpose of the present utility model can be achieved. Note that the connection section defined here refers to a portion in which the corrugated apexes included in the connection section are all connected to the flat plate layer 10 via the adhesive 20 . The separation section defined here refers to a portion in which the corrugation vertices included in the separation section are all independent from the flat plate layer 10 .

As shown in FIG. 4 , an adhesive 20 is used to bond between the corrugated vertices in the connecting section and the adjacent flat plate layers 10 , so as to form a bonded structure. The corrugated vertices in the separation section are in contact with the adjacent flat sheet layer 10 in the unstretched state shown in FIG. 4 , and are separated from the adjacent flat sheet layer 10 in the stretched state shown in FIG. 5 . Therefore, when the honeycomb filter net of this embodiment is bent into a three-dimensional shape as shown in FIGS. shape.

The adhesive 20 shown in FIG. 4 is applied only at the vertices of the corrugations. However, this is not restrictive and other forms are possible. For example, the adhesive 20 may be continuously applied in the range where two or more corrugation vertices adjacent to each other are located. No matter what kind of adhesive coating method is used, since no adhesive is applied in the separation section, the connection part is reduced. Compared with the original processing method, the amount of adhesive used is reduced and the cost is saved; at the same time , The contact area with the air is increased, which improves the filtering effect and helps to improve the deodorizing effect.

In FIG. 4 , H represents the corrugation height in the segmentally connected core layer 110 , and W represents the distance between two adjacent corrugation vertices on the same side in the stacking direction (the up-down direction in FIG. 4 ). If the corrugation height H of the corrugated vertices is too high or the distance W between two adjacent corrugated vertices is too wide, the gaps in the honeycomb filter will be too large, which will easily have an adverse effect on the filtering performance. If the corrugation height H is too low or the distance W is too narrow, the gap of the honeycomb filter will be too small, so that the airflow cannot pass through smoothly, and it is easy to have an adverse effect on the filtration performance.

In this embodiment, the value of the corrugation height H may be in the range of 1.8mm-3.5mm, and the value of the distance W may be in the range of 4.9mm-6.2mm. It should be noted that the numerical ranges of the corrugation height H and the distance W given here are only for better illustrating the present embodiment, and are not intended to limit the present utility model. The configuration of the present embodiment can be applied to other corrugation heights H and distances W other than the above ranges.

As shown in Figure 5, three layers of corrugated layers with the same structure as in Figure 1 are arranged on the outermost side (upper side and lower side in Figure 5) of the stacking direction of the honeycomb filter net, and the central core layer is the same as that shown in Figure 1. 1 shows the core layer 11. During bending, these corrugated layers will not be stretched, so that it is convenient to clamp with tools or hold by hand, and the use of these corrugated layers is beneficial to improve the strength of the joint position. The outermost core layers 11 in the lamination direction are not limited to the three layers shown in FIG. 5 , and may be more layers, or one or two layers, and the corrugated layer shown in FIG. 1 may not be provided.

In the structure shown in FIG. 5 , in the stacking direction of the corrugated layers (the up-and-down direction in FIG. 5 ), the corrugated layers are arranged in a structure in which the layers are connected. More specifically, in the multi-layered corrugated layers stacked on each other as shown in FIG. 5 , the joining segments in each layer of segment-joined core layer are separated from those in the adjacent segment-joined core layer in the stacking direction. The segments are adjacent. Therefore, in the structure shown in FIG. 5 , the connection segments are arranged alternately with the separation segments in the stacking direction of the corrugated layers, thereby forming the aforementioned interlayer connection structure. It is easy to understand that the use of this interlayer connection structure can ensure that the honeycomb filter mesh is easily stretched in the lamination direction of the corrugated layers, thereby facilitating bending of the filter mesh.

The manufacturing process of the honeycomb filter of this embodiment is demonstrated below.

First, in a manner similar to Figure 2, a layer of core material is stacked on a layer of flat material to form a layer of corrugated layers. Wherein, the adhesive 20 is only applied at the vertices of the corrugations corresponding to the connection segments in the segment connection core layer 110 . In addition, in the segmentally connected core layers 110 adjacent in the stacking direction, the application position of the adhesive 20 corresponds to the connection position in the structure of interlayer connection shown in FIG. 5 . The flat plate material and the core material are alternately laminated repeatedly to form a laminated body having a plurality of corrugated layers.

In a manner similar to that shown in Figure 3, the laminated body was cut to obtain a sheet-shaped honeycomb filter.

Then, as required, the sheet-shaped honeycomb filter is bent into various three-dimensional shapes such as shown in FIGS. 6 to 8 .

other implementations

In the first embodiment described above, the core layer and the flat plate layer are connected to each other by adhesive means. However, instead of lamination and bonding means, the corrugated vertices of the core layer and the flat plate layer can also be combined with each other by other means such as integral molding, thereby realizing the structure in the above-mentioned embodiment.

While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. Various changes and modifications can be made by those skilled in the art without departing from the scope of the claims.
