In order to make the purpose, technical solution and advantages of the present invention clearer, the following will combine the embodiments of the present invention and the corresponding drawings to perform clear and complete description of the technical solution of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

The utility model discloses an embodiment provides a filter plate of flute type, as shown in fig. 1 and fig. 2, this filter plate is including piling up the ripples layer 1 and the plane layer 2 that set up in turn, wherein, the ripple structure has on the ripples layer 1, form a plurality of pipelines 3 of buckling with the cooperation of plane layer 2, along filtering direction, should buckle pipeline 3 and extend to the other end of filter plate by the one end of filter plate, and it has the filter material to fill between ripples layer 1 and the plane layer 2, be promptly inside pipeline 3 buckles, and it has the filter material to fill between two adjacent pipelines 3 of buckling. It should be noted that, when the filter plate filters air, air is blown in from the end of the filter plate where the opening of the bent pipe is formed, so that the air can pass through the bent pipe 3 and between two adjacent bent pipes 3, and can fully contact with the filter material therein, thereby realizing air filtration.

In the filter plate of the utility model, the corrugated layer with the corrugated structure and the plane layer are alternately stacked to form a bending pipeline, so that the filter material can be completely filled between the corrugated layer and the plane layer, the generation of filling gaps is effectively prevented, and the filtering efficiency of the filter plate to air is improved; and because of the supporting function of the bent pipeline, the structure of the filter plate is firmer and has higher mechanical strength.

In this embodiment, as shown in fig. 1 and fig. 2, the plurality of bent pipes 3 in the same layer are arranged in parallel, so that air can uniformly pass through the filter plate, and the filtering efficiency of the air can be effectively improved. The bent pipelines are arranged at intervals, the interval distance is 5-40 mm, and the interval distance between every two adjacent bent pipelines can be the same or different.

Further, the shape of buckling of the pipeline of buckling in this embodiment specifically is the S type, and this S type pipeline of buckling is periodic arrangement, and the time that can make the air pass through in tortuous pipeline like this is longer, and then strengthens air purification effect to can also change the stress state of filter material in the pipeline of buckling, make the filter material concentrate to the trough direction of the S type pipeline of buckling, and then can reduce the extrusion force of filter material to the pipeline mouth of buckling production, prevent that the filter material from falling out from the pipeline mouth of buckling. Wherein, the vertical distance between the wave crest and the wave trough of the S-shaped bent pipeline is 4 mm-40 mm, and the wavelength is 5 mm-50 mm. Of course, in other embodiments, the bending shape of the bending pipe may be V-shaped or W-shaped, or other shapes.

In addition, the cross section of the bent pipeline in the direction perpendicular to the length direction is in the shape of an arc, and the arc has a better supporting effect, so that the structure of the filter plate is firmer. Wherein the height of the circular arc is 3 mm-20 mm.

In this embodiment, the corrugated layer and the flat layer are fixedly connected by adhesion, so that the filter plate structure is light and firm. Of course, the corrugated layer and the planar layer may be fixedly connected by other means.

The material of the wave form layer and the plane layer in this embodiment is preferably activated carbon paper, and like this, wave form layer and plane layer also can adsorb the particulate matter in the air to when the filter plate is abandoned, can carry out recycle to wave form layer and plane layer, and then reduce the pollution that produces the environment. Of course, the corrugated layer and the flat layer may be made of other materials such as non-woven fabric, polymer film or corrugated paper. In other embodiments, the material of only the corrugated layer or the planar layer may be activated carbon paper, non-woven fabric, polymer film or corrugated paper.

In this embodiment, the filter material is granular, and the grain size is 2mm ~ 4mm, so it is convenient for the filter material to pack into between wave-shaped layer and the surface course.

In this embodiment, a planar net, a hot melt adhesive line or a thread line is fixed at an end of the filter plate, the planar net, the hot melt adhesive line or the thread line is fixed at an end of the filter plate, which is provided with an opening of the bending pipeline, in a bonding manner, and the diameter of the planar net, the hot melt adhesive line or the thread line is 0.1mm to 1mm. In this way, the filter material is prevented from falling out between the corrugated layer and the planar layer.

And, adjacent two-layer bent pipe overlaps the setting, and when tailorring the filter plate, the structural position of each wave layer corresponds like this, makes the overall structure after tailorring more regular, can not lead to the appearance in space.

The manufacturing process of the filter plate in the embodiment specifically comprises the following steps:

first, a corrugated structure is pressed on a corrugated layer using an S-pit single corrugator, and then the corrugated layer and the flat layer are fixedly joined by an adhesive to form a single tile.

Next, a plurality of single tiles are stacked, and the positions of the peaks and valleys in the upper and lower layers are aligned when stacking, and then fixed using an adhesive to form a stacked block.

And thirdly, cutting the stacked block, selecting a wave crest or a wave trough at the cutting position, and enabling the end part of the cut stacked block to be completely positioned at the wave crest or the wave trough, so that the extrusion force of the filter material on the plane net can be reduced.

And then, a plane net is adhered to one cutting surface of the stacking block, and the aperture of the plane net can ensure that the granular filter material to be filled can not fall off from the opening part of the bent pipeline and can not generate excessive resistance.

And finally, screening granular filter materials with proper particle sizes, filling the filter materials from the non-adhered ends of the stacked blocks until the bent pipelines and the space between the bent pipelines are almost filled, blowing off the granular filter materials staying at the non-adhered ends, and adhering the plane net to the non-adhered ends of the bent pipelines to form the filter plate.
