Description

Replace air filter who moulds flat filter core and have backplate

Technical Field

The utility model relates to an air filter technical field, concretely relates to replace air filter who moulds flat filter core and have backplate.

Background

The air filter element mainly comprises filter materials which are symmetrically arranged and folded into a continuous V shape, the V-shaped tooth tips of the filter materials are bonded in a pairwise opposite mode, and two ends of the filter materials are connected with the fixing plate, the protection plate and the end cover through epoxy resin glue and the like. Generally, the guard plates at two ends of the filter material are flat, and the filter element is easy to deform due to the fact that external pressure is transmitted to the interior of the filter material through the end covers in the assembling or transporting process, so that the filter material is further deformed, and the filtering effect of the filter element is reduced.

Disclosure of Invention

An object of the utility model is to overcome the defect that exists among the prior art, provide a simple structure, protecting effect is good, the replacement that the filter media is difficult for deformation moulds the air filter who burns flat filter core and have the backplate.

In order to achieve the above object, the technical scheme of the utility model is to design a replace and mould air filter with backplate of flat formula filter core of fever, including filter media inner frame, along the filter media of the continuous V-arrangement of filter media inner frame symmetry setting with set gradually at the filter media fixed plate at filter media inner frame both ends, be used for protecting backplate, the end cover that has the angle of buckling towards the filter media direction of filter media. The middle part of backplate has certain angle of buckling, and when external pressure passed through the end cover and transmitted to the backplate, pressure pressed the position of buckling in the middle of the backplate, and two limits of backplate are contradicted with the support wall of filter media, formed a stable triangular structure, and this backplate is difficult to deform, can have better guard action to the filter media, guarantees that this filter core is difficult for deformation at the in-process of transportation, assembly.

In order to provide better protection for the guard plate, the preferred technical scheme is that the bending angle of the guard plate is 140-145 degrees.

In order to make the combination between the guard plate and the filter material tighter and prevent the guard plate from separating from the filter material, a preferred technical scheme is that both ends of the guard plate are provided with a bending section facing to the axial lead direction of the guard plate, and a transition section is arranged between the guard plate and the bending section. The changeover portion of backplate is contradicted with the both ends of filter media fixed plate, and the bending segment of backplate is buckled and is got into the pleat layer of filter media in, improves the steadiness of backplate.

According to a further preferred technical scheme, a clamping groove matched with the filter material fixing plate is formed in the inner side of the transition section. The both ends of filter media fixed plate pass through the draw-in groove with the backplate and are connected, need not to bond fixedly, and connect more firmly, avoid the backplate slippage.

According to a further preferable technical scheme, one end of the clamping groove is open, and the other end of the clamping groove is closed. The one end opening one end of draw-in groove is sealed, and the draw-in groove can be gone into to the width direction card of backplate to the tip of filter media fixed plate, contradicts to the blind end of fixed plate and draw-in groove, avoids the fixed plate when the card goes into the draw-in groove, and it is excessive to slide.

In order to further increase the stability of the triangular structure of the guard plate, improve the compression resistance of the guard plate and improve the protection effect of the guard plate, a further preferable technical scheme is that the inner side of the guard plate is provided with a reinforcing plate which is the same as the bending direction of the guard plate.

The utility model has the advantages and the beneficial effects that: this air filter with backplate has simple structure, protecting effect is good, the difficult characteristics that deform of filter media. The backplate middle part has certain angle of buckling, and when external pressure passed through the end cover and transmitted to the backplate, pressure pressed the position of buckling in the middle of the backplate, and two limits of backplate are contradicted with the support wall of filter media, formed a stable triangular structure, and this backplate is difficult to deform, can have better guard action to the filter media, guarantees that this filter core is difficult for deformation at the in-process of transportation, assembly. The both ends of backplate have the bending segment, have the changeover portion between backplate and the bending segment, and the changeover portion of backplate is contradicted with the both ends of filter media fixed plate, and the bending segment of backplate is buckled and is got into in the pleat layer of filter media, makes the combination between backplate and the filter media inseparabler, prevents that backplate and filter media break away from, improves the steadiness of backplate. The both ends of filter media fixed plate pass through the draw-in groove with the backplate and are connected, need not to bond fixedly, and connect more firmly, avoid the backplate slippage. The one end opening one end of draw-in groove is sealed, and the draw-in groove can be gone into to the width direction card of backplate to the tip of filter media fixed plate, contradicts to the blind end of fixed plate and draw-in groove, avoids the fixed plate when the card goes into the draw-in groove, and it is excessive to slide. The backplate inboard sets up the reinforcing plate, further increases the stability of the triangular structure of backplate, improves the compressive property of backplate, improves the protection effect of backplate.
