Abstract
The utility model discloses a primary air filtering device comprising an outer framework and a primary filtering device. The primary air filtering device is characterized in that the primary filtering device is arranged inside the outer framework and the outer framework consists of a firm waterproof plate and is used for fixing a folded filtering material; due to the design of a diagonal line of the outer framework, an overlarge filtering area can be provided and the inner filtering material is tightly stuck on the outer framework; the periphery of the primary filtering device is stuck with the outer framework through a bonding agent; and the filtering material is a non-woven fabric and is arranged into a high-strength film and a hard paperboard in a folding manner. The primary air filtering device is mainly used for filtering dust grains with the grain diameter being more than 5microns and has the advantages of low cost, light weight, good commonality and compact structure.
Description
Technical field
The utility model relates to a kind of just effect air filter.
Background technology
The air of unprocessed mistake contains a lot of impurity, if do not remove these impurity, they will cause extra production loss, thereby reduces the quality of production and improve maintenance cost, in industrial production, improves air quality and reduces production costs exactly.
Summary of the invention
For solving above-mentioned existing shortcoming, main purpose of the present utility model is to provide a kind of first effect air filter of practicality, can effectively filter the above dust particle of 5 μ m, and is cheap, lightweight, versatility is good, compact conformation.
For reaching above-described purpose, just effect air filter of the present utility model is taked following technical scheme:
A kind of just effect air filter, it comprises outside framework and primarily efficient filter device, it is characterized in that, the primarily efficient filter device is arranged in the outside framework.
A kind of just effect air filter, it is characterized in that, described outside framework is to form with firm splash guard, is used for fixing the folding filtering material of finishing, cornerwise design can provide large filter area on the outside framework, and the self-filtering material is sticked on the outside framework closely.
A kind of just effect air filter is characterized in that, and is all bonding with adhesive and outside framework around the described primarily efficient filter device.
A kind of just effect air filter is characterized in that the filtering material of described primarily efficient filter device is nonwoven, be with folded form pack that high strength is touched into and hardboard in.
Adopt as above the utility model of technical scheme, have following beneficial effect:
Can effectively filter the above dust particle of 5 μ m, cheap, lightweight, versatility is good, compact conformation.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein: 1 outside framework; 2 primarily efficient filter devices; 3 filtering materials.
The specific embodiment
In order to further specify the utility model, further describe below in conjunction with accompanying drawing:
As shown in the figure, a kind of just effect air filter of the present utility model, it comprises outside framework 1 and primarily efficient filter device 2, it is characterized in that, primarily efficient filter device 2 is arranged in the outside framework 1.Outside framework 1 is to form with firm splash guard, is used for fixing the folding filtering material 3 of finishing, and cornerwise design can provide large filter area on the outside framework 1, and self-filtering material 3 is sticked on the outside framework 1 closely.All bonding with adhesive and outside framework 1 around the primarily efficient filter device 2, can prevent air leakage or cause damaged situation generation because of windage pressure.The filtering material 3 of primarily efficient filter device 2 is nonwoven, be with folded form pack that high strength is touched into and hardboard in, front face area is increased, will flow into airborne dust particle and be filtered material 3 and effectively be blocked between pleat and the pleat, pure air evenly flows out from another side.
A kind of just effect air filter of the present utility model can effectively filter the above dust particle of 5 μ m, and is cheap, lightweight, versatility is good, compact conformation.
