Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the present invention, it is to be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. When a component is referred to as being "disposed on" another component, it can be directly on the other component or intervening components may also be present.
Furthermore, the terms "long", "short", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention, but do not indicate or imply that the referred devices or elements must have the specific orientations, be configured to operate in the specific orientations, and thus are not to be construed as limitations of the present invention.
The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.
As shown in fig. 1 to 4, the present embodiment provides a filter including a case 1, a screen assembly 2, and a protective mesh 3. The middle part of the shell 1 is provided with a through groove, and the filter screen assembly 2 is fixed in the through groove. The number of the filter screen assemblies 2 is one. Of course, the number of the filter screen assemblies 2 may also be two, three, four or even more, and when the number of the filter screen assemblies 2 is at least two, the filter screen assemblies 2 are arranged at intervals along the groove depth direction of the through groove. Preferably, the distance between two adjacent screen assemblies 2 is equal. The protective net grids 3 are fixed on the notches of the through grooves, and the protective net grids 3 are metal nets or metal plates with meshes. The filter and screen assembly provided by the invention has the advantages of small wind resistance, large loading of the particle adsorption medium in unit volume and more sufficient contact between the medium and the gas passing through the medium.
In the present embodiment, the screen assembly 2 includes a support portion 201 and an adsorption medium 202. The supporting portion 201 is a mesh structure having a plurality of through holes, and preferably, the supporting portion 201 is bent into a zigzag shape of a "W", but of course, the supporting portion 201 may also be made into an arc structure that is arched toward the air inlet side. The adsorption medium 202 is fixed on the surface of the support portion 201 by a substance such as an adhesive, and is used for adsorbing impurities, odor or harmful gas in the fluid passing through the screen assembly 2. Specifically, the filter screen subassembly 2 that this embodiment provided need not to use the technical scheme of the thin little active carbon of two-layer non-woven fabrics parcel, and the adsorption medium 202 that the adhesion granularity is great directly on supporting part 201 can increase the space clearance between the active carbon, great reduction windage. Further, the adsorbent media 202 may be a cylinder, and may also be a rectangular parallelepiped, a cylinder, or even an irregular other shape.
In this embodiment, the adhesive is located between the adsorption medium 202 and the supporting portion 201, and the adsorption medium 202 is attached to the surface of the supporting portion 201 through the adhesive. Further, an adsorption medium 202 may be adhered to one side or both sides of the support 201. Specifically, the adsorption media 202 are adhered to both sides, which can effectively improve the adsorption capacity of the unit volume of the screen assembly 2.
In this embodiment, the adsorption medium 202 is activated carbon or other adsorbents such as broad-leaved mud that can adsorb odor and impurities. Preferably, the particle size of the activated carbon is above 0.1mm and below 5 mm. Specifically, the particle size of the traditional activated carbon is less than 0.1mm, and the filter screen assembly 2 provided by the embodiment can reduce the particle size requirement on the activated carbon and reduce the production cost.
In this embodiment, the supporting portion 201 may be made of metal, plastic, wood structure or other composite materials, as long as it has a certain stiffness and can support the adsorbing medium 202 for molding.
In particular, the present embodiment provides the filter with advantages of: the adsorption capacity of the filtering component in unit volume is larger; wind resistance is lower; the adsorption medium 202 is more fully contacted with the passing gas; and fourthly, the optimal harmful gas removing effect is achieved.
