Abstract
The utility model provides an elastic filler strip for an air filtration box. The elastic filler strip takes the shape of a rectangular strip and comprises base cloth and multiple layers of high-temperature resistance fibers, wherein the opened high-temperature resistance fibers are composited with the base cloth through a cylindrical needle machine in a needling manner, and the elastic filler strip is provided with multiple semi-circular sags so as to clamp a filter unit. According to the elastic filler strip provided by the utility model, a dustproof bag is directly clamped by using the characteristic of high elasticity of a non-woven fabric so that even though tiny friction exists in actual use, the abrasion of the dustproof bag is very slight, so that the service life of the elastic filer strip is greatly prolonged.
Description
Technical field
The utility model relates to the air cleaning facility field, and is particularly related to a kind of elastic spacer for air filtering box.
Background technology
Air filter generally is used for the air-conditioning systems such as dust proof workshop, clean room, laboratory and clean operating room.High efficiency particle air filter is mainly used in the industries such as microelectronics industry, precision instrument, national defence, space flight and aviation, instrument, health care, bioengineering, laboratory, pharmacy and food, and it is terminal to be used for the toilet, namely air conditioning terminal air-supply place.
Air filtering apparatus, filter area is large, and resistance is low, mainly is comprised of Rose Box framework, dustproof filter bag.The filter bag material mainly is by being made without spinning process by ultra-fine fibre glass, melt spray fibre web etc.For filter area is increased, filter bag reaches several meters, and the cross section ovalize, inner metal or the plastic support frame of adopting.In use, the filter bag end snaps in the panel of Rose Box framework, and the filtration fraction of filter bag is placed on the parting bead of framework, and parting bead uses metal to make usually.
Yet in use, because filter bag does not stop vibrations in the process of powered air-purifying, by the metal isolating strip long term wear, the very fast attenuation in abrading section loses filter effect, so will often change whole filter bag, has caused the significant wastage of social resources.
The utility model content
In order to reduce the wearing and tearing in the filter process, the utility model proposes a kind of elastic spacer for air filtering box, it is characterized in that, this elastic spacer is microscler strip, comprise base cloth and multilayer high-temperature fibre, wherein, the high-temperature fibre of shredding is compound by tubular needing machine and base cloth acupuncture.
Further, described elastic spacer has a plurality of semi-cylindrical canyons, with the engaging filter.
Further, described base cloth is positioned at the intermediate layer of elastic spacer, inboard and compound one or more layers high-temperature fibre in the outside of described base cloth.
Further, described base cloth is inboard identical with the number of plies of outside complex fire resistant fiber.
Further, the number of plies of described high-temperature fibre is 24 layers.
Elastic spacer described in the utility model utilizes nonwoven to have elastomeric characteristics, and directly filter is lived in engaging, even also have in actual use the friction of trace, it is also very slight to wear and tear, and has improved actual life widely.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that embodiment described herein only is used for explaining the utility model, rather than be used for restriction the utility model.
In preferred embodiment of the present utility model, air filtering box has evenly distributed a plurality of holes 4 as shown in Figure 1 on the described panel 3, and hole 4 is preferably ellipse;
Described panel back arranges many Rose Box supports 9, is used for laying filter bag, forms a large-scale filter plant that filter area is huge.
As shown in Figure 2, filter bag 8 shapes, the head ovalize is fastened on the filtration panels, the bag body usually adopt nonwoven to make, in filter bag bracing frame 6 is arranged, also be ovalize.Adopting ellipse mainly is can increase filter area in identical space.
As shown in Figure 2, the holding section 5 of described filter bag by being connected with hole 4 on the panel 3, this holding section 5 has high resiliency by forming without the spinning process manufacturing, is arranged in the Rose Box; In the different depth position of described filter bag apart from panel, a plurality of filter bag bracing frames 6 are set evenly.
As shown in Figure 4, between described evenly spaced filter bag bracing frame 6 and Rose Box support 9 elastic spacer 7 is set, oval-shaped filter bag 8 parts are fastened on the semicircular elastic spacer 7, elastic spacer 7 is fixed on the Rose Box support 9.
As shown in Figure 5, described elastic spacer 7 has a plurality of semi-cylindrical canyons of equidistant arrangement, is used for engaging filter bag bracing frame 6.
Described filter bag is made by ultra-fine fibre glass, melt spray fibre web.
Described elastic spacer is identical with described filter bag material.Because both sides' material is identical, it is also very slight to wear and tear.
The process equipment of the elastic spacer that is used for air filtering box that the utility model proposes comprises that high-temperature fibre, carding machine, cross lapping establish device, lap former, tubular needing machine and glue spraying shaping equipment, wherein:
As shown in Figure 6, all be soft nonwoven inside and outside the tubular fabric after the processing, that is, high-temperature fibre 2, the centre is base cloth 1, the high-temperature fibre number of plies of described tubular fabric in described tubular needing machine is preferably 24 layers.
Fabric after the glue spraying typing is carried out cutting, the tubular fabric after the cutting is launched, as shown in Figure 7, the fabric that launches is cut into the rectangular of one fixed width, such as Fig. 8 and shown in Figure 9, rear to cutting along the center line punching of strip fabrics.
Use in high temperature resistant occasion according to product needed, the preferred Mei Tasi of the utility model is as described high-temperature fibre.
The elastic spacer that the utility model proposes utilizes nonwoven to have elastomeric characteristics, and directly this Dust-proof bag is lived in engaging, even also have in actual use the friction of trace, it is also very slight to wear and tear, and has improved actual life widely.
