Abstract
The utility model provides a kind of flame retardant type primary filter; including outline border; it is successively folded in the outline border equipped with the first clathrum, glass layer, filter core layer, protection bed course, the second clathrum; the filter core layer is close to the protection bed course side and sets there are three groove; it is placed with bar shaped bag in the groove, is filled with fire-resistant fluid in the bar shaped bag.The primary filter of the utility model, it may be mounted at the ventilation opening of air-conditioning device, compared with traditional primary filter, layer of glass layer is increased on the downside of filter core layer, the fusing point of glass fibre is higher, filter can effectively be slowed down to be burned out, the back side increases three bar shaped bags that fire-resistant fluid is housed on the downside of filter core layer, and bar shaped bag meets fire fusing, and fire-resistant fluid rapid osmotic is into filter core layer, fire spreading is prevented, flame retardant effect is good.
Description
Technical field
The utility model relates to filter technology fields, and in particular to a kind of flame retardant type primary filter.
Background technique
Air filter is generally made of filtering layer and frame, and air filter can be divided into just effect, middle effect according to filter effect
With efficiently etc. multiple grades.Just effect air filter is mainly used for trapping granule dust that diameter is 5 to 10 microns and various outstanding
Floating object is widely used in various air-conditioning equipments and air-conditioning system, is also used for the primary protection of multiple stage filtration system.
The fire protecting performance of most primary filter is poor currently on the market, since primary filter is installed in interior more
In air-conditioning equipment, and the material in primary filter is mostly combustible material, if fire occurs, primary filter is readily ignited,
So that inner air and outer air is circulated, accelerates fire spreading, there are biggish security risks.
Utility model content
In view of the above problems, the utility model provides a kind of flame retardant type primary filter, dust removing effects and flame retardant effect
Well.
To achieve the above object, the utility model solves by the following technical programs:
A kind of flame retardant type primary filter, including outline border are successively folded in the outline border and are equipped with the first clathrum, glass fibre
Layer, filter core layer, protection bed course, the second clathrum, the filter core layer be close to the protection bed course side set there are three groove, it is described
It is placed with bar shaped bag in groove, is filled with fire-resistant fluid in the bar shaped bag.
Specifically, four medial surfaces of the outline border are equipped with fire prevention rock wool.
Specifically, the filter core layer is honeycomb sponge.
Specifically, the protection bed course is rugosity nylon cloth with holes.
Specifically, the bar shaped bag is pp bags.The beneficial effects of the utility model are:
The primary filter of the utility model, may be mounted at the ventilation opening of air-conditioning device, with traditional primarily efficient filter
Device is compared, and layer of glass layer is increased on the downside of filter core layer, and the fusing point of glass fibre is higher, can effectively slow down filtering
Device is burned out, and the back side increases three bar shaped bags that fire-resistant fluid is housed on the downside of filter core layer, and bar shaped bag meets fire fusing, and fire-resistant fluid is fast
Speed infiltrates into filter core layer, prevents fire spreading, and flame retardant effect is good.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of flame retardant type primary filter of the utility model.
Fig. 2 is the enlarged drawing of part A in Fig. 1.
Fig. 3 is the enlarged drawing of part B in Fig. 1.
Appended drawing reference are as follows: outline border 1, fire prevention rock wool 11, the first clathrum 2, glass layer 3, filter core layer 4, groove 41, item
Shape bag 42, protection bed course 5, the second clathrum 6.
Specific embodiment
The utility model is described in further detail below with reference to embodiment and attached drawing, but the implementation of the utility model
Mode is without being limited thereto.
It is as shown in Figs. 1-3:
A kind of flame retardant type primary filter, including outline border 1 are successively folded in outline border 1 and are equipped with the first clathrum 2, glass fibre
Layer 3, filter core layer 4, protection bed course 5, the second clathrum 6, filter core layer 4 are close to protection 5 side of bed course and set there are three groove 41, groove
It is placed with bar shaped bag 42 in 41, is filled with fire-resistant fluid in bar shaped bag 42.
Preferably, four medial surfaces of outline border 1 are equipped with fire prevention rock wool 11, when a fire, flame fusing outline border 1,
The fusing point of fire prevention rock wool 11 is higher, is not easy to burn, can be improved the anti-flammability of outline border 1.
Preferably, in order to make filter core layer 4 have good air circulation and adsorbing powder dust, filter core layer 4 is honeycomb
Sponge.
Preferably, protection bed course 5 is rugosity nylon cloth with holes, and protection bed course 5 is for protecting bar shaped bag 42, simultaneously
Protection bed course 5 also can prevent fine grain dust from passing through.
Preferably, bar shaped bag 42 is pp bags, and pp bags of chance fire are i.e. molten, and fire-resistant fluid leaks out after fusing.
A kind of embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed,
But it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the common of this field
For technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
