Description

Technical Field

[0001] The utility model belongs to the field of filters, and in particular relates to a filter capable of delaying flame combustion. Background Art

[0002] Air filters are generally composed of filter layers and frames. Air filters can be divided into primary, medium and high efficiency grades according to the filtering effect. Primary air filters are mainly used to capture dust particles with a diameter of 5 to 10 microns and various suspended matter. They are widely used in various air conditioning equipment and air conditioning systems, and are also used for primary protection of multi-stage filtration systems.

[0003] At present, most filters on the market have poor fireproof performance. Since the filters are installed in the indoor air-conditioning system, once a fire occurs, it will cause great damage to the filters and allow air to circulate inside and outside, accelerating the spread of the fire, posing a great safety hazard. Secondly, the filter needs to be replaced after a period of use. The filter replacement process in the existing filters is too cumbersome.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0030] The utility model will now be further described in detail with reference to the accompanying drawings.

[0031] See also Figure 1-7As shown, in this embodiment, a filter capable of delaying flame combustion is provided, comprising a filter body 1, a mounting member 2 is mounted on the top of the filter body 1, a fixing groove 3 is provided on one side of the filter body 1, a fire-blocking component is mounted in the fixing groove 3, a slide groove 5 is provided on the bottom of the filter body 1, a plurality of mounting grooves 6 are provided on the side of the slide groove 5, a limiting component is arranged in the mounting groove 6, a filter component is slidably matched in the slide groove 5, a plurality of mounting holes 18 are provided on the filter component, the mounting holes 18 cooperate with the limiting component, and a fire-blocking component is mounted on the side of the inner cavity of the filter body 1; the outer shell of the filter body 1 is made of a metal fire-blocking board;

[0032] The fireproof component includes an insulating shell 20 installed on the side of the inner cavity of the filter body 1, a spraying groove 21 is provided at the bottom of the insulating shell 20, a storage bag 22 is provided in the insulating shell 20, a liquid nitrogen fire retardant 23 is provided in the storage bag 22, a driving groove 24 is provided on one side of the insulating shell 20, and a control component is provided in the driving groove 24.

[0033] The application of one aspect of this embodiment is: when the filter body 1 is on fire, the flame temperature will cause the control component to pierce the storage bag 22, and the rupture of the storage bag 22 will cause the liquid nitrogen fire retardant 23 to flow out, so that the liquid nitrogen fire retardant 23 is ejected from the ejection slot 21, and the ejected liquid nitrogen fire retardant 23 is released into the filter body 1. When the liquid nitrogen fire retardant 23 becomes gaseous under atmospheric pressure, it will absorb a large amount of heat, thereby rapidly reducing the temperature of the surrounding environment. At the same time, water vapor and nitrogen will be generated in the process of liquid nitrogen becoming gaseous. Water vapor will absorb heat and form a mist-like mixture after mixing with nitrogen, covering the fire source area to achieve a fire extinguishing effect. When the filter body 1 is on fire outside, the fire-blocking component will seal the filter body 1, isolate the high temperature and block the fire from entering the filter body 1, thereby preventing the external fire source from causing the filter to burn. The limit component is set to facilitate the replacement of the filter component.

[0034] See also Figure 1-7 As shown, the control component of this embodiment includes a spike 25 that is slidably fitted in the driving groove 24, a first spring 26 is installed between the spike 25 and the driving groove 24, a fuse rope 27 is installed on one side of the spike 25, one end of the fuse rope 27 passes through the insulation shell 20, and a counterweight block 15 is installed on the end of the fuse rope 27 located outside the insulation shell 20; the gravity of the counterweight block 15 is greater than the elastic force of the first spring 26.

[0035] Through the control component that is set, when a fire occurs inside the filter body 1, the flame will melt the fuse rope 27, so that the counterweight block 15 no longer applies tension to the spike 25, and the first spring 26 releases the elastic force to push the spike 25 toward the storage bag 22, so that the spike 25 pierces the storage bag 22, so that the liquid nitrogen fire retardant 23 in the storage bag 22 extinguishes the fire inside the filter body 1.

[0036] See also Figure 1-4 As shown, the fire-blocking assembly of this embodiment includes a metal fire-blocking plate 4 installed in a fixing groove 3, a plurality of through holes 11 are provided on the side of the metal fire-blocking plate 4, a circular groove 12 is provided on the inner side of the plurality of through holes 11, a sealing can 13 is installed in the circular groove 12, and a water-soluble inorganic fire-proof adhesive layer 14 is provided in the sealing can 13; the material of the sealing can 13 is a high-temperature melt.

[0037] By setting up the fire-proof component, when the outside of the filter body 1 is on fire, the temperature causes the sealing can 13 to melt or rupture, and the water-soluble inorganic fire-proof adhesive layer 14 filled in the sealing can 13 foams and expands to form a hard milky white foam-like fire-proof adhesive plate to seal the through hole 11, isolating the high temperature and blocking the fire from entering the filter body 1; when the inside of the filter body 1 is on fire, the water-soluble inorganic fire-proof adhesive layer 14 foams and expands to form a hard milky white foam-like fire-proof adhesive plate to seal the through hole 11, which will block the fire from spreading to the outside of the filter body 1 and block the air circulation inside and outside the filter body 1, thereby achieving the effect of flame retardancy and delaying the fire.

[0038] See also Figure 1-5 As shown, the filter assembly of this embodiment includes a mounting frame 16 that slides in the slide groove 5, a filter element 17 is installed on the inner side of the mounting frame 16, a mounting hole 18 is opened on the side of the mounting frame 16, and the mounting frame 16 slides in the slide groove 5; the mounting frame 16 is made of fireproof material.

[0039] See also Figure 1-5 As shown, a handle 19 is installed at the bottom of the installation frame 16 of this embodiment, and a rubber sleeve is provided on the handle 19; the rubber sleeve is provided with textures for increasing friction.

[0040] See also Figure 1-5 As shown, the limiting assembly of this embodiment includes a circular slider 7 that slides in the mounting groove 6, a second spring 9 is installed between the circular slider 7 and the mounting groove 6, a clamping rod 8 is installed on the inner side of the circular slider 7, one end of the clamping rod 8 movably passes through the filter body 1, and a pull plate 10 is installed on the end of the clamping rod 8 located outside the filter body 1.

[0041] Through the set limit assembly, when the filter assembly needs to be replaced, by pulling the pull plate 10, the pull plate 10 drives the clamping rod 8 to move, thereby pulling the clamping rod 8 out of the mounting hole 18, and then by pulling the handle 19 downward, the handle 19 drives the mounting frame 16 to move, so as to facilitate the removal of the filter assembly. When the filter assembly needs to be installed, the pull plate 10 drives the clamping rod 8 to move, and then the mounting frame 16 is rubbed into the protective milk chute 5 through the handle 19. When the mounting hole 18 is flush with the clamping rod 8, the pull plate 10 is released, and under the action of the second spring 9, the clamping rod 8 is inserted into the mounting hole 18, so as to fix the filter assembly, thereby facilitating the installation and replacement of the filter assembly.
