Description

Technical Field

[0001] This utility model relates to the field of high-temperature resistant filter material technology, specifically a fireproof multilayer high-temperature resistant filter material. Background Technology

[0002] High-temperature resistant filter media refers to filter media materials that have good filtration performance and tolerance in high-temperature environments. They can withstand high temperatures, are corrosion-resistant, not easily deformed, and have a long service life. Therefore, they are widely used in many high-temperature industries.

[0003] Existing fire-resistant multi-layer high-temperature resistant filter media devices are typically used in air purification and filtration systems in high-temperature industries such as steel, chemical, power, and cement. For high-temperature filtration operations in circular pipes, the filter media is designed to be circular, and multiple materials are used to enhance its high-temperature filtration effect. This requires structural design features to evenly distribute the high temperature to other areas of the device, maximizing the filter media's filtration area. However, when filtering hot air or combustion flames, there are no effective measures for particulate matter, which can eventually clog the filter pores and reduce the device's lifespan. Therefore, a fire-resistant multi-layer high-temperature resistant filter media is needed to solve these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a fire-resistant, multi-layered, high-temperature resistant filter material that has the advantages of intercepting particulate matter and dispersing high temperatures, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a fireproof multilayer high-temperature resistant filter material, comprising a metal frame, a high-temperature resistant glass layer sleeved on the inner wall of the metal frame, a high-temperature resistant adhesive on the outer wall of the high-temperature resistant glass layer, a ceramic sheet on the outer wall of the high-temperature resistant adhesive, an inner groove on the inner wall of the metal frame, protrusions connected to the outer wall of the inner groove, an internal thread on the inner wall of the metal frame, a filter bag in the inner cavity of the metal frame, a round hole on the outer wall of the filter bag, and an installation assembly sleeved on the inner wall of the metal frame.

[0006] As a preferred embodiment of this utility model, the metal frame is made of metal material, and the inner cavity of the metal frame is provided with a connecting rod.

[0007] As a preferred embodiment of this utility model, the high-temperature resistant glass layer is made of inorganic non-metallic materials, and the number of high-temperature resistant glass layers is five.

[0008] As a preferred embodiment of this invention, the high-temperature resistant adhesive is applied to the surface of the high-temperature resistant glass layer, and the ceramic sheet is bonded to the outer wall of the high-temperature resistant glass layer by the high-temperature resistant adhesive.

[0009] As a preferred embodiment of this utility model, the number of protrusions is six, and the outer wall of the protrusions is adapted to the size of the inner wall of the circular hole.

[0010] As a preferred embodiment of this invention, the filter bag is made of polyimide and is configured as a pocket.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This fireproof multi-layer high-temperature resistant filter material, through the coordinated use of the metal frame, high-temperature resistant glass layer, and filter bag on the device, allows the metal frame to be set into multiple filtration zones using the properties of the metal material. The high-temperature resistant glass layer is embedded in the filtration zone to filter hot air or combustion flames. The material characteristics of the high-temperature resistant glass layer provide heat resistance and corrosion resistance to hot air or combustion flames. Furthermore, there is a filter bag behind the high-temperature resistant glass layer, which filters the remaining heat. In turn, the pocket-shaped filter bag intercepts combustion particles carried in the hot air.

[0013] 2. This fireproof, multi-layered high-temperature resistant filter material utilizes the combined use of ceramic sheets, high-temperature resistant adhesive, and a high-temperature resistant glass layer. The ceramic sheets are made of ceramic, and when they are bonded to the surface of the high-temperature resistant glass layer with the high-temperature resistant adhesive, the high hardness, high strength, high wear resistance, and high-temperature resistance of the ceramic sheets allow the high temperature concentrated at the center of the pipe to preferentially contact the surface of the ceramic sheets as hot air or combustion flames flow through the pipe. The heat then disperses from the surface of the ceramic sheets to the surrounding areas, effectively dispersing the heat and fully utilizing the high-temperature resistant glass layer for filtration.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 A fireproof, multi-layered, high-temperature resistant filter material includes a metal frame 1, a high-temperature resistant glass layer 2 fitted onto the inner wall of the metal frame 1, a high-temperature resistant adhesive 3 on the outer wall of the high-temperature resistant glass layer 2, a ceramic sheet 4 on the outer wall of the high-temperature resistant adhesive 3, an inner groove 5 on the inner wall of the metal frame 1, protrusions 6 connected to the outer wall of the inner groove 5, an internal thread 7 on the inner wall of the metal frame 1, a filter bag 8 in the inner cavity of the metal frame 1, a round hole 9 on the outer wall of the filter bag 8, and an installation component 10 fitted onto the inner wall of the metal frame 1. Through the cooperation of the metal frame 1 and the installation component 10, when the entire device needs to be installed, the inner wall of the metal frame 1 and the outer wall of the installation component 10 are threaded together, so that the metal frame 1 can be installed in the pipeline through the installation component 10.

[0021] In a preferred embodiment, the metal frame 1 is made of metal, and the inner cavity of the metal frame 1 is provided with a connecting rod. Due to the fact that the metal frame 1 of the device is made of metal, the metal frame 1 of the device has high temperature resistance, corrosion resistance and chemical stability. Moreover, the metal material can work for a long time in an environment with temperatures up to 500°C, so that the metal frame 1 of the device is made of metal.

[0022] In a preferred embodiment, the high-temperature resistant glass layer 2 is made of inorganic non-metallic material, and there are five high-temperature resistant glass layers 2. Due to the characteristic that the high-temperature resistant glass layer 2 on the device is an inorganic non-metallic material, the high-temperature resistant glass layer 2 on the device has the characteristics of strong heat resistance and good corrosion resistance. The high-temperature resistant glass layer 2 is filled in the inner cavity of the metal frame 1, so that the metal frame 1 on the device works with the high-temperature resistant glass layer 2 to perform filtration and heat resistance.

[0023] In a preferred embodiment, high-temperature resistant adhesive 3 is applied to the surface of the high-temperature resistant glass layer 2, and ceramic sheets 4 are bonded to the outer wall of the high-temperature resistant glass layer 2 by the high-temperature resistant adhesive 3. By applying high-temperature resistant adhesive 3 to the surface of the high-temperature resistant glass layer 2, a large number of ceramic sheets 4 are bonded to the surface of the high-temperature resistant glass layer 2 by the high-temperature resistant adhesive 3. The ceramic sheets 4 are concentrated in the center of the metal frame 1 and the high-temperature resistant glass layer 2 and gradually diffuse outward, so that when the device is used in a pipeline environment, the ceramic sheets 4 resist the heat accumulation area in the center of the pipeline and perform fireproof and heat insulation work.

[0024] In a preferred embodiment, there are six protrusions 6, and the outer wall of the protrusion 6 is adapted to the size of the inner wall of the circular hole 9. Through the six protrusions 6 on the device, when the filter bag 8 on the device needs to be installed with the metal frame 1, the multiple protrusions 6 are used to engage with the position of the circular hole 9, so that the filter bag 8 on the device can be installed in the inner cavity of the metal frame 1.

[0025] In a preferred embodiment, the filter bag 8 is made of polyimide and is configured as a pocket. The filter bag 8 is made of polyimide, which makes it resistant to high temperatures. The pocket shape allows hot air or combustion flame in the pipeline to enter the inner cavity of the metal frame 1. The filter bag 8 then intercepts and discharges the particulate matter carried by the hot air or combustion flame and stores it in the inner cavity of the filter bag 8.

[0026] The working principle involves the coordinated use of a metal frame 1, a high-temperature resistant glass layer 2, and filter bags 8. The metal frame 1 is configured into multiple filtration zones, with the high-temperature resistant glass layer 2 embedded within each zone. This glass layer 2 filters hot air or combustion flames, and its material properties provide heat resistance and corrosion resistance. Following the high-temperature resistant glass layer 2 are the filter bags 8, which filter the remaining heat. The pocket-like shape of the filter bags 8 traps combustion particles carried in the hot air. The object is intercepted, and then through the combined use of the ceramic sheet 4, high-temperature adhesive 3, and high-temperature glass layer 2 on the device, the ceramic sheet 4 on the device is made of ceramic. When the ceramic sheet 4 on the device is attached to the surface of the high-temperature glass layer 2 using the high-temperature adhesive 3, the high hardness, high strength, high wear resistance, and high temperature resistance of the ceramic sheet 4 are utilized. This allows the high temperature accumulated at the center point of the hot air or combustion fire in the pipe to preferentially contact the surface of the ceramic sheet 4, and then disperse from the surface of the ceramic sheet 4 to the surrounding areas, so that the heat is dispersed around and fully utilized for filtration by the high-temperature glass layer 2.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
