Description

Technical Field

[0001] The utility model relates to the technical field of filter screens, in particular to a modified graphene air filter screen. Background Technique

[0002] Air filter screens are divided into four types: coarse efficiency, medium efficiency, sub-high efficiency, and high efficiency. Different numbers of air filters are installed in a duct according to the amount of air volume. The filter section is installed in a central air-conditioning system to filter out the dust particles in the air sent into the room, so as to achieve high-quality indoor air.

[0003] When the existing air filter screen is in use, the surface of the air filter screen is prone to dust accumulation after long-term use. However, the filter screen installed in a fixed manner is difficult to disassemble and assemble, and the filter screen installed in a plug-in manner has a problem of poor sealing performance, resulting in poor filtering effect. At the same time, the dust accumulation on the surface of the filter screen also causes the problem of reduced service life of the filter screen.

[0004] Based on this, a modified graphene air filter screen with high sealing performance is designed, and at the same time, it also has the characteristic that the surface of the filter screen is not prone to dust accumulation. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the utility model provides the following technical solution: a modified graphene air filter screen, which includes a duct. A flange connection disk for connection is welded at the air outlet end of the duct. A detachable filter element is installed on the inner surface of the flange connection disk, and the filtering mechanism is located inside the duct. The detachable filter element arranged inside the duct enables the filter element to filter air and is also convenient for disassembling and maintaining the filter element. An inner ring of the flange connection disk is welded with a support plate. Two ends of the support plate are welded with a first protection net for protection. A shaft rod is welded on the inner surface of the support plate, and a plurality of fans are installed on the shaft rod. A wind speed monitoring module for monitoring the wind speed is also installed inside the support plate. The support plate, the shaft rod and the fans installed inside the duct facilitate the unidirectional flow of the air inside the duct under the action of the fans, so as to facilitate the flowing air to pass through the filter element for filtering.

A sealing rubber ring is also adhered to the inner side of the flange connection disc, and the sealing rubber ring contacts the outer surface of the end of the modified graphite filter screen. A diversion groove for air diversion is arranged on the outer surface of the modified graphite filter screen, and the diversion groove is of a spiral structure. A ball head is integrally formed at the end of the modified graphite filter screen; the filter element is composed of a modified graphite filter screen, a non-woven filter screen inner layer, a limiting groove, a magnet ring, an iron ring, a sealing rubber ring, a diversion groove and a ball head. The modified graphite filter screen is installed outside the non-woven filter screen inner layer, and the modified graphite filter screen and the non-woven filter screen inner layer cooperate to filter air. The magnet ring adhered in the limiting groove formed at the end of the modified graphite filter screen is fixed by the iron ring adhered to the surface of the flange connection disc, so that the filter element is fixedly connected to the flange connection disc by magnetic attraction. The diversion groove arranged on the outer surface of the modified graphite filter screen enables the air outside the filter element to be diverted through the diversion groove, and further enables the air outside the filter element to flow spirally, so that the spiral air flow blows off the dust on the outer surface of the modified graphite filter screen, reducing the stacking of dust on the outer surface of the modified graphite filter screen. The ball head integrally formed at the end of the modified graphite filter screen facilitates the disassembly of the filter element by grasping outside the ball head.

[0007] As an improvement of the above technical solution, one end of the filter element is of a conical structure, and the other end of the filter element is of a circular tubular structure.

[0008] As an improvement of the above technical solution, the diversion grooves are distributed in an array.

[0009] As an improvement of the above technical solution, a detachable protective member is arranged at one end of the air duct away from the flange connection disc.

[0010] As an improvement of the above technical solution, the protective member includes a support ring fixed to the inner surface of the opening of the air duct, and a magnet block adhered and fixed to the side surface of the support ring. A second protective net magnetically fixed to the magnet block is further arranged on the other side of the support ring.
