Technical Field

[0001] The utility model belongs to the technical field of primary filter application, and particularly relates to an air-conditioning box paper frame filter and a filtering system using the same. Background Art

[0002] The primary filter acts as a pre-filter in the entire air purification system. It is usually made of a sturdy, moisture-proof cardboard frame, which is high-strength and not easily deformed.

[0003] G4 air conditioning filters are primary filters, primarily used to filter large particles and dust from the air, with a filtration efficiency generally ranging from 40% to 60%. Their primary function is to protect the heat exchanger and fan within the air conditioning system, preventing dust and impurities from accumulating and extending the service life of the equipment.

[0004] G4 grade filters are suitable for general household or commercial air conditioning systems, can meet daily air purification needs, and can also be used in pre-filtration systems in various places such as office buildings, shopping malls, airports, workshops and factories.

[0005] Timely replacement of the G4 air conditioner's primary filter ensures the extended life of the subsequent medium-efficiency and high-efficiency filters. This is especially true in environments with severe air pollution, such as paint shops, where paint spraying produces significant amounts of paint mist. Approximately 25% to 35% of the paint is released into the air, containing harmful substances such as toluene, chlorobenzene, and acetone. Primary filters are typically discarded as hazardous waste. Therefore, paper-frame primary filters, due to their cleanability, high quality, and affordability, are more suitable for these applications.

[0006] At present, with the increasing awareness of environmental protection and the demand for cost savings, the disposable use of the traditional G4-level air-conditioning primary filter must also be improved according to actual usage needs, such as replaceable foldable glass fiber filter elements and other components that can be easily disassembled and replaced.

[0007] Therefore, based on the above problems, the present invention provides an air-conditioning box paper frame filter and a filtering system using the same. Utility Model Content

[0025] Example 1

[0026] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The illustrated air conditioning box paper frame filter comprises a cardboard frame 100, a set of horizontal plates 101, screw grooves 102, a set of compression reinforcement nets 103, a circular fixing sleeve 104, a set of outer cardboard pressure plates 105, two sets of outer cardboard pressure plate through holes 106, air slots 107, four sets of bolts 108, and a folded glass fiber filter element 109.

[0027] The horizontal plates 101 are symmetrically arranged in the middle of the inner walls on both sides of the cardboard frame 100.

[0028] The screw grooves 102 are symmetrically arranged in the end faces of both ends of the horizontal plate 101.

[0029] The compression reinforcement net 103 and the outer cardboard pressing plate 105 are stacked on the surface of the horizontal plate 101 in sequence, and the screw groove 102, the circular fixing sleeve 104 and the outer cardboard pressing plate through hole 106 are aligned one by one.

[0030] The horizontal plate 101, the tightening reinforcement net 103, and the outer cardboard pressing plate 105 are fixed together by bolts 108 through screw grooves 102, circular fixing sleeves 104, and the outer cardboard pressing plate through holes 106.

[0031] The air duct 107 is provided in the outer cardboard pressing plate 105 and is located inside the through hole 106 of the outer cardboard pressing plate.

[0045] The above-mentioned design structure is simple in structure, convenient for mass production, reusable and has a long service life.

[0046] In addition, preferably, the bolts 108 include but are not limited to anti-static plastic bolts, which are light in weight, easy to assemble / disassemble, and durable.

[0047] The present invention provides a filtration system equipped with the aforementioned air conditioning box paper frame filter, which can be easily assembled or disassembled for use. The system also features a rational design and easy-to-manufacture components. Furthermore, the rational overall structural design provides high strength and resistance to deformation, thereby achieving a superior primary adsorption function.
