Description

Technical Field

[0001] This utility model relates to the field of air conditioning unit technology, and in particular to a cone-shaped installation device for an air conditioning unit cartridge filter. Background Technology

[0002] In the field of air conditioning units, especially in special air-conditioning environments such as cigarette factories and welding workshops, the transported gas often contains substances such as tobacco and welding fumes. Therefore, air conditioning units must be equipped with suitable filters to ensure that service areas such as workshops meet production process requirements. Cartridge filters are an ideal choice for air conditioning units in service areas such as cigarette factories and welding workshops due to their high efficiency, long service life, easy cleaning, and reusability (including multiple washes). They also possess characteristics such as anti-sedimentation, anti-delamination, moisture resistance, acid and alkali resistance, and oxidation resistance. To achieve better filtration effects, reduce air resistance, and save operating costs, the cartridges adopt a double-cylinder structure design of column and cone types. Because the stacked length of the cartridges is relatively long, the installation device must have sufficient mechanical strength and processing precision. When using conventional installation methods, not only is it difficult to guarantee strength and airtightness, but there are also problems such as inconvenience in installation and disassembly. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a conical installation device for air conditioning unit cartridge filters.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A conical mounting device for an air conditioning unit cartridge filter includes a top disc, hexagonal bolts, inclined support rods, fixing rods, internal hexagonal screws, flat washers, and spring washers, and is composed of round steel pipes. The inclined support rods are distributed in an isosceles triangle and welded into a conical structure, with hexagonal bolts welded to their ends.

[0006] Preferably, the top disc is made of steel, with a hole at the center point and a hexagonal bolt welded thereon. The threads of the hexagonal bolt face outwards, and the hexagonal head of the hexagonal bolt faces inwards. The top disc has three through holes evenly distributed for positioning and welding when welding with the diagonal support.

[0007] Preferably, the hexagonal bolt is a standard steel bolt.

[0008] Preferably, the inclined support rod is made of round steel pipe, one end of the inclined support rod is welded to the top disc, and the other end of the inclined support rod is welded with an internal hexagon screw.

[0009] Preferably, the fixing rod is made of round steel pipe, and the fixing rod comes in three length specifications.

[0010] Preferably, the hex socket screw, flat washer, and spring washer are standard parts, and the hex socket screw is welded to the inclined support rod.

[0011] This utility model has the following beneficial effects:

[0012] 1. This utility model uses a special tooling mold for positioning during the welding process, ensuring precise positioning of each connection point and avoiding welding deformation due to misalignment, which could affect strength or cause installation difficulties.

[0013] 2. The inclined support rod and fixing rod in this utility model are made of round steel pipe with a smooth surface to avoid scratching operators and to avoid affecting the filtration effect due to damage to the filter cartridge.

[0014] 3. The top of this utility model adopts a disc design, which is convenient for welding with hexagonal bolts. It also serves as a limit for the column-type filter cartridge + cone-type filter cartridge filter, and can make the filter cartridge and the filter cartridge frame assembly tightly connected, reducing air leakage.

[0015] 4. In use, this utility model employs three diagonal support rods arranged in an isosceles triangle, and nine fixing rods of three different lengths are evenly distributed on the diagonal support rods and fixed by welding to ensure the mechanical strength of the entire device.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-2This invention relates to a conical installation device for an air conditioning unit cartridge filter. The complete cartridge filter system mainly consists of a cartridge frame assembly, a conical installation device, a columnar cartridge + conical cartridge filter, and a handle locking device. The conical installation device comprises a top disc 1, hexagonal bolts 2, a diagonal support rod 3, a fixing rod 4 (in three lengths), internal hexagonal screws 5, a flat washer 6, and a spring washer 7. This invention uses a special tooling mold for positioning. The diagonal support rod 3, composed of three round steel pipes, is welded into a conical structure in an isosceles triangle configuration, with hexagonal bolts 2 welded to the ends. A handle locking device is used, allowing for the disassembly and assembly of the cartridge filter without any special tools. This solves the problems of deformation and air leakage caused by insufficient installation strength in cartridge filters, while also shortening the installation and disassembly time, ensuring that the air conditioning unit can be put into use in a short time.

Three through holes are evenly distributed on the top disc 1, serving as positioning and facilitating welding of the diagonal support rod 3. The hexagonal bolts 2 are standard steel bolts, with the threads facing outwards and the hexagonal head facing inwards during welding. After the cartridge filter is installed, the handle locking device is attached to the hexagonal bolts and tightened for easy and quick locking of the cartridge filter. The diagonal support rod 3 is made of round steel tubing, with one end welded to the top disc 1 and the other end welded to an internal hexagonal screw 5, with the threads facing outwards and the hexagonal head of the screw facing inwards during welding. During installation, the diagonal support rod 3 is connected to the cartridge frame assembly using bolts.
