Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, and in particular to filter cartridge adapters and filtration equipment. Background Technology

[0002] In filtration equipment, either dual-opening or single-opening filter elements can be installed depending on different needs. However, due to structural differences, dual-opening and single-opening filter elements require different installation methods. In related technologies, filtration equipment only supports the direct installation of one type of filter element. When two types of filter elements with the same outer diameter are selected incorrectly, replacing them with another type of filter element requires modification of the pressure vessel and tube sheet, resulting in high costs.

[0030] like Figure 1 As shown, the filter element conversion connector according to the first aspect of the present invention includes a core rod 1, an adapter 2, and a filter element seat 3. One end of the core rod 1 is provided with a threaded interface 11. The adapter 2 is sleeved on the core rod 1, and the adapter 2 has a fluid channel 21 opened along the axial direction of the core rod 1. The filter element seat 3 is sleeved on the core rod 1, and the filter element seat 3 is connected to the side of the adapter 2 away from the threaded interface 11. The filter element seat 3 has an insertion channel 31 opened along the axial direction of the core rod 1. The insertion channel 31 is connected to the fluid channel 21 and is used to insert a single-opening filter element.

[0031] According to the filter element conversion connector of this utility model embodiment, the core rod 1, the adapter 2, and the filter element seat 3 are connected in a cooperative manner. The threaded interface 11 at one end of the core rod 1 and the adapter 2 are used to connect with the filter element installation position of the filtration equipment. In this way, the filter element seat 3 is adapted to install a single-opening filter element. When the original filter element installation position of the filtration equipment only supports the installation of a double-opening filter element, a single-opening filter element can be installed by installing the filter element conversion connector. Thus, the problem of compatibility installation between double-opening and single-opening filter elements can be solved by installing and removing the filter element conversion connector, achieving low-cost retrofitting.

[0032] Understandably, both the filter element holder 3 and the adapter 2 are made of 304 stainless steel and can be welded together to improve connection stability and prevent loosening. Simultaneously, the core rod 1 is welded to the adapter 2 to further enhance connection stability. The core rod 1, as an auxiliary connector, has a threaded interface 11 at one end for threaded connection with the filtration equipment. When the core rod 1 is rotated, the adapter 2 rotates accordingly to facilitate the installation of the filter element conversion connector. Of course, in other embodiments, the filter element holder 3 and the adapter 2 can also be an integrally formed structure to further improve connection stability.

[0033] Specifically, the filter element holder 3 is used to connect a single-opening filter element, and its structure differs from that of the adapter 2. According to one embodiment of the present invention, the filter element holder 3 has a connecting lug 32 at the end away from the adapter 2. The filter element holder 3 has connecting lugs 32 on both sides of the opening of its insertion channel 31. The two connecting lugs 32 form a U-shaped structure with their openings facing each other, which is used to improve the connection stability with the single-opening filter element.

[0034] The insertion channel 31 is connected to the fluid channel 21, which ensures that the fluid flow is not affected and no additional pressure loss is generated.

[0035] According to one embodiment of the present invention, the filter element conversion connector further includes a gasket 4, which is disposed on the adapter 2. The gasket 4 is used to seal against external components. It should be noted that the external components refer to the filter element installation position of the filtration equipment. After the gasket 4 and the filter element installation position of the filtration equipment are tightened, it ensures that there is no leakage at the connection and improves the sealing performance.

[0036] According to one embodiment of the present invention, a sealing ring groove 22 is provided on the inner wall of the fluid channel 21, and at least a portion of the gasket 4 is accommodated and confined within the sealing ring groove 22. It is understood that the sealing ring groove 22 is used to limit the installation of the gasket 4 to avoid the gasket 4 from shifting position, thereby improving the ease of installation and installation stability.

[0037] According to one embodiment of this utility model, the filter element adapter includes a mounting structure located at the end of the core rod 1 away from the threaded interface 11. The mounting structure has at least one limiting plane, which is parallel to the axis of the core rod 1. It is understood that workers can clamp the limiting plane to facilitate rotation of the core rod 1, preventing the core rod 1 from sliding relative to the installation tool, thus improving the ease of installation and disassembly.

[0038] According to one embodiment of the present invention, the installation structure is a nut 5. Thus, the operator can use a wrench or other installation tools to clamp the nut 5 and screw the core rod 1 so that the threaded interface 11 at one end of the core rod 1 can be connected to the filter equipment.

[0039] According to one embodiment of the present invention, the nut 5 is welded to the core rod 1 to improve the connection stability.

[0040] The filtration device according to a second aspect embodiment of the present invention includes a device body, a filter element, and the aforementioned filter element conversion connector. The filter element conversion connector is connected to the device body, and the filter element is disposed on the filter element conversion connector. For example, the filter element is a single-opening filter element. When the filtration device needs to be switched to a double-opening filter element, the filter element conversion connector can be removed, and the double-opening filter element can be installed into the filtration device.

[0041] The filtration device according to the present invention includes the above-mentioned filter element conversion connector, and therefore has all the technical effects of the above-mentioned filter element conversion connector, which will not be repeated here.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
