Description

Technical Field

[0001] This utility model relates to the field of filtration technology, and in particular to a filter assembly, valve device and connector device for use in ton container environments. Background Technology

[0002] In the new energy raw materials industry, tonnes (IBCs) are typically used as containers for the production and transportation of electrolytes (such as lithium hexafluorophosphate). These IBCs are equipped with inlet and outlet pipes connected to valves and fittings. During actual use, the electrolyte inevitably becomes contaminated with rust, electrolyte crystals, and other minute impurities from the pipes. To ensure electrolyte purity, IBCs usually have metal filters installed inside the valves and / or fittings. However, existing filters are relatively simple, made of fine steel wire, making them soft and difficult to press and fix. They are easily washed away or displaced by liquid pressure, creating gaps and failing to provide effective filtration. Utility Model Content

[0033] Reference Figure 1 , Figure 2 and Figure 3A filter assembly for use in a ton container environment includes a filter body 100 and a mounting housing 200. The filter body 100 includes a metal filter 110 and a metal edging 120. The metal edging 120 has a ring-shaped structure. The metal filter 110 is located inside the ring of the metal edging 120, and the outer peripheral edge of the metal filter 110 is connected and fixed to the inner ring of the metal edging 120. The mounting housing 200 has a ring-shaped structure and is fixedly connected to the metal edging 120. The metal filter 110 is located inside the ring of the mounting housing 200. The outer diameter of the mounting housing 200 is adapted to the inner diameter of the channel of the installation environment, and the mounting housing 200 can be inserted into the channel of the installation environment.

[0034] Understandably, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, the filter assembly is placed in the channel of the installation environment. The outer diameter of the mounting housing 200 is matched with the inner diameter of the channel of the installation environment, which can limit its relative channel rotation or displacement. By setting a metal edging 120 around the outer periphery of the metal filter 110, on the one hand, the metal edging 120 can cooperate with the metal filter 110 to form a structure similar to a badminton racket. The metal edging 120 provides support and tension for the metal filter 110, reducing the possibility of its deformation under liquid pressure. On the other hand, it also makes it easier for the mounting housing 200 to fix the relatively soft metal filter 110 by fixing it to the metal edging 120, reducing the possibility of the filter being washed away or displaced by liquid pressure and forming gaps. This facilitates subsequent installation and pressing, which is beneficial to ensure effective filtration of electrolyte in the ton container.

[0035] In practical applications, the metal filter 110 and the metal edging 120 can be made of stainless steel, and the mounting housing 200 can be made of polytetrafluoroethylene or other polymers. The specific structure of the mounting housing 200 can be set according to the actual use needs, which will not be described in detail here, but will be explained in detail below.

[0036] In some embodiments, the mounting housing 200 includes a first housing portion 210 and a second housing portion 220, the first housing portion 210 and the second housing portion 220 being located on both sides of the filter body 100, the first housing portion 210 and the second housing portion 220 being fixedly connected and clamping the fixed metal edging 120.

[0037] Understandably, such as Figure 2 , Figure 3 and Figure 4As shown, the first shell portion 210 is located on the front side of the filter body 100, and the second shell portion 220 is located on the rear side of the filter body 100. The first shell portion 210 and the second shell portion 220 are fixedly connected and clamp the fixed metal edging 120, thereby achieving the connection with the filter body 100. Its structure is simple, can achieve a good fixing effect, and is easy to use. In practical applications, in addition to the above structure, the mounting shell 200 can also be fixedly connected to the metal edging 120 through a snap-fit ​​structure. For example, a hook can be set to cooperate with the metal edging 120, or the mounting shell 200 can be integrally molded to cover the outside of the metal edging 120. The specific method can be adapted according to the actual use needs.

[0038] In some embodiments, the first shell portion 210 facing the metal edging 120 and the second shell portion 220 facing the metal edging 120 are both provided with receiving grooves 201. The receiving grooves 201 are in a ring shape, and the two sides of the metal edging 120 are respectively placed in the receiving grooves 201 of the first shell portion 210 and the receiving grooves 201 of the second shell portion 220.

[0039] Understandably, such as Figure 2 , Figure 3 and Figure 4 As shown, the rear side of the first shell 210 and the front side of the second shell 220 are both provided with receiving grooves 201. The receiving grooves 201 have a circular structure. When the first shell 210 and the second shell 220 are connected, the front and rear sides of the metal edging 120 are respectively placed in the receiving grooves 201 of the first shell 210 and the second shell 220. The inner wall of the receiving groove 201 fits with the inner side of the metal edging 120, thereby better fixing the filter body 100 and reducing the possibility of its displacement. In actual application, the receiving grooves 201 can be set according to the actual use needs.

[0040] In some embodiments, the second shell portion 220 is provided with a perimeter portion 221 extending toward the first shell portion 210. The perimeter portion 221 has an annular structure. The first shell portion 210 is located inside the annulus of the perimeter portion 221, and the outer peripheral wall of the first shell portion 210 cooperates with the inner sidewall of the annulus of the perimeter portion 221.

[0041] Understandably, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the front side of the second shell portion 220 is provided with a forward-extending perimeter portion 221. The perimeter portion 221 has a ring-shaped structure. When the first shell portion 210 is connected to the second shell portion 220, the first shell portion 210 is located inside the ring of the perimeter portion 221, and the outer peripheral wall of the first shell portion 210 mates with the inner side wall of the ring of the perimeter portion 221, thereby better covering the first shell portion 210. This helps to increase the mating area between the two and improve the stability and reliability of the mating. In practical applications, the perimeter portion 221 can be set according to actual usage needs.

[0042] In some embodiments, the first housing portion 210 and the second housing portion 220 are fixedly connected by a snap-fit ​​structure. It is understood that by setting the first housing portion 210 and the second housing portion 220 to be fixed by a snap-fit ​​structure, the connection method is simple, the assembly operation is relatively convenient, and it is easy to use in production. In practical applications, in addition to the above structure, the first housing portion 210 and the second housing portion 220 are fixedly connected by a threaded structure. For example, threads are provided on the inner sidewall of the ring of the perimeter portion 221 and the outer peripheral wall of the first housing portion 210 so that the two can be fixed by threaded engagement. Alternatively, the perimeter portion 221 and the first housing portion 210 can be fixed by an interference fit of a shaft hole. The specific configuration can be set according to actual usage needs.

[0043] In some embodiments, one of the first housing portion 210 and the second housing portion 220 is provided with a slot 202, and the other is provided with a corresponding insertion portion 211 that mates with the slot 202. The insertion portion 211 is provided with a snap-fit ​​notch 203, and the wall portion of the slot 202 is provided with a corresponding snap-fit ​​portion 222 that mates with the snap-fit ​​notch 203.

[0044] Understandably, such as Figure 2 , Figure 3 and Figure 4 As shown, slot 202 is located in the second shell portion 220. Slot 202 has a circular structure with the slot opening facing forward. Insertion portion 211 is located on the rear side of the first shell portion 210 and also has a circular structure. The outer peripheral side wall of insertion portion 211 is provided with a ring of locking notches 203. Correspondingly, the outer groove wall of slot 202 is provided with locking portions 222. In use, the first shell portion 210 is placed inside the ring of the surrounding portion 221 and insertion portion 211 is inserted into slot 202, so that locking portion 222 engages with locking notch 203, thereby achieving locking and fitting fixation between the first shell portion 210 and the second shell portion 220. Its structure is simple, the connection is stable and reliable, and it is easy to use. In practical applications, in addition to the above structure, the first shell portion 210 and the second shell portion 220 can also be locked together by hooks or buckles, etc., which can be set according to actual needs.

[0045] In some embodiments, the thickness of the mounting housing 200 along the axial direction is a preset dimension T, and the value of the preset dimension T ranges from 8mm to 12mm. It is understood that, as... Figure 3 As shown, by setting the preset size T to 8mm to 12mm (inclusive of the endpoint value), the possibility of the filter assembly flipping in the channel can be reduced by utilizing a thicker thickness. In practical applications, the preset size T can be 8mm, 10mm, or 12mm, and can be set accordingly based on actual usage needs.

[0046] In some embodiments, the mesh count M of the metal filter 110 ranges from 200 mesh ≤ M ≤ 230 mesh. It is understood that by setting the mesh count M of the metal filter 110 to between 200 and 230 mesh (inclusive), a larger mesh count results in a smaller pore size, achieving a better filtration effect and facilitating use. In practical applications, the mesh count M can be 200 mesh, 220 mesh, or 230 mesh, depending on the specific application requirements.

[0047] The valve device according to a second aspect of the present invention includes a filter assembly for use in a ton container environment according to the first aspect of the present invention described above.

[0048] According to the valve device of this utility model embodiment, by adopting the filter screen assembly used in the above-mentioned ton container environment, the possibility of the filter screen being washed away, deformed or displaced by liquid pressure and forming gaps is low, which is convenient for installation and fixation, and helps to ensure effective filtration of electrolyte in the ton container.
