Description

Technical Field

[0001] This utility model relates to the field of silicone oil production technology, and in particular to a filtration device and a silicone oil storage tank. Background Technology

[0002] Silicone oil typically refers to linear polysiloxane products that remain liquid at room temperature. It is generally classified into two categories: methyl silicone oil and modified silicone oil. The most commonly used silicone oil is methyl silicone oil, also known as ordinary silicone oil. Before filling, silicone oil needs to be stored in a silicone oil storage tank. A filling structure is installed at the discharge pipe of the storage tank to fill the silicone oil into finished containers (drums, bottles, etc.). Inevitably, some impurities will be present in the silicone oil stored in the storage tank. To prevent these impurities from being filled into the finished containers, a filtration device needs to be installed between the discharge pipe and the filling structure to filter out these impurities. However, existing filtration devices used in silicone oil storage tanks have the problem that the filter layers (filter screens, filter cartridges, filter plates, etc.) are not easily disassembled for cleaning.

[0040] Reference Figures 1 to 5 As shown, a filtration device according to an embodiment of the present invention includes: a filter box 100, a filter section 200, and a locking mechanism 300.

[0041] The filter box 100 has a rectangular box structure. An inlet pipe 110 and an outlet pipe 120 are respectively provided at both ends of the filter box 100 along its length. An installation port 101 is provided through the side wall of the filter box 100, and the through direction of the installation port 101 is perpendicular to the length direction of the filter box 100.

[0042] The filter section 200 includes a frame 210, a filter screen 220, and a sealing plate 230. The frame 210 passes through the mounting port 101 and extends into the filter box 100. The frame 210 has a rectangular structure, and obviously, the frame 210 can pass through the mounting port 101. The filter screen 220 is installed on the frame 210 and is used to filter the liquid flowing from the inlet pipe 110 to the outlet pipe 120. The sealing plate 230 is fixedly connected to the frame 210 and is located on the outside of the filter box 100. The sealing plate 230 is used to close the mounting port 101 to prevent the liquid inside the filter box 100 from flowing out.

[0043] The locking mechanism 300 includes a rotating part 310 and a locking part. The rotating part 310 is rotatably disposed on the outer side wall of the filter box 100, and the rotation axis of the rotating part 310 is parallel to the through direction of the mounting port 101. The locking part is movably and adjustably disposed on the rotating part 310 along the through direction of the mounting port 101. The rotating part 310 has at least a first state and a second state during rotation. In the first state (e.g....) Figure 1 and Figure 3 As shown), the locking part at least partially blocks the movement path of the sealing plate 230 in the through direction of the mounting port 101, and in this state, the locking part can be adjusted to press the sealing plate 230 against the filter box 100 or to separate from the sealing plate 230 in the through direction of the mounting port 101. In the second state (as shown) Figure 2 As shown), the rotating part 310 and the locking part avoid the movement path of the sealing plate 230 in the through direction of the mounting port 101. At this time, the filter part 200 can be pulled out from the mounting port 101 for cleaning or replacement.

[0044] In this embodiment of the filter device, when installing the filter section 200, the rotating part 310 can be rotated and adjusted to the second state first. Then, the frame 210 of the filter section 200 is inserted into the mounting port 101 until the sealing plate 230 abuts against the filter box 100 and closes the mounting port 101. Then, the rotating part 310 is rotated and adjusted to the first state. Then, the locking part is adjusted relative to the rotating part 310 so that the locking part moves toward the sealing plate 230 and abuts against the outer end face of the sealing plate 230, so as to press the sealing plate 230 against the filter box 100, thereby locking the filter section 200 onto the filter box 100. When it is necessary to disassemble the filter section 200 for cleaning or replacement, the locking part can be adjusted away from the filter box 100 first to separate the locking part from the sealing plate 230. Then, the rotating part 310 is rotated and adjusted to the second state. Then, the filter section 200 can be pulled out from the mounting port 101. The disassembly and assembly of the filter section 200 is very convenient.

[0045] It is conceivable that both the input pipe 110 and the output pipe 120 are provided with flange structures for connecting to other structures. For example, when the filter device is applied to a silicone oil storage tank, the flange structure of the input pipe 110 can be used to connect to the discharge pipe of the silicone oil storage tank, and the flange structure of the output pipe 120 can be used to connect to the filling structure.

[0046] It is conceivable that the sealing plate 230 and the frame 210 can be connected by welding or fasteners, or they can be integrally molded.

[0047] It is conceivable that, in order to ensure sufficient locking force, a filter section 200 may be provided with multiple locking mechanisms 300, and the multiple locking mechanisms 300 are evenly arranged.

[0048] It is conceivable that, in order to facilitate the removal of the filter section 200, a handle 233 can be provided on the outer end face of the sealing plate 230.

[0049] Reference Figure 1 and Figure 3 As shown, in some embodiments of this utility model, multiple filter sections 200 are spaced apart along the direction from the input pipe 110 to the output pipe 120, and the filter pore diameters of the filter screens 220 of the multiple filter sections 200 decrease sequentially. Each filter section 200 is independently configured, meaning that the assembly and disassembly of each filter section 200 do not interfere with each other. The mounting ports 101 correspond one-to-one with each filter section 200, meaning one filter section 200 is installed at each mounting port 101. Clearly, each filter section 200 is individually equipped with a locking mechanism 300.

[0050] It is conceivable that impurities in liquid materials (such as silicone oil) that need to be filtered by a filtration device often vary in size. In this embodiment, a multi-stage filtration section 200 with progressively smaller pore diameters is designed along the direction from the input pipe 110 to the output pipe 120, which can form a gradient filtration structure. This arrangement realizes the step-by-step filtration of liquid materials. Large particles of impurities are first intercepted by the upstream filter screen 220 with larger pores, medium particles are captured by the midstream filter screen 220, and small particles are removed by the downstream filter screen 220 with the finest pores. This progressive filtration method can effectively avoid the problem of a single filter screen 220 becoming clogged quickly due to bearing the entire filtration load, thereby effectively improving the filtration efficiency, extending the overall service life of the filtration device, and extending the maintenance cycle. On the other hand, each filter section 200 is set independently, so that the disassembly and installation of each filter section 200 do not interfere with each other. When it is necessary to disassemble a filter section 200 for cleaning or replacement, it can be operated individually through the corresponding installation port 101 without disassembling all filter sections 200. Especially for the downstream filter screen 220 with smaller filter holes that is more prone to clogging, the independent maintenance design makes maintenance operations more convenient and efficient.

[0051] Reference Figure 3 As shown, in some embodiments of this utility model, the locking part is provided with a locking rod 320. The outer peripheral wall of the locking rod 320 is provided with an external thread and is threadedly installed on the rotating part 310. The central axis of the locking rod 320 is parallel to the through direction of the mounting port 101. By screwing the locking rod 320, the locking rod 320 can be moved relative to the rotating part 310 along the through direction of the mounting port 101, and the adjustment operation is very convenient.

[0052] Furthermore, to facilitate the operator in turning the locking rod 320, an operating handle is fixedly provided at the end of the locking rod 320 away from the filter box 100.

[0053] Reference Figure 3 As shown, in some embodiments of this utility model, a mounting nut 330 is fixed on the rotating part 310 for mounting the locking rod 320. Compared with the solution of directly threading the rotating part 310, this embodiment uses an independent mounting nut 330, which not only improves the anti-loosening effect, but also significantly improves the wear resistance and fatigue resistance of the thread, thereby extending the service life of the locking mechanism 300.

[0054] It is conceivable that the mounting nut 330 can be a welded nut, and welded and fixed to the rotating part 310; for example, in some embodiments, the rotating part 310 is provided with a welding hole, and the mounting nut 330 is partially embedded in the welding hole and welded and fixed to the rotating part 310. Obviously, the welding hole can allow the locking rod 320 to pass through.

[0055] Of course, to further improve structural strength, a mounting nut 330 can also be welded on each of the opposite sides of the extension direction of the welding hole.

[0056] In addition, it is conceivable that the rotating part 310 can be a plate-like structure with sufficient thickness to ensure its structural strength.

[0057] Reference Figure 3 and Figure 4 As shown, in some embodiments of this utility model, the outer end face of the sealing plate 230 is provided with a positioning hole 231. The positioning hole 231 is used for the insertion of a portion of the locking rod 320 to restrict the rotation of the rotating part 310. Through the cooperative design of the positioning hole 231 and the locking rod 320, the precise positioning and locking of the rotating part 310 is achieved. When the locking rod 320 is partially inserted into the positioning hole 231, the arbitrary rotation of the rotating part 310 in the circumferential direction can be effectively restricted, improving the anti-loosening effect and enhancing the reliability of the locking mechanism 300.

[0058] Reference Figure 3As shown, in some embodiments of this utility model, the inner end face of the sealing plate 230 is provided with a sealing ring groove 232, and a first sealing ring 240 is embedded in the sealing ring groove 232. The outer side wall of the filter box 100 is provided with annular protrusions 102 distributed circumferentially along the mounting port 101. The annular protrusions 102 are used to embed into the sealing ring groove 232 and abut against the first sealing ring 240, thereby providing a tight sealing effect through the first sealing ring 240 to ensure that the liquid material in the filter box 100 will not flow out.

[0059] Reference Figure 3 and Figure 5 As shown, in some embodiments of this utility model, the two inner sidewalls of the filter box 100 are respectively provided with limiting grooves 103 for the two opposite ends of the frame 210 to be embedded. The extending direction of the limiting grooves 103 is parallel to the through direction of the mounting port 101. With this arrangement, the limiting grooves 103 can provide stable support for the frame 210 and effectively prevent the frame 210 from being deformed and damaged by water flow impact.

[0060] Reference Figure 3 As shown, in some embodiments of this utility model, an installation shaft 130 is provided on the outer wall of the filter box 100. The installation shaft 130 is located on the periphery of the sealing plate 230. The installation shaft 130 includes a first shaft segment, a second shaft segment, and a third shaft segment whose diameter decreases sequentially in the direction away from the filter box 100. A limit nut 140 is threadedly installed on the third shaft segment. The rotating part 310 is provided with a sleeve hole and is rotatably sleeved on the second shaft segment through the sleeve hole. The rotating part 310 is axially limited by the stepped surface between the first shaft segment and the second shaft segment and the limit nut 140, thereby realizing the rotational installation of the rotating part 310. The structure is simple and the rotating part 310 is easy to disassemble and assemble.

[0061] Reference Figure 3 and Figure 5 As shown, in some embodiments of this utility model, the filter box 100 includes a box body 104 and an end cap 105. One end of the box body 104 along its length is provided with an input pipe 110, and the other end is open to form a cleaning port. The end cap 105 is detachably connected to the end of the box body 104 away from the input pipe 110, and the end cap 105 is used to close the cleaning port; wherein, the output pipe 120 is provided on the end cap 105. In this embodiment, the filter box 100 is divided into a box body 104 and an end cap 105. By removing the end cap 105 and all the filter parts 200, the interior of the filter box 100 is completely exposed, facilitating thorough manual or mechanical cleaning of the interior of the filter box 100 from the cleaning port.

[0062] It is conceivable that, to facilitate the positioning and installation of the end cap 105, a positioning ring 106 is provided on the inner end face of the end cap 105, and the positioning ring 106 is embedded in the housing 104. In addition, to ensure sealing performance, a second sealing ring 150 is provided on the outer sleeve of the positioning ring 106, and the second sealing ring 150 is sandwiched between the end cap 105 and the housing 104.

[0063] It is conceivable that the housing 104 and the cover can be fixed by bolts to facilitate disassembly and assembly. For example, an outwardly protruding annular connecting plate can be provided at one end of the housing 104 near the end cover 105, and bolts can be passed between the connecting plate and the end cover 105 for connection.

[0064] This utility model embodiment also proposes a lubricating oil storage tank, which includes a tank body and a filtration device from any of the above embodiments. The tank body defines a storage cavity for storing silicone oil. A discharge pipe communicating with the storage cavity is provided at the bottom of the tank body. An input pipe 110 is detachably connected to the outlet end of the discharge pipe. For example, flange structures can be provided on both the discharge pipe and the input pipe 110 for connection. Thanks to the improvements in the filtration device described above, the silicone oil storage tank of this embodiment has the same technical effects as the aforementioned filtration device, which will not be elaborated further here.
