Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter. Background Art

[0002] In order to ensure the quality of aviation fuel products, aviation fuel production, storage and transportation equipment must be equipped with aviation fuel filters to filter out impurities larger than 3μm to meet aviation fuel technical indicators and ensure aviation safety.

[0003] refer to Figure 1 , the filter 1' in the prior art is usually fixed on the filter tray 6' below by the gasket, the end cover 2', the nut 3' and the screw 5' in the middle of the filter element 4', and only the lower end is fixed. At the same time, since the main body of the filter element 4' is relatively long, there is a circular cavity between the filter element 4' and the screw 5'. Under the impact of the oil product with a high flow rate, the oil product impacts the filter element 4' from the bottom to the top, and the filter element 4' will have a large shake. At the same time, because of the screw 5' in the middle, it will shake back and forth; during the shaking process, its upper end will contact with the nut 3' The friction between the filter element 4' and the filter 1' causes damage to the filter element 4'. In addition, during maintenance, it is occasionally found that the filter element 4' collides with the inner wall of the filter 1', resulting in friction and blackening of the inner wall. Preliminary research shows that this is because the outer circle of the filter element 4' is closer to the inner wall of the filter 1', and under the high-speed impact of the oil, only the lower section of the filter element 4' is fixed, resulting in greater shaking. Under the friction between the upper end of the filter element 4' and the inner wall of the filter 1', the friction and blackening of the inner wall occur, which is very dangerous to the safety of the oil.

[0023] refer to Figures 2 to 4 , the utility model embodiment discloses:

[0024] A filter, comprising a filter body 1, a connecting plate 2 arranged in the filter body 1, a plurality of connecting rods 3 arranged on the connecting plate 2, and a plurality of filter elements 4 arranged on the connecting plate 2, wherein the connecting rod 3 passes through the filter element 4 upward, and further comprising a fixing plate 5, wherein a fixing hole 6 is provided on the fixing plate 5, and the upper end of the connecting rod 3 passes through the fixing hole 6 and is provided with a fastener 7, wherein the fastener 7 is used to limit the fixing plate 5 to the upper end of the filter element 4, and each of the connecting rods 3 shares the same fixing plate 5 to limit the distance between the upper ends of each of the connecting rods 3; specifically, in this embodiment, the filter element 4 (filter cartridge) is sleeved on the connecting rod 3, and a threaded hole is provided on the upper end of the connecting rod 3 , the upper end of the connecting rod 3 passes through the fixing plate 5, so that the fixing plate 5 is installed on the filter element 4, and then fixed by the fastener 7 (locking bolt), that is, a fixing plate 5 is also provided between the upper end of the filter element and the fastener 7 to prevent the fastener 7 from directly contacting the filter element 4 and causing damage to the upper end of the filter element 4; and the connecting rods 3 share the same fixing plate 5 (that is, in this embodiment, only one fixing plate 5 is provided), so that the upper ends of the connecting rods 3 are fixed (that is, the distance between the upper ends of the connecting rods 3 is limited), and at the same time, the lower ends of the connecting rods 3 are fixedly connected to the connecting plate 2, thereby preventing the shaking between the connecting rods 3 and the collision of the filter element 5 with the inner wall of the filter body 1.

[0025] During maintenance, if it is found that one of the filter elements 4 needs to be replaced, all the fasteners 7 need to be removed before the fixed plate 5 can be removed, and finally the filter element 4 that needs to be removed can be removed, which is time-consuming and laborious; therefore, in this embodiment, the fixed plate 5 is composed of at least two fixed units 501, and the side walls of each of the fixed units 501 abut against each other to assemble into the fixed plate 5; when removing the filter element 4, only the fixed unit 501 connected to the filter element 4 needs to be removed, thereby reducing the disassembly process and improving efficiency.

[0026] In order to prevent relative displacement or collision between the fixing units 501, a connecting mechanism is provided between the fixing units 501, and the connecting mechanism is used to connect and fix the fixing units 501 that are abutting against each other; the connecting mechanism includes a connecting platform 502 provided at one end of each fixing unit 501, and each connecting platform 502 abuts against each other. A fixing piece 8 is provided on the connecting platform 502, and the fixing piece 8 is detachably connected to each connecting platform 502.

[0027] Specifically, as shown in the figure, the fixed disk 5 in this embodiment is a disc-shaped fixed disk 5, and the connecting platforms 502 abut against each other to complement each other to form a cylindrical assembly, the cylindrical assembly is located at the center of the fixed disk 5, and the side wall of the cylindrical assembly is provided with an external thread. The fixing member 8 is a fixing ring, and the inner side of the fixing ring is provided with an internal thread that matches the cylindrical assembly; the fixed disk 5 can be connected and fixed by means of threaded connection; the structure is simple and easy to disassemble and assemble.

[0028] The connection mechanism further includes a card slot 12 formed on the fixing unit 501 . The card slot 12 is located on the side walls of the fixing units 501 that are mutually abutted and connected. A card block 9 is detachably disposed in the card slot 12 .

[0029] Specifically, the number of the fixed disks 5 is 2 or 3.

[0030] When several upper ends are fixed by the fixing plate 5, it is inconvenient to observe each filter element 4 during maintenance because the fixing plate 5 blocks each filter element 4 from the upper end; therefore, at least one observation hole 10 is opened on the fixing plate 5 to facilitate the staff to observe the filter element 4 from the upper end during normal maintenance.

[0031] A mounting groove is disposed at the lower end of the fixing plate 5 and located around the fixing hole 6 , and an elastic pad 11 is disposed between the fixing plate 5 and the filter element 4 and located in the mounting groove.

[0032] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the implementation cases of the utility model.
