Abstract
Description
Technical Field
[0001] This utility model relates to the field of oil separator filter element disassembly and maintenance technology, and more specifically, to a filter element packing material that is easy to maintain and replace. Background Technology
[0002] With the rapid development of national modernization, oil separators have been widely used in the petroleum and petrochemical industry due to their advantages such as high efficiency, intelligence and environmental protection. However, the filter packing in existing oil separator devices still has shortcomings in terms of the convenience of maintenance, which limits its further development and application.
[0003] The filter element in the oil separator needs to be disassembled, replaced, or maintained. The specific procedure is as follows:
[0004] After the oil separator stops operating, the medium inside the tank is vented until it reaches the bottom. Then, the manhole is opened for ventilation. At least two replacement personnel, after taking safety precautions, must enter the tank through the manhole. Inside, they disassemble the filter cartridges one by one and pass them to the installation personnel outside the tank through the manhole. The installation personnel outside then pass unused filter cartridges to the installation personnel inside the tank through the manhole for installation. After the filter cartridges are installed, the installation personnel inside the tank leave through the manhole, and finally, the manhole is closed. However, the filter cartridges and filter tubes are welded together, making disassembly inconvenient. In summary, the ease of filter cartridge replacement needs improvement. Utility Model Content
[0005] The purpose of this invention is to solve the problems mentioned in the background art and to propose a filter cartridge that is easy to maintain and replace.
[0006] The technical solution adopted by this utility model to solve its technical problem is:
[0007] A filter cartridge packing material that is easy to maintain and replace includes a filter cartridge tube and a filter cartridge. The filter cartridge tube has several sets of leakage holes on its circumference that connect to its interior. It also includes a screw, a positioning plate, a first mounting plate, a second mounting plate, a strip steel, a pipe, a first through hole, a second through hole, a nut, and several fasteners.
[0008] The screw is fixed to one end of the filter element tube, and a positioning plate is fixed on the filter element tube;
[0009] Several strip steels are fixed circumferentially between the first mounting plate and the second mounting plate, and the axial position of the second mounting plate is limited by the positioning plate.
[0010] Several pipes are fixed to the inner wall of the steel strip and are spaced apart;
[0011] The first through hole is formed on the first mounting plate, and the first through hole mates with the screw.
[0012] The second through hole is opened on the second mounting plate, and the second through hole and the inner wall of the pipe are in contact with the filter tube;
[0013] The nut is threadedly connected to the screw.
[0014] The filter element covering all leakage holes is fitted onto the filter element tube and locked by multiple sets of fasteners.
[0015] Furthermore, the fastener is a clamp.
[0016] Furthermore, handles are symmetrically fixed on the first mounting plate.
[0017] The above solution allows for easier assembly of the filter cartridge, pipe, and through-hole using a handle.
[0018] Furthermore, the diameter of the first through hole is larger than the diameter of the screw, and a washer is fixed on the outer side of the first mounting plate, with the nut in contact with the washer.
[0019] In the above scheme, since the size of the first through hole is larger than that of the screw, the connection stability between the filter tube and the first mounting plate can be further improved by adding a gasket.
[0020] Furthermore, both the strip steel and the pipe are made of stainless steel.
[0021] Furthermore, a rubber layer is fixedly provided on the positioning plate.
[0022] In the above scheme, both the strip steel and the pipe are made of stainless steel to resist corrosion, and the rubber pads can prevent the second mounting plate from making hard contact with the positioning plate and causing wear.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] Compared to existing technologies, this device allows for easy disassembly, replacement, or maintenance of the filter element. Simply wait until the liquid level in the tank drops below the bottom plate of the filter element inlet, then first disconnect the screw and nut. Next, pull the handle to the left to separate the mounting plate from the filter element tube. The filter element, along with the mounting plate, is then pulled out of the tank through the inspection port. Afterward, release the locking mechanisms of the multiple clamps to replace the filter element. This allows for filter element replacement through the tank's inspection port without entering the tank. Furthermore, the filter element and filter element tube are easily connected by multiple clamps, eliminating the need for manual welding or other procedures inside the tank, significantly reducing safety hazards. In summary, the maintenance and disassembly process for the oil separator filter element is significantly more convenient, resulting in better oil separator performance. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:
[0032] like Figures 1 to 4 As shown, a filter cartridge packing material that is easy to maintain and replace includes a filter cartridge tube 1 and a filter cartridge 2. The filter cartridge tube 1 has several sets of leakage holes 3 connected to its interior around its circumference. It also includes a screw 4, a positioning plate 5, a first mounting plate 6, a second mounting plate 7, a strip steel 8, a pipe 9, a first through hole 10, a second through hole 11, a nut 12, and several fasteners 13.
[0033] The screw 4 is fixed at one end of the filter tube 1, and the positioning plate 5 is fixed on the filter tube 1;
[0034] A plurality of strip steels 8 are fixed circumferentially between the first mounting plate 6 and the second mounting plate 7, and the axial position of the second mounting plate 7 is limited by the positioning plate 5.
[0035] Several pipes 9 are fixed on the inner wall of the strip steel 8 and are spaced apart;
[0036] The first through hole 10 is formed on the first mounting plate 6, and the first through hole 10 is engaged with the screw 4;
[0037] The second through hole 11 is opened on the second mounting plate 7, and the second through hole 11 and the inner wall of the pipe 9 are both in contact with the filter tube 1.
[0038] Nut 12 is threadedly connected to screw 4;
[0039] The filter element 2, covering all leakage holes 3, is fitted onto the filter element tube 1 and locked in place by multiple sets of fasteners 13.
[0040] (Specifically, fastener 13 uses a clamp).
[0041] In a further optimization of the embodiment of this utility model, both the strip steel 8 and the pipe 9 are made of stainless steel, and a rubber layer (not shown in the figure) is fixed on the positioning plate 5. Both are made of stainless steel to resist corrosion, and the rubber pad can prevent the second mounting plate 7 from making hard contact with the positioning plate 5 and causing wear.
[0042] Further optimizations to the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, handles 14 are symmetrically fixed on the first mounting plate 6.
[0043] Further optimizations to the embodiments of this utility model, such as... Figure 1 As shown, the diameter of the first through hole 10 is larger than the diameter of the screw 4, and a washer 15 is fixed on the outside of the first mounting plate 6, with the nut 12 in contact with the washer 15.
[0044] The working process of this utility model:
[0045] The filter element tube 1 is initially welded to the oil separator (the oil separator is not shown in the figure and is existing technology, so no improvement is made). First, the filter element 2, which is sleeved on the outside of the filter element tube 1, is locked in place using multiple clamps and bolts (as shown in the instruction manual). Figure 1 As shown in the diagram, this eliminates the need for welding, making subsequent disassembly, replacement, and maintenance of the filter element 2 convenient.
[0046] Then, by grasping the first mounting plate 6 with handle 14, the second mounting plate 7 connected to the first mounting plate 6 is positioned to the left of the filter element tube 1. It then moves from left to right so that the filter element tube 1 passes through the second through hole 11 and fits against the inner wall of several pipes 9 for accurate positioning. When the second mounting plate 7 contacts the positioning plate 5, the axial position of the filter element 2 is immediately defined. This ensures that the filter element 2 completely covers all leakage holes 3, thus preventing a small number of leakage holes 3 from being exposed and causing treated water to be discharged directly from the leakage holes 3 without being treated by the filter element 2. Since there are gaps between the multiple steel strips 8 and the multiple pipes 9 (as shown in the instruction manual),... Figure 4 As shown in the diagram, the treated water, after being filtered by the filter element 2, can sequentially pass through the gaps between the strip steel 8, the gaps between the pipes 9, and the leakage hole 3, and finally flow into the filter element tube 1 and be discharged.
[0047] At the same time, the screw 4 smoothly passes through the first through hole 10, and then the filter tube 1 and the first mounting plate 6 are fixedly connected by the nut 12. (It should be noted that since the size of the first through hole 10 is larger than the screw 4, the connection stability between the filter tube 1 and the first mounting plate 6 can be further improved by adding a washer 15.)
[0048] When filter element 2 needs to be disassembled, replaced, or maintained, simply wait until the liquid level in the tank drops below the horizontal height of the filter element inlet bottom plate, then first disconnect the connection between screw 4 and nut 12, and then pull handle 14 to the left to separate the mounting plate from the filter element tube 1. Filter element 2, along with the mounting plate, will then be pulled out of the tank through the inspection port. After that, the locking of multiple clamps can be released in sequence to replace filter element 2. In this way, the filter element packing can be replaced through the inspection port of the tank without entering the tank. At the same time, filter element 2 and filter element tube 1 are connected by multiple clamps, making disassembly convenient. There is no need for manual entry into the tank for welding or other procedures, which significantly reduces safety hazards. In summary, the maintenance and disassembly process of oil separator filter element 2 is significantly more convenient, and the oil separator performs better.
[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
