Description

Technical Field

[0001] This utility model relates to the field of water-absorbing filter element technology, and in particular to a water-absorbing filter element for unloading oil tankers. Background Technology

[0002] Water-absorbing filters are used when unloading oil from tank trucks to prevent moisture from contaminating the oil and ensuring its quality and stability. Moisture can come from various sources, such as condensation of water vapor during transportation or inherent moisture in the oil itself. Moisture can cause oil corrosion, reduce fuel combustion efficiency, and may even damage equipment.

[0003] Water-absorbing filter elements typically use highly absorbent materials such as molecular sieves, activated carbon, and special synthetic resins. These materials effectively absorb moisture from the oil, thus preventing water from entering the oil system. When tank trucks unload oil, such filter elements are usually installed before the oil flows into the storage tank to ensure that the oil is not contaminated during the unloading process.

[0004] In traditional technologies, the water-absorbing filter elements used during oil tanker unloading are mostly fixedly connected inside the outer casing, requiring disassembly of the casing or complex operations to replace them. This design not only increases maintenance complexity but also prolongs replacement time and labor costs. Because the filter element is typically located in a relatively enclosed area, operators face challenges in accessing the filter element due to limited space, potentially impacting work efficiency and increasing human error risks. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a water-absorbing filter element for unloading oil tankers, aiming to improve the problems of low filter element replacement efficiency and inconvenient operation caused by the fact that most water-absorbing filters used in oil tanker unloading are connected to the inside of the shell by a fixed structure in traditional technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water-absorbing filter element for unloading oil tankers, comprising a housing, a filter rod slidably connected inside the housing, a locking hole on both sides of the filter rod, a locking mechanism on the outside of the housing for quickly replacing the filter rod, and a separation mechanism at both the upper and lower ends of the filter rod for separating oil and water.

[0007] The engaging mechanism includes two mounting shells, with opposite sides of the two mounting shells fixedly connected to the outside of the outer shell. Springs are fixedly connected inside the two mounting shells, and limit blocks are fixedly connected to opposite sides of the two springs. Pins are fixedly connected inside the two limit blocks, and the pins penetrate the outside of the outer shell and engage with the locking hole.

[0008] As a further description of the above technical solution:

[0009] A fixing box is fixedly connected to the top of the mounting shell, a sliding plate is slidably connected inside the fixing box, a baffle plate is fixedly connected to the bottom of the sliding plate, and the bottom of the baffle plate abuts against the top of the limiting block.

[0010] As a further description of the above technical solution:

[0011] The limiting block is slidably connected inside the mounting housing, and the pin passes through both ends of the mounting housing.

[0012] As a further description of the above technical solution:

[0013] A handle is fixedly connected to the side of the pin away from the limiting block.

[0014] As a further description of the above technical solution:

[0015] A sealing ring is provided on the top of the outer casing.

[0016] As a further description of the above technical solution:

[0017] The separation mechanism includes two connecting seats, with the opposite sides of the two connecting seats fixedly connected to the top and bottom of the filter rod, respectively.

[0018] As a further description of the above technical solution:

[0019] A toothed ring is rotatably connected to the side of the connecting seat away from the filter rod, and a separator housing is rotatably connected to the side of the toothed ring away from the connecting seat.

[0020] As a further description of the above technical solution:

[0021] The separator housing has several disturbance plates installed inside.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, an oil inlet pipe and an oil outlet pipe are connected to the upper and lower ends of the outer shell, respectively. After the oil and water are separated by the separation mechanism, the water is absorbed by the filter rod, and the oil is discharged from the oil outlet pipe through the filter rod. When the filter rod needs to be replaced, the handle is pulled outward to pull the pin rod, which causes the limit block to compress the spring and retract into the mounting shell. The baffle plate automatically falls due to gravity and blocks the limit block, preventing it from moving. At this time, the filter rod can be taken out. After replacing the new filter rod, the baffle plate is pulled up by the sliding plate. The spring rebound force pushes the limit block, which in turn drives the pin rod to re-engage with the locking hole and fix it. This achieves the effect of quickly replacing the filter rod through the locking mechanism, improving the efficiency of filter replacement and the convenience of operation.

[0024] 2. In this utility model, when unfiltered oil enters the shell, the oil and water are separated by the disturbance plate inside the separator shell. The toothed ring contacts the shell, causing the connecting seat to drive the separator shell to rotate and generate centrifugal force. This achieves the effect of separating oil and water in advance through the separation mechanism, improves the water absorption efficiency of the filter rod, and enhances the practicality of the device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 An embodiment of this utility model provides a water-absorbing filter element for unloading oil tankers, including a shell 1, which serves to fix the internal structure. A filter rod 2 is slidably connected inside the shell 1, and the filter rod 2 serves to absorb water. Both sides of the filter rod 2 are provided with locking holes 3, which serve to lock and fix it. A locking mechanism is provided on the outside of the shell 1 for quick replacement of the filter rod 2. Separation mechanisms are provided at both the upper and lower ends of the filter rod 2 for separating oil and water.

[0033] The locking mechanism includes two mounting shells 4, which serve to fix the internal structure. The opposite sides of the two mounting shells 4 are fixedly connected to the outside of the outer shell 1. Springs 5 ​​are fixedly connected inside the two mounting shells 4. Springs 5 ​​provide elastic force to push the limiting blocks 6. Limiting blocks 6 are fixedly connected to the opposite sides of the two springs 5. Limiting blocks 6 prevent springs 5 ​​from falling off. Pins 7 are fixedly connected inside the two limiting blocks 6. Pins 7 serve to lock and fix the mechanism. Both pins 7 penetrate the outside of the outer shell 1 and lock with the locking holes 3. The top of the mounting shell 4 is fixedly connected to a fixing box 8, which serves to fix the internal structure. Inside the fixing box 8, a sliding plate 9 is slidably connected, which serves to connect to the baffle plate 10. The bottom of the sliding plate 9 is fixedly connected to the baffle plate 10, which serves to prevent the limit block 6 from moving. The bottom of the baffle plate 10 abuts against the top of the limit block 6. The limit block 6 is slidably connected inside the mounting shell 4. A pin 7 passes through both ends of the mounting shell 4. A handle 11 is fixedly connected to the side of the pin 7 away from the limit block 6. A sealing ring 12 is provided on the top of the outer shell 1.

[0034] Reference Figure 1 and Figure 4 The separation mechanism includes two connecting seats 15, which connect to the gear ring 14. The opposite sides of the two connecting seats 15 are fixedly connected to the top and bottom of the filter rod 2, respectively. The gear ring 14 is rotatably connected to the side of the connecting seat 15 away from the filter rod 2. The gear ring 14 serves as a transmission mechanism. The separator housing 13 is rotatably connected to the side of the gear ring 14 away from the connecting seat 15. The separator housing 13 serves to fix the internal structure. Several disturbance plates 16 are provided inside the separator housing 13. The disturbance plates 16 serve to separate oil and water.

[0035] Working principle: The oil inlet pipe and oil outlet pipe are connected to the upper and lower ends of the outer shell 1, respectively. After the oil and water are separated by the separation mechanism, the water is absorbed by the filter rod 2, and the oil is discharged from the oil outlet pipe through the filter rod 2. When the filter rod 2 needs to be replaced, the handle 11 is pulled outward to pull the pin rod 7, which causes the limit block 6 to compress the spring 5 and retract into the mounting shell 4. The baffle plate 10 is automatically lowered by gravity and blocks the limit block 6 so that it cannot move. At this time, the filter rod 2 can be taken out. After replacing the new filter rod 2, the baffle plate 10 is pulled up by the slide plate 9. The spring 5 pushes the limit block 6 and causes the pin rod 7 to re-engage with the locking hole 3 to fix it.

[0036] When unfiltered oil enters the interior of the housing 1, the oil and water are separated by the disturbance plate 16 inside the separator housing 13. The toothed ring 14 contacts the housing 1, causing the connecting seat 15 to drive the separator housing 13 to rotate and generate centrifugal force.
