Description

Technical Field

[0001] This utility model relates to the technical field of filter cleaning devices, and in particular to a marine filter cleaning device. Background Technology

[0002] Offshore oil and gas production facilities primarily produce and transport oil and gas. Generally, offshore oil and gas are transported via pipelines. When the pipeline distance is long or there are special pressure requirements, external pumps or compressors are needed to increase the pressure of the oil and gas transmission. Since oil and gas exist underground, fine sand and gravel from the ground inevitably get sucked up along with the oil and gas during the extraction process.

[0003] Fine sand and gravel can travel with oil and gas through surface pipelines. When they reach the external transfer pump, which is a multi-stage centrifugal pump requiring precise internal fitting, allowing fine sand and gravel to enter can cause irreparable damage to its internal structure. Therefore, a basket filter is typically installed at the pump inlet. This basket filter effectively filters sand and gravel. However, over time, some filtered impurities inevitably accumulate inside the basket filter, requiring it to be opened and cleaned.

[0004] The traditional cleaning method involves manually cleaning the inner wall of the basket filter with a water gun. For some stubborn impurities, a flat spatula is then used to remove them manually. This traditional cleaning method has the following problems in actual operation:

[0005] 1. Cleaning only one area at a time results in low cleaning efficiency and poor cleaning effect. Since the external pump is a key piece of equipment on the offshore platform, the traditional cleaning method is time-consuming and not conducive to safe production.

[0006] 2. When using a flat spatula to remove impurities, personnel need to put their hands inside the filter, which can easily cause hand injuries.

[0007] Therefore, there is an urgent need for a marine filter cleaning device to solve the above-mentioned technical problems. Utility Model Content

[0045] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0046] In the description of this utility model, it should be understood that the terms "center", "side", "length", "width", "height", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "side", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0047] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] Figure 1 This is a structural schematic diagram of this embodiment. Figure 2 yes Figure 1 A cross-sectional structural diagram, such as Figure 1 and Figure 2 As shown in the figure, this embodiment provides a marine filter cleaning device, including a main body 1, a liquid inlet mechanism 2, a cleaning mechanism 3, and a connecting mechanism 4.

[0049] The main body 1 has a liquid flow channel 10 inside; the liquid inlet mechanism 2 includes a liquid inlet valve 21, which is located in the liquid inlet section of the main body 1 and is used to control the flow rate and switch of the liquid entering the liquid flow channel 10. In this embodiment, the liquid inlet valve 21 includes a water inlet switch ball valve, which can control and adjust the water inlet volume and flushing pressure as needed to meet the cleaning needs under different working conditions.

[0050] Specifically, such as Figure 2 As shown, the liquid inlet mechanism 2 in this embodiment also includes a sealed bearing 22, and the liquid inlet valve 21 is connected to the liquid inlet section of the main body 1 through the sealed bearing 22. The sealed bearing 22 is fixed to the main body 1 by compression. By setting the sealed bearing 22, the safety issues caused by twisting in the liquid inlet section can be avoided when the main body 1 rotates. In this embodiment, the sealed bearing 22 includes a bearing and a sealing structure, specifically a sealing ring. Compared with ordinary bearings, using a bearing with a sealing structure effectively prevents water leakage from the bearing in the liquid inlet section when water pressure accumulates in the main body 1, thereby improving safety and reliability during use.

[0051] Figure 3 This is a schematic diagram of the structure during use in this embodiment (baffle not shown). Figure 4 yes Figure 3 A schematic diagram of the half-section structure, as shown below. Figure 3 and Figure 4As shown, the cleaning mechanism 3 includes a nozzle assembly 31 and a cleaning assembly 32. The nozzle assembly 31 is connected to the liquid flow channel 10. The nozzle assembly 31 and the cleaning assembly 32 are arranged at intervals along the circumference of the main body 1, and are staggered along the axial direction of the main body 1. This arrangement allows for the cleaning of different types of dirt on the inner wall of the filter by the nozzle assembly 31 and the cleaning assembly 32. The staggered arrangement of the nozzle assembly 31 and the cleaning assembly 32 enables comprehensive cleaning of the filter's interior, resulting in high cleaning efficiency and effectively shortening the shutdown time of the external pump caused by filter cleaning, making the filter safer and more reliable during use.

[0052] like Figures 1-4 As shown, the connecting mechanism 4 includes a connecting plate 41 and a connecting component 42. The connecting plate 41 is connected to the main body 1, and a slide rail 410 is provided on the connecting plate 41. The connecting component 42 can slide within the slide rail 410 and is used to connect the connecting plate 41 and the filter 5. By providing the slide rail 410 on the connecting plate 41, this marine filter cleaning device can be adjusted and installed according to different filter sizes, making the connecting mechanism 4 adaptable to filters of different specifications. In use, the marine filter cleaning device and the filter are fixed relative to each other through the connecting mechanism 4 to facilitate efficient and stable cleaning and improve the cleaning effect.

[0053] As an optional implementation method, such as Figures 1-4 As shown, the nozzle assembly 31 includes a nozzle connecting rod 311 and a nozzle 312. The nozzle connecting rod 311 has a hollow interior, one end of which is connected to the main body 1 and communicates with the liquid flow channel 10. The nozzle 312 is detachably connected to the other end of the nozzle connecting rod 311.

[0054] To improve the stability and practicality of the overall structural connection, in this embodiment, the nozzle connecting rod 311 is welded to the main body 1. For ease of use and to improve the cleaning effect, the nozzle 312 is detachably connected to the nozzle connecting rod 311, allowing the nozzle 312 to be replaced as needed.

[0055] Specifically, in this embodiment, the outer surface of the nozzle connecting rod 311 is provided with an external thread, and the nozzle 312 is provided with an internal thread. The nozzle connecting rod 311 and the nozzle 312 are connected by the internal and external threads.

[0056] Alternatively, the nozzle 312 can be a shower nozzle for initial cleaning of impurities, or it can be a jet nozzle for cleaning stubborn impurities.

[0057] In some embodiments, the nozzle 312 can be configured with two interchangeable types, allowing the water flow pattern to be adjusted by changing the nozzle head, thereby improving the cleaning efficiency of the inner wall. For example, after initially using a shower-type nozzle to clean impurities, a jet-type nozzle can be used to further clean stubborn impurities, thereby improving the cleaning effect.

[0058] As an optional implementation method, Figure 5 This is a schematic diagram of the left-side structure of this embodiment (connecting mechanism not shown), as follows: Figure 5 As shown, the cleaning assembly 32 includes a cleaning plate 321 and a connecting rod 322. The outer surface of the cleaning plate 321 is provided with a cleaning layer, which is used to contact the inner wall of the filter 5 to remove impurities. The connecting rod 322 is a telescopic rod to accommodate cleaning the inner walls of filters with different inner diameters. Both ends of the connecting rod 322 are connected to the cleaning plate 321 and the main body 1, respectively.

[0059] In this embodiment, the cleaning plate 321 is welded to the connecting rod 322. The cleaning plate 321 adopts an arc-shaped structure to adapt to the inner surface of the filter.

[0060] Optionally, the cleaning layer in this embodiment includes sandpaper, which is replaceably disposed on the outer surface of the cleaning plate 321 for removing impurities.

[0061] For basket filters of different sizes, the water guns commonly used on platforms cannot clean smaller basket filters. To address this, in some embodiments, a spring structure is incorporated within the connecting rod 322. This spring structure can extend or shorten as needed and applies pressure to the inner wall of the cleaning plate 321 and the filter 5. This allows the cleaning assembly 32 of this marine filter cleaning device to be used with various types and sizes of filters 5, achieving good cleaning results for each type.

[0062] As an optional implementation, the connecting assembly 42 includes a screw 421 and a nut 422. In this embodiment, two sets of connecting assemblies 42 are provided, and the two sets of connecting assemblies 42 are symmetrically arranged on both sides of the main body 1, which can make the connection more stable and the use safer and more reliable.

[0063] The two ends of the screw 421 are located on both sides of the connecting plate 41, and the screw 421 can slide within the slide rail 410; the nut 422 is connected to the screw 421, and there are at least two nuts 422 distributed on both sides of the connecting plate 41.

[0064] With the cooperation of nut 422 and screw 421, screw 421 can slide in slide rail 410, which facilitates the connection of screw 421 with screw hole of filter 5, thereby keeping the marine filter cleaning device and filter relatively fixed for cleaning operation.

[0065] Traditional water rinsing methods can easily splash water outside the basket filter, causing deck contamination. Therefore, the marine filter cleaning device in this embodiment also includes a baffle 6, such as... Figure 1 As shown, the baffle 6 is connected to the main body 1 and is located between the liquid inlet mechanism 2 and the cleaning mechanism 3. The baffle 6 is used to prevent deck contamination and personnel injury caused by liquid splashing during cleaning.

[0066] Specifically, in this embodiment, for ease of production and assembly, the baffle 6 is provided as two pieces, left and right, both of which are semi-circular structures. An arc-shaped connecting ear protrudes from the baffle 6 on the side of the semi-circular structure closest to the diameter. In use, the two baffles 6 are combined into a circle and then fixed to the main body 1 by passing a screw through the hole provided on the connecting ear.

[0067] As an optional implementation, the marine filter cleaning device also includes a main bearing 7 and a shaft seal cover 8. The main bearing 7 is disposed between the main body 1 and the connecting mechanism 4; the shaft seal cover 8 is disposed above the main bearing 7 to prevent sealing lubricating oil.

[0068] In this embodiment, Figure 6 This is a top view of the structure of this embodiment, as shown below. Figure 6 As shown, the marine filter cleaning device also includes a handwheel 9, which is connected to the main body 1. The handwheel 9 can drive the main body 1 to rotate, so as to realize the manual rotation of the cleaning device.

[0069] By setting the main bearing 7 and handwheel 9, the cleaning height and cleaning angle can be adjusted as needed to achieve all-round cleaning of the filter inner wall.

[0070] This marine filter cleaning device can greatly improve cleaning efficiency and save cleaning costs when in use. Its working process is as follows: Fresh water enters from the inlet valve 21, then passes through the liquid flow channel 10 inside the main body 1, reaches the nozzle connecting rod 311, passes through the nozzle 312, and is then sprayed out to clean the inside of the filter 5; the cleaning plate 321 is pressed against the inner wall of the filter 5 by the pressure given by the adjustable length connecting rod 322, and then the cleaning device is rotated by the force of the handwheel 9, thereby cleaning the inner wall of the filter, removing impurities, and achieving a highly efficient cleaning effect for the filter 5.

[0071] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
