Description

Technical Field

[0001] The invention relates to the technical field of filter cleaning devices, and in particular to an offshore filter cleaning device. Background Art

[0002] Offshore oil and gas production facilities are mainly responsible for the production and export of oil and gas. Generally speaking, offshore oil and gas are transported by pipeline. When the oil and gas pipeline transmission distance is long or there are some special pressure requirements, an export pump or compressor is required to increase the oil and gas transmission pressure. Since oil and gas exist underground, during the oil and gas extraction process, underground fine sand and gravel will inevitably be sucked up along with the oil and gas.

[0003] Fine sand and gravel will move along with oil and gas in the surface pipeline. When it reaches the external pump, since the external pump is a multi-stage centrifugal pump, the precision matching degree inside the pump is relatively high. If fine sand and gravel are allowed to enter the external pump, it will cause irreparable damage to the internal structure of the pump. Therefore, a basket filter is generally installed at the inlet of the external pump. The basket filter can effectively filter the sand and gravel. As the use time of the basket filter increases, some filtered impurities will inevitably accumulate inside it. At this time, the basket filter needs to be opened to clean its inside.

[0004] The traditional cleaning method is to manually clean the inner wall of the basket filter with a water gun. For some impurities that are difficult to remove, they are manually removed with a flat shovel. This traditional cleaning method has the following problems in actual operation:

[0005] 1. Only one position is cleaned each time, resulting in low cleaning efficiency and poor cleaning effect. Since the external transfer pump is a key equipment on the offshore platform, the traditional cleaning method is time-consuming and not conducive to safe production;

[0006] 2. When using a flat shovel to remove impurities, people need to put their hands into the filter, which may easily cause hand injuries.

[0007] Therefore, an offshore filter cleaning device is urgently needed to solve the above technical problems. Summary of the invention

[0008] The purpose of the present invention is to provide an offshore filter cleaning device, which can effectively simplify the cleaning process, save cleaning costs, improve cleaning efficiency, shorten cleaning time, effectively shorten the shutdown time of the external pump caused by cleaning the filter, and can comprehensively clean the inside of the platform basket filter, avoiding the problem of poor cleaning effect caused by traditional cleaning methods, making the basket filter safer and more reliable during use.

Compared with ordinary bearings, the bearing with a sealing structure can effectively prevent the problem of water leakage from the bearing of the liquid inlet section when water pressure accumulates in the main body 1, so as to improve the safety and reliability during use.

[0051] Figure 3 is a schematic diagram of the structure of this embodiment when in use (the baffle is not shown), Figure 4 yes Figure 3 The schematic diagram of the half-section structure is as follows: 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 the nozzle assembly 31 and the cleaning assembly 32 are staggered along the axial direction of the main body 1.

The nozzle 312 is detachably connected to the other end of the nozzle connecting rod 311.

[0054] In order to improve the stability and practicality of the overall structural connection, the nozzle connecting rod 311 is welded to the main body 1 in this embodiment. In order to facilitate use and improve the cleaning effect, the nozzle 312 is detachably connected to the nozzle connecting rod 311 so that the nozzle 312 can be replaced according to the use needs.

[0055] Specifically, in this embodiment, the outer surface of the end of the nozzle connecting rod 311 is provided with an external thread, and the inside of the nozzle 312 is provided with an internal thread.

In this embodiment, two groups of connection assemblies 42 are provided, and the two groups of connection assemblies 42 are symmetrically arranged on both sides of the main body 1, which can make the connection more stable and safer and more reliable during use.

[0063] The two ends of the screw rod 421 are respectively located on both sides of the connecting plate 41 , and the screw rod 421 can slide in the slideway 410 ; the nut 422 is connected to the screw rod 421 , and the nut 422 includes at least two nuts 422 , which are distributed on both sides of the connecting plate 41 .

[0064] By using the nut 422 and the screw 421 in cooperation, the screw 421 can slide in the slideway 410, so as to conveniently connect the screw 421 with the screw hole of the filter 5, thereby keeping the marine filter cleaning device and the filter relatively fixed for easy cleaning operation.

[0065] The conventional method of flushing with water easily causes water to splash outside the basket filter, causing deck pollution. In this regard, the marine filter cleaning device in this embodiment further 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 personal injury caused by liquid splashing during cleaning.

[0066] Specifically, in this embodiment, in order to facilitate production and assembly, the baffle 6 is provided to include two left and right pieces. Both baffles are semicircular structures, and an arc-shaped connecting ear protruding from the baffle 6 is provided on the side close to the diameter of the semicircular structure. When in use, the two baffles 6 are combined into a circle and then fixedly connected to the main body 1 by means of screws passing through the holes provided on the connecting ears.

[0067] As an optional embodiment, the offshore filter cleaning device further comprises a main bearing 7 and a shaft seal gland 8. The main bearing 7 is arranged between the main body 1 and the connecting mechanism 4; the shaft seal gland 8 is arranged above the main bearing 7 to prevent sealing lubricating oil.

[0068] In this embodiment, Figure 6 Schematic diagram of the top view of the structure of this embodiment, as shown in Figure 6 As shown, the marine filter cleaning device further comprises a hand wheel 9, which is connected to the main body 1. The hand wheel 9 can drive the main body 1 to rotate, so as to realize manual rotation of the cleaning device.

[0069] By arranging the main bearing 7 and the hand wheel 9, the cleaning height and the cleaning angle can be adjusted as required, so that all-round cleaning of the inner wall of the filter can be achieved.

[0070] When in use, this marine filter cleaning device can greatly improve the cleaning efficiency and save cleaning costs. Its working process is: fresh water enters from the liquid 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 then sprays out to clean the inside of the filter 5; the cleaning plate 321 is fitted with the inner wall of the filter 5 through the pressure given by the connecting rod 322 with adjustable length, and then the cleaning device is rotated by the force of the hand wheel 9, thereby cleaning the inner wall of the filter, removing impurities, and achieving an efficient cleaning effect of the filter 5.

[0071] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
