Description

Technical Field

[0001] This invention relates to the technical field of filtration devices, and more particularly to a metal flexible tube with a visible filtration function. Background Technology

[0002] Power plants have numerous rotating equipment, and the cooling water for this equipment is crucial. The cooling water lowers the temperature of the lubricating oil and bearings. Metal hoses are widely used in the cooling water systems of rotating equipment due to their ability to adapt to complex piping, overcome spatial limitations in cooling water systems, and solve various installation difficulties. The quality of the cooling water is critical to the rotating equipment. If the cooling water is substandard and contains impurities, it will cause blockages in the cooling water pipes, reduce the cooling water flow, and impair the cooling effect on the bearing lubricating oil, posing significant risks to equipment operation. Currently, metal hoses consist of three main components: a corrugated pipe, a braided sleeve, and a connector. The corrugated pipe is the body of the metal hose, providing flexibility; the braided sleeve provides reinforcement and shielding; and the connector provides the connection. As a vital link in the cooling water system of rotating machinery, the metal hose is often connected to a fixed carbon steel pipe via threads. In the event of a cooling water blockage, the metal hose is first removed, and any impurities are replaced or removed from it before reconnecting it to the system to restore the cooling water system.

[0003] During the operation of rotating equipment, if the bearing temperature is too high due to insufficient bearing cooling water, it is necessary to check in time where the cooling water pipe is blocked. However, the existing metal hoses used for circulating cooling water are often closed and need to be disassembled to find the blockage, which greatly affects the efficiency of the staff in cleaning the blockage.

After cleaning the filter cartridge, sliding the filter cartridge allows it to be embedded in the branched pipeline. When the filter cartridge comes into contact with the obstructing fluid, the obstructing fluid moves, so that the water flow is no longer blocked. Attached Figure Description

[0028] Example 1

[0029] Reference Figure 1 A schematic diagram of the overall structure of a metal flexible tube with a visual filtration function is provided, as shown below. Figure 1-3A flexible metal hose with a visible filtration function includes a visible filtration assembly 100, comprising an outer pipe component 101 and a detachable filter component 102 located within the outer pipe component 101; and a flexible metal hose body 200 interconnected with the outer pipe component 101 via a flange; wherein the outer pipe component 101 includes a main pipe 101a, a branch pipe 101b connected to the lower side of the main pipe 101a, and a movable cover provided at the end of the branch pipe 101b; the detachable filter component 102 includes a filter cylinder 102a, and a flow-blocking baffle 102b is provided on one side of the filter cylinder 102a; the filter cylinder 102a is slidably embedded inside the branch pipe 101b, and the flow-blocking baffle 102b is limitedly embedded inside the main pipe 101a; both the branch pipe 101b and the filter cylinder 102a are made of transparent material.

[0030] Cooling water flows into the main pipe 101a through the metal hose body 200. After passing through the obstruction fluid 102b, the cooling water enters the filter cartridge 102a. The cooling water filtered by the filter cartridge 102a then re-enters the main pipe 101a for continued use. Through the branch pipe 101b and the filter cartridge 102a, the blockages remaining in the filter cartridge 102a can be seen. When there is too much blockage, the filter cartridge 102a is removed. At this time, the obstruction fluid 102b moves, causing the filter cartridge 102a to be obstructed, preventing the cooling water from continuing to flow. After cleaning the filter cartridge 102a, sliding the filter cartridge 102a allows it to be embedded in the branch pipe 101b. When the filter cartridge 102a comes into contact with the obstruction fluid 102b, the obstruction fluid 102b moves, so that the water flow is no longer blocked.

[0031] Furthermore, the filter cartridge 102a includes a filter cartridge body 102a-1, and a leak-proof cover 102a-2 is threadedly connected to the lower end of the filter cartridge body 102a-1; the top end of the filter cartridge body 102a-1 is embedded inside the main pipe 101a, and all the water flow at the inlet of the main pipe 101a is directed into the interior of the filter cartridge body 102a-1.

[0032] The leak-proof cover 102a-2 can prevent impurities in the cooling water from leaking out, and the filter cartridge body 102a-1 is slidably connected to the inside of the branch pipe 101b.

[0033] Furthermore, the filter cartridge body 102a-1 includes a cylinder body 102a-1a, and a plurality of filter holes 102a-1b are provided on one side of the cylinder body 102a-1a; the filter holes 102a-1b are connected to the outlet of the main pipe 101a.

[0034] Several filter holes 102a-1b are evenly distributed on the cylinder body 102a-1a, and impurities can be blocked from passing through the filter holes 102a-1b.

[0035] Operation process: Cooling water flows into the main pipe 101a through the metal hose body 200. After passing through the flow-blocking 102b, the cooling water enters the cylinder 102a-1a. Impurities in the cooling water are blocked. After being filtered, the cooling water continues to be used after passing through the filter holes 102a-1b. The leak-proof cover 102a-2 can prevent impurities in the cooling water from leaking out, thus facilitating subsequent cleaning.

[0036] Example 2

[0037] Reference Figure 1-5 The difference between this embodiment and the first embodiment is that the flow-blocking block 102b includes a first flow-blocking block 102b-1 and a second flow-blocking block 102b-2, both of which are embedded inside the main pipeline 101a.

[0038] The first flow-blocking block 102b-1 and the second flow-blocking block 102b-2 can block or allow the cooling water flowing through the main pipe 101a to pass through.

[0039] Furthermore, the first flow-blocking block 102b-1 includes a first flow-blocking block body 102b-1a, and a plurality of first through holes 102b-1b are uniformly formed inside the first flow-blocking block body 102b-1a; the second flow-blocking block 102b-2 includes a second flow-blocking block body 102b-2a, and a plurality of second through holes 102b-2b are uniformly formed inside the second flow-blocking block body 102b-2a; rotating the second flow-blocking block body 102b-2a can make the second through holes 102b-2b and the first through holes 102b-1b interconnected.

[0040] The number of the second through hole 102b-2b and the number of the first through hole 102b-1b are corresponding, and the second through hole 102b-2b and the first through hole 102b-1b can be completely disconnected.

[0041] Furthermore, a first positioning ring 102b-1c is provided at one end of the outer side of the first flow blocking block body 102b-1a; a second positioning ring 102b-2c is provided at one end of the outer side of the second flow blocking block body 102b-2a; the first positioning ring 102b-1c and the second positioning ring 102b-2c are adjacent to each other and are fitted into the groove provided inside the main pipe 101a.

[0042] The first positioning ring 102b-1c is fixed to the outside of the first flow-blocking block body 102b-1a, the first flow-blocking block body 102b-1a is fixed to the inside of the main pipe 101a, and the second positioning ring 102b-2c is fixed to the outside of the second flow-blocking block body 102b-2a. The first positioning ring 102b-1c and the second positioning ring 102b-2c are the same size. The first positioning ring 102b-1c and the second positioning ring 102b-2c can confine the first flow-blocking block body 102b-1a and the second flow-blocking block body 102b-2a to the inside of the main pipe 101a.

[0043] Furthermore, a first oblique locking tooth 102b-2d is provided on one side of the second flow-blocking block body 102b-2a; a second oblique locking tooth 102a-1c is provided at the upper end of the cylinder body 102a-1a; the first oblique locking tooth 102b-2d can be combined with the second oblique locking tooth 102a-1c to form a sealed cylinder.

[0044] The first oblique locking tooth 102b-2d is fixed on the second flow-blocking block body 102b-2a, and the second oblique locking tooth 102a-1c is fixed on the upper end of the cylinder body 102a-1a.

[0045] Furthermore, a transmission shaft 102b-2e is provided at the middle position on one side of the second flow blocking block body 102b-2a, and the transmission shaft 102b-2e is fixed inside the first flow blocking block body 102b-1a by bearings.

[0046] The transmission shaft 102b-2e is fixed at the middle position on one side of the second flow blocking block body 102b-2a, and the transmission shaft 102b-2e rotates stably through the bearing.

[0047] Furthermore, a torsion spring 102b-2g is provided on the outer side of the drive shaft 102b-2e; an inner cavity is also provided in the first flow-blocking block 102b-1 to accommodate the movement of the drive shaft 102b-2e; one end of the torsion spring 102b-2g is embedded in the second flow-blocking block body 102b-2a, and the other end of the torsion spring 102b-2g is embedded in the first flow-blocking block body 102b-1a;

[0048] The second flow-blocking block body 102b-2a can be rotated and reset by the torsion spring 102b-2g.

[0049] The rest of the structure is the same as in Example 1.

[0050] Operation process: When the filter cartridge 102a is removed, the second oblique tooth 102a-1c no longer abuts against the first oblique tooth 102b-2d. At this time, the torsion spring 102b-2g restores its deformation, causing the second flow-blocking block body 102b-2a to rotate. The rotation of the second flow-blocking block body 102b-2a causes the second through hole 102b-2b and the first through hole 102b-1b to no longer be connected, and the cooling water is blocked and thus no longer flows.

[0051] After cleaning the filter cartridge 102a, slide the filter cartridge 102a into the branch pipe 101b. The movement of the second oblique tooth 102a-1c causes the first oblique tooth 102b-2d to drive the second flow-blocking block body 102b-2a to rotate. The rotation of the second flow-blocking block body 102b-2a causes the second through hole 102b-2b and the first through hole 102b-1b to reconnect, so that the cooling water can flow again.

[0052] Example 3

[0053] Reference Figure 1-5 This embodiment differs from the above embodiments in that: after the transmission shaft rod 102b-2e passes through the first flow-blocking block body 102b-1a, it is also provided with a scraping strip 102b-2h; the scraping strip 102b-2h can scrape the first through hole 102b-1b;

[0054] Among them, the scraping strip 102b-2h and the drive shaft 102b-2e are fixedly connected.

[0055] The rest of the structure is the same as in Example 2.

[0056] Operation process: When the second flow-blocking block body 102b-2a rotates, the second flow-blocking block body 102b-2a drives the transmission shaft 102b-2e to rotate. The rotation of the transmission shaft 102b-2e drives the scraper 102b-2h to rotate. The rotation of the scraper 102b-2h causes the surface of the first flow-blocking block body 102b-1a to be scraped, thereby preventing impurities from adhering and blocking the flow of cooling water.

[0058] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.
