Description

Technical Field

[0001] The invention relates to the technical field of flash tank cleaning, in particular to a high-pressure flash tank continuous flushing device with a safety protection function. Background Art

[0002] At present, in the aerospace furnace gasification process ash water treatment system, high-pressure flash tanks are mostly used for treatment. The black water discharged from the gasifier, washing tower and cyclone separation tank is sent to the high-pressure flash tank for flash evaporation to recover the heat in the ash water. However, due to the high solid content of the black water discharged from the gasifier, washing tower and cyclone separation tank, and the poor fluidity of the cone of the high-pressure flash tank, ash accumulates in the high-pressure flash tank and blocks the pipeline. Long-term ash accumulation leads to a reduction in the space of the high-pressure flash tank, affecting heat recovery and reducing the role of the high-pressure flash tank. Therefore, the staff will clean the high-pressure flash tank after using it for a period of time. The current high-pressure flash tank cleaning process is The traditional method relies on workers to use handheld water guns to directly spray cleaning liquid to flush the inner wall of the tank. However, this method faces many challenges. First, due to the relatively narrow design of the tank opening, it is extremely inconvenient to operate the water gun for thorough flushing, especially for dirt far away from the tank opening and in the corners of the tank. In addition, for those stubborn residues that are difficult to remove by water flushing alone, different types of cleaning tools need to be manually replaced for secondary operations. This process is not only time-consuming and lengthy, but also consumes a lot of physical strength, which greatly reduces the cleaning efficiency and work comfort. For this reason, we propose a high-pressure flash tank continuous flushing device with safety protection function. Summary of the invention

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1-Figure 9 and Fig.11 The present invention provides a technical solution: a high-pressure flash tank continuous flushing device with a safety protection function, comprising a supporting plate 1, a mounting rod 2 and a nozzle 3, the nozzle 3 being connected to an external water supply device through a conduit, which is a prior art, the supporting plate 1 and the mounting rod 2 being rotatably connected, and also comprising a cleaning plate 4, the cleaning plate 4 being arranged on the mounting rod 2, and the cleaning plate 4 being arranged in plurality, and the cleaning plate 4 being extended into the flash tank to clean the inner wall of the tank body.

[0019] The cleaning deployment component 5 is arranged on the mounting rod 2, and the cleaning plate 4 is arranged on the cleaning deployment component 5. The cleaning deployment component 5 is used to control the cleaning plate 4 extending into the flash tank to be deployed to clean the inner wall of the tank.

[0020] The advantage of the setting of the cleaning deployment component 5 is that the cleaning plate 4 can be recovered into the mounting rod 2 so that it can pass through the flash tank opening into the flash tank to flush the inner wall of the tank. This design allows the flushing device to adapt to flash tanks of different sizes and shapes, especially those with narrow openings. By folding or contracting the cleaning plate 4, the device can easily enter and adapt to the space inside the tank, thereby improving its flexibility and versatility in use. For areas inside the tank that are difficult to reach with traditional flushing methods, the accessibility of flushing can be significantly improved. Not only that, the cleaning plate 4 can penetrate deep into the tank to effectively flush every corner and difficult-to-clean area, ensuring thorough cleaning of the inner wall of the tank. At the same time, when the flushing device needs to be transported to the site or moved between different tanks, it helps to save space. By recovering the cleaning plate 4 into the mounting rod 2, the size and occupied space of the device can be reduced, making it easier to transport and store.

[0021] The stripping assembly 10 is arranged on the cleaning plate 4 and is used to clean the stubborn residues in the flash tank which are difficult to be stripped by water washing.

[0022] The advantage of the stripping assembly 10 is that, in the process of cleaning the flash tank, when encountering attachments that cannot be washed off, the attachments can be scraped off by controlling the scraper 114 to flip, and when there are no attachments, the scraper 114 will switch to the cleaning roller 113. This design combines the two cleaning methods of flushing and scraping, and can more effectively remove the stubborn attachments on the inner wall of the tank body. When flushing cannot completely remove the attachments, the scraper 114 can play a key role in removing the attachments from the surface of the tank body by physical scraping, ensuring the thoroughness of the cleaning. At the same time, when there are no attachments, the scraper can remove the attachments from the surface of the tank body by physical scraping. The scraper 114 will automatically switch to the cleaning roller 113. The cleaning roller 113 is usually made of soft and wear-resistant materials, such as nylon, and can gently clean without damaging the inner wall of the tank. This design avoids damage to the inner wall of the tank due to excessive scraping and extends the service life of the tank. Moreover, by automatically switching the scraper 114 and the cleaning roller 113, this design avoids unnecessary repeated flushing and scraping operations, thereby saving time and water resources. At the same time, due to the gentle cleaning method of the cleaning roller 113, energy consumption and cost increase caused by excessive cleaning are also reduced.

[0023] The cleaning deployment component 5 includes a cleaning part 6 arranged on the mounting rod 2, and the cleaning part 6 is used to control the nozzle 3 to flush the inner wall of the flash tank. The mounting rod 2 is provided with a deployment part 7, and the deployment of the cleaning plate 4 is controlled by the deployment part 7. The mounting rod 2 is provided with a driving part 8, and the driving part 8 is used to provide power for the deployment part 7. The deployment part 7 is provided with an extension part 9, and the extension part 9 is used to adjust the distance between the cleaning plate 4 and the mounting rod 2 to adapt to flash tanks of different sizes.

[0024] The cleaning member 6 includes a through slot 61 provided on the mounting rod 2, a plurality of recovery slots 62 being provided in the through slot 61, a rotating shaft 1 63 being rotatably provided in the recovery slot 62, a rotating rod 64 being provided on the rotating shaft 1 63, an extension slot 65 being provided on the rotating rod 64, an extension rod 66 being slidably provided in the extension slot 65, a rotating shaft 2 67 being rotatably provided on the extension rod 66, a rotating seat 68 being provided on the rotating shaft 2 67, the rotating seat 68 being connected to the cleaning plate 4, and the cleaning plate 4 being connected to the nozzle 3.

[0025] The advantage of the cleaning part 6 is that by folding or contracting the cleaning plate 4, it can easily enter and adapt to the space inside the tank, thereby improving its flexibility and versatility in use. At the same time, it helps to save space when the flushing device needs to be transported to the site or moved between different tanks. By retracting the cleaning plate 4 into the mounting rod 2, the size and occupied space of the device can be reduced, making it easier to transport and store.

[0026] The unfolding member 7 includes a positioning shaft 71 arranged in the recovery groove 62, a pushing gear 72 is arranged on the positioning shaft 71, a fixing plate 1 73 is arranged on the rotating rod 64, a fixing rod 74 is rotatably arranged on the fixing plate 1 73, an unfolding gear 1 75 meshing with the pushing gear 72 is arranged on the fixing rod 74, a fixing plate 2 76 is arranged on the extension rod 66, a sliding rod 77 is rotatably arranged on the fixing plate 2 76, the sliding rod 77 is slidably connected to the fixing rod 74, an unfolding gear 2 78 is arranged on the sliding rod 77, and a deflection gear 79 meshing with the unfolding gear 2 78 is arranged on the rotating shaft 2 67.

[0027] The advantage of the deployment of the unfolding member 7 is that by folding or contracting the cleaning plate 4, it can easily enter the space inside the tank body, thereby improving its flexibility and versatility of use. For the internal areas of the tank body that are difficult to reach with traditional flushing methods, the accessibility of flushing can be significantly improved. Not only that, the cleaning plate 4 can penetrate deep into the tank body to effectively flush every corner and hard-to-clean area to ensure thorough cleaning of the inner wall of the tank body. Moreover, since the cleaning plate 4 can fit tightly against the inner wall of the tank body and provide a uniform and powerful flushing water flow, this design helps to improve the cleaning efficiency and effect, and the nozzle 3 on the cleaning plate 4 can ensure that every corner of the inner wall of the tank body is fully flushed.

[0028] The driving member 8 includes a control knob 81 rotatably set on the mounting rod 2, a driving rod 82 is set on the control knob 81, the driving rod 82 extends into the through slot 61, a guide plate 83 is set on the driving rod 82, the guide plate 83 is slidably connected to the through slot 61, the control knob 81 is threadedly connected to the driving rod 82, a lifting plate 84 is set on the driving rod 82, a driving rack 85 is set on the lifting plate 84, and a driving gear 86 engaged with the driving rack 85 is set on the rotating shaft 63.

[0029] The extension member 9 includes a sliding groove 91 opened on the extension groove 65, a moving block 92 is provided on the extension rod 66, and the moving block 92 is slidably connected to the sliding groove 91, a return spring 93 is provided in the extension groove 65, and one end of the return spring 93 is connected to the extension rod 66, a guide block 94 is provided on the rotating rod 64, a power groove 95 is opened in the driving rod 82, a power block 96 is rotatably provided on the driving rod 82, a pull rod 97 is provided on the power block 96, the pull rod 97 is threadedly connected to the power block 96, and the pull rod 97 extends into the power groove 95, a limit plate 99 is provided on the pull rod 97, and the limit plate 99 is slidably connected to the power groove 95, a traction rope 98 is provided on the moving block 92, the traction rope 98 passes through the guide block 94 and the driving rod 82 and is connected to the pull rod 97, and the traction rope 98 is movably connected to the guide block 94 and the driving rod 82.

[0030] The advantage of setting the extension piece 9 is that the distance between the nozzle 3 on the cleaning plate 4 and the inner wall of the tank body can be adjusted. By adjusting the distance between the nozzle 3 and the inner wall of the tank body, it can be ensured that the water flow or cleaning liquid can evenly and fully cover the inner wall of the tank body, thereby improving the cleaning effect.

[0031] When cleaning the flash tank, first, the unfolded mounting rod 2 is inserted into the flash tank through the opening of the flash tank, and then the control knob 81 is turned. The control knob 81 rotates to drive the driving rod 82 threadedly connected thereto to rise, and the rising of the driving rod 82 drives the lifting plate 84 to rise. The rising of the lifting plate 84 drives the driving rack 85 disposed thereon to rise. The rising of the driving rack 85 drives the driving gear 86 engaged with it to rotate. The rotation of the driving gear 86 drives the rotating shaft 63 to rotate. The rotation of the rotating shaft 63 drives the rotating rod 64 to deflect. The deflection of the rotating rod 64 drives the extension rod 66 and the cleaning plate 4 located on the extension rod 66 to deflect.

[0032] When the rotating rod 64 deflects, it drives the unfolding gear 75 located thereon to deflect. During the deflection process, the unfolding gear 75 rotates under the push of the pushing gear 72. The rotation of the unfolding gear 75 drives the fixed rod 74 to rotate. The rotation of the fixed rod 74 drives the sliding rod 77 to rotate synchronously. The rotation of the sliding rod 77 drives the unfolding gear 75 arranged thereon to rotate. The rotation of the unfolding gear 75 drives the deflection gear 79 arranged on the rotating shaft 2 67 and meshed with it to rotate, thereby driving the cleaning plate 4 to unfold and be parallel to the inner wall of the tank body.

[0033] When it is necessary to adjust the distance between the cleaning plate 4 and the inner wall of the tank body, first rotate the power block 96. The rotation of the power block 96 drives the pull rod 97 threadedly connected to it to rise. The rising of the pull rod 97 drives the traction rope 98 connected to it to rise. Because the traction rope 98 passes through the guide block 94 and the driving rod 82 and is connected to the pull rod 97, when one end of the traction rope 98 is pulled, under the limit of the guide block 94, the moving block 92 connected to the traction rope 98 will move to a position opposite to the pulling direction of the traction rope 98, thereby driving the extension rod 66 to extend from the extension groove 65, so that the distance between the cleaning plate 4 and the inner wall of the tank body is changed, and at this time the reset spring 93 is in a stretched state.

[0034] The stripping assembly 10 includes a separator 11 disposed on a cleaning plate 4 , which is used to clean the attachments on the inner wall of the tank body. An adjustment control 12 is disposed on the cleaning plate 4 , which is used to adjust the cleaning method of the separator 11 .

[0035] The separator 11 includes a mounting groove 111 provided on the cleaning plate 4 , a switching rod 112 is rotatably provided in the mounting groove 111 , a cleaning roller 113 and a scraper 114 are respectively provided on both sides of the switching rod 112 , and the cleaning roller 113 is made of nylon.

[0036] The advantage of setting up the separation piece 11 is that during the process of cleaning the flash tank, when encountering attachments that cannot be washed off, the attachments can be scraped off by controlling the scraper 114 to flip, and when there are no attachments, the scraper 114 will switch to the cleaning roller 113. This design combines the two cleaning methods of flushing and scraping, and can more effectively remove stubborn attachments on the inner wall of the tank body. At the same time, when there are no attachments, the scraper 114 will automatically switch to the cleaning roller 113. The cleaning roller 113 is usually made of soft and wear-resistant materials, such as nylon, and can gently clean without damaging the inner wall of the tank body. This design avoids damage to the inner wall of the tank body caused by excessive scraping.

[0037] The adjustment control unit 12 includes a trigger rod 121 rotatably arranged in the installation groove 111, the trigger rod 121 is connected to the installation groove 111 through a torsion spring, a trigger plate 122 is arranged on the trigger rod 121, an adjustment groove 123 is opened on the cleaning plate 4, one end of the switching rod 112 and the trigger rod 121 are both extended into the adjustment groove 123, and one end of the switching rod 112 and the trigger rod 121 located in the adjustment groove 123 is provided with a toothed belt wheel 124, and a toothed belt wheel 124 is provided with a toothed belt 125.

[0038] When the operator encounters a situation where attachments on the inner wall of the tank need to be cleaned during the process of rotating the mounting rod 2 to clean the inner wall of the tank, the cleaning plate 4 is first controlled to be close to the inner wall of the tank, and then the cleaning plate 4 is rotated. When the trigger plate 122 on the cleaning plate 4 contacts the solid attachments, the trigger plate 122 is pushed to deflect. When the trigger plate 122 deflects, the trigger rod 121 is driven to deflect synchronously. The deflection of the trigger rod 121 drives the switching rod 112 to rotate through the toothed belt wheel 124 and the toothed belt 125, so that the scraper 114 set on the switching rod 112 extends out to scrape off the solid attachments. At the same time, when the attachments are scraped off, the trigger plate 122 is no longer hindered, thereby driving the trigger rod 121 and the switching rod 112 to reset.

[0039] During use, when cleaning the flash tank, first, the unfolded mounting rod 2 is inserted into the flash tank through the opening of the flash tank, and then the control knob 81 is turned. The control knob 81 rotates to drive the driving rod 82 threadedly connected thereto to rise, and the rising of the driving rod 82 drives the lifting plate 84 to rise. The rising of the lifting plate 84 drives the driving rack 85 disposed thereon to rise. The rising of the driving rack 85 drives the driving gear 86 engaged with it to rotate, and the rotation of the driving gear 86 drives the rotating shaft 63 to rotate. The rotation of the rotating shaft 63 drives the rotating rod 64 to deflect. The deflection of the rotating rod 64 drives the extension rod 66 and the cleaning plate 4 located on the extension rod 66 to deflect.

[0040] When the rotating rod 64 deflects, it drives the unfolding gear 75 located thereon to deflect. During the deflection process, the unfolding gear 75 rotates under the push of the pushing gear 72. The rotation of the unfolding gear 75 drives the fixed rod 74 to rotate. The rotation of the fixed rod 74 drives the sliding rod 77 to rotate synchronously. The rotation of the sliding rod 77 drives the unfolding gear 75 arranged thereon to rotate. The rotation of the unfolding gear 75 drives the deflection gear 79 arranged on the rotating shaft 2 67 and meshed with it to rotate, thereby driving the cleaning plate 4 to unfold and be parallel to the inner wall of the tank body.

[0041] When the distance between the cleaning plate 4 and the inner wall of the tank needs to be adjusted, the power block 96 is first rotated. The rotation of the power block 96 drives the pull rod 97 threadedly connected to it to rise. The rising of the pull rod 97 drives the traction rope 98 connected to it to rise, thereby driving the moving block 92 connected to the traction rope 98 to move, and then driving the extension rod 66 to extend out of the extension groove 65. At this time, the reset spring 93 is in a stretched state.

[0042] When the operator encounters a situation where attachments on the inner wall of the tank need to be cleaned during the process of rotating the mounting rod 2 to clean the inner wall of the tank, the cleaning plate 4 is first controlled to be close to the inner wall of the tank, and then the cleaning plate 4 is rotated. When the trigger plate 122 on the cleaning plate 4 contacts the solid attachments, the trigger plate 122 is pushed to deflect. When the trigger plate 122 deflects, the trigger rod 121 is driven to deflect synchronously. The deflection of the trigger rod 121 drives the switching rod 112 to rotate through the toothed belt wheel 124 and the toothed belt 125, so that the scraper 114 set on the switching rod 112 extends out to scrape off the solid attachments. At the same time, when the attachments are scraped off, the trigger plate 122 is no longer hindered, thereby driving the trigger rod 121 and the switching rod 112 to reset.

[0043] Example 2: Please refer to Fig.10 The present invention provides a technical solution: the scraper 114 is made of polytetrafluoroethylene. The scraper 114 made of polytetrafluoroethylene has an extremely low friction coefficient and excellent corrosion resistance, which can effectively avoid damage to the inner wall of the tank when scraping off attachments.
