[0021] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0022] Example 1, see Figures 1-5 A battery slurry pipeline cleaning device, comprising inert gas

[0023] The inert gas booster and the fishbone-shaped propulsion component are detachably connected at the first cleaning port at one end of the main pipeline for conveying battery slurry. The inert gas booster is used to drive the fishbone-shaped propulsion component to move within the main pipeline.

[0024] A wall-mounted residual material collection device is movably installed at the second cleaning port at the other end of the main pipeline; sediment slurry collection devices are also movably installed at both the first and second cleaning ports; and pipeline sealing components are detachably installed at the first and second cleaning ports of the main pipeline.

[0025] A feed pipe is integrally connected to the side near the first cleaning port, and a discharge pipe is integrally connected to the side near the second cleaning port; the feed end is fixedly connected to the feed pipe through a feed valve, and the discharge end is fixedly connected to the discharge pipe through a discharge valve; a first normally open valve is provided on the main pipe between the feed pipe and the discharge pipe near the first cleaning port, and a second normally open valve is provided near the second cleaning port.

[0026] When a production cycle is nearing its end and the slurry delivery pipeline needs cleaning, such as Figure 2 As shown, first close the feed valve, discharge valve, first normally open valve, and second normally open valve. Remove the sealing parts between the first and second cleaning ports. Manually clean the sediment between the feed pipe and the first cleaning port, and between the discharge pipe and the second cleaning port, into the sediment collection device. Then proceed as follows: Figure 4 As shown, the fishbone-shaped propeller is placed into the first cleaning port of the main pipeline. The inert gas booster is connected to the first cleaning port. At this time, the first normally open valve and the second normally open valve are opened, and the inert gas compressor is started to generate high-pressure gas to push the fishbone-shaped propeller along the inside of the main pipeline toward the second cleaning port. This causes the fishbone-shaped propeller to push the wall-mounted slurry out of the second cleaning port of the main pipeline and into the wall-mounted residual material collection device.

[0027] Using an inert gas booster can reduce the possibility of oxygen and moisture in the air reacting with the slurry in the pipeline under high pressure, causing chemical or physical changes that could lead to slurry degradation. This reduces the waste of resources caused by the alteration of the slurry's physicochemical properties, which could result in its disposal or the need for further processing before it can be reused in the production process.

[0028] The fishbone-shaped propulsion component, with its multi-layered scraping structure, can better clean the slurry adhering to the pipe walls.

[0029] This device enables the cleaning of slurry conveying pipelines. Through the cooperation of personnel and various devices, it can clean up deposited slurry and slurry adhering to the walls separately, greatly reducing slurry loss and the possibility of slurry used in this production cycle contaminating the slurry used in the next production cycle. This further improves product quality, saves costs, and is safe and environmentally friendly.

[0030] Example 2: The battery slurry pipeline cleaning device provided in this example is an improvement on Example 1 with the following modifications:

[0031] Furthermore, preferably, a strong magnet is installed inside the fishbone-shaped propulsion component as a positioning device; and several Hall sensors are installed outside the main pipe as position sensors to detect the position of the positioning device.

[0032] Furthermore, the preferred inert gas booster is a nitrogen booster.

[0033] Furthermore, the fishbone-shaped propulsion component is preferably made of rubber; the fishbone-shaped propulsion component is interference-fitted with the interior of the main pipe.

[0034] Furthermore, a first pipeline pressure detection element is provided near the first normally open valve along the slurry flow direction; a second pipeline pressure detection element is provided near the second normally open valve along the slurry flow direction.

[0035] This implementation method utilizes several Hall effect sensors installed on the exterior of the main pipeline. As the inert gas booster propels the fishbone-shaped propeller within the main pipeline, the sensors monitor the strong magnets inside the propeller, thus determining its position. The Hall effect sensors transmit position signals, which are then fed back to a visualization terminal, enabling continuous monitoring of the propeller's movement within the main pipeline. Using a nitrogen booster as the high-pressure gas source for the fishbone-shaped propeller further reduces pipeline cleaning costs. The fishbone-shaped propeller, made of rubber and designed with an interference fit to the main pipeline, further enhances the effectiveness of cleaning the slurry adhering to the pipeline walls under the pressure of high-pressure nitrogen provided by the nitrogen booster.

[0036] Using this implementation method, when a production cycle is nearing its end and the slurry conveying pipeline needs cleaning, such as... Figure 2 As shown, first close the feed valve, discharge valve, first normally open valve, and second normally open valve. Remove the pipe sealing parts at the first and second cleaning ports. Manually clean the slurry deposited at both the feed pipe and the main pipe between the first and second cleaning ports into the slurry collection device. Close the pipe sealing parts at the second cleaning port and open the discharge valve. Then proceed as follows: Figure 3 As shown, a fishbone-shaped propeller is placed into the first cleaning port of the main pipeline. The nitrogen booster is connected to the first cleaning port. At this time, the first and second normally open valves are opened, and the nitrogen compressor is started to generate high-pressure gas, propelling the fishbone-shaped propeller along the main pipeline towards the second cleaning port. During this movement, the first pipeline pressure sensor monitors the air pressure between the nitrogen compressor and the fishbone-shaped propeller, and the second pipeline pressure sensor monitors the air pressure between the fishbone-shaped propeller and the pipeline sealing component at the second cleaning port, feeding back the air pressure information to the visualization terminal. Under the pressure difference, the fishbone-shaped propeller pushes most of the wall-mounted slurry through the discharge valve to participate in the final production process. Since this portion of the wall-mounted slurry does not flow out of the pipeline and is not exposed to air, it does not need to undergo further testing of its physicochemical properties or processing before passing through the discharge valve and participating in the final production process of this cycle. This further reduces the waste of resources caused by changes in the physicochemical properties of the wall-mounted slurry, which could lead to its disposal or require further processing before re-entering the production process.

[0037] After receiving feedback from the position sensor via a visual terminal indicating that the fishbone-shaped propeller has passed through the second normally open valve, the second normally open valve is closed, and the nitrogen booster is activated. At this time, the second pipeline pressure detection device provides feedback on the air pressure information between the second normally open valve and the sealed part of the pipeline at the second cleaning port. When the pressure difference between the feedback air pressure information and the external atmospheric pressure reaches a safe value, the discharge valve is closed, and the sealed part of the pipeline at the second cleaning port is opened. The safe pressure difference formed in the pipeline can then slowly push the fishbone-shaped propeller to push the remaining wall-mounted slurry into the wall-mounted residue collection device. When reused, its physicochemical properties are tested, and if they meet the standards, it is reused in the production process. This method is safe, efficient, and eliminates the problem of unknown excessive pressure differences causing slurry to splash from the second cleaning port, resulting in troublesome cleaning, material waste, and potential safety accidents.

[0038] Example 3 The battery slurry pipeline cleaning device provided in this example is an improvement on Example 2 with the following modifications:

[0039] Furthermore, the inner diameter of both the feed pipe and the discharge pipe is smaller than the inner diameter of the main pipe.

[0040] Furthermore, the angle between the feed pipe and one end of the main pipe where the first cleaning port is located is greater than 0 degrees and less than or equal to 90 degrees; the angle between the discharge pipe and one end of the main pipe where the second cleaning port is located is greater than or equal to 90 degrees and less than 180 degrees.

[0041] Furthermore, both the first normally open valve and the second normally open valve are valves that allow the fishbone-shaped propulsion component to pass smoothly, with ball valves being preferred.

[0042] This implementation method further enables the fishbone-shaped propulsion component to move smoothly within the main pipeline, reducing the possibility of the fishbone-shaped propulsion component accidentally getting stuck in the pipeline under the push of high-pressure gas.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
