[0002] The slurry has a huge impact on the quality of the product in the entire production process. Therefore, the state of the slurry needs to be frequently tested in the slurry process. For example, in the production of lithium batteries, the resistance of the slurry of the raw materials in the slurry mixing process needs to be tested to see if the slurry meets the requirements in order to find problems in advance. Currently, most of the tests are done by sampling the slurry and then putting it into a special instrument for offline testing, which has low work efficiency. At the same time, some existing online slurry detection devices have the problem of difficulty in controlling the slurry conveying speed, resulting in poor detection accuracy. Utility Model Content

DETAILED DESCRIPTION

[0021] Combination Figures 1 to 3As shown, the present embodiment provides a slurry testing system, which is suitable for being connected to a slurry tank 8, and comprises: a pump body 2, a detection module 3, a cleaning bucket 5, and a waste bucket 4, wherein the input end of the pump body 2 is suitable for switching connection between the slurry tank 8 and the cleaning bucket 5, and the output end of the pump body 2 is connected to the detection module 3, and the detection module 3 is configured to detect the resistance of the slurry; the output end of the detection module 3 is suitable for switching connection between the slurry tank 8 and the waste bucket 4, so that the pump body 2 and the detection module 3 form a closed-loop detection circuit with the slurry tank 8, or the pump body 2 and the detection module 3 form a cleaning circuit with the cleaning bucket 5 and the waste bucket 4.

[0022] Continue to combine Figure 1 to Figure 2 As shown, the situation of applying the detection circuit of the slurry testing system is demonstrated, the pump body 2 and the slurry tank 8 are connected through the first pipe 9, the pump body 2 and the detection module 3 are connected through the third pipe 12, and the output end of the detection module 3 and the slurry tank 8 are connected through the fourth pipe 13. In this embodiment, a first control valve 10 is provided on the first pipe 9 to control the opening and closing of the slurry at the beginning of the detection loop. The pump body 2 preferably adopts a screw pump to facilitate the control of the flow rate of the slurry in the detection loop. The slurry enters the input end of the pump body 2 from the slurry tank 8 through the first pipe 9, and then enters the detection module 3 from the output end of the pump body 2, and is detected by the detection module 3, and finally flows back to the slurry tank 8 through the fourth pipe 13. Preferably, a second control valve 6 is provided at the connection between the detection module 3 and the fourth pipe 13, such as a ball valve, which can control the opening and closing of the detection loop at the end. When the second control valve 6 is opened, a flow loop is formed, which can be used to detect the dynamic index of the slurry. When the second control valve 6 is closed, the pump body 2 is also closed after sufficient slurry is input into the detection module 3, which can be used to detect the static index of the slurry, thereby realizing two test modes and improving the functionality of the test system. In this embodiment, the detection module 3 is an existing detection device, and a device for testing resistance is used here. In order to achieve other test purposes, other detection devices can also be used.

[0023] Continue to combine Figure 3As shown, the present slurry testing system is shown in which the cleaning circuit is applied. The pump body 2 is connected to the cleaning bucket 5 through a second pipe 11, the pump body 2 is connected to the detection module 3 through a third pipe 12, and the output end of the detection module 3 is connected to the waste bucket 4 through a fifth pipe 14. In this embodiment, a booster pump 7 is provided on the second pipe 11, and the booster pump 7 is used to ensure the pressure during flushing and control the opening and closing of the cleaning circuit to ensure that the flushing is clean and there is no slurry residue. The cleaning liquid is drawn from the cleaning bucket 5 to the second pipe 11 through the booster pump 7 to enter the input end of the pump body 2, and then flows from the output end of the pump body 2 into the detection module 3 for cleaning, and finally discharged to the waste bucket 4 through the fifth pipe 14. When the cleaning circuit is turned on, the detection circuit pipeline is closed or removed, and vice versa when the detection circuit is turned on, the cleaning circuit pipeline is closed or removed, so as to avoid mutual influence.

[0024] In this embodiment, the bottom of the slurry testing system is arranged on the movable cart 1, which is convenient for moving the entire testing system and can be applied to a plurality of different workstations, with strong flexibility. A control system 15 is also arranged on the movable cart 1, and the control system 15 is electrically connected to the detection module 3, the pump body 2, the first control valve 10, the second control valve 6 and the booster pump 7. Here, the control system can be an external control module computer, etc., and the electrical connection form is also an existing wired / wireless connection (omitted in the figure), which is used for automatic control and intelligent control of the entire testing system, and a display screen can also be set to display monitoring values, etc.

[0025] Through this embodiment, the functionality of the test system is improved to meet the user's detection needs. The electrical properties of the battery material slurry can be detected online, and the flow rate and flow rate of the pump body can be controlled through the control system. Since the resistance results detected by the detection module at different flow rates are also different, different working parameters of slurry stirring can be simulated to obtain different analysis results, providing a reference for slurry process design. When the detection circuit is used up, the cleaning circuit can be switched for cleaning, and the slurry residues in the pump body and the detection module can be cleaned together and flushed into the waste barrel for recycling, thereby improving work efficiency.
