DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0022] The descriptions of "first", "second", etc. involved in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the technical features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0023] Reference to an "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] A specific embodiment of the present invention, as Figure 1 As shown, a kaolin viscosity concentration detection system is disclosed, comprising: The kaolin stirring device 101 is used to stir and mix the kaolin slurry to be tested, the pH adjuster, the dispersant and water; The pH adjustment detection device 102 is used to detect the real-time pH of the kaolin slurry to be tested, and control the amount of the pH adjuster added according to the real-time pH, so that the real-time pH of the kaolin slurry to be tested is within a preset pH range; The slurry viscosity regulating device 103 is used to detect the real-time viscosity of the kaolin slurry to be tested, and control the amount of dispersant added according to the real-time viscosity so that the real-time viscosity of the kaolin slurry to be tested is within a preset viscosity range; The viscosity concentration detection device 104 is used to detect the viscosity concentration of the kaolin slurry to be tested whose real-time viscosity is within a preset viscosity range and whose real-time pH is within a preset pH range.

[0025] In the embodiments of the present invention, viscosity refers to the ability of the slurry to resist flow, reflecting the magnitude of the friction in the slurry. The higher the viscosity of the slurry, the worse the fluidity. For example, a paste-like slurry has a high viscosity and hardly flows. It is affected by many factors such as the properties of the solid particles in the slurry (such as particle size, shape, surface properties, etc.), the properties of the liquid medium, temperature, and slurry concentration. Viscosity refers to the content of solid particles in the slurry. The presence of these particles makes the slurry viscous. Generally, the higher the viscosity, the greater the viscosity of the slurry.

[0026] In the embodiment of the present invention, the kaolin stirring device is used to stir and mix the kaolin slurry to be tested, the pH adjuster, the dispersant and the water, and can be a stirring barrel, a stirring box, etc., for fully stirring the kaolin slurry to be tested and other additives. The pH adjustment detection device can check the real-time pH of the kaolin slurry to be tested, and adjust the real-time pH of the kaolin slurry to be tested to a preset pH range. The slurry viscosity adjustment device is used to detect the real-time viscosity of the kaolin slurry to be tested, and adjust the real-time viscosity of the kaolin slurry to be tested to a preset target viscosity. The viscosity concentration detection device is used to calculate the viscosity concentration of the kaolin slurry to be tested after adjusting the pH and viscosity.

[0027] The kaolin viscosity concentration detection system provided by the present invention realizes the control of the pH value of the slurry through the automatic pH detection and the dosing control device, so that the system for testing the viscosity of the kaolin slurry is always at the optimal pH value of the slurry. Through the slurry viscosity adjustment device, the automatic testing of the minimum viscosity of the slurry and the automatic calculation of the viscosity concentration are realized, thereby reducing the workload of manual testing of the kaolin viscosity concentration; the system can automatically monitor the kaolin viscosity concentration to avoid human errors, thereby effectively improving the accuracy of the test.

[0029] In an embodiment of the present invention, when the pH adjustment detection device adjusts the pH of the kaolin slurry to be tested, the real-time pH of the kaolin slurry to be tested is measured by a pH detector. When the detected real-time pH of the kaolin slurry to be tested is less than the preset pH setting value, a certain dose of pH adjuster is added to the kaolin slurry to be tested. After the pH adjuster and the kaolin slurry to be tested are fully mixed, the real-time pH of the kaolin slurry to be tested is detected again. If the real-time pH of the kaolin slurry to be tested is still greater than the pH setting value, the above steps are repeated until the real-time pH of the kaolin slurry to be tested is less than or equal to the pH setting value.

[0030] Further, such as Figure 3 As shown, the slurry viscosity regulating device includes a viscosity detector 301 and a dispersant doser 302. The viscosity detector detects the viscosity of the kaolin slurry to be tested at a preset second time interval to obtain the real-time viscosity of the kaolin slurry to be tested. The dispersant doser is used to add a second dose of dispersant to the kaolin stirring device when the real-time viscosity is greater than the preset target viscosity, until the real-time viscosity is less than or equal to the preset target viscosity.

[0031] In an embodiment of the present invention, when the slurry viscosity adjusting device adjusts the viscosity of the kaolin slurry to be tested, the real-time viscosity of the kaolin slurry to be tested is measured by a viscosity detector. When the detected real-time viscosity of the kaolin slurry to be tested is greater than the preset target viscosity, a certain dose of dispersant is added to the kaolin slurry to be tested. After the dispersant and the kaolin slurry to be tested are fully mixed, the real-time viscosity of the kaolin slurry to be tested is detected again. If the real-time viscosity of the kaolin slurry to be tested is still greater than the target viscosity, the above steps are repeated until the real-time viscosity of the kaolin slurry to be tested is less than or equal to the target viscosity.
