Description

Technical Field

[0001] The utility model belongs to the technical field of pulping, and in particular relates to a silica gel pulping pH value monitoring system. Background Art

[0002] In the prior art, cyclic pulping and pH value detection are often not taken into account at the same time. For example, the silica gel pulping system usually uses a separate cyclic pulping device and a pH value detection device, which requires pulping and sampling and testing to be performed separately during the production process, which is cumbersome and inefficient. At the same time, the sampling and testing process often has a time delay, and cannot reflect the pH value changes of the silica gel during the pulping process in real time, thus affecting the stability of product quality.

[0003] Secondly, since there is no organic combination of cyclic beating and real-time pH value detection, the beating process needs to be stopped frequently for sampling and testing during the production process, which not only increases the labor intensity of operators, but also leads to a waste of production time and reduces the overall production efficiency; since the pH value of silica gel cannot be detected in real time, pH value abnormalities may not be discovered in time during the production process, resulting in unstable product quality. In addition, the traditional beating system has a limited degree of uniform mixing of silica gel, which also affects the final quality of the product. Utility Model Content

The silica gel beating process may be included: the silica gel is mixed and beated in the tank body 12 by the stirring rod 3 driven by the stirring motor 2. Reflux process: After pulping, the silica gel passes through the reflux pipe 7. Under the action of the reflux pump 71, part of the silica gel can flow back to the top of the cover body 11 for cyclic pulping to ensure the uniformity of the pulping. pH value detection process: During the reflux process, part of the silica gel enters the detection container 91 through the pH value detection tube 9. At this time, the steam in the steam pipe 10 is controlled by the steam valve 102 to provide a constant temperature environment for the detection container 91 to ensure the accuracy of the measurement of the pH meter 92. The silica gel contacts the probe of the pH meter 92 in the detection container 91 to measure the pH value of the silica gel.
