Description

Technical Field

[0001] The utility model relates to the technical field of polycarboxylate water reducers, in particular to a novel polycarboxylate water reducer test pre-reactor. Background Art

[0002] Polycarboxylate water reducer has an artificially designed molecular structure, with a high proportion of effective ingredients and a concentrated molecular weight range. Therefore, compared with other water reducers, polycarboxylate water reducer not only has a high water reduction rate and a long slump retention, but also has a smaller dosage. In the production process of polycarboxylate water reducer, in order to improve production quality and production efficiency, it is usually necessary to use a special pre-reactor to operate, but the existing reactors generally do not have solution metering and temperature control functions, which is not convenient for ensuring the accuracy of production ratios and production efficiency.

[0003] For example, a polycarboxylic acid water-reducing agent pre-reactor disclosed in the authorization announcement number CN210279171U includes a horizontally installed annular tube connected in series with an axial flow pump, and a heating sleeve is installed outside the annular tube; the top of the annular tube is connected to a feed pipe with a feed valve, and the bottom is connected to a discharge pipe with a discharge valve; a number of vortex channels are connected in series at intervals inside the annular tube, and more than one constant temperature heater is installed on the outer wall of the heating sleeve. The utility model adopts an annular tube for circulating mixing, and the mixing temperature can be controlled by a constant temperature heater to achieve precise temperature control. At the same time, the mother liquor inside the annular tube is constantly circulating during the water bath heating process, and the heating sleeve is a comprehensive heating of the annular tube, which can avoid the problem of excessive local temperature caused by direct heating. Since the materials are all circulated and mixed in the annular tube, the mixing synchronization is high, and the time and degree of mixing of each part are the same, so that it has a higher uniformity. However, the utility model lacks effective metering and cooling functions, which makes it difficult to ensure the ratio accuracy of the polycarboxylic acid water-reducing agent and effectively control the excessively high temperature during the reaction process. To this end, we proposed a new polycarboxylic acid water-reducing agent test pre-reactor, which solves the ratio metering and temperature control problems and improves the production quality and practical effect of the utility model.
