Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agents, in particular to a polycarboxylic acid water reducing agent feeding device. Background Art

[0002] As the third generation of high-performance water reducers, polycarboxylic acid water reducers are currently the most widely used concrete admixtures due to their unique comb-shaped structure and mechanism of action, low dosage, high water reduction rate, small slump loss over time, green environmental protection, and strong molecular structure designability. However, the production conditions of polycarboxylic acid water reducers are more stringent than those of general naphthalene water reducers. If the batching error is large, the material concentration is uneven, and the dripping speed is unstable during the polymerization process, it will not only affect the quality stability of the polycarboxylic acid water reducer, but also lead to unqualified product quality and even safety accidents. At present, in the production process of water reducers, the dripping material often has uneven concentration, large metering error, and unstable dripping process due to the lack of stirring and metering equipment in the dripping tank. As a result, the polymerization process of the polycarboxylic acid water reducer is unstable and uncontrollable during the synthesis reaction, which seriously affects the quality stability and performance of the polycarboxylic acid water reducer. The above problems need to be solved urgently. Utility Model Content

[0014] like Figure 1-2As shown, a polycarboxylate water-reducing agent feeding device comprises a dropping tank 3, a motor 1 and an electronic scale 5. The dropping tank 3 has a feeding port on the top, and a feeding port cover plate 2 is provided on the feeding port. The dropping tank 3 is provided with a stirring paddle 4, and the stirring paddle 4 is connected to an external motor 1. The top of the dropping tank 3 is connected to a water inlet pipe 11 and a feeding pipe 12. A fixing frame 10 is provided outside the dropping tank 3, and the fixing frame 10 and the electronic scale 5 are fixed on an operating platform 9. A feeding pipe 6 is connected to the side of the dropping tank 3, and the other end of the feeding pipe 6 is connected to a peristaltic pump 8 and then connected to a reactor. The feeding pipe 6 is connected to the peristaltic pump 8 through a silicone hose 7. The water inlet pipe 11, the feeding pipe 12 and the feeding pipe 6 are respectively provided with a valve 131, a valve 2 132 and a valve 3 133. The operating platform 9 outside the dropping tank 3 is provided with multiple steps 14 for easy operation by workers.

[0015] The specific operation is as follows: the dropping tank 3 is used to configure and store various raw materials to be added, the electronic scale 5 is used to measure the weight of each raw material, the solid raw material is added through the feeding port 2 on the upper part of the dropping tank 3, and the stirring paddle 4 is driven by the motor 1 to homogenize the material in the dropping tank 3 to ensure the uniformity of the dropping material. The peristaltic pump 8 is used to control the amount and time of the dropping material added to the reaction per unit time.

[0016] Ingredient metering: add water to the dripping tank 3 through the water inlet pipe 11, observe the weight displayed on the electronic scale 5, and close the water inlet valve 131 when the formula weight is reached; add acrylic acid to the ingredient tank 3 through the feed pipe 12, observe the weight displayed on the electronic scale 5, and close the water inlet valve 2 132 when the formula weight is reached; add ascorbic acid and other solid raw materials through the feed port 2.

[0017] Stirring and homogenizing: After all types of raw materials have been added to the dropping tank 3, turn on the motor 1 and drive the stirring paddle 4 to start stirring to mix the materials in the storage tank 3 evenly. The stirring time is about 10 minutes to ensure that all solid materials are completely dissolved. After all materials are mixed evenly, turn off the stirring, and the materials in the dropping tank 3 are evenly distributed from top to bottom.

[0018] Feeding speed control: According to the total weight of the material in the dropping tank 3 and the feeding time specified in the formula, the feeding speed of the material is calculated, and the feeding speed is controlled by adjusting the speed of the peristaltic pump 8. Further operation: open the valve 3 133 on the feeding pipe 6, adjust the speed of the peristaltic pump 8 to the set speed, and start to add the material in the dropping tank 3 to the reactor at a uniform speed.

[0019] Since the concentration of the material in the dropping tank 3 is uniform from top to bottom, and the speed of adding the material into the reactor is also uniform through the control of the peristaltic pump 8, the stable progress of the synthesis reaction can be ensured, the polymerization process is stable and controllable, the quality stability of the polymerization product is improved, and unqualified products are avoided.
