Description

Technical Field

[0001] This invention relates to the field of concrete water-reducing agent production equipment, and more specifically, to a concrete water-reducing agent reaction device that facilitates adjustment of the reaction temperature. Background Technology

[0002] In the field of concrete engineering, compound polycarboxylate superplasticizers, with their excellent performance such as high water reduction rate and good slump retention, have become key admixtures for improving concrete performance. However, the production of compound polycarboxylate superplasticizers has extremely strict requirements on reaction temperature. Excessively high temperatures will cause the polymerization reaction rate to be too fast, leading to excessive molecular chain growth, resulting in uneven molecular weight distribution of the product and reducing the dispersibility and slump retention of the superplasticizer. Conversely, excessively low temperatures will cause the reaction to be slow or even stop, prolonging the production cycle and increasing production costs.

[0003] Based on the above, however, current reaction devices may have difficulty stabilizing the temperature at the set value due to the precision of the control system or interference from the external environment. This can lead to a certain degree of temperature fluctuation, which in turn can cause the water-reducing agent reaction rate to be unstable, affecting the reaction process and potentially increasing side reactions, thus reducing the purity and performance of the product. Utility Model Content

[0004] To address the aforementioned technical problems, this disclosure relates to a concrete water-reducing agent reaction device that facilitates temperature adjustment. This solves the problem of current reaction devices struggling to maintain a stable temperature at the set value, leading to unstable reaction rates. By employing a temperature control structure that combines heating and cooling, and using an intelligent temperature control module to precisely control the reaction temperature, the device can quickly and accurately adjust the temperature according to different stages of the reaction, keeping it within ±1℃ of the set value. This effectively avoids incomplete reactions or side reactions caused by temperature fluctuations, improving the product quality of the concrete water-reducing agent. Furthermore, the stirring and scraping structure ensures that the scraper plate is not in contact with the inner wall during stirring, preventing continuous wear and effectively protecting the inner wall of the reactor. Simultaneously, it allows for contact with the inner wall during subsequent cleaning, scraping away any material adhering to the inner wall. This not only protects the inner wall of the reactor but also prevents material residue from affecting subsequent batches of the reaction.

The driven pulley 3021 then drives the driven belt drum 302 to rotate, which in turn drives the stirring blades 3022 to stir and mix the materials. For cleaning, first turn off the motor 3011, then use a wrench to lock the limit block 3046 to prevent the driven belt drum 302 from rotating. Then, rotate the handle 3045 to drive the screw 304 to rotate. The screw 304 and the screw hole 3 on the moving ring 3041... 042 rotates and engages, the moving ring 3041 is limited and guided in the guide groove 3044 by the limiting protrusion 3043, so that the screw 304 drives the moving ring 3041 to move and be inserted into the insertion groove 3051 of the driving ring 305.

[0060] The specific usage and function of this embodiment are as follows:

[0061] In this invention, materials are fed into the vessel through the feed hopper 103, and the temperature is controlled at a set temperature. Simultaneously, the motor 3011 drives the drive shaft 3012 to rotate, which in turn drives the drive pulley 3013.

The driven belt drum 302 then drives the stirring blades 3022 to mix the materials. When the temperature is too low, the temperature sensor 204 sends a signal to the control terminal, which then controls the controller 2011 to turn on the electric heating element 201 to raise the temperature. When the temperature is too high, the control terminal controls the compressor refrigeration unit 203 to start, and the pump 2022 pumps coolant through the cooling circulation pipe 202 to lower the temperature inside the vessel. After mixing is complete, the valve 1041 is opened to release the coolant from the pump. The material is discharged through the discharge pipe 104. During cleaning, the motor 3011 is first turned off. Then, a wrench is used to lock the limit block 3046 to prevent the driven drum 302 from rotating. Then, the handle 3045 is rotated to drive the screw 304 to rotate. The screw 304 rotates and engages with the screw hole 3042 on the moving ring 3041. The moving ring 3041 is limited and guided in the guide groove 3044 by the limit protrusion 3043, thereby driving the screw 304 to drive the moving ring.
