Description

Technical Field

[0001] The utility model relates to the technical field of polycarboxylate water reducer production, in particular to a polycarboxylate water reducer drying device. Background Art

[0002] Polycarboxylate water reducer is a common additive used in the concrete production process. After production, the water needs to be evaporated to extract powdered dry polycarboxylate water reducer.

[0003] Industrially produced polycarboxylic acid water reducers are generally supplied as 40% aqueous solutions, that is, mother liquors, which have disadvantages such as high cost and inconvenience in storage and transportation. In addition, some engineering and technical fields must use solid admixtures, such as dry-mix mortar and high-performance ceramic manufacturing. Therefore, the preparation of solid polycarboxylic acid water reducers has important practical application significance.

[0004] The Chinese patent with the existing patent application number 202220300789.2 discloses a polycarboxylate water-reducing agent drying device, including a heating chamber, a stirring assembly, and a heating assembly. The heating chamber is an inverted hollow truncated cone, and the top of the heating chamber is provided with a feed port and a steam exhaust port, and the bottom of the heating chamber is provided with a discharge port; the stirring assembly includes a motor, a reducer, a stirring shaft and a stirring rod, and the motor and the reducer are arranged at the top of the heating chamber, and the output end of the motor is connected to the input end of the reducer. The stirring shaft is vertically arranged in the heating chamber, and the top of the stirring shaft is connected to the output end of the reducer. A number of stirring rods are evenly and horizontally arranged on the outside of the stirring shaft, and the motor is used to drive the reducer to drive the stirring shaft to rotate. The drying device of the utility model can fully dry the polycarboxylate water-reducing agent with high drying efficiency to avoid rework due to substandard drying quality.

[0005] However, the polycarboxylate water-reducing agent drying device still has some shortcomings in actual use. For example, in the initial stirring process, only the stirring blade is used for stirring and drying, which not only easily causes the polycarboxylate water-reducing agent to adhere to the inner wall of the drying chamber, thereby causing the adhered part to be unable to be fully dried, but also fails to fully break up the polycarboxylate water-reducing agent when drying it. Once the stirring is insufficient, the agglomerated and adhered part of the polycarboxylate water-reducing agent cannot be effectively dried, resulting in low drying efficiency.
