Description

Technical Field

[0001] This utility model relates to the field of composite calcium carbonate coating agents, specifically to a production apparatus for composite calcium carbonate coating agents used in papermaking. Background Technology

[0002] Calcium carbonate is one of the most widely used inorganic mineral powder raw materials in the papermaking industry. As a commonly used filler and coating agent in the papermaking process, calcium carbonate can improve paper quality, increase paper opacity, and enhance production efficiency. The production of composite calcium carbonate coating agents requires thorough and uniform mixing of the materials. However, existing designs cannot adequately and uniformly mix the calcium carbonate and other materials, resulting in calcium carbonate adhering to the inner wall of the tank and calcium carbonate precipitate forming at the bottom, leading to low mixing efficiency. Therefore, those skilled in the art have provided a composite calcium carbonate coating agent production apparatus for papermaking to solve the problems mentioned in the background art.

The top cover is installed on the top of the tank, and the rotating motor is installed in the middle of the upper side of the top cover. The shaft of the rotating motor is connected to the rotating shaft, and the propeller blade is installed on the rotating shaft. The stirrer is provided on the inner wall of the tank, and multiple folded stirring plates are installed on the stirrer. An angled stirring plate is installed on the lower side of the stirrer, and multiple scraper teeth are installed on the outer wall of the angled stirring plate.
