Description

A chain-stirred digester Technical Field

[0001] The invention relates to the technical field of slaked lime production equipment, and in particular to a chain-stirring digester. Background Art

[0002] A quicklime digester is a special equipment for digesting quicklime into lime milk or lime powder. It is mainly used in industries such as steelmaking, chemical industry, metallurgy, papermaking, and electric field desulfurization. The industrial production of slaked lime uses a digester to produce slaked lime. The quicklime completes multi-stage digestion (a certain amount of water is mixed with quicklime) in the stirring and conveying trough of the digester to become fluffy lime powder. In the traditional structure of the existing digester, the multi-stage (three-stage, five-stage, seven-stage, etc.) stirring and conveying troughs for digesting quicklime are arranged side by side, and a single-axis propeller is used to convey the digestate in each stage of the stirring and conveying trough. The invention patent with application number 202011421622.3 discloses a quicklime digester, which has the following problems: 1. The rotating shaft is subject to large torque. In order to increase the strength, the shaft diameter and blade thickness are mostly increased. The equipment is heavy and the motor energy consumption is high. 2. Affected by the digestion time and spiral length, the length of each stage is generally less than six meters. Excluding invalid distances such as imports and exports, the available length of each stage is about 5 meters, which cannot be continuously advanced horizontally. It also requires multiple power and support structures. It is produced in a high-bottom end-to-end connection method. The supporting steel structure is large, the raw material inlet height is 5-10 meters, the cost is seriously wasted, and the amount of dust is large and the temperature loss is serious.

[0017] Furthermore, both ends of the digester body are bent upward.

[0018] The benefit of adopting the above technical solution is that during the digestion process, due to the high heights at both ends of the digester, the drive assembly is always located above the liquid level in the digester, reducing the impact of the raw materials on the drive assembly and increasing the service life of the drive assembly.

[0019] Furthermore, a discharge port is provided on the lower side of one end of the digester body, and the discharge port is covered with a discharge adjustment plate.

[0020] The benefit of adopting the above technical solution is that the discharge port is set to discharge the digested product, the height of the discharge port can be controlled by the discharge adjustment plate, and the depth of the material layer inside the digester can be adjusted to provide support for high specific surface area processes.

[0021] Furthermore, the transmission chains are arranged side by side along the length of the digestive cavity.

[0022] The benefit of adopting the above technical solution is that the transmission chains arranged side by side can improve the stability of the stirring element and extend the horizontal propulsion distance.

[0023] Furthermore, a feed inlet is provided above the digester body.
