Embodiment Construction

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation of the present invention in detail in conjunction with the accompanying drawings.

[0022] Such as figure 1 As shown, the stirring device of the dedusting digester includes a shell 1, a raw material inlet 2, a finished product outlet 3 and a digestion system 4. The upper part of the shell 1 is provided with a raw material inlet 2, the bottom of the shell 1 is provided with a finished product outlet 3, and the inside of the shell 1 is provided with a digestive system. 4. Digestive system 4 is a three-level digestive system. The three-level digestive system has the same structure and is arranged inside shell 1 from top to bottom at a certain angle. The inclination angle is a, Sina=H / L, when the length L of the digestive system 4 is constant, the greater the elevation H is, the greater the value of Sina is, and the compone...

Abstract

The invention provides a stirring device of a dedusting digester. In the oblique digester, due to the action of gravity component force of digested lime, friction resistance is reduced, thrust required by movement of digested lime is reduced too, and abrasion of blades of the digester is reduced. Under the condition that driving force is unchanged, the transmission capacity of the digester is improved, most lime becomes powder and adheres to the digester in the third stage of digestion, powder can move fast automatically, and lime not digested completely continues to stay at the bottom of a cavity of the digester to be digested. The length of the digester can be increased appropriately so as to prolong lime digestion time; meanwhile, an outlet of the digester can be enlarged to avoid digester blocking caused by unsmooth discharging. A detachable alloy blade device is adopted, time and labor are saved, and using is convenient and quick. Due to the fact that a framework oil seal spindle is replaced with a labyrinth gland, sealing effect is good, maintenance is not needed at all, and operation and using are more convenient.

Description

technical field [0001] The invention relates to the technical field of calcium hydroxide production, in particular to a stirring device for a dedusting digester. Background technique [0002] Dust removal digester is an indispensable process and equipment for calcium hydroxide production enterprises. From the low efficiency of manual digestion at the beginning, the poor environment without dust removal equipment to the mechanized ash, the technological progress and development of pulse bag dust removal. Traditional processes and equipment are no longer suitable for environmental protection and energy saving requirements. Especially for pulse dust removal, the cost is high and the maintenance cost is high. In the case of wet dust removal, the cloth bag is sticky and difficult to clean. Lime calcium oxide is highly corrosive and directly affects the life of the bag. Usually replaced once or twice a year. There are many problems with traditional digesters, such as: [000...
