Description

Technical Field

[0001] The utility model relates to the technical field of wet granulators, in particular to a wet granulator with a reverse-thrust thread stirring shaft. Background Art

[0002] A wet granulator is used to grind damp powder into the desired granules or to crush dry bulk materials into the desired size. The wet granulator operates as follows: Powdered materials are placed in the granulator's feed pot and mixed evenly. A liquid binder or dissolving fluid is rapidly sprayed in from the top, while the powdered materials are vigorously stirred and chopped by a cutting blade. The granules produced by the wet granulator are hard, robust, and round.

[0003] Wet granulators are widely used in the pharmaceutical, food, and chemical industries to produce granular pharmaceuticals, fertilizers, foods, and chemicals. Their advantages include high production efficiency, uniform granulation, and easy quality control. They are also highly adaptable, adapting to granulation processes with varying raw materials and process requirements.

[0004] The stirring mechanism is a crucial component of a wet granulator. Its function is to stir and mix the raw materials in the feed pot during operation, ensuring full contact between the raw materials and the slurry. Simultaneously, a sprayer evenly applies liquid additives to the raw materials, gradually wetting and bonding them. The wet granules then enter a dryer, where the moisture is evaporated through heating or other methods, gradually hardening the granules. Finally, the resulting granules are discharged through a discharge port. However, in existing wet granulators, dust particles can easily enter the rotating gap of the stirring mechanism's drive shaft during pulverization, causing the drive shaft to jam and seriously affecting the wet granulator's processing stability. Utility Model Content

[0005] The purpose of the utility model is to provide a wet granulator with a reverse-threaded stirring shaft, aiming to solve the problem that dust particles in the existing wet granulator easily enter the rotating gap of the stirring mechanism drive shaft when crushing dry materials, thereby causing the drive shaft to get stuck.

[0006] To achieve the above-mentioned purpose, the utility model provides a wet granulator with a reverse-threaded stirring shaft, comprising a frame, a material pot box body is provided on the top of the frame, and a stirring device, wherein the stirring device is located in the material pot box body;

[0007] The stirring device includes a stirring shaft and a stirring motor, the stirring shaft is connected to the output shaft of the stirring motor, the stirring motor is arranged below the frame, and a stirring paddle seat is provided on the top of the stirring shaft;

[0008] A reverse thrust thread is provided between the stirring paddle seat and the shaft seat;

[0009] The output shaft of the stirring motor is connected to the stirring device and drives the stirring device to rotate.
