[0003] At present, the pulping method of the popular wet mixing granulators on the market is fixed continuous pulping, which causes the material between the two paddles to easily form large particles, and to produce qualified pellets, it is necessary to A chopping knife is needed to chop the large particles. On the one hand, the speed of the chopping knife is high, which increases the cost of the equipment. On the other hand, it also increases the time of granulation, which is not conducive to improving the efficiency of the pharmaceutical factory.

Embodiment Construction
[0029] Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The description of the exemplary embodiments is for the purpose of illustration only, and in no way limits the invention and its application or usage.
[0030] The wet mixing granulator batch slurrying method of the present invention comprises:
[0031] Use the stirring paddle to stir the material in the material pot, and detect the position of the paddle in real time;
[0032] When the paddle is located under the slurry adding nozzle, the slurry adding nozzle is controlled to start adding slurry, and when the paddle passes under the slurry adding nozzle, the slurry adding nozzle is controlled to stop adding slurry.
[0033] Preferably, with the centerline of the stirring shaft as the center and the plane where the slurrying nozzle and the centerline of the stirring shaft are located as the reference plane, when the angle between the paddle and ...

The invention discloses an intermittent slurry addition method for a wet-type mixing granulator and the wet-type mixing granulator using the intermittent slurry addition method. The wet-type mixing granulator comprises a slurry addition nozzle, a material pan, a stirring paddle, a stirring shaft, a positioning sensor and a controller, wherein the slurry addition nozzle is arranged above the material pan and extends into the material pan; the stirring shaft is arranged below the material pan; the upper end of the stirring shaft penetrates through the bottom of the material pan and extends into the material pan and is connected to the stirring paddle; the positioning sensor detects positional information of the stirring paddle; and the controller judges position of paddles according to the positional information. By the intermittent slurry addition mode, slurry addition uniformity is greatly raised, dependency of the granulation effect on a chopping cutter is reduced, and granulation time is shortened. In addition, the structure is simple and cost is low.
Description
technical field [0001] The invention relates to the field of material granulation, in particular to a method for intermittently adding slurry to a wet mixing granulator and a wet mixing granulator using the method. Background technique [0002] The technical background related to the present invention will be described below, but these descriptions do not necessarily constitute the prior art of the present invention. [0003] At present, the pulping method of the popular wet mixing granulators on the market is fixed continuous pulping, which causes the material between the two paddles to easily form large particles, and to produce qualified pellets, it is necessary to A chopping knife is needed to chop the large particles. On the one hand, the speed of the chopping knife is high, which increases the cost of the equipment. On the other hand, it also increases the time of granulation, which is not conducive to improving the efficiency of the pharmaceutical factory. Contents ...
