Description

Technical Field

[0001] The invention relates to the technical field of medicinal material processing equipment, in particular to wet granulation equipment. Background Art

[0002] Wet granulation equipment is used to make powdered or granular materials into granular or spherical particles in a wet environment. In the pharmaceutical industry, wet granulation equipment can make drug raw materials into capsules, pills, tablets and other dosage forms, improve the taste and storage properties of drugs, and facilitate patients to take and store; During the use of the wet granulation equipment, the medicinal raw materials and the adhesive are usually added into the mixing box together, and then the driving device drives the stirring blades to stir and mix the medicinal raw materials and the adhesive. After the medicinal raw materials and the adhesive are mixed into a wet soft material, the wet soft material is injected into the conveying pipe. Then, under the push of the spiral blade, the wet soft material can be moved inside the conveying pipe, and then discharged through the discharge hole. Finally, the wet granulation equipment drives the cutting blade to cut the extruded wet soft material through the driving device, and finally obtains the required medicinal granules; For example, a high-speed wet granulation device disclosed in the prior art with the authorization publication number CN 210965008 U includes an equipment base, a transmission control device is installed on the equipment base, a pot body is connected to the transmission control device, a cutting device is arranged in the pot body, a cutting device is connected to the cutting device, a stirring device is arranged at the bottom of the pot body, and a master controller is connected to the transmission control device and the cutting control device. Thus, relying on the cutting device in the pot body, the materials and the adhesive are mixed more evenly and fully by using the vertically distributed cutters.

[0003] In the process of operation, the existing wet granulation equipment can drive the stirring blades to stir and mix the medicinal raw materials and the adhesive through the driving device, but the stirring method is relatively simple, which leads to a long time for mixing. Some wet granulation equipment use multiple sets of driving devices to drive the stirring blades to stir at multiple angles at the same time. Although this method shortens the mixing time, the cost is relatively high. In the process of wet granulation equipment using spiral blades to drive the wet soft material to move, due to the large viscosity of the wet soft material, some of the wet soft material will accumulate inside the conveying pipe. After a long period of work, the wet soft material blocks the conveying pipe. The driving device drives the hammer to knock on the conveying pipe. Although this method can prevent the wet soft material from accumulating inside the conveying pipe, the long-term knocking will also reduce the service life of the conveying pipe. For this reason, we propose a wet granulation equipment. Summary of the invention
