Shaking type screening device for drug processing

Abstract

The invention discloses a shaking type screening device for drug processing. The screening device comprises a casing, a stirring structure, a telescopic supporting rod and a screen plate; perpendicular sliding grooves are symmetrically embedded in the lower parts of the two sides of the casing; two ends of the screen plate movably extend into the perpendicular sliding grooves; the screen plate isglidingly connected with the perpendicular sliding grooves; the stirring structure comprises a rotating shaft, rotating frames and a motor; the rotating shaft is radially rotationally arranged betweenthe front side wall and the back side wall inside the casing; six groups of the rotating frames distributed at equal angles are welded on the periphery of the rotating shaft; and when the rotating frames are symmetric on two sides and are kept horizontal, the upper surface of the screen plate and the lower end of the rotating frames movably fit each other. According to the screening device, the lower ends of the rotating frames fit and press the screen plate continuously and then leave to withdraw the pressure during rotation, so that the screen plate shakes continuously, the screening efficiency of medicinal materials can be further improved, the effect one-way rotation for residue discharging can be formed, and the screening device is convenient to use.

Description

technical field [0001] The invention relates to a medicine processing device, in particular to a shaking type medicine processing and screening device. Background technique [0002] In the process of drug processing, especially in the processing of traditional Chinese medicine, the drug is generally crushed to a certain extent. The advantages of this processing method are: increasing the surface area of ​​the drug and promoting the dissolution of the drug; it is beneficial to the preparation of various drug dosage forms; Dissolution of active ingredients; easy to deploy, take and exert medicinal effects; easy to dry and store fresh medicinal materials. [0003] Therefore, centralized sieving is required after crushing to ensure the crushing quality, and the existing sieving is generally manual sieving, and mechanical vibration sieving is rarely used. These manual sieving have low efficiency, while mechanical sieving is more efficient. Higher, but it is not easy to discharge...

[0003] Therefore, centralized sieving is required after crushing to ensure the crushing quality, and the existing sieving is generally manual sieving, and mechanical vibration sieving is rarely used. These manual sieving have low efficiency, while mechanical sieving is more efficient. Higher, but not easy to discharge drugs that cannot be screened
