Conveying device for thiamphenicol powder production

Abstract

The invention relates to a conveying device for thiamphenicol powder production. The conveying device comprises a tapered charging barrel and a conveying pipe, wherein the tapered charging barrel is connected with the conveying pipe through a square elbow; support legs are arranged under the tapered charging barrel; baseplates are arranged under the support legs; a motor and a transmission shaft are arranged in the middle of the conveying pipe; a belt pulley is fixed at the lower part of the transmission shaft; the motor is connected with the belt pulley through a belt; an impeller is fixed at the upper end of the transmission shaft; the impeller is arranged in the conveying pipe; and a discharge opening is formed in the left end of the conveying pipe. The conveying device for thiamphenicol powder production has the beneficial effects as follows: since the impeller is adopted to replace a conventional air pump to rotate to convey solid powder, the conveying efficiency of the solid powder is improved, powder leakage caused by insufficient anti-wind measures is avoided, and a smooth pharmaceutical process is guaranteed; and the conveying device is simple in structure, high in practicability and suitable for being popularized and used in the field of medical equipment.

Description

technical field [0001] The invention relates to the field of production equipment for thiamphenicol powder, in particular to a feeding device for the production of thiamphenicol powder. Background technique [0002] Thiamphenicol is a congener of chloramphenicol. Its antibacterial spectrum and antibacterial effect are similar to those of chloramphenicol. It has a broad-spectrum anti-thiamphenicol thiamphenicol microbial effect, including aerobic Gram-negative bacteria and Gram-positive bacteria , Anaerobes, Rickettsia, Spirochetes and Chlamydia. Thiamphenicol is bactericidal against the following bacteria: Haemophilus influenzae, Streptococcus pneumoniae and Neisseria meningitidis. It has only antibacterial effect on the following bacteria: Staphylococcus aureus, Streptococcus pyogenes, Streptococcus viridans, Group B hemolytic streptococci, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Salmonella typhi, Anaerobic bacteria such as Salmonella paratyphi, Shigel...

AI Technical Summary

Problems solved by technology

The following bacteria are commonly resistant to chloramphenicol: Pseudomonas aeruginosa, Acinetobacter, Enterobacter, Serratia marcescens, indole-positive Proteus, methicillin-resistant Staphylococcus, and Enterococcus; The pharmaceutical tablet press machine for the production of thiamphenicol powder is mainly used for the tablet process research in the pharmaceutical industry; the pharmaceutical tablet press machine for the production of thiamphenicol powder compresses the granules into circular, special-shaped and text- Automatic continuous production equipment for tablets, symbols, graphics; since the raw material of the tablet is a powdery solid, the existing conveying device of the tablet machine mainly uses the flow of the gas to drive the powder into the feeding bin through the air pump, the efficiency is low, and the windproof measures When there is a defect, it is easy to cause leakage of solid powder, which increases the safety hazard and cost of production
