Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical vibrating screens, and in particular to a graded vibrating screen for pharmaceutical manufacturing. Background Technology

[0002] A pharmaceutical grading vibrating screen is a screening device that uses vibration to separate materials. It is widely used in the pharmaceutical industry for screening, grading, and removing impurities from pharmaceutical raw materials, intermediates, and finished products. It can effectively separate particles of different sizes to meet the stringent particle size requirements in pharmaceutical production.

[0003] In pharmaceutical manufacturing, the grading vibrating screen, as a key screening device, often encounters dust generation during material discharge. This phenomenon not only pollutes the environment but also poses a threat to the health of operators. Specifically, when materials are discharged at high speed through the discharge pipe, fine particles are lifted up by the airflow, forming dust. This dust is not only difficult to control but may also spread into the surrounding environment, adversely affecting air quality.

[0004] To address this issue, the traditional method is to install dust covers on the discharge pipes. However, while dust covers can reduce dust generation to some extent, they also present several inconveniences. First, the installation and removal of dust covers are relatively cumbersome, requiring significant manpower and time. In the fast-paced environment of pharmaceutical production, this inconvenience can reduce production efficiency and increase production costs. Second, the sealing performance of dust covers is difficult to guarantee, especially after prolonged use, when leaks may occur, leading to a recurrence of dust problems. Furthermore, the maintenance and cleaning of dust covers are relatively complex, requiring regular cleaning and replacement to ensure their proper functioning. Utility Model Content

[0005] The main objective of this invention is to provide a grading vibrating sieve for pharmaceutical manufacturing, which can effectively solve the problems mentioned in the background art.

A dust cover is installed at the upper end of the protective frame 3 to prevent dust during the screening operation. Precise grading screening is achieved by driving the vibrator 7. The vibrator 7 is connected to one end of the protective frame 3. Through its precise control, it drives the first grading screening mesh 5 and the second grading screening mesh 6 to perform regular movements, thereby achieving the grading screening of drugs.

[0028] To ensure smooth discharge of the graded and screened drugs, the equipment is also equipped with a first discharge pipe 8 and a second discharge pipe 9, which are installed at the lower end of the protective frame 3. The discharge pipes effectively discharge the graded and screened drugs into their respective collection tanks 12. The inlet 4 is located at the other end of the first grading and screening mesh cover 5, facilitating drug feeding by the operator.

[0029] To further enhance the stability and safety of the equipment, a base 1 is also provided at the lower end of the support frame 2. The upper end of the base 1 is designed with a lower arc-shaped ring 15 facing the first discharge pipe 8 and the second discharge pipe 9, and an insertion hole 16 is opened on its side wall. A collection tank 12 is placed at the first discharge pipe 8 and the second discharge pipe 9 and the corresponding lower arc-shaped ring 15.
