Description

Technical Field

[0001] This utility model relates to the field of dust collection equipment, specifically to a dust collector for tablet pressing. Background Technology

[0002] Tablets are a common form of selenium products. Tablets have the advantages of high dosage accuracy and excellent chemical stability. Tablet compression is a pharmaceutical process that uses a tablet press as the core equipment to compress drug powder or granules into shape through mechanical pressure. During the tablet compression process, dust is inevitably generated. This dust dispersed inside the tablet press can cause the ingredients of different batches of drugs to mix, affecting the uniformity of the drug, causing uneven tablet surfaces, and affecting the uniformity of coating. Therefore, it is necessary to design a dust collector for tablet compression with good dust collection effect. Summary of the Invention

[0003] The purpose of this invention is to provide a dust collector for tablet pressing, which has the advantage of good dust collection effect.

[0004] The technical solution adopted is as follows:

[0005] A dust collector for tablet compression is installed inside a tablet compression chamber. It includes a dust collection unit, a storage box, and a negative pressure fan. The dust collection unit includes a mounting box with a mounting ring at one end. A mounting tube is coaxially rotatably installed inside the mounting ring and is rotatably and sealingly connected to the mounting ring. A drive mechanism connected to the mounting tube is installed inside the mounting box and is connected to a controller. A dust extraction pipe is vertically installed on the side of the mounting tube and is connected to a flexible steel wire hose. The flexible steel wire hose is inserted into the mounting box after passing around the mounting tube once. The storage box is connected to the flexible steel wire hose. The negative pressure fan has an exhaust pipe connected to the flexible steel wire hose, and a filter element is detachably installed inside the exhaust pipe.

[0006] Preferably, the driving mechanism includes a driving unit connected to a driving gear. The driving unit is disposed inside the mounting box, and a driven gear is coaxially disposed on the mounting tube inside the mounting ring. The driving gear meshes with the driven gear.

[0007] Preferably, the storage box is equipped with a discharge valve at the lower end and a germicidal ultraviolet lamp at the upper end.

[0008] Preferably, the dust extraction pipe is a universal pipe.

[0009] Preferably, the free end of the dust extraction pipe is connected to a dust collection hood.

[0010] Compared to existing technologies, the advantages are:

[0011] This invention utilizes a drive mechanism to drive the mounting tube to rotate the suction tube 360 ​​degrees, thereby suctioning the sides of the tablets after compression. The suction effect is excellent, and the mounting tube and mounting ring are connected in a rotating and sealed manner to prevent dust from entering between the mounting tube and the mounting ring and affecting the rotation.
