Problems solved by technology

[0003] When the pharmaceutical intermediate is used or prepared, it needs to be fully mixed before it can be used; in this process, the mixing device is indispensable, and the mixing device currently used is very important for pharmaceutical The mixing rods used for intermediate mixing are often fixed and integrated with the rotating shaft, so that the stirring rods will not move during stirring, so that the raw materials cannot be fully mixed, and it takes a long time to complete the mixing work, and the mixing efficiency is low.

Embodiment 1

[0026] refer to figure 1 and figure 2 , a mixing device for processing pharmaceutical intermediates, comprising a mixing box 1, the top of the mixing box 1 is rotatably connected to a rotating shaft 7, and the top of the rotating shaft 7 is provided with a motor 6, and the outer wall of the middle part of the rotating shaft 7 is equidistantly fixedly connected to four telescopic mechanisms 9 , and the upper and lower outer walls at one end of each telescopic mechanism 9 are hinged with connecting rods 3, and one end of the two connecting rods 3 is hinged with a swing plate 4, and one end of each swing plate 4 is hinged at the outer wall of the rotating shaft 7, and each swing plate 4 The upper and lower outer walls are fixedly connected with a plurality of stirring rods 8. By setting the telescopic mechanism 9, the connecting rod 3, the swing plate 4, and the stirring rod 8, when the pharmaceutical intermediate is mixed and stirred, the telescopic mechanism 9 uses the connect...

Embodiment 2

[0034] refer to image 3 , a mixing device for the processing of pharmaceutical intermediates. Compared with Example 1, two horizontal plates 14 are fixedly connected to the outer walls on both sides of the rotating shaft 7, and the outer walls on the opposite side of the two horizontal plates 14 are fixedly connected to scrapers. Plate 13, by arranging horizontal plate 14 and scraper plate 13, can scrape off the raw material attached to the inner wall of mixing box 1, avoiding the situation that the raw material adheres to the inner wall for a long time and makes it difficult to clean, and facilitates the cleaning work of the staff.

[0035] Working principle: Compared with Embodiment 1, two horizontal plates 14 are fixedly connected to the outer walls on both sides of the rotating shaft 7, and the outer walls on the opposite side of the two horizontal plates 14 are fixedly connected to the scraper plate 13. By setting the horizontal plates 14 and The scraper 13 can scrape of...

Abstract

The invention discloses a mixing device for processing medical intermediates. The mixing device comprises a mixing box, a rotating shaft is rotatably connected to the top of the mixing box, a motor isarranged at the top of the rotating shaft, four telescopic mechanisms are fixedly connected to the outer wall of the middle of the rotating shaft at equal intervals, and connecting rods are hinged tothe outer walls of the upper portion and the lower portion of one end of each telescopic mechanism; swing plates are hinged to one ends of the two connecting rods, one end of each swing plate is hinged to the outer wall of the rotating shaft, and a plurality of stirring rods are fixedly connected to the outer walls of the upper portion and the lower portion of each swing plate. By arranging the telescopic mechanism, the connecting rod, the swing plate and the stirring rod, when medical intermediate raw materials are mixed and stirred, the telescopic mechanism enables the swing plate to swingup and down in a reciprocating mode through the connecting rod, so that the stirring rod can stir various raw materials in the mixing box in a large range, the raw material stirring effect is improved, and therefore the raw materials are mixed more sufficiently, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical processing, in particular to a mixing device for processing pharmaceutical intermediates. Background technique [0002] Pharmaceutical intermediates refer to some chemical raw materials or chemical products used in the process of pharmaceutical synthesis. This kind of chemical product does not require a drug production license, and can be produced in ordinary chemical factories. As long as it reaches a certain level, it can be used in the synthesis of drugs. [0003] When the pharmaceutical intermediate is used or prepared, it needs to be fully mixed before it can be used; in this process, the mixing device is indispensable. Stirring rods for intermediate mixing are often fixed and integrated with the rotating shaft, so that the stirring rods will not move during stirring, so that the raw materials cannot be fully mixed, and it takes a long time to complete the stirring work, and the mixin...
