[0023] Example 1
[0024] Reference Figure 1 A preferred embodiment of the utility model is a dissolution device for detecting rosuvastatin, comprising a heating box 1, a dissolution box 2 is arranged in the heating box 1, a detachable box cover 4 is arranged on the heating box 1, a feeding port 16 connected to the dissolution box 2 is arranged on the box cover 4, a screen 25 is arranged in the feeding port 16, a feed screening bin 6 is arranged on the feeding port 16, a circulating extrusion mechanism is arranged in the feed screening bin 6, and the circulating extrusion mechanism comprises a cam 14 and an operating rod 11, a crushing tooth plate 9 is arranged at one end of the operating rod 11, a spring 10 is arranged on the outer ring of the operating rod 11, and the two ends of the spring 10 are respectively connected to the crushing tooth plate 9 and the inner wall of the feed screening bin 6, and the other end of the operating rod 11 is provided with an abutting slide plate 12, and the abutting slide plate 12 abuts against the cam 14.
[0025] Furthermore, a water tank 5 is provided on the box cover 4 , and the water tank 5 is located on both sides of the feed screening bin 6 . A water inlet pipe 15 is provided on the water tank 5 , and the water inlet pipe 15 passes through the box cover 4 and is connected with the dissolution box 2 .
[0026] A driving motor is disposed outside the water tank 5 , and an output end of the driving motor is connected to a camshaft 13 , and the camshaft 13 is connected to the cam 14 .
[0027] The feed screening bin 6 is provided with a feed port 7 , and the crushing tooth plate 9 is provided with crushing teeth 8 .
[0028] Specifically, when in use, rosuvastatin is introduced into the feed screening bin 6 through the feed port 7, and the driving motor outside the water tank 5 is started. The cam shaft 13 is driven to rotate by the driving motor, thereby driving the cam 14 to rotate. The cam 14 pushes the contact slide plate 12 to move in the horizontal direction, thereby driving the operating rod 11 to move. The operating rod 11 drives the crushing tooth plate 9 to move. When the crushing tooth plate 9 on the left moves to the right, the spring 10 will be stretched. As the cam 14 rotates, the spring 10 will gradually reset. Therefore, under the setting of the cam 14 and the spring 10, the cyclic reciprocating motion of the crushing tooth plate 9 in the horizontal direction can be achieved. Circulating extrusion mechanisms are provided on both sides of the feed screening bin 6, so It can drive the crushing tooth plates 9 on the left and right sides to perform relative cyclic reciprocating motion, thereby realizing the extrusion and crushing of rosuvastatin. The crushed rosuvastatin is screened out through the screen 25 to obtain rosuvastatin of a size matching the screen aperture, so that the rosuvastatin transferred from the feed screening bin 6 to the dissolution box 2 will not exceed a fixed size of material, so that the working environment of the long stirring blade 18 and the short stirring blade 17 in the dissolution box 2 is to stir the drug particles of the same size, reducing the wear of the long stirring blade 18 and the short stirring blade 17, so that the long stirring blade 18 and the short stirring blade 17 will not affect the stirring effect when used for a long time, thereby improving the dissolution efficiency in the dissolution box 2.
[0029] Example 2
[0030] A heating chamber is formed between the heating box 1 and the dissolving box 2, and a heating component is arranged in the heating chamber. A liquid inlet pipe 3 and a drain pipe 24 are arranged on the heating chamber. Electric valves are arranged on the liquid inlet pipe 3 and the drain pipe 24. The heating component includes an electric heating plate 19 and a temperature sensor 20 arranged in the heating chamber. The electric heating plate 19 and the temperature sensor 20 are electrically connected to an external controller.

When the water temperature reaches the preset maximum value, the signal is transmitted to the external controller to control the electric heating plate 19 to stop heating, thereby avoiding the destruction of the medicinal properties of the drug due to excessive water temperature and affecting the later test results. The dissolution box 2 improves the dissolution rate and effect of rosuvastatin by heating the water bath in the heating chamber.

A discharge pipe 21 is provided at the bottom of the dissolving box 2 (preferably, a guide platform is provided at the bottom of the dissolving box 2), and the discharge pipe 21 extends out of the heating box 1 and is provided with an electric valve.
[0034] Specifically, during use, when rosuvastatin material enters the dissolution box 2, the water in the water tank 5 flows into the dissolution box 2 through the water inlet pipe 15, and the motor 23 drives the rotating shaft 22 to rotate, thereby driving the long stirring blade 18 and the short stirring blade 17 to stir, so that the rosuvastatin is dissolved more evenly and heated more evenly.
[0035] To sum up, when the utility model is in use, the dissolution box 2 is heated in a water bath by the heating component to improve the dissolution efficiency of the dissolution box 2, and the size of the material entering the dissolution box 2 is fixed by the setting of the screen 25, and then the motor 23 drives the rotating shaft 22 to rotate, and the rotating shaft 22 drives the staggered long stirring blades 18 and the short stirring blades 17 to stir, so that the rosuvastatin is stirred more evenly and heated more evenly, thereby further improving the dissolution efficiency; and because the working environment of the long stirring blades 18 and the short stirring blades 17 in the dissolution box 2 is to stir the drug particles of the same size, the wear of the long stirring blades 18 and the short stirring blades 17 is reduced, so that the long stirring blades 18 and the short stirring blades 17 will not affect the stirring effect when used for a long time, thereby improving the dissolution efficiency in the dissolution box 2.
[0036] Under the premise that no conflict occurs, those skilled in the art may freely combine and superimpose the above-mentioned additional technical features.
