Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to a medicine powder dissolver. Background Art

[0002] In the pharmaceutical field, it is often necessary to dissolve drug powders for drug testing or subsequent processing. Dissolving drug powders means mixing drug powders with liquids evenly.

[0003] After searching, the patent announcement number CN208465790U discloses a powder dissolver, which belongs to the pharmaceutical field. The technical problem to be solved by the utility model is to provide a powder dissolver with a reasonable structural design that can effectively dissolve powder. The powder dissolver described in the utility model includes a shell, a dissolving chamber is arranged inside the shell, and a fan is arranged outside the shell. The powder is sent into the dissolving chamber by the airflow generated by the fan. A cover body is arranged on the shell, and a nozzle is arranged on the cover body. A water pump supplies water to the nozzle. The liquid sprayed by the nozzle is mixed with the powder sent into the dissolving chamber by the airflow. This scheme makes the powder and the liquid mix evenly, which can effectively avoid the agglomeration of the powder, so that the powder and the liquid are mixed evenly, and the dissolution quality of the powder is improved. A stirring shaft is also arranged on the cover body, and a stirring blade is arranged on the stirring shaft. The stirring shaft is driven to rotate by a motor. This scheme is mainly used to stir the powder and the liquid, so that the powder and the liquid are mixed more evenly.

[0004] When the existing powder dissolver is actually used, when adding powder into the equipment, when the powder is concentrated in a certain area, it is easy to cause excessive powder to form lumps with the liquid. The agglomerated powder will be difficult to dissolve, resulting in low powder dissolution efficiency. For this reason, we propose a powder dissolver to solve the existing problem.

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments. Embodiment 1

[0021] like Figure 1-4 As shown, a medicine powder dissolver proposed by the utility model comprises a second shell 6, a first shell 3 is arranged at the top of the second shell 6, a filter tank 13 is arranged inside the first shell 3, protrusions 15 are installed on the upper sides of the outer walls of the filter tank 13, the other end of the protrusion 15 is installed in the U-shaped groove on the U-shaped card plate 14, a limiting block 27 is installed on the outer wall of one side of the U-shaped card plate 14, the other end of the limiting block 27 is installed in the limiting slot hole 23, a through hole 26 is opened on the surface of the limiting block 27, a limiting column 24 is installed in the through hole 26, and the two ends of the limiting column 24 are respectively installed at the two ends of the hole wall of the limiting slot hole 23, the first shell 3 A first support plate 5 is installed on the outer walls on both sides, and a first reduction motor 4 is installed on the upper surface of the first support plate 5. The output shaft on the first reduction motor 4 is connected to the connecting shaft 31 through a coupling. The other end of the connecting shaft 31 passes through the bearing on the outer wall of the first shell 3 and extends to the inside of the first shell 3 to be connected to the cam 16, and the outer wall of the cam 16 is in contact with the lower surface of the U-shaped card plate 14. The interior of the second shell 6 is provided with a rotating shaft 11, a second spiral blade 28, a stirring rod 20 and a first spiral blade 21, and the second spiral blade 28, the stirring rod 20 and the first spiral blade 21 are sequentially installed on the outer wall of the rotating shaft 11 from left to right.

[0022] The working principle of the powder dissolver based on the first embodiment is: when the staff dissolves the powder, the staff first pours the liquid from the feed pipe 2 into the interior of the second shell 6, and then starts the first reduction motor 4 and the second reduction motor 8. The staff pours the powder from the feed pipe 2 into the filter tank body 13. The start of the first reduction motor 4 will drive the cam 16 to rotate. The rotation of the cam 16 will cause reciprocating extrusion on the U-shaped card plate 14. After the reciprocating extrusion of the U-shaped card plate 14, the filter tank body 13 vibrates up and down in the Y-axis direction. When the filter tank body 13 vibrates up and down in the Y-axis direction, the powder in the filter tank body 13 can be vibrated and screened. The screened powder is filtered from the filter hole 12 and falls into the interior of the second shell 6, so that the powder falls into the filter tank body 13 more evenly. Inside the second shell 6, the situation that the powder is concentrated in a certain area or falls too much into the second shell 6 is avoided. When the second reduction motor 8 is started, it will drive the second spiral blade 28, the stirring rod 20 and the first spiral blade 21 on the outer wall of the rotating shaft 11 to rotate. Because the spiral direction of the second spiral blade 28 is opposite to the spiral direction of the first spiral blade 21, the second spiral blade 28 can transport the liquid to the left, and the first spiral blade 21 can transport the liquid to the right, so that the fluidity of the liquid is increased, and a certain amount of turbulent collision is generated between the liquids. The stirring rod 20 mixes and stirs the powder and the liquid, so that the utility model effectively improves the effect of mixing and dissolving the powder and the liquid, and avoids the occurrence of caking during the mixing and dissolving of the powder and the liquid.
