Technical Field

[0001] The utility model relates to the technical field of dilution and preparation tanks, in particular to a western medicine dilution and preparation tank with a feed flow rate regulating function. Background Art

[0002] The dilution tank, also known as the mixing tank, is an indispensable equipment for the manufacture of medicines and pharmaceutical manufacturers. The dilution tank is a device for mixing two liquids with low viscosity. In the pharmaceutical field, it is mainly used for two liquid medicines with low concentrations. Its function is to mix and blend them; or to mix the liquid medicine with a solution with low concentration. Its function is to dilute and stir.

[0003] After searching, it was found that the Chinese utility model patent with authorization publication number CN217909904U discloses a dilution tank with a cleaning device. It can be seen from its specification that when the liquid dilution is completed, the two second rotating motors are turned on to drive the gears connected to them to engage and rotate on the outer wall of the toothed plate ring, which can drive the two telescopic rod sleeves to rotate. At this time, the main telescopic rod is automatically extended, driving the two cleaning brush rods to move downward, and pouring clean water into it from the water inlet pipe, which is conducive to ensuring that the cleaning brush rods rotate and clean the inner wall of the dilution tank body.

[0004] Therefore, the dilution tank in the above patent has the following problems: (1) It does not have heating and heat preservation functions, resulting in low efficiency of dissolving ingredients; (2) It is cleaned by a brush, and dirt or bacteria are easily retained on the surface of the brush, resulting in poor cleaning effect; (3) The size of the stirring plate is small, and when the stirring plate rotates, the range of stirring is small, resulting in uneven stirring.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] See also Figure 1 The top of the outer tank 2 is connected with a fourth pipe 7 and a sixth pipe 26, and the fourth pipe 7 is provided with a throttle valve 8. The medicine liquid can be input into the inner tank 2 through the sixth pipe 26. The fourth pipe 7 is used to transport the diluent to the inner tank 2, and the throttle valve 8 can be used to adjust the flow rate of the diluent to control the liquid flow.

[0029] The upper part of the inner tank 2 is sealed with a partition 9, and a sleeve 10 is rotatably connected to the partition 9. A driving mechanism for driving the sleeve 10 to rotate is provided above the partition 9. Specifically, the driving mechanism includes a motor 14 installed on the partition, a transmission shaft connected to the motor through a coupling, a main gear 15 connected to the transmission shaft, and a sub-gear 16 connected to the sleeve, and the main gear 15 is meshed with the sub-gear 16. When the motor 14 is started, the transmission shaft is driven to rotate. During the rotation of the transmission shaft, the sleeve 10 is driven to rotate through the cooperation of the main gear 15 and the sub-gear 16. The upper end of the sleeve 10 is connected to a fifth pipe 12 through a rotary joint 11. The fifth pipe 12 is used to transport flushing liquid to the sleeve 10. The setting of the rotary joint 11 prevents the fifth pipe 12 from rotating when the sleeve 10 rotates.

[0030] The lower end of the sleeve 10 passes through the partition 9 and is fixedly connected to a stirring rod 13. The stirring rod 13 is connected to a stirring section. The stirring section is peripherally provided with a flushing section. The outer side of the flushing section is close to the side wall of the inner tank 2. The upper end of the inner side of the flushing section is connected to the sleeve 10, and the lower end is connected to the stirring rod 13. The stirring section includes two horizontal bars 17 connected to the stirring rod and two vertical bars 18 connected between the horizontal bars. The horizontal bars 17 and the vertical bars 18 are arranged in a rectangular shape and connected end to end. When the stirring rod 13 rotates, the horizontal bars 17 and the vertical bars 18 rotate together, stirring the area near the center of the inner tank 2. The flushing section includes multiple U-shaped flushing pipes 19 and a number of nozzles 20 connected to the outer periphery of the flushing pipes. The nozzles 20 are arranged toward the side wall of the inner tank 2. The upper ends of the flushing pipes 19 are connected to the sleeve 10, and the lower ends of the flushing pipes 19 are closed and connected to the stirring rod 13. When not flushing, the flushing pipe 19 rotates with the stirring rod 13, also providing stirring, and can stir the area around the inner tank 2, thereby increasing the stirring area and efficiency. When cleaning is required, the flushing liquid enters the sleeve 10 through the fifth pipe 12 and enters the flushing pipe 19, and is sprayed toward the inner tank 2 by the nozzle 20 to flush the inner tank 2.

[0031] The outer tank 1 is equipped with a first thermometer 23 for recording the temperature within the insulation chamber, and the inner tank 2 is equipped with a second thermometer 24 for recording the temperature within the inner tank. The first thermometer 23 monitors the temperature within the insulation chamber, while the second thermometer monitors the temperature of the liquid within the inner tank. Control valves 25 are installed on each of the first, second, third, and fifth pipes 12, controlling the opening and closing of each pipe.

[0032] The working principle of this embodiment is:

[0033] By adding a heated medium to the insulation chamber 3, the inner tank 2 can be heated or insulated, allowing the liquid medicine to dissolve within the desired temperature range and increasing the dissolution rate. When diluting the liquid medicine, the liquid medicine is fed into the inner tank 2 through the sixth pipe 26, and the diluent is delivered to the inner tank 2 through the fourth pipe 7. The flow rate of the diluent is adjusted by the throttle valve 8. The motor 14 is then controlled to rotate the sleeve 10, which in turn rotates the stirring rod 13. The flushing section rotates along with the stirring section, also stirring the liquid medicine. The stirring section stirs the central area of ​​the inner tank, while the flushing section stirs the outer area of ​​the inner tank, increasing the stirring area and efficiency. When the liquid medicine is prepared, it is discharged from the third pipe 6. When the inner tank needs to be cleaned, the control valve on the fifth pipe 12 is opened to allow the flushing liquid to enter the sleeve 10 and be sprayed toward the side wall of the inner tank 2 through the flushing pipe 19 and the nozzle 20 to flush the side wall of the inner tank 2 and wash away the dirt on the inner tank 2. On the one hand, the cleaning work is completed, and on the other hand, no dirt or bacteria will remain on the flushing part, thereby improving the cleaning effect.

[0034] A throttle valve is a valve that controls fluid flow by changing the throttle cross-section or length. A rotary joint connects and rotates pipes. A control valve can be an electric valve. All three are currently available and commercially available, so they will not be described in detail in this embodiment.

[0035] Example 2

[0036] Based on Example 1, the bottom front bracket 21 of the inner tank 2 is provided with a support bracket 21, to which the lower end of the stirring rod 13 is rotatably connected. A sealing ring 22 is provided at the contact point between the partition plate 9 and the sleeve 10. This bracket arrangement improves the stability of the stirring rod during rotation. The sealing ring prevents liquid from entering above the partition plate, thereby protecting the drive mechanism.
