Description

Technical Field

[0001] The utility model relates to the technical field of liquid preparation tank devices, in particular to a new type of liquid preparation tank specially used for medicine extraction. Background Art

[0002] It is well known that medical treatment is inseparable from drug treatment, and drug configuration also occupies an important position in drug production. The liquid preparation tank is a mixing and stirring container for mixing one or several materials according to the process ratio. The liquid preparation tank is widely used in the pharmaceutical processing industry. The traditional liquid preparation tank is mainly composed of a tank body and a stirring device. It is necessary to prepare various required stock liquids in a certain proportion and then pour them into the liquid preparation tank for configuration. The raw materials of a certain dynamic ratio are stirred and mixed through the stirring device.

[0003] During the use of the existing new liquid preparation tanks for pharmaceutical extraction, the drug raw materials are usually prepared by workers weighing them. The work intensity is high and the operators are easily fatigued, resulting in a slower weighing speed and reduced accuracy. This not only affects the production efficiency of the drugs, but also causes deviations in the proportion of the prepared raw materials, affecting the stability of the drug efficacy. In addition, since the liquid preparation tank is a closed design, it is inconvenient for the operator to clean the inside of the liquid preparation tank after the drug preparation is completed, resulting in residual drug raw materials in the cylinder. The chemical composition and characteristics of different drugs are different. The residual drug raw materials may react chemically with the next produced drug to produce unknown harmful substances, reducing the safety of drug use. Utility Model Content

[0026] Working principle: In use, when adjusting the raw material ratio, first add the raw material into the batching bin 3 through the injection hopper 51, the weight sensor 6 monitors the weight of the raw material in the batching bin 3 in real time, and the operator observes the weight value of the raw material through the display panel 52. After injecting the required weight, the cylinder 81 starts to retract the piston rod, and the limit block 82 slides upward along the inner side of the slide groove 73, disengaging from the limit on the outer side of the sealing cover 72, and then the sealing cover 72 opens the raw material to flow out and enter the tank body 2 through the set discharge port, thereby improving the accuracy of the mixing ratio. Then the motor 91 starts, driving the rotating shaft 92 to rotate, and at the same time driving the stirring blade 93 to rotate, and the medical raw materials are fully mixed by stirring. When mixing the raw materials, the scraper block 94 scrapes off the raw materials attached to the cylinder wall, which improves the cleanliness of the cylinder while saving raw materials. The mixed liquid medicine is then discharged from the solenoid valve arranged at the bottom of the tank body 2. When the inside of the tank body 2 needs to be cleaned, the water pump 111 is turned on to draw water from the water tank 4 and transport it to the shunt pipe 114 through the delivery pipe 112 connected to the water outlet end. By setting the first rotating joint 10, the delivery pipe 112 enters the inside thereof and does not rotate with the rotating shaft 92. By setting the second rotating joint 113, when the delivery pipe 112 rotates with the rotating shaft 92, the delivery pipe 112 and the shunt pipe 114 are kept in a state of rotational connection, thereby continuously providing water for the nozzle 12. The nozzle 12 is fixed on the top of the scraper block 94. As the scraper block 94 rotates, the tank wall is evenly sprayed, and at the same time, the scraper block 94 scrapes off the residue. The cooperation of the two improves the cleaning effect and ensures that there is no residual raw material inside the tank body 2.
