Description

Technical Field

[0001] The present invention relates to the technical field of solid-liquid mixing, in particular to a solid-liquid agent mixing and stirring device and a mixing method thereof. Background Art

[0002] As a new type of automatic control technology for pharmaceutical mixing that has gradually emerged in recent years, the automatic pharmaceutical mixing and stirring device has gradually become one of the indispensable devices in the fields of water treatment industry, chemical industry and electric power industry. It has obvious advantages over the traditional pharmaceutical mixing and stirring methods. This device can ensure the mixing of medicines in a precise, uniform, accurate, fast and efficient manner, stable operation and easy operation. It greatly reduces and shortens the pharmaceutical mixing time, saves a lot of labor costs, and can effectively solve the problem of micro-precision control in the pharmaceutical mixing and stirring process. At present, the pharmaceutical mixing and stirring devices involved in the existing technology are often single in purpose and can only be applied to the mixing and stirring process of solid pharmaceuticals or liquid pharmaceuticals alone. The overall adaptability on site is poor, the space occupied is large, the control accuracy of the mixing effect machine is not high, and it is easy to cause concentration deviation of the pharmaceutical mixed solution. The main disadvantages are as follows:

[0003] 1. The pharmaceutical mixing and stirring devices involved in the prior art are often single-purpose and can only be applied to the mixing and stirring process of solid pharmaceuticals or liquid pharmaceuticals alone, and have poor overall adaptability on site.

[0004] 2.

[0005] 3. The existing technology involves a lack of a constant temperature control device for the pharmaceutical mixing and stirring device, and the characteristics of the pharmaceutical vary greatly with the seasons.

[0006] 4. The existing technology involves that the pharmaceutical mixing and stirring device often uses a separate stirring impeller to mix the pharmaceuticals, which takes a long mixing time, has poor dissolution (or dilution) effect, and has low preparation accuracy. In particular, the mixing process of some difficult-to-mix and easy-to-sediment pharmaceuticals is not effective.

[0007] 5. Existing solid powder medicine mixing and stirring devices usually use multiple dosing pumps to coordinate the dosing, which has a complex control process and a high failure rate.

[0100] S22, the medicine passes through the pipe B110, the medicine delivery pump 18 and the reflux control valve 13 and re-enters the medicine inhalation device 16 for recirculation;

[0101] S23. After the reagents are completely mixed, when the reagents pass through the reagent delivery pump 18, the reflux control valve 13 is closed and the outlet control valve 14 is opened at the same time, so that the reagents enter the continuous backwash filter 15 for filtration and finally flow out of the mixing device.

[0102] Working mode: The present invention provides a solid-liquid medicine mixing and stirring device and a mixing method thereof. When the present invention is used, solid medicine is added to the solid medicine dosing device 38, and then the second drive motor 382 is energized to automatically discharge the solid medicine dosing device 38. When the solid medicine enters the storage tank 34 through the triangular nozzle 383, the liquid medicine is naturally inhaled through the negative pressure generated by the electromagnetic flowmeter 12 and the dosing control valve 11 passing through the medicine inhalation device 16. At this time, the electromagnetic flowmeter 12 feeds back the flow monitoring signal to the system control device 31 in real time, and the dosing control valve 1 The valve opening can be adjusted in real time to adjust the dosage according to the logic control instructions of the system control device 31. The tube A17 on the medicine inhalation device 16 is at a tangential angle to the storage tank 34. The stirring device 310 of the storage tank 34 is driven by the first drive motor 32 to rotate. The first stirring shaft 311 and the second stirring shaft 313 are two concentric shafts and rotate synchronously in the forward and reverse directions to improve the medicine mixing effect. The lifting height is automatically adjusted according to the feedback logic of the system control device 31 and the liquid level control device 25 to ensure that the first impeller 312 is always placed below the liquid level. The liquid level control device 25 feeds back the liquid level signal to the system control device 31, and adjusts the liquid level in the storage tank 34 to be higher than the first impeller 312 by adjusting the water supply control valve 23, so as to avoid damage to the first drive motor 32 due to the difference in rotational resistance between the first impeller 312 and the second impeller 314. A pressure balancing device 33 is provided on the storage tank 34. The pressure balancing control device 33 is used to balance the internal and external pressures of the storage tank 34 to avoid cavitation or insufficient output of the water pump impeller caused by low inlet pressure of the drug delivery pump 18. A guide plate 37 is also welded on the inner wall of the storage tank 34. The guide plate 37 is at a certain angle to the interior of the storage tank 34, and the center line of the pipe A17 coincides with the center line of the installation height of the guide plate 37. This setting also causes the mixed liquid to form turbulent flow, so that the liquid is further fully integrated. The mixed liquid flows out through the spiral discharging device 39. The spiral discharging device 39 includes a spiral tube 392. The spiral tube 392 can increase the travel path of the liquid and further mix the liquid, thereby achieving a sufficient mixing effect. When the liquid medicine has a temperature requirement, the thermostat 35 can be turned on to control the temperature within the storage tank 34. After the liquid medicine is mixed, it is transported through pipe B, which is equipped with a medicine delivery pump 18, an inlet control valve 19, a reflux control valve 13, an outlet control valve 14, and pipe D112. The inlet control valve 19 is used to block or connect the spiral discharge device 39 at the bottom of the storage tank 34. The medicine delivery pump 18 provides a power source for the medicine addition process and the medicine dissolution and absorption process. The outlet control valve 14 and the reflux control valve 13 can adjust the medicine flow distribution ratio during the medicine addition process and the reflux mixing process according to the system control device 31. Pipe D112 is equipped with a continuous backwash filter 15, which is used to intercept impurity particles contained in the medicine and realize online backwashing operation to prevent impurities from clogging the pipeline. The present invention is simple to operate, has stable performance, a wide range of applications, high accuracy, convenience and practicality, and low cost.
