"; but the fly in the ointment is: the diaphragm in the middle of the tank is easily broken due to repeated expansion and contraction during use, and it is not easy to detect after breaking, resulting in the connection between the upper and lower chambers, which will pollute the product and pose a great hidden danger to the quality and safety of the drug.

Embodiment 1

[0016] This embodiment is composed of tank body 27, tank cover 25, liquid medicine input assembly, pressure balance assembly, liquid outlet pipe 28, pressure sensor 21, pressure gauge 23, liquid level gauge 16 and data receiving and processing device 30 and online cleaning and disinfection Input component composition.

[0017] The edge of the end face of the tank body 27 and the tank cover 25 is provided with a flange 1, and the two are connected into a closed container through the flange 1 (with a sealing ring therebetween), and the pressure sensor 21, the pressure gauge 23 and the liquid level gauge The contact of 16 stretches in the inner cavity of this closed container by tank cover 25, and liquid outlet pipe 28 communicates with the lower end of this closed container inner cavity.

[0018] The liquid medicine input assembly includes the liquid medicine input pipe 20, the liquid medicine input valve 17 (can adopt the valve that accords with sanitary conditions, and can be ...

Embodiment 2

[0029] This embodiment is composed of tank body 27, tank cover 25, liquid medicine input assembly, pressure balance assembly, liquid outlet pipe 28, pressure sensor 21, pressure gauge 23, liquid level gauge 16 and data receiving and processing device 30 and online cleaning and disinfection Input component composition. The input valves used in this example are valves that meet sanitary conditions and cannot be automatically opened and closed, such as pneumatic diaphragm valves, etc. Therefore, they all need to be matched with corresponding control solenoid valves to implement linkage. At this time, the gas and liquid valves Combined with the control solenoid valve, it is equivalent to the "gas and liquid valve" in the first embodiment, and its data control line is connected to the control solenoid valve, as follows:

[0030] The edge of the end face of the tank body 27 and the tank cover 25 is provided with a flange 1, and the two are connected into a closed container through t...

Embodiment 3

[0042]This embodiment is basically the same as Embodiment 1, the difference is that the gas discharge valve 9 in the decompression device adopts a proportional adjustment electric diaphragm valve, since the valve can control the opening diameter of the valve according to the data of the system, the control is more precise, Therefore, the throttle valve 3 is canceled, and the output end of the gas discharge valve 9 is no longer connected to the discharge port via the throttle valve 3, but is directly connected to the discharge port.

[0043] Its use process is identical with embodiment one.

Abstract

The invention discloses a pressure balancing tank capable of realizing online cleaning and sterilization, relating to the technical field of pharmaceutical machinery. The pressure balancing tank is composed of a tank body 27, a tank cover 25, a liquid medicine input component, a pressure balancing component, a liquid outlet pipe 28, a pressure sensor 21, a pressure gauge 23, a liquid level meter 16, a data receiving and processing device 30 and an online cleaning and sterilization input component. The pressure balancing tank has the characteristics of simple structure, convenience in pressureadjustment, stable pressure of liquid medicine and the like, can meet the requirements of liquid medicine filling and realize online cleaning and sterilization, and can be used for conveying liquid medicine of large-volume infusion packages in the pharmaceutical industry and can also be used for conveying liquid raw materials in packages of other industries.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical machinery and is used for constant pressure packaging of liquid medicines, in particular to a pressure balance tank capable of cleaning and disinfecting on-line. Background technique [0002] At present, the filling speed of liquid medicine is relatively high, which requires the delivery of the filled medicine to be both fast and accurate. This pressure remains somewhat constant. In the prior art, the delivery of the liquid medicine basically uses a delivery pump or places the liquid medicine tank at a higher position to generate a constant pressure to achieve the purpose of delivery. The pump is used to transport liquid medicine. Although the pressure can reach a high level, it is affected by many aspects such as grid voltage, current, resistance, air bubbles, and filling volume changes, resulting in large pressure fluctuations and low filling accuracy. . By placing the liquid medicine ...
