[0051] The working process of a combined closed liquid distribution device provided by the present invention will be described below:

[0052] As Figures 1 to 2 shown, for the sake of concise and clear expression, the electromagnetic valves in the device are named, specifically as Figure 2 shown.

[0053] Several combined forms during the operation of the combined closed liquid distribution device are:

[0054] Method 1: When solenoid valve 1, solenoid valve 2, and solenoid valve 3 are opened and the solenoid valves on the remaining pipelines are closed, the liquid flows only into liquid tank 1 through the total liquid inlet (i.e., the top of the liquid inlet pipe of liquid distribution tank 3), and finally flows out through the total liquid outlet (i.e., the end of the liquid outlet pipe of liquid distribution tank 1), realizing single liquid distribution;

[0055] Method 2: When solenoid valve 4, solenoid valve 5, and solenoid valve 6 are opened and the solenoid valves on the remaining pipelines are closed, the liquid flows only into liquid tank 2 through the total liquid inlet, and finally flows out through the total liquid outlet, realizing single liquid distribution;

[0056] Method 3: When solenoid valve 5, solenoid valve 8, and solenoid valve 9 are opened and the solenoid valves on the remaining pipelines are closed, the liquid flows only into liquid tank 3 through the total liquid inlet, and finally flows out through the total liquid outlet, realizing single liquid distribution;

[0057] Method 4: When solenoid valve 1, solenoid valve 2, solenoid valve 4, and solenoid valve 6 are opened and the solenoid valves on the remaining pipelines are closed, the liquid flows into liquid tank 1 and liquid distribution tank 2 in sequence through the total liquid inlet, and finally flows out through the total liquid outlet, that is, realizing two-stage series liquid distribution;

[0058] Method 5: When solenoid valve 1, solenoid valve 2, solenoid valve 8, and solenoid valve 9 are opened and the solenoid valves on the remaining pipelines are closed, the liquid flows into liquid tank 1 and liquid distribution tank 3 in sequence through the total liquid inlet (i.e., the top of the liquid inlet pipe of liquid distribution tank 3), and finally flows out through the total liquid outlet, that is, realizing two-stage series liquid distribution;

[0059] Method 6: When solenoid valve 4, solenoid valve 5, solenoid valve 7, and solenoid valve 8 are opened and the solenoid valves on the remaining pipelines are closed, the liquid flows into liquid tank 2 and liquid distribution tank 3 in sequence through the total liquid inlet (i.e., the top of the liquid inlet pipe of liquid distribution tank 3), and finally flows out through the total liquid outlet, that is, realizing two-stage series liquid distribution;

[0060] Method 7: When solenoid valve 1, solenoid valve 2, solenoid valve 4, solenoid valve 7, and solenoid valve 8 are opened and the solenoid valves on the remaining pipelines are closed, the liquid flows into liquid tank 1, liquid tank 2, and liquid distribution tank 3 in sequence through the total liquid inlet (i.e., the top of the liquid inlet pipe of liquid distribution tank 3), and finally flows out through the total liquid outlet, that is, realizing three-stage series liquid distribution;

[0061] Among them, when the combined closed liquid distribution device performs first-stage or second-stage liquid distribution, the unoperated liquid distribution tank can be repaired or maintained through manhole 20.

[0062] In addition, the working mode of the liquid preparation tank is as follows: materials are added through the chemical dosing port 15, and the motor is started to drive the stirring paddle to rotate, so as to stir the materials in the mixing chamber 11 evenly. The evenly mixed materials are transported to the liquid outlet 141 through the bottom end of the liquid outlet pipe by pump pressure and sent to the next mixing chamber 11. During the whole process, the input amount of the liquid in the mixing chamber 11 can be adjusted accordingly according to the liquid level and pressure displayed by the digital display sensor. After the reaction is completed, the sewage discharge port 19 can be opened for sewage treatment.

[0063] In summary, the present utility model provides a combined airtight liquid preparation device. By connecting several liquid preparation tanks through pipelines and arranging electromagnetic valves on the pipelines, this combined control can not only realize the individual liquid preparation of a single liquid preparation tank, but also realize the liquid preparation in a series multi-stage mode between multiple liquid preparation tanks. In this way, it can meet the requirement that liquid preparation can be carried out simultaneously while repairing the equipment among them. Thus, the continuity of medicine preparation production is greatly improved. By arranging equipment such as a stirring device, a chemical dosing port, a digital display sensor, an air port, an observation port, a sewage discharge port, etc. on the liquid preparation tank, while the liquid preparation tank is in a fully airtight structure state, the operator only needs to perform key operations according to the target preset program to carry out the liquid preparation operation, effectively preventing the contact between the medicine and the outside world, reducing the risk of pollution and ensuring the safety of the operator at the same time. This not only improves the work efficiency, but also reduces the operation difficulty and reduces the human error.

[0064] The above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model.
