[0022] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Reference will now be made in detail to various embodiments of the present application, examples of which are illustrated in the accompanying drawings and described below. For the purpose of explanation and definition, the terms "upper", "lower", "inner" and "outer" are used to describe the features of the example embodiments shown in the drawings with reference to the positions of the features.

[0024] Figure 1 A schematic view of a drug unloading system according to an embodiment of the present application is shown. As shown in Figure 1 the drug unloading system includes a first valve for transferring drug liquid to a tank truck with a self-contained pump, a quick coupling for connecting the first valve and the tank truck with the self-contained pump, a second valve for transferring drug liquid to a tank truck without a self-contained pump, and a drug unloading pump for providing output pressure for drug liquid transfer via the second valve.

[0025] In the related art, the types of tank trucks for supplying liquid medicine from suppliers are different. Some tank trucks are equipped with unloading pumps, and the factory only needs to be equipped with unloading pipelines. Some tank trucks do not have self-provided pumps, and the factory needs to separately set up unloading pumps and pipelines. The two sets of unloading systems are prone to misconnection, are not convenient to manage, and are prone to cause safety hazards. The embodiment of the present application realizes the use of tank truck supporting pumps or independently set unloading pumps in the same device through integrated construction, and the two working conditions are switched. The tank truck pipeline is connected with the quick connector, and the direction can be installed horizontally or obliquely according to the actual situation. When the first valve is opened and the second valve and the third valve are closed, the tank truck supporting pump is used for pumping. When the second valve is opened and the first valve and the third valve are closed, the unloading pump is used for pumping.

[0026] According to the embodiment of the present application, the unloading system further comprises a medicine storage tank, and the second valve and the unloading pump are further used for transferring the liquid medicine to the medicine storage tank. A monitoring device is used for observing, detecting and controlling the liquid level of the medicine storage tank. The monitoring device specifically comprises a camera located outside the medicine storage tank for observing the liquid level, a liquid level meter located inside the medicine storage tank for detecting the liquid level, and a controller located outside the medicine storage tank for controlling the opening and closing of the unloading pump according to the liquid level. The unloading pump and the monitoring device are automatically connected and interlocked to automatically close according to the liquid level. The automatic closing of the unloading pump according to the liquid level comprises obtaining the current pumping flow rate of the unloading pump, obtaining the change duration of the liquid level after the unloading pump is closed which is pre-stored by the unloading system, determining that the change number of the liquid level after the unloading pump is closed is equal to the product of the current pumping flow rate and the change duration, determining that the early warning liquid level of the monitoring device is equal to the difference between the total liquid level of the medicine storage tank and the product, and closing the unloading pump when the actual liquid level of the medicine storage tank reaches the early warning liquid level. The monitoring device further comprises a display screen for displaying the liquid level of the medicine storage tank.

[0027] In the related art, when the in-plant storage tank is far away from the unloading point or is not easy to observe, it is easy to cause over-dosing, resulting in overflow and running accidents of the liquid medicine storage tank. Even if the unloading pump is closed according to the numerical change of the liquid level meter, the residual liquid medicine in the pipeline may flow into the medicine storage tank, causing overflow accidents. The unloading pump needs to be closed in advance. The embodiment of the present application can observe the liquid level of the liquid medicine storage tank in real time by setting the liquid level meter, the camera and the controller, so as to avoid overflow and running of the storage tank. The controller can conveniently control the unloading pump and observe the liquid level alarm, and can also realize the linkage of the liquid level signal and the unloading pump. Furthermore, by setting the automatic closing method of closing the unloading pump in advance according to the change of the liquid level, the overflow and running accidents caused by the residual liquid medicine in the pipeline are prevented. Thus, the problem of inconvenient observation of long-distance transportation of liquid medicine and easy over-dosing is solved.

[0028] Figure 2 、 Figure 3 The internal arrangement diagram and the internal cross-sectional view of the unloading system according to the embodiment of the present application are shown. As shown inFigure 2 , Figure 3 As shown, the unloading system also includes a waste liquid collection device for collecting waste liquid after the drug transfer is completed. The waste liquid collection device includes: a vent pipe and a third valve thereon, located below and connected to the first and second valves, the diameter of the vent pipe being 1 / 5 of the pipe diameter at the first and second valves; a waste liquid collection funnel, located below the vent pipe, consisting of an inclined baffle and a branch pipe at the bottom of the baffle, the diameter of the branch pipe not exceeding 2 / 3 of the diameter of the vent pipe; and a waste liquid collection bucket located below the waste liquid collection funnel.

[0029] In related technologies, after unloading, residual liquid often spills onto the ground, causing environmental pollution. This invention provides a drug unloading system with an upper and lower layer arrangement and a funnel-shaped baffle design, allowing for the safe collection of residual waste liquid in the pipeline. A movable waste liquid collection tank facilitates convenient and quick recycling and treatment of the waste liquid, solving the problem of spillage and preventing environmental pollution.

[0030] According to an embodiment of the present invention, the waste liquid collection funnel is configured according to the viscosity coefficient of the waste liquid. At room temperature, when the first ratio of the viscosity coefficient of the waste liquid to a predetermined viscosity coefficient threshold is equal to the product of the second ratio of the tilt angle of the partition to a predetermined tilt angle threshold and the third ratio of the branch pipe diameter to a predetermined diameter threshold, and the viscosity coefficient of the waste liquid is greater than the predetermined viscosity coefficient threshold, the tilt angle of the partition exceeds the predetermined tilt angle threshold and the diameter of the branch pipe exceeds the predetermined diameter threshold.

[0031] In related technologies, when the viscosity of the waste liquid is too high, it is difficult to flow out of the funnel, which may cause blockage of the funnel and the lower branch pipe. This invention addresses this issue by adjusting the tilt angle of the funnel and the diameter of the lower branch pipe to vary with the viscosity coefficient of the waste liquid. This allows the waste liquid collection funnel to adapt to different types of pharmaceutical solutions, solving the problem of some waste liquids having excessively high viscosity and being difficult to flow, thus affecting waste liquid collection efficiency.

[0032] Figure 4 , Figure 5 , Figure 6 An external elevation view of a drug unloading system according to an embodiment of the present invention, and an internal sectional view and external elevation view of a drug unloading system for various liquid drugs are shown. Figure 5 , Figure 6 As shown, the unloading system has independent compartments for collecting different types of medicines; the unloading system has independent transparent observation windows and door locks to prevent incorrect connection of medicines; the unloading system adopts a skid-mounted connection.

[0033] In the related art, the same factory often needs multiple different chemical solutions. Different types of chemical solutions are prone to be connected incorrectly and are inconvenient to manage. Embodiments of the present application provide a modularly designed chemical unloading system, which can realize multiple operating conditions through different permutations and combinations. The chemical unloading system is provided with independent partitions, and an independent observation window and a door lock are arranged outside each partition, and a label indicating the unused chemical solution is labeled. Different partitions are provided with independent door locks, and a label indicating the unused chemical solution is labeled. Different partitions are provided with independent door locks, which are managed by relevant personnel, so that the chemical solution cannot be mixed and connected incorrectly, thereby solving the problems in the related art.

[0034] In summary, the problems in the related art include the safety hazards and environmental pollution caused by incorrect chemical unloading, chemical solution spillage, overflow of chemical storage tanks, and the like. The present application provides a chemical unloading system, which can realize timely switching of different operating conditions through the design of valves and pipeline systems. The system is connected in a pry manner, a waste liquid collection barrel is arranged at the lower part of the pry box body, waste liquid can be conveniently transferred and recycled, and the waste liquid will not pollute the environment. An electric control box is arranged on the outside of the pry box body, and a control button of the unloading pump, a monitoring display screen of the chemical storage tank, and a liquid level alarm lamp are matched, which can display the liquid level in the chemical storage tank in real time, control the start and stop of the unloading pump, and avoid chemical solution overflow.
