[0036] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0037] Example

[0038] See also Figure 1 to Figure 3 The present embodiment provides an automatic dispensing system, including a chemical barrel 1, a dosing aspirator 2, a weighing device 3, a dispensing barrel 4, a dosing pipe 5, a water supply pipe 6, a liquid level meter 7, an alarm device 8 and a PLC control cabinet 9.

[0039] The chemical barrel 1 adopts a standard size (such as 25 kg). The top of the chemical barrel 1 has an interface.

[0040] The dosing aspirator 2 has an inlet and an outlet; the inlet of the dosing aspirator 2 (such as a centrifugal pump) is detachably connected to the interface. Specifically, the interface has an external thread, and an internal thread used in conjunction with the external thread is provided at the inlet 21 of the dosing aspirator. The inlet 21 of the dosing aspirator is threadedly connected to the interface of the chemical barrel 1, and the two are easy to disassemble and assemble.

[0041] In a specific implementation scenario, the outer diameter of the interface is 56 mm, the inner diameter is 50 mm, and the inner diameter of the inlet 21 of the medicated aspirator is 56 mm.

[0042] The chemical barrel 1 is placed on a weighing device 3 , and the weighing device 3 is used to detect the weight change of the chemical barrel 1 .

[0043] In a specific implementation scenario, the weighing device 3 has a weight display function (display screen 31 ).

[0044] The medicine dispensing barrel 4 is used for dispensing medicine; the medicine dispensing barrel 4 has a medicine adding port 41 , a water inlet 42 and a liquid level detection port 43 .

[0045] One end of the dosing tube 5 is connected to the outlet of the dosing aspirator 2 , and the other end is connected to the dosing port 41 of the dosing barrel 4 .

[0046] In a specific implementation scenario, the dosing tube 5 is a hose, and the outer diameter of the dosing tube 5 is 12 mm.

[0047] The water supply pipe 6 is connected to the water inlet 42 of the medicine dispensing barrel 4; a water supply valve 61 is arranged on the water supply pipe 6. In a specific implementation scenario, the water supply valve 61 is a ball valve.

[0048] The liquid level meter 7 is connected to the liquid level detection port 43 for monitoring the liquid level in the medicine dispensing barrel 4. The liquid level detection port 43 is located on the side wall of the medicine dispensing barrel 4.

[0049] The alarm device 8 is arranged at a designated location on site.

[0050] The PLC control cabinet 9 is arranged at a designated location on site.

[0051] The input end of the PLC control cabinet 9 is electrically connected to the output end of the weighing device 3 and the output end of the liquid level meter 7 , and the output end of the PLC control cabinet 9 is electrically connected to the control end of the water supply valve 61 , the control end of the dosing aspirator 2 and the input end of the alarm device 8 .

[0052] By setting up the above-mentioned weighing equipment 3, liquid level meter 7, PLC control cabinet 9, water replenishment valve 61 and dosing aspirator 2, the automation of the drug dispensing process is realized; specifically, when the liquid level in the drug dispensing barrel 4 is at the preset lower limit value (0.15m), the PLC control cabinet 9 opens the water replenishment valve 61, and closes the water replenishment valve 61 when the liquid level of the drug dispensing barrel 4 is replenished to the appropriate liquid level (0.65m). The PLC control cabinet 9 enables the dosing aspirator 2 to work, and the medicine in the chemical barrel 1 is sucked into the drug dispensing barrel 4 to mix with water. The mass of the medicine to be added to the chemical barrel 1 is calculated according to the setting of the medicine ratio concentration. When the weight change of the chemical barrel 1 reaches the mass of the medicine to be added to the chemical barrel 1, the dosing aspirator 2 stops, thereby completing the drug dispensing process.

[0053] The weighing device 3, liquid level meter 7, PLC control cabinet 9 and alarm device 8 constitute a DCS alarm subsystem; the functions of the DCS alarm subsystem are:

[0054] 1. When the detection value of the liquid level meter 7 reaches the preset upper limit value (0.7m), the alarm is triggered, and the alarm device 8 works to prompt the completion of the drug dispensing by sound, light, etc. At the same time, the drug dosing aspirator 2 stops working.

[0055] 2. When the detected value of the weighing device 3 is lower than the preset weight required for a single dosing, an alarm is triggered, and the alarm device 8 works to warn in the form of sound, light, etc. At this time, manual intervention is required to replace a new chemical barrel 1.

[0056] In combination with the above content, this embodiment has at least the following beneficial effects:

[0057] 1. The dispensing process is highly automated with minimal human intervention, which reduces the risk of drug burns, eye splashes, and hand cuts and scratches.

[0058] 2. The system has an alarm prompt function, which can promptly remind workers that the preparation of medicines is completed or that new chemical barrels need to be replaced 1.

[0059] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be combined with each other at will. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
