[0018] An automatic dosing device, a control cabinet 2 and a metering tank 3 are fixedly connected to the top of a supporting bottom plate 1, a drain port 4 is welded to the bottom of the side wall of the metering tank 3, a feed port 6 is arranged on the top of the metering tank 3, a valve body is arranged on the pipeline where the drain port 4 is located, a metering pump 5 is designed on the upper part of the metering tank 3, the metering pump 5 is connected to the preparation liquid pipeline, and the outlet of the metering pump 5 enters the metering tank 3.

[0019] A support frame 9 is welded to the top of the metering tank 3, and a motor 8 is fixedly connected to the top of the support frame 9. A transmission shaft 11 is connected to the output end of the motor 8. The bottom end of the transmission shaft 11 is sleeved in a limit ring 12, and the limit ring 12 is fixed on the inner bottom surface of the metering tank 3. A fixing ring 10 is welded to the surface of the transmission shaft 11, and a cylinder 13 is fixedly connected to the bottom of the fixing ring 10. A connecting ring 14 is fixedly connected to the bottom end of the movable rod of the cylinder 13, and the connecting ring 14 is connected to a stirring rod 15 through a fixing assembly 16. The connecting ring 14 is sleeved on the transmission shaft 11 and can slide up and down along the transmission shaft 11. A connecting rod 17 is fixedly connected to the top of the stirring rod 15, and the connecting rod 17 is fixedly connected to the movable rod of the cylinder 13 at the same time. A fixing sleeve 18 is welded to the end of the stirring rod 15, and the threaded connection of the fixing sleeve 18 is connected to a mounting rod 20, and a cleaning brush 19 is fixedly connected to the surface of the mounting rod 20.

[0020] The motor 8 drives the fixed ring 10 to rotate, and the cylinder 13 connected to the fixed ring 10 rotates accordingly, and the connecting ring 14 connected to the cylinder 13 also rotates, and the stirring rod 15 rotates to drive the liquid to stir. When the cylinder 13 is driven to rotate, it is in an unbalanced state. As the motor starts to reach a certain time, the movable rod of the cylinder 13 drops or rises, so that the motor is in a forward and reverse alternating operation, so that the cylinder 13 is always in an unbalanced state. The cylinder 13 drives the connecting ring 14 to move up and down, and the stirring rod 15 can mix the medicine and water at different heights inside the metering tank 3, thereby improving the mixing effect of the medicine. The stirring rod 15 moves up and down, and the cleaning brush 19 on it can clean the inner wall of the metering tank 3. When the medicine type needs to be changed, no other medicine residues are attached to the inner wall.

[0021] There are four groups of stirring rods 15, connecting rods 17 and cylinders 13, which are evenly distributed in the annular direction, so that the operation is stable.

[0022] The top of the feed port 6 is threadedly connected with a sealing top plate 7, and the feed port 6 is closed after one feeding.

[0023] One implementation of the fixing assembly 16 is: side fixing blocks, bolts, and nuts. The side fixing blocks are fixed on both sides of the stirring rod 15. Screw holes are opened on the side fixing blocks. The bolts penetrate the side fixing blocks and enter the connecting ring 14. The nuts fix the bolts to the side fixing blocks.

[0024] Through the overall intensive setting, the structure is simple and easy to install. Except for the external pipes, these devices are centrally installed on a supporting base plate, integrating the metering tank 3, metering pump 5, and automatic control system. The manufacturer completes the manufacturing, assembly, debugging, and trial operation. The user only needs to place the intelligent full-automatic dosing device in the dosing room, connect the metering pump with the pipeline, the drain port with the pipeline, etc., and send the power supply of the control cabinet 2 and the detection instrument signal to the control cabinet 2 to start and put it into operation. This can greatly reduce the workload of on-site construction, avoid intermediate links, effectively ensure the construction period and project quality, and reduce the trouble and loss of users.

[0025] The use of the automatic dosing device is as follows: open the sealing top plate 7, add the predetermined amount of medicine (soluble powder or granular material, or liquid of original concentration) from the feed port 6, cover the sealing top plate 7 after adding the medicine, calculate the required amount of water or other dissolving liquid according to the added medicine, and add it to the metering tank 3 through the metering pump 5. The stirring rod 15 is driven by the motor 8 to rotate to stir the liquid inside the metering tank 3. After a certain time, the valve of the pipeline where the discharge port 4 is located is opened to allow the liquid to flow into the required tank or pipe tower. The amount of the metering pump is fed back to the control cabinet, and when the required amount is reached, the time relay stirs and mixes according to the preset time. After the time is reached, the control cabinet controls the valve of the pipeline where the discharge port 4 is located to open, and the valve is controlled to close after the liquid is discharged. The dosing device is particularly suitable for drugs that need to be prepared and used immediately. Of course, for prepared liquid drugs, they can be added directly from the metering pump 5, so that the valve of the pipeline where the discharge port 4 is located is open, and the liquid can flow into the required place. The device plays a metering role and has a buffering effect compared to the metering feeding structure directly on the pipeline.
