[0002] In various fields such as fine chemicals, pharmaceutical production, and water treatment, quantitative reagent mixing is a crucial step in ensuring product quality and reaction efficiency. Reagent mixing typically involves two or more liquid raw materials, which are separately metered according to a set ratio and then fed into a mixing tank for uniform mixing before proceeding to the next process or packaging stage. However, most commercially available quantitative reagent mixing devices use different raw material tanks to introduce raw materials into a set of mixing tanks, followed by direct dispensing for mixing. Once a certain type of raw material is depleted, the equipment must be stopped, the original tank replaced, or a wait for refilling required, which affects the efficiency and continuity of the entire mixing process. Therefore, there is an urgent need for a quantitative reagent mixing device that addresses these technical shortcomings. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides an embodiment of a drug quantitative proportioning device, comprising a fixed plate 12 and a mixing tank 7. The mixing tank 7 is fixedly connected to the top of the fixed plate 12. Inlets 10 are opened on both sides of the top of the mixing tank 7. Class I drug storage tank 5 and Class II drug storage tank 8 are respectively arranged on the upper sides of the mixing tank 7. Metering valves 6 are installed between the mixing tank 7 and the Class I drug storage tank 5 and Class II drug storage tank 8. A first Class I drug source tank 1 and a second Class I drug source tank 23 are arranged on the left side of the mixing tank 7. On the right side of the material tank 7, there are Class II first raw material tank 11 and Class II second raw material tank 13. Class I first raw material tank 1 and Class I second raw material tank 23 are each equipped with a Class I material pump 2 at the top. Class II first raw material tank 11 and Class II second raw material tank 13 are each equipped with a Class II material pump 9 at the top. The pumps are connected to the storage tanks by a feeding pipe 3. Class I first raw material tank 1 and Class I second raw material tank 23 are of the same specifications. The feeding pipe 3 uses a pipe of specifications that matches Class I and Class II materials.

[0023] Specifically, such as Figure 1 and Figure 3 As shown, both the Class I drug pump 2 and the Class II drug pump 9 are electric pumps. When the pump receives a control signal, the impeller rotates to create a negative pressure in the pump chamber, which can draw the drug from the original tank and transport it through the feeding pipe 3 to the corresponding Class I drug storage tank 5 and Class II drug storage tank 8. During continuous feeding, even if the drug in one set of original tanks is used up, the other set of original tanks can continue to draw the drug without affecting the operation of the device. There will be no downtime waiting during the production process. The metering valve 6 can accurately control the volume of the drug fed into the mixing tank 7 each time according to the set ratio.

[0024] A bevel gear set 25 is installed on the left side of the outer wall of the mixing tank 7, and a spur gear set 14 is installed on the right side of the outer wall of the mixing tank 7. A drive motor 4 is fixedly connected to the left front end of the outer wall of the mixing tank 7. The output shaft of the drive motor 4 is fixedly connected to the bevel gear set 25. Two sets of stirring rods 24 are installed inside the mixing tank 7. The left side of one set of stirring rods 24 is fixedly connected to the bevel gear set 25, and the right side of both sets of stirring rods 24 is fixedly connected to the spur gear set 14. Four sets of discharge ports 15 are provided at the bottom of the mixing tank 7. A tap 16 is installed at the bottom of each discharge port 15. The taps 16 are evenly distributed.

[0025] Specifically, such as Figure 1 and Figure 2 As shown, the drive motor 4 rotates and outputs torque through the bevel gear set 25, driving a set of stirring rods 24 in the mixing tank 7 to rotate. The spur gear set 14 can synchronously drive another set of stirring rods 24 to achieve bidirectional linkage stirring. When the medicine is sent into the mixing tank 7 through the metering valve 6, it is mixed by the two sets of stirring rods 24 at high speed to ensure that the two different medicines are fully blended. The mixed medicine is discharged through the discharge port 15 and simultaneously distributed into multiple medicine bottles 22.

[0026] Below the mixing tank 7, there is a lifting seat 21. Slider 17 is fixedly connected to both sides of the lifting seat 21. Wall grooves 18 are opened on both sides of the inner wall of the device. The two sets of sliders 17 are respectively embedded in the wall grooves 18 and move. A hydraulic cylinder 20 is fixedly connected to the bottom of the lifting seat 21. A set of sleeves 19 is set on each side of the hydraulic cylinder 20. Four sets of medicine bottles 22 are placed at equal intervals on the top of the lifting seat 21. Each set of medicine bottles 22 corresponds to a set of faucets 16.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, the hydraulic cylinder 20 drives the piston to move by changing the pressure of the internal hydraulic oil chamber, which in turn drives the lifting seat 21 to move up and down. The lifting seat 21 is connected to two sides of the slider 17, which is embedded in the wall groove 18 to limit the left and right displacement of the lifting seat 21 during the lifting process. The hydraulic cylinder 20 raises the lifting seat 21 so that the top of the medicine bottle 22 is close to the corresponding tap 16, reducing the air contact time of the mixed medicine falling from the outlet 15 to the medicine bottle 22.

[0028] Working principle: When Class I agent pump 2 and Class II agent pump 9 receive control signals, the impellers rotate, creating negative pressure in the pump chamber. This draws the agent from the original tank and delivers it through the feeding pipe 3 to the corresponding Class I agent storage tank 5 and Class II agent storage tank 8. During continuous feeding, even if one set of original tanks runs out of agent, the other set can continue to draw agent without affecting the operation of the device. The metering valve 6 can precisely control the volume of agent fed into the mixing tank 7 each time according to the set ratio. The drive motor 4 rotates and outputs torque through the bevel gear set 25, driving a set of stirring rods 24 in the mixing tank 7 to rotate. The spur gear set 14 can synchronously drive the stirring rods 24 to achieve bidirectional linkage stirring. When the medicine is fed into the mixing tank 7 through the metering valve 6, it is mixed by two sets of stirring rods 24 at high speed to ensure that the two different medicines are fully blended. The mixed medicine is discharged through the discharge port 15 and distributed into multiple medicine bottles 22. The hydraulic cylinder 20 drives the piston to move by the pressure change of the internal hydraulic oil chamber, which drives the lifting seat 21 to move up and down. The lifting seat 21 is connected to two sides of the slider 17, which is embedded in the wall groove 18 to limit the left and right deviation of the lifting seat 21 during the lifting process. The hydraulic cylinder 20 raises the lifting seat 21 so that the top of the medicine bottle 22 is close to the corresponding tap 16, reducing the air contact time of the mixed medicine falling from the discharge port 15 to the medicine bottle 22.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
