[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

The side of tank 2 is provided with a side cylinder 15, and the top of the side cylinder 15 is provided with a liquid level sensor 13. The inner wall of the solution tank 2 is provided with a through hole 12. The side of the side cylinder 15 away from the solution tank 2 is provided with a control box 6. The bottom surface of motor 7 is provided with a stirring shaft 11, and the bottom surface of motor 8 is provided with a screw 9. The top surface of the solution tank 2 is provided with a feed inlet 16 near the support column 4. The support column 4 is welded to the edge of the base 1. The bracket 3 is N-shaped and is set in the middle of the base 1, and the bracket 3 is bolted to the base 1. Tank 2 is installed in the middle of base 1, and the vertical center axis of solution tank 2 is aligned with that of support 3. Motor 7 is installed on the top surface of support 3 and bolted to support 3. Motor 7 is aligned with the vertical center axis of solution tank 2. A stirring shaft 11 is located inside solution tank 2, with one end extending through the top surface of solution tank 2. The stirring shaft 11 is aligned with the vertical center axis of motor 7 and shaft-connected to motor 7. A collection hopper 10 is installed in the solution tank. The top surface of tank 2 is aligned with the vertical centerline of the hopper 10 and the feed inlet 16. The hopper 10 is bolted to the support column 4. The screw 9 is shaft-connected to the No. 2 motor 8. The side cylinder 15 is integrally formed with the solution tank 2. The through hole 12 is located at the bottom end of the side cylinder 15 and the connection point with the solution tank 2. One end of the liquid level sensor 13 is installed inside the side cylinder 15 and bolted to the side cylinder 15. The control box 6 is located at one end near the side cylinder 15 and bolted to the bracket 3.

[0026] The support column 4 is welded to the middle position near the rear edge of the base 1. The support column 4 is used to fix the second motor 8 and the collection hopper 10. The collection hopper 10 is aligned with the feed inlet 16 on the top surface of the solution tank 2 near the end of the support column 4, and the collection hopper 10 is installed on the feed inlet 16. After installation, it is fixed to the support column 4 with two fixing bolts, so that the collection hopper 10 is fixed on the top of the feed inlet 16. The collection hopper 10 is used to temporarily store the medicine powder. The second motor 8 at the top of the collection hopper 10 is started by the control box 6 and drives the screw 9 to rotate, thereby conveying the medicine powder inside the collection hopper 10 from the feed inlet 16 at the bottom of the collection hopper 10 into the interior of the solution tank 2. The second motor 8 is installed on the top of the support column 4 with four fixing bolts, and the second motor 8 is electrically connected to the control box 6. The bracket 3 is N-shaped and installed in the middle of the base 1 with four fixing bolts. The bracket 3 is used to install the first motor 7 and the control box 6. The control box 6 is installed on the left side of the bracket 3. The first motor 7 is installed in the middle of the top surface of the bracket 3 by six fixing bolts. The first motor 7 is connected to the control box 6 by circuit. The first motor 7 is turned on by the control box 6, so that the first motor 7 drives the bottom stirring shaft 11 to rotate. The rotating stirring shaft 11 mixes and stirs the liquid and powder inside the solution tank 2. The solution tank 2 is installed in the middle of the base 1, and the vertical central axis of the solution tank 2, the bracket 3 and the first motor 7 are aligned. The side cylinder 15 on the left side of the solution tank 2 is used to isolate the liquid inside the side cylinder 15 from the liquid in the solution tank 2. Since the bottom end of the side cylinder 15 is provided with a through hole 12 at the connection between the side cylinder 15 and the solution tank 2, when the liquid enters the solution tank 2, it can also enter the interior of the side cylinder 15 through the through hole 12. The side cylinder 15 will prevent the stirring shaft 11 from affecting the measurement result of the liquid level sensor 13 when stirring inside the solution tank 2.

[0027] In use, water is poured into the solution tank 2 through the inlet 14. The liquid entering the solution tank 2 then flows through the through-hole 12 on the inner wall of the solution tank 2 into the side cylinder 15, making the water level in the side cylinder 15 level with the water level in the solution tank 2. When the float of the level sensor 13 is immersed in the liquid in the side cylinder 15, the buoyancy will cause the float to rise until it is in equilibrium with the liquid surface. The level sensor 13 measures the liquid level by changing the resistance value of the float's position. When the level sensor 13 collects the liquid level, it transmits the data to the control box 6 through the circuit. The control core inside the control box 6... The device receives and processes electrical signals, and starts motor 8 based on the processing results. Motor 8 drives screw 9 to rotate a specified number of times. Screw 9 rotates a specified number of times, and the required proportion of powder in the collection hopper 10 is conveyed into the solution tank 2 through the feed inlet 16. When the powder is added to the liquid, control box 6 controls motor 7 to rotate. Motor 7 drives stirring shaft 11 to rotate. The rotating stirring shaft 11 stirs the liquid and powder in the solution tank 2, thereby completing the automatic mixing of the solution. The mixed solution can be discharged from the drain port 5 on the surface of the solution tank 2. Specific Implementation Example 2:

[0029] Reference Figures 1-6 An automatic solution proportioner in the reaction process of polyaluminum chloride is further based on the basic structure in Specific Embodiment 1. Four limiting frames 17 can be arranged around the solution tank 2, and each of the four limiting frames 17 is fixed to the top surface of the base 1 by two fixing bolts. The solution tank 2 is fixed in the middle position of the base 1 by the four limiting frames 17, so as to prevent the solution tank 2 from shifting off the base 1 due to vibration when the base 1 moves or when the No. 1 motor 7 is stirring, thereby causing damage to the stirring shaft 11 inside the solution tank 2.

[0030] In summary:

[0031] 1. Water is poured into the solution tank 2 through the inlet 14. The liquid entering the solution tank 2 flows into the side cylinder 15 through the through-hole 12 on the inner wall of the solution tank 2, making the water level in the side cylinder 15 level with the water level in the solution tank 2. When the float of the level sensor 13 is immersed in the liquid in the side cylinder 15, the buoyancy will cause the float to rise until it is in equilibrium with the liquid surface. The level sensor 13 measures the liquid level by the position of the float. When the level sensor 13 collects the liquid level, it transmits the data to the control box 6 via an electrical signal. The control chip inside the control box 6 connects to... The electrical signal is processed, and the second motor 8 is started according to the processing result. The second motor 8 drives the screw 9 to rotate a specified number of times. The screw 9 rotates a specified number of times and conveys the required proportion of medicine powder in the collection hopper 10 into the solution tank 2 through the feed port 16. When the medicine powder is added to the liquid, the control box 6 controls the first motor 7 to rotate. The first motor 7 drives the stirring shaft 11 to rotate. The rotating stirring shaft 11 stirs the liquid and medicine powder in the solution tank 2, thereby completing the automatic proportioning of the solution. This solves the problem of not being able to automatically add medicine according to the amount of solution in the solution tank 2.
