[0042] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] refer to Figure 1-4 A liquid dosing device includes a fixed frame 1, a mixing tank 2, a stirring device 3, an inlet pipe 4, a outlet pipe 5, and a switching assembly 6. The fixed frame 1 supports the overall structure and ensures the stability of the equipment. The mixing tank 2 is mounted on the fixed frame 1 and provides a mixing space for the powder and water. The stirring device 3 is mounted on the mixing tank 2 and can achieve the mixing of the powder and water. The inlet pipe 4 is located at the top of the mixing tank 2 and is connected to an external water source to deliver water from the external source into the mixing tank 2. The outlet pipe 5 is located at the bottom of the mixing tank 2 and is connected to a liquid feeding system to deliver the mixed liquid to the liquid feeding system. The external water source and the liquid feeding system are existing technologies and will not be described in detail here. All components can be connected to the liquid dosing device via control valves, enabling connection and disconnection between the external water source, the liquid feeding system, and the liquid dosing device. This is existing technology and will not be elaborated here. The switching component 6 is located between the inlet pipe 4 and the outlet pipe 5, enabling connection and disconnection between the inlet pipe 4 and the outlet pipe 5. When the inlet pipe 4 and the outlet pipe 5 are connected, and the external water source, the liquid feeding system, and the liquid dosing device are disconnected, the mixture of powder and water can be transported from the bottom to the top of the mixing tank 2, realizing the internal circulation of the liquid in the mixing tank 2, thereby improving the mixing effect of the liquid and the uniformity of the powder and water mixture, ensuring the feeding effect. When the inlet pipe 4 and the outlet pipe 5 are disconnected, the mixing tank 2 can normally receive water and discharge materials.

[0044] In some embodiments, the switching component 6 includes a delivery pump 61, a first three-way pipe 62, a second three-way pipe 63, a first control valve 64, and a second control valve 65. The delivery pump 61 is fixed on the mounting frame 1 and can be a power source for liquid delivery. The first three-way pipe 62 is connected to the inlet pipe 4, the liquid feeding system, and the outlet of the delivery pump 61. The second three-way pipe 63 is connected to the outlet pipe 5, an external water source, and the inlet of the delivery pump 61. The first control valve 64 is located between the inlet pipe 4 and the first three-way pipe 62, and the second control valve 65 is located between the outlet pipe 5 and the second three-way pipe 63.

[0045] Specifically, the switching component 6 controls the start and stop of the delivery pump 61 and the on / off states of the first control valve 64 and the second control valve 65 to switch between multiple operating modes:

[0046] When the second control valve 65 is closed and the first control valve 64 is opened, the delivery pump 61 is started. Water from the external water source flows sequentially through the inlet pipe 4 to the first control valve 64, the first three-way pipe 62, the delivery pump 61, and the second three-way pipe 63, and is finally delivered to the mixing tank 2, realizing the water addition function of the liquid dosing device.

[0047] When the first control valve 64 is closed and the second control valve 65 is opened, the external water source is disconnected from the liquid dosing device, and the liquid feeding system is connected to the liquid dosing device, the delivery pump 61 is started. The mixed medicine in the mixing tank 2 passes through the discharge pipe 5 in sequence through the second control valve 65, the second three-way pipe 63, the delivery pump 61, and the first three-way pipe 62, and is finally delivered to the liquid feeding system.

[0048] When the first control valve 64 and the second control valve 65 are opened simultaneously, and the external water source, liquid feeding system and liquid dosing device are all disconnected, the delivery pump 61 is started. The medicine solution after being stirred and mixed in the stirring tank 2 passes through the discharge pipe 5 in sequence through the second control valve 65, the second three-way pipe 63, the delivery pump 61, the first three-way pipe 62, the first control valve 64, and the liquid inlet pipe 4, and finally returns to the stirring tank 2, realizing the circulation of the medicine solution in the stirring tank 2, and cooperating with the stirring device 3 to realize the repeated mixing of the medicine solution.

[0049] In some embodiments, the system also includes a drain pipe 7 and a switch valve 8. The drain pipe 7 is connected to the discharge pipe 5. The switch valve 8 is located on the drain pipe 7 and can close the first control valve 64 and the second control valve 65, and open the switch valve 8 to discharge the residual liquid in the mixing tank 2.

[0050] In some embodiments, the mixing tank 2 includes a tank body 21, a feeding port 22, and a tank cover plate 23. The tank body 21 is mounted on a fixed frame 1 and can be fixed by bolt assembly. The tank body 21 can be an octagonal stainless steel body with a conical bottom to ensure that the liquid medicine is discharged quickly and completely after mixing to avoid residue. The tank body 21 is equipped with a stirring device 3. The top of the tank body 21 is equipped with a liquid inlet pipe 4, which can be connected to water supplied by an external water source. The top of the tank body 21 is equipped with a discharge pipe 5. The feeding port 22 is located at the top of the tank body 21 and can be a channel for dispensing solid drugs or additives. The tank cover plate 23 is sealed on the feeding port 22 and is detachably connected to the tank body 21. The bottom of the tank cover plate 23 can be equipped with a sealing ring to achieve sealing at the feeding port 22.

[0051] In some embodiments, the mixing tank 2 further includes two fixed groove plates 24, two locking screws 25, two locking nuts 26, a locking plate 27, and two locking grooves 28. The two fixed groove plates 24 are symmetrically arranged on both sides of the feeding port 22. The locking screws 25 are rotatably arranged on the fixed groove plates 24 and can be connected by a rotating shaft. The locking nuts 26 are screwed to the locking screws 25. The locking plate 27 is coaxially arranged on the cylinder cover plate 23, and the locking nuts 26 are pressed onto the locking plate 27. The two locking grooves 28 are symmetrically arranged on both sides of the locking plate 27, and the locking screws 25 are passed through the locking grooves 28.

[0052] In use, rotate the locking screw 25 so that it passes through the locking groove 28, and apply pressure to the locking plate 27 by tightening the locking nut 26, thereby achieving a tight fit between the cylinder cover plate 23 and the cylinder 21. This structure is easy to operate and can effectively prevent liquid leakage.

[0053] In some embodiments, the stirring device 3 includes a stirring motor 31, a stirring rod 32, two first blades 33, and two second blades 34. The stirring motor 31 is located at the top of the stirring tank 2, and the output shaft of the stirring motor 31 extends into the stirring tank 2 to provide power for the stirring operation. A sealing ring may be provided between the output shaft of the stirring motor 31 and the top of the stirring tank 2 to achieve a seal between the output shaft of the stirring motor 31 and the stirring tank 2. The stirring rod 32 is coaxially connected to the output shaft of the stirring motor 31. The stirring rod 32 may be a hollow square rod, and the bottom of the stirring rod 32 is rotatably connected to the bottom wall of the stirring tank 2. The two first blades 33 are symmetrically arranged on the stirring rod 32, and the two second blades 34 are symmetrically arranged on the stirring rod 32. The line connecting the two first blades 33 is perpendicular to the line connecting the two second blades 34. The second blades 34 are located below the first blades 33. The stirring motor 31 drives the stirring rod 32 to rotate, thereby causing the two first blades 33 and the two second blades 34 to rotate as well. Since the line connecting the two first blades 33 is perpendicular to the line connecting the two second blades 34, and the second blades 34 are located below the first blades 33, the medicine liquid forms a double-layer stirring in the stirring tank 2, and cooperates with the polygonal inner wall to increase the turbulence of the medicine liquid in the stirring tank 2, ensuring that the medicine powder and water are fully mixed.

[0054] In some embodiments, the stirring device 3 further includes a fixed base 35, a positioning pin 36, and a rotating sleeve 37. The fixed base 35 is fixed on the inner bottom wall of the stirring cylinder 2. The fixed base 35 can be an inverted groove plate that can be welded to the inner bottom wall of the stirring cylinder 2. The positioning pin 36 is disposed on the fixed base 35 and can be welded to it. The positioning pin 36 passes through the fixed base 35. The rotating sleeve 37 is coaxially disposed at the bottom of the stirring rod 32 and can be welded to it. It also engages with the positioning pin 36 to facilitate the installation of the stirring rod 32 in the stirring cylinder 2 and to limit the radial sway of the stirring rod 32, thereby improving the stability of operation.

[0055] The specific working principle is as follows:

[0056] In practical use, close the second control valve 65, open the first control valve 64, start the delivery pump 61, and disconnect the liquid feeding system from the liquid dosing device. The external water source enters the mixing tank 2 directly through the inlet pipe 4. When the set amount is delivered, the external water source is disconnected from the liquid dosing device, water delivery is stopped, and the delivery pump 61 is turned off.

[0057] Add the set amount of medicine through the feeding port 22, start the stirring motor 31, and the first blade 33 and the second blade 34 form a vertically intersecting stirring force field to ensure uniform mixing of the medicine solution. At the same time, open the first control valve 64 and the second control valve 65, start the delivery pump 61, so that the medicine solution in the stirring tank 2 flows from the discharge pipe 5 to the inlet pipe 4 and into the stirring tank 2, realizing the circulation of the medicine solution in the stirring tank 2, thereby improving the mixing effect of the powder and water, improving the mixing uniformity, and ensuring the feeding effect. After the set stirring time, the liquid feeding system is connected to the liquid dosing device, the first control valve 64 is closed, and the delivery pump 61 delivers the mixed medicine solution to the liquid feeding system.

[0058] After the delivery is completed, the liquid feeding system is disconnected from the liquid dosing device, the second control valve 65 is closed, the delivery pump 61 is turned off, and the switch valve 8 is opened to allow the residual liquid in the mixing tank 2 to be discharged from the drain pipe 7. During this process, an external water source can be connected to the liquid dosing device, and the first control valve 64 can be opened to start the delivery pump 61 and introduce external water into the mixing tank 2 to clean the mixing tank 2.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
