[0002] Fine chemicals refer to chemicals with specific functions, small production volumes, and high added value, widely used in pharmaceuticals, pesticides, dyes, coatings, and daily chemicals. The production of these products places extremely high demands on the purity, proportions, reaction conditions, and uniformity of mixing of raw materials. In the liquid mixing process of fine chemicals, it is necessary to ensure precise metering and thorough mixing of all components to achieve the desired chemical and physical properties.

[0003] Chinese Patent CN220508885U discloses a testing device for quantitative analysis of fine chemicals. This patent can precisely control the chemical dosage, avoiding the need for quantitative dosage, which can lead to resource waste if too much is added or failure to detect if too little is added. Through the configuration of a control board, main motor, A-link, B-link, A-stirring shaft, gear ring, and A-gear, the chemical can be stirred evenly, avoiding the possibility of insufficient stirring due to a simple stirring structure. However, in cases where the volume of the liquid cup is not adjustable, the flow control is inaccurate, and the stirring range is not comprehensive, problems such as chemical ratio errors and the existence of mixing dead zones can occur, resulting in poor mixing effect. Therefore, a quantitative stirring device for fine chemicals is provided. Utility Model Content

[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] Please see Figures 1-7 As shown, the purpose of this embodiment is to provide a quantitative stirring device for fine chemicals, including a mixing tank 1. The top of the mixing tank 1 has several liquid inlets 12. A fixed plate 11 is fixedly installed inside the mixing tank 1. Two liquid outlets 13 are symmetrically opened through the fixed plate 11. Each liquid inlet 12 is provided with an adjustable volume liquid cup 2 for measuring chemicals. An adjustment part 3 for adjusting the flow rate is also fixedly installed at the lower end of the liquid cup 2. A stirring part 4 is rotatably installed on the fixed plate 11. A rotating part 5 is rotatably installed on the inner wall of the mixing tank 1. The stirring part 4 and the rotating part 5 are connected to rotate synchronously. A baffle 6 is also fixedly installed on the inner wall of the mixing tank 1.

[0032] The liquid cup 2 includes at least a lower shell 21 and an upper shell 22. The lower shell 21 has a sliding groove 211. The bottom of the upper shell 22 is fixedly connected to a plug ring 23. The plug ring 23 is slidably inserted into the sliding groove 211, and the two are in sealed contact. Two screws 25 are symmetrically threaded through the lower shell 21.

[0033] The insert ring 23 is symmetrically provided with several screw holes 231. According to the chemical ratio and required amount, the upper housing 22 slides to drive the insert ring 23 to slide in the slide groove 211. When the liquid cup 2 is adjusted to a suitable volume, one end of the screw hole 231 passes through the lower housing 21 and is threadedly connected to the corresponding screw hole 231 on the insert ring 23, thereby locking the position of the upper housing 22 and ensuring that the volume of the liquid cup 2 remains unchanged. Then, different chemicals are injected into different liquid cups 2. The outer walls of the lower housing 21 and the upper housing 22 are provided with several scale grooves 26, and the scale grooves 26 are horizontally aligned with the screw holes 231, so that the operator can clearly see the amount of chemicals in the liquid cup 2.

[0034] It should be noted that the number of screw holes 231 on the insert ring 23 in this embodiment is sufficient, and the spacing between adjacent screw holes 231 and the scale represented by adjacent scale grooves 26 are the same, ensuring that when the screw 25 is inserted into the corresponding screw hole 231, the corresponding scale can be used.

[0035] The inner wall of the upper housing 22 is also fixedly connected with a connecting ring 24 to prevent chemical leakage. The length of the connecting ring 24 is greater than the length of the insert ring 23. It effectively covers the gap between the insert ring 23 and the slide groove 211. When the chemical is injected into the liquid cup 2, the connecting ring 24 acts as a barrier to prevent the chemical from leaking into the gap between the insert ring 23 and the slide groove 211. At the same time, the connecting ring 24 also prevents the chemical from leaking into the external environment through the screw hole 231, ensuring the safety of operation and the cleanliness of the environment.

[0036] It should be noted that the lower housing 21 can be directly inserted into the liquid inlet 12. When it is necessary to inject chemicals, the movable block 32 at the bottom of the lower housing 21 can be manually rotated beforehand to align the cylindrical holes 321 of different diameters with the through holes 311. Then the lower housing 21 is inserted into the liquid inlet 12 and the chemicals are injected.

[0037] The adjusting unit 3 includes a fixed block 31 fixedly disposed at the center of the bottom of the lower housing 21. A movable block 32 is disposed below the fixed block 31. The movable block 32 is rotatably mounted on the bottom of the lower housing 21 and has two through holes 311 symmetrically opened through the fixed block 31. Several cylindrical holes 321 of different diameters are symmetrically opened through the movable block 32, and the largest diameter cylindrical hole 321 has the same diameter as the through hole 311. When they are aligned, the chemicals can flow out smoothly. When the smaller cylindrical hole 321 is aligned with the through hole 311, the flow rate of the chemicals will be limited because the flow cross-sectional area is reduced. Conversely, when the larger cylindrical hole 321 is aligned with the through hole 311, the flow rate of the chemicals will increase because the flow cross-sectional area is increased. When a specified amount of chemicals is injected into the liquid container 2, the movable block 32 is rotated so that the through hole 311 covers the solid part of the movable block 32. In this way, the chemicals cannot flow out of the liquid container 2 into the mixing tank 1, thereby avoiding chemical mixing errors caused by misoperation or equipment failure.

[0038] The stirring unit 4 includes a connecting shaft 41 rotatably mounted at the center of the fixed plate 11. Several inclined first blades 42 are fixedly connected to the outer wall of the connecting shaft 41. Several fixing rods 43 are also fixedly connected to the outer wall of the connecting shaft 41. A power source 7 is fixedly installed at the bottom center of the fixed plate 11. The power source 7 is preferably a motor. The output shaft of the motor is fixedly connected to the bottom center of the connecting shaft 41. The connecting shaft 41 passes through the fixed plate 11 and is in sealed contact with it. The motor drives the connecting shaft 41 to rotate, thereby causing the stirring unit 4 to rotate. In order to avoid contamination of the power source 7, limiting plates are symmetrically arranged between the fixed plate 11 and the mixing box 1. The limiting plates are located on both sides of the power source 7 and play a protective role for the power source 7. Therefore, when the chemicals flow through the liquid outlet 13, they will not affect the power source 7.

[0039] The rotating part 5 includes a first ring plate 51, a second ring plate 52 fixedly connected to the outer side of the first ring plate 51, and a plurality of inclined second blades 53 fixedly connected to the inner wall of the first ring plate 51. The second blades 53 are staggered with the first blades 42. This staggered design can break the laminar flow state of the chemicals during the stirring process, promote more thorough mixing and homogenization, and one end of the second blades 53 is toothed, which can generate fine turbulence, which helps to break the agglomeration structure of the chemicals and promote more uniform mixing. One end of the fixing rod 43 is fixedly connected to the inner wall of the first ring plate 51, tightly connecting the rotating part 5 and the stirring part 4 together, ensuring that the rotating part 5 can rotate together with the stirring part 4 to achieve coordinated work.

[0040] The stirring section 4 primarily stirs the chemicals located in the center of the mixing tank 1. While this design can effectively mix the chemicals in the central area, it often struggles to reach the inner wall area of ​​the mixing tank 1, resulting in a relatively low degree of mixing near the inner wall and uneven mixing. However, by setting up a rotating section 5 that rotates synchronously with the stirring section 4, the rotating section 5 is responsible for stirring the area near the inner wall. The two work together to create a comprehensive and uniform mixing environment, ensuring that the chemicals in the mixing tank 1 are fully and evenly mixed.

[0041] The mixing chamber 1 has an annular groove 14. The second annular plate 52 is rotatably installed in the annular groove 14. Both the upper and lower ends of the annular groove 14 are arranged in a circular array with a number of balls 15. The second annular plate 52 is located between the balls 15 at the upper and lower ends, and its outer edge is in close contact with the balls 15. The design of the balls 15 effectively reduces the friction between the second annular plate 52 and the inner wall of the annular groove 14, which not only reduces the resistance during rotation, but also extends the service life of the equipment and reduces energy consumption.

[0042] The baffle 6 includes an inclined plate 61 fixedly installed on the inner wall of the mixing tank 1. The inclined plate 61 is located above the first ring plate 51. A straight plate 62 is fixedly connected to one end of the inclined plate 61. Both the inclined plate 61 and the straight plate 62 are annular structures. By setting the baffle 6, chemicals can be effectively prevented from leaking into the tiny gap between the first ring plate 51 and the inner wall of the mixing tank 1. Furthermore, a gap of 0~1cm is left between the straight plate 62 and the first ring plate 51 to prevent wear on the contact surface of the first ring plate 51 and the straight plate 62 during the rotation of the first ring plate 51. This range ensures sufficient space for the first ring plate 51 to rotate freely while preventing chemical leakage due to excessive gap.

[0043] In practical use, according to the chemical ratio and required amount, the upper housing 22 slides to drive the insert ring 23 to slide in the groove 211 of the lower housing 21, adjusting the volume of the liquid cup 2. After the liquid cup 2 is adjusted to a suitable volume, the screw 25 passes through the lower housing 21 and is threadedly connected to the corresponding screw hole 231 on the insert ring 23, locking the position of the upper housing 22. Different chemicals are injected into the adjusted liquid cup 2 respectively. The scale groove 26 is observed to ensure accurate addition. The rate of chemical injection into the mixing tank 1 is adjusted as needed. The rotation of the movable block 32 is controlled to align the column holes 321 of different diameters with the through holes 311. The power source 7 is started to drive the connecting shaft 41 to rotate, thereby driving the stirring part 4 and the rotating part 5 to rotate synchronously. The first blade 42 of the stirring part 4 stirs the chemicals located in the center of the mixing tank 1, and the second blade 53 of the rotating part 5 stirs the chemicals near the inner wall area. After the chemicals are mixed evenly, the power source 7 is turned off, and the mixed chemicals are discharged from the mixing tank 1 through the liquid outlet 13.

[0044] It should be noted that both sides of the bottom of the mixing tank 1 are equipped with drain holes. The chemicals flowing out through the outlet 13 will be discharged through the drain holes. Pipes can be installed on the drain holes in advance to transport the mixed chemicals to external storage equipment for storage.

[0045] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
