Detailed Implementation

[0017] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example: Please refer to Figure 1-3This utility model provides a technical solution: a reagent addition device. This solution takes into account that most existing reagents require manual addition during mixing, which is inefficient and requires frequent weighing and measurement, making the work cumbersome and affecting the reagent mixing efficiency. Based on the above, this invention sets up the following technical means.

[0019] Specifically, this device includes at least a mounting bracket 1, a pair of connecting rods 2, a storage box 3, three storage cavities 4, three drive switch assemblies, a discharge rack 5, a discharge pipe 6, a switch door 7, a pair of mounting plates 8, a pair of telescopic push rods 9, a pair of rotating rods 10, a weighing sensor 11, and a controller 12.

[0020] Each of the three drive switch assemblies includes: a combination slot 17, a feeding baffle 18, a connecting plate 19, a switch push rod 20, and a pair of compression springs 21;

[0021] Mounting bracket 1 supports the entire equipment. During use, the equipment is mounted on the mixing device using the fixing clamps on mounting bracket 1. The reagents to be added are injected into the storage chambers 4 opened in the storage tank 3. When reagents need to be added, the equipment is started by operating the controller 12 that matches the equipment. The controller 12 controls the extension of the output end of the telescopic push rod 9 of the corresponding reagent storage chamber 4. The telescopic push rod 9 drives the discharge baffle 18 to move outward in the combination slot 17, opening the lower end of the storage chamber 4 and allowing the reagent to flow into the discharge rack 5 and into the discharge pipe 6. When the discharge baffle 18 moves out, the compression spring 21 is stretched. The added reagent is weighed by the weighing sensor 11 to ensure the accuracy of the addition. When the amount of reagent added is reached, the telescopic push rod 9 retracts, driving the discharge baffle 18 back into the storage chamber 4 to stop the addition. Then, the output end of the switch push rod 20, which is mounted on the mounting plate 8 through the rotating hinge seat 15, is extended. Together with the rotating rod 10, the switch door 7 rotates around the hinge 14 to open, allowing the reagent to be added. This achieves rapid and accurate addition of different reagents.

The connecting plate 19 is installed on the discharge baffle 18. The switch push rod 20 is installed on the rear wall of the storage box 3 and the output end is installed on the connecting plate 19.
