[0002] As a surface treatment technology widely used in industrial production, electrophoretic coating plays a key role in improving product appearance quality and protection performance.

[0003] During the electrophoretic coating operation, the purity of the electrophoretic paint is extremely susceptible to pollution and reduction. Since the coating environment is not completely clean, small metal debris, dust and other impurities on the surface of the parts will inevitably mix into the electrophoretic paint. As the coating process continues, these impurities continue to accumulate, like sand mixed into pure paint, severely damaging the purity of the electrophoretic paint. If the electrophoretic paint is not recycled and directly recycled, the impurities will adhere to the surface of the new parts along with the paint, causing the surface of the parts to have defects and not be smooth and flat, greatly reducing the quality and appearance of the paint layer and failing to meet the production requirements of high-quality products. Therefore, how to effectively recover electrophoretic paint raw materials is a problem worth discussing. SUMMARY

[0026] It should be noted that the left, right, up, down, front, back and other orientation terms in the embodiments of the present application are only relative concepts or are with reference to the normal use state of the product, that is, the reference of the running direction of the product, and should not be considered as limiting.

[0028] Referring to Figs. 1-3 An electrophoretic paint raw material recycling device for electrophoretic coating, comprising:

[0029] A raw material storage barrel 100 for storing and discharging electrophoretic paint raw materials;

[0030] A support frame arranged at the bottom of the raw material storage barrel 100, the support frame being used to support the raw material storage barrel 100;

[0031] A reagent adding mechanism 200 comprising a flocculant adding assembly, a coagulant aid adding assembly, and an acid-base balancing agent adding assembly, the reagent adding mechanism 200 being arranged on the raw material storage barrel 100 and used to add reagents in the raw material storage barrel 100.

[0032] Specifically, the flocculant adding assembly sends flocculants into the raw material storage barrel 100 to make paint liquid particles gather into flocs. The coagulant aid adding assembly adds coagulant aids to enhance the flocculation effect and accelerate precipitation. The acid-base balancing agent adding assembly has a pH sensor to monitor the acidity and alkalinity in the barrel.

[0033] The flocculant adding assembly, the coagulant aid adding assembly, and the acid-base balancing agent adding assembly each comprise a reagent storage barrel 210, a feeding pipe 220, and a material pumping pump 230, the storage barrels being fixedly arranged on the L-shaped support rod 350, the feeding pipe 220 being arranged in the reagent storage barrel 210, and the material pumping pump 230 being arranged on the feeding pipe 220, the material pumping pump 230 being used to pump the reagents to be added from the reagent storage barrel 210 into the raw material storage barrel 100.

[0034] The acid-base balancing agent adding assembly further comprises a pH sensor arranged in the barrel of the raw material storage barrel 100, a main controller arranged on the barrel wall of the raw material storage barrel 100, the pH sensor being coupled to the main controller, and the main controller being coupled to the material pumping pump in the acid-base balancing agent adding assembly.

[0035] Specifically, in the acid-base balancing agent adding assembly of the electrophoretic paint raw material recycling device, a PH value sensor is arranged in the raw material storage barrel 100 to monitor the acid-base degree of the solution in real time and convert it into an electric signal. A main controller on the barrel wall is connected with the PH value sensor to receive the acid-base degree data transmitted by the PH value sensor. The main controller is pre-set with an acid-base degree range, and compares the received data with the pre-set range. If the acid-base degree of the solution deviates from the pre-set range, the main controller calculates the required amount of acid-base balancing agent according to the deviation, and then sends a control instruction to the pumping pump in the acid-base balancing agent adding assembly. The pumping pump extracts the required amount of acid-base balancing agent from the reagent storage barrel 210 and delivers it to the raw material storage barrel 100, so as to accurately adjust the acid-base degree of the solution, ensure the efficient and stable chemical reaction in the recycling process, and improve the quality and purity of the recycled raw material, thereby creating good conditions for subsequent utilization.

[0036] The stirring mechanism 300 is further arranged to stir the electrophoretic paint after the reagent is added.

[0037] The stirring mechanism 300 comprises an L-shaped support rod 350, a driving mechanism and stirring assemblies, the L-shaped support rod 350 is arranged on the raw material storage barrel 100, the driving mechanism comprises a driving motor 340, a double-headed electric push rod 330 and two groups of stirring assemblies, the driving motor 340 is arranged on the L-shaped support rod 350, the driving motor 340 is used to drive the stirring assemblies to rotate, the double-headed electric push rod 330 is arranged on the output shaft of the driving motor 340, and the stirring assemblies are arranged on the double-headed electric push rod 330.

[0038] The stirring assemblies comprise symmetrical stirring rods 310 and symmetrical connecting rods 320, the stirring rods 310 are respectively rotationally arranged at the ends of the double-headed electric push rod 330, one end of each connecting rod 320 is rotationally connected with the corresponding stirring rod 310, and the other end of each connecting rod 320 is rotationally connected with one of the telescopic rods of the double-headed electric push rod 330.

[0039] Specifically, the driving motor 340 in the stirring mechanism 300 rotates to drive the double-headed electric push rod 330 to rotate. During the rotation of the double-headed electric push rod 330, the telescopic rods reciprocate, the telescopic rods drive the stirring rods 310 to reciprocate in the raw material storage barrel 100 through the connecting rods 320, the stirring rods 310 reciprocate while rotating around the raw material storage barrel 100, and the electrophoretic paint to which the reagent is added is strongly stirred at different positions and angles, so that the reagent and the electrophoretic paint can be uniformly mixed in a short time, and the flocculation reaction can be accelerated.

[0040] The bottom of the raw material storage barrel 100 is provided with a discharge valve 400.

[0041] In summary, the implementation principle of the utility model is as follows:

[0042] When the electrophoretic paint raw material needs to be recycled, the device is first started. The flocculant adding assembly, the coagulant adding assembly and the acid-base balancing agent adding assembly start to work. In the respective reagent storage barrels 210, the pumping pumps are started according to the set program, and the flocculant, the coagulant and the acid-base balancing agent are respectively pumped and transported into the raw material storage barrel 100 through the feeding pipes 220. Among them, the pH value sensor in the acid-base balancing agent adding assembly monitors the acidity and alkalinity of the solution in the raw material storage barrel 100 in real time, and transmits the data to the main controller. The main controller compares and analyzes the received pH value data with the preset standard acidity and alkalinity range, and then accurately controls the amount of acid-base balancing agent added, so as to ensure that the solution is in an acid-base environment suitable for flocculation and precipitation reaction.

[0043] At the same time, the driving motor 340 in the stirring mechanism 300 operates to drive the double-head electric push rod 330 to rotate. During the rotation of the double-head electric push rod 330, the telescopic rod reciprocates, and the telescopic rod drives the stirring rod 310 to reciprocate in the raw material storage barrel 100 through the connecting rod 320. The stirring rod 310 reciprocates while rotating around the raw material storage barrel 100, and strongly stirs the electrophoretic paint to which the reagents are added at different positions and angles, so that the reagents and the electrophoretic paint can be uniformly mixed in a short time and the flocculation reaction can be accelerated.

[0044] After the flocculant, the coagulant and the electrophoretic paint are fully mixed and the flocculation reaction occurs, the impurities and part of the components in the paint gradually gather to form a precipitate. After a period of stirring and reaction, the stirring is stopped and the solution is allowed to stand and precipitate. At this time, due to the precipitation, the substances in the raw material storage barrel 100 are divided into two layers, the upper layer is the relatively useless part containing impurities and solvents, and the lower layer is the main electrophoretic paint precipitate recovered. Then, the lower layer precipitate is discharged through the discharge valve 400 for further subsequent treatment, such as cleaning, drying, re-dispensing, etc., so that it can be used again as the electrophoretic paint raw material and put into the electrophoretic coating process for recycling, thereby realizing efficient recycling of the electrophoretic paint raw material, reducing resource waste and reducing production cost, and being also beneficial to environmental protection.

[0045] The above disclosure is only a specific embodiment of the present application, but the present application is not limited thereto, and any changes that can be thought of by those skilled in the art shall fall within the protection scope of the present application.
