Description

Technical Field

[0001] The present application relates to the technical field of coating processing, and in particular to an electrophoretic coating emulsifying kettle. Background Art

[0002] The electrophoretic coating emulsification kettle is mainly composed of a reactor body, a stirring system, a feeding system, a temperature control system, a pressure control system, a discharge system, etc. The electrophoretic coating emulsification kettle is mainly used to mix the various components in the electrophoretic coating evenly through an emulsification reaction to form a stable emulsion system. It also forms fine droplets by stirring and emulsifying two or more immiscible liquids, thereby increasing the reaction efficiency and coating quality.

[0003] After searching, the publication number: CN215742919U announced a polymer material coating emulsification kettle, which can more conveniently add solid raw materials into the feeding box through the funnel. After the solid raw materials are added to the feeding box, closing the cover can prevent the raw materials from splashing out from the inside of the feeding box during grinding. The grinding component can grind and crush the solid raw materials inside the feeding box, so that the solid raw materials with larger particles fall into the kettle body after grinding and crushing.

[0004] Regarding the above-mentioned related technologies, the inventors believe that there are the following technical defects that need to be improved: Although this device adds a grinding process, traditional electrophoretic coatings will undergo pre-grinding operations before emulsification to screen the coating to ensure that it meets the standards, and this device only completes a single stirring operation through stirring blades. The gap between the stirring blades is large, which will cause the stirring effect to be reduced, and bubbles will be generated during the stirring process. Traditional technology will add defoaming agents, but the defoaming effect is general. If too much defoaming agent is added, the color uniformity and stability of the coating will be reduced, thereby reducing production quality. Utility Model Content

[0027] The following is combined with Figure 1-4 This application is described in further detail.

[0028] The present application discloses an electrophoretic coating emulsification kettle. Figure 1-4 The electrophoretic paint emulsification kettle includes a high-efficiency emulsification mechanism 1, which includes an emulsification tank body 11, an exhaust pipe 12, a vacuum pump 13, a corrosion-resistant shaft 14, a first stirring rod 15 and a second stirring rod 16. The exhaust pipe 12 passes through the top of the emulsification tank body 11 and fits tightly with the inner surface of the emulsification tank body 11. The input end of the vacuum pump 13 is snapped into the outer side of the exhaust pipe 12. The corrosion-resistant shaft 14 is rotatably connected to the middle of the top of the emulsification tank body 11. The first stirring rod 15 and the second stirring rod 16 are welded to the outer wall of the corrosion-resistant shaft 14. An auxiliary stirring assembly 2 is also provided on the outside of the corrosion-resistant shaft 14.

[0029] The first stirring rods 15 and the second stirring rods 16 are arranged in a plurality of groups, and the plurality of groups of second stirring rods 16 are staggeredly distributed inside the gaps of the first stirring rods 15 to increase the contact area with the electrophoretic coating.

[0030] The auxiliary stirring assembly 2 includes a positioning frame 21, a fixed plate 22, a mixing shaft 23, a sealing cover 24 and a stepper motor 25. The positioning frame 21 is welded and fixed to the outer wall of the corrosion-resistant shaft 14, the fixed plate 22 is fixedly connected to the inner side of the positioning frame 21, the mixing shaft 23 is rotatably connected to the opposite side of the fixed plate 22, the sealing cover 24 is installed at the upper end of the fixed plate 22, and the motor shaft of the stepper motor 25 is fixedly connected to the top of the mixing shaft 23 through a coupling.

[0031] A servo motor 3 is also provided at the upper end of the corrosion-resistant shaft 14 .

[0032] A return pipe 4 and a pneumatic diaphragm pump 5 are also provided at the bottom of the emulsification tank body 11. The input end of the pneumatic diaphragm pump 5 is clamped with one end of the return pipe 4. The return pipe 4 passes through one side of the bottom of the emulsification tank body 11 and fits tightly with the inner wall surface of the emulsification tank body 11.

[0033] The first stirring rod 15 and the second stirring rod 16 are evenly arranged on the outer wall of the corrosion-resistant shaft 14 at an angle of 11° to 18° along the horizontal direction.

[0034] The use process of the electrophoretic coating emulsification kettle in the embodiment of the present application is roughly as follows:

[0035] The electrophoretic coating can be put into the emulsification tank 11 and mixed evenly through the emulsification reaction. During operation, the servo motor 3 on the top is started, and the servo motor 3 drives the corrosion-resistant shaft 14 to rotate, so that the first stirring rod 15 and the second stirring rod 16 on the outside rotate synchronously. Since the first stirring rod 15 and the second stirring rod 16 are staggered and in opposite directions, the opening density of the stirring rods is increased, and the stirring effect is improved. At the same time, the stepper motor 25 inside the sealing cover 24 can be started synchronously, and the stepper motor 25 drives the mixing shaft 23 to rotate. The rotation direction of the mixing shaft 23 is opposite to that of the corrosion-resistant shaft 14, thereby disrupting the directional flow of the internal fluid and improving the uniformity of the mixing; then start the pneumatic diaphragm pump 5, and the pneumatic diaphragm pump 5 will discharge the sedimentation material at the bottom from the return pipe 4 back into the top of the emulsification tank 11 to improve the mixing effect; then start the outer vacuum pump 13, and the bubbles generated during the stirring process will be discharged to the outside of the emulsification tank 11 through the exhaust pipe 12, reducing the generation of bubbles.

[0036] The beneficial technical effects of the electrophoretic coating emulsification kettle of the embodiment of the present application are roughly as follows:

[0037] The first stirring rod 15 and the second stirring rod 16 of the device are inclined rod-shaped structures to increase the contact area with the coating, and the first stirring rod 15 and the second stirring rod 16 are staggered and opened in opposite directions, thereby enhancing the stirring effect; on the other hand, the rotating mixing shaft 23 can disrupt the directional flow of the internal fluid, and the bubbles generated in the process can be extracted by the vacuum pump 13 to improve the product quality. The pneumatic diaphragm pump 5 discharges the sediment material at the bottom from the return pipe 4 back into the top of the emulsification tank 11 to improve the mixing effect.

[0038] The above description is only a preferred embodiment of the present application and is not intended to limit the present application.
