[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 and Figure 4 The utility model provides an embodiment: a storage tank for preventing sedimentation in coating production, comprising a storage tank 1, a servo motor 3 fixedly connected to the bottom of the storage tank 1, an output end of the servo motor 3 passes through the storage tank 1 and is fixedly connected to an auger 4, a mixing drum 6 is fixedly connected to the middle part of the inner side of the storage tank 1, a discharge port 7 is provided on the left and right sides of the mixing drum 6, the top of the auger 4 passes through the mixing drum 6 and is fixedly connected to a horizontal plate 5, scrapers 8 are fixedly connected to the left and right sides of the bottom of the horizontal plate 5, a heating mechanism 2 is provided on the top of the storage tank 1, and the heating mechanism 2 is used to heat the material;

[0032] Specifically, when the servo motor 3 is started, its output end drives the auger 4 to rotate, and the auger 4 rotates inside the storage tank 1. The rotation of the auger 4 will generate an upward thrust on the paint in the storage tank 1, so that the paint circulates up and down in the storage tank 1. During the flow of the paint, the solid particle precipitation phenomenon caused by long-term standing is avoided. The discharge port 7 opened on the left and right sides of the mixing drum 6 will cause the paint to flow out from different directions during the rotation, further enhancing the fluidity and mixing effect of the paint. The horizontal plate 5 on the top of the auger 4 and the scrapers 8 on the left and right sides of the bottom also rotate synchronously when the auger 4 rotates. During the rotation, the scraper 8 continuously scrapes the inner wall of the storage tank 1 to prevent the solid particles in the paint from adhering to the tank wall and forming precipitation.

[0033] Reference Figure 3 and Figure 2 The heating mechanism 2 includes a cover plate 201, which is rotatably connected to the top of the storage tank 1. The top of the cover plate 201 is fixedly connected to a protective shell 202, and the top of the protective shell 202 is fixedly connected to a servo motor 203. The output end of the servo motor 203 passes through the protective shell 202 and is fixedly connected to a fan 204. The bottom of the protective shell 202 is fixedly connected to a filter plate 205. A plurality of heating copper wires 206 are fixedly connected to the inside of the cover plate 201, and the left and right sides of the bottom of the cover plate 201 are connected to air outlet tubes 207.

[0034] Specifically, when the paint in the storage tank 1 needs to be heated, the servo motor 203 is started, and the output end of the servo motor 203 drives the fan 204 to rotate. The airflow generated by the high-speed rotation of the fan 204 moves upward. Since the bottom of the protective shell 202 is fixedly connected to the filter plate 205, the filter plate 205 will filter out impurities and dust in the air when the airflow passes through the filter plate 205, ensuring that the airflow entering the storage tank 1 is clean and avoiding contamination of the paint. The heating copper wire 206 fixedly connected to the inside of the cover plate 201 will generate heat after being energized. The airflow is heated by the heating copper wire 206 when flowing through the inside of the cover plate 201, thereby becoming a hot airflow.

[0035] Reference Figure 1 and Figure 2 The left side of the storage tank 1 is fixedly connected to the feed port 9, and the top of the inner wall of the feed port 9 is slidably connected to a slide plate 10. The right side of the storage tank 1 is connected to the second discharge port 11, and the right end of the second discharge port 11 is threadedly connected to a cap 12. The left and right sides of the bottom of the storage tank 1 are fixedly connected to support plates 13, and the bottom of the support plates 13 are fixedly connected to soft rubber pads 14;

[0036] Specifically, when adding paint to the storage tank 1, the paint is injected from the feed port 9, and the slide plate 10 on the top of the inner wall of the feed port 9 is in a closed position in the initial state, which can prevent external impurities from entering the storage tank 1 when no material is fed. When using the slide plate 10, it slides to one side to open so that the paint can flow smoothly into the storage tank 1, and then the slide plate 10 is pushed back to its original position to play a sealing and protective role. When in use, take out the paint from the storage tank 1, open the cap 12 threadedly connected to the right end of the discharge port 11, and the paint flows out from the discharge port 11. The support plates 13 on the left and right sides of the bottom of the storage tank 1 play a stable supporting role for the entire storage tank 1. The support plates 13 can increase the contact area with the ground and improve the stability of the storage tank 1. The soft rubber pad 14 fixedly connected to the bottom of the support plate 13 has a shock-absorbing and buffering effect.

[0037] Reference Figure 3 The middle part of the front side of the cover plate 201 is rotatably connected to a handle 15, a groove 16 is provided in the middle part of the front side of the top of the storage tank 1, and a lock ring 17 is fixedly connected to the bottom end of the groove 16. Hinges 21 are fixedly connected to the left and right sides of the rear end of the storage tank 1. The cover plate 201 is rotatably connected to the storage tank 1 through the upper hinge 21. A sealing ring 18 is fixedly connected to the bottom of the cover plate 201. A sealing groove 19 is provided on the top of the storage tank 1. The sealing ring 18 is engaged with the sealing groove 19. A controller 20 is fixedly connected to the front side of the storage tank 1. The controller 20 is electrically connected to the servo motor 1 3 and the servo motor 2 203;

[0038] Specifically, by rotating the handle 15 in the middle of the front side of the cover 201, the cover 201 is rotated around the hinge 21 at the rear end of the storage tank 1 to open the cover 201. The hinge 21 plays the role of connection and rotation support to ensure that the cover 201 can be opened and closed smoothly. When the cover 201 needs to be closed, the handle 15 is rotated in the opposite direction to cover the top of the storage tank 1. The sealing ring 18 at the bottom of the cover 201 cooperates with the sealing groove 19 at the top of the storage tank 1 to form a sealing structure to prevent external air and impurities from entering the storage tank 1, thereby ensuring the quality of the paint. The controller 20 is electrically connected to the servo motor 1 3 and the servo motor 2 203, and can control the start, stop and running speed of the two motors.

[0039] Working principle: The servo motor 3 is started, and the output end drives the auger 4 to rotate inside the storage tank 1. When the auger 4 rotates, an upward driving force is generated through the paint in the storage tank 1, so that the paint circulates up and down in the storage tank 1 continuously, preventing the solid particles in the paint from settling at the bottom of the tank due to gravity. The horizontal plate 5 on the top of the auger 4 rotates synchronously with the scrapers 8 on the left and right sides of the bottom of the horizontal plate 5. During the rotation process, the scrapers 8 continuously scrape the inner wall of the storage tank 1 to prevent the solid particles in the paint from adhering to the tank wall and forming precipitation. At the same time, the paint that has already adhered to the tank wall is scraped off and returned to the paint flow system.

[0040] When the paint in the storage tank 1 is heated, the servo motor 203 is started, and the output end of the servo motor 203 drives the fan 204 to rotate. The airflow generated by the high-speed rotation of the fan 204 has an upward movement. The filter plate 205 at the bottom of the protective shell 202 plays an important role when the airflow passes through. The filter plate 205 can effectively filter out impurities and dust in the air, and generate heat through the heating copper wire 206 fixedly connected to the inside of the cover plate 201. The hot air flow is blown into the interior of the storage tank 1 through the air outlet ducts 207 fixedly connected on the left and right sides of the bottom of the cover plate 201. The hot air flow contacts the paint in the storage tank 1 and transfers the heat to the paint, thereby heating the paint.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
