[0002] Coatings, known as paints in traditional Chinese names. A coating is a continuous film that is applied to the surface of an object to be protected or decorated and can form a firm attachment to the object being coated. It is usually mainly composed of resin, oil or emulsion, with or without pigments and fillers, and corresponding additives are added, and it is a viscous liquid prepared with organic solvents or water.

[0003] When producing and processing coatings, it is necessary to formulate and process based on various emulsions. Therefore, it is necessary to store emulsions. However, emulsions are prone to precipitation and even stratification during storage, and continuous stirring is required. However, the stirring effect of existing storage tanks is not ideal. Since existing storage tanks are generally cylindrical, when emulsions are stirred and discharged, the side walls of the storage tank are prone to adhesion of emulsions, which not only is not conducive to sufficient stirring but also causes waste of emulsions during discharging. Therefore, an emulsion storage tank for coating production is needed to solve the above problems. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The following is combined with Figures 1 - 3 The specific implementation modes of the present utility model are further described in detail.

[0023] Depend on Figures 1 - 3 The utility model includes a tank body 1, which is in a truncated cone shape. In order to achieve the purpose of fully stirring the emulsion in the tank body 1, a plurality of rotatable stirring rods 2 are provided inside the tank body 1, and a plurality of stirring frames 3 are rotatably connected to the outer side of each stirring rod 2. A plurality of elastic plates 4 are connected between each stirring rod 2 and the corresponding stirring frame 3. The upper and lower sides of the elastic plates 4 are respectively fixedly connected to the stirring frame 3 and the stirring rod 2. The elastic plates 4 have elastic force and can produce a certain elastic deformation when subjected to force. The elastic plates 4 and the stirring frames 3 cooperate with each other to form a structure for stirring the emulsion and removing the emulsion in the tank. A rotatable power rod 5 is provided inside the tank body 1, and a planetary gear set 6 is respectively connected to the front and rear sides of the power rod 5. An inlet 7 is provided on the upper side of the tank body 1, and a discharge port 8 is provided on the lower side of the tank body 1.

[0024] Furthermore, in order to make more turbulence exist during stirring, the planetary gear set 6 includes a sun gear 9 rotatably connected to the tank body 1, a gear ring 10 fixedly connected to the tank body 1 is provided on the outer side of the sun gear 9, a plurality of planetary gears 11 are meshed between the sun gear 9 and the gear ring 10, and the front and rear sides of the power rod 5 are fixedly connected to the corresponding sun gear 9;

[0025] It should be noted that, since the tank body 1 is in a truncated cone shape, that is, the radius of the front portion of the tank body 1 is larger, and the radius of the rear portion is smaller, the radius of each gear in the planetary gear set 6 located at the front portion of the tank body 1 is larger than the radius of each gear in the planetary gear set 6 located at the rear portion of the tank body 1, and further, the number of teeth of each identical component in the two planetary gear sets 6 is the same;

[0026] When in use, when the power rod 5 rotates, it will drive the two sun gears 9 to rotate, and then under the joint action of the sun gear 9 and the gear ring 10, the planetary gear 11 will revolve around the sun gear 9 and rotate at the same time.

[0027] Further, in order to scrape the emulsion on the inner wall of the tank body 1, a universal joint 12 is fixedly connected to the front and rear sides of each stirring rod 2, and one side of each universal joint 12 away from the stirring rod 2 is fixedly connected to the corresponding planetary gear 11;

[0028] During use, when the planetary gear 11 rotates, it will drive the corresponding stirring rod 2 to rotate through the universal joint 12. Each stirring rod 2 is parallel to the side wall of the tank body 1, that is, when each stirring rod 2 is operating, the distance between it and the inner wall of the tank body 1 remains unchanged.

[0029] Further, a first motor 13 is fixedly connected to the front side of the tank body 1. The output end of the first motor 13 is fixedly connected to the corresponding sun gear 9. The first motor 13 is a servo motor, which will not be described in detail here. Further, a controller, such as a PLC controller, is built into the first motor 13, which can control the rotation speed of the first motor 13.

[0030] Further, in order to facilitate discharging, a solenoid valve 14 is provided below the discharge port 8. The solenoid valve 14 is a prior art and will not be described in detail here. Further, the solenoid valve 14 is electrically connected to the controller, and the opening and closing of the solenoid valve 14 can be controlled through the controller.

[0031] Further, in order to make the stirring inside the tank body 1 more uniform, a stirring spiral 15 is fixedly connected to the outer side of the power rod 5. The stirring spiral 15 is adapted to the shape of the tank body 1, that is, the stirring spiral 15 also has a larger radius at the front and a smaller radius at the rear;

[0032] It should be further noted that by designing the tank body 1 as a frustum shape, when stirring the materials inside the tank body 1, the flow rate of the liquid at the front part inside the tank body 1 can be made greater than that at the rear part. According to Bernoulli's theorem, at this time, the pressure at the front part of the tank body 1 is less than that at the rear part, which can further promote the mutual flow between the front and rear materials inside the tank body 1 and make the material mixing more uniform. And setting the stirring spiral 15 can further increase the material exchange and mixing between the front and rear inside the tank body 1.

[0033] When the utility model is in use, the first motor 13 can be started. The first motor 13 drives each sun gear 9 and the power rod 5 to rotate. Under the combined action of the sun gear 9 and the gear ring 10, the planetary gear 11 revolves around the sun gear 9 while rotating on its own axis, thereby driving each stirring rod 2 to move together with the sun gear 9. When the stirring rod 2 rotates, it will drive the stirring frame 3 to rotate together. Since the width of each stirring frame 3 is greater than the distance between the stirring rod 2 and the inner wall of the tank body 1, when the stirring frame 3 contacts the inner wall of the tank body 1 under the action of the stirring rod 2, it will rotate relative to the stirring rod 2. At this time, the elastic plate 4 deforms and stores energy, and the side of the stirring frame 3 away from the stirring rod 2 contacts the inner wall of the tank body 1, which can scrape the emulsion on the inner wall of the tank body 1. At the same time, under the action of the stirring spiral 15, the inside of the tank body 1 is fully stirred. When discharging is required, the solenoid valve 14 can be opened to open the discharge port 8, and the emulsion on the inner wall of the tank body 1 is scraped by the stirring frame 3, so that the emulsion inside the tank body 1 can be fully discharged.

[0034] The utility model has a novel structure, ingenious concept, simple and convenient operation. Through this design, the purpose of fully stirring the emulsion in the tank body 1 is effectively achieved, making there more turbulent flows during stirring, adding the function of scraping the emulsion on the inner wall of the tank body 1, facilitating the staff to unload the material, and reducing the waste of the emulsion.

[0035] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
