Technical Field

[0001] The utility model belongs to the field of coating production, and in particular relates to a coating mixing kettle. Background Art

[0002] Paint, as the name implies, is a material used to coat the surface of an object. Under certain conditions, it can form a thin film. This film not only has the function of protecting the object, such as preventing external damage and corrosion, but also plays a decorative role and beautifies the appearance of the object. In addition, paint also has some special functions, such as insulation, rust prevention, mildew prevention, heat resistance, etc. These functions make paint widely used in various fields.

[0003] In the production process of coatings, various raw materials need to be mixed together and stirred evenly. The traditional stirring method is easy to produce solid deposition and stratification during the raw material stirring process, which affects the product quality of the coating. Therefore, a new type of coating mixing kettle is needed. Summary of the invention

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0023] See also Figure 1-4 A coating mixing kettle comprises a mixing kettle body 1, and a top cover 2 is installed on the top of the mixing kettle body 1. The mixing kettle body 1 is embedded with a heating wire and a temperature sensor, and the heating wire and the temperature sensor are used to control the mixing temperature of the coating. A discharge pipe connected to the inner cavity of the mixing kettle body 1 is extended from the bottom, and the discharge pipe is provided with a flange to connect with an external pipeline. The mixing kettle body 1 and the top cover 2 are fixedly connected by a number of annular evenly distributed bolts. A driving motor 3 is fixedly installed on the top of the top cover 2. The driving motor 3 is a low-speed and high-torque motor. The output shaft of the driving motor 3 is coaxially fixedly connected with a longitudinal driving shaft 6, and the bottom coaxial fixed sleeve of the longitudinal driving shaft 6 is provided with an agitator 13. The inner cavity wall of the mixing kettle body 1 is fixedly connected with a fixing frame 7, and the longitudinal driving shaft 6 rotates through the fixing frame 7, and the middle coaxial fixed sleeve of the longitudinal driving shaft 6 is provided with a worm 8, and the worm 8 is meshed with a worm wheel 10. The worm 8 arranged longitudinally drives the worm wheel 10 arranged transversely to rotate. The worm gear 10 is coaxially fixed with a transverse drive shaft 11, and the two ends of the transverse drive shaft 11 are coaxially fixedly connected with an impeller 12 for turning up the paint raw materials for mixing. The impeller 12 is provided with a plurality of annular blades evenly distributed. The rotating worm gear 10 drives the two impellers 12 to rotate through the transverse drive shaft 11, and the rotating impellers 12 continuously turn up the liquid at the bottom of the inner cavity of the mixing kettle body 1. The top cover 2 is equipped with a material spreading mechanism driven by the longitudinal drive shaft 6.

[0024] A feed pipe 4 and an exhaust pipe 5 are installed through the top of the top cover 2, and both the feed pipe 4 and the exhaust pipe 5 are provided with flanges to connect with external pipelines. The spreading mechanism includes: a feed pipe 4 that passes through the top cover 2, a spreading pipe 16 is rotatably installed at the bottom of the feed pipe 4, a second gear 15 is coaxially fixedly sleeved on the top of the spreading pipe 16, the second gear 15 is meshed with the first gear 14, and the first gear 14 is coaxially fixedly connected to the longitudinal drive shaft 6. The rotating first gear 14 drives the spreading pipe 16 to rotate through the second gear 15 meshed therewith. The rotating spreading pipe 16 spreads the coating raw materials into the inner cavity of the mixing kettle body 1, so that the newly added original dispersed materials are mixed into the original raw materials, which facilitates the uniform mixing of the coating raw materials.

[0025] The diameter of the first gear 14 is larger than that of the second gear 15. Since the diameter of the first gear 14 is larger than that of the second gear 15, the second gear 15 drives the material spreading tube 16 to rotate at a speed higher than that of the first gear 14, so that the material spreading tube 16 with the same speed as the second gear 15 can throw out the raw materials inside.

[0026] The material spreading pipe 16 is funnel-shaped, and the bottom outlet of the material spreading pipe 16 is bent. The angle between the bottom bend of the material spreading pipe 16 and the vertical direction is greater than 0 degrees and less than 90 degrees.

[0027] The top of the fixed frame 7 is fixedly connected with a rotating seat 9, and the rotating seat 9 is rotatably connected with the transverse driving shaft 11. The rotating seat 9 is used to install the worm gear 10 and the transverse driving shaft 11 that are coaxially fixedly connected together. The vertical cylinder of the fixed frame 7 is rotatably penetrated by the longitudinal driving shaft 6, and the cross bar of the fixed frame 7 is fixedly connected with the inner wall of the mixing kettle body 1.

[0028] The blades of the stirrer 13 fit the inner cavity bottom wall of the mixing kettle body 1. The blades of the stirrer 13 are arranged obliquely, and the rotating blades of the stirrer 13 can scoop up the solid raw materials deposited on the bottom of the mixing kettle body 1 for mixing and stirring while stirring the coating raw materials.

[0029] Working principle:

[0030] When in use, the driving motor 3 drives the longitudinal driving shaft 6 to rotate, and then various raw materials of coatings are added in sequence from the feeding pipe 4. After the raw materials flow into the spreading pipe 16 from the feeding pipe 4, the rotating spreading pipe 16 rotates and spreads the raw materials into the inner cavity of the mixing kettle body 1 through the curved pipe at the bottom thereof, wherein the rotating longitudinal driving shaft 6 drives the spreading pipe 16 to rotate through the first gear 14 and the second gear 15. The high rotation speed of the spreading pipe 16 can throw out the raw materials inside, and the thrown raw materials are dispersed and mixed into the raw materials in the original mixing kettle body 1;

[0031] At the same time, the longitudinal drive shaft 6 drives the agitator 13 to rotate and stir the raw materials of the paint to mix evenly. The rotating blades of the agitator 13 can scoop up the solid raw materials deposited on the bottom of the mixing kettle body 1 for mixing and stirring while stirring the raw materials of the paint. The longitudinal drive shaft 6 drives the agitator 13 to rotate while also driving the worm 8 to rotate. The worm 8 drives the transverse drive shaft 11 to rotate through the worm gear 10 meshing with it, thereby driving the impellers 12 at both ends of the transverse drive shaft 11 to rotate, so that the impeller 12 continuously turns over the liquid stirred upward by the agitator 13 at the bottom of the inner cavity of the mixing kettle body 1. Under the joint action of the agitator 13 and the impeller 12, the various paint raw materials in the mixing kettle body 1 are fully stirred to reduce stratification.
