DETAILED DESCRIPTION

[0021] The utility model will be further explained in detail in combination with the drawings.

[0022] Refer to Figure 1 , Figure 2A refrigerant material mixing device includes a mixing vessel 1, with a feeding pipe 2 connected to the top and a discharge pipe 3 connected to the bottom of the mixing vessel 1, and valves respectively installed on the feeding pipe 2 and the discharge pipe 3. An agitator 4 is installed inside the mixing vessel 1 to achieve mixing and stirring of liquid raw materials.

[0023] Reference Figure 1 , Figure 2 The mixing vessel 1 is equipped with a vent valve 5 at its top. An annular jet pipe 6 is located at the lower end of the mixing vessel 1, and the jet pipe 6 is connected to the inner wall of the mixing vessel 1 by multiple support rods. At the same time, multiple jet holes 7 are provided through the top of the jet pipe 6, and the multiple jet holes 7 are arranged at equal intervals along the circumference of the jet pipe 6.

[0024] Reference Figure 1 , Figure 2 An air pump 8 is fixedly connected to the bottom of the mixing vessel 1. An air supply pipe 9 is connected to the exhaust end of the air pump 8. The air supply pipe 9 extends into the mixing vessel 1 and is connected to the air jet pipe 6. At the same time, a one-way valve 10 is installed in the air supply pipe 9. The one-way valve 10 is used to restrict the liquid raw materials in the mixing vessel 1 from flowing back into the air pump 8.

[0025] Liquid raw materials are fed into mixing vessel 1 through feeding pipe 2, and then mixed and stirred by agitator 4. Simultaneously, air pump 8 is activated, and air enters jet pipe 6 through air supply pipe 9 and is discharged through multiple jet holes 7. At this time, air forms bubbles within the liquid raw materials and rises, causing the liquid raw materials to move, breaking their natural movement patterns, and promoting relative motion between the components. This allows the liquid raw materials to be fully mixed in a shorter time, improving both mixing efficiency and production efficiency.

[0026] Reference Figure 1 , Figure 2 A bubble-forming mesh plate 11 is horizontally fixedly connected to the lower end of the mixing tank 1. The jet pipe 6 is located below the bubble-forming mesh plate 11, and the diameter of the jet hole 7 is larger than the diameter of the mesh hole of the bubble-forming mesh plate 11. When the bubbles move upward and pass through the bubble mesh plate 11, the bubble mesh plate 11 can break the bubbles to form finer bubbles, further promoting the relative movement effect between the components of the raw materials.

[0027] Reference Figure 1 , Figure 2, the agitator 4 comprises a stirring shaft 41 arranged vertically in the mixing kettle 1, and the bottom of the stirring shaft 41 is rotationally connected with the inner wall of the bottom side of the mixing kettle 1, the top of the mixing kettle 1 is fixedly connected with a driving motor 42, the output shaft of the driving motor 42 is coaxially fixedly connected with the stirring shaft 41, so that the stirring shaft 41 can rotate stably. Two stirring blades 43 are welded and fixed on the stirring shaft 41, and the two stirring blades 43 are double helix-shaped, and a plurality of stirring holes 44 are arranged on each stirring blade 43.

[0028] By arranging the double helix-shaped stirring blades 43, the movement effect of the liquid raw materials in the vertical and horizontal directions can be promoted, the movement rule of the liquid raw materials is broken, so that the liquid raw materials can be better mixed. Meanwhile, the stirring holes 44 can break the movement rule between the components of the liquid raw materials, so that the liquid raw materials can be quickly mixed, so as to improve the production efficiency.

[0029] The specific embodiments are only an explanation of the utility model, and are not a limitation of the utility model, and the person skilled in the art can make a modification without creative contribution according to the need after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
