Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments (for the convenience of description and understanding, the above is described with the upper side of Figure 2 being the upper side). Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-5, the present utility model provides a technical solution: a mixing device for microporous heat-insulating self-leveling material, including a base 1. On the upper end of the base 1, brackets 2 are symmetrically arranged. A mixing barrel 3 is horizontally placed on the brackets 2. At the upper end of the outer side of the mixing barrel 3, a feed inlet 7 is provided. At the lower end of the outer side of the mixing barrel 3, a discharge outlet 8 is provided. At one end of the mixing barrel 3, a rotating motor 4 is provided. The output end of the rotating motor 4 is connected to a stirring shaft 5. The stirring shaft 5 is located inside the mixing barrel 3. On the outer side of the stirring shaft 5, stirring blades 6 are provided. At the lower end of the outer side of the mixing barrel 3, a gas collecting box 11 is provided. A plurality of air outlet holes 12 are evenly distributed on the gas collecting box 11. The air outlet holes 12 penetrate through the mixing barrel 3. The air outlet holes 12 are located at the gap between the stirring blades 6 and the inner wall of the mixing barrel 3. One end of the gas collecting box 11 is connected to an air pump 9 through a connecting air pipe 10. The air pump 9 is fixed on the upper surface of the base 1. The air pressure is provided by the air pump 9 and air is blown into the gas collecting box 11 through the connecting air pipe 10. The air flow blows air into the mixing barrel 3 through the air outlet holes 12, so that various powder raw materials are evenly mixed.

[0019] Further, in order to prevent the raw materials from escaping during exhaust, a exhaust pipe 13 is provided at the upper end of the outer side of the mixing barrel 3. A blocking net 14 is provided inside the exhaust pipe 13. The mesh size of the blocking net 14 is smaller than the size of the powder raw materials.

[0020] Further, in order to facilitate the stirring blades 6 to have the functions of both stirring and feeding, the stirring blades 6 are of a spiral structure. The outer end of the stirring blades 6 is in contact with the inner side surface of the mixing barrel 3.

[0021] Further, for the convenience of feeding and discharging, the feed inlet 7 is arranged on the side far from the rotating motor 4, and the discharge outlet 8 is arranged on the side close to the rotating motor 4. Both the feed inlet 7 and the discharge outlet 8 are equipped with corresponding end covers.

[0022] Further, in order to facilitate the addition of auxiliary liquid raw materials and make the liquid raw materials and powder raw materials evenly mixed, a atomized material inlet 15 is provided on one side of the feed inlet 7. An atomizing nozzle 16 is provided inside the atomized material inlet 15. The atomizing nozzle 16 faces the inside of the mixing barrel 3. The upper end of the atomizing nozzle 16 is connected to an atomizer 18 through an atomizing connecting pipe 17. The atomizer 18 is fixed on the upper surface of the base 1. The auxiliary liquid raw materials are added into the atomizer 18 and are pressed into the atomizing connecting pipe 17. The liquid raw materials are sprayed into the mixing barrel 3 in a mist form through the atomizing nozzles 16, ensuring that the liquid raw materials and various powder raw materials are evenly mixed.

[0023] In use: Add various powdery raw materials into the mixing cylinder 3 through the feeding port 7 according to the ratio. After the addition of the powdery raw materials is completed, start the rotating motor 4. The rotating motor 4 drives the spiral stirring blades 6 to rotate, mixing the raw materials and feeding them towards the discharge port 8 at the same time. At this time, turn on the air pump 9, introduce compressed air into the air collecting box 11, and then provide air flow into the mixing cylinder 3 through multiple air holes 12 on the mixing cylinder 3. Under the action of the air flow, the powdery raw materials are lifted up for full mixing. If a liquid auxiliary raw material needs to be added, add the liquid auxiliary raw material into the atomizer 18 and spray it into the mixing cylinder 3 through the atomizing nozzle 16, so that the liquid auxiliary raw material is evenly mixed with each powdery raw material.

[0024] The utility model can ensure the uniform mixing between powdery raw materials, making the finished microporous thermal insulation material have uniform texture and good thermal insulation performance, effectively improving the product quality.
