[0019] As Figures 1-3 shown, a premixing device for plastering gypsum admixture includes a mixing main body 1. An upper part of the mixing main body 1 is provided with a feed pipe 2, and a bottom of the mixing main body 1 is provided with a discharge pipe 3. It also includes a stirring cylinder 4, a stirring mechanism 5 and a pressure mixing mechanism 6. The stirring cylinder 4 is fixedly connected to a center of an upper part of the mixing main body 1 and is communicated with the mixing main body 1. The pressure mixing mechanism 6 is arranged at a connection part between the mixing main body 1 and the stirring cylinder 4. The stirring mechanism 5 is rotatably arranged in the mixing main body 1 and extends through the pressure mixing mechanism 6 into the stirring cylinder 4. An upper end of the stirring cylinder 4 is hinged with an upper cover 7 for sealing the stirring cylinder 4. Plastering gypsum is added into the mixing main body 1 through the feed pipe 2, or the powdery admixture and the plastering gypsum can be added into the mixing main body 1 at the same time. The admixture and the plastering gypsum are pushed to be stirred in the mixing main body 1 through the stirring mechanism 5. The upper cover 7 is opened, and water is added into the stirring cylinder 4, or different states of admixtures can be added into it. When the stirring mechanism 5 rotates, the water and the admixture in the stirring cylinder 4 are stirred and mixed, and the admixture is dissolved in the water. Then, the pressure mixing mechanism 6 extracts the gas inside the mixing main body 1 and pumps it into the stirring cylinder 4, and the admixture dissolved in the water is pressed into the mixing main body 1 to improve the mixing uniformity of the admixture and the plastering gypsum.

[0020] As Figure 2 and Figure 3As shown in the figure, in order to achieve synchronous stirring inside the mixing drum 4 and the mixing main body 1, the stirring mechanism 5 includes a rotating shaft 12, a stirring plate 13, a spiral blade 14, a stirring rod 15 and a rotating motor 16. One end of the rotating shaft 12 is rotatably connected to the inner bottom wall of the mixing main body 1, and the other end of the rotating shaft 12 penetrates through the baffle 8 and extends into the mixing drum 4. The stirring plate 13 is fixedly connected to the upper part of the outer side wall of the rotating shaft 12. The spiral blade 14 is wound around the middle part of the outer side wall of the rotating shaft 12. The stirring rod 15 is fixedly connected to the bottom of the outer side wall of the rotating shaft 12. The rotating motor 16 is installed on the bottom wall of the mixing main body 1, and the output end of the rotating motor 16 is connected to the bottom of the rotating shaft 12. The stirring plates 13 are arranged at equal intervals along the axial direction of the rotating shaft 12 and are located inside the mixing drum 4. The spiral blade 14 and the stirring rod 15 are located inside the mixing main body 1, and the spiral blade 14 is located above the stirring rod 15. By driving the rotating shaft 12 to rotate through the rotating motor 16, the spiral blade 14 and the stirring rod 15 in the mixing main body 1 and the stirring plates 13 in the mixing drum rotate synchronously. The stirring rod 15 contacts the inner bottom wall of the mixing main body 1 to scrape the plastering gypsum. At the same time, the spiral blade 14 pushes the plastering gypsum upward or downward. When the powdery admixture is added to the mixing main body 1, it promotes the mixing of the powdery admixture and the plastering gypsum. When the admixtures in different states are added to the mixing drum 4, the rotating stirring plates 13 push the admixtures to fuse with water.

[0021] As Figures 2-4 shown, in order to automatically add water or the aqueous solution of the fused admixture in the mixing drum 4 into the mixing main body 1, the pressure mixing mechanism 6 includes a baffle 8 and an air pump 9. The baffle 8 is fixedly connected to the bottom of the inner side wall of the mixing drum 4. The baffle 8 is located at the connection between the mixing drum 4 and the mixing main body 1. A through hole 20 is opened in the baffle 8. The through holes 20 are arranged at equal intervals. A rubber valve 10 is arranged in the through hole 20. The air pump 9 is installed on the upper part of the mixing main body 1. The intake end of the air pump 9 communicates with the inside of the mixing main body 1. The outlet end of the air pump 9 is connected with an intake hose 11. The other end of the intake hose 11 is communicated with the mixing drum 4. The air pump 9 is driven to extract the gas inside the mixing main body 1 and pump the gas into the mixing drum 4 to press down the water or the aqueous solution in the mixing drum 4, which passes through the rubber valve 10 in the through hole 20 and is squeezed into the mixing main body 1 to achieve the automatic addition of water or the aqueous solution.

[0022] Among them, a plug one 17 is threadedly connected to the upper part of the feed pipe 2, and a plug two 18 is threadedly connected to the bottom of the discharge pipe 3. Support legs 19 are arranged on the bottom wall of the mixing main body 1. The support legs 19 are arranged symmetrically in pairs. The plug one 17 is used to seal the feed pipe 2, and the plug two 18 is used to seal the discharge pipe 3. The support legs 19 stably support the placement of the mixing main body 1.

[0023] During specific use, in the initial state, the first plug 17 and the second plug 18 are respectively installed in the feed pipe 2 and the discharge pipe 3. Remove the first plug 17, and add plastering gypsum into the mixing main body 1 through the feed pipe 2. It is also possible to add the powdery admixture and the plastering gypsum into the mixing main body 1 at the same time. Meanwhile, open the upper cover 7 and add water into the mixing drum 4. Different states of admixtures can also be added into it. After adding, install the first plug 17 in the feed pipe 2;

[0024] Drive the rotation motor 16 to rotate, so that the spiral blades 14 and the stirring rods 15 in the mixing main body 1 rotate synchronously with the stirring plates 13 in the mixing drum. The stirring rods 15 contact the inner bottom wall of the mixing main body 1 to scrape the plastering gypsum. At the same time, the spiral blades 14 push the plastering gypsum upward or downward. When the powdery admixture is added into the mixing main body 1, it promotes the mixing of the powdery admixture and the plastering gypsum. When different states of admixtures are added into the mixing drum 4, the stirring plates 13 rotate to push the admixtures to blend with water, realizing different ways of adding admixtures;

[0025] Finally, drive the air pump 9 to extract the gas inside the mixing main body 1, pump the gas into the mixing drum 4, press down the water or aqueous solution in the mixing drum 4, pass through the rubber valve 10 in the through hole 20, and squeeze it into the mixing main body 1 to realize the automatic addition of water or aqueous solution. Then, use the rotation of the spiral blades 14 and the stirring rods 15 to mix the water or aqueous solution with the plastering gypsum. After mixing evenly, remove the second plug 18 and discharge the material through the discharge pipe 3.
