[0002] Sodium silicate, with the chemical formula Na2O·nSiO2, is commonly known as sodium silicate. Its aqueous solution is commonly known as water glass and is a mineral binder. Sodium silicate can be divided into two categories based on its physical state: liquid sodium silicate and solid sodium silicate. Solid sodium silicate is an intermediate product, often appearing light blue. The production process for solid sodium silicate primarily involves dry and wet methods. The dry method involves mixing quartz sand and soda ash in a specific proportion. The mixture is then heated to approximately 1400°C in a reverberatory furnace to form molten sodium silicate. The molten sodium silicate is then cooled and solidified to form solid sodium silicate. Finally, the solidified sodium silicate is crushed and sieved to obtain the desired particle size.

[0032] like Figure 1As shown, the mixing device 2 includes an outer cylinder 2-1, a lifting assembly 2-2 is arranged inside the cylinder wall of the outer cylinder 2-1, the movable end of the lifting assembly 2-2 is slidingly connected to the inner cylinder 2-3, a coaxial bidirectional stirring assembly 2-4 is arranged in the inner cylinder 2-3, the coaxial bidirectional stirring assembly 2-4 is dynamically connected to the driving assembly 2-5, and the driving assembly 2-5 is fixedly connected to the top of the outer cylinder 2-1.

[0033] A discharge pipe 2-6 is provided at the bottom of the inner cylinder 2-3. The discharge pipe 2-6 is equipped with an electric valve and is located above the feed conveyor 3. The material, after being stirred and mixed in the mixing device 2, is discharged from the discharge pipe 2-6 onto the feed conveyor 3. The feed conveyor 3 transports the material to the electric kiln 4 for melting.

[0034] like Figures 3 to 5 As shown, the drive assembly 2-5 includes a drive motor 2-5-1, which is fixedly connected to a protective housing 2-5-7.

[0035] The fixed plate 2-5-5 is fixedly connected in the protective shell 2-5-7. The fixed plate 2-5-5 is located above the transmission gear 2-5-3, and the fixed plate 2-5-5 is arranged on the outside of the output end of the drive motor 2-5-1 to avoid interfering with the rotation of the output end of the drive motor 2-5-1. The gear shaft 2-5-6 of the transmission gear 2-5-3 is rotatably connected to the fixed plate 2-5-5.

[0036] The coaxial bidirectional stirring assembly 2-4 includes a main stirring shaft 2-4-1 and a driven stirring shaft 2-4-2. The top of the main stirring shaft 2-4-1 is fixedly connected to the main gear 2-5-2, and the bottom of the main stirring shaft 2-4-1 is fixedly connected to the main stirring blade 2-4-3.

[0037] The driven stirring shaft 2-4-2 is a sleeve structure, and is movably mounted on the outside of the main stirring shaft 2-4-1. The top end of the driven stirring shaft 2-4-2 is fixedly connected to the gear sleeve 2-5-4, and the bottom end of the driven stirring shaft 2-4-2 is fixedly connected to the driven stirring blade 2-4-4. The gear sleeve 2-5-4 is rotatably connected to the top of the outer cylinder 2-1 via the first bearing 2-4-5. The gear sleeve 2-5-4 is rotatably connected to the protective shell 2-5-7 via the second bearing 2-4-6.

[0038] like Figure 5 As shown, the second bearing 2-4-6 is a tapered roller bearing, the inner ring raceway of the second bearing 2-4-6 is interference fit with the outer wall of the gear sleeve 2-5-4, and the outer ring raceway of the second bearing 2-4-6 is fixedly connected to the protective shell 2-5-7.

[0039] When the main gear 2-5-2 rotates, it drives the transmission gear 2-5-3 to rotate, and then drives the gear sleeve 2-5-4 to rotate in the opposite direction to the main gear 2-5-2, so that the main stirring blade 2-4-3 and the driven stirring blade 2-4-4 can rotate in opposite directions at the same time.

[0040] like Figure 5 and Figure 6 As shown, the lifting assembly 2-2 includes a screw 2-2-1, of which multiple screws 2-2-1 are provided. The bottom of the screw 2-2-1 is fixedly connected to the output end of the output motor 2-2-2. The output motor 2-2-2 is fixedly connected to the outer cylinder 2-1 via a bracket.

The threaded sleeve 2-2-3 is slidably connected to the connecting rod 2-2-4, which is fixedly connected to the inner wall of the outer cylinder 2-1. The output motor 2-2-2 is started to rotate, driving the screw 2-2-1 to rotate, which in turn drives the threaded sleeve 2-2-3 to move upward or downward, thereby driving the entire inner barrel 2-3 to move upward or downward. By controlling the output motor 2-2-2 to continuously rotate forward and reverse, the material in the inner barrel 2-3 is continuously thrown up and down, promoting mixing of the bottom layer with the upper layer, improving the mixing effect, and preventing adhesion of the bottom layer. In this embodiment, three screws 2-2-1 are provided.

[0041] like Figure 5 As shown, a spring washer 2-7 is provided on the inner wall of the bottom of the outer cylinder 2-1. The spring washer 2-7 can disperse part of the pressure for the screw 2-2-1 when the inner cylinder 2-3 moves downward, thereby playing a buffering role.

[0042] In this embodiment, the inner cylinder inlet 2-3-1 of the inner cylinder 2-3 is connected to the discharge port of the grinding device 1 through elastic flexible fabric to ensure that the material can fall into it normally when the inner cylinder 2-3 moves up and down.

[0043] The working principle of this utility model is as follows:

[0044] First, material is fed into the feed port of grinding device 1. After being crushed and ground by grinding roller 1-2, the material falls onto vibrating screen 1-3. After being vibrated and screened by vibrating screen 1-3, the material enters mixing device 2. Drive motor 2-5-1 is activated, driving motor 2-5-1 to rotate main stirring shaft 2-4-1 and main stirring blades 2-4-3. Main gear 2-5-2, via transmission gear 2-5-3, causes gear sleeve 2-5-4 to rotate in the opposite direction. The gear sleeve 2-5-4 drives driven stirring blades 2-4-4 in the opposite direction of the main stirring blades 2-4-3. This combined rotation and stirring achieves a better mixing effect. Simultaneously, output motor 2-2-2 is controlled to rotate continuously, driving threaded sleeve 2-2-3 to reciprocate up and down, thereby driving the entire inner barrel 2-3 up and down, causing the material inside to be constantly thrown up and down, promoting mixing of the bottom and upper materials, improving the mixing effect, and preventing adhesion of the bottom materials. After the stirring and mixing is completed, the discharge pipe 2-6 is opened, and the material stirred and mixed in the mixing device 2 is discharged from the discharge pipe 2-6 and falls onto the feeding conveyor 3, which transports it to the electric kiln 4 for melting process.

[0045] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
