Detailed implementation manners

[0023] The present utility model will be further described below with reference to the drawings and embodiments.

[0024] Please refer to Figures 1 - 6, the present utility model provides an embodiment: a glass batch mixing and pre-calcining device outside the kiln, including a mixing barrel body 1; further including a support plate 5, a first scraper 6 and a second scraper 8. The upper and lower ends of the mixing barrel body 1 are respectively fixedly connected with a first feed pipe 9 and a first discharge pipe 10. The middle part of the left end of the mixing barrel body 1 is rotatably connected with a rotating disk 2. The right end of the rotating disk 2 is fixedly connected with a first rotating ring 3. The middle part of the right end of the mixing barrel body 1 is rotatably connected with a second rotating ring 4. The upper ends of the first rotating ring 3 and the second rotating ring 4 are fixedly connected with the same support plate 5. The upper ends of the two support plates 5 are fixedly connected with a first scraper 6. Between the left and right inner walls of the mixing barrel body 1 and near the lower side, a bidirectional screw 7 is rotatably connected. Symmetrically threaded on the outer sides of both ends of the bidirectional screw 7 are second scrapers 8. When the internal material mixing is completed, the mixed material is exported from the first discharge pipe 10. Then, to clean the material adhering to the inner wall of the mixing barrel body 1, the rotating disk 2 can be driven to rotate back and forth in a circular motion by an appropriate angle, controlling to avoid affecting the second scraper 8. The first rotating ring 3 and the left support plate 5 rotate together, cooperating with the second rotating ring 4 and the right support plate 5 to drive the first scraper 6 to rotate as well. Thus, the two support plates 5 scrape the left and right inner walls of the mixing barrel body 1 to a certain extent, and the first scraper 6 scrapes the circumferential inner wall of the mixing barrel body 1. When the cleaning is almost done, the bidirectional screw 7 is driven to rotate, and the two second scrapers 8 move relatively closer to push the accumulated falling material on the lower inner wall of the mixing barrel body 1, and finally the falling material is completed from the first discharge pipe 10. The device can scrape off a large area of the material adhering to the inner wall of the mixing barrel body 1 and finally push it out, thus facilitating the device to discharge materials, saving raw materials, also facilitating subsequent cleaning work, reducing the burden on workers, and saving production costs.

[0025] Please refer to Figures 1 - 5 , in this embodiment, a U-shaped support frame 11 is fixedly connected to the outer side of the left end of the mixing barrel body 1. A first motor 12 is fixedly installed inside the U-shaped support frame 11. The output shaft of the first motor 12 is fixedly connected to the left end of the rotating disk 2. By starting the first motor 12, the rotating disk 2 is driven to rotate. A motor 2 13 is fixedly installed at a position near the lower side of the outer side of the right end of the mixing barrel body 1. The output shaft of the motor 2 13 passes through the right wall of the mixing barrel body 1 and is fixedly connected to the bidirectional screw 7. By starting the motor 2 13, the bidirectional screw 7 is driven to rotate. A limiting ring 14 is fixedly connected to the outer side of the rotating disk 2. The limiting ring 14 is movably arranged inside the left inner wall of the mixing barrel body 1. The surface of the second scraper 8 is set as a curved surface. The limiting ring 14 limits the position of the rotating disk 2 to prevent it from falling off, and at the same time also maintains good sealing inside the mixing barrel body 1 when the rotating disk 2 rotates. The curved surface design of the second scraper 8 can well reduce the accumulation of mixed materials on the second scraper 8.

[0026] Please refer to Figure 1 , Figure 3 andFigure 6 , in this embodiment, a heating furnace 15 is fixedly connected to the left side of the upper end of the mixing barrel body 1. A heating resistance wire is arranged on the inner wall of the heating furnace 15. The upper end of the heating furnace 15 is fixedly connected with a second feed pipe 16 and an air outlet pipe 17. A cover 18 is arranged at the upper end of the second feed pipe 16. First, limestone and dolomite in the raw materials can be poured into the heating furnace 15 from the second feed pipe 16 for heating, and the two raw materials are subjected to pre-decomposition treatment outside the kiln. The decomposition of carbonate is a violent endothermic process, and the generated carbon dioxide gas is discharged from the air outlet pipe 17 in advance. The outside-the-kiln decomposition of carbonate can reduce the bubble content in the glass liquid, shorten the clarification process, reduce the bubble amount in the glass product, and avoid the decomposition process of carbonate in the melting furnace. Because the violent decomposition process is accompanied by a large number of bubbles, and the viscosity of the glass liquid is very high, the bubbles inside are not easy to float to the surface and are easy to stay inside and finally form defects, while the outside-the-kiln decomposition avoids this situation, and the bubbles in the melting process are greatly reduced. A second discharge pipe 19 is fixedly connected between the heating furnace 15 and the mixing barrel body 1. A cylinder 20 is fixedly installed at the left end inside the heating furnace 15. The movable end of the cylinder 20 is fixedly connected with a pushing plate 21. After the decomposition of carbonate is completed, the cylinder 20 is started to push the material to the right through the pushing plate 21, so that the material falls into the mixing barrel body 1 from the second discharge pipe 19 and continues to be mixed with other materials. A stirring shaft 22 is rotatably connected between the right end of the rotating disk 2 and the right wall of the mixing barrel body 1. Stirring rods 23 are fixedly connected to the outside of the stirring shaft 22. A third motor 24 is fixedly installed on the outside of the right end of the mixing barrel body 1. The output shaft of the third motor 24 passes through the right wall of the mixing barrel body 1 and is fixedly connected with the stirring shaft 22. The third motor 24 is started to drive the stirring shaft 22 to rotate, and each stirring rod 23 rotates to stir and mix the materials.

[0027] When working, the limestone and dolomite in the raw materials are first poured into the heating furnace 15 from the feed pipe 2 16 for heating, and the two raw materials are pre-decomposed outside the kiln. The carbon dioxide gas generated by the decomposition of the carbonate is discharged from the outlet pipe 17 in advance. After the decomposition of the carbonate is completed, the cylinder 20 is started to push the material to the right through the push plate 21, so that the material falls into the mixing barrel body 1 from the discharge pipe 2 19, and then other types of raw materials are added to the mixing barrel body 1 from the feed pipe 1 9, and the motor 3 24 is started to drive the stirring shaft 22 to rotate, and each stirring rod 23 rotates to stir the mixed material. After the mixing is completed, it is discharged from the discharge pipe 10, and then the material attached to the inner wall of the mixing barrel body 1 is To clean the material, you can first start the motor 12 to drive the rotating disk 2 to rotate back and forth at an appropriate angle, control it to avoid affecting the scraper 2 8, the swivel 3 and the left support plate 5 rotate together, cooperate with the swivel 2 4 and the right support plate 5, drive the scraper 6 to rotate, so that the two support plates 5 scrape and clean the left and right inner walls of the mixing barrel body 1 to a certain extent, and the scraper 6 scrapes and cleans the circumferential inner wall of the mixing barrel body 1. When the cleaning is almost done, start the motor 2 13 to drive the bidirectional screw 7 to rotate, and the two scrapers 2 8 move relatively close to each other to push the fallen materials accumulated on the lower inner wall of the mixing barrel body 1, and finally complete the falling of the materials from the discharge pipe 10.

[0028] The material that is attached to the inner wall of the mixing barrel body 1 is cleaned by the above steps after the mixed material is discharged. The two support plates 5 that swing back and forth at a certain angle are controlled to scrape and clean the left and right inner walls of the mixing barrel body 1 to a certain extent. The swinging scraper 6 scrapes and cleans the circumferential inner wall of the mixing barrel body 1. The two scrapers 2 8 are driven by the rotation of the bidirectional screw 7 to move relatively close to each other, and the accumulated falling materials on the bottom wall of the mixing barrel body 1 are pushed and the falling materials are completed from the discharge pipe 10. Therefore, the device can scrape and handle the material attached to the inner wall of the mixing barrel body 1 over a large area, and finally push it out, so as to facilitate the discharge of the device, save raw materials, and facilitate subsequent cleaning work, reduce the burden on the staff, and save production costs, so as to solve the problem that the horizontal setting of the mixing barrel in the reference patent results in that there are many positions inside that are staggered with the discharge port in the vertical space, so that the inner wall of the mixing barrel is prone to adhere to more raw materials and it is inconvenient to discharge the materials, a large amount of raw materials are wasted, and it is not convenient for subsequent cleaning work, which brings losses and troubles to the staff.
