DETAILED DESCRIPTION

[0021] See Figures 1 to 6 As shown, a feeding device for the production of a water reducing agent comprises a stirring tank 1 and a feeding box 2 installed on the top of the stirring tank 1. The top of the feeding box 2 is an open structure, and a feeding hopper 3 is installed on the top of the feeding box 2. When it is necessary to produce a water reducing agent, the raw materials of the water reducing agent can be poured into the feeding box 2 through the feeding hopper 3. A discharge trough 4 communicated with the stirring tank 1 is provided at the bottom of the feeding box 2. Two crushing rollers 5 are rotatably arranged inside the feeding box 2, and the two crushing rollers 5 are arranged opposite to each other. The inside of the feeding box 2 is inclined and symmetrically fixed with two inclined plates 19, and the two inclined plates 19 correspond to the feeding hopper 3. The raw materials entering the feeding box 2 can be crushed by the two crushing rollers 5, so that the lumps in the raw materials can be crushed. The raw materials can be aggregated through the two inclined plates 19 in the feeding box 2, so that the raw materials can be better crushed by the two crushing rollers 5.

[0022] A driving assembly 6 for driving the crushing rollers 5 to rotate is arranged outside the feeding box 2. When the raw materials need to be crushed by the crushing rollers 5, the driving assembly 6 can be started, and the driving assembly 6 drives the two crushing rollers 5 to rotate in opposite directions to achieve the crushing work.

[0023] See Figure 3-4As shown, the driving assembly 6 includes two gears 11 and a driving motor 12. One end of the two crushing rollers 5 passes through the feeding box 2 and is fixed with the two gears 11. The two gears 11 are meshed with each other. The driving motor 12 is installed on the outer wall of the feeding box 2. The driving motor 12 and the gear 11 are arranged opposite to each other. The output shaft of the driving motor 12 passes through the outer wall of the feeding box 2. The output shaft of the driving motor 12 is fixedly connected to one side of the crushing roller 5. When it is necessary to drive the crushing roller 5 to rotate, the driving motor 12 can be started, and the crushing roller 5 on one side is driven to rotate by the output shaft of the driving motor 12. During the rotation, the crushing roller 5 will drive the gear 11 fixed on the outside thereof to rotate. The rotation of the gear 11 on one side can realize the rotation of the gear 11 meshed with the other side. The rotation of the two gears 11 realizes the rotation of the two crushing rollers 5.

[0024] See Figure 2 As shown, the raw materials after the crushing process will pass through the discharge trough 4 at the bottom and enter the stirring tank 1 for processing. A driving motor 27 is also installed on the top of the stirring tank 1. A connecting rod 8 is installed on the output shaft of the driving motor 27. One end of the connecting rod 8 passes through the stirring tank 1 and is installed with a stirring member 9. The stirring member 9 is rotatably arranged in the stirring tank 1. When the raw materials enter the stirring tank 1, the driving motor 27 can be started, and the connecting rod 8 can be driven to rotate through the output shaft of the driving motor 27. The stirring member 9 can be driven to rotate through the connecting rod 8. The stirring member 9 can stir and mix the raw materials entering the stirring tank 1.

[0025] See Figure 2 and 5 As shown, the stirring member 9 includes a stirring rod 13, a plurality of stirring rods 14 and a plurality of connecting rods 15. The stirring rod 13 is fixed at the bottom of the connecting rod 8, and each connecting rod 15 is fixed on the bottom side wall of the stirring rod 13. The connecting rod 15 is arranged in an inclined shape. The stirring rod 14 is fixed at the end of the connecting rod 15 away from the stirring rod 13. The stirring rod 14 corresponds to the bottom side wall of the stirring tank 1. The connecting rod 8 will drive the stirring rod 13 to rotate during the rotation process, and the stirring rod 13 will drive each connecting rod 15 to rotate. The rotation of the stirring rod 14 is realized through the connecting rod 15, the overall stirring of the raw materials is realized through the stirring rod 13, and the stirring of the bottom of the stirring tank 1 is realized through the stirring rod 14, thereby further improving the stirring efficiency of the raw materials.

[0026] See Figure 2 and 6 As shown, the stirring member 9 is also provided with a screening component 10 for further screening the raw materials. When the raw materials enter the stirring tank 1, they will first pass through the screening component 10 to further screen the raw materials and remove the raw materials that have not been completely crushed.

[0027] The screening assembly 10 includes a screen 16 and a plurality of scraper plates 17. The screen 16 is mounted on the top side wall of the stirring rod 13. The screen 16 is connected to the stirring rod 13 through a bearing so that the stirring rod 13 does not interfere with the screen 16 when rotating. Each scraper plate 17 is fixed on the side wall of the stirring rod 13. The scraper plate 17 is arranged in an inclined shape. The scraper plate 17 is located above the screen 16 and the bottom of the scraper plate 17 is in contact with the screen 16. An inclined plate 18 is installed on the top side wall of the stirring tank 1. The inclined plate 18 corresponds to the discharge trough 4. When the raw material enters the stirring tank 1 through the discharge trough 4, it can be installed with the inclined plate 18. Plate 18 allows the raw materials to fall to the middle part of the mixing tank 1, preventing the raw materials from adhering to the inner wall when entering the mixing tank 1 directly through the discharge chute 4, which is not conducive to the mixing of the raw materials and is likely to cause waste. After the raw materials enter the mixing tank 1, they will first fall on the screen 16. At this time, the stirring rod 13 will be indirectly driven to rotate through the driving motor 2 7, and the stirring rod 13 will drive the scraper plates 17 to rotate together. The scraper plates 17 will scrape on the screen 16 when rotating. The scraping of the scraper plates 17 makes it easier for the screen 16 to screen the materials on the screen 16 more quickly, thereby improving production efficiency.

[0028] Working principle: When it is necessary to produce the water reducer, the raw materials for producing the water reducer can be first put into the mixing tank 1 through the feeding box 2 on the top of the mixing tank 1. The raw materials entering the feeding box 2 will be crushed by two crushing rollers 5, so that the lumps in the raw materials can be crushed, which is convenient for the subsequent crushing of the raw materials after entering the mixing tank 1. The two crushing rollers 5 are rotated by the driving component 6.

[0029] After being crushed, each raw material will enter the mixing tank 1 through the discharge chute 4. After entering the mixing tank 1, the raw material will fall onto the screen 16 of the screening component 10. The screen 16 can be used to perform secondary filtration of the raw material, thereby filtering out some small agglomerates of the raw material that cannot be crushed by the two crushing rollers 5, thereby ensuring that the raw materials entering the bottom of the mixing tank 1 are in a powdery structure, which is convenient for subsequent stirring and mixing.

[0030] The raw materials after two treatments will enter the bottom of the mixing tank 1 for subsequent production work. In order to improve the mixing efficiency of the raw materials, a stirring member 9 is installed in the mixing tank 1. The stirring member 9 improves the mixing efficiency of the raw materials. The raw materials are quickly mixed through the rotation of the stirring rod 13, the connecting rod 15 and the stirring rod 14.

[0031] When the stirring rod 13 is rotating, it will also drive the scraper plates 17 to rotate. When the scraper plates 17 are rotating, they will scrape on the screen 16. The scraping of the scraper plates 17 makes it easier for the screen 16 to screen the materials on the screen 16 more quickly, thereby improving production efficiency. In the process of the scraper plates 17, some of the agglomerated raw materials can be crushed so that these raw materials can pass through the screening of the screen 16, thereby improving the utilization rate of the raw materials.
