DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A three-dimensional view of the main structure of the reaction tank with grinding and stirring functions provided by the utility model; Figure 2 for Figure 1 A top view of Figure 3 for Figure 1 Partial structural plan view.

[0025] In the specific implementation process, Figure 1-Figure 3 As shown, it includes a tank body 1 with multiple supporting legs 2 fixed at the bottom, a discharge pipe 3 is arranged at the bottom of the tank body 1, and a material valve 4 is installed at the discharge pipe 3. After the reaction is completed, the material can be discharged by opening the material valve 4. Two stirring shafts 5 are movably arranged inside the tank body 1, one of the stirring shafts 5 is installed with a plurality of first stirring blades 6, and the other stirring shaft 5 is installed with a plurality of second stirring blades 7. The first stirring blades 6 and the second stirring blades 7 are staggered from top to bottom to avoid the first stirring blades 6 and the second stirring blades 7 from colliding when the two stirring shafts 5 rotate in opposite directions at the same time. By arranging a plurality of first stirring blades 6 and a plurality of second stirring blades 7, the added solid material and liquid material are fully stirred.

[0026] A crushing box 8 is connected to the top of the tank body 1, and two crushing rollers 9 are movably arranged inside the crushing box 8. When the reaction tank is in use, the staff can open the closing cover 21 and then add the material to be added into the crushing box 8. Under the action of the two crushing rollers 9, the larger particles in the material can be further crushed, thereby improving the mixing effect.

[0027] A transmission worm gear 10 is installed on the top of the two stirring shafts 5, and two first limit seats 11 and two second limit seats 12 are installed at intervals on the top of the tank body 1. A transmission worm 13 is movably arranged between the first limit seat 11 and the second limit seat 12 through a bearing. The two transmission worms 13 are respectively meshed with the two transmission worm wheels 10, and the threads on the two transmission worms 13 are in opposite directions. A first installation shaft 14 and a second installation shaft 15 are movably arranged between the two second limit seats 12, and both ends of the first installation shaft 14 are fixedly connected to the two transmission worms 13 respectively. A motor 23 is installed on one side of the tank body 1, and the output end of the motor 23 is connected to one of the transmission worms 13 through a coupling.

[0028] A first gear 16 is installed on the first installation shaft 14, and a second gear 17 is installed on the second installation shaft 15. The first gear 16 is meshed with the second gear 17. One end of the second installation shaft 15 passes through the second limit seat 12 and is installed with a third gear 18. A driving shaft 19 is fixed to one end of the two crushing rollers 9. A fourth gear 20 is installed on the two driving shafts 19. The two fourth gears 20 are meshed with each other, and one of the fourth gears 20 is meshed with the third gear 18. When the stirring shaft 5 rotates, the power of the motor 23 can be transmitted to the two crushing rollers 9 under the transmission action of the first gear 16, the second gear 17, the third gear 18 and the fourth gear 20, so as to achieve the effect of crushing the material. The number of teeth of the second gear 17 is greater than that of the first gear 16, and the number of teeth of the fourth gear 20 is greater than that of the third gear 18, which can reduce the power output by the motor 23.

[0029] Working principle of the utility model: when the reaction tank is in use, the staff can open the closed cover 21, and then add the material to be processed into the crushing box 8. Under the action of the two crushing rollers 9, the larger particles in the material can be further crushed, thereby improving the mixing effect. By setting a plurality of first stirring blades 6 and a plurality of second stirring blades 7, the added solid material and liquid material are fully stirred. In summary, the reaction tank can improve the quality of the manufactured emulsion, reduce the generation of waste products, make the reaction more complete, save raw materials, and improve the purity of the produced product;

[0030] The starting motor 23 can drive the two transmission worms 13 to rotate simultaneously. Under the transmission action of the transmission worm 13 and the transmission worm wheel 10, the two stirring shafts 5 rotate in opposite directions at the same time. When the stirring shafts 5 rotate, the power can be transmitted to the two crushing rollers 9 under the transmission action of the first gear 16, the second gear 17, the third gear 18 and the fourth gear 20, so as to achieve the effect of crushing the materials. The number of teeth of the second gear 17 is greater than that of the first gear 16, and the number of teeth of the fourth gear 20 is greater than that of the third gear 18, which can reduce the power output by the motor 23.

[0031] During stirring, the sealing cover 22 is closed. By setting the pressure relief valve 22, when the pressure in the tank body 1 exceeds the set pressure of the pressure relief valve, the pressure relief valve is automatically opened to ensure that the medium pressure in the equipment and pipelines is below the set pressure, thereby protecting the equipment and pipelines and preventing accidents, so that the tank body 1 has a better self-protection effect.
