[0004] However, considering that when the raw materials fall from the mixing area to the grinding area, the feeding operation is mainly completed by the way of direct and rapid introduction. However, the feeding speed of the raw materials is too fast, which often easily increases the load during the operation of the device and results in a short grinding time for the device to grind the raw materials. At the same time, the device will not have enough time to fully grind the raw materials, resulting in a reduction in grinding efficiency. Therefore, a mixing and grinding device for resistance reducing agents is proposed for the above problems. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0021] A device for mixing and grinding a resistance reducing agent, comprising a processing tank body 1. A driving motor 2 is fixedly installed at the middle position of the top end of the processing tank body 1. An upper hollow frustum 3 and a lower hollow frustum 4 are successively arranged in the processing tank body 1 from top to bottom. A grinding cone body 5 is movably installed at the middle position of the lower hollow frustum 4. Activity slots 6 are respectively opened on the left and right sides near the center position inside the lower hollow frustum 4. An auxiliary cone ring 7 is arranged in the depression of the upper hollow frustum 3. A telescopic sleeve 8 is fixedly connected to the bottom of the auxiliary cone ring 7. A material control retaining ring 9 is arranged at the bottom of the telescopic sleeve 8. Side clamping plates 10 are respectively fixedly connected to both sides of the material control retaining ring 9. Guide rods 11 are inserted at both sides of the side clamping plates 10. A telescopic rod 12 is fixedly installed at the bottom of the upper hollow frustum 3.
[0022] As Figure 1 and Figure 2 shown, a feeding square opening 15 is conductively arranged at the upper left position of the processing tank body 1. A blanking hopper 20 is connected to the bottom of the processing tank body 1. The outer shape of the blanking hopper 20 is arranged in an upper thick and lower narrow structure. When taking out the mixed and ground powder raw materials, the upper thick and lower narrow structure setting of the overall outer shape of the blanking hopper 20 will make the blanking operation more centralized. The output end of the driving motor 2 is fixedly connected to a driving main shaft 13. The driving main shaft 13 extends into the processing tank body 1 and is fixedly connected to the grinding cone body 5. Stirring support rods 14 are fixedly connected to the outside of the driving main shaft 13. The outer shape of the stirring support rods 14 is arranged in an "L" shape. The three groups of stirring support rods 14 are successively shortened from top to bottom. With this successive shortening setting of the three groups of stirring support rods 14, it can play a role in adapting to stir the granular raw materials inside the upper hollow frustum 3. The bottom of the lower hollow frustum 4 is fixedly connected to a lower bracket 16. The bottom of the lower bracket 16 is fixedly connected to a threaded cover frame 17. A porous sieve plate 18 is threadedly connected to the inside of the threaded cover frame 17. A sweeping brush 19 is arranged in a fitting manner on the top of the porous sieve plate 18. The sweeping brush 19 is fixedly connected to the driving main shaft 13. When the ground powder raw materials fall on the porous sieve plate 18, the setting of the porous sieve plate 18 mainly plays a role in sieving the qualified powder raw materials.
[0023] As Figure 2 , Figure 3 and Figure 4As shown, the upper hollow frustum 3 is arranged to gradually concave from top to bottom, the lower hollow frustum 4 is arranged to gradually concave from bottom to top, the material control retaining ring 9 is arranged at the concave part of the lower hollow frustum 4, the side clamping plate 10 is arranged inside the movable slot 6, the guide rod 11 is fixedly connected through the movable slot 6 and the lower hollow frustum 4, the movable end of the telescopic rod 12 extends into the movable slot 6 and is fixedly connected with the side clamping plate 10, the grinding cone body 5 and the material control retaining ring 9 are arranged opposite to each other in the up and down positions. The lower hollow frustum 4 is arranged to gradually concave from bottom to top, which will form a narrow grinding gap with the grinding cone body 5, so that the device can efficiently complete the grinding operation. And when the side clamping plate 10 realizes the up and down lifting adjustment, a set of guide rods 11 mainly play an auxiliary guiding role.
[0024] Working process: All the electric energy required when the device in the present utility model starts and runs comes from an external power source. When the resistance reducing agent mixing and grinding device needs to be used, as the granular raw materials for producing the resistance reducing agent are introduced into the interior of the processing tank 1 through the interior of the feeding square opening 15, and the device starts the driving motor 2 to drive the stirring support rods 14, the grinding cone body 5 and the sweeping brush 19 to rotate. First, the whole device will first carry out sufficient stirring and mixing treatment on the granular raw materials pre-falling into the mixing area through the three groups of stirring support rods 14 in the rotating state. After the granular raw materials are mixed and gradually slide down from the concave part of the upper hollow frustum 3, the whole device will effectively control the feeding speed of the granular raw materials through the material control structure composed of the auxiliary cone ring 7, the telescopic sleeve 8, the material control retaining ring 9, the side clamping plate 10, the guide rod 11 and the telescopic rod 12, so that the granular raw materials can be gradually fed into the grinding gap formed between the grinding cone body 5 and the lower hollow frustum 4 after the feeding speed is controlled, so that the device can fully grind the granular raw materials through the grinding cone body 5 in the rotating state. Then, after the ground powder raw materials fall along the edge position of the grinding cone body 5 to the porous sieve plate 18, the device will use the sweeping brush 19 to disturb the powder raw materials so that they can be evenly diffused in multiple directions above the porous sieve plate 18, so as to penetrate the microporous structure inside the porous sieve plate 18 to achieve uniform feeding. Finally, the well-mixed and ground powder raw materials will be taken out of the whole device through the interior of the feeding hopper 20, cooperating with the device to complete the corresponding mixing and grinding operation. And when it is necessary to control and adjust the falling speed of the granular raw materials, under the connection and limitation of the upper hollow frustum 3, the lower hollow frustum 4 and the movable slot 6, a set of telescopic rods 12 can be started at the same time to drive the left and right side clamping plates 10 and the material control retaining ring 9 to move up and down. While quickly changing the space size between the material control retaining ring 9 and the grinding cone body 5, it is also beneficial for the device to achieve the purpose of controlling the falling speed of the granular raw materials by changing the space size.
[0025] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model.
