[0004] The quick-setting agent production device in the above scheme can improve the production quality by setting up a multi-layer stirring component to stir the liquid alkali-free quick-setting agent in multiple layers.

[0005] Although this accelerator production device can improve product quality, the use of a mixing disc in the middle of the mixing tank results in residual material remaining on the mixing disc after discharge. When producing different proportions of accelerator, this residual material will mix with the new raw material, making it difficult to control the proportion of accelerator and easily leading to a decline in product quality.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] A mixer for producing liquid alkali-free quick-setting agents, such as Figures 1-5 As shown, the system includes a mixing tank 1, a support frame 2 fixedly connected to the mixing tank 1, a motor 3 fixedly connected to the support frame 2, a stirring shaft 4 fixedly connected to the output shaft of the motor 3, and several blades 5 fixedly connected to the stirring shaft 4. The support frame 2 and the stirring shaft 4 are equipped with reinforcing components for stirring the middle part of the mixing tank 1. When producing liquid alkali-free quick-setting agent, a specified amount of water can be added to the mixing tank 1 first, and then the motor 3 can be turned on to drive the stirring shaft 4 and the blades 5 on the stirring shaft 4 to rotate, while simultaneously driving the reinforcing components to operate. Then, a specified amount of aluminum sulfate can be added, and after it is completely dissolved, a specified amount of masterbatch can be added and stirred until it is completely dissolved. Finally, it can be taken out of the mixing tank 1. In this way, by setting up the reinforcing components, the middle part of the mixing tank 1 can be continuously stirred while avoiding raw material residue, and the stirring can be made more uniform and thorough, thereby improving the production quality.

[0025] like Figures 1-5 As shown, the reinforcing component includes two positioning frames 6 fixedly connected to the support frame 2, a sleeve 7 rotatably connected to the positioning frame 6, a sliding rod 8 slidably connected inside the sleeve 7, and several blades 9 fixedly connected to the sliding rod 8. The sleeve 7 and the stirring shaft 4 are provided with transmission components for driving the sleeve 7 to rotate, and the stirring shaft 4 and the sliding rod 8 are provided with driving components for driving the sliding rod 8 to slide. The transmission components include a gear 10 fixedly connected to the stirring shaft 4 and a gear 11 fixedly connected to the sleeve 7. The gear 10 and the gear 11 mesh with each other. The driving components include a undulating ring 12 fixedly connected to the stirring shaft 4, a positioning ring 13 slidably connected to the stirring tank 1, and a positioning rod 14 fixedly connected to the positioning ring 13. The sliding rod 8 is rotatably connected to the positioning ring 13. Two springs 15 are fixedly connected to the positioning ring 13. The other ends of the two springs 15 are fixedly connected to the positioning frame 6 on the same side. When the undulating ring 12 contacts the positioning rod 14, the springs 15 are in a stretched state.

[0026] like Figures 1-5 As shown, when mixing is required, motor 3 is turned on to drive the stirring shaft 4 and the first blade 5 on the stirring shaft 4 to rotate. When the stirring shaft 4 rotates, gear 10 drives gear 2 11 to rotate. At this time, sleeve 7, sliding rod 8 and third blade 18 will also rotate to stir. At the same time, the oscillating ring 12 will also rotate due to the rotation of the stirring shaft 4. When the positioning rod 14 contacts the uphill section of the oscillating ring 12, the sliding rod 8 will slide out from the sleeve 7 and drive the second blade 9 to rotate downward to stir. At this time, the spring 15 is in a stretched state. Then the positioning rod 14 will contact the downhill section of the oscillating ring 12. At this time, the spring 15 will start to return to the normal state, driving the sliding rod 8 to move to the bottom side of the sleeve 7 and driving the second blade 9 to rotate upward to stir. By repeating this process, the second blade 9 can move up and down during stirring, making the stirring more uniform and thorough, thereby improving the production quality.

[0027] like Figure 4 As shown, a cavity 16 is provided inside the blade 5, and several heating rods 17 are fixedly connected inside the cavity 16. The heating rods 17 can be turned on during stirring to raise the temperature of the liquid in the stirring tank 1, so that the raw materials in the tank can react more thoroughly, thereby improving the production quality.

[0028] like Figures 2-4 As shown, several blades 18 are fixedly connected to the end of the stirring shaft 4 away from the motor 3. The blades 18 are in contact with the bottom side of the mixing tank 1. When the motor 3 rotates, it will drive the stirring shaft 4 and the blades 18 to rotate, which can prevent solid raw materials from settling at the bottom of the mixing tank 1, making the mixing more uniform and thus improving the production quality.

[0029] like Figures 1-5 As shown, the mixing tank 1, mixing shaft 4, oscillating ring 12, positioning ring 13, sliding rod 8, blade 1 5, blade 2 9, and blade 3 18 are all made of steel lined with PP material. Since the pH of the liquid is ≥2.0 during mixing, the steel lined with PP material can prevent the parts in contact with the liquid from being corroded by the liquid, thereby improving the service life of the mixer.

[0030] Working principle: When producing liquid alkali-free quick-setting agent, first add the specified amount of water to the mixing tank 1, then turn on the heating rod 17 and the motor 3 to drive the mixing shaft 4 and the impellers 1-5 and 3-18 on the mixing shaft 4 to rotate. Then add the specified amount of aluminum sulfate. When the mixing shaft 4 rotates, gear 1-10 will drive gear 2-11 to rotate. At this time, the sleeve 7, sliding rod 8, and impeller 3-18 will also rotate to stir. At the same time, the oscillating ring 12 will also rotate due to the rotation of the mixing shaft 4. When the positioning rod 14 contacts the uphill section of the oscillating ring 12, the sliding rod 8 will slide out from the sleeve 7 and drive impeller 2-9 to rotate downwards to stir. At this time, the spring 15 is in a stretched state, and then the positioning rod 14 is in a stretched state. Position rod 14 will contact the downhill section of the undulating ring 12. At this time, spring 15 will start to return to its normal state, driving sliding rod 8 to move towards the bottom of sleeve 7 and driving blade 2 9 to rotate upward and stir. By repeating this process, blade 2 9 can move up and down during stirring, making the stirring more uniform and thorough. After it is completely dissolved, the specified amount of masterbatch is added and stirring is continued until it is completely dissolved. Finally, it can be taken out from the stirring tank 1. In this way, the middle part of the stirring tank 1 can be continuously stirred while avoiding raw material residue. The up and down movement of blade 2 9 during stirring can also make the stirring more uniform and thorough. In addition, the temperature of the liquid in the stirring tank 1 can be increased during stirring, making the reaction more thorough and thus improving the production quality.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
