[0021] As Figures 1 to 4 shown, the anti-precipitation device for concrete admixtures in this embodiment includes a bottom plate 1 and a mixing tank 2. The mixing tank 2 is installed at the upper end of the bottom plate 1 through a support rod. A treatment tank 3 is installed at the upper end of the bottom plate 1 on one side of the mixing tank 2. The upper ends of the treatment tank 3 and the mixing tank 2 can be disassembled for easy cleaning and clearing. The treatment tank 3 is used to treat the water added to the inside of the mixing tank 2. A mixing component is provided inside the mixing tank 2, and the mixing component is used to fully stir and mix the concrete and the admixture. A stirring component 5 is provided inside the treatment tank 3. The stirring component 5 is a common stirring device, mainly used to fuse water and a chemical solvent to produce a reaction. An injection pipe 6 is installed at the top of the treatment tank 3, and a solvent tank 7 is installed at the upper end of the injection pipe 6. A chemical solvent is placed inside the solvent tank 7. The chemical solvent is a softening agent or a chelating agent. The softening agent or the chelating agent can react chemically with calcium and magnesium ions in water to form insoluble substances, thereby preventing calcium and magnesium ions in water from precipitating with the admixture. A pump body 8 is installed at the upper end of the treatment tank 3 on one side of the solvent tank 7. Hoses 9 are installed at both the output end and the input end of the pump body 8. One end of each of the two hoses 9 is located inside the mixing tank 2 and the treatment tank 3 respectively. The pump body 8 adds the water treated inside the treatment tank 3 to the inside of the mixing tank 2 through the hoses 9. A control panel 10 is installed at the upper end of the bottom plate 1 in front of the treatment tank 3. The control panel 10 can control the mixing component at a fixed time to ensure the full mixing of the concrete and the admixture, and the control panel 10 can control each electrical component.
[0022] Specifically, the mixing component includes a rotating shaft 401, stirring rods 402, a stirring motor 403, a first gear 404, and a second gear 405. Three rotating shafts 401 are linearly arrayed and installed at the upper end of the mixing tank 2 through bearing parts. A first gear 404 is installed at the upper end of the middle rotating shaft 401, and second gears 405 are installed at the upper ends of the two side rotating shafts 401. The two second gears 405 are respectively meshed with the first gear 404. A number of stirring rods 402 are installed on the inner surface of the mixing tank 2 where the three rotating shafts 401 are located. Above the first gear 404, a fixing plate 11 is installed at the top of the mixing tank 2 through a support rod. A stirring motor 403 is installed at the upper end of the fixing plate 11. The output end of the stirring motor 403 is connected to the upper end of the first gear 404. The stirring motor 403 drives the first gear 404 to rotate, and the first gear 404 drives the two second gears 405 to rotate, thereby driving the stirring rods 402 on the surface of the rotating shaft 401 to stir the concrete and admixture. Moreover, the rotation directions of adjacent rotating shafts 401 are different, which can achieve the full mixing of the concrete and admixture.
[0023] Furthermore, a number of stirring rods 402 are arranged staggeredly. When the multiple stirring rods 402 are stirring, they will not collide with each other.
[0024] Furthermore, an addition port 12 is arranged on the surface of the mixing tank 2, a discharge pipe 13 is installed at the lower end of the mixing tank 2, and a stirring blade 14 is installed at the lower end of the middle rotating shaft 401. The lower end of the stirring blade 14 extends into the discharge pipe 13. When the concrete is not discharged, the stirring blade 14 rotates to transfer the concrete inside the discharge pipe 13, realizing the mixing of the concrete and admixture inside the discharge pipe 13. When the concrete is discharged, the stirring blade 14 rotates in the reverse direction, and the stirring blade 14 conveys the concrete to avoid the blockage of the discharge pipe 13 by the concrete.
[0025] Furthermore, a scale 15 is provided on the surface of the solvent tank 7, and a control valve 16 is installed on the surface of the injection pipe 6. By using the control valve 16 to control the on-off of the injection pipe 6, it is convenient to control the capacity of the chemical solvent added into the treatment tank 3.
[0026] Even further, a filter block 17 is installed at one end of the hose 9 inside the treatment tank 3, and a floating block 18 is installed on the surface of the hose 9 above the filter block 17. The filter block 17 is used to filter the insoluble substances after the reaction between the chemical solvent and calcium and magnesium ions in the water, preventing the insoluble substances from entering the mixing tank 2. The floating block 18 makes the hose 9 extend into the water by a certain part, avoiding the contact between the lower end of the hose 9 and the sediment of the insoluble substances.
[0027] The usage method of this embodiment is as follows: When using this anti-settling device for concrete admixtures, the device is connected to the power supply and controlled by the control panel 10. Water is added into the treatment tank 3, and the chemical solvent in the solvent tank 7 is added into the treatment tank 3. The calcium and magnesium ions in the chemical solvent and water form insoluble substances. At the same time, the concrete raw materials and admixtures are added into the mixing tank 2 through the addition port 12. The pump body 8 discharges the treated water into the mixing tank 2 through the hose 9. Then, the stirring motor 403 drives the first gear 404 to rotate, and the first gear 404 drives the two second gears 405 to rotate, thereby driving the stirring rod 402 on the surface of the rotating shaft 401 to fully stir the concrete and the admixture. Moreover, the rotation directions of adjacent rotating shafts 401 are different, which helps in the mixing of the concrete and the admixture. The control panel 10 controls the rotation of the stirring motor 403 for a certain period of time to achieve the full stirring of the concrete and the admixture. When it is necessary to discharge the concrete, the stirring motor 403 drives the stirring blade 14 to rotate in the reverse direction, and the stirring blade 14 conveys the concrete, and the concrete is discharged from the discharge pipe 13.
[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
