[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] A calcium carbonate impurity removal device includes a sorting box 1, a trapezoidal plate 2 is fixedly installed on the inner wall of one side of the sorting box 1, a through groove 3 is opened on the top of the trapezoidal plate 2, a screen 4 is fixedly embedded in the through groove 3, an adsorption cover 5 is provided inside the sorting box 1, a negative pressure pipe 6 is fixedly connected to one side wall of the adsorption cover 5, one end of the negative pressure pipe 6 passes through the sorting box 1 and is fixedly connected to a refining barrel 7, a water inlet pipe 8 is fixedly connected to one side wall of the refining barrel 7, and a stirring component 9 is provided inside the refining barrel 7. The utility model plays a role in separating sand, quartz and other particles in the calcium carbonate powder by setting the sorting box 1, the trapezoidal plate 2, the through groove 3 and the screen 4. The calcium carbonate powder after screening is adsorbed and collected by arranging the adsorption cover 5, the negative pressure pipe 6 and the vacuum pump 12. The calcium carbonate powder can be pumped into the interior of the refining barrel 7. A proper amount of water is injected into the interior of the refining barrel 7 through the water inlet pipe 8 to dissolve the soluble impurities in the calcium carbonate powder. The stirring component 9 is provided to accelerate the dissolution rate of the soluble impurities. The magnet 11 is provided on the stirring paddle 903 to adsorb and collect the fine iron sand impurities in the calcium carbonate powder. The mixture of the calcium carbonate powder and water after the treatment is completed can be discharged from the discharge hopper and then dried.

[0024] The stirring assembly 9 includes a rotating rod 901, the top of which is rotatably mounted on the inner top of the refining barrel 7. The top of the rotating rod 901 passes through the refining barrel 7 and is connected to a drive motor 902. A plurality of stirring paddles 903 are fixedly mounted in a circular array on the outer wall of the rotating rod 901.

[0025] Specifically, the output shaft of the driving motor 902 can drive the rotating rod 901 to rotate, thereby driving the plurality of stirring paddles 903 to rotate, thereby stirring the calcium carbonate powder and water, thereby achieving the effect of accelerating the rapid dissolution of soluble impurities in the calcium carbonate powder;

[0026] The side wall of the stirring paddle 903 is provided with a plurality of through holes 10. The provision of the through holes 10 can further improve the stirring and dissolution efficiency of the soluble impurities. Magnets 11 are fixedly mounted on the top and bottom of the stirring paddle 903. When the stirring paddle 903 rotates, the magnets 11 can adsorb and collect iron sand impurities in the calcium carbonate powder, thereby effectively removing the iron sand impurities in the calcium carbonate powder and further improving the production quality of the calcium carbonate powder.

[0027] The driving motor 902 is fixedly mounted on the top of the refining barrel 7, and one end of the output shaft of the driving motor 902 is fixedly connected to the top of the rotating rod 901. The driving motor 902 is configured as a stepping motor. An important characteristic of the stepping motor is that its angular displacement or linear displacement is proportional to the number of input pulses, which means that the rotation angle or movement distance of the plurality of groups of stirring paddles 903 can be precisely controlled, thereby achieving precise stirring and impurity removal of the calcium carbonate and water mixture. In addition, the stepping motor has a fast start-stop and reverse response capability, which is very important for the calcium carbonate impurity removal device because it may be necessary to frequently change the rotation direction or speed of the plurality of groups of stirring paddles 903 to adapt to different impurity removal requirements.

[0028] A vacuum pump 12 is fixedly installed on the top of the refining barrel 7, and the bottom end of the vacuum pump 12 is connected to the interior of the refining barrel 7. The vacuum pump 12 continuously sucks the gas, so that the gas inside the refining barrel 7 enters the interior of the vacuum pump 12, and then discharges the gas, thereby providing a negative pressure environment for the interior of the refining barrel 7. At the same time, the air inside the negative pressure pipe 6 is also sucked away by the vacuum pump 12, thereby forming a negative pressure environment, and then the adsorption cover 5 can be used to adsorb the calcium carbonate powder that has been screened on the trapezoidal plate 2, and then enter the interior of the refining barrel 7 through the negative pressure pipe 6;

[0029] A discharge hopper 13 is fixedly embedded at the bottom of the refining barrel 7, and a valve is provided on the outer wall of the discharge hopper 13. After the stirring assembly 9 stirs the mixture of calcium carbonate powder and water for a certain period of time and the soluble impurities in the calcium carbonate powder are completely dissolved, the valve can be opened to discharge the material (the mixture of calcium carbonate powder and water) together, and then the calcium carbonate powder is dried by a drying device (not shown in the figure);

[0030] The top of the sorting box 1 is fixedly connected to a feed hopper 14. By setting the feed hopper 14, the staff can inject the calcium carbonate to be treated into the interior of the sorting box 1 through the feed hopper 14. The bottom of the sorting box 1 is fixedly connected to a drop pipe 15. The sieved sand, quartz and other granular impurities will be discharged through the drop pipe 15.

[0031] It also includes a vibration motor 16, which is fixedly installed on the inner wall of one side of the trapezoidal plate 2. By setting the vibration motor 16, the trapezoidal plate 2 can be driven to vibrate, thereby improving the efficiency of the screen 4 in screening the calcium carbonate powder.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
