[0002] High-purity strontium chloride (SrCl2) plays an important role in the field of oral care, mainly used for preventing dental caries, relieving tooth sensitivity, and promoting enamel remineralization.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0055] Referring to Figures 1-4 , the present invention provides a technical solution: a high-purity strontium chloride preparation device for oral care, including:

[0058] Fixed disk 4, fixed on the upper end face of the inner chamber body 3;

[0059] Atomization assembly 5, fixed at the axial center position of the fixed disk 4;

[0060] Hose inlet 6, starting on the outer chamber body 2 and communicating with the atomization assembly 5;

[0061] Discharge port 7, one end fixed on the lower end face of the inner chamber body 3, and the other end connected to a conveying port 8, and the conveying port 8 is for vacuum conveying;

[0062] Heating assembly, fixed on the outer chamber body 2 and the inner chamber body 3, and it includes a blocking port 9, a first heating port 10, a retention chamber 11 and a second heating port 12. The blocking port 9 is opened on the fixed disk 4. The first heating ports 10 are configured in multiple numbers, all inclined and fixed on the outer chamber body 2 and the inner chamber body 3, and are synchronously heated by an external heating device one through pipelines. The retention chamber 11 is fixed inside the inner chamber body 3. The second heating ports 12 are configured in multiple numbers, all inclined and fixed on the inner chamber body 3, and are synchronously heated by an external heating device two through pipelines.

[0063] In this embodiment, the hot gas direction of the blocking port 9 is vertically downward. The inclination directions of the first heating ports 10 and the second heating ports 12 both face the retention chamber 11. Multiple retention holes are opened on the retention chamber 11, and the hot gas pressure of the second heating ports 12 is less than the hot gas pressure of the first heating ports 10.

[0064] That is to say, when the atomization assembly 5 performs atomization, the intake air vertically downward through the blocking port 9 can prevent the atomized liquid droplets from hitting the inner wall of the inner chamber body, avoiding the effect of poor droplet uniformity. The retention holes of the retention chamber 11 can make the hot gas more concentrated, and the intake air pressure of the second heating ports 12 being less than the intake air pressure of the first heating ports 10 can reduce the falling speed of the droplets, thereby improving the drying effect.

[0065] In this embodiment, the atomization assembly 5 includes:

[0066] Centrifugal motor 51, fixed on the fixed disk 4;

[0067] Fixing member 52, fixed on the lower end face of the centrifugal motor 51, and two annular grooves 521 are opened inside it;

[0071] The elastic wall 56 is fixed to the centrifugal disk 55;

[0072] The adjusting assembly 57 is installed on the centrifugal disk 55 and the fixing member 52.

[0073] That is to say, the angle of the elastic wall 56 can be adjusted through the adjusting assembly 57, so as to increase the linear velocity of the strontium chloride solution being thrown out, adjust the particle size of the atomized droplets, and meet the requirements of various particle sizes.

[0074] As a preferred embodiment, the adjusting assembly 57 includes:

[0075] The adjusting column 571 is rotatably arranged in the centrifugal disk 55;

[0076] The adjusting disk 572 is fixed to the lower end surface of the adjusting column 571;

[0077] A plurality of pull rods 573 are provided, one end of each pull rod is hinged to the adjusting disk 572, and the other end is spherically hinged with a sliding column 574;

[0083] Among them, by arranging the support column 575 inside the elastic wall 56, the elastic wall 56 can be supported to prevent large deformation of the elastic wall 56 during centrifugation. When adjusting the angle of the elastic wall 56, the adjusting column 571 is disengaged from the limited position through the limiting component 579. Then, the adjusting column 571 is rotated by the driving component, and the adjusting disc 572 pulls the pulling rod 573, thereby driving the support column 575 to rotate, completing the angle adjustment of the elastic wall 56. After the adjustment is completed, the adjusting column 571 is limited by the limiting component 579 to rotate synchronously with the centrifugal disc 55.

[0084] As a preferred embodiment, magnets are fixed in each of the plurality of limiting holes 576.

[0090] Among them, during adjustment, the first telescopic motor 5781 drives the first push ring 5782 to slide, so that the first push ring 5782 is inserted into the first push groove 5784, driving the driving rack 5783 to slide, thereby rotating the adjusting column 571. Then, it is limited by the limiting component 579. Then, the first telescopic motor 5781 drives the first push ring 5782 to slide, so that the first push ring 5782 disengages from the first push groove 5784.

[0091] As a preferred embodiment, the limiting component 579 includes:

[0092] Two telescopic motors 5791 are symmetrically fixed inside the fixing member 52;

[0093] A second push ring 5792 is slidably arranged inside the fixing member 52 and is connected to the output end of the telescopic motor 5791;

[0094] A limiting column 5793 is slidably arranged inside the boss, corresponding to the limiting hole 576, and an attracting member is fixed at one end of the limiting column 5793 close to the limiting hole 576;

[0095] The pushing groove two 5794 is opened at one end of the limiting column 5793 away from the suction attachment;

[0096] The reset disk 5795 is fixed on the limiting column 5793, and a second spring is arranged between the reset disk and the inner wall of the boss.

[0097] Among them, when disengaging the limit, the telescopic motor two 5791 drives the pushing ring two 5792 to slide, so that the pushing ring two 5792 is inserted into the pushing groove two 5794, driving the limiting column 5793 to slide, so as to disengage from the limiting hole 576, facilitating the driving component 578 to drive the adjusting column 571. After the driving is completed, the telescopic motor two 5791 drives the pushing ring two 5792 to slide, so that the pushing ring two 5792 disengages from the pushing groove two 5794. At this time, the limiting column 5793 is reset by the second spring and adsorbed by the suction attachment and the magnet in the limiting hole 576 to improve the stability of the limit.

[0098] A preparation method of a high-purity strontium chloride preparation device for oral care includes the following steps:

[0099] S1. Raw material dissolution; Dissolve the strontium chloride raw material in deionized water to form a saturated solution;

[0100] S2. Solution filtration; Filter the saturated solution through a filtration device to remove insoluble impurities;

[0101] S3. Drying and crystallization; Atomize the solution through the atomizing component 5, and then dry and crystallize the atomized droplets through the heating component to form strontium chloride powder;

[0102] S4. Recrystallization; Dissolve the crystallized strontium chloride powder again, and recrystallize it again through the atomizing component 5 and the heating component to form high-purity strontium chloride powder;

[0103] That is to say, when performing drying and crystallization in S3 and S4, first, the adjusting component 57 in the atomizing component 5 can adjust the inclination angle of the elastic wall 56, change the linear velocity of the centrifugal throwing of the strontium chloride solution, so as to change the particle size of the atomized droplets, realizing the requirements of various particle sizes. And when heating and drying, the hot air can be more concentrated through the retention holes of the retention chamber 11, and the falling speed of the droplets can be reduced by the intake pressure of the second heating port 12 being less than the intake pressure of the first heating port 10, so as to improve the drying effect.
