[0012] Further preferably, the stirring device also includes a second scraping assembly arranged on the stirring shaft, the second scraping assembly includes a second operating rod inserted into the tube cavity of the stirring shaft, and a second spring sleeved on the stirring shaft, the top end of the second operating rod passes through the top of the stirring shaft and is connected to the second spring, the end of the first operating rod passing through the tube cavity of the stirring shaft is provided with a top seat, and a top seat is fixed on the second operating rod, the top seat and the top seat are adjacent, and the top seat is provided with an inclined surface opposite to the top seat.

When the pedal seat rotates along the guide groove to contact the arc surface of the pressure seat, it will be squeezed by the arc surface of the pressure seat, so that the first operating rod retreats along the stirring rod, and the first spring is compressed and shortened. When the pedal seat rotates along the guide groove to separate from the pressure seat, the first spring elasticity becomes longer, and the first operating rod drives all the scrapers to move back and forth along the outer cylindrical surface of the stirring rod. The position changes of these scrapers on the stirring rod can reduce the residue of the prepared reactants on the stirring rod. Since the first spring is still sleeved on the stirring rod and the first spring can stretch and retract, it can also reduce the residue of the prepared reactants on the stirring rod. After the prepared reactants are mixed, when the stirring shaft drives the stirring rod to idle, the above-mentioned transmission relationship can better prevent the residue from adhering to the stirring rod;

[0018] In addition, when the first operating rod retracts along the stirring rod, the top seat at the inner end will squeeze the pushed seat. Since the pushed seat has an inclined surface, when the top seat hits the inclined surface, the pushed seat will lift up with the second operating rod. When the first operating rod retracts in the opposite direction along the stirring rod, the top seat leaves the pushed seat, and the pushed seat brings the second operating rod down, and the second operating rod brings the second spring down. The lifting and lowering action of the second spring on the stirring shaft can reduce the residue of the prepared reactants on the stirring shaft. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0028] In one embodiment, Figure 1-Figure 7 As shown: This embodiment provides a preparation process of selenium-rich salt, comprising the following steps:

[0029] S1. Select samples for random inspection from sodium chloride, tricalcium phosphate, magnesium carbonate, potassium chloride, potassium iodate, ferrous lactate, zinc lactate, sodium selenite, and manganese sulfate. After the random inspection quality is qualified, add them into a stirring device according to specific gravity from the above materials, mix salt water into the stirring device according to specific gravity, and stir to react to obtain salt water to prepare a reactant;

[0030] S2, adding the antithrombotic agent into the stirring device according to specific gravity, and obtaining new saline to prepare the reactant after stirring and reacting;

[0031] S3, mixing the salted selenium-enriched Cardamine with edible salt evenly to obtain a final brine to prepare a reactant;

[0032] S4, turning on the stirring device, discharging the final salt water to prepare the reactant, obtaining selenium-rich edible salt crystals through distillation, and obtaining anti-thrombotic selenium-rich edible salt. The obtained edible salt contains anti-thrombotic preparation components, so it can soften blood and reduce thrombosis after consumption.

[0033] The stirring device comprises a stirring tank 1, a stirring shaft 2 is arranged in the stirring tank 1, a motor 3 connected to the stirring shaft 2 for upward transmission is fixed at the bottom of the stirring tank 1, and a stirring rod 4 extending in the radial direction of the stirring tank 1 is fixed on the stirring shaft 2;

[0034] The stirring device also includes a driving assembly 5 installed on the cavity wall of the stirring tank 1 and a first scraping assembly 6 arranged on the stirring rod 4. The driving assembly 5 includes an arc-shaped guide seat 8 welded on the cavity wall of the stirring tank 1. The guide seat 8 is provided with an arc-shaped guide groove 9 running through both ends, and a pressure seat 17 fixed in the guide groove 9; the free end of the stirring rod 4 extends into the guide groove 9, and rotates along the guide groove 9 during stirring; the first scraping assembly 6 includes a first operating rod 10 running through the stirring rod 4 and a scraping rod 11 fixed on the first operating rod 10, and the stirring A leakage groove 12 is opened on the mixing rod 4 along the length direction, and there are several scraper rods 11. Several scraper rods 11 are fixed on the first operating rod 10 along the length direction. Several scraper rods 11 extend outward from the leakage groove 12 and then bend on the mixing rod 4. A pedal seat 13 is fixed to one end of the first operating rod 10, and the pedal seat 13 extends into the guide groove 9. A push seat 14 is installed at the other end of the first operating rod 10. The push seat 14 is close to the mixing shaft 2 and slides in the leakage groove 12. The mixing rod 4 is sleeved with a first spring 15 elastically supported between the push seat 14 and the mixing shaft 2.

[0035] The stirring shaft 2 is a tube, and one end of the first operating rod 10 on which the push seat 14 is installed continues to extend and penetrate into the tube cavity of the stirring shaft 2 .

[0036] like Figure 6 , Figure 7 As shown, the opening of the drain groove 12 faces downward. After the stirring work is completed, in order to prevent the prepared reactants from remaining in the drain groove 12, the scraper rod 11 is bent downward from the drain groove 12 and then bent upward on the stirring rod 4. When these scraper rods 11 change their linear positions left and right on the stirring rod 4, they can scrape and process the residues attached to the stirring rod 4.

[0037] In order to prevent residues from staying on the stirring shaft 2 after stirring, the stirring device also includes a second scraping component 7 arranged on the stirring shaft 2. The second scraping component 7 includes a second operating rod 16 inserted into the tubular cavity of the stirring shaft 2, and a second spring 18 sleeved on the stirring shaft 2. The top end of the second operating rod 16 passes through the top of the stirring shaft 2 and is connected to the second spring 18. A top seat 19 is provided at one end of the first operating rod 10 that passes through the tubular cavity of the stirring shaft 2. A top seat 20 is fixed on the second operating rod 16. The top seat 19 and the top seat 20 are adjacent to each other, and the top seat 20 is provided with an inclined surface 21 opposite to the top seat 19.

[0038] like Figure 4 , Figure 5As shown, there are several drive assemblies 5 with the same structure. Several drive assemblies 5 are fixed on the cavity wall of the stirring tank 1 in a circular array, and two adjacent drive assemblies 5 are arranged up and down in sequence. The number of stirring rods 4 is consistent with the number of drive assemblies 5. Each drive assembly 5 is provided with a stirring rod 4, and each stirring rod 4 is provided with a set of first scraping assemblies 6 corresponding to the drive assembly 5 to improve the cleaning efficiency of the residue. The purpose of arranging these stirring rods 4 up and down is to distribute them at different depths in the preparation of reactants, so as to improve the mixing efficiency when preparing reactants.

[0039] After the prepared reactants and salt water are injected into the stirring tank 1 and stirred by the stirring rod 4, they are discharged outwardly through the discharge pipe 25. However, a large amount of prepared reactants will still remain on the stirring rod 4 and the stirring shaft 2. However, when the stirring rod 4 in the present invention rotates, it will not only mix the prepared reactants evenly, but also rotate with the first operating rod 10. The first operating rod 10 will rotate with the pedal seat 13 at the end. When the pedal seat 13 rotates along the guide groove 9 to contact the arc surface of the pressure seat 17, it will be squeezed by the arc surface of the pressure seat 17, so that the first operating rod 10 The first spring 15 is compressed and shortened when the pedal 13 is rotated along the guide groove 9 to separate from the pressure seat 17, and the first spring 15 elastically lengthens, and the first operating rod 10 drives all the scrapers 11 to move back and forth along the outer surface of the stirring rod 4. The position changes of these scrapers 11 on the stirring rod 4 can reduce the residue of the prepared reactants on the stirring rod 4. Since the first spring 15 is still sleeved on the stirring rod 4 and the first spring 15 can stretch and retract, it can also reduce the residue of the prepared reactants on the stirring rod 4. After the prepared reactants are mixed, when the stirring shaft 2 drives the stirring rod 4 to idle, the above transmission relationship can better prevent the residue from adhering to the stirring rod 4;

[0040] In addition to making the residue on the stirring rod 4 fall off downward and reducing the adhesion of the residue on the stirring rod 4, the use of idling also has the following technical effects: when the first operating rod 10 rotates with the pedal seat 13 to contact the arc surface of the pressure seat 17, and causes the inner end of the first operating rod 10 to enter the tube cavity of the stirring shaft 2, in addition to using the push seat 14 to squeeze the first spring 15 for compression, and in addition to making all the scraper rods 11 move linearly along the outer cylindrical surface of the stirring rod 4, the inner end of the first operating rod 10 is also used to push the top seat 19 inward, so that the top seat 19 squeezes the top seat 20 in the radial direction of the stirring shaft 2. The seat 20 is provided with an inclined surface 21 facing the seat 19, so when the seat 20 is pressed against the inclined surface 21, the inclined surface 21 will be pressed, and the seat 20 will lift the second operating rod 16; on the contrary, when the pedal seat 13 at the outer end of the first operating rod 10 rotates to separate from the pressure seat 17 in an arc shape, the first spring 15 releases its length, and uses the push seat 14 to push the first operating rod 10 to move in a straight line in the opposite direction. At this time, the first operating rod 10 will not only move in a straight line in the opposite direction along the stirring rod 4, but also take the seat 19 away from the inclined surface 21. At this time, the pressure on the seat 20 disappears, and the seat 20 will descend with the second operating rod 16. The thrust generated by the action of the first operating rod 10 is transmitted to the second operating rod 16, so that the second operating rod 16 descends with the second spring 18, and the lifting action of the second spring 18 on the stirring shaft 2 can also reduce the residual of the prepared reactant on the stirring shaft 2.

[0041] In summary, the stirring tank 1 cannot improve the stirring efficiency by utilizing the stirring rods 4 distributed at different positions when in use, and after use, the stirring tank 1 can also be idling to reduce the residue of the prepared reactants on the stirring shaft 2 and the stirring rod 4.

[0042] like Figure 2 , Figure 4 As shown, the bottom of the mixing tank 1 is a guide surface 24, which is inclined downward in the direction of the second spring 18. A discharge pipe 25 is connected to the bottom of the mixing tank 1, and the top inner end of the discharge pipe 25 is close to the second spring 18. The discharge pipe 25 is provided with a valve, and when the valve is opened, the prepared reactants in the mixing tank 1 are drained, and the residues falling off the stirring rod 4 and the stirring shaft 2 can also flow into the discharge pipe 25 along the inclined surface of the bottom of the mixing tank 1, and finally discharged outward from the discharge pipe 25.

[0043] like Figure 4 As shown, the top surface of the guide seat 8 is provided with a rounded surface 22 which is gradually inclined downward, and a plurality of leak holes 23 are opened downward from the top surface of the guide seat 8, and the plurality of leak holes 23 are evenly distributed along the arc profile of the guide seat 8. When some residues fall on the guide seat 8, they will be discharged downward through the leak holes 23 or the arc profile, so as to prevent the cleaned residues from being attached to the guide seat 8 again.

[0044] The above orientation designations do not represent the specific orientations of the components in this implementation scheme. This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field. This is hereby explained.

[0045] The specific implementation methods described above further describe the invention purpose, technical solutions, and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the protection scope of the present invention. It is particularly pointed out that for those skilled in the art, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
