[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Example

[0034] Reference Figure 1-5 The utility model provides an embodiment: a recrystallization purification device for solid materials, comprising a base 1, side plates 4 are fixedly arranged on both sides of the upper end surface of the base 1, a fixed plate 11 is fixedly arranged at the upper end of the two side plates 4 on the opposite side, a separation box 2 is fixedly arranged at the midpoint of the upper end surface of the base 1, a purification reactor 10 is embedded at the midpoint of the upper end surface of the fixed plate 11, a top cover 6 is threadedly sleeved on the upper end of the purification reactor 10, a stirring motor 7 is fixedly arranged at the midpoint of the upper end surface of the top cover 6, and an output shaft 22 is fixedly arranged at the output end, and a plurality of stirring rods 14 are fixedly arranged on the outer side of the output shaft 22; the solid material to be purified and the solvent liquid inside can be stirred and mixed by using the stirring motor 7, the output shaft 22 and the plurality of stirring rods 14;

[0035] A mesh frame 16 is fixedly provided at the outer side of the lower end surface of the top cover 6, and the mesh frame 16 can be quickly disassembled, cleaned and used, and the inner wall of the purification reactor 10 can be quickly cleaned after the mesh frame 16 is disassembled; electric heating plates 15 are embedded on both sides of the inner wall of the purification reactor 10, a connecting pipe 3 is fixedly provided at the midpoint of the lower end surface of the purification reactor 10, a micro motor 12 is fixedly provided on the front end surface of the connecting pipe 3 and a rotating shaft 17 is fixedly provided at the output end, a plurality of toggle plates 20 are fixedly provided on the outer side of the rotating shaft 17, a screening mechanism 18 is embedded on both sides of the inner wall of the separation box 2, the screening mechanism 18 includes a screen plate 1801, four springs 1802 and two bottom plates 1803, and a toggle mechanism 19 is embedded on the bottom end surface of the base 1, and the toggle mechanism 19 includes two toggle blocks 1901, a toggle rod 1902 and a toggle motor 1903.

[0036] When using the device, the solid material to be purified is injected along the feed pipe 8. A liquid inlet pipe 9 and an air inlet pipe 5 are fixedly arranged on one side and the other side of the upper end surface of the top cover 6, respectively. A feed pipe 8 is fixedly arranged on the side of the upper end surface of the top cover 6 close to the liquid inlet pipe 9. The lower end opening of the feed pipe 8 is located in the mesh frame 16. It can be seen that the injected solid material falls into the mesh frame 16. At this time, the solvent for purification is injected into the mesh frame 16 through the liquid inlet pipe 9, and the stirring motor 7 is started. The stirring motor 7 drives the output shaft 22 and a plurality of stirring rods 14 to stir and mix the solid material to be purified and the solvent liquid inside, and the electric heating plate 15 is turned on for heating to dissolve the material.

[0037] When the insoluble substances in the dissolved material are isolated in the mesh frame 16, after the reactor is concentrated to the desired system, inert gas is injected into the reactor through the air inlet pipe 5 during the heating process to mix with the system until it is fixed and precipitated, and then it can be discharged outward along the connecting pipe 3;

[0038] At this time, a valve 21 is arranged outside the connecting pipe 3, the rotating shaft 17 is rotatably arranged inside the connecting pipe 3, and a plurality of toggle plates 20 are arranged around the center of the rotating shaft 17 at equal intervals. It can be seen that when the valve 21 is opened, the micro motor 12 drives the rotating shaft 17 and the toggle plates 20 to rotate to intermittently toggle the fixed purified particles in the connecting pipe 3, so as to reduce the blockage of the connecting pipe 3;

[0039] After the fixed purified particles fall into the separation box 2, since the two bottom plates 1803 are fixedly arranged on both sides of the inner wall of the separation box 2, the four springs 1802 are fixedly arranged at the front and rear ends of the same bottom plate 1803, the screen plate 1801 is arranged on the upper ends of the four springs 1802, the screen plate 1801 and the two bottom plates 1803 are tilted backward, and the toggle rod 1902 is fixedly arranged at the output end of the toggle motor 1903, the two toggle blocks 190 1 are respectively fixedly sleeved on the upper end and the midpoint of the toggle rod 1902, and the two toggle blocks 1901 are respectively located at the midpoints of the lower ends of the two screen plates 1801. The two toggle blocks 1901 are both cylindrical, and the upper end surfaces are in the shape of inclined sections. It can be seen that when the particles fall on the screen plate 1801, the screen plate 1801 is repeatedly lifted and pushed by the toggle blocks 1901 with section-shaped upper surfaces to form repeated vibrations, thereby performing vibration screening effects on the purified particles;

[0040] Three receiving boxes 13 are movably arranged at the rear end of the separation box 2. The three receiving boxes 13 are respectively located at the upper, middle and lower ends. At this time, the purified particles after vibration screening will be collected in three different receiving boxes 13 to complete unified collection and processing.

[0041] Working principle: When in use, the solid material to be purified is injected into the mesh frame 16 through the feed pipe 8, and then the solvent is added for purification reaction. The insoluble matter is isolated in the mesh frame 16 so that it can be separated without filtering, and the solid particles precipitated after purification are discharged outward along the connecting pipe 2. A plurality of rotating shifting plates 20 are used in the connecting pipe 3 to perform intermittent material shifting effect to reduce internal blockage. At the same time, the purified particles that have fallen are screened and separated in multiple stages in the separation box 3, thereby reducing the secondary screening process after discharge.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
