[0040] The following is combined with Figure 1-5 The utility model is described in further detail.

[0041] Embodiment 1, refer to Figure 1-2 In order to solve the problem of limited stirring effect in the prior art, the utility model discloses a preparation device for high-purity bis(propyltriethoxysilane) disulfide.

[0042] The device assembly 100 includes a device body 101, a material discharge port 102 is provided below the device body 101, and a support leg 103 is connected to the lower outer side of the device body 101;

[0043] The stirring assembly 200 also includes a driving motor 201, which is located above the device body 101. A driving rod 202 is connected to the bottom of the driving motor 201, and the driving rod 202 drives the stirring block 203 to rotate, so as to stir and prepare the raw materials. The outer side of the driving rod 202 is connected to the stirring block 203, and the two sides of the stirring block 203 are connected to the guide blocks 205. The two sides of the guide block 205 are provided with diversion grooves 204. The guide block 205 is used to increase the stirring range, thereby improving the stirring effect.

[0044] The lower center of the device body 101 coincides with the center of the discharge port 102, and a feeding port and an inlet are provided on the upper side of the device body 101. The device body 101 and the support leg 103 are connected by hot melt connection. Different raw materials can be added separately through the inlet and the feeding port to ensure that they do not interfere with each other.

[0045] The driving motor 201 and the driving rod 202 are connected by a key connection. The stirring blocks 203 are evenly and equidistantly distributed on the outside of the driving rod 202. The driving rod 202 and the stirring block 203 rotate in an integrated manner. The driving rod 202 drives the stirring block 203 to rotate, thereby driving the raw materials to be stirred to achieve the preparation work.

[0046] The stirring block 203 is in an arc-shaped structure. The two sides of the stirring block 203 are symmetrically provided with guide blocks 205. The center of the guide block 205 is symmetrically provided with diversion grooves 204. The stirring block 203 cooperates with the guide block 205 to increase the stirring range of the stirring block 203 and improve the stirring effect.

[0047] The specific working principle is: first, sodium pyrosulfide aqueous solution and a small amount of phosphate are added to the inside of the device body 101 through the feed port and the feeding port, and mixed with the triethylamine inside the device body 101, and the switch of the driving motor 201 is turned on, so that the driving motor 201 drives the driving rod 202 to rotate, and the driving rod 202 drives the stirring block 203 to rotate. Because the stirring block 203 itself is an arc structure, the raw materials in the center are driven to move toward the outside during the stirring process, and the outside is squeezed to the central area. At the same time, the stirring block 203 drives the guide block 205 to rotate, thereby increasing the stirring range. The diverter trough 204 allows a part of the raw materials to stay in place, while the newly filled raw materials are mixed, further improving the stirring effect.

[0048] Example 2, refer to Figure 1-3In order to solve the existing problem of uneven heating in this embodiment, based on the same concept as the above-mentioned embodiment 1, the preparation device of high-purity bis(propyltriethoxysilane) disulfide further includes:

[0049] The heating assembly 300 also includes a connecting rod 301, which is located on the outside of the driving rod 202. An auxiliary plate 303 is arranged below the connecting rod 301. The auxiliary plate 303 is driven to rotate by the connecting rod 301, which assists in stirring while making the equipment run in an integrated manner, which is energy-saving and environmentally friendly. A heating rod 304 is arranged on the inner side of the auxiliary plate 303, and a heating layer 305 is arranged below the heating rod 304. The central heating rod 304 assists in heating to ensure uniform heating.

[0050] The connecting rod 301 and the driving rod 202 are installed in an integrated manner. The connecting rod 301 and the first rotating rod 302 are connected by hot melt connection. The first rotating rod 302 is evenly and equidistantly distributed below the connecting rod 301. The first rotating rod 302 is driven to rotate by the connecting rod 301, so that the equipment operates in an integrated manner and reduces energy consumption.

[0051] The first rotating rod 302 and the auxiliary plate 303 rotate in an integrated manner, and heating rods 304 are evenly and equidistantly distributed on the inner side of the auxiliary plate 303. The heating rods 304 are installed in an integrated manner with the device body 101. The first rotating rod 302 and the auxiliary plate 303 cooperate to assist in stirring the edge area, and at the same time, the heating rods 304 assist in heating to ensure uniform heating.

[0052] The specific working principle is: as mentioned above, during the rotation of the driving rod 202, the first rotating rod 302 is driven to rotate through the connecting rod 301, so that the first rotating rod 302 drives the auxiliary plate 303 to rotate, so that the auxiliary plate 303 also starts to rotate, and the stirring block 203 is pushed to the edge of the raw materials to assist in stirring. At the same time, the heating rod 304 performs auxiliary heating to ensure uniform heating. It should be noted that the heating rod 304 and the heating layer 305 cannot make the temperature inside the device body 101 exceed 85°C.

[0053] Example 3, refer to Figure 4-5 In this embodiment, in order to solve the problem that the rotation speed of the existing auxiliary plate 303 is too slow and cannot be adapted to the stirring block 203, based on the same concept as the above-mentioned embodiment 1, the preparation device of high-purity bis(propyltriethoxysilane) disulfide also includes:

[0054] The meshing assembly 400 also includes a fixed rod 401, which is located around the driving rod 202. The outer side of the fixed rod 401 is connected to a driving gear 404, which is connected to the driving gear 404 through the fixed rod 401 to prevent it from affecting the unloading during use. The outer side of the driving gear 404 is connected to a driven gear 405, and the lower part of the driven gear 405 is connected to a second rotating rod 402. The second rotating rod 402 is driven to rotate by the cooperation of the driving gear 404 and the driven gear 405, thereby increasing the rotation speed of the second rotating rod 402. The lower part of the second rotating rod 402 is connected to a limiting block 403.

[0055] The fixed rod 401 and the driving rod 202 rotate in an integrated manner, the fixed rod 401 and the driving gear 404 are connected by hot melt connection, and the driving gear 404 and the driven gear 405 are connected by meshing connection. The fixed rod 401 cooperates with the driving rod 202 to drive the driving gear 404 to rotate without affecting the addition of raw materials.

[0056] The driven gear 405 rotates with the second rotating rod 402 in an integrated manner, and auxiliary plates 303 are evenly and equidistantly distributed on the outer side of the second rotating rod 402. The second rotating rod 402 and the limit block 403 are connected in a rotating manner. The second rotating rod 402 is driven to rotate by the driven gear 405, so that the auxiliary plates 303 rotate quickly, thereby improving the stirring effect.

[0057] The specific working principle is: as mentioned above, when the driving rod 202 rotates, it drives the fixed rod 401 to rotate, so that the fixed rod 401 drives the driving gear 404 to rotate, so that the driving gear 404 and the driven gear 405 are meshed, so that the driven gear 405 also starts to rotate, and the driven gear 405 itself is smaller than the driving gear 404, so that the driven gear 405 rotates faster, and at the same time drives the second rotating rod 402 and the auxiliary plate 303 to rotate, to assist in stirring and improve the stirring effect.

[0058] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
