Abstract
Description
Technical Field
[0001] This invention belongs to the field of silver carbonate preparation technology, specifically relating to a counter-rotating device and a silver carbonate synthesis device. Background Technology
[0002] Silver carbonate is an inorganic compound that is a white powder when freshly precipitated. It turns yellow when heated or left for a long time, and its color is dark under light. After drying, it becomes grayish-yellow. There are several preparation methods for silver carbonate, including precipitation and silver oxide carbonation.
[0003] For the precipitation method, silver nitrate needs to be reacted with sodium carbonate. First, water and sodium carbonate are added to a container, the sodium carbonate is dissolved, and then silver nitrate solution is added and stirred. After that, the mixture is filtered, the precipitate is washed with a small amount of acetone, air-dried, and stored in a brown bottle. The whole operation must be carried out in a dark room or under an infrared lamp to avoid the decomposition of silver carbonate by light.
[0004] In existing technologies, the mixing of sodium carbonate solution and silver nitrate solution is generally carried out by rotating a unidirectional stirring paddle. This method makes it difficult to ensure that the two solutions are fully and evenly mixed. In the case of uneven mixing, not only will the yield of silver carbonate be reduced, but also a large amount of unreacted silver nitrate or sodium carbonate will remain in the solution after the reaction, which will bring difficulties to subsequent separation and purification.
[0005] Therefore, a counter-rotating device and a silver carbonate synthesis device are designed to solve the technical problem in the prior art where unidirectional stirring of the mixed solution fails to achieve sufficient mixing, thus affecting subsequent separation and purification.
[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0070] Research has found that in existing technologies, the mixing of sodium carbonate and silver nitrate solutions generally uses a unidirectional stirring paddle. This method makes it difficult to ensure that the two solutions are fully and evenly mixed. Incomplete mixing not only reduces the yield of silver carbonate but also leaves a large amount of unreacted silver nitrate or sodium carbonate in the solution after the reaction, which makes subsequent separation and purification difficult.
[0071] Based on the above research, this disclosure provides a counter-rotating device and a silver carbonate synthesis device. By providing a convection mechanism and setting at least two mixing paddles on the main shaft, the sodium carbonate solution and silver nitrate solution can be fully convectively mixed and homogeneous after the reaction, avoiding the presence of a large amount of unreacted silver nitrate or sodium carbonate in the solution after the reaction, which would make subsequent separation and purification difficult.
[0072] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0073] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0074] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0075] In some embodiments, such as Figure 1 and Figure 2 As shown, sodium carbonate and water are added together into the dissolving reactor 4, and the driver 41 is started. Its output end drives the dissolving stirring shaft 411 to rotate. The anchor stirring paddle 412 is used to fully dissolve the sodium carbonate. Then, the sodium carbonate solution is introduced into the synthesis reactor 1 through the feed pipe 42. Silver nitrate solution is added into the synthesis reactor 1, and the motor 11 is started to stir and mix the two solutions in the synthesis reactor 1.
[0076] In some embodiments, such as Figure 2 As shown, after the motor 11 starts, it drives the main shaft 20 to rotate. The main shaft 20 is provided with mixing paddles 21 on both the upper and lower sides of its outer wall. The lower mixing paddle 21 is fixed to the main shaft 20 to rotate in the same direction as the main shaft 20. The upper mixing paddle 21 is connected to the main shaft 20 through the reversing component 3 to achieve reversal. The two mixing paddles 21 are in reverse to generate convection in the mixed solution, so that the mixed solution is fully mixed and uniform.
[0077] In some embodiments, such as Figure 3 and Figure 4 As shown, during the forward rotation of the main shaft 20, it drives the forward-rotating internal gear ring 300 fixed to it to rotate. The forward-rotating gear 301 meshes with the forward-rotating internal gear ring 300, so the forward-rotating gear 301 rotates in the same direction as the main shaft 20, thereby driving the reverse gear 311 meshing with the forward-rotating gear 301 to rotate. The rotation direction of the reverse gear 311 is opposite to that of the forward-rotating gear 301. At the same time, since the reverse gear 311 meshes with the reverse internal gear ring 310, the rotation direction of the reverse internal gear ring 310 is opposite to that of the main shaft 20. The reverse internal gear ring 310 is fixed to the bearing sleeve 312. At this time, since the bearing sleeve 312 is connected to the outer wall bearing of the main shaft 20, the bearing sleeve 312 can drive the upper mixing paddle 21 fixed on its outer wall to reverse. The two mixing paddles 21 are reversed to generate convection in the mixed solution, so that the mixed solution is fully mixed and uniform. In order to further mix the two solutions evenly, the motor 11 can be periodically controlled to rotate forward and reverse, that is, the two mixing paddles 21 are used to form the mixed solution in the synthesis reactor 1 into opposing swirling flow or reverse coaxial swirling flow, thereby further mixing the mixed solution in the synthesis reactor 1 evenly.
[0078] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0079] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0080] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0081] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0082] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
