[0024] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] The various specific technical features in the various embodiments described in the specific implementation methods can be combined in various ways without contradiction. For example, different implementation methods can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the present invention will not be described separately.

[0026] It should also be noted here that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the solutions of the present invention are shown in the drawings, while other details that are not closely related to the present invention are omitted.

[0027] In addition, it should be noted that the terms "include", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the following description, the terms "first\second\..." involved are merely used to distinguish different objects and do not indicate that there is any similarity or connection between the objects. It should be understood that the directions described by the directional nouns such as "above", "below", "inside" and "outside" are all directions in normal use.

[0028] In the following specific embodiments, a post-processing device integrating washing, separation, and drying is used to post-process silver after a reduction reaction, so that the mixture of the silver after the reduction reaction and the reducing agent is separated and dried to form powdered solid silver, that is, silver powder. In addition, the post-processing device washes, separates, and dries the reduced silver at the same location, thereby eliminating the need to transfer the silver between multiple workstations and reducing the transfer loss of silver powder. The structure and function of the post-processing device integrating washing, separation, and drying are exemplified below in conjunction with various embodiments.

[0029] In some embodiments, as Figure 1 As shown, the post-processing device 10 with integrated washing, separation and drying includes: a shell 100, a heating component 200 and a filter element 300. The shell 100 has a accommodating space 110 inside, which is used to accommodate the reduced silver. The shell 100 also has a detergent inlet 120, a modifier inlet 130, a drain port 140, an air inlet 150 and an exhaust port 160. At the same time, the heating component 200 is used to heat the accommodating space 110. The filter element 300 is located between the accommodating space 110 and the drain port 140. The washing, separation and drying of silver are all carried out in the accommodating space 110. The washing, separation and drying processes are described in detail below.

[0030] After the reduced silver enters the storage space, the post-processing device starts the reducing agent separation process. During this process, inert gas enters the storage space through the air inlet 150, thereby separating the reducing agent from the silver through air pressure. The squeezed reducing agent passes through the filter element 200 and is discharged from the storage space through the drain port 140, thereby achieving separation of the reducing agent and the silver. After the separation of the reducing agent is completed, the washing process begins. During this process, the detergent enters the storage space 110 through the detergent inlet 120 and mixes with the silver in the storage space 110 to wash the silver. After the washing is completed, the inert gas is again introduced into the storage space 110 through the air inlet 150, so that the detergent after washing the silver passes through the filter element 200 and is discharged from the storage space through the drain port 140. In addition to being used to further clean the silver, the detergent can also reduce the hydroxyl content on the silver surface and reduce the agglomeration phenomenon caused by capillary action in the subsequent drying process. After the washing is completed, the modification process begins. During this process, the modifier enters the storage space through the modifier inlet 130. The modifier is mixed with silver in the storage space 110, and the modifier can be coated on the surface of the silver, thereby changing the physical and chemical properties of the silver. For example, the physical and chemical properties include inhibiting agglomeration, improving dispersibility, enhancing chemical stability, optimizing application performance adaptability, enhancing electrical conductivity and process compatibility. After the modification process is completed, the modifier washing process begins. During this process, the detergent enters the storage space through the detergent inlet 120 to separate the excess modifier from the silver, and the detergent after washing can pass through the filter element 300 and be discharged from the drain port. After the modifier washing is completed, the drying process begins. During this process, the heating component heats the storage space and the exhaust port continuously extracts the gas in the storage space to maintain a negative pressure state in the storage space. The negative pressure state can not only quickly evaporate the remaining liquid (the remaining liquid may be residual detergent) into gas, but also quickly discharge the evaporated residual liquid into gas from the storage space 110 through the suction effect, so that the silver forms a powdery solid structure, that is, silver powder.

[0031] It should be noted that the heating component 200 can heat the accommodating space 110 in any manner. Exemplarily, the heating component 200 is a heating wire directly disposed in the accommodating space 110 . Exemplarily, the heating component 200 is a heating water jacket located outside the accommodating space.

[0032] Among them, the air inlet 150 has an air inlet valve, and the exhaust port 160 has an exhaust valve. When the air inlet valve is open, the exhaust valve is closed. That is, in the process of pressurizing the containing space 110 with inert gas to separate the reducing agent, detergent or modifier from silver, the exhaust valve is closed so that the air pressure in the containing space 110 can rise rapidly, so that the reducing agent, detergent or modifier can be more thoroughly separated from the silver; when the exhaust valve is open, the air inlet valve is closed. It can be understood that during the drying process, when the gas in the containing space 110 is extracted through the exhaust port 160, neither external air nor inert gas will be introduced into the containing space 110. It should be noted that those skilled in the art generally believe that in order to make the exhaust process more thorough, new gas needs to be introduced into the containing space while the gas is extracted, so as to make the air pressure between the containing space and the exhaust device more stable. A stable pressure difference is formed during the drying process so that the exhaust process can continue. However, those skilled in the art did not realize that the external air or inert gas introduced may inevitably contain moisture, which causes the moisture to repeatedly combine with the silver powder during the drying process, resulting in some silver powder still being in a clustered and compacted state after drying. It is based on the awareness of this problem that the applicant has in mind that the liquid is converted into gas during the drying process, which will cause the air pressure in the containing space to rise to a certain extent, and the containing space in a negative pressure state can also accelerate the rate of evaporation of the liquid into gas. Therefore, if a sufficiently powerful exhaust device is provided, not only can the exhaust process be continued for a sufficiently long time, but the evaporation rate of moisture can also be accelerated without introducing external moisture, thereby improving the thoroughness of the drying and reducing the degree of compaction of the silver powder after drying.

[0033] An embodiment of the present invention provides a post-processing device integrating washing, separation and drying, which is used to post-process silver to form silver powder. The post-processing device includes: a shell having a accommodating space, and the shell has a detergent inlet, a modifier inlet, a drain port, an air inlet and an exhaust port connected to the accommodating space; the post-processing device also includes a heating component for heating the accommodating space, and a filter element located between the accommodating space and the drain port, so that the separation process of the reducing agent and silver, the washing process, the modification process and the drying process can all be carried out in the same accommodating space. There is no need to transfer the silver during the post-processing process, thereby reducing the amount of silver loss during the post-processing process. Among them, the air inlet has an air inlet valve, and the exhaust port has an exhaust valve. When the air inlet is open, the exhaust port is closed, so that when the inert gas enters the containing space from the air inlet, the air pressure in the containing space is rapidly increased, so that the reducing agent, detergent or modifier and silver can be more thoroughly separated; when the exhaust valve is open, the air inlet valve is closed, so that during the drying process, no external air or inert gas that may contain moisture is introduced, and the containing space is kept in a negative pressure state, thereby accelerating the evaporation rate of moisture in the containing space, thereby improving the drying effect on silver and reducing the degree of compaction of the silver powder after drying.

[0034] In some embodiments, as Figure 2 As shown, the shell 100 also has a heating interlayer 170, which is coated on the outside of the accommodating space 110. The heating interlayer 170 can exchange heat with the accommodating space 110, and the heating interlayer 170 is isolated from the accommodating space 110, that is, only heat exchange can be carried out between the two spaces, but the gases or liquids in the two spaces cannot be exchanged with each other; wherein, the heating component 200 is used to pass the heating medium into the heating interlayer and discharge the heating medium after heat exchange out of the heating interlayer 170. It can be understood that by arranging the heating part in the heating interlayer 170, the detergent and modifier in the accommodating space 110 will not affect the heating component 200, and the heating medium flows in the heating interlayer 170 to heat the accommodating space 110, so that the accommodating space 110 can be heated more evenly and the temperature control in the accommodating space 110 is more convenient, thereby further improving the drying effect of the silver powder.

[0035] Optional, such as Figure 2 As shown, the housing 100 further includes a heat insulating structure 171 , which is coated on the outside of the heating interlayer 170 , thereby reducing heat loss of the heating medium in the heating interlayer 170 and further improving the drying effect of the silver powder.

[0036] In some embodiments, as Figure 2As shown, the post-processing device also includes a frame 400, which is rotatably connected to the shell 100. The shell 100 can rotate relative to the frame 400. The rotation of the shell 100 can make the detergent and the modifier more fully mixed with the silver, thereby improving the washing effect and the modifying effect; wherein, the shell 100 includes a rotating part 181 and a fixed part 182, and the accommodating space 110 is located in the rotating part 181 so that the silver in the accommodating space can be fully mixed with the detergent or the modifier, and the detergent inlet 120, the modifier inlet 130, the air inlet 150 and the exhaust port 160 are all located in the rotating part. The rotating part, so that when the external detergent supply device, the external modifier supply device, the external inert gas supply device and the external exhaust device are connected to the various interfaces through pipelines, these pipelines do not need to rotate with the rotating part, so that the connection between the pipelines and the various interfaces is more reliable. At the same time, the rotating part 181 and the fixed part 182 are rotationally sealed and connected, that is, the connection position of the rotating part 181 and the fixed part 182 is sealed by a sealing structure or by a tight fit, so that the two parts can rotate relative to each other while preventing gas or liquid from leaking from the connection position.

[0037] In some embodiments, as Figure 2 As shown, the fixed part 182 includes a functional part 183, and the detergent inlet 120, the modifier inlet 130, the air inlet 150 and the exhaust port 160 are all arranged in the functional part 183. Specifically, the functional part 183 has a connecting channel connected to the accommodating space, and the detergent inlet 120, the modifier inlet 130, the air inlet 150 and the exhaust port 160 are all connected to the connecting channel, that is, each interface is arranged in the same part of the fixed part 182 and shares a connecting channel to be connected with the accommodating space 110 through the connecting channel, which not only makes the setting position of each interface more compact and reduces the volume of the fixed part 182, but also the installation position of the external pipeline is concentrated in this area, thereby facilitating the installation and disassembly of the external pipeline.

[0038] In some embodiments, as Figure 2As shown, the rotating part 181 has a heating interlayer 170, and the fixed part 182 also includes a heat supply part 184, and the heat supply part 184 has a heating medium inlet 185 and a heating medium outlet 186, wherein the heating component 200 is connected to the heating medium inlet 185 and the heating medium outlet 186, for allowing the heating medium to flow into the heating interlayer 170 from the heating medium inlet 185 and for allowing the heating medium to be discharged from the heating interlayer 170 from the heating medium outlet 186 after the heat exchange is completed. It can be understood that by setting the connecting port of the heating medium at the same position, the connection and disassembly of the heating component 200 are facilitated, and by rotating the heating interlayer 170, the heating medium can also rotate in the heating interlayer 170 so that the heating medium can heat the accommodating space 110 more evenly, further improving the drying effect.

[0039] Optional, such as Figure 2 As shown, in a direction parallel to the rotation axis of the rotating part 181, the functional part 183 and the heating part 184 are respectively located at the two ends of the rotating part 181, so that the interface for communicating with the accommodating space 110 and the interface for communicating with the heating interlayer 170 are located at the two ends of the rotating part 181, so that the installation position of the pipeline for communicating with the accommodating space 110 and the pipeline for communicating with the heating interlayer 170 maintain a certain distance, which not only reduces the risk of assembly interference between the two pipelines, but also reduces the influence of the heating medium on the temperature of the liquid or gas in other pipelines. Optionally, as Figure 2 As shown, the post-processing device further includes a driving assembly 500, which is used to connect with the housing 100 and drive the housing 100 to rotate. For example, Figure 3 As shown, the driving assembly 500 includes a driving motor 510, a transmission belt 520 and a transmission shaft 530. The driving motor 510 is fixedly connected to the frame 400. The driving motor 510 is connected to the transmission shaft 530 through the transmission belt 520. The transmission shaft 530 drives the housing 100 to rotate.

[0040] In some embodiments, as Figure 2As shown, the detergent inlet 120 includes a first detergent inlet 121 and a second detergent inlet 122 that are spaced apart. The first detergent inlet 121 is used to introduce pure water into the accommodating space 110, and the second detergent inlet 122 is used to introduce an organic solvent into the accommodating space. Pure water is used to remove residual reducing agents, dispersants, and reaction by-products to prevent impurities from affecting performance during subsequent drying or sintering. The organic solvent is used to perform solvent replacement with a liquid that easily causes silver powder agglomeration. By replacing water with an organic solvent, the hydroxyl content on the surface of the silver powder is reduced, and the risk of hard agglomeration caused by capillary action during the drying process is reduced. The organic solvent can be, for example, anhydrous ethanol or acetone. Optionally, in the process of replacing water with an organic solvent or cleaning the modifier with an organic solvent, multiple washing and separation can be performed with an organic solvent to further improve the washing effect.

[0041] In some embodiments, as Figure 1 As shown, the post-processing device also includes a medicine dispensing device 600, which is located in the accommodating space 110 and is connected to the modifier inlet 130, wherein a plurality of medicine dispensing holes 610 are arranged at intervals, and each medicine dispensing hole 610 is connected to the modifier inlet 130. The modifier can be evenly sprayed into the accommodating space 110 through the plurality of medicine dispensing holes 610, so that the modifier can be more evenly contacted with the silver in the accommodating space 110, thereby improving the modification effect.

[0042] Optional, such as Figure 1 As shown, the inner surface of the receiving space 110 forms a guide surface, which is used to concentrate the silver at the middle position of the bottom of the receiving space 110, so that the silver can be more fully mixed with the detergent or modifier. In addition, the drain port 140 can be located at the lowest position of the receiving space 110. When the drain port 140 is rotated to the bottom of the receiving space 110, the drain port 140 can be located at the lowest position of the receiving space 110, so that the liquid in the receiving space 110 can be fully discharged under the action of the guide surface. Figure 1 As shown, the filter element 300 is located outside the accommodating space 110 and the filter element 300 is detachably connected to the housing 100 , so that the filter element 300 can be quickly replaced when the filter element 300 is blocked.

[0043] The second aspect of the embodiments of the present invention further provides a post-processing system that integrates washing, separation, and drying. The post-processing system is used to automatically post-process the reduced silver so that the silver reduced by silver nitrate is processed into silver powder. The structure and function of the post-processing system are exemplified below in conjunction with various embodiments.

[0044] In some embodiments, combined Figure 1 and Figure 4The post-processing system of washing, separation and drying integration includes the following Figures 1 to 3 The post-processing device 10 of the washing, separation and drying integration shown in any one of the drawings, as well as the detergent supply component 20, the modifier supply component 30, the air supply component 40 and the exhaust component 50, the detergent supply component 20 is connected to the detergent inlet 120, for introducing detergent into the accommodating space 110; the modifier supply component 30 is connected to the modifier inlet 130, for introducing the modifier into the accommodating space; the air supply component 40 is connected to the air inlet 150, for introducing an inert gas into the accommodating space, the inert gas is, for example, For example, nitrogen can be used; the exhaust assembly 50 is connected to the exhaust port 160 to maintain a negative pressure in the storage space 110; it can be understood that by providing the detergent supply assembly 20, the modifier supply assembly 30, the air supply assembly 40, and the exhaust assembly 50 and connecting them to each interface through pipelines, the post-processing system can automatically wash, separate, modify, and dry the silver, and these processes are all carried out in the same storage space 110, thereby eliminating the need to transfer the silver between multiple stations and reducing silver loss. Optionally, the pipelines for supplying the detergent and modifier are each equipped with a metering pump to achieve quantitative supply of the detergent and modifier in the storage space.

[0045] Among them, Figure 5 As shown, the shell 100 also has a heating interlayer 170, which is coated on the outside of the accommodating space 110 and can exchange heat with the accommodating space 110. The shell 100 has a heating medium inlet 185 and a heating medium outlet 186 connected to the heating interlayer 170. The heating component 200 includes a first pipeline 210 connected to the heating medium inlet 185 and a second pipeline 220 connected to the heating medium outlet 186. The post-processing system also includes a heat source device 60. The first pipeline 210 and the second pipeline 220 are used to form a rotating pipeline to allow the heating medium to circulate between the heat source device 60 and the heating interlayer 170. By controlling the heating temperature of the heat source device 60 and the flow rate of the heating medium, the temperature in the accommodating space 110 can be precisely controlled.

[0046] In some embodiments, as Figure 4 As shown, the detergent supply assembly 20 includes a pure water supply device 21 and an organic solvent supply device 22, wherein the detergent inlet 120 includes a first detergent inlet 121 and a second detergent inlet 122 arranged at intervals, the pure water supply device 21 is connected to the first detergent inlet 121 for introducing pure water into the accommodating space 110, and the organic solvent supply device 22 is connected to the second detergent inlet 122 for introducing organic solvent into the accommodating space 110, so that different functions of washing can be performed by using different types of detergents.

[0047] In some embodiments, as Figure 4As shown, the post-processing system further includes: a raw material supply device 70 and a waste liquid tank 80. The raw material supply device 70 is used to store and supply silver after the reduction reaction is completed. The waste liquid tank 80 has a waste liquid storage space inside. The shell 10 has a raw material inlet 190. The raw material supply device 70 can pour the silver powder after the reduction reaction into the storage space 110 through the raw material inlet 190. Specifically, when it is necessary to load the silver after the reduction reaction, the raw material inlet 190 is rotated to be located directly above the shell 100 and the cover of the raw material inlet 190 is opened. At this time, the raw material supply device 70 pours the silver after the reduction reaction into the storage space 110 through the raw material inlet 190. In the subsequent process, the cover is closed to prevent the silver from leaking out of the storage space 110 through the raw material inlet 190. The waste liquid tank 80 is located directly below the shell 100. When draining is required, the drain port 140 is rotated to be located at the bottom of the shell 100, so that the liquid can flow into the waste liquid storage space, and the waste liquid is collected by the waste liquid tank 80 to prevent the waste liquid from affecting the environment.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention.
