[0028] The following is combined with Figures 1 - 3A drying mechanism for sealing the source core of a seed source of the present utility model is described, including an installation base 10, a drying platform 20, a drying bracket 30, and a driving component 40; the drying platform 20 is fixedly arranged on the installation base 10, and a plurality of drying stations 21 for installing reaction vessels 70 are arranged at intervals along the length direction of the drying platform 20; the drying bracket 30 is fixedly arranged on the installation base 10, and a support plate body 31 is arranged at the top of the drying bracket 30, and the support plate body 31 is located above the drying platform 20; the driving component 40 is arranged on the support plate body 31, a drying head is arranged at the driving end of the driving component 40, the drying head is connected to a gas supply device through a gas supply pipeline, the gas supply device is used to input drying gas into the drying head, and the driving component 40 is used to drive the drying head to extend into the reaction vessel 70 on the drying station 21 for drying operation. The silver wire reacts with three reaction reagents and then is washed to obtain the source core. At this time, the source core is in a wet state. In this example, the drying head sprays gas into the reaction vessel 70 to achieve drying, which improves the drying efficiency and avoids adhesion between the source cores.
[0029] It can be understood that the reaction vessel 70 can be placed at the drying station 21. After placement, the reaction vessel 70 is located below the drying head. The drying head moves downward under the drive of the driving component 40, so that it can extend into the reaction vessel 70, and then dry gas is introduced. Under the action of the drying gas, the source core is dried. After drying is completed, the drying head is lifted by the driving component 40, so that the reaction vessel 70 can be transferred to other processes for further operation. The whole process is automatically completed by the driving component 40, which improves the degree of automation. And there are multiple drying stations 21 on the support plate body 31. Through the automatic drying method, high-volume and high-efficiency preparation can be achieved. When drying, the source cores can move relative to each other by introducing drying gas, which prevents mutual adhesion and prevents the source cores from adhering to the container wall, and speeds up the drying speed of the source cores and improves the drying efficiency.
[0030] Specifically, the reaction vessel 70 includes a vessel body and a sealing cover arranged at the position of the vessel mouth. A pipeline feed port is arranged on the sealing cover, and a reaction container is arranged inside the vessel body. The reaction container is used to load silver wire and reaction reagents, and the drying head can extend into the reaction container through this pipeline feed port. By extending into the reaction container, efficient drying can be achieved, and the loss of the source core during the drying process is avoided.
[0031] Specifically, the driving component 40 is an electric push rod, and the drying head is connected to the piston rod of the electric push rod. The electric push rod can push the piston rod to move, so that the drying head can extend into the reaction container in the reaction vessel 70 under the action of the electric push rod, and drying gas is input through the gas supply pipeline, thereby realizing the drying of the source core in the reaction container.
[0032] According to an embodiment provided by the present utility model, the drying head includes a first connection part 411, a connection head 412, and a jet pipe 413. The first connection part 411 is connected to the output end of the driving component 40. The connection head 412 is arranged between the first connection part 411 and the jet pipe 413. The jet pipe 413 is communicated with the connection head 412. The connection head 412 is connected to the gas supply pipeline. The jet pipe 413 is configured to be able to extend into the reaction tank 70. When drying with dry gas, the source core can be prevented from sticking and adhering to the container wall. In this embodiment, the drying head is a split connection structure, which is conducive to installation and reduces the preparation difficulty.
[0033] It can be understood that the jet pipe 413 is used to spray dry gas into the reaction tank 70 to realize the drying of the source core in the reaction container. The length of the jet pipe 413 will affect the drying effect at the bottom end of the jet pipe 413. In this embodiment, the jet pipe 413 is installed with the connection head 412, which is convenient for quick replacement when the sizes of different reaction tanks 70 are different, and can quickly realize the matching with the reaction tank 70.
[0034] Specifically, the jet pipe 413 has a jet end, and a plurality of jet holes 4131 are opened on the jet end. The arrangement of the jet holes 4131 makes the ejected gas more uniform, and can realize the rapid drying of the source core.
[0035] In a specific implementation manner, the jet end is a round head structure, and the jet holes 4131 are uniformly opened on the jet end, so that the dry gas is ejected from the jet holes 4131, thereby realizing the drying of the source core.
[0036] According to the specific embodiment provided by the present utility model, the connection head 412 is provided with a connection port 4121, and the connection port 4121 is connected to the gas supply pipeline. During the gas input process, it is necessary to connect the gas supply pipeline with the connection head 412. In this embodiment, the connection head 412 is provided with the connection port 4121, and the connection with the gas supply pipeline can be quickly realized through the connection port 4121, which is convenient for installation and reduces the installation difficulty.
[0037] According to an embodiment provided by the present utility model, the drying station 21 includes a limit base, and the limit base has a limit sunk platform 211 for cooperating with the reaction tank 70 for limiting. The reaction tank 70 only needs to be stably installed at the drying station 21. In this embodiment, the way of the limit base can prevent the reaction tank 70 from shaking, so as to realize the stable placement of the reaction tank 70.
[0038] Specifically, the gas supply device includes an air compressor (not shown) and a gas storage tank (not shown). The air compressor and the gas storage tank can be arranged outside the installation base 10. The gas storage tank is connected to the air compressor, and the gas supply pipeline is connected to the gas storage tank, so that the dry gas is input into the drying head through the gas supply pipeline.
[0039] In a specific implementation, the central axis of the limiting sink 211 is in the same straight line as the central axis of the drying head, that is, the drying head can be extended into the reaction tank 70 by moving up and down, simplifying the movement process of drying.
[0040] According to the embodiment provided by the utility model, a plurality of driving components 40 are provided on the support plate 31, each driving component 40 is provided in one-to-one correspondence with the drying station 21, and the driving component 40 is located directly above the drying station 21. During the drying process, a certain waiting time is required. In this embodiment, each drying station 21 is independently provided with a driving component 40, so that each drying station 21 has an independent drying system, thereby achieving independent drying, improving drying efficiency, and facilitating batch preparation.
[0041] It can be understood that different drying times can correspond to different drying states during the drying process. In this embodiment, independent drying is achieved through the blocked driving component 40 and the drying head corresponding to each drying station 21, which can shorten the drying waiting time and improve the drying efficiency during mass production.
[0042] For example, in the batch preparation process, the preparation completion time of each source core is different. The source core prepared first can choose one of the drying stations 21 for independent drying, and the other source cores prepared continuously can also choose different drying stations 21 for drying, which can realize assembly line operation and improve preparation efficiency.
[0043] According to an embodiment provided by the utility model, a connecting hole 311 is provided on the support plate body 31, and an air supply pipeline is provided in the connecting hole 311. The air supply pipeline is used to connect the air supply device and the drying head. In this embodiment, by providing the connecting hole 311 on the support plate, the air supply pipeline is passed through from above and connected to the drying head located below the support plate body 31, so as to avoid the air supply pipeline affecting the reaction tank 70 on the drying station 21.
[0044] In the specific configuration, the air supply pipeline includes a spiral air pipe 50, and a portion of the spiral air pipe 50 is located in the connecting hole 311. When drying, the driving component 40 needs to drive the piston head to move, and the piston head moves while driving the air supply pipeline to move. The spiral air pipe 50 is used to keep the pipeline unobstructed when moving up and down, and should not affect the operation of other components.
[0045] In the specific implementation manner, a fixing bracket 60 is provided on one side of each communication hole 311. A fixing hole is formed in the fixing bracket 60. A part of the pipe body of the air supply pipe passes through the fixing hole and can be fixedly connected in the fixing hole. This makes a section of the air supply pipe extending downward from the support plate body 31 a spiral air pipe 50, and the spiral air pipe 50 can always be in communication with the drying head during the up and down movement. The overall structural arrangement is simple and convenient for manufacturing.
[0046] According to an embodiment provided by the present utility model, the drying bracket 30 further includes two columns 32. The columns 32 are fixedly arranged on the installation base 10 and are located at both ends of the drying platform 20. Both ends of the support plate body 31 are fixedly connected to the columns 32. The two columns 32 provide support for the support plate body 31, making the drying bracket 30 more stable.
[0047] Through the description of the above embodiments, those skilled in the art can clearly understand that in each embodiment of the present utility model, the driving component 40 and the drying head are arranged above the drying station 21 in an up and down setting manner. During drying, the drying is realized by driving the drying head to extend into the reaction tank 70, providing an automated drying mechanism, which is convenient for automated layout and provides an effective and reliable solution for fully automated preparation and large-scale preparation. Further, by the way of the drying head jetting air, the source cores can move relative to each other, preventing adhesion to each other and accelerating the drying speed of the source cores, improving the drying efficiency.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and are not intended to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
