[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0016] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
[0017] like Figures 1-2 As shown, a fine chemical reaction vessel with automatic sampling function includes a reaction vessel body 1, a sampling tube 2 suitable for sampling from inside the reaction vessel body 1, an adjusting component 3 for adjusting the sampling height of the sampling tube 2, and a moving support component. The reaction vessel body 1 has support legs of a predetermined height and can be equipped with a mixing component (the specific structure of the mixing component is prior art and will not be described in detail in this application) to fully mix the water inside the reaction vessel. A pressure pump 14 is connected to the top wall of the reaction vessel, which can change the pressure inside the reaction vessel during sampling, so that the water inside can be discharged from the sampling tube 2 into the sampling container 5 of the moving support component. The moving support component includes a moving frame 4, with moving wheels mounted at the bottom of the moving frame 4. The moving frame 4 is set at a predetermined height, and the top surface is a support plate. The support plate has a placement slot adapted to the sampling container 5. Multiple placement slots are provided to place multiple sampling containers 5. Multiple sampling containers 5 can carry water samples at different heights, and then are transferred to the detection position for detection and identification by the moving frame 4.
[0018] Preferably, the side wall of the reactor is provided with a support plate 16, which is adapted to be supported on the bottom of the upper support plate of the movable frame 4. When the movable frame 4 moves, the upper support plate and the support plate 16 are slidably configured, which can make the movable frame 4 move stably and facilitate the movement of the corresponding sampling container 5 to the sampling port of the sampling tube 2.
[0019] In some preferred embodiments, the adjusting assembly 3 includes a fixing rod 6 disposed within the reactor, the fixing rod 6 extending along the height direction of the reactor, and both ends of the fixing rod 6 bent toward the inner sidewall of the reactor and fixed thereon; a lifting plate 7, one end of which slides along the fixing rod 6, and the other end of which is connected to a lifting rod 8, the lifting rod 8 extending along the height direction of the reactor and extending beyond the top wall of the reactor, the top end of the lifting rod 8 bending laterally and connected to a lifting drive 13, the lifting drive 13 being disposed on the outer sidewall of the reactor via a mounting plate 12, wherein:
[0020] The sampling tube 2 is multi-segmented, including a sampling segment 9, a corrugated pipe segment 10, and a discharge segment 11. The sampling segment 9 passes through the lifting plate 7 and the sampling end is located below the lifting plate 7. The two ends of the corrugated pipe are connected to the sampling segment 9 and the discharge segment 11, respectively. The corrugated pipe can deform appropriately when the sampling segment 9 moves up and down with the lifting plate 7. The discharge segment 11 extends out of the top wall of the reactor and bends to the side of the reactor. The discharge end of the discharge segment 11 extends along the height direction of the reactor to the sampling container 5. After the booster pump is started, the internal water enters from the sampling end and is discharged from the discharge end to the sampling container 5.
[0021] When it is necessary to adjust the sampling height inside the reactor, the lifting drive 13 can be activated. The lifting drive 13 can be a cylinder or other telescopic drive. After activation, the telescopic end extends and retracts, and the lifting rod 8 rises or falls with the telescopic end. The lifting plate 7 rises or falls accordingly. At this time, the corrugated pipe section 10 of the sampling tube 2 extends or retracts, and the sampling end of the sampling section 9 changes the sampling height with the lifting plate 7.
[0022] It should be noted that the sampling tube 2's discharge section 11 can penetrate the mounting plate 12, and the mounting plate 12 limits the discharge section 11. In addition, the sampling tube 2 is equipped with a solenoid valve 15, which can be opened during sampling.
[0023] It should also be noted that the lifting rod 8 is slidably connected to the top of the reactor, and a corresponding sealing sleeve is provided at the connection point. A sealing sleeve is also provided at the connection point between the sampling tube 2 and the top wall of the reactor.
[0024] In some preferred embodiments, the upper and lower parts of the reactor inner chamber are connected to corresponding pipes, and the two pipes can be connected to the inlet and outlet of the pump body (e.g., a booster pump). After the pump body is started, the water in the upper and lower parts of the reactor is circulated to assist in the full mixing and reaction of the water. The pipe connected to the upper part of the reactor inner chamber can be connected to a water distributor to further promote the uniform mixing of the water.
[0025] The specific usage is as follows: Install the entire device in a suitable working position; when sampling is required, the operator pushes the moving frame 4 to the support plate 16 of the reactor and aligns the sampling container 5 with the discharge end of the sampling form; start the lifting drive 13, adjust the height of the lifting plate 7, and then adjust the sampling port to a suitable height. The height of the sampling end can be determined by judging the extension stroke of the lifting drive 13 from the outside or by setting part of the reactor side wall to transparent and marking the height; then, start the booster pump and open the solenoid valve 15 of the sampling tube 2, so that after the sampling tube 2 is opened, the water inside the reactor is squeezed out from the sampling port and enters the sampling container 5 for collection; turn off the booster pump and the solenoid valve 15, continue to push the moving frame 4 so that the second sampling container 5 is aligned below the discharge end, and then adjust the sampling height to perform sampling at different height positions. After sampling is completed, the operator can directly push the mobile frame 4 to transfer multiple sampling containers 5 to the testing and inspection work position. The above operation can facilitate sampling and carrying at different heights inside the reactor, and after sampling is completed, multiple sampling containers 5 can be directly transferred, improving work efficiency.
[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents. In summary, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention. Each component of this application can be driven by a corresponding external motor; this is prior art and will not be elaborated upon here.
