Description

Technical Field

[0001] The invention relates to the technical field of production feeding, in particular to a closed automatic feeding device for block-shaped active metals. Background Art

[0002] In the chemical production process, adding bulk active metals to the reactor is a common operation. With the development of automation technology, the robot feeding method has been proposed. However, the robot method has the problem of high cost. The purchase cost, installation and commissioning cost, and later maintenance cost of the robot equipment itself are very high. For most users, it is difficult to accept this high-cost feeding method, which greatly limits the promotion of the robot feeding method in practical applications. At present, the feeding method of bulk active metals mainly relies on manual operation, that is, the operator directly feeds at the feeding port, but this manual feeding method has the following significant disadvantages: 1. Manual feeding has great safety risks when handling dangerous goods (such as active metal blocks). Due to the active chemical properties of active metals, they may react violently with the surrounding environment during the feeding process. Manual operation is difficult to accurately control various conditions, which can easily lead to dangerous accidents.

[0003] 2. There are often volatile, flammable and explosive organic solvents in the reactor. During the manual feeding process, since the feeding port is difficult to be completely sealed, the organic solvents are easy to evaporate from the feeding port, which will not only cause material loss, but also bring serious safety risks. The existing feeding method cannot achieve fully automatic inerting, closed and timed feeding operation, and it is difficult to accurately coordinate with the inerting operation, and it is impossible to ensure feeding in a safe inerting environment.

[0004] 3. Manual feeding not only requires the operator to have certain skills and experience, but also requires a lot of physical strength. After the feeding is completed, the feeding equipment needs to be manually cleaned, and the labor intensity of the workers is high. Summary of the invention

Under the action of the feeding control system, the first pneumatic air inlet valve 2002, the first pneumatic air outlet valve 2005, the second pneumatic air inlet valve 2102, and the second pneumatic air outlet valve 2105 are started, and the material barrel 07 and the buffer unit 19 are replaced with nitrogen to put them in a nitrogen environment. At the same time, the oxygen content analyzer 20 06 feedbacks the oxygen content in the barrel 07 and the buffer unit 19. When the oxygen content is lower than the set value, the nitrogen stops entering, and the servo motor 0906 drives the bullet clamp tube 1003 to rotate. When a bullet clamp tube 1003 rotates to above the barrel drop opening 0905, the pull tongue block groove 1004A of the corresponding draw plate 1004 just catches the pull tongue block 0903A of the draw plate pull tongue block 0903, and the guide rod cylinder 0902 moves to pull the draw plate 1004 out of the draw plate limit seat 1002, exposing the tube drop opening 1002A, and the buffer area feed valve 1901 is opened, and the sodium rod in the bullet clamp tube 1003 passes through the tube drop opening 1002A and the barrel drop opening 0905.

The buffer area feed valve 1901 is closed, and the buffer area discharge valve 1903 is opened. The sodium rod is put into the reactor 01, and the buffer area discharge valve 1903 is closed. The buffer unit inert gas replacement system 21 is used to replace the nitrogen in the buffer unit 19 again. When it is necessary to put sodium rods into the reactor 01 again, the servo motor 0906 drives the bullet clamp tube 1003 to rotate so that the other bullet clamp tube 1003 is located above the barrel drop port 0905, and the feeding is completed as described above.
