Description

Technical Field

[0001] This invention relates to the field of production material feeding technology, specifically to a closed automatic feeding device for blocky reactive metals. Background Technology

[0002] In chemical production processes, adding bulk reactive metals to reaction vessels is a common operation. With the development of automation technology, robotic feeding methods have been proposed. However, robotic methods suffer from excessively high costs. The purchase cost of the robotic equipment itself, the installation and commissioning cost, and the subsequent maintenance cost are all very high. For most users, this high cost of feeding methods is difficult to accept, which greatly limits the promotion of robotic feeding methods in practical applications. Currently, the feeding of bulk reactive metals mainly relies on manual operation, that is, operators directly add the material at the feeding port. However, this manual feeding method has the following significant drawbacks:

[0003] 1. Manual feeding poses a significant safety hazard when handling hazardous materials (such as bulk reactive metals). Due to the reactive nature of these metals, they may react violently with the surrounding environment during the feeding process. Manual operation makes it difficult to precisely control various conditions, which can easily lead to dangerous accidents.

[0004] 2. Reactors often contain volatile, flammable, and explosive organic solvents. During manual feeding, it is difficult to completely seal the feeding port, allowing the organic solvents to easily evaporate. This not only causes material loss but also poses serious safety risks. Existing feeding methods cannot achieve fully automated, inerting-sealed, and timed feeding operations, making it difficult to precisely coordinate with the inerting process and ensuring feeding is carried out in a safe inerting environment.

[0005] 3. Manual feeding not only requires operators to have certain skills and experience, but also requires a lot of physical strength. After feeding is completed, the feeding equipment needs to be cleaned manually, resulting in high labor intensity for workers. Summary of the Invention

Detailed Implementation

[0035] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0036] Please see Figures 1-14 One embodiment provided by the present invention:

[0037] An automatic closed feeding device for blocky reactive metals includes a reaction vessel 01, a platform 02, and a feeding device 05. The feeding device 05 includes a feeding device body 06, a buffer unit 19, a material tank inert gas replacement system 20, a buffer unit inert gas replacement system 21, a support column 18, and a feeding control system. The feeding device body 06 includes a material tank 07, a feeding rotation mechanism 08, a lid opening mechanism 12, a lid sealing unit, a lid pressing mechanism, and a cleaning mechanism 17. One end of the buffer unit 19 is fixedly connected to the bottom of the material tank 07. One end is fixedly connected to the feed inlet of the reactor 01. The buffer unit 19 is used to isolate the material tank 07 from the reactor 01 to prevent the material tank 07 from being directly connected to the reactor 01 during feeding, which would cause other gases to enter the reactor 01. One end of the support column 18 is fixedly connected to the bottom of the material tank 07, and the other end is fixedly connected to the floor to support the material tank 07. The feeding rotation mechanism 08 is set in the material tank 07 to feed the sodium rod into the buffer unit 19. One end of the lid opening mechanism 12 is fixedly connected to the bottom plate 0701 of the material tank 07. The other end is fixedly connected to the lid 0703 of the material hopper 07, used to open or close the lid 0703. The lid sealing unit is set inside the lid 0703 for sealing the lid 0703 with the body 0702 of the material hopper 07. The lid pressing mechanism is set on the material hopper 07 for pressing the lid 0703 onto the body 0702 when the lid 0703 is closed. The cleaning mechanism 17 is fixedly set inside the lid 0703 for cleaning the feeding channel after feeding is completed. The material hopper inert gas replacement system 20 is fixedly set on the material hopper 07. It is connected to the material bucket 07 to ensure the inert environment inside the material bucket 07. The inert gas replacement system 21 of the buffer unit is fixedly installed on the buffer unit 19 and connected to the buffer unit 19 to ensure the inert environment inside the buffer unit 19. The feeding control system is electrically connected to the feeding rotation mechanism 08, the lid opening mechanism 12, the lid pressing mechanism, the lid sealing unit, the buffer unit 19, the material bucket inert gas replacement system 20, and the buffer unit inert gas replacement system 21 to automatically control the feeding process of reactive metals.

The rotating platform component 09 includes a cylinder mounting shaft seat 0901, a guide rod cylinder 0902, a material bucket discharge port 0905, and a hollow rotating platform 0907. The material bucket discharge port 0905 is fixedly installed on the bottom plate 0701 near the outer edge. The cylinder mounting shaft seat 0901 is fixedly installed in the middle of the bottom plate 0701. The guide rod cylinder 0902 is fixedly installed on the upper part of the cylinder mounting shaft seat 0901. The guide rod of the guide rod cylinder 0902 is fixedly connected to a pull plate tongue block 0903. The pull plate tongue block 0903 faces the material bucket discharge port 0905. A pull tongue block 0903A is fixedly installed at the bottom of the pull plate tongue block 0903. The lower part of 0901 is fixedly connected to an air pipe 0904. The inlet and outlet air pipes of the guide rod cylinder 0902 can pass through the cylinder mounting shaft seat 0901 and the air pipe 0904 to connect to an external air source system. The hollow rotating platform 0907 is fixedly set on the bottom plate 0701 of the barrel and coaxially houses the cylinder mounting shaft seat 0901. A servo motor 0906 is fixedly installed at the bottom of the hollow rotating platform 0907. The feeding turntable component 10 includes a feeding turntable 1001, which is located above the bottom plate 0701 of the barrel and is connected to the hollow rotating platform 0907 in a transmission manner and is sealed and rotatably connected to the cylinder mounting shaft seat 0901. Eight drawer plate limiting seats 1002 are evenly distributed and fixedly connected to the outer edge of the feeding turntable 1001. A bullet-shaped feeding tube 1003 is fixedly connected above 1002. The bullet-shaped feeding tube 1003 is used to hold sodium rods. When the servo motor 0906 drives the hollow rotating platform 0907 to rotate, it can drive the feeding turntable 1001 and the bullet-shaped feeding tube 1003 to rotate around the axis of the feeding turntable 1001. A draw plate limit seat 1002 is provided with a draw plate pad 1005 at one end near the center of the feeding turntable 1001. The draw plate pad 1005 is fixedly connected to the feeding turntable 1001. The draw plate limit seat 1002 has a feeding tube discharge hole 1002A in the axial direction. A draw plate slot 1002B is provided in the middle of the feeding tube discharge hole 1002A. A draw plate 1004 is provided in the draw plate slot 1002B. The bottom surface of the draw plate 1004 is flush with the surface of the draw plate pad 1005. The surfaces are flush, allowing the pull plate pad 1005 to support the pull plate 1004, facilitating the sliding of the pull plate 1004 on the pull plate pad 1005. The pull plate 1004 has a pull tongue block groove 1004A at one end near the center of the feeding turntable 1001. The pull tongue block groove 1004A matches the pull tongue block 0903A, so that the pull tongue block 0903A is stuck in the pull tongue block groove 1004A of the pull plate 1004 located above the material barrel discharge port 0905, so that the guide rod cylinder 0902 can drive the pull plate 1004 to move, closing or exposing the material barrel discharge port 0905, and controlling the feeding of sodium rods in the bullet clamp material tube 1003. Several small holes 1004B for cleaning liquid are opened in the middle of the pull plate 1004, so that the cleaning liquid can flow into the cleaning liquid channel 11 from here during cleaning.

[0039] The lid opening mechanism 12 includes a lid connecting block 1201, a lid opening cylinder 1202, a connecting block support 1203, and a U-shaped support tube 1205.

The bottom of the lid opening cylinder 1202 is hinged to the lid opening cylinder connector 1204. By controlling the action of the lid opening cylinder 1202, the function of opening or closing the barrel lid 0703 can be realized.

[0040] The barrel lid sealing unit includes an airbag sealing ring 15 and an inflation hose 16. An airbag groove is provided at the bottom edge of the barrel lid 0703. The airbag sealing ring 15 is installed in the airbag groove. One end of the inflation hose 16 is located above the barrel lid 0703 and connected to an external inflation device. The other end passes through the barrel lid 0703 and communicates with the airbag sealing ring 15. After the barrel lid pressing mechanism presses the barrel lid 0703 onto the barrel body 0702, the airbag sealing ring 15 is inflated to fill the airbag groove, thereby achieving the sealing function between the barrel lid 0703 and the barrel body 0702.

[0041] The lid clamping mechanism includes a manual clamping device 13 and a pneumatic clamping device 14. The manual clamping device 13 includes a matching latch 1301 and a buckle 1302.

A flow channel annular plate 1103 is fixedly installed between the outer wall 1101 and the inner wall 1102. The outer wall 1101 and inner wall 1102 of the flow channel intersect obliquely. A discharge port 1104 is provided at the lowest point where the flow channel ring plate 1103 intersects with the outer wall 1101. The purpose is to allow the cleaning liquid in the cleaning liquid flow channel 11 to collect here by gravity during cleaning, preventing the cleaning liquid from accumulating on the flow channel ring plate 1103. A notch 1105 is provided at the intersection of the inner wall 1102 of the flow channel and the discharge port 1104 to avoid interference between the material barrel discharge port 0905 and the inner wall 1102 of the flow channel. The cleaning liquid flow channel 11 is located between the bottom plate 0701 of the barrel and the feeding turntable 1001. The inner wall 1102 of the flow channel is fitted outside the hollow rotating platform 0907. The material barrel discharge port 0905 passes through the discharge port 1104. An inclined groove 0905A is provided in the material barrel discharge port 0905. The inclined groove 0905A is flush with the flow channel ring plate 1103.

[0043] During cleaning, the cleaning fluid is sprayed from the atomizing nozzle 1703 into the bullet clip tube 1003 through the cleaning fluid inlet 1704 and the U-shaped cleaning pipe 1701 to clean the bullet clip tube 1003. The cleaning fluid in the bullet clip tube 1003 flows into the cleaning fluid channel 11 through the cleaning fluid hole 1004B on the draw plate 1004, and collects at the lowest point where the channel ring plate 1103 and the outer wall 1101 of the channel meet, that is, at the material barrel drop port 0905. Then it flows into the material barrel drop port 0905 through the inclined groove 0905A and enters the buffer material tube 1902 to clean the buffer material tube 1902 before being discharged. After cleaning, it is air-dried.

[0044] The buffer unit 19 includes a buffer feed pipe 1902. A buffer zone feed valve 1901 and a buffer zone discharge valve 1903 are fixedly connected to the upper and lower ends of the buffer feed pipe 1902, respectively.

[0048] Working principle of this invention: Initially, all valves are closed. In use, sodium rods are placed sequentially into the bullet clamp tube 1003. The barrel lid 0703 is closed and pressed tightly using the pneumatic clamping device 14 and the manual clamping device 13. The airbag sealing ring 15 is inflated to seal the barrel lid 0703 against the barrel body 0702. The manual air inlet valve 2003 is opened. 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 activated, purging the material barrel 07 and the buffer unit 19 with nitrogen to create a nitrogen environment. Simultaneously, the oxygen content analyzer 20... 06 Feedback material barrel 07 and buffer unit 19 oxygen content. When the oxygen content is lower than the set value, nitrogen gas intake stops. Servo motor 0906 drives bullet clip tube 1003 to rotate. When a bullet clip tube 1003 rotates to above the material barrel discharge port 0905, the corresponding pull plate 1004's pull tongue block groove 1004A just locks the pull tongue block 0903A of the pull plate pull tongue block 0903. The guide rod cylinder 0902 actuates to pull the pull plate 1004 out of the pull plate limit seat 1002, exposing the material tube discharge hole 1002A. The buffer area feed valve 1901 opens, and the sodium rod in the bullet clip tube 1003 passes through the material tube discharge hole 1002A and the material barrel discharge port 0905. The sodium rod falls into the buffer tube 1902. The guide rod cylinder 0902 actuates to push the pull plate 1004 back into the pull plate limit seat 1002 to reset. The buffer zone feed valve 1901 closes and the buffer zone discharge valve 1903 opens. The sodium rod is put into the reactor 01. The buffer zone discharge valve 1903 is closed. The buffer unit inert gas replacement system 21 is used to replace the nitrogen gas 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 clip tube 1003 to rotate, so that the other bullet clip tube 1003 is located above the material barrel drop port 0905. The feeding is completed in the above manner.
