Description

Technical Field

[0001] This utility model relates to reactor feeding, and in particular to a solid feeding reactor, belonging to the field of reactor feeding technology. Background Technology

[0002] A solid feed reactor is a type of reactor used to add solid substances into a chemical reaction process. Its main function is to accurately and stably deliver solid raw materials into the reactor through a feeding device, ensuring full contact with the reaction medium, thereby enabling the chemical reaction to take place.

[0003] CN215277219U discloses a solid material feeder for a reactor, relating to the field of feeding device technology. It includes a feeding hopper, with an L-shaped rod fixedly connected to the outer left side of the hopper. A fixed plate is connected to the top of the L-shaped rod, and a rotating shaft is movably connected to the bottom right side of the fixed plate. A cover plate is connected to the bottom of the rotating shaft. This invention includes a vent pipe, a slider, a nozzle, and a spring. The vent pipe is connected to an air pump, and the nozzle sprays compressed gas to clean the inner wall of the feeding hopper. The gas spray pushes the slider and nozzle to the right, thus compressing the spring. When the compressed air supply stops, the slider moves to the left under the spring force. This process repeats, effectively cleaning the inner wall of the feeding hopper. This results in a relatively dry feeding hopper after cleaning, preventing material from sticking to the inner wall during subsequent feeding and thus not affecting the feeding process.

[0004] However, during the feeding process, the gas inside the reactor inevitably escapes. If highly reactive or explosive gases are generated during the reaction, the risk of explosion or fire may increase, thus requiring improvement.

[0005] Therefore, a solid feed reactor is proposed. Utility Model Content

[0033] Example 1

[0034] like Figures 1-8 As shown, this embodiment of the present invention provides a solid feeding reactor, including...

[0035] The main structure includes a reaction tank 1, a discharge valve 2, a liquid inlet pipe 3, a constant pressure pipe 4, a top cover 5, a motor 6, a rotating shaft 7, a stirring head 8, a bearing seat 9, and a solid feed inlet 10.

[0036] Gas escape prevention mechanism, including cavity plate 11, cylinder 12, hollow slider 13, feed hopper 14, air pump 15, air extraction pipe 16, air extraction head 17, air delivery pipe 18, cover plate 19, frame plate 20, rotating rod 21, fixing block 22, butterfly anti-reverse plate 23, and torsion spring 24.

[0037] The wall scraping mechanism includes an upper support plate 25, a lower support plate 26, a T-slot 27, a slot 28, a bolt 29, an insert plate 30, a scraper 31, and a T-block 32.

[0038] In one embodiment, the discharge valve 2 is located at the bottom of the reaction tank 1, the liquid inlet pipe 3 is connected to the top of the reaction tank 1 via a flange, the constant pressure pipe 4 is connected to the top of the reaction tank 1 via a flange, the top cover 5 is connected to the top of the reaction tank 1 via a flange, the motor 6 is fixedly installed on the top of the top cover 5, the rotating shaft 7 is fixedly installed on the output end of the motor 6, the stirring head 8 is circumferentially fixedly installed on the surface of the rotating shaft 7, the bearing seat 9 is fixedly installed on the bottom of the inside of the reaction tank 1, the solid feed inlet 10 is opened on the top of the top cover 5, the cavity plate 11 is fixedly installed on the top of the top cover 5, the cylinder 12 is fixedly installed on the side of the cavity plate 11, the hollow slider 13 slides inside the cavity plate 11 and is fixedly installed on the output end of the cylinder 12, the feed hopper 14 is located on the top of the cavity plate 11, and the vacuum pump 15 is fixedly installed on the surface of the top cover 5. The suction head 17 is embedded inside the cavity plate 11. One end of the suction pipe 16 is connected to the suction end of the suction pump 15, and the other end of the suction pipe 16 is connected to the suction head 17. One end of the air supply pipe 18 is connected to the air supply end of the suction pump 15, and the other end of the air supply pipe 18 is fixed to the bottom end of the top cover 5. The cover plate 19 is hinged to the surface of the feed hopper 14. The frame plate 20 is fixedly installed inside the cover plate 19. The rotating rod 21 rotates inside the frame plate 20. The fixing block 22 is fixedly installed on the surface of the rotating rod 21. A torsion spring 24 is sleeved on the surface of the rotating rod 21. One end of the torsion spring 24 is fixedly installed on the inner wall of the frame plate 20, and the other end of the torsion spring 24 is fixedly installed on the surface of the fixing block 22. The butterfly anti-reverse plate 23 is fixedly installed on the surface of the fixing block 22. The torsion spring 24 drives the butterfly anti-reverse plate 23 to tend to move away from the feed hopper 14. For highly reactive or explosive gases such as hydrogen and methane, preventing their escape can reduce the risk of explosion or fire and ensure the safety of the entire operation process. At the same time, if harmful gases are generated in the reactor, preventing their escape helps to ensure the safety of operators and reduce the risk of toxic and harmful gases to human health.

[0039] Example 2

[0040] like Figure 1 , Figures 4-6 As shown, the upper support plate 25 and the lower support plate 26 are both fixedly installed on the surface of the rotating shaft 7. The T-slot 27 is opened on the inner side of the lower support plate 26, and the slot 28 is opened on the inner side of the upper support plate 25. The inner side of the upper support plate 25 is threaded with a bolt 29, and the inner side of the slot 28 is inserted with a plate 30. A scraper 31 is fixedly installed on the surface of the plate 30, and a T-block 32 is fixedly installed on the back of the scraper 31. When the rotating shaft 7 rotates, it will drive the upper support plate 25, the lower support plate 26, and the scraper 31 to rotate together, thereby scraping off the residue on the inner wall of the reaction vessel 1 to achieve the best mixing reaction effect.

[0041] Example 3

[0042] like Figures 1-8As shown, the cavity plate 11 is fixedly installed above the solid feed inlet 10 in a covering shape; this arrangement, together with the hollow slider 13, can effectively reduce gas escape and improve operational safety; a through groove is opened on the inner side of the hollow slider 13. The cylinder 12 pushes the hollow slider 13 along the cavity plate 11 until the through groove of the hollow slider 13 is aligned with the solid feed inlet 10. At this time, under the action of gravity, the solid material inside the through groove will fall into the inner side of the reaction tank 1, thereby completing the feeding task.

[0043] The insert plate 30 is fixedly installed inside the slot 28 by bolts 29. The position of the insert plate 30 inside the slot 28 can be controlled by screwing in or out the bolts 29.

[0044] The T-slot 27 is adapted to the T-block 32. The cooperation between the T-slot 27 and the T-block 32 can achieve excellent limiting effect, prevent shaking, and ensure high stability.

[0045] In operation, when feeding solid materials, the present invention first activates the cylinder 12, causing the hollow slider 13 to slide along the cavity plate 11, so that the through groove of the hollow slider 13 is perpendicularly aligned with the feed hopper 14. Then, the vacuum pump 15 is activated, and the gas inside the through groove is quickly extracted through the vacuum pipe 16 and the vacuum head 17. During this process, a negative pressure is formed inside the through groove. Under the action of the negative pressure, the butterfly-shaped check plate 23 rotates downwards along the rotating rod 21, thereby guiding outside air into the feed hopper 14 and the inside of the through groove, and preventing internal air leakage. Gas escapes, and the extracted gas will return to the interior of the reaction vessel 1 through the extraction pipe 16 and the gas delivery pipe 18. When the gas pressure inside the channel gradually stabilizes, the butterfly check plate 23 will be reset under the action of the torsion spring 24. Then, the cover plate 19 can be opened and the solid material can be put into the feed hopper 14. Under the action of gravity, the solid material will fall into the channel of the hollow slider 13. Then, the cylinder 12 is activated to push the hollow slider 13 along the cavity plate 11 until the channel of the hollow slider 13 is aligned with the solid feed port 10. Under the influence of gravity, the solid material inside the channel falls to the inside of the reaction tank 1, thus completing the feeding task and preventing the escape of gas inside the reaction tank 1. The motor 6 is started, driving the rotating shaft 7 to rotate, which in turn drives the stirring head 8 to stir and promote the reaction inside the reaction tank 1. Simultaneously, the rotating shaft 7 drives the upper support plate 25, lower support plate 26, and scraper 31 to rotate together, thereby scraping off the residual material on the inner wall of the reaction tank 1 to achieve the best mixing reaction effect. The scraper 31 needs to be replaced. During installation, first remove the top cover 5 by disassembling the flange to expose the internal scraper 31. Then, turn the bolt 29 to unscrew it, thereby releasing the limiting effect of the insert plate 30 inside the slot 28. Next, pull the scraper 31 upward to pull the insert plate 30 out from the inside of the slot 28 and the T-block 32 out from the inside of the T-slot 27. During installation, align the T-block 32 and the insert plate 30 with the T-slot 27 and the slot 28 respectively and insert them from top to bottom. Finally, screw in the bolt 29 to complete the installation of the scraper 31.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
