Description

Technical Field

[0001] This utility model relates to the field of chemical production technology, specifically a chemical safety feeding device. Background Technology

[0002] Chemical production refers to the process of chemically processing raw materials to ultimately obtain valuable products. In chemical production, materials need to be fed into reaction vessels for chemical reactions. This is especially true when feeding solid materials; some chemical reactions require multiple additions of materials when transporting them into the reaction vessel, increasing the workload for workers. Furthermore, the continuous feeding necessitates constantly opening the top cover of the reaction vessel, leading to excessive dust generation and impacting the surrounding environment. Currently, the fact that the feed inlet is located at the top of the reaction vessel also adds extra work and inconveniences workers during feeding. Utility Model Content

[0003] In order to solve the above problems, the purpose of this utility model is to provide a chemical safety feeding device.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a chemical safety feeding device, including a reaction vessel, a feed pipe installed on the top of the reaction vessel, an inclined feed plate fixedly installed at the upper end of the feed pipe, an inclined discharge plate fixedly installed inside the feed pipe, a horizontally arranged baffle at the bottom of the discharge plate inside the feed pipe, a horizontally arranged long plate fixedly installed at the end of the baffle away from the bottom of the discharge plate, a first swing plate rotatably installed at the end of the long plate away from the baffle, a second swing plate rotatably installed at the end of the first swing plate away from the long plate, a first rotating rod fixedly installed at the end of the second swing plate away from the first swing plate, a support plate fixedly installed on the outside of the feed pipe near the long plate, and the first rotating rod rotatably installed on the support plate.

[0005] Preferably, a fixing plate is installed on the side wall of the reactor, and an inclined feeding pipe is fixed on the fixing plate. A spiral conveying roller is installed inside the feeding pipe, and a drive motor is installed at the top of the feeding pipe. The output end of the drive motor is coaxially fixed on the spiral conveying roller. The top of the feeding plate is fixed at the top of the feeding pipe, and a feeding hopper is installed at the bottom of the feeding pipe.

[0006] Preferably, an inclined vibrating plate is fixedly installed inside the feed pipe on the back of the discharge plate, and a U-shaped bracket is fixedly installed on the side of the vibrating plate away from the discharge plate. The two ends of the bracket movably pass through the feed pipe, and a horizontally arranged second rotating rod is rotatably installed on the outside of the feed pipe near the middle end of the bracket. A cam is fixed on the second rotating rod, and the top of the cam can abut against the bracket.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. The spiral conveying roller in this utility model can easily transport materials to the feed inlet at the top of the reactor. Subsequently, the first rotating rod, the first swing plate, the second swing plate, the long plate and the baffle can make the materials above the feed pipe intermittently fed, eliminating the need for workers to add materials repeatedly, reducing the workload of workers, and the baffle can also prevent dust from affecting the surrounding environment during feeding.

[0009] 2. In this utility model, the second rotating rod can drive the cam to make the vibrating plate strike the feeding plate, so that the material on the feeding plate can be vibrated and fall, avoiding adhesion to the feeding plate and improving the integrity of feeding.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-4 As shown, this utility model provides a chemical safety feeding device, including a reaction vessel 1. A feed pipe 11 is installed on the top of the reaction vessel 1. An inclined feed plate 12 is fixedly installed at the upper end of the feed pipe 11. An inclined discharge plate 13 is fixedly installed inside the feed pipe 11. A horizontally arranged baffle 14 is provided at the bottom of the discharge plate 13 inside the feed pipe 11. A horizontally arranged long plate 15 is fixedly installed at the end of the baffle 14 away from the bottom of the discharge plate 13. The end of the long plate 15 away from the baffle 14 passes through the feed plate 12 and is rotatably provided with a first swing plate 16. A second swing plate 17 is rotatably provided at the end of the first swing plate 16 away from the long plate 15. A first rotating rod 18 is fixedly provided at the end of the second swing plate 17 away from the first swing plate 16. A support plate 19 is fixedly installed on the outside of the feed pipe 11 near the long plate 15. The first rotating rod 18 is rotatably mounted on the support plate 19.

[0018] A fixing plate 4 is installed on the side wall of the reactor 1. An inclined feeding pipe 41 is fixed on the fixing plate 4. A spiral conveying roller 42 is installed inside the feeding pipe 41. A drive motor 43 is installed on the top of the feeding pipe 41. The output end of the drive motor 43 is coaxially fixed on the spiral conveying roller 42. The top of the feed plate 12 is fixed on the top of the feeding pipe 41. A feed hopper 44 is installed at the bottom of the feeding pipe 41. The drive motor 43 can drive the spiral conveying roller 42 to rotate, so that the material input through the feed hopper 44 can be conveyed into the feed pipe 11 to complete the feeding. The feeding pipe 41 and the spiral conveying roller 42 can be used for conveying without the need for workers to climb to the relatively high feed inlet of the reactor 1 to feed the material, which greatly reduces the workload of workers and improves the convenience and safety of operation.

[0019] An inclined vibrating plate 2 is fixedly installed inside the feed pipe 11 on the back of the unloading plate 13. A U-shaped bracket 21 is fixedly installed on the side of the vibrating plate 2 away from the unloading plate 13. Both ends of the bracket 21 movably pass through the feed pipe 11. A horizontally arranged second rotating rod 24 is rotatably installed on the outside of the feed pipe 11 near the middle end of the bracket 21. A cam 23 is fixedly installed on the second rotating rod 24. The top of the cam 23 can abut against the bracket 21. When the second rotating rod 24 drives the cam 23 to rotate, the cam 23 will abut against the bracket 21, thereby pushing the bracket 21 and causing the vibrating plate 2 to move towards the unloading plate 13. The vibrating plate 2 strikes the feeding plate 13, causing the material on the feeding plate 13 to fall due to vibration, preventing it from adhering to the feeding plate 13 and improving the integrity of the feeding process. Springs 22 are fitted at both ends of the support 21 outside the feed pipe 11. The two ends of the springs 22 are fixedly mounted on the support 21 and the feed pipe 11, respectively. The springs 22 allow the support 21 to push the vibrating plate 2 to strike the feeding plate 13 and then reset, waiting for the next push of the cam 23. This repeated action continuously strikes the feeding plate 13, allowing the material on the vibrating plate 2 to fall fully for feeding.

[0020] A connecting shaft 3 is rotatably mounted on the support plate 19. A small gear 32 is fixedly mounted on the end of the second rotating rod 24. A large gear 31, meshing with the small gear 32, is fixedly mounted on the connecting shaft 3. By setting the large gear 31 to drive the small gear 32 to rotate, the second rotating rod 24 can have a faster rotation speed, thereby increasing the rate at which the vibrating plate 2 strikes the material discharge plate 13, making the material discharge from the material discharge plate 13 more complete and effective. A drive motor 34 is fixedly mounted on the outside of the feed pipe 11 near the connecting shaft 3. The output end of the drive motor 34 is coaxially fixed on the connecting shaft 3. The drive motor 34 can provide power for the rotation of the connecting shaft 3, thereby giving the first rotating rod 18 and the second rotating rod 24 sufficient power to rotate and work. A belt 33 is provided between the connecting shaft 3 and the first rotating rod 18. The belt 33 is connected to the first rotating rod 18 and the connecting shaft 3 through a transmission wheel. The belt 33 can make the first rotating rod 18 and the second rotating rod 24 rotate together, increasing the linkage of the device.

[0021] Working principle: In actual use, the material input through the feed hopper 44 is fed into the feed plate 12 and feed pipe 11 by the screw conveyor roller 42 to complete the feeding. At this time, the material can accumulate in the space isolated by the discharge plate 13, specifically located above the inside of the feed pipe 11, and is blocked by the discharge plate 13 and the baffle 14. When more material needs to be added, the drive motor 34 can be started. The drive motor 34 can drive the connecting shaft 3 to rotate. At this time, the belt 33 can drive the first rotating rod 18 to rotate. The first rotating rod 18 will drive the second swing plate 17 to rotate. At this time, the second swing plate 17, together with the first swing plate 16, will pull the long plate 15 away from the discharge plate 13 to complete the feeding process. Figure 2 As shown, the material fed into the feed pipe 11 will fall into the reaction vessel 1 below, completing the feeding process. At the same time, as the first rotating rod 18 continuously drives the second swing plate 17 to move the first swing plate 16, the first swing plate 16 will continuously drive the long plate 15 to move back and forth, so that the long plate 15 controls the baffle 14 to intermittently open the opening at the bottom of the feeding plate 13, so that the material above the feed pipe 11 is fed intermittently, eliminating the need for the staff to add material multiple times, reducing the workload of the staff, and the baffle 14 can also prevent dust from affecting the surrounding environment during feeding.

[0022] Simultaneously, when the connecting shaft 3 rotates, the second rotating rod 24 can be driven to rotate through the large gear 31 and the small gear 32. At this time, the second rotating rod 24 drives the cam 23 to rotate. The cam 23 will abut against the bracket 21, thereby pushing the bracket 21 to move the vibrating plate 2 toward the feeding plate 13, so that the vibrating plate 2 knocks on the feeding plate 13, thereby causing the material on the feeding plate 13 to be vibrated and fall, avoiding adhesion to the feeding plate 13 and improving the integrity of feeding.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
