Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a reaction vessel for safe chemical production. Background Technology

[0002] Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization and condensation. Examples include reactors, reaction vessels, decomposition vessels, polymerization vessels, etc. The materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel, Inconel) and other composite materials.

[0003] Currently, during the feeding process, clumped materials cannot be broken up. After falling into the reactor, they are prone to splashing and causing violent reactions on the liquid surface inside the reactor, which brings safety risks to the feeding process. At the same time, the scraper inside the reactor is in constant contact with the inner wall of the reactor, causing excessive wear between the scraper and the inner wall of the reactor, reducing its service life. Therefore, we have proposed a reactor for safe chemical production. Utility Model Content

[0023] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0024] Example: Figure 1-5As shown, this utility model discloses a reaction vessel for safe chemical production, including a support 1. A reaction vessel 2 is fixedly installed inside the support 1. A top cover 3 is detachably connected to the top of the reaction vessel 2. A feed inlet 4 is opened on one side of the top of the top cover 3. A feed pipe 5 is fixedly connected to the top of the feed inlet 4. A filter plate 6 is fixedly connected inside the feed pipe 5. Slide grooves 7 are opened on both sides of the inner wall of the feed pipe 5. Threaded rods 8 are provided inside both slide grooves 7. A micro motor 9 is fixedly installed on one side of the feed pipe 5, and the output end of the micro motor 9 is connected to the threaded rod 8 for transmission. A threaded block 10 is threadedly connected to the outer circumference of the threaded rod 8. A roller 11 is rotatably connected to one side of the threaded block 10.

[0025] A rotary motor 12 is fixedly installed on one side of the feed pipe 5. The output end of the rotary motor 12 is connected to a ball screw 13. A connecting seat 14 is threadedly connected to the outer circumference of the ball screw 13. A partition 15 is fixedly welded to one side of the connecting seat 14 via a connecting rod. By setting the ball screw 13, the rotation of the ball screw 13 drives the connecting seat 14 to move, so that the partition 15 can block and lower inside the feed pipe 5, control the speed at which materials are added to the reactor 2, and improve the safety of material addition.

[0026] Among them, a drive motor 16 is fixedly installed on one side of the top of the top cover 3. The output end of the drive motor 16 is connected to a drive gear 17. The outer periphery of the drive gear 17 is connected to a driven gear 171 through a gear belt 18. A rotating shaft 19 is fixedly connected inside the driven gear 171. A sliding column 20 is fixedly welded to the outer periphery of the rotating shaft 19. By setting the drive gear 17, the rotating shaft 19 is rotated through the cooperation of the gear belt 18 and the driven gear 171. The push rod 28 inside works with the sliding column 20 and the sliding column 22 to carry out compound and thorough stirring of the materials inside the reactor 2, which helps to promote the chemical mixing reaction.

[0027] The reactor 2 has a support frame 21 fixedly connected to its lower interior. The top of the support frame 21 is rotatably connected to a second sliding column 22. Both ends of the second sliding column 22 are fixedly connected to a first sliding column 20 via a limiting plate 23. Sliding blocks 24 are slidably connected to the outer periphery of both the first sliding column 20 and the second sliding column 22. A scraper 25 is fixedly connected to one end of the sliding block 24. A cleaning brush is provided on one side of the scraper 25. By setting the scraper 25 and driving the push rod 28 to slide, the scraper 25 moves along the first sliding column 20 and the second sliding column 22, allowing the scraper 25 to be switched between stirring or cleaning at any time. This avoids collisions or other forms of injury to the hands and helps to improve the safety of the reactor operation.

[0028] Among them, a rotating rod 26 is rotatably connected to the center end of one side of the scraper 25, and a cylinder 27 is rotatably connected inside the rotating shaft 19. A push rod 28 is fixedly connected to the outer periphery of the bottom of the cylinder 27, and the center ends of both sides of the push rod 28 are rotatably connected to the rotating rod 26. By setting the cylinder 27, the cylinder 27 can be rotated by the limiting frame 29, so that the scraper 25 moves along the sliding column 1 20 and sliding column 22, so that the scraper 25 can be switched to stirring or cleaning at any time.

[0029] The cylinder 27 has a fixedly welded limit frame 29 on its top. A limit post 30 is slidably connected to one side of the limit frame 29. A spring 31 is sleeved on the outer periphery of the limit post 30. A force plate 32 is fixedly welded to the center end of the limit post 30. The upper part of the force plate 32 is fixedly connected to the spring 31. By setting the spring 31, the limit post 30 can be squeezed by pulling the force plate 32, causing the limit post 30 to move out of the limit hole 35, thus canceling the limit on the cylinder 27. This allows the cylinder 27 to rotate, causing the scraper 25 to move along the sliding column 1 20 and sliding column 22, so that the scraper 25 can be switched at any time for stirring or cleaning.

[0030] The lower end of the reactor 2 is fixedly connected to the discharge pipe 33, and the outer periphery of the discharge pipe 33 is provided with the discharge valve 34. The top of the rotating shaft 19 is provided with a limit hole 35. By setting the limit hole 35, the limit column 30 can be rotated to different angles, which in turn drives the scraper 25 to adjust the angle.

[0031] Working Principle: During operation, material is placed into the feed pipe 5. The micro motor 9 is activated, and its output drives the threaded rod 8 to rotate, causing the threaded block 10 to move the roller 11. The roller 11 effectively presses and filters the material, preventing uneven reaction. Then, the rotary motor 12 is activated, and its output drives the ball screw 13 to rotate, causing the connecting seat 14 to move the partition 15. The partition 15 blocks and lowers the filtered material inside the feed pipe 5, controlling the rate at which material is added to the reactor 2 and improving safety. Pulling the force plate 32 causes the limiting post 30 to compress the spring 31, causing the limiting post 30 to move out of the limiting hole 35, releasing the limit on the cylinder 27. This allows the cylinder 27 to rotate, causing the scraper 25 to move along the sliding column 20 and sliding column 20. 22. Switch the scraper 25 to stirring mode at any time, then release the force plate 32. Through the elastic force of the spring 31, place the limiting post 30 in the limiting hole 35 to limit the cylinder 27. Then start the drive motor 16. The output end of the drive motor 16 drives the drive gear 17 to rotate. Through the cooperation of the gear belt 18 and the driven gear 171, the rotating shaft 19 inside the driven gear 171 rotates. The internal push rod 28 works with the sliding column 1 20 and sliding column 22 to carry out compound and thorough stirring of the material inside the reactor 2, which helps to promote the chemical mixing reaction. After stirring is completed, the stirred material is discharged through the discharge pipe 33 through the discharge valve 34. The scraper 25 can be slid along the sliding column 1 20 and sliding column 22 again by rotating the limiting frame 29, so that the cleaning brush can be closely attached to the inner wall of the reactor 2 for cleaning.
