Description

Technical Field

[0001] This utility model relates to the field of antioxidant technology, and in particular to a feed antioxidant reaction vessel. Background Technology

[0002] Traditional paddle agitation methods may not ensure sufficient contact between antioxidants and feed within the reactor. For example, simple paddle agitation can easily create dead zones when processing high-viscosity feed ingredients or mixtures containing a large amount of solid particles, preventing some materials from participating in the reaction. Furthermore, poor reactor sealing can allow air to enter, causing unnecessary reactions between antioxidants and oxygen during the reaction process, thus reducing the activity of the antioxidants. Based on these considerations, a feed antioxidant reactor was designed. Utility Model Content

[0003] To overcome at least one of the defects described in the prior art, this utility model provides a feed antioxidant reaction vessel. A first stirring structure pushes the material from the vessel wall towards the center and bottom, while a second stirring structure generates strong radial and axial flows. The combination of these two structures creates a complex flow within the vessel, improving the mixing effect. Furthermore, a nitrogen inlet allows air to be expelled from the reaction vessel, maintaining a slight positive pressure inside the vessel during the reaction process to prevent air from entering.

[0004] The technical solution adopted by this utility model to solve its problem is:

[0005] A feed antioxidant reactor includes: a reactor body, the interior of which is hollow to form a containment space, and the top of the reactor body is open; a lid, which covers the top opening of the reactor body; a first stirring structure, which is assembled within the containment space and is used to push materials from the side wall of the reactor body towards the center and bottom; a second stirring structure, which is assembled within the containment space and is used to drive the materials to flow radially and mix; and a nitrogen inlet, which is opened on the lid and is used to introduce nitrogen into the reactor body.

[0006] By adopting the above scheme, the first stirring structure can push the material from the vessel wall to the center and bottom, and the second stirring structure can generate strong radial and axial flow. The combination of the two makes the material form a complex flow in the vessel, improving the mixing effect. The nitrogen inlet can also be used to expel air from the reactor body, maintaining a slight positive pressure inside the vessel during the reaction process to prevent air from entering.

[0007] Further, the first stirring structure includes: a first stirring shaft; a scraper plate, the scraper plate being sleeved on the outer surface of the stirring shaft; a first stirring blade, the first stirring blade being assembled between the scraper plate and the first stirring shaft, and the first stirring blade being fixedly connected to the scraper plate; and a second stirring blade, the second stirring blade being sleeved on the outer surface of the first stirring shaft.

[0008] By adopting the above method, the scraping and stirring effects of the vessel wall can be achieved.

[0009] Furthermore, the second stirring structure includes: a second stirring shaft; and a stirring paddle, the stirring paddle being sleeved on the outer surface of the second stirring shaft.

[0010] By adopting the above method, the stirring effect can be achieved.

[0011] Furthermore, the agitator is a turbine-type agitator.

[0012] By adopting the above scheme, the turbine impeller can generate strong radial and axial flow.

[0013] Furthermore, the first stirring shaft and the second stirring shaft are integrally formed.

[0014] By adopting the above solution, the one-piece molded structure is stable.

[0015] Furthermore, the reactor lid is provided with a feed inlet communicating with the containment space, the reactor body is provided with a discharge outlet communicating with the containment space, the feed inlet is covered with a sealing cap, and the discharge outlet is provided with a valve.

[0016] By adopting the above scheme, feed antioxidants can be easily added into the reactor through the discharge port, and can also be easily discharged through the discharge port. Furthermore, valves can be installed to facilitate the smooth flow of materials.

[0017] Furthermore, it also includes a support structure for reserving space between the reactor body and the ground.

[0018] By adopting the above scheme, the stability of the support is improved by setting up a support structure, and space is reserved between the reactor body and the ground to facilitate material discharge from the outlet.

[0019] Furthermore, a drive motor is mounted on the top of the vessel lid, and the output shaft of the drive motor is connected to the first stirring shaft.

[0020] By adopting the above scheme, the first and second stirring shafts are rotated by a drive motor, thereby achieving the mixing effect of materials. Attached Figure Description

[0029] See Figures 1-3This utility model discloses a feed antioxidant reactor: it includes a reactor body 1, a lid 2, a first stirring structure, a second stirring structure, and a nitrogen inlet 5. The reactor body 1 is hollow inside, forming a containment space. The top of the reactor body 1 is open, and the lid 2 is placed over the open top of the reactor body 1 and is fixed to the reactor body 1 by a ring of bolts. The first stirring structure is assembled in the containment space and is used to push the material from the side wall of the reactor body 1 towards the center and bottom. The second stirring structure is assembled in the containment space and is used to drive the material to flow radially and mix. The first stirring structure is positioned above the second stirring structure. The first stirring structure pushes the material from the reactor wall towards the center and bottom, while the second stirring structure generates strong radial and axial flows. The combination of these two structures creates a complex flow within the reactor, improving the mixing effect.

[0030] The reactor body 1 is cylindrical in shape and made of carbon steel.

[0031] In this embodiment, the nitrogen inlet 5 is located on the vessel cover 2, and is used to introduce nitrogen gas into the reactor body 1. The nitrogen inlet 5 allows air to be expelled from the reactor body 1, maintaining a slight positive pressure inside the vessel during the reaction process and preventing air from entering. Specifically, the nitrogen inlet 5 is connected to a nitrogen source via a pipe, facilitating the introduction of nitrogen gas into the containment space through the pipe. In this embodiment, it is preferable to maintain a slight positive pressure of 0.05-0.1 MPa inside the reactor body 1.

[0032] In some embodiments, a support structure 6 is also provided.

The second stirring blade 34 is sleeved on the outer surface of the first stirring shaft 31. This achieves the scraping and stirring effects of the vessel wall.

[0034] In this embodiment, the second stirring structure includes a second stirring shaft 41 and a stirring paddle 42. The stirring paddle is fitted onto the outer surface of the second stirring shaft 41 to achieve the stirring effect. Specifically, the stirring paddle 42 is a turbine-type stirring paddle 42, which can generate strong radial and axial flows.

[0035] In this embodiment, a drive motor 7 is mounted on the top of the vessel lid 2. The output shaft of the drive motor 7 is connected to the first stirring shaft 31. The drive motor 7 drives the first stirring shaft 31 and the second stirring shaft 41 to rotate, thereby achieving the mixing effect of materials. The first stirring shaft 31 and the second stirring shaft 41 are integrally formed, and the integrally formed structure is stable.

[0036] The reactor lid 2 has a feed inlet 21 communicating with the containment space, and the reactor body 1 has a discharge outlet 11 communicating with the containment space. A sealing cap 211 covers the feed inlet 21, and a valve 111 is installed at the discharge outlet 11. The discharge outlet 11 facilitates the addition of feed antioxidants into the reactor and allows for easy discharge. More specifically, the valve 111 is a butterfly valve. The sealing cap 211 is hinged to the feed inlet 21.

[0037] The working principle and steps of this utility model are as follows: When in use, open the sealing cover 211 and put the material in through the feed port 21. The reaction vessel body 1 is kept under a slight positive pressure through the nitrogen inlet 5.
