[0002] Reactor is a kind of pressure vessel commonly used in chemical enterprises, which is often used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, condensation, etc. It is generally made of carbon manganese steel, stainless steel, zirconium, nickel-based (Hastelloy, Monel, Inconel) alloy and other composite materials, and the material is required to have good heat resistance and corrosion resistance.

[0003] In the existing reactor, when materials are mixed and reacted in the reactor body, the materials are easy to stick to the inner wall of the reactor, which is inconvenient to clean up later. In addition, the form of directly feeding materials at the reactor inlet easily concentrates the feeding effect, which may make some reactions too intense. Utility Model Content

[0005] The stirring structure comprises a motor mounted on the upper surface of the kettle body, a rotating shaft is mounted on the motor, the rotating shaft rotates and penetrates the upper surface of the kettle body, and a stirring rod is mounted on the side wall of the rotating shaft;

[0006] A cross bar is installed on both sides of the rotating shaft, and a first scraper is vertically installed on the cross bar away from the rotating shaft end, and the first scraper is slidably connected to the inner wall of the kettle body;

[0007] A second scraper rod is installed at the bottom end of the rotating shaft, and the second scraper rod is slidably connected to the lower wall of the kettle body.

[0008] Preferably, a three-way pipe is provided on the feed port.

[0009] Preferably, the opening end of the three-way pipe away from the feed inlet is a curved structure, and the opening is curved upward.

[0010] Preferably, the first scraper rod and the cross bar are connected via a reinforcing rod.

[0011] Preferably, a discharge port is provided on the lower wall of the bend of the three-way pipe.

[0012] The utility model has the following beneficial effects: the utility model has a reasonable structure and a novel design. When in use, the material is injected into the three-way pipe from the feed port, and the material is discharged from the other two ends of the three-way pipe to be diverted, so that the material enters the kettle body in a dispersed manner, avoiding concentrated entry of the material, facilitating mixing, and slowing down the material to avoid the material directly impacting the inside of the kettle body. The material in the kettle body is stirred by the stirring structure, and the inner wall of the kettle body can be scraped by the first scraper and the second scraper to avoid the material sticking to the inner wall of the kettle body.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-2 A reaction kettle comprises a kettle body 1, a discharge port is arranged on the lower wall of the kettle body 1, a feed port 2 is arranged on the kettle body 1, and a stirring structure is arranged inside the kettle body 1, and the kettle body 1 is stirred by the stirring structure to accelerate the mixing of materials;

[0018] The stirring structure includes a motor 3 mounted on the upper surface of the kettle body 1, a rotating shaft 4 is mounted on the motor 3, the rotating shaft 4 rotates and penetrates the upper surface of the kettle body 1, and a stirring rod 5 is mounted on the side wall of the rotating shaft 4;

[0019] The motor 3 drives the rotating shaft 4 to rotate, thereby driving the stirring rod 5 to rotate, and the material is stirred by the rotation of the stirring rod 5;

[0020] A cross bar 6 is installed on both sides of the rotating shaft 4, and a first scraper 7 is vertically installed at the end of the cross bar 6 away from the rotating shaft 4. The first scraper 7 is connected to the cross bar 6 through a reinforcing rod 10 to strengthen the connection between the first scraper 7 and the cross bar 6. The first scraper 7 is slidably connected to the inner wall of the kettle body 1;

[0021] When the rotating shaft 4 rotates, the cross bar 6 rotates accordingly, thereby causing the first scraper 7 to rotate. When the first scraper 7 rotates, the side wall of the kettle body 1 can be scraped to prevent the material from sticking to the side wall of the kettle body 1;

[0022] A second scraper 8 is installed at the bottom end of the rotating shaft 4, and the second scraper 8 is slidably connected to the lower wall of the kettle body 1;

[0023] When the rotating shaft 4 rotates, the second scraper 8 rotates accordingly, and the second scraper 8 scrapes the lower wall of the kettle body 1 to prevent the material from sticking to the lower wall of the kettle body 1;

[0024] A tee pipe 9 is provided on the feed port 2. The opening end of the tee pipe 9 away from the feed port 2 is a curved structure, and the opening is curved upward. A discharge port 11 is provided on the lower wall of the curved portion of the tee pipe 9.

[0025] When material is added into the kettle body 1 through the feed port 2, the material enters the tee pipe 9 and is discharged from the other two ends of the tee pipe 9. Since the outlets at the other two ends of the tee pipe 9 are bent upward, the discharge of the material from the tee pipe 9 can be slowed down, avoiding the material from directly hitting the inside of the kettle body 1, and the material at the bend can be discharged through the provided discharge port 11.

[0026] Embodiment: When in use, the material is injected into the three-way pipe 9 from the feed inlet 2, and the material is discharged from the other two ends of the three-way pipe 9 to be diverted so that the material is dispersed and enters the kettle body 1 to facilitate mixing. The material can be slowed down to prevent the material from directly impacting the inside of the kettle body 1. The material in the kettle body 1 is stirred by the stirring structure, and the inner wall of the kettle body 1 can be scraped by the first scraper 7 and the second scraper 8 to prevent the material from sticking to the inner wall of the kettle body 1.
