[0019] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0021] See also Figures 1 to 10 A titanium steel reactor provided by an embodiment of the present invention comprises a reactor body 1, on which a stirring assembly 2 for stirring is installed, the stirring assembly 2 comprises a rotating shaft 21, the rotating shaft 21 is located inside the reactor body 1 and the upper section penetrates the reactor body 1 and is rotatably connected thereto, a U-shaped stirring tube 22 located inside the reactor body 1 is installed on the rotating shaft 21, and the rotating shaft 21 is driven to rotate by a driving member; a heat exchange assembly 4, the heat exchange assembly 4 is installed above the reactor body 1 through a mounting frame 3, the heat exchange assembly 4 comprises a middle rotating cylinder 41, two cavities 42 distributed up and down are opened inside the middle rotating cylinder 41, and a An input pipe 43 and an output pipe 44 are respectively connected to the two cavities 42, two guide cavities 45 are vertically arranged side by side inside the rotating shaft 21, and the lower ends of the two guide cavities 45 are connected, two through ports 46 are respectively connected to the two guide cavities 45 on the side wall of the upper section of the rotating shaft 21, and the two cavities 42 are respectively connected to the two guide cavities 45 through the through ports 46, a docking port 47 connected to the guide cavities 45 is opened on the side wall of the rotating shaft 21, and the middle part of the docking port 47 is closed, the two ports of the U-shaped stirring tube 22 are respectively connected to the upper and lower ports of the docking port 47, and the upper section of the rotating shaft 21 passes through the middle rotating cylinder 41 and is rotatably connected thereto.

[0022] It should be noted that during the use of the reactor of the present invention, the reactants are placed in the reactor body 1 for reaction, and the rotating shaft 21 is driven to rotate by the driving member, which drives the U-shaped stirring tube 22 to rotate to stir the reactants in the reactor body 1 to fully mix the reaction and increase the reaction rate. When it is necessary to heat the reactants inside the reactor body 1, a hot fluid is input through the input pipe 43, and the hot fluid successively passes through the upper cavity 42 and the through port 46 into one of the guide cavities 45 opened inside the U-shaped stirring tube 22. When the hot fluid passes through the U-shaped stirring tube 22, since the middle part of the docking port 47 is closed, the hot fluid flows into the U-shaped stirring tube 22 and then re-enters the guide cavity 45. The U-shaped stirring tube 22 is U-shaped and hollow, and can be used as a U-shaped tube for the passage of hot fluid; the middle part of the docking port 47 is closed, and the hot fluid cannot directly enter from the opening The hot fluid does not directly pass through the guide cavity 45 of the interface 47, but uses the U-shaped tube as a transfer station to guide the hot fluid. The hot fluid finally enters the cavity 42 located below, and then flows out through the output pipe 44, completing a heating operation of the reactants inside the reactor body 1. The hot fluid enters the heating device and is heated again before entering the reactor body 1 to continuously heat the reactants therein; in the present invention, the hot fluid is introduced into the rotating shaft 21 and the U-shaped stirring tube 22 through the heat exchange component 4 to continuously exchange heat with the reactants inside the reactor body 1. The rotating shaft 21 continuously exchanges heat with the center of the reactants, and the U-shaped stirring tube 22 continuously stirs and rotates, and will contact the reactants at different levels, and perform multi-level heat exchange on the reactants, ensuring that the heat exchange effects of each level of the reactants are roughly consistent, thereby improving the heat exchange efficiency and ensuring the reaction quality of the reactants.

[0023] Among them, the heat exchange component 4 is also suitable for continuous cooling of the reactants; when the shaft 21 rotates, the opening direction of the through port 46 rotates accordingly, and the middle rotating cylinder 41 does not move. Since the reactants need to be stirred at a slow speed, that is, the shaft 21 rotates slowly, the fluid can smoothly pass through the through port 46 into the guide cavity 45 or flow from the guide cavity 45 into the cavity 42; in order to further improve the stirring and heat exchange effects of the reactants, the number and density of the U-shaped stirring tubes 22 can be set according to the situation.

[0024] In the embodiments of the present invention, please refer to Figure 1 and Figure 2 The reactor body 1 includes a tank body 11, a tank cover 12 is fixedly installed at the upper opening of the tank body 11, and a mounting frame 3 is fixedly installed on the upper side wall of the tank cover 12, a feed pipe 13 away from the mounting frame 3 is installed on the tank cover 12, a discharge pipe 14 is installed at the center of the lower side wall of the tank body 11, and a plurality of supporting frames 15 arranged around are fixedly installed at the lower end of the tank body 11.

[0025] It should be noted that: the tank body 11 and the tank cover 12 are connected by bolts or other sealing devices, and high-quality sealing rings, gaskets, etc. are used to ensure the sealing performance under high temperature and high pressure environment to prevent the gas and liquid generated by the reactants from leaking out. The feed pipe 13 is used to transport the reactants to the inside of the reactor body 1, and the discharge pipe 14 is used for the discharge operation of the reactants after the reaction. The support frame 15 is used for supporting the operation off the ground; The feed pipe 13 and the discharge pipe 14 are equipped with corresponding valves to control the inflow and outflow flow and flow direction of the materials.

[0026] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 as well as Figure 4 The driving member includes a driving motor 23, which is fixedly mounted on the top of the mounting frame 3, and a driving shaft 24 is fixedly mounted on the output end of the driving motor 23. The end of the driving shaft 24 away from the driving motor 23 passes through the mounting frame 3 and is connected to the upper end of the rotating shaft 21.

[0027] It should be noted that the driving motor 23 drives the driving shaft 24 to rotate, and the driving shaft 24 is connected to the upper end of the rotating shaft 21, so as to drive the rotating shaft 21 to rotate; The drive shaft 24 can be made of metal with good heat insulation and hardness that meets the standard, so as to avoid the heat exchange component 4 and perform heat exchange on the drive motor 23, thereby protecting the drive motor 23.

[0028] In the embodiments of the present invention, please refer to Figure 4 , Figure 5 as well as Fig. 9 The lower end of the driving shaft 24 is fixedly sleeved with a docking sleeve 241, and the lower end of the driving shaft 24 is fixedly installed with a docking block 243 located inside the docking sleeve 241, and the upper side wall of the rotating shaft 21 is provided with a docking slot 242 that is matched with the docking block 243, and a reinforcing bolt 244 for locking is installed on the side wall of the docking sleeve 241.

[0029] It should be noted that: when installing the driving member, the driving motor 23 is fixedly installed on the mounting frame 3, and the docking block 243 at the lower end of the driving shaft 24 is inserted into the docking slot 242 at the upper end of the rotating shaft 21 to achieve the preliminary docking of the driving shaft 24 and the rotating shaft 21. At the same time, the docking sleeve 241 is sleeved on the upper end of the rotating shaft 21, and the docking sleeve 241 is locked on the rotating shaft 21 by tightening the reinforcing bolt 244, so that the driving shaft 24 and the rotating shaft 21 are docked and fixed, and the docking is strong. The docking block 243 is located inside the docking sleeve 241 , and has the same shape as the docking slot 242 . The port of the docking block 243 is chamfered to facilitate insertion into the docking slot 242 .

[0030] In the embodiments of the present invention, please refer to Figure 3 and Figure 6 A plurality of groups of U-shaped stirring tubes 22 arranged vertically are installed on the side wall of the rotating shaft 21, and the number of each group of U-shaped stirring tubes 22 is four, and each group of four U-shaped stirring tubes 22 is arranged in a surrounding manner. The ends of two U-shaped stirring tubes 22 located on the same side of each group of four U-shaped stirring tubes 22 are fixedly connected with arc-shaped clamping plates 221, one side wall of the two arc-shaped clamping plates 221 is rotatably connected by a pin shaft, and the other side wall of the two arc-shaped clamping plates 221 is fixedly installed with ear pieces, and the two ear pieces are fixedly connected by locking bolts 222.

[0031] It should be noted that: the two arc-shaped clamping plates 221 are symmetrical and one end of the arc-shaped clamping plates 221 is rotatably connected by a pin shaft so that the two arc-shaped clamping plates 221 can be unfolded and closed. During the installation of the U-shaped stirring tube 22 and the rotating shaft 21, the two arc-shaped clamping plates 221 are closed and wrapped around the rotating shaft 21, so that the port of the U-shaped stirring tube 22 is aligned with the docking port 47 on the rotating shaft 21, and the ear piece on the other side of the arc-shaped clamping plate 221 is locked and fixed by the locking bolt 222, so that the two arc-shaped clamping plates 221 can be fixed on the rotating shaft 21, and the installation of the U-shaped stirring tube 22 is completed, that is, the U-shaped stirring tube 22 is detachable, which is convenient for the inspection and maintenance of the U-shaped stirring tube 22 and the guide cavity 45; Among them, see Figure 7 and Fig.10 A positioning block 223 is fixedly installed on the inner wall of the arc-shaped clamping plate 221, and a positioning hole 224 cooperating with the positioning block 223 is opened on the side wall of the rotating shaft 21. The positioning block 223 is inserted into the corresponding positioning hole 224, so that the arc-shaped clamping plate 221 can be positioned and installed, so that the cavity inside the U-shaped stirring tube 22 is accurately connected with the guide cavity 45, thereby improving the convenience of installation and docking accuracy of the U-shaped stirring tube 22; Among them, see Figure 7 A raised sealing gasket 225 is fixedly connected to the arc-shaped concave wall of the arc-shaped clamping plate 221. When the two arc-shaped clamping plates 221 are locked on the rotating shaft 21, the sealing gasket 225 seals the joint between the arc-shaped clamping plate 221 and the rotating shaft 21 through the slightly raised sealing gasket 225 to prevent the fluid from flowing out from the gap.

[0032] In the embodiments of the present invention, please refer to Figure 3 A plurality of arc scrapers 25 are fixedly mounted on the lower end of the rotating shaft 21 and are arranged around the lower end of the rotating shaft 21 , and the plurality of arc scrapers 25 are close to the inner bottom of the can body 11 .

[0033] It should be noted that when the rotating shaft 21 rotates, it drives the arc-shaped scraper 25 to stir the reactants at the bottom of the reactor body 1, so as to avoid the reactants from piling up at the bottom and failing to mix them fully, thereby increasing the reaction rate. It is worth noting that this is mainly for solid reactants, which accumulate at the bottom and are difficult to stir, resulting in poor mixing reaction effect.

[0034] In the embodiments of the present invention, please refer to Figure 1 , Figure 3 and Figure 8 A limiting sleeve 411 is installed on the upper and lower side walls of the rotating cylinder 41. A limiting sleeve 411 located below the rotating cylinder 41 is fixedly sleeved on the rotating shaft 21, and a limiting sleeve 411 located above the rotating cylinder 41 is sleeved on the rotating shaft 21 and locked on the rotating shaft 21 by a limiting bolt 412.

[0035] It should be noted that: when installing the central rotating cylinder 41, the mounting frame 3 is fixed to the upper end of the reactor body 1, and the central rotating cylinder 41 will be passed through the middle by the rotating shaft 21. One of the limiting sleeves 411 is located below the central rotating cylinder 41, and the central rotating cylinder 41 is supported and limited at the bottom. Then another limiting sleeve 411 is put on the rotating shaft 21 on the central rotating cylinder 41, and it is limited on the rotating shaft 21 by the limiting bolt 412, and the top of the central rotating cylinder 41 is limited, so that some heat exchange components 4 on the mounting frame 3 can be disassembled for inspection and maintenance.

[0036] In the embodiments of the present invention, please refer to Figure 3 and Figure 8 A transverse reinforcement rod 31 is installed inside the mounting frame 3, and the two ends of the reinforcement rod 31 are fixedly connected to the outer wall of the rotating cylinder 41 and the inner wall of the mounting frame 3 respectively; the connection between the rotating cylinder 41 and the mounting frame 3 is strengthened by the transverse reinforcement rod 31, thereby improving the stability of the rotating cylinder 41.

[0037] The working principle of the titanium steel reactor provided by the present invention is as follows: During use of the reactor of the present invention, the reactants are introduced into the reactor body 1 through the feed pipe 13 for reaction, and the driving motor 23 drives the driving shaft 24 to rotate, so that the driving shaft 21 drives the U-shaped stirring tube 22 to rotate, and the reactants in the reactor body 1 are stirred and fully mixed for reaction, thereby increasing the reaction rate. When it is necessary to heat the reactants inside the reactor body 1, a hot fluid is input through the input pipe 43, and the hot fluid sequentially passes through the upper cavity 42 and the through port 46 into one of the guide cavities 45 opened inside the U-shaped stirring tube 22. When the hot fluid passes through the U-shaped stirring tube 22, since the middle part of the docking port 47 is closed, the hot fluid flows into the U-shaped stirring tube 22 and then re-enters the guide cavity 45. The hot fluid finally enters the cavity 42 located below, and then passes through the output pipe 46. 44 flows out, and the hot fluid exchanges heat with the reactants in the reactor through the rotating shaft 21 and the U-shaped stirring tube 22, completing a heating operation for the reactants in the reactor body 1. The hot fluid enters the heating device and is heated again before entering the reactor body 1 to continuously heat the reactants therein. The heat exchange component 4 introduces the hot fluid into the rotating shaft 21 and the U-shaped stirring tube 22 to continuously exchange heat with the reactants in the reactor body 1. The rotating shaft 21 continuously exchanges heat with the center of the reactants, and the U-shaped stirring tube 22 continuously stirs and rotates, and will contact the reactants at different levels, performing multi-level heat exchange on the reactants, ensuring that the heat exchange effects of each level of the reactants are roughly consistent, thereby improving the heat exchange efficiency and ensuring the reaction quality of the reactants. Good reaction products are collected from the discharge pipe 14.
