[0002] HIGH-PRESSURE REACTOR WITH ADJUSTABLE BAFFLES
[0003] FIELD OF THE DISCLOSURE
[0004] The present invention relates to the field of reactor technology, specifically to a high-pressure reactor with adjustable baffles.
[0005] BACKGROUND
[0006] High-pressure reactors are core and heavy-duty equipment in the high-pressure leaching process of lateritic nickel ore, primarily used for the high-pressure leaching of nickel and cobalt The interior of a high-pressure reactor is typically divided into multiple compartments, each equipped with a mechanical stirring device to facilitate the thorough reaction between the ore pulp and acid. Adjacent compartments are separated by baffles, which enhance the shearing effect of the fluid during stirring. In production, the reactor sequentially passes through each compartment. To ensure that the reactants can pass through the baffles, both the upper and lower ends of the baffles are equipped with openings.
[0007] Although the openings at the upper and lower ends of the baffles facilitate the passage of reactants, they also weaken the baffles' blocking effect on the reactants, affecting the shearing action of the stirring process on the fluid. In design, if the openings on the baffles are large, it will affect the blocking effect of the baffles on the fluid and the high-pressure leaching efficiency. If the openings are small, it will slow down the rate at which the material passes through the baffles, affecting the production efficiency. Therefore, how to improve the baffles' blocking effect on the material, enhance the stirring effect, and increase the high-pressure leaching efficiency without affecting production efficiency is an urgent technical problem that needs to be solved. SUMMARY
[0008] The objective of the invention is to overcome the aforementioned technical deficiencies and propose a high-pressure reactor with adjustable baffles. This invention aims to improve the baffles’ blocking effect on the material, enhance the stirring effect, and increase the high-pressure leaching efficiency without affecting production efficiency.
[0009] To achieve the above technical objectives, the present invention adopts the following technical solution:
[0010] The invention provides a high-pressure reactor with adjustable baffles, which includes:
[0011] A reactor body;
[0012] A number of baffle components, arranged equidistantly along the length of the reactor body to divide the interior cavity of the reactor body into several isolated chambers. Each baffle component includes a fixed baffle, a movable baffle, and a lift drive mechanism. The fixed baffle is fixed in the reactor body and is uniformly equipped with several first through-slots. The movable baffle is fitted to the fixed baffle and is uniformly equipped with several second through-slots that correspond with the first through-slots. The lifting drive mechanism is connected to the movable baffle and is used to drive the movement of the movable baffle to align or stagger the first through-slots with the second through-slots; and
[0013] A number of stirring components, each respectively set within the isolated chambers.
[0014] In some embodiments, the baffle component also includes a lower limit plate and a lower limit rod. The lower limit plate is fixed at the lower end of the movable baffle with a lower limit hole. The lower limit rod is fixed at one end to the inner bottom wall of the reactor body and is slidably inserted into the lower limit hole.
[0015] In some embodiments, the baffle component also includes an upper limit plate and an upper limit rod. The upper limit plate is fixed at the upper end of the movable baffle with an upper limit hole. The upper limit rod is fixed at one end to the inner top wall of the reactor body and is slidably inserted into the upper limit hole.
[0016] In some embodiments, the lifting drive mechanism is connected to the upper limit plate and is used to drive the upper limit plate to move up and down.
[0017] In some embodiments, the top surface of the reactor body is equipped with a through-hole.
[0018] The lifting drive mechanism includes a lifting rod, a lower mounting plate, an upper mounting plate, a column, a sleeve, a lead screw, a nut, and a rotary drive mechanism. The lifting rod is slidably inserted into the through-hole with its lower end fixedly connected to the upper limit plate. The lower mounting plate is fixed to the upper top surface of the reactor body. The column is fixed at both ends to the lower and upper mounting plates, respectively. The sleeve is slidably fitted onto the column. The lead screw is vertically mounted with both ends rotatably connected to the lower and upper mounting plates. The nut is threaded onto the lead screw and is fixedly connected to the lifting rod and the sleeve. The rotary drive mechanism is connected to the lead screw and is used to drive the rotation of the lead screw.
[0019] In some embodiments, the nut is fixedly connected to the lifting rod via a first connecting rod.
[0020] In some embodiments, the nut is fixedly connected to the sleeve via a second connecting rod.
[0021] In some embodiments, the rotary drive mechanism includes a rotary drive motor, a driving gear, and a driven gear. The housing of the rotary drive motor is fixed to the reactor body, with the driving gear fixed coaxially to the output shaft of the rotary drive motor. The driven gear is fixed coaxially to the lead screw and meshes with the driving gear.
[0022] In some embodiments, the stirring component includes a stirring shaft, stirring blades, and a stirring motor. The stirring shaft is rotatably mounted within the reactor body, with the stirring blades fixed to the stirring shaft. The stirring motor is connected to the stirring shaft and is used to drive the rotation of the stirring shaft. In some embodiments, the interior of the reactor body is also fixed with a number of baffle plates.
[0023] Compared to the existing technology, the beneficial effects of the high-pressure reactor with adjustable baffles provided by the present invention are: when in use, the material is introduced from the feed port into the first isolated chamber of the reactor body. At this time, the first through-slots of the fixed baffle are staggered with the second through-slots of the movable baffle. The material is stirred by the stirring component. After stirring for a preset time, the movable baffle is driven by the lifting drive mechanism to align the first through-slots with the second through-slots. The material in the first isolated chamber then enters the second isolated chamber through the first and second through-slots, and is stirred by the stirring component in the second isolated chamber for a preset time. This process is repeated, allowing the material to sequentially enter each isolated chamber for stirring. During stirring, the staggered arrangement of the first and second through-slots enhances the blocking effect on the material, improves the stirring effect, and increases the high-pressure leaching efficiency. After stirring is completed, the movable baffle is driven by the lifting drive mechanism to align the first and second through-slots, allowing the material to quickly enter the next isolated chamber. Thus, the device can improve the blocking effect of the baffles on the material, enhance the stirring effect, and increase the high-pressure leaching efficiency without affecting production efficiency .

[0031] In order to improve the blocking effect of the baffles on the material, enhance the stirring effect, and increase the high- pressure leaching efficiency without affecting production efficiency, the present invention provides a high-pressure reactor with adjustable baffles.
[0032] Refer to Figure 1, which is a structural schematic diagram of a high-pressure reactor with adjustable baffles in an embodiment of the invention. The high-pressure reactor with adjustable baffles includes a reactor body 1, a number of baffle components 2, and a number of stirring components 3.
[0033] The reactor body 1 has a feed port 11 and a discharge opening 12. The lower end of the reactor body 1 also has a slag discharge opening 13, which is equipped with a slag discharge valve.
[0034] The baffle components 2 are arranged equidistantly along the length of the reactor body 1, dividing the interior cavity of the reactor body 1 into several isolated chambers. Each baffle component 2 includes a fixed baffle 21, a movable baffle 22, and a lifting drive mechanism 23. The fixed baffle 21 is secured inside the reactor body 1 and is uniformly equipped with several first through-slots 211. The movable baffle 22 is fitted against the fixed baffle 21 and is uniformly equipped with several second through-slots 221 that correspond with the first through-slots 211. The lifting drive mechanism 23 is connected to the movable baffle 22 and is used to drive the movement of the movable baffle 22 to align or stagger the first through-slots 211 with the second through-slots 221. In this embodiment, the shape of the fixed baffle 21 matches the cross-sectional shape of the interior cavity of the reactor body 1 and can completely isolate the interior cavity of the reactor body 1.
[0035] The baffle components 2 are arranged equidistantly along the length of the reactor body 1, dividing the interior cavity of the reactor body 1 into several isolated chambers. Each baffle component 2 includes a fixed baffle 21, a movable baffle 22, and a lifting drive mechanism 23. The fixed baffle 21 is secured inside the reactor body 1 and is uniformly equipped with several first through-slots 211. The movable baffle 22 is fitted against the fixed baffle 21 and is uniformly equipped with several second through-slots 221 that correspond with the first through-slots 211. The lifting drive mechanism 23 is connected to the movable baffle 22 and is used to drive the movement of the movable baffle 22 to align or stagger the first through-slots 211 with the second through-slots 221. In this embodiment, the shape of the fixed baffle 21 fits with to the cross-sectional shape of the interior cavity of the reactor body 1 and can completely isolate the interior cavity of the reactor body 1.
[0036] Each stirring component 3 is respectively set within each isolated chamber.
[0037] When in use, the material is introduced from the feed port 11 into the first isolated chamber inside the reactor body 1. At this time, the first through-slots 211 of the fixed baffle 21 are staggered with the second through-slots 221 of the movable baffle 22. The material is stirred by the stirring component 3 for a preset duration. After stirring, the movable baffle 22 is driven by the lifting drive mechanism 23 to align the first through- slots 211 with the second through-slots 221. At this point, the material in the first isolated chamber enters the second isolated chamber through the first and second through-slots 211 and 221, respectively. The material is then stirred by the stirring component 3 in the second isolated chamber for a preset duration. This process is repeated, allowing the material to sequentially enter each isolated chamber for stirring. During stirring, the first through-slots 211 are staggered with the second through- slots 221 to enhance the blocking effect on the material, improve the stirring effect, and increase the efficiency of the high- pressure leaching process. After stirring is completed, the movable baffle 22 is driven by the lifting drive mechanism 23 to align the first through-slots 211 with the second through-slots 221, allowing the material to quickly enter the next isolated chamber. Thus, the device can improve the blocking effect of the baffles on the material, enhance the stirring effect, and increase the high-pressure leaching efficiency without affecting production efficiency.

The lower limit plate 24 is fixed at the lower end of the movable baffle 22 and has a lower limit hole. One end of the lower limit rod 25 is fixed to the inner bottom wall of the reactor body 1, and the lower limit rod 25 is slidably inserted into the lower limit hole, allowing for the positioning of the movable baffle 22.
[0039] In another embodiment, as shown in Figure 1 and Figure 3, the baffle component 2 also includes an upper limit plate 26 and an upper limit rod 27. The upper limit plate 26 is fixed at the upper end of the movable baffle 22 and has an upper limit hole. One end of the upper limit rod 27 is fixed to the inner top wall of the reactor body 1, and the upper limit rod 27 is slidably inserted into the upper limit hole, allowing for the positioning of the movable baffle 22.
[0040] In another embodiment, as shown in Figure 1 and Figure 3, the lifting drive mechanism 23 is connected to the upper limit plate 26 and is used to drive the upper limit plate 26 to move up and down . In another embodiment, as shown in Figure 1 and Figure 3, the top surface of the reactor body 1 is equipped with a through-hole. The lifting drive mechanism 23 includes a lifting rod 231, a lower mounting plate 232, an upper mounting plate 233, a column 234, a sleeve 235, a lead screw 236, a nut 237, and a rotary drive mechanism 238. The lifting rod 231 is slidably inserted into the through-hole, with its lower end fixedly connected to the upper limit plate 26. The lower mounting plate 232 is fixed to the upper top surface of the reactor body 1. The column 234 is fixed at both ends to the lower and upper mounting plates 232 and 233, respectively. The sleeve 235 is slidably fitted onto the column 234. The lead screw 236 is vertically mounted, with both ends rotatably connected to the lower and upper mounting plates 232 and 233. The nut 237 is threaded onto the lead screw 236 and is fixedly connected to the lifting rod 231 and the sleeve 235. The rotary drive mechanism 238 is connected to the lead screw 236 and is used to drive the rotation of the lead screw 236. When in use, the rotary drive mechanism 238 drives the lead screw 236 to rotate, which in turn causes the nut 237 to move up and down, lifting or lowering the upper limit plate 26 and the movable baffle 22.
[0041] In one embodiment, as shown in Figure 1 and Figure 3, the nut 237 is fixedly connected to the lifting rod 231 via a first connecting rod 2311.
[0042] In another embodiment, as shown in Figure 1 and Figure 3, the nut 237 is fixedly connected to the sleeve 235 via a second connecting rod 2351.

The housing of the rotary drive motor 2381 is fixed to the reactor body 1, with the driving gear 2382 fixed coaxially to the output shaft of the rotary drive motor 2381. The driven gear 2383 is fixed coaxially to the lead screw 236 and meshes with the driving gear 2382. When in use, the rotary drive motor 2381 drives the driving gear 2382 to rotate, which in turn drives the driven gear 2383 to rotate, causing the lead screw 236 to rotate.
[0044] In one embodiment, as shown in Figure 1 and Figure 3, the stirring component 3 includes a stirring shaft 31, stirring blades 32, and a stirring motor 33. The stirring shaft 31 is rotatably mounted within the reactor body 1, with the stirring blades 32 fixed to the stirring shaft 31. The stirring motor 33 is connected to the stirring shaft 31 and is used to drive the rotation of the stirring shaft 31.
[0045] In one embodiment, as shown in Figure 1, the interior of the reactor body 1 is also fitted with a number of baffle plates 14, which can cause the material to deflect and enhance the stirring effect . For a better understanding of the invention, the technical solution of the invention is described in detail in conjunction with Figures 1 to 3 : When in use, the material is introduced from the feed port 11 into the first isolated chamber inside the reactor body 1. At this time, the first through-slots 211 of the fixed baffle 21 are staggered with the second through-slots 221 of the movable baffle 22. The material is stirred by the stirring component 3 for a preset duration. After stirring, the movable baffle 22 is driven by the lifting drive mechanism 23 to align the first through-slots 211 with the second through-slots 221. At this point, the material in the first isolated chamber enters the second isolated chamber through the first and second through- slots 211 and 221, respectively. The material is then stirred by the stirring component 3 in the second isolated chamber for a preset duration. This process is repeated, allowing the material to sequentially enter each isolated chamber for stirring. During stirring, the first through-slots 211 are staggered with the second through-slots 221 to enhance the blocking effect on the material, improve the stirring effect, and increase the efficiency of the high-pressure leaching process. After stirring is completed, the movable baffle 22 is driven by the lifting drive mechanism 23 to align the first through-slots 211 with the second through- slots 221, allowing the material to quickly enter the next isolated chamber. Thus, the device can improve the blocking effect of the baffles on the material, enhance the stirring effect, and increase the high-pressure leaching efficiency without affecting production efficiency.
