Description
Technical Field
[0001] This utility model belongs to the field of chemical equipment technology, and in particular relates to a pressure vessel for physical and chemical reactions of metal catalysts. Background Technology
[0002] According to the published patent CN208141839U, a reactor pressure vessel for a metal coolant fast reactor includes a bottom head, a straight section, a flat top cover, and a central tube. The straight section is positioned above the bottom head and fixed to its upper opening. The flat top cover is positioned above the straight section, forming a sealed structure. This design solves the problems of existing reactors where the chain reaction cannot be maintained after fuel assemblies reach a certain burnup level and become spent fuel, as well as the issues of radioactive leakage due to the need to open the cover for refueling and the long refueling cycle. However, it still has the following shortcomings:
[0003] The above-mentioned equipment simply controls the feeding and discharging of materials to prevent leakage during material replacement. However, during the reaction of metal with the catalyst, some metal may be exposed outside the catalyst and cannot fully contact and mix with the catalyst solution, which will lead to a decrease in the reaction rate of the device. Therefore, we propose a pressure vessel for the physicochemical reaction of metal catalysts. Utility Model Content
[0004] The purpose of this invention is to provide a pressure vessel for the physicochemical reaction of metal catalysts. Through the stirring mechanism and the screening mechanism, it solves the problem that existing equipment only controls the simple feeding and discharging of materials to prevent leakage during material replacement. However, during the reaction of metal with the catalyst, some metal may be exposed outside the catalyst and cannot fully contact and mix with the catalyst solution, thus reducing the reaction rate of the device.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model is a pressure vessel for physical and chemical reactions of metal catalysts, including a reaction vessel body, a plurality of injection ports are fixedly connected to the top outer wall of the reaction vessel body, a protective cover is fixedly connected to the top outer wall of the reaction vessel body near the injection ports, a discharge pipe is fixedly connected to the bottom outer wall of the reaction vessel body, and a stirring mechanism is provided on the outer wall of the reaction vessel body.
[0007] The stirring mechanism includes a motor, the outer wall of which is fixedly connected to the outer wall of the reaction vessel body. The bottom output end of the motor is fixedly connected to a drive shaft via a coupling. The outer wall of the drive shaft is rotatably connected to the inner wall of the protective cover. A rotating bushing is rotatably connected to the inner wall of the reaction vessel body. A rotating shaft is rotatably connected to the inner wall of the rotating bushing. The outer wall of the rotating shaft is rotatably connected to the inner wall of the protective cover. Both the outer wall of the rotating shaft and the outer wall of the rotating bushing are fixedly connected to bevel gears.
[0008] Furthermore, a second bevel gear is fixedly connected to the outer wall of one end of the drive shaft near the bevel gear, and the outer walls of several bevel gears mesh with the outer wall of the second bevel gear. A stirring rod is fixedly connected to the bottom outer wall of the rotating shaft, and several scrapers are slidably connected to the inner wall of the rotating shaft sleeve.
[0009] Furthermore, a number of telescopic rods are fixedly connected to the inner wall of the rotating bushing, and a number of springs are fixedly connected to the inner wall of the rotating bushing near one end of the telescopic rods. The outer walls of the telescopic rods and the outer walls of the springs are both fixedly connected to the outer wall of the scraper. A screening mechanism is provided on the inner wall of the reaction vessel body.
[0010] Furthermore, the screening mechanism includes an arc-shaped sieve plate, the outer wall of which is slidably connected to the inner wall of the reaction vessel body.
[0011] Furthermore, an arc-shaped sieve plate two is rotatably connected to the outer wall of the arc-shaped sieve plate one, the outer wall of the arc-shaped sieve plate two is slidably connected to the inner wall of the reaction vessel body, and a fixing block is fixedly connected to the outer wall of the arc-shaped sieve plate two.
[0012] Furthermore, a second fixing block is fixedly connected to the outer wall of the arc-shaped sieve plate near the fixing block, and a fixing rod is fixedly connected to both the outer wall of the second fixing block and the outer wall of the fixing block.
[0013] Furthermore, a number of limiting plates are fixedly connected to the outer wall of the main body of the reaction vessel near the second fixing block, and a sliding plate is slidably connected to the outer wall of the limiting plate.

The outer wall of the electric telescopic rod is fixedly connected to the outer wall of the slide plate.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model incorporates a stirring rod on a rotating shaft. When the equipment is needed, metal and catalyst are injected into the main body of the reaction tank through different inlets. Subsequently, the motor is started, and the rotation of the motor drives the transmission shaft to rotate, causing the second bevel gear to rotate. The rotation of the second bevel gear drives the upper and lower bevel gears to rotate simultaneously in opposite directions. The rotation of the bevel gears drives the rotating shaft and the rotating shaft sleeve to rotate in opposite directions, thereby achieving the goal of agitating the material mixture during the reaction of metal and catalyst, ensuring that the metal fully contacts and reacts with the catalyst, and improving the reaction efficiency.
[0017] 2. This utility model incorporates an arc-shaped groove on the slide plate. During the reaction process, the solid material precipitated from the reaction between the metal and the catalyst remains on the first and second arc-shaped sieve plates, serving a screening function. After the reaction is complete, the mixture can be discharged by turning the valve on the discharge pipe. When it is necessary to remove the fixed material, the electric telescopic rod is activated. The extension of the electric telescopic rod will cause the slide plate to slide away from the electric telescopic rod on the limit plate, thus achieving the screening process during the reaction between the metal and the catalyst, separating the solid material and solution produced by the reaction for subsequent use by the user.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-5 As shown, this utility model is a pressure vessel for physical and chemical reactions of metal catalysts, including a reaction vessel body 1. Several injection ports 101 are fixedly connected to the top outer wall of the reaction vessel body 1. A protective cover 102 is fixedly connected to the top outer wall of the reaction vessel body 1 near the injection ports 101. A discharge pipe 103 is fixedly connected to the bottom outer wall of the reaction vessel body 1. A stirring mechanism 2 is provided on the outer wall of the reaction vessel body 1. Since the discharge pipe 103 has a valve, it is convenient for the user to freely control the discharge rate.
[0029] The stirring mechanism 2 includes a motor 201, the outer wall of which is fixedly connected to the outer wall of the reaction vessel body 1. A drive shaft 202 is fixedly connected to the bottom output end of the motor 201 via a coupling. The outer wall of the drive shaft 202 is rotatably connected to the inner wall of the protective cover 102. A rotating bushing 204 is rotatably connected to the inner wall of the reaction vessel body 1. When the rotating bushing 204 rotates, it can drive multiple scrapers 208 to rotate simultaneously, thereby scraping off the material adhering to the inner wall of the reaction vessel body 1 and improving the efficiency of material removal. To improve material utilization, a rotating shaft 203 is rotatably connected to the inner wall of the rotating sleeve 204. The outer wall of the rotating shaft 203 is rotatably connected to the inner wall of the protective cover 102. Both the outer wall of the rotating shaft 203 and the outer wall of the rotating sleeve 204 are fixedly connected to bevel gears 205. The bevel gears 205 can drive the rotating shaft 203 and the rotating sleeve 204. When the bevel gears 206 rotate, they can drive the bevel gears 205 to rotate, which in turn can drive the rotating shaft 203 and the rotating sleeve 204 to rotate respectively.
[0030] A second bevel gear 206 is fixedly connected to the outer wall of the drive shaft 202 near the bevel gear 205. The outer walls of several bevel gears 205 mesh with the outer walls of the second bevel gear 206. A stirring rod 207 is fixedly connected to the bottom outer wall of the rotating shaft 203. When the stirring rod 207 rotates, it can make full contact between the metal and the catalyst in the reaction vessel body 1, thereby increasing the reaction rate. Several scrapers 208 are slidably connected to the inner wall of the rotating shaft sleeve 204. Several telescopic rods 209 are fixedly connected to the inner wall of the rotating shaft sleeve 204. Several springs 210 are fixedly connected to the inner wall of the rotating shaft sleeve 204 near the telescopic rods 209. The springs 210 will... Through its own elastic force, it always presses against the scraper 208 to keep it close to the inner wall of the reaction vessel body 1. The outer walls of the telescopic rod 209 and the spring 210 are both fixedly connected to the outer wall of the scraper 208. The inner wall of the reaction vessel body 1 is provided with a screening mechanism 3, which includes an arc-shaped screen plate 301. The outer wall of the arc-shaped screen plate 301 is slidably connected to the inner wall of the reaction vessel body 1. Through the arc-shaped screen plate 301, the material in the reaction vessel body 1 can be screened. Because of its large volume, the metal cannot enter below the arc-shaped screen plate 301, and the solid material generated by the reaction also cannot enter below the arc-shaped screen plate 301.
[0031] An arc-shaped sieve plate 302 is rotatably connected to the outer wall of arc-shaped sieve plate 1. The outer wall of arc-shaped sieve plate 302 is slidably connected to the inner wall of the reaction vessel body 1. A fixing block 303 is fixedly connected to the outer wall of arc-shaped sieve plate 302. A fixing block 304 is fixedly connected to the outer wall of arc-shaped sieve plate 1 near the fixing block 303. The fixing block 304 can fix the position of the fixing rod 305 to prevent the fixing rod 305 from falling off. Fixing rods 305 are fixedly connected to both the outer wall of fixing block 303 and the outer wall of fixing block 304. Several fixing rods 305 are fixedly connected to the outer wall of the reaction vessel body 1 near the fixing block 304. The limiting plate 308 has a sliding plate 306 slidably connected to its outer wall. When the sliding plate 306 moves, it drives the fixed rod 305 to move through the arc groove 307, which in turn drives the fixed block 303 and the second fixed block 304 to move. Several arc grooves 307 are opened on the inner wall of the end of the sliding plate 306 near the fixed rod 305. An electric telescopic rod 309 is fixedly connected to the outer wall of the reaction tank body 1 near the sliding plate 306. The outer wall of the electric telescopic rod 309 is fixedly connected to the outer wall of the sliding plate 306. The limiting plate 308 can limit the movement trajectory of the sliding plate 306 and prevent the sliding plate 306 from falling.
[0032] One specific application of this embodiment is:
[0033] When the equipment is needed, the metal and catalyst are injected into the reactor body 1 through different inlets 101. Then, the motor 201 is started. The rotation of the motor 201 drives the transmission shaft 202 to rotate, causing the second bevel gear 206 to rotate. The rotation of the second bevel gear 206 drives the upper and lower bevel gears 205 to rotate simultaneously in opposite directions. The rotation of the bevel gears 205 drives the rotating shaft 203 and the rotating bushing 204 to rotate in opposite directions. The rotation of the rotating shaft 203 drives the stirring rod 207 to rotate, stirring the metal and catalyst. The rotation of the rotating bushing 204 drives the scraper 208 to rotate, scraping off the material adhering to the inner wall of the reactor body 1. The spring 210, through its elastic force, constantly presses the scraper 208 to keep it pressed tightly against the inner wall of the reactor body 1. During the reaction, the metal and catalyst... The solid material precipitated from the reaction will remain on the first arc-shaped sieve plate 301 and the second arc-shaped sieve plate 302, serving as a sieving function. After the reaction is completed, the mixture can be discharged by turning the valve on the discharge pipe 103. When it is necessary to remove the fixed material, the electric telescopic rod 309 is activated. The extension of the electric telescopic rod 309 will cause the slide plate 306 to slide away from the electric telescopic rod 309 on the limiting plate 308. The movement of the slide plate 306 will cause the upper and lower fixed rods 305 to slide simultaneously in the arc-shaped groove 307. The upward movement of the upper fixed rod 305 will cause the fixed block 303 303 to rotate, thereby causing the second arc-shaped sieve plate 302 to flip downward. When the lower fixed rod 305 moves downward, it will cause the fixed block 304 to rotate, thereby causing the first arc-shaped sieve plate 301 to also flip downward. At this time, the fixed material will fall and be discharged from the discharge pipe 103.
