Description

Technical Field

[0001] The invention relates to the field of reaction kettles, and more particularly to an explosion-proof high-pressure reaction kettle. Background Art

[0002] Explosion-proof design is an important feature of explosion-proof high-pressure reactors. Since most of the materials in high-pressure reactors are hazardous chemicals, improper operation or equipment failure may cause safety accidents such as explosions and leaks. Therefore, explosion-proof high-pressure reactors use explosion-proof structural designs and materials to prevent explosion accidents in high-pressure and high-temperature environments.

[0003] The size of the container directly affects the frequency of collisions between reactant molecules. In smaller containers, the distance between reactant molecules is closer and the collision frequency is higher, which may speed up the reaction rate. Therefore, for reactions that need to be carried out quickly, small containers may be more suitable. On the contrary, in some cases, large containers can provide a more uniform reaction environment, reduce concentration gradients, and help avoid local overheating or supercooling, thereby ensuring a smooth reaction. Therefore, containers of different sizes are often required for reactions when in use. However, traditional reactors cannot change their own volumes and can only be replaced by replacing the reactor to achieve different volumes.

[0004] In view of this, in view of the above-mentioned shortcomings, the present invention produces an explosion-proof high-pressure reactor. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The device is provided with a variable volume component. When the volume needs to be reduced, it only needs to be pushed to the bottom of the high-pressure tank. At this time, the variable volume component is acted upon by air pressure and water pressure, so that the variable volume component is fixed at the bottom of the high-pressure tank. At this time, all the solution is located inside the reaction chamber.

[0021] 3. The device is provided with an upper sealed shell and a lower sealed shell. When certain reagents are added, the reactants react quickly, causing a sudden increase in the pressure inside the high-pressure tank. At this time, the tank is easily ruptured due to pressure imbalance. The upper sealed shell and the lower sealed shell can slide, which not only has different reaction spaces, but can also be compressed when the pressure suddenly rises, providing additional explosion-proof protection for the device and improving safety.

[0022] 4. The device is provided with a collecting box and a first arc-shaped plate, so that it can collect impurities and remove impurities in real time, thereby improving the continuous working ability of the device and preventing the accumulation of impurities from causing reaction stagnation.

[0023] 5. This device is equipped with a pressure-limiting component. When the gas is sprayed, the chemical reagents entrained in the gas will be absorbed by the PTFE sponge. The PTFE (polytetrafluoroethylene) sponge has unique properties and high chemical stability. It is not easy to be corroded or react, which prevents the chemical reagents from escaping and causing harm. In addition, as the gas is sprayed, the PTFE sponge can be continuously squeezed to reflux the liquid inside it, which will not cause waste of reagents. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0036] See also Figures 1 to 9, an explosion-proof high-pressure reactor, comprising a high-pressure tank body 1, a detachable explosion-proof cover body 11 is installed on the upper end of the high-pressure tank body 1, a pressure-limiting component 4 for explosion-proof is installed on the explosion-proof cover body 11, a variable volume component 2 and a filtering and stirring component 3 are provided on the internal sliding card of the high-pressure tank body 1, the filtering and stirring component 3 is located above the variable volume component 2, the variable volume component 2 can change the capacity inside the high-pressure tank body 1, the filtering and stirring component 3 can drive the variable volume component 2 to work and stir and filter the reaction solution inside the high-pressure tank body 1, a feed pipe 12, an air intake pipe 13, and an exhaust pipe 14 are fixedly connected and installed on the explosion-proof cover body 11, a discharge pipe 17 is fixedly connected and installed on the lower end of the outer surface of the high-pressure tank body 1, the air intake pipe 13, the exhaust pipe 14, the lifting cylinder 16, and the discharge pipe 17 are all installed with electric control valves, and a plurality of evenly distributed lifting cylinders 16 are fixedly installed on the upper surface of the explosion-proof cover body 11;

[0037] During actual use, the raw materials to be reacted are first added to the interior of the high-pressure tank body 1 through the feed pipe 12. The raw materials will first fall on the filtering and stirring component 3 and then react. Steam is introduced into the interior of the high-pressure tank body 1 through the air inlet pipe 13. The steam can be used to heat the reactants and pressurize the interior of the high-pressure tank body 1. The exhaust pipe 14 is used to extract the gas inside the high-pressure tank body 1. When the steam is filled so that the interior of the high-pressure tank body 1 has a certain pressure, the air inlet pipe 13 and the exhaust pipe 14 are closed so that the internal pressure of the high-pressure tank body 1 is in a high pressure state to provide the pressure required for the reaction. At this time, the lifting cylinder 16 is controlled to work to drive the filtering and stirring component 3 and the variable volume component 2 to work synchronously. When the filtering and stirring component 3 and the variable volume component 2 work synchronously, the solution inside the high-pressure tank body 1 can be stirred, and the variable volume component 2 can also be controlled to separate from the filtering and stirring component 3. The separated variable volume component 2 can reduce the capacity of the reaction inside the high-pressure tank body 1, and with the reciprocating movement of the filtering and stirring component 3, the variable volume component 2 can be driven to stir and filter the solution, and the solid precipitate produced by the reaction can be filtered.

[0038] The variable capacity component 2 includes an upper sealed shell 21, a lower sealed shell 22 is slidably clamped at the inner lower end of the upper sealed shell 21, a second sealing member 221 is integrally formed at the inner center of the lower sealed shell 22, a first flow component 23 is fixedly installed at the middle of the upper surface of the upper sealed shell 21, a first sealing member 211 is integrally formed at the inner lower surface of the upper sealed shell 21, the first sealing member 211 is slidably sleeved on the outside of the second sealing member 221, a plurality of uniformly distributed first springs 24 are fixedly connected between the upper sealed shell 21 and the lower sealed shell 22, the filtering and stirring component 3 includes a filter plate 31, a second flow component 32 is installed at the middle of the upper surface of the filter plate 31, and the first sealing member 211 and the lower sealed shell 22 form a reaction chamber 25 The reaction chamber 25 is connected with the first flow component 23 and the second flow component 32 in sequence. A plurality of evenly distributed first channels 101 are provided on the inner lower surface of the high-pressure tank body 1. A central groove 103 is provided in the middle of the inner lower surface of the high-pressure tank body 1. A plurality of connecting pipes 102 corresponding to the first channels 101 are fixedly installed on the inner lower surface of the high-pressure tank body 1. The two ends of the first channel 101 are respectively connected with the connecting pipe 102 and the central groove 103. A plurality of through holes 222 corresponding to the connecting pipe 102 are provided on the lower surface of the lower sealing shell 22. A piston 104 is provided inside the central groove 103. A plurality of evenly distributed telescopic rods 105 are fixedly installed on the lower surface of the piston 104. The telescopic rods 105 are buried inside the central groove 103.

[0039] When the filtering and stirring component 3 drives the variable-capacity component 2 to descend, the filtering and stirring component 3 pushes the variable-capacity component 2 to descend. When the upper sealed shell 21 contacts the reaction solution, the upper sealed shell 21 and the lower sealed shell 22 are in the maximum position. At this time, the through hole 222 is easily blocked, resulting in the gas inside the upper sealed shell 21 and the lower sealed shell 22 being unable to escape. At this time, the upper sealed shell 21 and the lower sealed shell 22 maintain the maximum state and will descend with the filtering and stirring component 3. At this time, because the reaction solution is squeezed, it will enter the interior of the reaction chamber 25. When it is easy to enter the interior of the reaction chamber 25, the gas inside the reaction chamber 25 will flow into the top of the filtering and stirring component 3 through the first flow component 23 and the second flow component 32. As the filtering and stirring component 3 continues to descend, the solution will also flow to the top of the filtering and stirring component 3 through the first flow component 23 and the second flow component 32. When the filtering and stirring component 3 drives the variable-capacity component 2 to continue When it continues to descend, the connecting pipe 102 enters the interior of the through hole 222. At this time, the upper sealing shell 21 is against the inner bottom end of the high-pressure tank body 1. As the filtering and stirring component 3 continues to descend, the upper sealing shell 21 slides along the lower sealing shell 22 so that the first spring 24 is compressed. At this time, the piston 104 will slide and enter the interior of the second sealing component 221. When the upper sealing shell 21 continues to descend, the gas inside the upper sealing shell 21 and the lower sealing shell 22 will enter the interior of the central groove 103 through the connecting pipe 102 and the first channel 101. At this time, because the piston 104 and the second sealing component 221 are sealed and slidable, when the gas enters the interior of the central groove 103, the gas inside the central groove 103 gradually increases. At this time, the piston 104 is pushed up. When the piston 104 rises, it will push the solution inside the reaction chamber 25 through the first flow component 23 and the second flow component 32 to the top of the filtering and stirring component 3.

[0040] When the filter stirring component 3 drives the variable volume component 2 to rise, the solution above the filter stirring component 3 will pass through the second flow component 32 and the first flow component 23 and return to the bottom of the variable volume component 2, so as to achieve the purpose of stirring. When the upper sealed shell 21 is driven to rise by the filter stirring component 3, under the action of the first spring 24, the lower sealed shell 22 will be pushed gradually away from the upper sealed shell 21, and negative pressure will be generated inside the upper sealed shell 21 and the lower sealed shell 22. Under the action of the negative pressure, the gas inside the central groove 103 will return to the interior of the upper sealed shell 21 along the first channel 101 and the connecting pipe 102, and the piston 104 will descend. When the piston 104 descends, the interior of the reaction chamber 25 will be produced. Negative pressure is generated, which can drive the solution to pass through the second flow component 32 and the first flow component 23 and return to the interior of the reaction chamber 25. Because the liquid has a certain resistance when it flows in the opposite direction, and the gas will also generate resistance when passing through the first channel 101 and the connecting pipe 102, the lower sealed shell 22 will always be in contact with the lower surface of the high-pressure tank body 1. When all the gas in the central groove 103 returns to the upper sealed shell 21 and the lower sealed shell 22, it means that the solution above the filtering and stirring component 3 will return to the interior of the reaction chamber 25. At this time, when the filtering and stirring component 3 continues to rise, it will drive the variable-volume component 2 to rise together, and the gas above the filtering and stirring component 3 will also return to the bottom of the variable-volume component 2 as it moves.

[0041] The device is provided with a variable volume component 2. When the volume needs to be reduced, it only needs to push the variable volume component 2 to the inner bottom end of the high-pressure tank body 1. At this time, the variable volume component 2 is acted upon by air pressure and water pressure, so that the variable volume component 2 is fixed at the inner bottom end of the high-pressure tank body 1. At this time, all the solution is located inside the reaction chamber 25. Because the diameter of the reaction chamber 25 is much smaller than the inner diameter of the high-pressure tank body 1, the space for solution reaction can be reduced, so that the reactor can have different reaction spaces to adapt to different reaction requirements.

[0042] The first circulation component 23 includes a first sealing ring 231, and the upper end of the first sealing ring 231 is slidably clamped with a first sealing cover plate 232. The lower end of the first sealing ring 231 is provided with a plurality of evenly distributed leakage grooves 233, and a rotating plate 234 is rotatably installed inside the leakage groove 233. The second circulation component 32 includes a second sealing ring 321, and the second sealing ring 321 is fixedly installed on the filter plate 31. The driving end of the lifting cylinder 16 passes through the explosion-proof cover body 11 and is fixedly installed on the upper surface of the second sealing ring 321. The upper end of the second sealing ring 321 is slidably clamped with a second sealing cover 322, and the first sealing ring 231 is located inside the second sealing ring 321.

[0043] When the filtering and stirring component 3 is separated from the variable-capacity component 2, the variable-capacity component 2 is located at the bottom end of the high-pressure tank body 1. At this time, the lifting cylinder 16 is controlled to work and drive the filtering and stirring component 3 to move back and forth. When the filtering and stirring component 3 moves and squeezes the upper sealing shell 21, the upper sealing shell 21 descends, and the solution inside the reaction chamber 25 pushes the first sealing cover plate 232 to rise. At this time, the first flow component 23 is in an open state, and the solution enters the second sealing ring 321. As the filtering and stirring component 3 continues to descend, the solution inside the reaction chamber 25 pushes the second sealing cover 322 to open the second sealing cover 322. At this time, the solution passes through the first flow component 23 and the second flow component 32 to enter the top of the filtering and stirring component 3. When the filtering and stirring component 3 rises, because the filtering and stirring component 3 is separated from the variable volume component 2, so when the filtering and stirring component 3 rises, the liquid will push the second sealing cover 322 from above the second sealing cover 322, and the second sealing cover 322 will block the second sealing ring 321. At this time, the solution will pass through the filter holes on the filter plate 31, and the solution filtered by the filter holes will enter between the filter plate 31 and the upper sealing shell 21. At this time, because the upper sealing shell 21 is pushed up by the first spring 24, and the inside of the reaction chamber 25 generates negative pressure under the action of the piston 104, the rotating plate 234 will rotate to open the leakage groove 233. At this time, the solution will pass through the leakage groove 233 and enter the inside of the reaction chamber 25. When the solution reacts inside the reaction chamber 25, the gas generated by the reaction will push open the first sealing cover plate 232 and the second sealing cover 322 and enter the top of the filtering and stirring component 3.

[0044] By setting up a filtering and stirring component 3, the present device can not only be used to change the volume inside the high-pressure tank body 1 when the filtering and stirring component 3 moves back and forth, but also realize a stirring effect. Stirring can be realized by controlling the connection or disconnection of the filtering and stirring component 3 and the variable volume component 2. During stirring, solid precipitation can also be filtered on the upper surface of the filter plate 31 to prevent the precipitation from affecting the reaction.

[0045] When the user operates improperly, such as adding the wrong reagent, the reactants react quickly, causing a sudden increase in the pressure inside the high-pressure tank 1. At this time, the tank is easily ruptured due to pressure imbalance. The upper sealed shell 21 and the lower sealed shell 22 can slide, which not only has different reaction spaces, but can also be compressed when the pressure suddenly rises, providing additional explosion-proof protection for the device and improving safety.

[0046] A plurality of evenly distributed motors 34 are fixedly mounted on the upper surface of the second sealing ring 321, a rotating block 341 is fixedly mounted on the driving end of the motor 34, a connecting plate 342 is integrally formed on one side of the rotating block 341, the connecting plate 342 passes through the side wall of the second sealing ring 321, and a connecting groove 235 for use with the connecting plate 342 is provided on the outer ring of the first sealing ring 231.

[0047] When it is necessary to combine the filtering and stirring component 3 and the variable capacity component 2, it is only necessary to control the motor 34 to work. The motor 34 drives the rotating block 341 and the connecting plate 342 to rotate. When the connecting plate 342 rotates and enters the interior of the connecting groove 235, if the lifting cylinder 16 is controlled to drive the filtering and stirring component 3 to rise, the connecting plate 342 will slide along the interior of the connecting groove 235 for a distance and then clamp the first sealing ring 231. When the connecting plate 342 rises for a distance, the filter plate 31 also rises. At this time, the filter plate 31 is staggered with the leakage groove 233. At this time, the solution can pass through the filter plate 31 and enter the interior of the leakage groove 233. When the filtering and stirring component 3 descends, the connecting plate 342 will descend along the leakage groove 233, and the filter plate 31 is fitted with the upper surface of the upper sealing shell 21. At this time, the leakage groove 233 is in a closed state, and the liquid cannot pass through the leakage groove 233 and can only flow out through the position of the first sealing ring 231.

[0048] A rotating ring 33 is rotatably sleeved on the outer lower end of the second sealing ring 321, and a plurality of evenly distributed first arc plates 331 are fixedly installed on the outer ring of the rotating ring 33, and a second arc plate 332 is rotatably installed on the end of the first arc plate 331 away from the rotating ring 33, and the first arc plate 331 and the second arc plate 332 are both fitted on the upper surface of the filter plate 31, and a rotating wheel 333 is fixedly installed on the upper surface of the end of the first arc plate 331 away from the rotating ring 33, and the rotating wheel 333 is inclined to fit the inner wall of the high-pressure tank body 1, and a plurality of evenly distributed collecting boxes 15 are fixedly installed on the upper end of the high-pressure tank body 1, and the collecting boxes 15 are connected to the interior of the high-pressure tank body 1.

[0049] When the filter plate 31 slides back and forth along the inside of the high-pressure tank body 1, the rotating wheel 333 will slide along the surface of the high-pressure tank body 1. Because the rotating wheel 333 is designed to be inclined, when the filter stirring component 3 moves, the rotating wheel 333 will move spirally along the inner wall of the high-pressure tank body 1, that is, the rotating ring 33 will drive the first curved plate 331 and the second curved plate 332 to rotate. When the first curved plate 331 rotates, it will scrape and clean the surface of the filter plate 31. When the filter stirring component 3 is not in contact with the collection box 15, the filter plate 31 will be removed. When they are coplanar, the impurities will be scraped to the outer periphery of the upper surface of the filter plate 31 by the first curved plate 331 and the second curved plate 332. A torsion spring is installed between the second curved plate 332 and the first curved plate 331. When the filtering stirring component 3 moves to be coplanar with the collecting box 15, as the rotating ring 33 rotates, the second curved plate 332 will push the gathered impurities into the interior of the collecting box 15, so as to collect the impurities and remove them in real time, thereby improving the continuous working ability of the device and preventing the accumulation of impurities from causing reaction stagnation.

[0050] The pressure limiting component 4 includes a pressure relief pipe 41, which is connected to the interior of the high-pressure tank body 1. A first pipe 42 is fixedly installed at one end of the pressure relief pipe 41 away from the explosion-proof cover body 11. A plurality of evenly distributed second pipes 421 are integrally formed at one end of the first pipe 42 away from the pressure relief pipe 41. A PTFE sponge 43 is fixedly installed at one end of the first pipe 42 close to the pressure relief pipe 41. A first pressure plate 44 is provided on the side of the PTFE sponge 43 away from the pressure relief pipe 41. The first pressure plate 44 is slidably clamped in the interior of the first pipe 42. A threaded sleeve 45 is rotatably installed in the middle of the second pipe 421. A threaded rod 46 is clamped at one end of the threaded sleeve 45 close to the first pipe 42 through threaded cooperation. A second pressure plate 47 is fixedly installed at one end of the threaded rod 46 away from the threaded sleeve 45. The second pressure plate 47 is slidably clamped in the interior of the second pipe 421. A second spring 48 is fixedly connected between the second pressure plate 47 and the first pressure plate 44.

[0051] When the air pressure inside the high-pressure tank body 1 is too high, the gas will pass through the PTFE sponge 43 and push the first pressure plate 44. The first pressure plate 44 is pushed into the second pipe 421. Because the inner diameter of the second pipe 421 is larger than that of the first pipe 42, when the first pressure plate 44 enters the second pipe 421, the gas will quickly pass through the second pipe 421 and be output to the outside of the device. Because the gas flows away quickly, the pressure inside the first pipe 42 is reduced. At this time, under the action of the second spring 48, the first pressure plate 44 will re-enter the PTFE sponge 43 until it is pushed next time. When the first pressure plate 44 repeatedly enters the first pipe 42, it will squeeze the PTFE sponge 43, squeeze the solution inside the PTFE sponge 43, and return it to the inside of the high-pressure tank body 1 along the pressure relief pipe 41. When in use, the thrust of the second spring 48 on the first pressure plate 44 can be adjusted by rotating the threaded sleeve 45 to adjust the pressure threshold of the device.

[0052] When the pressure of the device is too high, a large amount of gas will be sprayed out from the pressure relief position. Because the speed of the gas spray is too fast, some chemical reagents will be sprayed out, which may not only cause environmental pollution, but also may cause harm to the staff if the solution is corrosive. Therefore, the device is provided with a pressure limiting component 4. When the gas is sprayed, the chemical reagents entrained by the gas will be absorbed by the PTFE sponge 43. The PTFE sponge 43 has unique properties and high chemical stability, is not easily corroded or reacted, and prevents the chemical reagents from escaping and causing harm. In addition, as the gas is sprayed, the PTFE sponge 43 can be continuously squeezed to cause the liquid inside to flow back, and no reagent waste will be caused.

[0053] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
