Description

Technical Field

[0001] This invention relates to the field of high-purity catalyst preparation technology, and in particular to an apparatus and method for preparing a high-purity catalyst. Background Technology

[0002] A catalyst is a substance that can accelerate the rate of a chemical reaction without being consumed or altering its chemical properties during the reaction. It makes the reaction easier to occur by lowering the activation energy of the reaction (i.e., the minimum energy required for reactants to be converted into products). Catalysts are widely used in many fields such as chemical engineering, pharmaceuticals, petroleum refining, and environmental protection.

[0003] Catalyst preparation typically involves the following key steps: high-pressure hydrogenation, distillation, filtration, and crystallization. Among these, the equipment used for high-pressure hydrogenation is usually a high-pressure reactor, which consists of a heating system (to heat the temperature inside the reactor), a stirring system (to stir the mixture), a hydrogen supply system (to supply the hydrogen required for the chemical reaction), and a cleaning system (to clean the inside of the reactor).

[0004] However, when the mixture reacts with hydrogen, byproducts that are not completely converted into the target product are produced. These byproducts will deposit at the bottom of the reactor due to their own weight. When these deposits are deposited at the bottom of the reactor and come into contact with the scraper of the cleaning system, they will generate strong physical adhesion. However, when cleaning with existing high-pressure water guns, the energy of the water flow is dispersed when the high-pressure water jet hits the hard deposits due to the impact angle and other issues, thereby reducing the impact force on the deposits. If the cleaning is not thorough, the residual deposits may be mixed into the next mixing, causing contamination, which in turn affects product quality and production efficiency. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides an apparatus and method for preparing a high-purity catalyst.

[0006] The technical solution of the present invention is as follows: A device for preparing a high-purity catalyst, comprising: A reaction vessel, which is provided with a feed inlet and a discharge outlet, and a connecting frame is fixedly connected to the reaction vessel; An electric motor is installed in the reaction vessel, and the drive shaft of the electric motor passes through the reaction vessel and is fixedly connected to a stirrer; A container shell is rotatably connected to the reactor. A cleaning plate is slidably connected to the container shell. A connecting shell is fixed to the container shell. A gas guide shell is fixed to the connecting shell. Several sets of fixed plates are arranged in a ring array. Each set of fixed plates consists of two plates. Two adjacent fixed plates are rotatably connected to a swing shell. The cleaning plate is hidden inside the container shell in a concealed manner. The cleaning plate can only be exposed when cleaning is required. A drive assembly, disposed within the air guide shell, is used to drive the cleaning plate to slide. An air supply assembly, mounted on the connecting frame, is used to supply air into the air guide shell.

[0007] To further explain, the cleaning plate is slidably connected to symmetrically distributed first sliding plates, a first spring is fixedly connected between the first sliding plates and the cleaning plate, and the cleaning plate is fixedly connected to symmetrically distributed limiting plates, which are used to limit the adjacent first sliding plates.

[0008] To further explain, both the container shell and the cleaning plate are provided with several through holes to reduce the resistance when they move relative to the mixed material.

[0009] To further explain, the driving component includes: An elastic liquid bladder is fixedly connected to the air guide shell. An oil-containing shell is fixedly connected to the connecting shell. A sealing element is slidably connected to the oil-containing shell. The sealing element is fixedly connected to the cleaning plate. An L-shaped tube that penetrates the air guide shell and the connecting shell is fixedly connected to the elastic liquid bladder and the oil-containing shell.

[0010] To further explain, the oil-containing shell is slidably connected to the second sliding plate, and the second sliding plate is fixedly connected to the seal with a second spring.

[0011] To further explain, the air supply assembly includes: A driving component is disposed on the connecting frame. A hollow rod is rotatably connected to the telescopic end of the driving component. The hollow rod passes through the drive shaft of the motor and is rotatably connected to it. A first connecting pipe communicating with the air guide shell is fixedly connected to the hollow rod. The hollow rod is fixedly connected to the adjacent side of the elastic liquid bladder. The hollow rod is splinedly connected to the holding shell. A fixed frame is fixedly connected to the connecting frame. The fixed frame is slidably connected to a sliding shell. The sliding shell is rotatably connected to and communicates with a rotating shell. The rotating shell is fixedly connected to and communicates with the hollow rod. A sliding cylinder is slidably connected inside the swing shell. A third spring is provided between the sliding cylinder and the adjacent swing shell. A second communicating pipe is fixedly connected to and communicates with the air guide shell. The sliding cylinder is provided with several communicating holes. The swing shell is provided with several air outlets. When the swing shell is parallel to the horizontal plane, the communicating holes on the sliding cylinder communicate with the air outlets.

[0012] Furthermore, the air supply assembly also includes: Several liquid outlets are located on the side of the swing shell facing away from several air outlets. When the swing shell is perpendicular to the horizontal plane, the connecting hole on the sliding cylinder communicates with the liquid outlet. A nozzle is provided in both the air outlet and the liquid outlet. The symmetrically distributed fixed plates are rotatably connected to a protective shell that is fixed to the swing shell. Each of the symmetrically distributed fixed plates is fixed with a protrusion. The protective shell on the swing shell is slidably connected to a sliding rod that is fixed to the adjacent sliding cylinder. One end of the sliding rod slides along the outside of the protrusion. A connecting assembly is provided on the hollow rod, and the connecting assembly is used to connect the hollow rod and the drive shaft of the motor.

[0013] Further explanation: The connection component includes: A hinge seat is fixed to the upper side of the hollow rod, and a hinge rod corresponding to the swing shell is hinged between the hinge seat and the swing shell. The limiting blocks are arranged in a ring array and fixed to one end of the hollow rod located inside the motor drive shaft. The motor drive shaft is provided with a spline groove, which is used to limit the limiting blocks arranged in the ring array.

[0014] To further explain, the limiting block is composed of equilateral triangular blocks and rectangular blocks, and the equilateral triangular blocks within the limiting block face the spline groove so that all the limiting blocks can be inserted into the spline groove.

[0015] To further explain, the method used in a high-purity catalyst preparation apparatus includes the following steps: Step 1: First, connect the external heating equipment and the external hydrogen supply equipment to the reactor and the sliding shell, respectively; Step 2: After completing the preparation work, put the raw materials, catalysts and additives required for the work into the reaction vessel; Step 3: The motor drives the stirrer to stir the mixture. An external hydrogen delivery device indirectly delivers hydrogen into the sliding cylinder and sprays it out from the nozzle at the outlet. The hydrogen comes into contact with the mixture and produces a chemical reaction. Step 4: After stirring for a period of time, the mixture is converted into the high-purity catalyst required for the operation. Turn off the electrical equipment mentioned in the above steps and discharge the high-purity catalyst from the discharge port at the bottom of the reactor. Step 5: After the high-purity catalyst is discharged, the telescopic part of the drive component extends and drives the hollow rod to move synchronously. The hollow rod drives the lower hinge seat of the elastic liquid bladder and all the limiting blocks to move upward synchronously. Step 6: As the lower side of the elastic fluid bladder moves upward, the pressure inside it increases. Through the transmission of the liquid, the pressure inside the oil-filled shell increases, causing the seal to drive the cleaning plate to slide synchronously. Step 7: During the movement of the hinge seat, all the hinge rods are brought together by all the hinge rods. During the process of all the hinge rods being brought together, the protrusions press against the sliding rods, and the sliding rods drive the sliding cylinder to change the communication state with the swing shell. Step 8: After the above parts have been switched, replace the air inlet in the sliding shell with cleaning fluid, so that the nozzle in the outlet sprays out cleaning fluid to clean the inside of the reactor. Step 9: During the rotation of the hollow rod, the cleaning plate scrapes the bottom of the reactor. Through the third spring on the seal, the cleaning plate scrapes the sediment step by step. The cleaned sediment and waste liquid are discharged from the discharge port on the lower side of the reactor. Step 10: After cleaning the sediment at the bottom of the reactor, the telescopic part of the drive unit drives the parts that move synchronously with the hollow rod to reset one after another.

[0016] Compared with the prior art, the present invention has the following advantages: In order to solve the problem that incompletely converted by-products deposit at the bottom of the reactor during the reaction of the mixture with hydrogen, the present invention adopts a hidden cleaning plate design. When cleaning the bottom of the reactor, the cleaning plate remains hidden when cleaning is not required. In addition, the hidden cleaning plate will not interfere with the stirring and other operations during the reaction process when it is not in operation, ensuring the stability of the reaction conditions. In the process of producing catalysts, hydrogen is injected into the mixture inside the reactor to directly inject hydrogen into the mixture. This process not only helps the material to take shape, but also generates local turbulence by the rising of hydrogen, which further promotes the mixing of the material and ensures that the mixing is more uniform. When cleaning is required inside the reaction vessel, the hydrogen spraying section can be quickly switched to spraying cleaning fluid, saving space inside the reaction vessel while switching between the two states. During the cleaning process inside the reaction vessel, the cleaning plate adopts a flexible scraping method. When the cleaning plate encounters hard deposits, it can actively avoid hard contact with the deposits. With the elasticity of the cleaning plate, it can still actively reset after avoiding contact, thus protecting the cleaning plate while gradually reducing the particle size of the hard deposits.

Detailed Implementation

[0019] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0020] To address the issue that incompletely converted byproducts deposit at the bottom of the reactor during the reaction of mixed materials with hydrogen, and which adhere to the scraper of the cleaning system, existing high-pressure water jets, due to issues such as impact angle, disperse the energy of the water flow, reducing the impact force on the deposits and leading to incomplete cleaning that affects the quality of subsequent mixtures, this invention employs a concealed cleaning plate design. When cleaning the bottom of the reactor is not required, the cleaning plate does not protrude. Furthermore, when concealed, the cleaning plate does not interfere with stirring or other operations during the reaction process, helping to maintain stable reaction conditions.

[0021] Example 1: An apparatus and method for preparing a high-purity catalyst, such as... Figures 1-6As shown, it includes: a reaction vessel 10, which has a feed inlet and a discharge outlet, and a connecting frame 11 fixedly connected to the reaction vessel 10; a motor 12, which is disposed in the reaction vessel 10, and the drive shaft of the motor 12 passes through the reaction vessel 10 and is fixedly connected to a stirrer 13; a container shell 14, which is rotatably connected to the reaction vessel 10, and a cleaning plate 15 is slidably connected to the container shell 14; a connecting shell 16 is fixedly connected to the container shell 14; a gas guide shell 17 is fixedly connected to the connecting shell 16; and several sets of fixed plates 18 arranged in a ring array are fixedly connected to the gas guide shell 17. Each set of fixed plates 18 consists of two plates, and two adjacent fixed plates 18 are rotatably connected to a swing shell 19. The cleaning plate 15 is hidden in a concealed manner. When cleaning is required inside the holding shell 14, the cleaning plate 15 can be extended. The cleaning plate 15 is slidably connected to symmetrically distributed first sliding plates 151. A first spring is fixed between the first sliding plates 151 and the cleaning plate 15. The cleaning plate 15 is fixed to two symmetrically distributed limiting plates 152, which are used to limit the adjacent first sliding plates 151. Both the holding shell 14 and the cleaning plate 15 are provided with several through holes to reduce the resistance when they move relative to the mixed material. The driving component is set inside the air guide shell 17 to drive the cleaning plate 15 to slide. The air supply component is set on the connecting frame 11 to supply air into the air guide shell 17.

[0022] In the above scheme, the upper side of the cleaning plate 15 is initially attached to the lower side inside the container shell 14, and the through hole on the cleaning plate 15 is connected to the through hole on the container shell 14. This state is before the reactor 10 is cleaned. The cross section of the cleaning plate 15 is an inverted isosceles trapezoid, which is used to adapt to the shape of the lower side of the reactor 10, thus hindering the normal scraping of the cleaning plate 15. When it is necessary to clean the sediment in the reactor 10, the cleaning plate 15 can slide out from the container shell 14 and thus attach to the bottom inside the reactor 10. The length of the lower side of the cleaning plate 15 is less than the diameter inside the reactor 10. The first sliding plate 151 is used to increase the scraping area of ​​the cleaning plate 15 for the sediment. The fixing plate 18 is a circular plate. There are two connecting shells 16 in this invention, which are used to keep the container shell 14 stable during rotation.

[0023] like Figure 4 , Figure 5 and Figure 7 As shown, the drive assembly includes: an elastic liquid bladder 20, which is fixedly connected to the air guide shell 17; an oil holding shell 21 is fixedly connected to the lower side of the connecting shell 16; a sealing element 22 is slidably connected to the oil holding shell 21; the sealing element 22 is fixedly connected to the cleaning plate 15; an L-shaped tube that passes through the air guide shell 17 and the connecting shell 16 is fixedly connected to the elastic liquid bladder 20 and the oil holding shell 21; a second sliding plate 23 is slidably connected to the oil holding shell 21; and a second spring is fixedly connected between the second sliding plate 23 and the sealing element 22.

[0024] In the above scheme, the upper side of the seal 22 is sealed with the oil reservoir 21, while the lower side of the seal 22 is not sealed with the oil reservoir 21. The elastic liquid bladder 20, the L-shaped tube, and the oil reservoir 21 all contain liquid for transmission. After the elastic liquid bladder 20 is squeezed, the liquid in the elastic liquid bladder 20 enters the oil reservoir 21 through the L-shaped tube, which increases the pressure in the oil reservoir 21 and thus pushes the seal 22 to move. There is a gap between the upper side of the seal 22 and the second sliding plate 23 to provide additional space for the seal 22 to move.

[0025] like Figures 3-5 and Figures 7-10 As shown, the air supply assembly includes: a drive member 30, mounted on the connecting frame 11, with a hollow rod 31 rotatably connected to the telescopic end of the drive member 30. The hollow rod 31 passes through and is rotatably connected to the drive shaft of the motor 12. A first connecting pipe connected to the air guide shell 17 is fixedly connected to the hollow rod 31. The hollow rod 31 is fixedly connected to the adjacent side of the elastic liquid bladder 20 and splinedly connected to the holding shell 14. A fixed frame 32, fixedly mounted on the connecting frame 11, is slidably connected to a sliding shell 33. The sliding shell 33 is rotatably connected to and connected to a rotating shell 34. The rotating shell 34 is fixedly connected to and connected to the hollow rod 31. A sliding cylinder 35 is slidably connected inside the swing shell 19. A third spring is provided between the sliding cylinder 35 and the adjacent swing shell 19. A second connecting pipe is fixedly connected to and connected to the air guide shell 17. The sliding cylinder 35 is provided with several... The upper side of the swing housing 19 is provided with several air outlets 36. When the swing housing 19 is parallel to the horizontal plane, the connecting hole on the sliding cylinder 35 is connected to the air outlet 36. The air supply assembly also includes several liquid outlets 37, which are all provided on the lower side of the swing housing 19. When the swing housing 19 is perpendicular to the horizontal plane, the connecting hole on the sliding cylinder 35 is connected to the liquid outlet 37. The air outlets 36 and liquid outlets 37 are provided with nozzles. The symmetrically distributed fixed plates 18 are rotatably connected to a protective shell fixed to the swing housing 19. The fixed plates 18 are fixed with protrusions 38. The protective shell on the swing housing 19 is slidably connected to a sliding rod 39 fixed to the adjacent sliding cylinder 35. The sliding rod 39 slides along the outside of the protrusion 38. A connecting assembly is provided on the hollow rod 31. The connecting assembly is used to connect the hollow rod 31 and the drive shaft of the motor 12.

[0026] In the above scheme, the first connecting pipe on the hollow rod 31 is a bellows, the driving component 30 is an electric push rod, and a bearing splinedly connected to the hollow rod 31 can be installed between the drive shaft of the motor 12 and the hollow rod 31 to reduce friction between the drive shaft of the motor 12 and the hollow rod 31. The number of connecting holes on the upper side of the sliding cylinder 35 is the same as the number of upper air outlets 36, and the number of connecting holes on the lower side of the sliding cylinder 35 is the same as the number of lower liquid outlets 37. During the reaction, the mixture in the reactor 10 swings. When shell 19 is parallel to the horizontal plane, hydrogen gas can enter the outlet 36 through the connecting hole on the sliding cylinder 35 and be sprayed out from the outlet 36. When cleaning the inside of the reactor 10, the swing shell 19 is perpendicular to the horizontal plane. At this time, the cleaning liquid can enter the liquid outlet 37 through the connecting hole on the sliding cylinder 35 and be sprayed out from the nozzle in the liquid outlet 37. The protruding part of the protrusion 38 faces upward, so that after the swing shell 19 is perpendicular to the horizontal plane, the connecting hole on the sliding cylinder 35 can communicate with the liquid outlet 37.

[0027] like Figure 4 and Figure 7 As shown, the connecting assembly includes: a hinge seat 40, fixed to the upper side of the hollow rod 31, with a hinge rod 41 corresponding to the swing shell 19 hinged between the hinge seat 40 and the swing shell 19; and a ring array of limiting blocks 42, fixed to one end of the hollow rod 31 located inside the drive shaft of the motor 12. The drive shaft of the motor 12 is provided with a spline groove 43, which is used to limit the ring array of limiting blocks 42. The limiting blocks 42 are composed of equilateral triangular blocks and rectangular blocks, and the equilateral triangular blocks in the limiting blocks 42 face the spline groove 43 so that all the limiting blocks 42 can be inserted into the spline groove 43.

[0028] In the above scheme, during the upward movement of the hinge seat 40, all the hinge rods 41 on it pull the adjacent swing shell 19, so that all the swing shells 19 move synchronously, thereby completing the switching of the state inside the swing shell 19.

[0029] Working principle: Before the catalyst is prepared, the staff connects the external heating equipment and the external hydrogen supply equipment to the reactor 10 and the sliding shell 33 respectively, and then seals the discharge port of the reactor 10 to complete the preparation work before the catalyst is prepared.

[0030] After completing the preparation work before catalyst preparation, the staff put the raw materials, catalyst and additives required for the work (hereinafter collectively referred to as the mixture) into the reactor 10 through the feed port in sequence. When the liquid level of the mixture submerges the agitator 13 and is above it, the staff stops feeding.

[0031] After the mixture is placed, the operator starts the motor 12. The motor 12 drives the stirrer 13 to rotate in the mixture in the reactor 10 via the drive shaft. During this process, the external hydrogen supply device sends hydrogen into the sliding shell 33. The sliding shell 33 sends the hydrogen through the rotating shell 34 into the hollow rod 31. The hollow rod 31 sends the hydrogen through the two first connecting pipes on its upper side into the gas guide shell 17. The gas guide shell 17 sends the hydrogen through all the second connecting pipes on its upper side to the corresponding sliding cylinder 35. Then, the sliding cylinder 35 sends the hydrogen into all the gas outlets 36 on its upper side, so that the hydrogen is sprayed out from the nozzles in the gas outlets 36, thus completing the hydrogen injection operation.

[0032] During the rotation of the stirrer 13, the mixture in the reactor 10 is stirred. At this time, hydrogen gas sprayed from the nozzle in the outlet 36 enters the mixture in the reactor 10 and moves upward in the form of bubbles. (When the mixture reacts with hydrogen gas, byproducts that are not completely converted into the target product will be produced. These byproducts will be deposited at the bottom of the reactor 10 due to their own weight.)

[0033] During the rotation of the stirrer 13, it rotates along the upper side of the hollow rod 31. Since all the limiting blocks 42 do not contact the spline groove 43, the stirrer 13 will not drive the hollow rod 31 to rotate synchronously during the rotation. During the rotation of the stirrer 13, the mixing degree of the mixture in the reactor 10 is accelerated. When the mixture in the reactor 10 is stirred, it passes through the through holes on the container shell 14 and the cleaning plate 15. Through the through holes mentioned above, the interference to the mixture is reduced.

[0034] After the mixture is processed, it is converted into the high-purity catalyst required for the operation. At this point, the staff can shut off the electrical equipment mentioned above, and then discharge the high-purity catalyst from the discharge port on the lower side of the reactor 10 (the pressure must be released before discharge).

[0035] After the high-purity catalyst is discharged, the operator manipulates the drive component 30 to push its telescopic part upward. The upward movement of the telescopic part of the drive component 30 causes the hollow rod 31 to move synchronously (during the movement of the hollow rod 31, the sliding shell 33 slides along the fixed frame 32). During the upward movement of the hollow rod 31, the lower side of the elastic liquid bladder 20, the hinge seat 40, and all the limiting blocks 42 move upward (when the hollow rod 31 moves upward, the first connecting pipe is stretched). During the upward movement of the lower side of the elastic liquid bladder 20, the liquid inside is squeezed, causing the liquid to enter the oil-containing shell 21 through the L-shaped tube. The pressure inside the oil tank 21 increases, causing the second sliding plate 23 to move downward synchronously with the seal 22 via the second spring. During the movement of the seal 22, the cleaning plate 15 moves downward along the container shell 14, shortening the distance between the cleaning plate 15 and the bottom of the reactor 10. During the sliding of the cleaning plate 15, the two first sliding plates 151 move synchronously. Under the action of the first spring, the first sliding plate 151 moves towards the adjacent limiting plate 152 as the cleaning plate 15 slides. Through the sliding of the first sliding plate 151, the scraping area of ​​the cleaning plate 15 is expanded.

[0036] As the hollow rod 31 moves the hinge seat 40 upward, it pulls all the hinge rods 41, causing all the hinge rods 41 to drive the adjacent swing shells 19 to swing upward synchronously. During the swing, the swing shells 19 rotate along the two fixed plates 18. The sliding cylinder 35 and the sliding rod 39 swing upward synchronously with the swing shells 19. At this time, the sliding rod 39 is squeezed by the protrusion 38, causing the sliding rod 39 to drive the sliding cylinder 35 to slide away from the air guide shell 17 (the sliding cylinder 35 squeezes the third spring during the sliding process). During the sliding process, the sliding cylinder 35 gradually disconnects the connection between its upper connecting hole and the air outlet 36, and gradually connects the connecting hole on the sliding cylinder 35 with the liquid outlet 37.

[0037] When all the limiting blocks 42 move upward along with the hollow rod 31 and are inserted into the spline groove 43, the drive shaft of the motor 12 is "connected" with the hollow rod 31. At this time, all the swing shells 19 have swung to be perpendicular to the horizontal plane, and the state of all the swing shells 19 has been switched. At this time, the lower side of the cleaning plate 15 and the two first sliding plates 151 are completely in contact with the bottom of the reactor 10, and the connecting hole in the sliding cylinder 35 is connected to the liquid outlet 37. Through the above steps, the state of the parts is switched.

[0038] After the part state is switched, the air intake in the sliding shell 33 is changed to the cleaning fluid (the cleaning fluid is provided by an external liquid supply device). The operation of delivering the cleaning fluid is the same as the air supply operation steps described above. After the cleaning fluid is delivered into the sliding cylinder 35, it is sprayed out from the nozzles in all the liquid outlets 37. At this time, the operator controls the drive shaft of the motor 12 to rotate (this speed is slower than the speed during the previous stirring). The drive shaft of the motor 12 drives the hollow rod 31 to rotate through all the limit blocks 42. The hollow rod 31 drives the air guide shell 17 to rotate synchronously through the holding shell 14 and the connecting shell 16. During the rotation of the air guide shell 17, all the swing shells 19 are driven to rotate. During the rotation of the swing shells 19, the cleaning fluid cleans the inner wall of the reactor 10 in a circumferential rotation.

[0039] As the container shell 14 rotates along with the hollow rod 31, it drives the cleaning plate 15 and the two first sliding plates 151 to rotate synchronously. During the rotation of the cleaning plate 15, it scrapes the sediment at the bottom of the reactor 10. When the cleaning plate 15 encounters sediment with a hardness greater than that provided by the second spring on the sealing element 22 during the scraping process, the cleaning plate 15 is squeezed upward by the sediment, causing the cleaning plate 15 to drive the sealing element 22 to move slightly upward and squeeze the second spring on it, so as to realize the emergency avoidance of the cleaning plate 15. When the cleaning plate 15 stops scraping the hard sediment, the second spring on the sealing element 22 drives the cleaning plate 15 to move and reset. Through the continuous deformation of the second spring, the cleaning plate 15 scrapes the hard sediment step by step. The cleaned sediment and waste liquid are discharged from the discharge port on the lower side of the reactor 10.

[0040] After cleaning the sediment at the bottom of the reactor 10, the operator manipulates the telescopic part of the drive component 30 to move the hollow rod 31 downward. The hollow rod 31 moves the sliding shell 33, the lower side of the elastic liquid bladder 20, the hinge seat 40, and all the limiting blocks 42 downward synchronously. After the lower side of the elastic liquid bladder 20 moves downward, the pressure inside it decreases, causing the liquid in the oil tank 21 to flow back into the elastic liquid bladder 20 through the L-shaped tube. During the process of the liquid flowing back into the oil tank 21, the second sliding plate 23 and the second spring drive the sealing component 22 to reset. The sealing component 22 drives the cleaning plate 15 and the two first sliding plates 151 to move upward and reset. During the movement of the two first sliding plates 151, they are blocked by the two limiting plates 152, so that the two first sliding plates 151 move towards each other and squeeze the first spring respectively.

[0041] During the movement of the hinge seat 40, all the hinge rods 41 press against the adjacent swing shells 19, causing all the swing shells 19 to swing back to their original positions. All the limiting blocks 42 move downwards along with the hollow rod 31, thus disengaging from the spline groove 43. This disconnects the drive shaft of the motor 12 from the hollow rod 31. When all the above parts have returned to their original positions... Figure 6After the state is reached, the telescopic part of the drive component 30 stops moving. When the catalyst needs to be prepared again, the liquid inlet in the sliding shell 33 can be changed back to the gas inlet.

[0042] Example 2: Based on Example 1, a method for using a high-purity catalyst preparation apparatus includes the following steps: Step 1: First, connect the external heating device and the external hydrogen supply device to the reactor 10 and the sliding shell 33 respectively; Step 2: After completing the preparation work, put the raw materials, catalysts and additives required for the work into the reaction vessel 10; Step 3: The motor 12 drives the stirrer 13 to stir the mixture. The external hydrogen delivery device indirectly delivers hydrogen to the sliding cylinder 35 and sprays it out from the nozzle of the outlet 36. The hydrogen comes into contact with the mixture and produces a chemical reaction. Step 4: After stirring for a period of time, the mixture is converted into the high-purity catalyst required for the operation. Turn off the electrical equipment mentioned in the above steps and discharge the high-purity catalyst from the discharge port on the lower side of the reactor 10. Step 5: After the high-purity catalyst is discharged, the telescopic part of the drive component 30 extends and drives the hollow rod 31 to move synchronously. The hollow rod 31 drives the lower hinge seat 40 of the elastic liquid bladder 20 and all the limiting blocks 42 to move upward synchronously. Step 6: As the lower side of the elastic liquid bladder 20 moves upward, the pressure inside it increases. Through the transmission of the liquid, the pressure inside the oil-filled shell 21 increases, causing the seal 22 to drive the cleaning plate 15 to slide synchronously. Step 7: During the movement of the hinge seat 40, all the hinge rods 41 are brought together. During the process of bringing all the hinge rods 41 together, the protrusion 38 presses the sliding rod 39, and the sliding rod 39 drives the sliding cylinder 35 to change the communication state with the swing shell 19. Step 8: After the above parts have been switched, replace the air intake in the sliding shell 33 with cleaning fluid, so that the nozzle in the outlet 37 sprays out cleaning fluid to clean the inside of the reactor 10. Step 9: During the rotation of the hollow rod 31, the cleaning plate 15 is driven to scrape the bottom of the reactor 10. Through the third spring on the sealing element 22, the cleaning plate 15 scrapes the sediment step by step. The cleaned sediment and waste liquid are discharged from the discharge port on the lower side of the reactor 10. Step 10: After cleaning the sediment at the bottom of the reactor 10, the telescopic part of the drive component 30 drives the parts that move synchronously with the hollow rod 31 to reset one after another.
