Description

Technical Field

[0001] This utility model relates to the field of reaction vessels, and in particular to a reaction vessel suitable for granular catalysts. Background Technology

[0002] A reaction vessel is a closed container used for chemical reactions. In industrial production, catalysts are often used to modify the chemical reaction rate to meet the requirements of actual production. Different chemical reactions require different types of catalysts. When the viscosity of the raw materials in the reaction system is high, or the viscosity of the products is high, using powdered catalysts would increase the difficulty of separating the catalyst from the reaction system after the reaction, reduce production efficiency, and increase losses. Therefore, granular catalysts are often used.

[0003] Most common reaction vessels are suitable for mixing powdered raw materials or catalysts with liquid raw materials. If the particulate catalyst has low hardness, it is easily broken by the stirring paddle of the reaction vessel during the stirring process, and it is difficult to recover and reuse it after the reaction. If the particulate catalyst has high hardness, it is easy to get stuck between the stirring paddle and the inner wall of the reaction vessel, which can easily damage the reaction vessel during the stirring process. Utility Model Content

[0004] To reduce the damage to the reactor caused by particulate catalysts and to facilitate the recycling and replacement of particulate catalysts, this application provides a diatomaceous earth filter suitable for reactors with particulate catalysts and an easily replaceable filter plate.

[0005] This application provides a reaction vessel suitable for granular catalysts, employing the following technical solution:

[0006] A reactor suitable for granular catalysts includes a reactor body, a top cover adapted to the reactor body, a cover opening assembly for vertically moving the top cover, a second support column for supporting the cover opening assembly, and a first support column for supporting the second support column. The top cover has a feed inlet, and a stirring motor is fixedly connected to the top cover. The output shaft of the stirring motor passes through the top cover and is fixedly connected to a frame-type stirring paddle. The frame-type stirring paddle includes a horizontal plate, two vertical plates, and a curved plate. The vertical plates are fixedly connected between the horizontal plates and the curved plates. Catalyst chambers are respectively arranged on both sides of the vertical plates in the thickness direction. The catalyst chambers are detachably connected to the vertical plates through a disassembly assembly. The catalyst chambers are evenly provided with a plurality of filter holes. The lower end of the reactor body is fixedly connected to a support leg, and the lower end of the reactor body has a discharge port.

[0007] By adopting the above technical solution, the raw materials enter the reactor through the feed inlet, and the products are discharged from the outlet after the reaction. The catalyst chamber is detachably connected to the vertical plate, and the granular catalyst is placed in the catalyst chamber. When the reactor is working, the catalyst chamber moves together with the frame-type agitator, making full contact with the liquid in the reactor and catalyzing the reaction. The granular catalyst does not mix with the liquid, which can reduce the damage of the granular catalyst to the reactor and also reduce the probability of the granular catalyst being broken by the frame-type agitator. After the reaction, the cover opening component raises the top cover, which drives the frame-type agitator and the catalyst chamber to rise together, making it convenient for workers to replace the granular catalyst and making the granular catalyst easy to recover and replace.

[0008] Optionally, the catalyst chamber is semi-cylindrical and includes a rectangular plate, an arc-shaped plate, and two semi-circular base plates. One side of each base plate is hinged to the rectangular plate, and the other side of each base plate is detachably connected to the arc-shaped plate via a snap fastener.

[0009] By adopting the above technical solution, when workers need to replace the granular catalyst, they only need to open one side of the bottom plate, pour out the used catalyst, and then fill in the new catalyst; both bottom plates of the catalyst chamber can be opened, making it convenient for workers to clean the catalyst chamber.

[0010] Optionally, the disassembly assembly includes several dovetail-shaped protrusions and several sets of snap-fit ​​grooves. The protrusions and snap-fit ​​grooves correspond one-to-one. The protrusions are fixedly connected to the vertical plate and are distributed along the vertical direction. The snap-fit ​​grooves are located on the side of the rectangular plate away from the curved plate and are distributed along the length of the rectangular plate. The snap-fit ​​grooves include a first snap-fit ​​groove and a second snap-fit ​​groove. The first snap-fit ​​groove is adapted to the protrusion, and the width of the second snap-fit ​​groove is equal to the width of the wide end of the protrusion. The first snap-fit ​​groove is located above the second snap-fit ​​groove and is connected to the second snap-fit ​​groove.

[0011] By adopting the above technical solution, workers can align the protrusions on the vertical plate with the second locking groove on the rectangular plate, and then apply a downward force to the catalyst chamber, causing the protrusions to enter the first locking groove. The protrusions act as a horizontal limit for the catalyst chamber, thereby fixing its position. When it needs to be removed, the rectangular plate is lifted upwards to remove the catalyst chamber, thus enabling the replacement of the catalyst chamber and improving work efficiency.

[0012] Optionally, the rectangular plate is detachably connected to a first positioning block, the first positioning block being adapted to a second snap-fit ​​groove, and a positioning groove being provided on the lower end face of the rectangular plate for the first positioning block to pass through, the positioning groove being connected to the second snap-fit ​​groove.

[0013] By adopting the above technical solution, after the worker fixes the catalyst chamber on the vertical plate, the first positioning block can be installed in the second snap-fit ​​groove through the positioning groove, making the connection between the catalyst chamber and the vertical plate more stable. This prevents the catalyst chamber from falling off the vertical plate due to the influence of the liquid in the reactor when the frame-type agitator rotates, thus affecting the normal operation of the frame-type agitator.

[0014] Optionally, the end of the first positioning block away from the second locking slot is fixedly connected to the second positioning block.

[0015] By adopting the above technical solution, the second positioning block makes it easier for workers to apply force to the first positioning block. Through the second positioning block, workers can more easily pick up the first positioning block, making the installation and removal of the first positioning block more convenient and efficient.

[0016] Optionally, a first indicator line is marked on one side of each of the two vertical plates that are opposite to each other, and the first indicator line is flush with the lower end face of the lowest protrusion; a second indicator line is marked on both sides of the rectangular plate along the width direction, and the second indicator line and the junction of the second snap-fit ​​groove and the positioning groove are at the same height.

[0017] By adopting the above technical solution, when workers need to install the catalyst chamber on the vertical plate, they only need to align the first indicator line with the second indicator line and then push the catalyst chamber towards the vertical plate, so that several protrusions can simultaneously enter the corresponding second locking grooves, thus improving work efficiency.

[0018] Optionally, the lower part of the first support column is fixedly connected to the outside of the vessel body. The lid opening assembly includes a lid opening motor, a crossbeam, and two fixed rods. The second support column has a second groove. The lid opening motor is fixedly connected to the second support column and is located in the second groove. The output shaft of the lid opening motor is fixedly connected to a threaded rod. The threaded rod passes through the crossbeam and is threadedly connected to the crossbeam. The threaded rod is located in the second groove and is rotatably connected to the second support column. One end of each of the two fixed rods is fixedly connected to the crossbeam, and the other end of each of the two fixed rods is fixedly connected to the upper cover.

[0019] By adopting the above technical solution, when the catalyst chamber needs to be replaced, the worker can start the cover-opening motor. The cover-opening motor drives the top cover, frame-type agitator, and catalyst chamber to move upward, so that the frame-type agitator and catalyst chamber are removed from the reactor body. The worker can replace the catalyst chamber from the outside of the reactor body without having to put their hands into the reactor body, making the replacement of the catalyst chamber more convenient.

[0020] Optionally, the first support column has a first groove on its upper part, a rotating motor is fixedly connected to the first support column and the rotating motor is located in the first groove, the output shaft of the rotating motor is fixedly connected to the upper end of the second support column, the first support column has a positioning hole that communicates with the first groove, and a positioning shaft that matches the positioning hole is fixedly connected to the lower end of the second support column. The positioning shaft is located in the positioning hole and is coaxially arranged with the output shaft of the rotating motor.

[0021] By adopting the above technical solution, after the opening assembly moves the top cover, frame-type agitator, and catalyst chamber upward out of the reactor body, the worker starts the rotating motor. The rotating motor drives the second support column to rotate, so that the opening assembly, top cover, frame-type agitator, and catalyst chamber rotate out from the top of the reactor body at the same time. Subsequently, the opening assembly starts again, driving the frame-type agitator and catalyst chamber downward to a height that is convenient for workers to operate, avoiding workers climbing to operate and reducing safety hazards.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The catalyst chamber is detachably connected to the vertical plate and the outer wall of the catalyst chamber is evenly provided with several through holes, so that when the reactor is working, the catalyst chamber can move together with the frame-type stirring paddle. The liquid in the reactor can fully contact the granular catalyst through the through holes. The granular catalyst does not mix with the liquid, which reduces the chance of the granular catalyst damaging the inner wall of the reactor and also reduces the chance of the granular catalyst being broken by the frame-type stirring paddle.

[0024] 2. By setting up disassembly components and indicator lines, when workers need to install the catalyst chamber on the vertical plate, they only need to align the first indicator line with the second indicator line and then push the catalyst chamber towards the vertical plate. This allows several protrusions to simultaneously enter the corresponding second snap-fit ​​slots, making catalyst chamber replacement more convenient and efficient, and improving work efficiency.

[0025] 3. With the opening assembly and rotating motor, after the opening assembly moves the top cover, frame-type agitator, and catalyst chamber upward out of the reactor body, the worker starts the rotating motor. The rotating motor drives the second support column to rotate, so that the opening assembly, top cover, frame-type agitator, and catalyst chamber rotate out from the top of the reactor body at the same time. Then, the opening assembly starts again, moving the frame-type agitator and catalyst chamber downward to a height that is easy for the worker to operate, avoiding the need for the worker to climb to operate and reducing safety hazards.

[0033] The present application will be further described in detail below with reference to all the accompanying drawings.

[0034] This application discloses a reaction vessel suitable for particulate catalysts. Example

[0035] Reference Figure 1A reaction vessel suitable for granular catalysts includes a vessel body 1, a top cover 2 adapted to the vessel body 1, a cover opening assembly 3 for vertically moving the top cover 2, a second support column 32 for supporting the cover opening assembly 3, and a first support column 31 for supporting the second support column 32. A stirring motor 22 is fixedly connected to the top cover 2, and the top cover 2 supports the stirring motor 22. The output shaft of the stirring motor 22 passes through the top cover 2 and is fixedly connected to a frame-type stirring paddle 23. After the stirring motor 22 is started, it drives the frame-type stirring paddle 23 to rotate, thus mixing the liquid inside the reaction vessel. 23 includes a horizontal plate 231, two vertical plates 232, and a curved plate 233. The vertical plates 232 are fixedly connected between the horizontal plate 231 and the curved plate 233. The horizontal plate 231, the two vertical plates 232, and the curved plate 233 support each other to ensure the stability of the frame-type stirring paddle 23 when it rotates and the mixing effect on the reaction system. The upper cover 2 has a feed inlet 21. Before the reaction starts, the material is fed through the feed inlet 21. The lower end of the vessel body 1 has a discharge outlet 12. After the reaction is completed, the material is discharged through the discharge outlet 12. The lower end of the vessel body 1 is fixedly connected to a support leg 11, which supports the vessel body 1.

[0036] Reference Figure 2 The catalyst chamber 4 includes a rectangular plate 41, an arc-shaped plate 42, and two semi-circular base plates 43. Workers can fill the catalyst chamber 4 with granular catalyst. One side of each base plate 43 is hinged to the rectangular plate 41, and the other side of each base plate 43 is detachably connected to the arc-shaped plate 42 via a buckle 44. Before using the catalyst chamber 4, the worker opens one base plate 43, fills the catalyst chamber 4 with granular catalyst, and then closes the base plate 43 to prevent the granular catalyst from falling out of the catalyst chamber 4 during use and to reduce the chance of the granular catalyst being broken by the frame-type stirring paddle 23. Both base plates 43 of the catalyst chamber 4 are detachably connected to the arc-shaped plate 42. When the catalyst chamber 4 needs to be cleaned, the worker can open both base plates 43 completely to make the catalyst chamber 4 easy to clean.

[0037] Reference Figure 1 and Figure 3The lower part of the first support column 31 is fixedly connected to the outside of the vessel body 1, and the vessel body 1 supports the first support column 31. The lid opening assembly 3 includes a lid opening motor 33, a crossbeam 34, and two fixing rods 35. The second support column 32 has a second groove 321. The lid opening motor 33 is fixedly connected to the second support column 32, and the second support column 32 supports the lid opening motor 33. The lid opening motor 33 is located in the second groove 321. The output shaft of the lid opening motor 33 is fixedly connected to a threaded rod 36. After the lid opening motor 33 is started, it drives the threaded rod 36 to rotate. A crossbeam 34 is threaded through and connected to the crossbeam 34. A threaded rod 36 is located in the second groove 321 and is rotatably connected to the second support column 32. The second groove 321 limits the horizontal movement of the crossbeam 34. The rotation of the threaded rod 36 drives the crossbeam 34 to move vertically. One end of each of the two fixed rods 35 is fixedly connected to the crossbeam 34, and the other end of each of the two fixed rods 35 is fixedly connected to the top cover 2. The fixed rods 35 connect the crossbeam 34 and the top cover 2 together. After the opening motor 33 is started, it can drive the crossbeam 34 and the top cover 2 to move synchronously in the vertical direction.

[0038] Reference Figure 3 and Figure 4 The first support column 31 has a first groove 311 on its upper part. A rotating motor 61 is fixedly connected to the first support column 31 and is located within the first groove 311. The first support column 31 supports the rotating motor 61. The output shaft of the rotating motor 61 is fixedly connected to the upper end of the second support column 32, which is located within the first groove 311. After the rotating motor 61 is started, it drives the second support column 32 to rotate. A positioning shaft 62 is fixedly connected to the lower end of the second support column 32. When the second support column 32 rotates, the positioning shaft 62 rotates synchronously. The first support column 31 has a positioning hole 63, which is connected to the first groove 311. The lower end of the second support column 32 is fixedly connected to a positioning shaft 62 that is adapted to the positioning hole 63. The positioning shaft 62 is located in the positioning hole 63. The positioning hole 63 limits the positioning shaft 62 in the horizontal direction, and thus cooperates with the rotating motor 61 to fix the position of the second support column 32. The positioning shaft 62 is coaxially arranged with the output shaft of the rotating motor 61. When the rotating motor 61 is started, it can drive the second support column 32, the crossbeam 34, and the upper cover 2 to rotate synchronously.

[0039] Reference Figure 1 and Figure 3Catalyst chambers 4 are respectively provided on both sides of the vertical plate 232 in the thickness direction. The catalyst chambers 4 are detachably connected to the vertical plate 232 via a disassembly assembly. Before the reaction begins, the worker installs an appropriate number of catalyst chambers 4 on the vertical plate 232 as needed. When installing the catalyst chambers 4, the worker first starts the cover-opening motor 33, which drives the crossbeam 34, the upper cover 2, and the frame-type stirring paddle 23 to rise until the frame-type stirring paddle 23 leaves the reactor body 1. Then, the worker starts the rotation motor 61, which drives the second support column 32, the crossbeam 34, the upper cover 2, and the frame-type stirring paddle 23 to rise. The agitator 23 rotates out from above the vessel body 1, the rotating motor 61 stops working, and the opening motor 33 restarts, driving the crossbeam 34, the upper cover 2, and the frame agitator 23 to a height that is convenient for the worker to operate at, so that the catalyst chamber 4 can be installed. In this way, the worker can replace the catalyst chamber 4 from outside the vessel body 1 without having to put his hand into the vessel body 1 or climb to operate, which improves work efficiency and reduces safety hazards. After installation, the opening motor 33 and the rotating motor 61 work together to make the frame agitator 23 return to the vessel body 1 and close the upper cover 2.

[0040] Reference Figure 1 After the reaction begins, the catalyst chamber 4 rotates synchronously with the frame-type stirring paddle 23. The catalyst chamber 4 is semi-cylindrical, which reduces the resistance between the catalyst chamber 4 and the liquid when it rotates, thus extending the service life of the frame-type stirring paddle 23. The catalyst chamber 4 is evenly provided with several filter holes. When the catalyst chamber 4 rotates, the liquid comes into contact with the granular catalyst through the filter holes, and the catalyst plays a catalytic role in the reaction. When the catalyst needs to be replaced, the worker removes the catalyst chamber 4 from the vertical plate 232 to replace the catalyst. Therefore, when the reactor is working, the granular catalyst does not mix with the liquid, the granular catalyst is easy to recover and replace, and the damage of the granular catalyst to the reactor can also be reduced.

[0041] Reference Figure 2 and Figure 5The disassembly assembly includes several dovetail-shaped protrusions 51 and several sets of snap-fit ​​grooves. Each protrusion 51 corresponds to one of the snap-fit ​​grooves, and the snap-fit ​​grooves limit the horizontal movement of the protrusions 51. The disassembly assembly is located on both sides of the vertical plate 232 along its thickness. Workers can determine the number of catalyst chambers 4 installed on the frame-type stirring paddle 23 according to actual reaction needs, thus meeting the catalyst weight requirements of different reaction systems. The protrusions 51 are fixedly connected to the vertical plate 232 and are distributed vertically to fix the position of the catalyst chambers 4. The snap-fit ​​grooves are located on the side of the rectangular plate 41 away from the arc-shaped plate 42 and are distributed along the length of the rectangular plate 41. This arrangement places the protrusions 51 on the vertical plate 232 and the snap-fit ​​grooves on the rectangular plate 41, preventing damage to the vertical plate 232. The groove on plate 32 weakens the strength of the frame-type agitator 23 and shortens its service life. The locking groove assembly includes a first locking groove 52 and a second locking groove 53. The first locking groove 52 is adapted to the protrusion 51 to fix the position of the protrusion 51. The width of the second locking groove 53 is equal to the wide end of the protrusion 51 to facilitate the passage of the protrusion 51. The first locking groove 52 is located above the second locking groove 53 and is connected to the second locking groove 53. The worker aligns the protrusion 51 with the corresponding second locking groove 53 and pushes the catalyst chamber 4 towards the vertical plate 232 so that the protrusion 51 enters the second locking groove 53. Then, a downward force is applied to the catalyst chamber 4 so that the locking groove assembly and the protrusion 51 move relative to each other and the protrusion 51 enters the first locking groove 52, thereby fixing the position of the catalyst chamber 4.

[0042] Reference Figure 1 and Figure 5 The rectangular plate 41 is detachably connected to a first positioning block 55, which is adapted to the second locking groove 53. After the worker fixes the catalyst chamber 4 on the vertical plate 232, the first positioning block 55 can be installed in the second locking groove 53. The first positioning block 55 and the first locking groove 52 cooperate to limit the catalyst chamber 4 in the vertical direction. When the catalyst chamber 4 rotates with the frame-type agitator 23, the first positioning block 55 can make the connection between the catalyst chamber 4 and the vertical plate 232 more stable, and prevent the catalyst chamber 4 from falling off the vertical plate 232 and affecting the normal operation of the frame-type agitator 23. The end of the first positioning block 55 away from the second locking groove 53 is fixedly connected to a second positioning block 56. The second positioning block 56 makes it easier for the worker to apply force to the first positioning block 55, making it easier for the worker to pick up the first positioning block 55.

[0043] Reference Figure 6The lower end face of the rectangular plate 41 is provided with a positioning groove 54 for the first positioning block 55 to pass through. The positioning groove 54 is connected to the second snap-fit ​​groove 53. The worker can install the first positioning block in the second snap-fit ​​groove 53 through the positioning groove 54. The installation of the first positioning block can be achieved in various ways. This application uses bolt connection. Both sides of the rectangular plate 41 in the width direction are provided with through holes 71, and both sides of the first positioning block 55 in the length direction are provided with threaded holes 72. Both sides of the first positioning block 55 in the length direction are threaded with positioning bolts 73. The positioning bolts 73, threaded holes 72, and through holes 71 correspond one-to-one. After the first positioning block 55 enters the second snap-fit ​​groove 53, the corresponding threaded holes 72 and through holes 71 are connected to each other. The worker screws the positioning bolts 73 into the corresponding threaded holes 72, thereby fixing the position of the first positioning block 55 and making the connection between the catalyst chamber 4 and the vertical plate 232 more stable.

[0044] Reference Figure 2 and Figure 6 The two vertical plates 232 are marked with a first indicator line 57 on their opposite sides, and the first indicator line 57 is flush with the lower end face of the protrusion 51 at the bottom. The rectangular plate 41 is marked with a second indicator line 58 on both sides along its width direction. The second indicator line 58 and the junction of the second locking groove 53 and the positioning groove 54 are at the same height. When the worker installs the catalyst chamber 4, the protrusion 51 and the locking groove are not at the same height, which makes the installation of the catalyst chamber 4 inconvenient. After setting the first indicator line 57 and the second indicator line 58, when the worker installs the catalyst chamber 4, he only needs to place the first indicator line 57 and the second indicator line 58 at the same height, and then move the catalyst chamber 4 closer to the vertical plate 232 so that the protrusion 51 can enter the corresponding second locking groove 53, which makes it easier for the worker to install the catalyst chamber 4 and improves work efficiency.

[0045] Reference Figure 1 and Figure 3 After the catalyst chamber 4 is installed, the frame-type agitator 23, in coordination with the cover-opening motor 33 and the rotating motor 61, returns to the reactor body 1. Simultaneously, the cover-opening motor 33 closes the top cover 2, and the raw materials enter the reactor through the feed inlet 21. The worker starts the agitator motor 22, and the reaction begins. After the reaction is complete, the agitator motor 22 stops, and the product is discharged through the discharge outlet 12. If cleaning of the reactor interior is required, clean water can be added to the reactor through the feed inlet 21, and the agitator motor 22 can be started to clean the reactor interior. After cleaning, the agitator motor 22 stops, and the water flows out through the discharge outlet 12, thus completing the cleaning of the reactor. If it is necessary to replace or add catalyst, the worker only needs to start the cover-opening motor 33 and the rotating motor 61 to remove the frame-type agitator 23 from the reactor, replace the catalyst chamber 4, and then return the frame-type agitator 23.

[0046] The implementation principle of a reaction vessel suitable for granular catalysts in this application embodiment is as follows: the catalyst chamber 4 is detachably connected to the vertical plate 232 via a disassembly assembly. The granular catalyst is filled in the catalyst chamber 4, reducing the probability of the granular catalyst being broken by the frame-type stirring paddle 23 and mitigating the damage to the reaction vessel caused by the granular catalyst. The cover-opening motor 33 and the rotation motor 61 allow workers to replace the catalyst chamber 4 from outside the vessel body 1 without having to put their hands into the vessel body 1 or climb to operate, thus improving work efficiency and reducing safety hazards. After the stirring motor 22 is started, it drives the catalyst chamber 4 to rotate synchronously with the frame-type stirring paddle 23. The catalyst chamber 4 is evenly provided with several through holes 71. When the catalyst chamber 4 rotates, the liquid comes into contact with the granular catalyst through the through holes 71, and the catalyst plays a catalytic role in the reaction.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
