Description

Technical Field

[0001] This utility model relates to the field of solid particle processing technology, and in particular to an automated micro-catalyst granulation device. Background Technology

[0002] In the field of chemical machinery, catalyst granulation equipment is an important piece of equipment used to process catalyst raw materials into particles with specific shapes and sizes. It involves multiple aspects such as mechanical design, manufacturing, and automated control to achieve an efficient and stable granulation process. Currently, common catalyst granulation technologies include compression molding, extrusion molding, rotational molding, and spray drying molding. Compression molding places powder with a certain moisture content in a closed mold, and external pressure causes the powder to agglomerate and form a product with uniform particle size and shape. However, the mold wears quickly, and maintenance costs are high. It is suitable for the production of particle catalysts with high metal oxide content. Extrusion molding involves kneading powder with additives and feeding it into an extruder. Under extrusion pressure, the material is extruded from the die orifice to produce a product of a specific shape. Single-screw extruders have a simple structure and low cost, but the material is prone to sticking to the screw. Twin-screw extruders can avoid the screw sticking phenomenon and are suitable for the production of strip-shaped catalysts with high viscosity. Rotational molding involves adding powder and water or binder to a rotating container. Under the action of various forces, the powder agglomerates and grows into spherical particles. It has a large throughput but produces a lot of dust. It is used for the production of various spherical molecular sieves and catalysts. Spray drying molding uses an atomizer to disperse the raw material slurry into droplets, which are then dried with hot air into powder or microsphere products. It is suitable for fluidized bed reactors, but the equipment investment and operating costs are relatively high. Although existing technologies can meet some production needs, with the development of high-throughput catalyst synthesis equipment, there is still a more urgent need to improve catalyst granulation devices in terms of mg to g-level micro-granulation.

[0003] Chinese Patent Publication No. CN221656508U discloses a catalyst granulation device, comprising: a bottle cap and a bottle body; the bottle cap is located at the upper part of the bottle body and is detachably connected to the bottle body; several cylinders are arranged on the inner side of the top of the bottle cap, and the cylinders are fixedly connected to the bottle cap; an extrusion plate is arranged on the output shaft of the cylinders, and an extrusion auxiliary component is arranged below the extrusion plate; the bottle body is located at the lower part of the bottle cap and is detachably connected to the bottle cap; the bottle body includes a support platform, several support rods, smooth iron pillars, several blades, a buffer groove, a solenoid valve, and a drying fan; a support platform is arranged on the inner edge of the bottle body, and the support platform is used to support the granulation mold. Therefore, the catalyst granulation device has the following problems:

[0004] The production of granular catalysts of different sizes, ranging from mg to g in trace quantities, cannot meet the particle size requirements, resulting in catalyst forming rate verification results that are lower than the required range, thus affecting the automation efficiency of trace catalyst granulation. Utility Model Content

[0005] Therefore, this utility model provides an automated micro-catalyst granulation device to overcome the problems in the prior art where granular catalysts of different sizes produced cannot meet the particle size requirements at the mg to g level and lack catalyst forming rate verification.

[0006] To achieve the above objectives, this utility model provides an automated micro-catalyst granulation device, comprising:

[0007] The compression module, including a tableting vessel and a tableting device, is used to compress catalyst powder in the tableting vessel into catalyst tablets;

[0012] Furthermore, the tableting apparatus includes:

[0013] The protective mechanism is rectangular in shape with a square notch at the bottom. It consists of a top protective plate, side protective plates, and a back protective plate, and is used to protect the servo mechanism and tablet pressing mechanism inside the tablet pressing device.

[0014] The support mechanism consists of a top plate and a bottom plate. The top plate and the bottom plate are fixedly connected to the middle and bottom of the protective mechanism, respectively, and are connected to the side protective plate and the back protective plate. The bottom plate is vertically provided with four support columns connected to the bottom of the top plate to support the top plate. The top plate is used to support the servo mechanism.

[0015] Furthermore, the servo mechanism is located at the top of the top plate, passes through the top plate and is connected to the tablet pressing mechanism. The servo mechanism can control the tablet pressing mechanism to move in the vertical direction by telescoping.

[0016] Furthermore, the tablet pressing mechanism comprises, from top to bottom, a first mounting base assembly, a first adapter assembly, a sensing assembly, a second adapter assembly, a second mounting base assembly, and a pressing head assembly.

[0017] Furthermore, the first mounting bracket and the second mounting bracket are respectively used to mount the sensing component and the pressure head component;

[0018] The pressure head assembly consists of a replaceable first pressure head assembly and a second pressure head assembly, which are used to press the catalyst in the tableting vessel of different diameters, respectively.

[0019] The base plate is provided with a slide rail assembly, and the fixture mechanism can slide horizontally through the slide rail assembly. The fixture mechanism is used to support the tableting vessels of different diameters.

[0020] Furthermore, the grinding and screening module also includes:

[0021] A vibration platform, located at the bottom of the grinding station, is used to vibrate horizontally to cause the catalyst powder in the second layer of filter screens to leak to the bottom layer of filter screen.

[0022] The grinding mechanism, located at the top of the vibration platform, is used to transmit the vibration amplitude of the vibration platform to the second-layer filter screen.

[0023] Furthermore, the grinding mechanism includes four pillars vertically connected to the top of the vibration platform, through which the vibration platform transmits the vibration amplitude to the second-layer filter screen;

[0024] The support column is fixedly and penetratingly connected to three layers of inspection sieve trays from top to bottom. The inspection sieve trays are square sheet structures with a circular through hole in the center.

[0025] A filter screen support is provided above the three-layer test sieve tray, which is used to support the three-layer filter screen.

[0028] Compared with the prior art, the beneficial effects of this utility model are that this device fills the gap in mg and g-level automated micro-catalyst granulation equipment, and has the advantages of fast granulation speed, good repeatability and high efficiency by applying automatic granulation method.

[0029] Furthermore, this device completes a series of complex actions such as tilting, shaking, placing, grinding, picking up, and cleaning by clamping and moving modules, accurately positioning the container and filter screen to achieve unmanned and fully automatic operation, which is the fundamental guarantee of a high degree of automation.

[0030] Furthermore, the dedicated clamping mechanism can reliably clamp various tooling (vessels, grinding heads, filters) of different shapes and sizes, and has strong versatility. After the robotic arm clamps the vessel, it performs a "shaking back and forth" action to simulate manual operation, so that the catalyst powder is evenly spread before tableting. This is an important step to ensure consistent tableting density and avoid cracking, which directly affects the molding quality.

[0031] Furthermore, the three-layer filter design enables fine classification of the ground catalyst powder. The top coarse screen is used for preliminary crushing and filtering of large particles, the middle target screen is used to obtain the finished product with the target particle size, and the bottom screen is used to collect and confirm the yield of the finished product. The three-layer filter structure is scientifically designed and has high screening efficiency. At the same time, this device uses horizontal vibration instead of vertical impact or strong grinding, which can effectively reduce the damage to the microstructure of the catalyst itself (such as avoiding crystal destruction or reduction of active sites). Meanwhile, the continuous vibration force allows qualified powder to pass through the sieve smoothly, combining efficiency and protection.

[0032] Furthermore, the press head assembly adopts a replaceable design, and with a sliding and switchable fixture mechanism, it can quickly adapt to tableting vessels of different diameters, reducing adjustment time when changing samples and improving efficiency.

[0033] Furthermore, the structure of the support pillars and the inspection sieve tray ensures that vibration energy can be efficiently and evenly transmitted to each layer of the filter screen, preventing energy attenuation from reducing the screening efficiency of the lower layers. The raised design of the filter screen support facilitates gripping and placement by the robotic arm. This invention processes powdered catalyst raw materials into granular catalysts with uniform particle size and suitable strength through specific processes and equipment to meet the performance requirements of catalysts in different industrial production processes, thereby improving the activity, selectivity, and stability of the catalyst.

[0046] This utility model provides an automated micro-catalyst granulation device, comprising:

[0047] The compression module includes a tableting vessel 1 and a tableting device, used to compress the catalyst powder in the tableting vessel 1 into catalyst tablets;

[0048] Specifically, the tablet press is designed with different diameters to accommodate catalyst powders of different weights, thus improving the equipment's versatility and ability to handle different experimental needs.

[0049] The clamping and moving module consists of a moving mechanism and a clamping mechanism. The clamping mechanism is connected to the moving mechanism. The clamping mechanism is used to clamp the tableting vessel 1. The moving mechanism is used to drive the clamping mechanism to move. The clamping and moving module can put the tableting vessel 1 into the tableting device and pour the catalyst tablets in the tableting vessel 1 into the grinding and screening module.

[0050] In this embodiment, the moving mechanism is a six-axis robotic arm, which is equipped with an integrated vision system;

[0051] The moving mechanism includes a base 91, a rotating component, and an output end 97. The base 91 is used to fix and support the moving mechanism. The rotating component is used to rotate and move the base 91 around a plurality of axes. The output end 97 is used to connect to the clamping mechanism.

[0052] Specifically, the base 91 is sequentially connected to the waist assembly 92 of the rotating component, the upper arm assembly 93, the forearm front assembly 94 and the forearm rear assembly 95, the wrist assembly 96 and the output end 97.

[0053] Specifically, the clamping and moving module is the core advantage of this invention, capable of performing a series of complex actions such as tilting, shaking, placing, grinding, picking up, and cleaning. The integrated vision system gives it "eyes," enabling precise positioning of containers and filters, achieving unmanned, fully automated operation, which is the fundamental guarantee of a high degree of automation.

[0054] The clamping mechanism includes a flange 11, a claw tool base 12, and a clamping assembly. The clamping assembly is used to clamp the tableting vessel 1. The flange 11 is connected to the output end 97, and the claw tool base 12 is used to connect the flange 11 and the clamping assembly.

[0055] Specifically, the clamping assembly consists of a fingertip assembly 13 and a finger clamping assembly 14.

[0056] The dedicated clamping mechanism can reliably clamp various tooling (vessels, grinding heads, filters) of different shapes and sizes, making it highly versatile.

[0057] During implementation, the robotic arm pours solid granules into tableting container 1, which is lined with tin foil. The robotic arm picks up tableting container 1 and shakes it back and forth 3-5 times to spread the solid granules evenly inside the tableting container 1. The robotic arm then picks up tableting container 1 and places it on the tableting device for tableting. Tableting containers 1 are divided into different diameters depending on the weight of the granules being tableted.

[0058] After the robotic arm picks up the container, it performs a "shaking back and forth" motion to simulate manual operation, so that the catalyst powder is evenly spread before tableting. This is an important step to ensure consistent tablet density and avoid cracking, which directly affects the molding quality.

[0059] The grinding and screening module includes a three-layer filter screen and a vibration platform 71. The clamping and moving module can grind the catalyst tablets into catalyst powder through the three-layer filter screen, and the vibration platform 71 can screen the catalyst powder that meets the particle size requirements through vibration filtration.

[0060] The three-layer filter design enables fine classification of the ground catalyst powder. The top coarse mesh is used for initial crushing and filtering of large particles, the middle target mesh is used to obtain the finished product with the target particle size, and the bottom mesh is used to collect and confirm the product yield. The three-layer filter structure is scientifically designed and has high screening efficiency.

[0061] Using horizontal vibration instead of vertical impact or strong grinding can effectively reduce damage to the microstructure of the catalyst itself (such as avoiding crystal destruction or reduction of active sites), while relying on continuous vibration force to ensure that qualified powder passes through the sieve smoothly, thus combining efficiency and protection.

[0062] During implementation, the robotic arm pours the catalyst tablets into the top layer filter screen, and then grinds them by crushing them along a customized trajectory using a grinding head. The top layer filter screen has 81 mesh sizes of 300 microns, and the middle layer filter screen has 82 mesh sizes of 160 microns. The number of tableting cycles is determined based on the actual screening results.

[0063] Specifically, this device fills the gap in automated micro-catalyst granulation equipment at the mg and g levels. It employs an automated granulation method and has advantages such as fast granulation speed, good repeatability, and high efficiency.

[0064] The tableting device includes a protective mechanism, a support mechanism, a servo mechanism 4, a tableting mechanism, and a fixture mechanism 62;

[0065] The protective mechanism is rectangular in shape with a square notch at the bottom. It consists of a top protective plate 21, a side protective plate 22, and a back protective plate 23, and is used to protect the servo mechanism 4 and the tablet pressing mechanism inside the tablet pressing device.

[0066] In practice, the square notch is used by the robotic arm to feed in and remove the tablet press 1.

[0067] The support mechanism consists of a top plate 31 and a bottom plate 32. The top plate 31 and the bottom plate 32 are fixedly connected to the middle and bottom of the protective mechanism, respectively, and are connected to the side protective plate 22 and the back protective plate 23. The bottom plate 32 is vertically provided with four support columns 33, which are connected to the bottom of the top plate 31 to support the top plate 31. The top plate 31 is used to support the servo mechanism 4.

[0068] The servo mechanism 4 is located on the top of the top plate 31, passes through the top plate 31 and is connected to the tablet pressing mechanism. The servo mechanism 4 can control the tablet pressing mechanism to move in the vertical direction by telescopic control.

[0069] The tablet pressing mechanism comprises, from top to bottom, a first mounting base assembly 51, a first adapter assembly 52, a sensing assembly 53, a second adapter assembly 54, a second mounting base assembly 55, and a pressing head assembly;

[0070] In practice, the sensing component 53 is a pressure sensor.

[0071] The first mounting component 51 and the second mounting component 55 are respectively used to mount the sensing component 53 and the pressure head component;

[0072] The pressure head assembly consists of a replaceable first pressure head assembly 56 and a second pressure head assembly 57, which are used to press the catalyst in the tableting vessel 1 of different diameters, respectively.

[0073] The bottom plate 32 is provided with a slide rail assembly 61 at the top. The fixture mechanism 62 can slide in the horizontal direction through the slide rail assembly 61. The fixture mechanism 62 is used to support the tablet press 1 of different diameters.

[0074] In practice, the fixture mechanism 62 is the fixture base 91 of the tablet press 1.

[0075] Specifically, the press head assembly adopts a replaceable design, and with a sliding and switchable jig mechanism, it can quickly adapt to tableting vessels of different diameters, reducing adjustment time when changing samples and improving efficiency.

[0076] The grinding and screening module includes:

[0077] Vibration platform 71, located at the bottom of the grinding station, is used to vibrate horizontally to cause the catalyst powder of the second layer of filter screen to leak to the bottom layer filter screen 82.

[0078] The grinding mechanism, located on top of the vibration platform 71, is used to transmit the vibration amplitude of the vibration platform to the second-layer filter screen and obtain the remaining mass of the catalyst powder, in preparation for subsequent calculation of the remaining mass of the catalyst.

[0079] In practice, the remaining mass of the catalyst is catalyst powder that meets the target granulation particle size.

[0080] The grinding mechanism includes four vertical support columns 72 connected to the top of the vibration platform 71, and the vibration platform 71 transmits the vibration amplitude to the second-layer filter screen through the support columns 72;

[0081] The support column 72 is fixedly and penetratingly connected to three layers of inspection sieve trays 73 from top to bottom. The inspection sieve tray 73 is a square sheet structure with a circular through hole in the center.

[0082] A filter screen support 74 is provided above the three-layer test sieve tray 73, which is used to support the three-layer filter screen. The main body of the filter screen support 74 is circular, and a cuboid protrusion is provided on one side of the filter screen support 74 in the horizontal direction.

[0083] The three-layer filter is cup-shaped and includes a top filter 81, a middle filter 82, and a bottom filter 82. In practice, the top filter 81 has a mesh size of 300 micrometers, the middle filter 82 has a mesh size of 160 micrometers, and the bottom filter 82 has a mesh size of 160 micrometers.

[0084] Specifically, the structure of the support pillars and the inspection sieve tray ensures that vibration energy is efficiently and evenly transmitted to each layer of the filter screen, preventing energy attenuation from reducing the screening efficiency of the lower layers. The raised design of the filter screen support facilitates gripping and placement by the robotic arm. This invention processes powdered catalyst raw materials into granular catalysts with uniform particle size and suitable strength through specific processes and equipment to meet the performance requirements of catalysts in different industrial production processes, thereby improving the activity, selectivity, and stability of the catalyst.

[0085] Working process: The robotic arm pours the catalyst powder into the tableting vessel. According to the characteristics of the catalyst, the pressure of the tableting device is set to 0.1-5 MPa through the software. The tableting machine applies the set pressure to the catalyst in the tableting vessel containing the catalyst. After a period of time (the time is set according to the characteristics of the catalyst), the catalyst is pressed into a tablet with a certain strength.

[0086] This invention uses a robotic arm to move catalyst powder into a tableting device for tableting. The entire tableting process is automatically controlled, which increases the precision and automation of the catalyst granulation device.

[0087] The robotic arm picks up the tableting dish, places it on a balance to weigh it, records the total mass of the catalyst, and then pours the tableted catalyst onto a filter screen. The robotic arm picks up the grinding head and grinds the catalyst tablets on the filter screen, so that the catalyst passes through a coarse-pore filter screen and leaks to a second filter screen (the second filter screen is the filter screen with the target granulation particle size). The vibration of the vibration platform 71 in the horizontal direction causes the catalyst powder of the second filter screen to leak to the bottom filter screen 82.

[0088] This device uses a robotic arm combined with three layers of filters to grind the prepared catalyst tablets. After grinding, the catalyst powder in the second layer is sieved by the horizontal vibration of the vibration platform. The catalyst powder that leaks to the bottom filter is weighed by the robotic arm to calculate the catalyst forming rate.

[0089] The robotic arm picks up the bottom filter screen 82, weighs the remaining mass of the catalyst, and calculates whether the catalyst granulation rate is greater than the user's expected granulation rate through software. If it is less than the user's expected granulation rate, the pressing and grinding operation is repeated until the catalyst granulation rate meets the user's expected granulation rate, thus completing the catalyst granulation process.

[0090] Catalyst formation rate = Remaining mass of catalyst ÷ Total mass of catalyst × 100%.

[0091] This quantitative, repeatable, and feedback-based process has completely transformed the traditional experience-based manual granulation method. It ensures highly consistent results across different batches and by different operators, with high repeatability and automatic judgment of whether the target is met. This avoids the uncertainty of repeated manual trials, thus achieving full automation and high efficiency in the granulation process.

[0092] The robotic arm picks up the devices that have come into contact with the catalyst, including the filter screen, grinding head, and tableting vessel 1, and cleans them one by one through the cleaning device. After cleaning, the devices are returned to their original positions to complete the entire catalyst granulation process.

[0093] The technical solution of this utility model has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.

[0094] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
