Description

Technical Field

[0001] This invention relates to a laboratory sample crushing device and its usage method, and more particularly to a honeycomb catalyst crushing device and its usage method, belonging to the technical field of laboratory auxiliary device manufacturing and usage method. Background Technology

[0002] Three-way catalysts (TWCs) are core functional components of gasoline internal combustion engine exhaust aftertreatment systems. They typically use honeycomb cordierite ceramic or metal alloy materials as a carrier, and employ a special coating process to load precious metal active components such as platinum (Pt), palladium (Pd), and rhodium (Rh) to form a porous catalytic reaction unit, hence the name honeycomb catalyst. Within an operating temperature window of 200–600°C, this catalyst efficiently converts carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) in gasoline internal combustion engine exhaust into harmless carbon dioxide (CO2), water (H2O), and nitrogen (N2) through catalytic redox reactions. Because the cost of loading precious metals is high and directly determines the catalyst's catalytic efficiency and lifespan, precise detection of the precious metal content in honeycomb catalysts is necessary for production process control, supply chain quality inspection, and recycling value assessment. This is crucial for controlling production costs, optimizing formulations, ensuring product quality, and enhancing recycling value. This type of detection typically requires breaking the rigid porous honeycomb structure into a uniform powder sample (usually with a particle size <100µm) to meet the sample introduction requirements of detection instruments such as X-ray fluorescence spectrometry (XRF) and inductively coupled plasma mass spectrometry (ICP-MS), thereby completing the corresponding physicochemical detection.

[0003] Because honeycomb catalysts are very hard, with a Mohs hardness of 7 to 8, they are quite difficult to break. Furthermore, the breaking process must be carried out in a way that is pollution-free and loss-free. This means that the sample preparation process must avoid introducing external metals, such as iron and chromium, to prevent pollution. At the same time, it is also necessary to prevent precious metal particles from escaping during the breaking process, which could lead to inaccurate detection and loss of precious metals.

[0004] Currently, the industry generally uses the traditional manual crushing method. The process includes primary cutting, which involves manually cutting the honeycomb catalyst into small pieces of 5-10 mm³ using carbide blades. Then, the small pieces are repeatedly crushed by manual hammering. After sieving, particles that do not meet the size requirements are crushed again by impact until the sample becomes powdery particles that meet the testing requirements.

[0005] Clearly, this method has obvious shortcomings:

[0006] First, the sample preparation efficiency is low because this manual crushing method usually takes 20 to 30 minutes to process a single sample. It is not only time-consuming and labor-intensive, but also seriously affects the efficiency of testing, and has become a bottleneck for testing timeliness.

[0007] Secondly, the labor costs are high because the production of samples requires intensive manual operation by skilled technicians throughout the process, which not only takes up a lot of the technicians' working time, but also ties up their valuable work energy.

[0008] Secondly, there is a risk of precious metal leakage, because cutting, hammering and other processes in open environments can cause micro-powdered precious metals to escape with the airflow, resulting in the loss of precious metals, which in turn affects the accuracy of detection and causes economic losses.

[0009] In addition, there are safety hazards, because the flying hard debris and metal dust can not only cause injuries to operators, but also damage their respiratory system.

[0010] Although there are various general-purpose crushing equipment in existing technologies, such as jaw crushers and ball mills, these devices are usually designed for bulk minerals or inexpensive materials and cannot meet the crushing needs of high-value and hard honeycomb catalysts. Therefore, there is an urgent need to develop a specialized, closed, and moderately automated honeycomb catalyst crushing and sample preparation device to improve efficiency while ensuring low or even zero loss of precious metals, thus fundamentally solving the current industry pain points. Summary of the Invention

[0011] To overcome the shortcomings of existing technologies, this invention first provides a honeycomb catalyst crushing device, and further provides a method for using the honeycomb catalyst crushing device, so as to improve working efficiency while ensuring low or even zero loss of precious metals, guaranteeing the accuracy and reliability of test data, reducing the workload of laboratory personnel, and protecting the physical and mental safety of laboratory personnel, thus fundamentally solving the current industry pain points. Therefore, the following technical solution is provided:

[0012] A honeycomb catalyst crushing device for crushing fragments of honeycomb catalyst into fine powder samples with a particle size suitable for physicochemical testing, wherein the honeycomb catalyst is a honeycomb-shaped hard material composed of metals such as platinum, palladium, and rhodium supported on a cordierite ceramic or alloy material carrier, comprising:

[0013] Outer barrel, mortar, barrel lid, impact hammer, connector, and impact generator, among which:

[0014] The mortar is placed inside the outer barrel to hold the honeycomb catalyst fragments to be crushed. The mortar has a screen on its peripheral wall. The screen is used to screen honeycomb catalyst particles that meet the particle size requirements for physicochemical testing after crushing and refining. There is a gap between the side of the mortar with the screen and the inner side wall of the outer barrel.

[0015] The lid covers the outer barrel, and the upper part of the lid has a through hole;

[0016] The impact hammer includes a hammer head and a hammer handle. The hammer head has a cross-section that is adapted to the mortar and larger than that of the hammer handle and can be placed inside the mortar. One end of the hammer handle is connected to the hammer head, and the other end extends to the outside of the mortar lid through the through hole.

[0017] The impact generator has an impact rod, which is connected to the hammer handle via a connector. When the impact generator generates a reciprocating impact motion, the impact rod drives the hammer head through the hammer handle to impact and crush the honeycomb catalyst fragments, so that they reach the particle size required for physicochemical testing.

[0018] Further:

[0019] The mortar also includes a top ring, a connecting rod, and an anvil. The outer circumference of the top ring can fit against the inner wall of the outer barrel. The connecting rod connects the top ring and the anvil to form a barrel-shaped frame structure. The inner side of the barrel-shaped frame structure is provided with a screen or is surrounded by a screen, while its outer side maintains a gap with the inner wall of the outer barrel.

[0020] Preferably, a positioning groove is provided on the outer periphery of the top ring, and a positioning protrusion strip that cooperates with the positioning groove is provided on the inner side wall of the outer barrel; the surface of the anvil is concave arc-shaped, and the bottom of the hammer head is an arc shape that can fit with the concave arc-shaped anvil surface.

[0021] Furthermore, the lid is a barrel-shaped component, the barrel wall of which can be fitted onto the outer side wall of the outer barrel, and at least three elastic hooks are evenly arranged on the outer side of the barrel wall, the elastic hooks being able to cooperate with and lock with corresponding latches arranged on the outer side wall of the outer barrel.

[0023] The barrel lid is also provided with a bolt cap on its through hole. The bolt cap is truncated cone-shaped and has a passage opening at its top.

[0024] The impact hammer is also provided with a plugging platform that can block the plug cap. The plugging platform is a truncated cone that can match the plug cap. The bottom of the plugging platform is connected to the hammer head and the top is connected to the hammer handle. The upper part of the plugging platform is also provided with a plugging hole.

[0025] When the plug hole protrudes from the passage of the plug cap along with the hammer handle, the plug platform closes the passage; when the plug pin is inserted into the plug hole and the elastic hook engages with the lock to lock, the impact hammer, the mortar, the outer barrel, and the barrel cover form a sealed crushing assembly.

[0026] Preferably, the hammer handle is also provided with anti-slip texture or protective sleeve, and the bucket lid is made of transparent material.

[0027] Further:

[0028] The connector includes a sleeve and a fixing pin. The sleeve has fixing holes at its upper and lower ends. The fixing hole at the upper end of the sleeve corresponds to the punch hole on the impact rod of the impact generator, and the fixing hole at the lower end of the sleeve corresponds to the hammer handle hole on the hammer handle of the impact hammer. After the fixing holes at the upper and lower ends of the sleeve are aligned with the punch hole on the impact rod and the hammer handle hole on the hammer handle, the fixing pin is inserted to complete the connection between the impact hammer and the impact generator.

[0029] Preferred:

[0030] The bottom of the outer barrel is also provided with a base, and the bottom of the base is also provided with a shock absorber, which is made of rubber.

[0031] Optionally, the impact generator is an electric hammer.

[0032] A method of using a honeycomb catalyst crushing device, wherein:

[0033] The honeycomb catalyst crushing device includes an outer barrel with a locking buckle on its outer wall, a mortar placed inside the outer barrel, a barrel cover that can be fitted onto the outer barrel, and an impact hammer placed inside the mortar and connected to an electric hammer as an impact generator via a connector, wherein:

[0034] The mortar includes a top ring and an anvil. The outer periphery of the top ring can fit against the inner side wall of the outer barrel. The mortar is also provided with a screen on its peripheral wall. The screen is used to screen honeycomb catalyst particle samples that meet the particle size requirements for physicochemical testing after crushing and refining. There is a gap between the screen and the inner side wall of the outer barrel.

[0035] The lid is a barrel-shaped component, and at least three elastic hooks are evenly arranged on the outer side of the barrel wall of the lid. The elastic hooks can cooperate with the locks provided on the outer wall of the outer barrel to lock it. The lid is also provided with a bolt cap at the top. The bolt cap is frustum-shaped and has a passage opening at the top of the bolt cap that connects to the mortar.

[0036] The impact hammer includes a hammer head, a hammer handle, and a plugging platform. The hammer head has a cross-section that is adapted to the mortar and larger than that of the hammer handle and can be placed into the mortar. The plugging platform is a frustum that can plug the plug cap. The bottom of the plugging platform is connected to the hammer head and the top is connected to the hammer handle. The upper part of the plugging platform is also provided with a plugging hole.

[0037] The electric hammer has an impact rod; the connector includes a sleeve and a fixing pin. The upper and lower ends of the sleeve are respectively provided with fixing holes. The fixing hole at the upper end of the sleeve corresponds to the punching hole on the impact rod of the electric hammer, and the fixing hole at the lower end of the sleeve corresponds to the hammer handle hole on the hammer handle of the impact hammer. After the fixing holes at the upper and lower ends of the sleeve are aligned with the punching hole on the impact rod and the hammer handle hole on the hammer handle, the fixing pin is inserted to complete the connection between the electric hammer and the impact hammer.

[0038] The specific steps for using the above-mentioned honeycomb catalyst crushing device include the following:

[0039] The honeycomb catalyst fragments to be crushed are placed in the mortar, and then the impact hammer is placed inside the mortar. The lid is placed over the upper part of the outer barrel, and the hammer handle of the impact hammer is passed through the passage of the lid. The elastic hook on the lid is then engaged with the lock on the outer barrel to lock it, thereby forming a sealable crushing assembly containing the honeycomb catalyst fragments to be crushed and consisting of the impact hammer, mortar, outer barrel and lid.

[0040] By connecting the impact rod of the electric hammer to the hammer handle of the impact hammer through the connector, the electric hammer can be turned on to impact and crush the honeycomb catalyst fragments. Then, the connection between the hammer handle and the impact rod is disconnected, the hammer handle is lifted, and a plug pin is inserted into the plug hole to lock the impact hammer and block the passage. The crushing assembly is shaken to screen the finely powdered honeycomb catalyst particles that meet the particle size required for physicochemical testing from the mortar to the outer barrel, thus completing the first crushing and screening of the honeycomb catalyst fragments.

[0041] The crushing assembly is then connected to the impact rod of the electric hammer using the connector. The electric hammer is then turned on to crush the honeycomb catalyst fragments again. Then, the connection between the hammer handle and the impact rod is unlocked and the honeycomb catalyst particles are screened a second time.

[0042] Repeat this process multiple times until the honeycomb catalyst fragments are completely crushed into a particle size sample that meets the requirements for physicochemical testing. Then, unlock the connection between the hammer handle and the impact rod of the electric hammer, as well as the connection between the bucket lid and the outer bucket. Remove the impact hammer and the mortar, and pour out the finely crushed honeycomb catalyst test sample that meets the specified particle size from the outer bucket, thus completing the use of the honeycomb catalyst crushing device. Compared with the prior art, the beneficial effects and advancements of the present invention are as follows:

[0043] This invention constructs a honeycomb catalyst crushing device using an outer barrel, a mortar, a lid, an impact hammer, a connector, and an impact generator. The mortar is located inside the outer barrel and is used to hold the honeycomb catalyst fragments to be crushed and sieved. A screen is provided on the peripheral wall of the mortar to screen out finely powdered honeycomb catalyst particles that meet the particle size requirements for physicochemical testing. The lid covers the outer barrel and has a through hole in its center. The impact hammer is connected to the impact generator through the connector. When the impact generator generates a reciprocating impact motion, it can drive the impact hammer to impact and crush the honeycomb catalyst fragments, making them into particle samples that meet the particle size requirements for physicochemical testing.

[0044] This invention overcomes the shortcomings of the prior art by integrating crushing and screening operations. It not only greatly improves the crushing and screening efficiency of honeycomb catalysts and reduces the labor intensity of testing personnel, but also effectively prevents sample loss, ensures accurate and reliable testing and full recovery of precious metals, and effectively prevents harm to the operator's body during operation.

[0045] The honeycomb catalyst crushing device provided by this invention is simple, practical, easy to operate, and easy to learn. Operators can complete the operation without special training and can ensure the consistency of samples. Compared with the prior art, it has substantial features and significant progress, and therefore has great promotion and application value. Attached Figure Description

[0065] It should also be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0066] The technical solution of the present invention will now be described in detail with reference to specific embodiments. Example 1

[0067] This embodiment provides a honeycomb catalyst crushing device for crushing and sieving honeycomb catalyst fragments to obtain particle samples of the required particle size for physicochemical testing. The honeycomb catalyst is a honeycomb-shaped hard material composed of precious metals such as platinum, palladium, and rhodium, supported by a cordierite ceramic or alloy material carrier.

[0068] like Figure 1 A three-dimensional structural schematic diagram of a honeycomb catalyst crushing device provided in this embodiment of the invention. Figure 2 This invention provides a schematic diagram of the three-dimensional structure of the mortar of a honeycomb catalyst crushing device, and... Figure 3 A three-dimensional schematic diagram of the exploded structure of a honeycomb catalyst crushing device provided in an embodiment of the present invention is shown below:

[0069] A honeycomb catalyst crushing device, comprising:

[0070] Outer bucket 10, mortar 20, bucket lid 30, impact hammer 40, connector 50, and impact generator 60, wherein:

[0071] The mortar 20 is set inside the outer barrel 10 to hold the honeycomb catalyst fragments (not shown in the figure) to be crushed and sieved. The mortar 20 has a screen 21 on its peripheral wall. The screen 21 is used to screen the honeycomb catalyst particle samples that meet the particle size required for physicochemical testing after crushing and refining. There is a gap between the side of the mortar 20 where the screen 21 is set and the inner side wall of the outer barrel 10.

[0072] The lid 30 covers the outer bucket 10, and the upper part of the lid 30 also has a through hole 31;

[0073] The impact hammer 40 includes a hammer head 41 and a hammer handle 42. The hammer head 41 has a cross-section that is adapted to the mortar 20 and larger than that of the hammer handle 42 and can be placed into the mortar 20. One end of the hammer handle 42 is connected to the hammer head 41, while the other end can extend to the outside of the lid 30 through the through hole 31.

[0074] The impact generator 60 has an impact rod 61, which is connected to the hammer handle 42 via a connector 50. When the impact generator 60 generates a reciprocating impact motion, the impact rod 61 drives the hammer head 41 through the hammer handle 42 to impact and crush the honeycomb catalyst fragments (not shown in the figure) to achieve the particle size required for physicochemical testing.

[0075] From the above description, it can be seen that:

[0076] This embodiment constructs a honeycomb catalyst crushing device using an outer barrel, a mortar, a lid, an impact hammer, a connector, and an impact generator. The mortar is located inside the outer barrel and is used to hold the honeycomb catalyst fragments to be crushed and sieved. A screen is provided on the peripheral wall of the mortar to screen out finely powdered honeycomb catalyst particles that meet the particle size requirements for physicochemical testing. The lid covers the outer barrel and has a through hole at its top. The impact hammer is connected to the impact generator through the connector. When the impact generator generates reciprocating impact motion, it can drive the impact hammer to impact and crush the honeycomb catalyst fragments, making them into particle samples that meet the particle size requirements for physicochemical testing.

[0077] The honeycomb catalyst crushing device provided in this embodiment integrates crushing and screening operations, which not only greatly improves the crushing and screening efficiency of honeycomb catalysts and reduces the labor intensity of testing personnel, but also effectively prevents sample loss, ensures accurate and reliable testing and full recovery of precious metals, and effectively prevents harm to the operator's body during operation. Thus, it effectively overcomes the shortcomings of the prior art and fundamentally solves a technical pain point in this field.

[0078] Furthermore, such as Figure 3 and Figure 4 A three-dimensional structural diagram of the mortar of another honeycomb catalyst crushing device provided in this embodiment of the invention is shown:

[0079] The mortar and pestle 20 also includes a top ring 22, a connecting rod 23 and an anvil 24. The outer periphery of the top ring 22 can fit against the inner wall of the outer barrel 10. The connecting rod 23 connects the top ring 22 and the anvil 24 to form a barrel-shaped frame structure. The inner side of the barrel-shaped frame structure is provided with a screen 21 or is surrounded by a screen 21, while its outer side maintains a gap with the inner wall of the outer barrel 10.

[0080] Preferably, a positioning groove 25 is provided on the outer periphery of the top ring 22, and a positioning protrusion 11 that cooperates with the positioning groove 25 is provided on the inner side wall of the outer barrel 10; the surface of the cutting board 24 is concave arc-shaped, and the bottom of the hammer head 41 is an arc shape that can fit with the concave arc-shaped cutting board surface.

[0081] It can be seen that:

[0082] The top ring can not only effectively seal the openings at the top of the mortar and outer barrel to prevent the honeycomb catalyst from escaping during crushing and screening, but also fix the gap between the mortar and outer barrel to ensure smooth hammer crushing and screening.

[0083] The top ring and the anvil are connected by a connecting rod to form a barrel-shaped frame structure, which not only improves the structural strength of the mortar, but also facilitates the setting and fixing of the screen. The area between the connecting rods can even be used as a grid, and the screen can be made into individual screens that can match the grid and have different mesh sizes. By embedding the screens of different mesh sizes into the grid, honeycomb catalyst samples of different particle sizes can be obtained.

[0084] The positioning groove and positioning protrusion obviously make it easier to place the mortar into the outer barrel;

[0085] Designing the surface of the cutting board as a concave arc allows the honeycomb catalyst fragments to gather better, enabling the arc-shaped hammer head, whose bottom fits the concave arc cutting board surface, to better exert its hammering effect, thus achieving a better hammering effect.

[0086] Furthermore, such as Figure 1 and 3 As shown:

[0087] The lid 30 is a barrel-shaped component. The barrel wall of the barrel-shaped component can be fitted onto the outer wall of the outer barrel 10. At least three elastic hooks 32 are evenly arranged on the outer side of the barrel wall. The elastic hooks 32 can cooperate with the corresponding latches 12 arranged on the outer wall of the outer barrel 10 to lock.

[0088] It can be seen that:

[0089] The lid can be locked in place by the combination of elastic hook and buckle to prevent it from falling off;

[0090] The barrel-shaped lid not only effectively covers the opening of the outer barrel, preventing the honeycomb catalyst from escaping during crushing and screening, but also allows the lid to slide moderately up and down along the outer wall of the outer barrel when the impact hammer moves up and down, while still effectively sealing the opening of the outer barrel, thus ensuring its sealing effect.

[0091] Preferred, such as Figure 3 As shown:

[0092] The barrel lid 30 is also provided with a bolt cap 33 on its through hole 31. The bolt cap 33 is frustum shaped and has a passage opening 34 on its top.

[0093] The impact hammer 40 is also provided with a plugging platform 43 that can plug the plug cap 33. The plugging platform 43 is a truncated cone that can match the plug cap 33. The bottom of the plugging platform 43 is connected to the hammer head 41 and the top is connected to the hammer handle 42. The upper part of the plugging platform 43 is also provided with a plugging hole 44.

[0094] This design is just like Figure 5 The three-dimensional structural diagram of the sealable crushing assembly, consisting of an impact hammer, a mortar, an outer barrel, and a lid, provided in this embodiment of the invention, is shown below:

[0095] On the one hand, when the plug hole 44 protrudes from the passage 34 of the plug cap 33 along with the hammer handle 42, the plug platform 43 can close the passage 34; on the other hand, when the plug pin 45 is inserted into the plug hole 44 and the elastic hook 32 is engaged with the lock 12 to lock, the impact hammer 40 can form a sealed crushing assembly 100 with the mortar (not shown in the figure), the outer barrel 10 and the barrel cover 30.

[0096] Preferred, such as Figure 3 and Figure 5 As shown, the hammer handle 42 is also provided with anti-slip texture 46 or protective sleeve (not shown in the figure), and the bucket lid 30 is made of transparent material.

[0097] Obviously, adding anti-slip textures or protective covers to the hammer handle makes it easier to grasp the crushing assembly for better shaking and screening; while using transparent material to make the barrel lid makes it easier to observe the condition of the honeycomb catalyst inside the mortar.

[0098] Furthermore, such as Figure 1 and Figure 3 As shown:

[0099] The connector 50 includes a sleeve 51 and a fixing pin 52. The upper and lower ends of the sleeve 51 are respectively provided with fixing holes 53. The fixing hole 53 at the upper end of the sleeve 51 corresponds to the punch hole 62 provided on the impact rod 61 of the impact generator 60, and the fixing hole 53 at the lower end of the sleeve 51 corresponds to the hammer handle hole 47 provided on the hammer handle 42 of the impact hammer 40. After the fixing holes 53 at the upper and lower ends of the sleeve 51 are aligned with the punch hole 62 on the impact rod 61 and the hammer handle hole 47 on the hammer handle 42 respectively, the fixing pin 52 is inserted to complete the connection between the impact hammer 40 and the impact generator 60.

[0100] Preferred, such as Figure 3 and Figure 5 As shown, a base 13 is also provided at the bottom of the outer barrel 10, and a shock absorber 14 is also provided at the bottom of the base 13. The shock absorber 14 is made of rubber.

[0101] Clearly, the outer barrel with a base is more stable, thus better able to withstand the impact and crushing of the honeycomb catalyst by the impact hammer; while the shock absorber at the bottom of the base can effectively alleviate vibration, reduce the disturbance to the environment and reduce noise when the honeycomb catalyst crushing device is working.

[0102] Optionally, the impact generator 60 is an electric hammer. Example 2

[0103] This embodiment provides a method for using a honeycomb catalyst crushing device. The method described in this embodiment involves using the honeycomb catalyst crushing device to crush and sieve the honeycomb catalyst fragments to make them into fine powder particles suitable for physicochemical testing. The honeycomb catalyst is a hard honeycomb structure composed of precious metals such as platinum, palladium, and rhodium, supported by a cordierite ceramic or alloy material carrier.

[0104] The usage method provided in this embodiment is mainly aimed at... Figure 3 and Figure 5 The honeycomb catalyst crushing device shown is as follows:

[0105] The aforementioned honeycomb catalyst crushing device includes an outer barrel 10 with a locking buckle 12 on its outer wall, a mortar 20 placed inside the outer barrel 10, a barrel cover 30 that can be fitted onto the outer barrel, and an impact hammer 40 placed inside the mortar 20 and connected to an electric hammer, which serves as an impact generator 60, via a connector 50; and

[0106] The mortar 20 includes a top ring 22 and an anvil 24. The outer periphery of the top ring 22 can fit against the inner side wall of the outer barrel 10, and a screen 21 is also provided on the periphery of the mortar 20. The screen 21 is used to screen honeycomb catalyst particle samples that meet the particle size required for physicochemical testing after crushing and refining. There is also a gap between the screen 21 and the inner side wall of the outer barrel 10.

[0107] The lid 30 is a barrel-shaped component, and at least three elastic hooks 31 are evenly provided on the outer side of the barrel wall of the lid 30. The elastic hooks 31 can cooperate with the locks 12 provided on the outer wall of the outer barrel 10 to lock. The lid 30 is also provided with a bolt cap 32 at the top. The bolt cap 32 is frustum-shaped and has a passage 33 at the top that connects to the mortar 20.

[0108] The impact hammer 40 includes a hammer head 41, a hammer handle 42, and a plugging platform 43. The hammer head 41 has a cross-section that is adapted to the mortar 20 and larger than that of the hammer handle 42 and can be placed into the mortar 20. The plugging platform 43 is a frustum that can plug the plug cap 32. The bottom of the plugging platform 43 is connected to the hammer head 41 and the top is connected to the hammer handle 42. A plugging hole 44 is also provided on the upper part of the plugging platform 43.

[0109] The electric hammer has an impact rod 61;

The crushing assembly 100 is shaken to screen the honeycomb catalyst particles that meet the particle size required for physicochemical testing from the mortar 20 to the outer barrel 10, thus completing the first crushing and screening of the honeycomb catalyst fragments.

[0114] Connect the crushing assembly 100 to the impact rod 61 of the electric hammer using connector 50, turn on the electric hammer to crush the honeycomb catalyst fragments (not shown in the figure) again, and then unlock the connection between the hammer handle 42 and the impact rod 61 to perform a second screening of the honeycomb catalyst particles.

[0115] Repeat this process multiple times until the honeycomb catalyst fragments are completely broken into a particle size sample that meets the requirements for physicochemical testing. Then, unlock the connection between the hammer handle 42 and the impact rod 61 of the electric hammer, as well as the connection between the bucket cover 30 and the outer bucket 10. Remove the impact hammer 40 and the mortar 20, and pour out the finely powdered honeycomb catalyst test sample that meets the required particle size from the outer bucket 10, thus completing the use of the honeycomb catalyst crushing device.
