Reinforced regions and a non-reinforced region are distributed within the cross section of the honeycomb carrier; the reinforced regions are located at peripheral positions within the cross section of the honeycomb carrier; there are at least two reinforced regions; each reinforced region comprises a thickened region, and the wall thickness of cells in the thickened region is greater than that in the non-reinforced region. The present invention solves the problem that when a cylindrical straight-through honeycomb carrier is impacted by an external force, and when the external force propagates inside the carrier, particularly when the radial component of the external force passes through outwardly facing right-angle corners, the square cells may be deformed or even damaged. In addition, the present invention also solves the problem that internal thermal stress, generated when the carrier is heated too rapidly, may cause damage to cell walls.

Description

Cylindrical honeycomb support, catalyst Technical Field

[0001] This invention relates to the field of honeycomb ceramic carrier technology, specifically to a cylindrical honeycomb carrier and catalyst. Background Technology

[0002] In the existing technology, a type of through-cell carrier with a relatively wide range of applications is cylindrical. The cell shape of this cylindrical through-cell carrier is generally a square cross-section, and these square cells are arranged in a checkerboard pattern in the cylindrical through-cell carrier. However, in these square compartments, one of the outward-facing apex angles in a set of diagonals perpendicular or nearly perpendicular to the outer circumference of the cylindrical carrier has a significant impact on the outer wall of the carrier. When this impact is transmitted within the carrier, the force can be considered to consist of two components: a radial force pointing inward along the radius and a circumferential force along the cross-section. The radial force is often the stronger component. When this radial force passes through the apex angle, the right-angled apex angle, bearing the radial force, may cause deformation or even damage to the square compartment. Therefore, this right-angled apex angle becomes a weak point in the cylindrical through-type carrier with square compartments. This weakness is even more pronounced when the diagonal direction of the right-angled apex angle completely coincides with the radial direction of the cross-section. Thus, the weakest link effect reduces the overall strength and pressure-bearing capacity of the cylindrical through-type honeycomb carrier. In addition, the 45-degree angle crack on the cross-section of the honeycomb carrier, that is, the diagonal crack, is not only affected by external forces. When the self-heating rate is too fast, the stress of the expansion of the honeycomb carrier will also be loaded onto the partition wall of the compartment in the form of radial force.

[0003] Therefore, when a cylindrical straight-through cellular carrier is subjected to an external impact, the transmission of the external force within the carrier, especially the radial component of the external force when passing through the outward right-angled apex, may cause deformation or even damage to the square compartments. In addition, the internal expansion stress generated by the excessively rapid heating of the cellular carrier may affect the compartment walls and cause damage. These are all problems that urgently need to be solved in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a cylindrical honeycomb carrier and catalyst to solve the problem that when a cylindrical straight-through honeycomb carrier is subjected to an external impact, the external force is transmitted inside the carrier, especially when the radial component of the external force passes through the outward right-angled apex, which may cause deformation or even damage to the square compartment.

[0057] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. It should be understood that the specific embodiments described herein are only for illustration and explanation of the present invention and are not intended to limit the present invention.

[0058] It should be noted that, in this invention specification, "reinforced area" refers to the area for which the strength of the compartment has been enhanced, while "non-reinforced area" refers to the area for which the strength of the compartment has not been enhanced.

[0059] Furthermore, the "square compartment" in this invention specification specifically includes a compartment with a square cross-section, and also includes a compartment with a rectangular cross-section.

[0060] First aspect

[0061] Referring to Figures 1, 4, 7, 10, and 13, this invention provides a cylindrical honeycomb carrier, wherein reinforcing and non-reinforcing regions 3 are distributed within the cross-section of the honeycomb carrier; wherein the reinforcing regions are located at the outer periphery of the cross-section of the honeycomb carrier; the number of reinforcing regions is at least two; each reinforcing region includes a thickened region 1, the wall thickness of the compartments in the thickened region 1 being greater than the wall thickness of the compartments in the non-reinforcing region 3. It is worth noting that thickening the wall in easily cracked areas improves the strength of the square structure, helps reduce the influence of radial forces, and reduces deformation or even breakage of the square compartments.

[0062] As mentioned in the background section, in a square compartment, one of the outward-facing apex angles of a set of diagonals perpendicular or nearly perpendicular to the outer circumference of the cylindrical carrier has a force that, when impacted by an external force, can be considered as consisting of two components: a radial force pointing inward along the radius and a circumferential force along the cross-section. In most applications, the radial force is often the stronger component. When this radial force passes through the apex angle, the right-angled apex angle may deform or even break under its load. Therefore, this right-angled apex angle becomes a weak point in the cylindrical through-type carrier with a square compartment shape. The weakness is even more pronounced when the diagonal of the right-angled apex angle completely coincides with the radius of the cross-section. Thus, the weakest link effect reduces the overall strength and load-bearing capacity of the cylindrical through-type honeycomb carrier. Therefore, the present invention proposes the above-mentioned solution, which enhances the compressive strength and impact resistance of the partitions and compartments by setting up a reinforcing zone and increasing the thickness of the partition walls within the reinforcing zone. Furthermore, the 45-degree angle cracking on the cross-section of the honeycomb carrier, i.e., diagonal cracking, is not only affected by external forces. When the heating rate is too fast, the stress from the expansion of the honeycomb carrier is also loaded onto the partition walls of the compartments in the form of radial forces. The above-mentioned technical solution provided by the present invention can also solve the problem that "internal thermal stress generated by excessive heating rate can cause damage to the partition walls of the compartments."

[0063] It is worth noting that the thickened partition wall concept provided by this invention can be applied not only to scenarios with a cylindrical carrier and a square compartment, but also to other carriers designed with square or rectangular compartments but having other three-dimensional shapes. For example, it can be a honeycomb carrier with a prism or various polygonal prisms such as triangular, quadrangular, pentagonal, hexagonal, and octagonal prisms with an elliptical cross-section. This is because, when these honeycomb carriers are designed with square or rectangular compartments, the right-angled apex of the compartment facing away from the center of the carrier's cross-section and towards the outer surface of the carrier will directly bear the radial component of the external impact force, which has a relatively large force. In other words, the thickened compartment wall concept provided by this invention has good versatility.

[0064] In some embodiments of the present invention, the wall thickness of the compartments in the thickened region 1 is 1.5 to 2.8 times the wall thickness of the compartments in the non-reinforced region 3. Specifically, it can be any one of the following values, or any value within the range of any two values: 1.6 times, 1.7 times, 1.8 times, 1.9 times, 2 times, 2.1 times, 2.2 times, 2.3 times, 2.4 times, 2.5 times, 2.6 times, and 2.7 times. The value can be selected and adjusted according to the actual application scenario and design standards. Referring to Figures 1, 4, 7, 10, and 13, in some embodiments of the present invention, along the radial direction of the cross-section of the cellular carrier, from the center of the cross-section of the cellular carrier towards the outer peripheral surface of the cellular carrier, the wall thickness of the compartments in the thickened region 1 gradually increases. It is worth noting that, in these embodiments, the average wall thickness of the compartment in the thickened area 1 is 1.5 to 2.8 times the wall thickness of the compartment in the non-reinforced area 3. Specifically, it can be any one of the following values, or any value within the range of any two values: 1.6 times, 1.7 times, 1.8 times, 1.9 times, 2 times, 2.1 times, 2.2 times, 2.3 times, 2.4 times, 2.5 times, 2.6 times, and 2.7 times. It can be selected and adjusted according to the actual application scenario and design standards. Alternatively, in these embodiments, the minimum wall thickness of the compartment in the thickened area 1 is at least 1.5 times the wall thickness of the compartment in the non-reinforced area 3, and the maximum thickness is at most 2.8 times the wall thickness of the compartment in the non-reinforced area 3. It is worth noting that a thicker wall thickness leads to higher stress between the thickened area 1 and the non-reinforced area 3. When subjected to external force or internal stress generated by thermal expansion, the honeycomb ceramic is more likely to crack at the junction of the thickened area 1 and the non-reinforced area 3. On the other hand, a thinner wall thickness will result in insufficient support and thus be more prone to breakage.

[0065] Referring to Figures 1, 4, 7, 10, and 13, in some embodiments of the present invention, the at least two reinforcing regions are centrally symmetrical about the center of the honeycomb carrier. This makes mold making more convenient and allows for complete inclusion of the easily cracked areas.

[0066] In some embodiments of the present invention, the compartments of the thickened region 1 include square compartments, some of which are arranged in such a way that their diagonals coincide with the radial direction of the cellular carrier.

[0067] In some embodiments of the present invention, the partially square compartment is provided with diagonal walls, which are arranged along the radial direction. It is worth noting that the diagonal wall structure described above is equivalent to dividing a square compartment into two triangular compartments. Since triangles have better structural stability and pressure resistance, this solution can further improve the impact resistance and pressure resistance of the cellular carrier.

[0068] Referring to Figures 1, 4, 7, 10, and 13, in some embodiments of the present invention, the reinforcing region further includes an irregularly shaped compartment region 2; the cross-sectional shape of the compartments in the irregularly shaped compartment region 2 has a chamfer and / or an inward convex portion.

[0069] Referring to Figures 4-5, 7-8, 10-11, and 13-14, in some embodiments of the present invention, the shape of the inner protrusion is an inner convex right angle, an inner convex rounded corner, or an inner convex decorative corner, and the inner convex right angle, inner convex rounded corner, or inner convex decorative corner is configured to protrude inward relative to the interior of the compartment in which it is located.

[0070] Referring to Figures 10 to 15, in some embodiments of the present invention, the thickened area 1 surrounds the periphery of the irregularly shaped compartment area 2.

[0071] Referring to Figures 4 to 9, in some embodiments of the present invention, the irregularly shaped compartment area 2 surrounds the periphery of the thickened area 1.

[0072] In some embodiments of the present invention, the thickened region 1 and the irregularly shaped compartment region 2 are separated by the non-reinforced region 3.

[0073] Referring to Figures 4 and 7, in some embodiments of the present invention, the number of reinforcing regions is four. Each reinforcing region has a thickened region 1 and an irregularly shaped compartment region 2 surrounding the thickened region 1. Each thickened region 1 contains a partially square compartment, and each irregularly shaped compartment region 2 surrounds the corresponding thickened region 1. The presence of the irregularly shaped compartment regions provides a further transition. When the irregularly shaped transition region is between the thickened region and the ordinary compartment, it can buffer the stress between the two during thermal expansion, making the honeycomb ceramic structure more stable.

[0074] Referring to Figures 4 and 7, in some embodiments of the present invention, the cross-sectional shape of each reinforcing region is a fan-shaped ring, the central angle of which ranges from 50° to 80°, and the ratio of the radial dimension of the fan-shaped ring to the radius of the cross-section of the honeycomb carrier is (0.2 to 0.35):1. A smaller fan-shaped ring region, with controlled angle and radius, results in a lower change in the opening ratio of the honeycomb ceramic end face, thus minimizing the increase in back pressure.

[0075] Referring to Figures 4 and 7, in some embodiments of the present invention, the cross-sectional shape of each thickened region 1 is a fan-shaped ring, the central angle of which is in the range of 20° to 40°, and the ratio of the radial dimension of the fan-shaped ring to the radius of the cross-section of the cellular carrier is (0.05 to 0.15):1.

[0076] Referring to Figures 4 and 7, in some embodiments of the present invention, each reinforcing region is provided with a thickened region 1 and an irregularly shaped compartment region 2 surrounding the thickened region 1. The reinforcing region is radially symmetrical about the cross-section of the carrier, the thickened region is radially symmetrical about the cross-section of the carrier, and the irregularly shaped compartment region is radially symmetrical about the cross-section of the carrier.

[0077] Referring to Figures 4 and 7, in some embodiments of the present invention, the reinforcing region has a reference line P, which coincides with a diagonal of a plurality of square compartments and radially coincides with the cross-section of the carrier. The reinforcing region is symmetrical about the reference line P, the thickened region is symmetrical about the reference line P, and the irregularly shaped compartment region is symmetrical about the reference line P.

[0078] Referring to Figures 10 and 13, in some embodiments of the present invention, the number of reinforcing regions is four, each reinforcing region having one irregularly shaped compartment region 2 and a thickened region 1 surrounding the periphery of the irregularly shaped compartment region 2; each irregularly shaped compartment region 2 has the partial square compartment, and each thickened region 1 is respectively surrounding the periphery of the irregularly shaped compartment region 2 corresponding to it.

[0079] Referring to Figures 10 and 13, in some embodiments of the present invention, the cross-sectional shape of each reinforcing region is a fan-shaped ring with a central angle ranging from 50° to 80°. The ratio of the radial dimension of the fan-shaped ring to the radius of the cross-section of the cellular carrier is (0.2 to 0.35):1.

[0080] Referring to Figures 10 and 13, in some embodiments of the present invention, the cross-sectional shape of each of the irregularly shaped compartments 2 is a fan-shaped ring, the central angle of which is in the range of 20° to 40°, and the ratio of the radial dimension of the fan-shaped ring to the radius of the cross-section of the cellular carrier is (0.05 to 0.15):1.

[0081] Referring to Figures 10 and 13, in some embodiments of the present invention, each reinforcing region is provided with a thickened region and an irregularly shaped compartment region 2 surrounding the thickened region. The reinforcing region is radially symmetrical about the cross-section of the carrier, the thickened region is radially symmetrical about the cross-section of the carrier, and the irregularly shaped compartment region is radially symmetrical about the cross-section of the carrier.

[0082] Referring to Figures 10 and 13, in some embodiments of the present invention, the reinforcing region has a reference line P, which coincides with a diagonal of a plurality of square compartments and radially coincides with the cross-section of the carrier. The reinforcing region is symmetrical about the reference line P, the thickened region is symmetrical about the reference line P, and the irregularly shaped compartment region is symmetrical about the reference line P.

[0083] Referring to Figures 1 to 3, the present invention provides a honeycomb carrier with square compartments. The cross-section of the carrier is provided with a reinforcing area and a non-reinforcing area 3. The square compartments in the non-reinforcing area 3 can be regarded as conventional square compartments in the prior art, while the compartments in the reinforcing area adopt a wall thickness enhancement design. That is, the carrier provided in this embodiment is provided with a thickened area 1. The wall thickness of the compartments in the thickened area 1 is greater than the wall thickness of the compartments in the non-reinforcing area 3. The specific thickening multiple can be any value in the range of 1.5 to 2.8 times. The carrier provided in this embodiment has four thickened regions 1, which are centrally symmetrically distributed about the center of the cross-section of the cylindrical carrier and located in the outer periphery of the carrier's cross-section. Furthermore, these four thickened regions 1 encompass the "square compartments whose diagonal direction coincides with or nearly coincides with the radial direction of the carrier's cross-section." Because the compressive strength of compartments with this distribution is relatively weak, the carrier provided in this embodiment can enhance the compressive strength of these compartments, thereby improving the overall compressive strength of the carrier. It is worth mentioning that the concept of the reinforcing region provided in this invention can be viewed as "at least two 'reinforcing ribs' or 'strengthening ribs' are provided along the longitudinal direction of the cylindrical carrier" to "reinforce and strengthen" the weak pressure-bearing areas of the carrier. Further, the central angle of the fan-shaped annular thickened region 1 is 30°, and the ratio of the radial dimension of the fan-shaped annulus to the radius of the carrier's cross-section is 0.15:1; the mesh size of the compartments is 750 mesh.

[0084] Referring again to Figures 1 to 3, the present invention also provides a cellular carrier, which, based on the aforementioned design concept of only thickened region 1, further incorporates the concept of "gradual wall thickness design". That is, while setting thickened region 1, the wall thickness of the compartments in thickened region 1 gradually increases along the radial direction of the carrier cross-section, from the center of the carrier cross-section to the outer wall surface of the carrier. At this time, the average wall thickness in each thickened region 1 (the sum of the thicknesses of the thickest and thinnest parts of the wall in thickened region 1 divided by two) can be any value between 1.5 and 2.8 times the wall thickness of the compartments in the non-reinforced region 3. Of course, it can also be that the thickness of the thinnest part is at least 1.5 times the wall thickness of the compartments in the non-reinforced region 3, while the thickness of the thickest part is at most 2.8 times the wall thickness of the compartments in the non-reinforced region 3.

[0085] Referring to Figures 4 to 6, this invention provides a honeycomb carrier. The cross-section of this carrier contains two types of reinforcing regions: a thickened region 1 and an irregularly shaped compartment region 2. One set of diagonals within a compartment of the irregularly shaped compartment region 2 is chamfered, while another set of diagonals within the same compartment retains a right angle. This design comprises four thickened regions 1 and four irregularly shaped compartment regions 2, each surrounding a thickened region 1. This design effectively integrates two reinforcing concepts into a single honeycomb carrier, further enhancing its strength. Furthermore, the central angle of the fan-shaped annular thickened region 1 is 30°, and the ratio of the radial dimension of the fan-shaped annulus to the radius of the carrier's cross-section is 0.15:1; the mesh size of the compartments is 750 mesh.

[0086] Referring to Figures 7 to 9, this invention provides a honeycomb carrier. The cross-section of this carrier contains two types of reinforcing regions: a thickened region 1 and an irregularly shaped compartment region 2. In the irregularly shaped compartment region 2, one set of diagonals within a compartment has convex rounded corners, while the other set of diagonals within the same compartment retains a right angle. This design comprises four thickened regions 1 and four irregularly shaped compartment regions 2, each surrounding a thickened region 1. This design effectively integrates two reinforcing concepts into a single honeycomb carrier to further enhance its strength. Furthermore, the central angle of the fan-shaped annular thickened region 1 is 30°, and the ratio of the radial dimension of the fan-shaped annulus to the radius of the carrier's cross-section is 0.15:1; the mesh size of the compartments is 750 mesh.

[0087] Referring to Figures 10 to 12, this invention provides a honeycomb carrier. The cross-section of this carrier contains two types of reinforcing regions: a thickened region 1 and an irregularly shaped compartment region 2. In the irregularly shaped compartment region 2, one set of opposite corners within a compartment is chamfered, while another set of opposite corners within the same compartment retains a right angle. This design comprises four thickened regions 1 and four irregularly shaped compartment regions 2, with each thickened region 1 surrounding one irregularly shaped compartment region 2. This design effectively integrates two reinforcing concepts into a single honeycomb carrier to further enhance its strength. Furthermore, the central angle of the fan-shaped annular thickened region 1 is 30°, and the ratio of the radial dimension of the fan-shaped annulus to the radius of the carrier's cross-section is 0.15:1; the mesh size of the compartments is 750 mesh.

[0088] Referring to Figures 13 to 15, this invention provides a honeycomb carrier. The cross-section of this carrier contains two types of reinforcing regions: a thickened region 1 and an irregularly shaped compartment region 2. In the irregularly shaped compartment region 2, one set of diagonals within a compartment has convex rounded corners, while the other set of diagonals within the same compartment retains right angles. This design comprises four thickened regions 1 and four irregularly shaped compartment regions 2, with each thickened region 1 surrounding one irregularly shaped compartment region 2. This design effectively integrates two reinforcing concepts into a single honeycomb carrier to further enhance its strength. Furthermore, the central angle of the fan-shaped annular thickened region 1 is 30°, and the ratio of the radial dimension of the fan-shaped annulus to the radius of the carrier's cross-section is 0.15:1; the mesh size of the compartments is 750 mesh.

[0089] Referring to Figure 16, this invention illustrates a prior art honeycomb carrier, which is also cylindrical in shape and has square compartments arranged in a checkerboard pattern. However, the thickened region 1 of this carrier is located around the entire outer circumference of the carrier's cross-section, with the radial dimension of this annular region being 0.15:1 to the radius of the carrier's cross-section, and the compartment density having a mesh size of 750 mesh. In this prior art honeycomb carrier, there is no "thickness transition zone" between the thickened region 1 and the non-reinforcing region 3, resulting in abrupt changes in the stress on the compartment walls. Furthermore, the abrupt changes in wall thickness cause uneven extrusion speeds during processing, requiring multiple adjustments to the processing die to successfully extrude the entire carrier blank. Additionally, the thickened region 1 of this honeycomb carrier has a large area proportion, but the actual area requiring reinforcement is not that large, leading to a certain degree of material waste.

[0090] Referring to Figure 17, this invention illustrates a prior art honeycomb carrier, which is also cylindrical in shape and has square compartments arranged in a checkerboard pattern. However, the thickened area 1 of this carrier is a fan-shaped design, extending from the outer wall of the carrier to the center of the carrier's cross-section. The central angle of the fan-shaped area is 30°, and the mesh size of the compartments is 750 mesh. In this prior art honeycomb carrier, there is no "thickness transition zone" between the thickened area 1 and the non-reinforced area 3, resulting in abrupt changes in the stress on the compartments. Furthermore, the abrupt changes in wall thickness lead to uneven extrusion speeds during processing, making it impossible to adjust the extrusion speeds of the compartments in the thickened area 1 and the non-reinforced area 3 to be the same using conventional methods. In addition, compared to the honeycomb carrier provided by this invention shown in Figures 1 to 3, the area of ​​the thickened area 1 in this prior art honeycomb carrier is larger, but the actual area requiring reinforcement is not that large, resulting in a certain degree of material waste.

[0091] It is worth noting that the honeycomb carrier provided by the present invention can be composed of ceramic, metal or other materials, and there is no sole limitation on the material.

[0125] The yield in Table 1 below refers to the yield of the products of Examples 1 to 5 and Comparative Examples 1 to 2 under the same conditions of raw material ratio, extrusion pressure, extrusion speed, drying speed, sintering temperature and so on.

[0126] Table 1 Performance data of the cellular carrier obtained from each embodiment and comparative example.

[0127] As can be seen from the data listed in Table 1, compared with Examples 3 and 4, Examples 1 and 2 have a 50°C higher thermal shock resistance to products with chamfered walls; the A-axis compressive strength is increased by 1 MPa; the isostatic compressive strength is increased by 2 MPa; and the transition structure of the irregularly shaped compartment area is conducive to the uniform distribution of pressure of the molding clay on the mold, resulting in a yield rate of about 5%.

[0128] Example 5 uses a gradually thickened reinforced structure with no chamfered transition area, which reduces the thermal shock of the product. The uneven pressure distribution of the molding clay on the mold results in a yield that is about 7% lower than that of Examples 1 and 2.

[0129] Compared with Example 5, Comparative Example 1 lacked a gradual structure and exhibited more pronounced pressure unevenness, leading to a further decrease in yield.

[0130] Compared with Example 1, Comparative Example 2 has no gradual change in wall thickness and no transition region, and its thermal shock resistance, compressive strength of the A and B axes, and isostatic compressive strength are all significantly reduced.
