Abstract
Description
Technical Field
[0001] This utility model belongs to the field of detection equipment technology, specifically relating to a detection device for honeycomb carrier catalysts. Background Technology
[0002] A honeycomb-supported catalyst is a solid catalyst made by loading the active catalyst component and co-catalyst onto a honeycomb support material using physical or chemical methods, such as the honeycomb support for a three-way catalyst. For three-way catalysts, the honeycomb support is typically made of ceramic material. After the active catalyst component is coated (at the factory or after regeneration), the support needs to be tested, including pore blockage testing and weight testing.
[0003] In existing technologies, the hole plugging detection and weight detection steps are usually performed separately, requiring independent hole plugging detection equipment and weighing equipment, making the detection process relatively cumbersome. Hole plugging detection equipment typically uses a vision camera, and requires illumination (lightbox) on one side of the honeycomb carrier. The vision camera receives the transmitted light from the other side of the honeycomb carrier for detection. However, when the honeycomb carrier is placed on a mounting ring (a movable device located between the illumination and vision camera, with a light-transmitting hole in the center), only the outer edge of the mounting ring overlaps with the detection equipment. Its center deforms under pressure, causing the direction of the honeycomb holes to not align with the length direction from the vision camera to the illumination, thus failing to achieve optimal detection results and resulting in poor practicality. Utility Model Content

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0030] Please refer to the following: Figure 1 and Figure 2 The detection device for honeycomb carrier catalysts provided by this utility model will now be described.
[0031] To facilitate further understanding, several overlapping rings need to be set for different cellular carriers. The light-transmitting holes need to be consistent with the cellular carrier being tested. Only an annular plane for the outer edge of the light-transmitting hole is reserved for the outer edge of the cellular carrier to overlap. Therefore, for ease of manufacturing, they are usually formed by stamping and have a low thickness. The disadvantage of deformation under pressure is that the conventional approach is to thicken them. However, the specifications and dimensions of the cellular carriers being tested are different, especially those undergoing regeneration. Therefore, thickened overlapping rings will inevitably be inconvenient to handle and also inconvenient to stamping, which will increase costs.
[0032] Therefore, to solve the above problems, the provided detection device for honeycomb carrier catalyst includes a vertical housing 10, a support plate 20, a light box 30, a vision detection module 40, an auxiliary support structure 50, and a matching display control unit 60. The vertical housing 10 has an operating platform 11 at its top. The vertical housing 10 has a receiving cavity, and the operating platform 11 has a communication port communicating with the receiving cavity. The operating platform 11 has a weighing module 70. The support plate 20 is horizontally mounted on the operating platform 11, with its outer edge overlapping the edge of the communication port. The support plate 20 is used to support the honeycomb carrier to be tested, and the support plate 20 has light-transmitting holes corresponding to the honeycomb portion of the honeycomb carrier. The light box 30 is located at the bottom of the receiving cavity and is used to project light towards the communication port. The vision detection module 40 is fixed on the vertical housing 10 and has a detection section located above the operating platform 11 and corresponding to the light-transmitting holes. The auxiliary support structure 50 is disposed in the accommodating cavity and located at the communication port. It has multiple support parts located in the communication port, and each support part and the edge of the communication port together support the support plate 20.
[0033] The detection device for honeycomb carrier catalyst provided in this embodiment, compared with the prior art, features a detachable support plate 20 mounted on the operating platform 11 at the top of the vertical housing 10. Light emitted from the light box 30 at the bottom of the accommodating cavity is projected onto the honeycomb carrier through a light-transmitting hole on the support plate 20. A visual inspection module 40 then detects the photoelectric transmission through the honeycomb carrier, enabling hole blockage detection. A weighing module 70 is also installed on the vertical housing 10, integrating the weighing module 70 with the light transmission detection into a single device for easier operation. An auxiliary support structure 50 is installed in the accommodating cavity to further support the support plate 20 from the bottom. This prevents deformation of the support plate 20 due to pressure from the honeycomb carrier without increasing its thickness, thus ensuring the verticality of the honeycomb carrier and guaranteeing the detection effect.
[0034] It should be noted that the display control unit 60 may include a display control panel mounted on the operating platform 11 and an internal controller, which are electrically connected to the weighing module 70 and the vision inspection module 40, respectively, and are specifically capable of displaying the inspection results and the weighing structure. The weighing result can be a measuring scale with a weighing platform located above the operating panel; this technology is existing technology and will not be described in detail here.
[0035] In some embodiments, the support plate 20 may be adopted as follows: Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 The support plate 20 is a circular plate.
[0036] Specifically, the edge of the connecting opening has a first annular platform 12 for mounting the outer edge of the circular plate.
[0037] The first annular platform 12 is created by opening a groove on the operating platform 11. The diameter of the groove is larger than the diameter of the connecting opening, thus forming the first annular platform 12 between the two for the support plate 20 to be erected.
[0038] This structure ensures the accuracy of the circular plate placement, guaranteeing that the light-transmitting hole corresponds to the detection unit in the vision inspection module 40, thereby ensuring the best inspection results.
[0039] In some embodiments, the aforementioned light-transmitting hole can be as follows: Figure 1 The structure shown. See also Figure 1 The edge of the light-transmitting hole has a second annular platform 21 for the outer edge of the cellular carrier to be embedded.
[0040] The outer shell of the cellular carrier has a certain thickness. The second annular platform 21 can ensure the embedding of the cellular carrier, ensure that the cellular carrier corresponds to the detection part in the vision inspection module 40, and at the same time ensure that the light-transmitting hole covers the cellular part of the cellular carrier, thereby ensuring the detection effect.
[0041] In some embodiments, the auxiliary support structure 50 may adopt the following... Figure 2 and Figure 3 The structure shown. See also Figure 2 and Figure 3The auxiliary support structure 50 includes fixed rings 51, connecting shafts 52, and rotating arms 53. Two fixed rings 51 are provided, spaced apart vertically, with their axes aligned vertically and collinear with the central axis of the connecting opening. Both fixed rings 51 are located within the receiving cavity, with the upper fixed ring 51 fixedly connected to the top of the receiving cavity. Multiple connecting shafts 52 are provided, spaced annularly around the axes of the fixed rings 51, each vertically aligned, with both ends fixed to the two fixed rings 51. Multiple rotating arms 53 are provided, each corresponding to one of the connecting shafts 52. One end of each rotating arm 53 is rotatably mounted on the corresponding connecting shaft 52, while the other end extends into the connecting opening. Each extended end of the rotating arm 53 has a support block 54, the top of which is flush with the first annular platform 12, serving as a support component.
[0042] The arrangement of two fixing rings 51 and multiple connecting shafts 52 ensures that the formed frame structure has a certain strength, thereby guaranteeing the connection strength of each rotating arm 53 and facilitating the stability of the support. Simultaneously, the fixing rings 51 also...
[0043] The support portion provided at the end of the rotating arm 53 can work together with the first annular platform 12 to support the support plate 20, thereby effectively preventing the support plate 20 from deforming under the pressure of the honeycomb carrier. At the same time, there is no need to increase the thickness of the support plate 20, which makes it easy to pick up and put down while ensuring the detection effect.
[0044] Furthermore, for different cellular carriers, such as elliptical ones or those with varying diameters, the support plate 20 needs to be replaced. In this case, the position of each support block 54 can be adjusted by rotating the arm 53 to prevent the support block 54 from extending into the light-transmitting hole, while ensuring that the support block 54 supports each support plate 20. This adaptability makes it suitable for different support plates 20.
[0045] In some embodiments, the visual detection module 40 and the weighing module 70 described above can employ, for example... Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2 The visual inspection module 40 and the weighing module 70 are spaced apart. This layout can avoid interference and also facilitates inspection.
[0046] In some embodiments, the visual detection module 40 described above may employ, for example... Figure 1 and Figure 2 The structure shown. See also Figure 1 and Figure 2The vision inspection module 40 includes a hanger 41 and a vision camera 42. The hanger 41 is fixed on the vertical housing 10. The vision camera 42 is located above the operating platform 11 and fixed on the hanger 41; the vision camera 42 is the inspection unit. The hanger 41 ensures the stability of the vision camera 42. The vision camera 42 is existing technology, and its specific operating principle is well known to those skilled in the art and will not be described in detail here.
[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
