Description

Technical Field

[0001] The utility model relates to the technical field of detection, and particularly to a catalyst quality detection mechanism. Background Art

[0002] The honeycomb catalyst structure is composed of a plurality of columnar porous components, which are penetrated in the length direction and sealed in the cross-section direction.

[0003] The production of honeycomb catalysts is to mix a powder mainly composed of TiO2 with a binder and the like to form a clay-like shape, extrude it into a honeycomb structure by a double-screw extruder, then perform a drying process through controllable water loss, conduct high-temperature calcination after drying, and finally complete the product production process by end-face modification and packaging of the honeycomb structure. In this manufacturing process, various defects such as cracks may occur in the honeycomb structure during extrusion, drying, and calcination. If cracks occur in the partitions of the honeycomb structure, etc., the strength of the honeycomb structure will be reduced, and the performance of the honeycomb structure cannot be fully exerted.

[0004] Quality control is necessary during the production process. According to the requirements of "GB / T 31587-2015 Honeycomb Flue Gas Denitrification Catalysts", qualified honeycomb structures are not allowed to have cracks that connect two channels. The simplest method for non-destructively inspecting cracks in such honeycomb structures is visual inspection. The outer wall and end face can be inspected visually, but it is difficult to inspect cracks in the channel walls inside the honeycomb structure visually. Especially with the increase in the number of channels per unit cross-section of the honeycomb structure and the thinning of the channel walls, visual inspection becomes more difficult.

[0005] Another non-destructive testing method is to detect internal defects of the honeycomb structure by ultrasonic pulse reflection method. However, this method requires manual positioning and detection of honeycomb structural parts, which is time-consuming and laborious, with low detection efficiency, and is not convenient for quickly inspecting and screening out defective unqualified honeycomb structural parts. In addition, quality inspections are required at multiple positions during the production process, and the easy operation and low cost of the equipment are also factors that need to be considered.

[0006] The information disclosed in this background art section is only intended to increase the understanding of the overall background of the present utility model, and should not be regarded as an admission or any form of implication that this information constitutes the prior art known to those of ordinary skill in the art.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0042] Embodiment 1:

[0043] As Figure 1 、 Figure 2 、 Figure 3 shown, the honeycomb catalyst quality detection mechanism includes a light-emitting mechanism 1 and an image acquisition mechanism 2. The light-emitting mechanism 1 includes a light source board 11, a plurality of controllable light sources 12, and a first positioning board 13. A plurality of controllable light sources 12 are evenly connected to the light source board 11. The image acquisition mechanism 2 includes a plurality of acquisition boards 21, a plurality of detection ends 22, and a second positioning board 23. A plurality of detection ends 22 are evenly connected to the acquisition boards 21. The first positioning board 13 and the second positioning board 23 are arranged at intervals. The first positioning board 13 includes a plurality of first light holes, and one side of the first positioning board 13 is connected to the light source board 11. The second positioning board 23 includes a plurality of second light holes, and one side of the second positioning board 23 is connected to the acquisition board 21. The positions of the controllable light sources 12, the positions of the first light holes, the detection ends 22, and the positions of the second light holes correspond one by one.

[0044] In this embodiment, the outer dimensions of the light-emitting mechanism 1 and the image acquisition mechanism 2 match the cross-sectional dimensions of the honeycomb catalyst 3.

[0045] Specifically, as Figure 4 、 Figure 6 shown, the light source board 11 includes a plurality of light source mounting holes, and the controllable light sources 12 can be detachably connected to the light source mounting holes. The acquisition board 21 includes a plurality of detection mounting holes, and the detection ends 22 can be detachably connected to the detection mounting holes. Specifically, the controllable light sources 12 can be threadedly connected into the light source mounting holes, and the detection ends 22 can be threadedly connected into the detection mounting holes. The detachable connection of the controllable light sources 12 to the light source mounting holes and the detachable connection of the detection ends to the detection mounting holes can both be adjusted adaptively according to the number of holes of the honeycomb catalyst, with flexible use and a wide range of applications.

[0046] The first positioning plate 13 is connected to the light source plate 11 by means of adhesion, snap connection or bolt connection, and the second positioning plate 23 is connected to the acquisition plate 21 by means of adhesion, snap connection or bolt connection. Among them, both the first positioning plate 13 and the second positioning plate 23 are made of soft materials and light-blocking materials. In this embodiment, rubber can be used. At this time, the first positioning plate 13 can be connected to the light source plate 11 by bolts. Similarly, the second positioning plate 23 can be connected to the acquisition plate 21 by bolts. The first positioning plate 13 and the second positioning plate 23 can also be made of felt-like materials. At this time, the bonding method can be used. In this embodiment, the first positioning plate 13 and the second positioning plate 23 are made of soft materials and light-blocking materials. On the one hand, it can achieve the sealing of the honeycomb catalyst 3 with the first positioning plate 13 and the second positioning plate 23 to prevent light leakage; on the other hand, it also prevents light from passing through other holes, so that the detection between each hole does not interfere with each other.

[0047] In this embodiment, the number of holes of the measured honeycomb catalyst is adjustable. For example, 9*9 holes, 11 holes * 11 holes, 13 holes * 13 holes, 15 holes * 15 holes, 16 holes * 16 holes, 18 holes * 18 holes, 20 holes * 20 holes, 22 holes * 22 holes, 25 holes * 25 holes, 30 holes * 30 holes, 25 holes * 35 holes, 40 holes * 40 holes, and so on. Similarly, both the first light hole and the second light hole are in the form of an N*M array, and both N and M are integers greater than 1-50.

[0048] As Figure 4 、 Figure 5 As shown in the figure, in this embodiment, the bottom of the light source plate 13 includes a first limiting plate, and the bottom of the acquisition plate 21 includes a second limiting plate. The first limiting plate and the second limiting plate together form a limiting support surface for supporting the honeycomb catalyst 3. Among them, the first limiting plate and the second limiting plate have the same structure. In this embodiment, the first limiting plate is used for illustration.

[0049] The first limiting plate includes a support bottom plate 14, a clamping plate 15, and a locking bolt 16. The support bottom plate 14 is connected to the bottom of the light source plate 13. A chute is provided on the top surface of the support bottom plate 14, and a slide rail is provided on the bottom of the clamping plate 15. The clamping plate 15 is slidably connected to the support bottom plate 14. When the clamping plate 15 clamps the honeycomb catalyst 3, the locking bolt 16 passes through the clamping plate 15 and abuts against the support bottom plate 14 to maintain the clamping state of the clamping plate 15.

[0050] The first limiting plate and the second limiting plate together form a limiting support surface for supporting the honeycomb catalyst, which can support and clamp the honeycomb catalyst to ensure stability during use.

[0051] The image acquisition mechanism 2 can adopt the existing technology and can display after sensing light.

[0052] When the utility model is in use, as Figure 1 , Figure 2 shown, both ends of the honeycomb catalyst 3 are limited on the first positioning plate 13 and the second positioning plate 23. During detection, the controllable light source 12 of the light-emitting mechanism 1 emits light in sequence, and the emitted light passes through the honeycomb catalyst and reaches the image acquisition mechanism 2 to form an optical path. When the image acquisition mechanism 2 detects light, the corresponding pore position is displayed in a high-brightness state. If the number of high-brightness pore regions is greater than or equal to 2, it can be determined that there are cracks in the pore wall of this pore channel, and then it can be determined that this honeycomb catalyst has quality defects and does not meet the quality standards. When it is determined to be unqualified, the detection is stopped. After all the controllable light sources 12 emit light and there are still no two or more pore regions showing high brightness, it is determined to be qualified and the detection is stopped. This embodiment has non-destructive detection, flexible operation and low detection cost.

[0053] Embodiment 2:

[0054] In this embodiment, on the basis of Embodiment 1, the honeycomb catalyst quality detection mechanism further includes a horizontal driving mechanism. When the light-emitting mechanism 1 is fixedly arranged, the side of the image acquisition mechanism 2 away from the light-emitting mechanism is connected to the horizontal driving mechanism; when the image acquisition mechanism 2 is fixedly arranged, the side of the light-emitting mechanism 1 away from the image acquisition mechanism is connected to the horizontal driving mechanism.

[0055] The horizontal driving mechanism can be one of a cylinder, a hydraulic cylinder, and a robotic arm. The horizontal driving mechanism can be used to adjust and adapt to honeycomb catalysts of different lengths, further improving the applicability of the detection mechanism.

[0056] For example, when detecting a 9*9 pore honeycomb catalyst. 9*9 controllable light sources 12 can be arranged on the light source plate 11, and the controllable light sources 12 are aligned with the pores of the honeycomb catalyst 3. The quasi-honeycomb catalyst 3 is limited by the first limiting plate, and the other end is limited by the second limiting plate for the honeycomb catalyst 3. The honeycomb catalyst 3 can also be gently pressed by the horizontal driving mechanism so that the pore wall of the honeycomb catalyst 3 is embedded on the first positioning plate 13 and the second positioning plate 23 to ensure that there is no light leakage. After the detection is started, the light source lights up hole by hole, and the image acquisition mechanism 2 collects the number of high-brightness regions. After all the light sources are lit, it stops automatically. When it is found that there are no two or more regions showing high brightness on the image acquisition mechanism 2, it is determined to be qualified. If it is found that two or more corresponding regions showing high brightness appear on the image acquisition mechanism 2, the detection is stopped and it is determined to be unqualified.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
