Description

Technical Field

[0001] This utility model belongs to the technical field of ceramic testing equipment, and in particular relates to a real-time detection device for ceramic whiteness during high-temperature calcination. Background Technology

[0002] In the high-temperature calcination process of ceramics, the existing methods for detecting the whiteness of ceramics are mostly offline, that is, sampling and testing after calcination. This method cannot obtain the changes in the whiteness of ceramics in real time during the calcination process, and cannot promptly detect and adjust factors that affect the whiteness during the calcination process (such as uneven temperature, abnormal atmosphere, etc.). This can easily lead to the ceramic products failing to meet the whiteness standards, resulting in production waste and increased costs.

[0003] For example, patent application number CN202010275495.4 describes a detection device for grading and coloring ceramic tiles, comprising a detection darkroom, an industrial camera disposed inside the detection darkroom, a detection frame disposed inside the detection darkroom, and a light source disposed inside the detection darkroom; wherein, the industrial camera includes a color difference detection camera, an edge detection camera, and a tile surface detection camera; the light source includes a first light source for working in conjunction with the color difference detection camera and the edge detection camera, and a second light source for working in conjunction with the tile surface detection camera, the first light source emitting white light and infrared light. However, the disadvantage of this technical solution is that sampling and testing are performed after the ceramic is calcined, and the changes in whiteness of the ceramic during the calcination process cannot be obtained in real time, which can easily lead to the ceramic products not meeting the whiteness standards, resulting in production waste and increased costs. Utility Model Content

[0004] The purpose of this invention is to provide a real-time detection device for ceramic whiteness during high-temperature calcination, in order to solve the problems in the prior art. The specific technical solution is as follows:

[0005] A real-time ceramic whiteness detection device during high-temperature calcination includes a base assembly, which is connected to a support and adjustment assembly via a bracket. A cooling and heat-reducing assembly is connected to the upper end of the support and adjustment assembly. A hyperspectral camera is held in the middle of the cooling and heat-reducing assembly. The base assembly is connected to the inlet of a shell-and-tube water chiller via a water pump, and the cooling and heat-reducing assembly is connected to the outlet of the shell-and-tube water chiller.

[0006] Furthermore, the base assembly includes a base with a hollow interior. An inlet pipe is connected to the upper end of the base, and an outlet pipe is provided on the side of the base. Both the outlet pipe and the inlet pipe are equipped with ball valves. A water circulation hose is provided on the side of the base, and the water circulation hose is connected to the inlet end of the shell-and-tube water chiller through a water pump.

[0007] Furthermore, a turntable is rotatably connected to the upper end of the base, and the turntable is fixedly connected to the lower end of the bracket, while the upper end of the bracket is fixed to the lower end of the support adjustment assembly.

[0008] Furthermore, the support adjustment assembly includes a lower support plate, which is fixed to the upper end of the bracket. The lower support plate is fixedly connected to a cylinder, the cylinder output end is connected to a middle support plate, and the middle support plate is slidably connected to an upper support plate. The lower support plate, the middle support plate, and the upper support plate are arranged parallel to each other and at equal intervals.

[0009] Furthermore, the middle layer support plate has two rotating rods on its side, which are arranged in a cross pattern. The ends of the two rotating rods are respectively rotatably connected to rotating rod one and rotating rod three. Rotating rod one is rotatably connected to the lower layer support plate, and rotating rod three is rotatably connected to the upper layer support plate.

[0010] Furthermore, baffles are fixed on both sides of the upper support plate.

[0011] Furthermore, the upper support plate is rotatably connected to the lead screw, and a sliding plate is slidably connected to the upper support plate, with the lead screw threadedly connected to the sliding plate.

[0012] Furthermore, the slide plate is rotatably connected to the lead screw, a cooling component is slidably connected to the slide plate, and the lead screw is threadedly connected to the cooling component.

[0013] Furthermore, the cooling and heat dissipation component includes a support frame that slides on a slide plate. The support frame is connected to a lead screw by two threads. Two insertion pipes are fixed inside the support frame. The two insertion pipes are slidably connected to two inner tubes respectively. A spring is provided between the insertion pipes and the inner tubes. The two inner tubes are fixedly connected to two fin holders respectively. The hyperspectral camera is clamped between the two fin holders.

[0014] Furthermore, the base is connected to one end of the cooling hose, the other end of the cooling hose passes through two finned frames and is connected to the water outlet of the shell-and-tube water chiller, and the cooling hose between the two finned frames is hung in the curved frame set at the upper end of the support frame.

[0015] The advantages of this utility model are:

[0016] The hyperspectral camera is mounted outside the observation window of the high-temperature calcination chamber. It captures the reflectance spectrum of the ceramic surface inside the kiln and uploads the spectral data to the processor to calculate a whiteness value that meets the CIE whiteness standard or a specific industry standard. The support adjustment component can adjust the height and position of the hyperspectral camera, and the cooling component can cool the hyperspectral camera to prevent overheating and performance degradation, as well as to prevent the hyperspectral camera from being heated for a long time and shortening its service life. The hyperspectral camera can monitor the whiteness changes of ceramics in real time and continuously, providing strong technical support for quality control in the ceramic production process.

[0024] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Example 1

[0026] like Figures 1-5As shown, a real-time ceramic whiteness detection device during high-temperature calcination includes a base assembly, which is connected to a support adjustment assembly via a bracket 5. A cooling and heat-reducing assembly is connected to the upper end of the support adjustment assembly, and a hyperspectral camera 25 is held in the middle of the cooling and heat-reducing assembly. The base assembly is connected to the inlet of a shell-and-tube water chiller via a water pump, and the cooling and heat-reducing assembly is connected to the outlet of the shell-and-tube water chiller.

[0027] The working principle of the above technical solution is as follows: The hyperspectral camera 25 is mounted on the outside of the observation window of the high-temperature calcination chamber. The hyperspectral camera captures the reflection spectrum information of the ceramic surface in the kiln and uploads the spectral data to the processor to calculate the whiteness value that meets the CIE whiteness standard or a specific industry standard. The support adjustment component can adjust the height position of the hyperspectral camera 25, and the cooling component can cool down the hyperspectral camera 25 to prevent the hyperspectral camera 25 from overheating and degrading its performance, and also to prevent the hyperspectral camera 25 from being heated for a long time, which would shorten its service life.

[0028] The hyperspectral camera 25 enables real-time and continuous monitoring of changes in the whiteness of ceramics, providing strong technical support for quality control in the ceramic production process. Example 2

[0029] like Figures 1-5 As shown, the base assembly includes a base 1, which is hollow inside. A water inlet pipe 3 is connected to the upper end of the base 1, and a water outlet pipe 2 is provided on the side of the base 1. Both the water outlet pipe 2 and the water inlet pipe 3 are equipped with ball valves. A water circulation hose 24 is provided on the side of the base 1, and the water circulation hose 24 is connected to the water inlet of the shell-and-tube water chiller through a water pump.

[0030] The upper end of the base 1 is rotatably connected to a turntable 4, and the turntable 4 is fixedly connected to the lower end of the bracket 5. The upper end of the bracket 5 is fixed to the lower end of the support adjustment component.

[0031] The working principle of the above technical solution is as follows: The base 1 is hollow. Water is injected into the base 1 through the water inlet pipe 3. When the cooling component is working, the water in the base 1 is cooled by the shell and tube water chiller and then enters the cooling component to cool the hyperspectral camera 25. After the water is cooled, it flows back into the base 1. The water in the base 1 plays a role in circulating cooling and at the same time increases the weight of the base 1 to ensure the stability of the overall device.

[0032] When the cooling components are not working, the water in the base 1 is drained through the water outlet pipe 2 to reduce the weight of the base 1 and facilitate the transfer of the entire device. Example 3

[0033] like Figures 1-5As shown, the support adjustment assembly includes a lower support plate 7, which is fixed to the upper end of the bracket 5. The lower support plate 7 is fixedly connected to the cylinder 6. The output end of the cylinder 6 is connected to the middle support plate 8. The middle support plate 8 is slidably connected to the upper support plate 9. The lower support plate 7, the middle support plate 8, and the upper support plate 9 are arranged in parallel and at equal intervals.

[0034] The middle layer support plate 8 has two rotating rods 11 on its side. The two rotating rods 11 are arranged crosswise. The ends of the two rotating rods 11 are rotatably connected to rotating rod 10 and rotating rod 12 respectively. Rotating rod 10 is rotatably connected to the lower layer support plate 7, and rotating rod 12 is rotatably connected to the upper layer support plate 9.

[0035] Both sides of the upper support plate 9 are fixed with baffles 13;

[0036] The working principle of the above technical solution is as follows: When the cylinder 6 is started, the output end of the cylinder 6 drives the middle support plate 8 to move upward, which drives the rotating rod 10, rotating rod 21 and rotating rod 32 to rotate, which drives the upper support plate 9 to move upward. The distance that the upper support plate 9 moves upward is greater than the distance that the middle support plate 8 moves upward, so as to realize the long-distance up and down movement of the upper support plate 9, thereby driving the cooling and heat dissipation components and the hyperspectral camera 25 to move up and down over a long distance, so as to facilitate the adjustment of the hyperspectral camera 25 to a suitable position for ceramic monitoring.

[0037] The baffle 13 serves a protective function, preventing operators from accidentally touching the first rotating rod 10, the second rotating rod 11, and the third rotating rod 12. Example 4

[0038] like Figures 1-5 As shown, the upper support plate 9 is rotatably connected to the lead screw 14, and a sliding plate 15 is slidably connected to the upper support plate 9. The lead screw 14 is threadedly connected to the sliding plate 15.

[0039] The slide plate 15 is rotatably connected to the lead screw 16, and a cooling and heat-reducing component is slidably connected on the slide plate 15. The lead screw 16 is threadedly connected to the cooling and heat-reducing component.

[0040] The working principle of the above technical solution is as follows: Rotating the lead screw 14 causes the slide plate 15 to slide on the upper support plate 9, which in turn causes the cooling and heat-reducing components and the hyperspectral camera 25 to move to the left or right. Rotating the lead screw 16 causes the cooling and heat-reducing components to slide on the slide plate 15, which in turn causes the hyperspectral camera 25 to move forward or backward, thereby adjusting the hyperspectral camera 25 to a suitable position for ceramic monitoring. Example 5

[0041] like Figures 1-5As shown, the cooling and heat dissipation assembly includes a support frame 17, which slides on a slide plate 15. The support frame 17 is threadedly connected to a lead screw 16. Two insertion tubes 18 are fixed inside the support frame 17. The two insertion tubes 18 are slidably connected to two inner tubes 19 respectively. A spring 20 is provided between the insertion tubes 18 and the inner tubes 19. The two inner tubes 19 are fixedly connected to two fin holders 21 respectively. A hyperspectral camera 25 is clamped between the two fin holders 21.

[0042] The base 1 is connected to one end of the cooling hose 22, and the other end of the cooling hose 22 passes through two finned frames 21 and is connected to the water outlet of the shell-and-tube water chiller. The cooling hose 22 between the two finned frames 21 is hung in the curved frame 23 set at the upper end of the support frame 17.

[0043] The working principle of the above technical solution is as follows: the water pump is started, and the water in the base 1 is sent into the shell and tube water chiller through the water circulation hose 24. The shell and tube water chiller cools the water. The cooled water flows back into the base 1 through the cooling hose 22. The cooled water flows in the cooling hose 22 in the fin frame 21 and cools the hyperspectral camera 25.

[0044] When a larger hyperspectral camera 25 is clamped, the hyperspectral camera 25 squeezes the two fin holders 21 to move to both ends, causing the insertion tube 18 and the inner tube 19 to slide, causing the spring 20 to be compressed, and the cooling hose 22 between the two fin holders 21 to be stretched. The curved frame 23 prevents the cooling hose 22 between the two fin holders 21 from falling on the hyperspectral camera 25 and affecting the operation of the hyperspectral camera 25.

[0045] This device is compatible with the mounting, clamping, and cooling of different models of hyperspectral cameras 25, demonstrating strong adaptability.

[0046] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are protected by this utility model.
