[0013] After the detection of the silicon nitride ceramic products is completed, the servo motor is started to drive the stirring plate to continuously rotate 360°, so that the stirring plate can push the detected silicon nitride ceramic products onto the arc-shaped filter screen in the cleaning bin, and then the stirring plate in the cleaning bin is driven by the servo motor to swing reciprocally to push the silicon nitride ceramic products reciprocally.

In the middle of the bottom end of the inner cavity of the detection box 1, a partition 11 is fixedly connected. The detection box 1 on both sides of the partition 11 is divided into a detection chamber 16 and a cleaning chamber 17. Arc-shaped filters 12 are installed in both the detection chamber 16 and the cleaning chamber 17. Between the two sides of the detection box 1 above the two arc-shaped filters 12, a driving roller 14 is rotatably connected. On the outer sides of the two driving rollers 14, stirring plates 18 are fixedly connected. At one end of the outer side of the detection box 1, two servo motors 13 are installed. The driving ends of the two servo motors 13 are respectively connected to the two driving rollers 14. On one side of the detection box 1, a discharge port 15 is obliquely opened; at one end of the detection box 1 close to the servo motor 13, a water pump 3 is installed. The water suction end of the water pump 3 is communicated with a water suction pipe 32, and the water suction pipe 32 is communicated with an external water source. The water outlet end of the water pump 3 is communicated with a water outlet pipe 31. Between the two sides of the inner cavity of the detection box 1, a conduit 33 is installed. At the bottom of the conduit 33, a plurality of spray holes 34 are equidistantly opened. The water outlet pipe 31 penetrates through the detection box 1 and is communicated with one end of the conduit 33. During operation, the silicon nitride ceramic products to be detected are placed in the arc-shaped filter 12 in the detection chamber 16, and then the servo motor 13 is started to drive the stirring plate 18 to swing reciprocally by plus or minus 45°, so as to push the silicon nitride ceramic products immersed in the detection liquid to swing left and right on the arc-shaped filter 12, so that the silicon nitride ceramic products are in full contact with the detection liquid, thereby increasing the reaction speed between the silicon nitride ceramic products and the solution, reducing the detection time, and multiple silicon nitride ceramic products can be placed in the arc-shaped filters 12 on both sides of the stirring plate 18, so that multiple silicon nitride ceramic products can be simultaneously subjected to corrosion resistance detection, thereby improving the efficiency of the corrosion resistance detection of the silicon nitride ceramic products. And the servo motor 13 is started to drive the stirring plate 18 to continuously rotate 360°, so that the stirring plate 18 can push the detected silicon nitride ceramic products onto the arc-shaped filter 12 in the cleaning chamber 17, and then the stirring plate 18 in the cleaning chamber 17 is driven by the servo motor 13 to swing reciprocally to push the silicon nitride ceramic products reciprocally, and then the water pump 3 is started to spray clean water through the spray holes 34 onto the silicon nitride ceramic products to wash the detection solution, and then the washed silicon nitride ceramic products are discharged through the discharge port 15 by the stirring plate 18, thereby avoiding the corrosion or even injury to personnel caused by the residual detection solution on the surface of the silicon nitride ceramic products after being taken by personnel.

[0020] Specifically, refer to Figure 2 and Figure 3 , between the two sides of the inner cavity of the cleaning chamber 17 on one side of the conduit 33, an air drying pipe 4 is installed.

The height of the retaining wall 21 is higher than the width of the discharge port 15. Through the arrangement of the receiving plate 2, it is convenient to receive the silicon nitride ceramic products discharged after detection and cleaning, which is convenient for personnel to take. At the same time, the retaining wall 21 is used to prevent the discharged silicon nitride ceramic products from rolling off the receiving plate 2 and being damaged.

[0022] It should be noted that referring to Figure 2 , the stirring plate 18 is arranged in contact with the surface of the arc-shaped filter screen 12, and the center of the arc-shaped filter screen 12 is on the same horizontal line as the center of the driving roller 14, which is used to ensure that the rotation of the driving roller 14 can always make the stirring plate 18 contact with the inner wall surface of the arc-shaped filter screen 12.
