[0002] Ceramic coating is a technology that improves the performance of a substrate by forming a thin layer of ceramic material on the surface of the substrate. Ceramic coating can significantly improve the hardness, wear resistance, corrosion resistance, thermal conductivity and other properties of the substrate, and is therefore widely used in various industries and application fields.

[0033] The experimenter places the ceramic coating material 10 on the outer surface of the disk 8 so that it is flush with the outer surface of the disk 8. The retraction movement of the telescopic cylinder 13 drives the driving column 20 to move. The driving column 20 drives multiple T-shaped slide bars 18 to move closer to each other through the guide column 21 and the guide groove 22.

[0035] During use, the experimenter places the sand material of the required mesh size into the internal storage of the sand barrel 9, then opens the valve at the bottom thereof, and then connects the nozzle 23 to the external high-pressure air pump through the air pipe and the air pipe joint 41, and the rubber friction wheel 30 drives the second gear 28 to rotate, and drives the third gear 29 to rotate through the second gear 28, so that the third gear 29 drives the first pulley 34 to rotate, and the first pulley 34 drives the second pulley 35 to rotate through the belt 36, and the second pulley 35 drives the worm 38 to rotate, and the worm 38 drives the worm wheel 37 to rotate, and the worm wheel 37 drives the rotating block 17 to rotate, and the rotating block 17 drives the nozzle 23 to rotate, and the nozzle 23 can be rotated to the required angle through the scale mark 39 and the indicator arrow 19.

[0036] In this embodiment, a fixed block is fixedly installed on the upper surface of the base 1, and a screw rod 4 is rotatably installed between the column 2 and the fixed block. The screw rod 4 is arranged between two T-shaped slide rails 3. The screw rod 4 passes through the outer surface of the slide seat 5 and is threadedly connected with it. The end of the screw rod 4 away from the disc 8 passes through the outer surface of the fixed block and is fixedly installed with a first crank handle 6.

[0037] This device facilitates the quick fixation of the ceramic coating material 10; after the ceramic coating material 10 is fixed, the first crank handle 6 is manually rotated to drive the screw rod 4 to rotate, and the screw rod 4 drives the test box 7 to move closer to the ceramic coating material 10 through the slide seat 5 until the opening of the test box 7 is flush with the outer surface of the ceramic coating material 10, and the first crank handle 6 can be stopped. At this time, the rubber friction wheel 30 is against the outer surface of the ceramic coating material 10.

[0038] In this embodiment, a brush roller 24 is rotatably installed on the inner wall of the test box 7 near the opening, and the brush roller 24 is against the outer surface of the ceramic coating material 10. The top end of the brush roller 24 passes through the upper surface of the test box 7 and is fixedly installed with a third gear 29.

[0039] The brush roller 24 is driven to rotate by the third gear 29 so that the brush roller 24 cleans the surface of the ceramic coating material 10 impacted by the sand material, and brushes off the sand material adhered to the surface of the ceramic coating material 10, so as to facilitate the subsequent detection of the area impacted by the sand material.

[0040] The dust filter bag 27 is fixedly mounted on the inner wall of the air vent, and the dust filter bag 27 is arranged inside the filter cartridge 26. A rotating plate 31 is rotatably mounted on the upper surface of the test box 7. The rotating plate 31 is fixedly connected to the top of the dust filter bag 27 near one end of the filter cartridge 26. A driving slide groove 32 is penetrated on the outer surface of the other end of the rotating plate 31. A sliding column 33 is fixedly mounted on the upper surface of the rubber friction wheel 30. The sliding column 33 is slidably mounted on the inner wall of the driving slide groove 32. The sliding column 33 is arranged at the eccentric position of the rubber friction wheel 30. A discharge port 25 is penetrated on the outer surface of the test box 7 near the bottom end. A discharge port 25 is arranged on the inner wall of the discharge port 25. By opening the discharge valve, the used sand material can be discharged from the discharge port 25 after the test is completed.

[0041] The rotation of the rubber friction wheel 30 drives the sliding column 33 to move eccentrically, and the sliding column 33 drives the rotating plate 31 to swing back and forth through the driving slide groove 32. The rotating plate 31 drives the dust filter bag 27 to collide with the inner wall of the filter cylinder 26 back and forth. Through this device, the sand and dust on the inner wall of the dust filter bag 27 can be shaken off, so that the pores of the dust filter bag 27 are not blocked, ensuring that the nozzle 23 can spray sand at a stable pressure.

[0043] In this embodiment, the dust filter bag 27 is made of non-woven fabric material and has a certain flexibility to facilitate reciprocating motion.

[0044] In this embodiment, it should be noted that when the angle of the nozzle 23 changes, the duration of the sand spraying is the same, which is convenient for comparing the erosion resistance of the ceramic coating material 10 at different angles. When the angle of the nozzle 23 is rotated, the surface of the ceramic coating material 10 that has been tested will be completely rotated to the outside of the test box 7, avoiding subsequent tests from affecting the previous test results.

[0045] It should be noted that when the present invention is in use, the experimenter places the sand material of the required mesh size into the internal storage of the sand cylinder 9, then opens the valve at the bottom thereof, and then connects the nozzle 23 to the external high-pressure air pump through the air pipe and the air pipe joint 41; then the experimenter places the ceramic coating material 10 on the outer surface of the disc 8, so that it is flush with the outer surface of the disc 8, and drives the driving column 20 to move through the retraction movement of the telescopic cylinder 13. The driving column 20 drives the multiple T-shaped slide bars 18 to move closer to each other through the guide column 21 and the guide groove 22. The T-shaped slide bar 18 clamps the ceramic coating material 10 through the clamping plate 11. The device is convenient for quickly fixing the ceramic coating material 10; after the ceramic coating material 10 is fixed After the ceramic coating material 10 is formed, the first crank handle 6 is manually rotated to drive the screw rod 4 to rotate, and the screw rod 4 drives the test box 7 to move close to the ceramic coating material 10 through the slide seat 5 until the opening of the test box 7 is flush with the outer surface of the ceramic coating material 10, and the first crank handle 6 can be stopped. At this time, the rubber friction wheel 30 is against the outer surface of the ceramic coating material 10, and then the valve of the high-pressure air pump is opened to spray high-pressure gas with a fixed pressure. Through the setting of the internal flow channel of the nozzle 23, the high-pressure gas drives the sand material to be sprayed out from the nozzle 23, and the sprayed high-speed sand material will hit the surface of the ceramic coating material 10. After the required test time is reached, the valve of the high-pressure air pump is closed, and the flow channel is set. The device is convenient for testing the erosion resistance of the ceramic coating material 10; after testing the ceramic coating material 10 of an area, the second crank 12 is manually rotated to drive the first gear 15 to rotate, so that the first gear 15 drives the annular gear 14 to rotate, and the annular gear 14 drives the disc 8 to rotate through the rotating drum, and the disc 8 drives the ceramic coating material 10 to rotate, and the rotation of the ceramic coating material 10 causes the rubber friction wheel 30 that abuts against its outer surface to rotate, and the rubber friction wheel 30 drives the second gear 28 to rotate, and the third gear 29 is driven to rotate by the second gear 28, so that the third gear 29 drives the first pulley 34 to rotate, and the first pulley 34 drives the second pulley 35 to rotate through the belt 36. The second pulley 35 drives the worm 38 to rotate, the worm 38 drives the worm wheel 37 to rotate, the worm wheel 37 drives the rotating block 17 to rotate, the rotating block 17 drives the nozzle 23 to rotate, the nozzle 23 can be rotated to a desired angle through the scale mark 39 and the indicator arrow 19, and the spray angle of the nozzle 23 relative to the ceramic coating material 10 can be adjusted through this device, so as to facilitate the testing of the erosion resistance of the ceramic coating material 10 at different angles; at the same time, the brush roller 24 is driven to rotate through the third gear 29, so that the brush roller 24 cleans the surface of the ceramic coating material 10 impacted by the sand material, and brushes off the sand material bonded to the surface of the ceramic coating material 10, so as to facilitate the subsequent detection of the area impacted by the sand material;When the nozzle 23 sprays high-speed sand material, the pressure inside the test box 7 will rise. Through the setting of the dust filter bag 27, the sprayed sand material dust is filtered out by the dust filter bag 27. At the same time, excessive gas is discharged from the dust filter bag 27. When used for a long time, the pores on the inner wall of the dust filter bag 27 will be blocked by sand material dust, resulting in that the pressure inside the test box 7 is in a high pressure state when the sand material is blasted. At this time, the pressure difference between the nozzle 23 and the pressure inside the test box 7 is small, resulting in the sand material impacting the ceramic coating material 1. 0 becomes smaller, thereby affecting the accuracy of the erosion resistance test of the ceramic coating material 10, so that the sliding column 33 is driven to move eccentrically through the rotation of the rubber friction wheel 30, and the sliding column 33 drives the rotating plate 31 to swing back and forth through the driving slide 32, and the rotating plate 31 drives the dust filter bag 27 to collide with the inner wall of the filter cylinder 26 back and forth. Through this device, the sand and dust on the inner wall of the dust filter bag 27 can be shaken off, so that the pores of the dust filter bag 27 are not blocked, ensuring that the nozzle 23 can spray sand with a stable pressure. ;
