Description

Technical Field

[0001] The present invention relates to the technical field of abrasion resistance testing of the material layer inside the outer shell of a reaction kettle, in particular to a testing device and method for efficiently testing the abrasion resistance of the material layer inside the outer shell of a reaction kettle. Background Art

[0002] The structure of the reaction kettle produced in a certain workshop is as Figures 1 to 3 shown. It includes an outer shell 1. A discharge hole 2 is provided at the bottom of the outer shell 1. Four legs 3 are also fixedly provided on the bottom surface of the outer shell 1. A material layer 4 with wear-resistant performance is coated on the inner wall of the outer shell 1. Among them, the function of this material layer 4 is to prevent the particulate material put into the outer shell 1 and making centrifugal motion from wearing the outer shell 1 [because after the particulate material is put into the outer shell 1, it will be agitated by the external stirring blades. Under the agitation of the blades, the particulate material will make centrifugal motion in the outer shell 1, and the particulate material making centrifugal motion wears the inner wall of the outer shell 1], thereby preventing the wall thickness of the outer shell 1 from being thinned by the particulate material and playing a role in protecting the outer shell 1.

[0003] Since the material layer 4 coated inside the outer shell 1 is very important, for this reason, a testing machine is used in the workshop to test the abrasion resistance of the material layer 4 of each reaction kettle. The structure of this testing machine is as Figures 4 to 5 shown. It includes a base 5. A sunk groove 6 is provided on the top surface of the base 5. Four receiving holes 7 are fixedly provided at the bottom of the sunk groove 6. Clamps are provided on both sides of the base 5. The clamp includes a threaded rod 8 fixedly provided on the top surface of the base 5 and a pressing block 9 threadedly connected to the upper end of the threaded rod 8.

[0004] The method for workers to use this testing machine to test the abrasion resistance of the material layer 4 of the reaction kettle is as follows:

[0005] S1. The worker takes out a reaction kettle and embeds a plug 10 into the discharge hole 2 of the reaction kettle from bottom to top to block the discharge hole 2, as Figure 6 shown. The purpose of blocking is to prevent the particulate material put into the outer shell 1 of the reaction kettle from leaking from the discharge hole 2;

[0006] S2. The worker respectively embeds the four legs 3 of the reaction kettle into the four receiving holes 7 of the base 5, and embeds the bottom surface of the outer shell 1 of the reaction kettle into the sunk groove 6, so as to realize the positioning of the reaction kettle, as Figure 7 shown;

[0007] S3. The worker rotates the pressing blocks 9 of the two clamps downward so that the two pressing blocks 9 are both pressed against the top surface of the outer shell 1 of the reaction kettle, thereby fixing the outer shell 1 of the reaction kettle between the base 5 and the pressing block 9, and further realizing the fixation of the reaction kettle, as Figure 8 shown;

[0008] S4. Workers put the weighed granular materials into the outer shell 1 of the reactor, and then insert the stirring blades 12 of the stirrer 11 into the outer shell 1 from top to bottom. As shown in Figure 9 the figure, then turn on the power part of the stirrer 11. The power part drives the stirring blades 12 to rotate. The stirring blades 12 agitate the granular materials in the outer shell 1, so that the granular materials do centrifugal motion. The granular materials doing centrifugal motion continuously wear the material layer 4 in the outer shell 1. The moving direction of the granular materials is as shown by the solid arrow in Figure 9 the figure. When the stirrer 11 has been stirring for the set time, turn off the power part of the stirrer 11, and the stirring blades 12 stop rotating;

[0009] S5. Workers rotate the pressing blocks 9 of the two jigs upward to separate the pressing blocks 9 from the outer shell 1 of the reactor. Then, the workers remove the reactor from the base 5 and transfer the base 5 to the surface inspection station;

[0010] S6. Workers use the CCD lens 13 to illuminate the inner surface of the material layer 4, as shown in Figure 10 the figure, to observe whether there are pits on the material layer 4. If there are pits on the material layer 4, it means that the wear resistance of the material layer 4 of the reactor does not meet the requirements. The workers determine that the reactor is a non-conforming product and re-coat a layer of material layer 4 on the non-conforming product. If there are no pits on the material layer 4, it means that the wear resistance of the material layer 4 of the reactor meets the requirements. The workers determine that the reactor is a conforming product, thus realizing the wear resistance test on the material layer 4 of a reactor;

[0011] S7. Workers repeat the operations in steps S1 to S6 in this way, and can continuously perform the wear resistance test on the material layer 4 of multiple reactors.

[0012] However, although the method used in the workshop can test the wear resistance of the material layer 4 of the reactor, there are still the following technical defects in actual operation:

[0013] I. Among them, in step S1, it is necessary to manually block the discharge hole 2 of the reactor with the plug 10. In step S3, it is necessary to manually fix the reactor with the pressing blocks 9 of the two jigs, and then the subsequent tests can be carried out. This undoubtedly increases the test process and causes a long preparation time to test the wear resistance of the material layer 4 of the reactor. This undoubtedly reduces the test efficiency of the wear resistance of the material layer 4 of the reactor.

[0014] II. Among them, in steps S4 to S6, the worker needs to first remove the reaction kettle, then transfer the reaction kettle to the surface detection station, and then check whether there are pits on the material layer 4 through the CCD lens 13 [the pits are generated by the abrasion of the granular material on the material layer], and then it can be judged whether the wear resistance of the material layer 4 of the reaction kettle meets the requirements; and the delay time from taking out the reaction kettle to transferring it to the surface detection station reduces the test efficiency of the wear resistance of the material layer 4 of the reaction kettle.

[0015] In addition, the surface area of the material layer 4 is large, and the worker uses the CCD lens 13 to search the surface of the material layer 4 area by area, which takes a long time to complete the search of the material layer 4, thus further reducing the test efficiency of the wear resistance of the material layer 4 of the reaction kettle.

[0016] Therefore, there is an urgent need for a test device and method that can shorten the test time of the wear resistance of the material layer of the reaction kettle and greatly improve the test efficiency of the wear resistance of the material layer of the reaction kettle. Summary of the Invention

[0017] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-efficiency test device and method for testing the wear resistance of the material layer in the outer shell of a reaction kettle, which can shorten the test time of the wear resistance of the material layer of the reaction kettle and greatly improve the test efficiency of the wear resistance of the material layer of the reaction kettle.

[0018] The purpose of the present invention is achieved through the following technical solutions: A high-efficiency test device for testing the wear resistance of the material layer in the outer shell of a reaction kettle, which includes a workbench, a positioning mechanism for positioning the reaction kettle is arranged on the workbench, and a wear and detection mechanism for fixing the reaction kettle, wearing the material layer in the reaction kettle, and detecting the surface of the material layer is arranged on the tabletop of the workbench;

[0019] The wear and detection mechanism includes lifting oil cylinders fixed on the tabletop of the workbench and located on the left and right sides of the positioning mechanism. A lifting plate is fixed between the acting ends of the piston rods of the two lifting oil cylinders. An L-shaped pressing plate located directly above the positioning mechanism is fixed on the bottom surface of the lifting plate;

[0020] A hollow cylinder is rotatably installed in the lifting plate. The upper end of the hollow cylinder is connected with a driving component for driving its rotation. A connecting plate is welded on the outer cylindrical surface of the lower end of the hollow cylinder. The other end of the connecting plate is fixed with a rotating shell for accommodating granular materials. A strip-shaped groove communicating with its inner cavity is opened on the outer wall of the rotating shell;

[0021] On the top surface of the lifting plate, a vertical plate is fixedly arranged. On the right end surface of the vertical plate, a first cross plate and a second cross plate are fixedly arranged. On the bottom surface of the first cross plate, a central rod axially penetrating downward through the hollow cylinder is fixedly arranged. At the bottom end of the central rod, a flat plate located below the rotating shell is fixedly arranged. On the top surface of the flat plate, fixing seats are fixedly arranged on its left and right sides. On the inner end surface of the fixing seat, a guiding rod is fixedly arranged. Sliding seats are slidably mounted on both guiding rods. A horizontal spring is sleeved on the guiding rod. The left and right ends of the horizontal spring are respectively fixedly arranged on the fixing seat and the sliding seat. A wedge surface is formed on the top of the sliding seat. On the outer end surfaces of both sliding seats, a round rod is fixedly arranged. At the other end of the round rod, a micro switch is fixedly arranged. The elastic piece of the micro switch faces outward;

[0022] On the top surface of the second cross plate, a downward pressing oil cylinder is fixedly arranged. The piston rod of the downward pressing oil cylinder penetrates downward through the second cross plate, and the extending end is connected with a pressing rod. The pressing rod penetrates downward through the hollow cylinder, and the extending end is fixedly arranged with an expansion block. The expansion block is sleeved on the outside of the central rod. Inclined surfaces are formed on both the left and right sides of the expansion block. The two inclined surfaces of the expansion block are respectively in contact with the wedge surfaces of the two sliding seats.

[0023] The positioning mechanism includes a servo motor fixedly arranged on the bottom surface of the workbench. The output shaft of the servo motor penetrates upward through the workbench, and the extending end is fixedly arranged with a turntable. A sunken groove is formed on the top surface of the turntable. Four accommodating holes are fixedly arranged at the bottom of the sunken groove; The sunken groove is matched with the outer contour of the bottom of the shell of the reaction kettle, and the sunken groove is coaxially arranged with the hollow cylinder.

[0024] On the bottom surface of the lifting plate, two L-shaped pressing plates are fixedly arranged. The two L-shaped pressing plates are respectively located on the left and right sides of the hollow cylinder.

[0025] Two connecting plates are welded on the outer cylindrical surface of the hollow cylinder. The rotating shell is fixedly arranged between the two connecting plates.

[0026] The driving assembly includes a driving motor fixedly arranged on the top surface of the lifting plate and a driven gear fixedly arranged on the outer cylindrical surface of the hollow cylinder. The output shaft of the driving motor is connected with a driving gear. The driving gear is meshed with the driven gear.

[0027] A central hole is formed in the expansion block. The expansion block is sleeved on the central rod through the central hole.

[0028] The two micro switches are symmetrically arranged about the central rod on the left and right.

[0029] The testing device further includes a controller. The controller is electrically connected with the lifting oil cylinder, the downward pressing oil cylinder, the driving motor, the servo motor, and the micro switch through signal lines.

[0030] A method for efficiently testing the wear resistance of the material layer inside the shell of a reaction kettle includes the following steps:

[0031] S1. Workers put the weighed granular materials into the inner cavity of the rotating shell of the wear and detection mechanism from the strip-shaped groove of the rotating shell. The granular materials are deposited at the bottom of the inner cavity of the rotating shell. Here, the granular materials serve as abrasives.

[0032] S2. Workers take out a reaction kettle. Workers respectively embed the four legs of the reaction kettle into the four receiving holes of the turntable of the positioning mechanism, and support the bottom surface of the outer shell of the reaction kettle in the sunken groove, so as to realize the positioning of the reaction kettle. At this time, the outer shell of the reaction kettle is just coaxial with the hollow cylinder, and the left and right side walls of the outer shell are respectively directly below the two L-shaped pressing plates.

[0033] S3. Control the piston rods of the two lifting oil cylinders of the wear and detection mechanism to retract downward. The piston rods drive the lifting plate to move downward. The lifting plate drives the hollow cylinder, the drive assembly, the vertical plate, the first cross plate, the second cross plate and the two L-shaped pressing plates to move downward synchronously, and then drives the rotating shell, the central rod, the expansion block, the flat plate and the pressing rod to move downward synchronously. When the piston rods of the lifting oil cylinders are completely retracted, the two L-shaped pressing plates just press on the top surface of the outer shell of the reaction kettle, so as to fix the outer shell between the L-shaped pressing plate and the turntable. At this time, the outer cylindrical surface of the rotating shell contacts the material layer in the reaction kettle. At the same time, the two micro switches correspond to the material layer in the reaction kettle respectively.

[0034] S4. Wear the material layer in the reaction kettle: Control the drive motor of the drive assembly of the wear and detection mechanism to start. The drive motor drives the driving gear to rotate. The driving gear drives the driven gear to rotate. The driven gear drives the hollow cylinder to rotate around its own axis. The hollow cylinder drives the connecting plate to rotate. The connecting plate drives the rotating shell to rotate relative to the stationary outer shell. The rotating shell drives the granular materials in it to do centrifugal motion. The granular materials doing centrifugal motion pass through the strip-shaped groove of the rotating shell to wear the material layer. When the granular materials wear the material layer of the reaction kettle to the set time, the controller controls the drive motor to turn off. At this time, the granular materials doing centrifugal motion fall back to the bottom of the rotating shell again.

[0035] S5. Perform surface detection on the material layer in the reaction kettle. The specific operation steps are as follows:

[0036] S51. Control the piston rod of the pressing oil cylinder of the wear and detection mechanism to extend downward. The piston rod drives the pressing rod to move downward. The pressing rod drives the expansion block to move downward relative to the stationary central rod. The expansion block presses the two sliding seats downward. The sliding seats move outward along the guide rod. At the same time, the sliding seats drive the round rod to move outward. The round rod drives the micro switch to move outward synchronously. When the piston rod of the pressing oil cylinder is completely extended, the elastic piece of the micro switch touches the material layer. At this time, the micro switch sends an electrical signal to the controller, and the controller clears the received electrical signal.

[0037] S52. Start the servo motor of the control positioning mechanism. The output shaft of the servo motor drives the turntable to rotate. The turntable drives the outer shell of the reactor to rotate around its axis, and the outer shell drives the material layer to rotate synchronously.

[0038] S53. Control the piston rods of the two lifting oil cylinders to extend upward. The piston rods drive the lifting plate to move upward. The lifting plate drives the hollow cylinder, the drive assembly, the vertical plate, the first cross plate, the second cross plate, and the two L-shaped pressing plates to move upward synchronously, and further drive the rotating shell, the central rod, the expansion block, the flat plate, and the pressing rod to move upward synchronously, so that the L-shaped pressing plates are gradually separated from the outer shell. At the same time, the rotating shell gradually exits from the outer shell. At the same time, the elastic piece of the microswitch moves upward in a straight line along the material layer.

[0039] When the microswitch is moving upward in a straight line, if the microswitch sends an electrical signal to the controller again, it means that the elastic piece of the microswitch is embedded in the pit of the material layer. Furthermore, it means that there are pits on the material layer of the reactor, and further means that the wear resistance of the material layer of the reactor does not meet the requirements. The worker determines that the reactor is a defective product.

[0040] If the microswitch does not send an electrical signal to the controller after passing through the material layer upward, it means that there are no pits on the material layer. Furthermore, it means that the wear resistance of the material layer of the reactor meets the requirements. The worker determines that the reactor is a qualified product, thus realizing the wear resistance test on the material layer of a reactor.

[0041] S6. The worker repeats the operations in steps S2 to S5 in this way, and can continuously perform the wear resistance test on the material layers of multiple reactors.

[0042] The present invention has the following advantages: shortening the wear resistance test time of the material layer of the reactor and greatly improving the wear resistance test efficiency of the material layer of the reactor. Description of the Drawings

[0075] The following further describes the present invention in conjunction with the attached drawings. The protection scope of the present invention is not limited to the following:

[0076] As Figures 11 to 21As shown in the figure, a testing device for efficiently testing the wear resistance of the material layer inside the outer shell of a reaction kettle, which includes a workbench 14. A positioning mechanism 15 for positioning the reaction kettle is arranged on the workbench 14. A wear and detection mechanism 16 for fixing the reaction kettle, wearing the material layer 4 inside the reaction kettle, and detecting the surface of the material layer 4 is arranged on the tabletop of the workbench 14. The wear and detection mechanism 16 includes lifting oil cylinders 17 fixed on the tabletop of the workbench 14 and located on the left and right sides of the positioning mechanism 15. A lifting plate 18 is fixed between the acting ends of the piston rods of the two lifting oil cylinders 17. An L-shaped pressing plate 19 located directly above the positioning mechanism 15 is fixed on the bottom surface of the lifting plate 18. Two L-shaped pressing plates 19 are fixed on the bottom surface of the lifting plate 18, and the two L-shaped pressing plates 19 are respectively located on the left and right sides of the hollow cylinder 20.

[0077] A hollow cylinder 20 is rotatably installed inside the lifting plate 18. The upper end of the hollow cylinder 20 is connected with a driving component for driving its rotation. A connecting plate 21 is welded on the outer cylindrical surface of the lower end of the hollow cylinder 20. The other end of the connecting plate 21 is fixed with a rotating shell 22 for accommodating granular materials. A strip-shaped groove 23 communicating with its inner cavity is opened on the outer wall of the rotating shell 22. Two connecting plates 21 are welded on the outer cylindrical surface of the hollow cylinder 20, and the rotating shell 22 is fixed between the two connecting plates 21. The driving component includes a driving motor 43 fixed on the top surface of the lifting plate 18 and a driven gear 44 fixed on the outer cylindrical surface of the hollow cylinder 20. A driving gear 45 is connected to the output shaft of the driving motor 43, and the driving gear 45 meshes with the driven gear 44.

[0078] A vertical plate 24 is fixed on the top surface of the lifting plate 18. A first horizontal plate 25 and a second horizontal plate 26 are fixed on the right end surface of the vertical plate 24. A central rod 27 axially penetrating downward through the hollow cylinder 20 is fixed on the bottom surface of the first horizontal plate 25. The bottom end of the central rod 27 is fixed with a flat plate 28 located below the rotating shell 22. Fixed seats 29 are fixed on the top surface of the flat plate 28 and located on its left and right sides. Guide rods 30 are fixed on the inner end surfaces of the fixed seats 29. Slide seats 31 are slidably installed on the two guide rods 30. A horizontal spring 32 is sleeved on the guide rods 30. The left and right ends of the horizontal spring 32 are respectively fixed on the fixed seat 29 and the slide seat 31. A wedge surface 33 is opened on the top of the slide seat 31. Round rods 34 are fixed on the outer end surfaces of the two slide seats 31. The other end of the round rod 34 is fixed with a microswitch 35. The elastic piece 36 of the microswitch 35 faces outward. The two microswitches 35 are symmetrically arranged about the central rod 27.

[0079] A pressing oil cylinder 37 is fixedly arranged on the top surface of the second transverse plate 26. The piston rod of the pressing oil cylinder 37 penetrates downward through the second transverse plate 26, and a pressing rod 38 is connected to the extending end. The pressing rod 38 penetrates downward through the hollow cylinder 20, and an expansion block 39 is fixedly arranged on the extending end. The expansion block 39 is sleeved outside the central rod 27. A central hole is formed in the expansion block 39, and the expansion block 39 is sleeved on the central rod 27 through the central hole. Inclined surfaces 40 are formed on both the left and right sides of the expansion block 39, and the two inclined surfaces 40 of the expansion block 39 are respectively in contact with the wedge-shaped surfaces 33 of the two sliding seats 31.

[0080] The positioning mechanism 15 includes a servo motor 41 fixedly arranged on the bottom surface of the workbench 14. The output shaft of the servo motor 41 penetrates upward through the workbench 14, and a turntable 42 is fixedly arranged on the extending end. A sunken groove 6 is formed on the top surface of the turntable 42, and four receiving holes 7 are fixedly arranged at the bottom of the sunken groove 6; the sunken groove 6 is matched with the outer contour of the bottom of the shell 1 of the reaction kettle, and the sunken groove 6 is coaxially arranged with the hollow cylinder 20.

[0081] The testing device further includes a controller, which is electrically connected to the lifting oil cylinder 17, the pressing oil cylinder 37, the driving motor 43, the servo motor 41, and the microswitch 35 through signal lines. Workers can control the piston rods of the lifting oil cylinder 17 and the pressing oil cylinder 37 to extend or retract downward through the controller, and can also control the start or stop of the driving motor 43 and the servo motor 41, thus facilitating the operation of the workers. At this time, when the elastic piece 36 of the microswitch 35 is pressed, the microswitch 35 will send an electrical signal to the controller.

[0082] A method for efficiently testing the wear resistance of the material layer inside the shell of a reaction kettle includes the following steps:

[0083] S1. Workers put the weighed granular materials into the inner cavity of the rotating shell 22 of the wear and detection mechanism 16 from the strip-shaped groove 23 of the rotating shell 22. The feeding direction is as shown by the hollow arrow in Figure 22 , and the granular materials are deposited at the bottom of the inner cavity of the rotating shell 22. Among them, the granular materials are used as abrasives.

[0084] S2. Workers take out a reaction kettle as shown in Figures 1 to 3 . Workers respectively embed the four legs 3 of the reaction kettle into the four receiving holes 7 of the turntable 42 of the positioning mechanism 15, and support the bottom surface of the shell 1 of the reaction kettle in the sunken groove 6, so as to realize the positioning of the reaction kettle. As shown in Figure 23 , at this time, the shell 1 of the reaction kettle is just coaxially arranged with the hollow cylinder 20, and the left and right side walls of the shell 1 are respectively located directly below the two L-shaped pressing plates 19.

[0085] S3. Control the piston rods of the two lifting cylinders 17 of the wear control and detection mechanism 16 to retract downward. The piston rods drive the lifting plate 18 to move downward. The lifting plate 18 drives the hollow cylinder 20, the drive assembly, the vertical plate, the first cross plate 25, the second cross plate 26 and the two L-shaped pressing plates 19 to move downward synchronously, thereby driving the rotating shell 22, the central rod 27, the expansion block 39, the flat plate 28 and the pressing rod 38 to move downward synchronously. When the piston rods of the lifting cylinders 17 are fully retracted, the two L-shaped pressing plates 19 just press on the top surface of the outer shell 1 of the reactor, so as to fix the outer shell 1 between the L-shaped pressing plates 19 and the turntable 42, as Figure 24 shown. At this time, the outer cylindrical surface of the rotating shell 22 is in contact with the material layer 4 inside the reactor. At the same time, both micro switches 35 correspond to the material layer 4 inside the reactor;

[0086] Among them, it can be seen from steps S1 to S3 that this test device only needs to control the downward retraction action of the piston rods of the lifting cylinders 17 to fix the outer shell 1 of the reactor and make the material layer 4 inside the reactor enter the test station. Compared with the Figures 4 to 10 test method shown, it is not necessary for workers to block the discharge hole 2 of the reactor with the plug 10, nor is it necessary for workers to fix the reactor with the pressing blocks 9 of the two jigs to carry out subsequent tests, thus omitting the preparation process before the test, and then shortening the subsequent test time, and then greatly improving the test efficiency of the wear resistance of the material layer 4 of the reactor.

[0087] S4. Wear the material layer 4 inside the reactor: Control the drive motor 43 of the drive assembly of the wear control and detection mechanism 16 to start. The drive motor 43 drives the driving gear 45 to rotate. The driving gear 45 drives the driven gear 44 to rotate. The driven gear 44 drives the hollow cylinder 20 to rotate around its own axis. The rotation direction of the hollow cylinder 20 is as shown by the Figure 25 hollow arrow in. The hollow cylinder 20 drives the connecting plate 21 to rotate. The connecting plate 21 drives the rotating shell 22 to rotate relative to the stationary outer shell 1. The rotating shell 22 drives the granular material inside it to do centrifugal motion. The granular material doing centrifugal motion passes through the strip-shaped groove 23 of the rotating shell 22 to wear the material layer 4. The moving direction of the granular material is as shown by the Figure 25 solid arrow in. When the granular material wears the material layer 4 of the reactor to the set time, the controller controls the drive motor 43 to turn off. At this time, the granular material doing centrifugal motion falls back to the bottom of the rotating shell 22 again;

[0088] S5. Perform surface detection on the material layer 4 inside the reactor. The specific operation steps are as follows:

[0089] S51. Control the piston rod of the downward pressure oil cylinder 37 of the wear control and detection mechanism 16 to extend downward. The piston rod drives the pressure rod 38 to move downward. The pressure rod 38 drives the expansion block 39 to move downward relative to the stationary central rod 27. The expansion block 39 presses down on the two sliding seats 31. The sliding seats 31 move outward along the guide rod 30. At the same time, the sliding seats 31 drive the round rod 34 to move outward, and the round rod 34 drives the microswitch 35 to move outward synchronously. After the piston rod of the downward pressure oil cylinder 37 is fully extended, the elastic piece 36 of the microswitch 35 touches the material layer 4, as Figures 26 to 27 shown. At this time, the microswitch 35 sends an electrical signal to the controller, and the controller clears the received electrical signal;

[0090] S52. Start the servo motor 41 of the positioning mechanism 15. The output shaft of the servo motor 41 drives the turntable 42 to rotate. The movement direction of the turntable 42 is as shown by the solid arrow in Figure 28 . The turntable 42 drives the outer shell 1 of the reactor to rotate around its axis, and the outer shell 1 drives the material layer 4 to rotate synchronously;

[0091] S53. Control the piston rods of the two lifting oil cylinders 17 to extend upward. The piston rods drive the lifting plate 18 to move upward. The lifting plate 18 drives the hollow cylinder 20, the drive assembly, the vertical plate, the first cross plate 25, the second cross plate 26 and the two L-shaped pressing plates 19 to move upward synchronously, and further drive the rotating shell 22, the central rod 27, the expansion block 39, the flat plate 28 and the pressure rod 38 to move upward synchronously, so that the L-shaped pressing plate 19 is gradually separated from the outer shell 1. At the same time, the rotating shell 22 gradually exits from the outer shell 1. At the same time, the elastic piece 36 of the microswitch 35 moves upward in a straight line along the material layer 4. The movement direction of the microswitch 35 is as shown by the hollow arrow in Figure 28 ;

[0092] When the microswitch 35 is moving upward in a straight line, if the microswitch 35 sends an electrical signal to the controller again, it means that the elastic piece 36 of the microswitch 35 is embedded in the pit of the material layer 4, which further means that there are pits on the material layer 4 of the reactor, and further means that the wear resistance of the material layer 4 of the reactor does not meet the requirements. The worker determines that the reactor is a defective product;

[0093] If the microswitch 35 does not send an electrical signal to the controller after passing through the material layer 4 upward, it means that there are no pits on the material layer 4, which further means that the wear resistance of the material layer 4 of the reactor meets the requirements. The worker determines that the reactor is a qualified product, thus realizing the wear resistance test on the material layer 4 of a reactor;

[0094] S6. The worker repeats the operations in steps S2 to S5 in this way, and can continuously perform the wear resistance test on the material layers 4 of multiple reactors.

[0095] Among them, it can be seen from steps S4 to S5 that when the granular material moving in a centrifugal motion inside the rotating shell 22 wears the material layer 4 of the reaction kettle to the set time, it is only necessary to first control the piston rod of the pressing oil cylinder 37 of the wear and detection mechanism 16 to extend downward so that the elastic piece 36 of the microswitch 35 touches the material layer 4; then control the servo motor 41 of the positioning mechanism 15 to start so that the material layer 4 in the reaction kettle makes a rotational motion; then control the piston rod of the lifting oil cylinder 17 to retract upward so that the elastic piece 36 of the microswitch 35 moves upward in a straight line along the material layer 4, thereby finally realizing a comprehensive detection of the surface of the material layer 4 of the reaction kettle. It can be seen from this that this testing device can directly move the reaction kettle worn by the granular material into the surface detection station. Compared with the testing method as Figures 4 to 10 shown, there is no need for workers to take out the reaction kettle and then transfer it to the surface detection station. There is no intermediate transfer, but on-line detection is realized, thus shortening the testing time for the wear resistance of the material layer 4 of the reaction kettle, and then greatly improving the testing efficiency of the wear resistance of the material layer 4 of the reaction kettle.

[0096] In addition, the material layer 4 of the reaction kettle makes a rotational motion, while the elastic piece 36 of the microswitch 35 makes an upward linear motion relative to the material layer 4, thereby comprehensively detecting all the pits existing on the surface of the material layer 4. There is no need for workers to use the CCD lens 13 to search one area after another on the surface of the material layer 4, thus shortening the detection time of the surface of the material layer 4, and then greatly improving the testing efficiency of the wear resistance of the material layer 4 of the reaction kettle.
