Description

Technical Field

[0001] The invention relates to the technical field of wear resistance testing of a material layer in a reactor shell, in particular to a testing device and method for efficiently testing the wear resistance of a material layer in a reactor shell. Background Art

[0002] The structure of the reactor produced in a workshop is as follows Figure 1~Figure 3 As shown, it includes an outer shell 1, a discharge hole 2 is opened at the bottom of the outer shell 1, four legs 3 are fixedly arranged on the bottom surface of the outer shell 1, and a layer of wear-resistant material layer 4 is coated on the inner wall of the outer shell 1, wherein the function of the material layer 4 is to prevent the granular material put into the outer shell 1 and doing centrifugal motion from wearing the outer shell 1 [because the granular material is stirred by the external stirring blades after being put into the outer shell 1, and under the stirring of the blades, the granular material will do centrifugal motion in the outer shell 1, and the granular material doing centrifugal motion will wear the inner wall of the outer shell 1], thereby preventing the granular material from wearing down the wall thickness of the outer shell 1, thereby playing a role in protecting the outer shell 1.

[0003] Since the material layer 4 coated inside the shell 1 is very important, a testing machine is used in the workshop to test the wear resistance of the material layer 4 of each reactor. The structure of the testing machine is as follows Figure 4~Figure 5 As shown, it includes a base 5, a sink groove 6 is opened on the top surface of the base 5, and four accommodating holes 7 are fixedly provided at the bottom of the sink groove 6; clamps are provided on both sides of the base 5, and the clamps include 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 by which the worker uses the testing machine to test the wear resistance of the material layer 4 of the reactor is: S1. A worker takes out a reactor and inserts a plug 10 into the discharge hole 2 of the reactor from bottom to top to block the discharge hole 2. Figure 6 As shown, the purpose of the plugging is to prevent the granular material put into the reactor shell 1 from leaking from the discharge hole 2; S2. The worker embeds the four legs 3 of the reactor into the four receiving holes 7 of the base 5 respectively, and embeds the bottom surface of the shell 1 of the reactor into the sink 6, so as to realize the positioning of the reactor. Figure 7 As shown; S3. The worker rotates the pressing blocks 9 of the two clamps downward so that the two pressing blocks 9 are pressed onto the top surface of the shell 1 of the reactor, thereby fixing the shell 1 of the reactor between the base 5 and the pressing blocks 9, thereby fixing the reactor. Figure 8 As shown; S4, the worker puts the weighed granular material into the shell 1 of the reactor, and then extends the stirring blade 12 of the stirrer 11 into the shell 1 from top to bottom, as shown in FIG. Fig. 9 As shown, the power part of the stirrer 11 is then turned on, and the power part drives the stirring blade 12 to rotate. The stirring blade 12 stirs the granular material in the shell 1 to make the granular material do centrifugal motion. The granular material doing centrifugal motion continuously wears the material layer 4 in the shell 1. The movement direction of the granular material is as shown in FIG. Fig. 9 As shown by the solid arrow in the middle; when the stirrer 11 stirs for the set time, the power part of the stirrer 11 is turned off and the stirring blade 12 stops rotating; S5. The worker rotates the pressing blocks 9 of the two clamps upward to separate the pressing blocks 9 from the shell 1 of the reactor, and then the worker removes the reactor from the base 5 and moves the base 5 to the surface inspection station; S6, the worker uses the CCD lens 13 to search the inner surface of the material layer 4, such as Fig.10 As shown, whether there are pits on the material layer 4 is observed. 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, and the worker determines that the reactor is a defective product, and re-coats a layer of material layer 4 on the defective 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, and the worker determines that the reactor is a qualified product, thereby realizing the wear resistance test of the material layer 4 of a reactor; S7. The worker repeats the operations of steps S1 to S6 to continuously perform wear resistance tests on the material layers 4 of multiple reactors.

[0005] However, although the method used in the workshop can test the wear resistance of the material layer 4 of the reactor, in actual operation, there are still the following technical defects: I. In step S1, the discharge hole 2 of the reactor needs to be manually blocked with a plug 10, and in step S3, the reactor needs to be manually fixed with two clamps' pressing blocks 9 before subsequent testing can be carried out. This undoubtedly increases the testing process, resulting in a long preparation time before the wear resistance of the material layer 4 of the reactor needs to be tested, which undoubtedly reduces the test efficiency of the wear resistance of the material layer 4 of the reactor.

[0006] II. Among them, in steps S4 to S6, the worker needs to take away the reactor first, then transfer the reactor to the surface inspection station, and then use the CCD lens 13 to check whether there are pits on the material layer 4 [the pits are caused by the wear of the granular material on the material layer], and then determine whether the wear resistance of the material layer 4 of the reactor meets the requirements; and the delay from taking out the reactor to transferring it to the surface inspection station reduces the test efficiency of the wear resistance of the material layer 4 of the reactor.

[0007] In addition, the surface area of ​​the material layer 4 is large, and the surface of the material layer 4 is manually illuminated area by area with the CCD lens 13, which takes a long time to completely illuminate the material layer 4, thereby further reducing the test efficiency of the wear resistance of the material layer 4 of the reactor.

[0008] Therefore, there is an urgent need for a testing device and method that can shorten the wear resistance testing time of the material layer of the reactor and greatly improve the wear resistance testing efficiency of the material layer of the reactor. Summary of the invention

A worker puts weighed granular material into the inner cavity of the rotating shell of the wear and detection mechanism from the strip groove of the rotating shell, and the granular material is deposited at the bottom of the inner cavity of the rotating shell, wherein the granular material serves as an abrasive; S2. The worker takes out a reactor, and respectively inserts the four legs of the reactor into the four receiving holes of the turntable of the positioning mechanism, and supports the bottom surface of the shell of the reactor in the sink, so as to realize the positioning of the reactor. At this time, the shell of the reactor is just coaxial with the hollow cylinder, and the left and right side walls of the shell are respectively located directly below the two L-shaped pressing plates; S3.

When the piston rods of the lifting cylinders are fully retracted, the two L-shaped pressure plates just press on the top surface of the outer shell of the reactor, thereby fixing the outer shell between the L-shaped pressure plates and the turntable. At this time, the outer cylindrical surface of the rotating shell contacts the material layer in the reactor, and at the same time, the two micro switches correspond to the material layer in the reactor; S4, wear the material layer in the reactor: the drive motor of the drive assembly of the wear and detection mechanism is started, 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 static outer shell, the rotating shell drives the granular material therein to perform centrifugal motion, the granular material performing centrifugal motion passes through the strip groove of the rotating shell and wears the material layer; when the granular material wears the material layer of the reactor to a set time, the controller controls the drive motor to turn off, at which time, the granular material performing centrifugal motion falls back to the bottom of the rotating shell; S5.

[0027] A method for efficiently testing the wear resistance of a material layer inside a reactor shell comprises the following steps: S1. A worker throws the weighed granular material into the inner cavity of the rotating shell 22 of the wear and detection mechanism 16 from the strip groove 23 of the rotating shell 22. The feeding direction is as follows: Fig. 22 As shown by the hollow arrow, the granular material is deposited at the bottom of the inner cavity of the rotating shell 22, wherein the granular material serves as an abrasive; S2, the worker takes out a Figure 1~Figure 3 In the reactor shown in FIG. 1 , the worker respectively inserts the four legs 3 of the reactor into the four receiving holes 7 of the turntable 42 of the positioning mechanism 15, and supports the bottom surface of the shell 1 of the reactor in the sink 6, thereby realizing the positioning of the reactor.

Figure 4~Figure 10 The test method shown does not require workers to plug the discharge hole 2 of the reactor with a plug 10, nor does it require workers to fix the reactor with two clamp blocks 9 before subsequent testing, thereby omitting the preparation process before the test, thereby shortening the subsequent test time, and greatly improving the test efficiency of the wear resistance of the material layer 4 of the reactor.

Fig.25 As shown by the solid arrow in the middle; when the granular material wears the material layer 4 of the reactor to a set time, the controller controls the drive motor 43 to turn off, at which time, the granular material doing centrifugal motion falls back to the bottom of the rotating shell 22; S5. Surface inspection of the material layer 4 in the reactor is performed, and the specific operation steps are as follows: S51, the piston rod of the pressing cylinder 37 of the wear control and detection mechanism 16 extends downward, the piston rod drives the pressing rod 38 to move downward, the pressing rod 38 drives the expansion block 39 to move downward relative to the stationary center rod 27, the expansion block 39 presses down the two slides 31, the slides 31 move outward along the guide rod 30, at the same time, the slide 31 drives the round rod 34 to move outward, the round rod 34 drives the micro switch 35 to move outward synchronously, when the piston rod of the pressing cylinder 37 is fully extended, the spring 36 of the micro switch 35 touches the material layer 4, as shown in FIG. Figure 26-27 As shown, at this time, the micro switch 35 sends an electrical signal to the controller, and the controller clears the received electrical signal; S52, the servo motor 41 of the positioning mechanism 15 is started, and the output shaft of the servo motor 41 drives the turntable 42 to rotate. The movement direction of the turntable 42 is as follows: Fig.28 As shown by the solid arrow in the middle, the turntable 42 drives the shell 1 of the reactor to rotate around its axis, and the shell 1 drives the material layer 4 to rotate synchronously; S53, control the piston rods of the two lifting 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 driving assembly, the vertical plate, the first horizontal plate 25, the second horizontal plate 26 and the two L-shaped pressing plates 19 to move upward synchronously, and then drives the rotating shell 22, the center rod 27, the expansion block 39, the flat plate 28 and the pressing rod 38 to move upward synchronously, so that the L-shaped pressing plate 19 is gradually separated from the shell 1, and at the same time, the rotating shell 22 is gradually withdrawn from the shell 1, and at the same time, the spring 36 of the micro switch 35 is attached to the material layer 4 and moves upward in a straight line. The movement direction of the micro switch 35 is as follows: Fig.28 As indicated by the hollow arrow; When the micro switch 35 is moving upward in a straight line, if the micro switch 35 sends an electrical signal to the controller again, it means that the spring piece 36 of the micro switch 35 is embedded in the pit of the material layer 4, which further indicates that there is a pit on the material layer 4 of the reactor, which further indicates that the wear resistance of the material layer 4 of the reactor does not meet the requirements, and the worker determines that the reactor is a defective product; If the micro switch 35 does not send an electrical signal to the controller after passing through the material layer 4 upward, it means that there is no pit on the material layer 4, and further indicates that the wear resistance of the material layer 4 of the reactor meets the requirements. The worker determines that the reactor is qualified, thereby realizing the wear resistance test of the material layer 4 of a reactor; S6. The worker repeats the operations of steps S2 to S5 to continuously perform wear resistance tests on the material layers 4 of multiple reactors.

[0029] Among them, it can be known from steps S4 to S5 that when the granular material in the rotating shell 22 that is doing centrifugal motion wears the material layer 4 of the reactor to the set time, it is only necessary to first control the piston rod of the downward pressure cylinder 37 of the wear and detection mechanism 16 to extend downward so that the spring piece 36 of the micro switch 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 reactor does rotational motion; then control the piston rod of the lifting cylinder 17 to retract upward, so that the spring piece 36 of the micro switch 35 does linear motion upward along the material layer 4, thereby finally realizing a comprehensive detection of the surface of the material layer 4 of the reactor. It can be seen from this that the present testing device can enable the reactor that has been worn by granular material to directly enter the surface detection station, compared with the Figure 4~Figure 10 The test method shown does not require workers to take out the reactor and then transfer it to the surface inspection station. There is no turnover in between, but online inspection is achieved, thereby shortening the test time of the wear resistance of the material layer 4 of the reactor, thereby greatly improving the test efficiency of the wear resistance of the material layer 4 of the reactor.

[0030] In addition, the material layer 4 of the reactor is rotating, and the spring 36 of the micro switch 35 is moving upward linearly relative to the material layer 4, so that all pits on the surface of the material layer 4 can be fully detected, and workers do not need to use the CCD lens 13 to search the surface of the material layer 4 area by area, thereby shortening the detection time of the surface of the material layer 4, and greatly improving the test efficiency of the wear resistance of the material layer 4 of the reactor.
