Description

Technical Field

[0001] The invention relates to the technical field of impact resistance testing of a material layer on a reactor end cover, in particular to a testing device and a testing method for the impact resistance of a material layer on a reactor end cover. Background Art

[0002] The function of the reactor is to provide a container for the reaction of granular materials and liquids. The structure of the reactor produced in a production workshop is as follows: Figure 1~Figure 2 As shown, the reactor includes a reactor body 1 and an end cover 2 fixed to the bottom of the reactor body 1, and a material layer 3 (the material layer 3 is also called a coating) is coated on the top surface of the end cover 2. The function of the material layer 3 is that when particulate materials are added into the reactor, the material layer 3 can withstand the impact force of the put particulate materials, thereby avoiding the end cover 2 from being deformed by the impact, thereby achieving the purpose of protecting the end cover 2 of the reactor.

[0003] When a batch of reactors are produced in the workshop, the workshop uses Figure 3 The testing machine shown is used to perform impact resistance test on the material layer 3 on each reactor end cover 2, and the unqualified products and qualified products sorted out in the test are transferred to the rework process and the packing process respectively. That is to say, after the test, the qualified products are sent to the customers, and the material layer in the unqualified products is repaired.

[0004] The testing machine includes a pad 4, two support seats 5 fixed on the top surface of the pad 4, and a gantry 6 fixed on the pad 4. A discharge bin 7 is fixed in the gantry 6. A solenoid valve 8 is connected to the bottom port of the discharge bin 7. The discharge bin 7 is filled with granular materials for impacting the material layer 3 on the end cover 2. Two clamping cylinders 9 are also fixed on the crossbeam of the gantry 6, which are respectively located on the left and right sides of the discharge bin 7. The working ends of the piston rods of the two clamping cylinders 9 both penetrate the crossbeam downward, and pressure heads 10 are fixed on the extended ends.

[0005] The method by which the worker uses the testing machine to test the impact resistance of the material layer on each reactor end cover 2 is:

[0006] S1. Use the granular material in the discharge bin 7 to impact the material layer 3 on the end cover 2 multiple times. The specific operation steps are as follows:

[0007] S11 The worker supports the end cover 2 of the reactor to be tested between two support seats 5, such as Figure 4 As shown, ensure that the middle of the end cover 2 of the reactor is just below the solenoid valve 8 of the discharge bin 7;

[0008] S12, control the two clamping oil cylinders 9 to extend downward, and the piston rod drives the pressure head 10 to move downward. When the piston rod of the clamping oil cylinder 9 is fully extended, the two pressure heads 10 press the left and right side walls of the reactor body 1 respectively. Figure 5 As shown, the reaction kettle is fixed, and then the end cover 2 is fixed;

[0009] S13, control the solenoid valve 8 to start, the granular material in the discharge bin 7 falls from the solenoid valve 8 under its own gravity, the fallen granular material enters the reactor body 1, and then hits the material layer 3. The falling direction of the granular material is as follows: Figure 6 As shown by the solid arrow in the middle; when the solenoid valve 8 is opened to the set time, the controller controls the solenoid valve 8 to close, thereby completing the first impact on the material layer 3 on the end cover 2;

[0010] S14, dumping the granular material in the reactor: the worker controls the piston rods of the two clamping cylinders 9 to retract upward, and the piston rods drive the pressure head 10 to move upward. When the pressure head 10 is separated from the reactor body 1, the worker removes the reactor from the two support seats 5; after removal, the worker dumps the granular material in the reactor to prepare for the second impact on the material layer 3;

[0011] S15, the worker repeats the operations of steps S11 to S14 for 80 times, and finally completes multiple impacts on the material layer 3 on the end cover 2;

[0012] S2. After impacting the end cover 2 of the reactor for multiple times, the worker touches the detection rod of the circular runout meter to the bottom surface of the end cover 2, and then moves the circular runout meter back and forth. If the worker observes that the pointer of the circular runout meter changes, it means that the end cover 2 of the reactor has been deformed downward, which further means that the material layer 3 on the end cover 2 has also been deformed downward. The worker determines that the impact resistance of the material layer 3 on the end cover 2 does not meet the requirements, and determines that the reactor is a defective product. The worker transfers the defective product to the rework process in the workshop to repair the material layer in the defective product;

[0013] If the worker observes that the pointer of the circular runout meter has not changed, it means that the end cover 2 of the reactor has not been deformed downward, and further, it means that the material layer 3 on the end cover 2 has not been deformed downward. The worker determines that the impact resistance of the material layer 3 on the end cover 2 meets the requirements and determines that the reactor is a qualified product. The worker transfers the qualified products to the packing process in the workshop, thus finally completing the impact resistance test of the material layer 3 on the end cover 2 of the first reactor;

[0014] S3. The worker repeats the operations of steps S1 to S2 for multiple times, and can continuously perform impact resistance tests on the material layers on the end covers 2 of multiple reactors in the workshop.

[0015] However, although the testing machine used in the workshop can perform impact resistance test on the material layer 3 on each reactor end cover 2, in actual operation, the following technical defects are still reflected:

[0016] I. In steps S11 to S14, each time the granular material in the discharge bin 7 is used to impact the material layer 3 on the reactor end cover 2, the granular material remaining in the reactor needs to be manually dumped out to prepare for the second impact on the material layer 3; and the number of impacts is as many as 81 times, and the granular material in the reactor needs to be manually dumped out each time, which not only increases the work intensity of the workers, but also takes a long time to complete 81 impacts on the material layer 3 on the end cover 2, which undoubtedly reduces the test efficiency of the impact resistance of the material layer 3 on the reactor end cover 2.

[0017] II. In step S2, after the workers use the circular runout table to determine the defective products and qualified products, the workers need to manually transfer the defective products to the rework process in the workshop, and also need to manually transfer the qualified products to the subsequent packing process. The entire turnover distance is long, which undoubtedly prolongs the test time for the impact resistance of the material layer 3 on the other reactor end covers 2, and further reduces the test efficiency of the impact resistance of the material layer 3 on the reactor end cover 2.

[0018] Therefore, there is an urgent need for a testing device and method that can greatly reduce the workload of workers and greatly improve the efficiency of testing the impact resistance of the material layer on the end cover of the reactor. Summary of the invention

[0033] A method for testing the impact resistance of a material layer on a reactor end cover comprises the following steps:

[0034] S1. Use the granular material in the discharge bin to impact the material layer on the end cover multiple times. The specific operation steps are as follows:

[0035] S11 The worker supports the end cover of the reactor to be tested in the area surrounded by the stoppers of the two positioning seats;

[0036] S12, the left and right piston rods of the double-acting oil cylinder controlling the clamping and lifting mechanism are both retracted inwards, the piston rod drives the movable plate to move synchronously, and the movable plate drives the positioning seat to move synchronously. When the two piston rods of the double-acting oil cylinder are fully retracted, the end cover of the reactor is just clamped and fixed between the two positioning seats, thereby achieving the clamping and fixing of the reactor. At this time, the middle of the end cover of the reactor is just below the center hole of the rectangular plate;

[0037] S13, the solenoid valve is controlled to start, and the granular materials in the discharge bin fall from the solenoid valve under their own gravity, and the fallen granular materials pass through the center of the rectangular plate and enter the reactor body, and then the granular materials hit the material layer; when the solenoid valve is opened to the set time, the controller controls the solenoid valve to close, thereby completing the first impact on the material layer on the end cover;

[0038] S14, dumping of the granular material in the reactor, the specific operation steps are:

[0039] S14a, control the self-locking motors of the two blocking mechanisms to start, the self-locking motor drives the gear to rotate, the gear drives the rack to move inward, and the rack drives the blocking plate connected thereto to move inward synchronously, that is, the two blocking plates move toward each other. When the self-locking motor moves to the set time, the controller controls the self-locking motor to close. At this time, the two blocking plates just block the top port of the reactor body;

[0040] S14b, control the driving motor of the rotating mechanism to start, the driving motor drives the main shaft to rotate, the main shaft drives the support plate to rotate synchronously, the support plate drives the turntable to rotate downward synchronously, when the turntable drives the two blocking mechanisms, the clamping and lifting mechanisms thereon to rotate downward synchronously, and then drives the reactor to move downward synchronously, when the reactor rotates downward 180°, the controller controls the driving motor to turn off, at this time, the reactor body is just facing the material receiving box;

[0041] S14c, control the self-locking motors of the two blocking mechanisms to reverse, the self-locking motor drives the gear to reverse, the gear drives the rack to move outward, and the rack drives the blocking plate to move outward synchronously, that is, the two blocking plates move in opposite directions. When the self-locking motor moves to the set time, the controller controls the self-locking motor to close. At this time, the two blocking plates no longer block the top port of the reactor body. At the same time, the granular materials in the reactor are dumped into the material receiving box, thereby realizing the dumping of all the granular materials in the reactor to prepare for the second impact on the material layer;

[0042] S15, the worker repeats the operations of steps S11 to S14 80 times, and finally completes multiple impacts on the material layer on the end cover;

[0043] S2. After the end cover of the reactor is impacted multiple times, the worker controls the drive motor of the rotating mechanism to start, so that the impacted reactor rotates upward. When the reactor is reset, the controller controls the drive motor to shut down;

[0044] The worker touches the detection rod of the circular runout meter to the bottom surface of the end cover, and then moves the circular runout meter back and forth. If the worker observes that the pointer of the circular runout meter changes, it means that the end cover of the reactor has been deformed downward, which further indicates that the material layer on the end cover has also been deformed downward. The worker determines that the impact resistance of the material layer on the end cover does not meet the requirements and determines that the reactor is a defective product. The worker removes the defective products and transfers them to the rework station in the workshop. The operation steps are as follows:

[0045] S21a, control the chuck A of the right clamping cylinder of the material unloading and turnover mechanism to open, the chuck A of the right clamping cylinder no longer clamps the rectangular plate, while the chuck A of the left clamping cylinder still clamps and fixes the left end of the rectangular plate;

[0046] S22b, control the two piston rods of the double-acting oil cylinder to extend outward, the piston rod drives the positioning seat to move outward, and the two positioning seats no longer clamp the defective products; then, the worker controls the piston rods of the two lifting oil cylinders to extend upward, the piston rod drives the lifting head to move upward, and the lifting head lifts the defective products upward. At this time, the left and right side walls of the kettle body of the defective products enter the clamping heads B of the two vertical clamping oil cylinders respectively;

[0047] S23c, control the clamps B of the two vertical clamping cylinders to close, and the two clamps B clamp and fix the left and right side walls of the defective product;

[0048] S23d, control the left unloading motor to start, the left unloading motor drives the left clamping cylinder to rotate synchronously to the left, the chuck A of the left clamping cylinder drives the rectangular plate to rotate synchronously to the left, the rectangular plate drives the two vertical clamping cylinders to rotate synchronously to the left, the vertical clamping cylinder drives the unqualified products to rotate synchronously to the left, when the unqualified products rotate to the top of the left roller conveyor, the controller controls the left unloading motor to turn off; then, control the two vertical clamping cylinders to start, the chuck B of the two vertical clamping cylinders to open, at this time, the unqualified products fall onto the left roller conveyor, and the left roller conveyor conveys the unqualified products to the rework process in the workshop, thereby realizing the automatic unloading and turnover of unqualified products;

[0049] If the worker observes that the pointer of the circular runout meter has not changed, it means that the end cover of the reactor has not been deformed downward, and further, it means that the material layer on the end cover has not been deformed downward. The worker determines that the impact resistance of the material layer on the end cover meets the requirements and determines that the reactor is a qualified product. The worker unloads the qualified products and transfers them to the packing process in the workshop in the following steps:

[0050] S21aa, the chuck A of the left clamping cylinder of the control unloading and turnover mechanism is opened, and the chuck A of the left clamping cylinder no longer clamps the rectangular plate, while the chuck A of the right clamping cylinder still clamps and fixes the right end of the rectangular plate;

[0051] S22bb, control the two piston rods of the double-acting oil cylinder to extend outward, and the piston rod drives the positioning seat to move outward, and the two positioning seats no longer clamp the qualified products; then, the worker controls the piston rods of the two lifting oil cylinders to extend upward, and the piston rod drives the lifting head to move upward, and the lifting head lifts the qualified products upward. At this time, the left and right side walls of the kettle body of the qualified products enter the clamping heads B of the two vertical clamping oil cylinders respectively;

[0052] S23cc, control the clamps B of the two vertical clamping cylinders to close, and the two clamps B clamp and fix the left and right side walls of the qualified product;

[0053] S23dd, control the right unloading motor to start, the right unloading motor drives the right clamping cylinder to rotate right synchronously, the chuck A of the right clamping cylinder drives the rectangular plate to rotate right synchronously, the rectangular plate drives the two vertical clamping cylinders to rotate right synchronously, the vertical clamping cylinder drives the qualified products to rotate right synchronously, when the qualified products rotate to the top of the right roller conveyor, the controller controls the right unloading motor to turn off; then, control the two vertical clamping cylinders to start, the chuck B of the two vertical clamping cylinders to open, at this time, the qualified products fall onto the right roller conveyor, the right roller conveyor transports the qualified products to the packing process in the workshop, thereby realizing the automatic unloading and turnover of qualified products, and finally completing the impact resistance test of the material layer on the end cover of the first reactor;

Fig.19 As shown, the reaction kettle is clamped and fixed, and at this time, the middle of the end cover 2 of the reaction kettle is just below the center hole 36 of the rectangular plate 35;

[0105] S13, control the solenoid valve 8 to start, the granular material in the discharge bin 7 falls from the solenoid valve 8 under its own gravity, and the fallen granular material passes through the center of the rectangular plate 35 and enters the reactor body 1, and then the granular material hits the material layer 3. The impact direction of the granular material is as follows: Fig.19 As shown by the solid arrow in the middle; when the solenoid valve 8 is opened to the set time, the controller controls the solenoid valve 8 to close, thereby completing the first impact on the material layer 3 on the end cover 2;

[0106] S14, dumping of the granular material in the reactor, the specific operation steps are:

[0107] S14a, control the self-locking motors 22 of the two blocking mechanisms 13 to start, the self-locking motors 22 drive the gear 25 to rotate, the gear 25 drives the rack 24 to move inward, the rack 24 drives the blocking plate 23 connected thereto to move inward synchronously, that is, the two blocking plates 23 move toward each other, when the self-locking motor 22 moves to the set time, the controller controls the self-locking motor 22 to close, at this time, the two blocking plates 23 just block the top port of the reactor body 1, as shown in FIG. Fig. 20 As shown;

[0108] S14b, control the driving motor 29 of the rotating mechanism 11 to start, the driving motor 29 drives the main shaft 27 to rotate, the main shaft 27 drives the support plate to rotate synchronously, the support plate drives the turntable 28 to rotate downward synchronously, when the turntable 28 drives the two blocking mechanisms 13 and the clamping and lifting mechanism 12 thereon to rotate downward synchronously, and then drives the reactor to move downward synchronously, when the reactor rotates downward 180°, the controller controls the driving motor 29 to turn off, at this time, the reactor body 1 is just facing the material receiving box 41, as shown in FIG. Fig.21 As shown;

[0109] S14c, control the self-locking motors 22 of the two blocking mechanisms 13 to reverse, the self-locking motors 22 drive the gears 25 to reverse, the gears 25 drive the racks 24 to move outward, the racks 24 drive the blocking plates 23 to move outward synchronously, that is, the two blocking plates 23 move in opposite directions, when the self-locking motors 22 move to the set time, the controller controls the self-locking motors 22 to turn off, at this time, the two blocking plates 23 no longer block the top port of the reactor body 1, such as Fig. 22 As shown, at the same time, the granular material in the reactor is poured into the material receiving box 41, and the pouring direction of the granular material is as follows Fig. 22 As shown by the hollow arrow, all the granular materials in the reactor are dumped out to prepare for the second impact on the material layer 3;

[0110] S15, the worker repeats the operations of steps S11 to S14 for 80 times, and finally completes multiple impacts on the material layer 3 on the end cover 2;

[0111] Among them, it can be known from steps ~S13~S14 that each time the granular material in the discharge bin 7 is used to impact the material layer 3 on the reactor end cover 2, the worker only needs to control the self-locking motors 22 of the two blocking mechanisms 13 to start, so as to block the top port of the reactor body 1 through the two blocking plates 23. The purpose of blocking is to prevent the granular material in the reactor from scattering around during the rotation of the reactor, so as to facilitate the collection of all the used granular materials into the material receiving box 41; then, the drive motor 29 of the rotating mechanism 11 is controlled to start, so that the reactor rotates to the dumping position; finally, the self-locking motors 22 of the two blocking mechanisms 13 are controlled to start, so that the two blocking plates 23 move in the opposite direction, and the two blocking plates 23 no longer block the top port of the reactor body 1. At this time, all the granular materials in the reactor are dumped into the material receiving box 41.

[0112] It can be seen that the testing device only needs the linkage of the blocking mechanism 13 and the rotating mechanism 11 to automatically dump the used granular materials in the reactor. Therefore, compared with the testing device in the workshop, Figure 3~Figure 6 The testing machine shown does not need to manually dump the granular material in the reactor every time after the granular material impacts the material layer 3 on the end cover 2, thereby greatly reducing the work intensity of the workers. At this time, 81 impacts on the material layer 3 on the end cover 2 are completed in a short time, thereby greatly improving the test efficiency of the impact resistance of the material layer 3 on the end cover 2 of the reactor.

[0113] S2, after the end cover 2 of the reactor is impacted multiple times, the worker controls the drive motor 29 of the rotating mechanism 11 to start, so that the impacted reactor rotates upward, and when the reactor is reset, the controller controls the drive motor 29 to turn off;

[0114] The worker touches the detection rod of the circular runout meter to the bottom surface of the end cover 2 in the contact direction. Fig.23 As shown by the middle arrow, the worker then moves the circular runout meter back and forth. If the worker observes that the pointer of the circular runout meter has changed, it means that the end cover 2 of the reactor has been deformed downward, which further means that the material layer 3 on the end cover 2 has also been deformed downward. The worker determines that the impact resistance of the material layer 3 on the end cover 2 does not meet the requirements and determines that the reactor is a defective product 42. The worker unloads the defective product 42 and transfers it to the rework station in the workshop in the following operating steps:

[0115] S21a, control the clamping head A34 of the right clamping cylinder 33 of the material unloading and turnover mechanism to open, and the clamping head A34 of the right clamping cylinder 33 no longer clamps the rectangular plate 35, such as Fig.24 As shown, the clamp A34 of the left clamping cylinder 32 still clamps and fixes the left end of the rectangular plate 35;

[0116] S22b, control the two piston rods of the double-acting oil cylinder 14 to extend outward, and the piston rod drives the positioning seat 16 to move outward, and the two positioning seats 16 no longer clamp the unqualified product 42; then, the worker controls the piston rods of the two lifting oil cylinders 18 to extend upward, and the piston rod drives the lifting head 19 to move upward, and the lifting head 19 lifts the unqualified product 42 upward. At this time, the left and right side walls of the kettle body 1 of the unqualified product 42 respectively enter the clamping heads B38 of the two vertical clamping oil cylinders 37, as shown in FIG. Fig.25 As shown;

[0117] S23c, control the clamps B38 of the two vertical clamping cylinders 37 to close, and the two clamps B38 clamp and fix the left and right side walls of the defective product 42, such as Fig.26 As shown;

[0118] S23d, control the left feeding motor 30 to start, the left feeding motor 30 drives the left clamping cylinder 32 to rotate synchronously to the left, the clamping head A34 of the left clamping cylinder 32 drives the rectangular plate 35 to rotate synchronously to the left, the rectangular plate 35 drives the two vertical clamping cylinders 37 to rotate synchronously to the left, the vertical clamping cylinder 37 drives the unqualified product 42 to rotate synchronously to the left, when the unqualified product 42 rotates to the top of the left roller conveyor 39, as shown in FIG. Fig. 27 As shown, the controller controls the left feeding motor 30 to turn off; then, the two vertical clamping cylinders 37 are controlled to open, and the clamps B38 of the two vertical clamping cylinders 37 are opened. At this time, the unqualified products 42 fall onto the left roller conveyor 39, and the left roller conveyor 39 conveys the unqualified products 42 to the rework process in the workshop. The conveying direction is as shown in FIG. Fig.28 As shown by the middle arrow, automatic unloading and turnover of defective products 42 are achieved;

[0119] If the worker observes that the pointer of the circular runout meter has not changed, it means that the end cover 2 of the reactor has not been deformed downward, and further, it means that the material layer 3 on the end cover 2 has not been deformed downward. The worker determines that the impact resistance of the material layer 3 on the end cover 2 meets the requirements and determines that the reactor is a qualified product 43. The worker unloads the qualified product 43 and transfers it to the packing process in the workshop in the following operation steps:

[0120] S21aa, control the chuck A34 of the left clamping cylinder 32 of the material unloading and turnover mechanism to open, and the chuck A34 of the left clamping cylinder 32 no longer clamps the rectangular plate 35, such as Fig.29 As shown, the clamp A34 of the right clamping cylinder 33 still clamps and fixes the right end of the rectangular plate 35;

[0121] S22bb, control the two piston rods of the double-acting oil cylinder 14 to extend outward, and the piston rod drives the positioning seat 16 to move outward, and the two positioning seats 16 no longer clamp the qualified product 43; then, the worker controls the piston rods of the two lifting oil cylinders 18 to extend upward, and the piston rod drives the lifting head 19 to move upward, and the lifting head 19 lifts the qualified product 43 upward. At this time, the left and right side walls of the kettle body 1 of the qualified product 43 respectively enter the clamping heads B38 of the two vertical clamping oil cylinders 37, as shown in FIG. Fig.30 As shown;

[0122] S23cc, control the clamps B38 of the two vertical clamping cylinders 37 to close, and the two clamps B38 clamp and fix the left and right side walls of the qualified product 43;

[0123] S23dd, control the right feeding motor 31 to start, the right feeding motor 31 drives the right clamping cylinder 33 to rotate right synchronously, the clamping head A34 of the right clamping cylinder 33 drives the rectangular plate 35 to rotate right synchronously, the rectangular plate 35 drives the two vertical clamping cylinders 37 to rotate right synchronously, the vertical clamping cylinder 37 drives the qualified product 43 to rotate right synchronously, when the qualified product 43 rotates to the top of the right roller conveyor 40, as shown in FIG. Fig.31 As shown, the controller controls the right unloading motor 31 to turn off; then, the two vertical clamping cylinders 37 are controlled to open, and the clamps B38 of the two vertical clamping cylinders 37 are opened. At this time, the qualified products 43 fall onto the right roller conveyor 40, and the right roller conveyor 40 conveys the qualified products 43 to the packing process in the workshop. The conveying direction is as shown in FIG. Fig.32 As shown by the middle arrow, the automatic unloading and turnover of qualified products 43 are realized, and the impact resistance test of the material layer 3 on the end cover 2 of the first reactor is finally completed;

[0124] S3. The worker repeats the operations of steps S1 to S2 for multiple times, and can continuously perform impact resistance tests on the material layers on the end covers 2 of multiple reactors in the workshop.

[0125] Among them, from step S2, when the worker uses the circular runout table to determine that the tested reactor is a defective product 42 or a qualified product 43, the defective product 42 after the test can be automatically transferred to the rework process in the workshop, and the qualified product 43 can be automatically transferred to the packing process in the workshop, only through the linkage coordination of the lifting cylinder 18 of the clamping and lifting mechanism 12 and the left unloading motor 30, the right unloading motor 31, the left clamping cylinder 32, the right clamping cylinder 33, and the vertical clamping cylinder 37 of the unloading and turnover mechanism.

[0126] It can be seen that compared with the testing machine in the workshop, the present testing device does not require manual turnover of defective products 42 and qualified products 43, but realizes automatic unloading and turnover of defective products 42 and qualified products 43, and realizes the testing time of the impact resistance of the material layer 3 on the end cover 2 of other reactors in a short time, which further greatly improves the testing efficiency of the impact resistance of the material layer 3 on the end cover 2 of the reactor.
