Description

Technical Field

[0001] The present invention relates to the technical field of filter tube performance detection, specifically to a performance detection device for ceramic fiber filter tubes based on big data. Background Art

[0002] A filter tube is a new type of permeable drainage plastic pipe with a corrugated shape formed by adding other additives to high-density polypropylene. The permeable corrugated pipe is processed by punching holes in the grooves and wrapping polyester spunbond non-woven geotextile around the outer periphery of the pipe;

[0003] In the prior art, when detecting the anti-deformation performance of ceramic fiber filter tubes, a heavy hammer is mostly used to directly impact the ceramic fiber filter tubes multiple times for inspection. If the ceramic fiber filter tubes do not undergo cracking deformation after multiple impacts, it indicates that the anti-deformation performance of the ceramic fiber filter tubes is better. During the detection process, the knocking position of the heavy hammer is small, which is easy to cause damage to the ceramic fiber filter tubes, and the falling position and impact force are not easy to control, causing trouble to the testers; when detecting the air permeability performance of ceramic fiber filter tubes, it is necessary to remove the filter tube body after the anti-deformation detection and then use air permeability detection equipment for detection. During the detection process, it is necessary to disassemble and remove the filter tube body and then reinstall and fix the position of the filter tube body again, and the operation is relatively cumbersome. Moreover, the air permeability detection equipment consumes electric power resources during detection; when detecting the performance of ceramic fiber filter tubes, the impurities and debris attached to the inner and outer side walls of the filter tube body are likely to have an adverse effect on the detection results;

[0004] In view of the above technical problems, this application proposes a solution. Summary of the Invention

[0005] The purpose of the present invention is to limit the position of the filter tube body, and then the extrusion plate impacts the filter tube body under the action of the extrusion spring to detect the anti-deformation performance. The large area of the extrusion plate will not cause damage to the filter tube body. The air storage airbag is used to transmit air inside the detection air cylinder to detect the air permeability performance of the filter tube body. During the detection process, the air permeability performance of the filter tube body and whether the filter tube body is cracked can be judged by the wind speed detected by the wind speed sensor on the outside. When the filter tube body rotates, the upper and lower scraping knives clean the impurities on the filter tube body, so as to solve the problems that the anti-deformation performance detection of the filter tube is easy to cause damage to the filter tube, the air permeability detection requires disassembly and reinstallation of the filter tube body, and the impurities outside the filter tube body have an adverse effect on the performance detection, and a performance detection device for ceramic fiber filter tubes based on big data is proposed.

At the middle position of the outer walls of the extrusion plate and the positioning plate, there is a connection with a control switch.

[0009] As a preferred embodiment of the present invention, at one end of the upper surface of the bottom plate corresponding to the filter tube body, there is a rotational connection with a support ring through a rotating seat. Inside the support ring, there is a sliding connection with a rotating ring. On both sides of the outer wall of the rotating ring, there are connection limiting cards. On both sides of the outer wall of the support ring corresponding to the positions of the limiting cards, there are connection limiting blocks. Inside the inner wall of the rotating ring, there is a sleeved detection air cylinder. On one side of the outer wall of the detection air cylinder, there are a number of uniformly distributed exhaust holes opened.

[0010] As a preferred embodiment of the present invention, on the upper surface of the connecting rod, there are engaged tooth grooves opened. On the outer wall of the fixed plate near the connecting rod corresponding to the positions of the engaged tooth grooves, there is a rotational connection with an engaged gear. On one side of the outer wall of the engaged gear, there is a connection with a connecting rotating shaft. On the upper surface of the bottom plate near the position of the connecting rotating shaft, there is a rotational connection with a reciprocating lead screw through a support frame. One end of both the reciprocating lead screw and the connecting rotating shaft is connected with an air storage rotating wheel. The two air storage rotating wheels are connected by a transmission belt. On the outer wall of the reciprocating lead screw, there is a sliding connection with a reciprocating plate. On one side of the outer wall of the reciprocating plate, there is a connection with a telescopic hose. The end of the telescopic hose far from the reciprocating plate is connected with an air storage airbag. The end of the air storage airbag far from the telescopic hose is connected with a docking pipe through a hose.

[0011] As a preferred embodiment of the present invention, a pressure gauge is connected to the outer side wall of the air storage airbag. A limiting plate is connected to the outer side wall of the support frame near the lower part of the reciprocating lead screw. A switch valve is connected to the outer side wall of the docking pipe. Check valves are provided at both ends of the telescopic hose.

[0012] As a preferred embodiment of the present invention, a support plate is connected to the outer side wall of the positioning plate on the side close to the filter pipe body. An upper scraping blade is connected to the upper part of the outer side wall of the support plate. A lower scraping blade is connected to the lower part of the outer side wall of the support plate.

[0013] As a preferred embodiment of the present invention, a debris groove is connected to the lower surface of the lower scraping blade. A chip flow groove is integrally formed on the lower surface of the debris groove. A chip flow auger is rotatably connected to the inner side wall of the debris groove through a connecting shaft. One end of the chip flow auger far from the debris groove is connected to a chip flow runner. A propeller blade is rotatably connected to the inner side wall of the docking pipe.

[0014] As a preferred embodiment of the present invention, the electronic control system is further configured to receive the wind speed data sent by the wind speed sensor, compare the wind speed data with the preset wind speed data in the large database to obtain the air permeability of the filter pipe body.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. After the position of the filter pipe body is limited by the extrusion plate and the positioning plate, the electronic control system obtains the corresponding contraction data of the electric push rod according to the force data input by the detection personnel. After the electric push rod contracts by the corresponding length under the control of the electronic control system, the traction on the traction plate is released, so that the extrusion plate impacts the filter pipe body under the action of the elastic rebound of the extrusion spring to perform the anti-deformation performance test. The large area of the extrusion plate will not damage the filter pipe body.

[0017] 2. During the anti-deformation performance test, the engaging tooth grooves on the connecting rod drive the engaging gear to rotate, so that the connecting rotating shaft connecting the engaging gear drives the reciprocating lead screw to rotate through the transmission belt, and the telescopic hose sucks the outside air and transmits it into the air storage airbag to perform the air permeability test of the filter pipe body on the inside of the detection air cylinder. During the test, the air permeability of the filter pipe body and whether the filter pipe body is cracked can be judged by the wind speed detected by the wind speed sensor on the outside.

[0018] 3. The propeller blades inside the connecting pipe rotate driven by the air flow, causing the chip auger to drive the driving roller to rotate during rotation, and enabling the filter pipe body to rotate supported by the supporting rollers. When the filter pipe body rotates, the upper and lower scrapers can clean the impurities on the filter pipe body, and the magnitude of the deformation of the filter pipe body can be judged by the magnitude of the tensile force data detected by the tensile force sensor for the position movement of the upper scraper.

Detailed implementation manners

[0030] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Embodiment 1:

[0032] Please refer to Figures 1-4 and Figure 6As shown in the figure, a performance detection device for ceramic fiber filter tubes based on big data includes a bottom plate 1. On one side of the upper surface of the bottom plate 1, there is a filter tube body 25. The inner diameter of the filter tube body 25 is larger than the outer diameter of the detection air cylinder 211. On the side of the upper surface of the bottom plate 1 close to the filter tube body 25, there is a sliding connection with an extrusion plate 24. On the other side of the upper surface of the bottom plate 1 close to the filter tube body 25, there is a sliding connection with a positioning plate 27. Both the extrusion plate 24 and the positioning plate 27 are of frame structure. On both sides of the upper surface of the bottom plate 1 corresponding to the extrusion plate 24 and the positioning plate 27, there are sliding grooves 21. At the positions corresponding to the sliding grooves 21 on the lower surfaces of the extrusion plate 24 and the positioning plate 27, there are integrally formed sliding blocks 213. At the lower surface inside the sliding groove 21, there is an iron suction block connected. At the lower end of the sliding block 213, there is an electromagnet connected. At the middle position of the outer side walls of the extrusion plate 24 and the positioning plate 27, there is a control switch 28, so that the positions of the extrusion plate 24 and the positioning plate 27 on the bottom plate 1 can be limited by the mutual adsorption of the electromagnet at the lower end of the sliding block 213 and the iron suction block inside the sliding groove 21. The control switch 28 can control the on-off of the electromagnet. On the upper surface of the bottom plate 1 close to the extrusion plate 24, there is a fixed plate 23 connected. At the middle position of the outer side wall of the fixed plate 23 close to the extrusion plate 24, there is an infrared distance sensor connected. The infrared distance sensor can detect the distance between the extrusion plate 24 and the fixed plate 23 during the movement process. On both sides of the outer side wall of the fixed plate 23 close to the extrusion plate 24, there are extrusion springs 29 connected. On the inner side of the outer side wall of the extrusion plate 24 corresponding to the extrusion springs 29, there is a connecting rod 215 connected. At the end of the connecting rod 215 away from the extrusion plate 24, there is a traction plate 22 connected. At the middle position of the outer side wall of the traction plate 22, there is a magnetic attraction block 214 connected. On the upper surface of the bottom plate 1 corresponding to the magnetic attraction block 214, there is an electric push rod connected. At the end of the electric push rod corresponding to the magnetic attraction block 214, there is a magnetic attraction iron connected. After the magnetic attraction iron at one end of the electric push rod is adsorbed to the magnetic attraction block 214, during the telescopic process of the electric push rod, it drives the traction plate 22 to move. On both sides of the side close to the filter tube body 25 of the extrusion plate 24 and the positioning plate 27, there are a number of uniformly distributed ventilation holes 26 opened. Inside the extrusion plate 24 and the positioning plate 27 corresponding to the ventilation holes 26, there are wind speed sensors arranged. On one end of the upper surface of the bottom plate 1 corresponding to the filter tube body 25, there is a support ring 210 rotatably connected through a rotating seat 212. The support ring 210 can rotate under the action of the rotating seat 212, which is convenient for rotating the detection air cylinder 211 to adjust the angle, so that the filter tube body 25 is convenient to be placed outside the detection air cylinder 211 for detection. Inside the support ring 210, there is a sliding connection with a rotating ring 217. The rotating ring 217 rotates inside the support ring 210, which can adjust the direction of the exhaust holes 216 on the detection air cylinder 211. On both sides of the outer side wall of the rotating ring 217, there are limit cards 218 connected. On both sides of the outer side wall of the support ring 210 corresponding to the limit cards 218, there are limit blocks 219 connected. The inner side wall of the rotating ring 217 is sleeved with a detection air cylinder 211. On one side of the outer side wall of the detection air cylinder 211, there are a number of uniformly distributed exhaust holes 216;

[0033] In the prior art, when detecting the anti-deformation performance of ceramic fiber filter tubes, the method of directly using a heavy hammer to impact the ceramic fiber filter tube multiple times is mostly adopted for inspection. If the ceramic fiber filter tube does not undergo rupture deformation after multiple impacts, it indicates that the anti-deformation performance of the ceramic fiber filter tube is good. During the detection process, the knocking position of the heavy hammer is small, which is easy to cause damage to the ceramic fiber filter tube, and the falling position and impact force are not easy to control, causing trouble to the detection personnel;

[0034] The detection personnel can adjust the position of the positioning plate 27 on the bottom plate 1 according to the outer diameter size of the filter tube body 25, and limit the position by the mutual adsorption of the electromagnet on the slider 213 below the positioning plate 27 and the iron suction block inside the chute 21, so that the center of the filter tube body 25 coincides with the center of the detection air cylinder 211. Then, input the impact force data of the filter tube body 25 into the electronic control system. The electronic control system compares the input impact force data with the impact force data in the established large database to obtain the corresponding contraction length data of the electric push rod. The data in the established large database is the contraction length data of the electric push rod corresponding to the corresponding impact force data obtained by taking the average value through multiple tests. After the electric push rod receives the contraction length data transmitted by the electronic control system, under the monitoring of the infrared distance sensor, it extends to the set length, and then the magnetic iron at one end of the electric push rod adsorbs with the magnetic block 214. Then the electric push rod contracts to pull the traction plate 22 to move. During the movement, the compression spring 29 deforms and contracts. After the electric push rod contracts a specified length under the monitoring of the infrared distance sensor, it transmits a signal to the electronic control system to cut off the power supply to the magnetic iron, so that the traction plate 22 quickly rebounds under the action of the elastic force of the compression spring 29, so that the pressing plate 24 impacts the filter tube body 25. The length of the pressing plate 24 is greater than the length of the filter tube body 25, so that each position on the side of the filter tube body 25 can be affected by the impact during the impact process. The impact force data can be controlled by the contraction length after comparison with the large database.

[0035] Embodiment 2:

[0036] Please refer to Figure 5 and Figure 7As shown, a fitting tooth groove 33 is formed on the upper surface of the connecting rod 215. A fitting gear 34 is rotatably connected to the outer side wall of the fixing plate 23 at a position corresponding to the fitting tooth groove 33 on the connecting rod 215. The outer teeth of the fitting gear 34 are engaged with the fitting tooth groove 33. During the reciprocating sliding of the connecting rod 215, the fitting gear 34 rotates forward and backward. One side of the outer side wall of the fitting gear 34 is connected with a connecting rotating shaft 32. A reciprocating lead screw 39 is rotatably connected to the upper surface of the bottom plate 1 at a position close to the connecting rotating shaft 32 through a support frame 38. Both ends of the reciprocating lead screw 39 and the connecting rotating shaft 32 are connected with air storage rotating wheels 35. The two air storage rotating wheels 35 are drivingly connected through a transmission belt 36, so that the connecting rotating shaft 32 drives the reciprocating lead screw 39 to rotate through the transmission belt 36. A reciprocating plate 310 is slidably connected to the outer side wall of the reciprocating lead screw 39. During the rotation of the reciprocating lead screw 39, the reciprocating plate 310 makes a reciprocating position movement on the outer side wall of the reciprocating lead screw 39. One side of the outer side wall of the reciprocating plate 310 is connected with a telescopic hose 311. Check valves are arranged at both ends of the telescopic hose 311, so that the end of the telescopic hose 311 away from the air storage airbag 31 sucks air, and the end close to the air storage airbag 31 discharges air. The end of the telescopic hose 311 away from the reciprocating plate 310 is connected with an air storage airbag 31. The end of the air storage airbag 31 away from the telescopic hose 311 is connected with a docking pipe 313 through a hose. The outer diameter of the docking pipe 313 is the same as the inner diameter of the detection air cylinder 211. A pressure gauge 312 is connected to the outer side wall of the air storage airbag 31. A limiting plate 37 is connected to the outer side wall of the support frame 38 below the reciprocating lead screw 39. The limiting plate 37 prevents the reciprocating plate 310 from deviating in direction during the movement. A switch valve is connected to the outer side wall of the docking pipe 313;

[0037] In the prior art, when detecting the air permeability of a ceramic fiber filter tube, the filter tube body 25 after anti-deformation detection needs to be removed and then detected by an air permeability detection device. During the detection process, the filter tube body 25 needs to be disassembled and removed, and then the position of the filter tube body 25 needs to be reinstalled and fixed. The operation is relatively cumbersome, and the air permeability detection device consumes electric power resources during the detection;

[0038] When detecting the anti-deformation performance, the engaging tooth grooves 33 on the connecting rod 215 can drive the engaging gear 34 engaged with the engaging tooth grooves 33 to rotate during the sliding process. The connecting rotating shaft 32 coaxial with the engaging gear 34 drives the reciprocating lead screw 39 to rotate through the transmission belt 36 during the rotation process, so that the reciprocating plate 310 stretches and contracts the telescopic hose 311 during the reciprocating movement, enabling the telescopic hose 311 to fill the outside air into the air storage airbag 31. The pressure gauge 312 detects the pressure of the air storage airbag 31, and when the pressure reaches the set value, it is conveyed into the detection air cylinder 211 from the position of the docking pipe 313. The air entering the detection air cylinder 211 fills the inside of the detection air cylinder 211 and then is discharged from the exhaust hole 216 position of the detection air cylinder 211 to impact the filter tube body 25. Part of the gas leaks out to the outside from the position of the filter tube body 25, and the airflow leaking to the outside can blow the wind speed sensor at the ventilation hole 26 position. The wind speed sensor transmits the detected wind speed magnitude data to the electronic control system for comparison with the wind speed data in the set large database to obtain the air permeability magnitude of the filter tube body 25. The set large database stores the air permeability magnitude of the filter tube body 25 corresponding to the non-ventilation force magnitude obtained from the test.

[0039] Embodiment 3:

[0040] Please refer to Figure 1 and Figure 8As shown in the figure, a support plate 41 is connected to the outer side wall of the positioning plate 27 near the filter tube body 25. The upper scraper 42 and the lower scraper 43 at one end of the support plate 41 are located at the middle position of the filter tube body 25. The upper scraper 42 is connected to the upper side wall of the support plate 41. The upper scraper 42 is slidably connected to the support plate 41 through a sliding groove, and the upper scraper 42 and the support plate 41 are connected by a connecting spring. One end of the connecting spring is connected with a tensile sensor. The lower scraper 43 is connected to the lower side wall of the support plate 41. A driving roller is connected to the position of the side wall of the support plate 41 corresponding to the side wall of the filter tube body 25. One end of the connecting shaft of the driving roller is connected with a bevel gear one. A bevel gear two is rotatably connected to the position of the side wall of the support plate 41 corresponding to the bevel gear one. The bevel gear one and the bevel gear two are perpendicular to each other and engaged with each other, and drive each other to rotate. The runner connected to the outer side wall of the bevel gear two is drivingly connected with the chip flow runner 48 at one end of the chip flow auger 45 through a transmission belt 36. Both the upper scraper 42 and the lower scraper 43 are designed with an inclination angle, and the inclination directions are opposite. A debris groove 44 is connected to the lower surface of the lower scraper 43. A chip flow groove 46 is integrally formed on the lower surface of the debris groove 44. A chip flow auger 45 is rotatably connected to the inner side wall of the debris groove 44 through a connecting shaft. One end of the chip flow auger 45 away from the debris groove 44 is connected with a chip flow runner 48. A propeller blade 47 is rotatably connected to the inner side wall of the docking pipe 313. The propeller blade 47 is driven to rotate during the airflow flowing inside the docking pipe 313. The connecting shaft of the propeller blade 47 is drivingly connected with the chip flow runner 48 through a transmission belt 36. Support rollers are connected to the upper surface of the bottom plate 1 corresponding to the position of the filter tube body 25;

[0041] In the prior art, when detecting the performance of the ceramic fiber filter tube, the impurity debris attached to the inner and outer side walls of the filter tube body 25 can easily have an adverse effect on the test results;

[0042] When the airflow inside the air storage airbag 31 flows through the docking pipe 313 into the detection air cylinder 211, it drives the propeller blade 47 inside the docking pipe 313 to rotate. During the rotation of the propeller blade 47, the chip flow auger 45 is driven to rotate through the transmission belt 36. The upper scraper 42 and the lower scraper 43 connected to the support plate 41 are respectively in contact with the outer wall and the inner wall of the filter tube body 25. The filter tube body 25 rotates through the rotation of the driving roller under the support of the support rollers. During the rotation, the upper scraper 42 and the lower scraper 43 respectively clean the outer wall and the inner wall of the filter tube body 25. The impurities scraped from the outer wall of the filter tube body 25 fall off during the rotation of the outer wall. After the impurities scraped from the inner wall fall into the debris groove 44, they are driven by the chip flow auger 45 inside the chip flow groove 46 to be discharged towards one end of the chip flow groove 46, and will not fall into the filter tube body 25 to cause blockage at other positions of the inner wall.

[0043] When the present invention is in use, the tester can adjust the position of the positioning plate 27 on the bottom plate 1 according to the outer diameter of the filter tube body 25, and limit the position by the mutual adsorption of the electromagnet on the slider 213 below the positioning plate 27 and the iron suction block inside the chute 21, so that the center of the filter tube body 25 coincides with the center of the detection air cylinder 211. Then, input the impact force data of the filter tube body 25 into the electronic control system. The electronic control system compares the input impact force data with the impact force data in the established large database to obtain the corresponding contraction length data of the electric push rod. The data in the established large database are the contraction length data of the electric push rod corresponding to the corresponding impact force data obtained by averaging through multiple tests. After receiving the contraction length data transmitted by the electronic control system, the electric push rod extends to the set length, and then the magnetic iron at one end of the electric push rod adsorbs with the magnetic suction block 214. Then, the electric push rod contracts to pull the traction plate 22 to move. During the movement, the compression spring 29 deforms and contracts. After the electric push rod contracts a specified length, it transmits a signal to the electronic control system to cut off the power supply to the magnetic iron, so that the traction plate 22 quickly rebounds under the action of the elastic force of the compression spring 29, and the extrusion plate 24 impacts the filter tube body 25. The length of the extrusion plate 24 is greater than the length of the filter tube body 25, so that each position on the side of the filter tube body 25 can be affected by the impact during the impact process. The impact force data can be controlled by the contraction length after comparison with the large database;

[0044] When detecting the anti-deformation performance, the engaging tooth grooves 33 on the connecting rod 215 can drive the engaging gear 34 engaged with the engaging tooth grooves 33 to rotate during the sliding process. The connecting rotating shaft 32 coaxial with the engaging gear 34 drives the reciprocating lead screw 39 to rotate through the transmission belt 36 during the rotation process, so that the reciprocating plate 310 stretches and contracts the telescopic hose 311 during the reciprocating movement, enabling the telescopic hose 311 to fill the outside air into the air storage airbag 31. The pressure gauge 312 detects the pressure of the air storage airbag 31, and when the pressure reaches the set value, it is conveyed into the detection air cylinder 211 from the position of the docking pipe 313. The air entering the detection air cylinder 211 is discharged from the exhaust hole 216 position of the detection air cylinder 211 after filling the inside of the detection air cylinder 211 to impact the filter tube body 25. Part of the gas leaks out to the outside from the position of the filter tube body 25, and the airflow leaking to the outside can blow the wind speed sensor at the ventilation hole 26 position. The wind speed sensor transmits the detected wind speed magnitude data to the electronic control system, and the electronic control system compares it with the wind speed data in the set large database to obtain the air permeability magnitude of the filter tube body 25. The set large database stores the air permeability magnitude of the filter tube body 25 corresponding to the non-ventilation force magnitude obtained from the test. The wind speed sensor at the ventilation hole 26 position can detect each position on the filter tube body 25 during the rotation of the filter tube body 25. When the wind speed sensor transmits the detected data to the electronic control system for determination, when the wind speed data is less than the set value, it is determined that there is a blockage on the filter tube body 25, and when the wind speed data is greater than the set value, it is determined that there is a crack on the filter tube body 25, making it more convenient for the tester not to manually check for cracks on the filter tube body 25 after the anti-deformation performance test;

[0045] When the air flow inside the air storage airbag 31 flows into the inside of the detection air cylinder 211 through the docking pipe 313, it drives the propeller blade 47 inside the docking pipe 313 to rotate. During the rotation of the propeller blade 47, the chip conveyor auger 45 is driven to rotate through the transmission belt 36. The upper scraper 42 and the lower scraper 43 connected to the support plate 41 are respectively in contact with the outer wall and the inner wall of the filter tube body 25. The filter tube body 25 rotates through the rotation of the driving roller under the support of the support rollers. During the rotation, the upper scraper 42 and the lower scraper 43 respectively clean the outer wall and the inner wall of the filter tube body 25. The impurities cleaned from the outer wall of the filter tube body 25 fall off during the rotation of the outer wall. After the impurities cleaned from the inner wall fall into the debris trough 44, they are driven by the chip conveyor auger 45 inside the chip chute 46 to be discharged towards one end of the chip chute 46, and will not fall into the inside of the filter tube body 2 fifty, causing blockage at other positions on the inner wall. During the anti-deformation performance detection, when the filter tube body 25 deforms under the impact, the extrusion force of the filter tube body 25 on the upper scraper 42 becomes larger, causing the position of the upper scraper 42 to shift. When shifting, the connecting spring pulls the traction force sensor. The traction force sensor can still detect the traction force data after the filter tube body 25 deforms, enabling the tester to judge that the filter tube body 25 has a large deformation during the anti-deformation detection based on the non-zero traction force data transmitted to the electronic control system.
