Tension detection device for ultrafiltration membrane fibers

Abstract

This utility model discloses a tension detection device for ultrafiltration membrane fibers, including a base and a crossbeam. Beneficial effects: This utility model employs a top wheel, base, electric cylinder, and crossbeam. When detecting the tension of ultrafiltration membrane fibers, the device can be mounted on the outside of the membrane fibers. The top wheel is then aligned with the moving membrane fibers. The electric cylinder is then activated to shorten, causing the crossbeam and top wheel to move downwards. The top wheel rolls and contacts the membrane fibers, pushing them downwards and deforming them, forming an angle with the top wheel. The internal tension of the membrane fibers creates a compressive force on the top wheel. This force is transmitted to a pressure sensor via the wheel frame, and the pressure value is displayed on the pressure display. The pressure value is positively correlated with the tension, allowing the membrane fiber tension to be calculated. This device has a simple structure, can simultaneously detect the tension of multiple sets of membrane fibers in large quantities, has high mobility and high working efficiency, and requires no modification to existing equipment; it can be quickly deployed simply by mounting it on the outside of the membrane fibers, making it more practical.

Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and more specifically, to a tension testing device for membrane fibers of ultrafiltration membranes. Background Technology

[0002] With the development of industrial technology, modern testing equipment technology has become increasingly sophisticated. Ultrafiltration membranes are composed of many membrane fibers. These membrane fibers need to be tested during production. In the past, membrane fiber testing devices could only test one membrane fiber at a time, which made the testing efficiency low.

[0003] After searching, it was found that application number CN202421056950.1, entitled "A Membrane Tension Detection Device for Immersive Ultrafiltration Membranes," proposed that membrane fibers need to undergo extensive testing to obtain accurate average values. The large length of the membrane fibers also affects the fixing and locking of the membrane fiber clamps. The proposed device involves pulling the membrane fibers out from the outside of the feeding roller, winding them around three sets of arc grooves, and then wrapping them around the winding roller. At this point, a locking cylinder drives a locking rod to extend into the locking opening, fixing the feeding roller and winding roller. An electric push rod drives a telescopic column to retract into the torsion tube, causing the expansion tiles on the outside of the torsion tube and telescopic column to expand outwards. This results in tension on the membrane fibers outside the expansion tiles. A tension sensor on the output rod of the electric push rod calculates the membrane fiber tension, achieving the effect of batch testing of membrane fiber tensile strength. However, this application has a complex structure, requiring extensive modifications to existing membrane fiber winding or production equipment, making it cumbersome to use. Furthermore, adjusting different membrane fiber spacings is also difficult, and numerical observation is not intuitive. Further improvements are possible.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0019] (1) This utility model adopts a top wheel, a base, an electric cylinder and a cross frame. When detecting the tension of the ultrafiltration membrane fibers, this device can be set up on the outside of the membrane fibers. Then, the top wheel is aligned with the moving membrane fibers. Then, the electric cylinder is activated to shorten, which drives the cross frame and the top wheel to move down. The top wheel rolls and abuts against the membrane fibers, and pushes the membrane fibers to move down and deform, forming an angle with the top wheel. The tension inside the membrane fibers will form a squeezing force on the top wheel. The resultant force is transmitted to the pressure sensor through the wheel frame, and the pressure value can be displayed on the pressure display.

A guide rod 13 is slidably connected through the surface of the hanging plate 7, and a wheel frame 8 is fixedly installed on the bottom surface of the guide rod 13. A top wheel 9 is rotatably connected to the inner side of the wheel frame 8. A pressure sensor 11 is fixedly installed on the top surface of the wheel frame 8 between the wheel frame 8 and the hanging plate 7. A pressure display 12 is installed inside the equipment box 10. The device is used to detect the tension of the ultrafiltration membrane fibers. During tension testing, this device can be set up on the outside of the membrane fiber. Then, the top wheel 9 is aligned with the moving membrane fiber. Subsequently, the electric cylinder 2 is shortened, which drives the cross frame 3 and the top wheel 9 to move downward. The top wheel 9 rolls and comes into contact with the membrane fiber, pushing the membrane fiber downward and deforming it, forming an angle with the top wheel 9. The internal tension of the membrane fiber will generate a compressive force on the top wheel 9. The resultant force is transmitted to the pressure sensor 11 through the wheel frame 8, and the pressure value can be displayed on the pressure display 12. The pressure value is positively correlated with the tension, so the membrane fiber tension can be calculated. This device has a simple structure, can perform simultaneous tension testing on multiple sets of membrane fibers in a large batch, has strong mobility, and high working efficiency. Moreover, this device does not require modification of existing equipment and can be quickly deployed simply by setting it up on the outside of the membrane fiber, making it more practical.

[0031] In one embodiment, multiple sets of guide rods 13 are arranged, and a limiting plate 14 is fixedly installed on the surface of the guide rods 13. The distance between the bottom surface of the limiting plate 14 and the top surface of the wheel frame 8 is equal to the sum of the heights of the hanging plate 7 and the pressure sensor 11. The output end of the pressure sensor 11 abuts against the bottom surface of the hanging plate 7. The guide rods 13 do not affect the slight upward movement of the wheel frame 8. At the same time, the wheel frame 8 is prevented from falling, and the pressure sensor 11 is convenient for pressure detection.

[0032] In one embodiment, a handle bolt 5 is threaded through the top surface of the sleeve 4, and the bottom surface of the handle bolt 5 abuts against the top surface of the crossbeam 3. The operator can loosen the handle bolt 5 and then adjust the position of the sleeve 4 along the crossbeam 3, thereby adjusting the spacing of the top wheel 9. This is suitable for use with membrane filaments of various spacings, enhancing its versatility and applicability, and further improving the convenience of use and work efficiency.

[0033] In one embodiment, the top wheel 9 is rotatably connected to the wheel frame 8 via a wheel axle, and the surface of the top wheel 9 is provided with a wire groove, which facilitates the positioning of the membrane filaments.

[0034] In one embodiment, the surface of the top roller 9 is polished, and multiple sets of top rollers 9 are arranged to reduce wear on the membrane fibers and protect the membrane fibers.

[0035] In one embodiment, the electric cylinder 2 operates synchronously via a synchronization controller, facilitating the stable lifting and lowering of the crossbeam 3.

[0036] In one embodiment, the crossbar 3 adopts a rectangular rod structure to prevent the sleeve 4 from flipping over.

[0037] Working principle:

[0038] When testing the tension of ultrafiltration membrane fibers, this device can be set up outside the membrane fibers. Then, the top wheel 9 is aligned with the moving membrane fibers. Subsequently, the electric cylinder 2 is shortened, driving the crossbeam 3 and the top wheel 9 to move downward. The top wheel 9 rolls and contacts the membrane fibers, pushing the membrane fibers downward and deforming them, forming an angle with the top wheel 9. The internal tension of the membrane fibers will generate a compressive force on the top wheel 9. The resultant force is transmitted to the pressure sensor 11 through the wheel frame 8, and the pressure value can be displayed on the pressure display 12. The pressure value is positively correlated with the tension, so the membrane fiber tension can be calculated. This device has a simple structure, can perform simultaneous tension testing on multiple sets of membrane fibers in a large batch, has strong mobility, and high working efficiency. Moreover, this device does not require modification of existing equipment; it can be quickly deployed simply by setting it up outside the membrane fibers, making it more practical. At the same time, the operator can loosen the handle bolt 5 and adjust the position of the sleeve 4 along the crossbeam 3, thereby adjusting the spacing of the top wheel 9. It is suitable for use with membrane fibers of various spacings, enhancing its versatility and applicability, and further improving the convenience and efficiency of use.
