Description

Technical Field

[0001] The invention relates to the technical field of molecular sieve research and development testing, and in particular to testing equipment for electrolyte dehydration molecular sieves. Background Art

[0002] The electrolyte is an important component of the battery, and it plays a key role in ion conduction. However, the electrolyte often contains a certain amount of impurities and moisture, which will affect the purity and stability of the electrolyte, thereby reducing the performance of the battery. Therefore, it is necessary to add a dehydrated molecular sieve inside the battery to adsorb and separate the impurities and moisture in the electrolyte, thereby improving the purity and stability of the electrolyte, which helps to reduce the energy loss of the battery during the charging and discharging process, and improve the energy density and cycle life of the battery.

[0003] In the process of developing dehydrated molecular sieves, it is necessary to use testing equipment such as specific surface area porosity analyzer to test the dehydrated molecular sieves to ensure that the dehydrated molecular sieves with the best use effect are developed. The specific surface area porosity analyzer determines the specific surface area and pore size distribution of the sample by measuring the amount of gas adsorbed on the sample surface, so that researchers can understand the adsorption capacity, pore structure and transmission properties of the dehydrated molecular sieve, evaluate the adsorption performance of different dehydrated molecular sieves, and screen out the molecular sieve material with the best performance, which helps to optimize the preparation process of the battery and improve the performance and safety of the battery.

[0004] As in the prior art, a patent with a patent authorization announcement number of CN216525341U discloses a specific surface area analyzer with a background test function, including a shell, the outer wall of the shell is fixedly connected to two adsorption tubes, the ends of the two adsorption tubes are detachably connected to the sample tube and the test tube, respectively, the inner wall of the shell is symmetrically rotatably connected to two screws, the outer walls of the two screws are fixedly sleeved with pulleys, the two pulleys are connected by belt transmission, the outer walls of the screws are matched with nuts, and a motor is arranged inside the shell; when the above device is in use, the Dewar flask is placed on the support plate, and the bottle mouth of the Dewar flask is aligned with the sample tube and the test tube, and then the motor is started, and the transmission connection of the two pulleys can be used to drive the two screws to rotate simultaneously, and then the two nuts drive the support plate to move upward through the connecting rod, so that the bottom ends of the sample tube and the test tube are inserted into the liquid nitrogen in the Dewar flask, without the use of a pad, and it is more convenient and quick to use.

[0005] However, the above test equipment still has certain defects when used: During use of the above-mentioned test equipment, a shielding cover is required to cover the Dewar flask and the sample tube to ensure that the test area is not disturbed by the outside world and to protect key components such as the Dewar flask and the sample tube. The existing shielding cover cannot completely cover the bottom of the Dewar flask and can only protect the top of the Dewar flask and the sample tube. This may affect the accuracy of the test results and make it impossible to accurately evaluate the performance of the dehydrated molecular sieve. In addition, during the test, the fixed rod is prone to collide with the fixed column under the rebound force of the coil spring, causing the analyzer to shake and the substance in the Dewar flask to overflow, affecting the accuracy of the test results. When the shielding belt undergoes a small displacement due to bulging or wrinkling, it is difficult for the staff to discover it in time, which greatly reduces the protective effect of the shielding belt and affects the accuracy of the test results.

[0021] The test equipment for electrolyte dehydration molecular sieves of the present invention, when testing, puts the dehydrated molecular sieve sample into a pre-prepared sample tube, then installs the sample tube on the upper part of the analyzer body 1, then pours liquid nitrogen into the Dewar flask 28, and moves the Dewar flask 28 to the placement plate 32, so that the bottle mouth of the Dewar flask 28 is aligned with the sample tube, and then the researcher pulls the two fixing rods 8. Since the fixing rods 8 are fixedly connected to one end of the shielding belt 7, pulling the fixing rods 8 will drive the shielding belt 7 to unfold from the reel 5, and the two shielding belts 7 can thus The Dewar flask 28 completely covers the sample to form a closed shielding space, realizing comprehensive protection of the test area. Then the researchers start the analyzer body 1. At this time, the lifting mechanism in the analyzer body 1 will lift the placement plate 32, driving the Dewar flask 28 to rise, so that the sample tube is immersed in liquid nitrogen, and then the test of the dehydrated molecular sieve begins; through the changes in the pressure in the sample tube and the gas adsorption amount, the analyzer body 1 can draw an adsorption isotherm on the connected computer terminal. By observing the adsorption isotherm, the researchers can evaluate the performance of the dehydrated molecular sieve; When the test is completed, the lifting mechanism in the analyzer body 1 will lower the placement plate 32, driving the Dewar flask 28 to descend. When the placement plate 32 descends to the placement table 2, the analyzer body 1 stops running, and then the researcher can loosen the fixing rod 8. At this time, the elastic force of the coil spring 10 drives the reel 5 to rotate, thereby retracting the shielding tape 7 into the reel slot 6 for the next use; The analyzer is internally provided with a control component, which includes a monitoring module, an analysis module and a regulation module; Electric push rods and rubber blocks are arranged at the positions of the inner wall of the slide groove 12 on both sides of the outer wall of the fixed rod 8, and the electric push rods and the fixed rod 8 are kept in a vertical state; during the unfolding of the shielding belt 7, the monitoring module monitors the displacement data of the coil springs 10 on both sides.

The impact caused by the collision affects the stability of the Dewar flask 28. The impact time of the collision process is The average impact force on the reel at the moment of impact is According to the momentum theorem, the initial momentum of the reel is , the momentum becomes 0 after the collision, then , derive ; The friction between the rubber block and the slide 12 , is the friction coefficient between the rubber block and the slide 12, is the positive pressure exerted by the electric push rod on the rubber block. , through multiple tests to obtain the coefficient of the electric push rod , and They are the length data of the electric push rod after change and at the beginning; according to Newton's second law ( Understanding friction , is the acceleration of the fixed rod 8), the fixed rod 8 decelerates under the action of friction, and the initial speed is , its speed Over time The change relationship is: That is, the moving speed of the fixing rod 8 is adjusted by changing the length of the electric push rod, so that the fixing rod 8 will not collide with the fixing column 4. ,Right now ,but ; The shielding tape 7 is made of dark brown, which can not only effectively reduce the reflection and refraction of light, thereby minimizing the interference of light on the test area, ensuring the darkroom conditions of the test environment, and improving the accuracy and reliability of the test data, but also the shielding tape 7 is made of a special polyester fiber material with high strength, wear resistance, corrosion resistance and flexibility. The material has good mechanical strength and chemical stability, and can be used for a long time without breaking or deformation, thereby ensuring the reliability and durability of the shielding tape 7. The material also has good flexibility, can be easily rolled and unfolded, and can better fit the Dewar flask 28 and the sample to form effective shielding protection. The special polyester fiber material itself has a certain light absorption, which, combined with the dark brown color, further enhances the absorption of light and improves the shielding effect. At the same time, the material also has good anti-static properties, which can prevent static electricity accumulation, thereby reducing the influence of static electricity discharge on the test results. The retractable shielding structure provided by the present invention can effectively isolate external interference, thereby significantly improving the accuracy and reliability of test data, ensuring the scientificity and effectiveness of the test results, and helping to maintain the stability of environmental parameters such as temperature and humidity in the test area. Compared with the existing technology, a tighter covering of the test area is achieved, thereby significantly improving the accuracy and reliability of test data, ensuring that researchers can accurately evaluate the performance of dehydrated molecular sieves, and helping to assist researchers in the research and development of dehydrated molecular sieves.

[0022] It is worth noting that, for those skilled in the art, other structures of the analyzer body 1 and its working principles, such as the lifting mechanism, etc., can be understood and implemented, so they are not described in detail in the present invention.

[0023] As a preferred technical solution of the present invention, the two shielding belts 7 are fixedly connected to the upper and lower sides with positioning belts 13, the outer wall of each positioning belt 13 is slidably connected to the slide rail 11, the surface of the placement table 2 is provided with a fixed groove 31 corresponding to the position of the slide rail 11, the other slide rail 11 is fixedly connected to the analyzer body 1, each slide rail 11 is provided with a slide groove 12 corresponding to the position of the positioning belt 13, and the upper and lower ends of the two fixed rods 8 are connected with positioning components.

[0024] Specifically, the positioning belt 13 and the slide groove 12 can limit the deployment path of the shielding belt 7, prevent the shielding belt 7 from deformation, guide and fix the shielding belt 7, ensure that the shielding belt 7 can maintain the correct position and shape during the deployment and retraction process, so that the shielding belt 7 can move smoothly during deployment and retraction, avoiding inaccurate positioning caused by shaking or offset; After the fixing rods 8 on the two shielding belts 7 are in contact with each other, the image data of the shielding belt 7 is acquired, and the acquired image data is gray-processed, and the gray-processed image is divided into image blocks according to the pixel block size, and the gray value of each image block is recorded; the image block is marked according to the number of rows and columns on the gray-processed image, which is recorded as , Indicates Line The grayscale difference of adjacent image blocks is calculated. If the grayscale difference is greater than a preset grayscale threshold, it is determined that an abnormality exists in the corresponding area of ​​the image block; the position mark of the image block marked as abnormal is recorded, and then the size of the position mark is compared. The image blocks with the same number of rows and the same number of columns as 1 or the same number of rows as 1 and the same number of columns in the position mark are determined to be adjacent. The continuous number of adjacent image blocks is recorded and recorded as the row continuous number and the column continuous number according to the number of rows and columns, respectively; if the row continuous number is the same as the column continuous number and is greater than the preset row threshold or the preset column threshold, it is determined that there is a bulge on the shielding belt 7, an adjustment warning signal is generated, and the adjustment warning signal is transmitted to the adjustment module; if only one of the row continuous number and the column continuous number is greater than the corresponding preset threshold and the other is less than the corresponding preset threshold, it is determined that there is a wrinkle on the shielding belt 7, an adjustment warning signal is generated, and the adjustment warning signal is transmitted to the adjustment module.

[0025] As a preferred technical solution of the present invention, the positioning assembly includes a positioning block 14, a connecting plate 15, a rotating rod 16 and a rotating sleeve 17. Each fixed rod 8 is fixedly connected to a positioning block 14 at both ends, each positioning block 14 is fitted with the inner wall of the slide groove 12, each positioning block 14 is fixedly connected to a connecting plate 15 on one side outside the slide groove 12, each connecting plate 15 is fixedly connected to a rotating rod 16 on one side, each rotating rod 16 is rotatably connected to a rotating sleeve 17 on the outer wall, and each rotating sleeve 17 is fitted with the outer wall of the slide rail 11.

[0026] Specifically, when the researchers pull the shielding belt 7 through the fixed rod 8, the positioning block 14 and the rotating sleeve 17 will slide closely against the side wall of the slide rail 11. At this time, the positioning block 14 and the rotating sleeve 17 can ensure that the positioning belt 13 moves stably in the slide groove 12 to prevent the positioning belt 13 from shifting, thereby further ensuring the stability of the shielding belt 7 during the unfolding process; the combination of the connecting plate 15, the rotating rod 16 and the rotating sleeve 17 can make the fixed rod 8 smoother during the pulling process, avoiding jamming or friction, thereby further improving the stability and reliability of the shielding structure, facilitating the winding and unfolding of the shielding belt 7, and reducing the difficulty of operation.

[0027] As a preferred technical solution of the present invention, two connecting ropes 33 are fixedly connected to the bottom surface of the placement plate 32, and a fixed block 34 is fixedly connected to the surface of the placement table 2. Sliding grooves 35 are opened on both sides of the fixed block 34, and a limiting rod 36 is fixedly connected in each sliding groove 35. The bottom end of the connecting rope 33 passes through between the inner wall of the sliding groove 35 and the limiting rod 36, and passes out along the lower side of the limiting rod 36. A movable plate 37 is fixedly connected to the side of the bottom of the fixed rod 8 away from the connecting plate 15, and a movable rod 38 is fixedly connected to the bottom of the movable plate 37. The bottom end of the connecting rope 33 is sleeved on the middle part of the movable rod 38.

[0028] Specifically, after placing the Dewar flask 28 on the placement plate 32, the researcher starts the analyzer body 1. At this time, the lifting mechanism in the analyzer body 1 will drive the placement plate 32 to rise, and then lift the Dewar flask 28 up. The placement plate 32 will pull the connecting rope 33. Through the guiding effect of the limit rod 36, the connecting rope 33 will then pull the moving rod 38 and the moving plate 37 to move along the outer wall of the slide rail 11. The moving plate 37 will then pull the fixed rod 8 to automatically unfold the shielding belt 7. When the placement plate 32 rises to the highest point, the shielding belt 7 will be fully unfolded, and the analyzer body 1 can continue to carry out subsequent testing work; after the test is completed, the placement plate 32 will drive the Dewar flask 28 to move downward. At this time, the connecting rope 33 will be in a relaxed state. Under the pulling force of the coil spring 10, the shielding belt 7 will be rolled up to the outer wall of the winding shaft 5 to facilitate the next test work; By utilizing this automated and intelligent shielding tape 7 unfolding and reeling mechanism, researchers can focus more on the test process itself without spending too much time on the operation of the shielding tape 7, thereby greatly improving the test efficiency.

[0029] As a preferred technical solution of the present invention, handles 19 are fixedly connected to the middle parts of the two fixing rods 8 .

[0030] Specifically, by applying force through the handle 19, researchers can manually pull the fixing rod 8. When the automatic deployment mechanism fails, the handle 19 can also be used as a temporary backup plan for manually deploying the shielding belt 7 to ensure the smooth progress of the test work.

[0031] As a preferred technical solution of the present invention, a support rod 20 is fixedly connected to the middle part of one handle 19, and a connecting block 21 is rotatably connected to the outer wall of the support rod 20. A limiting groove 22 corresponding to the position of the connecting block 21 is opened in the middle part of the other handle 19, and one end of the connecting block 21 away from the support rod 20 is fixedly connected to a limiting block 23, and the limiting block 23 is in contact with the outer wall of the handle 19.

[0032] Specifically, when the shielding belt 7 is unfolded, the two fixing rods 8 will fit together. At this time, the researcher rotates the connecting block 21 so that the connecting block 21 is engaged with the limiting groove 22. At this time, under the obstruction of the limiting block 23, the two handles 19 will be engaged together, thereby realizing the connection between the two fixing rods 8 and forming a stable locking state. This locking state ensures that the two shielding belts 7 will not move or loosen due to external force or vibration after unfolding, further improving the stability and reliability of the shielding effect, thereby ensuring that the test area is always in a closed and stable protection state.

[0033] As a preferred technical solution of the present invention, the inner sides of the two handles 19 are fixedly connected with a rotating shaft 24, the outer walls of the two rotating shafts 24 are rotatably connected with a rotating plate 25, the two rotating plates 25 are fixedly connected with a clamping plate 26 on the side away from the rotating shaft 24, and one side of the two fixed rods 8 is provided with a clamping groove 27 corresponding to the position of the clamping plate 26.

[0034] Specifically, when the researcher pulls open the shielding tape 7, he holds the handle 19, and at this time, the researcher's fingers will squeeze the rotating plate 25, so that the rotating plate 25 is separated from the handle 19, and the center of the handle 19 is transformed into a state, and the researcher can hold the handle 19 and pull the fixed rod 8 to unfold the shielding tape 7; when it is necessary to retract the shielding tape 7, the researcher pushes the handle 19 from the other side of the handle 19, and at this time, the rotating plate 25 will fill the vacancy in the center of the handle 19, and under the action of the clamping plate 26 and the clamping groove 27, the rotating plate 25 cannot rotate, and at this time, the researcher can use his hand to push the rotating plate 25 to move, thereby pushing the fixed rod 8 to move and reeling the shielding tape 7; through this The arrangement enables the handle 19 to serve as both a force-bearing component for pulling open the shielding belt 7 and a pushing component for retracting the shielding belt 7, thereby realizing functional integration and unification, reducing the number of components, simplifying the structure, and also improving the convenience and fluency of operation, making the entire shielding mechanism more intelligent and user-friendly, and more in line with actual application needs. By setting structures such as the rotating shaft 24, the rotating plate 25, the clamping plate 26 and the clamping groove 27, the handle 19 can automatically adjust its state according to operational requirements, which not only facilitates the unfolding and retraction of the shielding belt 7, but also improves the comfort and efficiency of equipment operation, and has good innovation and practicality.

[0035] As a preferred technical solution of the present invention, a magnetic column 18 is fixedly connected inside the fixing rod 8 .

[0036] Specifically, when the two fixing rods 8 are fitted together, the magnetic column 18 can adsorb the two fixing rods 8 together, thereby ensuring that the two fixing rods 8 remain in close contact, preventing the fixing rods 8 from shaking and causing gaps between the fixing rods 8, and ensuring the stability of the unfolded state of the shielding belt 7.

[0037] As a preferred technical solution of the present invention, a magnetic belt 29 is fixedly connected inside the positioning belt 13, and the slide rail 11 is made of iron material.

[0038] Specifically, the adsorption force between the magnetic belt 29 and the slide rail 11 can ensure that there is no gap between the positioning belt 13 and the slide rail 11, thereby achieving a better covering effect and ensuring that the positioning belt 13 is more stable and smooth during the sliding process.

[0039] As a preferred technical solution of the present invention, the slide rail 11 is in an arc shape, and the side where the positioning block 14 fits with the slide groove 12 is an arc surface.

[0040] Specifically, the slide rail 11 is designed to be an arc shape, which can effectively guide the positioning belt 13 to move along a predetermined arc track, thereby ensuring that the shielding belt 7 can move more smoothly and smoothly during the unfolding and retracting process, avoiding the distortion, folding or jamming that may be caused by linear movement. This arc-shaped design not only reduces the friction between the positioning belt 13 and the slide rail 11, but also makes the movement of the shielding belt 7 more natural and smooth, thereby improving the operating efficiency and service life of the shielding belt 7; the positioning block 14 set on the arc surface can reduce the friction between the positioning block 14 and the arc-shaped inner wall of the slide groove 12, reduce the wear of the positioning block 14 and the slide rail 11, and improve the service life of both.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
