A lithium sulfate solution concentration detection device

Abstract

This invention discloses a lithium sulfate solution concentration detection device, belonging to the field of detection equipment technology. It includes a base with a pushing component at its upper end, which quantitatively dispenses lithium sulfate solution to a designated location. In this lithium sulfate solution concentration detection device, when the movable rod drives the push block to retract inward, it squeezes a sphere, causing the sphere to move upward and separate from the ring, creating a gap between them to facilitate the entry of lithium sulfate solution into the through-hole. When the movable rod drives the push block to push outward, it moves away from the sphere, and the elastic element pushes the pressing plate downward, squeezing the sphere tightly against the ring, thus sealing the cylinder. This ensures a stable flow rate and avoids flow fluctuations affecting the final product or experimental results, thereby improving the accuracy and reliability of lithium sulfate solution detection.

Description

Technical Field

[0001] This invention relates to detection equipment technology, specifically to a lithium sulfate solution concentration detection device. Background Technology

[0002] Lithium sulfate is a chemical with the molecular formula Li₂SO₄ and a molecular weight of 109.94. It appears as colorless monoclinic crystals or a white crystalline powder, soluble in water but insoluble in acetone and anhydrous ethanol.

[0003] When performing solution testing, the solution sample to be tested can be placed inside the testing container. Then, the detection probe of the detector is inserted through the detection port of the container and extended to a position below the liquid surface. The concentration value of the solution can be obtained by reading the reading on the surface of the detector.

[0004] Chinese invention patent CN115541822A discloses a vehicle urea solution concentration detection device. In this device, the urea solution to be tested is injected into multiple detection cylinders during concentration detection. A piston pad receives and seals the urea solution from the bottom. After the concentration detector detects the urea solution, an active plate rises, causing the piston pad to rise and push the urea solution out from the top of the detection cylinder. The outflowing urea solution falls onto an electronic control mechanism. A first drive motor drives a brush to rotate, cleaning the inner wall of the detection cylinder while the cleaning shaft rises. A second drive motor drives a disc brush to clean the upper surface of the piston pad at the top of the cleaning cylinder. This cleans the detection cylinder and piston pad of any residual urea solution, preventing it from affecting the results of subsequent batches or even multiple batches of tests, thus greatly improving the accuracy of the detection.

[0005] Before testing, impurities in existing lithium sulfate solutions can easily affect the overall test results in subsequent tests. Furthermore, the inhomogeneity of the sample can lead to inaccurate measurement results and abnormal conditions during testing. In addition, it is impossible to ensure that a stable flow rate can be maintained, which can easily affect the final product or experimental results due to flow rate fluctuations. Therefore, a lithium sulfate solution concentration detection device was developed. Summary of the Invention

[0011] A cylinder is provided at the middle position of the upper end of the fixed block. A support plate is provided at the upper end of the inner cavity of the cylinder. A telescopic rod is slidably installed on the inner wall of the support plate. A pressing plate is provided at the lower end of the telescopic rod. An elastic element is sleeved on the outer surface of the telescopic rod. One end of the elastic element is connected to the support plate, and the other end is connected to the pressing plate.

[0012] A ring is provided at the lower end of the inner cavity of the cylinder, and a sphere is provided in the inner cavity of the cylinder between the ring and the pressing plate. The inner cavity of the cylinder is connected to the two through holes.

[0013] A screening assembly, which is mounted at the end of the fixed block, is used to screen the discharged lithium sulfate solution.

[0014] As a further optimization of the present invention, the end of the fixed block is provided with a discharge pipe, and the inner wall of the discharge pipe is in contact with the inner wall of the screening component.

[0015] As a further optimization of the present invention, the screening component includes a grid plate connected to the outlet pipe, and a bottom plate is provided at the end of the grid plate. Multiple sets of support rods are provided at the upper part of the bottom plate and near the edge, and the multiple sets of support rods are evenly distributed at the upper end of the bottom plate.

[0016] As a further optimization of the present invention, a disk is provided at the upper end of the support rod, and multiple sets of slots are opened at the upper end of the disk, and the multiple sets of slots are evenly distributed at the upper end of the disk. At the same time, a connecting block corresponding to the slots is provided on the outer surface of the disk.

[0017] As a further optimization of the present invention, a power component is provided in the middle of the upper end of the base plate, the output end of the power component extends through and to the outside of the disk, and an adjustment plate is provided at the output end of the power component.

[0018] As a further optimization of the present invention, the outer surface of the adjusting plate is provided with a protrusion corresponding to the slot, and a limit rod is rotatably installed at the end of the protrusion, and the outer surface of the limit rod is slidably connected to the inner wall of the slot.

[0019] As a further optimization of the present invention, an adjusting rod is rotatably mounted on the lower end of the limiting rod, and a scraper is rotatably mounted on the lower end of the adjusting rod, the scraper having a fan-shaped cross-section.

[0020] As a further optimization of the present invention, a positioning rod is slidably mounted on the outer surface of the upper end of the scraper, and the end of the positioning rod is connected to the outer surface of the base plate.

[0021] As a further optimization of the present invention, a drive rod is rotatably mounted on the lower end of the limiting rod, and the outer surface of the drive rod is rotatably connected to the end of the connecting block.

[0022] As a further optimization of the present invention, an arc-shaped plate is rotatably mounted on the end of the drive rod, and the lower end of the arc-shaped plate is slidably connected to the upper end of the grid plate.

[0023] Compared with the prior art, the lithium sulfate solution concentration detection device provided by the present invention has the following beneficial effects: When the movable rod drives the push block to retract inward, it squeezes the ball, causing the ball to move upward, thereby separating the ball from the ring and creating a gap between the ring and the ball, which facilitates the lithium sulfate solution to enter the through hole. When the movable rod drives the push block to push outward, it moves away from the ball, and the force of the elastic element pushes the pressing plate downward, squeezing the ball so that it fits tightly against the ring, thereby sealing the cylinder and ensuring that a stable flow rate can be maintained. This avoids the impact of flow rate fluctuations on the final product or experimental results, thereby improving the accuracy and reliability of lithium sulfate solution detection.

[0024] When the limiting rod moves, it synchronously drives the adjusting rod to move as well. Since the lower end of the adjusting rod is rotatably connected to the scraper, and the upper end of the scraper is slidably connected to the positioning rod, the scraper, driven by the adjusting rod, can scrape the end of the grid plate, thus removing particulate matter from the lithium sulfate solution and preventing its accumulation on the grid plate. Simultaneously, the moving limiting rod also drives the driving rod to move, causing it to rotate around the connecting block. This drives the arc-shaped plate rotatably mounted on the driving rod to move, accelerating the flow rate of the lithium sulfate solution and preventing clogging of the grid plate. This significantly improves the filtration accuracy during lithium sulfate solution detection, reduces interference, and enhances the reliability of the final measurement results.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Example: Please refer to Figures 1-8 A lithium sulfate solution concentration detection device includes a base 1, and a pushing component 2 is provided at the upper end of the base 1 to quantitatively dispense lithium sulfate solution at a designated position.

[0039] In this solution, the lithium sulfate solution is quantitatively delivered through the pusher component 2, ensuring that the whole system is in a stable state during detection and that the sample is not homogeneous. This ensures that the measurement results remain accurate and that a stable flow rate is maintained during detection, avoiding the impact of flow rate fluctuations on the final product or experimental results.

[0040] Furthermore, the push component 2 includes a drive component 21, the output end of the drive component 21 is provided with a crankshaft 22, the upper end of the base 1 and located on one side of the drive component 21 is provided with a support block 11, the upper end of the support block 11 is rotatably connected to the outer surface of the crankshaft 22, and two push rods 23 are provided on the outer surface of two adjacent protrusions of the crankshaft 22.

[0041] In this embodiment, the drive unit 21 is a device with power output such as a motor, and is connected to an external control device. When the drive unit 21 is started, it synchronously drives the crankshaft 22 set at its output end to rotate. When the crankshaft 22 rotates, it drives the push rod 23 rotatably mounted on its outer surface to extend and retract.

[0042] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0043] Furthermore, a movable block 24 is rotatably mounted on the end of the push rod 23 away from the crankshaft 22, and a movable rod 25 is rotatably mounted on the end of the movable block 24. At the same time, a push block 251 is provided on the end of the movable rod 25 away from the movable block 24.

[0044] Specifically, when the push rod 23 moves, it synchronously drives the movable block 24 at its end to move. Since the end of the movable block 24 is rotatably connected to the movable rod 25, the movable rod 25 is driven to reciprocate when the push rod 23 moves.

[0045] Furthermore, a fixing block 26 is provided at the upper end of the base 1 and on the side away from the crankshaft 22. A through hole 27 is symmetrically opened at one end of the fixing block 26, and the inner wall of the through hole 27 is slidably connected to the outer surface of the push block 251.

[0046] Specifically, the through hole 27 is used to transport the lithium sulfate solution, so that the lithium sulfate solution will not leak during transportation.

[0047] Furthermore, a cylinder 28 is provided at the middle position of the upper end of the fixing block 26, a support plate 281 is provided at the upper end of the inner cavity of the cylinder 28, a telescopic rod 282 is slidably installed on the inner wall of the support plate 281, a pressing plate 284 is provided at the lower end of the telescopic rod 282, and an elastic element 283 is sleeved on the outer surface of the telescopic rod 282, with one end of the elastic element 283 connected to the support plate 281 and the other end connected to the pressing plate 284.

[0048] Specifically, the elastic element 283 is a spring or other elastic component, which is used to support the pressing plate 284 so that the pressing plate 284 is always in a stable state.

[0049] Furthermore, a ring 286 is provided at the lower end of the inner cavity of the cylinder 28, and a ball 285 is provided in the inner cavity of the cylinder 28 between the ring 286 and the pressing plate 284. The inner cavity of the cylinder 28 is connected to two through holes 27.

[0050] Specifically, when the movable rod 25 drives the push block 251 to retract inward, it squeezes the ball 285, causing the ball 285 to move upward, thereby separating the ball 285 from the ring 286 and creating a gap between the ring 286 and the ball 285, which facilitates the entry of lithium sulfate solution into the through hole 27. When the movable rod 25 drives the push block 251 to push outward, it moves away from the ball 285, and the force of the elastic element 283 pushes the pressing plate 284 downward, squeezing the ball 285 so that it fits tightly against the ring 286. The outer surface of the ball 285 is covered with a sealing component such as rubber.

[0051] Furthermore, the end of the fixing block 26 is provided with an outlet pipe 29, and the inner wall of the outlet pipe 29 is in contact with the inner wall of the screening component 3.

[0052] Specifically, the screening component 3 is constrained by the outlet pipe 29 to ensure that the screening component 3 remains stable as a whole during use.

[0053] Furthermore, the screening component 3, which is assembled at the end of the fixing block 26, is used to screen the discharged lithium sulfate solution. The screening component 3 includes a grid plate 31 connected to the discharge pipe 29, and a base plate 32 is provided at the end of the grid plate 31. Multiple sets of support rods 33 are provided at the upper end of the base plate 32 near the edge, and the multiple sets of support rods 33 are evenly distributed at the upper end of the base plate 32.

[0054] In this embodiment, the outer surface of the mesh plate 31 is snapped onto the inner wall of the outlet pipe 29, thereby facilitating the subsequent disassembly of the mesh plate 31. Simultaneously, a connecting block is provided in the middle portion of the mesh plate 31, and the connecting block is fixedly connected to the base plate 32. The cross-section of the mesh surface on the mesh plate 31 is annular.

[0055] Furthermore, a disc 35 is provided at the upper end of the support rod 33. Multiple sets of slots 351 are formed at the upper end of the disc 35, and these slots 351 are evenly distributed across the upper end of the disc 35. Connecting blocks 352 corresponding to the slots 351 are provided on the outer surface of the disc 35. A power component 34 is provided in the middle of the upper end of the base plate 32. The output end of the power component 34 passes through and extends to the outside of the disc 35, and an adjustment plate 36 is provided at the output end of the power component 34.

[0056] Specifically, the power component 34 is a telescopic rod or other device with telescopic function, and is connected to an external control device. When the power component 34 is started, it synchronously drives the adjustment plate 36 set at its output end to move.

[0057] Furthermore, the outer surface of the adjusting plate 36 is provided with a protrusion 361 corresponding to the slot 351, and a limit rod 37 is rotatably installed at the end of the protrusion 361. The outer surface of the limit rod 37 is slidably connected to the inner wall of the slot 351.

[0058] Specifically, when the adjusting plate 36 moves, the protrusion 361 simultaneously drives the limiting rod 37 to move. The outer surface of the limiting rod 37 is slidably connected to the inner wall of the slot 351, which limits the limiting rod 37 and prevents it from deviating from the set trajectory when moving.

[0059] Furthermore, an adjusting rod 371 is rotatably mounted on the lower end of the limiting rod 37, and a scraper 372 is rotatably mounted on the lower end of the adjusting rod 371. The cross-section of the scraper 372 is fan-shaped. A positioning rod 373 is slidably mounted on the outer surface of the upper end of the scraper 372, and the end of the positioning rod 373 is connected to the outer surface of the base plate 32.

[0060] Specifically, when the limiting rod 37 moves, it synchronously drives the adjusting rod 371 to move. Since the lower end of the adjusting rod 371 is rotatably connected to the scraper 372 and the upper end of the scraper 372 is slidably connected to the positioning rod 373, the end of the grid plate 31 can be scraped when the adjusting rod 371 drives the scraper 372 to move, thereby scraping off the particulate matter in the lithium sulfate solution and preventing it from accumulating on the grid plate 31.

[0061] Furthermore, a drive rod 38 is rotatably mounted on the lower end of the limiting rod 37, and the outer surface of the drive rod 38 is rotatably connected to the end of the connecting block 352. An arc-shaped plate 39 is rotatably mounted on the end of the drive rod 38, and the lower end of the arc-shaped plate 39 is slidably connected to the upper end of the mesh plate 31.

[0062] Specifically, when the limit rod 37 moves, it synchronously drives the drive rod 38 to move, causing the drive rod 38 to rotate around the connecting block 352, thereby driving the arc plate 39 rotatably mounted on the drive rod 38 to move, thereby accelerating the flow rate of the lithium sulfate solution and avoiding clogging of the grid plate 31. This can significantly improve the filtration accuracy in the lithium sulfate solution detection process, reduce interference, and improve the reliability of the final measurement results.

[0063] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
