Description

Technical Field

[0001] The invention relates to detection equipment technology, and in particular to a lithium sulfate solution concentration detection device. Background Art

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

[0003] When conducting solution testing, the solution sample to be tested can be placed inside the test tank, and then the detection probe of the detector is used to penetrate the detection port of the tank and extend to the position below the liquid surface. The reading on the surface of the detector can obtain the numerical value of the solution concentration.

[0004] A Chinese invention patent with publication number CN115541822A discloses a device for detecting the concentration of a urea solution for a vehicle. In the device for detecting the concentration of a urea solution for a vehicle, the urea solution to be detected is respectively injected into a plurality of detection cylinders, and a piston pad receives and seals the urea solution from the bottom. After the urea solution is detected by the concentration detector, the active plate rises to drive the piston pad to rise to push the urea solution to flow out from the upper end of the detection cylinder, wherein the outflowing urea solution falls onto the electric control mechanism, the first drive motor drives the cylinder brush to rotate when the driving motor is running, and cleans the inner wall of the detection cylinder while the cleaning shaft rises, and the second drive motor drives the disc brush to clean the upper end surface of the piston pad that rises to the top of the cleaning cylinder, and cleans the residual urea solution on the detection cylinder and the piston pad, so as to prevent the detection results of the next batch or even multiple batches from being affected, thereby greatly improving the accuracy of the detection.

[0005] Before the existing lithium sulfate solution is tested, the impurities inside it are likely to affect the overall test results in subsequent tests. In addition, the sample is non-uniform, and the measurement results may be inaccurate, resulting in abnormal conditions during the test. At the same time, 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 fluctuations. Therefore, a lithium sulfate solution concentration detection device has been developed. Summary of the invention

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention; the terms "first", "second", and "third" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance. In addition, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example: See Figure 1-Figure 8 A lithium sulfate solution concentration detection device includes a base 1, and a pushing component 2 is arranged on the upper end of the base 1. The lithium sulfate solution is quantitatively placed at a designated position through the pushing component 2.

[0025] In this solution, the lithium sulfate solution is quantitatively transported through the push component 2, so that the whole is in a stable state during detection, and the sample is guaranteed to be non-uniform, so that the measurement results remain accurate, and a stable flow rate can be maintained during detection to avoid the final product or experimental results being affected by flow fluctuations.

[0026] Furthermore, the pushing assembly 2 includes a driving member 21, a crankshaft 22 is provided at the output end of the driving member 21, a support block 11 is provided at the upper end of the base 1 and on one side of the driving member 21, 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 surfaces of two adjacent raised portions of the crankshaft 22.

[0027] In this embodiment, the driving member 21 is a device with power output such as a motor, and is connected to an external control device. When the driving member 21 is started, it synchronously drives the crankshaft 22 arranged at its output end to rotate. When the crankshaft 22 rotates, it drives the push rod 23 installed on its outer surface to retract and retract.

[0028] The control device can select a single-chip microcomputer as the control end. In this embodiment, the single-chip microcomputer is a typical embedded microcontroller (Micro controller unit), which is composed of an arithmetic unit, a controller, a memory, an input and output device, etc., which is equivalent to a microcomputer. Compared with the general-purpose microprocessor used in personal computers, it emphasizes self-supply (no external hardware) and cost saving. Its biggest advantage is that it is small in size and can be placed inside the instrument, but it has a small storage capacity, a simple input and output interface, and low functional consumption.

[0029] Furthermore, a movable block 24 is rotatably mounted on one end of the push rod 23 away from the crankshaft 22 , a movable rod 25 is rotatably mounted on the end of the movable block 24 , and a push block 251 is provided on one end of the movable rod 25 away from the movable block 24 .

[0030] Specifically, when the push rod 23 moves, the movable block 24 disposed at its end is synchronously driven to move. Since the end of the movable block 24 is rotatably connected to the movable rod 25, when the push rod 23 moves, the movable rod 25 is driven to reciprocate.

[0031] Furthermore, a fixing block 26 is provided at the upper end of the base 1 and at a side away from the crankshaft 22 , and 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 .

[0032] Specifically, the conducting hole 27 is used to transport the lithium sulfate solution so that the lithium sulfate solution will not leak during transportation.

[0033] Furthermore, a cylinder 28 is provided in the middle position of the upper end of the fixed 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, an elastic member 283 is sleeved on the outer surface of the telescopic rod 282, and one end of the elastic member 283 is connected to the support plate 281, and the other end is connected to the pressing plate 284.

[0034] Specifically, the elastic member 283 is an elastic member such as a spring, which is used to support the pressing plate 284 so that the pressing plate 284 is always in a stable state.

[0035] Furthermore, a ring 286 is disposed at the lower end of the inner cavity of the cylinder 28 , and a sphere 285 is disposed in the inner cavity of the cylinder 28 and between the ring 286 and the pressing plate 284 . The inner cavity of the cylinder 28 is connected to the two conducting holes 27 .

[0036] Specifically, when the movable rod 25 drives the push block 251 to retract inward, the sphere 285 is squeezed, causing the sphere 285 to move upward, thereby separating the sphere 285 from the ring 286, and creating a gap between the ring 286 and the sphere 285, which facilitates the lithium sulfate solution to enter the conductive hole 27. When the movable rod 25 drives the push block 251 to push outward, it moves away from the sphere 285, and the pressure plate 284 is pushed downward by the force of the elastic member 283, and the sphere 285 is squeezed to make it fit tightly on the ring 286, wherein the outer surface of the sphere 285 is provided with a rubber or other sealing component.

[0037] Furthermore, a guide pipe 29 is provided at the end of the fixing block 26 , and the inner wall of the guide pipe 29 is in contact with the inner wall of the screening assembly 3 .

[0038] Specifically, the screening assembly 3 is limited by the outlet pipe 29 to ensure that the screening assembly 3 remains stable as a whole during use.

[0039] Furthermore, the screening assembly 3 is mounted on the end of the fixed block 26 and is used to screen the derived lithium sulfate solution. The screening assembly 3 includes a mesh plate 31 connected to the outlet pipe 29, and a bottom plate 32 is disposed at the end of the mesh plate 31, and a plurality of support rods 33 are disposed at the upper end of the bottom plate 32 and near the edge thereof, and the plurality of support rods 33 are evenly distributed at the upper end of the bottom plate 32.

[0040] In this embodiment, the outer surface of the grid plate 31 is clamped on the inner wall of the outlet pipe 29, so as to facilitate the subsequent disassembly of the grid plate 31. At the same time, a docking block is provided in the middle part of the grid plate 31, and the docking block is fixedly connected to the bottom plate 32, wherein the cross section of the grid surface on the grid plate 31 is annular.

[0041] Furthermore, a disc 35 is provided at the upper end of the support rod 33, and a plurality of slots 351 are provided at the upper end of the disc 35, and the plurality of slots 351 are evenly distributed at the upper end of the disc 35, and a connecting block 352 corresponding to the slots 351 is provided on the outer surface of the disc 35. A power member 34 is provided in the middle of the upper end of the bottom plate 32, and the output end of the power member 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 member 34.

[0042] Specifically, the power member 34 is a device with a telescopic function such as an electric telescopic rod, and is connected to an external control device. When the power member 34 is started, it synchronously drives the adjustment plate 36 arranged at its output end to move.

[0043] Furthermore, a protrusion 361 corresponding to the slot hole 351 is provided on the outer surface of the adjustment plate 36 , and a limit rod 37 is rotatably mounted on the end of the protrusion 361 , and the outer surface of the limit rod 37 is slidably connected to the inner wall of the slot hole 351 .

[0044] Specifically, when the adjustment plate 36 moves, the cooperating protrusion 361 synchronously drives the limit rod 37 to move, wherein the outer surface of the limit rod 37 is slidably connected to the inner wall of the slot 351, and the limit rod 37 is limited at the same time to prevent the limit rod 37 from deviating from the set trajectory when moving.

[0045] 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 bottom plate 32.

[0046] Specifically, when the limit rod 37 moves, the adjusting rod 371 is synchronously driven 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, when the adjusting rod 371 drives the scraper 372 to move, the end of the grid plate 31 can be scraped, thereby scraping off the particulate matter in the lithium sulfate solution to prevent it from accumulating on the grid plate 31.

[0047] Further, the lower end of the limit rod 37 is rotatably mounted with a driving rod 38, and the outer surface of the driving rod 38 is rotatably connected to the end of the connecting block 352. The end of the driving rod 38 is rotatably mounted with an arc plate 39, and the lower end of the arc plate 39 is slidably connected to the upper end of the grid plate 31.

[0048] Specifically, when the limit rod 37 moves, the driving rod 38 is synchronously driven to move, so that the driving rod 38 rotates around the connecting block 352, thereby driving the arc plate 39 rotatably mounted on the driving rod 38 to move, thereby accelerating the flow rate of the lithium sulfate solution, while avoiding clogging the grid plate 31, which can significantly improve the filtration accuracy during the detection of the lithium sulfate solution, reduce interference, and improve the reliability of the final measurement results.

[0049] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
