Description

Technical Field

[0001] This invention relates to the field of fluoride content testing technology, specifically a portable device for detecting the fluoride content of solid waste. Background Technology

[0002] Portable solid waste fluoride content detection is a rapid analytical technique that can be moved to the site and does not require large laboratory equipment. It is used to quickly determine the content of soluble fluoride (leaked fluoride) or total fluoride in solid waste in situ at solid waste dumps, landfills, hazardous waste plants, and smelting slag sites. When performing portable testing of fluoride content in solid waste, the solid waste to be tested is usually ground and mixed with water, filtered to obtain the test solution, and then the electrode is placed in the test solution while the solution is stirred. The fluoride ion concentration in the test solution is read, and the leaching fluoride content of the solid waste is calculated based on the volume of the test solution and the weight of the sample. Since the test solution needs to be stirred during the detection process, the liquid surface around the electrode will fluctuate, which will disturb the ion balance on the electrode surface. This will cause the value to fluctuate continuously during the detection process, affecting the stability of the detection and reducing the detection efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a portable solid waste fluoride content detection device to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a portable device for detecting the fluoride content of solid waste, comprising a main body, a temperature carbon rod detachably connected to the top of the main body, and further comprising: The auxiliary mechanism is located on the side wall of the main body to ensure the stability of the data during the testing process; The auxiliary mechanism includes several fixed blocks installed on the side wall of the main body, and an outer cylinder is fixedly connected to the outer surface of the several fixed blocks; A sliding mechanism is installed inside the outer cylinder to prevent uneven distribution of fluoride ions in the solution. The sliding mechanism includes a hollow ring 1 that is slidably disposed inside the outer cylinder. Several L-plates are fixedly connected to the top of the hollow ring 1, and the several L-plates are arranged in a circular array with the middle part of the hollow ring 1 as the center.

[0005] Furthermore, the main body includes: The detection component, installed on top of the main body, is used to detect the fluoride content in the solution.

[0006] Furthermore, the auxiliary mechanisms also include: The fixing component is installed on the outer surface of the outer cylinder; A rotating assembly is installed at the bottom of the outer cylinder; During the stirring process, the liquid is guided by the fixed component to flow towards the rotating component. When the liquid enters the rotating component, it pushes the rotating component to rotate, which disturbs the liquid between the detection component and the outer cylinder.

[0007] Furthermore, the sliding mechanism also includes: Limiting components are installed on the side wall of hollow ring one; The guide component is installed at the bottom of the limit component; The limiting and guiding components can move out of position after the liquid is disturbed, and reduce the retention of air bubbles on the liquid surface during movement.

[0008] Furthermore, the detection assembly includes a composite electrode detachably connected to the top of the main body, with several rubber plates slidably connected to the outer surface of the composite electrode.

[0009] Furthermore, several rubber plates are arranged in a circular array around the composite electrode, and an inner cylinder is fixedly connected to the outer surface of the rubber plates. Several circular holes are opened on the outer surface of the inner cylinder.

[0010] Furthermore, several fixing blocks are fixedly connected to the outer surface of the inner cylinder; The fixing component includes several circular holes formed on the outer surface of the outer cylinder; The outer surface of the outer cylinder is provided with several spiral grooves; Among them, the first and second circular holes are arranged alternately. During the stirring process, part of the solution will be guided by multiple spiral grooves during rotation, which will suppress the undulation of the liquid surface and provide a spiral downward path for the rotating solution.

[0011] Furthermore, the rotating assembly includes a rotating ring rotatably connected to the bottom of the inner cylinder, and the top outer wall of the rotating ring is provided with several right-angle grooves.

[0012] Furthermore, several right-angled grooves are connected to the outside of the rotating ring, and several inclined plates are fixedly connected to the top of the rotating ring; Several inclined plates are fixedly connected to the inner wall of the rotating ring; Among them, several inclined plates are located in the area between the inner cylinder and the outer cylinder.

[0013] Furthermore, the limiting assembly includes a limiting rod that slides through the side wall of the L-plate; The guide assembly includes a guide ring fixedly connected to the bottom of several limit rods, and a hollow ring is fixedly connected to the inner wall of the guide ring; Several long rods are fixedly connected to the bottom of the guide ring, and several conical cylinders are fixedly connected to the outer surface of the long rods.

[0014] The present invention has the following beneficial effects: 1. In this invention, the solution on the outer surface of the composite electrode flows downward through the gap between the composite electrode and the inner cylinder, ensuring ion exchange between the outer surface of the composite electrode and the stirred solution. In addition, when the solution outside the outer cylinder rotates and flows, the solution flows downward along multiple spiral grooves on its outer surface, thereby suppressing the fluctuation of the liquid surface of the test solution during stirring. This ensures the fluoride ion balance on the surface of the composite electrode, improves the stability of the composite electrode during the detection process, and increases the detection efficiency.

[0015] 2. This invention, by agitating the solution between the inner and outer cylinders, can reduce the difficulty of the solution quickly entering the surface of the inner cylinder and the stagnation of the solution in this area. This ensures that the solution can be fully exchanged on the surface of the composite electrode while maintaining the uniformity of the fluoride ion concentration distribution on the surface of the composite electrode, thereby improving the stability and efficiency of composite electrode detection.

[0016] 3. By reflecting the solution surface to the outside of the outer cylinder, this invention can reduce the occurrence of bubbles rising and remaining on the liquid surface after the solution between the inner and outer cylinders is disturbed and interacts with the solution entering through the second circular hole. By reducing the retention of bubbles on the solution surface, the accuracy of the composite electrode in detecting fluoride ions in the solution can be ensured. At the same time, the continuity of composite electrode detection and the smoothness of the solution flowing to the surface of the composite electrode are improved.

[0017] 4. In this invention, the hollow ring 2, through the flow resistance of the conical cylinder in the solution, causes the hollow ring 1 and hollow ring 2 to gradually overlap as they float downwards, forming a closed annular plate between the outer and inner cylinders. At this time, the closed annular plate floats again at the solution surface, thereby limiting the floating amplitude of the solution between the inner and outer cylinders. This reduces the interference of the solution fluctuations in this area with the solution surface of the composite electrode, further enhancing the stability of the composite electrode during the detection process, and simultaneously improving the detection efficiency of the composite electrode during the detection process.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-8 As shown, the present invention is a portable solid waste fluoride content detection device, including a main body 1, a temperature carbon rod 101 detachably connected to the top of the main body 1, and further including: Auxiliary mechanism 2 is installed on the side wall of the main body 1 to ensure the stability of data during the detection process; The auxiliary mechanism 2 includes several fixing blocks 201 disposed on the side wall of the main body 1, and an outer cylinder 211 is fixedly connected to the outer surface of the several fixing blocks 201; Sliding mechanism 3 is installed inside the outer cylinder 211 to prevent uneven distribution of fluoride ions in the solution; The sliding mechanism 3 includes a hollow ring 301 that is slidably disposed inside the outer cylinder 211. Several L-plates 311 are fixedly connected to the top of the hollow ring 301, and the several L-plates 311 are arranged in a circular array with the middle part of the hollow ring 301 as the center.

[0024] Entity 1 includes: The detection component 11 is installed on the top of the main body 1 and is used to detect the fluoride content in the solution.

[0025] Auxiliary mechanism 2 also includes: Fixing component 21 is disposed on the outer surface of outer cylinder 211; Rotating assembly 22 is installed at the bottom of outer cylinder 211; During the stirring process, the liquid is guided by the fixed component 21 to flow towards the rotating component 22. When the liquid enters the rotating component 22, the liquid pushes the rotating component 22 to rotate, which disturbs the liquid between the detection component 11 and the outer cylinder 211.

[0026] The sliding mechanism 3 also includes: Limiting component 31 is installed on the side wall of hollow ring 301; Guide component 32 is installed at the bottom of limit component 31; The limiting component 31 and the guiding component 32 can move out of position after the liquid is disturbed, and reduce the retention of air bubbles on the liquid surface during the movement.

[0027] The detection component 11 includes a composite electrode 111 detachably connected to the top of the main body 1, and a number of rubber plates 112 are slidably connected to the outer surface of the composite electrode 111.

[0028] A plurality of rubber plates 112 are arranged in a circular array around the composite electrode 111. An inner cylinder 113 is fixedly connected to the outer surface of the plurality of rubber plates 112. A plurality of circular holes are opened on the outer surface of the inner cylinder 113. First, the solid waste to be tested is ground and mixed with pure water in a certain proportion. Then, the mixed liquid is filtered to remove solid residue and obtain the test solution. Next, the temperature carbon rod 101 and the composite electrode 111 are installed on the top of the main body 1. Then, the electrode is placed in the test solution for measurement. At the same time, the test solution is stirred during the measurement process. After the composite electrode 111 detects the fluoride ion concentration in the test solution, the fluoride content in the solid waste is calculated based on the volume of the test solution and the weight of the solid waste.

[0029] Several fixing blocks 201 are fixedly connected to the outer surface of the inner cylinder 113; The fixing component 21 includes several circular holes formed on the outer surface of the outer cylinder 211; The outer surface of the outer cylinder 211 is provided with several spiral grooves 212; Among them, the first and second circular holes are arranged alternately. During the stirring process, part of the solution will be guided by multiple spiral grooves 212 during rotation, which will suppress the undulation of the liquid surface and provide a spiral downward path for the rotating solution.

[0030] The rotating assembly 22 includes a rotating ring 221 rotatably connected to the bottom of the inner cylinder 113, and the top outer wall of the rotating ring 221 is provided with a plurality of right-angle grooves 222; When the test solution, which is rotating and flowing on the outer surface of the outer cylinder 211, flows downward in a spiral under the guidance of multiple spiral grooves 212, the downward flowing liquid will impact multiple right-angle grooves 222, driving the rotating ring 221 to rotate at the bottom of the inner cylinder 113.

[0031] Several right-angled grooves 222 are connected to the outside of the rotating ring 221, and several inclined plates 223 are fixedly connected to the top of the rotating ring 221. Several inclined plates 224 are fixedly connected to the inner wall of the rotating ring 221; Among them, several inclined plates 223 are located in the area between the inner cylinder 113 and the outer cylinder 211; The solution between the inner cylinder 113 and the outer cylinder 211 is disturbed by multiple inclined plates 223. At the same time, when the rotating ring 221 rotates, the rotating ring 221 will accelerate the downward flow speed of the solution between the composite electrode 111 and the inner cylinder 113 through the rotation of multiple inclined plates 224.

[0032] The limiting component 31 includes a limiting rod 312 that slides through the side wall of the L plate 311; The guide assembly 32 includes a guide ring 321 fixedly connected to the bottom of a plurality of limit rods 312, and a hollow ring 322 is fixedly connected to the inner wall of the guide ring 321. The bottom of the guide ring 321 is fixedly connected to several long rods 323, and the outer surface of the long rods 323 is fixedly connected to several conical cylinders; When the hollow ring 2 322 floats upward, it drives multiple long rods 323 to rise synchronously. At this time, the several conical cylinders on the surface of the multiple long rods 323 are in the solution, and the floating amplitude of the hollow ring 2 322 is limited by the resistance of the water. At this time, the hollow ring 2 322 and the hollow ring 1 301 will separate and intertwine with each other as the solution floats.

[0033] In use, the solid waste to be tested is first ground, and pure water is added in proportion and shaken to mix. Then the mixed liquid is filtered to remove solid residue and obtain the test solution. Then the temperature carbon rod 101 and the composite electrode 111 are installed on the top of the main body 1. The electrode is then placed in the test solution for measurement. At the same time, the test solution is stirred during the measurement process. After the composite electrode 111 detects the fluoride ion concentration in the test solution, the fluoride content in the solid waste is calculated based on the volume of the test solution and the weight of the solid waste.

[0034] When the solution to be tested is stirred and rotates, the flow of the solution forms a rotating water flow on the outer surface of the outer cylinder 211, and flows through the second circular hole on the outer cylinder 211 into the inner cylinder 113. Since the second and first circular holes on the outer cylinder 211 and the inner cylinder 113 are arranged alternately, the solution is blocked by the outer wall of the inner cylinder 113 when it flows through the second circular hole into the inner cylinder 113. After changing direction between the inner cylinder 113 and the outer cylinder 211, it can flow through the first circular hole on the inner cylinder 113 to the surface of the composite electrode 111. This process can slow down the flow speed of the solution towards the composite electrode 111 and allow it to pass through at a relatively gentle flow rate. The solution flows from the inner cylinder 113 to the surface of the composite electrode 111, while the solution on the outer surface of the composite electrode 111 flows downward through the gap between the composite electrode 111 and the inner cylinder 113, ensuring ion exchange between the outer surface of the composite electrode 111 and the stirred solution. In addition, when the solution outside the outer cylinder 211 rotates and flows, the solution flows downward along multiple spiral grooves 212 on its outer surface, thereby suppressing the fluctuation of the liquid surface of the test solution during stirring. This ensures the fluoride ion balance on the surface of the composite electrode 111, improves the stability of the composite electrode 111 during the detection process, and increases the detection efficiency.

[0035] When the test solution, which is rotating and flowing on the outer surface of the outer cylinder 211, flows downward in a spiral under the guidance of multiple spiral grooves 212, the downward flowing liquid impacts multiple right-angle grooves 222, driving the rotating ring 221 to rotate at the bottom of the inner cylinder 113. Simultaneously, the rotational force of the solution during stirring also assists the rotating ring 221 in rotating. As the rotating ring 221 rotates, it disturbs the solution between the inner cylinder 113 and the outer cylinder 211 through multiple inclined plates 223. At the same time, when the rotating ring 221 rotates, it will... The rotation of 224 accelerates the downward flow of the solution between the composite electrode 111 and the inner cylinder 113. At the same time, by disturbing the solution between the inner cylinder 113 and the outer cylinder 211, the problem of the solution between the inner cylinder 113 and the outer cylinder 211 not easily entering the surface of the inner cylinder 113 and the solution stagnation in this area can be reduced. This ensures that the solution can be fully exchanged on the surface of the composite electrode 111, while ensuring the uniformity of the fluoride ion concentration distribution on the surface of the composite electrode 111, thereby improving the stability and efficiency of the detection by the composite electrode 111.

[0036] Because hollow ring 301 and hollow ring 322 float on the liquid surface due to the buoyancy of the solution, when the rotating ring 221 disturbs the solution between the inner cylinder 113 and the outer cylinder 211 through multiple inclined plates 223, the disturbed solution causes hollow ring 301 and hollow ring 322 to sway up and down. When hollow ring 322 floats upward, it drives multiple long rods 323 to rise synchronously. At this time, the several conical cylinders on the surface of the multiple long rods 323 are in the solution, and the floating amplitude of hollow ring 322 is limited by the water resistance. At this time, hollow ring 322 and hollow ring 301 will separate and intertwine with the floating of the solution. At this time, hollow ring 322 will drive the guide ring 321 to be in the hollow ring 301. Below 301 and in the region below the liquid surface, when the subsequent solution flows in through the second circular hole on the outer cylinder 211, the flow of the solution will cause the solution surface to flow in the direction of the inclined surface of the guide ring 321. The solution surface flows back along the inclined surface of the guide ring 321 to the outside of the outer cylinder 211. By turning the solution surface back to the outside of the outer cylinder 211, the situation where bubbles rise and remain on the liquid surface after the solution between the inner cylinder 113 and the outer cylinder 211 is disturbed and interacts with the solution entering through the second circular hole can be reduced. By reducing the retention of bubbles on the solution surface, the accuracy of the composite electrode 111 in detecting fluoride ions in the solution can be ensured. At the same time, the continuity of detection by the composite electrode 111 and the smoothness of the solution flow to the surface of the composite electrode 111 are improved.

[0037] When the solution between the inner cylinder 113 and the outer cylinder 211 is stirred, causing the hollow ring 322 and the hollow ring 301 to float downwards, the hollow ring 322 will gradually overlap with the hollow ring 301 as it floats downwards due to the flow resistance of the conical cylinder in the solution. This forms a closed annular plate between the outer cylinder 211 and the inner cylinder 113. At this time, the closed annular plate floats again at the surface of the solution, thereby limiting the floating amplitude of the solution between the inner cylinder 113 and the outer cylinder 211. This reduces the interference of the fluctuation of the solution in this area with the surface solution of the composite electrode 111, further enhancing the stability of the composite electrode 111 during the detection process and improving the detection efficiency of the composite electrode 111.
