Description

Technical Field

[0001] This utility model belongs to the field of testing instrument technology, specifically a portable activated carbon iodine value testing device. Background Technology

[0002] Activated carbon, as a highly efficient adsorption material, is widely used in air purification and water treatment. It is renowned for its porosity and high specific surface area, effectively removing harmful gases and odors from the air. However, the adsorption capacity of activated carbon is not constant; it gradually weakens over time and under changing usage conditions. Therefore, accurately detecting the iodine value of activated carbon is crucial. The iodine value, as one of the important indicators for measuring the adsorption capacity of activated carbon, reflects its ability to adsorb iodine molecules. By detecting the iodine value of activated carbon, its performance and quality can be assessed. Accurate detection of the iodine value of activated carbon is also an important means of rapidly responding to environmental pollution incidents and protecting public health and environmental safety.

[0003] The existing technology still has the following shortcomings:

[0004] 1. Existing activated carbon iodine value testing devices are bulky and inconvenient to carry. When relevant professionals need to go out to test the iodine value of activated carbon, they can only bring the samples to the laboratory for testing, which is time-consuming and inefficient.

[0005] 2. Existing activated carbon iodine value testing devices are complex to operate. They usually require multiple devices to perform different steps, which requires certain professional knowledge, making them difficult to use and costly. Utility Model Content

[0006] To overcome the above-mentioned shortcomings, this utility model provides a portable activated carbon iodine value detection device, which solves the problems of lack of portability and complicated operation.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable activated carbon iodine value testing device, comprising an iodine solution container, a crushing and stirring container threadedly connected to the lower part of the iodine solution container, a titration container threadedly connected to the lower part of the crushing and stirring container, a handle fixedly connected to the upper part of the iodine solution container, and an iodine solution filling port opened on the upper part of the iodine solution container.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A portable activated carbon iodine value testing device includes an iodine solution container 1, a crushing and stirring container 2 threadedly connected to the lower part of the iodine solution container 1, a titration container 3 threadedly connected to the lower part of the crushing and stirring container 2, a handle 4 fixedly connected to the upper part of the iodine solution container 1, and an iodine solution filling port 5 opened on the upper part of the iodine solution container 1.

[0024] Specifically, the iodine solution container 1, the crushing and stirring container 2, and the titration container 3 are assembled by threads, and iodine solution is added to the inside of the iodine solution container 1 through the iodine solution filling port 5;

[0025] An iodine solution container 1 is fixedly connected to a partition. A liquid outlet pipe is provided between the partition and the bottom of the iodine solution container 1. A baffle 16 is provided above the partition, which is located above the liquid outlet pipe and seals the upper end of the liquid outlet pipe. A rotating shaft 15 is fixedly connected below the baffle 16. The rotating shaft 15 passes through the partition and is rotatably connected to the partition. A gear 14 is fixedly connected below the rotating shaft 15. A rack 11 is provided on one side of the gear 14. A fixed plate 12 is fixedly connected below the partition. The rack 11 passes through the fixed plate 12 and is slidably connected to the fixed plate 12. An iodine solution switch 6 is fixedly connected to the end of the rack 11 away from the gear 14. A spring 13 is provided between the iodine solution switch 6 and the fixed plate 12. The spring 13 is sleeved on the outside of the rack 11. The iodine solution switch 6 passes through the side wall of the iodine solution container 1 and is slidably connected to the iodine solution container 1.

[0026] Specifically, when it is necessary to add iodine solution to the inside of the pulverizing and stirring container 2, press the iodine solution switch 6. The iodine solution switch 6 drives the rack 11 to move, causing the spring 13 to contract. The rack 11 drives the gear 14 that meshes with it to rotate. When the gear 14 rotates, it drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the baffle 16 to rotate around the rotating shaft 15, so that the iodine solution flows into the inside of the pulverizing and stirring container 2 through the outlet pipe. During this process, the rotation angle of the baffle 16 can be controlled according to the force of pressing the iodine solution switch 6, thereby adjusting the flow rate of the outlet pipe.

[0027] A motor 7 is fixedly connected to the bottom of the iodine solution container 1, and a blade 8 is fixedly connected to the output end of the motor 7.

[0028] Specifically, the motor 7 is started, and the output end of the motor 7 drives the blade 8 to rotate, which crushes the activated carbon. After adding iodine solution, the blade 8 stirs the mixture to make it fully blended.

[0029] The internal workings of the titration container 3 are connected to a filter screen 9 and a burette 10. The burette 10 is located below the filter screen 9. The iodine solution container 1 and the titration container 3 are made of transparent material. The iodine solution container 1 and the titration container 3 are provided with graduation lines on their outer sides. The threads on the top and bottom of the crushing and stirring container 2 are adapted to the threads of the iodine solution container 1 and the titration container 3.

[0030] Specifically, remove the burette 10 from inside the titration container 3. Connect the upper end of the pulverizing and stirring container 2 (containing a mixture of activated carbon and iodine solution) to the upper end of the titration container 3 via threads. Invert the pulverizing and stirring container 2 so that the filter screen 9 filters the mixture. The filtered solution falls to the bottom of the titration container 3. Then remove the filter screen 9 along with the filtered mixture. Reinstall the burette 10 back into the titration container 3. Pour sodium thiosulfate above the burette 10 and titrate the filtered solution. Add iodine solution precisely according to the graduations on the iodine solution container 1, and calculate the adsorption value according to the graduations on the titration container 3.

[0031] The working principle of this utility model is as follows:

[0032] First, add iodine solution into the iodine solution container 1 through the iodine solution filling port 5. Alternatively, add sufficient iodine solution in advance for later use. Then, unscrew the iodine solution container 1 and the grinding and stirring container 2, and add activated carbon into the grinding and stirring container 2. Tighten the iodine solution container 1 and the grinding and stirring container 2. Start the motor 7. The output of the motor 7 drives the blades 8 to rotate, grinding the activated carbon. Next, press the iodine solution switch 6. The iodine solution switch 6 moves the rack 11, causing the spring 13 to contract. The rack 11 drives the gear 14, which in turn rotates. When the gear 14 rotates, it drives the rotating shaft 15 to rotate. The rotating shaft 15 drives the baffle 16 to rotate around the shaft 15, allowing the iodine solution to flow into the grinding and stirring container 2 through the outlet pipe. During this process, the rotation angle of the baffle 16 can be controlled by the pressure applied to the iodine solution switch 6, thereby adjusting the flow rate of the outlet pipe. Add iodine solution precisely according to the graduation lines on the iodine solution container 1. Start the motor 7. The output of the motor 7 drives the blades 8 to rotate, stirring the mixture to ensure thorough mixing. Next, remove the burette 10 from inside the titration container 3. Connect the upper end of the pulverizing and stirring container 2, which contains a mixture of activated carbon and iodine solution, to the upper end of the titration container 3 via threads. Invert the pulverizing and stirring container 2 so that the filter screen 9 filters the mixture. The filtered solution falls to the bottom of the titration container 3. Then remove the filter screen 9 along with the filtered mixture. Reinstall the burette 10 back into the titration container 3. Pour sodium thiosulfate above the burette 10 and titrate the filtered solution. Calculate the adsorption value according to the graduations on the titration container 3.

[0033] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
