Description

Technical Field

[0001] This utility model relates to the field of activated carbon technology, and in particular to an activated carbon adsorption performance testing rack. Background Technology

[0002] Activated carbon is a specially treated porous carbon material made from carbon-containing raw materials through high-temperature carbonization and activation. It can efficiently adsorb organic pollutants and heavy metal ions in water, purify air and remove odors, and can also be used for the purification and refining of food and medicine. It is a key functional material for achieving the separation, purification and refining of substances.

[0003] The activated carbon adsorption performance test rack is an experimental device specifically designed to test the adsorption capacity of activated carbon. By simulating the actual adsorption environment, it quantifies the adsorption efficiency and adsorption capacity of activated carbon under different conditions. This test rack can control the parameters that affect the adsorption process, such as the flow rate, temperature, and pressure of gas or liquid. It provides researchers and manufacturers with accurate and reliable test data, thereby guiding the research and development improvement and quality control of activated carbon, and ensuring that it achieves the expected adsorption effect in practical applications.

[0004] Existing activated carbon adsorption performance testing racks suffer from insufficient accuracy and stability of test results. While these racks simulate standard adsorption conditions by setting up a constant temperature and pressure environment and precisely controlling fluid flow rate, thus avoiding the influence of external environmental interference and obtaining relatively reliable basic data, the existing racks suffer from several drawbacks. When fluid enters the adsorption chamber, activated carbon accumulates at the bottom of the testing space, leading to differences in the concentration and flow rate of the fluid in contact with different parts of the activated carbon. This results in the adsorption process on the activated carbon surface not proceeding synchronously, with some areas experiencing over-adsorption while others experience insufficient adsorption, severely impacting the accuracy and repeatability of the test results. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model provides an activated carbon adsorption performance test rack, including a base 1. The top left and right sides of the base 1 are provided with test grooves 4 to accommodate test mechanisms 2 and hold test liquid. The test mechanisms 2 are set inside the two test grooves 4 to place activated carbon and conduct adsorption performance tests. A bracket 5 is fixedly connected to the top rear side of the base 1 to install and fix the liquid infusion mechanism 3. The liquid infusion mechanism 3 is set on the front side of the bracket 5 to adjust the liquid depth, provide a suitable liquid environment for the test, and control the liquid height in the test grooves 4.

[0033] The testing mechanism 2 includes two rotating shafts 201, which drive the testing disk 207 to rotate, so that the activated carbon can fully contact the liquid. The bottom of each of the two rotating shafts 201 is rotatably connected to the bottom of the corresponding detection tank 4, so as to realize the flexible rotation of the rotating shafts 201. The top of each of the two rotating shafts 201 is fixedly connected to a disk 202, which connects to a rotating rod 206. The top of each of the two disks 202 is provided with a slot 203, into which a plug 205 is inserted to realize the installation of the rotating rod 206. The inside of each of the two slots 203 is connected to a limiting groove 204 to limit the position of the plug 205 and ensure the stability of the installation of the rotating rod 206. The plug 205 is slidably connected inside the two slots 203, connecting the rotating rod 206 and the disk 202. The top of each of the two plugs 205 is fixedly connected to the rotating rod 206 to install the testing disk 207.

[0034] Multiple test plates 207 are fixedly connected to the outer walls of the two rotating rods 206, where activated carbon is placed for adsorption performance testing. Multiple perforations 208 are opened at the bottom of the multiple test plates 207 to ensure that the liquid and activated carbon are in full contact. A sealing component 209 is provided on the top of the base 1 to seal the detection groove 4 and prevent liquid evaporation and impurities from entering.

[0035] A rotating assembly 210 is provided at the bottom of the base 1 to drive the rotating shaft 201 to rotate. The sealing assembly 209 includes two sealing covers 2091 covering the detection groove 4. The bottoms of the two sealing covers 2091 are slidably connected to the top left and right sides of the base 1, which facilitates the opening and closing of the sealing covers 2091. Sealing grooves 2092 are provided on the top left and right sides of the base 1, which work with sealing rings 2093 to achieve sealing. Sealing rings 2093 are fixedly connected to the bottoms of the two sealing covers 2091 to enhance the sealing effect.

[0036] The rotating assembly 210 includes an L-shaped frame 2101 and a motor 2102. The top of the L-shaped frame 2101 is fixedly connected to the bottom left side of the base 1 to achieve the positioning and installation of the L-shaped frame 2101. The bottom of the L-shaped frame 2101 is fixedly connected to the motor 2102 to provide power for the rotation of the rotating shaft 201. The output end of the motor 2102 passes through the L-shaped frame 2101 and is fixedly connected to the bottom of the left rotating shaft 201 to transmit the power of the motor 2102 to the rotating shaft 201. Rollers 2103 are fixedly connected to the bottom of both rotating shafts 201. The synchronous rotation of the two rotating shafts 201 is achieved through a transmission belt 2104. The outer walls of the two rollers 2103 are connected through the transmission belt 2104 to achieve the transmission of power and the synchronous operation of the rotating shafts 201.

[0037] Specifically, the base 1 provides stable support for the entire device. The detection slots 4 on its top left and right sides accommodate the test liquid and the test mechanism 2. A bracket 5 is fixed to the rear top of the base 1, housing the infusion mechanism 3. The two rotating shafts 201 of the test mechanism 2 are rotatably connected to the bottom of the detection slots 4, and are connected to the rotating rod 206 via a top disc 202, slot 203, limiting slot 204, and insert block 205. Activated carbon is placed on the test disc 207 on the rotating rod 206, and a bottom perforation 208 ensures full contact between the liquid and the activated carbon. A sealing assembly 209 is also included. The sealing ring 2093 at the bottom of the sealing cover 2091 cooperates with the sealing groove 2092 on the base 1 to seal the test groove 4, preventing liquid evaporation and impurities from entering. The L-shaped frame 2101 of the rotating assembly 210 fixes the motor 2102. The motor 2102 drives the left rotating shaft 201, which drives the right rotating shaft 201 to rotate synchronously through the roller 2103 at the bottom of the rotating shaft 201 and the transmission belt 2104, so that the test plate 207 rotates, ensuring that the activated carbon is in full contact with the liquid and realizing the effective testing of the activated carbon adsorption performance.

[0038] Reference Figure 2 and Figure 3The infusion mechanism 3 includes a storage tank 301 for storing the liquid required for testing. The rear side of the storage tank 301 is fixedly connected to the front side of the bracket 5, which serves to position and fix the storage tank 301. A groove 302 is provided on the top of the storage tank 301 for installing a water pump 303. The water pump 303 is fixedly connected to the bottom of the inner side of the groove 302 to provide power for liquid delivery. Control valves 304 are provided on the top left and right sides of the two bases 1 to control the flow rate and velocity of the liquid, thereby adjusting the liquid depth in the detection tank 4.

[0039] The water pump 303 is connected to the left and right sides of the infusion pipe 305 to transport the liquid in the storage tank 301 to the detection tank 4. The other ends of the two infusion pipes 305 are respectively connected to the top of the corresponding control valve 304 to realize the controllable transport of liquid from the infusion pipe 305 to the detection tank 4. The outer wall of the two infusion pipes 305 is provided with a fixing component 306 to fix the infusion pipe 305 and prevent it from shaking and shifting. The fixing component 306 includes a fixing frame 3061 to support the infusion pipe 305. Multiple fixing frames 3061 are fixedly connected to the top left and right sides of the storage tank 301 to provide multiple support points to enhance stability. The top of the multiple fixing frames 3061 is rotatably connected with a locking block 3062 to lock the infusion pipe 305 and ensure that the infusion pipe 305 is stably fixed.

[0040] Specifically, in the liquid delivery mechanism 3 of the activated carbon adsorption performance testing rack, the liquid storage tank 301 is fixed to the front of the support 5 at the rear, providing a stable liquid storage location for the test. A water pump 303 is installed in the groove 302 at the top of the tank. The water pump 303, as the core power component, delivers the liquid from the storage tank 301 through the delivery pipes 305 connecting the left and right sides, ensuring that the liquid can flow to the test tank 4. The control valves 304 on the left and right sides of the top of the base 1 can precisely regulate the flow rate and velocity of the liquid in the delivery pipes 305. The liquid depth in the detection tank 4 can be adjusted to meet the liquid environment requirements of different tests. The fixing component 306 on the outer wall of the infusion tube 305 consists of a fixing bracket 3061 and a locking block 3062. Multiple fixing brackets 3061 on the top left and right sides of the liquid storage tank 301 provide support points for the infusion tube 305. The locking block 3062 connected to the top can firmly lock the infusion tube 305, effectively avoiding the problem of unstable liquid delivery or leakage caused by shaking or displacement of the infusion tube 305 during liquid delivery.

[0041] Reference Figure 4 and Figure 5Both insert blocks 205 are slidably connected to the interior of the corresponding limiting grooves 204, facilitating the installation and disassembly of the rotating rod 206 and the disc 202, while limiting the movement range of the insert blocks 205 to ensure the stability of the rotating rod 206 after installation. The two discs 202 are respectively fitted into the interior of the corresponding detection grooves 4, providing positioning and limiting functions for the discs 202, keeping them in the center position of the detection grooves 4 during rotation, ensuring smooth rotation of the test disc 207. The two sealing rings 2093 are slidably connected to the interior of the corresponding sealing grooves 2092, through... A sliding fit achieves a tight connection between the sealing cap 2091 and the base 1. The size of the sealing ring 2093 matches that of the sealing groove 2092, further enhancing the sealing effect and preventing liquid leakage and external impurities from entering the detection groove 4. The two infusion tubes 305 pass through the interior of the corresponding fixing frame 3061 in sequence, providing support points for the infusion tubes 305. The outer wall of the infusion tube 305 fits against the interior of the fixing frame 3061, and the locking block 3062 securely fixes the infusion tube 305, preventing the infusion tube 305 from shaking or shifting during liquid delivery.

[0042] Specifically, the insert 205 is slidably connected to the limiting groove 204, which facilitates the installation of the rotating rod 206 onto the disc 202. The limiting groove 204 can restrict the movement range of the insert 205, preventing the rotating rod 206 from disengaging from the disc 202 during rotation, thus ensuring the stability of the test mechanism 2 structure. The sealing ring 2093 is slidably connected to the sealing groove 2092 and the dimensions are matched, which can form a good sealing effect and further enhance the sealing performance of the sealing assembly 209. The infusion tube 305 passes through the fixing frame 3061 and the two are internally fitted. With the fixing action of the locking block 3062, the infusion tube 305 is firmly fixed to the top of the storage tank 301, preventing the infusion tube 305 from loosening and bending under long-term use or liquid pressure.

[0043] Working principle: Before testing, the activated carbon to be tested is placed on the test tray 207. Since the bottom of the test tray 207 has multiple perforations 208, it ensures full contact between the liquid and the activated carbon. Then, the insert 205 is inserted into the slot 203 and slid into the limiting groove 204, completing the installation and fixation of the rotating rod 206 and the test tray 207. At the start of the test, the rotating assembly 210 plays a crucial role. The L-shaped frame 2101 is fixed to the bottom left side of the base 1, and the motor 2102 mounted on it is powered on and started. The output of the motor 2102 drives the left rotating shaft 201 to rotate. The bottom roller 2103 drives the right roller 2103 and the right rotating shaft 201 to rotate synchronously via the transmission belt 2104, thereby causing the disc 202, rotating rod 206 and test disc 207 at the top of the two rotating shafts 201 to rotate together, allowing the activated carbon to fully contact in the liquid and simulate the actual adsorption environment. During the test, the sealing component 209 plays an important role. The sealing ring 2093 at the bottom of the two sealing covers 2091 cooperates with the sealing groove 2092 at the top of the base 1 to seal the test groove 4, preventing liquid evaporation or external impurities from entering, ensuring the stability of the test environment and the accuracy of the test results.

[0044] After the test is started, the water pump 303 is powered on and operates, transporting the liquid in the storage tank 301 through the infusion pipes 305 connected to its left and right sides. The other end of the infusion pipe 305 is connected to the control valves 304 on the top left and right sides of the base 1. The control valves 304 can control the flow rate and velocity of the liquid according to the test requirements, thereby adjusting the liquid depth in the test tank 4 and ensuring that the activated carbon on the test plate 207 is in the optimal liquid test environment. During the liquid transport process, the fixing component 306 plays an important role. Multiple fixing brackets 3061 on the top left and right sides of the storage tank 301 provide support for the infusion pipe 305. The locking block 3062 connected to the top of the fixing bracket 3061 can lock the infusion pipe 305 to prevent it from shaking or shifting during the liquid transport process, ensuring the stability and accuracy of the liquid transport, and preventing abnormal liquid transport caused by the position change of the infusion pipe 305, which would affect the test results.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
