Description

Technical Field

[0001] This utility model relates to the technical field of activated carbon detection equipment, specifically a butane adsorption analyzer for activated carbon detection. Background Technology

[0002] The butane adsorption analyzer is an important tool for evaluating the performance of activated carbon, especially in measuring its adsorption capacity. This instrument is typically used to test characteristics such as the specific surface area, pore volume, and pore size distribution of activated carbon. By using butane as the adsorbate, activated carbon samples can be analyzed under specific conditions (such as temperature and pressure) to determine their adsorption characteristics. In operation, a certain amount of activated carbon sample is first placed in the analyzer, and butane gas is introduced. Then, under set conditions, the amount of butane gas adsorbed by the activated carbon is monitored. By analyzing these data, the adsorption isotherm of the activated carbon can be calculated, and further information about its structural characteristics can be obtained. The butane adsorption analyzer is widely used in environmental protection, chemical, and pharmaceutical fields, and is of great significance for studying the adsorption performance of activated carbon materials and optimizing their application conditions.

[0003] The patent with publication number CN217359466U discloses an activated carbon butane adsorption analyzer, which includes a base plate, on which are mounted a first chamber and a second chamber. A partition is installed inside the first chamber. An electric heater is installed at the bottom of the first chamber on the left side of the partition, and a sample tube is connected to a serpentine tube. A n-butane gas cylinder is detachably mounted inside the first chamber on the right side of the partition. A drying bottle and an activated carbon purification bottle are installed inside the second chamber. An air inlet is connected to the drying bottle, and the drying bottle is connected to the activated carbon purification bottle. A T-connector is connected to the rear end of the activated carbon purification bottle, and a nitrogen inlet is connected to one end of the T-connector. A T-connector is connected between the T-connector, the sample tube, and the n-butane gas cylinder. This device can accurately determine the working capacity of activated carbon for butane adsorption. The serpentine tube ensures a constant temperature of the gas passing through the activated carbon sample. Openable covers (first and second) facilitate the replacement of internal components, improving experimental efficiency.

[0004] However, the activated carbon butane adsorption analyzer described above still has the following problems: Although heating the water in the chamber by electric heating can achieve uniform and stable heating of the gas in the serpentine tube, there are certain issues in practical applications. During the electric heating process, the water at the bottom of the chamber heats up first, while the water at the top heats up more slowly, resulting in uneven water temperature distribution within the chamber. This temperature difference is transmitted to the serpentine tube, affecting the heat exchange effect and consequently causing poor uniformity and stability of gas heating. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a butane adsorption analyzer for activated carbon detection, which improves the stability of the analyzer in gas heating.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a butane adsorption analyzer for activated carbon detection, comprising an analyzer body and a heating chamber disposed within the analyzer body, wherein a heat exchange tube is disposed within the heating chamber, the heat exchange tube being disc-shaped and located in the middle of the heating chamber, one end of the heat exchange tube being fixedly connected to and communicating with a sample tube, and a stirring assembly and a heating rod being connected within the heating chamber.

[0010] Furthermore, a T-shaped block is fixedly connected to the end of the hoisting rod away from the heating rod, and an installation block is fixedly connected to the top inner wall of the heating chamber. A T-shaped groove is opened on the top of the installation block, and the T-shaped block and the T-shaped groove are slidably connected.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figures 1 to 4 The butane adsorption analyzer for activated carbon detection includes an analyzer body 1 and a heating chamber 101 disposed within the analyzer body 1. A heat exchange tube 2 is disposed within the heating chamber 101. The heat exchange tube 2 is disc-shaped and located in the middle of the heating chamber 101. One end of the heat exchange tube 2 is fixedly connected to and communicates with a sample tube 3. A stirring assembly 4 and a heating rod 5 are also connected within the heating chamber 101.

[0018] like Figures 1 to 4 As shown, the butane adsorption analyzer for activated carbon detection in this invention is structurally similar to existing butane adsorption analyzers for activated carbon detection, such as the butane adsorption analyzer for activated carbon disclosed in patent publication number CN217359466U. The main improvement of this invention lies in improving the heating effect of butane gas in heat exchange tube 2, such as... Figures 1 to 4 As shown, in the butane adsorption analyzer for activated carbon detection of this utility model, the heating rod 5 heats the water in the heating chamber 101, and the stirring component 4 stirs the water in the heating chamber 101 at the same time, so that the water heated by the heating rod 5 can be quickly mixed with the surrounding low temperature water, making the water temperature in the heating chamber 101 more uniform, thereby making the heat exchange tube 2 obtain a more uniform heat exchange effect.

[0019] like Figure 2 As shown, the heating rod 5 is located in the middle of the heat exchange tube 2. Installing the heating rod 5 in the middle of the heat exchange tube 2 allows the heated water to diffuse evenly from the center to the surrounding area, thus making the disc-shaped heat exchange tube 2 more evenly heated.

[0020] like Figure 2 As shown, the heating rod 5 and the heat exchange tube 2 have their axes aligned. This alignment ensures a more uniform heating effect from top to bottom within the heating chamber 101, resulting in a more even temperature rise of the water within the chamber and improving the heating efficiency of the disc-shaped heat exchange tube 2 within the heating chamber 101.

[0021] like Figure 2 and Figure 4 As shown, a lifting rod 6 is connected to the top side wall of the heating chamber 101. The heating rod 5 is fixedly connected to the bottom of one end of the lifting rod 6, and the heating rod 5 is suspended in the middle position of the heat exchange tube 2 by the lifting rod 6. Suspending the heating rod 5 in the middle position of the heat exchange tube 2 by the lifting rod 6 can avoid the heating rod 5 from contacting the stirring assembly 4 and the heat exchange tube 2, thereby improving the performance of the heating rod 5.

[0022] like Figure 2 and Figure 4 As shown, a T-shaped block 7 is fixedly connected to the end of the lifting rod 6 away from the heating rod 5. A mounting block 8 is fixedly connected to the top inner wall of the heating cavity 101. A T-shaped groove 801 is formed on the top of the mounting block 8, and the T-shaped block 7 is slidably connected to the T-shaped groove 801. The connection between the T-shaped block 7 and the T-shaped groove 801 on the mounting block 8 facilitates the removal and replacement of the heating rod 5 from the heating cavity 101 via the lifting rod 6, allowing for timely replacement of the heating rod 5 when it is damaged, thus improving the applicability of the measuring instrument.

[0023] like Figure 3 As shown, the stirring assembly 4 includes a stirring motor 41 and a rotating rod 42. The stirring motor 41 is embedded in the middle of the bottom of the heating chamber 101. The output axis of the stirring motor 41 extends upward through the heating chamber 101 and is fixedly connected to the rotating rod 42. The heat exchange tube 2 is located above the rotating rod 42. The stirring motor 41 embedded in the bottom of the heating chamber 101 drives the rotating rod 42 to rotate at the bottom of the heating chamber 101, thereby stirring the water in the heating chamber 101. This allows the water heated by the heating rod 5 to mix quickly with the unheated water, making the water temperature in the heating chamber 101 more uniform. It should be noted that the bottom of the heat exchange tube 2 is suspended in the heating chamber 101 and does not come into contact with the rotating rod 42, ensuring that the stirring process does not cause collision damage to the heat exchange tube 2.

[0024] like Figure 3 As shown, stirring rods 43 are fixedly connected to both ends of the rotating rod 42 on the side away from the stirring motor 41, and the two stirring rods 43 are located on both sides of the heat exchange tube 2. The vertical stirring rods 43 are fixedly installed at both ends of the rotating rod 42 to further increase the stirring and mixing effect of the water in the heating chamber 101 and improve the uniformity of the internal water temperature. The two stirring rods 43 are located on the outside of the disc-shaped heat exchange tube 2 and do not contact the heat exchange tube 2.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
