Description

Technical Field

[0001] This utility model relates to the field of ceramic center tube fixing technology, and in particular to an easily installable and disassembleable ceramic center tube fixing assembly for ICP. Background Technology

[0002] Inductively coupled plasma (ICP) analyzers are advanced analytical instruments used to analyze the elemental composition and content of substances. They utilize high-frequency electromagnetic fields to generate induced currents in inert gases such as argon, causing the gas to ionize and form high-temperature, high-energy plasma. The plasma temperature can reach thousands of degrees Celsius or even higher, exhibiting excellent conductivity and chemical activity. Samples are introduced into the plasma in the form of aerosols, etc. Under the high-temperature plasma environment, the atoms in the sample are excited and ionized, producing a large number of ions and excited-state atoms. When the excited atoms and ions transition from the excited state back to the ground state, they emit characteristic spectra. The spectra emitted by atoms and ions of different elements have specific wavelengths and intensities. By detecting and analyzing these characteristic spectra using a spectrometer, the types and contents of elements present in the sample can be determined.

[0003] The ceramic central tube is a key component of the instrument, serving as the transport channel for sample aerosols and ensuring that samples can accurately and stably enter the plasma region. The inner diameter and shape design of the ceramic central tube affect the sample transport efficiency and uniformity, thus impacting the accuracy of the analytical results. During installation, a fixing component is required. However, the existing fixing component's contact method with the ceramic central tube is unreasonable, causing excessive local pressure on the ceramic central tube, resulting in stress concentration and potential breakage. Current solutions involve using an arc-shaped or multi-faceted contact design at the contact point between the fixing component and the ceramic central tube to distribute pressure evenly across the ceramic central tube surface, reducing stress-induced damage. However, the installation and disassembly process of the ceramic central tube remains cumbersome, requiring multiple tools and consuming significant time and manpower, thus affecting the instrument's maintenance efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an easily installable and disassembled ceramic center tube fixing assembly for ICP, comprising two outer shells. A mounting plate is fixedly connected to the bottom of the bottom outer shell. Two locking slots are provided on the left and right sides of the bottom outer shell.

The bottom of the locking plates engages with the locking slots. Two fixing posts are fixedly connected to the rear side of the inner top wall of the top outer shell. A top frame is fixedly connected to the middle of each fixing post. The bottom end of each fixing post engages with the fixing slot. A cooling mechanism is provided on the top wall of the top outer shell to improve the heat dissipation efficiency inside the assembly.

[0009] The cooling mechanism also includes a handle, the front side of which is fixedly connected to the rear side of the adsorption sponge plate, and a rubber sleeve is fixedly connected to the middle of the handle.

Subsequently, the airflow dissipates heat from the inside of the component through the operation of the cooling fan. The airflow after heat exchange is discharged through multiple heat dissipation slots, thereby reducing the accumulation of heat inside the component. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an easily installable and detachable ceramic center tube fixing assembly for ICP, comprising two outer shells 3. A mounting plate 1 is fixedly connected to the bottom of the bottom outer shell 3. Two locking slots 4 are provided on both the left and right sides of the bottom outer shell 3. A base frame 5 is fixedly connected to the front and rear sides of the inner bottom wall of the bottom outer shell 3, allowing for the initial placement of the ceramic center tube via the base frame 5. Fixing seats 6 are fixedly connected to both the left and right sides of the base frame 5, with fixing slots 7 on the top of the fixing seats 6. Two locking plates 8 are rotatably connected to both the left and right sides of the top outer shell 3. Subsequently, when the top outer shell 3 moves downwards, the top frame 10 can... The ceramic center tube is initially fixed with the base frame 5. The bottom of the locking plate 8 engages with the locking groove 4. Two fixing posts 9 are fixedly connected to the rear side of the inner top wall of the top shell 3. The top frame 10 is fixedly connected to the middle of the fixing post 9. Then, with the flipping of the locking plate 8, it can engage and lock with the locking groove 4, so that the two shells 3 are installed and fixed. The bottom end of the fixing post 9 engages with the fixing groove 7. With the engagement of the fixing post 9 and the fixing groove 7, the top frame 10 and the base frame 5 are locked and engaged. The top wall of the top shell 3 is provided with a cooling mechanism 2, which is used to improve the heat dissipation efficiency inside the component.

[0032] Specifically, by placing the ceramic center tube inside the base frame 5, and then moving the top outer shell 3 downwards, multiple fixing posts 9 and the top frame 10 move downwards synchronously, thereby engaging the two top frames 10 with the base frame 5. The bottom ends of the fixing posts 9 engage with the corresponding fixing grooves 7, thus securing the ceramic center tube. Then, the locking plate 8 is flipped downwards, so that its bottom engages with the corresponding locking groove 4, thereby locking the top outer shell 3 and the bottom outer shell 3. Conversely, by flipping the locking plate 8 upwards, it disengages from the locking groove 4, and then moving the top outer shell 3 upwards, the fixing posts 9 and the top frame 10 move upwards synchronously, thereby disengaging the two top frames 10 from the base frame 5. The bottom ends of the fixing posts 9 disengage from the corresponding fixing grooves 7, thus unlocking and disassembling the top outer shell 3 and the bottom outer shell 3. This avoids the need to use multiple tools for installation and disassembly, thereby improving the maintenance efficiency of the instrument.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The cooling mechanism 2 includes a cooling fan 201. The bottom of the cooling fan 201 is fixedly connected to the top of the top housing 3. An annular pipe 202 is fixedly connected to the top wall of the cooling fan 201, so that when the cooling fan 201 is started, it draws in outside air through the annular pipe 202. The top of the annular pipe 202 is connected to a processing shell 203. Multiple filter columns 204 are equidistantly connected to the top wall of the processing shell 203, so that the outside air can be filtered through the multiple filter columns 204. An adsorption sponge plate 205 is slidably connected to the inner wall of the processing shell 203, and then the adsorption sponge plate 205 is used to adsorb and dry the water vapor, avoiding damage to the inside of the component by the heat dissipation airflow. Heat dissipation grooves 208 are opened at the bottom of both the housing 3 and the mounting plate 1.

[0034] Specifically, by activating the cooling fan 201, external air is drawn through multiple filter columns 204. The air then passes through the filter columns 204 to filter out larger particles, preventing damage to the ceramic central tube and ensuring stable operation and extended service life. Subsequently, the airflow passes through the adsorption sponge plate 205 to adsorb moisture in the airflow, effectively preventing damage to the internal components caused by moisture in the airflow during the cooling process and ensuring the safety of the internal components. The airflow then dissipates heat from the internal components through the operation of the cooling fan 201, allowing the heat-exchanged airflow to be discharged through multiple heat dissipation slots 208, effectively reducing the accumulation of heat inside the components and thus improving the heat dissipation efficiency and performance stability of the equipment.

[0035] Reference Figure 1 , Figure 4 and Figure 5The cooling mechanism 2 also includes a handle 206, the front side of which is fixedly connected to the rear side of the adsorption sponge plate 205, and a rubber sleeve 207 is fixedly connected to the middle of the handle 206; a control switch 17 is fixedly connected to the front side of the top housing 3, and the control switch 17 is electrically connected to the cooling fan 201; rubber pads 15 are fixedly connected to the bottom of the two top frames 10 and the inner wall of the two base frames 5, and the outer wall of the rubber pads 15 is designed to be smooth.

[0036] Specifically, the connection between the handle 206 and the rubber sleeve 207 improves the anti-slip effect when using the handle 206. The control switch 17, which is electrically connected to the cooling fan 201, enables the cooling fan 201 to be turned on and off. The rubber pad 15 reduces the pressure damage to the ceramic center tube caused by the top frame 10 and the bottom frame 5.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Sealing plates 11 are fixedly connected to the left and right sides of the bottom wall of the top shell 3, and sealing grooves 12 are fixedly connected to the left and right sides of the top wall of the bottom shell 3. The bottom of the sealing plate 11 is engaged with the sealing groove 12. Multiple mounting grooves 16 are opened on the top of the mounting plate 1, and the multiple mounting grooves 16 are opened at equal intervals. Limiting posts 13 are fixedly connected to the four corners of the bottom wall of the top shell 3, and limiting grooves 14 are opened at the four corners of the top wall of the bottom shell 3. The bottom end of the limiting post 13 is engaged with the limiting groove 14.

[0038] Specifically, the engagement of the sealing plate 11 and the sealing groove 12 improves the sealing effect between the two outer shells 3, the multiple mounting grooves 16 facilitate the fixed installation of the components, and the engagement of the limiting post 13 and the limiting groove 14 improves the strength when the two outer shells 3 are connected.

[0039] Working principle: When starting to use, the ceramic center tube is placed inside the base frame 5, and then the top outer shell 3 is moved downward, so that multiple fixing columns 9 and the top frame 10 move downward synchronously. Then, the two top frames 10 and the base frame 5 are engaged, and the bottom end of the fixing column 9 is engaged with the corresponding fixing groove 7 to fix it, thereby achieving the purpose of fixing the ceramic center tube. Then, the locking plate 8 is flipped down so that its bottom is engaged with the corresponding locking groove 4, thereby locking the top outer shell 3 and the bottom outer shell 3. Conversely, disassembly is completed, thus avoiding the need to use multiple tools for installation and disassembly, thereby improving the maintenance efficiency of the instrument.

[0040] Furthermore, by activating the cooling fan 201, it draws in outside air through multiple filter columns 204. The air then passes through the filter columns 204 to filter out larger particles, preventing damage to the ceramic central tube from larger particles. Subsequently, the airflow passes through the adsorption sponge plate 205 to adsorb moisture in the airflow, preventing the possibility of moisture in the airflow causing damage to the inside of the module during the cooling process. Then, the airflow dissipates heat from the inside of the module through the operation of the cooling fan 201, so that the airflow after heat exchange is discharged through multiple heat dissipation slots 208, reducing the accumulation of heat inside the module.

[0041] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
