Description

Technical Field

[0001] This utility model relates to the technical field of carbon and sulfur analysis equipment, specifically to a carbon and sulfur analyzer sample introduction device. Background Technology

[0002] During the carbon-sulfur analyzer's testing process, a magnetic boat carrying the sample needs to be fed into the combustion tube for high-temperature combustion. Existing devices typically use a push rod to complete the feeding action. However, in the boat replacement stage after sample analysis, a clamping tool is often used to clamp and replace the high-temperature magnetic boat: the operator first uses the clamping tool to remove the used high-temperature magnetic boat, and then clamps the new magnetic boat and places it on the push rod or the corresponding support position.

[0003] While this method avoids direct contact with the high-temperature magnetic boat, it still has significant shortcomings: First, the boat-changing process relies entirely on manual sequential operation, requiring the old boat to be removed before the new boat is placed in each cycle, resulting in cumbersome and inefficient operation steps that are difficult to meet the needs of batch testing; Second, there are still safety hazards when handling the high-temperature magnetic boat, as operators are easily exposed to heat radiation or even burned when using clamping tools near the high-temperature combustion pipe opening.

[0004] Therefore, there is an urgent need for a loading and unloading mechanism that can automatically remove the old boat and automatically position the new boat by means of the linear reciprocating motion of the push rod, thereby reducing manual intervention, improving boat changing efficiency, and reducing the risk of high-temperature operations. Utility Model Content

[0005] This invention provides a carbon-sulfur analyzer sample introduction device to solve the technical problem that the replacement of the magnetic boat in the prior art requires manual operation with the help of clamping tools, resulting in low operating efficiency and safety hazards caused by high-temperature operation.

[0006] According to one aspect of the present invention, a carbon-sulfur analyzer sample introduction device is provided, including a base as a supporting carrier; The push rod slides in a straight line with the base. A guide groove is formed along the length of the push rod. The two side walls of the guide groove are used to cooperate with the magnetic boat to support and guide the magnetic boat. The magnetic boat loading and unloading fixing rod is installed on the base. One end of the magnetic boat loading and unloading fixing rod extends above the guide groove. It is used to block the magnetic boat when the push rod slides, so as to keep the magnetic boat stationary and realize the relative movement between the push rod and the magnetic boat.

[0007] Optionally, one end of the push rod is provided with a splash-proof arched cover that covers the guide groove. The side of the splash-proof arched cover near the magnetic boat loading and unloading fixing rod forms a magnetic boat inlet, and the side of the splash-proof arched cover away from the magnetic boat loading and unloading fixing rod forms a magnetic boat outlet.

[0008] Optionally, the bottom of the splash-proof arched cover is provided with a plug-in block, and the push rod is provided with a plug-in groove that mates with the plug-in block.

[0009] Optionally, a magnetic boat collecting trough and a magnetic boat collecting box are provided on the base. The inlet of the magnetic boat collecting trough is located below the magnetic boat outlet, and the outlet end of the magnetic boat collecting trough is connected to the magnetic boat collecting box.

[0010] Optionally, a pull-out hole is provided at the bottom of the base, and the magnetic boat collection box is slidably installed in the pull-out hole, with the top of the magnetic boat collection box being open.

[0011] Optionally, height-adjustable feet are provided at the four corners of the base.

[0012] Optionally, a bubble level is provided on the top surface of the base, and the bubble level is parallel to the push rod.

[0013] Optionally, a scale is provided on the top surface of the base along the length of the push rod.

[0014] Optionally, the push rod includes a crossbeam and an auxiliary plate, which are arranged vertically to make the cross section of the push rod T-shaped, and the base is provided with a guide rail groove that mates with the crossbeam.

[0015] Optionally, a support frame spanning the push rod is provided on the base, and the magnetic boat loading and unloading fixing rod is installed on the support frame. The support frame and the base are detachably connected.

[0016] In summary, this application includes at least one of the following beneficial technical effects: By employing the structure of this invention, the operator only needs to place multiple magnetic boats sequentially on the guide groove of the push rod once. In subsequent testing cycles, continuous automatic boat changing is achieved through the reciprocating motion of the push rod. When the magnetic boat at the tail end completes testing, the push rod pulls back, and the magnetic boat remains stationary under the obstruction of the magnetic boat loading and unloading fixing rod, thus creating relative sliding with the push rod. This causes the tail-end magnetic boat to automatically detach from the push rod and be retrieved. The penultimate magnetic boat then reaches the tail end to become a new testing boat. This cycle allows for multiple sample injections without manual replacement, ensuring the continuity and high efficiency of the testing process, simplifying the operation, and avoiding the safety risks associated with frequent contact between the operator and the high-temperature magnetic boat near the combustion port. Furthermore, the boat changing and push rod movement are synchronized, significantly improving the overall efficiency and safety of the carbon-sulfur analyzer.

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] This application discloses a carbon-sulfur analyzer sample introduction device.

[0023] Reference Figure 1 The carbon-sulfur analyzer sample introduction device includes a base 4, a push rod 7, and a magnetic boat loading and unloading fixing rod 8. The base 4 serves as the supporting carrier for the entire device, used to install and fix other components, ensuring that the push rod 7 can move smoothly in a predetermined direction during operation. The base 4 not only bears the load but also limits the movement trajectory of the push rod 7, making the overall structure of the device stable and reliable.

[0024] The push rod 7 slides along the base 4 in a straight line, and a guide groove 10 is formed along its length. The guide groove 10 is a limiting channel for accommodating the magnetic boat, and its side walls match the shape of the magnetic boat, providing effective support and constraint. Through this engagement, the magnetic boat can remain stable during the linear movement of the push rod 7, without lateral displacement or tilting, thus ensuring the accurate posture of the magnetic boat when it is sent into the combustion tube, and avoiding sample tipping or detection errors caused by displacement.

[0025] The magnetic boat loading and unloading fixing rod 8 is mounted on the base 4, with one end extending downwards above the guide groove 10. During the linear movement of the push rod 7, the fixing rod can block the magnetic boat, keeping it stationary. When the push rod 7 is pushed forward, it carries the entire magnetic boat into the combustion tube for analysis; when the push rod 7 is pulled backward, the fixing rod prevents the magnetic boat from retracting with the push rod 7, thus creating relative motion between the push rod 7 and the magnetic boat. Through this relative motion, pushing the push rod 7 allows the magnetic boat located at the tail end of the push rod 7 to be removed or replaced, while the new magnetic boat moves to the position to be tested, realizing an automatic loading and unloading process. This avoids the tediousness and high-temperature operation risks of manually replacing magnetic boats one by one using clamping tools, significantly improving operational efficiency, ensuring sample introduction stability, and reducing safety hazards.

[0026] Reference Figure 2 In one embodiment, the guide groove 10 on the push rod 7 has a trapezoidal cross-section, wider at the top and narrower at the bottom. This design allows the magnetic boat to be automatically positioned downwards when placed within the guide groove 10, while the side walls exert an inward restraining force on the boat, preventing it from swaying or tilting due to excessive gaps during longitudinal transport. Simultaneously, the wider upper opening facilitates quick loading and smooth introduction of the magnetic boat into the guide groove 10, improving operational convenience. Thus, the trapezoidal cross-section ensures stable support of the magnetic boat during operation while also balancing ease of loading, thereby further enhancing the reliability and efficiency of the sample introduction device.

[0027] In one embodiment, the push rod 7 includes a crossbeam 71 and an auxiliary plate 72, which are arranged perpendicularly to each other, making the overall cross-section of the push rod 7 T-shaped. The crossbeam 71 extends horizontally, with its two ends embedded in guide grooves on the top surface of the base 4. The guide grooves limit and guide the crossbeam 71, ensuring that the push rod 7 can slide smoothly in a straight line without deflection or detachment. The auxiliary plate 72 is vertically positioned in the middle of the crossbeam 71 to transmit the thrust applied by the operator. The combination of the auxiliary plate 72 and the crossbeam 71 not only forms a typical T-shaped cross-section but also gives the push rod 7 higher rigidity and strength during longitudinal movement.

[0028] In practical use, the operator drives the push rod 7 to reciprocate via the push handle. The crossbeam 71 slides linearly under the constraint of the guide rail groove, ensuring that the magnetic boat can be stably fed into or out of the combustion tube. Since the auxiliary plate 72 is arranged vertically, the thrust acts directly on the guide groove 10 where the magnetic boat is located, avoiding bending caused by eccentric force. Compared with traditional cylindrical or strip-shaped push rods 7, the T-shaped cross-section significantly enhances bending strength and torsional stiffness, making it more suitable for linear movement within the narrow combustion tube and effectively avoiding the risk of breakage due to insufficient force on the push rod 7. Furthermore, during sample injection, the bottom auxiliary plate 72 can contact the inner wall of the combustion tube, further distributing and transferring the load, thus preventing deformation or breakage of the push rod 7 under high-temperature, high-frequency reciprocating working conditions, significantly improving the durability and reliability of the push rod 7. Through this structural design, the push rod 7 can both bear the weight of the magnetic boat tray and the sample and maintain the stability of the sample injection path, thereby ensuring the accurate position of the sample in the combustion zone and the detection effect.

[0029] It can be seen that the structure of the T-shaped push rod 7 and the guide rail groove of the base 4 not only achieves smooth guidance of the push rod 7's movement, but also greatly improves the working reliability and service life of the sample injection device by enhancing the cross-sectional strength and rationalizing the force, while reducing maintenance costs.

[0030] Reference Figure 3 In one embodiment, one end of the push rod 7 is provided with a splash-proof arched cover 9 that covers the guide groove 10. This splash-proof arched cover 9 is arched in shape, with open structures at both ends. It not only covers the guide groove 10 to form a protective space but also maintains unobstructed gas flow in the sample inlet channel, preventing interference with atmosphere exchange during combustion. A magnetic boat inlet is located on the side of the arched cover near the magnetic boat loading / unloading fixing rod 8, allowing the magnetic boat to be smoothly placed into the guide groove 10 before sample injection. A magnetic boat outlet is located on the side of the arched cover away from the magnetic boat loading / unloading fixing rod 8, allowing the magnetic boat to slide out smoothly or be ejected when the analysis is completed or the push rod 7 returns. This corresponding arrangement of the inlet and outlet allows the magnetic boat to flow unidirectionally along the guide groove 10, ensuring a clear path for boat changing and preventing unnecessary backtracking or jamming of the magnetic boat within the guide groove 10. The anti-splash arched cover 9 covers the guide groove 10 where the magnetic boat is located during operation. The structure of the arched cover can effectively block the molten material and splash particles generated by the sample during high-temperature combustion, preventing them from directly adhering to the inner wall of the combustion tube or falling into the surrounding area of ​​the guide groove 10, thereby reducing the risk of damage to the combustion tube due to uneven local thermal stress.

[0031] To facilitate the fixing and disassembly of the anti-splash arched cover 9 and the push rod 7, a plug-in block 12 is provided at the bottom of the anti-splash arched cover 9, and a corresponding plug-in groove is provided on the push rod 7 to mate with the plug-in block 12. After the plug-in block 12 is inserted into the plug-in groove, the arched cover can be securely locked, keeping it stable during the reciprocating movement of the push rod 7 without loosening or shifting. When it is necessary to clean molten residue or replace protective parts, the arched cover can be quickly disassembled simply by pulling out the plug-in block 12, thereby greatly improving the convenience of maintenance.

[0032] In one embodiment, a push handle is provided at the end of the push rod 7 furthest from the anti-splash arch shroud 9. The push handle is fixed to the push rod 7 and extends outside the base 4. The operator can push or pull the push rod 7 forward by holding the push handle, thereby enabling the magnetic boat to be fed in and out. Since the push handle and push rod 7 are an integrated transmission structure, the stability of the push rod 7 during linear movement can be ensured, avoiding uneven force caused by directly pushing the push rod 7 body. At the same time, the push handle improves the comfort and safety of operation, allowing the operator to complete the sample injection action at a distance from the combustion tube, reducing the operational risks in high-temperature environments.

[0033] In one embodiment, a magnetic boat collecting trough 3 and a magnetic boat collecting box 1 are provided on the base 4. The inlet of the magnetic boat collecting trough 3 corresponds to the outlet below the anti-splash arch shroud 9. When the magnetic boat is pushed out by the new magnetic boat and slides out of the guide trough 10 after the analysis is completed, the waste magnetic boat can smoothly enter the guide trough. In order to ensure that the waste magnetic boat can slide smoothly, the guide trough is designed as a ramp structure with an optimized inclination angle, which allows the magnetic boat to slide naturally along the ramp by its own weight without getting stuck or stopping. The outlet end of the guide trough is connected to the magnetic boat collecting box 1, so that the waste magnetic boat is finally received by the collecting box.

[0034] A pull-out hole is provided at the bottom of the base 4, and the magnetic boat collection box 1 is slidably installed within this hole. The top of the collection box is open, allowing the magnetic boats to fall directly into the collection box from the guide channel. This design allows the operator to easily remove the used magnetic boats at once by simply pulling the collection box out from the bottom of the base 4 when cleaning is needed, making the cleaning process quick and avoiding the inconvenience and risk of manually handling each hot magnetic boat individually. To further enhance the operator's convenience, a handle is also provided on the outside of the collection box, allowing the operator to smoothly pull the collection box out or push it into the base 4. This not only makes cleaning and replacement operations more effortless but also avoids the potential high-temperature risk from direct contact with the box.

[0035] With the above structure, the waste magnetic boat can automatically detach and enter the collection box during the return stroke of push rod 7, achieving synchronous connection with the placement of the new magnetic boat. This avoids the safety hazards of frequent manual handling of high-temperature magnetic boats and improves the automation level and overall work efficiency of the sample introduction process. At the same time, the sloping design of the guide channel ensures a clear sliding path and smooth movement of the waste magnetic boat, further reducing the risk of downtime due to jamming.

[0036] In one embodiment, height adjustment feet 2 are provided at the four corners of the base 4. By turning the adjustment feet, the height and level of the base 4 can be precisely adjusted to compensate for the effects of uneven mounting surface, ensuring that the push rod 7 and the sample inlet of the combustion tube are on the same horizontal line, thereby ensuring that the magnetic boat can be smoothly delivered into the analysis area. A bubble level 5 is provided on the top surface of the base 4, and the bubble level 5 is arranged parallel to the push rod 7. The bubble level 5 can visually display the level status of the base 4, and the operator can quickly adjust the adjustment feet according to its indication to achieve precise horizontal positioning of the base 4, ensuring that the push rod 7 moves straight and stably.

[0037] Specifically, each adjusting foot includes an outer sleeve and a threaded rod. The threaded rod is threaded into the outer sleeve, and a support pad is located at the lower end of the threaded rod, contacting the mounting platform. By rotating the threaded rod, the support pad can be moved up and down vertically, thereby changing the height of the base 4. When multiple adjusting feet are adjusted in conjunction, the overall level of the base 4 can be precisely corrected. In actual use, the operator can first determine whether the base 4 is level according to the indication of the bubble level 5, and then compensate for unevenness of the platform or installation deviation by turning the adjusting feet one by one. Due to the presence of threaded transmission, the adjustment action has high precision and stability, ensuring that the push rod 7 and the combustion tube inlet are on the same horizontal line, preventing the magnetic boat from shifting or getting stuck in the guide groove 10 due to tilting. Thus, the adjusting feet not only provide a height matching function during device installation, but also realize micro-leveling of the base 4, making the sample injection process more stable and reliable, and ensuring the repeatability and accuracy of the test results.

[0038] In one embodiment, a scale 6 is provided on the top surface of the base 4 along the length of the push rod 7, with the zero position of the scale 6 corresponding to the reference position of the push rod 7. The push rod 7 has an indicator section corresponding to the scale 6, which can visually display its displacement position during reciprocating motion. In use, the operator can determine the specific position of the magnetic boat during the pushing process based on the scale 6, ensuring that the magnetic boat is accurately delivered into the analysis zone of the combustion tube. The scale 6 provides visualization and repeatability of the sample injection position, improving the stability and efficiency of the detection process.

[0039] Reference Figure 1In one embodiment, a support frame 11 spanning the push rod 7 is provided on the base 4, and the magnetic boat loading / unloading fixing rod 8 is installed on the support frame 11. The support frame 11 and the base 4 are detachably connected. Specifically, the support frame 11 includes a horizontal bar and two vertical bars, with the two vertical bars located on both sides of the push rod 7. The horizontal bar connects the two vertical bars and spans above the push rod 7, and the magnetic boat loading / unloading fixing rod 8 is fixedly installed on the horizontal bar. The lower ends of the two vertical bars are provided with insertion parts, which can be inserted into the corresponding insertion holes in the base 4, thereby achieving a reliable connection between the support frame 11 and the base 4. When cleaning or replacement is required, the operator can pull the vertical bars out of the base 4, thereby disassembling the entire support frame 11 and the magnetic boat loading / unloading fixing rod 8 together, making the maintenance process simple and quick.

[0040] During use, the push rod 7 reciprocates linearly along the guide groove 10, and the magnetic boat is placed within the guide groove 10. The magnetic boat loading and unloading fixing rod 8 is suspended above the guide groove 10 by a crossbar. When the push rod 7 is pulled backward, the fixing rod can block the magnetic boat and keep it stationary, forming a relative movement between the magnetic boat and the push rod 7, thereby realizing the automatic ejection of the old magnetic boat by the new magnetic boat and its placement. Since the position of the fixing rod is limited to a suitable position above the push rod 7 by the support frame 11, the stability and repeatability of the blocking action are ensured.

[0041] The support frame 11 adopts a straddle structure with horizontal and vertical bars. On the one hand, it can accurately install the magnetic boat loading and unloading fixing rod 8 above the guide groove 10 without interfering with the movement of the push rod 7. On the other hand, the detachable connection means that this component can be easily and independently removed without affecting the overall structure of the base 4 and the push rod 7 if replacement or maintenance is required after long-term use. This design not only ensures the reliability and efficiency of automatic loading and unloading of magnetic boats, but also improves the maintainability and safety of the equipment, avoiding the risk of burns caused by manual handling of high-temperature magnetic boats.

[0042] The implementation principle of the carbon-sulfur analyzer sample introduction device in this application embodiment is as follows: A guide groove 10 is formed on the push rod 7, and the magnetic boat is placed in it and limited and supported by the two side walls of the guide groove 10, maintaining a stable posture during the pushing process. The magnetic boat loading and unloading fixing rod 8 set on the base 4 is suspended above the guide groove 10 through the support frame 11. When the push rod 7 returns, the fixing rod blocks the magnetic boat, causing relative movement between the magnetic boat and the push rod 7, thereby realizing that the new magnetic boat automatically pushes out the old magnetic boat and completes the positioning. To prevent the high-temperature molten material from splashing, one end of the push rod 7 is covered with a splash-proof arched cover 9. The arched cover is open at both ends, forming a magnetic boat inlet on one side and a magnetic boat outlet on the other side. The magnetic boat collection tank 3 located below the outlet has a sloping structure to guide the waste magnetic boat to slide into the collection box. The collection box is slidably installed in the pull hole of the base 4 and is equipped with a handle for easy centralized cleaning. Through the synergistic effect of the above structures, this device can automatically load and unload the magnetic boat within one reciprocating cycle of the pusher 7, ensuring stable feeding and smooth withdrawal of the magnetic boat, while avoiding manual handling of the high-temperature magnetic boat, reducing safety risks, and improving sample injection efficiency and the continuity of detection.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
