Description

Technical Field

[0001] This utility model relates to the field of sampling technology for metal liquid composition detection, specifically a sampling device for metal liquid composition detection in casting. Background Technology

[0002] In the early days, molten metal was often scooped from the furnace manually using simple tools such as spoons. With the development of technology, some simple mechanical sampling devices have emerged, such as sampling spoons or sampling cups with fixed structures. Although these devices have improved sampling efficiency to some extent, they still have limitations. For example, they cannot flexibly adjust the sampling height and position, and are difficult to adapt to the sampling needs of different furnaces, different liquid levels and depths, and different states of molten metal. Because the composition of molten metal is different at each depth in the furnace, and the density of different elements in the molten metal is different, stratification will occur due to gravity during high-temperature melting, resulting in different results for subsequent molten metal composition testing.

[0003] For example, prior art application number CN210741909U provides a rapid and convenient sampling device for high-temperature molten metal. It includes a fixed rod, with a collection box fixedly connected to the bottom end of the fixed rod. The collection box has a sampling chamber inside, and a base plate is provided at the bottom of the collection box. A connecting rod is fixedly connected to the middle of the upper surface of the base plate, and the top end of the connecting rod penetrates the inner top wall of the sampling chamber and inserts into a slot. The slot is located in the middle of the inner cavity of the fixed rod. This invention, by providing a base plate at the bottom of the collection box and a return spring in a limiting groove, can tightly connect the annular protrusion on the base plate with the annular groove on the collection box, sealing the sampling chamber. This prevents molten metal from entering the sampling chamber during sample extraction, ensuring the purity of the sample from the smelting furnace and guaranteeing sampling accuracy.

[0004] Based on actual usage, the aforementioned prior art primarily prevents molten metal from entering the sampling chamber from the upper part of the smelting furnace, thus ensuring the purity and accuracy of the smelting furnace samples. However, it has been found that it cannot quickly adjust the sampling height to accommodate different metal liquid depths, ensuring that samples from different metal liquid levels can be taken, thereby improving the efficiency of subsequent metal liquid composition detection and avoiding rework or losses caused by missing samples from different metal liquid levels. Therefore, based on actual usage, we have improved the aforementioned prior art. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of this section, the abstract and the title of this utility model. Such simplifications or omissions shall not be used to limit the scope of this utility model.

[0006] In view of the problems existing in the above and / or prior art, the present invention is proposed.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sampling device for detecting the composition of molten metal in casting includes a splash guard, a height adjustment component, a sampling component, a sampling tube, and a hollow sleeve.

[0009] A height adjustment component is installed at the top of the outer wall of the splash guard;

[0010] The splash guard is slidably connected to the side wall of the height adjustment component, and a hollow sleeve is provided on the bottom outer side wall of the splash guard.

[0011] A sampling tube is provided on the outer wall of the bottom actuator of the height adjustment component.

[0012] Furthermore: The height adjustment assembly includes a mounting housing located on the top of the outer wall of the splash guard. Worms are slidably connected to both sides of the inner cavity of the mounting housing. One end of the worm extends to one side of the outer wall of the mounting housing, and a rotating handle is located adjacent to one end of the worm on the outer wall of the mounting housing. A matching worm wheel meshes with one side of the worm, and a lead screw is embedded in the middle side wall of the worm wheel. One bottom end of the lead screw is rotatably connected to the bottom side wall of the splash guard, and the bottom end of the lead screw extends to the bottom outer wall of the splash guard. A matching hollow sliding tube is threadedly connected to the outer wall of the lead screw. The outer wall of the hollow sliding tube is slidably connected to the inner side wall of the hollow sleeve. A limiting circular block is located on the outer wall of the bottom end of the lead screw, and a fixing component is located at one end of the outer wall of the mounting housing.

[0013] Furthermore: the fastener includes a bottom clamp plate disposed at one end of the outer wall of the mounting housing, a slider disposed on one side of the top of the bottom clamp plate, a movable clamp plate slidably connected to one side wall of the slider, and a screw rod rotatably connected to the bottom clamp plate adjacent to the top side wall of the slider, and the top side wall of the movable clamp plate threadedly connected to the screw rod.

[0014] Furthermore: the sampling tube includes a sliding plate disposed on the outer side wall of the bottom of the hollow sliding tube, a sampling through tube disposed at the bottom of the sliding plate, four sets of liquid inlets with the same structure are arranged in a ring array on the outer side wall of the top end of the sampling through tube, and a filter screen circular support is threadedly connected to the inner side wall of the bottom end of the sampling through tube adjacent to the liquid inlet.

[0015] Furthermore: the layout component includes a sliding pressing rod slidably connected to the side wall of the splash guard adjacent to the height adjustment component. A spring is provided on the outer side wall of the top end of the sliding pressing rod adjacent to the splash guard, and a base plate is provided on the outer side wall of the bottom end of the sliding pressing rod. A matching closed circular head is provided on the top of the base plate adjacent to the outer side wall of the bottom end of the sampling through tube.

[0016] Furthermore: the circular support for the filter screen includes a ceramic fiber filter screen disposed on its inner side wall.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through its height adjustment component, allows for quick height adjustment during sampling to adapt to different metal liquid depths, ensuring that samples from different metal liquid levels can be collected. This improves the efficiency of subsequent metal liquid composition detection, avoids rework or losses caused by missing samples from different metal liquid levels, and is easy to operate with a simple structure. Specifically, the operator manually rotates the bottom clamp plate, which is connected to a screw on the outer wall of the top side of the slider. This causes the moving clamp plate to move towards the bottom clamp plate on the outer wall of the slider's actuator end, providing support and closing. The moving clamp plate and the bottom clamp plate are then clamped against the side wall of the furnace or smelting furnace for initial fixation, preventing sampling vibration and providing a splash guard. To prevent molten slag from splashing and to isolate the area, a handle located adjacent to one end of the worm gear on the outer wall of the mounting housing is manually rotated. This worm gear is supported and rotated on both sides of the slidingly connected inner cavity of the mounting housing. The rotation of the worm gear drives a matching worm wheel on one side to rotate. The rotation of the worm wheel drives a lead screw embedded in the middle side wall. One end of the lead screw is rotatably connected to the bottom side wall of the splash guard, supporting rotation within the hollow sleeve cavity. The rotation of the lead screw drives a matching hollow sliding tube threaded to the outer wall, allowing for vertical movement adjustment within the slidingly connected hollow sleeve cavity. A sliding plate is also slidably connected to the outer wall of the sliding pressing rod to facilitate vertical movement adjustment. A sampling through-tube is located at the bottom of the sliding plate, through which the upper part of the hollow sliding tube passes. The adjustable height of the moving part accommodates different metal liquid level sampling depths. Four identical inlets are arranged in a ring array on the outer wall of the top end of the sampling through-tube, allowing the molten metal to enter the ceramic fiber filter screen installed on the inner wall of the circular filter support for filtration of molten metal slag. This ceramic fiber filter screen is designed to withstand high temperatures for extended periods, preventing it from melting or carbonizing and failing, thus ensuring the molten metal sample is stored in the sampling through-tube. The filter screen support is threaded to the inner wall of the sampling through-tube adjacent to the bottom of the inlet, facilitating disassembly or replacement when testing for slag content in the molten metal. The operator manually rotates the screw to detach the moving clamp and bottom clamp from the side wall of the furnace or smelting furnace, allowing for the conveying of metal... When sampling liquid samples, the operator manually presses and slides the sliding rod downwards along the side wall of the splash guard adjacent to the height adjustment component. Then, by manually rotating the circular block at the top of the sliding rod, the square locking block disengages from the handle limiting groove on the top of the mounting housing. Simultaneously, the spring is compressed by the pressure of the circular block against the outer wall of the splash guard. This causes the sliding rod to move a matching closed circular head, located on the outer wall of the bottom end of the sampling tube adjacent to the bottom of the tube, away from the bottom of the tube. Because the sampling tube is hollow at both ends, the sampled liquid metal is poured into the instrument for component analysis.Next, by manually rotating and sliding the circular block at the top of the rod, the square locking block on the circular block rotates into the handle limiting groove on the top of the mounting housing. Manually releasing the circular block at the top of the rod allows the spring to rebound and engage with the handle limiting groove on the top of the mounting housing for fixation. The spring's rebound force ensures the closed circular head better abuts against the bottom of the sampling tube, preventing leakage of molten metal and potential safety hazards. This operation allows for quick height adjustment during sampling to accommodate different molten metal depths, ensuring that samples from different molten metal levels can be collected. This improves the efficiency of subsequent molten metal composition detection and avoids rework or losses due to missing samples of different molten metal levels. The operation is convenient and the structure is simple.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a sampling device for detecting the composition of molten metal in casting, including a splash guard 1, a height adjustment component 2, a sampling component 3, a sampling tube 4, and a hollow sleeve 5;

[0031] A height adjustment component 2 is provided on the top of the outer wall of the splash guard 1;

[0032] The splash guard 1 is slidably connected to the side wall of the height adjustment component 2 with a layout component 3, and the bottom outer side wall of the splash guard 1 is provided with a hollow sleeve 5;

[0033] The height adjustment component 2 has a sampling tube 4 on the outer wall of the bottom execution end. This utility model allows for quick height adjustment during sampling through the height adjustment component 2, which can adapt to different metal liquid level sampling depths. This ensures that samples of different metal liquid levels can be sampled, improves the efficiency of subsequent metal liquid composition detection, and avoids rework or loss caused by the lack of samples of different metal liquid levels. It is easy to operate and has a simple structure.

[0034] Preferably, the height adjustment component 2 includes a mounting shell 21 disposed on the top of the outer wall of the splash guard 1. Worms 24 are slidably connected to both sides of the inner cavity of the mounting shell 21. One end of the worm 24 extends to one side of the outer wall of the mounting shell 21, and a rotating handle 23 is provided adjacent to one side of the outer wall of the mounting shell 21 at one end of the worm 24. A matching worm wheel 25 meshes with one side of the worm 24. A lead screw 22 is embedded in the middle side wall of the worm wheel 25. One bottom end of the lead screw 22 is rotatably connected to the bottom side wall of the splash guard 1, and the bottom end of the lead screw 22 extends to the bottom outer wall of the splash guard 1. A matching hollow sliding tube 27 is threadedly connected to the outer wall of the lead screw 22. The outer wall of the hollow sliding tube 27 is slidably connected to the inner side wall of the hollow sleeve 5. A limiting circular block 28 is provided on the outer wall of the bottom end of the lead screw 22. A fixing member 26 is provided at one end of the outer wall of the mounting shell 21. The height adjustment component can be adjusted by manual rotation. A rotating handle 23 is provided on one end of the worm gear 24 adjacent to the outer wall of the mounting shell 21, which drives the worm gear 24 to rotate and be supported by the two side walls of the inner cavity of the mounting shell 21, which are slidably connected. The rotation of the worm gear 24 drives the matching worm wheel 25 to rotate on one side. The rotation of the worm wheel 25 drives the lead screw 22 embedded in the middle side wall to rotate and be supported by the bottom end of the lead screw 22 to rotate and be supported by the bottom side wall of the splash guard 1 in the inner cavity of the hollow sleeve 5. The rotation of the lead screw 22 drives the matching hollow sliding round tube 27 threadedly connected to the outer wall to move up and down and adjust the height of the hollow sleeve 5. The sliding plate 41 is also slidably connected to the outer wall of the sliding pressing round rod 31 to facilitate the adjustment of the height of the movement. The bottom of the sliding plate 41 is provided with a sampling through tube 42, which can be adjusted by the height of the hollow sliding round tube 27 to adapt to different metal liquid level depths for sampling.

[0035] Preferably, the fixing member 26 includes a bottom clamping plate 261 disposed at one end of the outer wall of the mounting shell 21. A slider 264 is disposed on the outer wall of the top side of the bottom clamping plate 261. A movable clamping plate 263 is slidably connected to one side wall of the slider 264. A screw 262 is rotatably connected to the outer wall of the top side of the bottom clamping plate 261 adjacent to the slider 264. The top side wall of the movable clamping plate 263 is threadedly connected to the screw 262. By manually rotating the screw 262 rotatably connected to the outer wall of the top side of the bottom clamping plate 261 adjacent to the slider 264, the movable clamping plate 263 is driven to move and close towards the bottom clamping plate 261 on the outer wall of the slidingly connected slider 264 at the execution end. This allows the movable clamping plate 263 and the bottom clamping plate 261 to clamp onto the side wall of the furnace or smelting furnace for initial fixation, preventing sampling shaking.

[0036] Preferably, the sampling tube 4 includes a sliding plate 41 disposed on the outer side wall of the bottom of the hollow sliding tube 27. A sampling through tube 42 is disposed at the bottom of the sliding plate 41. Four sets of liquid inlets 44 with the same structure are arranged in an annular array on the outer side wall of the top end of the sampling through tube 42. A filter screen circular support 43 is threadedly connected to the inner side wall of the bottom end of the sampling through tube 42 adjacent to the liquid inlets 44. The molten metal enters the filter screen circular support 43, including the ceramic fiber filter screen 431 disposed on the inner side wall, through the four sets of liquid inlets 44 with the same structure arranged in an annular array on the outer side wall of the top end of the sampling through tube 42 for filtration of molten metal slag.

[0037] Preferably, the sampling component 3 includes a sliding pressing rod 31 slidably connected to the side wall of the splash guard 1 adjacent to the height adjustment component 2. A spring 32 is provided on the outer wall of the top end of the sliding pressing rod 31 adjacent to the splash guard 1, and a base plate 33 is provided on the outer wall of the bottom end of the sliding pressing rod 31. A matching closed circular head 34 is provided on the top of the base plate 33 adjacent to the outer wall of the bottom end of the sampling through pipe 42. By manually rotating the screw 262, the operator disengages the moving clamp 263 and the bottom clamp 261 from the side wall of the furnace or smelting furnace. When conveying molten metal samples, the operator manually presses the sliding pressing rod 31 on the side wall of the splash guard 1 adjacent to the height adjustment component. 2. The side wall slides downwards, and then the circular block at the top of the sliding pressing rod 31 is manually rotated. The square locking block set on the circular block at the top of the sliding pressing rod 31 is rotated away from the handle limiting groove set on the top of the mounting shell 21. At the same time, the spring 32 is compressed by the pressure of the circular block at the top of the sliding pressing rod 31 against the outer wall of the top of the splash baffle 1. The sliding pressing rod 31 drives the bottom plate 33 to move away from the bottom of the sampling tube 42. The matching closed circular head 34 set on the outer wall of the bottom end of the bottom of the sampling tube 42 is located at the top of the bottom plate 33. Since the upper and lower ends of the sampling tube 42 are hollow and connected, the sampled liquid metal is poured out into the instrument for detecting the components.

[0038] Preferably, the circular support 43 for the filter screen includes a ceramic fiber filter screen 431 disposed on its inner sidewall, and the ceramic fiber filter screen 431 has the ability to withstand high temperatures for a long time.

[0039] Example: At the start of work, the operator manually rotates the screw 262 connected to the outer wall of the bottom clamping plate 261 adjacent to the top of the slider 264, which drives the moving clamping plate 263 to move towards the bottom clamping plate 261 on the outer wall of the sliding slider 264. This provides support and closes the moving clamping plate 263 and the bottom clamping plate 261, clamping them onto the side wall of the furnace or smelting furnace for initial fixation, preventing sampling from shaking, and isolating the molten slag from splashing through the anti-splash baffle 1.

[0040] Then, by manually rotating one end of the worm gear 24, which is adjacent to the outer wall of the mounting shell 21, a rotating handle 23 is provided to drive the worm gear 24 to rotate and support the rotation of the two side walls of the inner cavity of the mounting shell 21, which are slidably connected. The rotation of the worm gear 24 drives the matching worm wheel 25 to rotate on one side. The rotation of the worm wheel 25 drives the lead screw 22 embedded in the middle side wall to rotate and support the rotation of the hollow sleeve 5, which is rotatably connected to the bottom side wall of the splash guard 1. The rotation of the lead screw 22 drives the matching hollow sliding round tube 27, which is threaded to the outer wall, to move up and down and adjust the height of the sliding plate 41 on the inner wall of the hollow sleeve 5. The sliding plate 41 is also slidably connected to the outer wall of the sliding pressing round rod 31 to facilitate the adjustment of the height of the sliding plate 41. The bottom is equipped with a sampling through-tube 42. The height of the hollow sliding tube 27 can be adjusted to adapt to different metal liquid depths for sampling. Four sets of liquid inlets 44 with the same structure are opened in a ring array on the outer side wall of the top end of the sampling through-tube 42, so that the metal liquid enters the ceramic fiber filter screen 431 set on the inner side wall of the filter screen circular support 43 for filtering of molten metal slag. The ceramic fiber filter screen 431 can withstand high temperature for a long time, avoiding the filter screen from melting or carbonizing due to high temperature. The metal liquid sample enters the sampling through-tube 42 for storage. The filter screen circular support 43 is threaded to the inner side wall of the bottom end of the sampling through-tube 42 adjacent to the liquid inlet 44, so that it can be disassembled or replaced when it is necessary to detect the amount of molten metal in the liquid.

[0041] Furthermore, by manually rotating the screw 262, the operator disengages the moving clamp 263 and the bottom clamp 261 from the side wall of the furnace or smelting furnace. When conveying molten metal samples, the operator manually presses the sliding pressing rod 31 to slide it downwards on the side wall adjacent to the height adjustment component 2 of the slidingly connected splash guard 1. Then, by manually rotating the round block at the top of the sliding pressing rod 31, the square locking block on the round block at the top of the sliding pressing rod 31 moves away from the handle limiting groove on the top of the mounting shell 21. At the same time, the spring 32 is compressed by the pressure of the round block at the top of the sliding pressing rod 31 against the outer wall of the top of the splash guard 1. This causes the sliding pressing rod 31 to move the matching closed round head 34, which is located on the outer wall of the bottom end of the bottom of the sampling through pipe 42, away from the bottom of the sampling through pipe 42. The hollow, through-hole design allows the sampled molten metal to be poured into the instrument for component detection. Then, by manually rotating and sliding the circular block at the top of the sliding rod 31, a square locking block is moved into a handle-limiting groove on the top of the mounting housing 21. This allows the circular block at the top of the sliding rod 31 to be manually released, causing the spring 32 to rebound and engage with the handle-limiting groove on the top of the mounting housing 21 for fixation. The rebound force of the spring 32 also ensures that the closed circular head 34 is better engaged and closed at the bottom of the sampling through-tube 42, preventing molten metal leakage and potential safety hazards. This operation allows for quick height adjustment during sampling to accommodate different molten metal depths, ensuring that samples of different molten metal levels can be collected. This improves the efficiency of subsequent molten metal component detection and avoids rework or losses due to missing samples of different molten metal levels. The operation is convenient and the structure is simple.

[0042] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
