Description

Technical Field

[0001] This utility model relates to the field of molten iron sampling technology, specifically an extended molten iron sampler. Background Technology

[0002] As is well known, during the blast furnace ironmaking process, it is necessary to sample and analyze the composition of the molten iron in the blast furnace to control the ironmaking progress and ensure the quality of the blast furnace ironmaking. In this process, molten iron samplers are often used and are widely used in the field of blast furnace ironmaking.

[0003] According to a published description of a molten iron sampler (publication number: CN217132636U), it is easy to operate with one hand, simple to operate, and requires minimal effort due to its small operating range. This allows the operator to use their other hand, improving safety and making it highly practical. Furthermore, it allows for easy extension of the L-shaped connecting rod to sample molten iron from deeper locations, and the extension length is adjustable. The sampler includes two sampling blocks, each equipped with an L-shaped connecting rod. Both L-shaped connecting rods are connected to a connecting rod via a telescopic mechanism. Each connecting rod is fixedly connected to a handle via a rotating plate. The two rotating plates rotate in conjunction with a fixed circular plate. The telescopic mechanism includes a top plate, which is fixedly connected to the connecting rod. A screw and multiple guide rods are rotatably connected to the top plate. A movable plate is threaded onto the screw, and the multiple guide rods slide in conjunction with the movable plate. The movable plate is fixedly connected to the L-shaped connecting rod.

[0004] The aforementioned device, which uses components such as a sampling block and an L-shaped connecting rod to work together, exposes the molten iron to the air for an extended period during sampling and testing. This can lead to the entrapment of gas or slag, resulting in porosity or inclusions in the sample, which requires improvement. Utility Model Content

[0005] The purpose of this invention is to provide an extended molten iron sampler to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extended molten iron sampler, comprising a sampling mechanism, the sampling mechanism including a sampling spoon, a support rod fixedly connected to the outer surface of the sampling spoon, a handle fixedly connected to the end of the support rod away from the sampling spoon, and a through hole at the bottom of the sampling spoon; further comprising a sealing mechanism for preventing material spillage; and a diversion mechanism for improving working efficiency; the sealing mechanism includes a connecting rod A, a positioning rod passing through one side of the connecting rod A and fixedly connected to the connecting rod A.

[0007] Furthermore, the sealing mechanism also includes a fixing frame A, one end of which is fixedly connected to one side of the support rod. A fixing rod is fixedly connected to the end of the fixing frame A away from the support rod. The end of the fixing rod away from the fixing frame A passes through the connecting rod A and is rotatably connected to the connecting rod A. A torsion spring is fixedly sleeved on the outer surface of the fixing rod. One end of the torsion spring is fixedly connected to the side of the connecting rod A near the positioning rod. The other end of the torsion spring is fixedly connected to the fixing frame A. A cover plate is fixedly connected to one end of the connecting rod A. A sliding groove is formed on the outer surface of the handle. A spring is fixedly connected to the inner wall of the sliding groove. A locking block is fixedly connected to the end of the spring away from the inner wall of the sliding groove.

[0008] Furthermore, one end of the locking block is provided with an inclined surface, and the end of the locking block away from the inclined surface is slidably connected to the inner wall of the groove, and the locking block is located below the connecting rod A.

[0009] Furthermore, the drainage mechanism includes a fixed frame B, with the end of the positioning rod away from the connecting rod A passing through the fixed frame B and rotatably connected to the fixed frame B. The end of the fixed frame B away from the connecting rod A is fixedly connected to the connecting rod B, and the end of the connecting rod B away from the fixed frame B is fixedly connected to a blocking block.

[0010] Furthermore, there are two fixing frames B, which are symmetrical to each other along the vertical central axis of the connecting rod B. The fixing frame B is L-shaped, and the through hole is located on the displacement trajectory of the plug.

[0011] Furthermore, the connecting rod B is located below the support rod, the connecting rod B is located below the sampling spoon, and the positioning rod is located between the two fixing brackets B.

[0012] Furthermore, the cover plate is located above the sampling spoon, the fixing rod and the positioning rod are located on the same horizontal line, and the inclined surface of the locking block is located on the displacement trajectory of the connecting rod A away from the cover plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By linking the sealing mechanism with the flow guiding mechanism, after the sampling spoon is filled with molten iron, the operator can press the connecting rod A with one hand to simultaneously drive the cover plate to tightly cover the sampling spoon opening and move the blocking block upward to block the bottom hole of the spoon, forming a double seal. This effectively isolates air and prevents slag from being drawn in, thereby significantly reducing the risk of defects such as porosity or slag inclusion in the sample during the transfer process, and ensuring the accuracy and representativeness of the sampling and testing.

[0014] The extended structure, consisting of a handle and a support rod, along with the clever combination of a slide, spring, and locking block, allows the mechanism to automatically lock after the operator completes the sealing action. The entire process is characterized by small operating range, low effort, and stable reliability, truly achieving convenient one-handed operation. This frees up the operator's other hand to maintain balance or deal with emergencies, greatly improving operational safety in dangerous environments such as high-temperature molten iron ladles.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0018] This utility model provides a technical solution: such as Figure 1 - Figure 5An extended molten iron sampler is shown, comprising a sampling mechanism 1, which includes a sampling spoon 101. A support rod 102 is fixedly connected to the outer surface of the sampling spoon 101, and a handle 103 is fixedly connected to the end of the support rod 102 away from the sampling spoon 101. A through hole 104 is provided at the bottom of the sampling spoon 101. The sampler also includes a sealing mechanism 2 to prevent material spillage and a diversion mechanism 3 to improve working efficiency. The sealing mechanism 2 includes a connecting rod A203, and a positioning rod 301 passes through one side of the connecting rod A203 and is fixedly connected to the connecting rod A203.

[0019] The sealing mechanism 2 also includes a fixing frame A201. One end of the fixing frame A201 is fixedly connected to one side of the support rod 102. A fixing rod 202 is fixedly connected to the end of the fixing frame A201 away from the support rod 102. The end of the fixing rod 202 away from the fixing frame A201 passes through the connecting rod A203 and is rotatably connected to the connecting rod A203. A torsion spring 204 is fixedly sleeved on the outer surface of the fixing rod 202. One end of the torsion spring 204 is fixedly connected to the side of the connecting rod A203 near the positioning rod 301. The other end of the torsion spring 204 is fixedly connected to the fixing frame A201. A cover plate 205 is fixedly connected to one end of the connecting rod A203. A groove 206 is opened on the outer surface of the handle 103. A spring 207 is fixedly connected to the inner wall of the groove 206. A locking block 208 is fixedly connected to the end of the spring 207 away from the inner wall of the groove 206.

[0020] One end of the locking block 208 is provided with an inclined surface, and the end of the locking block 208 away from the inclined surface is slidably connected to the inner wall of the slide groove 206. The locking block 208 is located below the connecting rod A203.

[0021] The drainage mechanism 3 includes a fixed frame B302. The end of the positioning rod 301 away from the connecting rod A203 passes through the fixed frame B302 and is rotatably connected to the fixed frame B302. The end of the fixed frame B302 away from the connecting rod A203 is fixedly connected to the connecting rod B303, and the end of the connecting rod B303 away from the fixed frame B302 is fixedly connected to the blocking block 304.

[0022] There are two fixing brackets B302, which are symmetrical to each other along the vertical central axis of the connecting rod B303. The fixing brackets B302 are L-shaped, and the through hole 104 is located on the displacement trajectory of the block 304.

[0023] The connecting rod B303 is located below the support rod 102 and below the sampling spoon 101. The positioning rod 301 is located between the two fixing brackets B302.

[0024] The cover plate 205 is located above the sampling spoon 101, the fixing rod 202 and the positioning rod 301 are on the same horizontal line, and the inclined surface of the locking block 208 is located on the displacement trajectory of the connecting rod A203 away from the cover plate 205.

[0025] Working principle: The operator holds the handle 103 and inserts the sampling spoon 101 into the molten iron to take a sample. Before sampling, the sealing mechanism 2 is in standby mode: under the preload of the torsion spring 204, the connecting rod A203 drives the cover plate 205 at its end to remain open, so that the mouth of the sampling spoon 101 is open. At the same time, the positioning rod 301, which is fixedly connected to the connecting rod A203, drives the flow guiding mechanism 3 at its other end to be in the ready position, that is, the block 304 at one end of the connecting rod B303 leaves the through hole 104 at the bottom of the sampling spoon 101.

[0026] After the sampling spoon 101 is filled with molten iron and lifted out of the liquid, the operator presses down on the end of the connecting rod A203 away from the cover plate 205. The connecting rod A203 rotates around the fixed rod 202, overcoming the torque of the torsion spring 204, and drives the cover plate 205 to rotate downward, finally tightly covering the mouth of the sampling spoon 101, forming a seal. This effectively prevents the molten iron from splashing or spilling during movement, ensuring operational safety. Since the positioning rod 301 is fixedly connected to the connecting rod A203, pressing down on the connecting rod A203 will synchronously drive the positioning rod 301 to rotate. The positioning rod 301 drives the fixed frame B302, which is rotated to it, causing the connecting rod B303 at the other end of the fixed frame B302 to swing upward, thereby precisely pushing the blocking block 304 to move upward, blocking the through hole 104 at the bottom of the sampling spoon 101, forming a second seal, further ensuring the airtightness of the sampling spoon 101. Pressing down on the connecting rod A203... During the process, its end will contact the inclined surface of the locking block 208, and the locking block 208 will be squeezed by the guiding action of the inclined surface, causing the locking block 208 to compress the spring 207 in the slide groove 206 behind it and retract into the slide groove 206. When the connecting rod A203 passes the highest point of the locking block 208, the compressed spring 207 pushes the locking block 208 to reset and pop out. At this time, the connecting rod A203 is locked by the locking block 208, so that the entire device is stable in a sealed state, that is, the cover plate 205 is closed and the plug 304 blocks the through hole 104, which makes it easy for the operator to hold and transfer the sample safely. When it is necessary to pour out the sample, simply press or move the locking block 208 again to release the connecting rod A203. Under the strong restoring force of the torsion spring 204, the connecting rod A203 quickly rebounds to the initial position, driving the cover plate 205 to open. At the same time, the plug 304 is opened by the drainage mechanism 3. Once the molten iron sample leaves the through hole 104, it can flow out smoothly, completing the entire sampling and unloading process. This design, through a clever connecting rod and buckle structure, enables the sealing and opening to be completed with one hand or simple operation, improving the efficiency and safety of sampling.
