Description

Technical Field

[0001] This utility model relates to a sampling device, and more particularly to a sampling device for the zinc and zinc alloy casting process. Background Technology

[0002] Currently, chemical composition analysis of zinc and zinc alloy products requires sampling before analysis. Existing sampling methods primarily involve mechanically crushing the product after cooling and solidification. This involves molten zinc and zinc alloy produced in an electric arc furnace, which is then transported to the casting station via a ladle. The molten liquid is poured into a chute at the casting station, flowing down into a zinc and zinc alloy ingot mold on a moving trolley for casting. After cooling, analysts use a hammer to break the ingot according to the sampling standard points and extract the analytical samples. This method has the following problems: 1. Sampling time is delayed. The zinc and zinc alloy molten liquid requires a long time to cool from high temperature to room temperature after casting, resulting in poor timeliness of analysis results for production guidance. 2. The ingot solidified in the zinc and zinc alloy mold exhibits significant compositional segregation. Analysis results vary greatly depending on the sampling location, leading to significant deviations in production guidance and potentially causing large fluctuations in the smelting process. Utility Model Content

[0003] The purpose of this invention is to provide a sampling device for the zinc and zinc alloy casting process that has a simple structure, improves sampling efficiency, and provides high accuracy in analysis results.

[0004] This utility model is implemented by the following technical solution: The purpose of this patent is to provide a sampling device in the zinc and zinc alloy casting process, wherein a fixed frame is provided below the chute; a fixed seat is slidably provided on the fixed frame, and a first telescopic rod that extends and retracts along the flow direction of the alloy liquid in the chute is fixed on the fixed frame, and the telescopic end of the first telescopic rod is fixedly connected to the fixed seat; a sample receiving groove is provided on the fixed seat through a support frame, one end of the sample receiving groove extends beyond the edge of the fixed seat and is located below the discharge port of the chute, and a sample receiving pot is placed on the fixed seat below the other end of the sample receiving groove.

[0005] Furthermore, a fixed shell is fixed at the top of the support frame, which slopes downward from the chute to the sample receiving pot. The fixed shell has an arc-shaped cross-section, and the sample receiving groove is movably engaged within the fixed shell.

[0006] Furthermore, a clamping plate is fixed above the two side walls of the fixed shell to engage the sample receiving groove; several blind holes are opened at the bottom of the sample receiving groove, and threaded holes corresponding to the blind holes are opened at the bottom of the fixed shell. A bolt is screwed into each of the threaded holes, and the tip of the bolt is movably inserted into the blind hole.

[0007] Furthermore, at least two parallel guide rods are fixed on the fixed frame, and a sliding sleeve matching the guide rods is fixed at the bottom of the fixed base, the sliding sleeve being movably fitted onto the guide rods.

[0008] Furthermore, it also includes a sample receiving platform, which is slidably disposed on the fixed base. A second telescopic rod is horizontally fixed on the fixed base and is perpendicular to the first telescopic rod. The telescopic end of the second telescopic rod is fixedly connected to the side of the sample receiving platform. The support frame is fixed on the sample receiving platform, and the sample receiving pot is placed on the sample receiving platform.

[0009] Furthermore, at least one groove is provided on the fixed base, and a slider matching the groove is fixed at the bottom of the sample receiving platform, and the slider is slidably disposed in the groove.

[0010] Furthermore, both the sample receiving groove and the sample receiving pot are made of graphite.

[0011] Furthermore, the sample receiving pot body is a frustum shape with a larger top and a smaller bottom, and a bracket ring is fitted on the outer side of the sample receiving pot body, with a handle fixed to the outer wall of the bracket ring.

[0012] Advantages of this utility model: 1. This utility model has a simple structure and is easy to implement. The fixed seat is controlled to move towards the discharge port of the chute by the first telescopic rod, so that the sample receiving tank can collect a small amount of the zinc and zinc alloy liquid being cast. Then, the first telescopic rod is controlled to retract, which drives the sample receiving tank away from below the discharge port of the chute to stop collecting samples. The laboratory personnel take out the sample receiving pot and test and analyze the zinc and zinc alloy samples inside. The whole sampling process is simple and improves the sampling efficiency, which in turn improves the production efficiency. Moreover, there is no need to wait for the zinc and zinc alloy liquid to cool and solidify before crushing and sampling, which reduces the sampling time and ensures the timeliness of the analysis results for production guidance.

[0013] 2. The sample receiving tank and sample receiving pot are made of graphite material, which does not chemically react with the high-temperature zinc and zinc alloy liquid, effectively controlling the content of impurities introduced during sampling and ensuring the accuracy of the test results.

[0014] 3. Directly connecting zinc and zinc alloy liquid for analysis avoids the problem of component segregation after casting and inaccurate sampling points leading to large errors in analysis results. The analysis results are highly accurate and play a significant role in guiding production. Attached Figure Description

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-4 As shown, the technical solution adopted by this utility model is as follows: a sampling device for the zinc and zinc alloy casting process, wherein a fixed frame 2 and a sample receiving platform 3 are provided below the chute 1; a fixed seat 4 is slidably provided on the fixed frame 2, and a first telescopic rod 5 that extends and retracts along the flow direction of the alloy liquid in the chute 1 is fixed on the fixed frame 2, and the telescopic end of the first telescopic rod 5 is fixedly connected to the fixed seat 4; a sample receiving platform 3 is slidably provided on the fixed seat 4, and a second telescopic rod 6 that is horizontally fixed on the fixed seat 4 and perpendicular to the first telescopic rod 5, and the telescopic end of the second telescopic rod 6 is fixedly connected to the side of the sample receiving platform 3; a sample receiving groove 8 is provided on the sample receiving platform 3 through a support frame 7, one end of the sample receiving groove 8 extends beyond the edge of the sample receiving platform 3 and is placed below the discharge port of the chute 1, and a sample receiving pot 9 is placed on the sample receiving platform 3 below the other end of the sample receiving groove 8; both the sample receiving groove 8 and the sample receiving pot 9 are made of graphite, which does not chemically react with the high-temperature zinc and zinc alloy liquid, effectively controlling the impurity content introduced during sampling and ensuring the accuracy of the test results.

[0026] A fixed shell 10 is fixed at the top of the support frame 7, which slopes downward from the chute 1 to the sample receiving pot body 9. The cross-sectional shape of the fixed shell 10 is arc-shaped. The sample receiving groove 8 is movably snapped into the fixed shell 10. A snapping plate 11 is fixed above the two side walls of the fixed shell 10 to snap into the sample receiving groove 8. Several blind holes 81 are opened at the bottom of the sample receiving groove 8. Threaded holes 101 corresponding to the blind holes 81 are opened at the bottom of the fixed shell 10. A bolt 12 is screwed into each threaded hole 101. The tip of the bolt 12 is movably inserted into the blind hole 81 to fix the sample receiving groove 8.

[0027] At least two parallel guide rods 13 are fixed on the fixed frame 2. A sliding sleeve 14 matching the guide rods 13 is fixed at the bottom of the fixed base 4. The sliding sleeve 14 is movably sleeved on the guide rods 13. At least one sliding groove 41 is opened on the fixed base 4. A slider 15 matching the sliding groove 41 is fixed at the bottom of the sample receiving platform 3. The slider 15 is slidably disposed in the sliding groove 41.

[0028] The sample receiving pot body 9 is a frustum shape with a larger top and a smaller bottom. A bracket ring 16 is fitted on the outside of the sample receiving pot body 9, and a handle 17 is fixed on the outer wall of the bracket ring 16 to facilitate the laboratory personnel to take the sample receiving pot body 9.

[0029] Working principle: like Figure 5 As shown, when the molten zinc and zinc alloy in the ladle flows through the chute 1 into the zinc and zinc alloy sample mold on the moving trolley, the laboratory personnel control the first telescopic rod 5 to extend, pushing the fixed seat 4 towards the discharge port of the chute 1, so that the sample receiving trough 8 can collect a small amount of the alloy being cast. Then, the first telescopic rod 5 is controlled to retract, moving the sample receiving trough 8 away from below the discharge port of the chute 1 to stop receiving samples. Next, the second telescopic rod 6 is controlled to extend, pushing the sample receiving platform 3 towards one side of the chute 1, so that the sample receiving pot 9 is away from below the chute 1, making it easier for the laboratory personnel to remove the sample receiving pot 9. After the sample receiving pot 9 is away from below the chute 1, the laboratory personnel remove the sample receiving pot 9. The sample is removed from the receiving platform 3 and placed in a spare receiving pot 9. The zinc and zinc alloy samples in the receiving pot 9 are then rapidly cooled before testing and analysis. The entire sampling process is simple, improving sampling efficiency, which in turn improves production efficiency. Furthermore, it eliminates the need to wait for all the alloy liquid in the zinc and zinc alloy ingot mold to cool and solidify before crushing and sampling, reducing sampling time and ensuring the timeliness of analysis results for production guidance. Directly collecting the alloy liquid for testing and analysis avoids the situation where compositional segregation occurs after casting and molding, and large errors in analysis results are caused by inaccurate sampling points. The test and analysis results are highly accurate and play a significant role in guiding production.
