Description

Technical Field

[0001] The utility model relates to the technical field of aluminum ingot casting, in particular to a sampling device for detecting the composition of molten aluminum in a furnace. Background Technique

[0002] Aluminum ingot casting is a process of heating aluminum alloy or pure aluminum to a liquid state and then pouring it into a pre-designed mold through casting to make it cool and solidify. Aluminum ingot casting is usually used to produce various aluminum alloy parts and products, which are widely used in industries such as industry, aerospace, automotive, construction, and consumer goods manufacturing. According to application requirements, during the melting process of aluminum alloy, it is necessary to detect and analyze the chemical composition of the melt in the furnace, and adjust the composition of the melt in the furnace appropriately according to the analysis results. Usually, a sampling spoon is used to sample the molten aluminum in the furnace. After the molten aluminum is taken out, it is cast and solidified into an ingot in a specific mold, and then the aluminum alloy ingot is machined into chips and analyzed for chemical composition using a direct-reading spectrometer.

[0003] However, in the prior art, sampling with a sampling spoon first has the following problems. One is that the existing sampling spoon cannot determine the sampling depth and cannot obtain the molten aluminum sample liquid at a specific depth. The other is that, due to the simple open structure of the existing sampling spoon, when the sample liquid is taken out after sampling at a certain position, it will contact the molten aluminum at other positions, resulting in a certain error in the sampled sample liquid. Summary of the Invention

[0004] In view of the above problems, the utility model provides a sampling device for detecting the composition of molten aluminum in a furnace.

[0005] To achieve the above object, the utility model adopts the following technical scheme:

[0020] To further understand the purpose, structure, characteristics, and functions of the present utility model, the following is a detailed description in conjunction with embodiments.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 , a sampling device for detecting the composition of molten aluminum in a furnace according to an embodiment of the present utility model includes a sampling bucket 100, a handle 200, an adjusting rod 300, a pull rod 400, and a sealing plug 500. The upper and lower ends of the sampling bucket 100 are open, and a scale 110 is provided on the outer side wall of the sampling bucket 100; one end of the handle 200 is fixedly connected to the upper end of the sampling bucket 100. The adjusting rod 300 is hinged to the handle 200 on the side close to the sampling bucket. The adjusting rod 300 is also connected by an elastic component 600 behind the hinged position with the handle 200. One end of the adjusting rod 300 facing the sampling bucket 100 is rotatably connected to the upper end of the pull rod 400 through a pin shaft. The pull rod 400 is arranged along the central axis of the sampling bucket 100. The lower end of the pull rod 400 fixes the sealing plug 500, and the sealing plug 500 seals and fixes the lower opening of the sampling bucket.

[0022] When the present utility model is in use, first, place the lower opening of the sampling bucket 100 in the molten aluminum through the handle 200, and according to the scale 110 on the outer side of the sampling bucket 100, determine that the depth of the lower end of the sampling bucket 100 from the liquid level of the molten aluminum reaches the required depth. Then, press and rotate the adjusting rod 300 towards the handle 200, driving the elastic component 600 to contract. According to the lever principle, the end of the adjusting rod 300 facing the sampling bucket 100 presses downward, so that the pull rod 400 exerts a downward force on the sealing plug 500 at the end. The sealing plug 500 disengages from the lower opening of the sampling bucket 100, and the lower opening is opened, and the molten aluminum enters the sampling bucket 100 from the lower opening. After sampling is completed, stop pressing the adjusting rod 300, the elastic component 600 recovers, and the end of the adjusting rod 300 facing the sampling bucket 100 moves upward, driving the sealing plug 500 to seal the lower opening through the pull rod 400. Finally, take out the sampling bucket 100 from the molten aluminum, and pour the molten aluminum in the sampling bucket into an ingot for detection. The molten aluminum in the sampling bucket 100 can be poured out from the upper end, or flow out from the lower end by opening the sealing plug at the lower end.

[0023] By setting the handle 200, this device facilitates placing the sampling bucket 100 in the molten aluminum for sampling. And by setting the scale 110, the position of the lower end of the sampling bucket 100 can be known, so that molten aluminum at a specific depth can be sampled during sampling, and the operation is simple and safe. Moreover, the lower end of this device is sealed by a sealing plug 500 to seal the lower opening. When entering the molten aluminum, molten aluminum from other positions will not be sampled. At the same time, after sampling, the lower opening is sealed to avoid sampling molten aluminum from other positions, reducing the influence of molten aluminum at different positions and reducing the error of molten aluminum.

[0024] It further includes a positioning plate 700. The middle of the positioning plate 700 has a circular hole 710, and the diameter of the circular hole 710 is the same as the outer diameter of the sampling bucket 100. The positioning plate 700 can be slidably sleeved outside the sampling bucket 100. A fastening screw hole 720 is provided on the side of the positioning plate 700, and the fastening screw hole 720 is radially arranged, and a bolt is arranged in the fastening screw hole 720. When in use, when it is necessary to sample molten aluminum at a specific depth, for example, sample molten aluminum at a depth of 15 cm, after loosening the bolt, slide the positioning plate to the position where the scale is 15 cm, and then turn the bolt inward so that the inner end of the bolt abuts against the outer wall of the sampling bucket 100, thereby positioning the positioning plate 700 at the scale. When in use, it is only necessary to observe that the positioning plate 700 is flush with the molten aluminum liquid level to achieve positioning to the specified depth, avoiding the situation where the scale is difficult to distinguish or is covered by aluminum slag and cannot be seen, and it is more convenient to position the depth.

[0025] The lower part of the sampling bucket 100 is conical. Through the conical bottom, the resistance of the bottom entering the molten aluminum is reduced, and the force is reduced. A short tube 120 is provided inside the sampling bucket 100. The lower end of the short tube 120 is fixed to the inner wall of the conical part of the sampling bucket 100. The short tube 120 is concentric with the sampling bucket 100, and the inner diameter of the short tube 120 is the same as the diameter of the lower opening of the sampling bucket 100. The length of the short tube 120 is 5 - 8 cm. By setting this short tube 120, when the depth exceeds the length of the short tube 120 during use, the molten aluminum will enter the inside of the sampling bucket 100. Even if the lower bottom is not sealed thoroughly and liquid leakage occurs during use, the molten aluminum inside the sampling bucket 100 below the short tube will not leak out, ensuring that the sample liquid can always be taken and improving the tolerance of the device.

[0026] The sealing plug 500 includes a cover part 510 and a plug part 520. The plug part 520 faces upward. The cover part 510 is concentric with the plug part 520. The upper end of the plug part 520 also has a bullet-shaped top. Through this top, it is ensured that the plug part 520 can more easily enter the opening for sealing, ensuring complete sealing. The pull rod 400 is concentrically connected to the plug part 520. The diameter of the cover part 510 is larger than that of the plug part 520. The diameter of the plug part 520 is equal to the diameter of the lower opening of the sampling bucket 100. When in use, the plug part 520 of the sealing plug enters the short tube for sealing, and the cover part 510 abuts against the end face at the lower end of the sampling bucket, making the sealing more complete and preventing liquid leakage.

[0027] The handle 200 includes a hinge plate 210 and a main handle 220. The hinge plate 210 includes a V-shaped plate 211 and a connecting plate 212. A hinge hole is provided in the middle of the V-shaped plate 211 for installing a pin shaft to hinge and fix the adjusting rod 300, ensuring that the adjusting rod 300 rotates at this position. The V-shaped plate 211 includes a first side and a second side. The included angle between the first side and the second side is 120°. The first side is horizontally arranged. The first side is connected to the main handle 220. The second side is connected to one end of the connecting plate 212. The other end of the connecting plate 212 is fixed to the outer side wall of the upper end of the sampling bucket 100. It is ensured that the handle 200 is firmly installed with the sampling bucket 100. And through the design of the hinge plate 210, it is convenient to hinge the adjusting rod at the hinge plate. And with this V-shaped plate design, space is provided for the rotation at the hinge, facilitating power transmission, pulling the sealing cover for sealing and opening.

[0028] The adjusting rod 300 includes a strip plate 310 and a main rod body 320. One end of the strip plate 310 is connected and fixed to the front end of the main rod body 320. The strip plate 310 is arranged along the length direction of the main rod body 320. Two pin holes 311 are provided on the strip plate 310. A corresponding first pin hole 410 is provided at the top end of the pull rod 400. The pin hole in the middle of the strip plate 310 is used to hinge the V-shaped plate of the handle 200. The pin hole at the top end of the strip plate 310 is connected to the first pin hole through a pin shaft, so that the top of the pull rod 400 and the top of the strip plate 310 are rotatably connected to drive the pull rod to rise or press down, realizing the sealing or opening of the sealing cover.

[0029] The scale 110 ranges from 0 to 20 cm; the starting point 0 cm of the scale 110 is flush with the lower end face of the sampling bucket. Through this scale 110, the depth of the lower end of the sampling bucket can be known, facilitating sampling of the molten aluminum at a specific depth position.

[0030] The elastic component 600 is a spring or a metal spring sheet. Through the deformation and recovery of the elastic component 600, the sealing of the sealing cover is realized.

It must be pointed out that the disclosed embodiments do not limit the scope of the present utility model. On the contrary, modifications and refinements made without departing from the spirit and scope of the present utility model fall within the scope of patent protection of the present utility model.
