Description

Technical Field

[0001] The present application relates to the field of sampling and detection, and in particular to a molten aluminum sampler. Background Art

[0002] Aluminum is a metal element with the symbol Al. Its single substance is a silvery-white light metal that can be in the form of molten aluminum at high temperatures. Aluminum products are widely used in daily life and industrial production. When producing aluminum products, it is often necessary to sample and test molten aluminum. Molten aluminum sampling is usually carried out in an aluminum smelting furnace or a holding furnace.

[0003] When sampling molten aluminum, a sampler with a fixed capacity is usually used. Such a sampler cannot control the amount of sampling. If the sample is too small, the required amount for the experiment will not be reached and it will need to be collected again. If the sample is too large, it will cause waste. Therefore, the sampling amount cannot be adjusted in time according to needs. Utility Model Content

[0004] In order to facilitate the control of the sampling amount of molten aluminum, the present application provides a molten aluminum sampler.

[0005] The present application provides a molten aluminum sampler, which adopts the following technical solution:

[0006] A molten aluminum sampler comprises a sampling barrel and a quantity control component, wherein a plurality of air holes are provided at the bottom of the sampling barrel, an extension rod is fixedly connected to the outer wall of the sampling barrel, and the quantity control component comprises a quantity control plate, wherein the quantity control plate is arranged parallel to the bottom of the sampling barrel, the quantity control plate is slidably connected to the inner wall of the sampling barrel, a connecting rod is fixedly connected to a side of the quantity control plate away from the bottom of the sampling barrel, a slider is fixedly connected to one end of the connecting rod away from the quantity control plate, a slider is fixedly connected to one end of the extension rod away from the sampling barrel, a slide groove is provided on the side of the slide rod close to the sampling barrel, and the slider is slidably connected to the slide rod through the slide groove.

[0007] By adopting the above technical solution, the slider is controlled to move up and down in the slide slot, driving the quantity control plate to move up and down in the sampling barrel, thereby adjusting the capacity of the space formed by the side wall of the sampling barrel and the quantity control plate, thereby achieving the effect of controlling the sampling amount of molten aluminum. At the same time, a plurality of air holes are provided at the bottom of the sampling barrel, which reduces the possibility of excessive air pressure in the space formed by the quantity control plate and the bottom of the sampling barrel, thereby making it easier to adjust the capacity.

[0008] Optionally, a plurality of threaded holes are formed on a side of the slide groove away from the slider, and bolts are threadedly connected to the threaded holes, and the bolts are used to abut against the slider.

[0009] By adopting the above technical solution, when adjusting the sampling capacity, the current capacity can be more conveniently understood through the position of the bolt, and when the sliding slider stops, the bolt can be rotated until it abuts against the slider to fix the position of the slider, that is, the position of the volume control plate is fixed, thereby reducing the possibility of the volume control plate continuing to slide, thereby improving the reliability of capacity control.

[0010] Optionally, a top cover is fixedly connected to the top of the sampling bucket, a connecting hole is opened at the center of the top cover, the connecting rod is slidably connected to the top cover through the connecting hole, and a water inlet hole is opened on the side of the top of the sampling bucket away from the extension rod.

[0011] By adopting the above technical solution, a top cover is set on the top of the sampling barrel and a water inlet hole is opened, so that the molten aluminum can smoothly enter and exit the sampling barrel while reducing the contact of the molten aluminum with the outside world, thereby slowing down the rate at which the temperature of the molten aluminum decreases and reducing the possibility of the molten aluminum being contaminated.

[0012] Optionally, the sampling bucket is fixedly connected with a pouring spout at the water inlet.

[0013] By adopting the above technical solution and providing a pouring spout, pouring out molten aluminum is made more convenient and the waste in the process of pouring out molten aluminum is reduced.

[0014] Optionally, a sealing ring is fixedly connected to the quantity control plate in the circumferential direction, and the sealing ring is slidably connected to the inner wall of the sampling barrel.

[0015] By adopting the above technical solution and arranging a sealing ring around the quantity control plate, the possibility of molten aluminum flowing out through the gap between the quantity control plate and the inner wall of the sampling barrel is reduced, the waste caused by moving the sampling barrel after sampling is reduced, and the accuracy of the sampling amount is increased.

[0016] Optionally, it also includes a preheating component, which includes a heating resistance wire. A closed annular groove is provided on the side wall of the sampling barrel, and the heating resistance wire is circumferentially wound in the annular groove. A wire groove is provided in the extension rod at one end close to the sampling barrel, and a wire is provided in the wire groove.

A battery groove for installing a battery is provided on the extension rod, and the battery groove is connected with the wire groove. The extension rod is detachably connected to a battery cover at the battery groove.

[0017] By adopting the above technical solution, before sampling molten aluminum, the battery supplies power to the heating resistance wire through the wire, so that the heating resistance wire preheats the sampling barrel, thereby reducing splashing caused by the large temperature difference between the sampling barrel and the molten aluminum, and improving the safety of the sampling process.

[0018] Optionally, a preheating switch is embedded in the extension rod, and the preheating switch is electrically connected to the battery.

[0019] By adopting the above technical solution and setting a preheating switch, there is no need to install batteries before each preheating. It is only necessary to control the preheating time and preheating duration through the preheating switch, so that the preheating process can be controlled more conveniently.

[0020] Optionally, an end of the extension rod away from the sampling barrel is provided with a heat insulating rubber sleeve.

[0021] By adopting the above technical solution, the heat-insulating rubber sleeve can more effectively isolate the heat of the extension rod and at the same time have a certain anti-slip effect, thereby improving the safety of the sampling process.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. By controlling the slider to move up and down in the slide slot, the control plate is driven to move up and down in the sampling barrel, thereby adjusting the capacity of the space formed by the side wall of the sampling barrel and the control plate, so as to achieve the effect of controlling the sampling amount of molten aluminum. At the same time, a plurality of air holes are opened at the bottom of the sampling barrel, which reduces the possibility of excessive air pressure in the space formed by the control plate and the bottom of the sampling barrel, thereby making it easier to adjust the capacity;

[0024] 2. When adjusting the sampling capacity, the bolt position can make it easier to understand the current capacity, and when the sliding slider stops, the bolt can be turned until it abuts against the slider to fix the position of the slider, that is, the position of the volume control plate is fixed, reducing the possibility of the volume control plate continuing to slide, thereby improving the reliability of capacity control.

[0036] The following is combined with Figure 1-4 This application is described in further detail.

[0037] The present application embodiment discloses a molten aluminum sampler. Figure 1-Figure 3 A molten aluminum sampler comprises a sampling barrel 1 for containing molten aluminum and a quantity control component 2 for adjusting the capacity of the sampling barrel 1. A plurality of air holes 11 are provided at the bottom of the sampling barrel 1. An extension rod 3 is fixedly connected to the outer wall of the sampling barrel 1. An end of the extension rod 3 away from the sampling barrel 1 is sleeved with a heat insulating rubber sleeve 34. The quantity control component 2 comprises a quantity control plate 21. The quantity control plate 21 is arranged parallel to the bottom of the sampling barrel 1. The quantity control plate 21 is slidably connected to the inner wall of the sampling barrel 1. A connecting rod 22 is fixedly connected to a side of the quantity control plate 21 away from the bottom of the sampling barrel 1. A slider 23 is fixedly connected to an end of the connecting rod 22 away from the quantity control plate 21. A slider 23 is fixedly connected to an end of the extension rod 3 away from the sampling barrel 1. A slide bar 24 is fixedly connected to a side of the extension rod 3 away from the sampling barrel 1. A slide groove 25 is provided on the side of the slide bar 24 close to the sampling barrel 1. The slider 23 is slidably connected to the slide bar 24 through the slide groove 25.

[0038] The quantity control plate 21 serves as the bottom of the sampling space and forms a sampling space together with the side wall of the sampling barrel 1. The capacity of the sampling space can be adjusted by adjusting the up and down movement of the quantity control plate 21 in the quantity control component 2, and then the sampling amount of the molten aluminum can be adjusted. The air holes 11 at the bottom of the sampling barrel 1 can well adjust the air pressure in the bottom space of the sampling barrel 1, so that the up and down sliding of the quantity control plate 21 is smoother.

[0039] Reference Figure 2-Figure 4 A plurality of threaded holes 26 are provided on one side of the slide groove 25 away from the slider 23 , and bolts are threadedly connected to the threaded holes 26 . The bolts are used to abut against the slider 23 . The slider 23 is T-shaped, and the slide groove 25 is a T-shaped groove.

[0040] When it is necessary to sample molten aluminum, the slider 23 is slid along the slide groove 25 to move the slider 23 up and down, thereby driving the connecting rod 22 to move up and down, and then driving the control plate 21 to move up and down, so as to control the size of the sampling space. When the sampling space is adjusted, the bolt at the position of the rotating slider 23 is abutted against the slider 23, thereby fixing the position of the slider 23, and then fixing the size of the sampling space. The heat-insulating rubber sleeve 34 on the holding extension rod 3 is used to put the sampling barrel 1 into the aluminum smelting furnace or the insulation furnace where the high-temperature aluminum water is located for sampling. The extension rod 3 can effectively reduce the contact between the staff and the high-temperature aluminum water, thereby improving the safety during the sampling process. The T-shaped slider 23 and the slide groove 25 can make the slider 23 slide in the slide groove 25, reducing the possibility that the slider 23 will be separated from the slide groove 25 and the size of the sampling space cannot be adjusted.

[0041] In this embodiment, the threaded holes 26 are not evenly arranged on the sliding rod 24, and the number of the threaded holes 26 is preferably three. The position of one threaded hole 26 corresponds to the capacity of a sampling space. The position of the threaded hole 26 can be made to correspond to the commonly used sampling volume. The three threaded holes 26 have a relatively simple structure while meeting the commonly used sampling volume.

[0042] Reference Figure 2 The control plate 21 is circumferentially fixedly connected with a sealing ring 211, and the sealing ring 211 is slidably connected to the inner wall of the sampling barrel 1. The sealing ring 211 increases the sealing performance of the bottom of the sampling space and reduces the waste of aluminum water during the movement process after sampling.

[0043] A top cover 4 is fixedly connected to the top of the sampling barrel 1, thereby reducing the speed at which the temperature of the aluminum molten metal decreases during the sampling process and reducing the contamination of the aluminum molten metal. A connecting hole 41 is provided at the center of the top cover 4, and the connecting rod 22 is slidably connected to the top cover 4 through the connecting hole 41. A water inlet hole 12 is provided on the side of the top of the sampling barrel 1 away from the extension rod 3, and a pouring spout 5 is fixedly connected to the water inlet hole 12 of the sampling barrel 1.

[0044] During the sampling process, aluminum liquid enters the sampling space through the water inlet 12. Meanwhile, the water inlet 12 is arranged on a side away from the extension rod 3 and is provided with a pouring spout 5 to facilitate pouring of aluminum liquid after sampling.

[0045] Reference Figure 2 and Figure 3, also includes a preheating component 6, the preheating component 6 includes a heating resistance wire 61, a closed annular groove 13 is provided on the side wall of the sampling barrel 1, the heating resistance wire 61 is circumferentially wound in the annular groove 13, and can evenly preheat the sampling barrel 1, a wire groove 31 is provided at one end of the extension rod 3 close to the sampling barrel 1, a wire 62 is arranged in the wire groove 31, the wire groove 31 is connected with the annular groove 13, the wire 62 penetrates into the annular groove 13 and is electrically connected with the heating resistance wire 61, a battery slot 32 for installing a battery 63 is provided on the extension rod 3, the battery slot 32 is connected with the wire slot 31, the extension rod 3 is detachably connected with a battery cover 33 at the battery slot 32, and the battery 63 can be replaced, a preheating switch 64 is embedded in the extension rod 3, the preheating switch 64 is electrically connected with the battery 63, and the preheating time can be controlled by the preheating switch 64.

[0046] Since the temperature of the molten aluminum is high while the temperature of the sampler is low, the temperature difference between the two is large, which can easily cause aluminum liquid to splash during the sampling process. Preheating the sampler by the preheating component 6 before sampling can effectively reduce aluminum liquid splashing and improve the safety during the sampling process. The annular groove 13 does not contact the aluminum liquid inside the sampling barrel 1, reducing the possibility of leakage.

[0047] The implementation principle of the molten aluminum sampler of the embodiment of the present application is as follows: when molten aluminum sampling is required, the slider 23 is moved up and down in the slide groove 25, thereby driving the control plate 21 to move up and down, and the size of the sampling space formed by the control plate 21 and the inner wall of the sampling barrel 1 can be controlled. When the sampling space is adjusted, the bolt at the position of the rotating slider 23 is abutted against the slider 23, thereby fixing the position of the slider 23, and then fixing the size of the sampling space. After the battery 63 is installed, the preheating switch 64 is pressed to start the heating resistor 61. After preheating for a period of time, the heat-insulating rubber sleeve 34 on the extension rod 3 is held and the sampling barrel 1 is placed in the aluminum smelting furnace or the insulation furnace where the high-temperature aluminum water is located for sampling. The aluminum water enters the sampling space through the water inlet 12. After the sampling is completed, the sampling barrel 1 is slowly moved out of the aluminum smelting furnace or the insulation furnace, so that the aluminum water at the bottom of the sampling barrel 1 can flow out through the air vent 11. When the aluminum water is transferred, the aluminum water is poured out through the pouring nozzle 5.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
