Description

Technical Field

[0001] This utility model relates to the field of melting tank technology, specifically a recycled aluminum melting tank. Background Technology

[0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by remelting and refining scrap aluminum and scrap aluminum alloy materials or aluminum-containing waste. It is an important source of metallic aluminum. After the recycled aluminum is smelted, the aluminum liquid is usually transported by a melting tank. The aluminum liquid is guided to the next processing step by flowing in the melting tank.

[0003] When using the existing recycled aluminum melting tank, since there may be certain impurity particles in the aluminum-containing waste, a filter structure is sometimes set in the melting tank after the waste is melted to filter the aluminum liquid. However, during the filtration process, the filter structure usually traps particulate impurities in the melting tank. After the flow is finished, a certain amount of aluminum liquid may remain. After the aluminum liquid solidifies, it is quite troublesome to clean the particulate impurities left in the solidified aluminum liquid, making the cleaning of particulate impurities in the melting tank take a relatively long time. Thus, during the cleaning process, the flow of aluminum liquid needs to be stopped, and the long cleaning time can easily affect the subsequent production of aluminum liquid. Utility Model Content

[0004] The purpose of this invention is to provide a recycled aluminum melting tank to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A recycled aluminum melting tank includes a tank body 1, a tank body 2 at the top of the tank body 1, and an opening slot in the tank body 2. A filter box is disposed inside the tank body 1 corresponding to the opening slot. Three filter frames 1 are slidably connected to the filter box, and filter frames 2 are slidably connected to the bottom of the filter box. Filter screens are fixedly connected inside both filter frames 1 and 2. The three filter frames 1 are respectively disposed inside the two long sides of the filter box and the side away from the tank body 2. The filter frames 2 are slidably inserted into the bottom of the filter box. The filter box is tightly attached to the inner wall of the tank body 1 near the end of the tank body 2. The bottom surface of the filter box is higher than the inner bottom surface of the tank body 1. The width of the filter box is less than the width of the tank body 1. The tank body 2 includes a flow-inducing section and a conveying section. The width of the conveying section is less than the width of the flow-inducing section. The opening slot is disposed at the bottom of the conveying section. The width of the conveying section is the same as the width of the filter box.

[0007] Furthermore, the filter box is slidably connected with three plug-in blocks that are slidably inserted into an adjacent filter frame, and the bottom end of the plug-in block is slidably inserted into the top surface of an adjacent filter frame.

[0008] Furthermore, the first trough is fixedly connected to a support frame, and the second trough is fixedly connected to two plug-in plates that are slidably inserted into the support frame. The support frame is located at the end of the first trough, the bottom surface of the second trough is in contact with the top surface of the support frame, the plug-in plates are fixedly located on the bottom surface of the second trough, and the plug-in plates are slidably inserted into the top of the support frame.

[0009] Furthermore, the filter box has several strip-shaped grooves located on the sides of the two long sides of the filter box, and the strip-shaped grooves are located on the top of the filter frame.

[0010] Furthermore, the top surface of the inner surface of the strip groove is at the same height as the top surface of the groove body.

[0011] Preferably, the first tank is fixedly connected to a baffle frame that contacts the bottom surface of the second tank, and the filter box is fixedly connected to a hanger that is slidably connected to the baffle frame.

[0012] Furthermore, the top surface of the baffle frame has two limiting grooves, and the limiting grooves are slidably connected to limiting blocks that contact the hanger. The limiting grooves are located on the side of the hanger away from the second groove, and the bottom of the limiting block is provided with an inclined surface corresponding to the hanger.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. A filter box is installed inside the first tank. The molten aluminum from the outlet of the smelting furnace inside the second tank can fall into the second tank and flow along the inside of the second tank. The molten aluminum can pass through the opening slot and fall into the filter box. The molten aluminum is filtered by the filter screens on the first and second filter frames. Particulate impurities will remain inside the filter box, thus minimizing the accumulation of particulate impurities on the inner wall of the first tank. When a lot of impurities accumulate inside the filter box, the filter box can be removed from the first tank and replaced with a new filter box. When cleaning particulate impurities inside the old filter box, the molten aluminum can continue to be filtered through the new filter box. This helps to reduce the impact of cleaning particulate impurities on the flow of molten aluminum during processing.

[0015] 2. By setting a second filter frame at the bottom of the filter box and a first filter frame on the side of the filter box, most particulate impurities will remain on the filter screens of the first and second filter frames when the aluminum liquid is filtered. There will be relatively few particulate impurities on the inner wall of the filter box, and the time spent cleaning the inner wall of the filter box will be relatively short. Filter frames one and two can be removed and replaced, which facilitates cleaning of the inside of the filter box. At the same time, the filter box is relatively long, and with the second filter frame and three first filter frames, the filtration area of ​​the aluminum liquid is large, which helps to reduce the frequency of replacing the first and second filter frames and facilitates continuous filtration of the aluminum liquid.

[0022] 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.

[0023] Please see Figure 1-5 In this embodiment of the present invention, a recycled aluminum melting tank includes a tank body 10, a tank body 20 is provided at the top of the tank body 10, the tank body 20 has an opening slot 22, a filter box 30 is provided inside the tank body 10 corresponding to the opening slot 22, the bottom surface of the tank body 20 can abut against the top surface of the filter box 30, the tank body 20 includes a diversion section and a conveying section, the width of the conveying section is smaller than the width of the diversion section, the opening slot 22 is provided at the bottom of the conveying section, the width of the conveying section is the same as the width of the filter box 30, the filter box 30 is closely attached to the inner wall of the end of the tank body 10 near the tank body 20, the height of the bottom surface of the filter box 30 is higher than the inner bottom surface of the tank body 10, the length of the filter box 30 is greater than the length of the opening slot 22, and the width of the filter box 30 is smaller than the width of the tank body 10.

[0024] The filter box 30 is slidably connected to three filter frames 32. The bottom of the filter box 30 is slidably connected to a filter frame 33. Filter screens 34 are fixedly connected inside both filter frames 32 and filter frames 33. The filter screens 34 can be aluminum water filter screens 34, or ceramic foam filter plates, glass fiber felt, etc. The three filter frames 32 are respectively set inside the two long sides of the filter box 30 and inside the side away from the tank body 20. The filter frames 33 are slidably inserted into the bottom of the filter box 30. The tank body 10 is fixedly connected to a support frame 11. The tank body 20 is fixedly connected to two plug-in plates 21 that are slidably inserted into the support frame 11. The support frame 11 is set at the end of the tank body 10. The bottom surface of the tank body 20 contacts the top surface of the support frame 11. The plug-in plates 21 are fixedly set on the bottom surface of the tank body 20 and are slidably inserted into the top of the support frame 11.

[0025] Specifically, after the plug-in plate 21 is inserted into the support frame 11, the support frame 11 can restrict the horizontal movement of the second tank 20 through the plug-in plate 21. The support frame 11 can support the second tank 20 and can connect the inside of the second tank 20 to the outlet of the smelting furnace. After the aluminum liquid falls into the guide section of the second tank 20, it will flow along the inside of the guide section to the conveying section. The aluminum liquid can pass through the opening slot 22 of the conveying section and fall into the filter box 30. The aluminum liquid is filtered by the filter screen 34 on the filter frame 32 and the filter frame 33. The filter box 30 is relatively long, and the filter box 30 is equipped with the filter frame 33 and three filter frames 32. This provides a large filtration area for the aluminum liquid, which helps to reduce the frequency of replacing the filter frame 32 and the filter frame 33 and facilitates continuous filtration of the aluminum liquid.

[0026] During filtration, particulate impurities will remain inside the filter box 30, thus minimizing their accumulation on the inner wall of the tank 10. When a large amount of impurities accumulate inside the filter box 30, the filter box 30 can be moved away from the tank 20 and then removed from the tank 10 to replace it with a new filter box 30. When cleaning particulate impurities from the old filter box 30, the aluminum liquid can continue to be filtered through the new filter box 30, which helps to reduce the impact of cleaning particulate impurities on the flow of aluminum liquid during processing.

[0027] When the filter screen 34 filters the molten aluminum, most of the particulate impurities will remain on the filter screen 34 of filter frame 1 32 and filter frame 2 33. There are relatively few particulate impurities on the inner wall of the filter box 30. After the filter box 30 is removed, filter frame 1 32 and filter frame 2 33 can be knocked out from inside the filter box 30. Then, the filter box 30 can be inverted using clamping tools, and the unsolidified residual molten aluminum and particulate impurities can be scraped off with a scraper. Cleaning the inside of the filter box 30 is relatively simple and takes relatively little time. The filter box 30 is relatively small in size, making it easy to adjust the angle of the filter box 30 according to cleaning needs, which facilitates cleaning the inside of the filter box 30.

[0028] Example 1

[0029] like Figure 1-3 As shown, in this embodiment, a baffle frame 40 is fixedly connected to the bottom surface of the tank body 20, and a filter box 30 is fixedly connected to a hanger 31 that is slidably connected to the baffle frame 40. The hanger 31 can be hung on the baffle frame 40. The baffle frame 40 supports the filter box 30 through the hanger 31, so that the side wall of the filter box 30 has a certain distance from the inner wall of the tank body 10, so that the aluminum liquid can pass through the filter screen 34 and enter the interior of the tank body 10. The baffle frame 40 can support the conveying section of the tank body 20. Two limiting grooves 41 are opened on the top surface of the baffle frame 40. The limiting grooves 41 are slidably connected to the limiting blocks 50 that are in contact with the hanger 31. The limiting grooves 41 are located on the side of the hanger 31 away from the tank body 20. The bottom of the limiting block 50 is provided with an inclined surface corresponding to the hanger 31.

[0030] In practice, the limiting block 50 can abut against the side wall of the hanger 31, preventing the hanger 31 from moving away from the tank 20. This causes the filter box 30 to abut against the inner wall of the baffle frame 40 near the tank 20, thus restricting the horizontal movement of the filter box 30. When it is necessary to remove the filter box 30, the limiting block 50 can be pulled out, and then the hanger 31 and the filter box 30 can be moved away from the tank 20, causing the filter box 30 to be misaligned with the bottom of the tank 20. At this time, the filter box can be removed using clamping tools, etc. Remove the filter box 30 from inside the tank 10, so that the hanger 31 is separated from the baffle 40. Then the inside of the filter box 30 can be cleaned. A new filter box 30 can be placed inside the baffle 40, so that the hanger 31 is hung on the top of the baffle 40. Then the filter box 30 can be moved to the bottom of the tank 20. Then the limiting block 50 is inserted into the limiting groove 41. The bottom of the limiting block 50 can be angled to the side wall of the hanger 31 to facilitate the insertion of the limiting block 50 into the limiting groove 41 and to hold the hanger 31 in place.

[0031] like Figure 4 and Figure 5 As shown, in this embodiment, the filter box 30 is slidably connected to three plug-in blocks 36 that are slidably plugged into the adjacent filter frame 32, and the bottom end of the plug-in block 36 is slidably plugged into the top surface of the adjacent filter frame 32.

[0032] In practice, the plug-in block 36 can be inserted into the filter box 30 and into the top of the corresponding filter frame 32, thereby restricting the position of the filter frame 32 and keeping it relatively stably inside the filter box 30. After the filter box 30 is removed from the groove 10, the plug-in block 36 can be pulled out. At this time, the filter frame 32 can be knocked out from inside the filter box 30, and the filter box 30 can be inverted to knock out the filter frame 33, making it easy to replace the filter frame 32 and the filter frame 33.

[0033] Example 2

[0034] Based on Example 1, such as Figure 4 As shown, in this embodiment, the filter box 30 has several strip grooves 35. The strip grooves 35 are located on the sides of the two long sides of the filter box 30. The strip grooves 35 are located on the top of the filter frame 32. The inner top surface of the strip grooves 35 is at the same height as the top surface of the groove body 10.

[0035] In practice, the baffle frame 40 can block the top of the filter box 30 and the strip groove 35. If the filter screen 34 on the filter box 30 is blocked, or if the amount of aluminum liquid falling into the filter box 30 suddenly increases due to an accident, causing the aluminum liquid level in the filter box 30 to rise, the aluminum liquid can flow out of the filter box 30 from the strip groove 35 after the aluminum liquid level rises to the position of the strip groove 35, which can minimize the possibility of aluminum liquid falling out of the tank body 10.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
