Description

Technical Field

[0001] This utility model relates to the field of casting technology, and more specifically, to a ceramic filtration device for molten aluminum. Background Technology

[0002] In the aluminum smelting process, ceramic filtration equipment is a key device for purifying impurities in molten aluminum. Traditional equipment generally adopts an integrated ceramic filter disc structure. For example, the rotor assembly of a bauxite precision ceramic vacuum filter requires the filter plate to be fixed with bolts. When replacing it, the machine must be stopped to disassemble the coupling, vacuum pipeline and fasteners, which takes up to several hours.

[0003] Chinese patent (application number: CN222871826U) discloses a ceramic membrane filtration device with a microporous structure, including a base, a disassembly assembly and a fixing assembly, wherein a first microporous ceramic membrane filter and a second microporous ceramic membrane filter are movably installed on both sides of the upper end of the base, respectively.

[0004] Traditional equipment like the one described above still requires removing bolts to rotate the filter to a horizontal position for filter replacement. Utility Model Content

[0005] Therefore, in order to solve the problem of cumbersome filter replacement in traditional equipment, this utility model provides an aluminum liquid ceramic filtration device, the specific technical solution of which is as follows:

[0006] A ceramic filtration device for molten aluminum, comprising:

[0007] Machine tool;

[0008] A filter tank is disposed on the machine base;

[0009] A drive unit, which is mounted on the machine base;

[0010] A rotating device is mounted on the machine base and rotatably connected to the machine base. The output end of a driving device is connected to the rotating device, and the driving device is used to drive the rotating device to rotate.

[0011] A ceramic filter disc is fitted onto the rotating device. The ceramic filter disc includes multiple filter blocks connected in sequence. One end of each filter block has a first slot, and the other end of each filter block has an insertion part. The insertion part of one filter block is inserted into the first slot of an adjacent filter block, and one filter block is engaged with another adjacent filter block.

[0012] In the aforementioned aluminum molten ceramic filtration equipment, when the filter element needs to be replaced, the filter block to be replaced is rotated upwards, then clamped and pulled out. A new filter block is then inserted into the empty position to complete the replacement. Traditional filter element replacement involves replacing the entire filter block. Since aluminum molten ceramic filtration does not involve the entire filter block remaining immersed in the molten aluminum for continuous filtration, there is a possibility that some parts of the filter block may still meet filtration requirements, leading to waste. This aluminum molten ceramic filtration equipment uses a multi-block design; only the filter block that no longer meets filtration requirements needs to be replaced, avoiding waste. This aluminum molten ceramic filtration equipment solves the problem of cumbersome filter element replacement in traditional equipment.

[0013] Furthermore, the filter tank is provided with an inlet for the aluminum liquid to enter and an outlet for the aluminum liquid to flow out.

[0014] Furthermore, the rotating device includes a rotating shaft, a bearing, and a rotating frame; the bearing is mounted on the machine base, and the rotating shaft is inserted into the inner ring of the bearing; the rotating frame is sleeved on the rotating shaft; the rotating frame is provided with a second slot; and a plurality of filter blocks are inserted into the second slot.

[0015] Furthermore, the first slot is provided with a first slot, and the insertion part is provided with a first engaging part, wherein the first slot of one filter block engages with the first engaging part of the adjacent filter block.

[0016] Furthermore, the outer contour of the first latching portion is triangular; the outer contour of the first slot matches the first latching portion.

[0017] Furthermore, the rotating device includes a swing arm and a first cylinder; the swing arm is mounted on the rotating shaft, one end of the first cylinder is hinged to the swing arm, and the other end of the first cylinder is hinged to the machine base.

[0018] Furthermore, the rotating frame includes a rotating ring and a plurality of connecting blocks; one end of the connecting block is connected to the rotating shaft, and the other end of the connecting block is connected to the rotating ring; the second slot is provided on the rotating ring.

[0019] Furthermore, the outer contour of the filter block is arranged in a fan shape.

[0020] Furthermore, one end of the filter block is inserted into the second slot, and the first slot and the first snap-fit ​​portion are located on the other end of the filter block. Attached Figure Description

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with its embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit its scope of protection.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0034] like Figure 1-6 As shown, an aluminum liquid ceramic filtration device according to one embodiment of the present invention includes a machine base 1, a filter tank 2, a drive device 3, a rotating device 4, and a ceramic filter disc 5; the filter tank 2 is disposed on the machine base 1; the drive device 3 is disposed on the machine base 1; the rotating device 4 is disposed on the machine base 1 and rotatably connected to the machine base 1; the output end of the drive device 3 is connected to the rotating device 4, and the drive device 3 is used to drive the rotating device 4 to rotate; the ceramic filter disc 5 is sleeved on the rotating device 4, and the ceramic filter disc 5 includes a plurality of filter blocks 6 connected in sequence; one end of the filter block 6 is provided with a first slot 7, and the other end of the filter block 6 is provided with an insertion part 8; the insertion part 8 of one filter block 6 is inserted into the first slot 7 of another adjacent filter block 6, and one filter block 6 is engaged with another adjacent filter block 6.

[0035] In the aforementioned aluminum molten ceramic filtration equipment, when the filter element needs to be replaced, the filter block 6 to be replaced is rotated upwards, then clamped and pulled out. A new filter block 6 is then inserted into the empty position to complete the replacement. Traditional filter element replacement involves replacing the entire filter block. Since aluminum molten ceramic filtration does not involve the entire filter block remaining in the molten aluminum for continuous filtration, there is a possibility that some parts of the filter block may still meet filtration requirements, leading to waste. This aluminum molten ceramic filtration equipment uses a design with multiple filter blocks 6; only the filter block 6 that no longer meets filtration requirements needs to be replaced, avoiding waste. This aluminum molten ceramic filtration equipment solves the problem of cumbersome filter element replacement in traditional equipment.

[0036] like Figure 1-2 As shown, in one embodiment, the filter tank 2 is provided with an inlet for molten aluminum to enter and an outlet for molten aluminum to flow out; the rotating device 4 includes a rotating shaft 41, a bearing 42, and a rotating frame 43; the bearing 42 is mounted on the machine base 1, and the rotating shaft 41 is inserted into the inner ring of the bearing 42; the rotating frame 43 is sleeved on the rotating shaft 41; the rotating frame 43 is provided with a second slot 11; and multiple filter blocks 6 are inserted into the second slot 11. Thus, by providing the second slot 11, the filter blocks 6 are prevented from becoming loose.

[0037] like Figure 1-6 As shown, in one embodiment, the first slot 7 is provided with a first slot 9, and the insertion part 8 is provided with a first engaging part 10. The first slot 9 of one filter block 6 engages with the first engaging part 10 of an adjacent filter block 6. The outer contour of the first engaging part 10 is triangular. The outer contour of the first slot 9 matches the first engaging part 10. In this way, the filter block 6 is inserted into the second slot 11 by engaging with the first slot 9 through the first engaging part 10, thus preventing the filter block 6 from falling out.

[0038] like Figure 1-6 As shown, in one embodiment, the rotating device 4 includes a swing arm 31 and a first cylinder 32; the swing arm 31 is mounted on the rotating shaft 41, one end of the first cylinder 32 is hinged to the swing arm 31, and the other end of the first cylinder 32 is hinged to the machine base 1. Thus, the reciprocating rotation of the ceramic filter disc 5 is achieved through the extension and retraction movement of the first cylinder 32.

[0039] like Figure 1-6 As shown, in one embodiment, the rotating frame 43 includes a rotating ring 431 and a plurality of connecting blocks 432; one end of the connecting block 432 is connected to the rotating shaft 41, and the other end of the connecting block 432 is connected to the rotating ring 431; the second slot 11 is disposed on the rotating ring 431; the outer contour of the filter block 6 is fan-shaped; one end of the filter block 6 is inserted into the second slot 11, and the first slot 9 and the first engaging part 10 are disposed on the other end of the filter block 6. Thus, by placing the first slot 9 and the first engaging part 10 on the outermost ring of the filter section, adjacent filter blocks 6 are prevented from separating.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
