This invention relates to the field of crucible degassing technology, and provides a placement rack. A clearance hole is provided in the center of the base plate, and the axis of the clearance hole is parallel to the axis of the graphite rotor. Two sets of support plates are provided, symmetrically arranged along a first horizontal direction. Each support plate set includes two support plates, symmetrically arranged along a second horizontal direction. The first support platform of each support plate is located above the second support platform, and each support plate corresponds to a leg.

Description

Technical Field

[0001] This invention relates to the field of crucible degassing technology, and more particularly to a placement rack. Background Technology

[0002] In aluminum casting, degassing requires preheating the graphite rotor of the degassing unit. When multiple degassing units need preheating, poor timing coordination can occur. Before degassing, the graphite rotor needs to be baked for a period of time. During this process, a crane lifts one degassing unit to a specific baking furnace for preheating for about half an hour. After preheating, the degassing unit is then lifted into the molten aluminum in the furnace for degassing. Then, the next mobile degassing unit is lifted and preheated again before being lowered into the molten aluminum. If degassing is required for three or more crucibles, the delayed baking process of the graphite rotor can lead to discontinuity in the degassing process. This could result in the first crucible finishing degassing while the last is just beginning. The larger the time interval, the less effective the initial degassing becomes, and this can also cause coordination problems in other operations.

[0003] Therefore, there is an urgent need for a storage rack to solve the above-mentioned technical problems. Summary of the Invention

[0004] The purpose of this invention is to provide a placement rack that can break the one-to-one binding relationship between the trolley and the degassing device, so that the trolley can be fully utilized, thereby shortening the interval time between degassing operations between multiple crucibles.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A support frame for supporting a degassing device, the degassing device comprising a body, support legs, and a graphite rotor, the graphite rotor being rotatably connected to the body with its rotation axis perpendicular to the horizontal direction, and four support legs evenly distributed around the axis of the graphite rotor and fixed to the body; the support frame comprising:

[0007] The base plate has a clearance hole in the middle, and the axis of the clearance hole is parallel to the axis of the graphite rotor.

[0008] The support plate assembly includes two sets of support plates, which are symmetrically arranged along a first horizontal direction. Each support plate assembly includes two support plates, which are symmetrically arranged along a second horizontal direction. Each support plate includes a first support platform and a second support platform, and is arranged vertically. The first support platform is located above the second support platform, and each support plate corresponds to a leg.

[0009] When the degassing device is in the first position, the support leg abuts against the first support platform in the vertical direction via the support beam, and the graphite rotor is located above the base plate; when the degassing device is in the second position, the support leg abuts against the second support platform in the vertical direction, and the graphite rotor passes through the base plate in the vertical direction.

[0010] As a preferred technical solution of the above-mentioned placement rack, the two support plates in each group of support plates are provided with first positioning holes along the second horizontal direction, the support legs are provided with second positioning holes, and the support beam passes through the first positioning holes and the second positioning holes along the second horizontal direction.

[0011] As a preferred technical solution for the aforementioned placement rack, both the first positioning hole and the second positioning hole are square holes, and the support beam is a corresponding square tube.

[0012] As a preferred embodiment of the aforementioned placement rack, a connecting rod is connected between the two sets of support plates, and the axis of the connecting rod is parallel to the first horizontal direction.

[0013] As a preferred technical solution of the above-mentioned placement rack, the support leg is a square tube, and a limiting abutment surface is provided between the first support platform and the second support platform. The limiting abutment surface is perpendicular to the second horizontal direction and abuts against the support leg in the second horizontal direction.

[0014] As a preferred technical solution of the aforementioned placement rack, the second support platform is provided with a insertion hole along the vertical direction, and the support leg can be inserted into the insertion hole along the vertical direction.

[0015] As a preferred technical solution for the aforementioned placement rack, the aforementioned support plate and the aforementioned base plate are detachably connected.

[0016] As a preferred embodiment of the aforementioned placement rack, the support plate is provided with a stop bar on the side facing away from the clearance hole in the first horizontal direction, and the stop bar can abut against the aforementioned degassing device in the first horizontal direction.

[0017] As a preferred embodiment of the aforementioned placement rack, in the aforementioned vertical direction, the aforementioned stop bar is located above the aforementioned second support platform.

[0018] As a preferred technical solution for the aforementioned placement rack, an anti-slip layer is provided on the side of the base plate facing away from the support plate.

[0019] Beneficial effects of this invention:

[0020] This application provides a mounting frame for supporting a degassing device. The degassing device includes a body, support legs, and a graphite rotor. The graphite rotor is rotatably connected to the body, and the axis of rotation is perpendicular to the horizontal direction. Four support legs are provided, which are evenly distributed around the axis of the graphite rotor and are all fixed to the body. The mounting frame includes a base plate, a support plate assembly, and a support beam. The base plate has a clearance hole in the middle, and the axis of the clearance hole is parallel to the axis of the graphite rotor. Two sets of support plates are provided, symmetrically arranged along a first horizontal direction. Each support plate set includes two support plates, which are symmetrically arranged along a second horizontal direction. Each support plate includes a first support platform and a second support platform, and the first support platform is located above the second support platform in the vertical direction. Each support plate corresponds to a support leg. When the degassing device is in the first position, the support leg abuts against the first support platform in the vertical direction via a support beam, and the graphite rotor is located above the base plate. When the degassing device is in the second position, the support leg abuts against the second support platform in the vertical direction, and the graphite rotor passes through the base plate in the vertical direction.

[0021] In this way, the preheating and degassing processes of the degassing device are supported and fixed by the placement frame, eliminating the need for the crane to hoist the device throughout the process. Therefore, when multiple crucibles need to be degassed simultaneously, a placement frame is clamped on each crucible, and the crane can transport the degassing device onto the placement frame. This removes the one-to-one binding relationship between the crane and the degassing device, allowing the crane to be fully utilized and thus shortening the interval between degassing operations between multiple crucibles.

[0040] like Figures 1 to 4 As shown, this application provides a placement rack 200 for supporting a degassing device 100. The degassing device 100 includes a body 110, support legs 120 and a graphite rotor 130. The graphite rotor 130 is rotatably connected to the body 110 and the rotation axis is perpendicular to the horizontal direction. Four support legs 120 are provided. The four support legs 120 are evenly distributed around the axis of the graphite rotor 130 and are all fixed to the body 110. The placement rack 200 includes a base plate 210, a support plate assembly 220 and a support beam 230. The base plate 210 has a clearance hole 211 in the middle, and the axis of the clearance hole 211 is parallel to the axis of the graphite rotor 130. Two sets of support plate assemblies 220 are provided, symmetrically arranged along the first horizontal direction X. Each support plate assembly 220 includes two support plates 221, symmetrically arranged along the second horizontal direction Y. Each support plate 221 includes a first support platform 2211 and a second support platform 2212, and is aligned with the vertical direction Z. 11 is located above the second support platform 2212, and the support plate 221 corresponds one-to-one with the support leg 120; when the degassing device 100 is in the first position, the support leg 120 abuts against the first support platform 2211 in the vertical direction Z through the support beam 230, and the graphite rotor 130 is located above the base plate 210; when the degassing device 100 is in the second position, the support leg 120 abuts against the second support platform 2212 in the vertical direction Z, and the graphite rotor 130 passes through the base plate 210 in the vertical direction Z.

[0041] Specifically, the placement rack 200 is mounted on the open end face of the crucible 300, which contains molten aluminum. The base plate 210 of the placement rack 200 abuts against the open end face of the crucible 300 in the vertical direction Z. The clearance hole 211 of the base plate 210 is directly opposite the opening of the crucible 300. Before the degassing device 100 degasses the crucible 300, the graphite rotor 130 of the degassing device 100 needs to be preheated. The degassing device 100 is transported to the placement rack 200 by a crane. The degassing device 100 is preheated in the first position. At this time, the support leg 120 abuts against the first support platform 2211 in the vertical direction Z through the support beam 230 to maintain the degassing device 100 and the placement rack 200. Stable, the graphite rotor 130 is located on the side of the base plate 210 facing away from the crucible 300. The heat from the crucible 300 preheats the graphite rotor 130 through the clearance hole 211. After preheating, the support beam 230 is released from contact with the first support platform 2211, allowing the degassing device 100 to move vertically in the Z direction to the second position. The lower end face of the support leg 120 abuts against the second support platform 2212 vertically in the Z direction to maintain the stability of the degassing device 100 and the placement frame 200. At this time, the graphite rotor 130 extends into the crucible 300 through the clearance hole 211 and is submerged in the aluminum solution. During the degassing operation, the graphite rotor 130 can rotate relative to the machine body 110 to agitate the aluminum solution and perform degassing.

[0042] Thus, the preheating and degassing processes of the degassing device 100 are both supported and fixed by the placement rack 200, eliminating the need for a crane to hoist the device throughout the process. Therefore, when multiple crucibles 300 need to be degassed simultaneously, a placement rack 200 is clamped on each crucible 300, and the crane can transport the degassing device 100 to the placement rack 200. This removes the one-to-one binding relationship between the crane and the degassing device 100, allowing the crane to be fully utilized and shortening the interval between degassing operations of multiple crucibles 300.

[0043] Furthermore, when the degassing device 100 has completed preheating and needs to be switched from the first position to the second position, the support beam 230 needs to be removed. Therefore, a crane is generally required to hoist the degassing device 100 to maintain its stability.

[0044] It should be noted that the specific structure and working method of the degassing device 100 are existing technologies and will not be described in detail here.

[0045] Specifically, the preheating time for the graphite rotor 130 is approximately 30 minutes.

[0046] Specifically, each set of support plates 221 in each set of support plates 220 has a first positioning hole 2213 along the second horizontal direction Y, and the support leg 120 has a corresponding second positioning hole. The support beam 230 passes through the first positioning hole 2213 and the second positioning hole along the second horizontal direction Y.

[0047] Furthermore, to prevent relative rotation between the support leg 120 of the degassing device 100 and the support beam 230, or between the support plate 221 and the support beam 230, which could cause relative rotation and offset between the degassing device 100 and the placement frame 200, in this embodiment, both the first positioning hole 2213 and the second positioning hole are square holes, and the support beam 230 is a corresponding square tube. Thus, the insertion of the square hole and the square tube forms a circumferential limit, restricting relative rotation.

[0048] Optionally, a connecting rod 222 connects the two sets of support plate assemblies 220, with the axis of the connecting rod 222 parallel to the first horizontal direction X. This allows the two sets of support plate assemblies 220 to support each other in the first horizontal direction X, enhancing structural strength.

[0049] Optionally, the support leg 120 is a square tube, and a limiting abutment surface 2214 is provided between the first support platform 2211 and the second support platform 2212. The limiting abutment surface 2214 is perpendicular to the second horizontal direction Y and abuts against the support leg 120 in the second horizontal direction Y. Thus, when the degassing device 100 moves from the first position to the second position, the support plate assembly 220 is provided with two limiting abutment surfaces 2214 in the second horizontal direction Y to form a sliding groove. The support leg 120 of the degassing device 100 slides relative to the placement frame 200 along the limiting abutment surface 2214 in the sliding groove, making the sliding more stable.

[0050] Optionally, the second support platform 2212 has a insertion hole along the vertical direction Z, and the support leg 120 can be inserted into the insertion hole along the vertical direction Z. With this configuration, the insertion of the support leg 120 of the degassing device 100 into the insertion hole restricts the relative movement of the degassing device 100 and the placement frame 200 in the horizontal direction, and due to gravity, the degassing device 100 is also not easily removed from the insertion hole.

[0051] Optionally, the support plate 221 and the base plate 210 can be detachably connected. In this way, the placement rack 200 can adaptively adjust the spacing between the support plates 221 according to the size of the degassing device 100.

[0052] Optionally, the support plate 221 is provided with a stop bar on the side opposite to the clearance hole 211 in the first horizontal direction X. The stop bar can abut against the degassing device 100 in the first horizontal direction X. With this arrangement, the stop bar can prevent relative movement of the degassing device 100 relative to the placement frame 200 in the first horizontal direction X.

[0053] Optionally, in the vertical Z direction, the stop lever is located above the second support platform 2212. With this configuration, the stop lever is adjacent to the machine body 110, the bottom end face of the support leg 120 abuts against the second support platform 2212, and a baffle at the other end limits the upper end of the support leg 120 or the machine body 110, thereby limiting the sway amplitude of the entire degassing device 100 when the graphite rotor 130 rotates for degassing.

[0054] Optionally, an anti-slip layer is provided on the side of the base plate 210 facing away from the support plate 221. This design increases the friction between the base plate 210 and the end face of the crucible 300, allowing the placement rack 200 to be placed more stably on the upper end face of the crucible 300.

[0055] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
