Description

Technical Field

[0001] The utility model relates to the technical field of molten aluminum output devices, in particular to a molten aluminum output mechanism with a protective structure for a melting furnace. Background Art

[0002] During the aluminum production process, scrap aluminum is typically melted and recycled in a smelting furnace. Depending on the foundry's needs, it is then exported as molten aluminum or cast into aluminum ingots. The molten aluminum export mechanism directly delivers the melted aluminum directly into an aluminum holding tank.

[0003] The function of the molten aluminum output pipe is to output the molten aluminum into the aluminum insulation tank. However, when the aluminum output pipe is not connected to the insulation tank, it is generally open. In this way, a large amount of dust may enter the interior of the output pipe in the operating room. In this way, when in use, there will be a lot of impurities in the melted aluminum, which will affect the purity of the aluminum. Utility Model Content

[0004] The purpose of the present invention is to provide a molten aluminum output mechanism with a protective structure for a melting furnace, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a molten aluminum output mechanism with a protective structure for a melting furnace, comprising an molten aluminum output pipe, a threaded connection portion fixedly mounted at a through hole of the molten aluminum output pipe, and a protective mechanism provided inside the molten aluminum output pipe, the protective mechanism comprising:

[0006] A moving rod, the outer wall of which penetrates the outer wall of the molten aluminum output pipe and is slidably connected at the penetration point. A compression spring is fixedly installed at the bottom of the molten aluminum output pipe, which can reset the moving rod when the hollow block or the moving rod is not squeezed;

[0007] A hollow block, the top of which is fixedly mounted on the bottom of the extrusion spring, the top of which is fixedly mounted on the top of the moving rod, a compression spring is fixedly mounted in the groove at the bottom of the moving rod, which can reset the L-shaped rod and thus reset the telescopic cylinder.

[0008] Preferably, an L-shaped rod is fixedly installed at one end of the compression spring away from the moving rod, the outer wall of the L-shaped rod is slidably installed in the groove at the bottom of the moving rod, and a telescopic cylinder is fixedly installed on the left side of the L-shaped rod.

[0009] Preferably, a return spring is fixedly installed inside the telescopic cylinder, which can extend the telescopic cylinder when the top of the telescopic cylinder is not squeezed. A U-shaped plate is fixedly installed on the top of the moving rod, and a support plate is fixedly installed on the inner wall of the aluminum water output pipe.

[0010] Preferably, the outer wall of the U-shaped plate is slidably mounted in the groove of the support plate, and a fixing rod is fixedly mounted in the groove of the support plate.

[0011] Preferably, a rotating rod is rotatably mounted on the inner wall of the U-shaped plate, and a torsion spring is fixedly mounted on the inner wall of the U-shaped plate, which can reset the rotating rod and drive the shielding plate to reset when the eccentric column is not squeezed.

[0012] Preferably, one end of the torsion spring away from the U-shaped plate is fixedly mounted on the outer wall of the rotating rod, an eccentric column is fixedly mounted on the front face of the rotating rod, and a blocking plate is fixedly mounted on the outer wall of the rotating rod.

[0013] Compared with the prior art, the present invention provides a molten aluminum output mechanism with a protective structure for a melting furnace, which has the following beneficial effects:

[0014] 1. The molten aluminum output mechanism with a protective structure for a melting furnace is configured such that the bolt on the top of the connecting pipe is screwed into the threaded connection part. When screwing in, the bottom of the hollow block is squeezed, causing the moving rod to move upward. At the same time, the U-shaped plate pushes the rotating rod to drive the shielding disk to move upward, so that the eccentric column is squeezed by the fixed rod to open the shielding disk. Conversely, when the hollow block is not squeezed, the torsion spring resets the rotating rod and the extrusion spring resets the moving rod, so that the shielding disk can block the through hole of the threaded connection part, thereby preventing dust from entering the interior of the molten aluminum output pipe when not in use, thereby affecting the purity of the molten aluminum.

[0015] 2. The molten aluminum output mechanism with a protective structure for the melting furnace will squeeze the bottom of the telescopic cylinder when the bolt of the connecting pipe is screwed into the threaded connection part, causing the telescopic cylinder to move upward, and at the same time the L-shaped rod will move into the groove at the bottom of the moving rod. When the top of the telescopic cylinder is squeezed by the molten aluminum output pipe, the telescopic cylinder will shrink, and when the L-shaped rod cannot move in the groove at the bottom of the molten aluminum output pipe, it will squeeze the moving rod to move upward, thereby opening the shielding disk. Otherwise, the telescopic cylinder will be reset to block the threaded connection part, thereby preventing large particles from sticking to the threads of the threaded connection part, causing the bolt to be unable to be screwed in.

DETAILED DESCRIPTION

[0023] like Figures 1-6 As shown, the utility model provides a technical solution: an aluminum liquid output mechanism with a protective structure for a melting furnace, comprising an aluminum liquid output pipe 1, a threaded connection part 2 is fixedly installed at the through hole of the aluminum liquid output pipe 1, and a protective mechanism 3 is arranged inside the aluminum liquid output pipe 1.

[0024] Specifically, the protection mechanism 3 includes: a moving rod 31, an extrusion spring 32, a hollow block 33, a compression spring 34, an L-shaped rod 35, a telescopic cylinder 36, a return spring 37, a U-shaped plate 38, a support plate 39, a fixed rod 310, a rotating rod 311, a torsion spring 312, an eccentric column 313, and a shielding plate 314. The outer wall of the moving rod 31 passes through the outer wall of the molten aluminum output pipe 1, and the penetration is slidably connected. The bottom of the molten aluminum output pipe 1 is fixedly installed with an extrusion spring 32, the top of the hollow block 33 is fixedly installed at the bottom of the extrusion spring 32, and the top of the hollow block 33 is fixedly installed at the top of the moving rod 31. A compression spring 34 is fixedly installed in the groove at the bottom of the moving rod 31, and the compression spring 34 is away from the moving rod. An L-shaped rod 35 is fixedly installed at one end of the rod 31, and the outer wall of the L-shaped rod 35 is slidably installed in the groove at the bottom of the moving rod 31. A telescopic cylinder 36 is fixedly installed on the left side of the L-shaped rod 35, and a return spring 37 is fixedly installed inside the telescopic cylinder 36. When the bolt of the connecting pipe is screwed into the threaded connection part 2, the bottom of the telescopic cylinder 36 will be squeezed first, causing the telescopic cylinder 36 to move upward. At the same time, the L-shaped rod 35 moves back to the groove at the bottom of the moving rod 31, and the compression spring 34 is compressed. When the top of the telescopic cylinder 36 is squeezed by the molten aluminum output pipe 1, the telescopic cylinder 36 will contract, causing the return spring 37 to compress, and when the L-shaped rod 35 cannot move in the groove at the bottom of the molten aluminum output pipe 1, it will squeeze the moving rod 31 upward. The movable rod 31 is fixed with a U-shaped plate 38 on the top of the movable rod 31. By screwing the bolt at the top of the connecting pipe into the threaded connecting part 2, the bottom of the hollow block 33 is squeezed when screwing in, so that the movable rod 31 moves upward, and the extrusion spring 32 is compressed. When the movable rod 31 moves, it pushes the U-shaped plate 38. The inner wall of the molten aluminum output pipe 1 is fixed with a support plate 39. The outer wall of the U-shaped plate 38 is slidably installed in the groove of the support plate 39. The fixing rod 310 is fixedly installed in the groove of the support plate 39. The inner wall of the U-shaped plate 38 rotates A rotating rod 311 is installed, and a torsion spring 312 is fixedly installed on the inner wall of the U-shaped plate 38. The end of the torsion spring 312 away from the U-shaped plate 38 is fixedly installed on the outer wall of the rotating rod 311. An eccentric column 313 is fixedly installed on the front of the rotating rod 311, and a blocking plate 314 is fixedly installed on the outer wall of the rotating rod 311. The rotating rod 311 drives the blocking plate 314 to move upward. After moving to a certain position, the eccentric column 313 will be squeezed by the fixed rod 310, causing the rotating rod 311 to rotate and the torsion spring 312 to twist. At this time, the rotating rod 311 will drive the blocking plate 314 to open. Conversely, the blocking plate 314 blocks the through hole of the threaded connection part 2 to prevent dust from entering the interior of the molten aluminum output pipe 1 when not in use.

[0025] Working principle: Connect one end of the connecting pipe to the molten aluminum output pipe 1, and the other end to the molten aluminum insulation tank, so that the molten aluminum in the molten aluminum output pipe 1 can be transported to the molten aluminum insulation tank. When the connecting pipe is connected to the molten aluminum output pipe 1, screw the bolt on the top of the connecting pipe into the threaded connection part 2. When screwing in, the bottom of the hollow block 33 will be squeezed, so that the moving rod 31 moves upward, and the squeezing spring 32 is compressed. When the moving rod 31 moves, it pushes the U-shaped plate 38, so that the rotating rod 311 drives the shielding plate 314 to move upward. After moving to a certain position, the eccentric column 313 will be squeezed by the fixed rod 310, causing the rotating rod 311 to rotate and the torsion spring 312 to twist. At this time, the rotating rod 311 will drive the shielding plate 314 to open. On the contrary, when the hollow block 33 is not squeezed, the squeezing spring 32 will reset the moving rod 31. At the same time, the torsion spring 312 will reset the rotating rod 311. In this way, the shielding plate 314 can block the through hole of the threaded connection part 2, preventing dust from entering the interior of the molten aluminum output pipe 1 when not in use, thereby affecting the purity of the molten aluminum.

[0026] When the bolt of the connecting pipe is screwed into the threaded connection part 2, it will first squeeze the bottom of the telescopic cylinder 36, causing the telescopic cylinder 36 to move upward. At the same time, the L-shaped rod 35 will move into the groove at the bottom of the moving rod 31, and the compression spring 34 will be compressed. When the top of the telescopic cylinder 36 is squeezed by the molten aluminum output pipe 1, the telescopic cylinder 36 will shrink, causing the return spring 37 to be compressed. When the L-shaped rod 35 cannot move in the groove at the bottom of the molten aluminum output pipe 1, it will squeeze the moving rod 31 to move upward, thereby opening the shielding plate 314. Conversely, the extrusion spring 32 will reset the moving rod 31, the compression spring 34 will reset the L-shaped rod 35, and the return spring 37 will reset the telescopic cylinder 36. When the telescopic cylinder 36 is reset, it can block the threaded connection part 2, thereby preventing large particles from sticking to the threads of the threaded connection part 2 and causing the bolt to be unable to be screwed in.

[0027] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
