Description

Technical Field

[0001] The present invention relates to the technical field of electromagnetic pump aluminum liquid pipeline cleaning, and in particular to a cleaning device for electromagnetic pump aluminum liquid pipelines of a double-chamber melting furnace. Background Art

[0002] The accumulation of slag on the inner wall of the electromagnetic pump pipe will cause the low liquid level of the aluminum water in the charging well of the electromagnetic pump of the double-chamber melting furnace, resulting in problems such as low circulation rate of the aluminum water in the furnace, slow heating, large burning loss, and slow aluminum tapping. Therefore, the double-chamber melting furnace needs to be shut down, and the slag adsorbed on the inner wall of the pump pipe is manually dredged. Manual dredging of the slag is time-consuming, laborious, and affects the progress of production tasks as soon as possible. The cleaning method, aluminum emitter and mold for the electromagnetic pump aluminum liquid pipeline of the double-chamber melting furnace with the patent publication number CN117181730A clean the pipeline slag by putting an aluminum emitter into the charging well. The aluminum emitter is not easy to enter the pipeline in the charging well. At the same time, the aluminum emitter only moves by the thrust of the electromagnetic pump and is easily blocked by the slag and stops moving forward, resulting in limited cleaning effect on the slag.

[0018] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0019] Embodiment 1

[0020] As Figures 1 to 4As shown in the figure, a device for cleaning the aluminum liquid pipeline of an electromagnetic pump in a double-chamber melting furnace provided by the present invention includes an aluminum emitter 1 and a feeding device. The feeding device includes a cover plate 2. The cover plate 2 is provided with a through chute 21. A slider 3 is slidably connected in the chute. The slider 3 is fixedly connected to a suspension pipe 4. An ejector is provided at the lower end of the suspension pipe 4. The aluminum emitter 1 is installed on the ejector. The ejector is used to separate the aluminum emitter 1 from the suspension pipe 4.

[0021] During use, the plugging plate is removed from the installation hole 10 at the upper end of the charging well of the double-chamber melting furnace. After the cover plate 2 of the present invention is adapted to the installation hole 10, it is fixed to the upper end of the charging well by bolts. The cover plate 2 and the suspension pipe 4 align the aluminum emitter 1 with the electromagnetic pump pipe 20 (the suspension pipe 4 is suspended and lowered into the charging well and is coaxial with the electromagnetic pump pipe 20), which facilitates the aluminum emitter 1 to enter the electromagnetic pump pipe 20. The aluminum emitter 1 is coaxially pushed into the electromagnetic pump pipe 20 through the ejector, thereby preventing the aluminum emitter 1 from getting stuck at the inlet of the electromagnetic pump pipe 20, improving the cleaning success rate of the electromagnetic pump pipe 20, and enhancing the cleaning effect.

[0022] The lower end of the suspension pipe 4 is of a closed structure, and the upper end of the suspension pipe 4 is of an open structure. The molten aluminum remaining in the charging well will not enter the interior of the suspension pipe 4 and will not affect the transmission structure inside the suspension pipe 4, facilitating its removal after cleaning.

[0023] As a specific structure of the ejector, the ejector includes a cushion pipe 5. The cushion pipe 5 is fixedly connected to one side of the lower end of the suspension pipe 4. A stepped column 51 is slidably connected in the cushion pipe 5. A limiting plate 52 is sleeved on the stepped side of the stepped column 51. When the stepped column 51 retracts into the suspension pipe 4 relative to the cushion pipe 5, the aluminum emitter 1 is separated. The upper end of the limiting plate 52 extends out of the upper end of the suspension pipe 4 and is fixedly connected to a right-angle rod 53. The right-angle rod 53 is fixedly connected to the cover plate 2. A plurality of card slots 54 are provided at the other end of the stepped column 51. A counterbore 55 is provided at the rear end of the aluminum emitter 1. A plurality of insertion plates 56 are fixedly connected to the inner wall of the counterbore 55 at intervals. The insertion plates 56 are inserted into the card slots 54 in one-to-one correspondence. When the aluminum emitter 1 needs to be separated, the slider 3 slides in the chute. On the one hand, the suspension pipe 4 pushes the aluminum emitter 1 into the electromagnetic pump pipe 20. On the other hand, the limiting plate 52, the right-angle rod 53 and the cover plate 2 are in a fixed state. Therefore, the suspension pipe 4 moves while the stepped column 51 is restricted from moving, and the cushion pipe 5 pushes the aluminum emitter 1 outwards, so that the aluminum emitter 1 can be separated.

[0024] A power storage rotator is provided at one end of the stepped column 51 located inside the suspension pipe 4. After the power storage rotator is released, the stepped column 51 rotates, providing a rotational boost for the aluminum emitter 1 when it enters the electromagnetic pump pipe 20. The rotating aluminum emitter 1 is more likely to strip the slag accumulated on the inner wall of the electromagnetic pump pipe 20.

[0025] The energy storage rotator includes a rotating shaft 6. One end of the rotating shaft 6 is rotatably connected to the suspension pipe 4 and a torsion spring is provided. One end of the stepped column 51 is provided with a sliding hole, and the sliding hole is slidably connected to the rotating shaft 6 and a limiting key shaft 61 is provided. That is, the rotating shaft 6 and the stepped column 51 can move axially relative to each other and can rotate synchronously. The rotating shaft 6 is coaxially and fixedly connected to a sheave 62. A cable 63 is wound around the sheave 62. One end of the cable 63 is fixedly connected to the sheave 62, and the other end of the cable 63 extends out of the upper end of the suspension pipe 4. Pulling the cable 63 outwards causes the sheave 62 to drive the rotating shaft 6 to rotate multiple circles and causes the torsion spring to store energy. When the cable 63 is released, the torsion spring quickly resets, causing the rotating shaft 6 to rotate. The rotating shaft 6 drives the aluminum emitter 1 to rotate through the stepped column 51.

[0026] A tapered column 64 is provided in the middle of the cable 63. A U-shaped limiting groove 65 is provided at the upper end of the limiting plate 52. The diameter of the tapered column 64 is greater than the width of the notch of the U-shaped limiting groove 65. The upper end of the suspension pipe 4 is fixedly connected to an inclined block 66. The inclined block 66 is correspondingly arranged with the tapered column 64. The upper end of the cover plate 2 is fixedly connected to an electric push rod 67. The telescopic end of the electric push rod 67 is fixedly connected to the slider 3.

[0027] In the present invention, pulling the cable 63 outwards causes the sheave 62 to drive the rotating shaft 6 to rotate multiple circles and causes the torsion spring to store energy. The tapered column 64 is stuck on one side of the limiting plate 52. When the suspension pipe 4 sends the aluminum emitter 1 to the nozzle of the electromagnetic pump pipe 20, the electric push rod 67 pushes the slider 3 to slide in the chute. On the one hand, the suspension pipe 4 pushes the aluminum emitter 1 into the electromagnetic pump pipe 20. On the other hand, the limiting plate 52, the right-angle rod 53 and the cover plate 2 are in a fixed state. Therefore, the suspension pipe 4 moves while the stepped column 51 is limited and immovable. The cushion pipe 5 pushes the aluminum emitter 1 outwards, so that the aluminum emitter 1 can be separated. When the aluminum emitter 1 is pushed into the electromagnetic pump pipe 20, the suspension pipe 4 moves to push the tapered column 64 upwards through the inclined block 66. The tapered column 64 leaves the side of the limiting plate 52. The torsion spring quickly resets, causing the rotating shaft 6 to rotate. The rotating shaft 6 drives the aluminum emitter 1 to rotate through the stepped column 51. Rotating the aluminum emitter 1 can more easily scrape the accumulated slag in the electromagnetic pump pipe 20, so the cleaning effect is better.

[0028] Embodiment 2

[0029] As Figures 1 to 4 shown, the aluminum emitter 1 is in the shape of a bullet, which is convenient for moving in the electromagnetic pump pipe 20 in cooperation with the pumping capacity of the electromagnetic pump. Shovels 11 are arranged at intervals around the outer periphery of the bullet head of the aluminum emitter 1. A plurality of spiral grooves 12 are arranged in an annular array on the outer side of the column body of the aluminum emitter 1. The spiral grooves 12 communicate with both end faces of the aluminum emitter 1.

[0030] There is still molten aluminum in the charging well. When the aluminum emitter 1 is blocked by accumulated slag, the molten aluminum flows in the spiral groove 12. Through the pumping suction force of the electromagnetic pump, the molten aluminum passes through the spiral groove 12, causing the aluminum emitter 1 to receive a circumferential thrust from the aluminum liquid. Therefore, it can rotate. On the one hand, it forms an axial thrust and a rotational scraping force on the accumulated slag. The spiral groove 12 can also scrape the accumulated slag. And when the aluminum emitter 1 is blocked, high-speed aluminum liquid (the flow rate increases in the narrow gap) passes through the spiral groove 12, and the aluminum liquid impacts the accumulated slag, making the accumulated slag easier to fall off. On the other hand, the aluminum liquid is easy to wrap the aluminum emitter 1, which is equivalent to forming lubrication between the aluminum emitter 1 and the electromagnetic pump pipe 20, making the aluminum emitter 1 easier to pass through the electromagnetic pump pipe 20. Therefore, the cleaning effect is better.
