[0002] A smelting furnace refers to a device that melts metal ingots and some scrap metals and adds necessary alloy components, and then smelts them into the required alloy through operations such as slag removal and refining. Slag removal is an important process in smelting. When the charge is fully melted in the smelting furnace and the melt temperature reaches the smelting temperature, the slag removal operation can be carried out to remove a large amount of slag on the surface of the melt. However, manual slag removal is time-consuming and labor-intensive, the slag removal efficiency is low, and due to the high temperature near the furnace, manual slag removal has the risk of being scalded. The existing slag removal device generally fishes out once and dumps once, which is cumbersome to operate, and directly transferring and dumping after fishing will result in incomplete filtration and waste of molten liquid.

The waste collection box 2 and the lifting mechanism 3 are both arranged on the support frame 1. The push-pull mechanism 4 is arranged at the output end of the lifting mechanism 3 and is slidably arranged on the support frame 1. The slag scoop box 5 is slidably arranged at the output end of the push-pull mechanism 4. The limit mechanism 6 is arranged between the push-pull mechanism 4 and the slag scoop box 5. The lifting mechanism 3 is arranged to control the up and down movement of the push-pull mechanism 4, thereby controlling the up and down movement of the slag scoop box 5; the push-pull mechanism 4 is arranged to control the horizontal movement of the slag scoop box 5, thereby controlling the slag scoop box 5 to transport the waste slag to the top of the waste collection box 2; the limit mechanism 6 is arranged to control the opening and closing of the bottom of the slag scoop box 5, thereby facilitating the unloading of the waste slag in the slag scoop box 5 into the waste collection box 2; and the waste collection box 2 is arranged to allow the waste slag to be scooped several times and then transferred, thereby improving the slag removal efficiency.

[0024] Specifically, the support frame 1 includes a base 11, a vertical plate 12 arranged at the top of the base 11 and a horizontal plate 13 arranged at one side of the vertical plate 12, a rectangular groove 14 is arranged above the vertical plate 12, and a limiting column 15 is arranged in the vertical direction in the rectangular groove 14, and there are two limiting columns 15.

[0025] In order to be able to transfer the waste slag together after multiple scooping, the waste collecting box 2 is arranged on the side of the horizontal plate 13 away from the vertical plate 12; in order to better filter the residual liquid in the waste slag, a filter hole is arranged at the bottom of the waste collecting box 2, and there are multiple filter holes.

[0026] The lifting mechanism 3 includes a lifting cylinder 31 and a lifting plate 32. In order to better support the lifting mechanism 3 and maintain the stability of the entire device, a support platform 16 is provided on the side of the vertical plate 12 away from the horizontal plate 13, the lifting cylinder 31 is provided on the top of the support platform 16, and the lifting plate 32 is provided at the output end of the lifting cylinder 31. In order to make the lifting of the lifting plate 32 more stable, the lifting plate 32 is slidably provided on the limiting column 15.

[0027] In order to control the horizontal movement of the slag box 5, the push-pull mechanism 4 is arranged at the top of the lifting plate 32, and the push-pull mechanism 4 includes a push-pull cylinder 41, a push rod 42 and a transmission rod 43. The push rod 42 is arranged at the output end of the push-pull cylinder 41, and the push rod 42 passes through the transmission rod 43 arranged on the side of the slag box 5 away from the vertical plate 12.

[0028] In order to facilitate the scooping of waste slag in the furnace, the scooping box 5 is a box body with an upper end opening, and a filter plate 51 is slidably arranged at the bottom of the scooping box 5, and a plurality of filter holes are arranged on the filter plate 51. In order to facilitate the control of the opening and closing of the filter plate 51, the side of the filter plate 51 away from the vertical plate 12 is connected to the lower part of the transmission rod 43.

[0029] When the push-pull cylinder 41 drives the push rod 42 to move, the push rod 42 drives the filter plate 51 to be pulled out from the bottom of the slag box 5 through the transmission rod 43. After the bottom of the slag box 5 is opened, the lifting mechanism 3 controls the slag box 5 to move downward into the molten metal of the furnace to cover the waste slag. At this time, the push-pull mechanism 4 controls the filter plate 51 to close the bottom of the slag box 5 to collect the waste slag. Then the lifting mechanism 3 controls the slag box 5 to move upward to above the molten metal to filter the waste slag. The push-pull mechanism 4 then pulls the slag box 5 back to above the waste collecting box 2.

[0030] In order to better control the movement of the slag box 5 and the filter plate 51 together, a limiting mechanism 6 is arranged at the top of the lifting plate 32, and the limiting mechanism 6 includes a limiting rod 601, an installation box 602, a first sliding groove 603, a first rack 604, a gear 605, a second sliding groove 606, a second rack 607, a spring 608, a limiting groove 609, a through groove 610 and a driving device 7. The limiting groove 609 is arranged on the pushing rod 42, and the through groove 610 is arranged on the limiting rod 601. The limiting rod 601 is sleeved on the outer surface of the pushing rod 42, the limiting rod 601 is fixedly connected to the slag box 5, the installation box 602 is arranged on one side of the limiting rod 601, and the installation box 60 2 is provided with a first sliding groove 603, a gear 605 and a second sliding groove 606, preferably, a roller is provided at one end of the first rack 604, so that the first rack 604 slides in the first sliding groove 603, a roller is provided at one end of the second rack 607, so that the second rack 607 slides in the second sliding groove 606, the first rack 604 is connected through the gear 605 and the second rack 607, a spring 608 is provided between the second rack 607 and the second sliding groove 606, the spring 608 is located in the second sliding groove 606, and one end of the spring 608 is fixed to the second rack 607, and the other end is fixed to the inner wall of the second sliding groove 606. The second rack 607 passes through the through groove 610 and enters the limiting groove 609 to limit the limiting rod 601 and the pushing rod 42.

[0031] When the push cylinder 41 controls the push rod 42 to extend outward, due to the limiting effect of the second rack 607, the limiting rod 601 and the push rod 42 move together, that is, the slag box 5 and the filter plate 51 move together.

[0032] In order to enable the filter plate 51 and the slag box 5 to move relative to each other, it is necessary to release the limiting effect of the limiting mechanism 6. Therefore, a driving device 7 is provided. The driving device 7 is provided at the top of the lifting plate 32. The driving device 7 comprises a fixed block 71, a bevel groove 72, and a flat groove 73. The fixed block 71 is provided at the top of the lifting plate 32. The bevel groove 72 and the flat groove 73 are provided on the fixed block 71. The bevel groove 72 and the flat groove 73 are smoothly connected. The first rack 604 slides in the bevel groove 72 and the flat groove 73.

[0033] When the limiting rod 601 drives the first rack 604 in the limiting box 603 to move to the inclined groove 72, the moving position changes, and the first rack 604 moves toward the limiting rod 601, driving the gear 605 to rotate and the second rack 607 to move away from the limiting rod 601, thereby releasing the limiting effect on the push rod 42 and the limiting rod 601. At this time, the push rod 42 continues to push the filter plate 51 to move away while the slag box 5 does not move, so that the bottom of the slag box 5 is opened. On the contrary, when the push rod 42 pulls the filter plate 51 back to the bottom of the slag box 5, it drives the slag box 5 and the installation box 602 to move back. When the limiting groove 609 and the through groove 610 overlap, under the reset action of the spring 608, the second rack 607 inserts into the limiting block 609 to restore the limit.
