Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting, in particular to an automatic furnace lining pushing-out system. Background Art

[0002] When an electric furnace is in use, it is necessary to build a lining inside the furnace body as a protective wall of the furnace to protect the furnace body from wear and corrosion, to prevent leakage of molten material inside the furnace body, to improve the quality of metal smelting, and to increase the life of the furnace. The lining will wear and become thinner during the use of the furnace, and the performance of the lining will also decline due to slag. In order to prevent coil damage or furnace leakage accidents caused by the decline in the performance of the lining, the lining needs to be replaced regularly. Before replacing the lining, the lining needs to be pushed out from the bottom of the furnace together with the slag.

[0003] The patent document with application number CN202221392372.X discloses an induction furnace lining ejection device, including a connecting mechanism, which includes a sleeve and a positioning seat. A circular slot is provided on the outer wall of the furnace bottom of the furnace body, the slot is connected to the embedded slot, the sleeve is inserted in the slot, and the outer wall of the sleeve is welded and fixed to the inner wall of the slot, and the positioning seat is integrally formed at the end of the sleeve away from the furnace body. In this embodiment, the positioning seat is a square block, and a positioning slot is provided on the side wall of the positioning seat away from the furnace body. A through hole is provided on the inner wall of the positioning slot close to the furnace body, and the through hole is coaxial with the slot. The cylinder barrel at one end of the piston rod of the ejection cylinder is installed in the positioning slot, and the piston rod of the ejection cylinder is connected to the ejection block through the through hole and the sleeve. The positioning seat is different from the positioning groove and has a limiting groove running through the side wall. The limiting groove is connected to the positioning groove. The limiting groove includes a mounting portion and a limiting portion. The mounting portion is opened close to the furnace body, and the limiting portion is opened at the bottom of the mounting portion away from the furnace body. The limiting portion is a semicircular groove. The limiting columns are integrally formed on both sides of the outer wall of the cylinder barrel of the push-out oil cylinder. The limiting columns pass through the mounting portion and are clamped in the limiting portion, and have an interference fit with the limiting portion, thereby realizing the detachable fixation of the push-out oil cylinder and the connecting mechanism. In this technical solution, it is inconvenient to hoist the push-out oil cylinder during installation. When the magnetic part is separated from the push-out block, the push-out oil cylinder will rotate around the limiting axis, thereby causing the push-out oil cylinder to be non-concentric with the penetration hole, so that the push-out oil cylinder needs to be manually straightened when the telescopic cylinder of the push-out oil cylinder retracts.

[0004] The patent document with application number CN201921074519.9 discloses a furnace lining push-out mechanism assembly that can be quickly disassembled and assembled. The furnace lining push-out mechanism assembly that can be quickly disassembled and assembled connects the furnace lining push-out mechanism with the furnace lining push-out port, eliminating the interconnection operation between the pin shaft connection hole and the pin shaft screw. The connection is convenient, efficient and easy to operate. At the same time, it avoids the structural jamming phenomenon caused by thermal deformation between the connection structures, greatly improving the efficiency of the furnace lining push-out operation and the overall efficiency of production. However, during installation, the connector needs to be clamped in the plug interface, and the push-out mechanism needs to be manually straightened for installation, which is time-consuming and laborious.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0035] Example 1: Reference Figure 1-Figure 2 As shown, the automatic lining ejection system comprises a furnace body 1, a furnace lining 15 is installed in the furnace body 1, a top plate 6 is inlaid and fixed at the bottom of the furnace lining 15, a blind hole 7 is provided on the top plate 6, a through hole 5 concentric with the top plate 6 is provided at the bottom of the furnace body 1, and the through hole 5 is connected with the blind hole 7. The top plate 6, the blind hole 7 and the through hole 5 are concentric.

[0036] Ear plates 2 are fixed to the lower end of the furnace body 1 on both sides of the through hole 5, and mounting grooves 3 are provided on the ear plates 2. The mounting grooves 3 include a mounting section whose length direction is perpendicular to the axial direction of the furnace body 1 and a clamping section whose length direction is parallel to the axial direction of the furnace body 1. The two ear plates 2 are fixedly connected by a connecting rod 4, and the connecting rod 4 is located above the telescopic cylinder 8. The mounting section of the mounting groove 3 is located between the furnace body 1 and the connecting rod 4.

[0037] Two pins 9 are fixed on the cylinder body of the telescopic cylinder 8, and the pins 9 are located in the clamping section of the mounting groove 3 on one side thereof. The telescopic cylinder 8 is concentric with the through hole 5, and a fixing plate 10 is fixed on the telescopic rod of the telescopic cylinder 8, and a lifting ring 11 corresponding to the blind hole 7 is fixed on the fixing plate 10.

[0038] A hook 14 is slidably provided on the cylinder body of the telescopic cylinder 8, and the hook 14 is hooked on the connecting rod 4. Specifically, a slide groove 12 is provided on the cylinder body of the telescopic cylinder 8, and the length direction of the slide groove 12 is parallel to the axial direction of the telescopic cylinder 8. A slider 13 is slidably engaged in the slide groove 12, and the hook 14 is fixed on the slider 13.

[0039] The hook 14 includes a connecting section whose length direction is perpendicular to the axial direction of the telescopic cylinder 8 and a stabilizing section whose length direction is parallel to the axial direction of the telescopic cylinder 8. The connecting section is fixedly connected to the slider 13, and the connecting rod 4 is located between the stabilizing section and the telescopic cylinder 8, and the stabilizing section is in contact with the connecting rod 4.

[0040] When the furnace lining 15 needs to be ejected, the furnace body 1 is rotated until the axis is parallel to the horizontal plane. Then the telescopic cylinder 8 is lifted by the cooperation of the lifting equipment and the lifting ring 11. After being lifted, the telescopic cylinder 8 is in a vertical state. Then the telescopic cylinder 8 is moved by the lifting equipment, and the lower end of the telescopic cylinder 8 passes through between the two ear plates 2 and then moves downward. The pin rod 9 enters the clamping section of the mounting groove 3 through the mounting section of the mounting groove 3. Then the telescopic cylinder 8 is rotated 90 degrees around the pin rod 9.
