Description

Technical Field

[0001] This utility model relates to the field of brown fused alumina production, specifically a ladle moving platform for discharging material from a tilting furnace. Background Technology

[0002] Brown fused alumina is a brownish-red synthetic corundum produced by smelting bauxite and coke (anthracite) at high temperatures and then cooling and crystallizing. Its main component is α-Al₂O₃ (content ≥ 95%), with small amounts of impurities such as iron, silicon, and titanium. It has a Mohs hardness of 9.0, second only to diamond and silicon carbide, and is characterized by high hardness, high toughness, high temperature resistance, and strong chemical stability. During the production of brown fused alumina, a mobile platform is used to move and tilt the furnace containing the smelting raw materials.

[0003] For example, authorization announcement number CN218754499U discloses a ladle moving platform for discharging material from a tilting furnace, including a hanging plate and a base plate. A sling mechanism is provided at the top of the hanging plate, and a first hydraulic cylinder is fixedly installed at the bottom left end of the hanging plate. A connecting mechanism is provided at the bottom end of the piston rod of the first hydraulic cylinder, and the bottom end of the piston rod is connected to the furnace body via the connecting mechanism. Horizontal columns are integrally formed at both the front and rear ends of the furnace body, and a relative rotation mechanism is provided on the side wall of the horizontal column. A vertical rod is connected to the side wall of the horizontal column via the relative rotation mechanism. This utility model uses a sliding mechanism to connect a bearing seat to the top of the base plate, and a second hydraulic cylinder is hinged to the top of the bearing seat. A connecting plate is hinged to the horizontal columns on both the front and rear sides of the furnace body via a pin. When the first hydraulic cylinder is not driving the furnace body, the second hydraulic cylinder is in a vertical position, working in conjunction with the sling mechanism to support the furnace body, sharing the lifting weight of the sling mechanism, ensuring the service life of the overall structure, and eliminating the need for frequent replacements.

[0004] In the aforementioned technology, the tilting structure of the mobile platform is connected to the furnace body via a rope. However, the rope is prone to breakage due to prolonged use in high-temperature environments, causing raw materials to spill out when the furnace body is tilted, posing a safety hazard. Therefore, there is an urgent market need to develop a ladle mobile platform for tilting furnace discharge to help solve the existing problems. Utility Model Content

[0005] The purpose of this utility model is to provide a ladle moving platform for discharging material from a tilting furnace, in order to solve the problem mentioned in the background art where the tilting structure of the moving platform is connected to the furnace body by a rope, but the rope is prone to breakage due to long-term use in a high-temperature environment, causing raw materials to spill out when the furnace body is tilted, which poses a safety hazard.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a ladle moving platform for discharging material from a tilting furnace, comprising a moving platform 1. Four track wheels 101 are arrayed on the lower end face of the moving platform 1. The moving platform 1 moves the furnace body along the track via the four track wheels 101. Support columns 102 are fixedly connected to the rear ends of both sides of the upper end of the moving platform 1. L-shaped rotating arms 2 are rotatably connected to the upper ends of the two support columns 102. The rear ends of the L-shaped rotating arms 2 are rotatably connected to the upper ends of the support columns 102 via a second rotating shaft 201, allowing the L-shaped rotating arms 2 to rotate around the second rotating shaft 201. Second rotating connectors 202 are rotatably connected to the lower ends of the front ends of the two L-shaped rotating arms 2. The upper end face of the moving platform 1 is connected to the two support columns 102. 2. A rotating seat 103 is fixedly connected to each of the two front ends. A first rotating connector 104 is rotatably connected to each of the two rotating seats 103. A hydraulic rod 3 is provided between each of the two first rotating connectors 104 and the two second rotating connectors 202. The first rotating connector 104 is rotatably connected to the rotating seat 103 through a first rotating shaft 105. The second rotating connector 202 is rotatably connected to the L-shaped rotating arm 2 through a third rotating shaft 203. The lower end of the hydraulic rod 3 is fixedly connected to the upper end of the first rotating connector 104. The upper end of the telescopic end of the hydraulic rod 3 is fixedly connected to the lower end of the second rotating connector 202. The two hydraulic rods 3 synchronously push the L-shaped rotating arm 2 to rotate upward around the second rotating shaft 201.

[0024] Please see Figure 2 and Figure 4 Two L-shaped rotating arms 2 are fixedly connected at their rear ends to a lifting plate 4. A furnace body 5 is provided at the front end of the lifting plate 4. Tilting lifting plates 401 are fixedly connected to both sides of the lifting plate 4 and the front end of the middle of both sides of the furnace body 5. Limit slots 402 are provided at the front end of both tilting lifting plates 401. The two lifting columns 502 are respectively inserted into the two limit slots 402. When the two L-shaped rotating arms 2 rotate upward, they synchronously drive the lifting plate 4 and the two tilting lifting plates 401 to rotate upward, thereby causing the two tilting lifting plates 401 to synchronously drive the furnace body 5 to rotate upward and tilt. At the same time, the lifting plate 4 supports the lower end of the furnace body 5 in the tilting direction.

[0025] Please see Figure 3 The furnace body 5 has a tilting port 501 at the rear end of its upper end. A support rod 6 is fixedly connected to the middle of the rear end of the upper surface of the moving platform 1 and to the rear end of the lifting plate 4. A guide bucket 601 is rotatably connected to the upper end of the support rod 6. The front end of the lower end of the guide bucket 601 is rotatably connected to the upper end of the support rod 6 through a damping shaft 602. The raw materials inside the furnace body 5 are poured into the guide bucket 601 through the tilting port 501 and then flow out through the guide bucket 601. The guide bucket 601 extends the tilting port 501. The guide bucket 601 is rotated on the support rod 6 through the damping shaft 602 to adjust the direction of the outlet at the rear end of the guide bucket 601, so as to facilitate the flow in different directions.

[0026] Working Principle: During operation, the mobile platform 1 moves along the track to the designated position via four track wheels 101. Then, the two hydraulic rods 3 operate synchronously. The telescopic ends of the hydraulic rods 3 push the second rotating connector 202 upwards, causing the L-shaped rotating arm 2 to rotate upwards around the second rotating shaft 201. Simultaneously, the lifting plate 4, fixed between the two L-shaped rotating arms 2, rises synchronously. Through the limiting slot 402 at the front end of the tilting lifting plate 401, it drives the lifting columns 502 on both sides of the furnace body 5 upwards, causing the furnace body 5 to tilt backwards with the lifting columns 502 as the fulcrum. Molten brown corundum material inside the furnace body 5 flows out from the pouring port 501 to the guide hopper 601. Before pouring, the operator can manually adjust the damping shaft 602 to align the outlet of the guide hopper 601 with the ladle position. After pouring, the hydraulic rods 3 retract, and the L-shaped rotating arms 2 reset, restoring the furnace body 5 to a horizontal state. The entire process uses rigid connectors instead of traditional steel wire ropes, avoiding the risk of breakage in high-temperature environments. Furthermore, the towing plate 4 and the tilting lifting plate 401 form a double support structure, ensuring a stable and reliable tilting process.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
