The utility model includes a furnace body, an inclined feeding channel is arranged on the side wall of the furnace body, the inclined feeding channel extends to the outside of the furnace body, and the length of the inclined feeding channel extending outside the furnace body is greater than the length of a single aluminum ingot. The utility model is characterized in that an induction heater is arranged outside the inclined feeding channel outside the furnace body, and an aluminum ingot feeding stepping mechanism and an aluminum ingot feeding advancing mechanism are arranged in front of the inclined feeding channel opening. The utility model is novel and unique in design, avoiding the impact damage to the slag removal slope caused by loading aluminum ingots from the furnace door in the past, making the automatic filling more accurate, reducing the influence of human control factors, and reducing the requirements for the heating capacity of the heater in the furnace.

[0003] In the prior art, the smelting of aluminum ingots usually involves placing a large amount of raw materials into a smelting furnace, which results in a slow internal smelting speed and has certain limitations. Therefore, this article aims to propose an aluminum ingot smelting furnace with an intermittent feeding device, which can intermittently add materials to the smelting furnace, so that the aluminum ingots entering the smelting furnace can be fully melted, thereby improving the efficiency and sufficiency of melting. Utility Model Content

[0004] The technical problem to be solved by the utility model is that in the prior art, the smelting of aluminum ingots usually involves placing a large amount of raw materials into a smelting furnace, which results in a slow internal smelting speed and has certain limitations. In order to improve its shortcomings, the utility model provides an aluminum ingot smelting furnace with an intermittent feeding device.

[0005] In order to achieve the above object, the utility model is realized by the following technical solutions:

[0006] An aluminum ingot smelting furnace with an intermittent feeding device comprises a furnace body, an intermittent feeding device is arranged on the side of the furnace body, the intermittent feeding device comprises a feeding rack, a guide plate inclined downward is arranged in the feeding rack, a rotating shaft is inserted into the feeding rack at the free end of the guide plate, a limiting body that moves integrally is sleeved on the rotating shaft, a torsion spring is sleeved on the rotating shaft, a feeding hole is opened on the side of the furnace body opposite to the free end of the guide plate, when the cylindrical aluminum ingot moves to the free end of the guide plate, the horizontal plane where the central axis of the cylindrical aluminum ingot is located is arranged above the horizontal plane where the axis of the rotating shaft is located.

[0007] As a preferred solution, the limiting body includes a rod body and a fan-shaped body that are integrally arranged, and the rod body and the fan-shaped body cooperate to form a spoon-shaped structure.

[0008] As a preferred solution, one end of the torsion spring is fixedly connected to the rotating shaft, and the other end is fixedly connected to the limiting body.

[0009] As a preferred solution, at least three of the limiting bodies are spaced apart along the axis of the rotating shaft.

[0010] As a preferred solution, an observation window is provided on the front side of the furnace body.

[0011] Compared with the prior art, the beneficial effect of the utility model is that due to the coordinated arrangement of the guide plate and the limit body, in the process of the cylindrical aluminum ingot rolling on the guide plate into the furnace body, the limit body is rotated by the gravity of the cylindrical aluminum ingot itself, and at the same time, the fan-shaped body of the limit body blocks the next aluminum ingot, forming an intermittent feeding method, so that the aluminum ingot entering the smelting furnace can be fully melted, thereby improving the efficiency and sufficiency of melting. The device is suitable for industrial production and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 2 for Figure 1 A partial enlarged view of point A in the middle.

[0014] In the figure: 1 furnace body, 2 feed rack, 3 guide plate, 4 rotating shaft, 5 limit body, 501 rod body, 502 fan-shaped body, 6 torsion spring, 7 feed hole, 8 observation window. DETAILED DESCRIPTION

[0015] The technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-2As shown, an aluminum ingot melting furnace with an intermittent feeding device includes a furnace body 1, an intermittent feeding device is arranged on the side of the furnace body 1, and the intermittent feeding device includes a feeding frame 2, a guide plate 3 inclined downward is arranged in the feeding frame 2, a rotating shaft 4 is inserted on the feeding frame 2 at the free end of the guide plate 3, a limiter 5 that moves integrally is sleeved on the rotating shaft 4, a torsion spring 6 is sleeved on the rotating shaft 4, and a feeding hole 7 is opened on the side of the furnace body 1 opposite to the free end of the guide plate 3. When the cylindrical aluminum ingot moves to the free end of the guide plate 3, the horizontal plane where the central axis of the cylindrical aluminum ingot is located is located above the horizontal plane where the axis of the rotating shaft 4 is located. The limiter 5 includes a rod body 501 and a fan-shaped body 502 that are arranged integrally, and the rod body 501 and the fan-shaped body 502 cooperate to form a spoon-shaped structure. One end of the torsion spring 6 is fixed to the rotating shaft 4, and the other end is fixed to the limiter 5. At least three limiters 5 are arranged at intervals along the axis direction of the rotating shaft 4. An observation window 8 is provided on the front side of the furnace body 1 .

[0017] The operator places a number of cylindrical aluminum ingots on the guide plate 3 of the feed rack 2. The cylindrical aluminum ingots are placed horizontally and roll to the end on the guide plate 3. When the cylindrical aluminum ingots roll to the limit body 5, due to the gravity of the cylindrical aluminum ingots, the limit body 5 is squeezed to rotate clockwise, and the rod body 501 of the limit body 5 rotates to the feed hole 7. At the same time, the cylindrical aluminum ingots roll along the inner surface of the rod body 501 into the furnace body 1. At the same time, the fan-shaped body 502 of the limit body 5 rotates to block the feeding of the next cylindrical aluminum ingot. Due to the reset action of the torsion spring 6, after the current cylindrical aluminum ingot enters the furnace body 1, the limit body 5 resets and rotates counterclockwise, and then the next cylindrical aluminum ingot is fed. The specific gravity of the cylindrical aluminum ingot can overcome the torsion of the torsion spring 6 and squeeze and rotate the limit body 5.

[0018] The present utility model is not limited to the above-mentioned embodiments. On the basis of the technical solution disclosed in the present utility model, technicians in this field can make some substitutions and deformations to some technical features therein according to the disclosed technical content without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
