In converter blowing, in order to maintain the temperature balance of a hearth, a residual pole stack of cold materials is required to be added into the converter. The addition of the stack is mainly determined by the furnace condition, and the addition also dynamically changes along with the change of the furnace condition. In order to meet the furnace conditions, further improve the thermal efficiency of converter converting and facilitate more accurate control of productivity, it is required to accurately control the accumulated amount of the stacks added into the furnace, so that the added amount of the stacks approximates to the actual required amount of the furnace conditions.

In the related art, the accumulated amount of the residual anode feeder added into the stack is controlled manually by an operator, so that the added amount of the stack approaches the actual required amount of the furnace condition as much as possible. The weight of each pile of materials is equal, so that the compression difficulty of the pile of materials is increased; or the weights of the single stacking materials distributed on the charging machine are different, and the accumulated amount of the stacking materials added into the converter by the anode scrap charging machine is controlled only by manual experience, so that the difference between the accumulated weight of the stacking materials added into the converter and the actual required amount of the furnace condition is larger, the heat efficiency of the converter is reduced, the accurate control of the productivity of the converter is not facilitated, and the energy conservation is also not facilitated.

Based on this, the application proposes a anode scrap feeder 100 for feeding a stack 200 into a metallurgical furnace (such as a converter), which can improve the disadvantage of inaccurate accumulation of the stack 200 added into the metallurgical furnace, so that the accumulation of the stack 200 is adaptively close to the actual demand of the furnace, thereby not only improving the thermal efficiency of the metallurgical furnace, but also being beneficial to precisely controlling the productivity and saving energy.

The anode scrap feeder 100 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

Referring to fig. 1, a anode scrap feeder 100 according to an embodiment of the present invention may include: a conveyor 10 and a weighing device 20.

Specifically, the conveyor 10 is used to convey the stacks 200 and to deliver the stacks 200 to a metallurgical furnace. The weighing device 20 is disposed corresponding to the conveying device 10, and the weighing device 20 is used for weighing the stack 200. Wherein the conveyor 10 is arranged to be able to deliver a target number of stacks 200 to the metallurgical furnace according to the weighing result of the weighing device 20.

In use, the stacks 200 may be placed on the conveyor 10 and the weight of each stack 200 is weighed by the weighing device 20, the weighing device 20 recording the instantaneous and cumulative amounts of the stacks 200 in real time and transmitting the data to the control system, or the control system connected to the weighing device 20 recording the instantaneous and cumulative amounts of the stacks 200 in real time; after the stacking materials 200 are aligned on the conveying device 10, the stacking materials are conveyed by the conveying device 10 in a spacing arrangement mode, such as fixed spacing arrangement conveying; at this time, the anode scrap feeder 100 (e.g., control system) can automatically calculate and select the feeding amount of the stack 200 closest to the current furnace condition in real time, i.e., calculate the target amount, by comparing the required feeding amount of the metallurgical furnace with the weight data of the stack 200 distributed on the conveyor 10 after weighing, and then the conveyor 10 feeds the target amount of the stack 200 into the metallurgical furnace.

Thus, the anode scrap feeder 100 can adaptively adjust the addition of the stacking amount in real time according to the stacking amount distributed on the conveying device 10 and the required addition amount of the furnace condition. The addition amount of the stacking material 200 is more matched with the furnace condition, so that the temperature balance in the metallurgical furnace is maintained, the thermal efficiency of the metallurgical furnace is improved, and the productivity is controlled accurately.

In the above embodiment, the position of the weighing device 20 with respect to the conveying device 10 is not limited. For example, in the conveying direction, the weighing device 20 may be disposed at the beginning, middle or end of the conveying device 10, so that the anode scrap feeder 100 can adaptively adjust the feeding amount of the stacks 200 by only weighing each stack 200.

The weighing device 20 can be flexibly arranged relative to the arrangement of the conveying device 10. For example, the weighing device 20 may be installed in the conveyor 10, above the conveyor 10, below the conveyor 10, or the like, as long as the weight of the stack 200 on the conveyor 10 can be weighed.

The manner in which the conveyor 10 feeds the stacks 200 into the metallurgical furnace is not limited. For example, the end of the conveyor 10 may be positioned above the metallurgical furnace and the stack 200 naturally falls out of support of the conveyor 10 into the metallurgical furnace as it is conveyed to the end as the conveyor 10 moves; alternatively, the anode scrap feeder 100 may include a transfer device for transferring the stack 200 on the conveyor 10 into a metallurgical furnace, such as a robot, swing arm, or the like.

According to the anode scrap feeder 100 of the embodiment of the invention, the weight of each stacking material 200 on the conveying device 10 is weighed by the weighing device 20, and the conveying device 10 can throw the stacking materials 200 with target quantity into the metallurgical furnace according to the weighing result, so that the throwing quantity of the stacking materials 200 is closer to the required quantity of the metallurgical furnace condition, and the anode scrap feeder 100 has the function of self-adaptively adjusting the adding quantity of the stacking materials 200, thereby not only improving the thermal efficiency of the metallurgical furnace, but also being beneficial to accurately controlling the productivity and saving energy.

According to some embodiments of the present invention, as shown in fig. 1-5, a conveyor 10 includes a support 11, the support 11 being operable to carry a stack 200 during conveyance. Here, the "support 11" refers to a structure capable of supporting the stack 200 to perform the conveyance of the stack 200, including, but not limited to, a belt shape, a plate body, a net plate, a chain, etc., or a combination of at least two of the foregoing structures.

In addition, as shown in fig. 3 and 5, the support 11 is provided with a relief hole 111, and the relief hole 111 is a through hole penetrating the support 11 perpendicular to the conveying direction, and the through hole may be square, round, irregular, or the like.

As shown in fig. 2 to 4, the weighing device 20 includes: a support 21 and a load cell 22. Wherein the supporting part 21 can be lifted and lowered relative to the conveying device 10. Specifically, the supporting portion 21 may be raised to pass through the escape hole 111 to prop up the stack 200, and the supporting portion 21 may be lowered to a top surface of the supporting portion 21 below the supporter 11. The load cell 22 is connected to the support 21, and the load cell 22 is used to weigh the stack 200 supported by the support 21.

When the stack 200 is required to be weighed, the supporting portion 21 may be lifted until the supporting portion 21 passes through the avoiding hole 111 and supports the stack 200 to be weighed, that is, separates the stack 200 to be weighed from the supporting member 11; at this time, the load cell 22 may weigh the supported stack 200 to avoid interference from the support 11 during the weighing process. After the weighing is completed, the supporting part 21 can be lowered until the top surface of the supporting part 21 is lower than the supporting part 11, that is, the supporting part 21 and the supporting part 11 are completely free from interference in the conveying direction; at this time, the stacking material 200 is placed on the supporting member 11 again, and the stacking material 200 can be conveyed to the next station by the supporting member 11, so as to avoid the interference of the supporting portion 21 to the conveying process.

In the above-described embodiment, the placement position of the load cell 22 with respect to the support portion 21 is not limited. For example, the load cell 22 may be provided on top of the supporting portion 21, that is, the supporting portion 21 contacts the stack 200 through the load cell 22 and supports the stack 200, and the load cell 22 may directly weigh the stack 200; for another example, the load cell 22 may be disposed at the bottom or the middle of the supporting portion 21, that is, the load cell 22 weighs the stack 200 and at least a portion of the supporting portion 21, thereby indirectly weighing the stack 200, which is within the scope of the present invention.

Wherein, the lower ends of the plurality of support rods 211 are connected with the weighing platform 212, and the upper ends of the plurality of support rods 211 are used for supporting the stacking material 200. The load cell 22 is disposed on the underside of the weigh platform 212.

In other words, each stack 200 is supported by the plurality of support bars 211, which is advantageous in improving the support stability of the stack 200. By providing the weighing platform 212 between the load cell 22 and the plurality of support rods 211, the force of the plurality of support rods 211 can be uniformly transmitted to the load cell 22, thereby improving the accuracy of weighing. For example, weigh platform 212 may be a flat plate.

At least two of the plurality of support rods 211 may be arranged at intervals in the conveying direction, and at least two may be arranged at intervals perpendicular to the conveying direction (e.g., at intervals in the left-right direction), so that the stability improving effect is better. For example, the plurality of support rods 211 may be arranged in a matrix.

The number of the weighing sensors 22 can be one or more, wherein a plurality of the weighing sensors 22 can be in contact with the weighing platform 212, so that weighing can be performed through the plurality of the weighing sensors 22, and the weighing precision is improved.

In some embodiments of the present invention, as shown in fig. 2-4, the weighing device 20 further includes a driving member 23, and an output end of the driving member 23 is used to drive the supporting portion 21 to lift. For example, the driving member 23 may be a driving cylinder, and the output end may be a telescopic shaft or the like. By arranging the driving piece 23, the supporting part 21 can be automatically lifted, so that automatic weighing is realized, and the efficiency is improved.

In some embodiments, the weighing apparatus 20 further comprises: a base 24 and a guide bar 25. The driver 23 is mounted on a base 24, and the base 24 is provided with a guide hole extending in the lifting direction of the support 21. The guide rod 25 is connected to at least one of the support 21 and the load cell 22, and the guide rod 25 is disposed through the guide hole and movable along the guide hole.

For example, the guide bar 25 may be connected to the support portion 21 to guide the lifting of the support portion 21; or the guide rod 25 is connected with the load cell 22 to be indirectly connected with the support part 21, thereby guiding the lifting of the support part 21; of course, the guide bar 25 may be connected to both the support 21 and the load cell 22, which is within the scope of the invention.

In the lifting process of the supporting part 21, the supporting part 21 is ensured to stably lift along the required lifting direction by moving along the guide hole through the connected guide rod 25, the clamping is not easy to occur, and the smooth supporting of the stacking material 200 and the releasing of the stacking material 200 are ensured.

In some embodiments, as shown with continued reference to fig. 2-5, the top of the output end is provided with a top plate 26, and the output end is connected to a middle portion of the top plate 26. The weighing sensor 22 is uniformly arranged on the top plate 26, the guide rods 25 are multiple, the guide rods 25 are symmetrically arranged about the output end, and the guide rods 25 are connected with the top plate 26.
