Description

Technical Field

[0001] This utility model relates to the field of non-ferrous metal smelting equipment technology, and more specifically, to a chute for continuously discharging hot matte. Background Technology

[0002] In copper pyrometallurgical processes, the settling electric furnace is a core piece of equipment for achieving key separation processes. Its main function is to settle the mixture generated during smelting, thereby effectively separating matte from slag and significantly reducing the copper content in the slag, thus minimizing the loss of valuable metals. The matte separated in the settling electric furnace needs to be transported via chutes to corresponding matte ladles, and then transferred to the next processing stage. The chutes used to guide the matte transport are crucial supporting components that ensure the continuous operation of the transfer process.

[0003] Currently, for the discharge of hot matte, the industry generally uses two independent, inclined chutes at the bottom or side of the electric furnace. The hot matte, under its own weight, flows through these chutes into corresponding matte ladles placed below, completing the collection and transfer of matte. However, when a matte ladle is full, the discharge operation of the corresponding chute must be paused to replace it with an empty ladle. To prevent leakage of residual hot matte in the chute or from the continuous flow of hot matte from the furnace, the existing method typically involves temporarily sealing the outlet of the chute with refractory mud. This sealing method poses serious safety risks. High-temperature matte is prone to splashing due to untimely or incomplete sealing, or operational disturbances, potentially burning on-site operators and damaging surrounding equipment. Furthermore, the operation is cumbersome, requiring operators to be in close contact with the high-temperature chute during the sealing process, resulting in high workload and low efficiency. Meanwhile, normal discharge cannot be achieved during the blocking of a single chute. Even if two chutes are blocked alternately and the matte ladle is replaced, the overall discharge efficiency will still decrease, which will easily cause matte to accumulate in the electric furnace, restrict the smelting rhythm, and affect the continuity of production. Utility Model Content

[0004] The purpose of this invention is to provide a chute for continuous discharge of hot copper matte, which solves the problems of safety risks, cumbersome operation and discharge interruption when existing chutes are blocked.

[0005] This utility model is achieved through the following technical solution: a chute for continuously discharging hot matte, including a first flow channel and a second flow channel, the first flow channel and the second flow channel are interconnected and intersecting each other, a guide plate is hinged at the intersection of the side walls of the first flow channel and the second flow channel for switching the outlet of the first flow channel and / or the outlet of the second flow channel, the guide plate is in sealed contact with the inner walls of the first flow channel and the second flow channel, a locking rod is inserted into the free end of the guide plate, and a locking groove is opened at the bottom of the first flow channel and the second flow channel, the locking rod is inserted into the locking groove for engagement.

[0006] Furthermore, the end of the guide plate has a slot for movably inserting the locking rod, and several locking slots are arranged along the arc-shaped trajectory swept by the slot.

[0007] Furthermore, inclined grooves are respectively opened on both sides of the bottom of the guide plate, and wedge-shaped sealing strips that contact the inclined surfaces of the inclined grooves are respectively installed in the first flow channel and the second flow channel.

[0008] Furthermore, a toggle handle is provided at the top of the guide plate.

[0009] Furthermore, the top of the locking lever extends beyond the upper edge of the guide plate.

[0010] Furthermore, the guide plate is interference-fitted with the first flow channel and the second flow channel respectively.

[0011] Furthermore, the guide plate is made of chromium-nickel alloy.

[0012] This utility model has at least the following advantages and beneficial effects: by setting up a first flow channel and a second flow channel that are interconnected and intersecting, and hinged a guide plate that can switch the direction of conduction at the intersection, combined with the positioning cooperation of the locking rod and the locking groove, the flow channel conduction state can be stably switched by the guide plate without temporary blocking. This not only avoids the safety risks and cumbersome operations of high-temperature copper matte splashing, but also allows for the switching of flow channels by rotating the guide plate when changing the copper matte ladle, realizing continuous discharge of hot copper matte, eliminating the problem of discharge interruption caused by the pause of a single chute, effectively ensuring the continuity of the smelting process, and improving operational safety and overall efficiency.

[0019] The specific implementation method is described below with reference to the accompanying drawings.

[0020] Example like Figures 1 to 5 As shown, this embodiment mainly discloses a chute for continuously discharging hot copper matte, including a first flow channel 1 and a second flow channel 2. The first flow channel 1 and the second flow channel 2 are interconnected and intersected. The side walls of the first flow channel 1 and the second flow channel 2 are hinged with guide plates 3 for switching the conduction of the outlet of the first flow channel 1 and / or the outlet of the second flow channel 2. The guide plates 3 are in sealed contact with the inner walls of the first flow channel 1 and the second flow channel 2. A locking rod 4 is inserted into the free end of the guide plate 3 for limiting. A locking groove 10 is opened at the bottom of the intersection of the first flow channel 1 and the second flow channel 2. The locking rod 4 is inserted into the locking groove 10 for engagement. Specifically, the inlet ends of both the first flow channel 1 and the second flow channel 2 are connected to the existing settling electric furnace. A matte ladle is placed below its outlet end. When one matte ladle is full, there is no need to pause discharge; simply rotating the guide plate 3 switches to the other flow channel. For example, when the matte ladle corresponding to the first flow channel 1 is full, simply move the guide plate 3 to one side of the first flow channel 1, making the guide plate 3 in sealed contact with the inner wall of the first flow channel 1. At this time, the matte from the first flow channel 1 and the second flow channel 2 converges at the intersection and flows from the outlet of the second flow channel 2 to the matte ladle corresponding to the second flow channel 2, achieving continuous discharge of hot matte. This avoids the risk of splashing and cumbersome operation caused by mud blockage, eliminates the discharge interruption caused by pausing a single chute, ensures the continuity of the smelting process, and improves operational safety and efficiency. The locking rod 4 and the locking groove 10 cooperate to lock the position of the free end of the guide plate 3, ensuring stable positioning of the guide plate 3.

[0021] Furthermore, in a specific implementation, the guide plate 3 provided in this embodiment of the present invention has an insertion groove 30 at its end for movably inserting and locking the rod 4, and several locking grooves 10 are arranged along the arc-shaped trajectory swept by the insertion groove 30. Specifically, by cooperating with the locking rod 4 and the locking grooves 10 at different positions, the relative flow rate of the outlet of the first flow channel 1 and the outlet of the second flow channel 2 can be adjusted.

[0022] Furthermore, in a specific implementation, inclined grooves 31 are respectively provided on both sides of the bottom of the guide plate 3 provided in this embodiment of the utility model, and wedge-shaped sealing strips 11 that contact the inclined surfaces of the inclined grooves 31 are respectively provided in the first flow channel 1 and the second flow channel 2. Specifically, the inclined grooves 31 and the wedge-shaped sealing strips 11 cooperate to extend the leakage path between the first flow channel 1, the second flow channel 2 and the bottom of the guide plate 3, reduce the leakage of hot copper matte from the contact gap, further reduce safety risks, and ensure the safety of the operating environment.

[0023] Furthermore, in a specific implementation, a lever handle 32 is provided at the top of the guide plate 3 provided in this embodiment of the present invention. Specifically, the lever handle 32 facilitates the operator to rotate the guide plate 3. In addition, an iron chain can be connected to the end of the lever handle 32. After rotating to the correct position, the iron chain can be bound to further fix the position of the guide plate 3.

[0024] Furthermore, in specific implementations, the top of the locking rod 4 provided in this embodiment of the present invention extends beyond the upper edge of the guide plate 3. This facilitates the insertion and removal of the locking rod 4. In actual operation, the surface of the guide plate 3 may have a small amount of copper matte adhering to it due to high temperature or a high temperature. The extended part is convenient for the operator to hold or use tools (such as long hooks) to insert and remove it, without having to put their hands close to the high-temperature area of ​​the guide plate 3. This reduces the risk of burns and makes the locking operation more effortless and efficient, ensuring that the guide plate 3 can be quickly fixed after switching, reducing operation time.

[0025] Furthermore, in specific implementations, the guide plate 3 provided in this embodiment of the present invention is interference-fitted with the first flow channel 1 and the second flow channel 2, respectively. This ensures that the guide plate 3 is in close contact with the first flow channel 1 and the second flow channel 2, effectively preventing hot matte from leaking out from the contact point. At the same time, the interference fit enhances the impact resistance of the guide plate 3 within the flow channel, preventing the guide plate 3 from shaking due to the impact force of the matte flow, and ensuring a stable working state after flow channel switching.

[0026] Furthermore, in specific implementations, the guide plate 3 provided in this embodiment of the present invention is made of a chromium-nickel alloy. Chromium-nickel alloys possess excellent high-temperature resistance and oxidation resistance, enabling them to withstand the high-temperature corrosion of matte for extended periods without easily deforming, oxidizing, or being damaged. This significantly extends the service life of the guide plate 3 and reduces the frequency of downtime maintenance due to component wear. In addition, this alloy material has high strength, capable of withstanding the stress during the rotation of the guide plate 3 and the impact load of the matte, ensuring that the guide plate 3 maintains structural stability during long-term, frequent switching operations and guaranteeing the reliable operation of the chute.
