Description

Technical Field

[0001] This utility model relates to the technical field of copper smelting equipment, and in particular to a copper outlet sleeve. Background Technology

[0002] In copper smelting, a blowing furnace is used to heat solid copper raw materials into liquid copper. The liquid copper is then refined and impurities removed to obtain the desired molten copper. Finally, the molten copper is discharged through a discharge port to produce copper ingots, copper rods, and other products. To avoid the effects of high temperatures, a water jacket is usually installed at the discharge port. Cooling water is circulated through the water jacket to prevent high temperatures from affecting it. For example, Chinese Patent Application No. 202210631355.5 discloses a copper discharge channel for a top-blown smelting furnace, including a siphon channel located on the furnace wall and a channel located outside the furnace wall. The copper outlet is a detachable copper outlet, and the center line of the siphon channel coincides with the center line of the copper outlet. The siphon channel is an inclined channel that starts from the junction of the furnace wall and the furnace bottom, passes through the furnace wall and connects to the furnace hearth, and has an inclination angle of 15-20°. Plate-type copper water jackets are built on both sides of the channel, and its outlet end is machined on a right-angled trapezoidal refractory brick. The copper outlet is a circular channel located on the extension line of the siphon channel, including a circular through hole set in the center of the base refractory brick and a circular through hole set in the center of the frustum refractory brick. The base refractory brick is fitted with a first copper water jacket, and the frustum refractory brick is fitted with a second copper water jacket. In practical use, although the inner side of the second copper water jacket is equipped with a frustoconical refractory brick, after a period of use, the refractory brick cracks or is washed away by the molten copper, causing the frustoconical refractory brick to break. At this time, the molten copper will come into contact with the copper outlet water jacket. Since the copper outlet water jacket is mostly made of copper, the molten copper will corrode the outer edge of the copper outlet water jacket, causing the copper outlet water jacket to break and the internal cooling water to flow out. After contacting the molten copper, it will be rapidly vaporized, causing a blowout and threatening the safety of workers working nearby. Therefore, a copper outlet water jacket is needed, which has an alloy layer on the outer edge of the copper outlet. The melting point of the alloy layer is higher than that of copper, so that the molten copper is less likely to cause corrosion after contact with it, thus improving the service life of the copper outlet water jacket. Utility Model Content

[0003] To address the aforementioned issues, this invention proposes a copper outlet water jacket, which has an alloy layer on the outer edge of the copper outlet. The alloy layer has a higher melting point than copper, making it less prone to corrosion when molten copper comes into contact with it, thus improving the service life of the copper outlet water jacket.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a copper outlet water jacket, comprising: a water jacket body, a copper outlet channel, a pre-embedded pipe, and a copper outlet water jacket embedded brick. The copper outlet channel is arranged laterally in the middle of the water jacket body and is conical inside. The pre-embedded pipe is pre-embedded in the middle of the water jacket body and surrounds the outside of the copper outlet channel. The copper outlet water jacket embedded brick is tightly fitted to the inner wall of the copper outlet channel. A groove is provided on one side of the copper outlet channel, and an alloy layer is provided on the groove, which wraps around the outer edge of one side of the copper outlet channel.

[0006] Furthermore, the interior of the groove is conical, and the alloy layer is fixed to the groove by welding.

[0007] Furthermore, the copper-releasing channel passes through the alloy layer, and the inner wall of the alloy layer is flush with the inner wall of the water jacket body.

[0008] Furthermore, the water jacket body and the pre-embedded pipe are made of copper, and the alloy layer is made of 304 stainless steel.

[0009] Furthermore, the grooved water jacket body is provided with a threaded sleeve, which is pre-embedded on the water jacket body and is made of 304 stainless steel.

[0010] Furthermore, the embedded pipe has a distance of 20mm to 30mm from the copper placement channel in the middle, and the embedded pipe has a bent part in the middle, which bends towards the copper placement channel.

[0011] The beneficial effects of this utility model are as follows: By setting a groove on one side of the copper discharge channel and then using a welding method to deposit an alloy layer on the groove, the alloy layer covers the edge of the copper discharge channel, which can reduce the scouring of the copper liquid on the edge of the copper discharge channel during copper discharge, reduce the rate of corrosion of the water jacket body, and increase the service life of the copper discharge outlet water jacket, thereby reducing the frequency of downtime to replace the copper discharge outlet water jacket and improving production efficiency.

[0012] It has an alloy layer on the outer edge of the copper outlet. The alloy layer has a higher melting point than copper, so the copper liquid is less likely to corrode it after contact, thus improving the service life of the copper outlet water jacket. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Throughout the description, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0020] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" and "second" may explicitly or implicitly include at least one of the stated features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0021] like Figures 1 to 4 As shown, an embodiment of this utility model provides a copper outlet water jacket, including: a water jacket body 1, a copper outlet channel 2, a pre-embedded pipe 3, and a copper outlet water jacket embedded brick 4. The copper outlet channel 2 is arranged horizontally in the middle of the water jacket body 1 and is conical inside. The pre-embedded pipe 3 is pre-embedded in the middle of the water jacket body 1 and surrounds the outside of the copper outlet channel 2. The copper outlet water jacket embedded brick 4 is tightly fitted to the inner wall of the copper outlet channel 2. A groove is provided on one side of the copper outlet channel 2, and an alloy layer 5 is provided on the groove. The alloy layer 5 wraps around the outer edge of one side of the copper outlet channel 2.

[0022] The water jacket body 1 is installed at the copper outlet of the copper smelting furnace. During smelting, the copper outlet channel 2 is sealed with plugging mud. When copper is discharged, oxygen is burned to open the plugging mud. The high temperature during oxygen burning damages the water jacket body 1 and the copper outlet water jacket embedded brick 4 on this side. Therefore, the copper outlet water jacket of this application has a groove on this side of the copper outlet channel 2. At the same time, an alloy layer 5 is built into the groove by welding. After welding, the alloy layer 5 is polished to form a compliant size. The alloy layer 5 protects the edge of the copper outlet channel 2. When copper is discharged, it can slow down the scouring and erosion rate of the copper liquid at this position, avoid the explosion caused by the corrosion of the pre-embedded pipe 3, and greatly extend the service life of the water jacket body 1. During operation, the worker only needs to replace the copper outlet water jacket embedded brick 4 periodically. The difficulty of replacing the copper outlet water jacket embedded brick 4 and the reduction required are much lower than replacing the water jacket body 1, thereby reducing downtime, improving equipment production efficiency, and reducing operating costs.

[0023] Specifically, such as Figure 3 As shown, the inside of the groove is conical. The alloy layer 5 is fixed to the groove by welding. First, the steel billet of the alloy layer 5 is welded on the groove with a red welding rod. Then, it is milled by machining equipment to form the alloy layer 5. The alloy layer 5 formed by welding is tightly connected to the water jacket body 1, which prevents the copper liquid from seeping between the water jacket body 1 and the alloy layer 5 through the gap when copper is poured, thus ensuring a tight connection between the water jacket body 1 and the alloy layer 5.

[0024] Preferably, the copper discharge channel 2 passes through the alloy layer 5, and the inner wall of the alloy layer 5 is flush with the inner wall of the water jacket body 1, so that the copper discharge port water jacket embedded brick 4 can be tightly installed inside the copper discharge channel 2, and the copper liquid can be reduced from scouring the inner wall of the copper discharge channel 2 by the copper discharge port water jacket embedded brick 4.

[0025] Specifically, the water jacket body 1 and the embedded pipe 3 are made of copper. Copper has good thermal conductivity, which makes it easy for cooling water to enter through the embedded pipe 3 and dissipate heat. The alloy layer 5 is made of 304 stainless steel. The coefficient of thermal expansion of 304 stainless steel is close to that of copper. When heated, it can reduce the cracking problem caused by the difference in the coefficient of thermal expansion of different materials.

[0026] In one specific embodiment, the grooved water jacket body 1 is provided with a threaded sleeve 6. The threaded sleeve 6 is pre-embedded on the water jacket body 1. The material of the threaded sleeve 6 is 304 stainless steel. Since the water jacket body 1 is cast from copper, its weight is between 150kg and 250kg. When the water jacket body 1 is cast, the threaded sleeve 6 is pre-embedded in the water jacket body 1. Later, when installing the water jacket body 1, a lifting ring can be screwed into the threaded sleeve 6 to facilitate the transportation and installation of the water jacket body 1.

[0027] Specifically, the pre-embedded pipe 3 is provided with a distance of 20mm to 30mm from the copper release channel 2 in the middle, and the pre-embedded pipe 3 is provided with a bend 7 in the middle. The bend 7 bends towards the copper release channel 2. The bend 7 allows the pre-embedded pipe 3 to be closer to the outer periphery of the copper release channel 2, thereby improving the cooling capacity of the pre-embedded pipe 3 to the outer periphery of the copper release channel 2 and extending the service life of the water jacket body 1.

[0028] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
