[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0023] like Figure 1-2 As shown, this application provides a novel flash furnace frame water jacket, comprising a frame water jacket 1, a furnace wall water jacket 3, and a furnace wall refractory brick 4. A pair of embedded copper pipes 2 are installed inside the frame water jacket 1, and the interior of the frame water jacket 1 is hollow. The pair of embedded copper pipes 2 surround the inner cavity of the frame water jacket 1. The frame water jacket 1 passes through the furnace wall refractory brick 4. The furnace wall water jacket 3 is installed at the outer end of the frame water jacket 1 and can be fixed to the frame water jacket 1 by welding. The furnace wall water jacket 3 abuts against the furnace wall refractory brick 4.

[0024] Flash grate copper slag removal refers to a process carried out in a flash furnace, in which copper ore is smelted and waste slag is discharged through slag removal. The following is the specific workflow of flash grate copper slag removal:

[0025] Copper ore processing: First, the copper ore is fed into a flash furnace for smelting. In this process, the copper ore is usually heated to a high temperature along with other substances in order to extract the copper from the ore.

[0026] Combustion and smelting: In a flash furnace, ore and other raw materials are heated and burned to form molten metal and slag.

[0027] Slag removal process: During copper smelting, the waste slag in the furnace needs to be removed regularly to maintain the normal operation of the furnace.

[0028] The slag removal process typically involves the following steps:

[0029] Waste collection: In a flash furnace, waste is formed inside the furnace and periodically collected to a specific area.

[0030] Slag removal device: Flash furnaces are usually equipped with a special slag removal device to remove accumulated slag from the furnace.

[0031] Waste residue treatment: Once the waste residue is discharged from the furnace, it will be further processed or treated to recover potentially valuable components, while the remaining waste residue will be disposed of or reused.

[0032] Circular smelting: Flash furnaces typically employ a circular smelting method, which involves continuously adding new raw materials and removing waste slag to keep the smelting process running, thereby improving smelting efficiency and reducing production costs.

[0033] To ensure cooling efficiency and furnace safety during copper slag discharge in the flash grate, a frame water jacket is installed at the copper slag outlet of the flash furnace. The frame water jacket penetrates the side wall of the settling tank. Copper slag discharge in the flash grate is intermittent. Each discharge requires the use of an oxygen blowing pipe to burn the opening. If the burning opening is misaligned, it will damage the frame water jacket. In severe cases, it will cause the frame water jacket to leak, making it impossible to discharge at the outlet.

[0034] In this design, the furnace wall refractory bricks 4 are connected to the flash furnace body. These refractory bricks are high-temperature resistant and used to construct the furnace wall structure. Their main function is to resist high temperatures and thermal stress, protecting the furnace wall from the erosion of high-temperature gases and materials inside the furnace, while maintaining the stability of the high-temperature environment inside the furnace. The frame water jacket 1 extends through the furnace wall refractory bricks 4 into the furnace body. The frame water jacket 1 is a cooling device that uses water circulation to cool the slag discharge port area, preventing overheating and extending the equipment's service life. The furnace wall water jacket 3 is also a cooling device, simultaneously cooling both the furnace wall refractory bricks 4 and the frame water jacket 1. Compared to existing frame water jackets, the frame water jacket 1 in this design is specially equipped with two embedded copper pipes 2. Water is circulated through these embedded copper pipes 2 for cooling, circulating the cold water around the inner cavity of the frame water jacket 1 to absorb its heat. This reduces the temperature of the frame water jacket 1 and its slag discharge port, preventing overheating and extending the service life of the equipment. Through water circulation, the frame water jacket 1 effectively protects the equipment components around the furnace slag discharge port from high temperatures. Continuous cooling prevents damage or overheating of equipment components, ensuring normal operation of the equipment. The slag discharge port on the frame water jacket 1 is blocked with clay balls. When copper or slag needs to be discharged, the clay balls are removed, and oxygen and iron pipes are used to melt and heat the cold copper in the copper discharge channel into the furnace before copper discharge. After copper discharge is completed, the clay balls are used to seal the port. The slag discharge operation is similar. The two embedded copper pipes 2 provide greater cooling intensity and better cooling effect. Even if the frame water jacket 1 is damaged and leaks, at least one water pipe can still be used for cooling, thus ensuring normal copper and slag discharge operations at the discharge port and ensuring normal production of the flash furnace.

[0035] like Figure 3-4 As shown, the interior of the frame water jacket 1 is provided with frame water jacket inner bricks 5, the shape of the frame water jacket inner bricks 5 matches the shape of the inner cavity of the frame water jacket 1, a through hole 6 is opened at the center of the frame water jacket inner bricks 5, a slag discharge port is opened at one end of the frame water jacket 1, the slag discharge port is connected to the inner cavity of the frame water jacket 1, the inner diameter of the through hole 6 is the same as that of the slag discharge port, and the through hole 6 is coaxially arranged with the slag discharge port. The cross-sectional shape of the furnace wall water jacket 3 matches that of the furnace wall refractory bricks 4.

[0036] When copper and slag need to be discharged, the copper slag can be discharged through the through hole 6 and the slag discharge port in sequence. The setting of the inner brick 5 of the frame water jacket can help reduce the heat conduction inside the furnace body, reduce heat loss, and improve energy utilization efficiency. At the same time, it can reduce the degree of high temperature erosion of the frame water jacket 1 and extend the service life of the frame water jacket 1. The inner diameter of the through hole 6 is the same as that of the slag discharge port, and the through hole 6 and the slag discharge port are set coaxially to ensure the connection between the through hole 6 and the slag discharge port, and prevent copper slag from being trapped on the inner wall of the through hole 6 or the slag discharge port.

[0037] Working principle:

[0038] In use, the furnace wall refractory bricks 4 are connected to the flash furnace body. Their main function is to resist high temperatures and thermal stress, protecting the furnace wall from corrosion by high-temperature gases and materials inside the furnace. The frame water jacket 1 extends through the furnace wall refractory bricks 4 into the furnace body. Its function is to cool the slag discharge port area through water circulation, preventing overheating in the slag discharge port area. The furnace wall water jacket 3 is also a cooling device, which can simultaneously cool the furnace wall refractory bricks 4 and the frame water jacket 1. The frame water jacket 1 has two embedded copper pipes 2 specially installed inside. Water is circulated through the embedded copper pipes 2 for cooling, and the cold water circulates through the inner cavity of the frame water jacket 1. The surrounding area absorbs heat from the frame water jacket 1, thereby reducing the temperature of the frame water jacket 1 and its slag discharge port. The slag discharge port on the frame water jacket 1 is blocked with clay balls. When copper or slag needs to be discharged, the clay balls are cleaned off, and the cold copper in the copper discharge channel is melted and heated into the furnace using oxygen and iron pipes before copper is discharged. After copper discharge is completed, the clay balls are used to seal the port. The slag discharge operation is similar. The setting of two embedded copper pipes 2 ensures that even if the frame water jacket 1 is damaged and leaks, at least one water pipe can still be used for cooling, thereby ensuring the normal copper and slag discharge operation at the discharge port and ensuring the normal production of the flash furnace.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
