Description

Technical Field

[0001] This utility model relates to the field of copper smelting technology in the non-ferrous metals industry, specifically to a novel brick-mounted water jacket for the rising flue of a silver furnace. Background Technology

[0002] Baiyin Nonferrous Metals Group Co., Ltd.'s "Baiyin Copper Refining Method" is my country's only original double-sided blowing pool smelting process with independent intellectual property rights. After continuous exploration and improvement, it has achieved the current crude copper production capacity of 200kt / a and corresponding technical conditions. In 2021, Baiyin Nonferrous Metals Group Co., Ltd. carried out a technological innovation and upgrade project for the Baiyin furnace, and built a new type of Baiyin furnace. The new Baiyin furnace's rising flue (dimensions: 4000*2400mm) is located above the partition wall passage, and the dust-laden flue gas generated by the smelting reaction enters the waste heat boiler and subsequent processes through the rising flue.

[0003] The original design of the inlet of the new type of silver furnace's rising flue was a plain plate water-cooled jacket. During the silver furnace's production process, molten dust particles in the flue gas adhered to the water-cooled jacket. After being cooled by the jacket, the adhering material fell into the molten pool, causing the melt in the blowing zone to become sticky, deteriorating the furnace condition, and in severe cases, causing blockage of the partition wall passage, which in turn led to reduced production load or even shutdown of the silver furnace. To solve this problem, during the technical renovation of the silver furnace in 2023, the water jackets on the north, east, and west sides of the rising flue were removed and replaced with refractory bricks. A new type of brick-hanging water jacket for the rising flue of the silver furnace was designed on the south side. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of brick-hanging water jacket for the rising flue of a silver furnace. By embedding high-temperature resistant bricks into the water jacket, it effectively prevents the adhesive from falling off and improves production stability.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A novel brick-hanging water jacket for the rising flue of a silver furnace includes a brick-hanging water jacket body 1. The brick-hanging surface of the brick-hanging water jacket body 1 is divided into four refractory brick embedding grooves 3 by a cross-shaped dividing structure 2 inside it. The brick-hanging water jacket body 1 has a built-in copper cooling circulating water pipe 4.

[0007] The refractory brick is embedded in the groove 3. The lower side of the brick support surface is provided with a brick-holding arc groove with a radius of 15mm.

[0008] The length of the brick-hanging water jacket body 1 is 1760mm, the height is 1100mm, and the thickness is 400mm. The depth of the refractory brick embedded in the groove 3 is 300mm.

[0009] The copper cooling circulating water pipe 4 has four sets. The inlet and outlet ports of each set of copper cooling circulating water pipes are located on the back side opposite the brick hanging surface of the brick hanging water jacket body 1. The upper part of the back side opposite the brick hanging surface of the brick hanging water jacket body 1 is also provided with a lifting lug.

[0010] The brick-hanging water jacket body 1 consists of three pieces, and adjacent brick-hanging water jacket bodies 1 are connected by a snap fastener.

[0011] The brick-hanging water jacket body 1 is made of cathode copper.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. This utility model effectively solves the problem of the original water-cooled jacket soot adhering material falling off, avoids the situation of the melt in the molten pool becoming sticky and the furnace condition deteriorating, and significantly improves the production stability of the silver furnace.

[0014] 2. This utility model reduces the amount of adhesive falling off, solves the problem of reduced production load and shutdown of the silver furnace caused by adhesive blocking the partition wall channel, and improves the annual operating rate of the silver furnace.
