Description

Technical Field

[0001] This utility model belongs to the field of electrode configuration, and specifically relates to a high-performance titanium slag furnace electrode sealing device. Background Technology

[0002] A titanium slag furnace is a key piece of equipment specifically designed for producing high-titanium slag (titanium-rich material with a high TiO2 content). It primarily utilizes a high-temperature electric arc smelting process to separate iron and titanium from titanium-containing ores such as ilmenite (FeTiO2) through reduction smelting, producing high-quality titanium slag as a raw material for subsequent production of titanium dioxide or sponge titanium. In recent years, both domestic and international titanium slag furnace smelting technologies have been developing towards higher efficiency, energy saving, environmental protection, and improved resource recycling to meet market demands and address environmental challenges. Electrode sealing devices are a crucial component of titanium slag furnaces, effectively preventing dust and harmful gas leakage, reducing environmental pollution, and facilitating precise control of the furnace atmosphere and temperature, thereby improving the smelting quality and production efficiency of titanium slag. However, existing titanium slag furnace electrode sealing devices suffer from problems such as poor sealing, current leakage, complex structure, difficult installation and maintenance, and high failure rate. Utility Model Content

[0003] The purpose of this invention is to provide a high-performance electrode sealing device for titanium slag furnaces, which improves upon existing electrode sealing devices by addressing issues such as poor sealing and current leakage.

[0004] Therefore, the present invention adopts the following technical solution: A high-performance titanium slag furnace electrode sealing device includes an electrode holder and a furnace cover. A fixed seat is provided around the electrode holder above the furnace cover. A protective ring is provided on the inner circumference of the fixed seat. A base frame is provided above the fixed seat. A brick ring and a sealing ring are arranged sequentially on the inner circumference of the base frame. An electrode guide frame is provided above the base frame. An upper support is provided above the electrode guide frame. A pressing and fixing cover is provided on the top of the upper support. Insulating flanges are provided between the fixed seat and the base frame, the base frame and the electrode guide frame, and the electrode guide frame and the upper support and are fixed to each other. The inner circumference of the electrode guide frame is provided with a water-cooling jacket and two brass blocks from bottom to top. The brass blocks are equipped with locking devices. A pad is placed between the two brass blocks. Several blocks are evenly distributed around the inner circumference of the upper support.

[0005] Furthermore, the locking device includes a sleeve, a spring, a nut, a baffle, and a screw. One end of the spring is sleeved on a post on the surface of the brass pressure block, and the other end extends into the sleeve and abuts against the baffle. The screw is inserted into the spring. The nut, baffle, and screw are fixed together as one unit. The nut is movably connected to the sleeve through an external thread.

[0006] Furthermore, the press block is filled with aluminum silicate fiberboard.

[0007] Compared with existing technologies, this solution has the following advantages: 1) A total of 4 sealing structures are set along the electrode axis, which effectively prevents dust and flue gas from leaking out of the furnace, avoids pollution to the workshop environment, improves the working conditions of operators, and also reduces heat loss in the furnace and improves the thermal efficiency of the electric furnace.

[0008] 2) The double-layered split brass pressure block with a water-cooled jacket at the bottom not only ensures a tight fit between the brass pressure block and the electrode holder in the circumferential direction to prevent gas leakage in the furnace, but also facilitates the replacement of worn parts. At the same time, the brass pressure block is adjusted by the locking device, which guides the up and down movement of the electrode and ensures the stability and accuracy of the electrode movement.

[0009] 3) This device incorporates multiple layers of insulation between the electrode holder, the furnace cover, and other components to prevent current leakage, significantly improving the normal operation of the electric furnace and the safety of operators. Practical application in multiple titanium slag furnace projects has demonstrated that this significantly improves electrode sealing and also increases production efficiency.

Detailed Implementation

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 and Figure 2As shown, a high-performance titanium slag furnace electrode sealing device includes an electrode holder 16 and a furnace cover 17. A fixing seat 12 is provided around the electrode holder 16 above the furnace cover 17. A protective ring 13 is provided on the inner circumference of the fixing seat 12. A base frame 11 is provided above the fixing seat 12. A brick ring 10 and a sealing ring 9 are arranged sequentially on the inner circumference of the base frame 11. An electrode guide frame 8 is provided above the base frame 11. An upper support 3 is provided above the electrode guide frame 8. A pressing and fixing cover 1 is provided on the top of the upper support 3. Insulating flanges 5 are provided between the fixing seat 12 and the base frame 11, between the base frame 11 and the electrode guide frame 8, and between the electrode guide frame 8 and the upper support 3, and they are fixed to each other. The electrode guide frame 11 has three layers of protection on its inner circumference. From bottom to top, it consists of a water-cooling jacket 15 and two brass blocks 6. A locking device 4 is provided around the brass blocks 6. A pad 7 is provided between the two brass blocks 6. The two brass blocks 6 and the locking device 4 are evenly distributed and independent of each other.

[0016] Several pressure blocks 2 are evenly distributed along the inner circumference of the upper support 3, and the pressure blocks 2 are filled with aluminum silicate fiberboard 14.

[0017] The locking device 4 includes a sleeve 4-1, a spring 4-2, a nut 4-3, a baffle 4-4, and a screw 4-5. One end of the spring 4-2 is fitted onto a post on the surface of the brass pressure block 6, and the other end extends into the sleeve 4-1 and rests against the baffle 4-4. The screw 4-5 is inserted into the spring 4-2. The nut 4-3, the baffle 4-4, and the screw 4-5 are fixed together. The nut 4-3 is movably connected to the sleeve 4-1 through an external thread. During locking adjustment, the sleeve 4-1 is kept stationary, and the nut 4-3 is turned to move the baffle 4-4 to the left, compressing the spring 4-2.

[0018] The sealing ring 9 on the upper part of the base frame 12 provides the first layer of obstruction for the flue gas inside the furnace. The electrode guide frame 8 has three layers. The bottom layer is a water-cooled jacket 15, which uses circulating water to reduce the temperature of the electrode sealing area and extend the material life. The upper two layers are staggered along the circumference with evenly distributed and independent brass pressure blocks 6 and corresponding locking devices 4. When the electrode holder 16 moves horizontally, the brass pressure blocks 6 are adjusted accordingly by the locking devices 4 to correct the electrode deviation and prevent displacement when the electrode rises or falls, thus ensuring the electrode movement. The brass pressure block 6 is tightly attached to the electrode holder 16 by mechanical pressure to prevent gas leakage in the furnace and to provide a second and third layer of protection against the flue gas in the furnace. The brass pressure block 6 plays a role in dynamic sealing and mechanical fixing in this device. Multiple pressure blocks 2 are evenly distributed around the circumference of the upper support 3. Each pressure block 2 is filled with aluminum silicate fiber board 14. Under the action of the locking device 4 and the pressing and fixing cover 1, the aluminum silicate fiber board 14 is tightly attached to the electrode holder 16, forming a fourth line of defense to prevent the flue gas in the furnace from leaking out.

[0019] Insulating flanges 5 are provided between the fixed base 12 and the base frame 11, the base frame 11 and the electrode guide frame 8, and the electrode guide frame 8 and the upper support 3. They are fixed together with bolts, nuts, washers, insulating pads and insulating sleeves to ensure the insulation performance between the electrode holder and the furnace cover and other components, prevent current leakage, avoid electric shock, and ensure the normal operation of the electric furnace and the safety of the operators.

[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model.
