Description

Technical Field

[0001] The invention relates to the technical field of electric furnace circulation equipment, in particular to a closed high-titanium slag electric furnace with a waste heat circulation structure. Background Art

[0002] The closed high-titanium slag electric furnace is a key equipment used in the metallurgical industry to produce high-titanium slag. It adopts a closed design, which can effectively reduce heat loss and harmful gas emissions. Electric energy is input into the furnace through electrodes to generate high temperature, causing titanium-containing furnace charges to undergo reduction smelting reactions in the furnace, converting raw materials such as titanium concentrate into high-titanium slag. This electric furnace has the characteristics of high efficiency and environmental protection, which helps to improve the production quality and efficiency of high-titanium slag.

[0003] The Chinese patent with the announcement number CN219934635U discloses a closed high-titanium slag electric furnace with a waste heat circulation structure. The excessive area of the flue gas entering the electric furnace body is enlarged through the sedimentation bin, the flow rate of the flue gas is slowed down, and the larger particles in the flue gas fall into the groove of the adsorption bottom plate under the influence of their own gravity. The filter plate of the suction hood further filters the particles in the flue gas, and the flue gas enters the suction pipe through the suction duct and is accelerated to enter the heat exchange box. The heat exchange box can heat the flue gas through heat conduction, and the drying frame allows the still hot gas to preheat the raw materials to be fired, thereby improving the utilization efficiency of the waste heat of the electric furnace flue gas; however, the above It is difficult to disassemble and replace the filter when the device is in use. The filter plate will continuously intercept impurities in the gas during use. Over time, the impurities will gradually accumulate on the filter plate, and the pores of the filter plate will be blocked, resulting in a significant drop in filtration efficiency. After the gas containing more impurities enters the heat transfer box, the impurities may adhere to components such as the heat transfer pipe, affecting the heat exchange efficiency, and may also accelerate the wear and corrosion of components. At the same time, when the filter plate needs to be replaced, due to the difficulty of disassembly, it may take a longer downtime to complete the replacement work, which will reduce the operating time of the electric furnace, affect the production output of high-titanium slag, and reduce the company's production efficiency and economic benefits.

[0047] The overall working principle of the present invention is:

[0048] The electric furnace body 4 generates high-temperature gas during operation. These gases enter the processing box 5 through the pipe body connecting the top of the electric furnace body 4 and the processing box 5. The gas entering the processing box 5 passes through the filter plate 9. The filter plate 9 can filter out impurities in the gas, ensuring that the gas entering the heat conduction box 7 and the gas storage tank 8 later is relatively pure, reducing damage to the equipment. The filter plate 9 is fixed in the processing box 5 by a positioning component. In the positioning component, when the filter plate 9 needs to be replaced, the two positioning plates 211 on the top of the filter plate 9 extend to the top of the processing box 5, and the control handle on the rotating disk 219 is rotated to drive the gear 216 to rotate. Since the gear 216 is engaged with the rack plate 217, the rack plate 217 moves in the fixed groove, and the limit bars on both sides of the rack plate 217 are in the limit groove. The rack plate 217 drives the movable plate 213 to move in the movable groove of the extension seat 214 through the linkage block, so that the two plug plates 218 on one side of the movable plate 213 are separated from the sockets of the positioning plate 211, thereby canceling the positioning of the filter plate 9 in the processing box 5, and the control handle on the rotating disk 219 is rotated in the opposite direction to pull the plug plate 218 out of the sockets of the positioning plate 211, and start the electric push rod 22 inside the base 1. The telescopic end of the electric push rod 22 drives the linkage plate 29 and the reinforcement plate 210 to descend, and the telescopic column 23 slides downward in the storage seat 21, and the receiving seat 24 descends accordingly. The processing box 5 moves downward due to its own gravity through the descent of the receiving seat 24, and the two fixed plates are driven by the downward movement of the processing box 5. 26 is moved downward, and the two fixing plates 26 are moved downward to drive the limit plate and the support plate 25 to be plugged in, so that the treatment box 5 can be effectively supported. The receiving seat 24 is moved downward to drive the vertical plate 28 to move downward. Subsequently, the screw bolts 27 are screwed to separate the receiving plate 215 from the opening groove, and the bottom plate 212 is pulled to separate the top from the plug rod, so that the filtered dirt can be discharged. Finally, the filter plate 9 is pulled to drive the two positioning plates 211 to be separated from the treatment box 5, so as to realize the removal of the filter plate 9, and it can be installed in the same way. The water in the water tank 31 is injected through the water injection pipe, and the water supply pump 36 pumps the water in the water tank 31 into the water supply pipe 34. The water supply pipe 34 transports the water to the heat conduction box 7 and the top of the treatment box 5. The guide pipe 6 on one side introduces the filtered gas into the heat conduction box 7. The gas flows in the heat conduction box 7 through the universal ball 12 and the heat conduction pipe 13, exchanges heat with the water in the heat conduction box 7, and transfers heat to the water in the water tank 31 to realize waste heat recovery. The water after absorbing heat is discharged through the drain pipe 14. At the same time, when the water inside the heat conduction box 7 needs to be circulated, the circulation pipe 35 is opened through the one-way valve, and the drain pipe 14 is closed. The circulation pipe 35 is used to transport the water to the condenser 33 for cooling. The cooled water returns to the water tank 31 to realize water recycling. In addition, it can also realize rapid heat exchange of the heat conduction pipe 13. The one-way valve inside the drain pipe 14 and the circulation pipe 35 ensures the one-way flow of water, ensuring the normal operation of the circulation system.After the waste heat is recovered from the heat transfer box 7, the gas enters the gas storage tank 8 through the connecting pipe 11 and the gas transmission pipe 10 for storage. The gas storage tank 8 can discharge the gas through the exhaust pipe for subsequent use. During operation, the main functions of the process are to treat the heat-generated gas from the high-titanium slag smelting, recover the waste heat, and easily replace the filter plate 9. The high-temperature gas generated by the electric furnace body 4 is first filtered through the treatment box 5 to remove impurities before entering the heat transfer box 7 for waste heat recovery. Finally, the treated gas is stored in the gas storage tank 8, and the filter plate 9 can be easily disassembled and replaced through the disassembly and assembly mechanism 2.

The two heat conduction tubes (13) are both located inside the heat conduction box (7), and the two heat conduction tubes (13) extend to one side of the heat conduction box (7) and are commonly connected to a connecting tube (11). The outer walls of both sides of the connecting tube (11) are fixed with reinforcement sleeves (15), and the reinforcement sleeves (15) are fixed to the extension plate (16). One side of the gas storage tank (8) is connected to an exhaust pipe, and the bottom of the connecting tube (11) is connected to an air supply pipe (10), and the air supply pipe (10) is connected to the gas storage tank (8).
