Description

Technical Field

[0001] The utility model relates to the technical field of coal gas recovery devices, in particular to a recycling steelmaking converter coal gas recovery device. Background Art

[0002] Converter steelmaking uses molten iron, scrap steel, and ferroalloys as main raw materials. The steelmaking process is completed in the converter without the help of external energy sources, relying on the physical heat of the molten iron itself and the chemical reactions between the molten iron components to generate heat. Converters are divided into acidic and alkaline types according to the refractory materials, and can be divided into top blowing, bottom blowing, and side blowing according to the position where the gas is blown into the furnace. They are divided into air converters and oxygen converters according to the type of gas. Alkaline oxygen top blowing and top and bottom combined blowing converters are the most commonly used steelmaking equipment due to their fast production speed, large output, high single furnace output, low cost, and low investment. Converters are mainly used for the production of carbon steel, alloy steel, and the smelting of copper and nickel.

A recovery tank 36 is installed on the other end of the third connecting pipe 35, and the recovery tank 36 is installed on the support base 1. When the converter body 2 is in use, the coal gas generated in the converter body 2 is sealed and transferred to the filter box 32 for filtration when it is discharged out, and then fully washed with water through the water washing box 34. Finally, the coal gas after water washing is recovered by using a drainage method and stored in the recovery tank 36 for easy use.

[0025] Reference Figure 2 In the utility model, the impurity removal mechanism includes two filter plates 4, which are installed in the pipe orifice of the second connecting pipe 33, and two fixed blocks 41 are installed on the inner wall of one side of the filter box 32. Guide rods 42 are installed on the two fixed blocks 41. Scrapers 44 are slidably installed on the two guide rods 42, and bristles are installed on one side of the scraper 44. The bristles contact the surface of the filter plate 4, and a return spring 43 is sleeved on the guide rod 42. One end of the return spring 43 is installed on the scraper 44, and the other end of the return spring 43 is installed on the fixed block 41. The driving mechanism includes two bearings 5, which are respectively installed on the inner walls of the filter box 32 on both sides opposite to each other. A rotating shaft 51 is rotatably installed on the two bearings 5, and a plurality of fan blades 52 are equidistantly installed on the rotating shaft 51. The plurality of fan blades 52 are equidistantly installed in an annular manner. The first connecting pipe 3 is adapted, and a transmission plate 53 is installed on the scraper 44. The transmission plate 53 is in contact with the rotating shaft 51, and the wind from the coal gas drives the fan blades 52 to rotate. The fan blades 52 drive the rotating shaft 51 on the bearing 5 to rotate. At the same time, the fan blades 52 will contact the transmission plate 53 when rotating, and then the fan blades 52 in contact with the transmission plate 53 will continuously drive the transmission plate 53 to move upward, and the transmission plate 53 drives the scraper 44 on the guide rod 42 to move. The scraper 44 drives the return spring 43 to stretch and clean the surface of the filter plate 4 on the second connecting pipe 33 from bottom to top. After the fan blade 52 rotates to the highest point and disengages from the transmission plate 53, the restoring force of the return spring 43 is used to drive the scraper 44 to move downward to clean the filter plate 4 from top to bottom, so that the dust accumulated on the surface of the filter plate 4 can be cleaned through reciprocating motion.

[0026] Reference Figure 3In the present invention, the dust collection mechanism includes a mounting groove 6, a mounting groove 6 is provided on the inner wall of the bottom side of the filter box 32, a dust drawer 61 is slidably installed on the inner wall of the mounting groove 6, a limiting groove 62 is provided on the outer surface of the filter box 32, a retaining rod 63 is installed on the inner wall of the limiting groove 62, a T-shaped locking plate 65 is slidably installed on the retaining rod 63, the bottom side of the T-shaped locking plate 65 contacts the dust drawer 61, a locking spring 64 is sleeved on the retaining rod 63, and one end of the locking spring 64 is installed It is installed on the top inner wall of the limiting groove 62, and the other end of the locking spring 64 is installed on the upper surface of the T-shaped locking plate 65. After the converter body 2 stops working, the dust in the filter box 32 will gather and fall into the dust drawer 61. At this time, the dust drawer 61 only needs to lift up the T-shaped locking plate 65 on the retaining rod 63 so that the bottom end of the T-shaped locking plate 65 loses its restraint on the outer surface of the dust drawer 61, so that the dust drawer 61 can be easily pulled out of the filter box 32 for dust cleaning.

[0027] The working principle is as follows: when the converter body 2 on the support seat 1 is used for steelmaking, in order to facilitate the recovery and use of the coal gas generated by the converter body 2 during steelmaking, the coal gas generated in the converter body 2 is discharged to the outside, and the first connecting pipe 3 is used to discharge the coal gas into the filter box 32 on the support leg 31 for filtration. At the same time, the wind from the coal gas drives the fan blades 52 to rotate, and the fan blades 52 drive the rotating shaft 51 on the bearing 5 to rotate. At the same time, the fan blades 52 will contact the transmission plate 53 when rotating, and then the fan blades 52 in contact with the transmission plate 53 will continuously drive the transmission plate 53 to move upward, and the transmission plate 53 drives the scraper 44 on the guide rod 42 to move, and the scraper 44 drives the return spring 43 to stretch and clean the surface of the filter plate 4 on the second connecting pipe 33 from bottom to top. After the fan blades 52 rotate to the highest point and disengage from the transmission plate 53, the restoring force of the return spring 43 is used to bring The movable scraper 44 moves downward to clean the filter plate 4 from top to bottom, thereby cleaning the dust accumulated on the surface of the filter plate 4 through reciprocating motion, and the coarsely filtered coal gas is discharged into the water washing box 34 through the second connecting pipe 33. Since the pipe mouth of the third connecting pipe 35 is higher than the pipe mouth of the second connecting pipe 33, it is fully washed with water. Then, the fully washed coal gas will be discharged into the recovery tank 36 through the third connecting pipe 35, and the clean coal gas will be collected in the recovery tank 36 by the drainage method for easy use. At the same time, after the converter body 2 stops working, the dust in the filter box 32 will accumulate and fall into the dust drawer 61. At this time, the dust drawer 61 only needs to lift the T-shaped locking plate 65 on the retaining rod 63 upward, so that the bottom end of the T-shaped locking plate 65 loses the restraint on the outer surface of the dust drawer 61, so that the dust drawer 61 can be conveniently pulled out of the filter box 32 for dust cleaning.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
