Abstract
Description
Technical Field
[0001] This invention belongs to the field of flue gas treatment technology and relates to a converter flue gas treatment device. Background Technology
[0002] During industrial production, converters emit large amounts of flue gas containing dust and particulate matter. Direct emission of this flue gas can cause serious environmental pollution and also harm human health.
[0003] Existing converter flue gas treatment devices mostly employ a single filter structure, which is prone to clogging by large particles of impurities on the filter surface during long-term use. This clogging leads to a decrease in flue gas flow efficiency and reduces the overall filtration effect of the treatment device.
[0004] Traditional methods for solving clogging problems require frequent shutdowns to disassemble and replace filter components for cleaning or replacement. This not only increases labor maintenance costs but also affects the continuity of industrial production.
[0005] Meanwhile, some cleaning structures are prone to leaving impurities or causing secondary pollution when cleaning impurities, which further reduces the reliability of flue gas treatment. Summary of the Invention
[0006] The purpose of this invention is to solve the above-mentioned problems and provide a converter flue gas treatment device.
[0007] To achieve the above objectives, the present invention provides a converter flue gas treatment device, including a filter chamber, one end of which is closed and a first motor is provided on its outer side. The rotating shaft of the first motor extends into the filter chamber and is fixedly connected to a filter cylinder. The surface of the filter cylinder is provided with filter holes, and a cleaning roller is also provided on the rotating shaft. The cleaning roller is located on the outer side of the filter cylinder. The first motor drives the filter cylinder and the cleaning roller to rotate. An annular cleaning structure is provided on the outer periphery of the filter cylinder. The annular cleaning structure is connected to a motor lead screw pair, and the motor lead screw pair drives the annular cleaning structure to move axially along the filter cylinder.
[0008] Furthermore, the filter chamber is provided with an air inlet and a waste outlet, with the waste outlet located below the cleaning roller.
[0009] Furthermore, a discharge section is provided at one end of the filter cartridge.
[0010] Furthermore, the annular cleaning structure is provided with a first connecting seat and a second connecting seat, the first connecting seat having a threaded hole and the second connecting seat having a through hole; The motor lead screw assembly includes a lead screw that mates with a threaded hole. One end of the lead screw is rotatably connected to the inner wall of the filter chamber, and the other end extends into the outside of the filter chamber and is connected to a second motor. A guide rod is provided at the through hole, and the two ends of the guide rod are fixedly connected to the inner wall of the filter chamber.
[0011] Furthermore, the annular cleaning structure has bristles, and the cleaning roller has cleaning roller teeth.
[0012] Furthermore, the contact pressure between the bristles and the outer surface of the filter cartridge is 1-2 N / cm².
[0013] The beneficial effects of this invention are as follows: This device uses a first motor to drive the filter cartridge and cleaning roller to rotate synchronously, while the motor's lead screw drives the annular cleaning structure to move axially along the filter cartridge. The bristles of the annular cleaning structure can continuously clean the impurities trapped on the outer surface of the filter cartridge, effectively preventing filter pore blockage, ensuring smooth flue gas flow, and maintaining stable filtration efficiency.
[0014] When the annular cleaning structure moves to the cleaning roller position, the roller teeth can reverse the cleaning action on the bristles, shaking off impurities attached to the bristles. The shaken-off impurities can be discharged through the discharge port, achieving self-cleaning of the cleaning structure. This design reduces the frequency of manual disassembly and cleaning, extends the maintenance cycle of the device, and significantly reduces maintenance costs.
[0015] The device features highly integrated components and a compact structure, making it adaptable to various conversion furnace flue gas treatment scenarios. The filtered flue gas can be discharged and recycled through the exhaust section, achieving resource recovery and meeting the demands of energy-saving and environmentally friendly industrial development.

[0019] Combination Figures 1-6 As shown, the present invention provides a converter flue gas treatment device, including a filter chamber 1, one end of the filter chamber 1 is closed and a first motor 2 is provided on the outside, the shaft 3 of the first motor 2 extends into the filter chamber 1 and is fixedly connected to a filter cylinder 4, and the surface of the filter cylinder 4 is provided with filter holes 41.
[0020] In this embodiment, the filter chamber 1 is provided with an air inlet 11 and a waste outlet 12. The flue gas from the converter enters the filter chamber 1 through the air inlet 11, and then enters the filter cylinder 4 through the filter holes 41. Large particulate impurities are trapped outside the filter cylinder 4. The filter chamber 1 has a discharge section 42, and the filtered flue gas is discharged from the discharge section 42 for recycling.
[0021] According to one embodiment of the present invention, a cleaning roller 5 is also provided on the rotating shaft 3. The cleaning roller 5 is located outside the filter cylinder 4, and the impurity discharge port 12 is located below the cleaning roller 5.

The annular cleaning structure 6 is connected to a motor lead screw pair 7. The motor lead screw pair 7 drives the annular cleaning structure 6 to move axially along the filter cylinder 4 and can move to the cleaning roller 5. The cleaning roller 5 has cleaning roller teeth 51, which can clean the bristles 63. Specifically, the annular cleaning structure 6 is provided with a first connecting seat 7 and a second connecting seat 62. The first connecting seat 61 has a threaded hole. The motor lead screw pair 7 includes a lead screw 71 that cooperates with the threaded hole.

Large particles of impurities are trapped outside the filter cylinder 4, and the water entering the filter cylinder 4 enters the vertical cylinder 1 for further filtration. The annular cleaning structure 6 can periodically move axially along the outer surface of the filter cylinder 4 under the action of the motor screw pair 7 to clean the trapped impurities on the outer surface of the filter cylinder 4. When the annular cleaning structure 6 moves to the cleaning roller 5, the cleaning roller 5 can clean the annular cleaning structure 6. In addition, when the annular cleaning structure 6 moves to clean, the first motor 2 drives the filter cylinder 4 and the cleaning roller 5 to rotate, thereby effectively improving the cleaning effect of the annular cleaning structure 6 on the filter cylinder 4 and the cleaning effect of the cleaning roller 5 on the annular cleaning structure 6.
