By setting up the scraping module 325, the main shaft 3251 drives the turntable 3252 to rotate under the drive of the transmission structure 324, and simultaneously drives the push column 3253 to rotate in the connecting hole 3256 in the connecting plate 3254, thereby pushing the front end of the connecting plate 3254 to move, and at the same time making the rear end of the connecting plate 3254 swing back and forth with the connection with the connecting shaft 326 as the fulcrum, so that the scraper 3257 can be driven to periodically scrape off the dust attached to the arc filter 321, so that the dust falls into the ash hopper connected to the bottom of the fixed shell 31, thereby ensuring the filtering performance of the arc filter 321.

[0054] Brief description of the use process: The high-temperature exhaust gas generated by the steel rod gas heating furnace 1 enters the interior of the fixed shell 31 through its own exhaust pipe, and the high-temperature exhaust gas passes through the arc filter 321 for primary dust removal, and then passes through the support tube 322 to the dust bag 34 for secondary dust removal. The treated high-temperature exhaust gas enters the heat exchange component 4 through the intake pipe 5 for heat exchange, and at the same time drives the blade 327 and the connecting shaft 326 to rotate under the flow of the exhaust gas, and synchronously drives the top and bottom spindles through the transmission structure 324 3251 rotates, so that the main shaft 3251 drives the turntable 3252 to rotate, and synchronously drives the connection hole 3256 of the push column 3253 in the connecting plate 3254 to rotate, thereby pushing the front end of the connecting plate 3254 to move, and at the same time making the rear end of the connecting plate 3254 reciprocate with the connection with the connecting shaft 326 as a fulcrum, thereby driving the scraper 3257 to periodically scrape off the dust attached to the arc filter 321, so that the dust falls into the ash hopper connected to the bottom of the fixed shell 31, and the dust is collected and processed centrally.

[0055] like Figure 8 As shown, the present invention also provides a method for using a steel bar processing device with an energy recovery structure, comprising the following steps:

[0056] S1. The steel bar is heated by the steel bar gas heating furnace 1, and the exhaust gas generated during the heating process enters the exhaust gas treatment component 3 through the exhaust port of the steel bar gas heating furnace 1 for pretreatment;

[0057] S2. The high-temperature exhaust gas entering the exhaust gas treatment component 3 first passes through the primary dust removal component 32 to remove large dust particles contained in the high-temperature exhaust gas. After passing through the primary dust removal component 32, the high-temperature exhaust gas passes through the dust removal bag 34 to remove smaller dust particles;

[0058] S3. The treated high-temperature exhaust gas enters the heat exchange component 4 through the air intake pipe 5, so that heat energy is exchanged between the high-temperature exhaust gas and the cold fluid flowing in the heat exchange component 4 to achieve the purpose of energy recovery.
