[0036] like Figure 1 - Figure 8As shown, the left and right two output ends of the bidirectional motor 10 are fixedly connected with second rotating rods 17, the other ends of the two second rotating rods 17 are fixedly connected with eccentric wheels 18, the second rotating rods 17 on the two output ends of the bidirectional motor 10 are connected with the eccentric wheels 18, and the eccentric wheels 18 are driven to rotate, the outer side walls of the two eccentric wheels 18 are fixedly connected with supporting rods 19, and the other sides of the two supporting rods 19 are fixedly connected to the left and right two ends of the second connecting rod 16.

[0038] It should be noted that the utility model discloses a side-blown furnace convenient for processing scum, first, the driving motor 301, bidirectional motor 10, flow valve 4 and control panel 8 are connected with the external power supply to supply power to the device.

[0039] When the driving motor 301 is started, the output end of the motor starts to rotate, and the power output is transmitted through the first rotating rod 302 fixedly connected with the output end, when the first rotating rod 302 rotates under the driving of the driving motor 301, the first connecting ring 304 will do the circular motion with the first rotating rod 302, and further drive the stirring rod 305 to stir. The stirring rod 305 stirs in the inside of the furnace body 1 and the upper side wall area of the first flow guide plate 2, and through stirring, the materials in the furnace can be mixed more uniformly, the materials are prevented from depositing or being locally overheated, and the scum is uniformly distributed in the molten pool, which is convenient for subsequent scum processing.

[0040] Meanwhile, the first rotating rod 302 rotates, and the first bevel gear 307 fixed to the outer side of the first rotating rod 302 also rotates. Due to the meshing relationship between the first bevel gear 307 and the two second bevel gears 308, the rotation of the first bevel gear 307 drives the two second bevel gears 308 to rotate, thereby realizing the conversion of the power direction. When the second bevel gear 308 rotates under the drive of the first bevel gear 307, the first connecting rod 309 fixedly connected with the second bevel gear 308 rotates, thereby driving the second connecting ring 310 and the stirring blade 311 to rotate and stir. The stirring action of the stirring blade 311 is combined with the stirring action of the stirring rod 305, which further enhances the stirring effect of the materials in the furnace, makes the material mixing more sufficient, the temperature distribution more uniform, and can promote the slag to be better layered with the metal liquid, which is beneficial to the removal of the slag.

[0041] The inside of the furnace body 1 is provided with a filter plate 12, and the left and right sides of the filter plate 12 and the bottom wall of the first flow guide plate 2 are fixedly connected with connecting blocks 13. The front side wall of every two connecting blocks 13 is fixedly connected with spring sheets 14. The spring sheets 14 provide elastic support for the filter plate 12, and the elastic support structure enables the filter plate 12 to have certain buffering and self-adaptive capacity when subjected to certain external force. Meanwhile, the connecting blocks 13 connect the filter plate 12 with the surrounding structure, thereby ensuring the relative position stability of the filter plate 12 inside the furnace body 1.

[0042] The left and right two output ends of the bidirectional motor 10 are fixedly connected with second rotating rods 17. After the bidirectional motor 10 is started, power is transmitted through the two second rotating rods 17. The other ends of the two second rotating rods 17 are fixedly connected with eccentric wheels 18, the eccentric wheels 18 rotate with the rotation of the second rotating rods 17, the outer side walls of the eccentric wheels 18 are fixedly connected with supporting rods 19, and the other sides of the two supporting rods 19 are fixedly connected to the left and right ends of the second connecting rod 16. The supporting rods 19 make reciprocating motion with the rotation of the eccentric wheels 18, thereby driving the second connecting rod 16 to make reciprocating motion. Since the second connecting rod 16 is connected with the semicircular block 15 at the front end of the filter plate 12, the filter plate 12 makes reciprocating motion in the up-down or front-back direction under the drive of the second connecting rod 16, thereby achieving the effect of vibration and shaking to filter the metal.
