[0028] Please refer to Figure 1-7, the present utility model provides a technical solution for a through-type sword and knife forging heating furnace. A through-type sword and knife forging heating furnace includes a heating furnace body 1. A purification box 2 and a support plate 23 are fixed on the side of the heating furnace body 1.

Through the setting of the purification mechanism, the purification mechanism can filter and purify the tail gas in the heating furnace body. The tail gas after purification and waste heat recovery is discharged through the exhaust pipe 29, so as to reduce the pollution of the tail gas to the surrounding environment.

[0029] Refer to Figure 2 , Figure 3 and Figure 4, the replacement mechanism includes a first motor 9 fixed to the inner bottom of the dust-proof housing 24. A small gear 10 is provided at the output end of the first motor 9. A large gear 11 is meshed on the side of the small gear 10. The bottom end of the large gear 11 rotates in the dust-proof housing 24 through a support rod. A rotating disk 12 is provided in the middle of the top end of the large gear 11. Six rotating shafts 13 are evenly provided on the outer surface of the rotating disk 12 in the circumferential direction. An annular plate 14 is provided at the end of the rotating shaft 13.

The replacement mechanism can quickly replace the filter screen 6. After the filter screen 6 is quickly replaced, the continuous use can be not affected, so that the idle time of the entire purification mechanism can be reduced, and the practicability of the entire device can be improved.

[0030] Refer to Figure 5 , Figure 6 and Figure 7, the pushing component includes a motor support frame 25 fixed to the inner wall on one side of the annular hole 15 and an annular groove opened on the inner wall on the other side of the annular hole 15. A second motor is provided at the top of the motor support frame 25, and a driving gear 16 is provided at the output end of the second motor. A plurality of sliders 26 are rotatably connected in the annular groove. An annular rotating block 17 is fixed to the side of the plurality of sliders 26. A plurality of engaging teeth are uniformly provided on the outer wall of the annular rotating block 17. The driving gear 16 meshes with the engaging teeth. The pushing component further includes a plurality of first inclined blocks 18 uniformly fixed to the upper and lower ends of the annular rotating block 17. A connecting ring 20 is slidably connected to the upper and lower sides of the annular rotating block 17 in the annular hole 15. A plurality of second inclined blocks 19 are provided at one end of the connecting ring 20 close to the first inclined block 18. The inclined ends of the second inclined block 19 and the first inclined block 18 are pressed against each other. The end of the connecting ring 20 away from the second inclined block 19 is connected to the sealing plate 21. The sealing plate 21 is of an annular structure. A plurality of springs 22 are provided between the connecting ring 20 and the inner wall of the annular hole 15. Through the setting of the pushing component, the pushing component is arranged in the annular hole 15 in the annular plate 14. Before the filter screen 6 rotates and is replaced, the pushing component can drive the sealing plates 21 at the upper and lower ends of the annular plate 14 to be retracted into the annular hole 15, so that there will be no resistance when the filter screen 6 rotates out of the purification box 2, and after the filter screen is replaced, the driving pushing component can push the sealing plates 21 at the upper and lower ends to move out of the annular hole 15 and be clamped into the groove 8, so as to fill the gap between the through hole 7 and the annular plate 14.

[0031] Refer to Figure 2 , the tooth ratio of the large gear 11 is six times that of the small gear 10. When the small gear 10 rotates one circle, the large gear 11 rotates one-sixth of a circle, just rotating the next brand-new filter screen 6 into the purification box 2.

[0032] When in use, a pressure sensor and a processor are fixedly connected to the top of the heating furnace body 1. The pressure sensor is signal-connected to the processor, and the processor is signal-connected to the air pump 3. The pressure sensor monitors the air pressure inside the heating furnace body 1 and transmits the pressure information to the processor. The processor adjusts the output power of the air pump 3 according to the pressure change of the heating furnace body 1, saving energy and protecting the heating furnace body 1. That is, the air pump 3 is started, and the tail gas inside the heating furnace body 1 is pumped out through the first suction pipe 4 to reduce the pressure inside the heating furnace body 1. Then, the tail gas is transported to the bottom of the filter screen 6 through the second suction pipe 5. The tail gas is pressed to flow upward, and after being double-filtered by the filter screen 6 and the activated carbon adsorption plate, it enters the top of the activated carbon adsorption plate. The tail gas filtered and purified at the top of the activated carbon adsorption plate is pressed and enters the inside of the purification chamber through the ventilation pipe 28 to heat the tap water inside the purification chamber. The tail gas after purification and waste heat recovery is discharged through the exhaust pipe 29, thus reducing the pollution of the tail gas to the surrounding environment;

[0033] When the filter screen 6 inside the purification box 2 has been used for a period of time and accumulates a large amount of impurities, the replacement mechanism can be activated to replace the filter screen 6 with a brand-new one for use inside the purification box 2. Before activating the replacement mechanism, first drive the sealing plate 21 on the surrounding annular plate 14 of the filter screen 6 inside the purification box 2 to retract from the groove 8 into the annular hole 15, so that there will be no resistance when the filter screen 6 rotates out of the purification box 2. That is, start the second motor, and the second motor rotates to drive the driving gear 16 to rotate. The driving gear 16 drives the engaging teeth engaged with it to rotate. The engaging teeth rotate to drive the annular rotating block 17 and the inclined blocks 18 at the upper and lower ends of the annular rotating block 17 to rotate. At this time, the inclined block 18 rotates back. Without the force of the inclined block 18 pressing, under the action of the spring 22, the inclined blocks 19 on the upper and lower sides are driven to leave the groove 8 and return to the annular hole 15. Then, the replacement mechanism can be activated. That is, start the first motor 9. The output end of the first motor 9 drives the pinion 10 to rotate. The pinion 10 rotates one circle to drive the large gear 11 to rotate one-sixth of a circle. The large gear 11 rotates to drive the rotating disk 12 to rotate one-sixth of a circle, and then drives the filter screen 6 inside the purification box 2 to rotate out of the purification box 2 and drives the next rotating shaft 13 and the filter screen 6 at the end of the rotating shaft 13 to rotate into the purification box 2. At this time, the sealing plate 21 around the brand-new filter screen 6 inside the purification box 2 can be driven to snap into the groove 8, and the sealing between the annular plate 14 and the through hole 7 can be completed. That is, reverse-start the second motor. The second motor rotates to drive the driving gear 16 to rotate in the reverse direction. The driving gear 16 rotates to drive the engaging teeth and the inclined block 18 to rotate. The inclined block 18 rotates to squeeze the inclined blocks 19 on the upper and lower sides, thereby driving the inclined blocks 19 on the upper and lower sides to move. The movement of the inclined blocks 19 on both sides drives the connecting ring 20 to move. The movement of the connecting ring 20 drives the sealing plate 21 to move out of the annular hole 15 and snap into the groove 8. At this time, as the connecting ring 20 moves to squeeze the spring 22, the sealing plate 21 snaps into the groove 8, and the gap between the through hole 7 and the annular plate 14 can be filled.

[0034] Although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
