[0038] See also Figure 1 、 Figure 2 and Figure 8 , a dust removal mechanism for an air outlet of a casting furnace, comprising:

[0039] A forging electric furnace 1 includes an electric furnace body 11, an air outlet 12 is provided on the upper surface of the electric furnace body 11, and the air outlet 12 is communicated with the electric furnace body 11. A fixing block 13 is provided on the surface of the electric furnace body 11, and a mounting cover 15 is provided on a side of the fixing block 13 away from the electric furnace body 11 by screws. A semi-threaded hole 14 is provided between the fixing block 13 and the mounting cover 15, and two adjacent semi-threaded holes 14 form a complete threaded hole;

[0040] Based on the above, the electric furnace main body 11 is the existing technology, so its specific internal structure and working principle are not repeated here. The air outlet 12 is interconnected with the electric furnace main body 11, and the airflow generated inside the electric furnace main body 11 can be discharged from the air outlet 12. The fixing block 13 and the mounting cover 15 are connected to each other by screws. The setting of the threaded hole enables the threaded rod 9 to be threadedly connected to the forging furnace 1 and extend between the fixing block 13 and the mounting cover 15.

[0041] like Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 9 As shown, the water tank 4 is arranged on the outer surface of the forging furnace 1 and is connected to the air outlet 12 of the forging furnace 1 through the fan 2, the air pipe 3 and the top cover 5. The top cover 5 includes an air inlet pipe 52 and an exhaust pipe 53;

[0042] The water tank 4 includes a box body 41, a roller 42 is provided on the lower surface of the box body 41, a slot 43 is provided on the side of the box body 41 away from the electric furnace body 11, and limit plates 44 are provided on both side walls of the box body 41, and a limit groove is formed between adjacent limit plates 44 on the same side;

[0043] The top cover 5 includes a top cover plate 51, which is screwed to the top of the box body 41. An air intake pipe 52 and an exhaust pipe 53 are provided on the upper surface of the top cover plate 51. The air intake pipe 52 and the exhaust pipe 53 are both connected to the box body 41. The air intake pipe 52 extends into the interior of the box body 41. An annular groove 54 is provided on the outer surface of the air intake pipe 52. The annular groove 54 is provided below the top cover plate 51, and a sealing ring is provided inside the annular groove 54.

[0044] Based on the above, the water tank 4 and the top cover 5 are connected to each other by screws. At this time, the water tank 4 is connected to the air outlet 12 of the forging furnace 1 through the air inlet pipe 52, the air supply pipe 3 and the fan 2. At this time, the fan 2 is powered on to transport the airflow generated in the forging furnace 1 to the water tank 4;

[0045] The setting of the roller 42 makes the water tank 4 easy to move, and the slot 43 enables the water tank 4 to cooperate with the movable block 8, spring 10 and other structures to be fixed. The setting of the limit plate 44 and the limit slot enables the floating member 6 to move only vertically, while the two spaces above and below the floating member 6 can be connected to each other. The air inlet pipe 52 plays the role of air intake, while the air outlet pipe 52 plays the role of air outlet. The annular groove 54 cooperates with the sealing ring to ensure sufficient sealing between the air inlet pipe 52 and the vertical movable pipe 7.

[0046] like Figure 6 、 Figure 7 、 Figure 11 as well as Figure 10 As shown, the vertical movable pipe 7 is arranged inside the water tank 4 and outside the air intake pipe 52. The vertical movable pipe 7 includes a main body 71. The main body 71 is arranged outside the air intake pipe 52, and its inner surface is in contact with the sealing ring. The outer surface of the main body 71 is provided with a partition 72, and the bottom end of the main body 71 is provided with a hollow threaded cylinder 73;

[0047] The floating member 6 is connected to the vertical movable tube 7 via a nut. The floating member 6 includes a hollow plate 61. A connecting hole 62 is provided at the center of the upper surface of the hollow plate 61. The hollow threaded barrel 73 passes through the connecting hole 62. The diameter of the partition 72 is larger than the diameter of the connecting hole 62. An exhaust port 63 is provided on the upper surface of the hollow plate 61. Limit blocks 64 are provided at both ends of the hollow plate 61. The limit blocks 64 extend into the interior of the limit groove.

[0048] Based on the above, the provision of the vertical movable tube 7 ensures that the gas discharged from the exhaust pipe 52 can still be passed into the water body after the floating member 6 moves vertically. During this process, the length of the vertical movable tube 7 extending into the water body remains constant. The provision of the partition 72 and the hollow threaded cylinder 73 enables the vertical movable tube 7 to be connected to the floating member 6 via a nut.

[0049] The setting of the floating part 6 has an adaptive effect, so that the length of the vertical movable tube 7 extending into the water body remains constant, thereby avoiding the situation where the vertical movable tube 7 is blocked after the dust in the water body increases. The setting of the exhaust port 63 enables the upper and lower spaces of the floating part 6 to be connected to each other, and the limit block 64 cooperates with the limit groove to enable the floating part 6 to move only vertically.

[0050] like Figure 3 、 Figure 4 、 Figure 5 as well as Figure 12 As shown, a movable block 8 is provided between the fixed block 13 and the mounting cover 15, and the movable block 8 extends into the interior of the slot 43. A spring 10 is provided between the movable block 8 and the fixed block 13 and the mounting cover 15;

[0051] A threaded rod 9 is provided between the semi-threaded holes 14 , the threaded rod 9 is threadedly connected to the threaded holes and contacts the movable block 8 , and the threaded rod 9 extends to the outside of the fixed block 13 ;

[0052] The movable clamping block 8 includes a movable plate 82. A transverse clamping block 81 is provided on the side of the movable plate 82 close to the water tank 4. The side of the transverse clamping block 81 close to and away from the forging furnace 1 are both provided with inclined surfaces 83. The length of the inclined surface 83 is less than the length of the clamping slot 43.

[0053] Based on the above, the threaded rod 9 plays the role of fixing the movable block 8. By twisting the threaded rod 9, the threaded rod 9 is moved in the direction away from the water tank 4. At this time, the movable block 8 moves in the direction away from the water tank 4 under the action of the elastic force of the spring 10. When the spring 10 returns to its normal state, the inclined surface 83 moves to the outside of the slot 43. At this time, the water tank 4 can be removed by pulling it, and the water tank 4 can be reinstalled by the reverse operation. The setting of the inclined surface 83 makes it possible for the threaded rod 9 to be tightened. There is a lateral component of the interaction force between the water tank 4 and the movable block 8 during the installation and disassembly process, so that the water tank 4 can be directly connected. The connection is a preliminary connection method, and it can be subsequently fixed for a second time by tightening the threaded rod 9.

[0054] In actual use of this embodiment, the fan 2 is powered on to transport the hot air generated in the forging furnace 1 to the interior of the water tank 4. The hot air entering through the air inlet pipe 52 is directly passed into the water body. At this time, the hot air fully contacts the water body and then floats to the top of the floating member 6 and is discharged from the exhaust pipe 53. During this process, dust in the hot air remains in the water body, so that the airflow and dust are separated. In addition, the heat in the air is transferred after contacting the water body, that is, the temperature of the hot air is reduced.

[0055] During the above process, the floating member 6 ensures that the length of the vertical movable tube 7 extending into the water remains constant, that is, the length of the main body 71 immersed in the water remains constant, thereby preventing the vertical movable tube 7 from being blocked by excessive accumulation of dust in the water.

[0056] The arrangement of the movable clamping block 8 and the spring 10 enables the water tank 4 to be directly connected to the forging furnace 1 by clamping. Since the clamping method is not stable, the water tank 4 can be directly pulled to be disassembled and installed. The arrangement of the threaded rod 9 enables the water tank 4 and the forging furnace 1 to be fixed for a second time after being clamped to each other, so as to achieve a sufficiently stable fixation between the water tank 4 and the forging furnace 1.

[0057] The dust removal mechanism, by setting up structures such as a water tank 4, allows the hot air generated by the forging electric furnace 1 to be directly introduced into the water, so as to achieve the effect of separating dust and air from each other, and the heat of the hot air is reduced after being cooled by the water body. At this time, when the hot air is introduced into the next processing equipment, it can effectively avoid the damage to the processing equipment. In addition, the device has a simple structure, low cost, and is easy to use.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
