[0032] The top of the mobile house 1 is provided with a movable smoke pipe 3 connected to the interior thereof, and an opening for the hoisting mechanism to enter and exit. The main smoking pipe 2 is supported on a column (not shown) of a foundation 5. The air outlet of the main smoking pipe 2 is connected to a dust removal system, and the main smoking pipe 2 has a plurality of butt joints 21 connected thereto, and each butt joint 21 is provided with an electric air valve 6.

[0033] When the electric furnace ladle is poured on one of the workstations on the foundation 5, the mobile house 1 is moved to the workstation by the sliding mechanism 4 and stops, and the mobile house 1 covers the periphery of the electric furnace on the workstation. At the same time, the mobile smoke duct 3 on the mobile house 1 forms a sealed connection with a docking tube 21 on the main smoking duct 2, and the electric air valve 6 provided on the docking tube 21 is in an open state, and the electric air valves 6 on the remaining docking tubes 21 are in a closed state. At this time, the smoke generated by the electric furnace is covered in the mobile house 1 and transferred to the inside of the main smoking duct 2 through the mobile smoke duct 3, so that the dust removal system sucks out the smoke in the main smoking duct 2 and removes and purifies it.

[0034] Furthermore, in order to further improve the smoke capture efficiency and to have multiple smoking outlets, the mobile house 1 has multiple smoking outlets, and each smoking outlet is connected to the mobile smoke duct 3 .

[0035] like Figure 1 , 2 As shown, in order to capture the smoke overflowing from the side of the electric furnace, a side smoking mechanism 7 is also included, and the side smoking mechanism 7 includes a smoke collecting pipe 71 and a side smoking hood 72. The side smoking hood 72 is arranged on the side wall of the mobile house 1 and is located on one side of the electric furnace on the foundation 5, and the side smoking hood 72 is connected to the mobile smoke duct 3 through the smoke collecting pipe 71. The side smoking hood 72 is provided with a plurality of parallel grid plates at the smoking port, and the grid plates are rotated to adjust their angles to ensure the efficiency of the side smoking hood 72 in capturing smoke.

[0036] like Figure 1 , 2 As shown, in order to facilitate the adjustment of smoke output and make the structure more reasonable, the smoke collecting pipe 71 is also provided with a manual air valve 73 for adjusting the smoke output. The smoke collecting pipe 71 is connected to the movable smoke pipe 3 through a bend pipe 74.

The limiter 94 is installed on the limiter seat 95, the top rod of the cylinder 91 is fixedly connected to the end of the telescopic tube 92, and a limit plate 93 is provided on the mobile smoke exhaust pipe 3. When the mobile house 1 moves to the corresponding workstation on the foundation 5, and the limit plate 93 is close to the limiter 94, the limiter 94 sends a corresponding signal, and the mobile house 1 stops moving. At this time, the driving cylinder 91 is activated, and the telescopic tube 92 is extended to form a sealed docking with the end of the mobile smoke exhaust pipe 3. At the same time, the electric air valve 6 on the docking pipe 21 is in an open state. The wear-resistant tube is preferably a wear-resistant polytetrafluoroethylene tube.

The top smoking hood 81 is fixed on the top of the mobile house 1 and connected to the inside thereof, and the top smoking hood 81 is connected to the mobile smoke duct 3 through the smoking branch pipe 82. The top smoking hood 81 is a trumpet-shaped structure, which can increase the smoking port area of ​​the top smoking hood 81.

[0039] When the side smoking mechanism 7 and the top smoking mechanism 8 of the utility model are used together, the side smoking hood 72 and the top smoking hood 81 have a certain height difference. The side smoking hood 72 can suck the smoke overflowing from the periphery of the electric furnace. If some smoke still rises to the top of the electric furnace, it will be sucked into the mobile smoke pipe 3 by the top smoking hood 81, which greatly improves the capture efficiency of the smoke overflowing from the electric furnace.

[0040] like Figure 1 , 2 As shown in Figures 4 and 5, in order to facilitate the efficient and accurate movement of the mobile house to the electric furnace at different workstations for docking, the sliding mechanism 4 includes a guide rail 41, an end beam 42, a track wheel 43 and a travel motor 44. The foundation 5 is provided with a guide rail 41, and the bottom of both sides of the mobile house 1 are provided with end beams 42, and both ends of the end beams 42 are provided with track wheels 43 rotatably connected thereto, the track wheels 43 are rotatably matched with the corresponding guide rails 41 on the foundation 5, and the travel motor 44 is transmission-connected to the track wheel 43 at one end of the end beam 42.

[0041] like Figure 5 As shown, in order to ensure the stability of the mobile house movement, guide mechanisms are respectively provided at both ends of the end beam 42, and the guide mechanisms include end plates 45 and guide wheels 46. The end plates 45 are fixed to the ends of the end beams 42, and two guide wheels 46 rotatably connected to the end plates 45 are provided at the bottom of the end plates 45, and the guide wheels 46 rotatably cooperate with the guide rails 41.

[0042] Further, such as Figure 5 As shown, in order to prevent the side of the mobile house from colliding with foreign objects, an anti-collision block 47 is further provided on the outer side wall of the end plate 45.

[0043] like Figure 1 As shown, in order to match the actual structure of the foundation and to be more reasonable, to prevent the mobile house from interfering with the surroundings and to make it difficult to operate the electric furnace, the foundation 5 is a stepped structure as a whole, and a set of guide rails 41 is provided on the lower surface, and guide rail columns 51 are provided on the upper surface, and another set of guide rails 41 is fixed on the fixed platform 52 of the guide rail columns 51 on the upper surface.

[0044] like Figure 1 , 2As shown, in order to further improve the rationality of the structure, the mobile house 1 includes a top plate 11, a vertical plate 12, a long side plate 13 and a short side plate 14. The vertical plates 12 and the short side plates 14 are respectively provided at both ends of the top plate 11 in the length direction, and the long side plates 13 are respectively provided on both sides in the width direction. Through openings are provided on the top plate 11 and the long side plates 13 on one side of the mobile house 1 to facilitate the entry and exit of the lifting mechanism.

[0045] The specific working process of the utility model is:

[0046] The main smoking duct 2 is connected with the air inlet of the dust removal equipment. When the electric furnace 100 on one of the stations on the foundation 5 is poured, the mobile house 1 is driven by the walking motor 44 in advance, so that the track wheel 43 rolls along the guide rail 41 to the station and stops. When the mobile house 1 moves to the corresponding station on the foundation 5, and the limit plate 93 is close to the limiter 94, the limiter 94 sends a corresponding signal, the mobile house 1 stops moving, and is caged around the electric furnace on the station. At this time, the driving cylinder 91 is actuated, and the telescopic tube 92 is extended to form a sealed docking with the end of the mobile smoke pipe 3. At the same time, the electric air valve 6 on the docking tube 21 is in an open state to ensure that the mobile smoke pipe 3 is accurately docked with the telescopic tube 92. The electric air valves 6 on the remaining docking tubes 21 are in a closed state.

[0047] The hoisting mechanism (electric hoist) enters from the opening of the mobile house 1 and hangs the ladle. When the electric furnace is pouring the ladle, the smoke generated by the electric furnace is enveloped in the mobile house 1 and transferred to the main smoking duct 2 through the mobile smoke pipe 3, so that the dust removal system sucks out the smoke in the main smoking duct 2 and dedusts and purifies it. Finally, the ladle is moved out from one side of the mobile house 1.

[0048] like Figure 6 As shown, when the electric furnace 100 at other stations is pouring ladles, the mobile house 1 only needs to be moved to the station and parked by the sliding mechanism 4. Of course, the utility model can be expanded and applied to be used with multiple electric furnaces.

[0049] The utility model is used for switching back and forth between multiple electric furnaces and can effectively prevent smoke overflowing from the electric furnaces, which not only improves the efficiency of capturing smoke, but also effectively avoids pollution to the working environment, prevents the room temperature of the working environment from rising due to smoke, and improves the comfort of the staff.
