Description

Technical Field

[0001] The utility model belongs to the technical field of metallurgical equipment, and particularly relates to a heat-insulating cover of an empty molten iron tank that can be raised and lowered while being fixed. Background Art

[0002] The molten iron ladle is a container used to hold the molten iron discharged from the iron-making blast furnace. After being filled with molten iron, the molten iron ladle will be sent to the steelmaking workshop. The molten iron ladle is usually transported by a locomotive, which runs along the track and the molten iron ladle is installed on the locomotive.

[0003] The lid of the molten iron tank needs to be opened before entering the workshop, and the lid can be closed after filling is completed and out of the workshop. The molten iron tank is in an open state while waiting for filling in the workshop, which causes the heat in the molten iron tank to dissipate quickly, and the life of the tank refractory material is shortened during the temperature rise and fall, which is not conducive to the improvement of economic benefits. Utility Model Content

[0004] The utility model aims to provide a heat-insulating cover which can be lifted and lowered at a fixed position for an empty molten iron tank, so as to cover the molten iron tank to be filled, reduce heat loss, and increase the service life of the tube body.

[0005] The utility model adopts the following technical scheme: a heat preservation cover of a molten iron empty tank fixed in a lifting position, comprising an outer frame located on both sides of a locomotive track, and an electric push rod is installed at the bottom end of the outer frame;

[0006] The output end of the electric push rod faces upward, and an inner frame is connected to the output end;

[0007] The top ends of the two inner frames are respectively connected to two ends of the same cover body;

[0008] The electric push rod is used to retract when the empty molten iron tank runs to the lower end of the cover body, so that the cover body covers the open opening of the empty molten iron tank.

[0009] Furthermore, the inner frame includes a bottom cross bar, and upper portions of both ends of the bottom cross bar are connected to vertical poles, and top ends of the vertical poles are fixedly connected to the cover body.

[0010] Further, the outer frame includes two uprights, and the uprights are arranged parallel to the uprights;

[0011] A tubular slide is arranged on one side of the column close to the pole, and the pole passes through the tubular slide.

[0012] Furthermore, a support frame is arranged on the top of the outer frame, and the support frame is used to support the cover body.

[0013] Furthermore, an oblique support rod is arranged between the cover body and the vertical rod.

[0014] The beneficial effect of the utility model is that the utility model sets an outer frame at fixed positions on both sides of the locomotive running track, and controls the lifting and lowering of the cover body by an electric push rod. When an empty molten iron tank waiting for filling passes by, the electric push rod can be controlled to make the cover body cover the empty molten iron tank to avoid heat loss in the empty molten iron tank. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 This is a structural schematic diagram of a heat-insulating cover of a molten iron empty tank that can be raised and lowered in a fixed position according to an embodiment of the utility model;

[0016] Among them: 1. Outer frame; 2. Inner frame; 3. Cover body; 4. Tubular slide; 5. Electric push rod. DETAILED DESCRIPTION

[0017] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0018] The utility model discloses a heat-insulating cover for a molten iron empty tank which can be lifted and lowered. Figure 1 As shown, it includes an outer frame 1 located on both sides of the locomotive track, and an electric push rod 5 is installed at the bottom end of the outer frame 1; the output end of the electric push rod 5 faces upward, and the output end is connected to the inner frame 2; the top ends of the two inner frames 2 are respectively connected to the two ends of the same cover body 3; the electric push rod 5 is used to retract when the empty molten iron tank runs to the lower end of the cover body 3, so that the cover body 3 covers the open mouth of the empty molten iron tank.

[0019] The utility model sets an outer frame 1 at fixed positions on both sides of the locomotive running track, that is, the outer frame 1 is fixed by concrete pillars on both sides of the iron transport line at the bottom of the blast furnace. The lifting and lowering of the cover body 3 is controlled by the electric push rod 5. When an empty molten iron tank is waiting to be filled, the electric push rod 5 can be controlled to make the cover body 3 cover the empty molten iron tank to prevent heat loss in the empty molten iron tank.

[0020] The outer frame 1 can be fixedly mounted on the concrete platforms on both sides of the track. In order to avoid affecting the passing of the locomotive, it has higher columns so that its top is located above the locomotive. The outer frame 1 is a frame structure composed of a number of beams and columns.

[0021] like Figure 1 As shown, the inner frame 2 includes a bottom cross bar, and the upper parts of both ends of the bottom cross bar are connected to vertical poles, and the top ends of the vertical poles are fixedly connected to the cover body 3. The main function of the inner frame 2 is force transmission, that is, the force of the electric push rod 5 is transmitted to the cover body 3, so as to control the lifting and lowering of the cover body 3. Since the area of ​​the cover body 3 is larger than the opening of the molten iron ladle, the cover body 3 needs to be supported in multiple directions to ensure the stability of the control. In addition, in order to further enhance the stability of the support structure, an oblique support rod is provided between the cover body 3 and the vertical pole.

[0022] As a specific implementation, the outer frame 1 includes two columns, which are arranged in parallel with the poles; a tubular slide 4 is arranged on one side of the column close to the pole, and the pole passes through the tubular slide 4. By setting the tubular slide 4, the position of the inner frame 2 can be limited, thereby ensuring its stability during movement.

[0023] In one embodiment, a support frame is provided on the top of the outer frame 1, and the support frame is used to support the cover body 3. When there is no molten iron ladle to be filled, the cover body 3 is placed on the support frame to reduce the force on the electric push rod 5 and increase its service life.

[0024] It should be noted that the cover body 3 in this embodiment is made of high temperature resistant fireproof material and is connected to the inner frame 2 by bolts. The insulation cover can also be made into an equal square module with steel, steel plate, etc., embedded on the top of the inner frame 2, and the connection is firm and detachable for easy replacement of insulation cotton.

[0025] In addition, a limit switch can be installed on the motion track of the cover 3 to accurately control the lifting position of the cover 3. A monitoring camera can also be installed at a suitable position, and the electrical control system of the lifting device can be connected to the main control room screen for remote control operation.

[0026] The working process of the utility model is:

[0027] When the iron ladle to be filled stops below the cover 3, the electric push rod 5 is controlled to fall down and the cover 3 covers the open mouth of the iron ladle. When the iron ladle needs to move, the electric push rod 5 is controlled to be angry and the cover 3 is separated from the iron ladle.

[0028] In summary, during the loading process, the movable insulation cover of the molten iron tank can be controlled by remote control to better seal the tank mouth, reduce heat loss, reduce the temperature change of the empty molten iron tank, and increase the service life of the tank.
