Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and are not intended to limit the present invention.
In the description of the present invention, it should be noted that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
As shown in figures 1 and 3, the invention provides a stepped slag receiving device which comprises a trolley 1 and N slag tanks 2, wherein N is a natural number which is more than or equal to 2. Each slag pot 2 comprises a slag outlet 24, and the slag outlet 24 is arranged at the top of the slag pot 2 and communicated with the top opening of the slag pot 2. The N slag pots 2 are arranged on the trolley 1 at intervals along the length direction of the trolley 1, the top opening of the nth slag pot 2 is positioned below the slag outlet 24 of the (N-1) th slag pot 2, and N is more than or equal to 2 and less than or equal to N. Thus arranged, the smelting slag exceeding the volume of the (n-1) th slag pot 2 can enter the nth slag pot 2 through the slag outlet 24 of the (n-1) th slag pot 2.
The trolley 1 comprises a frame, a drive mechanism mounted in the frame and a plurality of wheels 13 mounted at the bottom of the frame. The frame is provided with N supporting seats 12, the outer wall of the slag pot 2 is provided with a saddle 21 matched with the supporting seats 12, and the supporting seats 12 are in limit connection with the saddle 21. In particular, the saddle 21 comprises a projection and the support seat 12 comprises an upwardly facing recess in which the projection snaps. Under actuating mechanism's drive, wheel 13 rotates, and platform truck 1 drives 2 displacements of sediment jar, and supporting seat 12 can restrict the displacement of sediment jar 2 this moment, avoids sediment jar 2 to empty in the transportation. The installation height of the N supporting seats 12 on the frame is gradually increased or decreased along the length direction of the trolley 1, so that the N slag tanks 2 are arranged in a stepped mode, and the follow-up slag receiving work is guaranteed to be completed smoothly.
During operation, the N slag tanks are placed on the supporting seat respectively, then the N slag tanks are driven by the trolley to reach the position near the smelting furnace, the first slag tank at the maximum height is ensured to be positioned below the smelting furnace, and the slag is firstly received. Along with the liquid sediment in the first slag ladle increases gradually, the liquid level in the first slag ladle rises gradually, highly flushes with the bottom of the slag notch of first slag ladle until, the liquid sediment of the volume that exceeds first slag ladle can get into the second slag ladle through the slag notch of first slag ladle, analogizes in proper order, and it finishes to arrange the sediment until the smelting furnace. The trolley 1 is started to drive the N slag pots 2 to reach the designated positions, and then the tipping device is matched with the tipping seats 22 on the slag pots 2 to drive the slag pots 2 to tip over, so that slag pouring is completed.
The technical personnel in the art can calculate the specific N value according to the slag output of the smelting furnace each time, and avoid resource waste or production accidents caused by overlarge or undersize N values. Preferably, the frame upper berth is equipped with refractory material, still is equipped with round baffle 11 along the periphery of frame, and refractory material cooperation baffle 11 forms one and is located the excessive sediment pond of slag ladle 2 below, and the excessive sediment pond is responsible for accepting the liquid sediment that spills from slag ladle 2, avoids liquid sediment to flow subaerially, reduces the production risk.
As can be seen from fig. 2 and 4, in the first and second embodiments of the present invention, the slag outlet 24 is located between the two trunnions 23 of the slag pot 2, so that damage to the trunnions 23 or other components of the slag pot 2 by the high-temperature liquid slag flowing out of the slag outlet 24 can be avoided. The tap hole 24 is in particular rectangular in cross-section, which facilitates the processing and also makes the tapping process more smooth. In addition, the symmetry axes of the slag outlets 24 of the N slag tanks 2 are all positioned on the same straight line, so that the liquid slag flowing out of the slag outlet 24 at the high position can accurately enter the top opening of the slag tank 2 at the low position, and the overflow amount caused by position deflection is reduced.
As shown in fig. 1 and 3, the first embodiment and the second embodiment of the present invention are different in the configuration and the volume of the slag pot 2. Therefore, the stepped slag receiving device has a wide application range, can be matched with various slag tanks with different shapes and volumes, and solves the problems that the slag tanks are limited in field and cannot receive all slag output at one time in the prior art.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
