It is one of the three major steel containers in a steelmaking plant.

[0003] The tundish has a high frequency of use and a very fast turnover, which requires the tundish to be fast in the construction and preparation process. How to ensure the construction quality of the lining of the tundish in a short construction time is also particularly important. For a long time, the refractory construction of the lining of the tundish has been mainly manual, including transportation, unpacking, and laying, generally using bags of about 25kg. After unpacking, it is lifted and poured around the tire mold for laying. Continuous work leads to high labor intensity for construction workers, dust pollution at the construction site, uneven laying, and low construction efficiency. Summary of the invention

DETAILED DESCRIPTION

[0021] Example 1

[0022] This embodiment is a novel refractory bulk material distribution device, such as Figure 1 and Figure 2 As shown, it includes a workbench 6 and a material unloading mechanism and a supporting mechanism which are arranged on the workbench 6 and are in upper and lower corresponding positions, wherein the material unloading mechanism is fixed on the workbench 6, and the supporting mechanism carries a tundish and can move at the bottom of the workbench, so that different tundishes are located directly below the material unloading mechanism, which is convenient for adding dry materials into the tundish through the material unloading mechanism.

[0023] The unloading mechanism is correspondingly arranged above the working platform 6 through the supporting frame 5, and the supporting frame 5 is fixedly arranged on the upper end surface of the working platform 6. The supporting frame 5 includes a column 51 and an upper beam 52, and the upper beam 52 is welded to the top of the working platform 6 through the column 51. An inclined bracing beam 53 is welded between the column 51 and the upper beam 52. The beams and columns are welded together, and the inclined bracing beam 53 can improve the bearing capacity of the whole frame. The unloading mechanism includes a hopper 1 arranged above the working platform 6, and the top feeding end of the hopper 1 is connected with a silo 2, and the bottom discharging end of the hopper 1 is connected with a unloading port 4. A plurality of unloading ports 4 can be provided, and the plurality of unloading ports are evenly distributed and have the same diameter. The silo 2 is a rectangular frame structure, and the hopper is a funnel structure, so that the dry material is wide in and narrow out, thereby ensuring the continuity of the feeding. The hopper 1 is fixed on the upper beam 52, and the unloading port 4 at the bottom of the hopper 1 passes through the working platform 6 toward the support mechanism. The outer side walls of the silo 2 and the discharge port 4 are both connected with a vibration motor 7 .

[0024] A partition 3 is provided inside the hopper 1 at one end near the discharge port 4. The partition 3 is arranged above the discharge port. The partition 3 includes a hollow partition frame 31 fixedly connected to the inner wall of the hopper 1 and strip plates 32 evenly distributed horizontally in the hollow partition frame 31. The strip plates divide the partition into multiple discharge spaces, which can enable the dry material to fall smoothly and quickly to avoid blockage, and at the same time, the dry material dropped into the middle bag is evenly distributed.

[0025] The support mechanism includes a support frame 8 arranged below the workbench 6, the intermediate package is loaded in the support frame 8, the support frame 8 is installed on a slide plate 9 and the support frame 8 slides on the ground at the bottom of the workbench 6 through the slide plate 9, the slide plate 9 is connected to a pulley on the side facing the ground, and a slide rail for the pulley to slide is provided on the ground. The slide plate 9 moves along a fixed track on the ground through the pulley, and a controllable electric roller device can also be installed to freely set the moving trajectory through the program to move on the flat ground. This electric roller moving device has a multi-directional moving function.

[0026] During construction, after the construction dry material is lifted to the upper part of the silo by the crane, the construction workers operate the crane to load the dry material into the silo, and then discharge the material to the discharge port by controlling the discharge baffle inside the discharge hopper. The discharge port guides the dry material into both sides of the dry material membrane, and controls the discharge speed. At the same time, the tundish support mechanism is started to keep the material receiving part of the lining of the tundish always directly below the discharge port. The moving speed of the tundish can be adjusted according to the discharge speed to ensure uniform material distribution.

[0027] Compared with the feeding method in which the unloading mechanism is moved and the tundish is fixed, the movement of the tundish is safer and more convenient. The movement of the unloading mechanism is laborious and prone to safety problems and inconvenient maintenance due to its high position. The tundish moves on the slide through the support frame, so the material distribution situation can be observed in time and timely adjustments can be made when the material distribution is uneven. It also facilitates the turnover of the tundish.

[0028] Example 2

[0029] Based on Example 1, Figure 3 A material mixing assembly is provided in the hopper 1, and the material mixing assembly includes a material mixing plate 10 provided in the hopper 1. The outer periphery of the material mixing plate 10 is provided with evenly arranged grooves 11 recessed toward the axial direction of the material mixing plate 10. The outer periphery of the material mixing plate 10 located in the direction of the hopper 1 close to the discharge port 4 is in relative sliding contact with the hopper 1.

[0030] As the bottom of the hopper is narrow, the dry material with wide inlet and narrow outlet may be blocked at the bottom of the hopper. The mixing plate in the hopper rotates at a uniform speed under the action of the driving motor. The side of the mixing plate can have a certain gap with the hopper, or it can slide relatively and fit. The dry material is poured into the groove on the mixing plate through the hopper. During the rotation of the mixing plate, the groove filled with dry material gradually moves to the bottom. As the contact space between the mixing plate and the hopper decreases, the larger pseudo-particles that agglomerate in the dry material can be squeezed and crushed into finer particles, avoiding uneven dry material due to agglomeration, and transporting the dry material to the direction of the discharge port and falling when passing through the discharge port. The dry material is continuously transported to the direction of the discharge port as the mixing plate rotates in a cycle, avoiding a large amount of dry material from being blocked at the discharge port.

[0031] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
