Description

Metal smelting pouring protection system

Technical Field

The invention relates to a metal smelting safety protection device, in particular to a metal smelting pouring protection system.

Background

In the metal smelting industry, for example, molten iron transfer is involved during iron making, a dumping accident is easily caused due to equipment aging and other reasons in the transfer process, molten iron splashes, workers cannot evacuate quickly to cause personal injury, and meanwhile, the molten iron can flow to a remote place to cause secondary disasters such as fire disasters, and the technical solution is still to be solved.

Disclosure of Invention

In order to solve the problems, the invention provides a metal smelting pouring protection system.

The technical scheme adopted by the invention is as follows: the utility model provides a metal smelting protection system that tumbles, its characterized in that is including the board that melts down, the grid, the refluence way and hold the pond, the other slot that is equipped with of removal orbit is transported along the molten iron, the ditch inslot is equipped with the wall, the grid falls on slot border and wall, be equipped with the step in the grid, the board that melts down falls into the grid and supports on the step, it staggers with the grid position to hold pond position, the ditch bottom forms the refluence way that the pond was held to the UNICOM for the inclined plane, the snakelike fusing rope of having arranged in grid lower part, fusing rope diversion position is equipped with the rope sheave of connection on the grid, fusing rope one end is fixed on the grid, the fusing rope other end is connected with extension spring one end, the extension spring other end is connected with the travel switch stroke pole, the fusing rope relies on extension spring to tighten back travel switch and is the disconnection, fusing rope disconnection travel switch resets closed, fusing rope provides the signal that tumbles for emergency system, fusing rope disconnection temperature is less than 200 degrees when being heated, the board that melts down is heated is less than 200 degrees, the fusing rope is less than two strands, it establishes bellied spacer bar in the holding pond.

Furthermore, the fusing rope is a rope made of more than two materials.

The molten iron storage tank is usually arranged beside a molten iron transfer moving track, does not affect the movement of personnel even with the ground, and when the molten iron inclines, the falling molten iron instantly melts the smelting shrinkage plate, so that the molten iron falls into the groove through the grating and enters the containing tank through the flow guide channel, the amount and the speed of splashing to the periphery can be effectively reduced, space and time are provided for quick evacuation of personnel, the peripheral burning probability can be effectively reduced, and the occurrence of linked side disasters is reduced; meanwhile, the fusing rope is fused to provide a dumping signal for the emergency system, and a preset control means can be effectively and timely adopted.

Detailed Description

The embodiment of the invention is shown in figures 1 and 2, the metal smelting pouring protection system is provided with a collapsing plate 1, a grid 2, a pouring channel and a containing pool 3, a groove 4 is arranged beside a molten iron transferring moving track, the width of the groove can be set according to the amount of transferred molten iron, the groove is wider when the amount is larger, the groove is narrower when the amount is smaller, a supporting partition 5 is arranged in the groove, the grid falls on the edge of the groove and the partition to realize stable supporting landing, the grid can be made of hot poor conductor materials or the surface is provided with the hot poor conductor materials, a step 6 is arranged in the grid, the collapsing plate falls on the grid and is supported on the step, the collapsing plate is made of materials with the collapsing temperature of less than 200 ℃, the containing pool is staggered with the grid, the bottom of the groove is an inclined plane 7 to form a backflow channel communicated with the containing pool, the snakelike fusing rope 8 of having arranged of grid lower part, snakelike arranging can make vertically or transversely, fusing rope diversion position is equipped with the rope sheave of connection on the grid, fusing rope one end is fixed on the grid, the fusing rope other end is connected with extension spring one end, the extension spring other end is connected with the travel switch stroke pole, the fusing rope relies on extension spring to tighten back travel switch and is the disconnection, fusing rope disconnection travel switch resets closed, the rope sheave, a spring, not see in the travel switch picture, fusing rope fusing can provide the signal of pouring down for emergency system, can effectual timely take and predetermine the control means, go into to cut off fuel supply, fire control facility starts, harmful gas discharges etc, fusing rope is heated the disconnection temperature and is less than 200 degrees.

The molten iron pouring device is arranged beside a molten iron transferring and moving track at ordinary times, does not affect the movement of personnel even with the ground, and can instantly melt the molten shrinkage plate by pouring the falling molten iron when the molten iron inclines, so that the molten iron falls into the groove through the grating and enters the accommodating pool through the flow guide channel, thereby effectively reducing the amount and speed of splashing to the periphery, providing space and time for personnel to evacuate quickly, effectively reducing the peripheral burning probability and reducing the occurrence of interlocking side disaster; meanwhile, the fusing rope is fused to provide a dumping signal for the emergency system, and a preset control means can be effectively and timely adopted.

When the method is implemented, the fusing rope is more than two strands of ropes, so that the reliability is improved; the fusing rope is a rope consisting of more than two materials, the inner layer can be a material providing better tension, and the inner layer can be a material providing better aging resistance, so that the comprehensive performance is improved; a raised isolation rib is arranged in the containing pool; the cooled ingot can be better taken out.

In summary, the present invention is only a preferred embodiment, and all equivalent modifications and additions made by the present application are considered to be within the technical scope of the present invention.
