Description

Technical Field

[0001] This utility model relates to the field of metallurgy, specifically a vent cover device for a slag-quenching tank. Background Technology

[0002] The red slag produced in the converter needs to be cooled by water in the slag-cooling tank. The cooling water generates a large amount of steam upon contact with the slag. If the steam is not discharged in time, an explosion may occur. Therefore, vents are provided around the slag-cooling tank, connected to the drainage system at the bottom of the tank to discharge the steam generated at the bottom. During the slag-cooling process, there is a stirring step. During stirring, steel slag splashes and can clog the vents. Current technology typically uses ribs on the outside of the vents to prevent steel slag from entering, and uses wire to fix and suspend the ribs. However, because the ribs are small, they are easily displaced by impacts with the steel slag, or the fixing wires can be burned through by the high temperature of the steel slag, causing the ribs to fall and allowing steel slag to enter the vents and cause blockage. Furthermore, manually hanging the ribs involves working at height, and improper operation can easily lead to falls. Such accidents occur frequently during slag stirring, creating safety hazards and severely reducing work efficiency. Therefore, designing a device that prevents the ribs from shifting and falling is a problem that needs to be solved. Summary of the Invention

[0003] To address the aforementioned problems, this utility model provides a vent cover plate device for a slag-curing tank, which can prevent the rib plate from shifting or falling off. The specific solution is as follows:

[0004] A vent cover device for a slag-curing tank includes a U-shaped card plate with an opening facing downwards. The width of the slot of the U-shaped card plate matches the width of the tank wall. The front baffle of the U-shaped card plate corresponds to the inlet end of the vent. The height of the front baffle is greater than the depth of the vent on the tank wall. When the slot is inserted into the tank wall, the front baffle covers the inlet end of the vent.

[0005] Furthermore, multiple exhaust vents are arranged sequentially along the height of the pool wall to form an exhaust group;

[0006] There are multiple exhaust assemblies, which are arranged in parallel along the circumference of the pool wall;

[0007] The height of the U-shaped plate corresponds to the depth of the exhaust assembly.

[0008] Furthermore, the U-shaped card plate is made of steel plate.

[0009] Furthermore, a lifting ring is provided in the middle of the top plate of the U-shaped card plate.

[0010] Furthermore, the lifting ring includes two symmetrical ear plates and bolts passing through the two ear plates. The bottom of the two ear plates is fixedly connected to the top plate, and two aligned through holes are opened in the two ear plates respectively. The bolts are connected between the two through holes.

[0011] Furthermore, a rib is provided at the outer angle between the ear plate and the top plate. The rib includes a first plate and a second plate. The first plate is a right-angled triangular structure. The right-angled surface of the first plate is close to the side of the ear plate. The second plate is a rectangular plate at the end of the first plate away from the ear plate.

[0012] Furthermore, a U-shaped buckle is provided, which includes two corner brackets, the inner angle of which is secured to the right-angled edges on both sides of the top plate.

[0013] Furthermore, there are multiple U-shaped buckles, all arranged sequentially along the length of the top plate, with the two corner brackets of the U-shaped buckles located on both sides of the rib plate.

[0014] Furthermore, a U-shaped buckle is provided at the gap between the two ear plates, and the tops of the two corner brackets of the U-shaped buckle extend into the gap and connect in the gap.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] 1. This utility model uses a U-shaped clamping plate to engage with the pool wall, which prevents the steel slag splashed during the stirring of the slag-smoking pool from colliding with the front baffle and causing the front baffle to shift, thereby blocking the vent hole;

[0017] 2. This utility model sets a lifting ring on the top of the U-shaped plate. Before pouring and stirring the slag, the U-shaped plate is lifted by a crane to insert it into the pool wall. When slag is simmering, the U-shaped plate can be lifted to disassemble it from the pool wall, which avoids the problem of the rib plate falling off in the prior art. It is safe, reliable and easy to operate.

[0018] 3. This utility model has a reinforcing structure on the top of the U-shaped pallet, which strengthens the top of the U-shaped pallet and prevents the top of the U-shaped pallet from tearing or deforming due to high temperature or collision during the mixing of steel slag.
