Description

Novel chute apron

Technical Field

The utility model belongs to smelt trade production facility field relates to a novel chute apron.

Background

For solving the sealed of high temperature melt discharge chute in the trade production process is smelted to the tradition, the chute apron all adopts clay brick goods or steel sheet interior thermal-insulated cotton of clamp to cover and keeps warm, and these two kinds of apron structures are less, and when the chute apart from longer time, the single set of use of tradition chute apron is more in quantity, and the joint position between the chute apron is more, and the gap is many, and the air leakage is serious, and because single set is in quantity many simultaneously, work efficiency is low when post staff uses the maintenance chute. In addition, the service life of the traditional chute cover plate is short, and the clay brick cover plate is easy to break when in use; when the heat insulation cotton cover plate is used, the heat insulation cotton falls off after the heat insulation surface fixing net falls off, so that the steel shell is burnt.

To sum up, traditional chute apron is sealed, the heat preservation effect is poor, leads to the fuse-element heat dissipation fast and easily with the air contact, oxidation in advance, and traditional chute apron life is short moreover, causes steel and refractory material's waste.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides a novel chute cover plate which can preserve heat, prevent oxidation, has long service life and reduces the consumption of refractory materials.

In order to achieve the above purpose, the technical solution of the present invention is as follows:

a novel chute cover plate comprises a steel shell, a heat insulation layer, lifting lugs and reinforcing ribs; the method is characterized in that: the steel shell is an open cuboid; the reinforcing ribs are welded on the back of the steel shell bottom plate at equal intervals; the lifting lugs are welded at two ends of the steel shell;

the heat insulation layer comprises arc-shaped steel bars and concrete; the arc-shaped reinforcing steel bars are welded on the bottom plate in the steel shell; the concrete mixed arc-shaped reinforcing steel bars form a heat insulation layer. Manufacturing a plurality of chute cover plates with corresponding sizes according to the specific shape and size of the chute; the crane seals the chute cover plate on the chute through the lifting lugs; the heat insulating layer faces downwards during installation, the reinforcing ribs face upwards, and the chute cover plates are connected in a pairwise mode when the plurality of chute cover plates are installed.

As a further technical improvement, the arc-shaped steel bars are in a semi-arc shape and 20mm lower than the bottom edge of the steel shell. The concrete can tightly buckle the arc-shaped steel bar after solidification, so that the concrete is fixed in the steel shell and cannot fall off; the arc-shaped reinforcing steel bars are 20mm lower than the bottom edge of the steel shell, so that the heat insulation layer is guaranteed to have enough thickness.

As a further technical improvement, the method is characterized in that: the reinforcing ribs are distributed on the outer part of the bottom plate of the steel shell in the longitudinal direction and the transverse direction and are crossed. The steel shell structure is more stable and is not easy to deform.

As a further technical improvement, the lifting lugs and the reinforcing ribs are arranged on the same surface of the steel shell; the lifting lug is provided with a through hole. The lifting lugs are arranged on the same side of the reinforcing rib, and are convenient to hoist.

The utility model discloses a theory of operation:

when the chute flows into the solution, the heat insulation layer on the chute cover plate can timely retain the high temperature generated by the solution; when the chute cover plate is installed, the two chute cover plates are tightly connected, so that the solution is isolated from the outside air; the heat insulation layer isolates most of temperature, and the steel shell is not easy to deteriorate; the steel shell is difficult for structural deformation under the effect of strengthening rib to guarantee that the insulating layer is difficult for taking place not hard up so that the fracture. The crane passes through the hook lug during installation, can make the insulating layer down fast, and the strengthening rib is up.

Compared with the prior art, the utility model has the advantages and beneficial effect as follows:

1. the utility model discloses can use the crane hoist and mount through the lug, improve post staff's work efficiency.

2. The utility model discloses at steel-shelled internal weld arc reinforcing bar, fix, support the concrete, form reinforced concrete apron, improved the life of chute apron greatly, less refractory material's consumption.

3. The utility model discloses be equipped with the strengthening rib, effectively avoid this chute apron to take place to warp.

4. The utility model discloses can carry out large size processing and use for when the longer chute of distance, it is bad to reduce the sealed that causes when connecting.

5. The utility model discloses be equipped with the insulating layer, energy saving and consumption reduction, sealed simultaneously, the heat preservation effect is better.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Example 1:

a novel chute cover plate comprises a steel shell 1, a heat insulation layer, a lifting lug 3 and a reinforcing rib 4; the steel shell 1 is an open cuboid; the reinforcing ribs 4 are welded on the back of the bottom plate of the steel shell 1 at equal intervals; the lifting lugs 3 are welded at two ends of the steel shell 1;

the heat insulation layer comprises arc-shaped steel bars 2 and concrete 6; the arc-shaped steel bars 2 are welded on the bottom plate in the steel shell 1; the arc-shaped steel bars 2 and the concrete 6 form a heat insulation layer. The chute is sealed by connecting and installing a plurality of novel chute cover plates. The single novel chute cover plate has a large structure, and the connection of the chute cover plate is reduced; manufacturing a plurality of chute cover plates with corresponding sizes according to the specific shape and size of the chute; the crane seals the chute cover plate on the chute through the lifting lugs 3; when the chute cover plate is installed, the heat insulation layer faces downwards, the reinforcing ribs 4 face upwards, and the chute cover plates are connected in a pairwise and tight mode.

When the chute flows into the solution, the heat insulation layer can timely retain the high temperature generated by the solution; when the chute cover plate is installed, the two chute cover plates are tightly connected, so that the solution is isolated from the outside air; the heat insulation layer isolates most of temperature, and the steel shell 1 is not easy to deteriorate; the steel shell 1 is not easy to deform under the action of the reinforcing ribs 4, so that the thermal insulation layer is not easy to loosen and break. The crane passes through hook lug 3 during the installation, can make the insulating layer down fast, and strengthening rib 4 is up.

Example 2:

the difference from the embodiment 1 is that the arc-shaped steel bar 2 is in a semi-arc shape and 20mm lower than the bottom edge of the steel shell. The concrete 6 can tightly buckle the arc-shaped steel bar 2 after being solidified, so that the concrete is fixed in the steel shell 1 and cannot fall off; the arc-shaped steel bars 2 are 20mm lower than the bottom edge of the steel shell 1, so that the heat insulation layer is guaranteed to have enough thickness.

The reinforcing ribs are distributed on the outer part of the bottom plate of the steel shell 1 in the longitudinal direction and the transverse direction and are crossed. The steel shell 1 has more stable structure and is not easy to deform.

The lifting lugs 3 and the reinforcing ribs 4 are arranged on the same surface of the steel shell 1; the lifting lug 3 is provided with a through hole 5. The lifting lugs 3 are arranged on the same surface of the reinforcing rib 4, and are convenient to hoist.
