Description

Iron runner A lid baking equipment

Technical Field

The utility model particularly relates to a blast furnace ironmaking equipment field specifically is a baking equipment of iron runner A lid.

Background

The A cover of the blast furnace front iron runner is key equipment for dust removal of the blast furnace front iron runner, and the service life of the equipment is generally about 1 month to 2 months. 1 to 2 dust removal A covers are needed for standby in an iron runner dust removal A cover installation position. An iron runner dust removal A cover for pouring a refractory material layer is required to be heated and baked before use so as to remove moisture in refractory materials and ensure the service life of the iron runner dust removal A cover. At present, the method of igniting wood in the iron runner A cover is generally adopted in China to bake the iron runner dust removal A cover, and the baking method has the following defects:

1) a large amount of wood is consumed for baking, and the baking cost is high;

2) a large amount of smoke dust generated in the combustion process of the wood can cause serious pollution to the environment in front of the furnace, and the environment-friendly requirement is not met;

3) the baking is not uniform, the moisture in the refractory material cannot be completely removed, and the service life of the cover A of the iron runner is influenced;

4) the baking time is long, and the requirement can be met only by baking for one week generally.

Therefore, it is necessary to design an iron runner A cover baking device which is environment-friendly, energy-saving, efficient and uniform in heating.

Disclosure of Invention

An object of the utility model is to provide a baking equipment of iron runner A lid to improve the efficiency of toasting of iron runner dust removal A lid, reduce and toast the cost, improve and toast the effect, reduce environmental pollution, avoid the wasting of resources.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

an iron runner A cover baking device comprises a baking pipe, a baking frame, a metal hose and a valve; the baking rack is a horizontally placed semi-cylinder, the bottom end is a rectangular plane, the two sides are semi-circles, and the middle part is an upward convex arc surface; the baking pipe is fixed on the middle arc surface of the baking frame and is provided with a flame spray hole corresponding to the refractory layer of the cover A of the iron runner; one end of the metal hose is connected with the main pipe of the baking pipe, and the other end of the metal hose is connected with the gas pipeline through a valve.

Furthermore, the baking tube comprises a main tube and n branch tubes, the main tube is arranged at the bottom end of the semicircular plane at the side edge of the baking frame, the branch tubes are arranged in a semicircular shape on the convex arc surface in the middle of the baking frame, one end of each branch tube is connected with the main tube, and the other end of each branch tube is closed.

Further, the diameter of the baking main pipe is 90-100 mm; the diameter of each baking branch pipe is 25-35mm, flame spray holes are uniformly distributed in each baking branch pipe, the aperture of each flame spray hole is 5-7mm, and the hole distance is 200-300 mm.

Furthermore, the diameter of the metal hose is 50-60mm, and both ends of the metal hose are provided with quick connection ports.

Furthermore, the baking tube and the baking frame are made of high-temperature resistant metal materials.

Advantageous effects

Compared with the prior art, the utility model discloses replaced and used timber to toast iron runner A lid, avoided the influence of the smoke and dust that timber burning produced to the surrounding environment, used moreover the utility model discloses toast and to make the refractory material in the iron runner A lid be heated more evenly and toast efficiently, improved iron runner A lid refractory material's life. Furthermore, the utility model discloses still have simple structure, convenient to use, it is easy to maintain, advantages such as small in investment.
