Description

Fire-proof curtain in front of converter
Technical Field
The utility model belongs to the technical field of the converter is smelted, especially, relate to a fire curtain before converter stove.
Background
In the process of implementing the present invention, the inventor finds that the prior art has at least the following problems:
in the smelting production of the converter, the operations of adding molten iron and adding scrap steel are required, the furnace mouth is inclined to the front of the furnace by a certain angle to receive the molten iron and the scrap steel, high-temperature flame and a large amount of smoke dust can be ejected from the furnace mouth, and a smoke exhaust hood in the front of the furnace cannot be completely sucked into the smoke exhaust hood due to the angle problem.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an increase fire curtain blocks during the smoke and dust makes its suction enclosure, avoids the smoke and dust to leak, reduces environmental pollution's converter stokehold fire curtain.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is: a fire-proof curtain for a converter front comprises:
a stokehole smoke exhaust hood;
the fixed steel pipe is arranged on the front smoke exhaust cover;
the first end of the chain is provided with a hook, the length direction of the fixed steel pipe is provided with a series of chains, the chains are connected with the fixed steel pipe through the hook, and the chains form the body of the fire-proof curtain.
The furnace front smoke exhaust hood is characterized by further comprising clamping plates, the clamping plates are arranged at two ends of the furnace front smoke exhaust hood, and the fixed steel pipes are arranged in the clamping plates.
The surfaces of the loop chain and the hook are coated with high-temperature resistant coating sodium silicate.
The steel pipe fixing device is characterized in that a series of clamping plates are arranged in the length direction of the fixed steel pipe, and the clamping plates are uniformly distributed in the length direction of the fixed steel pipe.
One of the technical schemes has the advantages that the fireproof curtain is added, smoke dust is blocked to be sucked into the smoke exhaust hood, the smoke dust is prevented from leaking, and the environmental pollution is reduced. The mode that utilizes fixed section and flexible section to combine effectively solves the poor shortcoming of the fastness of fire prevention curtain and high temperature resistance is poor, promotes the hookup reliability of upper segment, chooses for use the less endless chain of swing radius as the flexible section, reduces with the area of scraping of reinforced silo. Meanwhile, the mode of adding the high-temperature-resistant coating into the stainless steel material is adopted, so that the high-temperature-resistant effect is effectively improved. Effectively promotes the service life of the fireproof curtain, reduces the radiation of high temperature to equipment and the leakage of smoke, and has obvious environmental protection effect.

The labels in the above figures are: 1. a furnace front smoke exhaust hood, 2, a fixed steel pipe, 3, a ring chain, 4, a clamping plate, 5 and a hook.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1-2, a fire curtain for a converter front includes:
a stokehole smoke exhaust hood;
the fixed steel pipe is arranged on the front smoke exhaust cover of the furnace;
the first end of the chain is provided with a hook, the length direction of the fixed steel pipe is provided with a series of chains, the chains are connected with the fixed steel pipe through the hook, and the chains form the body of the fireproof curtain.
The furnace front smoke exhaust hood is provided with clamping plates, the two ends of the furnace front smoke exhaust hood are provided with clamping plates, and the fixed steel pipes are arranged in the clamping plates.
The surfaces of the ring chain and the hook are coated with high-temperature resistant coating sodium silicate.
A series of clamping plates are arranged in the length direction of the fixed steel pipe and are uniformly distributed in the length direction of the fixed steel pipe.
The mode that adopts fixed steel pipe and flexible endless chain to combine together adopts major diameter steel pipe to make horizontal fixed shelves, fixes in the stokehold enclosure outside with the cardboard, plays the effect of promotion fixed strength, and the reducible high temperature of this position simultaneously is to the burning loss of fixed point. The hook is connected with the ring chain, so that the ring chain is convenient to damage and replace, and when the scrap steel trough is used for feeding, the flexible ring chain has small swing radius and stronger flexibility and is not easy to hang and fall off.
Stainless steel pipes and stainless steel ring chains are adopted, and high-temperature resistant materials such as sodium silicate and the like are coated before the stainless steel pipes and the stainless steel ring chains are on line. Improve the high temperature resistance and prolong the service life.
The steel pipe mounting position is changed from the bottom of the stokehole smoke exhaust hood to the front, and the steel pipe is fixed by the clamping plate, so that the steel pipe is convenient to damage, disassemble and replace. Sodium silicate is selected as the high-temperature resistant coating to be coated, the service cycle is more than three years, the equipment burning loss is reduced, and the effect of preventing smoke dust from leaking is obvious.
The stokehole smoke exhaust hood is improved, a clamping plate base is welded on the outer side of the smoke exhaust hood, and the steel pipes are fixed by bolts through the clamping plates, so that individual fire curtains are damaged and replaced conveniently; the lower part of the steel pipe is provided with the annular chain, so that the connection is firmer, the flexibility is stronger, and the steel pipe is not easy to hang and deform in use; in order to improve the heat resistance of the fire-proof curtain, stainless steel is selected as the material; the fire-proof curtain is coated with high-temperature resistant materials such as sodium silicate and the like on the surface, so that the service life of the fire-proof curtain is prolonged.
The mode of fixing the steel pipe and the annular chain is adopted, so that the fixing strength is improved, the flexibility effect is enhanced, and the fireproof curtain is not easy to hang and rub and fall off; stainless steel is selected, and high-temperature resistant materials such as silicic acid and the like are coated on the surface of the stainless steel, so that the high-temperature resistant effect is improved, and the service life is prolonged.
One of the technical schemes has the advantages that the fireproof curtain is added, smoke dust is blocked to be sucked into the smoke exhaust hood, the smoke dust is prevented from leaking, and the environmental pollution is reduced. The mode that utilizes fixed section and flexible section to combine effectively solves the poor shortcoming of the fastness of fire prevention curtain and high temperature resistance is poor, promotes the hookup reliability of upper segment, chooses for use the less endless chain of swing radius as the flexible section, reduces with the area of scraping of reinforced silo. Meanwhile, the mode of adding the high-temperature-resistant coating into the stainless steel material is adopted, so that the high-temperature-resistant effect is effectively improved. Effectively promotes the service life of the fireproof curtain, reduces the radiation of high temperature to equipment and the leakage of smoke, and has obvious environmental protection effect.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements can be made without modification to the method and technical solution of the present invention, or the present invention can be directly applied to other occasions without modification, all within the scope of the present invention.
