Abstract
The utility model provides a blown nozzle roaster which comprises a roaster body and an exhaust tube, wherein the exhaust tube is disposed at the lower portion of the roaster. The blown nozzle roaster is characterized by further including a blowing mechanism, the blowing mechanism comprises a blowing tube and a compressed air generation device, an air inlet of the blowing tube is connected with an air outlet of the compressed air generation device, the air outlet of the blowing tube is arranged inside the exhaust tube, and the air outlet of the blowing tube is toward the outlet end of the exhaust tube. The blown nozzle roaster isn't provided with an air blower so that investment in the blown nozzle roaster is little and cost is low; meanwhile, the blown nozzle roaster adopts a blowing and exhausting mode in operation so that no high-temperature gas flows through the compressed air generation device and the device isn't damaged due to high temperature and humidity of a high-temperature airflow. The blown nozzle roaster is high in equipment reliability.
Description
Technical field
The utility model relates to the apparatus for baking of the pans molten steel delivery port in the metallurgy industry conticaster equipment, particularly relates to a kind of air blowing type mouth of a river roaster.
Background technology
At present, in the steel billet of metallurgical steel mill was produced, molten steel flowed out from the pans that fill with molten steel, and crystallisation by cooling becomes steel billet in the molten steel inflow crystallizer.Molten steel is called the mouth of a river from the outlet that pans flow out, and the mouth of a river must keep dry in the production process, as water or steam are arranged on the mouth of a river, is prone to the accident of blasting in the steel billet production.When filling with molten steel, pans wait for that outside production line when reaching the standard grade, the mouth of a river must keep dry.
Referring to Fig. 1, dry for the mouth of a river that keeps pans, traditional exhausting formula roaster is the roaster that adopts the configuration air exhauster, uses the air blast exhausting, guarantees that mouth of a river surrounding air flows fast, thereby keeps the mouth of a river dry.
Exhausting formula roaster must dispose air blast, and equipment cost is high; Simultaneously, owing to be exhausting, be prone to bad air blast of baking when high-temperature gas is flowed through air blast, equipment dependability is poor.
Summary of the invention
The purpose of the utility model provides a kind of air blowing type mouth of a river roaster, and this air blowing type mouth of a river roaster equipment cost is low, and functional reliability is high.
In order to achieve the above object, the air blowing type mouth of a river roaster of the utility model comprises baking body and exhaust column; Exhaust column is installed in the bottom of baking body; It is characterized in that: also comprise inflatable body, inflatable body is made up of gas blow pipe and compressed air generator, and the air inlet of gas blow pipe links to each other with the gas outlet of compressed air generator; The gas outlet of gas blow pipe is installed in the exhaust column, and the gas outlet of gas blow pipe is towards the exhaust column port of export.
Air blowing type mouth of a river roaster is installed in the below, the mouth of a river of pans, because inflatable body has been arranged, and the gas outlet of the gas blow pipe of inflatable body is towards the exhaust column port of export; When compressed air generator is worked; Compressed air forms high velocity air in exhaust column, the direction of air-flow just forms negative pressuren zone towards the exhaust column port of export in exhaust column; The baking body links to each other with exhaust column; Also just form negative pressure in the baking body, the high temperature air around the mouth of a river is constantly sucked, and has kept the mouth of a river of pans dry.
Do not dispose air blast in the roaster of the utility model air blowing type mouth of a river, equipment investment is few, and cost is low; Simultaneously, air blowing type mouth of a river roaster adopts the mode of air blowing exhausting in the course of the work, does not have the high-temperature gas compressed air generator of flowing through, and equipment can not damage with moist because of the high temperature of high temperature gas flow, and equipment dependability is high.
Described air blowing type mouth of a river roaster is characterized in that: compressed air generator is an air compressor.
The air blowing type mouth of a river roaster of the utility model, equipment cost is low, and functional reliability is high.
Description of drawings
Fig. 1 is the structural representation of traditional exhausting formula roaster.
Fig. 2 is the structural representation of the utility model embodiment.
The specific embodiment
The explanation of Fig. 2 mark: baking body 1, exhaust column 2, gas blow pipe 3, the mouth of a river 4 of pans.
Referring to Fig. 2; The embodiment of the utility model air blowing type mouth of a river roaster comprises baking body 1, exhaust column 2 and inflatable body; Exhaust column 2 is installed in the bottom of baking body 1, and inflatable body is made up of gas blow pipe 3 and compressed air generator, and the air inlet of gas blow pipe 3 links to each other with the gas outlet of compressed air generator; The gas outlet of gas blow pipe 3 is installed in the exhaust column 2, and the gas outlet of gas blow pipe 3 is towards exhaust column 2 ports of export.
Air blowing type mouth of a river roaster is installed in 4 belows, the mouth of a river of pans, because inflatable body has been arranged, and the gas outlet of the gas blow pipe 3 of inflatable body is towards exhaust column 2 ports of export; When compressed air generator is worked; Compressed air forms high velocity air in exhaust column 2, the direction of air-flow just forms negative pressuren zone towards exhaust column 2 ports of export in exhaust column 2; Baking body 1 links to each other with exhaust column 2; Also just form negative pressure in the baking body 1, the high temperature air around the mouth of a river is constantly sucked, and has kept the mouth of a river 4 dryings of pans.
Do not dispose air blast in the roaster of the utility model air blowing type mouth of a river, equipment investment is few, and cost is low; Simultaneously, air blowing type mouth of a river roaster adopts the mode of air blowing exhausting in the course of the work, does not have the high-temperature gas compressed air generator of flowing through, and equipment can not damage with moist because of the high temperature of high temperature gas flow, and equipment dependability is high.
In actual the use, the compressed air air feed of gas blow pipe 3 can adopt the workshop compressed air gas source.
The air blowing type mouth of a river roaster of the utility model, equipment cost is low, and functional reliability is high, and applying of it has positive meaning to saving equipment investment cost, assurance equipment operate as normal.
