Description

Efficient natural gas trolley heating furnace
Technical field
The present invention relates to a kind of industrial furnace, in particular it relates to a kind of natural gas trolley heating furnace.
Background technology
Existing natural gas trolley heating furnace burner hearth is connected with smoke evacuation system by exhanst gas outlet, burner hearth bottom surface is located at the furnace roller for transporting material, furnace roller is it is generally required to support and transport heavier material, and operating temperature is at about 1000 DEG C, intensity and the anti-wear performance of furnace roller are relatively big because high temperature impact reduces, and particularly the bearing at furnace roller two ends is because being affected by high temperature and being easily damaged, and the service life of bearing shortens, the most even needing stops production changes bearing, has influence on normal production;On the other hand, the sealing device between chassis and body of heater is usually and is made up of the seal being fixedly installed in chassis and body of heater side respectively, and between seal, gap is relatively big, and sealing effectiveness is undesirable, and natural gas trolley heating furnace heat insulation effect is bad, and fuel consumption is big.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose one and there is high temperature resistant, high intensity furnace roller, and burner hearth good airproof performance, the efficient natural gas trolley heating furnace that fuel consumption is low.
The present invention is achieved through the following technical solutions technical goal.
A kind of efficient natural gas trolley heating furnace, including body of heater, roll body, butterfly valve controller, driven journal and chassis;It thes improvement is that: be provided with sealing structure between described body of heater and chassis side, and furnace sealing structure is connected with body of heater and fixing, including machinery push-pull device at fixed and sealed knife by sealing supporter;Chassis seals structure and includes being located at chassis side C-shaped sealing block;Described roll body uses water-cooled cooling mode to cool down: roll body one end spindle nose is water-cooled side shaft head, the other end is driven journal, water-cooled side shaft head and roll body are provided with the centre bore being interconnected, driven journal is provided with blind hole and the centre bore with roll body and water-cooled side shaft head is connected, roll body surface is provided with refractory material, is respectively equipped with annular convex near the position at two ends.
As further improvement project, described machinery push-pull device at fixed is connected with sealed knife and C-shaped configuration sealed knife can be promoted to move back and forth, and is provided with soft high temperature sealing material in sealed knife, sealing block.
As further improvement project, described machinery push-pull device at fixed promotes sealed knife to be mutually fitting to connection with sealing block.
As further improvement project, in the burner hearth of described body of heater, it is provided with the thermocouple being connected with butterfly valve controller and pressure transducer.
As further improvement project, described roll body is made up of internal layer axle body and outer refractory.
The present invention compared with prior art, has the positive effect that:
1, using mechanically-sealing apparatus to seal between the body of heater and chassis of heating furnace, convenient operation and control, the sealing effectiveness of heating furnace is preferable, and does not affect chassis turnover burner hearth, and energy consumption is low, high insulating effect, and flexible operation is steady.
2, roll body uses water-cooled cooling mode cooling, the outer layer of roll body uses pouring type to arrange refractory material, furnace roller is made to have higher intensity and anti-wear performance, bigger weight can be born, heat resisting temperature reaches 1350 DEG C, and the high temperature impact on roll body bearings at both ends can be reduced, notable prolongation roll body and the service life of bearing.
3, it is provided with in burner hearth and controls thermocouple and the pressure transducer that device is connected, it is possible to accurately controlling the temperature and pressure in burner hearth by controlling the switch of butterfly valve, make the temperature and pressure in burner hearth more equalize, substantially reduce gas fuel consumption.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
Efficient natural gas trolley heating furnace, including body of heater, roll body, butterfly valve controller, driven journal and chassis;Being provided with sealing structure between body of heater and chassis side, furnace sealing structure is connected with body of heater and fixing by sealing supporter, and furnace sealing structure includes machinery push-pull device at fixed and sealed knife, and chassis seals structure and includes being located at chassis side C-shaped sealing block;Roll body uses water-cooled cooling mode to cool down: roll body one end spindle nose is water-cooled side shaft head, the other end is driven journal, water-cooled side shaft head and roll body are provided with the centre bore being interconnected, driven journal is provided with blind hole and the centre bore with roll body and water-cooled side shaft head is connected, roll body surface is provided with refractory material, is respectively equipped with annular convex near the position at two ends.
Machinery push-pull device at fixed is connected with sealed knife and C-shaped configuration sealed knife can be promoted to move back and forth, and is provided with soft high temperature sealing material in sealed knife, sealing block.
Machinery push-pull device at fixed promotes sealed knife to be mutually fitting to connection with sealing block.
