Description
Technical field
Electric furnace technical field is the utility model is related to, specifically, more particularly to a kind of furnace body of electric furnace.
Background technology
Existing furnace structure only has outer barrel, and it is more to contact the pressure-containing parts quantity of high temperature, so as to add high temperature resistant stainless steel
Dosage, increases considerably equipment investment, while improves outside wall temperature, makes radiation loss more, the safe operation of equipment
Can be poor.
Utility model content
The technical problem to be solved by the utility model is to for above-mentioned deficiency of the prior art, disclose a kind of electricity
The furnace body of heating furnace, its former furnace structure are divided into outer pressure carriage and not subjected to pressure inner cylinder two parts, reduce the compression of contact high temperature
Number of components, so as to reduce high temperature resistant stainless steel dosage, is greatly reduced equipment investment, while reduces outside wall temperature,
Make radiation loss less, the safe running performance of equipment is also more preferable.
Technical solution is used by the utility model solves its technical problem：A kind of furnace body of electric furnace, including skirt
Seat, low head, blowdown connection, outer barrel, electrical bar, air inlet tube, check washer, nut, tube sheet flange, outgoing gas connection tube, connection
Flange, screw, baffle plate and inner cylinder；The low head is fixedly mounted on the bottom surface of outer barrel, and the low head is installed on skirt
On, the blowdown connection is installed in the centre bore of low head, and the air inlet tube is installed on the right flank of outer barrel, the company
Acting flange welded and installed is on outer barrel and the either flush of connecting flange top surface and outer barrel, the tube sheet flange pass through locking pad
Piece, nut and screw are fixedly mounted on the top surface of connecting flange, and the outgoing gas connection tube is installed in the centre bore of tube sheet flange,
The inner tube installation is in outer barrel and inner cylinder top surface is installed on the bottom surface of tube sheet flange, and the electrically heated rod upper end is installed on pipe
In the mounting hole of plate flange, the electrically heated rod lower end is installed in the mounting hole of inner cylinder, and the baffle plate is installed on electrical heating
On rod and baffle plate is located in inner cylinder.
As a kind of preferred embodiment of the utility model, the axis of the inner cylinder is overlapped with the axis of outer barrel.
As a kind of preferred embodiment of the utility model, the outer barrel and inner cylinder all use 316 stainless steel systems
Form.
As a kind of preferred embodiment of the utility model, pacify between the tube sheet flange bottom and connecting flange top surface
Equipped with sealing ring.
Utility model works flow：The relatively low tangential admission of temperature first streams the annular space between inner/outer tube, makes outside pressure-bearing
Cylinder obtains low-temperature protection, and 20 DEG C or so are risen to gas temperature during annular space bottom, and then back enters inner cylinder by electrical heating, rises to finger
Drawn after mark temperature by top outgoing gas connection tube.It can be seen from the above that really the pressure-containing parts of contact high temperature only remains tube sheet flange.
The utility model has the following advantages compared with prior art：Former furnace structure is divided into outer pressure carriage and not subjected to pressure
Cylinder two parts, reduce the pressure-containing parts quantity of contact high temperature, so as to reduce high temperature resistant stainless steel dosage, make equipment investment big
Amplitude is reduced, while reduces outside wall temperature, makes radiation loss less, the safe running performance of equipment is also more preferable.
