Abstract
The utility model discloses a convex rotary door pocket type resistor furnace, which belongs to the technical field of heat processing equipment and is formed by a furnace casing, a furnace inner body and a furnace door. The furnace door is in a double-layered insulating structure with a convex refractory brick insulating layer and a refractory fiber insulating layer, the furnace door is fixed on a front face plate of the furnace outer casing via a connector on the right side and leads opening and closing of a furnace cover to be flexible, a handle sleeved with a pressure spring is designed in the middle portion of the left side of the furnace door, and a slant support rod is mounted at the lower left corner of the furnace door which is rotating type with right-side opening. The furnace has the advantages of reasonable design, simple structure, low manufacturing cost, fine insulation performance and electricity saving of about 8% relatively to convention technique.
Description
Technical field
The utility model relates to a kind of convex turn door chamber type electric resistance furnace.
Background technology
The common metal part carries out the resistance heading furnace of normalizing, annealing, quenching and modifier treatment under oxidizing atmosphere, mostly use chamber type electric resistance furnace, the chamber type electric resistance furnace complex structure of conventional art, fire door mechanism is overweight and stopping property is poor, closing with unlimited of fire door realizes by hoisting appliance that all its hoisting appliance is that a cover contains the complicated operating mechanism of a cover such as rope sheave, bearing, wheel shaft, sprocket wheel, chain, counter weight, crank.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned chamber type electric resistance furnace, provides a kind of fire door mechanism to simplify greatly, but protrude at the fire door middle part, and can be airtight protrudingly advance that turn in the stove is opened the door, the chamber type electric resistance furnace reasonable in design of good heat insulating.
For achieving the above object, the utility model adopts following proposal:
The utility model is mainly by furnace shell, furnace lining, heating unit, drop-bottom and fire door are formed, its main points are said fire doors, the fire door shell is welded into by general steel plate, directly heating surface is built into by light fire brick, half of light fire brick length exposed outside the fire door shell, several layers of fire-retardent fiber felt-rug are posted at the heating surface back, outermost is tight compact with the iron plate cap seal, the heating surface refractory insulating layer copies the shape of stove gate to cut into protrusion shape, paste one deck fire-retardent fiber felt-rug around the salient root, fire door is fixed on the front panel of stove outer covering with wearing axle by the web member on right side, bell is opened close flexibly.For preventing fire door overweight left side tenesmus, fire door lower-left end is equipped with inclined support bar, inclined support bar and right side are worn a following extended line and are linked together below retaining plate bottom, the handgrip that is with stage clip has been installed in fire door left end middle part, the handle stem front end is welded with the buting iron hook, rotate handgrip after fastening fire door, in the board slot nose of buting iron hook precession body of heater front, fire door can the fastening fire door.
The utility model is not established worktable, the taking on stove and can use the function that replaces worktable with the contour brandreth car of drop-bottom of workpiece, and the brandreth car also has the advantage of remote handover workpiece.
The utility model compared with prior art owing to saved numerous and diverse fire door hoisting appliance, have simple in structure, reasonable in design, body of heater is in light weight, cost is low, labour intensity is little and the advantage of good heat insulating, the working stage economize on electricity reaches about 8%.
