Abstract
A box-type electric resistance furnace of the utility model belongs to the technical field of heat treatment heating furnace. The utility model is composed of a furnace body, a furnace door, a furnace door lifting mechanism, a heating resistance wire arranged in the furnace body, a heat-insulating material layer and a trolley which can move along the track. The utility model has the advantages of light furnace door, tight seal of the furnace door and the furnace body, small heat dissipation and high heat efficiency. The utility model is characterized in that the furnace door is steel plate door with ribs and whose interior is provided with the heat-insulating layer of the aluminium silicate fibre in tight filling way; the moving mechanism in the furnace door lifting mechanism is formed by a guide wheel with a concave groove and an arc groove in matching way, and the moving mechanism promote the furnace door to move closely toward the furnace body and to be lifted stably when the furnace door falls to the bottom position. The furnace has favorable effect on the mould housing calcination of the precision casting.
Description
The utility model is a kind of novel chamber type electric resistance furnace, belongs to heat treatment, heating furnace technical field.
Existing chamber type electric resistance furnace is by resistive heater that is provided with in furnace base, body of heater, fire door, fire door elevating mechanism, the body of heater and insulation material and can be formed along the dolly that guide rail moves.Described fire door generally is made of with refractory brick ironcasting firedoor frame and its inboard block, so very heavy.The elevating mechanism of fire door is made up of two pairs of sprocket wheels and chain, is driven by the motor and the reducing gear thereof that place body of heater to push up, and by the chain that places on the fire door, fire door is moved up and down.Because this kind fire door elevating mechanism is to move up and down, and must leave certain clearance between fire door and body of heater, although adopted some mechanisms, makes its gap less, also remain furnace heat and distribute part, so the insulation of stove is relatively poor.
The purpose of this utility model is to design a kind of chamber type electric resistance furnace that in light weight, good heat preservation performance energy and body of heater are close to the fire door of sealing that has, and to improve the sealing of stove, reduces the heat loss of batch-type furnace, improves the thermal efficiency of stove, saves the energy.
Of the present utility modelly be characterised in that described fire door is made up of the alumina silicate fibre insulation material of the steel plate fire door that has muscle and its inboard close packed, described fire door elevating mechanism is one to have to body of heater and move the steadily elevating mechanism of lifting, two guide wheels that it respectively is provided with by the fire door both sides and be arranged at channled rail that the fire door both sides has the groove that turns round to the body of heater side and a deep-slotted chip breaker and match and form, groove is located on the guide pass parallel with fire door, deep-slotted chip breaker be located on the guide rail with the perpendicular face of groove place face on.
The utility model can be welded into and clog good heat insulating, very light in weight within it, is convenient to be processed into the heat-insulation layer of the alumina silicate fibre of different shape because of fire door with sheet metal, so fire door is light, and heat-insulating property is fine; The steel plate inboard of fire door is welded with rib, so that fire door has enough intensity.Be provided with two bends that turn round to the body of heater side (groove) on the guide rail that the utility model is provided with in the fire door both sides, guide wheel when they make fire door drop near extreme lower position on the fire door enters bend, this moment, the fire door limit descended, and was close to body of heater when making fire door drop to lowest order thereby the edge guide rail moves to body of heater; And when fire door rises,, can not outwards prize when it rises fire door, but reposefully vertically upward because of one of them bend is positioned on the fire door vertical direction guide pass.The utility model is because of the good seal of fire door and body of heater, and the own good heat insulation of fire door in addition is so heat is difficult for distributing the thermal efficiency height of stove, and the fire door lifting is steady.
Embodiment
Fig. 1 is this chamber type electric resistance furnace structure principle chart
Fig. 2 is the side view of Fig. 1
Fig. 3 is the structure principle chart of fire door elevation and subsidence mechanical
Fig. 4 is the structure principle chart of fire door
Fig. 5 is the side diagrammatic sketch of fire door guide rail
1 is body of heater among the figure, and 2 is the body of heater inner thermal insulating layer, and 3 is resistive heater, and 4 is furnace base, 5 is fire door, and 6 is the fire door elevating mechanism, and 7 is dolly, and 8,9 is guide rail, 10,11 is guide wheel A, B, and 12,13 is guide wheel C, D, and 14 is bolt, 15 is rib, and 16 is alumina silicate fibre, and 17,18 is groove, 19,20 is deep-slotted chip breaker, and 21 is motor, and 22 is reducing gear, 23,24 is sprocket wheel, and 25,26 is chain, 27 axles for the dress sprocket wheel.
Fire door in the present embodiment is to be welded into a type door (5) earlier by steel plate as shown in Figure 4, the intensity of four ribs bar (15) with reinforced door of burn-oning in the door inboard then.Adopt alumina silicate fibre insulation material (16) to insert the inboard of fire door again, the heat-insulating property in the stove is just improved greatly.When filling out the shop alumina silicate fibre, can cut according to its difformity, size, employing multilayer alumina silicate fibre tiles, stack, wears with bolt (14) to string, compress, and clogs in the fire door inboard, and bolt (14) can be welded on the fire door steel plate, and it is fixed.
Fire door elevating mechanism in the present embodiment is to drive the axle (27) that is installed in furnace roof by motor (21) and reducing gear (22) thereof as seen from the figure, rotate thereupon two sprocket wheels (23), (24) on the axle, and two chains (25), (26) that drive on these two sprocket wheels move up and down, because fire door links to each other with chain, thereby is just risen in tow or descended by it.Both sides at fire door (5) are provided with (8), (9) two channled rails, lower end on the guide rail face parallel with fire door is provided with a groove (17), (18), lower end on the perpendicular guide pass of face is provided with an arc groove (19) therewith, (20), guide wheel on fire door (10), (11) respectively along guide rail (8), (9) slide to groove (17) under, (18) time, guide wheel (12) on the fire door (5), (13) also along deep-slotted chip breaker (19), (20) steadily move to the inside on downslide limit in limit, be close to body of heater (1) until fire door (5), because the alumina silicate fibre heat-insulation layer is very smooth, it and body of heater can be close to, when fire door rises, because deep-slotted chip breaker (19), (20) restriction can only move then it outward earlier and rises vertically upward reposefully.Therefore it is fine that the utility model can make fire door and furnace sealing, the good heat insulating that stove is interior, and the fire door lifting is steady.
This shows that fire door corrective measure of the present utility model improves the hot property of chamber type electric resistance furnace greatly, has saved electric energy, has improved labor productivity. The utility model gives adding for the precise casting mould shell roasting to be pined for, and obtains good effect.
