Abstract

The utility model relates to a changeable energy saving shaft like electric resistance furnace with a double power chamber. A heat preservation sealing ring is arranged in the double power chamber and divides the double power chamber into two temperature control zones with different powers. The furnace bottom is provided with a height adjustable screw rod which can lift the furnace bottom to connect with the heat preservation sealing ring and divide the double power chamber. Thus, the utility model can process slenderness type workpieces and minor axis type workpieces, which can save electric energy, improve efficiency and reduce production cost. The utility model is especially suitable for the production and processing of medium and small-sized enterprises.

Description

The variable energy-conservation well formula resistance furnace of two power burner hearths

The utility model relates to a kind of industrial heat treatment furnace equipment.

At present, the electric furnace that each electric furnace factory of China produces has the electric furnace of various rated power and the electric furnace of the plurality of specifications burner hearth that adapts, to the large enterprise heat treatment department different furnace equipments can be arranged, but to the part medium-sized and small enterprises, be subjected to fund limitation in heat treated investment, when heat-treatment furnace is purchased in decision-making, purchase that power is big, can handle, major axis also can be handled by smallclothes for darker the reaching of burner hearth, even task is anxious sometimes, not enough batch also wants blow-on to handle, can cause equipment, energy significant wastage, strengthen product cost, lower efficiency.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, thereby a kind of variable energy-conservation well formula resistance furnace of two power burner hearths that can satisfy the large and small batch process of inhomogeneity workpiece such as major and minor axis simultaneously is provided.

The purpose of this utility model realizes in the following way:

This resistance furnace is by furnace shell (1), variable burner hearth (3), heating element heater (4), bell (5), electric oil pump (6) and oil cylinder (7) are formed, wherein: be provided with thermal-insulating sealing ring (2) in the variable burner hearth (3), burner hearth is divided into different temperature controlled region up and down, additional furnace bottom supporting base (8) is provided with furnace bottom (10) in the burner hearth, have adjustable height leading screw (9) on the furnace bottom (10), with additional furnace bottom carrier base (8) by being threaded, furnace bottom (10) has lifting adjusting process hole, have insulation stifled (12) on the hole, stifled (12) center of insulation has lifting suspension ring (13), has heat-insulation layer (11) all around.

When the processing long-axle workpieces, can take out additional furnace bottom and heat-treat; When processing during stub member, furnace bottom can be raise by the adjustable height leading screw, engage being incubated cipher ring (2) in furnace bottom upper surface and the burner hearth, can carry out stub member or small lot batch manufacture.

The utility model compared with prior art has following advantage:

Because burner hearth is divided into different temperature controlled region, size is Height Adjustable, power is various, so both can process long-axle workpieces, can process minor axis class workpiece again, big small lot all can satisfy, effectively utilize power, saved the energy, prolonged the burner hearth life-span, be specially adapted to the production and processing of medium-sized and small enterprises multi-varieties and small-batch, product cost reduces greatly.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is overall structure figure of the present utility model.

Fig. 2 is bottom construction figure.

The complete dark 1.5M of burner hearth, be divided into two temperature controlled region, with thermal-insulating sealing ring (2) is the boundary, top power is 30 kilowatts, bottom power is 40 kilowatts, and integral body is 70 kilowatts, processing long-axle workpieces (within the 1.5M), handle with whole stove, when Workpiece length is less than 0.5M, use upper furnace, power is 30 kilowatts, the burner hearth programming rate is very fast, only take out furnace bottom insulation stifled (12),, use the specific purpose tool rotating threaded shaft with the ring shaped slot of special hanger suspension clamp heat resisting steel furnace bottom, adjust height and burner hearth seal ring seal, insulation stifled (12) is installed again can piece installing production.

Claims

1. two variable energy-conservation well formula resistance furnace of power burner hearth, by furnace shell (1), variable burner hearth (3), heating element heater (4), bell (5), electric oil pump (6) and oil cylinder (7) are formed, it is characterized in that: be provided with thermal-insulating sealing ring (2) in the variable burner hearth (3), burner hearth is divided into different temperature controlled region up and down, additional furnace bottom supporting base (8) is provided with furnace bottom (10) in the burner hearth, have adjustable height leading screw (9) on the furnace bottom (10), with additional furnace bottom carrier base (8) by being threaded, furnace bottom (10) has lifting adjusting process hole, have insulation stifled (12) on the hole, stifled (12) center of insulation has lifting suspension ring (13), has heat-insulation layer (11) all around.
