Abstract
The utility model discloses a box type infrared electric resistance stove, which is used for devices for heat treating non-ferrous metal and ferrous metal. The existing resistance stove generally has the disadvantages of great heat waste and high energy consumption. The utility model improves the arrangements of a stove body, a stove door lifting mechanism and an electric heating element. The stove body is composed of a stove casing, heat-resisting bricks, a heat-insulating layer which is formed by crushed crude pearlite perlite powder; the stove door lifting mechanism adopts the hand-operated mechanism of a chain driving; the electric heating element is arranged by hang and is parallel with a wall body; thus, the utility model has the advantages of fast heating and little heat waste, and the rate of power save can reach to 30-75 %.
Description
Box ir resistance furnace is ferrous metal and non-ferrous metal Equipment for Heating Processing.
Existing various heat treatment resistance furnace, the furnace insulation poor performance that has, fire door adopts plug-type, and the resistive band suspension is provided with unreasonable, and these all can cause the thermal efficiency to reduce, thus power consumption is big.
The purpose of this utility model is that fire door adopts elevating mechanism by furnace binding is improved, and the hang that resistive band is new and improve heating efficiency reduces energy loss, thus energy savings.
The utility model is by body of heater, burner hearth, fire door, fire door elevating mechanism, burner hearth internal heat generation element constitutes, body of heater has furnace shell 1 and is bonded at alumina silicate fibre carpet veneer 6 on the furnace shell inwall, and burner hearth adopts light weeight alumina brick 7 to be built into, and fills crushed crude pearlite 3 between burner hearth and the furnace shell; Body of wall is provided with hook 4 in the burner hearth, and banded heating 5 hangs on the hook 4, and burner hearth bottom is provided with furnace bottom heating 9 and which is provided with embankment; The fire door elevating mechanism adopts the hand cranking structure of chain drive, power transmission shaft 20 is fixed on upper of furnace body, auxiliary wheel 11 is arranged on the power transmission shaft 20, sprocket wheel 12, gear 17, crank 18 are fixed on the body of heater sidepiece, have balancing weight 19 on the auxiliary wheel 11, track 14 is positioned at 16 two at fire door, and fire door 16 both sides also are provided with fire door and compress handgrip 15.
An independently whole bell is made by the furnace roof portion of the utility model body of heater, adopts alumina silicate dimension dimension plate to laminate, and is middle with the fastening shaping of combing of bar heat resisting steel.Because separate, when burner hearth overhaul or heating replacing, need only extract bell out and get final product with furnace wall.Reached the purpose that saves time, reduces waste of material.
Burner hearth adopts 0.5～1.0 to be built into through light weeight alumina brick, can reduce furnace lining amount of stored heat and the conductive heat loss by furnace lining, has obvious energy-saving effect.
The heating coiling is structure as shown in Figure 2, the band shape that is about to process folding at an angle of 90 after again around, system but be converted into 55 °～75 ° angles by ribbon heater, both sides, fire door place.The ribbon heater be suspended on the hook 4 on metope equality, be with the brushing infra-red paint.The hook 4 that hangs the ribbon heater is divided into upper and lower hook, and last hook is consolidated extremely on inboard wall of burner hearth, and lower draw-bar can form 90 ° of rotations in inboard wall of burner hearth brick groove.Provide convenience for the heating mounting or dismounting like this.
Fire door is to adopt steel plate to be welded into shell, in the alumina silicate fiber felt that laminates shaping is housed, and protrude in the fire door, be with one deck asbestos trim ring outward, double-layer sealing structure has reduced furnace temperature and has scattered and disappeared.
The utility model has the advantages that the body of heater volume is little, in light weight, quick heating, few, the good heat insulating of heat loss, power saving rate can reach 30～75%, is the higher resistance furnace of present power saving rate.
Fig. 1 is the utility model fire door lifting structure schematic diagram.
Fig. 2 is ribbon heater coiling figure.
Fig. 3 is body of heater, burner hearth schematic diagram.
Embodiment: specification the 5th part has been described an embodiment of the present utility model in detail.
