Abstract
The utility model discloses a tail gas forced-discharge-type atmosphere furnace which comprises a furnace body, a furnace door and a furnace chamber, and is characterized in that a fluorosilicone sealing ring is arranged between the furnace door and the furnace body; a water cooling circulating system is arranged on the furnace door; the furnace chamber is coated with a silicon carbide refractory slab; a heating element is arranged below the silicon carbide refractory slab; an air inlet passage is arranged at the top of the furnace chamber; a preheating cavity is arranged on the air inlet passage; a heating device is arranged inside the preheating cavity; an exhaust opening is formed in the bottom of the furnace chamber; a tail gas treatment device is connected to the exhaust opening and is composed of a coil pipe, an air exhauster arranged on the coil pipe, and a heating element arranged inside the coil pipe. The tail gas forced-discharge-type atmosphere furnace is mainly used for sintering materials which generate organic gas during sintering.
Description
Technical field
The utility model belongs to atmosphere furnace field.
Background technology
Atmosphere furnace need to pass into protective gas when heating, therefore the air-tightness of whole body of heater is had relatively high expectations.Existing atmosphere furnace adopts the sealing of conventional seals circle, is easy to aging gas leakage.Existing atmosphere furnace does not have preheating device, when passing into protective gas, can cause temperature in stove to reduce.
While using atmosphere furnace, material can produce a lot of organic gas, and existing vent gas treatment is all generally that tail gas is passed in water, but this class gas is easy to condense in gas exhaust piping, causes security incident.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide the forced-ventilated atmosphere furnace of a kind of tail gas, solves the existing atmosphere furnace sealing problem that easily aging and logical protective gas does not have preheating to cause temperature to reduce.
The technical solution of the utility model is: the forced-ventilated atmosphere furnace of a kind of tail gas, comprise body of heater, fire door and burner hearth, it is characterized in that, between described fire door and body of heater, be provided with fluorosioloxane rubber sealing ring, described fire door is provided with water-cooling circulating system, in described burner hearth, be coated with silicon carbide deck, silicon carbide deck is arranged with heating element heater; Roof of the furnace is provided with inlet channel, on described inlet channel, is provided with preheating cavity, in described preheating cavity, is provided with heater; Burner hearth bottom is provided with exhaust outlet, connects an exhaust gas processing device on described exhaust outlet, described exhaust gas processing device by coiled pipe, be arranged on the air exhauster on coiled pipe and the heating element heater that is arranged in coiled pipe forms.
The utility model compared with prior art tool has the following advantages:
Between fire door of the present utility model and body of heater, adopt fluorosioloxane rubber sealing ring, because fluorosioloxane rubber has very high heat resistance, can well guarantee air-tightness.On fire door, be provided with water-cooling circulating system, can effectively reduce the temperature of fluorosioloxane rubber sealing ring, extend the life-span of silicone rubber O-ring.On heating element heater, be provided with silicon carbide deck, in heating process, through silicon carbide deck, conduct more uniform temperature.On inlet channel, be provided with preheating cavity, can carry out preheating to gas.Exhaust gas processing device adopts forced-ventilated, and in coiled pipe, is provided with heating element heater, and organic gas can fully burn and exhaust under the effect of heating element heater.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, Reference numeral is: 1-body of heater, 2-fire door, 3-burner hearth, 4-fluorosioloxane rubber sealing ring, 5-inlet channel, 6-preheating cavity, 7-coiled pipe, 8-air exhauster, 9-heating element heater.
The specific embodiment
Embodiment
As shown in Figure 1, the forced-ventilated atmosphere furnace of a kind of tail gas, comprises body of heater 1, fire door 2 and burner hearth 3.Between described fire door 2 and body of heater 1, be provided with fluorosioloxane rubber sealing ring 4, described fire door 2 is provided with water-cooling circulating system.Water-cooling circulating system consists of the circulation pipe, cistern and the circulating pump that are arranged on fire door 2.In described burner hearth 3, be coated with silicon carbide deck, silicon carbide deck is arranged with heating element heater.In heating process, through silicon carbide deck, conduct more uniform temperature.Burner hearth 3 tops are provided with inlet channel 5, on described inlet channel 5, are provided with preheating cavity 6, in described preheating cavity 6, are provided with heater; Heater adopts spiral helicine resistance wire, when gas passes through, just can carry out preheating to gas.Burner hearth 3 bottoms are provided with exhaust outlet, connect an exhaust gas processing device on described exhaust outlet.Described exhaust gas processing device by coiled pipe 7, be arranged on the air exhauster 8 on coiled pipe 7 and the heating element heater 9 that is arranged in coiled pipe 7 forms.Tail gas burns and exhausts in coiled pipe 7 under the effect of heating element heater 9, can prevent that tail gas from condensing in pipeline.
