Abstract
The utility model discloses an atmosphere furnace which comprises a furnace body, a furnace door and a furnace hearth. The atmosphere furnace is characterized in that a fluorinated silicone rubber sealing ring is arranged between the furnace door and the furnace body; the furnace door is provided with a water cooling circulation system; a heating element is arranged in the furnace hearth, and is provided with a silicon carbide shelf board; a gas inlet channel is formed at the top of the furnace hearth, and is provided with a preheating cavity; and a heating device is arranged in the preheating cavity. The atmosphere furnace of the utility model adopts the fluorinated silicone rubber sealing ring between the furnace door and the furnace body; and as fluorinated silicone rubber is higher in heat resistance, the air tightness is preferably guaranteed. The water cooling circulation system is arranged on the furnace door, so that the temperature of the fluorinated silicone rubber sealing ring can be effectively reduced, and the service life of the fluorinated silicone rubber sealing ring is prolonged. The silicon carbide shelf board is arranged on the heating element, and the heating process is conducted by the silicon carbide shelf board, so that the temperature is evener. The gas inlet channel is provided with the preheating cavity, so that gas can be preheated.
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.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of atmosphere furnace, 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: a kind of atmosphere furnace, 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, is provided with heating element heater, on described heating element heater, be provided with silicon carbide deck, 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.
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.
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.
The specific embodiment
Embodiment
As shown in Figure 1, a kind of atmosphere furnace, 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 provided with heating element heater, on described heating element heater, be provided with silicon carbide deck, in heating process, through silicon carbide deck, conduct more uniform temperature.
