Abstract
The utility model discloses a tunnel type continuous fritting furnace, which comprises a furnace casing, a furnace chamber, a flue, and a conveying belt for burnt products. The inside of the furnace chamber is divided into a combustion chamber and a finished chamber through a fire separation wall, and the combustion chamber is positioned above the finished chamber. The conveying belt for burnt products is positioned below the finished chamber, and the end of the furnace chamber corresponding to the combustion chamber is provided with a fuel nozzle. The flue is arranged on the furnace casing positioned above the combustion chamber. In addition, the upper part of the combustion chamber is provided with an arch wall to form the meridian passage well structure. The utility model has the advantage that the service life of the conveying belt can be prolonged and the combustion of the fuel is thorough.
Description
The utility model relates to a kind of kiln that is used for enamel, ceramic post sintering and glass processing, and particularly relating to a kind of is the tunnel type continuous sintering kiln of heating source with fuel oil, combustion gas.
Existing tunnel type continuous sintering kiln comprises kiln housing and burner hearth mostly, burner hearth inside is divided into the combustion chamber and burns till the chamber by flame partition wall, wherein, the combustion chamber is positioned at the below or the both sides of burning till the chamber, end in the combustion chamber is provided with fuel nozzle, this nozzle is connected with fuel delivery means, its defective is: conveyer belt of (1) burnt product and combustion chamber direct neighbor, the residing position of conveyer belt temperature is higher, influence the service life of conveyer belt, therefore, require conveyer belt must have great high-temperature resistant; (2) imperfect combustion gas upwards accumulates in easily and burns till the chamber in the fuel, makes the chamber of burning till reducing atmosphere occur, influences the quality of burning till of goods.
The purpose of this utility model provides and a kind ofly prolongs conveyer belt service life, makes fuel combustion tunnel type continuous sintering more completely kiln.
The purpose of this utility model realizes by following technical measures: a kind of tunnel type continuous sintering kiln, it comprises kiln housing, burner hearth, flue and burnt product conveyer belt, burner hearth inside is divided into the combustion chamber and burns till the chamber by flame partition wall, it is characterized in that: described combustion chamber is positioned at the top of burning till the chamber, the burnt product conveyer belt is positioned at the bottom of burning till the chamber, the burner hearth end is provided with fuel nozzle corresponding to the position of combustion chamber, and described flue is arranged on the kiln housing of top, combustion chamber.
As further improvement of the utility model, top in the combustion chamber, be provided with the arch wall, courtyard between this arch wall and the kiln housing above it, forming, arch wall below is the combustion chamber, courtyard communicates with the combustion chamber in the furnace end away from fuel nozzle in described, and flue is arranged near on the kiln housing of fuel nozzle, communicates with middle courtyard.
The material of the flame partition wall described in the utility model can be heat conductivility better heat-resisting materials such as silicon-carbon plate or heat resisting steel.Utilize the thermal conductivity and the heat radiation of flame partition wall, heat energy is introduced from the combustion chamber burnt till the chamber, with the effect that realizes that muffle is heated.
The utility model can be provided with fuel nozzle respectively in two ends of burner hearth, and flue is arranged on the kiln housing at kiln middle part, to obtain bigger high-temperature region.
The big deficiency of variations in temperature also can be provided with the resistance wire heater in the high-temperature region of kiln, in order to compensates when heating in order to remedy fuel.
The utility model compared with prior art has the following advantages: (1) is because the combustion chamber in the utility model is positioned at the top of burning till the chamber, the later residual gas of fuel combustion can burn in the combustion chamber after being heated upwards once more, therefore, the burning of fuel is more thorough.(2) because the burnt product conveyer belt in the utility model away from the combustion chamber, can avoid conveyer belt because of too high caused oxidation or the distortion etc. of being heated, obtain its service life prolonging; On the other hand, because the high temperature resistant requirement of conveyer belt material is reduced, the cost of conveyer belt also further reduces.(3), in the courtyard, reduced heat effectively and scattered and disappeared, improved the heat-insulating property of combustion chamber in the waste heat of combustion chamber can being introduced if the utility model is provided with middle courtyard, energy-conservation province consumption, simultaneously, also can reduce kiln environment temperature on every side, improve operating personnel's working environment.
The utility model is described in further detail below in conjunction with drawings and Examples.
