Fire bars can only be provided with one deck under the stove tube, the fire bars that overturns gradually burns till material to lower floor and discharges, and the material in the stove tube moves down gradually to be fired.For making fire more even, two-layer or two-layer above fire bars is preferably established in the operation of being more convenient for, and material multilayer in the stove tube such as shell is placed, and by preheating successively, heat, fire finished product.Undermost material is fired into process, heating simultaneously fire or preheating on which floor material.When upper materials is turned to down one deck process, material will rearrange mixing again, and it is more even that material is fired.The material that is in stove barrel limit can always not be in the place, limit in the process of moving down, and can not cause place, limit material to burn and give birth to.Can fire finished product from level to level like this, and add material from level to level from stove tube top.
The rotational structure of fire bars can be the various drive mechanisms that fire bars is rotated.Be the most simply and easily with fire bars and the crank that is connected or handle or with the cross-coupled driving lever of fire bars.As long as move crank or handle or driving lever with regard to turning fire bars.Can rotate single fire bars, preferably rotate simultaneously with layer fire bars.So preferably between crank (crank), handle, driving lever, be connected with connecting rod with layer fire bars.When shell rotated, the fire bars of layer overturn simultaneously together.Forward the little direction of width to from the width general orientation between the fire bars, the gap between fire bars is strengthened, make material such as shell down from row between fire bars.Then forward the width general orientation again to, reduce the gap between fire bars, the material that gets off next time with the face that connects.Hand can be directly used in the driving of fire bars rotational structure, as move crank, handle, driving lever etc. with hand, also can add coaxial handwheel, rotates with hand.Can certainly be with electronic, as with electromagnet or motor drives.Fire bars rotational structure more stably preferably adopts the gear of the coaxial connection of fire bars.Gear with layer fire bars is meshing with each other, and perhaps the wheel and rack with layer fire bars meshes.Gear or tooth bar are connected with drives structure, with regard to turning fire bars.Drives structure can be handwheel or motor etc. equally.
The stove tube can be the stove tube of different shape, as cylindrical shape commonly used.But in order to cooperate rotatable fire bars, be convenient to also overturn freely near the fire bars of stove barrel, the stove tube is rectangle preferably, i.e. rectangle stove tube.Just can be made into same size with layer fire bars like this, the processing and fabricating of being more convenient for, also more convenient during turning operation.All fire bars can overturn, and laterally do not have the dead angle at the stove tube.
Owing to adopted technical scheme structure of the present invention, therefore shell burning stove of the present invention can add material gradually from stove tube top, and material moves down gradually or successively, fires the abundant heat exchange of heat with what rise from stove tube bottom, fires and progressively be heated.Reach firing temperature at last and discharge, formed the equipment of material such as continuous firing shell simply and easily.The heat of firing is utilized fully.The material that moves down must stir and go here and there, and is progressively to move down heat exchange to be heated, so each several part heating is more even, can both progressively reaches firing temperature and is discharged from, and the end product quality of firing is than higher and even.Shell burning stove of the present invention is convenient to operation and is burnt till control simultaneously, has reduced labour intensity.
The present invention is further illustrated below in conjunction with the example of accompanying drawing.
Accompanying drawing is represented the structure chart of shell burning stove of the present invention.Fig. 1 is the front view of body of heater, and Fig. 2 is the cutaway view of bowing of cylinder shell burning stove, and Fig. 3 is the vertical view of cylinder shell burning stove, and Fig. 4 is the cutaway view of bowing of square tube shell burning stove.
Example 1,
