A kind of can-type calcine furnace is made up of calcining jar, combustion chamber, heating quirk, air channel, volatilization shunting, flue, feeding system and discharge system, and feeding system is arranged on the top of calcining jar; Bottom at the calcining jar is provided with discharge system; Described can-type calcine furnace includes about two to be arranged and the calcining jar of arranged perpendicular, is provided with the heating quirk in the both sides, front and back of said calcining jar, and the import of heating quirk connects the combustion chamber; Outlet is communicated with flue; Outer periphery at the heating quirk is equipped with the volatilization shunting, and the inlet in volatilization shunting connects the volatile matter outlet that is located at calcining jar top, and outlet is communicated with the heating quirk; Air channel is arranged on the below of heating quirk, is communicated with the volatilization shunting.

Wherein, heating quirk has five layers, and along calcining jar arrangement in a zigzag up and down, air channel has two layers, is arranged above and below along the calcining jar.

Described feeding system comprises hopper and the screw(-type) feeder that is arranged on the calcining jar charging aperture, and discharge system comprises the furnace charge door and is installed in furnace charge cooling jacket and multiple tooth rotation discharge machine outdoors.

The utility model also furnace wall of can-type calcine furnace is provided with and sees fire and thermometer hole.

The can-type calcine furnace of the utility model is not to be the simple cutting to existing four pot types or multipot type calcining furnace body structure, compared with prior art, the utlity model has following advantage:

1, the can-type calcine furnace of the utility model employing combustion chamber simple in structure is a thermal source, and the thermal source of four pot types or multipot type calcining furnace adopts the numerous and diverse regenerator of gas piping and jet for gas and structure to form;

2, the can-type calcine furnace of the utility model only is provided with five layers of heating quirk, and the heat energy utilization rate is higher, and four pot types or multipot type calcining furnace heating quirk are general many in six to eight roads or more than eight roads, and structure is numerous and diverse, and manufacturing cost is very expensive;

3, the can-type calcine furnace fugitive constituent of the utility model is directly through after the preheating of heating quirk periphery secondary; Converge with the air of air channel, get into the heating quirk and heat, simple in structure; The heat energy utilization rate is high; And four pot types of the prior art or multipot type calcining furnace, its preheated air road structure is very complicated, and cost is also very expensive;

4, the can-type calcine furnace design science of the utility model, structure is unique, and cheap, easy to use, the calcining furnace of prior art can't be compared with it.

The can-type calcine furnace of the utility model is simple in structure, and construction cost is low, and burning quality is good; After discharging from a calcining jar top outlet by the volatile matter that decomposites in the raw material; Mix with air, after the preheating of heating quirk, get into the heating quirk, fully burning utilizes; Full furnace thermal efficiency is higher, and the production continuity is strong.Maintenance is less in the utility model production process, and maintenance cost is low, and production efficiency is high.
