Three, summary of the invention
The purpose of this utility model is to provide a kind of polygonal cross-section boiler tube continous way rotary furnace at the weak point that above-mentioned rotary kiln exists.
The utility model technology compared with prior art, its advantage and characteristics are: powder material is produced more fully and completely stir and mix, produce particle conversion more completely and gas and discharge; 2, its complete hermetically-sealed construction can be realized atmosphere protection and atmosphere control completely; 3, reasonably the combination of heating mode and heating element heater can reach better energy-saving effect, has reduced power consumption, has improved hot service efficiency; 4, material, structure, the design of equipment integral body are more perfect, have guaranteed stability and the reliability of equipment in the middle of using effectively.
The purpose of this utility model is to realize like this: it comprises feed system, sealing device, gas extraction system, revolving body, the control system that adds heat run, discharge system, gas piping system, boiler tube, temp measuring system, refractory material, furnace body frame and outward appearance, light-duty fireproof modules, transmission system constitutes, feed system passes through control valve, spiral feeder is connected in revolving body, be fixed with the control system that adds heat run at revolving body, temp measuring system, refractory material, light-duty fireproof modules, revolving body places on the frame, discharge system, be located at the afterbody of burner, revolving body is a polyhedron, the cross section of boiler tube is the cylinder of one group of equilateral polygon, be provided with a plate washer between the cooling area of boiler tube and the high-temperature region, at the cylindrical shell two ends of revolving body each cover of wall device that shakes is set, the cross section of described boiler tube is one group of equilateral polygon, its polygon is the polygon greater than 3, and the boiler tube two ends of revolving body are provided with sealing device.Charging, discharge system adopt stainless steel screw(-type) feeder, and the feed motor is mechanical inorganic speed change, and is manually adjustable, and the stainless steel hopper is established on top, are with electronic shake wall device.Add that heating element heater is the METAL HEATING PROCESS silk in the control system of heat run, adopt the circular furnace lining of heater strip half inserted overall vacuum cast lightweight.
The utility model has adopted special polyhedron rotary pipe type structure, polyhedral each plane forms angle and (forms 120 degree angles between such as each plane of hexahedron when welding, form 90 degree angles etc. between each plane of tetrahedron), powder material can be broken up and be formed the particle displacement naturally when rotational slide slips over angle, powder material is produced when being heated calcining fully and fully mix, and reach full and uniform reaction and thing phase transformation; In conjunction with the waveform and the straight plate shape scraper plate of polyhedron boiler tube inner surface setting, when rotating, revolving body can make powder material raise the step-by-step movement of spreading and move doing parabolic path with axis direction.
For this polyhedron rotary pipe type kiln, powder material is achieved in that at the running of this section operation powder material at first is loaded in the kiln hood charging feed bin, fall to spiral feeder and be transported in the polyhedron boiler tube by by-pass valve control and pipeline by spiral feeder, establish sealing device between its burner device and the polyhedron swinging boiler tube, because the whole boiler tube of polyhedron can be regulated with horizontal direction and form certain inclination angle, after material enters into the polyhedron boiler tube, rotation (the big I of rotating speed is adjusted according to actual conditions) along with the polyhedron boiler tube, powder material is in the parabolic path motion while of doing the section direction and do slowly moving of axis direction, respectively by each temperature-controlled area in the boiler tube, the temperature of each temperature-controlled area can be arranged to identical or differently burn till with the control that reaches the uniform temperature curve according to powder product self arts demand in the middle of the process that moves.Finish burn till after, material enter boiler tube afterbody and the cooling, the powder after the cooling exports to outside the stove from the discharge bucket of body of heater afterbody.
