Description
Technical field
The present invention relates to a kind of titanium white calcination rotary kiln, belong to Machining Technology field.
Background technology
Titanium dioxide is a kind of white pigment of high-quality, has excellent physics, chemistry, optics and pigment performance, is widely used in the industries such as coating, plastics, papermaking, rubber, chemical fibre.Calcining is the process that hydrated titanium dioxide (metatitanic acid) is transformed into titanium dioxide, this process mainly removes moisture in hydrated titanium dioxide and sulphur trioxide, make titanium dioxide be transformed into required crystal formation simultaneously, and show the basic pigment performance of titanium white.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of titanium white calcination rotary kiln.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of titanium white calcination rotary kiln, comprising: kiln body, kiln tail, kiln hood, support roller, transmitting gear; Drive the revolution of kiln body mobile by support roller and transmitting gear bottom kiln body;
Kiln tail is outside equipped with feed bin, and feed bin is connected with kiln body by tremie pipe;
Kiln hood place is provided with burner, and burner is connected with combustion air with fuel;
Be provided with discharge gate bottom described kiln hood, described discharge gate is connected with Raymond mill.
Described titanium white calcination rotary kiln, is characterized in that: described kiln tail place is provided with ash bin, and the air outlet of ash bin is communicated with exhaust gas purification system.
Preferably, described titanium white calcination rotary kiln, is characterized in that: also comprise bar grid, and described discharge gate place is also provided with bar grid.
Described titanium white calcination rotary kiln, is characterized in that: described kiln body inwall is provided with refractory materials.
Preferably, described titanium white calcination rotary kiln, is characterized in that: the diameter of described kiln body is 1.0-4.2m.
Preferably, described titanium white calcination rotary kiln, is characterized in that: the length of described kiln body and the ratio of diameter are 12:1-20:1.
Beneficial effect: titanium white calcination rotary kiln provided by the invention, through the metatitanic acid slurry of Ficus caricaL, delivers to then squeezing in rotary kiln with overstocked pump of calcination process and calcines.Fuel and combustion air enter kiln by lower kiln hood end, the high-temperature gas produced through burning moves to kiln wake flow from kiln hood, adverse current operation has been become with metatitanic acid slurry, metatitanic acid is sent to kiln hood from kiln tail like this, in the process that temperature raises gradually, complete a series of physicochemical change, and form the titanium dioxide product of certain crystal formation.Titanium dioxide falls into drum cooler through kiln hood tremie pipe.Throughput is large, and calcine effective, structure is simple, safe and reliable.
