Abstract
The utility model relates to an inorganic pigment atomizing dryer which comprises a barrel body and has the innovation point that a tapered hopper is arranged at the bottom of the barrel body, a hot air distributor is arranged at the top of the barrel body, an atomizer with an outlet located at the central axis of the tapered hopper and having upward atomizing direction is arranged on the side wall of the tapered hopper, a waste gas outlet is arranged on the side wall of the bottom of the tapered hopper, and a star-shaped discharge valve is arranged at the bottom end of the tapered hopper. A ferric oxide suspension is atomized through the atomizer and sprays outwards, hot air spirally and evenly enters the barrel body through the hot air distributor and is in contact with the atomized ferric oxide suspension, suspension droplets are in contact with the high-temperature hot air so that water quickly evaporates and become a dry product within short time, and ferric oxide particles are formed and converged at the bottom of the tapered hopper and are discharged through the star-shaped discharge valve. The spraying direction of the ferric oxide droplets is upward, the contact time between ferric oxide droplets and the hot air can be prolonged, and the drying effect is improved.
Description
Technical field
The utility model relates to a kind of inorganic pigment spray dryer, the inorganic pigment spray dryer that particularly a kind of drying effect is good.
Background technology
Pigment divides from chemical composition; Can be divided into two big types of inorganic pigment and organic pigments; Iron oxide is a kind of important inorganic pigment; When the streamlined that adopts wet method to carry out the iron oxides inorganic pigment is produced, need the iron oxide suspension that the previous stage reaction makes be carried out drying, thereby obtain ferric oxide particles or powder.Traditional spray drying tower is carrying out the iron oxide suspension of hot blast to spray pattern when carrying out drying, the hot blast skewness, and vaporific iron oxide suspension and hot blast are short time of contact, influence drying quality.
Summary of the invention
The technical problem that the utility model will solve provides the good inorganic pigment spray dryer of a kind of drying effect.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of inorganic pigment spray dryer, comprise cylindrical shell, and its innovative point is: said cylindrical shell bottom is provided with broach hopper; The top of said cylindrical shell is provided with hot-air distributor; The broach hopper sidewall is provided with outlet and is positioned on the broach hopper central axis and spray direction atomizer up, and the side walls of said broach hopper is provided with waste gas outlet, and the broach hopper bottom is provided with the star discharge valve.
Further, said hot-air distributor comprises scroll casing type hot blast dish, and said hot blast dish lateral wall is established air inlet, and the bottom sets out the air port, and hot blast disk center is equipped with taper bearing free to rotate, and said taper bearing outer wall is distributed with oblique wind deflector.
The advantage of the utility model is: the iron oxide suspension is through atomizer atomizing and ejection up; Hot blast through hot-air distributor in the shape of a spiral shape evenly get in the cylindrical shell; Contact with the iron oxide suspension of atomizing, the drop of suspension contacts back moisture and evaporates rapidly with high-temperature hot-air, in the extremely short time, just become dry products; Form ferric oxide particles and converge to the broach hopper bottom, discharge by the star discharge valve.Hot blast contacts the back temperature significantly to be reduced with the iron oxide drop of atomizing, and humidity increases, and it is discharged from waste gas outlet as waste gas, and the ferric oxide particles of carrying secretly in the waste gas can use pulse dust collector to reclaim.The emission direction of iron oxide drop can prolong hot blast and be in contact with it the time up, improves drying effect.
Description of drawings
Fig. 1 is the utility model inorganic pigment spray dryer structural representation.
Fig. 2 is partial enlarged drawing A among Fig. 1.
The specific embodiment
Like Fig. 1, shown in 2, comprise cylindrical shell 1, broach hopper 2, hot-air distributor 3, atomizer 4, waste gas outlet 5, star discharge valve 6.
The bottom of above-mentioned cylindrical shell 1 is provided with broach hopper 2; The top of cylindrical shell 1 is provided with hot-air distributor 3; This hot-air distributor 3 comprises scroll casing type hot blast dish 31, establishes air inlet at hot blast dish 31 lateral walls, and the bottom sets out the air port; 31 feel at ease taper bearing 32 free to rotate are housed in the hot blast dish, and taper bearing 32 outer walls are distributed with oblique wind deflector 33.
Broach hopper 2 sidewalls are provided with outlet and are positioned on broach hopper 2 central axis and spray direction atomizer 4 up, and the side walls of broach hopper 2 is provided with waste gas outlet 5, and broach hopper 2 bottoms are provided with star discharge valve 6.
Operation principle: the iron oxide suspension is atomized into droplet and ejection up through atomizer 4; Hot blast through hot-air distributor 3 in the shape of a spiral shape evenly get in the cylindrical shell 1; Contact with the iron oxide suspension of atomizing, the drop of suspension contacts back moisture and evaporates rapidly with high-temperature hot-air, in the extremely short time, just become dry products; Form ferric oxide particles and converge to broach hopper 2 bottoms, discharge by star discharge valve 6.Hot blast contacts the back temperature significantly to be reduced with the iron oxide drop of atomizing, and humidity increases, and discharges from waste gas outlet 5.
