Abstract
The utility model discloses a spraying dryer, including the drying tower, the drying tower top is equipped with feeding tube entrance and annular air intake, and the side is equipped with the air outlet, and the bottom is equipped with discharge gate, its characterized in that: still be equipped with gas distributor base on drying tower upper portion, gas distributor base is the annular and is equipped with a plurality of annular wind blades on, the wind blade is to the slope of the tower wall direction of drying tower, and during the material pipe got into the drying tower from feeding tube entrance, the atomizer was equipped with in material socle portion, and the atomizer is located the gas distributor base below. The utility model discloses in, annular air intake makes the hot -blast even drying tower that enters into, prevents that it inhales the material to produce the negative pressure in the gas distributor base top, and gas distributor base's annular wind blade is with the wind tower wall direction that leads for wind is rotatory downwards at the tower inside spin, reduces the material and glues the wall, and can take away the material that glues the wall on a small quantity, prevents that the material is for a long time attached to on the wall and lead to burning the paste.
Description
Technical field
The utility model relates to a kind of spray dryer, belongs to drying equipment technical field.
Background technology
Spray dryer is the one of continous way atmospheric dryer, adopt atomizer that material liquid is separated into droplet, and obtain product with the dry droplet of hot gas, main working process is: extraneous fresh air is by air cleaner, air blast, enter air heater, make air themperature bring up to about 160 DEG C, send drying tower to.Before entering drying tower, hot-air first by air uniform plate, makes hot-air be uniformly distributed, prevents vortex, avoid coke powder to occur, to ensure drying effect.Need the material liquid of dry process, atomizer is delivered to by compression pump, feed liquid is with vaporific ejection and mix with hot-air, material Micro-picking heat, moment moisture evaporation, forms powder falls downward, through one section of constant rate of drying, further transpiring moisture, coarse granule falls into the conical lower portion of drying tower and discharges.Dried material fine silt is separated through cyclone separator with the mixture of Low Temperature Wet air, and off-air is discharged by exhaust blower, and dry fine powder product falls is discharged continuously by discharger.
Operationally, moist material is thrown to after on drying tower wall spray dryer, often stick on top, and the material of sticky wall, likely can be burnt or rotten owing to resting on inwall for a long time, affects product quality; And the material after sticky wall often can lump and falls into discharging opening at the bottom of tower, product is made sometimes not reach moisture content and the fineness of regulation.
Utility model content
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of and reduce the spray dryer that material glues wall.
The technical solution adopted in the utility model is: a kind of spray dryer, comprise drying tower, described drying tower top is provided with the material mouth of pipe and circular air inlet mouth, side is provided with air outlet, bottom is provided with discharging opening, it is characterized in that: be also provided with gas distribution grid on drying tower top, described gas distribution grid is annular, be provided with multiple annular wind blade, described wind blade tilts to the Ta Bi direction of drying tower, material pipe enters drying tower from the material mouth of pipe, and bottom material pipe, atomizer is housed, atomizer is positioned at below gas distribution grid.
In the utility model, circular air inlet mouth makes hot blast enter into drying tower uniformly, prevent from above gas distribution grid, produce negative pressure material is sucked, wind leads Ta Bi direction by the annular wind blade of gas distribution grid, wind is rotated down at tower inside spin, reduce material and glue wall, and the material of sticky wall on a small quantity can be taken away, prevent from material to be attached to for a long time wall causes burnt.
Accompanying drawing explanation
Fig. 1 is the structural representation of spray dryer of the present utility model.
Fig. 2 is the profile of spray dryer of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further described.
Detailed description of the invention
Embodiment 1
As shown in Figure 1-2, this spray dryer, comprise drying tower 1, described drying tower top is provided with the material mouth of pipe 2 and circular air inlet mouth 3, side is provided with air outlet 4, bottom is provided with discharging opening 5, it is characterized in that: be also provided with gas distribution grid 6 on drying tower top, described gas distribution grid 6 is annular, be provided with multiple annular wind blade 7, wind blade 7 tilts to the Ta Bi direction of drying tower 1, and material pipe 8 enters drying tower 1 from the material mouth of pipe 2, bottom material pipe, atomizer 9 is housed, atomizer 9 is positioned at below gas distribution grid 6.
During work, material sprays from atomizer, the air of heating enters drying tower from circular air inlet mouth, evenly by gas distribution grid, with vaporific mixing of materials, material microparticle aqueous evaporates, bulky grain enters bottom drying tower, discharged by discharging opening, granule mixes with air discharges from air outlet, enters next process.
Claims (1)
