The utility model discloses be equipped with the double wall on the drying tower lateral wall, the cold air flows in the space between lateral wall and double wall, reduces tower wall temperature degree, reduces the material and glues the wall to can prevent that the material that glues the wall on a small quantity from burning the paste, when needs, the openable aviation baffle lets the cold air along wind -guiding mouth entering drying tower inner space, blows off adnexed material on the double wall the further material that glues the wall that reduces.
Description
Technical field
The utility model relates to a kind of antiseized wall 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 antiseized wall spray dryer that material glues wall.
The technical solution adopted in the utility model is: a kind of antiseized wall spray dryer, comprises drying tower, feed system, hot-air system, quenching system, cyclone separator, pulse bag filter, air-introduced machine;
Described drying tower comprises the hot air inlet, the charging aperture that are arranged at top, be arranged at the discharging opening of bottom, be arranged at the air outlet of side, described hot-air system is connected with hot air inlet, described feed system is by charging aperture convey materials, and described air outlet is connected with cyclone separator, pulse bag filter, air-introduced machine successively by pipeline;
Described drying tower inside sidewalls is provided with annular double wall, double wall is provided with several air guide holes guided by wind deflector, described wind deflector is opened and closed by Electric Machine Control, the angle of certain angle is formed when wind deflector is opened and between double wall, air guide hole is covered when wind deflector is closed, circulate in the space stoping drying tower sidewall and double wall to be formed and drying tower inner space, described drying tower sidewall is also provided with cold air inlet be connected with quenching system, cold wind enters the space between drying tower sidewall and double wall, enters drying tower inside when wind deflector is opened by air guide hole.
Preferably, described air guide hole is the strip slot evenly arranged along drying tower axis, and wind deflector is the arc strip board evenly arranged along drying tower axis.
Preferably, described quenching system comprises the air filter and air blast that connect successively, and air blast is connected with cold air inlet.
Preferably, the angle of 10-15 ° is formed when described wind deflector is opened and between double wall.
The utility model is provided with double wall on drying tower sidewall, cold air flows in space between sidewall and double wall, reduces tower wall temperature, reduces material and glues wall, and the material gluing wall on a small quantity can be prevented burnt, when needed, can wind deflector be opened, allow cold air enter drying tower inner space along air guide hole, because the angle of wind deflector and double wall is less, cold air can move in a circle along double wall, is blown off by the material that double wall adheres to, and reduces the material of sticky wall further.

Fig. 1 is the structural representation of spray dryer of the present utility model.
Fig. 2 is the A-A profile of antiseized wall spray dryer of the present utility model, and wherein wind deflector is open mode.
Fig. 3 is the A-A profile of antiseized wall spray dryer of the present utility model, and wherein wind deflector is closed condition.
Below in conjunction with drawings and Examples, the utility model is further described.
Detailed description of the invention
Embodiment 1
As Figure 1-3, this antiseized wall spray dryer, comprises drying tower 1, feed system, hot-air system, quenching system, cyclone separator 2, pulse bag filter 3, air-introduced machine 4;
Described drying tower 1 comprises the hot air inlet 11, the charging aperture 12 that are arranged at top, be arranged at the discharging opening 13 of bottom, be arranged at the air outlet 14 of side, described hot-air system is connected with hot air inlet 11, described feed system is by charging aperture 12 convey materials, and described air outlet 14 is connected with cyclone separator 2, pulse bag filter 3, air-introduced machine 4 successively by pipeline;
Described drying tower inside sidewalls is provided with annular double wall 15, double wall is provided with several air guide holes guided by wind deflector 16, described wind deflector 16 is controlled to open and close by motor 17, the angle of 10-15 ° is formed when wind deflector 16 is opened and between double wall, air guide hole is covered when wind deflector 16 is closed, circulate in the space stoping drying tower sidewall and double wall to be formed and drying tower inner space, described drying tower sidewall is also provided with cold air inlet 18 be connected with quenching system, cold wind enters the space between drying tower sidewall and double wall, drying tower inside is entered by air guide hole when wind deflector 16 is opened, described air guide hole is the strip slot evenly arranged along drying tower axis, wind deflector 16 is the arc strip board evenly arranged along drying tower axis,
Described quenching system comprises the air filter 5 and air blast 6 that connect successively, and air blast is connected with cold air inlet.
During work, material sprays from feed system, and the air of heating enters drying tower from hot air inlet, with vaporific mixing of materials, material microparticle aqueous evaporates, and bulky grain enters bottom drying tower, discharged by discharging opening, granule mixes with air discharges from air outlet, enters next process.Cold wind enters the space between drying tower sidewall and double wall from cold air inlet, double wall is cooled, reducing material is bonded on double wall, when sticky wall material is more, open wind deflector, cold wind enters in drying tower from air guide hole, because wind deflector angle is less, and hot-blast pressure is greater than cold wind pressure, therefore cold wind carries out circular motion along double wall, is taken away by the material that double wall adheres to.
