Abstract
The invention relates to a drying technology of solution polymerized butadiene styrene rubber. The drying technology comprises the following steps of: (1) a primary rubber particle drying section: water-bearing rubber particles from a head of an expansion dryer enter a first section vibration fluid bed dryer to accomplish removal of flash evaporation moisture by suction, (2) a surface moisture extraction section of the rubber particles: the water-bearing rubber particles enter a second section vibration fluid bed for dryness and removal of surface moisture, and the temperature is controlled at 100 DEG C, (3) a subsurface moisture evaporation section of the rubber particles: the water-bearing rubber particles enter a third section vibration fluid bed for dryness and removal of subsurface moisture, and the temperature is controlled at 85 DEG C, (4) an internal moisture evaporation section of the rubber particles: the water-bearing rubber particles enter a fourth section vibration fluid bed for dryness and removal of internal moisture, and the temperature is controlled below 50 DEG C, (5) a rubber particle cooling section: the qualified rubber particles enter a fifth vibration fluid bed for cooling, and the temperature is room temperature, and (6) packaging: the rubber particles with the appropriate temperature are conveyed to a packaging bin via a rotary feeder valve and a roots blower system in a vacuum conveying manner, and packaged after re-cooled.
Description
Technical field
The present invention relates to solution polymerized butadiene styrene rubber Drying Treatment Technology field, particularly relate to a kind of solution polymerized butadiene styrene rubber drying process.
Background technology
Domestic solution polymerized butadiene styrene rubber post processing follow-up dry technology present situation: the continuous three sections of seasonings of (1) Vibratingfluidbeddrier: mostly adopt three Vibratingfluidbeddriers to carry out follow-up drying to remove the moisture in solution polymerized butadiene styrene rubber micelle at present--first paragraph removes flash distillation water; 2nd section removes micelle surface water; 3rd section removes micelle internal water and cools micelle.Because solution polymerized butadiene styrene rubber is not General Purpose Rubber, the moisture therefore removed in solution polymerized butadiene styrene rubber micelle is quite difficult; Or under the same conditions, the production capacity of device is lower.(2) Vibratingfluidbeddrier adds roller drier combined method; (3) fourdrinier wire seasoning.
The follow-up drying means of external solution polymerized butadiene styrene rubber has following several mode, they cut both ways: (1) fourdrinier wire seasoning: with the micelle of the crawler type fourdrinier wire drying box conveying moisture content 5-8% of long 30--45 rice, wide 2--4 rice, and in course of conveying, obtain drying and cooling.Its advantage is that the physical property of material can not be affected, and production capacity can adjust at any time; Its shortcoming is that plant equipment is heavy, and take up an area space greatly, energy ezpenditure is large, and construction cost is large, and maintenance and repair expense is many.(2) to add cylinder helical-blade dryer group legal for Vibratingfluidbeddrier: Vibratingfluidbeddrier is mainly used to extract the steam of a large amount of flash distillation; Cylinder is mainly used in moisture in dry solution polymerized butadiene styrene rubber pimpled rubber to qualified.The advantage of cylinder drying in running, can change condition of work at any time, and shortcoming is that the individual particles in cylindrical shell to stick on part not easy to clean, and the time has been grown and can turn yellow; Energy ezpenditure is larger simultaneously, invests also larger.(3) the continuous three sections of seasonings of Vibratingfluidbeddrier: about 10 meters of the every segment length of external vibrated fluidized bed, overall length 30 meters, width is 1.2--1.4 rice.Equipment is heavy, and investment is large, and maintenance cost is large, but production capacity is also comparatively large, but three sections regulate inconvenient.
Summary of the invention

(3) micelle subsurface moisture evaporator section: moisture micelle enters the 3rd section of vibra fluidized bed drying again and removes subsurface moisture, and temperature controls at 85 DEG C;
(4) micelle internal moisture evaporator section: moisture micelle enters the 4th section of vibra fluidized bed drying again and deviates from internal moisture, and temperature controls below 50 DEG C;
(5) micelle cooling section: qualified micelle enters the 5th section of vibrated fluidized bed and cools, and temperature is normal temperature;
(6) pack: the suitable micelle of temperature by rotatory feeder valve and roots blower system vacuum mode of movement send to packaging feed bin again in but pack afterwards.
Further, described 1st section is the hot air fluidized bed of upward type, and described 2nd section is blowing down hot air type fluid bed, and described 3rd section is blowing down hot air type fluid bed, and described 4th section is upward type warm air fluid bed, and described 5th section is upward type cool breeze fluid bed.
Further, the hot air fluidized bed of described upward type, blowing down hot air type fluid bed, upward type warm air fluid bed and upward type cool breeze fluid bed adopt frequency conversion type air-blower control technology.
Further, the hot air fluidized bed of described upward type, blowing down hot air type fluid bed, upward type warm air fluid bed and upward type cool breeze fluid bed adopt the anti-product bonding technology of Teflon.
Compared with prior art, the invention has the advantages that: the follow-up dry production capacity 6 tons/hour of post processing of the present invention; Solution polymerized butadiene styrene rubber finished product glue volatile matter content is less than 0.7% and is less than industry index 1.0% index; Discharged air meets national environmental standard, and steam energy consumption and power consumption reduce greatly, and equipment is advanced, operate, safeguard simple and convenient, can large-scale promotion.
