Abstract
The present invention discloses the drying process for rubber chemicals. The present invention solves the problems of low material drying rate and insufficient material drying in the present drying process for the rubber chemicals. The present invention has the advantages of favorable drying effect, high thermal efficiency, small product granularity, little investment, etc. The present invention has the technological processes of feeding, drying by a flash evaporation drier and an air flow dryer, and end gas emptying after dust removal and gathering. The utility model is characterized in that moist material is conveyed to the flash evaporation drier through a charger; the flash evaporation drier carries out thrashing and drying to the material; then the semidry material are dried secondarily in air flow; the dried material are conveyed to a bag dust collector for dust removal and gathering and end gas emptying.
Description
Technical field
The present invention relates to a kind of drying process of rubber chemicals.
Background technology
Existing rubber chemicals drying process is a twin-stage airflow drying process, and the shortcoming of its existence is a dry gas stream speed height, and residence time of material is short, and drying effect is poor, and the product water content fluctuates easily; In dry run, rubber chemicals toughness, wet stock be sticking wall on gas flow tube easily, cleaning difficulty behind the sticking wall.Simultaneously, twin-stage gas flow process route complexity, dry air quantity and pressure head are big, the power consumption height, capacity usage ratio is low, and the thermal efficiency is low, the operating cost height; The dust pelletizing system complexity, occupation area of equipment is big, and investment is high, and discharging point is many, operating difficulties, labor strength is big.
Summary of the invention
It is low in order to solve in the present rubber chemicals drying process dry materials rate that purpose of the present invention is exactly, the inadequate problem of dry materials, provide the combination of a kind of employing flash dryer and its fluidized drying machine to carry out drying twice, it is good that this drying process has a drying effect, thermal efficiency height, product granularity is little, advantages such as small investment.
For achieving the above object, the present invention has adopted following technical scheme: a kind of drying process of rubber chemicals, its technical process is, feeding, flash dryer add the oven dry of pneumatic conveying drying machine, back tail gas emptying is collected in dedusting, it is characterized in that: wet stock is sent into flash dryer through charger, flash dryer to material break up, drying, half-dried then material carries out secondary drying in air-flow, dry good material is sent into the sack cleaner dedusting and is collected the tail gas emptying.
Described flash dryer is communicated with the plant air of heating, after plant air process filter and the heat exchanger heating, sends into flash dryer through pipeline.
Described sack cleaner is connected with blower fan by pipeline, and the plant air behind the bag-type dust is by the blower fan emptying.
The present invention combines flash dryer and dry air-flow process on the basis of existing dry air-flow process, forms drying twice, thereby has fully improved the drying efficiency of material; Because the disintegrating mechanism of rotation is at a high speed arranged in the flash dryer, not only the material of bulk can be broken up, pulverized simultaneously, can also add the disturbance of air blast and wet stock, improve dry tenacity, reduce equipment volume, thereby save equipment investment.This drying process can prolong the material drying residencing time, the drying efficiency height; Material particles after breaing up is little, is more than 100 orders, can realize the classification of product by the method for controlled wind speed, not sticking wall, and the equipment that do not influence moves continuously, and whole technology investment is little, and floor space is little.
Description of drawings
Fig. 1 is a process chart of the present invention.
Wherein, 1. filter, 2. heat exchanger, 3. charger, 4. flash dryer, 5. pneumatic drier, 6. sack cleaner, 7. blower fan.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
Among Fig. 1, wet stock enters flash dryer 4 through charger 3, and the plant air that is made of air, condensed water and saturated vapor is also sent into expansion drying 4 machines after through filter 1 and heat exchanger 2.Flash dryer 4 is broken up back and high-temperature technology air combination drying with material, material is sent into pneumatic drier 5 to carry out the second time dry then, dry good material is sent into sack cleaner 6 and is carried out the dedusting collection, sack cleaner 6 is connected with blower fan 7, plant air behind the bag-type dust enters blower fan 7 emptyings, and finished product is sent and got final product.
