Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] figure 1 In the process, the wet material enters the flash dryer 4 through the feeder 3, and the process air composed of air, condensed water and saturated steam is also sent into the flash dryer 4 after passing through the filter 1 and the heat exchanger 2. The flash dryer 4 breaks up the material and mixes it with high-temperature process air for drying, then the material is sent to the airflow dryer 5 for the second drying, and the dried material is sent to the bag filter 6 for dust collection, and the bag filter 6 and The fan 7 is connected, the process air after bag dust removal enters the fan 7 to be emptied, and the finished product can be sent out.

Abstract

The invention discloses rubber assistant drying technique. It has the advantages of good drying effect, high heat efficiency, small product grain, and little investment. The technique includes the following steps: feeding; drying; collecting after dusting and emptying end gas. Its features are sending wet material to flash dryer by charger; breaking up and drying; doing secondary drying for damp-dry material; dusting and collecting by bag dust collector; emptying end gas.

Description

technical field [0001] The invention relates to a drying process for rubber additives. Background technique [0002] The existing drying process of rubber additives is a two-stage airflow drying process, which has the disadvantages of high drying air velocity, short material residence time, poor drying effect, and easy fluctuation of product moisture content; during the drying process, rubber additives have Viscous, wet materials are easy to stick to the wall of the air flow pipe, and it is difficult to clean up after sticking to the wall. At the same time, the two-stage air flow process route is complicated, the drying air volume and pressure head are large, the power consumption is high, the energy utilization rate is low, the thermal efficiency is low, and the operating cost is high; the dust removal system is complex, the equipment occupies a large area, high investment, and many discharge points. The operation is difficult and the labor intensity of the workers is high...
