Special drying device for organic silicon-resin production

Abstract

The invention discloses a special drying device for organic silicon-resin production, which comprises a closed shell, a delivery pump and a driving pump, wherein the delivery pump is installed on a high-position storing slot at the upper part of the shell by being communicated with a feeding pipeline, the high-position storing tank is communicated with a material homogenizer at the upper part in the shell, a drying roller which is installed on the shell through a shaft is arranged below the material homogenizer, a scraper clings to the outer wall of the drying roller, a bunker is arranged below the drying roller, the drying roller is connected with and driven by the driving pump, a heater is communicated with an inner cavity of the drying roller through a heat-conducting oil-conveying pipe, a solvent-recovering pipeline, one end of which extends into the shell is communicated with a cooler, the cooler is communicated with a solvent-recovering and storing tank, and the solvent-recovering and storing tank is connected with a vacuum pipe through a vacuum pipeline. The special drying device for the organic silicon-resin production has the characteristics that roller-drying equipment is adopted, the product quality and the production efficiency are improved, the solvent-recovering efficiency is high, environmental pollution is avoided, and the special drying device is safe and reliable.

Description

[0001] technical field [0002] The invention belongs to the technical field of chemical production equipment, and in particular relates to a special drying equipment for producing organic silicon resin by solvent method. Background technique [0003] In the process of producing silicone resin, the traditional drying method, one is to remove the solvent in the original production equipment to obtain the product, and the other is to enter the spray drying system through the pipeline, and the product is obtained after spray drying; the characteristic of the first method is that when the product When the content of the solvent is not required to be high, it is convenient to obtain qualified products. When the content of the solvent is not higher than 3%, it is difficult to obtain qualified products by this method, and it is easy to obtain a qualified product during the process of removing the solvent and drying. Due to the high temperature, the material turns yellow and deterio...

Problems solved by technology

[0003] In the process of producing silicone resin, the traditional drying method, one is to remove the solvent in the original production equipment to obtain the product, and the other is to enter the spray drying system through the pipeline, and the product is obtained after spray drying; the characteristic of the first method is that when the product When the content of the solvent is not required to be high, it is convenient to obtain qualified products. When the content of the solvent is not higher than 3%, it is difficult to obtain qualified products by this method, and it is easy to obtain a qualified product during the process of removing the solvent and drying. Due to the high temperature, the material turns yellow and deteriorates; although this method is simple to recover the solvent and does not pollute the environment during the process of recovering the solvent, the drying efficiency of this method is low, which greatly affects the production efficiency. The second method can be a good solution In the first method, the finished product requires low solvent content, and the production efficiency has also been greatly improved; but the problem in the second method is that the solvent is difficult to recycle, which causes great harm to the environment
