Abstract

The invention discloses acid leaching equipment for high-silica glass fiber. According to the acid leaching equipment, the technical problems that high-silica glass fiber products produced by virtue of acid leaching in a traditional semi-automatic or manual process in the prior art cannot meet requirements, and the acid leaching production process of glass fiber cottons such as alkali glass fiber cottons cannot be smoothly and efficiently finished by virtue of existing equipment are solved. According to the adopted technical scheme, the acid leaching equipment comprises an acid reaction bucket, a heater, a stirrer and a filter bucket. According to the acid leaching equipment, a suspension liquid mixture, added in the acid reaction bucket, of acid and glass fiber cottons or chopped fibers is heated to a high temperature not higher than 100 DEG C and is continuously stirred to enable glass fibers to be in adequate contact with acid liquid to generate chemical reaction, the acid liquid automatically flows from a high liquid level into the filter bucket to be filtered, and then the acid liquid and the glass fibers are separated, thereby finishing the acid leaching production process of the high-silica glass fibers.

Description

technical field [0001] The invention relates to equipment for acid leaching treatment, in particular to equipment for acid leaching treatment of high silica glass fiber, belonging to the field of chemical equipment. Background technique [0002] The acid leaching production process is the most critical and core process in the production of high silica glass fiber wool. With the continuous improvement of users' requirements for product quality and stability, the traditional semi-automatic or manual process of acid leaching to produce high-silica glass fiber cotton products can no longer meet the requirements. In addition, with the advancement and development of production equipment science and technology, people have continuously improved the requirements for the production and working environment, thereby reducing the labor intensity of workers, reducing the time for workers to be exposed to acid liquid and acid gas, and improving work safety. The acid leaching process equi...
