Abstract

The invention relates to a device used for purifying zirconia fibers. The device comprises a hollow box (1), a temperature control device (2), a PLC, a probe, a thermometer and an anemograph, wherein the temperature control device (2), the PLC, the probe, the thermometer and the anemograph are arranged on the box (1). The temperature control device (2), the probe, the thermometer and the anemograph are connected with the PLC through signals. A plurality of draught fans (3) are fixedly connected to the top of the box (1). A plurality of heating tubes (4) are fixedly connected to the box (1). The draught fans (3) are connected with the temperature control device (2) through signals. By means of the structure, air convection can be avoided in the box, so that the temperature control device can accurately control the temperature to achieve gradient heating, different impurities are volatized at different temperatures, the volatized impurities can be timely discharged through the draught fans, the purity of the zirconia fibers can be guaranteed accordingly, and the product quality is improved.

Description

technical field [0001] The invention relates to a device for purifying zirconia fibers. Background technique [0002] After the zirconia fiber is formed, it is necessary to use heating to discharge the internal impurities in order to improve its purity. Due to the different internal impurities, a variety of temperature ranges are required to achieve the purpose of volatile impurities. The traditional process is completed by heating in a tunnel furnace, and the air convection is easy to form in the tunnel furnace, which makes it difficult to control the temperature accurately and stably, which causes some impurities to be unable to volatilize, reducing the purity of the zirconia fiber, and because of the high content of impurities , leading to a reduction in the heat insulation effect of zirconia products and a short service life. Although fans can be used to control the temperature, it is impossible to accurately control the temperature due to the inability to measure the te...
