and the sintering device is arranged at the output end of the dicing device.
5. A continuous automatic batch preparation method of ceramic fiber fireproof plates, which is characterized by being implemented by adopting the continuous automatic batch preparation device of ceramic fiber fireproof plates according to claim 4, comprising the following steps:
s1, pulping, namely pouring ceramic fibers and nonmetallic boride into a feeding device by using water, uniformly mixing, and regulating the pH of the slurry by using concentrated ammonia water;
s2, suction filtration, namely spraying the slurry on a first conveyor belt through a nozzle of a discharging device, and dehydrating and suction-filtering wet blanks through a vacuum-pumping device;
s3, pressing the wet blank, and conveying the wet blank into a pressing device through a first conveying belt to press out a part of water;
s4, drying and dicing, namely placing the wet blank on a non-metal clamp, loading the wet blank into a drying device for drying, and unloading the wet blank onto a dicing device for dicing through the non-metal clamp;
s5, sintering, namely loading the cut plates onto a soaking pressurizing plate, and transferring the plates into a sintering device for sintering;
s6, machining and milling, namely unloading the sintered and cooled plate from the soaking and pressurizing plate to a milling device for milling.
6. The continuous and automatic batch production method of ceramic fiber fireproof plates according to claim 5, wherein in the step S1, the total amount of the ceramic fiber and the nonmetallic boride is 0.3-1wt% of the amount of water.
7. The continuous and automatic batch preparation method of ceramic fiber fireproof plates according to claim 6, wherein the non-metal boride is 0.5-20wt% of the ceramic fibers.
8. The continuous and automatic batch preparation method of ceramic fiber fireproof plates according to claim 6 or 7, wherein in the step S1, the ceramic fibers consist of 30-85% of quartz fibers, 4.9-55% of alumina fibers and 0.1-15% of zirconia fibers in percentage by mass.
9. The continuous and automatic batch production method of ceramic fiber fireproof plate according to claim 5, wherein the ceramic fiber can be selected from fibers with a length of 500 μm to 5mm and a diameter of 1 μm to 10 μm.
10. The continuous, automated batch manufacturing process for ceramic fiber fire protection plates of claim 5 wherein in step 1 the PH is adjusted to a value of 9 to 11.
