Vacuum forming refractory fiberboard production line and its application method

Abstract

The invention discloses a vacuum-forming fireproof fiberboard production line, comprising a powder and cotton system, a pulping system, a molding and cutting system, a drying system and an automatic packaging system; wherein the powder and cotton system is a powder and cotton machine comprising a frame, a motor, a grinding wheel and a shaking sieve, a conveyor belt is arranged on the frame of the pink cotton rack, the motor is drivingly connected with the grinding wheel, a dust collecting cover is arranged above the shaking sieve, a conduit is connected to the dust collecting cover, the end of the conduit is connected to a fan, one end of the conveyor belt is arranged below the grinding wheel, the other end is arranged on the top of the shaking sieve, and the powder and cotton motor and the shaking sieve motor are fixedly mounted on the frame. The shaking sieve motor drives the shaking sieve to shake, the fan and the dust collecting cover remove the powder made by the shaking sieve, and the shaking sieve collects the waste made by the grinding wheel smashing the ceramic fiber. The vacuum forming fireproof fiberboard production line has the advantages of being simple in structure, easy to use, low labor intensity, less labor, and both sides of the fiberboard are smooth without cracks.

Description

Technical field: [0001] The invention relates to the technical field of production equipment for special mineral refractory fiber products, in particular to a vacuum forming refractory fiberboard production line and its use method. Background technique: [0002] The current production process of refractory fiberboard is: put the mold into the forming pool, use the negative pressure formed by the mold cavity to make the fiber slurry adsorb on the mold, and obtain a fiber wet blank with the same shape and size according to the shape and size of the model . The thickness of the product is controlled by the adsorption time of the mold in the forming pool. After reaching the wet-laid part size, the fiber-absorbed mold is lifted from the forming tank. Then turn on the vacuum pump again to carry out vacuum dehydration on the fiber wet billet adsorbed on the mold, and finally use the air blowing method to demould the formed wet billet. The strength of the wet billet is poor, so i...

Problems solved by technology

[0003] In summary, the vacuum-formed refractory fiberboard produced by the prior art has uneven surface due to the limitation of the production process; The geometric deformation of the product is easy to occur during the molding; due to the inaccurate geometric size of the product, the wall after construction is uneven, the construction gap is large, the thermal conductivity is high, and the application of unshaped materials such as construction adhesives and paints is increased, thus limiting The large-scale promotion of products makes the function of refractory fiberboard not fully reflected

The drying of the wet refractory fiberboard is to use pallets and racks to stack layers, and the drying room uses heat-conducting oil to heat the air. The hot air drying method and the hot air stove method; The heat absorption is large, which causes the heating time to be too long. The refractory fiberboard stays for too long in a low-temperature and high-humidity environment, which accelerates the reproduction and growth of microorganisms in the refractory fiberboard. Fiber arrangement, reducing the quality of refractory fiberboard

In the later stage of drying the refractory fiberboard, because the refractory fiberboard is a heat insulation product, the heat is not easily transmitted to the inside of the refractory fiberboard, resulting in low drying efficiency and long drying time. If the drying temperature is increased, the color of the dried board will turn yellow or even Blackening also affects the quality of refractory fiberboard

Due to the current production process, according to different orders, different molds are used for vacuum forming, trays are used for drying, and the dried products are polished and packaged; therefore, there are many links, many labors, and low output.
