process S5: after the operation state of the motor 27 and the air pump 22 is stabilized, the second valve 29 is opened to inject the rock slurry into the centrifuge tube 16 through the raw material inlet tube 28, and the rock slurry is centrifuged into fiber filaments by the interaction of the centrifugal force generated by the rotation of the second hollow rolls 31 and the hot air ejected through the air vents 32.

The working principle and the using process of the invention are as follows: after the device is installed, mixing granular cotton 1, anion mineral powder 2, shell powder 3, waste molecular sieve catalyst 4, bentonite 5, plant fiber 6, starch 7, flocculant 8, dispersant 9, sterilization mildew preventive 10, active carbon 11, nano titanium dioxide 12, spinel ferrite 13 and water 14, injecting the mixture into melt supply equipment as raw materials to be melted into rock pulp liquid, firstly connecting one end of an air guide pipe 23 far away from an air pump 22 into the melt supply equipment, simultaneously connecting one end of a raw material inlet pipe 28 far away from a centrifugal cylinder 16 into the melt supply equipment, then firstly opening a first valve 24, operating a second switch 34 to enable the air pump 22 to run, and in the working process of the air pump 22, leading high-temperature air into a first hollow roller 19 through a pipeline consisting of the air guide pipe 23 and a connecting pipe 21 by utilizing the attraction generated by the air pump 22 in the working process, then the high temperature air introduced by the first hollow roller 19 is distributed into a plurality of second hollow rollers 31 by the diversion body 30, and finally is ejected through the air vents 32 and acts on the centrifugal cylinder 16, then the first switch 33 is operated to make the motor 27 run, during the working process of the motor 27, the output shaft of the motor 27 can utilize the gear set between the first gear 25 and the second gear 26 to act the torsion on the first hollow roller 19, so that the first hollow roller 19 rotates in the first bearing 18, and the diversion body 30 drives the plurality of second hollow rollers 31 to carry out high-speed rotation centrifugal action in the separation cylinder, so that the working state of the motor 27 and the air pump 22 tends to be stable, then the second valve 29 is opened to inject the rock slurry into the centrifugal cylinder 16 through the raw material inlet pipe 28, under the mutual action of the centrifugal force generated by the rotation of the plurality of second hollow rollers 31 and the hot air ejected through the air vents 32, therefore, the rock pulp liquid can be centrifuged into fiber filaments, after the fiber filaments are processed into mineral wool limiting plates, air negative ions can be released indoors under the action of illumination and heat, so that a certain sterilization and disinfection effect can be achieved, the mineral wool plates can effectively adsorb and decompose free formaldehyde, benzene, ammonia, sulfide and other harmful substances in air, the peculiar smell of the air is obviously reduced, the air humidity can be adjusted, the indoor living environment is improved, meanwhile, the mineral wool plate has a good water 14 breathing function, the surface of the mineral wool plate manufactured in a low-pressure and high-humidity state is not prone to dewing, and the water 14 stored in the mineral wool plate can be slowly released under a dry condition, so that the breathing function of the mineral wool plate is a regulator of the humidity inside the mineral wool plate, the dewing and the generation of microorganisms are prevented, and the mineral wool plate is bacteriostatic and anticorrosive.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
