[0014] In summary, the technical effects and advantages of the utility model are:

[0015] 1. The utility model has a reasonable structure. The carbon nano-micro silica powder obtained by processing phytolith silica ore and caustic soda or soda ash are placed in a supply box in proportion, and then a Na2SiO3 solution is placed in the supply water tank. The Na2SiO3 solution in the supply water tank is discharged into the nozzle seat through a pipe by a water pump, and the Na2SiO3 solution is sprayed on the surface of the carbon nano-micro silica powder and the caustic soda or soda ash through an atomizing nozzle. The extrusion plate is moved downward by a supply hydraulic device, and the carbon nano-micro silica powder sprayed with the Na2SiO3 solution and the caustic soda or soda ash are squeezed through the extrusion plate to form a block raw material. The amount of Na2SiO3 solution is based on wetting and easy molding, which solves the problem of easy processing of carbon nano-micro silica powder and caustic soda or soda ash. The problems of dust in the air, increased energy consumption due to the need for aerobic or oxygen-free calcination after the treatment of phytolith silica ore, and high energy consumption caused by the high melting temperature during the in-situ reaction of Na2SiO3 in traditional carbon-containing nano-micro silica powder are solved by using liquid sodium silicate as a binder to prevent silicon powder dust from entering the air, and the raw materials are ultrafinely mixed and pressed into blocks before entering the smelting furnace to achieve green and clean production. The carbon content in the carbon-containing nano-micro silica powder is 3%, and the carbon burns and escapes at high temperatures. There is no need for aerobic or oxygen-free calcination after the treatment of phytolith silica ore, which can save some energy. The briquetting allows the Na2SiO3 in the carbon-containing nano-micro silica powder to react in situ, and the close distance allows the micro-area reaction to proceed smoothly, reducing the melting temperature, thereby achieving the effect of saving some energy.

[0016] 2. In the present invention, the supply motor rotates the supply screw to make the supply baffle discharge the block raw material from the reactor body into the high temperature box, and the supply motor rotates the supply screw to make the supply baffle close the docking hole on the upper surface of the reactor body. The temperature inside the high temperature box is increased to calcine the block raw material, and then the placement motor rotates the placement screw to make the placement baffle move parallel to drop the block raw material into the placement box, and then the placement motor rotates the placement screw to make the placement baffle close the upper surface of the placement box, and then it is left to stand and vented through the vent valve. The raw materials fall into the cold extraction box, and the docking motor rotates the docking screw to make the docking baffle move parallel to the raw materials after standing. After the raw materials fall into the cold extraction box, the docking motor rotates the docking screw to make the docking baffle close the lower surface of the placement box, and the raw materials are quenched to obtain bulk sodium silicate. The bulk sodium silicate is discharged into the crushing box through the discharge valve on the lower surface of the reactor body, and the crusher lever is rotated by the crushing motor to crush the bulk sodium silicate. The crushed bulk sodium silicate is then filtered through the filter plate, and the filtered sodium silicate powder falls into the collection box. BRIEF DESCRIPTION OF THE DRAWINGS
