During production, the raw materials quartz sand and soda ash are usually mixed in a raw material processing device, then placed in a reverberatory furnace and heated to 1400°C to react and produce molten silicic acid. For example, a high-efficiency raw material processing equipment for sodium silicate production (publication number CN217140318U) disclosed on the China Patent Network uses stirring blades in the stirring and dehumidification structure to drive the stirring of the raw materials, and uses a heating block to heat and dehumidify the moisture in the stirred raw materials, thereby improving machine efficiency and improving the quality of the processed sodium silicate.

[0003] However, the sodium silicate raw material processing devices used in the above-mentioned patents and the existing market still have some shortcomings: the existing method of using a horizontal stirring component to drive the horizontal stirring and mixing of the sodium silicate raw material, and using a heating component for heating and dehumidification, can only perform horizontal stirring, mixing, heating and dehumidification, which not only has poor stirring and mixing uniformity of the sodium silicate raw material, but also cannot fully guarantee the heating and dehumidification performance of the raw material. To this end, those skilled in the art provide a raw material processing device for sodium silicate production to solve the problems raised in the above-mentioned background technology.

[0023] A circulating material lifting mechanism is installed inside the tank body of the material tank 1 along the axial direction of the brake shaft 9. The circulating material lifting mechanism includes a lifting cylinder 15 installed inside the material tank 1 along the axial direction of the brake shaft 9 and a spiral screw dragon 21 installed on the brake shaft 9, and the spiral screw dragon 21 is built into the inside of the barrel of the lifting cylinder 15. The bottom end of the barrel of the lifting cylinder 15 is provided with multiple groups of feed ports 20 along its circumferential direction, and the top end of the barrel of the lifting cylinder 15 is provided with multiple groups of discharge ports 19 along its circumferential direction. A second heating coil 18 is provided below the opening of the discharge port 19 on the outer side of the barrel of the lifting cylinder 15, and the outer side of the barrel of the lifting cylinder 15 is provided with a plurality of feed ports 20 along its circumferential direction. A first heating coil 17 is provided above the opening of the feed port 20. Both the first heating coil 17 and the second heating coil 18 are spiral coil structures. By utilizing the linkage heating combination of the first heating coil 17 and the second heating coil 18, when the sodium silicate raw material is circulated and pumped up under the combination of the lifting barrel 15 and the spiral auger 21, the raw material batching tank 1 dynamically circulates at the bottom, and the first heating coil 17 is utilized to dynamically heat and dehumidify the raw material. When the sodium silicate raw material is circulated and pumped back along the lifting barrel 15, the second heating coil 18 is utilized to dynamically heat and dehumidify the raw material to remove moisture in the raw material.

[0024] The outer side of the tube of the lifting barrel 15 is provided with an annular cover of the second heating coil 18 and a material blocking cover 16 of the discharge port 19. By setting the material blocking cover 16, when the sodium silicate raw material is circulated and extracted from the discharge port 19, the annular cover of the material blocking cover 16 is utilized to allow the raw material to be heated by the second heating coil 18 before it can fall back into the batching tank 1, thereby ensuring that the raw material is heated comprehensively and fully.

[0025] A stirring and mixing mechanism is installed inside the tank body of the ingredient tank 1 horizontally in the shaft direction of the brake shaft 9. The stirring and mixing mechanism includes a transmission shaft 13 symmetrically installed on the ingredient tank 1 horizontally in the shaft direction of the brake shaft 9 and a transmission gear 10 installed on the shaft of the brake shaft 9. A plurality of stirring impellers 14 are arranged on the outer side of the shaft of the transmission shaft 13, and a synchronous gear 12 is installed on the top of the shaft of the transmission shaft 13. The synchronous gear 12 and the transmission gear 10 are connected by a transfer gear 11. When the brake shaft 9 rotates, the transmission gear 10 is driven to rotate. The meshing transmission of the transfer gear 11 drives the synchronous gear 12 to rotate, and then drives the transmission shaft 13 to rotate, pushing the stirring impeller 14 on its shaft to rotate, and horizontally stirring the sodium silicate raw material in the ingredient tank 1 to improve the uniformity of the processing and mixing of the sodium silicate raw material.

[0026] The upper end of the tank body of the batching tank 1 is symmetrically provided with a feeding pipe mouth 3, and the bottom of the batching tank 1 is installed with a discharge valve 2 which is connected to the lifting cylinder 15. The sodium silicate raw material is added into the batching tank 1 through the feeding pipe mouth 3 for heating, dehumidification, stirring and mixing. Then, the transmission combination of the lifting cylinder 15 and the spiral auger 21 is utilized. When the spiral auger 21 rotates in the opposite direction, the mixed and dehumidified raw materials are discharged through the discharge valve 2 into the reverberatory furnace for heating and melting.

[0027] The working principle of the utility model is as follows: when the sodium silicate raw material is melt-processed, the quartz sand and soda ash raw materials are fed into the batching tank 1 through the feeding nozzle 3, and then the brake motor 5 is controlled to work, driving the combined transmission of the differential pulley A6, the transmission belt 7, and the differential pulley B8, and then driving the brake shaft 9 to rotate as a power source to drive the corresponding components to operate;

[0028] As the brake shaft 9 rotates, it drives the spiral auger 21 to rotate, and the sodium silicate raw material flowing into the lifting barrel 15 is circulated and transported upward through the feed port 20, and circulated back through the discharge port 19. Then, by utilizing the circulatory upward pumping of the sodium silicate raw material, on the one hand, the raw material is kept in dynamic flow so as to fully contact with the first heating coil 17 and the second heating coil 18 for heating and dehumidification, and on the other hand, the upper and lower layers of raw materials are fully dynamically stirred and mixed to improve the uniformity of raw material mixing;

[0029] When the brake shaft 9 rotates, it drives the transmission gear 10 to rotate, and the meshing transmission of the transfer gear 11 drives the synchronous gear 12 to rotate, which in turn drives the transmission shaft 13 to rotate, and drives the stirring impeller 14 on its shaft to rotate, thereby horizontally stirring the sodium silicate raw material in the batching tank 1 to improve the uniformity of the processing and mixing of the sodium silicate raw material;

[0030] After the sodium silicate raw material is heated, dehumidified, stirred and mixed, the spiral auger 21 is controlled to reverse and push the raw material downward, so that the raw material is discharged through the discharge valve 2 into the reverberatory furnace for heating and melting.

[0031] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
