Description

Technical Field

[0001] The utility model relates to the field of sodium silicate production equipment, in particular to a sodium silicate static pressure kettle. Background Art

[0002] Sodium silicate is an inorganic substance. Its aqueous solution, commonly known as water glass, is a mineral binder. Its production process mainly involves using solid sodium silicate as the raw material, passing it through steam at a certain temperature and pressure in an autoclave, adding an appropriate amount of water, and through proper operation, it can be dissolved into the required liquid sodium silicate. The autoclave, as the main equipment for sodium silicate production, is an indispensable facility in the production of liquid sodium silicate. For example, as shown in the solid sodium silicate autoclave disclosed on the China Patent Network (Announcement No. CN220276863U), this type of device adds the raw materials to the autoclave body for mixing. The cleaning arc plate in the cleaning mechanism then scrapes the mixture adhering to the inner wall up and down to clean it. The unblocking drill in the unblocking mechanism unclogs the discharge port to ensure normal production.

[0003] However, the sodium silicate autoclaves used in the aforementioned patents and in the current market still have some shortcomings: the existing method of using independent components to scrape, clean, and prevent blockage of the mixed sodium silicate raw materials has poor integrated linkage, and the post-cleaning method easily leads to incomplete mixing of the sodium silicate raw materials, causing raw materials adhering to the inner wall to be discharged along with the finished raw materials, resulting in relatively low static pressure mixing quality. To this end, those skilled in the art have provided a sodium silicate autoclave to address the problems raised in the above background technology. Utility Model Content

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-4 The utility model provides a technical solution for a sodium silicate static pressure kettle: a sodium silicate static pressure kettle, comprising a kettle body 1, a plurality of groups of feeding valves 3 are arranged along the circumference of the upper end of the kettle body 1, and a steam valve 2 is installed on the upper end of the kettle body 1, and a discharge valve 5 is installed along the shaft direction of the brake shaft 6 at the conical bottom of the kettle body 1. The feeding valve 3 is used as a filling valve for various raw materials of sodium silicate (solid sodium silicate, water and other raw materials), and the sodium silicate raw materials are added into the kettle body 1, and then the steam valve 2 is used as a steam pressurizing valve. When the steam enters the interior of the kettle body 1, the heat energy of the steam will be transferred to the material in the kettle, causing its temperature to increase, and the heat is transferred to the material quickly and evenly, thereby achieving the effect of rapid heating. At the same time, the high temperature and high pressure of the steam can also effectively kill bacteria, thereby achieving the purpose of sterilization and disinfection.

[0024] A brake shaft 6 is installed in the middle of the chamber of the kettle body 1, and a brake motor 4 is provided on the top of the shaft of the brake shaft 6. The brake shaft 6 and the linkage shaft 9 are engaged and driven by a differential linkage mechanism. The differential linkage mechanism includes a first differential gear A11 installed on the upper end of the shaft of the brake shaft 6 and a second differential gear B14 installed on the upper ends of the shafts of the two sets of linkage shafts 9. The first differential gear A11 is symmetrically meshed with the first differential gear B12 on both sides, and each set of the second differential gear B14 is meshed with the second differential gear A13 on one side, and the first differential gear The wheel B12 and the second differential gear A13 are coaxially driven with each other. By controlling the brake motor 4 as the power source, the brake shaft 6 is driven to rotate, and then the first differential gear A11 is driven to rotate. The meshing transmission of the first differential gear A11 and the first differential gear B12 is used to drive the second differential gear A13 to rotate. Then, the meshing transmission of the second differential gear A13 and the second differential gear B14 is used to drive the linkage shaft 9 to operate synchronously. The differential synchronous operation of the brake shaft 6 and the linkage shaft 9 is used to drive the corresponding components to perform static pressure mixing on the sodium silicate raw material.

[0025] The outer side of the shaft of the brake shaft 6 is provided with a scraper 7 that fits the inner wall of the kettle body 1. The scraper 7 includes a positioning sleeve 71. Arm plates 72 are symmetrically provided on both sides of the positioning sleeve 71. A cleaning scraper 74 that fits the inner wall of the kettle body 1 is provided on one side of the plate frame of the arm plate 72, and a plurality of groups of material-dipping blades 75 are arranged on the other side of the plate frame of the arm plate 72. The bottom plate of the arm plate 72 is provided with a pusher inclined plate 73 that fits the cone bottom of the kettle body 1. When the brake shaft 6 rotates, it drives The scraper 7 rotates smoothly, and the cleaning scraper 74 in the scraper 7 scrapes and cleans the material adhering to the inner wall of the kettle body 1 by cyclic scraping, thereby avoiding material adhesion and affecting the mixing quality. The pushing inclined plate 73 in the scraper 7 is cyclically unloaded and pushed to stir and push the solid sodium silicate raw material at the bottom of the kettle body 1, so that the solid sodium silicate raw material is fully mixed with water. The turbulence driven by the paddle 75 in the scraper 7 can further improve the diversification of the stirring and mixing of the sodium silicate raw material.

[0026] The interior of the chamber of the kettle body 1 is symmetrically installed with linkage shafts 9 on both sides of the brake shaft 6, and a plurality of stirring paddles 10 are arranged at the bottom end of the shaft of the linkage shaft 9. The number of stirring paddles 10 is not less than two groups, and the stirring paddles 10 are propeller structures. When the linkage shaft 9 rotates, the stirring paddles 10 are driven to rotate rapidly. The stirring drive of the stirring paddles 10 is used to fully stir and mix the sodium silicate raw material, so that the static pressure mixing efficiency is more efficient and comprehensive.

[0027] The bottom end of the shaft of the brake shaft 6 is provided with a stirring screw 8 opposite to the discharge valve 5. By utilizing the combination of the stirring screw 8 and the brake shaft 6, on the one hand, the sodium silicate raw material at the bottom of the kettle body 1 can be spirally pushed to avoid the sodium silicate raw material from clogging the discharge pipe. On the other hand, after the sodium silicate is statically mixed, the material in the discharge valve 5 can be dynamically flowed to avoid blockage during unloading.

[0028] The working principle of the utility model is as follows: when using a static pressure autoclave to produce liquid sodium silicate, solid sodium silicate, water and other raw materials are added into the autoclave body 1 through the feeding valve 3, and then the steam from the steam valve 2 is used for pressurization, while heat is transferred to the sodium silicate raw materials in the autoclave body 1, and a high-pressure and high-temperature sterilization process is performed;

[0029] Furthermore, during the hydrostatic production of sodium silicate, the brake motor 4 is controlled as a power source to drive the brake shaft 6 to rotate, which in turn drives the combined transmission of the first differential gear A11 and the first differential gear B12, and synchronously drives the combined transmission of the second differential gear A13 and the second differential gear B14, thereby promoting the synchronous operation of the linkage shaft 9. The differential synchronous operation of the brake shaft 6 and the linkage shaft 9 drives the corresponding components to hydrostatically mix the sodium silicate raw material.

[0030] Then, while the brake shaft 6 rotates, it drives the scraper 7 to rotate smoothly, and the cleaning scraper 74 in the scraper 7 scrapes and cleans the material adhering to the inner wall of the kettle body 1 to prevent material adhesion. Synchronously, the pushing inclined plate 73 in the scraper 7 is used to push and stir the solid sodium silicate raw material at the bottom of the kettle body 1, so that the solid sodium silicate raw material is fully mixed with water. The turbulence driven by the paddle 75 in the scraper 7 can improve the mixing and diversification of the sodium silicate raw material. At the same time, when the linkage shaft 9 rotates, it drives the stirring paddle 10 to rotate rapidly. The stirring drive of the stirring paddle 10 fully stirs and mixes the sodium silicate raw material, so that the heated and pressurized sodium silicate is fully mixed under static pressure.

[0031] After the subsequent static pressure mixing, the discharge valve 5 is opened, and the combination of the brake shaft 6 and the stirring screw 8 is used to dynamically push out the statically pressed sodium silicate to avoid unloading blockage. Its integrated linkage performance is better and can effectively avoid material adhesion and blockage.

[0032] 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.
