Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and more specifically, to a sodium silicate continuous pressure dissolution device with uniform feeding. Background Technology

[0002] A search revealed that Chinese Patent Publication No. CN216677760U discloses "a continuous pressurized dissolution device for uniformly fed sodium silicate, comprising an L-shaped base plate and a dissolution tank and a movable box located on both sides of the L-shaped base plate. In use, this device allows personnel to inject sodium silicate into a feed pipe through the inlet, and then into the dissolution tank through a threaded feed pipe. After injecting the appropriate amount of sodium silicate, the movable box is reset, separating the outlet end of the feed pipe from the feed pipe. After separation, the cover plate is closed, placing the sealing plate in the feed pipe. The rotating column is then rotated to tightly seal the feed pipe, preventing leakage. The continuous pressurization structure allows for continuous pressurization of the dissolution tank, and the air inlet column allows for the injection of high-temperature steam into the dissolution tank, thereby increasing the solubility of sodium silicate and preventing incomplete dissolution, thus improving the practicality of the device." However, the following drawbacks still exist:

[0003] (1) In actual use, the device is not able to dissolve properly and is prone to clumping, which leads to blockage of the outlet, affecting the continuous injection of subsequent raw materials and normal production process, reducing production efficiency, and may also cause additional wear and tear on the equipment due to the accumulation of clumped material in the tank, shortening the service life of the equipment.

[0004] (2) In actual use, the device relies solely on continuous pressurization and injection of high-temperature steam to improve solubility. For sodium silicate raw materials of different batches and large particle size differences, even under pressurization and high-temperature steam, it is difficult to completely dissolve them, resulting in unstable dissolution effect and affecting the quality of the final product. Therefore, a sodium silicate continuous pressurization dissolution device with uniform feeding is proposed. Utility Model Content

[0005] The purpose of this invention is to address the problems of existing dissolving devices, which suffer from insufficient dissolution, easy agglomeration, and blockage of the discharge port, affecting the continuous injection of subsequent raw materials and normal production processes, reducing production efficiency, and potentially causing additional wear and tear on the equipment due to the accumulation of agglomerated material in the tank, thus shortening the equipment's service life. Furthermore, relying solely on continuous pressurization and injection of high-temperature steam to improve solubility is insufficient for sodium silicate raw materials of different batches and large particle size variations, even under pressure and high-temperature steam, resulting in unstable dissolution effects and affecting the quality of the final product. This invention provides a continuous pressurized dissolving device for sodium silicate with uniform feeding to solve the aforementioned problems.

[0027] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0028] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0029] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0030] like Figure 1 As shown, this embodiment proposes a sodium silicate continuous pressurized dissolution device with uniform feeding, including a dissolution tank 1. The dissolution tank 1 is equipped with a dissolution component 2 for efficiently dissolving sodium silicate and maintaining a stable dissolution state. The top of the dissolution tank 1 is equipped with a crushing component 3 for crushing large pieces of sodium silicate raw material to improve the subsequent dissolution effect. A feeding component 4 is movably installed on one side of the crushing component 3 for orderly and stably conveying sodium silicate raw material to the crushing component 3.

[0031] like Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, the dissolving assembly 2 includes a first servo motor 201 fixedly mounted on the top of the dissolving tank 1. A stirring shaft 202 is fixedly mounted on the output end of the first servo motor 201. Several stirring rods 203 are welded to the periphery of the stirring shaft 202. A feed inlet 204 is provided on the top of the dissolving tank 1, and a sealing cap 205 is provided on the top of the feed inlet 204. A discharge outlet 206 is provided on the periphery of the dissolving tank 1, and a solenoid valve 207 is provided on the periphery of the discharge outlet 206. A heating plate 208 is provided at the bottom of the dissolving tank 1, and an electric heating wire 209 is fixedly mounted inside the heating plate 208. An electric heating wire 210 is provided on the periphery of the inside of the dissolving tank 1. A temperature sensor 211 is installed on the periphery of the dissolving tank 1. The temperature sensor 211 is a Pt100 platinum resistance thermometer, model WZP- 230. The temperature controller is electrically connected to heating wire 1 209 and heating wire 210. A pressure gauge 212 and a safety valve 213 are installed on the top of the dissolving tank 1. Three scrapers 1 214 are welded to the bottom of the stirring shaft 202, and the bottom of the three scrapers 1 214 is in contact with the inner bottom of the dissolving tank 1. Scrapers 215 are welded to both sides of the stirring rod 203. In use, sodium silicate enters the dissolving tank 1 evenly from the feed inlet 204. The sealing cover 205 is closed to form a closed environment. The first servo motor 201 is started, which drives the stirring shaft 202 to rotate, thereby driving the stirring rod 203 and the scrapers 215. 214. The scraper 215 rotates to stir the material and prevent material residue from remaining on the wall and bottom of the dissolving tank 1. The electric heating wire 209 in the heating plate 208 and the electric heating wire 210 on the inner periphery of the dissolving tank 1 provide heating. The temperature sensor 211 monitors the temperature in real time and feeds it back to the externally connected temperature controller to accurately control the heating temperature and maintain a stable dissolving state. The pressure gauge 212 monitors the pressure inside the dissolving tank 1. The safety valve 213 ensures pressure safety. After dissolving is completed, the solenoid valve 207 opens and the material is discharged from the outlet 206. The whole process achieves efficient dissolution of sodium silicate through the synergistic effects of stirring, heating and pressure control.

[0032] like Figure 6 and Figure 7As shown, the pulverizing assembly 3 includes two fixing blocks 301 fixedly installed on the top of the dissolving tank 1. A pulverizing chamber 302 is fixedly installed on the top of each fixing block 301. A feed hopper 303 is located on the top of the pulverizing chamber 302. A second servo motor 304 is fixedly installed on one side of the pulverizing chamber 302. A first rotating shaft 305 is fixedly installed at the output end of the second servo motor 304. A first gear 306 is fixedly installed around the periphery of the first rotating shaft 305. Two gears are fixedly rotating inside the pulverizing chamber 302. The second rotating shaft 307 has a second gear 308 fixedly installed on its periphery. The second gear 308 meshes with the first gear 306. A crushing roller 309 is fixedly installed on the periphery of each of the two second rotating shafts 307. A discharge port 310 is provided on one side of the crushing box 302. A solenoid valve 311 is installed on the periphery of the discharge port 310. A connecting pipe 312 is connected to the periphery of the discharge port 310. The end of the connecting pipe 312 away from the discharge port 310 passes through the sealing cover 205 and connects to the dissolving tank 1. Due to silicon... The sodium silicate raw material has a large particle size, resulting in a small contact area with the solvent in dissolving tank 1, which leads to a slow dissolution rate. During use, the sodium silicate raw material to be pulverized is placed into the feed hopper 303, and then enters the pulverizing chamber 302. The second servo motor 304 is started, and its output drives the first rotating shaft 305 to rotate. The first gear 306 fixed on the first rotating shaft 305 rotates accordingly. Since the first gear 306 meshes with two second gears 308, the rotation of the first gear 306 drives the two second gears 308 to rotate. 8. The synchronous reverse rotation causes the two second rotating shafts 307 to rotate, and the crushing rollers 309 on the second rotating shafts 307 also rotate. The crushing rollers 309 forcefully crush the sodium silicate raw material entering the crushing box 302. After crushing, the second solenoid valve 311 is opened, and the crushed raw material enters the dissolving tank 1 from the discharge port 310 through the connecting pipe 312 and through the sealing cover 205. This provides raw material of suitable particle size for the subsequent dissolution process in the dissolving tank 1, ensuring that the sodium silicate can be dissolved more efficiently and uniformly in the dissolving tank 1.

[0033] like Figure 4 As shown, a feeding housing 401 is movably installed on one side of the feeding assembly 4. A conveyor belt 402 is fixedly installed on the top of the feeding housing 401, and a bracket 403 is fixedly installed on the bottom of the feeding housing 401. Six casters 404 are fixedly installed on the bottom of the bracket 403. In use, the feeding assembly 4 is placed in a suitable position, and the six casters 404 make the feeding housing 401 move flexibly and adjust its position. The sodium silicate raw material to be fed is placed on the conveyor belt 402. The conveyor belt 402 rotates, driving the raw material towards the feed hopper 303. Finally, the raw material enters the subsequent processing stage through the feed hopper 303. The bracket 403 provides stable support for the feeding housing 401, ensuring the smooth operation of the conveyor belt 402 and ensuring the continuous and stable delivery of the raw material to meet the feeding requirements of the production process.

[0034] like Figure 7 As shown, a lid 5 is hinged to the top of the feed hopper 303. A handle 6 is fixedly installed on one side of the lid 5. When in use, hold the handle 6 on one side of the lid 5 and pull it upward. Because the lid 5 is hinged to the top of the feed hopper 303, the lid 5 will rotate around the hinge point to open. At this time, sodium silicate raw material can be put into the feed hopper 303. After the material is put in, hold the handle 6 and pull it downward to make the lid 5 rotate in the opposite direction around the hinge point to close the lid back to the top of the feed hopper 303, thus closing the crushing box 302. This design can effectively prevent the raw material in the feed hopper 303 from being disturbed by the external environment.

[0035] like Figure 4 As shown, a baffle 7 is fixedly installed on the top of the feeding housing 401, and a guide block 8 is fixedly installed on the side of the feeding housing 401 near the feeding hopper 303. In use, the feeding housing 401 is moved to a suitable position so that the guide block 8 is aligned with the feeding hopper 303. The sodium silicate raw material is conveyed by the conveyor belt 402. The baffle 7 can prevent the raw material from spilling during the conveying process. The raw material slides down the feeding housing 401, and the guide block 8 plays a guiding role, allowing the raw material to fall accurately into the feeding hopper 303 and then enter the subsequent processing equipment. This design ensures stable and accurate delivery of the raw material, avoids raw material waste, and improves the efficiency of the feeding process.

[0036] like Figure 7 As shown, the top of the dissolving tank 1 is provided with a feeding port 9, and the top of the feeding port 9 is provided with a sealing cap 10. When in use, if it is necessary to add some special raw materials or additives that are inconvenient to be added into the dissolving tank 1 through the conventional feeding process, the sealing cap 10 on the top of the feeding port 9 can be opened manually, the material can be poured into the dissolving tank 1 from the feeding port 9, and then the sealing cap 10 can be closed and the seal can be ensured to be good. This can not only meet the special feeding requirements, but also prevent heat loss and gas leakage in the tank during the dissolving process, and maintain the stability of the dissolving environment.

[0037] like Figure 7 As shown, the bottom of the dissolving tank 1 is fixedly equipped with four support legs 11. When in use, the four support legs 11 are firmly fixed to the bottom of the dissolving tank 1, which can evenly distribute the weight of the dissolving tank 1 and the materials and solutions inside the dissolving tank 1, providing reliable support for the dissolving tank 1, ensuring that the dissolving tank 1 remains stable during operation, and avoiding the normal operation of internal stirring, heating and other dissolving processes due to shaking or tilting.

[0038] Specifically, in use, this uniformly fed sodium silicate continuous pressure dissolution device works as follows: Sodium silicate enters the dissolution tank 1 uniformly through the inlet 204, and the sealing cover 205 is closed to form a sealed environment. The first servo motor 201 is started, driving the stirring shaft 202 to rotate, which in turn rotates the stirring roller 203 and scrapers 214 and 215, stirring the material and preventing material residue from remaining on the walls and bottom of the dissolution tank 1. The heating wire 209 in the heating plate 208 and the heating wire 210 on the inner periphery of the dissolution tank 1 provide heating. The temperature sensor 211 monitors the temperature in real time and feeds it back to the externally connected temperature controller to accurately control the heating temperature and maintain a stable dissolution state. The pressure gauge 212 monitors the pressure inside the dissolution tank 1, and the safety valve 213 ensures pressure safety. After dissolution is completed, the solenoid valve 207 opens, and the material is discharged from the outlet 206. The entire process achieves efficient dissolution of sodium silicate through the synergistic effects of stirring, heating, and pressure control. Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown), the sodium silicate raw material to be crushed is placed into the feed hopper 303, and then enters the crushing chamber 302. The second servo motor 304 is started, and the output end of the second servo motor 304 drives the first rotating shaft 305 to rotate. The first gear 306 fixed on the first rotating shaft 305 rotates accordingly. Since the first gear 306 meshes with the two second gears 308, the rotation of the first gear 306 will drive the two second gears 308 to rotate synchronously in opposite directions, thereby causing the two second rotating shafts 307 to rotate. The crushing rollers 309 on the second rotating shafts 307 also rotate accordingly. The crushing rollers 309 powerfully crush the sodium silicate raw material entering the crushing chamber 302. After crushing, the second solenoid valve 311 is opened, and the crushed raw material enters the dissolving tank 1 from the discharge port 310 through the connecting pipe 312 and through the sealing cover 205. This provides raw material of suitable particle size for the subsequent dissolution process in the dissolving tank 1, ensuring that the sodium silicate can be dissolved more efficiently and uniformly in the dissolving tank 1 (e.g., Figure 6 and Figure 7 (As shown).

[0039] All technical features in this embodiment can be freely combined according to actual needs.

[0040] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
