Description

Technical Field

[0002] Water glass is a very important inorganic chemical raw material with a wide range of uses in various fields. It is the raw material for producing various water glass derivatives. At present, the industry mainly adopts the dry method to produce water glass. It uses quartz sand and soda ash as raw materials. After mixing them in a certain proportion, they react in a kiln to produce sodium silicate. Usually the temperature of the kiln reaches above 1200℃. At this time, the sodium silicate is in a molten state. It is then cooled by water quenching to form solid water glass. Solid water glass needs to be prepared into a solution when used.

[0003] In the industrial field, solid water glass needs to be prepared into a solution for use. In the prior art, a dissolving kettle is usually used to dissolve the water glass. Generally, the solid water glass is placed on a heat-conducting plate of the dissolving kettle and then heated with water vapor to dissolve the solid water glass. In this technical solution, the dissolving kettle is often rotated and steam is introduced while it rotates to accelerate the dissolution efficiency of the solid water glass. However, relying solely on the rotation of the dissolving kettle can easily lead to uneven distribution of the water glass, especially in large dissolving kettles. This requires the dissolving kettle to extend the processing time or increase the processing intensity, thereby reducing production efficiency and making it difficult to meet usage requirements.

[0024] See also Figures 1-6 A water glass dissolving kettle comprises a mounting frame 1, a dissolving mechanism 2 is provided on the surface of the mounting frame 1, and a transmission mechanism 3 is provided on the surface of the dissolving mechanism 2;

[0025] The dissolving mechanism 2 includes a connecting frame 201, which is fixed to the surface of the mounting frame 1. A guide rail 202 is fixed to the top of the connecting frame 201. A slider 203 is slidably connected to the surface of the guide rail 202. A dissolving kettle body 204 is fixed to the top of the slider 203. A heat conducting plate 205 is fixed to the inner wall of the dissolving kettle body 204. A rotary joint 207 is connected to the bottom of the dissolving kettle body 204. The fixed end of the rotary joint 207 is connected to an air injection pipe 208. The air injection pipe 208 passes through the connecting frame 201. A reduction motor 210 is fixed to the top of the mounting frame 1. A drive shaft 211 is fixed to the output shaft of the reduction motor 210. The drive shaft 211 passes through the interior of the dissolving kettle body 204. The drive shaft 211 is rotatably connected to the surface of the dissolving kettle body 204. A first stirring blade 212 is fixed to the surface of the drive shaft 211.

[0026] Steam can be transported to the inside of the dissolving kettle body 204 through the gas injection pipe 208 and the rotary joint 207, so that the steam can heat the heat conducting plate 205, and the heat conducting plate 205 can transfer heat to the water glass solid and the solvent. When working, the reduction motor 210 can drive the driving shaft 211 and the first stirring blade 212 to rotate. In combination with the transmission mechanism 3, during the rotation of the first stirring blade 212, the dissolving kettle body 204 can drive the slider 203 to slide together on the surface of the guide rail 202, thereby realizing the self-rotation effect of the dissolving kettle body 204. The rotation of the driving shaft 211 and the first stirring blade 212 can form a vortex in the liquid, increase the contact area between the liquid phase and the solid phase, and promote material transfer. At the same time, the slow rotation of the dissolving kettle body 204 helps to break the local concentration gradient that may be formed, further enhance the mass transfer process, and improve the dissolution rate.

[0027] The transmission mechanism 3 includes a bearing seat 301, which is fixed to the surface of the mounting frame 1. A transmission shaft 302 is fixed to the inner wall of the bearing seat 301. The transmission shaft 302 passes through the mounting frame 1. A first transmission structure is provided on the surface of the transmission shaft 302. A first bevel gear 305 is fixed to the bottom end of the transmission shaft 302. A second bevel gear 306 is meshed with the surface of the first bevel gear 305. A driving rod 304 is fixed to the inner wall of the second bevel gear 306. A second transmission structure is installed on the surface of the driving rod 304.

[0028] The bearing seat 301 is used to support the transmission shaft 302. When the drive shaft 211 rotates, the first transmission structure will drive the transmission shaft 302 to rotate, so that the transmission shaft 302 can drive the driving rod 304 to rotate normally through the cooperation of the first bevel gear 305 and the second bevel gear 306, and the driving rod 304 can drive the dissolving kettle body 204 to rotate at the same time through the second transmission structure, thereby achieving a double rotation effect, thereby shortening the time required for the complete dissolution of solid water glass, improving production efficiency and reducing energy consumption.

[0029] Furthermore, the first transmission structure on the surface of the transmission shaft 302 includes two pulleys 303, one of which is fixed to the top of the transmission shaft 302 and the other is fixed to the surface of the drive shaft 211.

[0030] When the driving shaft 211 rotates, the pulley 303 on its surface will drive the pulley 303 on the surface of the transmission shaft 302 to rotate together through the belt, thereby ensuring that when the driving shaft 211 rotates, the transmission shaft 302 can rotate synchronously.

[0031] Furthermore, the second transmission structure on the surface of the driving rod 304 includes a third bevel gear 307, which is fixed to the surface of the driving rod 304. The surface of the third bevel gear 307 is meshed with a gear ring 308, which is fixed to the surface of the dissolving kettle body 204.

[0032] When the driving rod 304 rotates, the gear ring 308 is driven to rotate via the third bevel gear 307 , and since the third bevel gear 307 is smaller than the gear ring 308 , the gear ring 308 can drive the dissolving kettle body 204 to rotate slowly.

[0033] Furthermore, the surface of the dissolving kettle body 204 is connected to a drain valve 215 and a discharge valve 216, and the top of the dissolving kettle body 204 is connected to a feeding door 217;

[0034] The drain valve 215 is used to discharge the steam under the heat conducting plate 205 and the water flow generated by steam heating. The discharge valve 216 is used to discharge the dissolved water glass. When the feeding door 217 is opened, water glass solid and solvent can be added to the inside of the dissolving kettle body 204.

[0035] Furthermore, the top of the heat conducting plate 205 is connected to two extension shells 206;

[0036] Water vapor can enter the extension shell 206 through the surface of the heat conducting plate 205, so that the extension shell 206 can also be heated, so that the water glass solid located above the dissolving kettle body 204 can also be heated, thereby making the entire water glass heated more evenly.

[0037] Furthermore, two driven shafts 213 are fixed to the top of the inner wall of the dissolving kettle body 204, and second stirring blades 214 are fixed to the surface of the driven shafts 213. The second stirring blades 214 and the first stirring blades 212 are arranged in a staggered manner.

[0038] When the dissolving kettle body 204 rotates, the dissolving kettle body 204 will drive the driven shaft 213 and the second stirring blade 214 to rotate together, so that the two driven shafts 213 can slowly rotate around the driving shaft 211. Combined with the staggered distribution of the stirring blades, a more complex flow pattern can be formed, the turbulence of the liquid can be increased, the water glass and the solvent can be more fully contacted, and the dissolution process can be accelerated.

[0039] Furthermore, the bottom position of the discharge valve 216 is higher than the top position of the heat conducting plate 205 , and the top position of the discharge valve 216 is lower than the bottom position of the third bevel gear 307 ;

[0040] This design ensures that the dissolved water glass solvent on the top of the heat conducting plate 205 can be discharged normally through the discharge valve 216, and also avoids the discharge valve 216 colliding with the third bevel gear 307 when the dissolving kettle body 204 drives the discharge valve 216 to rotate.

[0041] Furthermore, a through slot 209 is formed between the two side extension shells 206, and a discharge valve 216 is located on one side of the through slot 209;

[0042] The provision of the through grooves 209 prevents a closed space from being formed inside the extension shells 206 on both sides, thereby allowing the dissolved water glass solvent to flow into the discharge valve 216 through the through grooves 209 .

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
