Description

Technical Field

[0001] The utility model relates to the field of distillation equipment, in particular to distillation equipment for the production of modified sodium silicate. Background Technique

[0002] The distillation equipment used in the production of modified sodium silicate generally refers to the equipment for purifying and refining sodium silicate (sodium silicate or potassium silicate). In the production process of the modified sodium silicate solution, organic modifiers (such as alcohols, ketones or other organic compounds) are usually used. These organic substances have relatively low boiling points, and the separation of sodium silicate is achieved by utilizing the boiling point differences of different components of the organic modifiers.

[0003] Traditional distillation equipment for the production of modified sodium silicate often does not have an acceleration and diversion mechanism, resulting in a slow upward flow rate of the organic modifier vapor and easy loss of temperature, which affects the distillation separation effect. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides distillation equipment for the production of modified sodium silicate, which solves the problems that the distillation equipment for the production of modified sodium silicate often does not have an acceleration and diversion mechanism, resulting in a slow upward flow rate of the organic modifier vapor and easy loss of temperature.

[0005] To achieve the above object, the utility model is realized through the following technical solutions: The distillation equipment for the production of modified sodium silicate includes a distillation column. An acceleration and diversion mechanism is arranged inside the distillation column. The acceleration and diversion mechanism includes a rotating shaft, a fixed ring, connecting rods, axial flow fan blades, connecting arms and stirring blades. The lower end of the rotating shaft is rotatably connected to the bottom end inside the distillation column, the upper end of the rotating shaft penetrates through the inside of the fixed ring, four axial flow fan blades are respectively arranged on the outer side of the rotating shaft from top to bottom, each axial flow fan blade is fixedly connected to the rotating shaft, connecting arms are fixedly connected to both sides of the middle part of the rotating shaft, and a plurality of stirring blades are respectively arranged above and below between the two connecting arms and the rotating shaft.

[0006] Preferably, a plurality of connecting rods are distributed around the outer side of the fixed ring, and one end of each connecting rod away from the fixed ring is fixedly connected to the inner side of the distillation column.

[0007] Preferably, a reboiler is arranged on the outer side of the lower end of the distillation column. The reboiler is communicated with the distillation column. A gas guide pipe is fixedly connected to the outer side of the reboiler, and one end of the gas guide pipe away from the reboiler is fixedly connected to the distillation column.

[0008] Preferably, an exhaust pipe is fixedly connected to the upper end of the distillation column, and a condenser is arranged at one end of the exhaust pipe away from the distillation column.

[0009] Preferably, a drain pipe is connected to the lower end of the condenser, a reflux pipe is connected to the upper end of the condenser, and the end of the reflux pipe away from the condenser is arranged inside the distillation column.

[0010] Preferably, a booster pump is arranged at the connection position between the gas guide pipe and the distillation column.

[0011] Preferably, a water glass inlet pipe is connected to the outer side of the upper end of the distillation column.

[0012] Advantageous effects

[0013] The utility model provides a distillation device for producing modified water glass. Compared with the prior art, the following advantageous effects are achieved:

[0014] 1. In the utility model, through the arranged acceleration and diversion mechanism, during the production of water glass, the modified water glass raw material solution is introduced into the distillation column through the water glass inlet pipe. The introduced water glass solution deposits at the bottom of the distillation column and is pumped into the reboiler by a pressure pump, enabling the organic modifier in the water glass solution to vaporize and lead to the distillation column. With the upward airflow of the steam, multiple axial flow fan blades are triggered to rotate, thereby accelerating the upward flow of the organic modifier steam, reducing heat loss. After the axial flow fan blades rotate, the rotating shaft in the middle of the axial flow fan blades rotates accordingly. At this time, multiple stirring blades on the outer side of the lower end of the rotating shaft stir the water glass raw material solution accumulated at the bottom of the distillation column. The stirring effect helps prevent the precipitation of the water glass raw material at the bottom of the column, maintains the fluidity of the solution, and is beneficial to the continuous production;

[0015] 2. In the utility model, through the arranged reflux pipe, after the water glass raw material solution is heated by the reboiler, the low-boiling substances of the organic modifier in the water glass raw material solution, such as alcohols, ketones or other organic compounds, are transformed into gaseous steam form and introduced into the distillation column through the gas guide pipe. When the steam is generated in the distillation column, it forms an upward airflow and is introduced into the condenser through the exhaust pipe. After passing through the condenser, it is transformed into a liquid state and discharged through the drain pipe. A part of the steam that is not liquefied in time is reintroduced into the distillation column through the reflux pipe and re-liquefies when encountering the relatively low-temperature water glass raw material solution and is distilled again, thereby ensuring the complete separation of the organic modifier and water glass in the water glass raw material solution.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 4 , the present utility model provides two technical solutions, specifically including the following embodiments:

[0024] Embodiment 1:

[0025] The distillation equipment for the production of modified sodium silicate includes a distillation tower 1. An accelerating and guiding mechanism 2 is arranged inside the distillation tower 1. The accelerating and guiding mechanism 2 includes a rotating shaft 201, a fixed ring 202, a connecting rod 203, an axial flow fan blade 204, a connecting arm 205 and a stirring blade 206. The lower end of the rotating shaft 201 is rotatably connected to the bottom end inside the distillation tower 1. The upper end of the rotating shaft 201 penetrates through the inside of the fixed ring 202. Four axial flow fan blades 204 are respectively arranged on the outer side of the rotating shaft 201 from top to bottom. Each axial flow fan blade 204 is fixedly connected to the rotating shaft 201. Both sides of the middle part of the rotating shaft 201 are fixedly connected with connecting arms 205. There are multiple stirring blades 206 respectively above and below between the two connecting arms 205 and the rotating shaft 201. A plurality of connecting rods 203 are distributed around the outside of the fixed ring 202. One end of each connecting rod 203 away from the fixed ring 202 is fixedly connected to the inner side of the distillation tower 1. It should be noted that organic modifiers such as alcohols, ketones or other organic compounds are used in the production process of the modified sodium silicate solution. These organic substances may have relatively low boiling points, and they will be evaporated and separated from the sodium silicate solution during the distillation process.

[0026] During operation, in the process of producing glass water, the modified sodium silicate raw material solution is introduced into the distillation tower 1 through the sodium silicate inlet pipe 3. The introduced sodium silicate solution deposits at the bottom of the distillation tower 1 and is pumped into the reboiler 4 by a pressure pump, causing the organic modifier in the sodium silicate solution to vaporize and lead to the distillation tower 1. With the upward airflow of the steam, it triggers the rotation of multiple axial flow fan blades 204, thus accelerating the upward flow of the organic modifier steam. After the axial flow fan blades 204 rotate, the rotating shaft 201 in the middle of the axial flow fan blades 204 rotates accordingly. At this time, multiple stirring blades 206 on the outer side of the lower end of the rotating shaft 201 stir the sodium silicate raw material solution accumulated at the bottom of the distillation tower 1. The stirring effect helps prevent the sodium silicate raw material from precipitating at the bottom of the tower, maintaining the fluidity of the solution and facilitating continuous production.

[0027] Embodiment 2:

[0028] Based on Embodiment 1, a reboiler 4 is provided on the outer side of the lower end of the distillation tower 1. The reboiler 4 communicates with the distillation tower 1. A gas guide pipe 6 is fixedly connected to the outer side of the reboiler 4. The heating temperature of the reboiler 4 is in the same range as the boiling point of the modified organic matter in the modified sodium silicate solution. One end of the gas guide pipe 6 away from the reboiler 4 is fixedly connected to the distillation tower 1. An exhaust pipe 7 is fixedly connected to the upper end of the distillation tower 1. A condenser 5 is provided at one end of the exhaust pipe 7 away from the distillation tower 1. A drain pipe 8 is connected to the lower end of the condenser 5. A reflux pipe 9 is connected to the upper end of the condenser 5. One end of the reflux pipe 9 away from the condenser 5 is arranged inside the distillation tower 1. A booster pump 10 is provided at the connection position of the gas guide pipe 6 and the distillation tower 1. A sodium silicate inlet pipe 3 is connected to the outer side of the upper end of the distillation tower 1. After the sodium silicate raw material solution is heated by the reboiler 4, low-boiling substances of the organic modifier in the sodium silicate raw material solution, such as alcohols, ketones or other organic compounds, are transformed into gaseous steam form and introduced into the distillation tower 1 through the gas guide pipe 6, while the sodium silicate solution with a higher boiling point accumulates at the bottom of the distillation tower 1. When steam is generated in the distillation tower 1, it forms an upward airflow and is introduced into the condenser 5 through the exhaust pipe 7. After passing through the condenser 5, it is transformed into a liquid state and discharged through the drain pipe 8. A part of the steam that is not liquefied in time is re-introduced into the distillation tower 1 through the reflux pipe 9 and re-liquefies when it encounters the relatively low-temperature sodium silicate raw material solution and is distilled again, thereby ensuring the complete separation of the organic modifier and sodium silicate in the sodium silicate raw material solution.

[0029] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the application shall be included in the protection scope of the present application.
