Description

Technical Field

[0001] The invention relates to the technical field of sodium silicate production equipment, in particular to a continuous liquid phase reactor for sodium silicate production. Background Art

[0002] Sodium silicate, also known as water glass, can be used as one of the main raw materials in the soap industry. Adding sodium silicate to laundry soap can buffer the alkalinity of the soap, reduce the loss of laundry soap in water, enhance the washing ability and prevent the soap from becoming rancid. Sodium silicate plays a role in detergent, antiseptic and foam stabilization in synthetic detergents. It can be used as a filler in papermaking; it is used to make silicone gel and silica gel; it is used as a binder in the foundry industry to bond sand and glue to make various castings and cores that people need.

[0003] The liquid phase method is a common method for producing and processing sodium silicate. It uses quartz sand and caustic soda as raw materials, mixes them, adds them into a reactor and heats and presses them. When processing raw materials such as quartz sand and caustic soda, they need to be melted at high temperature and combined with other auxiliary materials to form sodium silicate liquid. However, due to the influence of materials, this continuous high-temperature heating method will not only cause local overheating of the equipment, which is prone to danger and safety accidents during the processing, but also the high temperature generated in this heating process is directly dissipated into the external environment, resulting in a certain amount of heat energy waste.

[0020] Working principle: When processing and producing sodium silicate, the material preheating mechanism is started first, and the staff adds the required materials into the preheating chamber of the reactor through the right diverter tube, and then the quartz sand, caustic soda and other auxiliary materials entering the preheating chamber are stored on the uppermost partition seat, and then the circulating heating fan on the reactor is started. The circulating heating fan heats the air while starting, and then the heated air enters the right diverter tube through the connecting pipe, and then the heated air enters the right diverter tube through the diverter into each preheating transverse tube after diversion. When the heated gas flows in the preheating transverse tube, it also flows on the preheating transverse tube. The heated gas flows in the preheating ring tube, and the heated gas also transfers the heat in it to the material in the preheating chamber through the tube wall while flowing in the preheating cross tube and the preheating ring tube, so that various materials in the preheating chamber are evenly preheated. Then, the air after the heat transfer is temporarily stored in the temporary storage tube on the left, so as to complete the preheating treatment of the materials in the sodium silicate production process; after the material preheating mechanism completes the preheating treatment of the quartz sand, caustic soda and other auxiliary materials in the preheating chamber, the conduction adjustment mechanism is started, and the staff controls the annular electromagnetic seat in the uppermost partition seat through the remote control device to energize, so that the annular electromagnetic seat in the moving chamber of the uppermost partition seat changes its magnetism, and the The annular electromagnetic seat 1 in the upper separator seat moving cavity after being converted into magnetic is in opposite polarity to the annular electromagnetic seat 2 on the semicircular closed plate inside it. Through the principle that like magnets repel each other and opposite magnets attract each other, the suction force generated between the annular electromagnetic seat 1 and the annular electromagnetic seat 2 drives the semicircular closed plates on both sides of the moving cavity to move toward the edge at the same time. While the semicircular closed plates move, they drive the anti-drop rods thereon to move synchronously in the plug-in cavity on the opposite side. After the semicircular closed plates move, the discharge port in the conical cavity at the bottom of the separator seat is in an open and conductive state, and then the preheated material in the preheating cavity enters the heated melting cavity at the bottom thereof for subsequent processing, thereby completing the conductive adjustment of the material. The temperature-raising reaction mechanism is then started. When the various materials that have undergone the preheating treatment enter the temperature-raising and melting chamber, the heating wire on the mounting rod is energized to generate heat, and the heat generated is conducted through the temperature-raising conduction pipe into the materials in the temperature-raising and melting chamber, thereby causing the materials in the temperature-raising and melting chamber to heat up and melt. After the state of the materials in the temperature-raising and melting chamber is converted from solid to liquid, the conduction regulating mechanism controls the discharge port in the second partition seat to conduct, thereby causing the materials in the temperature-raising and melting chamber that are converted from solid to liquid to enter the insulation reaction chamber for insulation reaction, thereby completing the temperature-raising, melting and insulation reaction treatment of the raw materials in the sodium silicate production process;When the temperature-raising reaction mechanism is started, the heat energy reflux mechanism is started. When the material entering the temperature-raising melting chamber is heated and melted, the heat generated in the temperature-raising melting chamber is absorbed by the conductive heat-absorbing layer on the annular sleeve. Then, after the conductive heat-absorbing layer absorbs the heat, part of the heat is conducted to the conductive baffle and the other part is conducted to the conductive ring plate. After absorbing the heat conducted by the annular sleeve, the conductive baffle is heated, thereby raising its own temperature. After the temperature is raised, the conductive baffle heats the gas in its airflow chamber synchronously, thereby raising the initial temperature of the air in the airflow chamber, and then the temperature is raised. The air is then preheated by circulating the circulating heating fan to preheat the material in the preheating chamber, thereby reducing the energy consumption in the preheating process and improving the preheating efficiency of the material. At the same time, after the heat absorption temperature rises, the conduction ring plate simultaneously disperses the heat absorbed by it to each conduction column at its bottom, so that the temperature of the conduction column rises synchronously after absorbing heat, and then the oil in the oil chamber is heated by the heated conduction column. At the same time, the heat absorbed by the conduction heat absorption layer is also used to heat the oil in the oil chamber. After heating, the oil in the oil chamber heats the liquid material reacting in the heat-insulating reaction chamber. Synchronous insulation treatment is carried out to prevent the reaction failure or incomplete reaction caused by heat loss or excessive temperature difference between the inside and outside of the insulation reaction chamber, thereby completing the reflux and reuse of heat energy in the melting process; then the mixing and settling mechanism is started, and after the liquid material in the insulation reaction chamber completes the insulation reaction treatment, the conduction adjustment mechanism controls the bottom partition seat to be conducted, so that the material in the insulation reaction chamber enters the mixing and settling chamber at the bottom of the reactor through the discharge port on the bottom partition seat, and then the driving motor on the reactor is started, and the rotating shaft of the driving motor drives the installation disk in the mixing and settling chamber to rotate while rotating. The mounting plate rotates synchronously, and the lifting plate drives the lifting plate therebetween to rotate synchronously. The lifting plate continuously lifts and flips the sodium silicate liquid in the mixing and settling chamber while rotating, so that the various materials in it are evenly mixed, thereby obtaining the finished sodium silicate liquid. After the mixing is completed, when the various materials are completely mixed, the mixing is stopped, and the sodium silicate liquid in the mixing and settling chamber is settled. After the settling is completed, the staff controls the electromagnetic control valve to open, so that the liquid sodium silicate in the mixing and settling chamber is discharged through the discharge pipe, thereby completing the mixing and settling treatment of the sodium silicate liquid. ;

[0021] The present invention provides a continuous liquid phase reactor for producing sodium silicate. It has the following beneficial effects:

[0022] 1. The present invention adds and sets a material preheating mechanism to perform preheating treatment on raw materials such as quartz sand and caustic soda for processing sodium silicate before processing. On the one hand, it can make the raw materials such as quartz sand and caustic soda closer to the reaction temperature when entering the reaction area, thereby reducing the time required for the material heating treatment and improving the overall reaction efficiency. On the other hand, it can also reduce the heat required to be supplemented by various raw materials during the reaction process, greatly reducing the energy consumption generated during the processing of sodium silicate.

[0023] 2. The present invention increases and sets a material preheating mechanism. Firstly, the raw materials can be heated during the material preheating stage to ensure that the raw materials contain a certain amount of heat, thereby preventing the sudden temperature change of the materials during the next processing stage from causing a degradation in their performance. Secondly, the moisture content in the raw materials can be reduced by preheating, thereby reducing the heat consumed by the raw materials due to water evaporation, and at the same time, the influence of water vapor generated by water evaporation on subsequent reactions can be avoided.

[0024] 3. The present invention increases and sets a heat reflux mechanism. On the one hand, it can absorb and utilize the overflow heat generated during the melting process of the raw materials, thereby reducing the energy consumption generated during the preheating process of the materials and improving the preheating efficiency of the materials. On the other hand, it can absorb and utilize the heat and transfer it so that the heat can be used for the thermal insulation reaction of the melted materials. This method can not only reduce the heat supplement during the thermal insulation reaction of the materials, but also prevent safety accidents caused by local overheating of the overall equipment.

[0025] 4. The present invention can not only ensure the continuous production of sodium silicate liquid with high processing efficiency by systematically and programmatically processing the sodium silicate raw materials, but also make full use of the heat energy generated in the processing and production process, thereby reducing the energy consumption of the overall equipment during use, improving the utilization rate of energy, and achieving good safety and energy-saving effects.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings of the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Please see attached Figure 1 - Attachment Figure 3 The embodiment of the present invention provides a continuous liquid phase reactor for sodium silicate production, including a reactor 1, which is used as the basic component of the overall device, for assembling and carrying various processing mechanisms and their subordinate structural parts, and the interior of which is divided into four processing chambers from top to bottom by three partition seats 14, namely, a preheating chamber 12, a heating and melting chamber 21, a heat preservation reaction chamber 20, and a mixing and settling chamber 19; a bottom frame 10, which is arranged at the bottom of the reactor 1, for supporting and fixing the reactor 1 to maintain normal operation;

[0038] Please see attached Figure 6, a material preheating mechanism, which is arranged in the preheating chamber 12, and is used to preheat and raise the temperature of quartz sand, caustic soda and other auxiliary materials entering the preheating chamber 12;

[0039] The material preheating mechanism includes a preheating transverse tube 2. A plurality of preheating transverse tubes 2 are equidistantly arranged in the middle and upper part of the reactor 1, and both ends of the preheating transverse tube 2 are connected to the reactor 1 and extend outward. A left-side temporary storage tube 3 and a right-side diversion tube 5 are respectively arranged in the middle and upper parts of both sides of the reactor 1. Both ends of the preheating transverse tube 2 are respectively connected with the interiors of the left-side temporary storage tube 3 and the right-side diversion tube 5 on the same side. A preheating ring tube 13 is arranged in the middle of the preheating transverse tube 2, and the interiors of the preheating ring tubes 13 are respectively connected with the interiors of the corresponding preheating transverse tubes 2. A circulating heating fan 11 is arranged in the middle and upper part of the rear side of the reactor 1, and the air outlet of the circulating heating fan 11 is connected with the interior of the right-side diversion tube 5 through a connecting pipe. A feeding tube 4 is arranged in the middle of the top end of the reactor 1, and the interior of the feeding tube 4 is connected with the interior of the reactor 1.

[0040] When the material preheating mechanism is started, the staff adds the required materials into the preheating chamber 12 of the reactor 1 through the right-side diverter tube 5, and then the quartz sand, caustic soda and other auxiliary materials entering the preheating chamber 12 are retained on the uppermost partition seat 14, and then the circulating heating fan 11 on the reactor 1 is started. The circulating heating fan 11 heats the air while starting, and then the heated air enters into the right-side diverter tube 5 through the connecting pipe, and then the heated gas entering into the right-side diverter tube 5 enters into each preheating transverse tube 2 after diversion.

[0041] When the heating gas flows in the preheating transverse tube 2, it also flows in the preheating ring tube 13 on the preheating transverse tube 2. When the heating gas flows in the preheating transverse tube 2 and the preheating ring tube 13, the heat in the preheating gas is transferred to the material in the preheating chamber 12 through the tube wall, so that various materials in the preheating chamber 12 are uniformly preheated. After the heat transfer is completed, the air enters the temporary storage tube 3 on the left side for temporary storage, thereby completing the preheating treatment of the materials in the sodium silicate production process.

[0042] Please see attached Figure 4 - Attachment Figure 5 , a conduction adjustment mechanism, which is arranged in the partition seat 14 and is used to adjust the conduction state of each processing chamber;

[0043] The conduction adjustment mechanism includes a movable cavity 26, a movable cavity 26 is opened in the middle of the inner side of the partition seat 14, an annular electromagnetic seat 23 is arranged in the middle of the inner wall of the movable cavity 26, a conical cavity 16 is arranged in the middle of the top end of the partition seat 14, a discharge port 22 is opened in the middle of the inner bottom end of the conical cavity 16, semicircular closing plates 25 are slidably connected on both sides of the middle of the movable cavity 26, an annular electromagnetic seat 24 is arranged in the middle of the outer wall of the semicircular closing plate 25, a plurality of plug-in cavities 28 are equidistantly arranged on the inner wall of the adjacent side of the semicircular closing plate 25, a plurality of anti-slip rods 27 are cross-fixedly connected on the inner wall of the adjacent side of the semicircular closing plate 25, and the ends of the anti-slip rods 27 extend into the corresponding plug-in cavities 28 respectively.

[0044] When the conduction adjustment mechanism is started, the staff controls the annular electromagnetic seat 1 23 in the uppermost partition seat 14 to be energized through the remote control device, so that the annular electromagnetic seat 1 23 in the moving cavity 26 of the uppermost partition seat 14 changes its magnetism. The annular electromagnetic seat 1 23 in the moving cavity 26 of the uppermost partition seat 14 after the magnetization is changed is opposite to the annular electromagnetic seat 2 24 on the semicircular closed plate 25 inside it. According to the principle that like magnets repel each other and opposite magnets attract each other, the annular electromagnetic seat 1 23 and the annular electromagnetic seat 2 24 are connected. The suction force generated drives the semicircular closing plates 25 on both sides of the moving cavity 26 to move toward the edge at the same time. While moving, the semicircular closing plates 25 drive the anti-slip rods 27 thereon to move synchronously in the plug-in cavity 28 on the opposite side. After the semicircular closing plates 25 move, the discharge port 22 in the conical cavity 16 at the bottom of the partition seat 14 is opened and connected, and then the preheated material in the preheating cavity 12 enters the heating and melting cavity 21 at the bottom thereof for subsequent processing, thereby completing the conduction and adjustment processing of the material.

[0045] After the material on the top of the uppermost separator 14 flows into the processing chamber at its bottom, the staff controls the annular electromagnetic seat 23 in the uppermost separator 14 to energize through the remote control device, so that the annular electromagnetic seat 23 in the moving chamber 26 of the uppermost separator 14 can restore its magnetism, and then the magnetism of the annular electromagnetic seat 23 and the annular electromagnetic seat 24 after the restoration of magnetism are the same, so the repulsive force generated by the sameness between the annular electromagnetic seat 1 23 and the annular electromagnetic seat 24 causes the semicircular closing plate 25 to reset, and the semicircular closing plate 25 closes the preheating chamber 12 again while resetting, so as to facilitate the subsequent material preheating treatment and material heating and melting treatment.

[0046] Please see attached Figure 8 , a temperature-raising reaction mechanism, which is arranged in the temperature-raising melting chamber 21, and is used to perform a temperature-raising reaction treatment on the material that has been preheated by the material preheating mechanism;

[0047] The temperature-raising reaction mechanism includes a temperature-raising conduction tube 15 , and a plurality of temperature-raising conduction tubes 15 are arranged in a circular array in the middle of the inner wall of the temperature-raising melting chamber 21 . A mounting rod 34 is arranged in the middle of the inner side of the temperature-raising conduction tube 15 , and both ends of the mounting rod 34 are respectively connected to the corresponding positions of the inner wall of the temperature-raising melting chamber 21 , and a heating wire 35 is arranged on the mounting rod 34 .

[0048] When the temperature-raising reaction mechanism is started, after various materials after preheating treatment enter the temperature-raising and melting chamber 21, the heating wire 35 on the mounting rod 34 is energized to generate heat, and the heat generated is conducted to the material in the temperature-raising and melting chamber 21 through the temperature-raising and conducting pipe 15, so that the material in the temperature-raising and melting chamber 21 is heated and melted. After the state of the material in the temperature-raising and melting chamber 21 is converted from solid to liquid, the conduction regulating mechanism controls the discharge port 22 in the second partition seat 14 to be conducted, so that the material in the temperature-raising and melting chamber 21 converted from solid to liquid enters the insulation reaction chamber 20 for insulation reaction, thereby completing the temperature-raising and melting and insulation reaction treatment of the raw materials in the sodium silicate production process.

[0049] Please see attached Figure 7 , a heat energy reflux mechanism, which is arranged in the middle of the outer wall of the reactor 1, and is used to reflux and reuse the heat energy generated during the temperature-raising reaction mechanism treatment process;

[0050] The heat energy reflux mechanism includes an annular sleeve 6. An annular sleeve 6 is arranged in the middle of the outer wall of the reactor 1. A conductive heat absorption layer 36 is arranged on the inner wall of the annular sleeve 6. A conductive ring plate 30 is arranged in the middle of the inner side of the annular sleeve 6. One side of the top end of the annular sleeve 6 is connected to the air inlet of the circulating heating fan 11 through a connecting pipe.

[0051] When the heat energy reflux mechanism is started, while the material entering the heating and melting chamber 21 is heated and melted, the heat generated in the heating and melting chamber 21 is absorbed by the conductive heat absorption layer 36 on the annular sleeve 6, and then after the conductive heat absorption layer 36 absorbs the heat, part of it is transmitted to the conductive baffle 33 and the other part is transmitted to the conductive ring plate 30. After absorbing the heat conducted by the annular sleeve 6, the conductive baffle 33 is heated up, thereby increasing its own temperature. After the temperature is increased, the conductive baffle 33 simultaneously heats the gas in its airflow chamber 29, thereby increasing the initial temperature of the air in the airflow chamber 29. Then, the heated air is circulated by the circulating heating fan 11 to preheat the material in the preheating chamber 12, thereby reducing the energy consumption in the preheating process and improving the preheating treatment efficiency of the material.

[0052] The heat energy reflux mechanism also includes an airflow cavity 29. The upper part of the conductive ring plate 30 and the inner wall of the annular sleeve 6 constitute the airflow cavity 29. The lower part of the conductive ring plate 30 and the inner wall of the annular sleeve 6 constitute an oil cavity 32. The interior of the oil cavity 32 is provided with insulating oil. A plurality of conductive baffles 33 are arranged in a circular array on the inner wall of the airflow cavity 29. A plurality of conductive columns 31 are arranged in a circular array in the middle of the bottom end of the conductive ring plate 30.

[0053] At the same time, after the conduction ring plate 30 absorbs heat and its temperature rises, it simultaneously disperses the absorbed heat to the conduction columns 31 at its bottom, so that the temperature of the conduction columns 31 rises synchronously after absorbing heat, and then the oil in the oil cavity 32 is heated by the heated conduction columns 31, and the oil in the oil cavity 32 is also heated synchronously by the heat absorbed by the conduction heat absorption layer 36. After the heating and temperature rise, the oil in the oil cavity 32 simultaneously insulates the liquid material reacting in the insulation reaction chamber 20, thereby preventing the reaction failure or incomplete reaction caused by heat loss or excessive temperature difference between the inside and outside of the insulation reaction chamber 20, thereby completing the reflux and reuse of heat energy in the melting process.

[0054] Please see attached Fig. 9 The mixing and settling mechanism is arranged in the mixing and settling chamber 19 and is used for mixing and settling the materials processed by the temperature-raising reaction mechanism.

[0055] The mixing and settling mechanism includes a mounting plate 18, both sides of the interior of the mixing and settling chamber 19 are rotatably connected with the mounting plates 18, a plurality of lifting plates 17 are arranged in a circular array between the mounting plates 18, a driving motor 7 is arranged at the middle and lower part of the outer wall of the reactor 1, and the output end of the driving motor 7 passes through the reactor 1 and is connected to the middle part of one side of the mounting plate 18.

[0056] When the mixing and settling mechanism is started, after the liquid material in the heat-insulating reaction chamber 20 completes the heat-insulating reaction treatment, the conduction regulating mechanism controls the bottom partition seat 14 to be conducted, so that the material in the heat-insulating reaction chamber 20 enters the mixing and settling chamber 19 at the bottom of the reactor 1 through the discharge port 22 on the bottom partition seat 14, and then the driving motor 7 on the reactor 1 is started, and the rotating shaft of the driving motor 7 drives the mounting plate 18 in the mixing and settling chamber 19 to rotate synchronously while rotating, and the mounting plate 18 drives the shoveling plate 17 therebetween to rotate synchronously while rotating, and the shoveling plate 17 continuously shovels and flips the sodium silicate prototype liquid in the mixing and settling chamber 19 while rotating, so that the various materials therein are evenly mixed, thereby obtaining a finished sodium silicate liquid.

[0057] The mixing and settling mechanism further includes a discharge pipe 8 . The bottom end of the reactor 1 is provided with the discharge pipe 8 . The interior of the discharge pipe 8 is communicated with the interior of the mixing and settling chamber 19 . The discharge pipe 8 is provided with an electromagnetic control valve 9 .

[0058] Then after the mixing is completed, when all the materials are completely mixed, the mixing is stopped, and the sodium silicate liquid in the mixing sedimentation chamber 19 is allowed to settle. After the sedimentation is completed, the staff controls the electromagnetic control valve 9 to open, so that the liquid sodium silicate in the mixing sedimentation chamber 19 is discharged through the discharge pipe 8, thereby completing the mixing and sedimentation treatment of the sodium silicate liquid.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
