Abstract
Description
Technical Field
[0001] This application relates to the technical field of silica sol production equipment, and in particular to a silica sol reaction kettle device with automatic temperature adjustment. Background Art
[0002] Silica sol is a dispersion of nano-silica with a particle size in the range of 1-100 nanometers in water or other organic solvents, and is widely used in fields such as precision casting, refractory materials, coatings, textiles, and precision polishing. The domestic silica sol production technologies mainly include the ion exchange method and the silicon powder hydrolysis method. The production process of the silicon powder hydrolysis method is mainly to add water to the reaction kettle, add an alkaline catalyst, heat up to a suitable temperature, then add silicon powder, and make the silicon powder undergo hydrolysis under the catalysis of alkali to generate silicic acid. The silicic acid further undergoes a polymerization reaction to generate silicon dioxide nanoparticles. The reaction continues for a certain period of time. After the silicon powder basically reacts completely, the reaction mixture is cooled, and finally filtered by a plate and frame filter press to remove the unreacted silicon powder. The filtrate obtained is silica sol. Finally, the low-concentration silica sol is subjected to ultrafiltration and concentration treatment to obtain the silica sol finished product.
[0003] The existing silica sol reaction kettle device generally includes a polycondensation kettle body. There are multiple chemical addition pipelines on the polycondensation kettle body, and a stirrer is also provided on the polycondensation kettle body to achieve sufficient stirring and mixing of the solution inside the polycondensation kettle body. Finally, a discharge pipeline is connected to the bottom of the polycondensation kettle body. And according to production requirements, the temperature inside the polycondensation kettle body needs to be controlled. The general control method is to add electric heating tubes inside, and the electric heating tubes are connected to a constant temperature controller. After the constant temperature controller is connected to the power supply, it can realize the constant temperature heating of the electric heating tubes. By contacting the electric heating tubes with the liquid material, the temperature is transferred and the temperature of the liquid material is increased.
[0004] However, when adding additives midway, for example, when adding water, a stabilizer, a silicic acid solution and other added materials midway, the originally uniform temperature will be locally lowered due to the addition of local materials. Although the fluid can finally achieve temperature equalization through the way of thermal diffusion by the electric heating tubes, the efficiency is low, which is very unfavorable for high-efficiency production.
[0005] The problem to be solved is: how to improve production efficiency and overcome the problem of slow temperature control efficiency during the midway feeding process. Summary of the Utility Model

It should be noted that, without conflict, the following embodiments and the features in the embodiments can be combined with each other.
[0023] It should be noted that the diagrams provided in the following embodiments only illustrate the basic concept of the present application in a schematic manner. The diagrams only show the components related to the present application, rather than being drawn according to the number, shape, and size of the components in actual implementation. The type, quantity, and ratio of each component in actual implementation can be changed arbitrarily, and the component layout type may also be more complex.
[0024] The following will further describe the specific embodiments of the present application in conjunction with the accompanying Figures 1-3 drawings. Embodiment 1
[0025] An automatically temperature-controlled silica sol reactor device disclosed in an embodiment of the present application includes a polycondensation kettle main body 1, and there are multiple chemical addition pipelines 2 on the polycondensation kettle main body 1. In Figure 1 this case, the chemical addition pipeline 2 can be a water addition pipeline treated by a water treatment device, or a stabilizer can be added. The stabilizer can select different stabilizer storage tanks according to requirements, as well as the chemical addition pipeline 2 for silicic acid. Others will not be elaborated here. Here, it is to illustrate the diversification of the chemical addition pipeline 2, so that the mixed materials require efficient temperature control and stirring.
[0026] Combined with Figure 1 and Figure 2 as shown, a stirrer 3 is fixedly installed in the middle of the top of the polycondensation kettle main body 1. The stirrer 3 includes a driving motor 31, a coupling 32, and a stirring rod 33. The driving motor 31 provides rotational power to drive the stirring rod 33 to rotate. The coupling 32 facilitates the installation, disassembly, and maintenance between components. The driving motor 31 is connected to the stirring rod 33 through the coupling 32. The stirring rod 33 includes a control box 331 and a stirring tube 332. The control box 331 can protect the circuit board, and the circuit is Figure 3 the built-in battery, wireless receiving module 51, first processor module 6, temperature control module 7, etc. in
[0027] The stirring tube 332 is hollow and internally provided with a heating wire 333 (electric heating resistance wire). The heating wire 333 can generate heat by being energized. By controlling the current magnitude (power) of the heating wire 333, the constant temperature heating of the heating wire 333 can be controlled. This constant temperature heating has been popularized in the prior art.
[0028] Combined with Figure 3 as shown, the heating wire 333 is connected to the control box 331. An internal power supply 4, a wireless receiving module 51, a first processor module 6, and a temperature control module 7 are arranged in the control box 331. The internal power supply 4 provides working power. The wireless receiving module 51 is used to pair with a wireless transmitting module 52 and receive the temperature control signal from the wireless transmitting module 52. The first processor module 6 is connected between the wireless receiving module 51 and the temperature control module 7. The temperature control module 7 is connected to the heating wire 333. The first processor module 6 controls the activation of the temperature control module 7 according to the temperature control signal. After the temperature control module 7 is activated, it controls the constant temperature heating of the heating wire 333.
[0029] The built-in power supply 4 can be a built-in lithium battery as the power source. When charging is required, the built-in power supply 4 (lithium battery module) can be replaced. The wireless transmission module 52 and the wireless reception module 51 have multiple examples. For example, a Bluetooth transmission module and a Bluetooth reception module using Bluetooth communication can also be used through a Wi-Fi module, a LoRa module, a ZigBee module, etc. The first processor module 6 here can be a single-chip microcomputer and other microprocessor modules, such as DSP28335, etc. What is used here is to transmit and process the temperature control signal of the wireless reception module 51. The constant temperature control module 7 controls a constant current to control the power, that is, it can control the heating temperature of the heating wire 333.
[0030] Thus, after the multi-channel chemical addition pipeline 2 adds materials from the upper end, when the driving motor 31 works, it can drive the stirring rod 33 to rotate and stir through the coupling 32. Thus, while the materials can be mixed, since the stirring rod 33 is internally provided with a heating wire 333 and is powered by the built-in power supply 4, the heating wire 333 can assist in heating, so that temperature transfer occurs while stirring, thereby quickly and evenly raising the temperature of the stirred material and improving the efficiency. Since it is inside the polycondensation kettle main body 1, for the sake of easy control, a wireless communication method is adopted to achieve wireless control, which is convenient and practical. Embodiment 2
[0031] On the basis of implementing the above solution, further optimization can be carried out. For the convenience of maintenance, the control box 331 includes a box body 334 and a maintenance door 335. The maintenance opening 336 on the box body 334 is hinged to the maintenance door 335, and the maintenance door 335 closes the box body 334. Figure 2 As can be seen, in an example of the control box 331, it can be a rectangular mechanism, a square maintenance opening 336 can be opened on the side, and the maintenance door 335 is rotationally connected through a hinge. The maintenance door 335 can be flipped upward to take and place the circuit board, that is, to replace the internal built-in battery, etc.
[0032] For the convenience of assembly, the control box 331 is located at the upper end of the stirring tube 332, and the inner cavity of the control box 331 is communicated with the hollow upper end of the stirring tube 332 for the heating wire 333 to pass through. In this way, the heating wire 333 can pass through the stirring tube 332.
[0033] In order to isolate the communicating inner cavity of the control box 331 and the stirring tube 332, a sealing plug 8 is also provided at the upper end of the stirring tube 332. The heating wire 333 passes through the sealing plug 8 and is fixed to the sealing plug 8 with glue. The sealing plug 8 is fastened at the port of the stirring tube 332. The sealing plug 8 is a rubber block. Such a structure is also very convenient for disassembly and assembly.
[0034] To improve the stirring efficiency, a branch pipe 337 is provided at the lower part of the stirring pipe 332. A branch heating wire 333 is provided on the heating wire 333 for being arranged on the branch pipe 337. An iron bead 338 is fixed at the end of the branch heating wire 333. A magnet 339 is fixed at the outer end of the branch pipe 337, and the magnet 339 adsorbs the iron bead 338. During stirring, the material generates centrifugal force, and the iron bead 338 also generates centrifugal force, which can abut against the end of the branch pipe 337, and the outer side of the end of the branch pipe 337 is further adsorbed by the magnet 339. Embodiment III
[0035] Reference Figure 3 As shown in the figure, to further optimize the above embodiment, the wireless transmission module 52 paired with the wireless reception module 51 can also be connected to the second processor module 9. The second processor module 9 is connected to the temperature sensor 10. The temperature sensor 10 is installed at the bottom of the polycondensation kettle body 1. The temperature sensor 10 feeds back the temperature signal to the second processor module 9, and the second processor module 9 sends the temperature control signal through the wireless transmission module 52. The second processor module 9 is also connected to a drive module 11. The second processor module 9 enables the drive motor 31 through the drive module 11, and the drive module 11 is connected to the drive motor 31 to adjust the speed of the drive motor 31. The drive module 11 performs forward rotation drive or reverse rotation drive on the drive motor 31.
[0036] The temperature sensor 10 is arranged at the bottom and can collect the temperature of the discharge port. There are sampling points and a discharge pump on the pipeline at the bottom of the polycondensation kettle body 1. The discharge pump is used to provide power to output silica sol. The second processor module 9 is also the same in principle, and can be a microprocessor or a single-chip microcomputer. Through this circuit module, the forward and reverse rotation and speed adjustment of the drive motor 31 can be realized, and the reaction efficiency can be improved.
