[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a water washing and filtration device for the production of triethylamine hydrochloride from vinylene carbonate, including a housing;

[0024] The housing includes a first filter chamber 1, a second filter chamber 3 and a washing chamber 7. A drive motor 10 is installed on the top of the first filter chamber 1, and a dynamic electromagnetic adjustment component 8 is connected to the output end of the drive motor 10.

[0025] The dynamic electromagnetic adjustment assembly 8 includes a drive gear 81, which is connected to the output end of a drive motor 9. An external gear 82 is meshed with the side end of the drive gear 81. A rotating collar 83 is sleeved inside the external gear 82. A connecting rod 84 is fastened to the outer wall surface of the rotating collar 83. A magnetic field controller 85 is connected to the side end of the connecting rod 84. An electromagnetic coil control chamber 86 is installed at the bottom of the magnetic field controller 85. An electromagnetic intensity regulator 87 is installed at the bottom of the electromagnetic coil control chamber 86. A microprocessor controller 88 is installed on the side end of the electromagnetic intensity regulator 87. A short connecting post 89 is fastened to the side end of the microprocessor controller 88. An annular groove rail frame 890 is slidably connected to the side end of the short connecting post 89. The annular groove rail frame 890 is sleeved and connected to the bottom of the outer side of the washing chamber 7.

[0026] A first pretreatment filter membrane 2 is installed at the bottom of the first filter chamber 1, and an ultrafiltration dynamic membrane 4 is installed at the bottom of the second filter chamber 3. The connection ends of the first filter chamber 1, the second filter chamber 3 and the washing chamber 7 are all connected by an electrically controlled iris valve.

[0027] In one specific scheme, a mixture containing triethylamine hydrochloride is first introduced into the first filter chamber 1 through the injection end 9. Under gravity, the mixture passes through the first pretreatment filter membrane 2 at the bottom. The first pretreatment filter membrane 2 initially intercepts larger particles of impurities, such as unreacted solid raw materials and polymerization products, achieving preliminary filtration and reducing the burden on subsequent filtration steps. The solution after preliminary filtration in the first filter chamber 1 enters the second filter chamber 3. At this time, the dynamic electromagnetic adjustment component 8 begins to function, causing the microprocessor controller 88 to send control commands according to a preset program, controlling the operation of the magnetic field controller 85 and the electromagnetic intensity regulator 87. This causes the electromagnetic coil control chamber 86 to generate a magnetic field of specific intensity and variation. This magnetic field acts on the solutions in the first filter chamber 1, the second filter chamber 3, and the washing chamber 7, changing the movement and distribution of ions in the solution, promoting the interaction between triethylamine hydrochloride and water, improving the washing effect, and further removing impurities and soluble by-products. Simultaneously, in the above... During operation, the microprocessor controller 88 sends new control commands to the drive motor 10, causing the drive motor 10 to drive the drive gear 81 to rotate. Through the transmission of the external gear 82, the rotating collar 83, and the connecting rod 84, the magnetic field controller 85 and other components move slowly in a circular motion around the washing chamber 7, ensuring the uniformity and comprehensiveness of the magnetic field effect. Then, the solution that has passed through the second filtration chamber 3 enters the washing chamber 7 through the electronically controlled iris valve and undergoes deep filtration by the ultrafiltration dynamic membrane 4 at the bottom. This allows the ultrafiltration dynamic membrane 4 to accurately intercept tiny particulate impurities, colloidal substances, and trace amounts of triethylamine hydrochloride that have not been completely removed by the water wash, ensuring that the filtered solution reaches a high purity standard and meets the requirements of subsequent production processes. By acting on the solution with a dynamically changing magnetic field, the washing effect and impurity removal efficiency can be significantly improved, enhancing the operational stability of the device and the reliability of the filtration effect. Furthermore, it forms a multi-stage dynamic filtration modular structure, effectively intercepting impurities of different particle sizes and reducing the problem of easy clogging.

[0028] Example 2: Figure 1 - Figure 4 As shown, the side end of the ultrafiltration dynamic membrane 4 is connected to an electromagnetic liquid delivery pipe structure 5, and the side end of the washing chamber 7 is equipped with an observation window 6.

[0029] The bottom of the washing chamber 7 is connected to the discharge end 12 and the waste discharge end 13.

The filtered pure solution is discharged through the discharge end 12 for collection and used as qualified raw material for subsequent production process. During the filtering process, the impurities intercepted on the surface of the filtration dynamic membrane 4 and the concentrated pollutants are regularly discharged through the waste discharge end 13 for subsequent treatment.

[0034] The method for using the device and the working principle are as follows: firstly, the mixed solution containing triethylamine hydrochloride is introduced into the first filter chamber 1 through the injection end 9, under the action of gravity, the mixed solution passes through the first pretreatment filter membrane 2 at the bottom, the driving motor 10 drives the stirring rotating structure to start low-speed rotation and gradually accelerate the stirring, so that the mixed solution is uniformly dispersed, the solid particle precipitation and agglomeration are prevented, the filtering efficiency and service life of the first pretreatment filter membrane 2 are improved, the first pretreatment filter membrane 2 preliminarily intercepts impurities such as unreacted solid raw materials and polymerization products, realizes preliminary filtration, and reduces the burden of subsequent filtration steps, the solution after the preliminary filtration in the first filter chamber 1 enters the second filter chamber 3, at this time, the dynamic electromagnetic adjusting assembly 8 starts to play a role, the micro-processing controller 88 sends control instructions according to the preset program, controls the operation of the magnetic field controller 85 and the electromagnetic intensity adjuster 87, so that the electromagnetic coil control chamber 86 generates a magnetic field with specific strength and changes, the magnetic field acts on the solution in the first filter chamber 1, the second filter chamber 3 and the water washing chamber 7, so that the motion state and distribution of ions in the solution can be changed, the interaction between triethylamine hydrochloride and water is promoted, the water washing effect is improved, and impurities and soluble by-products are further removed, at the same time, in the above operation process, the micro-processing controller 88 sends new control instructions to the driving motor 10, so that the driving motor 10 drives the driving gear 81 to rotate, through the transmission of the external gear 82, the rotating sleeve ring 83 and the connecting rod 84, the magnetic field controller 85 and other components make a slow circular motion around the water washing chamber 7, to ensure the uniformity and comprehensiveness of the magnetic field action, then the solution after the second filter chamber 3 passes through the electrically controlled iris valve and enters the water washing chamber 7, and is deeply filtered by the ultrafiltration dynamic membrane 4 at the bottom, so that the ultrafiltration dynamic membrane 4 can accurately intercept small particle impurities, colloidal substances and a small amount of triethylamine hydrochloride which is not completely removed by water washing, to ensure that the filtered solution reaches a high purity standard and meets the requirements of subsequent production processes, the solution is acted on by the dynamically changing magnetic field, which can significantly improve the water washing effect and impurity removal efficiency, improve the operation stability of the device and the reliability of the filtering effect, and form a multi-stage dynamic filtering modular structure, effectively intercept impurities in different particle size ranges and reduce the problem of easy blockage, wherein the operator observes the state of the solution in the water washing chamber 7, such as color and turbidity, through the observation window 6 in real time, the pure filtered solution is discharged through the discharge end 12 for collection as qualified raw materials for subsequent production processes, and the impurities intercepted on the surface of the ultrafiltration dynamic membrane 4 and the concentrated pollutants are periodically discharged through the waste discharge end 13 for subsequent treatment.
