[0002] In the production process of silane coupling agents, filtration is the key link to remove reaction by-products, unreacted raw materials and impurities. At the same time, its reaction by-products and impurities are not produced all at once, but are continuously generated during the production process.

During this filtration process, due to the different particle sizes of impurities, large particles of impurities easily cause clogging of small-pore filters, and some impurities are colloids, which increases the probability of filtration clogging. At the same time, the water flow pressure of traditional backwashing equipment is constant, which makes it difficult to remove deep impurities in the filter, resulting in low backwashing efficiency.

[0015] The present invention provides a filtering and processing device for the production of silane coupling agents. It has the following beneficial effects:

[0016] 1. Through the cooperation of the double-layer filtering device, the reflux pipe and the pressurizing device, the impurities continuously precipitated during the production process are continuously filtered, thereby improving the filtering efficiency. The pore size of the first filter screen is larger than that of the second filter screen, so that the impurities with larger particle sizes remain in the inner filter cylinder, and the impurities with smaller particle sizes remain in the outer filter cylinder, thus avoiding the blockage of the filter screen with a small pore size by the impurities with large particle sizes. The stirring motor drives the stirring blades to rotate, and at the same time drives the limiting ring to rotate through the transmission component, so that the inner filter cylinder rotates. At this time, the cylindrical frame two continuously slides across the inner side wall of the first filter screen, scraping the impurities adhering to the inner side wall of the first filter screen, further reducing the blockage probability of the first filter screen.

[0017] 2. The process of realizing the reflux of the mixed raw materials through the pressurizing device enables the raw materials to be continuously discharged and refluxed, so that the position of the raw materials in the mixing tank 1 changes greatly continuously, further improving the mixing effect.

[0018] 3. By adopting a piston-type pressurizing device driven by an electric push rod, pulsed water pressure is generated. Combined with the flipping and pouring of the mixing tank, the anti-flushing efficiency and effect are greatly improved. At the same time, the first filter screen and the second filter screen are prepared by using shape memory alloy, and the dynamic contraction and expansion of the pore size are realized through the austenite-martensite phase transformation triggered by temperature, greatly increasing the probability of impurities detaching from the filter screen, and thus greatly improving the anti-flushing effect.

Detailed Embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to the attached Figure 1 - attached Figure 8, an embodiment of the present invention provides a filtering and treatment device for the production of silane coupling agents, including a stirring tank 1 with a self-heating function. A double-layer filtering device is arranged inside the stirring tank 1. The inner filtering aperture of the double-layer filtering device is larger than the outer filtering aperture. A stirring motor 2 is arranged at the top of the stirring tank 1. The stirring motor 2 is used to drive the stirring paddle 3 to rotate and drive the inner layer of the double-layer filtering device to rotate through a transmission component. The inner filtering part and the outer filtering part of the double-layer filtering device are in contact with each other. A discharge pipe 4 is arranged at the discharge port at the bottom of the stirring tank 1. A reflux pipe 5 is communicated in the middle of the discharge pipe 4. Electric control valves are arranged on the pipe bodies of both of them. The upper opening of the reflux pipe 5 extends into the feeding port of the stirring tank 1. The bottom of the discharge pipe 4 is communicated with a horizontal pipe 6. Pressurizing devices are respectively arranged on both sides of the horizontal pipe 6. The pressurizing devices are used to drive the material to return to the stirring tank 1 through the reflux pipe 5 and at the same time used to increase the washing water pressure for backwashing. A turning mechanism is arranged at the bottom of the stirring tank 1. When backwashing is carried out, the turning mechanism drives the stirring tank 1 to turn over and pour, so that the washing water and impurities during the backwashing process are discharged from the feeding port of the stirring tank 1.

[0030] The double-layer filtering device includes an outer filtering cylinder 7 and an inner filtering cylinder 8. The outer filtering cylinder 7 includes a cylindrical frame one 701. A filter screen one 702 is coated and fixedly connected inside the cylindrical frame one 701. The outer wall of the cylindrical frame one 701 is fixedly connected to the inner wall of the stirring tank 1, so that a space is formed between the filter screen one 702 and the inner wall of the stirring tank 1. The inner filtering cylinder 8 is sleeved inside the outer filtering cylinder 7. The inner filtering cylinder 8 includes a limiting ring 801. The bottom wall of the limiting ring 801 is fixedly connected with a cylindrical frame two 802. A filter screen two 803 is coated and fixedly connected inside the cylindrical frame two 802. The outer wall of the cylindrical frame two 802 is smoothly arranged and is in contact with the filter screen one 702. The bottom wall of the limiting ring 801 is rotatably connected to the top wall of the stirring tank 1, and an outer gear 804 is embedded and fixedly connected in the middle of the limiting ring 801. The aperture of the filter screen one 702 is larger than the aperture of the filter screen two 803.

[0031] A material output pipe 30 and a backwashing pipe 31 are also respectively communicated on the horizontal pipe 6. The material output pipe 30 is used to output the filtered material. The backwashing pipe 31 is connected to a backwashing device. Electric control valves are arranged on the pipe bodies of the material output pipe 30 and the backwashing pipe 31.

[0032] When producing silane coupling agent, the raw materials are injected into the stirring tank 1, and then the stirring blades 3 are driven by the stirring motor 2 to stir and mix the raw materials. At this time, the impurities in the mixed raw materials are filtered by the double-layer filtering device and then output through the discharge pipe 4. The mixed raw materials driven by the pressurizing device are refluxed into the stirring tank 1 again and filtered by the double-layer filtering device again. This process is repeated, so that the continuously precipitated impurities during the production process are continuously filtered, and finally a highly pure silane coupling agent is obtained. The double-layer filtering device adopts an outer filtering cylinder 7 and an inner filtering cylinder 8 which are sleeved with each other. Among them, the cylindrical skeleton one 701 of the outer filtering cylinder 7 is fixedly connected to the inner wall of the stirring tank 1. At the same time, a first filter screen 702 is covered inside the cylindrical skeleton one 701, so that the cylindrical skeleton one 701 is located between the inner wall of the stirring tank 1 and the first filter screen 702. At the same time, the cylindrical skeleton one 701 is of a hollow structure, so that a space is formed between the inner wall of the stirring tank 1 and the first filter screen 702. The mixed raw materials in the outer filtering cylinder 7 enter the stirring tank 1 through this space after being filtered by the first filter screen 702. Similarly, the inner filtering cylinder 8 is sleeved inside the outer filtering cylinder 7. The cylindrical skeleton two 802 of the inner filtering cylinder 8 is in contact with the inner side of the first filter screen 702. At the same time, a second filter screen 803 is covered on the inner wall of the cylindrical skeleton two 802. Then a space is also formed between the first filter screen 702 and the second filter screen 803 under the support of the cylindrical skeleton two 802. The mixed raw materials in the inner filtering cylinder 8 enter the outer filtering cylinder 7 through this space after being filtered by the second filter screen 803. At the same time, the aperture of the first filter screen 702 is larger than that of the second filter screen 803, so that the impurities with larger particle sizes are retained in the inner filtering cylinder 8, and the impurities with smaller particle sizes are retained in the outer filtering cylinder 7, thus avoiding the blockage of the small-aperture first filter screen 702 by the impurities with larger particle sizes. At the same time, the limiting ring 801 is rotatably connected to the top wall of the stirring tank 1. While the stirring motor 2 drives the stirring blades 3 to rotate, the limiting ring 801 is driven to rotate through the transmission component, so that the inner filtering cylinder 8 rotates. At this time, the cylindrical skeleton two 802 continuously slides across the inner side wall of the first filter screen 702, which plays a role in scraping the impurities adhering to the inner side wall of the first filter screen 702 and further reduces the blockage probability of the first filter screen 702.

[0033] At the same time, in the process of realizing the reflux of the mixed raw materials through the pressurizing device, the raw materials are continuously discharged and refluxed, so that the position of the raw materials in the stirring tank 1 changes greatly continuously, further improving the mixing effect.

[0034] It should be noted that the pressurizing device not only drives the reflux of the mixed raw materials, but also participates in the backwashing step. When backwashing, the washing water enters the horizontal pipe 6 through the backwashing pipe 31 and enters the stirring tank 1 through the discharge pipe 4 under the action of water pressure for reverse flushing to remove the residual impurities in the stirring tank 1, the outer filter cylinder 7 and the inner filter cylinder 8. Under the action of the pressurizing device, the washing water entering the horizontal pipe 6 is pressurized, thereby increasing the washing water pressure and improving the backwashing effect. At the same time, since the pressurizing device adopts the piston 21 driving method, during the reciprocating movement of the piston 21, the actual output pressure is in the form of a pulse, and the washing water in the stirring tank 1 is repeatedly disturbed. Compared with the water flow with a constant pressure, the water flow in the form of a pulse has a better washing effect.

[0035] Both the first filter net 702 and the second filter net 803 are made of shape memory alloy materials. When the stirring tank 1 is in the heating state, the first filter net 702 and the second filter net 803 are heated to trigger the pore diameter contraction state. When backwashing, the first filter net 702 and the second filter net 803 come into contact with the washing water and cool down, triggering the pore diameter expansion state.

[0036] The shape memory alloy (SMA) filter screen is an intelligent filtration technology based on the dynamic response characteristics of SMA. Its core lies in using the phase change behavior (austenite-martensite transformation) of SMA to realize the self-adaptive adjustment of the filter screen pore diameter, thereby optimizing the filtration efficiency and solving problems such as easy blockage and frequent maintenance of traditional filter materials. Specifically:

[0037] The filter screen body is made of nickel-titanium-based (Ni-Ti) shape memory alloy, and its advantages include:

[0038] It can withstand strains up to 8% without permanent deformation within the phase change temperature range, adapting to dynamic filtration scenarios.

[0039] Through thermal cycling (heating / cooling), it can present preset pore diameter morphologies at high temperature (austenite phase) and low temperature (martensite phase) respectively.

[0040] It is suitable for acidic, alkaline or high-temperature fluid environments and is corrosion-resistant.

[0041] Its manufacturing process is as follows:

[0042] Use the argon protection sintering process to prepare porous SMA filter materials, and adjust the porosity (30%-50%) and average pore diameter (10-50μm) by controlling the sintering temperature (such as 980°C) and time (8-12 hours);

[0043] Add elements such as Cu and Al to improve the phase change temperature range of the alloy to make it suitable for different application scenarios;

[0044] Coat the surface of the SMA filter screen with a pH-responsive polymer (such as a coating containing carboxyl / amino groups) to enhance the selective adsorption of heavy metal ions;

[0045] Increase the surface micro-nano structure through chemical etching or laser processing to improve the interception efficiency and anti-pollution ability.

[0046] Through the above solutions,

[0047] When the normal stirring and filtering process is carried out, the filter screen 702 contacts the mixed raw material fluid with a higher temperature with the filter screen 803, and the SMA changes from the martensite phase to the austenite phase, the pore diameter shrinks, and the interception rate of micro-particles is improved.

[0048] When the backwashing step is carried out, the filter screen 702 contacts the cooling rinsing water with the filter screen 803, and the martensite phase is restored, the pore diameter expands, the fluid resistance is reduced and it is convenient for backwashing.

[0049] A cover plate 9 is arranged at the upper opening of the stirring tank 1. The cover plate 9 is fixedly connected to the outer wall of the stirring tank 1 through the side support 10. The top wall of the cover plate 9 is fixedly connected with a mounting frame 11. The outer wall of the stirring motor 2 is fixedly connected to the top of the mounting frame 11. The top end of the rotating shaft of the stirring paddle 3 penetrates through the cover plate 9 and is rotatably connected thereto. The output end of the stirring motor 2 is fixedly connected to the top end of the rotating shaft of the stirring paddle 3. The rotating shaft of the stirring paddle 3 is located on the central axis of the inner filter cylinder 8.

[0050] The stirring paddle 3 is driven to rotate by the stirring motor 2 to stir and mix the mixed raw materials in the stirring tank 1 and promote its reaction process.

[0051] At the same time, when backwashing is carried out, the flipping mechanism is used to drive the stirring tank 1 to flip and pour, so that the rinsing water and impurities in the backwashing process are discharged from the feeding port of the stirring tank 1, improving the discharge efficiency of the impurities and further enhancing the backwashing effect.

[0052] The transmission component includes a transmission shaft 12. The bottom of the transmission shaft 12 is rotatably connected to a support frame 13. The side wall of the support frame 13 is fixedly connected to the outer wall of the stirring tank 1. The top of the transmission shaft 12 is rotatably connected to a support frame 14.

The tooth ends of the gear 15 are meshed with the tooth ends of the external gear 804.

[0053] While the stirring motor 2 drives the stirring paddle 3 to rotate, the sprocket 18 drives the sprocket 16 to rotate, and then the gear 15 drives the limiting ring 801 with the external gear 804 to rotate, and finally the inner filter cylinder 8 rotates.

[0054] The pressurizing device includes a crossover cylinder 19. One end of the crossover cylinder 19 is a cylindrical structure, and the other end is a conical structure. The conical structure end is connected to the horizontal pipe 6, and a pressurizing cylinder 20 is rotatably connected to the cylindrical structure end. The central axes of the crossover cylinder 19, the horizontal pipe 6, and the pressurizing cylinder 20 coincide. A piston 21 is arranged inside the pressurizing cylinder 20. A side wall of the piston 21 is fixedly connected to an electric push rod 22. The piston 21 is driven by the electric push rod 22 to move inside the pressurizing cylinder 20. By changing the space between the piston 21 and the crossover cylinder 19, the pressure inside the horizontal pipe 6 is changed. A second base 28 is fixedly connected to the outer wall of the pressurizing cylinder 20. One side of the second base 28 is fixedly connected to the side wall of the first base 23, and the upper part of the other side is fixedly connected to a second side bracket 29. The upper part of the second side bracket 29 is fixedly connected to the outer cylinder wall of the electric push rod 22.

[0055] The piston 21 is driven by the electric push rod 22 to move inside the pressurizing cylinder 20, so that the space between the piston 21 and the crossover cylinder 19 is changed, thereby realizing the pressurizing function. Of course, according to actual needs, a two-way pressure relief valve can also be provided on the pressurizing cylinder 20 to prevent the electric push rod 22 from operating overloaded.

[0056] The flipping mechanism includes a first base 23. An arc surface 2301 is arranged on the upper part of the first base 23. An arc-shaped slideway 2302 is arranged in the arc surface 2301. A base platform 24 slides on the arc surface 2301. The bottom of the base platform 24 is embedded and slidably connected in the arc-shaped slideway 2302. Both sides of the upper surface of the base platform 24 are fixedly connected with support legs 25. The upper parts of the support legs 25 are fixedly connected to the outer wall of the mixing tank 1 through a base 26. The center of the rear side of the first base 23 is rotatably connected to a cylinder 27. The output end of the cylinder 27 is rotatably connected to the center of the base platform 24. The base platform 24 is driven by the cylinder 27 to move along the arc-shaped slideway 2302, and the central axis of the movement track of the base platform 24 coincides with the central axis of the horizontal pipe 6. The crossover cylinder 19 passes through and is fixedly connected to the lower part of the support legs 25.
