Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and more specifically, to a pilot-scale amplification preparation device for silane coupling agents. Background Technology

[0002] In the pilot-scale production of silane coupling agents, traditional processes typically rely on equipment such as synthesis reactors and distillation vessels. However, these devices are often fixed by welding, making them difficult to disassemble and requiring significant laboratory or production workshop space. Furthermore, different production stages (such as dropping, synthesis, and distillation) require separate equipment, increasing operational complexity and cost. Therefore, it is necessary to design a more flexible, efficient, and space-saving silane coupling agent preparation apparatus to meet the needs of pilot-scale production. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pilot-scale preparation device for silane coupling agents to solve the above-mentioned deficiencies.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0005] This invention relates to a pilot-scale amplification apparatus for preparing silane coupling agents, comprising a first apparatus and a second apparatus. Both the first and second apparatuses include a movable support frame on which pilot-scale equipment is mounted. The pilot-scale equipment includes a dropping tank, a synthesis vessel, a distillation column, a condenser, and a receiving tank. The distillation column and the condenser are connected by a hinged snap-fit ​​mechanism. The first and second apparatuses can be quickly assembled or disassembled according to actual needs, thereby significantly saving space. Furthermore, when distillation is not required, the synthesis vessel can be used independently, improving the utilization rate of the equipment.

[0006] Preferably, the first device is provided with a dropping tank, a synthesis vessel, and a distillation column connected in sequence. The output end of the dropping tank is connected to the synthesis vessel. The synthesis vessel is equipped with a stirring paddle. Under the control of a stirring motor, the stirring paddle stirs the material in the synthesis vessel to improve the reaction efficiency of the material. When the synthesis reaction is completed, if further purification of the product is required, the distillation system is started, and the reaction mixture is fractionated using the distillation column to remove impurities and unreacted raw materials.

[0007] Preferably, the second device is provided with a condenser and a receiving tank. The condenser is connected to the distillation column by a hinged snap-fit. The receiving tank is provided at the lower end of the condenser. The pure gas or vapor after distillation enters the condenser and is cooled into a liquid state, and then flows into the receiving tank for storage.

[0008] Preferably, the hinged buckle includes a first connecting pipe, a second connecting pipe, a corrugated pipe, and a clamp. One end of the first connecting pipe and the second connecting pipe are fixedly connected by the corrugated pipe. The first connecting pipe and the second connecting pipe can be bent through the corrugated pipe to change the angle between the first connecting pipe and the second connecting pipe. A conical ring is provided at the opposite ends of the first connecting pipe and the second connecting pipe. Conical rings are also provided on the pipes at the output end of the distillation column and the input end pipes of the condenser. The conical rings are engaged with the clamp.

[0009] Preferably, a hinge plate is fixedly connected to the opposite side of the first connecting pipe and the second connecting pipe, the first connecting pipe and the second connecting pipe are movably connected through the hinge plate, and a damper is provided at the hinge point of the hinge plate to fix the bending angle of the first connecting pipe and the second connecting pipe.

[0010] Preferably, the clamp has a conical groove that can simultaneously enclose two conical rings. The clamp has symmetrical connecting ears at both ends. The clamp is locked by bolts passing through the connecting ears. After the clamp is locked, the conical groove compresses the conical rings and pushes them toward the middle of the groove, thereby connecting the two conical rings.

[0011] Preferably, a sealing groove is provided on one side of the conical ring, and a sealing ring is provided in the sealing groove. When the clamp clamps the two conical rings at the same time, the conical rings squeeze each other and squeeze the sealing ring tightly to achieve a seal.

[0012] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0013] This invention relates to a pilot-scale amplification device for silane coupling agents. It employs a snap-fit ​​connection method, allowing for rapid assembly and disassembly of the distillation column and condenser, greatly improving the flexibility of equipment use and adapting to different production process requirements. The detachable design not only reduces space occupation when the equipment is idle but also facilitates transportation and storage. The equipment combination can be flexibly adjusted according to different stages of the production process, completing the entire process from dropping to distillation without moving a large amount of equipment, significantly improving work efficiency. The design of the conical ring and clamps, combined with the sealing ring in the sealing groove, ensures good sealing at the connection points, preventing leakage. Each component is easy to disassemble, facilitating cleaning and maintenance, and reducing long-term operating costs and complexity. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figures 1-4 This utility model discloses a pilot-scale amplification preparation device for silane coupling agents, comprising a first device 1 and a second device 2. Both the first device 1 and the second device 2 include a movable support, on which pilot-scale equipment is mounted. The equipment on the first device 1 and the second device 2 is connected by a hinged buckle 3. These two parts can be quickly assembled or disassembled according to actual needs, thereby saving a significant amount of space. Furthermore, when distillation is not required, the synthesis vessel 12 can be used independently, improving the utilization rate of the equipment.

[0022] Specifically, the first device 1 is equipped with a dropping tank 11, a synthesis vessel 12, and a distillation column 13 connected in sequence. The output end of the dropping tank 11 is connected to the synthesis vessel 12. The required reactants are accurately weighed according to the formula and added to the dropping tank 11. According to the process requirements, the material in the dropping tank 11 is slowly dripped into the synthesis vessel 12 for preliminary reaction. The synthesis vessel 12 is equipped with a stirring paddle 121. Under the control of the stirring motor, the stirring paddle 121 stirs the material in the synthesis vessel 12 to improve the reaction efficiency of the material. After the material enters the synthesis vessel 12, it undergoes a chemical reaction under the set temperature and pressure conditions to generate the target product - silane coupling agent. After the synthesis reaction is completed, if further purification of the product is required, the distillation system is started, and the reaction mixture is fractionated using the distillation column 13 to remove impurities and unreacted raw materials.

[0023] The second device 2 is equipped with a condenser 21 and a receiving tank 22. The condenser 21 is connected to the distillation column 13 by a hinge buckle 3. The receiving tank 22 is provided at the lower end of the condenser 21. The pure gas or vapor after distillation enters the condenser 21 and is cooled into a liquid state, and then flows into the receiving tank 22 for storage.

[0024] The hinged buckle 3 includes a first connecting pipe 31, a second connecting pipe 32, a corrugated pipe 33, and a clamp 34. One end of the first connecting pipe 31 and the second connecting pipe 32 are fixedly connected through the corrugated pipe 33. The first connecting pipe 31 and the second connecting pipe 32 can be bent through the corrugated pipe 33 to change the angle between the first connecting pipe 31 and the second connecting pipe 32. A hinge plate 311 is fixedly connected to the opposite side of the first connecting pipe 31 and the second connecting pipe 32 through the hinge plate 311. A damper is provided at the hinge of the hinge plate 311 to fix the bending angle of the first connecting pipe 31 and the second connecting pipe 32. A conical ring 312 is provided at one end of the first connecting pipe 31 and the second connecting pipe 32 that are opposite to each other. A conical ring 312 is also provided on the pipe at the output end of the distillation column 13 and the pipe at the input end of the condenser 21. The conical ring 312 is engaged with the clamp 34. A conical groove 341 is provided on the clamp 34. Two conical rings 312 can be wrapped in the conical groove 341 at the same time. Connecting ears 342 are symmetrically provided at both ends of the clamp 34. The clamp 34 is locked by bolts that pass through the connecting ears 342. After the clamp 34 is locked, the conical groove 341 squeezes the conical ring 312 and pushes the conical ring 312 toward the middle position of the conical groove 341, thereby connecting the two conical rings 312.

[0025] A sealing groove 313 is provided on one side of the conical ring 312, and a sealing ring 314 is provided in the sealing groove 313. When the clamp 34 clamps the two conical rings 312 at the same time, the conical rings 312 squeeze each other and squeeze the sealing ring 314 tightly to achieve a seal.

[0026] Working process: Ensure all equipment is installed on the movable support and the connecting parts of the hinge buckle 3 are correctly installed. Accurately weigh the required reactants according to the formula and add them to the dropping tank 11. Slowly drip the material in the dropping tank 11 into the synthesis vessel 12. Start the stirring motor and use the stirring paddle 121 to fully stir the material in the synthesis vessel 12 to improve the reaction efficiency and generate the target product - silane coupling agent. After the synthesis reaction is completed, if further purification of the product is required, use the distillation column 13 to fractionate the reaction mixture to remove impurities and unreacted raw materials. During this process, the angle between the first connecting pipe 31 and the second connecting pipe 32 can be fixed by adjusting the damper on the hinge plate 311 to ensure smooth material transmission. The purified gas or vapor after distillation enters the condenser 21 and is cooled into a liquid state by the receiving tank 22 set at the lower end of the condenser 21 for storage.
