Description

Technical Field

[0001] This utility model relates to the field of synthetic reaction equipment technology, and in particular to a microchannel continuous synthesis reactor for triethyl phosphite. Background Technology

[0002] Triethyl phosphite is an organic reagent widely used in the pharmaceutical and pesticide industries. It can also be used as a plasticizer, stabilizer, and additive and stabilizer for lubricants. In recent years, with increasingly stringent global requirements for safety and environmental protection, phosphorus-based halogen-free flame retardants made from triethyl phosphite have seen significant development.

[0003] Currently, most production of triethyl phosphite employs a batch reactor process, using ethanol and phosphorus trichloride as raw materials, with varying acid-binding agents and solvents. Solvents mainly include dichloromethane, benzene, and petroleum ether. While dichloromethane and petroleum ether have low boiling points and are easily separated from the product, they result in significant losses during production, leading to high costs. Benzene-based solvents are highly toxic and cause severe environmental pollution.

[0004] Existing equipment often suffers from problems such as difficulty in controlling the solvent synthesis ratio and difficulty in adjusting the solution flow rate, leading to a large amount of solvent waste. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a cooling and forming device for biomass fuel pellet processing, which aims to improve the problems of poor control of solvent synthesis ratio and poor adjustment of solution flow rate in existing equipment.

[0009] Furthermore, the disassembly assembly includes a snap-fit ​​seat, which is disposed on one side of the sealing ring. A pusher is slidably connected to the inner wall of the snap-fit ​​seat, and a snap-fit ​​is fixedly connected to one end of the pusher. A snap-fit ​​shaft is rotatably connected to the inner wall of the snap-fit, and a spring is fixedly connected to the outer wall of the snap-fit. A baffle is provided on the outer wall of the snap-fit.

[0010] Furthermore, the flow regulating tube is fixedly connected to one end of the microcatheter, and the buckle slides on the inner wall of the reactor.

[0011] Furthermore, the outer wall of the fixed ring is rotatably connected to the inner wall of the flow regulating pipe, and the fixed shell is fixedly connected to the outer wall of the sleeve.

The gear rotates the ball valve through the connecting shaft, thereby adjusting the size of the ball valve opening and achieving the effect of controlling the solvent synthesis ratio and adjusting the solution flow rate.

[0017] 2. In this utility model, by opening a disassembly component on the outer wall of the synthesizer, the pusher is used to rotate the buckle around the buckle shaft, compressing the spring, so that the buckle is engaged with the baffle and the sealing ring is used to seal the opening, thereby achieving the effect of fixing and sealing and convenient disassembly and cleaning.

[0029] Working principle: When the triethyl phosphite microchannel continuous synthesis reactor is needed, the liquid is first introduced into reactor 2 and reactor 23 from the flow regulating pipe 8. The synthesis reaction takes place in the microconductor 6. When the regulating component is needed, the cylinder 13 in the fixed shell 9 pushes the fixed plate 20 to drive the rack 10 to reciprocate. The rack 10 meshes with the gear 14 in the connecting sleeve 22. The reciprocating motion of the rack 10 drives the gear 14 to rotate. The gear 14 is fixedly connected to the connecting shaft 15. One end of the connecting shaft 15 is fixedly connected to the ball valve 16. The rotation of the gear 14 causes the ball valve 16 to rotate. The flow rate is changed by changing the opening size of the ball valve 16. The flow detector 7 detects the flow rate. Real-time flow rate allows for easy flow adjustment. The liquid in reactor 2 enters another reactor 23 via connecting pipe 12 for continuous reaction. When the micro-conduit 6 in reactors 2 and 23 needs cleaning, pressing the pusher 5 on the positioning seat 4 causes the buckle 3 to rotate around the buckle shaft 18, compressing the spring 17 and causing the buckle 3 to leave the baffle 21 to open reactor 2, allowing the micro-conduit 6 to be cleaned. After cleaning, the micro-conduit 6 is placed back into reactors 2 and 23. Pressing the pusher 5 on the positioning seat 4 causes the buckle 3 to rotate around the buckle shaft 18, compressing the spring 17 and causing the buckle 3 to engage with the baffle 21 and seal the opening with the sealing ring 11, achieving the effect of disassembly for cleaning and fixed sealing.
