Description

Technical Field

[0001] This utility model relates to a production synthesis equipment, and more particularly to an HFO-1234yf production synthesis equipment, belonging to the field of refrigerant processing technology. Background Technology

[0002] As global environmental governance continues to deepen, addressing ozone layer depletion and global warming has become an international consensus. Against this backdrop, traditional refrigerants that have ozone-depleting effects and significant greenhouse effect potential (GWP) are gradually being phased out of the mainstream application market.

[0003] As a core category of fourth-generation environmentally friendly refrigerants, HFO-1234yf (2,3,3,3 - tetrafluoropropylene) possesses excellent environmentally friendly characteristics: its ozone depletion potential (ODP) is 0, which has no destructive effect on the atmospheric ozone layer; at the same time, its greenhouse effect potential (GWP) is ≤1, its retention period in the atmosphere is short, and its contribution to global warming is extremely low, which is in line with the current global demand for low-carbon and environmentally friendly development.

[0004] In the synthesis and production of HFO-1234yf refrigerant, the static mixer is a key piece of equipment for achieving efficient material mixing. As an environmentally friendly refrigerant, the synthesis reaction of HFO-1234yf places stringent requirements on the uniformity and stability of material mixing, necessitating precise control of the mixing ratio and contact state of different reactants (such as hydrogen fluoride and other precursors). The static mixer, through its specific internal structure (such as the mixing unit of the SK type), eliminates the need for moving parts. Relying on the fluid flow itself and the action of the mixing elements, it ensures thorough mixing of all materials involved in the HFO-1234yf synthesis within the pipeline, providing favorable reaction conditions for subsequent catalytic reactions. This is of great significance for improving synthesis efficiency, ensuring product quality, and increasing yield.

[0005] Current technologies still have shortcomings:

[0006] Existing synthesis equipment struggles to quickly switch between different diameter delivery pipes and associated static mixing cores during the material mixing stage, based on production needs. Since pipe diameter directly impacts material flow rate and mixing efficiency (larger diameters result in faster flow rates and quicker mixing, while smaller diameters lead to slower flow rates and slower mixing), existing equipment cannot rapidly respond to mixing demands under varying production conditions. This hinders the accuracy and stability of material mixing during the synthesis process, limiting further improvements in the synthesis efficiency and product quality of HFO-1234yf.

[0007] To address these issues, an HFO-1234yf production and synthesis equipment was designed. Utility Model Content

[0008] The main objective of this invention is to provide an HFO-1234yf production and synthesis device to solve the problems mentioned in the background art.

[0009] The objective of this utility model can be achieved by adopting the following technical solution:

[0010] A synthesis device for producing HFO-1234yf includes a rotating drum. Pipe 1 and Pipe 2 are installed inside the rotating drum, and mixing blades are installed inside both pipes. A collar is fixed at both ends of the rotating drum. A rotating block rotates inside the collar, and a port is opened on one side of each rotating block. A rotating ring is fixed to the outer side of each rotating block, and a side ring is fixed to the side of each rotating block away from its center. A connecting pipe is installed on each side ring, offset from the center, and the connecting pipe communicates with the port. A limit assembly is provided between the collar and the rotating ring. C-shaped plates are evenly installed on the outer side of the collar, and grooves are opened on the top of each C-shaped plate. The same number of fixing plates as the C-shaped plates are evenly installed on the outer side of the rotating ring, and a slot is opened in the middle of each fixing plate, with a screw hinged inside the slot.

[0011] Preferably, the limiting component includes a magnetic block one and a magnetic block two, with magnetic block one evenly installed on the outer side of the collar and magnetic block two evenly installed on the outer side of the rotating ring.

[0012] Preferably, pipe one and pipe two have different diameters, and the diameter of pipe one is larger than the diameter of pipe two.

[0013] Preferably, a limiting ring is fixed on the inner side of the collar, and an annular groove adapted to the limiting ring is opened on the outer side of the rotating block. The limiting ring is embedded in the annular groove to realize the rotational connection between the collar and the rotating block.

[0014] Preferably, the orifice diameter is adapted to the inner diameter of pipe one and pipe two, and the axis of the orifice is collinear with the axis of pipe one and pipe two.

[0015] Preferably, the groove is provided with an anti-slip pad, and the anti-slip pad is uniformly provided with anti-slip texture.

[0016] Preferably, the two ends of the rotating drum are equipped with scale lines, which correspond to the working positions of pipe one and pipe two.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model utilizes a combination of a rotating drum, pipe one, pipe two, collar, rotating block, port, rotating ring, side ring, connecting pipe, groove, U-shaped plate, fixing plate, slot, screw, and mixing blades. By rotating the drum as needed, pipes of suitable diameters can be quickly switched without complex disassembly, significantly improving the convenience and efficiency of pipe diameter adjustment. Different pipe diameters are precisely matched to different flow rates and mixing efficiency requirements, adapting to various mixing conditions in the synthesis of HFO-1234yf, helping to improve material mixing quality, providing stable assurance for subsequent reaction efficiency and product yield, optimizing the overall equipment operation process, and reducing maintenance costs.

[0019] 2. This utility model uses the cooperation of magnetic block one and magnetic block two. When the rotating drum is rotated, the collar rotates along the rotating ring. The C-shaped plate and the fixed plate, as well as magnetic block one and magnetic block two, are aligned and attracted, which can quickly perform preliminary positioning, simplify subsequent limit operation, improve the efficiency of equipment adjustment and assembly, and ensure smooth pipeline switching and mixing process.

[0032] Example 1

[0033] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment proposes an HFO-1234yf production synthesis device, including a rotating drum 1. Pipe 1 2 and pipe 2 3 are respectively installed inside the rotating drum 1. Mixing blades 16 are installed inside both pipe 1 2 and pipe 2 3. The mixing blades 16 adopt an SK-type static mixing unit structure, specifically, alternating left-handed and right-handed spiral plates twisted by 180°. Both ends of the rotating drum 1 are fixed with collars 4. Rotating blocks 5 rotate inside the collars 4. Each rotating block 5 has an opening 6 on one side. A rotating ring 7 is fixed on one side, and a side ring 9 is fixed on the side of the rotating block 5 that is far away from it. A connecting pipe 10 is provided on each side ring 9 that is off-center from the middle position, and the connecting pipe 10 is connected to the through port 6. A limit component 8 is provided between the collar 4 and the rotating ring 7. A C-shaped plate 12 is evenly installed on the outer side of the collar 4. A groove 11 is opened on the top of each C-shaped plate 12. The same number of fixing plates 13 as the C-shaped plates 12 are evenly arranged on the outer side of the rotating ring 7. A slot 14 is opened in the middle position of the fixing plate 13. A screw 15 is hinged inside the slot 14.

[0034] After the equipment is assembled with the conveying pipeline through the two end connectors 10, a rotational force is applied to the rotating drum 1. The rotating drum 1, along with the linkage collar 4 and the C-shaped plate 12, rotates synchronously. The internal pipes 2 and 3 rotate in coordination with the rotating drum 1, so that the pipe 2 or 3 with the appropriate pipe diameter rotates to the upper position, aligning the pipes 2 and 3 vertically, and connecting the pipes 2 and 3 to the port 6. At the same time, the C-shaped plate 12 on the outside of the collar 4 aligns with the corresponding fixing plate 13 on the outside of the rotating ring 7, and the screw 15 is flipped into the groove 11. After the screw 15 is inserted into the groove 11, the matching nut is used to lock the C-shaped plate 12 and the fixing plate 13, realizing the bidirectional limiting and fixing of the collar 4 and the rotating ring 7, and the rotating drum 1 and the side ring 9. After the mechanical structure is locked, the material conveying channel is opened. The mixed materials are conveyed to the inlet 6 through the pipe 10 and introduced by the pipe 2 or pipe 3 aligned with the inlet 6. The mixing blades 16 inside the pipe are used to carry out the mixing operation, accurately matching the flow rate and mixing efficiency requirements of different pipe diameters.

[0035] Example 2

[0036] The solution in Example 1 will be further described below with reference to its specific working method.

[0037] like Figure 1 As shown, in a preferred embodiment, based on the above method, the limiting component 8 further includes a first magnetic block 801 and a second magnetic block 802. The first magnetic block 801 is evenly installed on the outer side of the collar 4, and the second magnetic block 802 is evenly installed on the outer side of the rotating ring 7.

[0038] When rotating the rotating cylinder 1, the rotating cylinder 1 simultaneously drives the collar 4 to rotate along one side of the rotating ring 7 until the C-shaped plate 12 on the rotating collar 4 and the fixed plate 13 on the outer side of the rotating ring 7 are aligned. At the same time, the magnetic block 801 on the outer side of the collar 4 and the magnetic block 802 on the outer side of the rotating ring 7 are aligned and attract each other, which plays a preliminary positioning role and brings convenience to the subsequent limiting work.

[0039] like Figure 4 As shown, in a preferred embodiment, based on the above method, the pipe diameters of pipe 2 and pipe 3 are different, and the pipe diameter of pipe 2 is larger than that of pipe 3.

[0040] By setting up pipes of different diameters, the appropriate pipes can be flexibly switched according to the material characteristics and mixing requirements at different stages of the HFO-1234yf synthesis process, so as to achieve precise control of material flow rate and mixing efficiency and improve the adaptability of the equipment to diverse production conditions.

[0041] like Figure 4As shown, in a preferred embodiment, based on the above method, a limiting ring is fixed on the inner side of the collar 4, and an annular groove adapted to the limiting ring is opened on the outer side of the rotating block 5. The limiting ring is embedded in the annular groove to realize the rotational connection between the collar 4 and the rotating block 5. Two U-shaped polytetrafluoroethylene (PTFE) sealing rings are provided on the contact surface of the annular groove between the collar 4 and the rotating block 5.

[0042] The combination of the annular groove and the limiting ring can ensure the smooth relative rotation of the collar 4 and the rotating block 5, and also radially limit their relative positions to avoid deviation or shaking during rotation, thus ensuring the alignment accuracy when switching pipelines.

[0043] like Figure 4 As shown, in a preferred embodiment, based on the above method, the diameter of the orifice 6 is adapted to the inner diameter of pipe 1 2 and pipe 2 3, and the axis of the orifice 6 is collinear with the axis of pipe 1 2 and pipe 2 3.

[0044] When materials are transferred between inlet 6 and pipe 2 or pipe 3, turbulence and stagnation caused by mismatched diameters or axial offset are avoided, material conveying resistance is reduced, local pressure loss is decreased, and the stability of the mixing process is ensured.

[0045] like Figure 1 As shown, in a preferred embodiment, based on the above method, the groove 11 is further provided with an anti-slip pad, and the anti-slip pad is uniformly provided with anti-slip texture.

[0046] The anti-slip pad and anti-slip texture can increase the friction between the screw 15 and the inner wall of the groove 11. After the screw 15 is inserted and locked, the stability of the connection is further improved, preventing the screw 15 from loosening due to vibration during equipment operation and enhancing the reliability of the structure locking.

[0047] like Figure 1 As shown, in a preferred embodiment, based on the above method, the two ends of the rotating drum 1 are further provided with scale lines, which correspond to the working positions of pipe 1 2 and pipe 2 3.

[0048] The scale lines can intuitively indicate the current position of pipe 1 (2) and pipe 2 (3), making it easy for operators to quickly judge and accurately rotate to the target position, shortening the operation time of pipe switching, improving adjustment efficiency, and reducing the risk of operational errors caused by alignment deviation.

[0049] Example 3

[0050] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0051] After the equipment is assembled with the conveying pipeline via the two-end connecting pipes 10, a rotational force is applied to the rotating drum 1. The rotating drum 1 drives the collar 4 to rotate synchronously along the rotating ring 7, and the internal pipes 2 and 3 rotate in coordination with the rotating drum 1. During the rotation, the U-shaped plate 12 on the outer side of the collar 4 gradually aligns with the fixed plate 13 on the outer side of the rotating ring 7. At the same time, the magnetic block 801 on the outer side of the collar 4 and the magnetic block 802 on the outer side of the rotating ring 7 are synchronously aligned and attract each other, achieving preliminary positioning and facilitating subsequent limit operations.

[0052] Continue rotating until the pipe 1 (2) or pipe 2 (3) of the appropriate diameter is rotated to the upper position, ensuring that the target pipe, pipe 1 (2) or pipe 2 (3) can connect with the port 6. At this time, flip the screw 15 into the groove 11 and insert it, and use the matching nut to lock the U-shaped plate 12 and the fixing plate 13, so as to achieve bidirectional limiting and fixing of the collar 4 and the rotating ring 7, and the rotating cylinder 1 and the side ring 9.

[0053] After the mechanical structure is locked, the material conveying channel is opened. The mixed materials are conveyed to the inlet 6 through the pipe 10 and introduced by the pipe 2 or pipe 3 aligned with the inlet 6. The mixing operation is carried out with the help of the mixing blades 16 in the pipe, which accurately matches the flow rate and mixing efficiency requirements corresponding to different pipe diameters.

[0054] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
