Description

Technical Field

[0001] This utility model relates to the field of oil and gas recovery composite membrane production technology, and in particular to a mixing device for an oil and gas recovery composite membrane. Background Technology

[0002] Oil and gas recovery composite membranes, as devices for separating oil and gas, are commonly used in gas stations. Chinese Patent Application No. 2022107464143, published on September 2, 2022, discloses an oil and gas recovery composite membrane and its preparation method. The preparation method includes mixing an aqueous dispersion of a silane coupling agent and nano-SiO2 with a fluororesin solution to obtain a composite membrane solution; then repeatedly immersing a PVDF-HFP base membrane in the composite membrane solution, followed by drying to obtain the final product. The oil and gas recovery composite membrane prepared by this invention has a simple preparation process, a long membrane lifespan, and is less affected by temperature. Its separation performance remains relatively stable even when the ambient temperature varies from 0 to 50 degrees Celsius, and the concentration of exhaust oil and gas can be kept below 10 g / m³. When preparing oil and gas recovery composite membranes, maintaining a temperature of around 40 degrees Celsius can achieve high mixing efficiency. However, due to ambient temperature and chemical reactions during the preparation process, it is difficult to maintain the temperature inside the mixing tank at around 40 degrees Celsius, resulting in excessively high or low temperatures that affect mixing efficiency. In existing technologies, temperature control devices are mostly located on the outer wall of the mixing tank. By cooling the outer wall of the mixing tank, the temperature is transferred to the inside of the mixing tank, thereby achieving temperature control of the materials inside the mixing tank. However, this method has low temperature control efficiency, which affects the mixing efficiency. Therefore, a mixing device that solves the above problems is needed. Utility Model Content

[0024] This application discloses a mixing device for an oil and gas recovery composite membrane. (Refer to...) Figure 1 , Figure 2, Figure 4 The system includes a mixing tank 1, used to place the raw materials for producing the oil and gas recovery composite membrane liquid into the mixing tank 1 for thorough mixing and stirring, thereby obtaining the oil and gas recovery composite membrane liquid. A support assembly is connected to the bottom of the mixing tank 1, providing support and constraint to ensure the mixing tank 1 stands stably on the ground. The support assembly includes several support legs 2 and reinforcing rods 3. One end of each support leg 2 is welded or detachably fixed to the bottom of the mixing tank 1 with bolts, thus connecting the support legs 2 to the mixing tank 1 and providing support. Reinforcing rods 3 are welded or detachably fixed to adjacent support legs 2, connecting the reinforcing rods 3 to the support legs 2, thereby increasing the stability of the support legs 2 and providing stable support for the mixing tank 1. A sealing cover 5 is connected to the opening of the mixing tank 1. Specifically, a fixing ring 4 is welded to the outer surface of the opening of the mixing tank 1, connecting the fixing ring 4 to the opening of the mixing tank 1 to form a whole. The sealing cap 5 is detachably fixed to the fixing ring 4 by bolts. This connection seals the opening of the mixing tank 1, preventing external debris from entering. The detachable connection also allows for easy access to the mixing tank 1's opening, facilitating maintenance of its internal mechanical structure. A discharge pipe 24 connects to the bottom of the mixing tank 1, allowing the oil-gas recovery composite membrane liquid to be discharged. The sealing cap 5 has a feeding port 22, and a feeding channel 23 is welded to or detachably fixed to the sealing cap 5 at the feeding port 22, allowing the oil-gas recovery composite membrane liquid raw material to be fed into the mixing tank 1 through the feeding channel 23 and the feeding port 22.

[0025] Referring to Figures 2 and 4, a pair of support blocks 6 are detachably and fixedly connected to the sealing cover 5 by bolts, forming an integral unit with the sealing cover 5. A drive motor 7 is detachably and fixedly connected to the support blocks 6 by bolts, connecting the drive motor 7 to the support blocks 6, thereby connecting the drive motor 7 to the sealing cover 5. A rotating shaft 8 is detachably and fixedly connected to the output shaft of the drive motor 7 via a coupling, connecting the rotating shaft 8 to the output shaft of the drive motor 7. When the drive motor 7 is energized, its output shaft drives the rotating shaft 8 to rotate. The rotating shaft 8 extends through the sealing cover 5 into the mixing tank 1. A mixing and stirring rod assembly is sealed and welded to the rotating shaft 8 inside the mixing tank 1, connecting the mixing and stirring rod assembly to the rotating shaft 8. When the rotating shaft 8 rotates, it drives the mixing and stirring rod assembly to rotate, thoroughly mixing and stirring the oil-gas recovery composite membrane liquid raw material in the mixing tank 1.

[0026] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6The mixing and stirring rod assembly is internally connected to the rotating shaft 8, allowing hot or cold water to flow within both the rotating shaft 8 and the mixing and stirring rod assembly. Specifically, the rotating shaft 8 has a central bore, within which several partition plates 801 are integrally formed. These partition plates 801 divide the central bore into several independent infusion channels 802, allowing cold or hot water to be delivered through these channels. The mixing and stirring rod assembly is connected to the infusion channels 802, enabling the hot or cold water within the channels 802 to flow within the mixing and stirring rod assembly. This allows for both mixing and temperature control of the raw materials. The mixing rod assembly consists of several sets of mixing rod meshes, including an upper horizontal rod 901, a middle horizontal rod 904, a lower horizontal rod 903, and a vertical rod 902. One end of the upper horizontal rod 901, the middle horizontal rod 904, and the lower horizontal rod 903 is sealed and welded to the rotating shaft 8, and the other end is sealed and welded to the vertical rod 902. Both ends of the upper horizontal rod 901, the middle horizontal rod 904, and the lower horizontal rod 903 are connected to the rotating shaft 8 and the vertical rod 902, so that the entire mixing rod mesh is connected. At the same time, the mixing rod mesh is connected to the liquid delivery channel 802 inside the rotating shaft 8. Specifically, the upper horizontal bar 901, middle horizontal bar 904, lower horizontal bar 903, and vertical bar 902 are provided with interconnected inlet holes 905 and outlet holes 906. The liquid delivery channel 802 is provided with a first connecting hole 803 and a second connecting hole 804. The inlet holes 905 and outlet holes 906 in each set of stirring rods are respectively connected to the first connecting holes 803 and the second connecting holes 804 in two adjacent liquid delivery channels 802. This allows one of the liquid delivery channels 802 to deliver hot or cold water into the stirring rods through the first connecting hole 803 and the inlet hole 905. After passing through the stirring rods, the hot or cold water is delivered to the adjacent liquid delivery channel 802 through the outlet hole 906 and the second connecting hole 804, and then discharged from the rotating shaft 8. This achieves continuous delivery of hot or cold water into the mixing stirring rod group, thereby controlling the temperature inside the mixing tank 1.

[0027] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6A connecting block 10 is detachably fixed to the sealing cover 5 by bolts, so that the connecting block 10 and the sealing cover 5 are connected together to form a whole. The connecting block 10 is sleeved on the outside of the rotating shaft 8, so that the rotating shaft 8 can rotate relative to the connecting block 10. The connecting block 10 is provided with a set of infusion pipes 17 that communicate with the rotating shaft 8, so that hot water or cold water is supplied to the rotating shaft 8 through the set of infusion pipes 17, and hot water or cold water passing through the mixing and stirring rod assembly is discharged through the set of infusion pipes 17, so as to continuously supply hot water or cold water to the rotating shaft 8 and the mixing and stirring rod assembly, thereby controlling the temperature inside the mixing tank 1. The infusion tubing 17 group includes several sealing rings and several infusion tubing 17. Several first sealing ring grooves 12 are formed on the outer surface of the rotating shaft 8, and several corresponding second sealing ring grooves 11 are formed on the connecting block 10. The first sealing rings 13 are engaged in the first sealing ring grooves 12 and the second sealing ring grooves 11, so that the first sealing rings 13 are engaged and limited by the first sealing ring grooves 12 and the second sealing ring grooves 11, preventing the first sealing rings 13 from detaching from the rotating shaft 8 and the connecting block 10. At the same time, the first sealing rings 13 seal the gap between the rotating shaft 8 and the connecting block 10, ensuring that the rotating shaft 8 can rotate relative to the connecting block 10, and preventing hot or cold water from leaking out from the gap between the rotating shaft 8 and the connecting block 10. The sealing cover 5 has several third sealing ring grooves 19, and the bottom of the connecting block 10 has several corresponding fourth sealing ring grooves 20. A second sealing ring 21 is engaged in the third sealing ring grooves 19 and the fourth sealing ring grooves 20, so that the second sealing ring 21 is engaged and limited by the third sealing ring grooves 19 and the fourth sealing ring grooves 20, preventing the second sealing ring 21 from detaching from the sealing cover 5 and the connecting block 10. At the same time, the second sealing ring 21 is used to seal the gap between the sealing cover 5 and the connecting block 10, preventing hot or cold water from leaking out from the gap between the sealing cover 5 and the connecting block 10.A first annular groove 15 is formed on the outer surface of the rotating shaft 8 between two adjacent first sealing ring grooves 12, and a corresponding second annular groove 14 is formed on the connecting block 10. Each first annular groove 15 has an infusion hole 18 that connects to the inside of the rotating shaft 8, and each infusion hole 18 is connected to one of the infusion channels 802. The connecting block 10 has several through holes 16 that connect to the second annular grooves 14. One end of the infusion tube 17 is connected to the through holes 16 from top to bottom. The infusion tube 17 is connected to a hot water tank and a cold water tank through a water pump, so that the infusion tube 17 delivers fluid into the through holes 16. Hot or cold water enters the first annular groove 15 and the second annular groove 14, and is then transported to the infusion channel 802 through the infusion hole 18. At the same time, water in the adjacent infusion channel 802 can be transported to the adjacent first annular groove 15 and the second annular groove 14 through the infusion hole 18, and then discharged through the through hole 16 and the infusion pipe 17. This enables the continuous supply of hot or cold water to the rotating shaft 8 and the mixing rod assembly, thereby achieving rapid adjustment of the temperature in the mixing tank 1. Furthermore, the temperature adjustment in the mixing tank 1 does not affect the mixing and stirring of the raw materials in the mixing tank 1 by the mixing rod assembly.

[0028] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components, and the structural settings, working methods or control methods involved are all conventional settings, working methods or control methods in the art unless otherwise specified.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
