Description

Technical Field

[0001] This utility model relates to the field of bio-jet fuel technology, specifically to a selective collection device for isomeric fractions of bio-jet fuel. Background Technology

[0002] The fractionation process involves separating kerosene components that meet aviation standards from bio-jet fuel through fractionation technology. Combined with isomerization, this process lowers the fuel's pour point, improves low-temperature performance, and ensures flight safety. At the same time, it utilizes renewable raw materials to reduce carbon emissions and promotes the greening of aviation fuel. In the rectification and separation stage, the fractionation equipment utilizes the boiling point differences of different hydrocarbon components and selectively separates the target fraction products by controlling parameters such as temperature and pressure. The fraction products are then discharged into specific containers for collection by personnel.

[0003] The existing distillation discharge components are too far from the vessel, causing the distillate to splash out or mix with other impurities during its fall, resulting in waste of distillate or affecting the purity of the distillate. Relying on manual or semi-automatic equipment, it is impossible to achieve continuous and efficient distillate collection. Therefore, a selective collection device for isomerized distillates of bio-jet fuel is proposed. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a selective collection device for isomer fractions of bio-jet fuel.

[0005] The technical solution adopted by this utility model to solve its technical problem is a selective collection device for isomer fractions of bio-jet fuel, including a housing, a rotating component and a pipe rack. The bottom of the rotating component is located inside one end of the housing, and the end of the pipe rack away from the rotating component is connected to the housing.

[0006] The rotating assembly includes a mounting base plate, a petal-shaped rotating chassis, a central support plate, and a top support plate. The mounting base plate is located inside the equipment housing at the waist and is fixed to the equipment housing with bolts. The center of the petal-shaped rotating chassis is rotatably connected to the top of the mounting base plate via a bearing. The central support plate and the top support plate are sequentially located on the top of the petal-shaped rotating chassis, and the top of the petal-shaped rotating chassis is connected to the central support plate and the top support plate via a support column. The support column is glued and fixed to the petal-shaped rotating chassis, the central support plate, and the top support plate.

[0007] By adopting the above technical solution, a device is provided for the selective collection of distilled and separated products in the selective collection stage of bio-jet fuel isomers, consisting of a housing, rotating components, and a pipe rack.

[0008] Specifically, each petal of the petal-shaped rotating base has a slot for supporting the test tube. The bottom of the slot has a through hole, and the diameter of the through hole is smaller than the diameter of the top opening of the slot. The middle support plate and the top support plate have insertion holes at equal intervals corresponding to the slots.

[0009] By adopting the above technical solution, the tube body is limited by the insertion hole, and the bottom of the tube is supported by the bracket.

[0010] Specifically, an eccentric disk is rotatably mounted on one end of the mounting base plate via a bearing. A lever is mounted on the eccentric shaft of the eccentric disk that meshes with the outer petals of the petal-shaped rotating base. When the eccentric disk completes one revolution, the lever engages and drives the petal-shaped rotating base to rotate in a step-by-step manner along the axis, with a single indexing interval.

[0011] Specifically, a stepper motor is installed at the bottom of the mounting base plate and on the vertical line of the eccentric disk, and the output end of the stepper motor is fixedly connected to the center of the eccentric disk by a key pin.

[0012] An electric push rod is mounted on the mounting base plate and located on the side of the stepper motor. A pusher for pushing the test tube is mounted on the output end of the electric push rod. The diameter of the pusher is smaller than the diameter of the through hole at the bottom of the tray.

[0013] By adopting the above technical solution, and through the setting of stepper motor and eccentric disk, after the stepper motor drives the eccentric disk to rotate once, the petal-shaped rotating base can rotate in a step-by-step manner along the axial direction, allowing the test tubes to pass under the tube rack one by one. When it is necessary to collect the distillate product from the test tubes under the tube rack, the electric push rod pushes the push seat upward, so that the push seat passes through the through hole of the groove under the test tube, and pushes the test tube upward, so that the tube opening is closer to the discharge nozzle of the tube rack. This allows the distillate product to fall more accurately into the test tube, which can effectively avoid the problem of distillate product splashing out or being mixed with other impurities due to being too far from the container during the fall, resulting in waste of distillate product or affecting the purity of the distillate.

[0014] Specifically, a discharge nozzle is provided at the bottom of one end of the pipe laying frame, the feed line of the discharge nozzle is laid inside the pipe laying frame, and an inspection port is provided at the top of the pipe laying frame. An inspection cover is provided on the top of the inspection port, and magnets are embedded at the closing points of the inspection cover and the inspection port. The inspection cover and the inspection port are connected by magnetic attraction.

[0015] The beneficial effects of this utility model are as follows: The assembly, consisting of a housing, a rotating component, and a tube rack, provides a continuous collection device for the selective collection of distillation-separated products from the isomerization of bio-jet kerosene. Through a step-by-step rotation, test tubes used for collecting distillation products sequentially pass below the discharge end of the tube rack. Simultaneously, the device actively lifts the test tubes being collected, bringing the tube openings closer to the discharge end of the distillation products. This reduces the likelihood of external influences on the distillation products as they fall into the test tubes, improving the reliability of distillation product collection. It also reduces the inertial impact force generated by the falling material, minimizing excessive splashing due to the high falling height. This results in better overall stability of distillation product collection. Furthermore, it addresses the problem of existing methods where the distance between the distillation discharge component and the vessel is too large, causing the distillation products to splash out or mix with other impurities during the fall, leading to product waste or affecting distillation purity. Finally, it solves the problem that existing collection methods rely on manual or semi-automatic equipment, failing to achieve continuous and efficient distillation collection.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-5As shown, the selective collection device for isomer fractions of bio-jet fuel according to this utility model includes a housing 1, a rotating component 2 and a pipe rack 3. The bottom of the rotating component 2 is disposed inside one end of the housing 1, and the end of the pipe rack 3 away from the rotating component 2 is connected to the housing 1.

[0025] The rotating assembly 2 includes a mounting base plate 21, a petal-shaped rotating chassis 22, a central support plate 24, and a top support plate 25. The mounting base plate 21 is located inside the waist of the equipment housing 1 and is fixed to the equipment housing 1 by bolts. The center of the petal-shaped rotating chassis 22 is rotatably connected to the top of the mounting base plate 21 through a bearing. The central support plate 24 and the top support plate 25 are sequentially arranged on the top of the petal-shaped rotating chassis 22, and the top of the petal-shaped rotating chassis 22 is connected to the central support plate 24 and the top support plate 25 by a support column 27. The support column 27 is glued and fixed to the petal-shaped rotating chassis 22, the central support plate 24, and the top support plate 25.

[0026] The present invention also includes that each group of petals of the petal-shaped rotating base 22 is provided with a slot 23 for supporting the test tube, and the bottom of the slot 23 is provided with a through hole, the diameter of which is smaller than the diameter of the top opening of the slot 23. The middle support plate 24 and the top support plate 25 are provided with insertion holes 26 corresponding to the slot 23 at equal intervals.

[0027] When in use, the tube body is limited by the insertion hole 26, and the bottom of the tube is supported by the bracket 23.

[0028] This utility model also includes an eccentric disk 28 rotatably mounted on one end of the top of the mounting base plate 21 via a bearing. A lever 29 is mounted on the eccentric shaft of the eccentric disk 28, which meshes with the outer petals of the petal-shaped rotating base 22. When the eccentric disk 28 completes one rotation, the lever 29 engages and drives the petal-shaped rotating base 22 to generate a step rotation with an indexing interval along the axis.

[0029] The present invention also includes a stepper motor 210 installed at the bottom of the mounting base plate 21 and on the vertical line of the eccentric disk 28, wherein the output end of the stepper motor 210 is fixedly connected to the center of the eccentric disk 28 by a key pin.

[0030] An electric push rod 211 is installed on the mounting base 21 and on one side of the stepper motor 210. A push seat 212 for pushing the test tube is installed on the output end of the electric push rod 211. The diameter of the push seat 212 is smaller than the diameter of the through hole at the bottom of the support groove 23.

[0031] In use, based on the stepper motor 210 and the eccentric disk 28, after the stepper motor 210 drives the eccentric disk 28 to rotate one revolution, the petal-shaped rotating base 22 can rotate in an axial step by a division interval, so that the test tubes can pass under the tube rack 3 one by one. When it is necessary to collect the distillate product, the test tube under the tube rack 3 is pushed by the electric push rod 211 to push the push seat 212. After the push seat 212 passes through the through hole of the groove 23 under the test tube, it pushes the test tube upward, so that the tube opening is closer to the discharge nozzle 31 of the tube rack 3. This allows the distillate product to fall more accurately into the test tube, which can effectively avoid the problem of distillate product splashing out or being mixed with other impurities due to being too far away from the container during the fall, causing waste of distillate product or affecting the purity of the distillate.

[0032] This utility model also includes a discharge nozzle 31 at one bottom of the tube rack 3, the feed line of the discharge nozzle 31 is laid inside the tube rack 3, and an inspection port 32 is opened at the top of the tube rack 3. An inspection cover 33 is provided on the top of the inspection port 32. Magnets are embedded at the closing points of the inspection cover 33 and the inspection port 32. The inspection cover 33 and the inspection port 32 are magnetically connected by magnets.

[0033] In use, the feed pipe of the discharge nozzle 31 is connected to the discharge end of the distillate product of the bio-jet fuel isomerization distillation equipment. Multiple test tubes are sequentially inserted into the slots 23 of the petal-shaped rotating base 22 through the insertion holes 26 on the middle support plate 24 and the top support plate 25. The tube body is limited by the insertion holes 26 on the middle support plate 24 and the top support plate 25 to ensure the stability of the test tube during rotation. The eccentric disk 28 is driven to rotate by the stepper motor 210. After the eccentric disk 28 rotates one revolution, the petal-shaped rotating base 22 is driven to rotate in a stepping interval along the axis by the lever 29. The next test tube is moved to the bottom of the discharge nozzle 31 of the tube rack 3. When the test tube moves to the bottom of the discharge nozzle 31, the electric push rod 211 is activated. The output end of the electric push rod 211 pushes the push seat 212 to rise. The push seat 212 passes through the through hole at the bottom of the tray 23 and lifts the test tube to a position close to the discharge nozzle 31. The discharge end of the distillation equipment begins to discharge. The distillate is discharged from the discharge nozzle 31 through the feed line in the tube rack 3 and falls into the lifted test tube. After the distillate product in the test tube reaches the predetermined amount, the distillation equipment stops discharging and lowers the push seat 212 through the electric push rod 211, and the test tube returns to the tray 23.

[0034] Furthermore, the control circuits of the stepper motor 210 and the electric push rod 211 are connected to the control host or PLC in the distillation operation site to uniformly control and allocate the working status of the stepper motor 210 and the electric push rod 211 based on the working status of the distillation equipment.

[0035] Furthermore, the inspection cover 33 on the top of the tube rack 3 is opened periodically, and the feed pipeline inside the tube rack 3 is cleaned and maintained through the inspection port 32, and the various parts of the rotating assembly 2 are checked for wear or damage. If necessary, they are replaced or repaired in a timely manner.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
