Description

Technical Field

[0001] This utility model relates to the field of soybean oil conveying pipeline technology, and in particular to an anti-crystallization and heat preservation device for soybean oil conveying pipelines. Background Technology

[0002] Soybean oil transportation refers to the safe and efficient transfer of soybean oil (hereinafter referred to as soybean oil) from one stage of production, storage, processing, or use to the next stage via pipelines, tanker trucks, or other means. During this process, especially under low ambient temperatures, saturated fatty acids in soybean oil may precipitate and form fat crystals, causing the oil to become cloudy and lose fluidity. In severe cases, this can cause blockages in pipelines or valves, affecting transportation efficiency and the normal operation of the system.

[0003] In traditional soybean oil transportation systems, anti-crystallization measures mainly rely on heating the outside of the pipeline with electric heating tape, supplemented by external insulation materials such as rock wool and glass wool. However, since the insulation materials are mostly fixed in a simple way, they are prone to displacement or falling off due to vibration, thermal expansion and contraction during long-term operation. This results in discontinuous insulation layers, reduced thermal resistance, and rapid heat loss from the pipeline. To compensate for the heat loss, the heating device needs to be repeatedly started, which not only aggravates energy consumption but also increases the equipment failure rate and maintenance workload.

[0004] Therefore, a crystallization-preventing and heat-insulating device is needed for soybean oil conveying pipelines. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, which often use simple fixing methods for insulation materials, making them prone to displacement or detachment due to vibration, thermal expansion and contraction during long-term operation, resulting in discontinuous insulation layers, reduced thermal resistance, and rapid heat loss from the pipeline, and requiring repeated starting of the heating device to compensate for heat loss, which not only exacerbates energy consumption but also increases equipment failure rate and maintenance workload, this utility model provides an anti-crystallization insulation device for soybean oil conveying pipelines.

[0006] The technical solution is as follows: A soybean oil conveying pipeline anti-crystallization and heat preservation device includes a support frame, a first conveying pipe, a connecting pipe, a heating pipe, a controller, and a second conveying pipe. The first conveying pipe is installed on the support frame. The right end of the first conveying pipe is connected to and communicates with the connecting pipe. The heating pipe is wound around the connecting pipe. The controller is installed on the connecting pipe and is electrically connected to the heating pipe. The right end of the connecting pipe is connected to and communicates with the second conveying pipe. The device also includes heat insulation cotton, a connecting rod, clamps, and springs. The first and second conveying pipes are wrapped with heat insulation cotton. Two clamps are installed outside the heat insulation cotton. The two clamps are rotatably connected to the connecting rod. A spring is sleeved on the connecting rod. The two ends of the spring are respectively connected to the two clamps.

[0007] Furthermore, it also includes a support frame, a filter plate, and an air pipe. The top of the first delivery pipe is provided with a support frame, the top of the support frame is snapped with a filter plate, and the air pipe is connected and communicated with the support frame.

[0008] Furthermore, it also includes a motor, a rotating rod, and a stirring blade. The support frame and the top of the second conveying pipe are both equipped with motors. The first and second conveying pipes are both rotatably equipped with rotating rods. The output shaft of the motor is connected to the rotating rods through a coupling. The lower end of the rotating rods is equipped with stirring blades.

[0009] Furthermore, it also includes a rubber sheet, which is installed on the clamp.

[0010] Furthermore, it also includes a corrugated pipe, with the other end of the vent pipe connected to a corrugated pipe.

[0011] Furthermore, it also includes a damping plate, which is installed inside the support frame and is in close contact with the filter plate.

[0012] Compared with the prior art, this utility model provides an anti-crystallization and heat preservation device for soybean oil conveying pipelines, which has the following beneficial effects: 1. The clamping plate always clamps the heat preservation cotton under the action of the spring, ensuring that it is tightly attached to the outer wall of the pipeline, effectively slowing down the heat loss inside the pipeline, maintaining the temperature of soybean oil, reducing the energy consumption of the heating tube, thereby achieving the best heat preservation effect. The synergistic effect of the heating tube's heating and temperature control and the heat preservation cotton's efficient heat insulation achieves the dual goals of energy saving and anti-crystallization.

[0013] 2. Inert gas is introduced into the first delivery pipe through the vent pipe. The inert gas creates a low-oxygen environment in the pipe, effectively isolating oxygen from contact with soybean oil, inhibiting fat oxidation and rancidity, thereby maintaining the quality of the oil and extending its shelf life.

[0014] 3. The motor's output shaft drives the rotating rod to rotate at high speed, causing the stirring blades to agitate the soybean oil flowing into the pipe. This not only breaks up any tiny crystal nuclei that may form, preventing them from agglomerating and growing, but also makes the temperature distribution more uniform, effectively preventing crystallization blockage and improving the anti-crystallization effect.

Detailed Implementation

[0022] 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.

[0023] Example 1: An anti-crystallization and heat preservation device for soybean oil conveying pipelines, such as... Figures 1-6 The device includes a support frame 1, a first conveying pipe 2, a connecting pipe 3, a heating pipe 4, a controller 5, and a second conveying pipe 6. The first conveying pipe 2 is mounted on the support frame 1. The right end of the first conveying pipe 2 is connected to and communicates with the connecting pipe 3. The heating pipe 4 is wound around the connecting pipe 3. The controller 5 is mounted on the connecting pipe 3. The controller 5 is a PLC controller and is electrically connected to the heating pipe 4. The right end of the connecting pipe 3 is connected to and communicates with the second conveying pipe 6. The device also includes insulation cotton 7, a connecting rod 8, clamping plates 9, and springs 10. The first conveying pipe 2 and the second conveying pipe 6 are wrapped with insulation cotton 7. Two clamping plates 9 are mounted on the outside of the insulation cotton 7. The two clamping plates 9 are rotatably connected to the connecting rod 8. Springs 10 are mounted on the connecting rod 8. The two ends of the springs 10 are connected to the two clamping plates 9 respectively. Rubber plates 11 are mounted on the clamping plates 9 to facilitate operation of the clamping plates 9 and improve hand comfort when maintaining or replacing the insulation cotton 7.

[0024] When this device is needed, soybean oil enters the device from the first conveying pipe 2 and flows through the connecting pipe 3. If the ambient temperature is low, there is a risk of crystallization. At this time, the heating pipe 4 is activated and heats up under the control of the controller 5, directly and precisely heating the soybean oil flowing through this section to ensure that its temperature is maintained above the crystallization point, thereby effectively preventing the formation of fat crystals. In addition, the outer sides of the first conveying pipe 2 and the second conveying pipe 6 are wrapped with heat insulation cotton 7. The clamping plate 9 is always clamped tightly to the heat insulation cotton 7 under the action of the spring 10, ensuring that it is in close contact with the outer wall of the pipe, effectively slowing down the heat loss in the pipe, maintaining the temperature of the soybean oil, reducing the energy consumption of the heating pipe 4, and thus achieving the best heat preservation effect. At the same time, the clamping structure allows the clamping plate 9 to rotate around the connecting rod 8, and can be easily opened and disassembled when maintaining or replacing the heat insulation cotton 7, which is convenient for daily inspection and maintenance. Through the synergistic effect of the heating and temperature control of the heating pipe 4 and the efficient heat insulation of the heat insulation cotton 7, the dual goals of energy saving and anti-crystallization are achieved.

[0025] Example 2: Based on Example 1, such as Figure 1 and Figure 5 It also includes a support frame 12, a filter plate 13, and a vent pipe 14. The support frame 12 is provided at the top of the first conveying pipe 2. The filter plate 13 is snapped onto the top of the support frame 12 to intercept impurities such as particulate matter and residue in the raw oil, preventing blockage of the pipeline or damage to the equipment. The vent pipe 14 is connected and communicated on the support frame 12. The other end of the vent pipe 14 is connected to a corrugated pipe 15, which facilitates connection to inert gas storage containers in different locations. A damping plate 16 is provided inside the support frame 12. The damping plate 16 is in close contact with the filter plate 13 to increase resistance and prevent the filter plate 13 from loosening.

[0026] To prevent soybean oil from oxidizing and deteriorating during transportation, inert gas can be introduced into the first conveying pipe 2 through the vent pipe 14 before or during transportation. The inert gas creates a low-oxygen environment in the pipe, effectively isolating oxygen from contact with soybean oil, inhibiting fat oxidation and rancidity, thereby maintaining the quality of the oil and extending its shelf life.

[0027] like Figure 1 and Figure 6 It also includes a motor 17, a rotating rod 18 and a stirring blade 19. The support frame 1 and the top of the second conveying pipe 6 are both equipped with motors 17. The first conveying pipe 2 and the second conveying pipe 6 are both rotatably equipped with rotating rods 18. The output shaft of the motor 17 is connected to the rotating rod 18 through a coupling. The lower end of the rotating rod 18 is equipped with a stirring blade 19.

[0028] During the soybean oil conveying process, the motor 17 is started, and the output shaft of the motor 17 drives the rotating rod 18 to rotate at high speed, so that the stirring blade 19 agitates the soybean oil flowing into the pipeline. This can break up any tiny crystal nuclei that may form, preventing them from agglomerating and growing; it can also make the temperature distribution more uniform, effectively preventing crystallization blockage and improving the anti-crystallization effect.

[0029] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
