Description

Technical Field

[0001] This utility model relates to the technical field of shortening production systems, specifically to a pipeline short-connection structure for pressure reduction in a shortening production system. Background Technology

[0002] A shortening production system is an industrialized process and equipment system specifically designed to manufacture oil products with specific processing properties. Its core objective is to modify raw oils through physical or chemical means, combined with temperature control, machining, and other processes, to ultimately create shortening products that meet the needs of the food industry.

[0003] Currently, the connecting pipes of the quench kneading machine in the shortening production system are long and have many bends, such as Figure 1 As shown, the existing shortening production system requires a quench mixer 1, a kneading mixer 2, a small kneading mixer 3, and a transfer plate 4. Each transfer needs to be achieved through the transfer plate 4, which is located more than 10 meters away. This results in the original pipeline 5 being too long and having too many bends, which in turn leads to high resistance when the frozen shortening passes through the pipeline. As the production time increases, the amount of oil stuck to the pipeline wall increases, and the resistance gradually increases. The system pressure also increases. After multiple batches of production, the system must be shut down to alleviate the high pressure problem, which affects the production efficiency. For example, after 10 batches of shortening CNO35 and its products with the same formula are produced continuously, the pressure continues to rise to more than 95 bar, and the ammonia compressor needs to be stopped to melt the oil before restarting production.

[0004] In view of this, there is an urgent need for a pipeline short-circuit structure for reducing pressure in a shortening production system to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a pipeline short-connection structure for reducing pressure in a shortening production system.

[0006] The technical solution of this utility model is as follows:

[0007] A pipeline shorting structure for pressure reduction in a shortening production system includes:

[0008] The production system includes a quench mixer, a kneading mixer, and a small kneading mixer. Ports A1, A2, A3, and A4 of the quench mixer are connected sequentially through several short connecting pipes. Port A4 of the quench mixer is connected to port B1 of the kneading mixer through several short connecting pipes. Ports B1, B2, B3, and B4 of the quench mixer are connected sequentially through several short connecting pipes. Port B4 of the kneading mixer is connected to the small kneading mixer through several short connecting pipes.

[0009] The short pipes are connected end to end in sequence and fixedly connected by a connector device, which is unlocked by an unlocking device.

[0010] Furthermore, one end of the short connector is provided with a plug connector, and the other end is provided with a plug hole. The outer diameter of the plug connector is smaller than the outer diameter of the short connector, and the inner diameter of the plug hole is equal to the outer diameter of the plug connector. The plug connector and the plug hole cooperate to connect the short connectors end to end in sequence.

[0011] Furthermore, one end of the short pipe is provided with a first external thread and the other end is provided with a second external thread. The connector device includes a first connector and a second connector. The first connector is provided with a first internal thread in the middle and the second connector is provided with a second internal thread. The first internal thread is connected to the first external thread and the second internal thread is connected to the second external thread, so that the first connector and the second connector are respectively fitted onto both ends of the short pipe.

[0012] Furthermore, one end of the first connector is provided with several buckles, which are arranged in a central array. One end of the second connector is provided with several snap-fit ​​cavities, the number and spacing angle of which are the same as the buckles. The buckles of the other short pipe connected to it are inserted into the snap-fit ​​cavities.

[0013] Furthermore, a locking pin is provided inside the locking cavity. The locking pin is wedge-shaped, and a locking pin connecting rod is provided on the side of the locking pin. A spring is sleeved on the locking pin connecting rod. When the buckle is inserted into the locking cavity, the buckle pushes the locking pin in the direction of spring compression. The length of the locking pin is less than the length of the buckle. When the buckle is fully inserted into the locking cavity, the spring returns to its original state, so that the locking pin moves inward and locks the buckle.

[0014] Furthermore, the second connector is provided with a connecting rod through hole, and the other end of the locking pin connecting rod passes through the connecting rod through hole and is connected to the unlocking device.

[0015] Furthermore, the unlocking device includes an unlocking pressure plate, a rotating shaft, and a support frame. The support frame is fixedly mounted on the outer surface of the second connector and has a second rotating shaft through hole. One end of the unlocking pressure plate is fixedly connected to the locking pin connecting rod, and the side of the unlocking pressure plate has a first rotating shaft through hole. The support frame is mounted on both sides of the unlocking pressure plate. The rotating shaft passes through the first rotating shaft through hole and the second rotating shaft through hole. The unlocking pressure plate rotates around the rotating shaft. When the free end of the unlocking pressure plate is pressed, the end of the unlocking pressure plate connected to the locking pin connecting rod moves in the opposite direction, thereby driving the locking pin to move outward towards the short tube.

[0016] Furthermore, the free end of the unlocking pressure plate is tilted outwards towards the short tube.

[0017] The beneficial effects achieved by this utility model are as follows:

[0018] 1. This utility model shortens the pipeline length by using a short connecting pipe, reduces the number of right-angle and obtuse-angle bends, reduces the amount of pipe wall adhesion, and lowers the resistance inside the pipeline, thereby slowing down the rapid rise in pressure inside the pipeline, avoiding the need to restart production after shutdown and pressure reduction, replacing the use of a conversion plate, improving production efficiency, and reducing the idle time of the production system.

[0019] 2. In this utility model, the first connector and the second connector are connected to the two ends of the short pipe by threads, which can realize the fine adjustment of the length of the short pipe to adapt to the actual required length of the short pipe.

[0020] 3. This utility model, by setting buckles, locking pins and unlocking devices, realizes the functions of quick insertion and locking and pressing the unlocking plate to unlock the short pipe connector, thereby enabling quick disassembly. It is convenient to use and quick and easy to assemble and disassemble. Attached Figure Description

[0033] Please see Figures 2 to 8 This utility model provides a technical solution:

[0034] A pipeline shorting structure for pressure reduction in a shortening production system includes:

[0035] The production system includes a quench mixer 1, a kneading mixer 2, and a small kneading mixer 3. Ports A1, A2, A3, and A4 of the quench mixer 1 are connected in sequence through several short connecting pipes 6. Port A4 of the quench mixer 1 is connected to port B1 of the kneading mixer 2 through several short connecting pipes 6. Ports B1, B2, B3, and B4 of the quench mixer 1 are connected in sequence through several short connecting pipes 6. Port B4 of the kneading mixer 2 is connected to the small kneading mixer 3 through several short connecting pipes 6.

[0036] The short pipes 6 are connected end to end in sequence and fixedly connected by a connector device, which is unlocked by an unlocking device.

[0037] Specifically, such as Figure 5 and Figure 6 As shown, one end of the short connector 6 is provided with a plug connector 603, and the other end is provided with a plug hole 604. The outer diameter of the plug connector 603 is smaller than the outer diameter of the short connector 6, and the inner diameter of the plug hole 604 is equal to the outer diameter of the plug connector 603. The plug connector 603 and the plug hole 604 cooperate to connect the short connectors 6 end to end in sequence.

[0038] Specifically, the insertion tube 603 and the insertion hole 604 are interference-fitted to ensure the sealing of the short tube 6.

[0039] Specifically, such as Figure 5 As shown, the short pipe 6 has a first external thread 601 at one end and a second external thread 602 at the other end. The connector device includes a first connector 7 and a second connector 8. The first connector 7 has a first internal thread 702 in the middle, and the second connector 8 has a second internal thread 801. The first internal thread 702 is connected to the first external thread 601, and the second internal thread 801 is connected to the second external thread 602, so that the first connector 7 and the second connector 8 are respectively fitted onto the two ends of the short pipe 6.

[0040] Specifically, the length of the short pipe 6 is preferably 1m, and the lengths of the first external thread 601 and the second external thread 602 are preferably 0.3m. The length of the connection between the first connector 7 and the second connector 8 is adjusted by the threads of the short pipe 6. The adjustment range is 1m-1.3m, that is, the shortest threaded connection length of the first connector 7 and the second connector 8 is 0.15m (half of the thread length) to ensure the strength of the threaded connection.

[0041] Specifically, such as Figure 5As shown, one end of the first connector 7 is provided with a plurality of buckles 701, which are arranged in a central array. One end of the second connector 8 is provided with a plurality of snap-fit ​​cavities 802, which are the same in number and spacing angle as the buckles 701. The buckles 701 of the other short pipe 6 connected to it are inserted into the snap-fit ​​cavity 802.

[0042] Specifically, to ensure balanced force distribution, the number of the buckles 701 and the snap-fit ​​cavities 802 is preferably 6, and the spacing angle is preferably 60°.

[0043] Specifically, such as Figure 7 As shown, the snap-fit ​​cavity 802 is provided with a snap-fit ​​pin 13, which is wedge-shaped. A snap-fit ​​connecting rod 11 is provided on the side of the snap-fit ​​pin 13, and a spring 12 is sleeved on the snap-fit ​​connecting rod 11. When the snap-fit ​​buckle 701 is inserted into the snap-fit ​​cavity 802, the snap-fit ​​buckle 701 pushes the snap-fit ​​pin 13 in the direction of compression of the spring 12. The length of the snap-fit ​​pin 13 is less than the length of the snap-fit ​​buckle 701. When the snap-fit ​​buckle 701 is fully inserted into the snap-fit ​​cavity 802, the spring 12 returns to its original state, so that the snap-fit ​​pin 13 moves inward and locks the snap-fit ​​buckle 701.

[0044] Specifically, the surface of the locking pin 13 is hardened and polished, preferably with a surface roughness of Ra1.6μm, in order to reduce the friction between the locking pin 13 and the buckle 701 when they move relative to each other, making the insertion of the buckle 701 smoother.

[0045] Specifically, such as Figure 7 As shown, the second connector 8 is provided with a connecting rod through hole 803, and the other end of the locking pin connecting rod 11 passes through the connecting rod through hole 803 and is connected to the unlocking device.

[0046] Specifically, such as Figure 8 As shown, the unlocking device includes an unlocking pressure plate 9, a rotating shaft 14, and a support frame 10. The support frame 10 is fixedly mounted on the outer surface of the second connector 8. The support frame 10 has a second rotating shaft through hole 1001. One end of the unlocking pressure plate 9 is fixedly connected to the locking pin connecting rod 11. The side of the unlocking pressure plate 9 has a first rotating shaft through hole 901. The support frame 10 is located on both sides of the unlocking pressure plate 9. The rotating shaft 14 passes through the first rotating shaft through hole 901 and the second rotating shaft through hole 1001. The unlocking pressure plate 9 rotates around the rotating shaft 14. When the free end of the unlocking pressure plate 9 is pressed, the end of the unlocking pressure plate 9 connected to the locking pin connecting rod 11 moves in the opposite direction, thereby driving the locking pin 13 to move towards the outer side of the short pipe 6.

[0047] Specifically, such as Figure 8As shown, the free end of the unlocking pressure plate 9 is tilted outwards towards the short tube 6 to increase the pressing torque, thereby making the process of pressing the unlocking pressure plate 9 easier.

[0048] In this embodiment, when connecting the short tube 6, firstly, the first connector 7 and the second connector 8 are connected to both ends of the short tube 6 by threads and adjusted to a suitable length. Then, the insertion tube 603 on the short tube 6 is inserted into the insertion hole 604 at the tail end of the other short tube 6. The second connector 8 on the other short tube 6 cooperates with the first connector 7 of the short tube 6. The buckle 701 of the other short tube 6 is inserted into the snap-fit ​​cavity 802 of the short tube 6. When the buckle 701 is inserted into the snap-fit ​​cavity 802, it pushes the locking pin 13 outward to compress the spring 12. Since the length of the locking pin 13 is less than the length of the buckle 701, when the buckle 701 is fully inserted into the snap-fit ​​cavity 802, the spring 12 rebounds, so that the locking pin 13 locks the buckle 701, thereby achieving a fixed connection of the short tube 6. This process only requires aligning and inserting the buckle 701 with the snap-fit ​​cavity 802, which is simple, convenient and quick.

[0049] In this embodiment, when the short tube 6 is unlocked, the free end of the unlocking pressure plate 9 is pressed towards the center of the short tube 6. The free end of the unlocking pressure plate 9 rotates around the rotating shaft 14 towards the center of the short tube 6, thereby driving the end of the unlocking pressure plate 9 connected to the locking pin connecting rod 11 to move in the opposite direction, thereby driving the locking pin 13 to move so that the locking pin 13 leaves the buckle 701. The buckle 701 can be pulled outward. When the force pressing the unlocking pressure plate 9 is released, the locking pin 13 and the unlocking pressure plate 9 automatically return to their original state due to the rebound of the spring 12.

[0050] In this embodiment, the pipeline length is shortened by using the short connector 6, which reduces the number of right-angle and obtuse-angle bends, reduces the amount of pipe wall adhesion, and lowers the resistance inside the pipeline. This slows down the rapid rise in pressure inside the pipeline, avoids restarting production after shutdown and pressure reduction, improves production efficiency, and reduces the idle time of the production system. Specific comparisons are shown in Table 1.

[0051] Table 1. Comparison of connecting pipes and elbows after the modification of each unit of the processing machine.

[0052]

[0053] As shown in the table above, the pipeline length in Unit A is reduced by 53.76m, the number of right-angle bends is reduced by 36, and the number of obtuse-angle bends is reduced by 5; the pipeline length in Units B and C is reduced by 47.20m, the number of right-angle bends is reduced by 49, and the number of obtuse-angle bends is reduced by 12.

[0054] In this embodiment, the pressure changes after modification by the short pipe 6 are shown in Table 2.

Among them, the continuous batch test of the shortening CNO25 short pipe for 13 batches has met the pressure requirements for daily continuous production.
