Description

Technical Field

[0001] The utility model relates to the technical field of preheating devices, and more specifically, to a non-edible vegetable oil preheater. Background Art

[0002] In the prior art, non-edible vegetable oil preheater is a key production equipment, especially in the extraction and solvent production process of non-edible vegetable oil. The main function of this preheater is to preheat the raw material through the heat exchange process, that is, the transfer of heat energy between the heat medium and the raw material. This process is crucial for subsequent chemical reactions and physical processes, because proper preheating can improve efficiency and ensure the smooth progress of the reaction.

[0003] However, most non-edible vegetable oil preheaters on the market currently use a welded structure design. Although this design can ensure the stability and sealing of the equipment, it has certain limitations in terms of maintenance and repair. Due to its poor disassembly, when the heat exchange tubes need to be repaired or cleaned, the operation process is time-consuming and laborious. In addition, this structure requires a lot of manpower and material resources during maintenance, which not only increases the maintenance cost, but also affects the overall operating efficiency of the equipment.

[0004] In addition, the internal piping structure of common non-edible vegetable oil preheaters is usually relatively simple. When maintaining or replacing the heat exchange tubes, the equipment must be disassembled. This design lacks a one-way sealing device, which may cause leakage of raw materials or heat media during the disassembly process. Leakage may not only cause material waste, but also cause pollution and safety hazards in the workplace, and in some cases may even cause more serious adverse effects due to misoperation.

[0005] Furthermore, due to the simple piping structure inside these preheaters, they are usually unable to achieve effective regulation of flow rate. This deficiency may lead to low heat exchange efficiency because the flow rate of raw materials or heat medium cannot be adjusted according to actual needs, which in turn affects the efficiency and effectiveness of the entire preheating process. In addition, improper flow rate may also lead to the accumulation of sediment inside the pipe, which in turn affects the long-term stable operation and maintenance cost of the preheater.

[0032] An unlocking sleeve 12 is arranged on the outer side of the delivery pipe 2 , a guide ring 13 is arranged on the inner side of the unlocking sleeve 12 , and a guide block 14 is arranged on one end of the push rod 8 .

[0033] A limiting sleeve 15 is provided on the outer side of the delivery pipe 2 , and one end of the unlocking sleeve 12 can be movably installed in the limiting sleeve 15 .

[0034] A second spring 16 is disposed in the limiting sleeve 15 , and one end of the second spring 16 is connected to the unlocking sleeve 12 .

[0035] A slider 17 is disposed on the outer side of the movable plate 11 , and a slide groove 18 is provided at a corresponding position of the inner wall of the delivery pipe 2 , and the slider 17 is slidably installed in the slide groove 18 .

[0036] A first spring 19 is disposed in the slide groove 18 , and one end of the first spring 19 is connected to the slide block 17 .

[0037] In this embodiment, when the heat exchange tube 5 is maintained or replaced, the unlocking sleeve 12 is pushed toward the direction of the delivery tube 2, and one end of the unlocking sleeve 12 moves in the limiting sleeve 15 and compresses the second spring 16 arranged on the inner side of the limiting sleeve 15. At the same time, the guide ring arranged on the inner side of the unlocking sleeve 12 moves with the unlocking sleeve 12. Due to the special structural design of the guide ring 13 and the guide block 14, the guide ring 13 squeezes the guide block 14 and causes the guide block 14 to move relatively outward. Then, the ejector rod 8 connected to one side of the guide block 14 follows the corresponding displacement and moves out of the slot 7. When the sleeve 6 is disengaged from the inside of the delivery pipe 2, the first spring 19 arranged in the slide groove 18 will be reset and push the slider 17 to move in the slide groove 18. At the same time, the flexible plate 10 will open and close and contract. When the flexible plate 10 is completely overlapped, the one-way sealing function can be realized to prevent leakage and operational errors. The heat exchange tube 5 is removed from one end of the delivery pipe 2. After the maintenance or replacement of the heat exchange tube 5 is completed, the heat exchange tube 5 is reconnected with the delivery pipe 2 with reference to the above process.

[0038] See also Figure 2 and Figure 4 , as an implementation method of a non-edible vegetable oil preheater for the adjustment mechanism: the adjustment mechanism includes an adjustment sleeve 20, a fixed plate 21, a screw 22 and a screw sleeve 23, one end of the adjustment sleeve 20 is movably connected to the heat exchange tube 5, the other end of the adjustment sleeve 20 is movably connected to the clamping sleeve 6, the fixed plate 21 is fixedly installed on one side of the clamping sleeve 6, the screw 22 is connected to one end of the movable plate 11, the screw sleeve 23 is fixedly connected to the fixed plate 21, and the screw sleeve 23 is movably connected to the screw 22 through a thread.

[0039] Sealing sleeves 24 are provided on both sides of the adjusting sleeve 20 , and the sealing sleeves 24 are fixedly connected to both sides of the adjusting sleeve 20 .

[0040] More specifically, when the output or input rate of the device needs to be adjusted, the adjusting sleeve 20 is rotated, and the adjusting sleeve 20 will drive the fixed plate 21 and the screw sleeve 23 to rotate. The setting of the sealing sleeve 24 can increase the sealing of the connection to prevent leakage. Since the slider 17 and the slide groove 18 arranged on the outside of the movable plate 11 have a mutual limiting effect, and the screw sleeve 23 and the screw rod 22 are movably connected through threads, when the screw sleeve 23 rotates, the movable plate 11 will slide relatively inside the conveying pipe 2, and the distance between the flexible plates 10 will be increased or reduced accordingly, thereby achieving the purpose of adjusting the flow rate.

[0041] In summary, when the overall equipment is in use or running: when the heat exchange tube 5 is maintained or replaced, the unlocking sleeve 12 is pushed in the direction of the conveying pipe 2, one end of the unlocking sleeve 12 moves in the limiting sleeve 15, and compresses the second spring 16 arranged on the inner side of the limiting sleeve 15, and at the same time, the guide ring arranged on the inner side of the unlocking sleeve 12 moves with the unlocking sleeve 12. Due to the special structural design of the guide ring 13 and the guide block 14, the guide ring 13 squeezes the guide block 14 and prompts the guide block 14 to move relatively outward, and then the push rod 8 connected to one side of the guide block 14 follows the corresponding displacement and When the clamping sleeve 6 is removed from the inside of the delivery pipe 2, the first spring 19 arranged in the slide groove 18 will be reset and push the slider 17 to move in the slide groove 18. At the same time, the flexible plate 10 will open and close and contract. When the flexible plate 10 is completely overlapped, the one-way sealing function can be realized to prevent leakage and operational errors. The heat exchange tube 5 is removed from one end of the delivery pipe 2. After the maintenance or replacement of the heat exchange tube 5 is completed, the heat exchange tube 5 is reconnected with the delivery pipe 2 with reference to the above process.

[0042] When the output or input rate of the device needs to be adjusted, the adjusting sleeve 20 is rotated, and the adjusting sleeve 20 will drive the fixed plate 21 and the screw sleeve 23 to rotate. The setting of the sealing sleeve 24 can increase the sealing of the connection to prevent leakage. Since the slider 17 and the slide groove 18 arranged on the outside of the movable plate 11 have a mutual limiting effect, and the screw sleeve 23 and the screw rod 22 are movably connected through threads, when the screw sleeve 23 rotates, the movable plate 11 will slide relatively inside the conveying pipe 2, and the distance between the flexible plates 10 will be increased or reduced accordingly, thereby achieving the purpose of adjusting the flow rate.

[0043] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model.
