Description

Technical Field

[0001] This utility model relates to the field of fatty acid hydrolysis production technology, and more specifically, it relates to a device for improving the yield of hydrolyzed fatty acids. Background Technology

[0002] A device for improving the yield of hydrolyzed fatty acids is a specialized piece of equipment used to improve the hydrolysis efficiency and product yield in the production process of fatty acids. This device is mainly used in the oleochemical industry to improve the yield and quality of fatty acids by optimizing hydrolysis process parameters and reaction conditions.

[0003] In the process of fatty acid hydrolysis, pressure control in the reactor is a key factor affecting product yield. Existing hydrolysis devices usually use fixed pressure valves, which are difficult to adjust in a timely manner according to different raw material characteristics and process requirements once set. This fixed pressure control method not only limits the optimization space of process parameters, but also cannot adapt to the processing needs of different batches of raw materials, thus affecting the conversion efficiency and quality stability of the product.

[0004] In actual production, the pressure inside the reactor needs to be dynamically adjusted due to changes in raw material composition, reaction temperature and other factors. However, the pressure adjustment device of traditional equipment has a complex structure, the adjustment process is cumbersome and the pressure is prone to instability. This not only increases the difficulty of the operator's work, but also poses safety hazards. At the same time, it is difficult to ensure that the hydrolysis reaction is carried out under the optimal pressure conditions, resulting in low fatty acid yield and low production efficiency.

[0011] The present invention is further configured such that a connecting rod is provided on the top surface of the sealing block, the connecting rod being polygonal and slidably connected to the sealing plate.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a device for improving the yield of hydrolyzed fatty acids, which has the following beneficial effects:

[0018] 1. By setting a pressure relief mechanism at the top of the reactor, and employing a combination design of a sealing block, sliding hole, and sliding rod inside the pressure relief pipe, along with the sealing structure of the leakage hole and sealing ring, and the pressure control of the sealing plate, automatic pressure regulation of the reactor is achieved. When the pressure exceeds the set value, the sliding rod drives the sealing plate to move upward, and the excessive pressure is released in time through the pressure relief channel formed by the leakage hole and sliding hole, effectively solving the problem of inflexible pressure control in traditional devices. By setting a pressure regulating mechanism, utilizing the rotational cooperation between the rotating sleeve and the connecting plate, combined with the threaded transmission of the screw and the mating sleeve, and through the linkage design of the regulating sleeve, compression spring, and abutment ring, precise adjustment of the sealing plate pressure is achieved. With the sliding guidance of the guide strip and guide groove, the smooth and reliable adjustment process is ensured, solving the problem of inconvenient pressure regulation in existing technologies.

[0019] 2. By setting a limiting mechanism on the outside of the rotating sleeve, the sliding fit between the mounting ring and the limiting block, combined with the elastic return of the return spring and the positioning function of the limiting groove, and through the linkage design of the push spring and the limiting sleeve, the position of the rotating sleeve is reliably locked. The arc-shaped limiting block design and the beveled limiting sleeve design, together with the buffering effect of the relief groove, ensure the flexible operation and reliable fixation of the limiting mechanism.

[0020] 3. By setting up a stirring mechanism in the reactor and using a motor-driven rotating rod, combined with the three-dimensional stirring of multiple sets of stirring paddles and the bottom cleaning function of the scraper, the reactants are fully mixed.

[0030] Please see Figures 1-5 A device for improving the yield of hydrolyzed fatty acids includes a support frame 1, a connecting frame 2 connected to the support frame 1, a reaction vessel 3 mounted at the bottom of the connecting frame 2, a heating system 4 on the outside of the reaction vessel 3, and a pressure relief mechanism at the top of the reaction vessel 3. The pressure relief mechanism includes a pressure relief pipe 5, a sealing block 6, sliding holes 7, a sliding rod 8, a leak hole 9, a sealing ring 10, a sealing plate 11, and a pressure regulating mechanism. The pressure relief pipe 5 is connected to the top of the reaction vessel 3, the sealing block 6 is installed inside the pressure relief pipe 5, multiple sets of sliding holes 7 are distributed on the sealing block 6, the sliding rod 8 slides within the multiple sets of sliding holes 7, and multiple sets of leak holes 9 are distributed on the outer wall of the sealing block 6 and communicate with the multiple sets of sliding holes 7 respectively. A sealing ring 10 is installed on the inner wall of the pressure relief pipe 5. A sealing plate 11 is installed on the top of multiple sets of sliding rods 8 and abuts against the sealing ring 10. The pressure regulating mechanism includes a rotating sleeve 12, a connecting plate 13, a screw 14, a mating sleeve 15, an adjusting sleeve 16, a compression spring 17, and an abutting ring 18. The rotating sleeve 12 is rotatably installed on the top of the pressure relief pipe 5. The connecting plate 13 is installed inside the rotating sleeve 12. The screw 14 is connected to the bottom surface of the connecting plate 13. The mating sleeve 15 is threadedly connected to the outer wall of the screw 14. The adjusting sleeve 16 is installed on the outer wall of the mating sleeve 15. Multiple sets of compression springs 17 are connected to the bottom surface of the adjusting sleeve 16. The abutting ring 18 is installed at the bottom end of multiple sets of compression springs 17 and abuts against the sealing plate 11.

[0031] A limiting mechanism is provided on the outer side of the rotating sleeve 12. The limiting mechanism includes a mounting ring 19, a limiting block 20, a reset spring 21, a limiting groove 22, a push spring 23, and a limiting sleeve 24. The mounting ring 19 is provided on the outer wall of the pressure relief pipe 5. Multiple sets of limiting blocks 20 are provided and slidably mounted on the mounting ring 19. The reset spring 21 is connected to the outer wall of the multiple sets of limiting blocks 20 and is connected to the inner wall of the mounting ring 19. Multiple sets of limiting grooves 22 are provided and distributed on the outer wall of the rotating sleeve 12. Multiple sets of push springs 23 are provided and mounted on the outer wall of the pressure relief pipe 5. The limiting sleeve 24 is mounted on the top of the multiple sets of push springs 23.

[0032] The inner wall of the pressure relief pipe 5 is provided with guide strips 25, and multiple sets of guide strips 25 are provided. The outer walls of the adjusting sleeve 16 and the sealing plate 11 are both provided with guide grooves 26, and multiple sets of guide grooves 26 are provided, each of which is slidably connected to multiple sets of guide strips 25. The principle is that the sliding of the guide strips 25 and the guide grooves 26 provides a stable movement track for the adjusting sleeve 16 and the sealing plate 11, preventing them from deviating during movement.

[0033] The top surface of the sealing block 6 is provided with a connecting rod 27, which is polygonal and slidably connected to the sealing plate 11. The principle is to use the polygonal structure of the connecting rod 27 to form a directional sliding fit with the sealing plate 11, ensuring that the sealing block 6 and the sealing plate 11 can only move in a straight line and will not rotate.

[0034] Multiple sets of limiting blocks 20 have rounded ends, and the limiting sleeve 24 has an angled top. The principle is that the rounded ends of the limiting blocks 20 and the angled design of the limiting sleeve 24 create a progressive push when they come into contact, making the movement of the limiting mechanism smoother.

[0035] The limiting sleeve 24 is provided with a clearance groove 28, and multiple sets of clearance grooves 28 are provided. The principle is that multiple sets of clearance grooves 28 provide the necessary space for the movement of the limiting block 20, so as to avoid interference between the limiting block 20 and the limiting sleeve 24 during the movement.

[0036] The top surface of the reactor 3 is equipped with a feed pipe 29, and multiple sets of feed pipes 29 are provided. The principle is to achieve multi-point dispersed feeding of raw materials through multiple sets of feed pipes 29, thereby improving feeding efficiency and ensuring uniform material distribution within the reactor 3.

[0037] In this embodiment, when the pressure inside the reactor 3 is too high, the pressure pushes multiple sets of sliding rods 8 to slide along the sliding holes 7. The multiple sets of sliding rods 8 push the sealing plate 11 to separate from the sealing ring 10. At the same time, the multiple sets of sliding rods 8 gradually disengage from the sealing holes 9. The pressure is leaked through the multiple sets of leak holes 9 and the sliding holes 7, and then discharged through the venting space between the sealing plate 11 and the sealing ring 10 to the pressure relief pipe 5, thereby releasing the pressure inside the reactor. When it is necessary to adjust the pressure relief value, the limiting sleeve 24 is pushed and the multiple sets of push springs 23 are squeezed, while the contact with the multiple sets of limiting blocks 20 is released. Then, the multiple sets of limiting blocks 20 are pulled outward by the multiple sets of reset springs 21, so that the multiple sets of limiting blocks 20 are disengaged from the limiting groove 22. Then, the rotating sleeve 12 is rotated. The connecting plate 13 and the screw 14 rotate, and the screw 14 rotates and engages with the mating sleeve 15. This causes the adjusting sleeve 16 to move within the pressure relief pipe 5 via the mating sleeve 15. The adjusting sleeve 16 slides along the guide bar 25 through multiple sets of guide grooves 26. The pressure of the abutment ring 18 on the sealing plate 11 is adjusted by the adjusting sleeve 16 and multiple sets of pressure springs 17, thereby achieving precise control of the pressure relief value. Then, the limiting sleeve 24 is released and pushed to slide by multiple sets of push springs 23. The oblique angle set at the top of the limiting sleeve 24 abuts against the arc surface of multiple sets of limiting blocks 20 and applies downward pressure. Subsequently, the tops of the multiple sets of limiting blocks 20 are engaged in the receiving groove and pushed to engage in the limiting groove 22, thereby limiting the rotation sleeve 12.

[0038] Please see Figure 2As one embodiment of the stirring mechanism: the reaction vessel 3 is provided with a stirring mechanism, which includes a rotating rod 30, a stirring paddle 31, a scraper 32 and a motor 33. The rotating rod 30 rotatably connects the reaction vessel 3 and the connecting frame 2. Multiple sets of stirring paddles 31 are fixed on the outer wall of the rotating rod 30. Multiple sets of scrapers 32 are installed at the bottom of the rotating rod 30 and connected to multiple sets of stirring paddles 31. The motor 33 is fixed on the top surface of the support frame 1 and its output end is fixedly connected to the rotating rod 30.

[0039] More specifically, the motor 33 drives the rotating rod 30 to rotate, which in turn drives multiple sets of stirring paddles 31 to stir the materials inside the reactor 3. Multiple sets of scrapers 32 at the bottom cooperate with the stirring paddles 31 to prevent materials from settling at the bottom of the reactor. Different raw materials can be added separately through multiple sets of feed pipes 29 to ensure the continuity of the reaction process.

[0040] In summary, during the use or operation of the overall equipment: when the pressure inside the reactor 3 is too high, the pressure pushes multiple sets of sliding rods 8 to slide along the sliding holes 7. These sliding rods 8 push the sealing plate 11 to separate from the sealing ring 10. Simultaneously, the sliding rods 8 gradually disengage from the sealing holes 9, allowing pressure to leak through the holes 9 and the sliding holes 7. The pressure is then discharged through the venting space between the sealing plate 11 and the sealing ring 10 into the pressure relief pipe 5, thus releasing the pressure inside the reactor. When it is necessary to adjust the pressure relief value, the limiting sleeve 24 is pushed, compressing multiple sets of push springs 23 and simultaneously releasing the contact with multiple sets of limiting blocks 20. Then, the multiple sets of limiting blocks 20 are pulled outwards by multiple sets of return springs 21, causing them to disengage from the limiting grooves 22. Finally, the reactor rotates... The moving sleeve 12 drives the connecting plate 13 and the screw 14 to rotate. The screw 14 rotates and engages with the mating sleeve 15 through a threaded connection. This causes the adjusting sleeve 16 to move within the pressure relief pipe 5 via the mating sleeve 15. The adjusting sleeve 16 slides along the guide bar 25 through multiple sets of guide grooves 26. The pressure of the abutment ring 18 on the sealing plate 11 is adjusted by the adjusting sleeve 16 and multiple sets of compression springs 17, thereby achieving precise control of the pressure relief value. Then, the limiting sleeve 24 is released and pushed to slide by multiple sets of push springs 23. The oblique angle set at the top of the limiting sleeve 24 abuts against the arc surface of multiple sets of limiting blocks 20 and applies downward pressure. Subsequently, the tops of the multiple sets of limiting blocks 20 are engaged in the receiving groove and pushed to engage in the limiting groove 22, thus limiting the rotating sleeve 12.

[0041] Motor 33 drives rotor 30 to rotate, which in turn drives multiple sets of stirring paddles 31 to stir the materials inside reactor 3. Multiple sets of scrapers 32 at the bottom cooperate with the stirring paddles 31 to prevent materials from settling at the bottom of the reactor. Different raw materials can be added separately through multiple feed pipes 29 to ensure the continuity of the reaction process.

[0042] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
