Description

Technical Field

[0001] The utility model relates to the technical field of oleic acid distillation devices, in particular to a distillation device for oleic acid production. Background Art

[0002] Oleic acid is an important chemical raw material and is widely used in many industrial fields, such as oil processing, surfactants, lubricants and additives. Oleic acid is usually extracted from plant or animal oils and obtained through acidification and separation processes. Subsequently, it is necessary to use a distillation device to further purify and separate oleic acid to meet specific market needs. During distillation, the internal pressure of the distillation tank is high, so a pressure relief valve is required to relieve the pressure in order to reduce the pressure inside the distillation tank.

[0003] In the prior art, the existing distillation apparatus usually releases pressure through a pressure relief valve during the distillation process. However, when the amount of oleic acid to be distilled is small, the pressure relief valve cannot effectively adjust the pressure to be discharged, resulting in excessive pressure release, which will cause the temperature and vaporization efficiency of oleic acid distillation to decrease, thereby affecting the stability and efficiency of the production process. As a result, the use effect of the distillation apparatus is poor and the effect of oleic acid distillation is adversely affected.

[0004] Therefore, a distillation device for oleic acid production is needed to solve the problem that the existing distillation device cannot adjust the pressure that needs to be released, resulting in excessive pressure release, thereby affecting the distillation effect of oleic acid.

[0025] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] See also Figure 1-Figure 8 The utility model provides a technical solution: a distillation device for oleic acid production, comprising a distillation device body 1, a material receiving box 2 is installed at the bottom of the distillation device body 1, an exhaust pipe 3 is installed on the right side of the top of the distillation device body 1, a fixed pipe 4 is installed on the upper side of the inner wall of the exhaust pipe 3, an exhaust plate 11 is installed at the bottom end of the fixed pipe 4, a fixed column 7 is installed on the top of the exhaust plate 11, a piston 6 is sleeved on the outer side of the fixed column 7, and a fixed cover 5 is installed on the outer side of the upper part of the fixed pipe 4; the piston 6 is slidably connected to the inner wall of the fixed pipe 4, and the bottom of the piston 6 is attached to the top of the exhaust plate 11, so that the pressure inside the distillation device body 1 pushes the piston 6 to slide upward along the inner wall of the fixed pipe 4, and then the pressure inside the distillation device body 1 is conveniently released through the exhaust plate 11 and the exhaust pipe 3.

[0028] First, oleic acid is injected into the interior of the distillation device body 1 for distillation. At this time, the internal pressure of the distillation device body 1 will increase, thereby pushing the piston 6 to slide upward along the outer side of the fixed column 7 and allowing its bottom to separate from the exhaust plate 11. At this time, the pressure is released outward through the exhaust plate 11 and the fixed tube 4. When a certain pressure is released, the piston 6 will slide downward along the inner wall of the fixed tube 4, and at the same time, its bottom will fit on the top of the exhaust plate 11, thereby blocking the exhaust holes in the middle of the exhaust plate 11 and the outer side of the lower part of the fixed tube 4, thereby preventing the pressure from being released, thereby improving the distillation effect of the distillation device body 1. At the same time, the distilled oleic acid will flow to the inside of the receiving box 2 for storage.

[0029] Embodiment 2

[0030] On the basis of Example 1, in order to adjust the elastic force of the spring 10 so as to increase the pressure of the piston 6 and thus facilitate the adjustment of the released pressure, a knob 8 is installed on the top of the fixed cover 5, and a screw 9 is installed at the bottom of the knob 8. The upper outer side of the screw 9 is threadedly connected to a movable plate 19, and a spring 10 is installed at the bottom of the movable plate 19; the screw 9 passes through the top of the fixed cover 5, and the bottom end is rotatably connected to the top of the fixed column 7, so that the screw 9 is driven to rotate by turning the knob 8, and then the movable plate 19 is driven to move downward, and the movable plate 19 is slidably connected to the inner wall of the fixed tube 4, and both sides of the movable plate 19 slide in the slide groove of the upper inner wall of the fixed tube 4, so that the spring 10 is squeezed by adjusting the movable plate 19 downward, thereby increasing the pressure of the piston 6, and the bottom end of the spring 10 is installed on the top of the piston 6.

[0031] When it is necessary to adjust the discharge pressure, first turn the knob 8 to drive the screw 9 to rotate, and at the same time drive the movable plate 19, and let its two sides slide downward along the inner wall groove of the fixed tube 4, and squeeze the spring 10 at the same time. At this time, since the spring 10 is squeezed, the pressure of the piston 6 is increased. After the adjustment is completed, when the internal pressure of the distillation device body 1 reaches the adjusted pressure, the piston 6 will move upward along the inner wall of the fixed tube 4 and squeeze the spring 10. When the pressure is released below the preset value, the spring 10 will push the piston 6 to move downward and reset it, so as to facilitate the workers to adjust the pressure to be released and prevent excessive pressure release from causing low temperature and vaporization efficiency during oleic acid distillation.

[0032] Embodiment 3

[0033] On the basis of the second embodiment, in order to increase the sealing between the exhaust pipe 3 and the distillation device body 1 and facilitate the replacement of the rubber plate 13, a plurality of mounting grooves 18 are opened on the upper outer side of the exhaust pipe 3, and the inner wall of the mounting groove 18 is plugged with a plug-in block 14. A fixing ring 16 is installed on the side of the plurality of plug-in blocks 14 away from the exhaust pipe 3, and a rubber plate 13 is installed on the bottom of the fixing ring 16. The bottom of the rubber plate 13 is attached to the top of the distillation device body 1, and the rubber plate 13 is sleeved on the outer side of the bottom of the exhaust pipe 3, thereby increasing the sealing between the exhaust pipe 3 and the distillation device body 1. The fixing ring 16 is sleeved on the outer side of the exhaust pipe 3, so that by pulling the fixing ring 16 upwards and driving the rubber plate 13 to move upward, the rubber plate 13 can be easily removed for replacement.

[0034] When the rubber sheet 13 needs to be replaced, first pull the fixing ring 16 upwards to let it slide along the outer side of the fixing tube 4, and at the same time drive the plug-in block 14 out of the mounting groove 18, thereby driving the rubber sheet 13 out of the top of the distillation device body 1, and then pull it upwards and let it out of the fixing cover 5, so as to facilitate the replacement of the rubber sheet 13. After completion, the rubber sheet 13 is reset, and the plug-in block 14 is plugged into the inner wall of the mounting groove 18, so as to increase the sealing between the fixing tube 4 and the distillation device body 1 to prevent pressure leakage.

[0035] Embodiment 4

[0036] On the basis of Example 3, in order to improve the stability of the installation of the rubber plate 13, a plurality of clamping columns 15 are installed at the bottom of the rubber plate 13, and a rubber ring 17 is sleeved on the outer side of the clamping column 15, and a plurality of clamping grooves 12 are opened on the right side of the top of the distillation device body 1; the clamping column 15 is inserted into the inner wall of the clamping groove 12, and the rubber ring 17 is installed on the inner wall of the clamping groove 12, so that the rubber ring 17 is used to increase the friction between the clamping column 15 and the clamping groove 12, thereby increasing the installation firmness between the rubber plate 13 and the distillation device body 1.

[0037] When the rubber plate 13 is installed downward, since a plurality of posts 15 are installed at the bottom of the rubber plate 13 and a rubber ring 17 is sleeved on the outer side of the post 15, when the post 15 is inserted into the inner wall of the slot 12, the rubber ring 17 will be deformed on the inner wall of the slot 12 and move downward. When the post 15 is completely reset, the rubber ring 17 will be engaged with the inner wall of the slot 12, thereby increasing the friction between the rubber plate 13 and the distillation device body 1, thereby improving the stability of the rubber plate 13 after installation.

[0038] In actual use, oleic acid is first injected into the interior of the distillation device body 1 for distillation. At this time, the internal pressure of the distillation device body 1 will increase, thereby pushing the piston 6 to slide upward along the outer side of the fixed column 7 and allowing its bottom to separate from the exhaust plate 11. At this time, the pressure is released outward through the exhaust plate 11 and the fixed tube 4. When a certain pressure is released, the piston 6 will slide downward along the inner wall of the fixed tube 4, and at the same time, its bottom will fit on the top of the exhaust plate 11, thereby blocking the exhaust holes in the middle of the exhaust plate 11 and the outer side of the lower part of the fixed tube 4, thereby preventing the pressure from being released, thereby improving the distillation effect of the distillation device body 1. At the same time, the distilled oleic acid will flow to the inside of the receiving box 2 for storage.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
