Description

Technical Field

[0001] The utility model relates to the technical field of glass-lined reaction containers, in particular to a glass-lined vacuum distillation kettle. Background Art

[0002] Distillation utilizes the different boiling points of the various components of a liquid mixture to separate the mixture by evaporating the lower-boiling-point material, then condensing and collecting the evaporated material. A glass-lined still is a composite material made by lining the inner surface of a steel container with high-silicon dioxide glass. This is then fired at high temperatures to firmly adhere to the metal surface. It is an excellent corrosion-resistant piece of equipment.

[0003] After searching, a Chinese patent with announcement number CN216320027U discloses a glass-lined distillation kettle. The glass distillation kettle drives the driving shaft to rotate by a stirring motor, so that the driving gear at one end of the driving shaft drives the driven gear to rotate, and the driven gear drives the stirring shaft to rotate. The stirring rod on the side wall of the stirring shaft stirs the material in the distillation kettle, which facilitates the distillation kettle to evaporate and separate the low-boiling-point materials. The low-boiling-point materials in the mixed material in the distillation kettle are evaporated into water vapor, which floats into the condensation tank for condensation and flows along the side wall of the condensation tank to the condensation collection plate. The glass distillation kettle has a simple structure, stable operation, corrosion resistance, high practicality, simple operation and high work efficiency.

[0004] However, in the above technical solution, when the stirring rod is stirring, the stirring rod will cause the liquid level in the peripheral part of the liquid in the reactor to rise, and the liquid level in the central part will naturally drop, thus forming a large vortex. Especially near the center, there is almost no velocity gradient between different liquid layers, thereby forming a so-called "solid rotation part" of the poor mixing zone, which makes it unable to be fully stirred, resulting in relatively low mixing and heat transfer efficiency.

DETAILED DESCRIPTION

[0034] Example 1

[0035] like Figure 1-5 As shown, the glass-lined vacuum distillation kettle proposed in the present invention includes a distillation kettle 1, a valve 2, a flange 3, a motor 4, a stirring assembly 5 and a head 12;

[0036] The end cap 12 is mounted on the upper end surface of the still 1 and is in communication with the still 1. A stirring assembly 5 is provided in the middle of the end cap 12, extending into the interior of the still 1 and causing the material inside the still 1 to change its layer structure when in use. The valve 2 is mounted at the discharge port of the still 1. Since the still 1 is used to distill corrosive materials, a solenoid valve is used for the valve 2 to ensure a safe working environment.

[0037] The motor 4 is mounted on the top of the head 12 and is in driving connection with the stirring assembly 5;

[0038] There are multiple flanges 3, all of which are installed on the head 12 and connected to the head 12 for connecting with external devices to transport materials and output steam into the distillation kettle 1. The flanges 3 can also be installed with components such as pressure detectors and thermometers, and the flanges 3 are equipped with flange covers when in use to maintain the pressure inside the distillation kettle 1.

[0039] In this embodiment, the external material conveying device, the steam condenser, and the pressure regulating device are respectively connected through multiple flanges 3 to convey the material to the inside of the distillation kettle 1. At the same time, the distillation kettle 1 is connected to the heat source to heat and evaporate the internal material. At the same time, the motor 4 drives the stirring component 5 to stir the material inside the distillation kettle 1, so that the material layer changes and the heating speed and evaporation efficiency are improved.

[0040] Example 2

[0041] like Figure 3-4 As shown, the present invention proposes a glass-lined vacuum distillation kettle. Compared with the first embodiment, the present embodiment differs in that the distillation kettle 1 further includes a kettle body 11 and a heating assembly 6;

[0042] The kettle body 11 is mounted on the lower end surface of the head 12 and is in communication with the head 12. The heating assembly 6 is mounted on the outside of the kettle body 11 and wrapped around the outer wall of the kettle body 11 for connecting to a heat source to heat and evaporate the material inside the kettle body 11.

[0043] The top of the kettle body 11 and the bottom of the head 12 are evenly provided with flange rings. The kettle body 11 and the head 12 are connected by bolts. When not in use, the head 12 is removed and the interior of the kettle body 11 and the stirring assembly 5 are cleaned and maintained.

[0044] In an optional embodiment, the heating assembly 6 includes a guide plate 61, a heating shell 62, a delivery pipe 63 and an insulation layer 64;

[0045] The guide plate 61 is installed on the outer wall of the kettle body 11. The guide plate 61 is a spiral plate and its height is less than the height of the kettle body 11. It is used to move the heat source around the kettle body 11 when the conveying pipe 63 conveys the heat source to the inside of the heating shell 62, so that the heat exchange between the heat source and the kettle body 11 is more uniform. It is also used to increase the heat transfer effect of the kettle body 11 when the contact area between the kettle body 11 and the heat source is large.

[0046] The heating shell 62 is wrapped around the outside of the guide plate 61 and is connected to the bottom end of the outer wall of the kettle body 11 and the top end of the guide plate 61. The kettle body 11 and the heating shell 62 are used as a heat source cavity, and the cavity is divided into a spiral cavity and a cavity by the guide plate 61. The heat source moves slowly when being transported to the inside of the heating shell 62, and completely wraps the kettle body 11 at the inner bottom end of the heating shell 62, thereby improving the heating effect of the lowest end of the material inside the kettle body 11.

[0047] There are two delivery pipes 63, which are respectively installed at the top and bottom ends of the cavity formed between the heating shell 62, the guide plate 61 and the kettle body 11 to input the heat source into the inside of the heating shell 62 and output the heat source after heat exchange to avoid the temperature inside the kettle body 11 from dropping.

[0048] The heat-insulating layer 64 is wrapped around the outside of the heating shell 62 and connected to the kettle body 11 for maintaining the temperature of the heating shell 62 in the working state to prevent the heat source temperature from not meeting the standard due to external factors.

[0049] In this embodiment, the material is placed in the kettle body 11 and connected to the heating device through the top conveying pipe 63 to convey the heat source to the inner side of the heating shell 62. The heat source moves through the guide spiral of the guide plate 61 to evenly exchange heat with the kettle body 11. Because the height of the guide plate 61 is smaller than the height of the kettle body 11, after the guide plate 61 completes the diversion, the personnel are spread over the inner bottom end of the heating shell 62 to heat the outer side of the bottom end of the kettle body 11 as a whole. At the same time, the insulation layer 64 provides environmental protection for the personnel to avoid the temperature drop of the heat source caused by external factors. Finally, the heat source after heat exchange is discharged through the conveying pipe 63 at the lowest end.

[0050] Example 3

[0051] like Figure 3 and Figure 5 As shown, the glass-lined vacuum distillation kettle proposed by the present invention, compared with the first embodiment, this embodiment further describes in detail the specific structure of the stirring assembly 5 including the rotating shaft 51, the connecting plate 52, the supporting plate 53 and the stirring plate 54;

[0052] The rotating shaft 51 passes through and is rotatably mounted in the middle of the head 12;

[0053] The stirring plate 54 is mounted on the lower end surface of the rotating shaft 51 and is arranged in an inclined manner, wherein the lower end surface of the rotating shaft 51 is connected to the upper inclined surface of the stirring plate 54. The two ends of the stirring plate 54 are inclined in the same direction. In the working state, the two ends of the stirring plate 54 can respectively drive the material to move up and down, thereby preventing the material from swirling inside the distillation kettle 1, resulting in the material not being able to be fully and quickly heated and evaporated.

[0054] The connecting plate 52 is installed on the outside of the rotating shaft 51 and is located above the stirring plate 54 to fix the supporting plate 53 and enable the supporting plate 53 to exert force on the stirring plate 54;

[0055] The support plates 53 are respectively installed between the end of the rotating shaft 51 and the end of the stirring plate 54, and there are two support plates 53; the two support plates 53 are both arranged in an inclined shape and arranged according to the central annular array of the rotating shaft 51. When in use, the inclined support plates 53 drive the axial movement of the material, and have an upward or downward thrust, thereby changing the upper and lower layer positions of the material.

[0056] In an optional embodiment, the bottom ends of the two support plates 53 are respectively installed at the top of one end of the inclined surface of the stirring plate 54 and the bottom of the other end of the inclined surface of the stirring plate 54. When the rotating shaft 51 drives the stirring plate 54 to rotate, the two support plates 53 connected to the ends of the stirring plate 54 generate pulling force and supporting force on the stirring plate 54, thereby preventing the ends of the stirring plate 54 from bending during rotation.

[0057] In summary, when the present invention is in use, the external material conveying device, the steam condenser, and the pressure regulating device are connected respectively through multiple flanges 3 to convey the material to the inner side of the kettle body 11, and the heating device is connected through the top conveying pipe 63 to convey the heat source to the inner side of the heating shell 62. The heat source moves through the guide spiral of the guide plate 61 to evenly exchange heat with the kettle body 11. Because the height of the guide plate 61 is smaller than the height of the kettle body 11, after the guide plate 61 has completed the diversion, the personnel are spread over the inner bottom end of the heating shell 62 to heat the outer side of the bottom end of the kettle body 11 as a whole. At the same time, the thermal insulation layer 64 provides environmental protection for the personnel to avoid the temperature drop of the heat source caused by external factors. Finally, the heat source after heat exchange is discharged through the conveying pipe 63 at the lowest end, and the circulating heating work is carried out. During heating, the motor 4 is started to make the rotating shaft 51 drive the connecting plate 52 and the stirring plate 54 to rotate in the material. Because of the installation method and installation angle of the stirring plate 54, the two ends to the center of the stirring plate 54 have the force to push the material downward and upward respectively, so that it stirs the material and prevents the material from axially moving at the same level. At the same time, the connecting plate 52 and the stirring plate 54 drive the support plate 53 to rotate, stirring the material in one step. At the same time, the support plate 53 and the stirring plate 54 in the relative inclined direction with the stirring plate 54 work relative to each other, pushing the material close to the inner wall of the kettle body 11 downward and upward, so that the material inside the distillation kettle 1 is fully stirred, improving the heating and evaporation efficiency. At the same time, since the connecting plate 52, the support plate 53 and the stirring plate 54 are connected at one time, and the support plate 53 is located at the end of the connecting plate 52 and the stirring plate 54, the support plate 53 will withstand the resistance to the rotation of the stirring plate 54, thereby improving the service life and stability of the stirring plate 54. Finally, the steam is transported to the condenser through the flange 3 for condensation.

[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
