Description

Technical Field

[0001] The present invention relates to the technical field of distillation equipment, and particularly to a Litsea cubeba oil distillation equipment with an anti-blocking function. Background Art

[0002] Litsea cubeba oil refers to the natural essential oil extracted from fresh Litsea cubeba fruits. It is slightly yellowish and contains a large amount of citral, so it has a very strong and pleasant lemon smell, which is approximately between floral and fruity scents. The main chemical components it contains are: citral, limonene, methyl heptenone, coriander oil alcohol, geraniol, vanillin, camphene, etc.

[0003] Distillation is a thermodynamic separation process. It utilizes the different boiling points of each component in a mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire component unit operation process, which is a combination of two unit operations: evaporation and condensation.

[0004] When distilling Litsea cubeba oil, its liquid will contain some impurities (during the distillation process of Litsea cubeba, the rising gas flow often accompanies Litsea cubeba (solid matter) or fruit peels). These impurities will adhere to the pipe wall along with the liquid when passing through the gas-solid separator or at the variable diameter or elbow of the secondary steam pipe. As the service life of the equipment increases, these attachments will gradually increase and reduce the cross-section of gas flow, ultimately resulting in blockage.

[0005] In order to avoid or slow down the occurrence of blockage, the present application proposes a Litsea cubeba oil distillation equipment with an anti-blocking function. Summary of the Invention

[0006] In view of the above-mentioned disadvantages of the prior art, the purpose of the present invention is to provide a Litsea cubeba oil distillation equipment with an anti-blocking function, which is used to solve the problem of avoiding blockage inside the gas-solid separator in the prior art.

[0009] Inside the separation cylinder, a liquid separation plate and a gas-solid separation part are respectively arranged from bottom to top. The liquid separation plate supports the gas-solid separation part. The gas-solid separation part is driven to rotate by the mixed gas input through the feed pipe in a tangential direction, and the inner wall is cleaned by contacting and rubbing against the separation cylinder.

[0010] Preferably, the liquid separation plate includes a dish-shaped plate. A support connecting piece is arranged on the outer surface of the dish-shaped plate. A bearing seat is arranged at the center of the top of the dish-shaped plate. The gas-solid separation part is connected to the dish-shaped plate through the bearing seat.

[0011] A gap is left between the side wall of the dish-shaped plate and the inner wall of the separation cylinder.

[0012] Preferably, the dish-shaped plate is an inverted dish shape.

[0013] Preferably, the gas-solid separation part includes a support shaft rod. The lower end of the support shaft rod is inserted into the bearing seat. A plurality of pneumatic separation blades are equidistantly arranged on the outer surface of the support shaft rod. The pneumatic separation blades are lapped with the inner wall of the separation cylinder.

[0014] Preferably, a cleaning cutter head is arranged at one end of the pneumatic separation blade facing the inner wall of the separation cylinder. The cleaning cutter head bifurcates into a Y shape on both sides, and the end of the cleaning cutter head is attached to the inner wall of the separation cylinder.

[0015] Preferably, the lower end of the exhaust pipe extends into the separation cylinder. There is a distance between the lower end of the exhaust pipe and the inner top of the separation cylinder.

[0016] Preferably, a spoiler is arranged between the bottom of the exhaust pipe and the top of the pneumatic separation blade inside the separation cylinder.

[0017] The center of the spoiler is penetrated by the support shaft rod. The diameter of the spoiler is larger than the inner diameter of the exhaust pipe.

[0018] A gap is left between the outer surface of the spoiler and the inner wall of the separation cylinder.

[0019] Preferably, an air vibration part is arranged at the end of the support shaft rod. The air vibration part is arranged at the mouth of the lower end of the exhaust pipe and can be driven by the airflow.

[0020] Preferably, the air vibration part includes a plurality of elastic vibration sheets. The plurality of vibration sheets are arranged in a circular pattern at the upper end of the support shaft rod, and the outer surfaces of all the vibration sheets can be attached to the inner wall of the exhaust pipe.

[0021] A movable vibration ball is arranged at the center of the plurality of vibration sheets.

[0022] A limiting buckle is arranged on the inner wall of each vibration sheet. All the limiting buckles cooperate to limit the vibration ball.

[0023] Preferably, a spherical head is provided at the upper end of the support shaft rod, and the outer surface of the spherical head abuts against the outer surface of the vibration ball.

[0024] As described above, a Litsea cubeba oil distillation device with an anti-blocking function according to the present invention has the following beneficial effects:

[0025] 1. In the present invention, a liquid separation plate is provided inside the separation cylinder to support the gas-solid separation part, and the outer surface of the gas-solid separation part is attached to the inner wall of the separation cylinder. When the mixture is transmitted into the separation cylinder through the feed pipe, the high-speed moving mixture impacts the gas-solid separation part, causing the gas-solid separation part to rotate and generate a spiral air flow, realizing the separation effect of air flow rising and solid-liquid descending.

[0026] At the same time, the rotating gas-solid separation part will scrape off the substances attached to the inner wall of the separation cylinder, avoiding accumulation and reducing the possibility of blockage. Moreover, when scraping off the attached substances, the rotating gas-solid separation part will throw out the substances impacted and attached to the gas-solid separation part under the action of centrifugal force, avoiding the accumulation of attached substances on the gas-solid separation part.

[0027] 2. In the present invention, a cleaning cutter head is provided at the end of the pneumatic separation blade, and the cleaning cutter head is in a Y shape and attached to the inner wall of the separation cylinder, so that an inclination angle is formed between the end of the cleaning cutter head and the inner wall of the separation cylinder. When the pneumatic separation blade rotates, the cleaning cutter head can more easily scrape off the attached substances on the inner wall of the separation cylinder. The contact point between the end of the cleaning cutter head and the inner wall of the separation cylinder is linear, reducing the friction force.

[0028] 3. In the present invention, the lower end of the exhaust pipe extends into the separation cylinder, and a spoiler with a diameter larger than the inner diameter of the exhaust pipe is provided inside the separation cylinder. When the air flow rises, it will first be blocked by the spoiler and rise along the inner wall of the separation cylinder to the top of the separation cylinder and then turn back into the exhaust pipe, so that the impurities in the gas can preferentially adhere to the inner wall of the separation cylinder, avoiding blockage inside the exhaust pipe.

[0029] 4. In the present invention, a vibration piece is provided at the upper end of the support shaft rod, and a vibration ball is provided inside the vibration piece and limited by a limiting buckle piece. When the air flow rises, it will cause the vibration ball to move irregularly and impact the inner wall of the vibration piece, thereby causing the vibration piece to vibrate. The vibrating vibration piece will cause the air flow to vibrate, and the force generated by the vibration of the air flow will make the attached substances loose and difficult to adhere. Moreover, the vibration of the vibration piece will intermittently impact the inner wall of the exhaust pipe, causing the attached substances inside the exhaust pipe to fall off, achieving the effect of reducing the possibility of blockage of the exhaust pipe.

[0030] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] As Figure 1 - Figure 3 As shown, the present invention provides a Litsea cubeba oil distillation device with an anti-blocking function, including an oil extraction tank 1. The output port of the oil extraction tank 1 is connected to a gas-solid separator 2. The output port of the gas-solid separator 2 is connected to a condenser 3. The output port of the condenser 3 is connected to a cooler 4. The output port of the cooler 4 is connected to a primary oil-water separator 5. The output port of the primary oil-water separator 5 is connected to a secondary oil-water separator 6 to distill and separate Litsea cubeba oil. The Litsea cubeba oil is distilled by heating in the oil extraction tank 1. The gas generated by the distillation is transmitted through a pipeline to the inside of the gas-solid separator 2 for gas-solid separation. The separated Litsea cubeba oil gas enters the condenser 3 and the cooler 4 to be cooled to form liquid Litsea cubeba oil, and finally is separated and purified by the primary oil-water separator 5 and the secondary oil-water separator 6 to obtain Litsea cubeba oil products.

[0045] Specifically, the gas-solid separator 2 includes a separation cylinder 201. A feed pipe 202 is arranged on the side of the separation cylinder 201 and is fluidly connected to the oil extraction tank 1 for transmitting the distilled substance to the inside of the separation cylinder 201. An exhaust pipe 203 is arranged at the top of the separation cylinder 201 and is fluidly connected to the condenser 3. After gas-solid separation, the gaseous substance rises and is discharged from the inside of the separation cylinder 201 through the exhaust pipe 203 and enters the condenser 3 for cooling and condensation to form a liquid. A solid-liquid discharge port 204 is arranged at the bottom of the separation cylinder 201, and the liquid separated inside the separation cylinder 201 is discharged through the solid-liquid discharge port 204.

[0046] Inside the separation cylinder 201, a liquid separation plate 205 and a gas-solid separation part 206 are respectively arranged from bottom to top. The liquid separation plate 205 supports the gas-solid separation part 206, enabling the gas-solid separation part 206 to be rotatable while maintaining a vertical setting. When the substances inside the feed pipe 202 enter the separation cylinder 201, the high-speed moving mixed gas will impact the gas-solid separation part 206. At this time, the liquid will move downward, while the gas will rise under the action of the spiral force. At the same time, the gas-solid separation part 206 is driven to rotate by the mixed gas input by the feed pipe 202. The end of the rotating gas-solid separation part 206 abuts against the inner wall of the separation cylinder 201, thereby cleaning the inner wall of the separation cylinder 201 through the gas-solid separation part 206, and preventing the inner cross-section of the separation cylinder 201 from gradually decreasing until it is blocked due to the increasing attachment.

[0047] As Figure 3 and Figure 4 shown, in some embodiments, the liquid separation plate 205 of the present invention includes a disc plate 2051, which is arranged at a position slightly below the middle inside the separation cylinder 201 and is used to separate the liquid and gas. A support connecting piece 2052 is arranged on the outer surface of the disc plate 2051, and the support connecting piece 2052 is arranged between the side wall of the disc plate 2051 and the inner wall of the separation cylinder 201, so that there is a gap between the side wall of the disc plate 2051 and the inner wall of the separation cylinder 201 for the liquid to flow to the bottom of the separation cylinder 201. A bearing seat 2053 is arranged at the axis of the top of the disc plate 2051, and a bearing is connected to the inside of the bearing seat 2053 by interference fit. The shaft rod of the gas-solid separation part 206 is inserted into the bearing and is connected to the disc plate 2051 through the bearing seat 2053, thereby ensuring that the gas-solid separation part 206 can maintain a vertical setting and can rotate.

[0048] As Figure 4 shown, in some embodiments, the disc plate 2051 of the present invention is an inverted disc shape, so that the liquid can move towards the edge of the disc plate 2051 under the action of gravity and enter the inner bottom of the separation cylinder 201 through the gap between the side wall of the disc plate 2051 and the inner wall of the separation cylinder 201, reducing the accumulation of impurities on the top of the disc plate 2051.

[0049] As Figure 5As shown, in some embodiments, the gas-solid separation part 206 of the present invention includes a support shaft 2061, the lower end of the support shaft 2061 is inserted into the bearing seat 2053, and is connected and supported by the bearing seat 2053. The outer surface of the support shaft 2061 is equidistantly provided with a plurality of pneumatic separation blades 2062 to form a fan blade, and when the pneumatic separation blades 2062 are blown by the airflow, the support shaft 2061 will be driven to rotate. The pneumatic separation blades 2062 overlap the inner wall of the separation cylinder 201, and when the pneumatic separation blades 2062 are rotated, the pneumatic separation blades 2062 will clean the attachments on the inner wall of the separation cylinder 201 under the action of the torsion force. By reducing the attachments on the inner wall of the separation cylinder 201, the blockage of the interior of the separation cylinder 201 is reduced and avoided. At the same time, the attachments attached to the pneumatic separation blades 2062 will be thrown out under the action of the centrifugal force generated when the pneumatic separation blades 2062 rotate.

[0050] like Figure 6 As shown, in some embodiments, a cleaning blade 2063 is provided at one end of the pneumatic separation blade 2062 of the present invention facing the inner wall of the separation cylinder 201, and the cleaning blade 2063 is forked to both sides in a Y shape, and the end of the cleaning blade 2063 is in contact with the inner wall of the separation cylinder 201, and the contacting part is at an inclined angle. The inclined angle is easier to scrape off the attachments on the inner wall of the separation cylinder 201 than the right angle. The contacting part of the cleaning blade 2063 and the separation cylinder 201 is set as a thin blade edge, so that the contact position of the cleaning blade 2063 and the separation cylinder 201 is linear contact, so as to reduce the contact area between the end of the cleaning blade 2063 and the inside of the separation cylinder 201, reduce the frictional force, and reduce the power required for the rotation of the pneumatic separation blade 2062.

[0051] like Figure 3 In some embodiments, the lower end of the exhaust pipe 203 of the present invention extends to the interior of the separation cylinder 201, and there is a gap between the lower end of the exhaust pipe 203 and the inner top of the separation cylinder 201. When the gas rises, the gas will first rise to the inner top of the separation cylinder 201, and then be discharged from the exhaust pipe 203 under the action of pressure. In the process of the gas rising to the inner top of the separation cylinder 201, the impurities in the gas will first adhere to the inner wall of the separation cylinder 201, and flow to the bottom of the separation cylinder 201 under the action of gravity, so as to reduce the impurities from entering the exhaust pipe 203 with a smaller cross-section and causing blockage inside the exhaust pipe 203. At the same time, the interior of the separation cylinder 201 will be pressurized as the gas accumulates, so as to increase the speed of the gas passing through the exhaust pipe 203, reduce the residence time of the gas in the exhaust pipe 203 and the possibility of impurities adhering.

[0052] like Figure 3As shown, in some embodiments, a spoiler 207 is provided between the bottom of the exhaust pipe 203 and the top of the pneumatic separation vane 2062 inside the separation cylinder 201 of the present invention. The axis of the spoiler 207 is penetrated by the support shaft rod 2061 and is used to cooperate with the bearing seat 2053 to further support and limit the support shaft rod 2061, ensuring that the support shaft rod 2061 does not tilt when rotating. There is a gap between the outer surface of the spoiler 207 and the inner wall of the separation cylinder 201. The rising gas enters the upper part of the separation cylinder 201 through the gap and is finally discharged through the exhaust pipe 203. The diameter of the spoiler 207 is larger than the inner diameter of the exhaust pipe 203 and is used to mask the mouth of the exhaust pipe 203, preventing the rising gas from directly entering the exhaust pipe 203. When the gas stays in the separation cylinder 201, it makes it easier for impurities in the gas to adhere to the inner wall of the separation cylinder 201.

[0053] As Figure 3 and Figure 7 shown, in some embodiments, an air vibration part 208 is provided at the end of the support shaft rod 2061 of the present invention. The air vibration part 208 is arranged at the mouth of the lower end of the exhaust pipe 203 and can be driven by the air flow. When the air flow drives the air vibration part 208, the elastic air vibration part 208 will vibrate, thereby driving the gas and the exhaust pipe 203 to vibrate. The vibrating exhaust pipe 203 and gas will make the impurities unstable, making it more difficult for the impurities to adhere to the inner walls of the separation cylinder 201 and the exhaust pipe 203.

[0054] As Figure 7 and Figure 8 shown, in some embodiments, the air vibration part 208 of the present invention includes multiple elastic vibrating pieces 2081. The vibrating pieces 2081 are arranged in a circular pattern at the upper end of the support shaft rod 2061 in a petal shape, so that there is a telescopic space between the vibrating pieces 2081. When the vibrating pieces 2081 are driven by power, the elastic vibrating pieces 2081 will vibrate under the action of the elastic force. And the outer surfaces of all vibrating vibrating pieces 2081 can be attached to the inner wall of the exhaust pipe 203, transmitting the vibration force to the exhaust pipe 203. When the exhaust pipe 203 vibrates, the impurities attached to the inner and outer walls of the exhaust pipe 203 are likely to fall off under the action of the vibration force.

[0055] A movable vibrating ball 2083 is arranged in the center of the petals formed by the multiple vibrating plates 2081. When the rising gas impacts the vibrating ball 2083, the vibrating ball 2083 will float without filtering. The floating vibrating ball 2083 will impact the vibrating plate 2081, thereby driving the vibrating plate 2081 to vibrate. A limiting buckle 2082 is arranged on the inner wall of each vibrating plate 2081. All the limiting buckles 2082 cooperate to limit the vibrating ball 2083 to prevent the vibrating ball 2083 from detaching from the middle of the petals formed by the vibrating plates 2081.

[0056] like Figure 5 and Figure 8 As shown, in some embodiments, the upper end of the support shaft 2061 of the present invention is provided with a spherical head 2064, and the outer surface of the spherical head 2064 contacts the outer surface of the vibration ball 2083 to reduce the contact area between the vibration ball 2083 and the end of the support shaft 2061, so that the airflow can more easily drive the vibration ball 2083 to float. In order to make the floating of the vibration ball 2083 more irregular, a cavity is provided inside the vibration ball 2083 to reduce the weight of the vibration ball 2083, and the cavity is eccentrically arranged. Therefore, during the floating process of the vibration ball 2083, the vibration ball 2083 has an inclination angle when it is suspended due to the center offset, which makes it easier to achieve irregular movement.

[0057] The specific use process of the present invention is as follows:

[0058] The crude oil of Litsea cubeba oil is distilled through the oil extraction tank 1. During the distillation, the Litsea cubeba oil and water vapor enter the separation cylinder 201 through the feed pipe 202. At this time, the steam flowing into the separation cylinder 201 from the feed pipe 202 will hit the surface of the pneumatic separation blade 2062, causing the liquid to flow downward and the gas to rise. At the same time, the airflow will push the pneumatic separation blade 2062 to rotate, thereby cleaning the attachments on the inner wall of the separation cylinder 201. The rising gas will be blocked by the spoiler 207 during the rising process, so that it rises along the wall of the separation cylinder 201 and intersects at the top of the separation cylinder 201. The intersecting gas pressure is gradually squeezed by the subsequent gas, compressed and sunk, and then enters the exhaust pipe 203 for discharge. When the gas enters the exhaust pipe 203, it will push the vibration ball 2083 to float irregularly and hit the vibration plate 2081. The vibration plate 2081 will vibrate when it is hit. The vibration force of the vibration plate 2081 will be transmitted to the gas and the exhaust pipe 203 respectively, so that the gas and the exhaust pipe 203 will resonate and vibrate, making it difficult for impurities in the gas to adhere. The later gas is condensed by the condenser 3 and the cooler 4, and then filtered and separated by the primary oil-water separator 5 and the secondary oil-water separator 6 to form the finished product of the Litsea cubeba oil.

[0059] In summary, for the Litsea cubeba oil distillation equipment with an anti-blocking function of the present invention, a liquid separation plate 205 is arranged inside the separation cylinder 201 to support the gas-solid separation part 206, and the outer surface of the gas-solid separation part 206 is attached to the inner wall of the separation cylinder 201. When the mixture is transmitted into the separation cylinder 201 through the feed pipe 202, the high-speed moving mixture impacts the gas-solid separation part 206, causing the gas-solid separation part 206 to rotate and generate a spiral air flow, achieving the separation effect of air flow rising and solid-liquid descending.

[0060] Meanwhile, the rotating gas-solid separation part 206 will scrape off the substances attached to the inner wall of the separation cylinder 201, avoiding accumulation and reducing the possibility of blockage. Moreover, when scraping off the attached substances, the rotating gas-solid separation part 206 will, under the action of centrifugal force, throw out the substances that impact and adhere to the gas-solid separation part 206, preventing the accumulation of attached substances on the gas-solid separation part 206.

[0061] In the present invention, a cleaning cutter head 2063 is arranged at the end of the pneumatic separation blade 2062, and the cleaning cutter head 2063 is in a Y shape and attached to the inner wall of the separation cylinder 201, so that an inclination angle is formed between the end of the cleaning cutter head 2063 and the inner wall of the separation cylinder 201. When the pneumatic separation blade 2062 rotates, the cleaning cutter head 2063 can more easily scrape off the attached substances on the inner wall of the separation cylinder 201. The contact point between the end of the cleaning cutter head 2063 and the inner wall of the separation cylinder 201 is linear, reducing the friction force.

[0062] In the present invention, the lower end of the exhaust pipe 203 extends into the separation cylinder 201, and a spoiler plate 207 with a diameter larger than the inner diameter of the exhaust pipe 203 is arranged inside the separation cylinder 201. When the air flow rises, it will first be blocked by the spoiler plate 207 and rise along the inner wall of the separation cylinder 201 to the top of the separation cylinder 201 and then turn back into the exhaust pipe 203, enabling the impurities in the gas to preferentially adhere to the inner wall of the separation cylinder 201 and avoiding blockage inside the exhaust pipe 203.

[0063] In the present invention, a vibration piece 2081 is arranged at the upper end of the support shaft rod 2061, and a vibration ball 2083 is arranged inside the vibration piece 2081 and limited by a limit buckle piece 2082. When the air flow rises, it will cause the vibration ball 2083 to move irregularly and impact the inner wall of the vibration piece 2081, thereby causing the vibration piece 2081 to vibrate. The vibrating vibration piece 2081 will cause the air flow to vibrate, and the force generated by the vibration of the air flow will loosen the attached substances and make them difficult to adhere. Moreover, the vibration of the vibration piece 2081 will intermittently impact the inner wall of the exhaust pipe 203, causing the attached substances inside the exhaust pipe 203 to fall off, achieving the effect of reducing the possibility of blockage of the exhaust pipe 203.

[0064] Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0065] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
