Description

Technical Field

[0001] The utility model relates to the technical field of rosin refining, in particular to a device for rosin distillation. Background Art

[0002] During the rosin refining process, distillation is one of the key steps to extract high-purity rosin. Traditional high-temperature distillation methods often face some technical problems. For example, existing distillation systems usually directly connect the distillation pot to the condenser tube without an effective buffer device. Therefore, during high-temperature vacuum distillation, the rosin liquid material boils rapidly when heated, and the generated steam contains a large number of unvaporized liquid particles that directly enter the condenser tube. These particles are prone to form particle deposits during the condensation process, which not only affects the condensation efficiency but also causes impurities to mix into the refined rosin, resulting in a darker color and unstable color of the product. Therefore, in order to improve the stability of the rosin refining process and the product quality, it is particularly important to design a new type of distillation device. Summary of the Invention

[0003] The utility model provides a rosin distillation device with an efficient buffering function. This distillation device can play a buffering role during the high-temperature distillation of refined rosin, preventing the rosin liquid material from boiling at high temperature and directly entering the condenser tube for cooling during vacuum distillation. Thus, it ensures that the steam entering the condenser tube is a pure substance such as rosin resin acid, thereby solving the problems existing in the above-mentioned existing distillation system.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is:

[0005] It includes a distillation pot and a storage tank. A condenser tube is provided between the distillation pot and the storage tank. One end of the condenser tube is connected to the distillation pot, and the other end of the condenser tube is connected to the storage tank. A baffle is provided at the connection between the distillation pot and the condenser tube, and the main body of the baffle is designed in a mesh shape.

[0006] In the above technical solution, a more specific technical solution can also be: The baffle is provided with multiple inverted V-shaped undulating grooves on the mesh structure.

[0007] Further, the width of the mesh holes of the baffle is 4 mm.

[0008] Further, the spacing between the mesh holes of the baffle is 2 mm.

[0009] Further, the condenser tube is provided with a water inlet and a water outlet. The water inlet is close to the distillation pot, and the water inlet opens downward; the water outlet is close to the storage tank, and the water outlet opens upward.

[0010] Further, a sealing member is provided at the connection between the baffle and the distillation pot and the condenser tube.

[0011] Furthermore, the condenser tube is inclined between the distillation pot and the storage tank, with the end close to the distillation pot at a higher position and the other end gradually decreasing until it approaches the storage tank.

[0012] Due to the adoption of the above technical solutions, the present utility model has the following beneficial effects compared with the prior art:

[0013] 1. By installing a baffle at the connection port between the distillation pot and the condenser tube, the main function of the baffle is to play a buffering role during the high-temperature distillation of refined rosin, preventing the rosin liquid material from boiling directly into the condenser tube for cooling during vacuum distillation, ensuring that the steam of pure rosin resin acid and other components enters the condenser tube, thus solving the problems of deep color and unstable color of the refined rosin product in the existing distillation system, and then significantly improving the stability of the rosin refining process and the product quality, providing strong support for the technological progress and industrial upgrading of the rosin production industry.

[0014] 2. Specifically, the functions of the baffle of the present utility model include:

[0015] 2.1 Buffering function: The baffle can slow down the speed of the high-temperature rosin liquid material entering the condenser tube, forming a relatively stable steam layer behind the baffle. In this way, only the completely vaporized steam can pass through the baffle and enter the condenser tube, effectively avoiding the entrainment of liquid particles.

[0016] 2.2 Improving distillation efficiency: Through the buffering function of the baffle, the flow of steam between the distillation pot and the condenser tube is smoother, reducing the turbulence and eddy current phenomena of the steam, and improving the condensation efficiency of the steam.

[0017] 2.3 Improving product quality: Since mainly pure steam enters the condenser tube, avoiding the mixing of liquid particles, the intermediate fraction distilled is high-purity refined rosin with a light color and stable color.

[0018] 2.4 Extending the service life of the equipment: The baffle can also reduce the direct impact of the steam on the condenser tube, reducing the wear and corrosion of the condenser tube, and thus extending the service life of the equipment.

[0019] 3. The main body of the baffle of the present utility model is designed as a planar mesh, with evenly arranged mesh holes, which can not only ensure the smooth passage of steam but also effectively block large-particle liquid particles.

[0020] 4. Multiple inverted V-shaped undulating grooves are processed on the mesh structure of the baffle of the present utility model. These grooves are distributed along the steam flow direction, forming a series of "barriers", which can slow down the steam flow rate, cause the steam to form eddy currents between the grooves, thereby increasing the contact time between the steam and the baffle, and facilitating the deposition of the liquid particles entrained in the steam at the bottom of the grooves under the action of gravity.

[0021] 5. The utility model is provided with a sealing member at the connection between the baffle plate, the distillation pot and the condenser tube, ensuring good sealing performance and preventing steam leakage.

[0022] 6. The condenser tube of the utility model is inclined and arranged between the distillation pot and the storage tank. Such a design has the following several remarkable advantages:

[0023] 6.1 Improving the condensation efficiency: The inclined design of the condenser tube helps the steam to form a longer condensation path inside the tube. Since the steam flows from a higher place to a lower place, it will have a longer contact time with the inner wall of the condenser tube, thus improving the condensation efficiency. This means that more steam can be condensed into liquid before entering the storage tank, reducing the direct inhalation of rosin steam into the vacuum pump for discharge, and improving the resource utilization rate and product yield;

[0024] 6.2 Reducing the accumulation of condensate: The inclined design also helps to reduce the accumulation of condensate inside the tube. When the steam condenses into liquid inside the condenser tube, these liquids will flow along the inclined tube wall to the lower end and are finally discharged or collected; this can avoid the accumulation of condensate inside the tube and reduce the obstruction to the steam flow;

[0025] 6.3 Preventing backflow: During the distillation process, if the condenser tube is not properly designed, the situation where the condensate flows back into the distillation pot may occur, which will affect the distillation effect and product quality; the inclined design can ensure the smooth discharge of the condensate and avoid the occurrence of backflow phenomenon, thus ensuring the stability of the distillation process and product quality;

[0026] 6.4 Adapting to vacuum distillation: During the vacuum distillation process, due to the reduction of the system pressure, the boiling point of the steam will also decrease accordingly. The inclined condenser tube can better adapt to this change and ensure that the steam can still be fully condensed under reduced pressure conditions, thus improving the efficiency and effect of vacuum distillation;

[0027] 6.5 Simplifying maintenance and cleaning: The inclined design also simplifies the maintenance and cleaning work of the condenser tube. Since the condensate can be discharged smoothly, reducing the liquid accumulation and dirt inside the tube, the difficulty and frequency of cleaning are thus reduced; at the same time, the inclined pipeline is also easier for visual inspection and troubleshooting;

[0028] 6.6 In summary, the condenser tube is designed to be inclined and located between the distillation pot and the storage tank, having the advantages of improving the condensation efficiency, reducing the accumulation of condensate, preventing backflow, adapting to vacuum distillation, and simplifying maintenance and cleaning. These advantages together improve the overall performance of the distillation process and product quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present utility model will be further described in detail below with reference to the accompanying drawings:

[0035] Such as Figure 1 A rosin distillation device with an efficient buffering effect as shown, which includes a distillation pot 1 and a storage tank 2. A condenser tube 3 is provided between the distillation pot 1 and the storage tank 2. One end of the condenser tube 3 is connected to the top of the distillation pot 1, and the other end of the condenser tube 3 is connected to the top of the storage tank 2. A baffle 4 is provided at the connection between the distillation pot 1 and the condenser tube 3. The functions of the baffle here include: (1) buffering effect: The baffle 4 can slow down the speed of the high - temperature rosin liquid material entering the condenser tube 3, so that a relatively stable steam layer is formed behind the baffle 4. In this way, only the completely vaporized steam can pass through the baffle 4 and enter the condenser tube 3, effectively avoiding the entrainment of liquid particles; (2) improving the distillation efficiency: Through the buffering effect of the baffle 4, the flow of steam between the distillation pot 1 and the condenser tube 3 is more stable, reducing the turbulence and eddy current phenomena of the steam, and improving the condensation efficiency of the steam; (3) improving the product quality: Since the main component entering the condenser tube 3 is pure steam, avoiding the mixing of liquid particles, the intermediate fraction distilled out is high - purity refined rosin, with a light product color and stable color; (4) extending the equipment life: The baffle 4 can also reduce the direct impact of steam on the condenser tube 3, reducing the wear and corrosion of the condenser tube 3, thereby extending the service life of the equipment.

[0036] The main body of the baffle 4 is designed in a mesh shape, and its mesh holes are evenly arranged. Such a setting can not only ensure the smooth passage of steam but also effectively block large - particle liquid particles.

[0037] The main material of the baffle can be selected as stainless steel (such as 316L stainless steel) because it has excellent high - temperature resistance and corrosion resistance, which is suitable for use in the distillation process.

[0038] The baffle 4 is provided with a plurality of inverted V-shaped undulating grooves 4-1 on the mesh structure. These grooves 4-1 are distributed along the steam flow direction, forming a series of "barriers". With such a setting, the steam flow rate can be slowed down, causing the steam to form vortices between the grooves 4-1, thereby increasing the contact time between the steam and the baffle 4, which is beneficial for the liquid particles entrained in the steam to deposit at the bottom of the grooves 4-1 under the action of gravity. The depth and width of the grooves 4-1 need to be adjusted according to the steam flow rate and the amount of liquid particles to be blocked to achieve the best effect.

[0039] The width of the mesh holes 4-2 of the baffle 4 is 4 mm, and the spacing between the mesh holes 4-2 is 2 mm. With such a setting, it can ensure that impurities can be blocked while reducing the steam flow resistance.

[0040] The condensate pipe 3 is provided with a water inlet 3-1 and a water outlet 3-2. The water inlet 3-1 is close to the distillation pot 1, and the opening of the water inlet 3-1 faces downward; the water outlet 3-2 is close to the storage tank 2, and the opening of the water outlet 3-2 faces upward.

[0041] A seal 5 is provided at the connection between the baffle 4 and the distillation pot 1 and the condensate pipe 3. The seal 5 can be a high-temperature resistant gasket or an O-ring, or other seals. With such a setting, it can ensure good sealing at the connection and prevent steam leakage.

[0042] The condensate pipe 3 is inclined between the distillation pot 1 and the storage tank 2, and the end close to the distillation pot 1 is at a higher position, while the other end gradually decreases until it approaches the storage tank 2. With such a setting, it has the advantages of improving the condensation efficiency, reducing the accumulation of condensate water, preventing backflow, adapting to vacuum distillation, and simplifying maintenance and cleaning. These advantages together improve the overall performance and product quality of the distillation process.
