Description

Technical Field

[0001] This utility model relates to the field of distillation pots, specifically a distillation pot for processing rosin. Background Technology

[0002] Rosin is a solid resin acid, a mixture of rosin dissolved in terpenoid liquid, namely turpentine. This mixture has little economic value, so rosin must be processed by distillation to separate the rosin and turpentine, producing rosin and turpentine that meet national quality standards. Rosin and turpentine are important chemical raw materials, used by many industrial sectors. Rosin processing not only provides the country with a large amount of industrial raw materials and export goods, but also improves the living standards of people in mountainous areas and boosts the local economy.

[0003] According to publicly available patent 202022909597.5, a distillation pot for rosin processing includes a pot body, an oil inlet at the upper end of the outer circumference of the pot body, an observation window on the front of the pot body, an oil outlet at the lower end of the outer circumference of the pot body, a motor at the top of the pot body, a filter on one side of the motor, a first connecting pipe on the outer circumference of the filter, a steam engine at one end of the first connecting pipe, a water inlet on the outer circumference of the steam engine, a support foot at the bottom of the steam engine, a second connecting pipe at the center of the bottom of the steam engine, and a heat-conducting oil pipe on the inner surface of the pot body. In the process of realizing this utility model, the inventors discovered that at least the following problems remain unsolved in the prior art, which can be addressed by setting an oil inlet, heat-conducting oil pipe, etc. The hot oil pipes and outlet allow heated heat transfer oil to be transported into the pipes via the inlet. The arrangement of these pipes along the inner wall of the distillation vessel allows for the heating and melting of the rosin within the distillation chamber during processing. This solves the problem of heating the distillation vessel with an open flame. Traditional distillation vessels for rosin processing often rely on manual valves to regulate steam discharge, resulting in slow response, low precision, and an inability to adapt to changes in steam generation rate. Excessive steam discharge can lead to a sudden drop in pressure, while insufficient discharge can result in low distillation efficiency, severely impacting product yield and quality. Furthermore, existing equipment often uses fixed condenser components with unadjustable condensation area, leading to poor versatility and energy efficiency. Therefore, a new technical solution is needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a distillation pot for rosin processing. This solves the technical problems of existing traditional distillation pots for rosin processing, which are prone to problems such as excessively rapid steam discharge leading to a sudden drop in pressure inside the pot, or excessively slow discharge leading to low distillation efficiency, which seriously affects product yield and quality. Moreover, the condensing components of existing equipment are mostly fixed structures, the condensing area cannot be adjusted, and the versatility and energy efficiency are poor.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a distillation pot for processing rosin is designed, including a distillation pot body, a steam exhaust pipe is installed in a continuous manner at the top of the upper cover plate of the distillation pot body, a baffle plate of the same size is sealed and connected inside the steam exhaust pipe, the baffle plate is provided with an arc-shaped groove, an air outlet is opened at the center of the baffle plate, a piston of the same size is movably connected inside the arc-shaped groove of the baffle plate, and an adjustment mechanism is installed on the piston;

[0006] A linkage rod is installed on one side of the adjustment mechanism. The other end of the linkage rod is fixedly connected to one end of the driving plate. The other end of the driving plate is fixedly connected to the outside of the condensing sleeve. Multiple condensing sleeves are provided. A connecting plate is fixedly connected between the multiple condensing sleeves. A condensing extension tube is installed on the other end of the condensing sleeve.

[0007] Preferably, the piston has two sets of vent holes on its periphery, the outer diameter of the piston matches the inner diameter of the steam discharge pipe, and is slidably connected to its inner wall. One end of the linkage rod is fixedly connected to the surface of the piston and slidably connected to the top end of the steam discharge pipe. A sealing sleeve is installed between the linkage rod and the steam discharge pipe.

[0008] Preferably, the adjusting mechanism includes two mounting plates. One end of each mounting plate is fixedly connected to the inner wall of the steam discharge pipe, and the other end of each mounting plate is slidably connected to a guide rod. The other end of the guide rod is fixedly connected to the surface of the piston. A return spring is sleeved on the outside of the guide rod. One end of the return spring abuts against the surface of the piston, and the other end of the return spring abuts against the bottom surface of the mounting plate.

[0009] Preferably, a sealing ring is fixedly connected to the mounting end of the condenser extension tube and the condenser sleeve, and the outer ring of the sealing ring is slidably connected to the inner wall of the condenser sleeve.

[0010] Preferably, the middle of the top of the steam exhaust pipe is connected to one end of the hose, the other end of the hose is sealed to one end of the pipe joint, the other end of the pipe joint is sealed to one end of the condenser sleeve, and the hose, pipe joint and the condenser sleeve are in communication with the inside.

[0011] Preferably, the bottom end of the condensation extension tube is fixedly connected to the surface of the carrier plate, and one end of the carrier plate is fixedly connected to the outer surface of the distillation pot body.

[0012] Preferably, the bottom end of the cover plate is sealed to the inside of the top of the distillation pot body, a stirring motor is fixedly connected to the middle of the upper cover plate, the output end of the stirring motor moves through the inside of the upper cover plate and is fixedly connected to one end of the stirring rod, the stirring rod is located inside the distillation pot body, and a packing cover plate is installed on one side of the stirring motor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The steam generated by heating rosin in this invention's distillation pot is transported outward through a steam exhaust pipe at the top of the cover plate. A baffle plate inside the steam exhaust pipe forms a steam flow channel with a central vent hole via an arc-shaped groove. A piston, movably connected within the groove, slides along it. As the piston moves, it changes the actual opening area of ​​the groove, adjusting the total cross-sectional area of ​​the steam exhaust channel in conjunction with the central vent hole. A larger opening results in more steam being discharged, while a smaller opening results in less steam being discharged. This allows for control of the steam discharge, adapting to the steam release requirements of different stages of rosin distillation, such as preheating, main distillation, and tail distillation. It prevents excessively rapid steam discharge from causing a sudden drop in pressure inside the pot, or excessively slow discharge from affecting distillation efficiency.

[0015] The adjusting mechanism on the piston drives the linkage rod to move linearly. The linkage rod transmits the displacement to the driving plate. Since the driving plate is fixed to the outside of the condensing sleeve, it can drive multiple condensing sleeves connected as a whole by connecting plates to slide synchronously along the condensing extension tube. This adjusts the contact area between the condensing sleeve and the condensing extension tube. When the steam discharge increases, the condensing sleeve increases its contact area with the condensing extension tube, improving the condensing capacity to quickly cool more steam. When the steam discharge decreases, the condensing sleeve reduces its contact area to avoid energy waste. This achieves dynamic matching between steam volume and condensing capacity, ensuring a balance between condensing efficiency and energy saving.

[0016] When the steam pressure inside the distillation pot increases, the steam thrust overcomes the spring force to move the piston, widening the opening of the slot to increase the steam discharge and reduce the pressure inside the pot. When the steam pressure decreases, the spring force pushes the piston back to its original position, narrowing the opening of the slot to reduce the steam discharge and maintain stable pressure inside the pot. Through the dynamic balance between steam pressure and spring force, the piston automatically adjusts, maintaining stable steam discharge and pressure inside the pot without manual intervention.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0025] Example 1: A distillation pot for rosin processing, see [link to example]. Figures 1 to 4 The distillation pot body 1 is included. A steam exhaust pipe 11 is installed at the top of the upper cover plate 27 of the distillation pot body 1. A baffle plate 12 of the same size is sealed inside the steam exhaust pipe 11. The baffle plate 12 is provided with an arc-shaped groove. An air outlet is opened at the center of the baffle plate 12. A piston 13 of the same size is movably connected inside the arc-shaped groove of the baffle plate 12. An adjustment mechanism is installed on the piston 13.

[0026] The steam generated by heating rosin in the distillation pot 1 is transported outward through the steam exhaust pipe 11 at the top of the cover plate. The baffle plate 12 inside the steam exhaust pipe 11 forms a steam flow channel with the central vent hole through an arc-shaped slot. The piston 13, which is movably connected inside the slot, can slide along the slot. When the piston 13 moves, it changes the actual opening area of ​​the slot, which, together with the central vent hole, adjusts the total cross-sectional area of ​​the steam exhaust channel. The larger the slot opening, the more steam is discharged; the smaller the slot opening, the less steam is discharged. This achieves control over the amount of steam discharged, adapting to the steam release requirements of different stages such as rosin distillation preheating, main distillation, and tail distillation, and avoiding a sudden drop in pressure inside the pot due to excessively rapid steam discharge or an excessively slow discharge that affects distillation efficiency.

[0027] A linkage rod 14 is installed on one side of the adjustment mechanism. The other end of the linkage rod 14 is fixedly connected to one end of the drive plate 15. The other end of the drive plate 15 is fixedly connected to the outside of the condenser sleeve 16. Multiple condenser sleeves 16 are provided. A connecting plate 17 is fixedly connected between multiple condenser sleeves 16. A condenser extension pipe 18 is installed on the other end of the condenser sleeve 16. The bottom end of the condenser extension pipe 18 is fixedly connected to the surface of the carrier plate 26. One end of the carrier plate 26 is fixedly connected to the outer surface of the distillation pot body 1. The middle of the top end of the steam exhaust pipe 11 is connected to one end of the hose 24. The other end of the hose 24 is sealed and connected to one end of the pipe joint 25. The other end of the pipe joint 25 is sealed and connected to one end of a condenser sleeve 16. The hose 24, the pipe joint 25 and the condenser sleeve 16 are connected to the inside.

[0028] The adjusting mechanism on piston 13 drives linkage rod 14 to move linearly. Linkage rod 14 transmits displacement to drive plate 15. Drive plate 15, being fixed outside condenser sleeve 16, can drive multiple condenser sleeves 16 connected as a whole by connecting plate 17 to slide synchronously along condenser extension tube 18, thereby adjusting the contact area (i.e., effective condensation area) between condenser sleeve 16 and condenser extension tube 18. When the steam discharge increases (piston 13 expands the slot opening and closing), condenser sleeve 16 synchronously increases the contact area with condenser extension tube 18, improving condensation capacity to quickly cool more steam. When the steam discharge decreases, condenser sleeve 16 reduces the contact area to avoid energy waste, achieving dynamic matching between steam volume and condensation capacity, and ensuring a balance between condensation efficiency and energy saving.

[0029] The top of the steam discharge pipe 11 is connected to the pipe joint 25 via a flexible hose 24. The flexible hose 24 has flexible deformation characteristics and can adaptively adjust its length and angle as the condenser sleeve 16 slides, ensuring that the steam delivery channel is always sealed and unobstructed. After the steam enters the condenser sleeve 16 through the flexible hose 24 and the pipe joint 25, the condenser sleeve 16 exchanges heat with the condenser extension pipe 18 (usually through which a cooling medium is introduced), causing the steam to cool down and condense into liquid products (such as turpentine), thus completing the steam recovery. The carrier plate 26 is fixed on the outer surface of the distillation pot body 1, providing stable support for the condenser extension pipe 18, preventing the condensing components from shifting due to their own weight or vibration, and ensuring the stable operation of the condensation process.

[0030] For details, see Figure 2 One end of the linkage rod 14 is fixedly connected to the surface of the piston 13 and is slidably connected to the top end of the steam discharge pipe 11. A sealing sleeve 31 is installed between the linkage rod 14 and the steam discharge pipe 11.

[0031] One end of the linkage rod 14 is fixed to the surface of the piston 13, and the other end passes through the top of the steam discharge pipe 11 and connects to the drive plate 15, forming a rigid transmission link between the piston 13, the linkage rod 14, and the drive plate 15. This ensures that the displacement of the piston 13 can be transmitted to the condensing sleeve 16 without loss, achieving synchronous action between the two and avoiding lag in condensing regulation due to transmission delay. At the same time, the sealing sleeve 31 between the linkage rod 14 and the steam discharge pipe 11 fills the gap between them, preventing steam from leaking from the gap. This ensures that all steam can enter the condensing system, improving the product recovery rate, and also avoids energy loss or burns to operators caused by high-temperature steam leakage.

[0032] Further, see Figure 2 and Figure 3 The adjustment mechanism includes two mounting plates 2. One end of the two mounting plates 2 is fixedly connected to the inner wall of the steam exhaust pipe 11. The other end of the two mounting plates 2 is slidably connected to a guide rod 21. The other end of the guide rod 21 is fixedly connected to the surface of the piston 13. A return spring 22 is sleeved on the outside of the guide rod 21. One end of the return spring 22 abuts against the surface of the piston 13, and the other end of the return spring 22 abuts against the bottom surface of the mounting plate 2.

[0033] Two mounting plates 2 of the regulating mechanism are fixed to the inner wall of the steam discharge pipe 11, providing vertical sliding support for the guide rod 21. One end of the guide rod 21 is fixed to the piston 13, and the other end slides along the mounting plate 2, restricting the piston 13 to move only along the groove direction, thus preventing the piston 13 from deviating and causing the groove seal to fail or the adjustment to get stuck. The two ends of the return spring 22 outside the guide rod 21 abut against the piston 13 and the mounting plate 2 respectively, forming an elastic balance structure: when the steam pressure in the distillation pot 1 increases, the steam thrust overcomes the spring force to push the piston 13 to move, widening the groove opening to increase the steam discharge and reduce the pressure inside the pot; when the steam pressure decreases, the spring force pushes the piston 13 to return to its original position, narrowing the groove opening to reduce the steam discharge and maintain the pressure inside the pot. Through the dynamic balance between the steam pressure and the spring force, the piston 13 is automatically adjusted, and the steam discharge and the pressure inside the pot can be maintained stably without manual intervention.

[0034] It is worth noting that, see Figure 1 and Figure 4 A sealing ring 23 is fixedly connected to the mounting end of the condenser extension tube 18 and the condenser sleeve 16, and the outer ring of the sealing ring 23 is slidably connected to the inner wall of the condenser sleeve 16.

[0035] The outer ring of the sealing ring 23 at the mounting end of the condenser extension tube 18 and the condenser sleeve 16 is tightly fitted to the inner wall of the condenser sleeve 16. When the condenser sleeve 16 slides along the condenser extension tube 18, the sealing ring 23 always maintains a sealed contact with the inner wall of the sleeve, filling the gap between the two. This design can prevent steam or liquid products from leaking from the joint during the condensation process, avoiding product waste or equipment contamination. At the same time, it ensures that all the steam in the condenser sleeve 16 can exchange heat with the cooling medium, ensuring condensation efficiency and maintaining the sealing and reliability of the condensation system.

[0036] It is worth noting that, see Figure 2 The bottom end of the cover plate is sealed and connected to the inside of the top of the distillation pot body 1. A stirring motor 28 is fixedly connected to the middle of the upper cover plate 27. The output end of the stirring motor 28 moves through the inside of the upper cover plate 27 and is fixedly connected to one end of the stirring rod 29. The stirring rod 29 is located inside the distillation pot body 1. A packing cover plate 3 is installed on one side of the stirring motor 28.

[0037] The bottom end of the cover plate is sealed and connected to the inside of the top of the distillation pot 1, which can isolate the inside of the pot from the outside air, ensuring that the distillation process is carried out in a closed environment, preventing outside air from entering and affecting the purity of the product, while maintaining a stable distillation pressure inside the pot (rosin distillation requires a specific pressure environment to control the boiling point), preventing pressure fluctuations from causing incomplete distillation or a decrease in product quality; the packing cover plate 3 (usually filled with sealing material) on one side of the stirring motor 28 can seal the passage between the motor output shaft and the cover plate, further blocking the steam leakage channel and enhancing the overall sealing of the distillation pot;

[0038] After the stirring motor 28 is started, its output end drives the stirring rod 29 located in the distillation pot 1 to rotate. The stirring rod 29 stirs the rosin in the pot evenly: on the one hand, it can break the static heating layer on the surface of the rosin, so that all areas of the rosin can fully contact the heating source, avoiding local overheating and carbonization or local underheating leading to incomplete distillation; on the other hand, it can accelerate the molecular movement of volatile components in the rosin, promote their escape to form steam, improve steam generation efficiency, shorten the distillation cycle, and ensure the uniformity of rosin distillation and product yield.

[0039] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
