Description

Technical Field

[0001] The invention belongs to the technical field of distillation towers, in particular to a turpentine production distillation device. Background Art

[0002] Turpentine is a raw material with multiple uses in medicine and industry. It is generally obtained by steam distilling the rosin liquid exuded from chopped and soaked pine plants.

[0004] Since the turpentine distillation tower is constructed by injecting hot steam into the bottom of the tower to distill the rosin liquid on the oil tower plates, in this type of distillation method, the steam entry point is fixed, and the steam is easy to gather locally, resulting in local over-high temperature. At the same time, the upper and lower oil tower plates are at different distances from the steam entry point, resulting in low distillation temperature at the top and high distillation temperature at the bottom. The above problems will increase the amount of impurities in the produced turpentine.

[0005] In order to solve the above-mentioned problems of fixed steam inlet point and different heating of upper and lower oil tower plates, we propose a turpentine production distillation equipment.

[0039] The specific implementation modes of the present invention are described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific implementation modes.

[0040] Unless explicitly stated otherwise, throughout the specification and claims, the term “comprise” or variations such as “include” or “comprising”, etc., will be understood to include the stated elements or components but not to exclude other elements or components.

[0041] Reference Figure 1-Figure 10 As shown, a turpentine production distillation device of the present invention comprises a distillation tower 1, wherein a steam introduction component 2 for distilling rosin liquid, two oil tray components 3 for holding rosin liquid, and a driving component 4 for driving are arranged inside the distillation tower 1, and steam is introduced into the bottom of the oil tray components 3 respectively so that the rosin liquid on the upper and lower oil tray components 3 are subjected to the same steam temperature, thereby avoiding direct introduction from the bottom, which causes uneven heating of the rosin liquid on the upper and lower oil tray components 3, thereby affecting the turpentine distillation quality;

[0042] The steam inlet assembly 2 includes an outer tube 21 connected to an external steam generator, an inner tube 23 connected to the outer tube 21 at the bottom by a rotary joint 22, a plurality of regularly distributed inlet structures 24 connected to the inner tube 23, and a fixed rod structure 25 located in the lower half and inside the inner tube 23. The inlet structure 24 includes an inlet pipe 241 connected to the inner tube 23 at the inner end and a steam control mechanism 243 located at the inner end of the inlet pipe 241. The steam control mechanism 243 includes a sealing rotating plate 2431, a rotating shaft 2432 that passes through the middle of the sealing rotating plate 2431 from front to back and is rotatably connected thereto, and a top rod 2434 connected to the front side wall of the sealing rotating plate 2431 at the outer end. The inlet pipe 241 is initially arranged horizontally from left to right.

[0043] The inner wall of the inner tube 23 is located at the inner and outer sides of the sealing rotating plate 2431, and sealing pads 244 are respectively provided. The inner wall of the inner tube 23 is located at the inner side of the sealing rotating plate 2431 and is provided with a limit ring 245 near the inner end. The inner end of the push rod 2434 passes through the limit ring 245, and the inner end surface of the push rod 2434 is provided with a convex block 2436. The side wall of the inner tube 23 is located at the outer side of the sealing rotating plate 2431 and is provided with a plurality of regularly distributed steam holes 2411. The side wall of the rotating shaft 2432 is located at the inner part of the sealing rotating plate 2431 and is provided with a spring spring 2433 outside. , by setting a spring spring 2433 to drive the sealing rotating plate 2431 to close, ensuring that there is no gap between the sealing rotating plate 2431 and the sealing pad 244, to prevent steam from overflowing into the outer side of the sealing rotating plate 2431, the fixed rod structure 25 includes a vertical rod 252 whose lower half is located inside the inner tube 23, a fixed rod 251 located at the top of the vertical rod 252 and distributed in a cross shape, and a top block 253 located on the side wall of the vertical rod 252 and corresponding to the position of the inlet pipe 241, and the outer end of the fixed rod 251 is fixed to the inner wall of the distillation tower 1;

[0044] During distillation, steam enters the inner tube 23 through the outer tube 21, and the driving assembly 4 drives the inner tube 23 to rotate reciprocatingly at an angle of 90°. During the rotation of the inner tube 23, the protrusion 2436 will reciprocatingly contact the top block 253. Since the top block 253 is fixed by the fixing rod structure 25, the protrusion 2436 will be pushed outward, and then the sealing rotating plate 2431 will be driven to rotate a certain angle through the protrusion 2436. At this time, the steam can enter the outside of the sealing rotating plate 2431 and be discharged from the steam hole 2411 to perform heating distillation. During the distillation process, the steam hole 2411 will reciprocate to discharge steam outward. At the same time, during the discharge process, the inlet pipe 241 will rotate synchronously. Therefore, during heating, the hot steam will diffuse within a certain range to avoid the continuous introduction of steam at a fixed point, which will cause the resin liquid near the steam discharge point to be overheated and affect the quality.

[0045] The two oil tower plate assemblies 3 are arranged up and down, and the inlet pipe 241 is located below the corresponding oil tower plate assembly 3. The oil tower plate assembly 3 includes a plate portion 31 horizontally arranged on the periphery for holding rosin liquid and a cylinder portion 32 located in the middle of the plate portion 31. It is worth noting that a liquid inlet is provided on the side wall of the tower body 11 above the upper oil tower plate assembly 3 to facilitate the entry of rosin liquid.

[0046] In addition, if Figure 1-Figure 2 As shown, the distillation tower 1 includes a middle tower body 11, a connecting pipe 12 located at the top of the tower body 11 and connected to the condenser, and a water outlet pipe 13 located at the bottom of the tower body 11. A mounting plate 15 is provided in the water outlet pipe 13. The mounting plate 15 is fixed to the inner wall of the water outlet pipe 13 by fixing plates 14 symmetrically arranged on both sides. The driving assembly 4 is installed on the bottom surface of the mounting plate 15. It should be noted that a one-way valve can be provided at the bottom outlet of the water outlet pipe 13 to avoid a small amount of steam overflowing during heating and distillation. This is the prior art of this type of equipment and will not be elaborated here.

[0047] In addition, if Figure 2-Figure 8 As shown, the inner tube 23 is vertically arranged along the central axis of the tower body 11, and a connecting port 231 for steam circulation is provided at a position corresponding to the position of the inlet pipe 241 on the side wall of the inner tube 23. The steam entering the inner tube 23 can enter the inlet pipe 241 from the connecting port 231. The inlet pipe 241 is symmetrically arranged on both sides of the inner tube 23. The innermost end and the outermost end of the steam hole 2411 correspond to the inner edge and the outer edge of the plate portion 31, ensuring that the distribution range of the steam hole 2411 corresponds to the plate portion 31, thereby ensuring that the rosin liquid contained on the oil tower plate assembly 3 can be heated and distilled;

[0048] Specifically, the side wall of the inlet pipe 241 is located on the inner side of the sealing rotating plate 2431 and has an air outlet. A counterweight plate 242 is provided on the air outlet. The outer end of the counterweight plate 242 is hinged to the outer side wall of the air outlet. By providing the counterweight plate 242, when too much steam is introduced in a short time, the excessive steam can lift up the counterweight plate 242, exhaust and reduce pressure, and avoid danger caused by excessive air pressure. In addition, after the sealing rotating plate 2431 is lifted up, when the spring spring 2433 pulls the sealing rotating plate 2431 to close again, if the sealing rotating plate 2431 is closed, Too fast speed may also lead to excessive local air pressure, at which time the counterweight plate 242 will be lifted to exhaust and reduce pressure to ensure safety. The weight of the counterweight plate 242 is less than the elastic force of the clockwork spring 2433, and the rotation angle of the counterweight plate 242 is less than 30°, so as to avoid the counterweight plate 242 rotating too much and being unable to recover. The position of the counterweight plate 242 corresponds to the opening position at the bottom of the cylinder 32, so that the steam overflowing from the counterweight plate 242 enters the cylinder 32, and avoids the accumulated steam discharged from the counterweight plate 242 in a short time from being discharged directly toward the plate 31;

[0049] Furthermore, a scraping structure 26 is staggered above and below the position corresponding to the side wall of the inlet pipe 241 and the oil tower plate assembly 3. The scraping structure 26 includes a connecting rod 261 whose inner end is fixed to the side wall of the inlet pipe 241 and a scraping rod 262 fixed to the outer end of the connecting rod 261. The scraping rod 262 is arranged in a horizontal L shape. A movable groove 3211 is arranged in the cylinder 321. The connecting rod 261 is Z-shaped. The lower horizontal section of the connecting rod 261 is located below the corresponding cylinder 321, and the middle vertical section of the connecting rod 261 extends upward into the movable groove 3211. The top horizontal section of the connecting rod 261 passes through the notch of the movable groove 3211, and the inner side of the scraper rod 262 is respectively in contact with the upper surface of the plate body 311 and the outer wall of the cylinder body 321. When steam is introduced, the inner tube 23 drives the scraper rod 262 to reciprocate synchronously, so that the containing surface of the oil tower plate assembly 3 can be cleaned. Since the rosin liquid has a certain adhesion, the oil tower plate assembly 3 will inevitably have residue after long-term use. If it is not cleaned for a long time, it will not only affect the heat conduction of the oil tower plate assembly 3, but also easily increase the impurities in the rosin liquid and affect the distillation.

[0050] In addition, if Fig. 9 As shown, a side plate 265 is provided on the upper side of the outer end of the scraper rod 262, and a cross bar 264 is provided between the side plate 265 and the outer side wall of the inner vertical section of the scraper rod 262. A disturbance plate 263 is rotatably connected to the cross bar 264, and the cross bar 264 is located at the upper half of the disturbance plate 263. Since the cross bar 264 is located at the upper part of the disturbance plate 263, during the reciprocating rotation, the upper and lower parts of the disturbance plate 263 are subjected to different resistances, causing it to swing left and right synchronously, thereby disturbing the rosin liquid, allowing it to be heated evenly, and reducing impurities in the distilled turpentine oil.

[0051] In addition, if Figure 6 and Figure 7 As shown, the sealing pad 244 is a circular ring plate, the sealing pad 244 located on the inner side of the sealing rotating plate 2431 is fixed at the bottom, and the sealing pad 244 located on the outer side of the sealing rotating plate 2431 is fixed at the top, and the push rod 2434 is hinged to the lower half of the front side wall of the sealing rotating plate 2431 by setting a connector 2435, so as to ensure that when the push rod 2434 is pushed outward, the sealing rotating plate 2431 can only rotate clockwise, and at the same time, under the action of the spring 2433, the sealing pad 244 can be in close contact with the sealing rotating plate 2431 to prevent steam from escaping;

[0052] Specifically, the front and rear ends of the rotating shaft 2432 are fixed to the inner wall of the inlet pipe 241, and the protrusion 2436 and the top block 253 are both triangular in shape and have rounded ends, so that the protrusion 2436 and the top block 253 can have a smooth transition. The two top blocks 253 on the same horizontal plane are set at 90° and form an angle of 45° with the initial inlet pipe 241, wherein the top blocks 253 on the upper and lower sides are staggered and correspond to the positions of the plate portions 31 on the oil tower plate assembly 3 distributed up and down.

[0053] In addition, if Figure 4 As shown, the driving assembly 4 includes a driving motor 41 fixed on the bottom surface of the mounting plate 15, a driving tooth 42 coaxially fixed to the output shaft of the driving motor 41, and a driven tooth 43 meshing with the driving tooth 42. The driven tooth 43 is arranged outside the inner tube 23 and the two are coaxially fixedly connected. The driving motor 41 drives the inner tube 23 to rotate reciprocatingly through the cooperation of the driving tooth 42 and the driven tooth 43.

[0054] In addition, if Fig.10 As shown, the plate portion 31 includes a plate body 311 in a semicircular ring shape, overflow plates 312 located at both ends of the plate body 311, and a control valve 313 located in the middle of the overflow plate 312 for controlling the downward flow of rosin liquid. The upper and lower plate bodies 311 are staggered, and the outer edges of the plate bodies 311 are fixed to the inner wall of the tower body 11. When rosin liquid is added, the rosin liquid will fall on the upper plate body 311 until the liquid level exceeds the overflow plates 312 at both ends, and then fall to the lower staggered plate body 311. After the heating and distillation are completed, the residual liquid can be discharged through the control valve 313.

[0055] Furthermore, the cylinder 32 includes a cylinder 321 located at the center of the plate body 311 and a plurality of baffles 322 arranged in the cylinder 321. The top of the cylinder 321 is sealed, and the counterweight plates 242 are distributed within the bottom opening range of the cylinder 321. The baffles 322 are in the shape of a semicircular plate inclined inward, and a plurality of baffles 322 are staggered. The inner tube 23 passes through the mounting plate 15 and the top surface of the lower cylinder 321 from bottom to top. When the counterweight plate 242 is lifted up, the escaping steam will enter the cylinder 32 and condense into water droplets and fall down under the obstruction of the baffle 322. It is worth noting that the side wall thickness of the cylinder 321 is relatively thick, and the heat conduction efficiency is low, which avoids the concentrated steam from the cylinder 321 to the resin liquid for heat conduction distillation.

[0056] The working principle of the turpentine production distillation equipment of the present invention is specifically as follows:

[0057] At the beginning, rosin liquid is added through the liquid inlet, and the rosin liquid falls on the upper plate body 311 until the liquid level exceeds the overflow plates 312 at both ends, and then falls to the staggered plates 311 below;

[0058] After the feeding is completed, the steam is sent into the inner tube 23 through the outer tube 21 by the steam generator, and at the same time, the driving motor 41 drives the inner tube 23 to rotate reciprocatingly through the active gear 42 and the driven gear 43, and the rotation angle is 90°. During the rotation of the inner tube 23, the protrusion 2436 will reciprocatingly contact the top block 253. Since the top block 253 is fixed by the fixed rod structure 25, the protrusion 2436 will be pushed outward, and then the sealing rotating plate 2431 will be driven to rotate a certain angle through the protrusion 2436. At this time, the steam can enter the outside of the sealing rotating plate 2431 and be discharged from the steam hole 2411 for heating and distillation. During the distillation process, the steam hole 2411 will reciprocate and discharge the steam outward. At the same time, during the discharge process, the inlet pipe 241 will rotate synchronously. Therefore, during heating, the hot steam will diffuse within a certain range to avoid the continuous introduction of steam at a fixed point, which will cause the resin liquid near the steam discharge point to be overheated and affect the quality.

[0059] During the distillation process, when too much steam is introduced in a short period of time, the excess steam can lift up the counterweight plate 242 to exhaust and reduce pressure, thereby avoiding danger caused by excessive air pressure. In addition, when the sealing rotating plate 2431 is lifted up and the spring spring 2433 pulls the sealing rotating plate 2431 to close again, if the sealing rotating plate 2431 closes too quickly, it may also cause excessive local air pressure, and at this time, the counterweight plate 242 will be lifted up to exhaust and reduce pressure to ensure safety.

[0060] After the distillation is finished, the steam generator is turned off, and after the temperature in the distillation tower 1 is cooled down, the control valve 313 is opened to discharge the remaining liquid.

[0061] The foregoing description of specific exemplary embodiments of the present invention is for the purpose of illustration and demonstration. These descriptions are not intended to limit the present invention to the precise form disclosed, and it is clear that many changes and variations can be made based on the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical application, so that those skilled in the art can realize and utilize various different exemplary embodiments of the present invention and various different selections and changes.
