Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of turpentine processing technology, more particularly, to a cracking system for extracting turpentine from rosin. BACKGROUND

[0002] Turpentine is a kind of essential oil, which is an important industrial raw material. Turpentine is a liquid extracted from rosin by distillation, and the main component is terpene. Turpentine can be mixed with chloroform, diethyl ether or acetic acid in any proportion, but it is not soluble in water. Turpentine is a high flash point flammable liquid with volatility, and a large amount of smoke will be generated during combustion. The material left after rosin is distilled to turpentine is rosin. In the existing turpentine manufacturing process, turpentine cannot be fully distilled from rosin, so that part of the turpentine remains in the rosin, causing the raw material to be wasted.

[0003] The traditional deep processing method of rosin mainly includes the following steps: the turpentine is crushed and then conveyed to a dissolving tank, heated by steam to dissolve, then treated by a high-position pot and a clarifying pot to remove impurities, and finally distilled by a distillation tank to separate rosin and turpentine. The melting process dissolves the rosin and removes most of the impurities. However, the traditional dissolving tank has the problems of uneven heating, poor impurity removal effect, and the separated impurities still containing a large amount of rosin particles, which affects the quality of rosin and reduces the production efficiency. Distillation is the most critical process in the production of rosin, which can affect the product quality and yield of rosin.

In the entire cracking system, the right side of the gas transmission pipe 31 is sequentially connected to an oil-gas separator and a storage tank. The right side of the dissolving tank 3 is connected to multiple sets of high-level pots and clarification tanks, all connected by pipelines. These are not mentioned in the claims and are commonly used equipment in existing cracking systems. See the accompanying drawings for details.

[0031] When rosin needs to be cracked to extract turpentine oil, the operator controls the drive motor 6 to be powered on. After the drive motor 6 is powered on, it drives the synchronous shaft 7 fixedly connected to it to rotate synchronously. The mixing rod 8 on the synchronous shaft 7 rotates accordingly. The operator adds the crushed rosin particles and water and other raw materials into the dissolving tank 3 through the feed pipe 5. The raw materials enter the preheating box 409 and are blocked by multiple sets of hollow guide seats 411, which prolongs the time they are in the preheating box 409. Then the material enters the dissolving tank 3 downwards. Steam is introduced into the dissolving tank 3 through the pipe to heat it to 100 to 105 degrees Celsius, which accelerates the dissolution.

[0032] Multiple mixing rods 8 mix the raw materials. The bottom movable plate 10 lifts the raw materials that are settling at the bottom upwards. As the synchronous shaft 7 rotates, the bottom movable plate 10 flips to the top and moves downwards under the action of gravity. During the movement, it will also impact and push the material to improve the mixing efficiency. After the mixing is completed, the discharge pipe 12 is opened, and impurities will be blocked by the arc-shaped filter plate 11.

[0033] The dissolved fat solution is pressurized into the high-level pot by the steam introduced through the steam tank 1. After staying in the high-level pot for 20 to 40 minutes, the impurities at the bottom of the high-level pot are discharged, and then the fat solution flows into the clarification tank. After clarification, the residue and water are separated to obtain the refined fat solution, which is then transported to the distillation tank 2.

[0034] The user controls the installation motor 14 to rotate, which drives the rotating shaft 24 fixedly connected to it to rotate synchronously. At this time, the electromagnetic ring 25 on the sealing plate 16 is not energized. Due to the frictional force, the sealing plate 16 will not rotate synchronously with the rotating shaft 24. The distribution box 26 will rotate synchronously with the rotating shaft 24. The steam tank 1 fills the distribution box 26 with steam through the steam pipe 28. The ring plate 27 remains stable, so that the inside of the distribution box 26 is sealed. The airflow is evenly sprayed into the inside of the distillation tank 2 through multiple sets of air pipes 29 until the temperature inside the distillation tank 2 reaches between 170 and 180 degrees Celsius.

[0035] The grease entering the distillation tank 2 is stored in the funnel-shaped storage tank 13 and is about to move downward through the overlapping hole 15. The electromagnetic ring 25 works intermittently to generate magnetism. The electromagnetic ring 25 attracts the metal shaft 24, causing the shaft 24 to rotate synchronously and thus causing the sealing plate 16 to rotate. The overlapping hole 27 overlaps with the overlapping hole 15, and the grease moves downward into the overflow tank 19. The push rod 20 is set to work slowly to push the top plate 21 upward. At this time, the grease will move upward and overflow from the overflow tank 19, and move downward through the multi-component flow pipe 22. Currently, the flow pipe 22 is filled with steam. A small amount of grease flows downward along the guide rod 23, thereby increasing the heat exchange area and causing the grease to evaporate quickly. The mixed gas generated by the steam and turpentine will be discharged upward through the gas delivery pipe 31, while the rosin liquid and rosin will be discharged through the bottom delivery pipe 30.

[0036] The above is a general process. This section details the operation process. When the top plate 21 moves up and pushes out a portion of the grease, the steam inside the distribution box 26 has been thrown out into the distillation tank 2. Then the solenoid valve 37 closes, and the steam pipe 28 continues to fill the distribution box 26 with steam, but it is not discharged because it is blocked by the solenoid valve 37. At this time, a small amount of grease flows downward after being divided by the multi-component distribution pipe 22, while the thrown-out steam will enter the distribution pipe 22 to achieve the evaporation mentioned above. The mixed gas produced by the steam and turpentine will be discharged upward through the gas delivery pipe 31, while the rosin liquid and rosin will be discharged through the bottom delivery pipe 30. At this time, the distribution pipe 22 is not completely emptied, and the intermittently working push rod 20 continues to work to push out part of the grease. Then the solenoid valve 37 opens to continue to discharge steam, and this process continues.

[0037] The operator controls the semiconductor cooling chip 407, fan 413, cooler 404 and liquid pump 406 to be powered on. After the liquid pump 406 is powered on, it generates suction to make the coolant inside the storage tank 403 enter the threaded pipe 405, which lowers the heat exchange temperature of the gas delivery pipe 31 and the temperature of the cooling end at the bottom of the semiconductor cooling chip 407, thus lowering the temperature inside the cooling box 401 and further improving the cooling effect. After the mixed gas passes through the cooling box 401, the temperature will drop rapidly, and then it will enter the oil-water separator for separation. Turpentine can then be recovered using the turpentine storage tank.

[0038] The top of the semiconductor cooling chip 407 generates heat, and a large amount of heat is also generated when the cooler 404 and the liquid pump 406 are operating. After the fan 413 inside the mounting base 412 is powered on, it generates suction to discharge the gas inside the annular groove 410, thereby forming a negative pressure that allows the airflow inside the cooling box 401 to enter the annular groove 410 through the return pipe 408, which can achieve the effect of cooling the inside of the cooling box 401. At the same time, the hot flow enters the annular groove 410, causing the temperature of the preheating box 409 to rise. The inner wall of the multiple hollow guide seats 411 contacts the airflow and the temperature rises. At this time, the material entering through the top feed pipe 5 can absorb heat when it is inside the preheating box 409, thereby playing a preheating role.

[0039] In this invention, a storage box 13 is set up to store and block the dissolved grease. With the help of a rotating sealing plate 16, the overlapping holes 15 and 17 intermittently overlap to fill the overflow groove 19 at the bottom. The top plate 21 inside the overflow groove 19 moves slowly to allow a small amount of grease to enter the multi-component flow tube 22. With the help of the guide rod 23, the flow time of the grease can be extended and the heat exchange surface area can be increased. After the steam enters the flow box 26, it will be evenly sprayed into the distillation tank 2 through multiple sets of rotating gas pipes 29, thereby preventing the carbonization of rosin and further increasing the heat exchange area of ​​the grease, thereby improving the distillation efficiency.

[0040] The raw materials are uniformly mixed by multiple sets of mixing rods 8 set inside the dissolving tank 3, and the movable plate 10 used in conjunction with gravity can improve the mixing efficiency. When it is at the bottom, it can lift the material at the bottom to prevent insufficient mixing. When it rotates to the top, the movable plate 10 will be pressed down by gravity, and then the material will be pressed and pushed again.

[0041] The heat generated by the cooling equipment 4 is collected by a heat collection chamber 402 inside the cooling equipment 4, and the heat is input into the preheating box 409 inside the dissolving tank 3. When the material enters the dissolving tank 3, it is blocked by multiple sets of hollow guide seats 411, which makes the material fit with the hollow guide seats 411, increasing the heat exchange area, realizing the preheating of the material, and accelerating the heat dissipation of the cooling equipment 4 to improve the heat dissipation effect.

[0042] Please see Figure 5 The dustproof plate 32 is detachably connected to the inner wall of the mounting base 412, and the dustproof plate 32 is located on the left side of the fan 413.

[0043] In this invention, the dustproof plate 32 can filter dust in the airflow and prevent dust from entering the cooling device 4.

[0044] Please see Figure 6 Among them, a protective sleeve 33 is fixedly connected to the return pipe 408, and the protective sleeve 33 is made of thermal insulation material.

[0045] In this invention, the heat insulation protective sleeve 33 can protect the return pipe 408 and prevent the hot airflow from losing heat and causing waste during the movement.

[0046] Please see Figure 3 Among them, a fan blade 34 is fixedly connected to the rotating shaft 24, and the fan blade 34 is located at the bottom of the distribution box 26.

[0047] In this invention, when the rotating shaft 24 rotates, the fan blades 34 will rotate accordingly. The fan blades 34 generate wind power, which can accelerate the flow of steam and improve the distillation efficiency.

[0048] Please see Figure 1 and 3 Among them, the top of the diversion box 26 is fixedly connected to the guide platform 35, and the front view cross-sectional shape of the guide platform 35 is inclined from top to bottom to both sides.

[0049] In this invention, the guide platform 35 can guide the material discharged from the diversion pipe 22 and prevent the material from being stuck at the top of the diversion box 26 and unable to be discharged.

[0050] Please see Figure 4 Two counterweights 36 are fixedly installed on the movable plate 10. The counterweights 36 are made of metal and are located on the front and back of the mixing rod 8, respectively.

[0051] In this invention, the metal counterweight 36 can raise the mass of the movable plate 10, preventing the movable plate 10 from being unable to move downward due to buoyancy while in the material, thus affecting the mixing efficiency.
