Description

Technical Field

[0001] This invention relates to the field of turpentine production technology, specifically to a turpentine production distillation equipment. Background Technology

[0002] The core process in turpentine production is the distillation and separation of pine resin. Turpentine distillation equipment, as a key piece of equipment in the fields of forest chemical and bio-based product processing, is closely related to other bio-industries in areas such as biomass raw material utilization, bio-based product separation and purification, and green processing technologies. Its technological level directly affects the production efficiency and product quality of bio-based terpenoid products. Turpentine comes from renewable forestry biomass such as pine resin and pine wood, and is a bio-based raw material. Turpentine production falls under the category of forest chemical product manufacturing, and in industry research, it is often categorized under biomanufacturing, biomass chemicals, and other bio-industries. Distillation equipment is crucial for converting pine biomass into bio-based chemicals and is a production tool in the bio-industry. Pre-distillation flocculation and purification are key preliminary steps to ensure distillation efficiency and product quality. Its main function is to remove solid impurities such as sawdust and bark, as well as emulsified water, from the pine resin raw material, preventing impurities from entering the distillation equipment and causing coking and blockage. It also reduces the moisture content of the raw material to decrease distillation energy consumption.

[0003] CN118022361B discloses a distillation device for turpentine production. However, in existing turpentine production, flocculation treatment and material handling before distillation are mostly completed using separate equipment. The mixing of rosin raw materials and powdered flocculants is usually carried out in a separate mixing tank, relying on a single stirring paddle to achieve mixing. This not only results in low mixing efficiency, but also insufficient contact between the flocculant and the raw materials, uneven mixing, and the tendency for local flocculant concentrations to be too high while some raw materials are not fully flocculated. This leads to poor flocculation effect, incomplete removal of impurities and moisture from the raw materials, accelerated equipment wear in subsequent distillation processes, and reduced turpentine yield.

[0010] Preferably, the second feeding mechanism includes a storage box fixedly connected to the top of the pretreatment tank, and the bottom of the storage box is connected to the top of the mounting cover via a first hose.

[0011] Preferably, the extrusion mechanism includes a connecting rod fixedly connected to the bottom of the disc, and an extrusion plate is fixedly connected to the bottom of the connecting rod. The bottom of the extrusion plate is connected to an annular plate through a lifting assembly, and a discharge mechanism is provided at the top of the extrusion plate.

[0012] Preferably, the lifting assembly includes a connecting plate fixedly connected to the side wall of the connecting rod, and the bottom of the connecting plate is connected to the top of the annular plate through a spring telescopic sleeve rod. An adsorption assembly is provided between the connecting plate and the extrusion plate.

[0013] Preferably, the adsorption assembly includes an electromagnet fixedly connected to the bottom of the connecting plate, and an iron block fixedly connected to the top of the annular plate.

[0014] Preferably, the discharge mechanism includes a second flexible tube fixedly inserted into the bottom of the extrusion plate, and a filter screen is fixedly connected to the bottom of the second flexible tube. A pump body is fixedly connected to the top of the pretreatment tank, and the pump body is connected to the upper end of the second flexible tube. The output end of the pump body is connected to a first delivery pipe and a second delivery pipe, and a solenoid valve is provided on the side wall of the first delivery pipe and the second delivery pipe. The first delivery pipe is connected to the distillation equipment, and the second delivery pipe is connected to the water storage tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This type of turpentine oil production distillation equipment, through the installation of a drive mechanism, requires the raw material to be purified before distillation. The main method used is flocculation treatment to remove impurities and water from the raw material. During flocculation, the raw material is fed into the pretreatment tank through the feed pipe, positioned above the disc. Then, it enters the mixing tank through a second circular hole and impacts the top of the inclined plate, driving the rotating disc to rotate. As the disc rotates, it drives the ring to rotate. When the first circular hole aligns with the first flexible tube, the powdered flocculant in the storage tank enters the mixing tank through the first flexible tube and the first circular hole, falling onto the top of the inclined plate. Then, as the disc rotates, when the raw material enters the mixing tank through the second circular hole, it impacts the powdered flocculant on the inclined plate, achieving rapid mixing. This process continues sequentially... The mixture flows through the first and second sector plates and the first and second flow channels, resulting in higher mixing efficiency and better effect. After thorough mixing, it flows out through the L-shaped pipe. When the rotating disk rotates, it drives the L-shaped pipe to rotate as well. Under the action of centrifugal force, the flocculated mixture is thrown against the inner wall of the pretreatment tank, creating an impact effect that further enhances mixing efficiency and effect. Finally, it enters the bottom of the pretreatment tank through the gap between the extrusion plate and the annular plate. At the same time, when the rotating disk rotates, it drives the disc to rotate through the connecting frame, which in turn drives the stirring plate to rotate. When the stirring plate rotates, it not only agitates the raw materials above the disc but also agitates the flocculated mixture at the bottom of the pretreatment tank, thereby improving the flocculation efficiency and effect.

[0016] This type of turpentine oil production distillation equipment, through the installation of an extrusion mechanism, stops the feed pipe from supplying raw materials. At this time, the rotating disc stops rotating. After flocculation is completed, an upper turpentine oil phase, a middle aqueous phase, and a lower impurity layer are formed. Then, an electromagnet is energized, attracting an iron block, which moves the annular plate upward. Simultaneously, the spring telescopic rod is compressed, causing the annular plate to abut against the bottom of the extrusion disc. At this point, the extrusion disc and the annular plate are integrated. Next, the cylinder is activated, moving the lifting ring downward. Simultaneously, the connecting rod moves the extrusion disc and the annular plate downward, causing the annular plate to slide down along the inner wall of the pretreatment tank, scraping and cleaning the inner wall of the pretreatment tank. The extrusion disc slides down along the side wall of the stirring plate, scraping and cleaning the side wall of the stirring plate. When the extrusion disc... When the annular plate contacts the top of the upper turpentine oil phase, the pump is activated to extract the turpentine oil phase. The turpentine oil phase enters the pump body through the second hose and is then transported to the distillation equipment via the first delivery pipe for distillation. Visual sensors detect the liquid levels of each layer. After the turpentine oil phase is extracted, the middle aqueous phase is pumped into a storage tank for collection via the second delivery pipe. When the extrusion plate and annular plate come into contact with the lower impurity layer, they can extrude and recover the entrained oil phase, significantly improving the overall yield. The extruded oil phase is then filtered by a screen and can also enter the distillation equipment for distillation, preventing raw material waste. After extrusion, the cover is opened, and the extruded impurities are discharged and collected through the bottom of the pretreatment tank. This process prevents the impurities from becoming sticky or clumping, making transportation and disposal more convenient. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8 This invention provides a turpentine oil production distillation apparatus, including a pretreatment tank 101 and a cover plate 102 rotatably mounted on the bottom of the pretreatment tank 101. The cover plate 102 rotates via a rotating module driven by a servo motor. A mounting cover 12 is connected to the top of the pretreatment tank 101 via a lifting mechanism, and a rotating disk 13 is rotatably connected inside the mounting cover 12. Multiple mixing tanks 14 are formed on the top of the rotating disk 13, and an L-shaped tube 15 is fixedly inserted into the bottom of each mixing tank 14. A first feeding mechanism is provided on the top of the pretreatment tank 101 for feeding turpentine oil raw materials into the mixing tanks 14. The top of 101 is provided with a second feeding mechanism for feeding powdered flocculant into the mixing tank 14. Each mixing tank 14 is provided with a driving mechanism for driving the rotating disk 13 to rotate. The pretreatment tank 101 is provided with a squeezing mechanism for squeezing the flocculated material. Before distillation, it is convenient to perform flocculation operation on the raw materials, so that the mixing efficiency is higher and the effect is better, thereby improving the efficiency and effect of flocculation. After flocculation is completed, it is convenient to discharge the upper turpentine oil phase, the middle aqueous phase and the lower impurity layer separately. In addition, the lower impurity layer can be squeezed to avoid waste of raw materials and facilitate transportation and disposal.

[0021] Please see Figure 1 and Figure 5The lifting mechanism includes a lifting ring 301 that slides on the inner wall of the pretreatment tank 101, and a bracket 302 is fixedly connected to the top of the pretreatment tank 101. A cylinder 303 is fixedly connected to the top of the bracket 302, and the telescopic end of the cylinder 303 is fixed to the top of the lifting ring 301. A connecting mechanism is provided between the rotating disk 13 and the lifting ring 301. Activating the cylinder 303 can drive the lifting ring 301 to move downward.

[0022] Please see Figure 3 and Figure 4 The connecting mechanism includes a disc 201 rotating within a lifting ring 301, and a connecting frame 203 is fixedly connected between the rotating disc 13 and the disc 201. Multiple stirring plates 202 are inserted into the top of the disc 201. When the rotating disc 13 rotates, it can drive the disc 201 to rotate through the connecting frame 203, thereby driving the stirring plates 202 to rotate. When the stirring plates 202 rotate, they can not only stir the raw materials above the disc 201, but also stir the flocculated mixture at the bottom of the pretreatment tank 101, thereby improving the efficiency and effect of flocculation.

[0023] Please see Figures 5-7 The driving mechanism includes an inclined plate 601 fixedly connected to the side wall of the mixing tank 14, and multiple first sector plates 602 and second sector plates 603 fixedly connected inside the mixing tank 14. A first flow channel 604 is provided between the first sector plates 602 and the mixing tank 14, and a second flow channel 605 is provided between the second sector plates 603 and the mixing tank 14. Before distillation, the raw materials need to be purified, mainly by flocculation treatment, to remove impurities and water from the raw materials. During flocculation treatment, the raw materials are fed into the mixing tank 14 through the first feeding mechanism and impact the top of the inclined plate 601, thereby driving the rotating disk 13 to rotate. When the rotating disk 13 rotates, it drives the ring 404 to rotate, and feeds the powdered flocculant into the mixing tank 14 through the second feeding mechanism, where it falls on the top of the inclined plate 601. Then, as the rotating disk 13 rotates, when the raw material enters the mixing tank 14 through the second round hole 402, it impacts the powdered flocculant on the inclined plate 601, thereby achieving rapid mixing. Then, it flows through the first sector plate 602 and the second sector plate 603 in sequence, and through the first flow channel 604 and the second flow channel 605, thereby making the mixing efficiency higher and the effect better. After being fully mixed, it flows out through the L-shaped pipe 15.

[0024] Please see Figure 2 , Figure 4 , Figure 5 and Figure 7The first feeding mechanism includes a ring 404 fixedly connected to the top of the rotating disk 13. The top of the ring 404 is rotatably connected to the top of the mounting cover 12. A sealing gasket is provided on the top of the ring 404, and multiple arrayed first circular holes 401 are opened on the top of the ring 404. A second circular hole 402 is opened on the top of the mounting cover 12. The top of the pretreatment tank 101 is connected to a feed pipe 403. The raw material is fed into the pretreatment tank 101 through the feed pipe 403 and is positioned above the rotating disk 201. Then, it enters the mixing tank 14 through the second circular hole 402 and impacts the top of the inclined plate 601, thereby driving the rotating disk 13 to rotate. When the rotating disk 13 rotates, it can drive the ring 404 to rotate.

[0025] Please see Figure 2 and Figure 4 The second feeding mechanism includes a storage box 502 fixedly connected to the top of the pretreatment tank 101, and the bottom of the storage box 502 is connected to the top of the mounting cover 12 through the first hose 501. When the first round hole 401 is aligned with the first hose 501, the powdered flocculant in the storage box 502 can enter the mixing tank 14 through the first hose 501 and the first round hole 401 and fall on the top of the inclined plate 601. Then, as the rotating disk 13 rotates, when the raw material enters the mixing tank 14 through the second round hole 402, it can impact the powdered flocculant on the inclined plate 601, thereby enabling rapid mixing. Then, it flows through the first sector plate 602 and the second sector plate 603 in sequence, and through the first flow channel 604 and the second flow channel 605, thereby making the mixing efficiency higher and the effect better.

[0026] Please see Figure 4 and Figure 8 The extrusion mechanism includes a connecting rod 701 fixedly connected to the bottom of the disc 201, and an extrusion disc 702 fixedly connected to the bottom of the connecting rod 701. An annular plate 703 is connected to the bottom of the extrusion disc 702 via a lifting assembly, and a discharge mechanism is provided at the top of the extrusion disc 702. This stops the feed pipe 403 from feeding raw materials. At this time, the rotating disc 13 stops rotating. After flocculation is completed, an upper turpentine oil phase, a middle aqueous phase, and a lower impurity layer are formed. Then, the lifting assembly drives the annular plate 703 to move upwards and abut against the bottom of the extrusion disc 702. At this time, it is possible to... The extrusion disc 702 and the annular plate 703 are integrated. Then, the cylinder 303 is activated, which drives the lifting ring 301 to move downward. At the same time, the connecting rod 701 drives the extrusion disc 702 and the annular plate 703 to move downward, so that the annular plate 703 slides down along the inner wall of the pretreatment tank 101, which can scrape and clean the inner wall of the pretreatment tank 101. The extrusion disc 702 slides down along the side wall of the stirring plate 202, which can scrape and clean the side wall of the stirring plate 202. The upper turpentine oil phase and the middle water phase are discharged sequentially through the discharge mechanism.

[0027] Please see Figure 8 The lifting assembly includes a connecting plate 801 fixedly connected to the side wall of the connecting rod 701, and the bottom of the connecting plate 801 is connected to the top of the annular plate 703 through a spring telescopic sleeve 802. An adsorption assembly is provided between the connecting plate 801 and the extrusion plate 702. The annular plate 703 is adsorbed by the adsorption mechanism, so that it moves upward and abuts against the bottom of the extrusion plate 702. At the same time, the spring telescopic sleeve 802 is compressed.

[0028] Please see Figure 8 The adsorption assembly includes an electromagnet 901 fixedly connected to the bottom of the connecting plate 801, and an iron block 902 fixedly connected to the top of the annular plate 703. When the electromagnet 901 is energized, it attracts the iron block 902, which can drive the annular plate 703 to move upward.

[0029] Please see Figure 2 , Figure 4 and Figure 6 The discharge mechanism includes a second flexible hose 1002 fixedly inserted at the bottom of the extrusion plate 702, with a filter screen 1003 fixedly connected to the bottom of the second flexible hose 1002. A pump body 1001 is fixedly connected to the top of the pretreatment tank 101, and the pump body 1001 is connected to the upper end of the second flexible hose 1002. The output end of the pump body 1001 is connected to a first delivery pipe and a second delivery pipe, and solenoid valves are installed on the side walls of the first and second delivery pipes. The first delivery pipe is connected to the distillation equipment, and the second delivery pipe is connected to the water storage tank. When the extrusion plate 702 and the annular plate 703 contact the top of the liquid surface of the upper turpentine phase, a visual sensor is installed on the side wall of the pretreatment tank 101 to facilitate the detection of the phase interfaces. The pump body 1001 is then activated to extract the turpentine phase. The turpentine oil phase enters the pump body 1001 through the second hose 1002 and is then transported to the distillation equipment through the first conveying pipe for distillation. The liquid levels of each layer are detected by a visual sensor. After the turpentine oil phase is extracted, the middle aqueous phase is pumped into the water storage tank for collection through the second conveying pipe. When the extrusion plate 702 and the annular plate 703 come into contact with the lower impurity layer, they can be extruded. Extrusion can squeeze out and recover the entrained oil phase, significantly improving the total yield. Under the filtering effect of the filter screen 1003, the extruded oil phase can also enter the distillation equipment for distillation, avoiding raw material waste. After extrusion, the cover plate 102 is opened, and the extruded impurities can be discharged and collected through the bottom of the pretreatment tank 101. They are not easy to stick or clump, making transportation and disposal more convenient.

[0030] Working principle: Before distillation, the raw materials need to be purified, mainly by flocculation treatment to remove impurities and water. During flocculation treatment, the raw materials are fed into the pretreatment tank 101 through the feed pipe 403 and placed above the disc 201. Then, they enter the mixing tank 14 through the second round hole 402 and impact the top of the inclined plate 601, thereby driving the rotating disc 13 to rotate. When the rotating disc 13 rotates, it drives the ring 404 to rotate. When the first round hole 401 is aligned with the first hose 501, the powdered flocculant in the storage tank 502 can enter the mixing tank 14 through the first hose 501 and the first round hole 401 and fall onto the top of the inclined plate 601.

[0031] Next, as the rotating disk 13 rotates, when the raw material enters the mixing tank 14 through the second round hole 402, it impacts the powdered flocculant on the inclined plate 601, thus achieving rapid mixing. Then, it flows sequentially through the first sector plate 602 and the second sector plate 603, and through the first flow channel 604 and the second flow channel 605, thereby making the mixing efficiency higher and the effect better. After being fully mixed, it flows out through the L-shaped pipe 15. Furthermore, when the rotating disk 13 rotates, it can drive the L-shaped pipe 15 to rotate. Under the action of centrifugal force, the flocculated mixture can be thrown towards the inner wall of the pretreatment tank 101, forming an impact effect again, making the mixing efficiency higher and the effect better.

[0032] Then, the material enters the bottom of the pretreatment tank 101 through the gap between the extrusion plate 702 and the annular plate 703. At the same time, when the rotating plate 13 rotates, it can drive the disc 201 to rotate through the connecting frame 203, thereby driving the stirring plate 202 to rotate. When the stirring plate 202 rotates, it can not only stir the raw material above the disc 201, but also stir the flocculated mixture at the bottom of the pretreatment tank 101, which can improve the efficiency and effect of flocculation.

[0033] Finally, the feed pipe 403 is stopped from feeding raw materials. At this time, the rotating disk 13 stops rotating. After flocculation is completed, an upper turpentine oil phase, a middle water phase, and a lower impurity layer are formed. Then, the electromagnet 901 is energized. After the electromagnet 901 is energized, it attracts the iron block 902, which can drive the annular plate 703 to move upward. At the same time, the spring telescopic sleeve 802 is compressed, and the annular plate 703 is pressed against the bottom of the extrusion disk 702. At this time, the extrusion disk 702 and the annular plate 703 can be formed into a whole.

[0034] Next, the cylinder 303 is activated, which drives the lifting ring 301 to move downward. At the same time, the connecting rod 701 drives the extrusion plate 702 and the annular plate 703 to move downward, so that the annular plate 703 slides down along the inner wall of the pretreatment tank 101, which can scrape and clean the inner wall of the pretreatment tank 101. The extrusion plate 702 slides down along the side wall of the stirring plate 202, which can scrape and clean the side wall of the stirring plate 202. When the extrusion plate 702 and the annular plate 703 come into contact with the top of the liquid surface of the upper turpentine phase, the pump body 1001 is activated, which can extract the turpentine phase. The turpentine phase enters the pump body 1001 through the second hose 1002 and is then transported to the distillation equipment through the first conveying pipe for distillation operation. The liquid surface of each layer is detected by the vision sensor.

[0035] After the turpentine oil phase is extracted, the middle aqueous phase is pumped into the water storage tank for collection through the second conveying pipe. When the extrusion plate 702 and the annular plate 703 come into contact with the lower impurity layer, they can be extruded. Extrusion can squeeze out and recover the entrained oil phase, significantly improving the total yield. Under the filtration of the filter screen 1003, the extruded oil phase can also enter the distillation equipment for distillation, avoiding waste of raw materials. After extrusion, the cover plate 102 is opened, and the extruded impurities can be discharged and collected through the bottom of the pretreatment tank 101. They are not easy to stick or clump, making transportation and disposal more convenient.
