Description

Technical Field

[0001] This invention relates to the field of dissolving pot technology, and more specifically, to a turpentine oil extraction dissolving pot. Background Technology

[0002] Turpentine oil extraction is an important process in the forestry chemical industry. It typically involves placing pine resin raw materials in a dissolving pot, where heating and solvent action dissolve the oil components, separating them from solid impurities such as bark, sawdust, and sediment. For example, patent publication number CN214681070U describes an oil-phase dissolving pot, which includes a base, a dissolving pot body fixedly mounted on the top of the base, a stirring motor mounted on the top of the dissolving pot body, two stirring shafts and a pusher shaft rotatably mounted on the inner wall of the top of the dissolving pot body, the output shaft of the stirring motor connected to the pusher shaft, a driving gear fixedly mounted on the surface of the pusher shaft, driven gears fixedly mounted on the surfaces of both stirring shafts, and both driven gears meshing with the driving gear. Multiple linearly distributed stirring blades are fixedly mounted on both sides of the stirring shaft, and heating blocks are installed inside the stirring blades.

[0003] However, in practical use, the aforementioned dissolving pots typically employ straight-through pipes or ordinary equidistant screw conveyors for slag discharge. Rosin residue often has strong adsorption properties, encapsulating and adsorbing a large amount of high-concentration turpentine solution during discharge. The aforementioned equipment lacks effective solid-liquid separation and compression functions, resulting in extremely high oil content in the residue and a decrease in turpentine yield. Therefore, this application designs a turpentine extraction dissolving pot to further recover the oil contained within the residue during the slag discharge process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a turpentine oil extraction dissolving pot, which solves the problem that existing dissolving pots cannot extract the oil contained in the residue in a timely manner during the slag discharge process, resulting in a decrease in turpentine oil yield.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A turpentine oil extraction and dissolving pot includes a pot body, a support leg on the lower side of the pot body, an extension frame on the upper side of the pot body, a drive motor fixedly installed inside the extension frame, a rotating shaft fixedly installed at the output end of the drive motor, a plurality of stirring rods on the shaft body, the pot body having a jacketed design with a spiral heating channel for heating inside, a fixed bracket fixedly installed on the outer side of the pot body, a slag discharge component for discharging slag fixedly installed inside the fixed bracket, and a drive motor for driving the slag discharge component to discharge slag fixedly installed at one end of the fixed bracket; The slag discharge assembly includes a slag discharge cylinder, which is fixedly installed inside a fixed bracket and one end is connected to the inside of the pot body. A return pipe for oil reflux is provided at the upper end of the slag discharge cylinder. A rotating rod is fixedly installed at the output end of the drive motor. The rotating rod extends through the slag discharge cylinder into the inside of the pot body. The rotating rod is provided with a variable pitch spiral blade for conveying and squeezing the slag. The pitch of the variable pitch spiral blade gradually decreases from the feeding section to the discharge section, which is used to squeeze the slag during the conveying process. The squeezed liquid is discharged through the return pipe, and the squeezed-out slag is discharged from the end of the slag discharge cylinder.

[0006] Preferably, a fixing bracket is fixedly installed on one side of the inner wall of the slag discharge cylinder, and a mating thread is provided on the other side of the inner wall of the slag discharge cylinder. A combination bracket is installed on the inner wall of the slag discharge cylinder through the mating thread. The combined card holder and the fixed card holder are equipped with a support cylinder, which has a hollow design and several wedge-shaped grid strips are provided in the hollow part.

[0007] Preferably, the wedge-shaped grid bars have a wedge-shaped cross-section, the wider end of the wedge-shaped grid bars faces the rotating rod, the surface of the wedge-shaped grid bars is closely attached to the variable pitch spiral blade, and the gap between the wedge-shaped grid bars is narrow on the inside and wide on the outside, forming a V-shaped opening facing outward.

[0008] Preferably, a liquid collection chamber is formed between the combined card holder, the fixed card holder and the support cylinder, and one side of the liquid collection chamber is connected to the return pipe.

[0009] Preferably, the fixed bracket is provided with a guide rail on its upper side, and a movable slide is slidably installed on one side inside the guide rail. A conical back pressure cover is provided at the lower end of the movable slide, and one end of the conical back pressure cover is sealed to the combination card seat. The conical back pressure cover is equipped with a sealed bearing, and the inner side of the sealed bearing is sleeved on the rotating rod body.

[0010] Preferably, a movable bracket is slidably mounted on the other side of the guide rail, and a pressure spring for applying pressure to the conical back cover is installed between the movable bracket and the movable slide.

[0011] Preferably, a set of rotating seats is fixedly installed on one side of the upper surface of the fixed bracket, and an adjusting screw is rotatably installed inside the rotating seat. A knob is fixedly installed at one end of the adjusting screw, and a screw hole is opened at one end of the movable bracket and is threadedly engaged with the adjusting screw.

[0012] Preferably, the pot body is provided with an eccentric guide channel, the lowest point of which is close to the feed section of the slag discharge cylinder.

[0013] Preferably, two circulation ports are provided on one side of the pot body, and the two circulation ports are respectively connected to the inlet and outlet of the spiral heating channel. The outer ends of the two circulation ports are respectively equipped with connecting valves for connecting heating equipment.

[0014] Preferably, a reflux port is provided at one end of the pot body, one end of the reflux port is fixedly connected to the reflux pipe, and a one-way valve is fixedly installed at the other end of the reflux port.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention employs a variable-pitch spiral blade design in the slag discharge assembly, where the pitch gradually decreases from the feeding section to the discharge section. During the conveying process, this compresses the axial space of the slag, forcing the turpentine oil adsorbed inside the slag to be physically squeezed out. Combined with a return pipe, the squeezed oil is returned to the pot, effectively reducing the oil content of the waste slag and increasing the turpentine oil extraction yield.

[0016] 2. By employing wedge-shaped grids as the filter structure, utilizing their "narrow inside and wide outside" characteristic, the squeezed oil can pass through the gaps and be quickly discharged without easily getting stuck. Meanwhile, the slag is squeezed into a filter cake, preventing it from passing through the gaps, thus achieving a filtering effect. At the same time, the spiral blades are tightly fitted to the grids, and through rotation, they act as a scraper, scraping away residual filter cake on the inner wall and ensuring that the filtration channel is unobstructed.

[0017] 3. A mechanism consisting of a pressure spring and a conical back pressure cover is installed at the discharge port of the slag discharge cylinder. The cover can only be opened and discharged when the slag is squeezed to a certain extent and the thrust exceeds the spring threshold. This not only ensures the squeezing effect on the slag and improves the oil extraction rate, but also forms a natural material seal to prevent direct leakage of liquid from the pot.

Detailed Implementation

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 like Figures 1 to 9As shown, a turpentine oil extraction and dissolving pot includes a pot body 1, a support leg 2 on the lower side of the pot body 1, an extension frame 3 on the upper side of the pot body 1, a drive motor 4 fixedly installed inside the extension frame 3, a rotating shaft 5 fixedly installed at the output end of the drive motor 4, a plurality of stirring rods 6 on the shaft of the rotating shaft 5, the pot body 1 is a jacketed design with a spiral heating channel 10 for heating inside, a fixed bracket 8 fixedly installed on the outer side of the pot body 1, a slag discharge assembly 9 for discharging slag fixedly installed inside the fixed bracket 8, and a drive motor 15 for driving the slag discharge assembly 9 to discharge slag fixedly installed at one end of the fixed bracket 8; By starting the drive motor 4 to drive the rotating shaft 5 to rotate, several stirring rods 6 will continuously rotate and stir inside the pot body 1, thereby stirring the turpentine stored inside the pot body 1. With the help of the spiral heating channel 10 to introduce heat, the turpentine is softened, which is conducive to the release of turpentine oil. Thus, the turpentine oil is extracted under the action of stirring. During the extraction process, a lid can be set on the top of the pot body 1.

[0022] The slag discharge assembly 9 includes a slag discharge cylinder 901, which is fixedly installed inside the fixed bracket 8 and one end is connected to the inside of the pot body 1. A return pipe 902 for oil return is provided at the upper end of the slag discharge cylinder 901. A rotating rod 908 is fixedly installed at the output end of the drive motor 15. The rod body of the rotating rod 908 extends through the slag discharge cylinder 901 into the inside of the pot body 1. The rod body of the rotating rod 908 is provided with a variable pitch spiral blade 909 for conveying and squeezing the slag. The pitch of the variable pitch spiral blade 909 gradually decreases from the feeding section to the discharge section, which is used to squeeze the slag during the conveying process. The squeezed liquid is discharged through the return pipe 902, and the squeezed slag is discharged from the end of the slag discharge cylinder 901.

[0023] By starting the drive motor 15, the rotating rod 908 can be driven to rotate, and the variable pitch spiral blade 909 on its rod will rotate accordingly. Since one end of the variable pitch spiral blade 909 is located inside the pot body 1, the turpentine residue after stirring and heating can be rolled into the slag discharge cylinder 901. By gradually reducing the thread pitch of the variable pitch spiral blade 909, the axial space is compressed when the residue is pushed forward, forcing the liquid remaining inside the residue to be physically squeezed out, thus avoiding the impact of residual liquid inside the residue on the turpentine recovery rate.

[0024] Example 2 like Figures 7 to 15 As shown, a fixed bracket 9011 is fixedly installed on one side of the inner wall of the slag discharge cylinder 901, and a mating thread 9015 is provided on the other side of the inner wall of the slag discharge cylinder 901. A combination bracket 9014 is threadedly installed on the inner wall of the slag discharge cylinder 901 through the mating thread 9015. The combination card holder 9014 and the fixed card holder 9011 are equipped with a support cylinder 9012. The support cylinder 9012 has a hollow design and several wedge-shaped grid bars 9013 are set in the hollow part.

[0025] By using threaded mounting for the combination bracket 9014, the combination bracket 9014 can be removed from the slag discharge cylinder 901 during maintenance. Furthermore, the support cylinder 9012 is installed between the combination bracket 9014 and the fixed bracket 9011, allowing the support cylinder 9012 to also be removed. This makes subsequent maintenance of this application more convenient and avoids the accumulation of a small amount of slag inside, which could affect the subsequent slag discharge effect.

[0026] In this embodiment, a plurality of wedge-shaped grid bars 9013 have a wedge-shaped cross section, and the wide end of the plurality of wedge-shaped grid bars 9013 faces the rotating rod 908. The surfaces of the plurality of wedge-shaped grid bars 9013 are closely attached to the variable pitch spiral blade 909, and the gaps between the plurality of wedge-shaped grid bars 9013 are narrow on the inside and wide on the outside, forming a V-shaped opening facing outward.

[0027] Several wedge-shaped grid bars 9013 are welded together with the support cylinder 9012. The gaps between the wedge-shaped grid bars 9013 are set with V-shaped openings facing outwards, so that the turpentine residue will not pass through the gaps after being compressed. The turpentine oil that is squeezed out can pass through the gaps, and the turpentine oil passes through the narrowest part of the gap. The gaps gradually widen to facilitate the direct discharge of turpentine oil. This avoids blockage during the turpentine oil transportation due to the low oil discharge rate. The compression of the turpentine residue prevents the turpentine oil from flowing back into the turpentine residue after being squeezed out, ensuring that no turpentine oil remains inside the residue when it is discharged.

[0028] During the slag conveying and extrusion process, the edge of the variable pitch spiral blade 909 is finely ground, resulting in a very small gap between it and the inner wall of the filter cylinder. When rotating, the variable pitch spiral blade 909 acts as a scraper, continuously scraping off the extruded slag filter cake on the inner surface of the filter cylinder, preventing material accumulation and ensuring the slag discharge rate.

[0029] A liquid collecting chamber 9016 is formed between the combined mounting bracket 9014, the fixed mounting bracket 9011, and the support cylinder 9012. One side of the liquid collecting chamber 9016 is connected to the return pipe 902. A space is reserved at the upper end of the combined mounting bracket 9014, the fixed mounting bracket 9011, and the support cylinder 9012, so that after the combined mounting bracket 9014, the fixed mounting bracket 9011, and the support cylinder 9012 are combined, the space forms the liquid collecting chamber 9016. The liquid collecting chamber 9016 can concentrate the squeezed oil, thereby ensuring that the liquid enters the return pipe 902 at a stable flow rate and improving the stability of the oil return flow.

[0030] Example 3 like Figures 7 to 11As shown, a guide rail 903 is provided on the upper side of the fixed bracket 8, and a movable slide block 907 is slidably installed on one side inside the guide rail 903. A conical back pressure cover 9071 is provided at the lower end of the movable slide block 907, and one end of the conical back pressure cover 9071 is sealed to the combination card seat 9014. A sealed bearing 9072 is installed inside the conical back pressure cover 9071, and the inner side of the sealed bearing 9072 is sleeved on the body of the rotating rod 908.

[0031] It should be noted that a movable bracket 905 is slidably installed on the other side of the guide rail 903, and a pressure spring 906 for applying pressure to the conical back pressure cover 9071 is installed between the movable bracket 905 and the movable slide 907.

[0032] A pressure spring 906 is installed between the movable support 905 and the movable slide 907, so that its pressure is transmitted to the conical back pressure cover 9071. This results in a movable conical plug at the outlet of the slag discharge cylinder 901. The conical back pressure cover 9071 is pressed inward by the pressure spring 906, so that the outlet of the slag discharge cylinder 901 is closed under normal conditions, preventing the slag from being discharged out before it has been squeezed. Under the continuous extrusion and conveying of the variable-pitch spiral vane 909, the conical back pressure cover 9071 will only be opened and the slag discharged when the pressure of the extruded slag pushed by the spiral exceeds the threshold set by the pressure spring 906. This reaction force applied by the pressure spring 906 ensures that the pipe is always kept under high pressure, thereby squeezing the oil drier.

[0033] Among them, a set of rotating seats 904 are fixedly installed on one side of the upper surface of the fixed bracket 8. An adjusting screw 9041 is rotatably installed inside the rotating seat 904. A knob 9042 is fixedly installed at one end of the adjusting screw 9041. A screw hole is opened at one end of the movable bracket 905 and is threadedly engaged with the adjusting screw 9041.

[0034] To meet the needs of different pressures, the adjusting screw 9041 is rotated by turning the knob 9042. Under the limiting sliding of the movable bracket 905 and the guide rail 903, the adjusting screw 9041 is threaded into its screw hole, adjusting the distance between the movable bracket 905 and the movable slide 907, thereby adjusting the pressure applied by the pressure spring 906 to the movable slide 907 to meet the high-pressure extrusion requirements of the slag.

[0035] Example 4 like Figures 1 to 6As shown, an eccentric guide channel 12 is provided inside the pot body 1, with the lowest point of the eccentric guide channel 12 close to the feeding section of the slag discharge cylinder 901. The eccentric guide channel 12 ensures that the loose material after stirring and heating is guided to the feeding section of the slag discharge cylinder 901. Furthermore, since the feeding section of the slag discharge cylinder 901 is equipped with a variable pitch spiral blade 909, the variable pitch spiral blade 909 can actively entrain the material and perform subsequent extrusion operations.

[0036] In the specific setup, two circulation ports 11 are opened on one side of the pot body 1. The two circulation ports 11 are respectively connected to the inlet and outlet of the spiral heating channel 10. The outer ends of the two circulation ports 11 are respectively equipped with connecting valves 7 for connecting heating equipment.

[0037] The heating element is connected to the circulation pipe of the heating equipment via valves 7 at both ends, allowing heat to enter the spiral heating channel 10. This heats the turpentine inside the pot 1, facilitating the extraction of oil from the interior in conjunction with the stirring rod 6. The working principle and method of turpentine heating for oil extraction are conventional or common knowledge and will not be elaborated further here. Those skilled in the art can make any adjustments as needed or for convenience.

[0038] In this embodiment, a reflux port 13 is provided at one end of the pot body 1. One end of the reflux port 13 is fixedly connected to the reflux pipe 902, and a one-way valve 14 is fixedly installed at the other end of the reflux port 13.

[0039] The return pipe 902 can be connected through the return port 13 so that the squeezed oil can flow back into the pot body 1 through the return port 13. The one-way valve 14 can be set to ensure that the returned oil can enter the pot body 1 stably and prevent the liquid inside the pot body 1 from flowing back.

[0040] The working principle of this turpentine oil extraction and dissolving pot: In use, first start the drive motor 4 to rotate the stirring rod 6. Heat is introduced into the jacketed spiral heating channel 10 of the pot body 1 to heat and dissolve the rosin raw material inside the pot. The stirring rod 6 accelerates the dissolving process, separating impurities from the oil; After dissolution is completed or during production, the precipitated bark, sawdust and other impurities slide down the eccentric guide channel 12 at the bottom of the pot to the feed inlet of the slag discharge component 9. Then, the drive motor 15 is started, which drives the rotating rod 908 to rotate. The variable pitch screw 909 conveys the incoming wet slag outward. As the screw pitch gradually decreases, the volume of the slag is continuously compressed during the conveying process, generating a strong internal compressive force.

[0041] Under the pressure of the pressurization, the turpentine contained in the slag will flow out through the gaps in the wedge-shaped grid bars 9013 on the support cylinder 9012 and collect in the liquid collection chamber 9016. The collected liquid will then flow back into the pot body 1 through the return pipe 902 and the one-way valve 14.

[0042] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
