Description

Technical Field

[0001] This invention relates to the field of turpentine oil extraction technology, and more specifically to a slag-steaming pot for extracting turpentine oil from molten slag. Background Technology

[0002] Turpentine oil is an important byproduct obtained during rosin processing, typically coexisting with rosin in rosin raw materials and their processing residues. In rosin production and subsequent processing, the raw materials usually undergo distillation, melting, or dissolution processes to separate turpentine oil and rosin products. After these processes, a certain amount of dissolution residue is often generated, which still contains some turpentine oil that was not separated during the main process.

[0003] In existing technologies, the recovery of turpentine from the dissolved residue typically involves using equipment such as a slag steamer. This involves heating the dissolved residue and introducing steam, causing the residual turpentine to vaporize and be discharged with the steam, then condensed and recovered. However, because the dissolved residue is usually highly viscous and semi-molten, containing a molten rosin phase, it easily forms a continuous covering layer or agglomerates within the slag steamer during heating, thus obstructing the upward flow of steam.

[0004] Under these conditions, steam struggles to penetrate the dissolved slag sufficiently to effectively contact the encapsulated or adsorbed turpentine, resulting in incomplete vaporization of the turpentine and low steam utilization efficiency. Furthermore, existing slag steaming pots often employ continuous stirring or turning to attempt to improve the contact between steam and the dissolved slag. However, continuous stirring tends to cause the highly viscous dissolved slag to form a stable circulating flow or an overall undulating state within the pot, which is actually detrimental to the formation of an effective penetration path for steam within the dissolved slag.

[0005] Therefore, how to break the continuous barrier state of the slag to steam during the processing of high-viscosity, semi-molten slag, and improve the contact efficiency between steam and turpentine in the slag without relying on high-intensity continuous stirring, so as to achieve effective extraction of turpentine from the slag, has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] The purpose of this invention is to provide a slag distillation pot for extracting turpentine oil from molten slag, so as to solve the technical problem of poor contact efficiency between steam and turpentine oil in high-viscosity, semi-molten slag during the distillation process in the prior art.

[0007] The technical problem to be solved by this invention can be achieved through the following technical solution: A slag-steaming pot for extracting turpentine oil from molten slag, comprising: The main body of the slag steaming pot has an installation base at the bottom and a servo motor fixedly connected to the center of the top of the slag steaming pot.

The side end of the support rod is fixedly connected to the scraper handle through the connector. The scraper handle abuts against the side end of the spraying leaf. The side end of the scraper handle is fixedly connected to the scraper blade with a triangular cross-section. The cross-sections of the scraper handle and the scraper blade form an "L"-shaped whole. The scraper blade is in contact with the bottom surface of the spraying leaf.

[0011] As a further aspect of the present invention: the scraper handle has a connecting groove with a triangular cross-section along the height direction.

[0012] As a further embodiment of the present invention: a limiting seat is fixedly connected to the top of the mounting base, and a limiting groove with an arc-shaped cross-section is opened on the top of the limiting seat. A limiting head is rotatably connected to the inner wall of the limiting groove. The diameter of the limiting head is larger than the diameter of the rotating shaft and is fixedly connected to the bottom end of the rotating shaft. A grinding disc is fixedly connected to the outer wall of the limiting head, and the bottom surface of the grinding disc is serrated.

[0013] As a further embodiment of the present invention: a guide platform is provided at the bottom of the steam outlet, the guide platform is located inside the main body of the slag steaming pot, the top and sides of the guide platform are fixedly connected to the inner wall of the main body of the slag steaming pot, the cross-section of the guide platform is inclined towards the steam outlet, a bent flow channel is provided through the guide platform at one end near the feed hole, a heater is installed inside the guide platform, a positioning hole is provided along the axis of the guide platform, the flow channel is connected to the feed hole, and the inner wall of the positioning hole is rotatably connected to the rotating shaft.

[0014] As a further aspect of the present invention: a storage pot is fixedly connected to the side end of the main body of the slag steaming pot via a liquid seal pipe, and a heating ring is fixedly connected to the outer wall of the main body of the slag steaming pot. The horizontal height of the heating ring is higher than the height of the tip of the spraying blade. The liquid seal pipe is connected to the inner cavity of the main body of the slag steaming pot through a steam outlet. The end of the liquid seal pipe away from the steam outlet is connected to the inner cavity of the storage pot. The cross-section of the liquid seal pipe is U-shaped, and the height of the end of the liquid seal pipe near the steam outlet is higher than the height of the end of the liquid seal pipe away from the steam outlet.

[0015] As a further aspect of the present invention: the storage pot is fixedly connected to a filter pot at the end away from the liquid seal pipe via an infusion pipe, the bottom of the storage pot is shaped like a frustum, the two ends of the infusion pipe are respectively connected to the inner cavities of the storage pot and the filter pot, and the infusion pipe is located on top of the frustum shape of the storage pot.

[0016] As a further embodiment of the present invention: the filter pot is fixedly connected to a cleaning pot at the end away from the storage pot via a liquid guide pipe.

The end of the liquid guide pipe away from the filter pot is fixedly connected to the top of the cleaning pot. The cleaning pot has a liquid outlet at the end away from the filter pot.

[0017] The beneficial effects of this invention are: 1. By setting a servo motor to drive the rotating shaft to rotate at a low speed, the rotating shaft drives the conveying blades and the spraying blades to rotate slowly, conveying the molten slag to the steam. The steam is diverted through the steam pipeline and then sprayed out through the connecting pipe and the control head. The molten slag conveyed back and forth comes into direct contact with the steam, changing the contact path between the steam and the molten slag.

[0018] 2. When the molten slag is conveyed by the spray blades, it can fall off from the edge of the spray blades. The falling molten slag increases the contact area with the steam. It should be noted that the steam sprayed from the control head has intervals. When the steam comes into contact with the falling molten slag, the steam can carry the turpentine upward from the intervals, avoiding the obstruction of the turpentine by the continuous covering layer or agglomerates formed by traditional steam.

[0019] 3. As the molten slag is conveyed upward on the spray blades, the amount of molten slag will decrease over time. Under this condition, the molten slag needs to be removed from the spray blades in a timely manner. In this invention, the arc design of the cross-section of the spray blades can promote the removal of molten slag from the surface of the spray blades. If this technical feature is lacking, the time it takes for the molten slag to remove from the surface of the spray blades will increase.

[0020] 4. When the molten slag falls from the top of the spray blades, it will generally fall onto the surface of the next layer of spray blades. The diameter design of the spray blades can increase the contact time between the molten slag and steam. At the same time, the spacing between the spray blades gradually increases, which can increase the path of the molten slag falling. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] like Figures 1-10 As shown, a slag steaming pot for extracting turpentine oil from molten slag includes: a slag steaming pot body 1, a rotating shaft 18, and a steam conveying pipe 2. A mounting base 32 is installed at the bottom of the slag steaming pot body 1. A servo motor 5 is fixedly connected to the center of the top of the slag steaming pot body 1. A feed hole 4 is opened at the top of the slag steaming pot body 1 on the side away from the servo motor 5. A steam outlet 16 is opened at the top of the slag steaming pot body 1 on the side away from the feed hole 4. The top of the rotating shaft 18 passes through the top of the slag steaming pot body 1 and is fixedly connected to the servo motor 5. A conveying blade 19 is fixedly connected to the lower part of the rotating shaft 18. A spraying blade 20 is fixedly connected to the upper part of the shaft 18. The conveying blade 19 and the spraying blade 20 form a continuous whole. The distance between the conveying blade 19 and the spraying blade 20 gradually increases along the height direction of the shaft 18. The arc of the cross section of the spraying blade 20 gradually increases in the direction away from the servo motor 5. The diameter of the spraying blade 20 gradually decreases along the height direction of the shaft 18. The steam pipe 2 is fixedly connected to the outside of the slag pot body 1. Several connecting pipes 23 that penetrate the slag pot body 1 are fixedly connected to the steam pipe 2. A conical control head 22 is fixedly connected to the side end of the connecting pipe 23.

[0026] When the molten slag is added into the slag pot body 1 through the feed hole 4, it collects at the bottom of the slag pot body 1. At this time, the servo motor 5 runs, driving the rotating shaft 18 to rotate at a low speed. The rotating shaft 18 drives the conveying blade 19 and the scattering blade 20 to rotate slowly. The conveying blade 19 conveys the molten slag upward from the bottom of the slag pot body 1. When the molten slag moves to the scattering blade 20 through the conveying blade 19, it begins to separate from the collected molten slag surface. At this time, steam is diverted through the steam pipeline 2 and passes through the connecting pipe 23 through the slag pot body 1, and then the steam enters the slag. Inside the main body 1, steam enters the inner cavity of the slag steaming pot 1 through the control head 22. In the prior art, steam forms a continuous covering layer or agglomerates on the surface of the collected molten slag, while the spray blade 20 transports the molten slag to the steam position. The steam can directly contact the transported molten slag, changing the contact path between the steam and the molten slag. Compared with the traditional method where the steam only contacts the top of the collected molten slag, this method is more direct. In this method, the conveying blade 19 and the spray blade 20 are always in a low-speed rotation state, and the collected molten slag can be continuously transported upward, thereby realizing repeated contact between the molten slag and the steam.

[0027] When the molten slag is conveyed through the spray blades 20, it can fall off from the edges of the spray blades 20. The falling molten slag increases the contact area with the steam. It should be noted that the steam sprayed from the control head 22 has intervals. When the steam comes into contact with the falling molten slag, the steam can carry turpentine upwards from the intervals, avoiding the obstruction of turpentine by the continuous covering layer or agglomerates formed by traditional steam. When the steam is sprayed through the control head 22, the control head 22 can control the steam spray rate. When the molten slag is used to extract turpentine for a long time, the turpentine content in the molten slag will decrease. The control head 22 reduces the amount of steam to avoid excessive use of steam.

[0028] As the molten slag is conveyed upward on the scattering blade 20, the amount of molten slag will decrease over time. Under this condition, the molten slag needs to be removed from the scattering blade 20 in a timely manner. In this invention, the arc design of the cross-section of the scattering blade 20 can promote the removal of molten slag from the surface of the scattering blade 20. If this technical feature is lacking, the time it takes for the molten slag to remove from the surface of the scattering blade 20 will increase.

[0029] When the molten slag falls from the top of the spray blade 20, it will generally fall onto the surface of the next layer of spray blade 20. The diameter design of the spray blade 20 can increase the contact time between the molten slag and steam. At the same time, the spacing of the spray blades 20 gradually increases, which can increase the path of the molten slag falling.

[0030] In some specific implementations, the control head 22 is inclined upwards, and the number of connecting pipes 23 gradually increases along the height of the rotating shaft 18. The opening of the control head 22 is generally aligned with the space between the upper and lower layers of molten slag conveyed by the spraying blade 20. When the molten slag falls, the steam sprayed from the control head 22 can directly contact the molten slag. The amount of molten slag carried by the spraying blade 20 decreases as it rises. Reducing the number of connecting pipes 23 can reduce the cost of using the connecting pipes 23 while ensuring contact between the molten slag and steam. Correspondingly, this reduces the cost of using the control head 22. It should be noted that in the prior art, steam carries turpentine upwards by air pressure. In this invention, the steam flows upwards at an incline, and when it comes into contact with the molten slag, the steam can carry the turpentine upwards.

[0031] In some specific implementations, the spray blade 20 has several sieve holes 21 equidistantly opened along the axis of the main body 1 of the slag pot. Several dividing blades 27 are fixedly connected to the top surface of the spray blade 20, and several scraping components are provided at the bottom of the spray blade 20. The dividing blades 27 are irregularly arranged. The molten slag generally contains impurity particles, which are coated with turpentine. When the molten slag is conveyed through the spray blade 20, the small impurity particles fall through the sieve holes 21. Steam can concentrate the treatment of the large impurity particles. When the molten slag flows off the surface of the spray blade 20, the dividing blades 27 can divide the molten slag to prevent impurities from accumulating and affecting the contact between steam and impurities. Without this technical feature, the accumulated impurities are more fully coated with turpentine, and the irregularly arranged dividing blades 27 can divide the accumulated impurities in multiple directions.

[0032] In this process, when the molten slag falls downward from the sieve hole 21, the amount of molten slag that falls entirely from the edge of the spray blade 20 is reduced, thereby enabling the molten slag to fall in a dispersed manner in space, and allowing steam to pass through the molten slag falling at different positions in sequence.

[0033] In some specific embodiments, the scraping assembly includes: a support rod 24, a scraper 26, and a connector 34. The side end of the support rod 24 is fixedly connected to the inner wall of the slag-steaming pot body 1. The side end of the support rod 24 is fixedly connected to the scraper handle 25 through the connector 34. The scraper handle 25 abuts against the side end of the spraying blade 20. The side end of the scraper handle 25 is fixedly connected to the scraper 26, which has a triangular cross-section. The cross-sections of the scraper handle 25 and the scraper 26 form an "L"-shaped whole. The scraper 26 is in contact with the bottom surface of the spraying blade 20. The scraper handle 25 has a connecting groove 35 with a triangular cross-section along the height direction. The molten slag falls from the surface of the spraying blade 20. During operation, some molten slag will adhere to the edges and bottom of the spray blade 20. This adhered molten slag needs to be treated in time. When the spray blade 20 rotates, the scraper 26 scrapes off the molten slag adhering to the bottom of the spray blade 20, and the scraper handle 25 scrapes off the molten slag adhering to the edges of the spray blade 20. Compared with the scraper handle 25 directly scraping off the molten slag on the edges of the spray blade 20, the connecting groove 35 opened in the scraper handle 25 can guide the falling molten slag. At the same time, the scraper handle 25 becomes two sides that contact the edges of the spray blade 20, which adds an extra side compared to the scraper handle 25 scraping off the molten slag on the edges of the spray blade 20 with only one side.

[0034] Among them, the support rod 24 serves to support the scraping component, and the connector 34 and the scraper 26 are elastic, which can keep the scraping component and the rotating spraying blade 20 in close contact.

[0035] In some specific embodiments, a limiting seat 30 is fixedly connected to the top of the mounting base 32. The limiting seat 30 has a limiting groove 31 with an arc-shaped cross-section on its top. A limiting head 28 is rotatably connected to the inner wall of the limiting groove 31. The diameter of the limiting head 28 is larger than the diameter of the rotating shaft 18 and is fixedly connected to the bottom end of the rotating shaft 18. A grinding disc 29 is fixedly connected to the outer wall of the limiting head 28. The bottom surface of the grinding disc 29 is serrated. When the rotating shaft 18 rotates, the rotating shaft 18 drives the limiting head 28. 8 rotates, and the limiting head 28 rotates along the inner wall of the limiting groove 31. The limiting seat 30 provides a limiting function for the limiting head 28 through the contact between the inner wall of the limiting groove 31 and the limiting head 28, thereby ensuring the stability of the rotation of the bottom of the rotating shaft 18. When the limiting head 28 drives the grinding disc 29 to rotate, the molten slag will enter between the grinding disc 29 and the limiting seat 30. The serrated surface of the grinding disc 29 can grind the molten slag into fine particles.

[0036] In some specific implementations, a guide platform 14 is provided at the bottom of the steam outlet 16. The guide platform 14 is located inside the main body 1 of the slag steaming pot. The top and sides of the guide platform 14 are fixedly connected to the inner wall of the main body 1 of the slag steaming pot. The cross-section of the guide platform 14 is inclined towards the steam outlet 16. A bent guide groove 13 is provided through the guide platform 14 at one end near the feed hole 4. A heater 15 is installed inside the guide platform 14. A positioning hole 33 is provided along the axis of the guide platform 14. The guide groove 13 is connected to the feed hole 4. The inner wall of the positioning hole 33 is rotatably connected to the rotating shaft 18. When the steam carries turpentine to the top of the inner cavity of the slag steaming pot 1, the steam carrying turpentine will condense on the inner wall of the top of the slag steaming pot 1 under this condition. In order to avoid the condensation and backflow of steam and turpentine, the heater 15 installed in the positioning hole 33 is activated. The heat generated by the heater 15 provides heat to the top of the inner cavity of the slag steaming pot 1, thus preventing the condensation of steam carrying turpentine.

[0037] In the prior art, steam carrying turpentine gathers at the top of the inner cavity of the slag pot body 1 and is discharged from the steam outlet 16 by the action of air pressure. The shape of the guide platform 14 can guide the flow of steam carrying turpentine, and the steam carrying turpentine flows directly to the steam outlet 16 for discharge. At the same time, the guide platform 14 reduces the space at the top of the inner cavity of the slag pot body 1, and reduces the space where steam and turpentine gather at the top of the inner cavity of the slag pot body 1.

[0038] When the molten slag is fed into the slag pot body 1 from the feed hole 4, the molten slag tends to adhere to the inner wall of the slag pot body 1. In this invention, the guide channel 13 opened on the guide platform 14 provides guidance for the feeding of the molten slag, increasing the distance between the molten slag and the inner wall of the slag pot body 1. When the molten slag flows out from the guide channel 13, the molten slag falls downward from between the inner wall of the slag pot body 1 and the spraying blade 20. At the same time, the guide platform 14 is attached to the inner wall of the connecting groove 35 through the rotating shaft 18, providing a limit for the top of the rotating shaft 18.

[0039] In some specific implementations, a storage pot 7 is fixedly connected to the side of the main body 1 of the slag steaming pot via a liquid seal pipe 6. A heating ring 3 is fixedly connected to the outer wall of the main body 1 of the slag steaming pot. The horizontal height of the heating ring 3 is higher than the top height of the spraying blade 20. The liquid seal pipe 6 communicates with the inner cavity of the main body 1 of the slag steaming pot via a steam outlet 16. The end of the liquid seal pipe 6 away from the steam outlet 16 communicates with the inner cavity of the storage pot 7. The cross-section of the liquid seal pipe 6 is U-shaped, and the height of the end of the liquid seal pipe 6 near the steam outlet 16 is higher than the height of the end of the liquid seal pipe 6 away from the steam outlet 16. A filter pot 9 is fixedly connected to the end of the storage pot 7 away from the liquid seal pipe 6 via a liquid delivery pipe 8. The bottom of the storage pot 7 is frustum-shaped. The two ends of the liquid delivery pipe 8 are respectively connected to the storage pot. 7 is connected to the inner cavity of the filter pot 9. The infusion pipe 8 is located on top of the frustum-shaped reservoir 7. When steam carrying turpentine enters the reservoir 7 through the liquid seal pipe 6, the reservoir 7 condenses the steam and turpentine and reduces the pressure. The specific working principle is existing technology and will not be elaborated here. After the steam carrying turpentine condenses, it will collect at the bottom of the reservoir 7. The liquid contains impurities and undergoes initial sedimentation. When the liquid level is higher than the infusion pipe 8, the liquid is discharged from the reservoir 7 through the infusion pipe 8. When the liquid enters the filter pot 9, the filter pot 9 cleans the impurities in the liquid again. The specific working principle is existing technology and will not be elaborated here.

[0040] It should be noted that when the molten slag first begins to be steamed in the main body 1 of the slag steaming pot, since there is no liquid in the storage pot 7, a small amount of steam carrying turpentine oil will flow directly out from the inner cavity of the storage pot 7 through the liquid delivery pipe 8, which will cause pressure loss. Therefore, the shape of the liquid seal pipe 6 can be pre-stored or gradually accumulate liquid to buffer the storage pot 7 when it is just starting to operate. The liquid seal pipe 6 designed in this invention automatically forms a liquid seal without the need for additional control structure, avoiding direct steam flow to the liquid delivery pipe 8 and abnormal liquid backflow, and improving the stability and safety of the turpentine oil extraction process. When the steam carrying turpentine oil moves upward to the top of the limiting head 28, the heating ring 3 operates. The heating ring 3 provides heat to the space between the main body 1 of the slag steaming pot and the scraper 25, providing thermal energy for the flow of steam and preventing the steam from condensing during the flow.

[0041] In some specific implementations, a cleaning pot 11 is fixedly connected to the end of the filter pot 9 away from the storage pot 7 via a liquid guide pipe 10. The two ends of the liquid guide pipe 10 are respectively connected to the inner cavities of the filter pot 9 and the cleaning pot 11. The end of the liquid guide pipe 10 away from the filter pot 9 is fixedly connected to the top of the cleaning pot 11. The cleaning pot 11 has a liquid outlet hole 17 at the end away from the filter pot 9. When liquid is discharged from the filter pot 9 through the liquid guide pipe 10, the liquid flows along the liquid guide pipe 10 to the cleaning pot 11. The liquid enters the cleaning pot 11 in the form of droplets. When the liquid collects in the cleaning pot 11, the cleaning pot 11 settles the liquid again. When the liquid level in the inner cavity of the cleaning pot 11 is higher than the liquid outlet hole 17, the liquid will be discharged drop by drop from the liquid outlet hole 17. It should be noted that when the droplets fall from the top of the cleaning pot 11, the droplets will directly merge with the liquid stored in the cleaning pot 11.

[0042] The foregoing has described several embodiments of the present invention in detail, but these embodiments are not limited thereto and should not be considered as limiting the scope of the invention. All equivalent variations and improvements made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
