Description

Technical Field

[0001] The utility model belongs to the technical field of oil slurry separation, in particular to a negative pressure fractionation tower for cutting oil slurry. Background Art

[0002] Cutting oil slurry refers to the process of separating oil slurry into different components in the petrochemical process. Cutting oil slurry requires the use of a negative pressure fractionator. A negative pressure fractionator is a tower distillation equipment used in the chemical industry to separate mixtures. It is particularly suitable for distillation operations that need to be performed at lower temperatures. The negative pressure fractionator creates a pressure environment below atmospheric pressure in the tower, thereby lowering the boiling point of the liquid, allowing the components in the mixture to evaporate and condense at a lower temperature. This process utilizes the difference in boiling points of different components in the mixture to achieve separation.

[0003] The prior art discloses some utility model patents in the field of oil-slurry separation technology, among which the utility model patent with application number CN208574241U discloses a tower body, a steam generator, a condenser and a reflux device; the lower part of the tower body is connected to the steam generator; the top of the tower body is connected to one end of the condenser; a liquid accumulation bottom plate is provided on the inner wall of the middle part of the tower body, and a through hole is opened in the middle of the liquid accumulation bottom plate; the edge of the through hole is connected to a riser pipe connected to the through hole and extending to the top of the tower body; a diversion tower plate is provided on the inner wall of the upper part of the tower body; the tower plate includes a tower plate and an overflow weir; the overflow weir is connected to the edge of the tower plate and is perpendicular to the tower plate; the tower plate is provided with a downcomer.

[0004] However, the above method still has the following defects in actual use: although the negative pressure distillation tower can realize the function of heat exchange, it is difficult to separate and process the cutting oil slurry in time when the amount of cutting oil slurry is too much, resulting in difficulty in realizing the heat exchange function, reducing the separation effect of the negative pressure distillation tower, and some cutting oil slurry is prone to insufficient separation.

[0005] Based on this, the utility model designs a negative pressure distillation tower for cutting oil slurry to solve the above problems. Utility Model Content

A negative pressure distillation tower for cutting oil slurry is proposed.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a negative pressure fractionation tower for cutting oil slurry, comprising a base, a fractionation tower body connected to the base, a tower plate connected to the fractionation tower body, an exhaust pipe and a fixed pipe connected to the fractionation tower body, an oil drum and a heat converter connected to the base, a water pump connected to the base, a connecting plate connected to the oil drum, a delivery pipe connected to the outside of the connecting plate, an arc-shaped pipe connected to the delivery pipe, one end of the arc-shaped pipe connected to a discharge pipe, and a cleaning structure connected to the exhaust pipe;

[0028] First embodiment:

[0029] The utility model provides a technical solution: a negative pressure fractionating tower for cutting oil slurry, comprising a base 1, a fractionating tower body 2 is connected to the base 1, a tower plate 17 is connected inside the fractionating tower body 2, an exhaust pipe 3 and a fixed pipe 14 are connected outside the fractionating tower body 2, an oil drum 9 and a heat converter 10 are connected to the base 1, a water pump 11 is connected to the base 1, a connecting plate 6 is connected to the oil drum 9, a delivery pipe 7 is connected outside the connecting plate 6, an arc-shaped pipe 8 is connected to the delivery pipe 7, one end of the arc-shaped pipe 8 is connected to a discharge pipe 15, and a cleaning structure 4 is connected inside the exhaust pipe 3;

[0030] A valve 20 is rotatably connected inside the discharge pipe 15, and a reciprocating structure 5 is connected to the outside of the discharge pipe 15. The reciprocating structure 5 is connected to the valve 20. The reciprocating structure 5 includes an auxiliary plate 501, a tooth plate 502, a gear 503 and a motor 2 504. The output shaft of the motor 2 504 is connected to a rotating plate 505. A protrusion 506 is transmission-connected on the rotating plate 505. A slide groove 507 is provided in the tooth plate 502. The tooth plate 502 is meshed with the gear 503, and the gear 503 is connected to the valve 20.

[0031] Specifically, such as Figure 1-3As shown, the oil cylinder 9 is connected to the heat converter 10 through the connecting plate 6, the fixed pipe 14 is connected to the discharge pipe 15, the tower plate 17 is provided with a through hole 18 and a water outlet 19, one end of the water pump 11 is connected to a connecting pipe 12, the oil cylinder 9 is connected to the heat converter 10 through the connecting pipe 12, the outside of the water pump 11 is connected to a connecting pipe 2 13, the connecting pipe 2 13 is connected to the outside of the base 1, and an exhaust port 16 is provided in the exhaust pipe 3.

[0032] Specifically, such as Figure 5 As shown, the auxiliary plate 501 is connected to the outside of the discharge tube 15 , the tooth plate 502 is slidably connected to the inside of the auxiliary plate 501 , the protrusion 506 is slidably connected to the slide groove 507 , and the motor 2 504 is connected to the auxiliary plate 501 .

[0033] By setting up the auxiliary plate 501, when the tooth plate 502 is affected by the thrust or pull, the tooth plate 502 will slide in the auxiliary plate 501, so that the auxiliary plate 501 plays a certain guiding role in the movement of the tooth plate 502, thereby preventing the tooth plate 502 from getting stuck during movement; by setting up the slide groove 507, when the rotating plate 505 rotates, the upper protrusion 506 will slide in the slide groove 507, so that the slide groove 507 plays a certain auxiliary role in the rotation of the rotating plate 505, and the tooth plate 502 can realize the function of reciprocating movement in the auxiliary plate 501.

[0034] Second embodiment:

[0035] Specifically, such as Figure 4 The cleaning structure 4 includes a fixing ring 401 and a motor 404, a threaded rod 1 402 and a threaded rod 2 403 are rotatably connected inside the fixing ring 401, a cleaning disk 405 is externally threadedly connected to the threaded rod 1 402, the threaded rod 2 403 is connected to the motor 1 404, and the threaded rod 1 402 is externally transmission-connected to the anti-slip belt 406, the cleaning disk 405 is threadedly connected to the outside of the threaded rod 2 403, the threaded rod 1 402 is connected to the threaded rod 2 403 through the anti-slip belt 406, the motor 1 404 is connected to the exhaust pipe 3, the fixing ring 401 is connected inside the exhaust pipe 3, and the cleaning disk 405 is overlapped inside the exhaust pipe 3.

[0036] By setting the anti-slip belt 406, when the motor 1 404 drives the threaded rod 2 403 to rotate, since the threaded rod 2 403 is connected to the threaded rod 1 402 through the anti-slip belt 406, the threaded rod 1 402 and the threaded rod 2 403 can achieve the function of synchronous rotation, thereby ensuring that the cleaning disk 405 can move horizontally; by setting the cleaning disk 405, when the cleaning disk 405 moves to the top of the threaded rod 1 402 and the threaded rod 2 403, the cleaning disk 405 will overlap in the exhaust pipe 3, so that the cleaning disk 405 can play a certain protective role on the top of the inner wall of the exhaust pipe 3, preventing impurities from sticking to the top of the exhaust pipe 3.

[0037] Working principle, when in use: when the cutting oil slurry needs to be separated and processed, the cutting oil slurry in the oil cylinder 9 can be transported to the distillation tower body 2 through the connecting plate 6, the conveying pipe 7 and the arc pipe 8, and the cutting oil slurry will be discharged through the fixed pipe 14 and the discharge pipe 15. During the discharge process, the rotating plate 505 is driven by the motor 2 504 to rotate, and the protrusion 506 will slide in the slide groove 507. The tooth plate 502 will reciprocate in the auxiliary plate 501 as the rotating plate 505 rotates. Since the tooth plate 502 is engaged with the gear 503, the gear 503 will rotate with the movement of the tooth plate 502, and the valve 20 will reciprocate in the discharge pipe 15. The cutting oil slurry can be slowly transported to the distillation tower body 2, and the tower plate 17 will separate the cutting oil slurry through the through hole 18 and the water outlet 19.

[0038] When the gas generated after the cutting oil slurry is separated will be discharged through the exhaust pipe 3. When the inner wall of the exhaust pipe 3 needs to be cleaned, the motor 1 404 drives the threaded rod 2 403 to rotate. Since the threaded rod 2 403 is connected to the threaded rod 1 402 through the anti-slip belt 406, the threaded rod 1 402 and the threaded rod 2 403 can achieve the function of synchronous rotation, and the cleaning disk 405 will slide on the surface of the threaded rod 1 402 and the threaded rod 2 403. After moving, the cleaning disk 405 can clean the inner wall of the exhaust pipe 3, and the cleaned impurities will fall to the bottom of the exhaust pipe 3. Subsequently, the bottom of the exhaust pipe 3 will be disassembled and the scraped impurities will be collected.

[0039] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
