Description

Technical Field

[0001] This utility model relates to the field of fractionation equipment technology, specifically to a fractionation equipment for processing non-finished petroleum products. Background Technology

[0002] Petroleum is a complex mixture of multiple components. Whether for research or processing, petroleum must be fractionated. Through fractionation, petroleum can be separated into different components, such as gasoline, diesel, kerosene, paraffin wax, and asphalt, which have different uses and values.

[0003] Existing patent application number: CN202221728147.9 A fractionation device in the production process of non-finished oil petroleum products, including a fractionation device body and a heating evaporation box. A gas guide pipe, a return pipe and an outlet pipe are fixedly connected to the outer surface of the fractionation device body. One end of the outlet pipe is fixedly connected to the outer surface of the heating evaporation box.

[0004] The aforementioned patent describes an oil fractionation device. In practical applications, dirt and impurities tend to accumulate on the inner wall of the oil outlet pipe of the fractionation tower. If not cleaned in time, this can cause pipe blockage. A blockage-clearing mechanism can be designed for the pipe of the fractionation tower to clear the blockage more quickly. Utility Model Content

[0005] The purpose of this invention is to provide a non-finished petroleum product processing and fractionation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a non-finished petroleum product processing fractionation device, comprising a fractionation tower body, an oil outlet pipe, an outlet, and a blockage removal mechanism. An oil outlet pipe is installed on the side of the fractionation tower body. The oil outlet pipe is a T-shaped pipe, with the bottom opening of the oil outlet pipe serving as the outlet. A blockage removal mechanism is provided at the tail end of the oil outlet pipe. The blockage removal mechanism includes a threaded port, a receiving pipe, a blockage removal piston, a first magnet, a rubber sleeve, a control sleeve, and a second magnet. The tail end of the oil outlet pipe has a threaded port. The threaded end is threaded to the connector at the beginning of the receiving tube, connecting the receiving tube to the oil outlet pipe. A clearing piston is movably nested inside the receiving tube, and can move within both the receiving tube and the oil outlet pipe. A first magnet is embedded in the outer wall of the clearing piston, and a rubber sleeve is fitted on the outer surface of the clearing piston, allowing it to fit tightly against the inner wall of the oil outlet pipe. A control sleeve is movably fitted onto the surface of the oil outlet pipe, and a second magnet is embedded in the inner wall of the control sleeve, allowing it to magnetically attract the first magnet.

[0007] Preferably, the length of the receiving tube exceeds the length of the unblocking piston.

[0008] Preferably, the unblocking piston has a hollow tube structure.

[0009] Preferably, a magnetic sheet is attached to the tail end of the storage tube, and the magnetic sheet can be magnetically attracted to the first magnet.

[0010] Preferably, the first magnet is made entirely of AlNiCo magnet.

[0011] Preferably, the inner diameter of the oil outlet pipe inlet is smaller than the outer diameter of the rubber sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a blockage-clearing mechanism at the end of the oil outlet pipe. By fitting a control sleeve onto the surface of the receiving pipe, the second magnet and the first magnet are magnetically attracted to each other. Under magnetic force, the control sleeve controls the blockage-clearing piston to move into the oil outlet pipe from the outside. Subsequently, the control sleeve reciprocates along the surface of the oil outlet pipe to control the movement of the blockage-clearing piston inside the pipe. The piston scrapes away the dirt adhering to the inner wall of the oil outlet pipe through the rubber sleeve, thus clearing the blockage. The operation is quick and efficient, and the pipe does not need to be disassembled during the blockage-clearing process, reducing the downtime for cleaning the main body of the distillation tower and improving processing efficiency.

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 This utility model provides a non-finished petroleum product processing fractionation device, including a fractionation tower body 1, an oil outlet pipe 2, an outlet 3, and a blockage removal mechanism 4. The oil outlet pipe 2 is installed on the side of the fractionation tower body 1. The oil outlet pipe 2 adopts a T-shaped pipe. The bottom opening of the oil outlet pipe 2 is the outlet 3. The end of the oil outlet pipe 2 is equipped with a blockage removal mechanism 4.

[0023] Please see Figure 2-6 This utility model provides a non-finished petroleum product processing and fractionation device. The unblocking mechanism 4 includes a threaded port 41, a receiving tube 42, an unblocking piston 43, a first magnet 44, a rubber sleeve 45, a control sleeve 46, and a second magnet 47. The tail end of the oil outlet pipe 2 has a threaded port 41, which is threadedly connected to the head end connector of the receiving tube 42, so that the receiving tube 42 and the oil outlet pipe 2 are connected. The unblocking piston 43 is movably nested inside the receiving tube 42. The unblocking piston 43 can move inside the receiving tube 42 and the oil outlet pipe 2. A [missing information - likely a device name] is embedded on the outer wall of the unblocking piston 43. The first magnet 44 and the unblocking piston 43 are covered with a rubber sleeve 45 on their outer surface. The unblocking piston 43 is tightly fitted to the inner wall of the oil outlet pipe 2 through the rubber sleeve 45, so that the unblocking piston 43 can scrape off the dirt attached to the inner wall of the oil outlet pipe 2 through the rubber sleeve 45, thereby realizing the unblocking function. The control sleeve 46 is movably fitted on the surface of the oil outlet pipe 2. The inner wall of the control sleeve 46 is embedded with a second magnet 47. The second magnet 47 can be magnetically attracted to the first magnet 44. Under the action of magnetic force, the control sleeve 46 can control the unblocking piston 43 to move along the inside of the oil outlet pipe 2 from the outside to perform the unblocking action.

[0024] To further explain, the length of the receiving pipe 42 exceeds the length of the unblocking piston 43. When the unblocking piston 43 is idle, it can stop inside the receiving pipe 42 without affecting the normal operation of the oil outlet pipe 2.

[0025] To further explain, the unblocking piston 43 has a hollow tube structure to reduce its weight, allowing it to move more effectively through magnetic control.

[0026] To further explain, a magnetic sheet 48 is attached to the tail of the receiving tube 42. The magnetic sheet 48 can be magnetically attracted to the first magnet 44, so that the unblocking piston 43 can be magnetically attracted and fixed inside the receiving tube 42, and is not easy to move into the oil outlet pipe 2 on its own.

[0027] To further explain, the first magnet component 44 is made entirely of AlNiCo magnets. AlNiCo magnets have a small temperature coefficient, which makes the magnetic properties of the first magnet component 44 less affected by temperature changes, and can maintain relatively stable magnetic properties in the environment of the oil outlet pipe 2.

[0028] To further explain, the inner diameter of the oil outlet pipe 2 inlet is smaller than the outer diameter of the rubber sleeve 45 to prevent the unblocking piston 43 from accidentally falling into the fractionation tower body 1.

[0029] The working principle is as follows:

[0030] First, during the operation of the main body 1 of the fractionation tower, the fractionated oil will be discharged out through the outlet 3 via the oil outlet pipe 2. After a period of operation, dirt and impurities are easily accumulated on the inner wall of the oil outlet pipe 2. If it is not cleaned in time, it will cause the pipe to become blocked.

[0031] Secondly, by setting a blockage-clearing mechanism 4 at the end of the oil outlet pipe 2, during the blockage-clearing operation, the control sleeve 46 is first fitted onto the surface of the receiving pipe 42, so that the second magnet 47 and the first magnet 44 are magnetically attracted. At this time, the control sleeve 46 can control the blockage-clearing piston 43 to move into the oil outlet pipe 2 from the outside under the action of the magnetic force. Then, the control sleeve 46 is operated to move back and forth along the surface of the oil outlet pipe 2 to control the blockage-clearing piston 43 to move inside the oil outlet pipe 2, so that the blockage-clearing piston 43 can scrape off the dirt attached to the inner wall of the oil outlet pipe 2 through the rubber sleeve 45, thereby achieving blockage clearing. The operation is quick and there is no need to disassemble the pipe during the blockage clearing process, which reduces the downtime cleaning time of the fractionation tower body 1 and thus improves the processing efficiency.

[0032] Third, after the unblocking mechanism 4 is used up, the operating control sleeve 46 controls the unblocking piston 43 to move into the receiving tube 42. At this time, the magnetic sheet 48 and the first magnet 44 are magnetically attracted, so that the unblocking piston 43 can be magnetically attracted and fixed inside the receiving tube 42, and it is not easy for it to move into the oil outlet pipe 2 on its own, so as not to affect the normal operation of the oil outlet pipe 2.

[0033] Fourth, when cleaning and maintenance are required, the receiving tube 42 can be unscrewed from the inside of the threaded port 41 to remove the unblocking mechanism 4 for cleaning and maintenance, which is convenient to operate.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
