Description

Technical Field

[0001] This utility model relates to the field of polypropylene separation technology, specifically a polypropylene three-phase separator. Background Technology

[0002] Polypropylene is a semi-crystalline thermoplastic polymer made from propylene monomers through an addition polymerization reaction. In the production process of polypropylene, the product obtained after the polymerization reaction is a three-phase mixture of gas, liquid and solid. It needs to be separated to obtain pure polypropylene products. Therefore, a three-phase separator is required in the subsequent separation process.

[0003] For example, a three-phase separator according to Chinese patent application number CN202320014237.X can be used to separate polypropylene. The separator includes a tank with an internal cavity, a sedimentation separation zone within the cavity, and an independent oil chamber and water chamber downstream of the sedimentation separation zone. The oil chamber is separated from the sedimentation separation zone by a first overflow weir plate, and an oil outlet is connected to the oil chamber. The water chamber is separated from the sedimentation separation zone by a first transverse partition plate, and the sedimentation separation zone is connected to the water chamber by a bottom flow channel. A second overflow weir plate is installed in the water chamber, forming a buffer cavity between the second overflow weir plate and the first transverse partition plate. This three-phase separation, by configuring the second overflow weir plate, allows for stable control of the oil-water interface, ensuring stable separation and good versatility. It can reduce or even avoid the impact of operating condition fluctuations on the sedimentation separation process and prevent oil polymerization to form aged oil.

[0004] However, in actual use, the above-mentioned device accumulates both the solid particles and liquid separated from polypropylene in the water chamber, which cannot fully guarantee the separation and discharge of solid and liquid particles, thus having limitations and reducing the operational stability of the equipment.

A circular frame is embedded in the bottom of the filter cylinder and is fixedly provided at the bottom of the receiving pile. The inside of the filter cylinder and the inside of the circular frame are interconnected, which facilitates the filtration and separation of solid and liquid through the filter cylinder, while the liquid flows into the circular frame.

A cyclone separator body 3 is fixedly provided at the top inside the vertical cylindrical shell 1. The cyclone separator body 3 is a prior art technology. Its working principle is to rely on the rotational motion caused by the tangential introduction of airflow to make solid particles or liquid droplets with large inertial centrifugal force throw towards the outer wall surface to separate them, thereby realizing the separation of gas and solid-liquid in polypropylene polymer.

[0026] The bottom end of the connecting pipe 5 penetrates through the vertical cylindrical shell 1 and communicates with the interior of the cyclone separator body 3. The exhaust port of the cyclone separator body 3 is fixedly provided with an exhaust pipe 7, and the top end of the exhaust pipe 7 penetrates through the vertical cylindrical shell 1 and is located at the top center of the vertical cylindrical shell 1, which facilitates the cyclone separator body 3 to separate the polypropylene polymer into gas and solid-liquid components. An electric valve 6 is fixedly provided on the connecting pipe 5, which facilitates the polypropylene polymer inside the feeding frame 2 to enter the interior of the cyclone separator body 3 through the connecting pipe 5. The front hinge of the vertical cylindrical shell 1 is connected to a cylinder door 11. Connecting columns 8 are fixed on both sides of the vertical cylindrical shell 1. A T-shaped support pile 9 is fixedly provided at the end of the connecting column 8 away from the vertical cylindrical shell 1. Two front and rear distributed moving wheels 10 are fixedly provided at the bottom of the T-shaped support pile 9, which facilitates the movement of this utility model.

[0027] like Figure 2-5 As shown, the bottom of the vertical cylindrical shell 1 is provided with a solid-liquid separation component 4 for fully separating solids and liquids. The solid-liquid separation component 4 includes a separation cylinder 41, which is fixedly embedded in the bottom of the vertical cylindrical shell 1. The bottom of the separation cylinder 41 is connected to a filter cylinder 42 via a bearing. Four scrapers 43 are fixedly provided on the bottom of the outer wall of the filter cylinder 42. Several crossbars 44 are fixedly provided on the outer wall of the filter cylinder 42. The bottom of the scrapers 43 is in contact with the bottom of the separation cylinder 41. The positions of the crossbars 44 and the four scrapers 43 are respectively corresponding. Openings are provided on both sides of the bottom of the separation cylinder 41, and the two openings are respectively located on both sides of the filter cylinder 42. A cylinder cover 412 is connected to the inside of the opening via a thread, which makes it easy to unscrew the cylinder cover 412 and discharge the solids through the opening.

[0028] Two connecting rods 49 are fixedly provided on the inner wall of the filter cylinder 42, and a common receiving pile 46 is fixedly provided between the two connecting rods 49. A circular frame 45 is embedded in the bottom of the filter cylinder 42 and is fixedly provided at the bottom of the receiving pile 46. The interior of the filter cylinder 42 and the interior of the circular frame 45 are interconnected, which facilitates the filtration and separation of solid and liquid through the filter cylinder 42. At the same time, the liquid flows into the circular frame 45. A liquid outlet pipe 410 is fixedly provided on the rear side of the circular frame 45, and a valve 411 is fixedly provided on the liquid outlet pipe 410. A connecting plate 47 is fixedly provided between the inner walls of the circular frame 45, and a motor 48 is fixedly provided on the top of the connecting plate 47. The output shaft of the motor 48 is fixedly connected to the center of the bottom of the receiving pile 46, which facilitates the motor 48 to drive the receiving pile 46 to rotate. A control panel 12 for controlling the operation of the electric valve 6, the cyclone separator body 3 and the motor 48 is fixedly provided on the top of the front side of one of the T-shaped support piles 9.

[0029] By setting up the solid-liquid separation component 4, polypropylene polymer is placed into the feeding frame 2. Then, the control panel 12 is operated to open the electric valve 6, and the cyclone separator body 3 and the motor 48 work simultaneously. The polypropylene polymer inside the feeding frame 2 enters the cyclone separator body 3 through the connecting pipe 5. Under the action of centrifugal force of high-speed rotation, the gas and liquid are further separated. The gas is thrown towards the center and flows upward, and is discharged from the exhaust pipe 7. The liquid and solid are thrown towards the outer wall and sink downward, entering the separation cylinder 41.

[0030] Liquid and solid fall to the top of filter cylinder 42 inside separation cylinder 41. After being filtered and separated by filter cylinder 42, the liquid flows into the filter cylinder 42 and enters the circular frame 45, while the solid slides down the filter cylinder 42 into the separation cylinder 41. At the same time, motor 48 drives the receiving pile 46 to rotate the filter cylinder 42. The rotation of filter cylinder 42 causes the scraper 43 on the outer wall and several crossbars 44 to rotate simultaneously. The rotation of crossbars 44 stirs the solid inside separation cylinder 41, so that the liquid attached to its surface is fully separated and flows through filter cylinder 42 into circular frame 45. Finally, opening valve 411 facilitates the discharge of liquid, and unscrewing the two cylinder caps 412 facilitates the discharge of the separated solid inside separation cylinder 41. This ensures that solid and liquid are fully separated and discharged, improves the operational stability of the equipment, and makes operation convenient.
