[0004] The above device realizes the function of cleaning the inner wall of the reactor by using a scraper. However, in order to clean it thoroughly, the scraper needs to fit the inner wall of the reactor, but its position is fixed. The long-term friction between the scraper and the inner wall of the reactor will cause damage to the reactor, and there is room for improvement. Content of the Utility Model

[0005] The purpose of the utility model is to provide a self-cleaning stirring reactor for polypropylene production to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A self-cleaning stirring reactor for polypropylene production, including a kettle cover, characterized in that: a cleaning component is installed inside the kettle cover, the cleaning component includes a stirring frame rotatably connected to the middle of the kettle cover, the cleaning component includes a mounting rod fixedly sleeved on the top of the circumferential outer wall of the stirring frame, a limiting groove is opened at both ends of the mounting rod, a mounting ring one is slidably connected inside each of the two limiting grooves, a cleaning plate is fixedly connected to one side of the bottom outer wall of each of the two mounting rings one, and a same extension column is fixedly connected to the middle of the inner wall at both ends of the mounting ring one, and the extension column is set to be cylindrical.

[0007] As a further optimization of the present technical solution, a driving frame is slidably inserted in the middle of the kettle cover. The outer wall of the bottom of the driving frame is coaxially fixed with a second mounting ring. The outer wall of the bottom of the second mounting ring is rotatably connected to a rotating ring in the center. The outer wall of the bottom of the rotating ring is fixedly connected with two inclined driving rings. The two driving rings are respectively sleeved outside the two extension columns. On both sides of the outer wall of the top of the kettle cover, a hydraulic cylinder is fixedly installed.

[0008] As a further optimization of the present technical solution, the bottom of the kettle cover is detachably connected to the kettle body. One end of the bottom of the stirring frame is rotatably connected to the inner wall of the bottom of the kettle body.

[0009] It can drive the cleaning plate for cleaning the inner wall of the kettle body to move away from or close to the inner wall of the kettle body at will, ensuring that the cleaning plate will only scrape the inner wall of the kettle body during use, and avoiding the problem of wear caused by long-term friction between the two. By starting the two hydraulic cylinders to drive the driving frame to move upward, the second mounting ring and the rotating ring connected to the driving frame will also move synchronously. The rotating ring can drive the extension column to approach the inner wall of the kettle body through the inclined driving ring. The first mounting ring will also follow the extension column and slide along the limiting groove until the cleaning plate fixed to the bottom of the first mounting ring fits the inner wall of the kettle body. Also, because the rotating ring and the second mounting ring connected to the driving ring are rotatably connected, the operation of the assembly can be ensured not to be affected.

A limiting gear ring is coaxially fixed to the inner wall of the top of the kettle cover. The two driven gear rings are both meshed with the limiting gear ring.

[0012] The motor drives the stirring frame to rotate inside the kettle body. The mounting rod fixed to the top of the stirring frame will also rotate synchronously. The stirring sub-frames restricted at both ends of the mounting rod can perform a revolution. At this time, the driven gear rings will revolve synchronously, and they will rotate on their own when rotating due to the meshing with the limiting gear ring. Cooperating with the stirring frame can greatly increase the stirring effect.

Specific Embodiments

[0023] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the utility model.

[0024] The utility model provides technical solutions: AsFigure 1 , Figure 3 As shown in FIGS. 3 and 4, in this embodiment, a self-cleaning polypropylene production stirring reactor includes a kettle cover 1, and is characterized in that: a cleaning component 5 is installed inside the kettle cover 1. The cleaning component 5 includes a stirring frame 4 rotatably connected to the middle of the kettle cover 1. The cleaning component 5 includes a mounting rod 501 fixedly sleeved on the top of the circumferential outer wall of the stirring frame 4. A limiting groove 502 is provided at each of the two ends of the mounting rod 501. A first mounting ring 503 is slidably connected inside each of the two limiting grooves 502. A cleaning plate 504 is fixedly connected to one side of the bottom outer wall of the two first mounting rings 503. A same extension column 505 is fixedly connected to the middle of the inner walls at both ends of the first mounting ring 503. The extension column 505 is cylindrical.

[0025] A driving frame 506 is slidably inserted into the middle of the kettle cover 1. A second mounting ring 507 is coaxially fixed to the bottom outer wall of the driving frame 506. A rotating ring 508 is rotatably connected to the middle of the bottom outer wall of the second mounting ring 507. Two inclined driving rings 509 are fixedly connected to the bottom outer wall of the rotating ring 508. The two driving rings 509 are respectively slidably sleeved outside the two extension columns 505. A hydraulic cylinder 510 is fixedly installed on both sides of the top outer wall of the kettle cover 1. The output ends of the two hydraulic cylinders 510 are respectively fixedly connected to both sides of the top outer wall of the driving frame 506.

[0026] By starting the two hydraulic cylinders 510 to drive the driving frame 506 to move upward, the second mounting ring 507 and the rotating ring 508 connected to the driving frame 506 will also move synchronously. The rotating ring 508 can drive the extension column 505 to approach the inner wall of the kettle body 2 through the inclined driving ring 509. The first mounting ring 503 will also slide along the limiting groove 502 following the extension column 505 until the cleaning plate 504 fixed to the bottom of the first mounting ring 503 fits against the inner wall of the kettle body 2. Also, because the rotating ring 508 and the second mounting ring 507 connected to the driving ring 509 are rotatably connected, the operation of the component can be ensured not to be affected. On the contrary, the cleaning plate 504 can also be controlled to move away from the kettle body 2 through the hydraulic cylinder 510.

[0027] As Figure 1 shown in FIGS. 1 and 2, the kettle body 2 is detachably connected to the bottom of the kettle cover 1. One end of the bottom of the stirring frame 4 is rotatably connected to the inner wall of the bottom of the kettle body 2, making the state of the stirring frame 4 more stable. A feed inlet (not shown in the figure) is provided outside the kettle body 2, and a discharge outlet is provided at the bottom.

[0028] As Figure 2 and Figure 4 shown, an efficiency enhancing component 6 is installed inside the mounting rod 501. The efficiency enhancing component 6 includes two stirring sub-frames 601 rotatably connected to both sides of the mounting rod 501. The two stirring sub-frames 601 are arranged in a staggered manner with the stirring frame 4.

[0029] A driven gear ring 602 is fixedly sleeved on the top of the circumferential outer wall of each of the two stirring auxiliary frames 601. A limiting gear ring 603 is coaxially fixed on the inner wall of the top of the kettle lid 1. Both of the two driven gear rings 602 are meshed with the limiting gear ring 603.

[0030] Start the motor 3 on the top of the kettle lid 1. The motor 3 will drive the stirring frame 4 to rotate inside the kettle body 2. The mounting rod 501 fixed on the top of the stirring frame 4 will also rotate synchronously. The stirring auxiliary frames 601 restricted at both ends of the mounting rod 501 can perform revolution. At this time, the driven gear ring 602 will revolve synchronously. When it rotates, it will be meshed by the limiting gear ring 603 to perform self-rotation. Cooperating with the stirring frame 4 can greatly increase the stirring effect.

[0031] As Figure 1 As shown in and Figure 2, a reinforcing plate is fixedly sleeved on the bottom of the circumferential outer wall of the stirring frame 4. One end of the bottom of each of the two stirring auxiliary frames 601 is rotatably connected to the top outer wall of the reinforcing plate, making the state of the stirring auxiliary frame 601 stable enough.

[0032] As Figure 1 As shown, a motor 3 is fixedly installed on the top outer wall of the kettle lid 1. The rotating shaft of the motor 3 and one end of the stirring frame 4 are coaxially fixed.

[0033] The utility model provides a stirring reaction kettle for polypropylene production that can be self-cleaned. The specific working principle is as follows:

[0034] When the device works, by starting the motor 3 on the top of the kettle lid 1, the motor 3 will drive the stirring frame 4 to rotate inside the kettle body 2. The mounting rod 501 fixed on the top of the stirring frame 4 will also rotate synchronously. The stirring auxiliary frames 601 restricted at both ends of the mounting rod 501 can perform revolution. At this time, the driven gear ring 602 will revolve synchronously. When it rotates, it will be meshed by the limiting gear ring 603 to perform self-rotation. Cooperating with the stirring frame 4 can greatly increase the stirring effect. When discharging, as long as two hydraulic cylinders 510 are started to drive the driving frame 506 to move upward, the mounting ring two 507 and the rotating ring 508 connected to the driving frame 506 will also move synchronously. The rotating ring 508 can drive the extension column 505 to approach the inner wall of the kettle body 2 through the inclined driving ring 509. The mounting ring one 503 will also follow the extension column 505 to slide along the limiting groove 502 until the cleaning plate 504 fixed at the bottom of the mounting ring one 503 fits the inner wall of the kettle body 2. Also, because the rotating ring 508 and the mounting ring two 507 connected to the driving ring 509 are rotatably connected, it can ensure that the operation of the components is not affected. On the contrary, the cleaning plate 504 can also be controlled to be away from the kettle body 2 through the hydraulic cylinder 510.
