[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Referring to Figures 1-4 A tubular reactor with stirring structure comprises a pipe body 1, a mounting frame 2 is arranged at the pipe opening of the pipe body 1 through a blocking mechanism, a plurality of extrusion grooves 9 are arranged on the mounting frame 2, a positioning block 10 is arranged in each extrusion groove 9 through an extrusion mechanism, and a plurality of positioning holes 11 corresponding to the positioning blocks 10 are arranged on the pipe body 1. A fixing frame 6 is arranged inside the pipe body 1, the fixing frame 6 comprises a transmission cavity 13 and a rotating cavity 14, a transmission shaft 15 is arranged in the transmission cavity 13, a rotating shaft 4 is arranged on the mounting frame 2 through a rotating groove 3, a plurality of blades 5 are arranged on the rotating shaft 4, and the rotating shaft 4 is connected with the transmission shaft 15 through a plug-in mechanism. A connecting shaft 20 extending into the transmission cavity 13 and outside the pipe body 1 is arranged in the rotating cavity 14, the transmission shaft 15 is connected with the connecting shaft 20 through a transmission mechanism, and a feedback assembly 7 is arranged on the connecting shaft 20.

[0023] The blocking mechanism comprises a limiting ring 8 arranged on the inner wall of the pipe body 1, and sealing assemblies are arranged between the mounting frame 2 and the pipe body 1 and the limiting ring 8. The limiting ring 8 plays a certain blocking role, that is, even if the positioning block 10 is separated from the positioning hole 11, the mounting frame 2 will not continue to penetrate into the inside of the pipe body 1.

[0024] The extrusion mechanism comprises a spring 12 arranged in the extrusion groove 9, and the spring 12 is elastically connected with the outer wall of the positioning block 10 and the inner wall of the extrusion groove 9 at both ends. The spring 12 realizes extrusion of the positioning block 10, ensures that the positioning block 10 can enter the positioning hole 11, and ensures that the mounting frame 2 is stably arranged in the pipe body 1.

[0025] The plug-in mechanism comprises a synchronous rod 16 arranged on the rotating shaft 4, and a synchronous groove 17 corresponding to the synchronous rod 16 is arranged on the transmission shaft 15. The vertical section view of the synchronous rod 16 and the synchronous groove 17 is rectangular, so that when the synchronous rod 16 is in the synchronous groove 17, the synchronous rod 16 can drive the transmission shaft 15 to rotate synchronously.

[0026] The transmission mechanism comprises a driving gear 18 arranged on the transmission shaft 15, a transmission gear 19 is arranged on the connecting shaft 20, and the driving gear 18 is engaged with the transmission gear 19. The driving gear 18 and the transmission gear 19 are both conical gears, and the two gears are in a vertical engagement relationship.

[0027] The outer wall of the positioning block 10 is provided with an inclined portion, and the inner wall of the pipe body 1 is also provided with an inclined portion, and the inclined portions on the positioning block 10 and the pipe body 1 are polished.

[0028] When the mounting frame 2 needs to be installed into the pipe body 1, the mounting frame 2 is pushed into the pipe body 1. In this process, because the outer wall of the positioning block 10 and the inner wall of the pipe body 1 are both provided with inclined portions and are polished, when the mounting frame 2 is pushed, the inner wall of the pipe body 1 extrudes the positioning block 10, and the positioning block 10 is pressed into the extrusion groove 9, and at this time, the spring 12 is compressed. When the mounting frame 2 continues to advance to a certain position, the positioning block 10 is extruded out of the extrusion groove 9 under the elastic action of the spring 12 and enters the corresponding positioning hole 11 on the pipe body 1, so that the stable installation of the mounting frame 2 in the pipe body 1 is realized.

[0029] When the pipe body 1 enters the object, the blade 5 drives the rotating shaft 4 to rotate, and the synchronous rod 16 on the rotating shaft 4 drives the transmission shaft 15 to rotate synchronously. The driving gear 18 on the transmission shaft 15 meshes with the transmission gear 19 on the connecting shaft 20, and because the driving gear 18 and the transmission gear 19 are both conical gears and vertically mesh, the rotation of the transmission shaft 15 drives the connecting shaft 20 to rotate through the transmission action of the driving gear 18 and the transmission gear 19.

[0030] The rotation of the connecting shaft 20 can drive the feedback assembly 7 (composed of components such as ribbons) to rotate, so that whether the rotating shaft 4 and the blade 5 rotate and their rotation speed can be directly understood.

[0031] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
