DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The present application embodiment discloses a hyperbranched polymer reactor. Figure 1 and Figure 2 The reactor of hyperbranched polymer comprises a reactor body 1, a stirring assembly 2 is arranged in the reactor body 1, and a sampling port 11 is opened on the top side of the reactor body 1, a sampling tube 3 is installed in the sampling port 11, the bottom end of the sampling tube 3 has an opening, and the top end of the sampling tube 3 is connected with a suction assembly 4. With the help of the stirring assembly 2, the mixing of the sample in the reactor body 1 can be guaranteed; before sampling, the operator controls the lifting of the sampling tube 3 to adjust the height of the bottom end of the sampling tube 3, and after the bottom end of the sampling tube 3 reaches the predetermined sampling height, the suction assembly 4 is started to extract the sample at the bottom end of the sampling tube 3, thereby realizing the sampling of the sample; the operator can realize sampling at different heights by adjusting the lifting of the sampling tube 3, which improves the problem of difficulty in adjusting the sampling height as a whole.

[0035] A feeding port is provided on the upper side of the kettle body 1 , through which an operator can feed materials to the upper side of the kettle body 1 . A feeding pipe is provided on the lower side of the kettle body 1 , through which the hyperbranched polymer in the kettle body 1 can flow out of the kettle body 1 .

[0036] Reference Figure 1 and Figure 2 The suction assembly 4 includes a connecting pipe 41, a sample tank 42 and an air pump 43. The connecting pipe 41 is an elastic plastic tube. One end of the connecting pipe 41 is connected to the side wall of the sample tank 42, and the other end is connected to the upper end of the sampling tube 3. An air pump 431 is connected between the air inlet of the air pump 43 and the upper side of the sample tank 42. A mounting plate 12 is fixedly welded to the outside of the kettle body 1, and the sample tank 42 and the air pump 43 are both fixedly mounted on the upper side of the mounting plate 12. When the operator starts the air pump 43, the air pump 43 can generate negative pressure in the sample tank 42, the connecting pipe 41 and the sampling tube 3, so that the sample in the kettle body 1 enters the sample tank 42 from the sampling tube 3 and the connecting pipe 41 in turn; the connecting pipe 41 is connected to the upper end of the sampling tube 3, which reduces the sample from entering the air pump 43.

[0037] The bottom side of the sample tank 42 is connected to a discharge pipe 5, and a valve 51 is provided on the discharge pipe 5. When the operator opens the valve 51, the sample can flow out of the discharge pipe 5, and the operator can conveniently receive the sample.

[0038] The sample tank 42 is provided with a transparent observation window 421 , which may be made of plastic or glass. The observation window 421 allows the operator to conveniently observe the quantity of the sample in the sample tank 42 , and the operator can turn off the vacuum pump 43 in time to avoid drawing the sample into the vacuum pump 43 .

[0039] Reference Figure 1 and Figure 2 A lifting assembly 6 for controlling the lifting of the sampling tube 3 is provided on the upper side of the kettle body 1. With the help of the lifting assembly 6, the height of the sampling tube 3 can be adjusted. A guide ring 7 is welded on the upper side of the kettle body 1. The sampling tube 3 is located in the guide ring 7. The guide ring 7 can guide the lifting of the sampling tube 3.

[0040] Reference Figure 3 and Figure 4 The lifting assembly 6 includes a driving motor 61 and a gear 62. The driving motor 61 is fixedly mounted on the upper side of the kettle body 1. The gear 62 is coaxially welded with the output shaft of the driving motor 61. A rack 31 is welded on the sampling tube 3. The rack 31 is parallel to the sampling tube 3, and the rack 31 is meshed with the gear 62. When the operator starts the driving motor 61, the driving motor 61 drives the gear 62 to rotate. When the gear 62 rotates, the rack 31 can drive the sampling tube 3 to rise. When the operator controls the driving motor 61 to rotate in the opposite direction, the rack 31 can drive the sampling tube 3 to descend, thereby realizing the control of the lifting of the sampling tube 3.

[0041] In order to facilitate the rack 31 to pass through the guide ring 7, a groove 71 is opened on the inner wall of the guide ring 7, and the rack 31 is located in the slide groove. When the rack 31 is raised or lowered, the rack 31 can slide through the groove 71, reducing the interference of the guide ring 7 on the rack 31.

[0042] The stirring assembly 2 includes a stirring motor 21, a stirring shaft 22 and a stirring blade 23. The stirring motor 21 is fixedly mounted on the upper side of the kettle body 1, and the stirring shaft 22 is coaxially welded with the output shaft of the stirring motor 21. The stirring shaft 22 is vertical, and a plurality of stirring blades 23 are provided, and the stirring blades 23 are welded to the stirring shaft 22. Starting the stirring motor 21 can ensure that the stirring blades 23 stir the kettle body 1.

[0043] The sampling tube 3 is vertical, and the distance between the sampling tube 3 and the stirring shaft 22 is greater than the length of the stirring blade 23. When the stirring shaft 22 rotates, the stirring blade 23 can be prevented from touching the sampling tube 3, thereby protecting the stirring blade 23 and the sampling tube 3.

[0044] The implementation principle of the reactor for producing hyperbranched polymers in the embodiment of the present application is as follows: before sampling, the operator controls the lifting and lowering of the sampling tube 3 to adjust the height of the bottom end of the sampling tube 3. After the bottom end of the sampling tube 3 reaches a predetermined sampling height, the suction assembly 4 is started to extract the sample at the bottom end of the sampling tube 3, thereby realizing the sampling of the sample; the operator can realize sampling at different height positions by adjusting the lifting and lowering of the sampling tube 3, thereby improving the problem of difficulty in adjusting the sampling height as a whole.

[0045] The above are all optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
