Comparative example 1
As shown in fig. 3, this comparative example provides a drip tube of the prior art, which includes a feed section 101 and an intermediate section 102.
Comparative example 2
As shown in fig. 4, this comparative example provides a drip tube of the prior art, which includes a feed section 101, an intermediate section 102, and a discharge section 103.
As can be seen from the comparison of the comparative examples 1 and 2 and the examples of the invention, the invention can avoid the phenomenon that part of monomers are polymerized to form residual dead glue due to sputtering to the inner wall of a reaction kettle in the process of dripping monomers by the cooperation of the first baffle plate group and the second baffle plate group with the dripping pipe body, namely, the dripping feed liquid flows down along the baffle plates by the arrangement of the baffle plates, so as to avoid the monomers from splashing to the kettle wall to form the dead glue residue.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
