Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): please refer to fig. 1, the utility model provides a condensation reflux ware for bioreactor, including outer pipe 3, the bottom welding of outer pipe 3 has base 2, the top of outer pipe 3 is fixed to be inserted and is equipped with inlayer pipe 4, the baffle 5 that is used for realizing fluid spiral to go forward has been placed to the inside of inlayer pipe 4, the bottom of inlayer pipe 4 stretches into in outer pipe 3 and welds mutually with base 2, outer pipe 3, enclose between inlayer pipe 4 and the base 2 and close and form annular cavity, the welding has condensate outlet 8 and the condensate inlet 9 with the annular cavity intercommunication on the outer pipe 3, wherein, condensate outlet 8 is located the one end that is close to outlet duct 7 on outer pipe 3, condensate inlet 9 is located the one end that is close to intake pipe 1 on outer pipe 3. An air inlet pipe 1 communicated with an inner layer pipe 4 is fixedly inserted in the base 2, the top end of the inner layer pipe 4 extends out of the outer layer pipe 3 and then is detachably fixedly connected with a screwing cover 6, and an air outlet pipe 7 communicated with the inner layer pipe 4 is fixedly inserted in the screwing cover 6.

Wherein, the outer wall of the top end of the inner tube 4 is provided with an external thread, and the tightening cover 6 is provided with an internal thread matched with the external thread; the external thread adopts the design of 55 cylindrical pipe threads, and no radial clearance exists between the inner layer pipe 4 of the screwing cover 6 and the screwed threads, so that the tightness is good.
