Abstract

The invention discloses a refrigeration barrel and a refrigeration method. The refrigeration barrel comprises a barrel body, a barrel cover, a guide rod base, a guide locating rod, a liquid level adjusting buoy and a buoy press assembly. The barrel cover is arranged on the barrel body in a covering mode. The guide rod base is arranged on the inner bottom surface of the barrel body. The bottom endof the guide locating rod is connected with the guide rod base, and the guide locating rod is located on the axis of the barrel body. The liquid level adjusting buoy comprises a buoy guide hole, and the liquid level adjusting buoy sleeves the guide locating rod through the buoy guide hole. The buoy press assembly is located on the top of the liquid level adjusting buoy and used for detachably fixing the liquid level adjusting buoy to the inner bottom surface of the barrel body. The refrigeration barrel can be reused, the consumption of refrigerating fluid is reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a liquid nitrogen barrel and a freezing method. Background technique [0002] In the prior art, when a ship is built, some bearings of the shaft system are required to be installed after freezing. The specific operation method is to put the entire bearing into a liquid nitrogen bucket, add a large amount of liquid nitrogen, submerge the entire bearing, and freeze it for a period of time. , take the bearing out of the liquid nitrogen by using the thick steel wire pre-set on the bearing, and finally install the bearing in the corresponding position. [0003] However, the freezing method of marine shafting bearings in the prior art consumes a lot of liquid nitrogen; steel wires tend to become brittle and weakened after freezing, and there are safety risks when taking out or hoisting the bearings. [0004] How to design a marine liquid nitrogen tank tooling to make the freezing...
