For example, with reference to fig. 4, a schematic view of the construction is shown in which the angles β between the axis of the connecting sleeve and the top wall of the tank 1 are 90 °, 60 °, 45 ° and 30 °, respectively. In practice, the hole diameter of the first connection hole is the same as the hole diameter of the lower end surface of the connection sleeve 8 when β is 30 °. When the connecting sleeve 8 at the time of β ═ 45 ° needs to be installed, only the size of the flange needs to be changed, so that the connecting sleeve and the first connecting hole are connected in a sealing manner through the flange.
