Embodiment
Below in conjunction with Figure of description and embodiment, the utility model liquid changing device is described in detail:
As shown in Figure 1, a kind of liquid changing device, comprise the uncovered cylindrical shell in upper end 1, cylindrical shell 1 lower end sidewall is provided with the outlet conduit 2 be communicated with it, upper end sidewall is provided with the water inlet pipe 3 be communicated with it, the import of water inlet pipe 3 is connected with flexible pipe 4, cylindrical shell 1 upper end is provided with cover 5, cover 5 cross section is in falling convex shape, wherein be formed centrally center hole, the inwall of center hole is circumferentially formed inner groovy, inner seal ring 6 is placed in inner groovy, pull bar 7 stretches in cylindrical shell 1 through the center hole of cover 5, one end that pull bar 7 stretches in cylindrical shell 1 connects piston cap 8, the outer wall of piston cap 8 is circumferentially formed outer groove, exterior seal ring 9 is placed in outer groove, one end that pull bar 7 is positioned at outside cover 5 forms handle 10.
Described outlet conduit 2 is horizontally disposed with.
Described water inlet pipe 3 is in " ┛ " type.
Described outlet conduit 2 and water inlet pipe 3 are positioned at the heteropleural of cylindrical shell 1.
Described cover 5 is threaded with between cylindrical shell 1.
Described pull bar 7 is threaded with between piston cap 8.
The external diameter of described exterior seal ring 9 coordinates with the inner diameter seal of cylindrical shell 1.
The internal diameter of described inner seal ring 6 and the external diameter of pull bar 7 are sealed and matched.
Using method of the present utility model:
Flexible pipe 4 is put into liquid container 11 to be changed by (I), and outlet conduit, as far as possible close to the bottom of liquid container 11 to be changed, is aimed at waste liquor recycling bin 12 or connecting hose discharge by the entrance of flexible pipe 4;
(II) holds handle 10, and upwards lift pull bar 7, pull bar 7 drives piston cap 8 to move up, until peak, till namely contacting cover 5 bottom surface; Outer wall due to piston cap 8 is provided with exterior seal ring 9, and the center bore inner wall of cover 5 is provided with inner seal ring 6, so the space that between cylindrical shell 1 inner carrier lid 8 to cover 5, formation one is airtight, under the effect that piston cap 8 is moved, is extruded by the air in cylindrical shell 1;
