Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
The present embodiment cavitation pot plan view as shown in Figure 1.This cavitation pot is comprised of urceolus 1, inner core 2, tank platform 3, cover 4, overflow plate 5, current plate 6, inducer pipe 7, outlet section pipe 8, urceolus waste pipe 9, inner core waste pipe 10, vacuum pump connecting tube 11, Instrument connection part 12.Wherein urceolus 1, inner core 2, tank platform 3, cover 4, overflow plate 5, inducer pipe 7, outlet section pipe 8, urceolus waste pipe 9, inner core waste pipe 10, vacuum pump connecting tube 11, Instrument connection part 12 all adopt all-transparent plexiglass to process, and current plate 6 adopts stainless steel to process.
At the bottom of urceolus 1 comprises tin and annulus cylindricality stack shell, the cylinder end adopts digs out an arc surface from a cylindrical all-transparent plexiglass integral body, so that urceolus bottom stress equalization, then at place, this circular arc summit processing urceolus weep hole and with the barrel at the bottom of 1 of urceolus, process the pipeline being connected with urceolus weep hole, then cylinder primer is sticked at it the annulus pillar buoy of urceolus 1.On stack shell inwall, process for the step-like projection of current plate is installed.Process urceolus water inlet, osculum and the top weep hole of urceolus 1, and at the flange of the gluing uniform bolt hole in stack shell top.
